+ request chunked encoding. Now only CRLF or bare LF are recognized as end
+ of line.
+ Added Lawrence Sebald to the AUTHORS file (iovec-based responses).
+ Check for PAGESIZE and PAGE_SIZE macros and check whether they can be used
+ for static variable initialization.
+ Include "MHD_config.h" before all other includes to set macros required to
+ be set before standard includes.
+ Chunked response: abort with error if application returns more data than
+ requested.
+ Monotonic clock: use only native clock on W32 as all other clocks are just
+ wrappers.
+ W32: fixed builds with MSVC, added projects for VS2022, added MSVC
+ universal project that use latest available toolset, use C17 if supported.
+ Chunked response: fixed calculation of number of bytes left to send.
+ microhttpd.h: doxy clarifications for sockets polling.
+ Updated HTTP statuses, methods, and headers names from the registries.
+ Further improved doxy for MHD_add_response_header().

+ Minor code readability improvements in MHD_set_connection_option().
+ Improved doxy for MHD_get_timeout().
+ Memorypool: minor code improvements. -EG
+
+September 2021
+ Improved system includes headers detection and usage. Removed unused
+ headers detection.
+ Added indirect calculation of maximum values at compile time by
+ using types size detection. These values are used only to mute
+ compiler warnings.
+ Fixed pre-compiler errors if various *_MAX macros defined with
+ non-digits symbols not readable for pre-compiler.
+ Limit number of used CPU cores in tests to 6, unless heavy tests are
+ enabled.
+ Disabled parallel tests with libcurl if heavy tests are enabled.
+ configure: removed '--enable-sanitizer' and added '--enable-sanitizers'
+ parameters. Added testing for supported sanitizers and enabling only
+ supported sanitizers.
+ Added support for run-time sanitizers settings for tests when
+ sanitizers are enabled.
+ Added support for undefined behavior sanitizer without run-time library.
+ Fixed various undefined behavior sanitizer detected errors, improved
+ portability.
+ Fixed how bitwise NOT is used with enum, fixed portability.
+ microhttpd.h: changed macros MHD_CONTENT_READER_* to use ssize_t.
+ test_postprocessor: added more check, improved error reporting, added
+ new test data.
+ postprocessor: fixed undefined behavior (memcpy(), memmove() with zero
+ size and NULL pointer).
+ Updated copyright year in W32 DLLs.
+ postprocessor: fixed empty key processing.
+ test_postprocessor: added tests with hex-encoded values.
+ postprocessor: fixed incomplete processing of the last part of hex-encoded
+ value if data was broken into certain sized pieces.
+ Used type specifiers for printf() from inttypes.h to improved compatibility
+ with various run-time libs. Fallback to standard values if type specifiers
+ are not defined.
+ Added detection of used run-time library (MSVCRT/UCRT) on W32.
+ testcurl: fixed incorrect case-insensitive match for method name. Method
+ name must be checked by using case-sensitive match.
+ microhttpd.h: clarified some doxy descriptions.
+ Prevented potential double sending of error responses.
+ Fixed application notification with MHD_REQUEST_TERMINATED_COMPLETED_OK
+ when error response has been sent (MHD_REQUEST_TERMINATED_WITH_ERROR is
+ used).
+ Avoid trying to send error response if response is already being sent.
+ Improved log error message when error response is processing. -EG
+
+August 2021
+ Silently drop "keep-alive" token from response "connection" header,
+ "keep-alive" cannot be enforced and always enabled if possible.
+ Further improved doxy for MHD_add_response_header().
+ Added detection of the "Date:" header in the response headers set by
+ app at response forming time.
+ Disallow space in response header name, allow tab in response header
+ value.
+ Added internal MHD_uint8_to_str_pad() function.
+ Used internal MHD_uint8_to_str_pad() in datestamp generation function.
+ Added detection and reporting of incorrect "Upgrade" responses. -EG
+ Fixed short busy waiting (up to one second) when connection is going
+ to be closed. -AI
+ Minor improvement for test_callback, test_get_chunked
+ Fixed chunked responses with known size.
+ Added two more tests for chunked response.
+ Fixed chunked responses with predefined data (without data callback).
+ Fixed calculation of the buffer size for the next response chunk.
+ Completely rewritten reply header build function. The old version
+ had several levels of hacks, was unmaintainable, did not follow
+ HTTP specification in details; fixed used caseless header matching
+ where case-sensitive matching must be used; removed two passes of
+ header building. New version use clear logic and can be extended
+ when needed.
+ Changed behaviour: "Connection: keep-alive" is not being sent
+ for HTTP/1.1 connection (as per HTTP RFC).
+ test_get_chunked: fixed error reporting.
+ HTTPS tests: fixed memory leaks if function failed.
+ libcurl tests: improved handling of curl multi_*.
+ Added two tests for correct choice of "Keep-Alive" or "Close".
+ Simplified Makefile for testcurl.
+ Fixed select() error handling in tests.
+ microhttpd.h: minor macro formatting
+ Changed behaviour: if response size is unknown and chunked encoding is
+ allowed, chunked encoding is used even for non-keep-alive connection as
+ required by HTTP RFC.
+ Added two more tests for chunked replies.
+ Simplified keepalive_possible(); added new value for MHD_ConnKeepAlive,
+ added third state "Upgrade".
+ Changed behaviour: used HTTP/1.1 replies for HTTP/1.0 requests as
+ required by HTTP RFC. HTTP/1.0 reply still can be enforced by response
+ flag.
+ Added more doxy for MHD_ResponseFlags, added new names with the same
+ values as old names: MHD_RF_HTTP_1_0_COMPATIBLE_STRICT and
+ MHD_RF_HTTP_1_0_SERVER.
+ Added new value MHD_RF_SEND_KEEP_ALIVE_HEADER to enforce sending of
+ "Connection: keep-alive" even for HTTP/1.1 clients when keep-alive is
+ used.

+ Some data races and other multithread-related issues are fixed,
+ including usage of closed sockets (may resulted in accidental closing
+ of wrong socket).
+ SO_NOSIGPIPE is used on all platform which support it, not only
+ on Darwin.
+ Added support for suspending connections in thread-per-connection

+ Fixed Inter-Thread Communication channel usage in epoll modes.
+ Reworked daemon cleanups and handling MHD_stop_daemon(): resources
+ are freed only by specific threads, data races and other fixes.

+ fallback to 'int'.
+ Renamed many MHD flags. Now they are self-explainable and more
+ obvious, like MHD_USE_INTERNAL_POLLING_THREAD instead of
+ MHD_USE_SELECT_INTERNALLY. Old flag names are supported for
+ backward compatibility.
+ Improved processing of "fast" connections: now full sequence
+ "read request - send reply headers - send reply body" is processed
+ after single select()/poll(). If connection is slow, request is huge
+ or response in not immediately ready - connection will be processed
+ in "traditional" way.

-
-Basic Installation
-==================
-
- Briefly, the shell command `./configure && make && make install'
-should configure, build, and install this package. The following
-more-detailed instructions are generic; see the `README' file for
-instructions specific to this package. Some packages provide this
-`INSTALL' file but do not implement all of the features documented
-below. The lack of an optional feature in a given package is not
-necessarily a bug. More recommendations for GNU packages can be found
-in *note Makefile Conventions: (standards)Makefile Conventions.
-
- The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation. It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions. Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, and a
-file `config.log' containing compiler output (useful mainly for
-debugging `configure').
-
- It can also use an optional file (typically called `config.cache'
-and enabled with `--cache-file=config.cache' or simply `-C') that saves
-the results of its tests to speed up reconfiguring. Caching is
-disabled by default to prevent problems with accidental use of stale
-cache files.
-
- If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release. If you are using the cache, and at
-some point `config.cache' contains results you don't want to keep, you
-may remove or edit it.
-
- The file `configure.ac' (or `configure.in') is used to create
-`configure' by a program called `autoconf'. You need `configure.ac' if
-you want to change it or regenerate `configure' using a newer version
-of `autoconf'.
-
- The simplest way to compile this package is:
-
- 1. `cd' to the directory containing the package's source code and type
- `./configure' to configure the package for your system.
-
- Running `configure' might take a while. While running, it prints
- some messages telling which features it is checking for.
-
- 2. Type `make' to compile the package.
-
- 3. Optionally, type `make check' to run any self-tests that come with
- the package, generally using the just-built uninstalled binaries.
-
- 4. Type `make install' to install the programs and any data files and
- documentation. When installing into a prefix owned by root, it is
- recommended that the package be configured and built as a regular
- user, and only the `make install' phase executed with root
- privileges.
-
- 5. Optionally, type `make installcheck' to repeat any self-tests, but
- this time using the binaries in their final installed location.
- This target does not install anything. Running this target as a
- regular user, particularly if the prior `make install' required
- root privileges, verifies that the installation completed
- correctly.
-
- 6. You can remove the program binaries and object files from the
- source code directory by typing `make clean'. To also remove the
- files that `configure' created (so you can compile the package for
- a different kind of computer), type `make distclean'. There is
- also a `make maintainer-clean' target, but that is intended mainly
- for the package's developers. If you use it, you may have to get
- all sorts of other programs in order to regenerate files that came
- with the distribution.
-
- 7. Often, you can also type `make uninstall' to remove the installed
- files again. In practice, not all packages have tested that
- uninstallation works correctly, even though it is required by the
- GNU Coding Standards.
-
- 8. Some packages, particularly those that use Automake, provide `make
- distcheck', which can by used by developers to test that all other
- targets like `make install' and `make uninstall' work correctly.
- This target is generally not run by end users.
-
-Compilers and Options
-=====================
-
- Some systems require unusual options for compilation or linking that
-the `configure' script does not know about. Run `./configure --help'
-for details on some of the pertinent environment variables.
-
- You can give `configure' initial values for configuration parameters
-by setting variables in the command line or in the environment. Here
-is an example:
-
- ./configure CC=c99 CFLAGS=-g LIBS=-lposix
-
- *Note Defining Variables::, for more details.
-
-Compiling For Multiple Architectures
-====================================
-
- You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory. To do this, you can use GNU `make'. `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script. `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'. This
-is known as a "VPATH" build.
-
- With a non-GNU `make', it is safer to compile the package for one
-architecture at a time in the source code directory. After you have
-installed the package for one architecture, use `make distclean' before
-reconfiguring for another architecture.
-
- On MacOS X 10.5 and later systems, you can create libraries and
-executables that work on multiple system types--known as "fat" or
-"universal" binaries--by specifying multiple `-arch' options to the
-compiler but only a single `-arch' option to the preprocessor. Like
-this:
-
- ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
- CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
- CPP="gcc -E" CXXCPP="g++ -E"
-
- This is not guaranteed to produce working output in all cases, you
-may have to build one architecture at a time and combine the results
-using the `lipo' tool if you have problems.
-
-Installation Names
-==================
-
- By default, `make install' installs the package's commands under
-`/usr/local/bin', include files under `/usr/local/include', etc. You
-can specify an installation prefix other than `/usr/local' by giving
-`configure' the option `--prefix=PREFIX', where PREFIX must be an
-absolute file name.
-
- You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files. If you
-pass the option `--exec-prefix=PREFIX' to `configure', the package uses
-PREFIX as the prefix for installing programs and libraries.
-Documentation and other data files still use the regular prefix.
-
- In addition, if you use an unusual directory layout you can give
-options like `--bindir=DIR' to specify different values for particular
-kinds of files. Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them. In general, the
-default for these options is expressed in terms of `${prefix}', so that
-specifying just `--prefix' will affect all of the other directory
-specifications that were not explicitly provided.
-
- The most portable way to affect installation locations is to pass the
-correct locations to `configure'; however, many packages provide one or
-both of the following shortcuts of passing variable assignments to the
-`make install' command line to change installation locations without
-having to reconfigure or recompile.
-
- The first method involves providing an override variable for each
-affected directory. For example, `make install
-prefix=/alternate/directory' will choose an alternate location for all
-directory configuration variables that were expressed in terms of
-`${prefix}'. Any directories that were specified during `configure',
-but not in terms of `${prefix}', must each be overridden at install
-time for the entire installation to be relocated. The approach of
-makefile variable overrides for each directory variable is required by
-the GNU Coding Standards, and ideally causes no recompilation.
-However, some platforms have known limitations with the semantics of
-shared libraries that end up requiring recompilation when using this
-method, particularly noticeable in packages that use GNU Libtool.
-
- The second method involves providing the `DESTDIR' variable. For
-example, `make install DESTDIR=/alternate/directory' will prepend
-`/alternate/directory' before all installation names. The approach of
-`DESTDIR' overrides is not required by the GNU Coding Standards, and
-does not work on platforms that have drive letters. On the other hand,
-it does better at avoiding recompilation issues, and works well even
-when some directory options were not specified in terms of `${prefix}'
-at `configure' time.
-
-Optional Features
-=================
-
- If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
- Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System). The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
- For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
- Some packages offer the ability to configure how verbose the
-execution of `make' will be. For these packages, running `./configure
---enable-silent-rules' sets the default to minimal output, which can be
-overridden with `make V=1'; while running `./configure
---disable-silent-rules' sets the default to verbose, which can be
-overridden with `make V=0'.
-
-Particular systems
-==================
-
- On HP-UX, the default C compiler is not ANSI C compatible. If GNU
-CC is not installed, it is recommended to use the following options in
-order to use an ANSI C compiler:
-
- ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
-
-and if that doesn't work, install pre-built binaries of GCC for HP-UX.
-
- HP-UX `make' updates targets which have the same time stamps as
-their prerequisites, which makes it generally unusable when shipped
-generated files such as `configure' are involved. Use GNU `make'
-instead.
-
- On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
-parse its `<wchar.h>' header file. The option `-nodtk' can be used as
-a workaround. If GNU CC is not installed, it is therefore recommended
-to try
-
- ./configure CC="cc"
-
-and if that doesn't work, try
-
- ./configure CC="cc -nodtk"
-
- On Solaris, don't put `/usr/ucb' early in your `PATH'. This
-directory contains several dysfunctional programs; working variants of
-these programs are available in `/usr/bin'. So, if you need `/usr/ucb'
-in your `PATH', put it _after_ `/usr/bin'.
-
- On Haiku, software installed for all users goes in `/boot/common',
-not `/usr/local'. It is recommended to use the following options:
-
- ./configure --prefix=/boot/common
-
-Specifying the System Type
-==========================
-
- There may be some features `configure' cannot figure out
-automatically, but needs to determine by the type of machine the package
-will run on. Usually, assuming the package is built to be run on the
-_same_ architectures, `configure' can figure that out, but if it prints
-a message saying it cannot guess the machine type, give it the
-`--build=TYPE' option. TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name which has the form:
-
- CPU-COMPANY-SYSTEM
-
-where SYSTEM can have one of these forms:
-
- OS
- KERNEL-OS
-
- See the file `config.sub' for the possible values of each field. If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the machine type.
-
- If you are _building_ compiler tools for cross-compiling, you should
-use the option `--target=TYPE' to select the type of system they will
-produce code for.
-
- If you want to _use_ a cross compiler, that generates code for a
-platform different from the build platform, you should specify the
-"host" platform (i.e., that on which the generated programs will
-eventually be run) with `--host=TYPE'.
-
-Sharing Defaults
-================
-
- If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists. Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Defining Variables
-==================
-
- Variables not defined in a site shell script can be set in the
-environment passed to `configure'. However, some packages may run
-configure again during the build, and the customized values of these
-variables may be lost. In order to avoid this problem, you should set
-them in the `configure' command line, using `VAR=value'. For example:
-
- ./configure CC=/usr/local2/bin/gcc
-
-causes the specified `gcc' to be used as the C compiler (unless it is
-overridden in the site shell script).
-
-Unfortunately, this technique does not work for `CONFIG_SHELL' due to
-an Autoconf limitation. Until the limitation is lifted, you can use
-this workaround:
-
- CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
-
-`configure' Invocation
-======================
-
- `configure' recognizes the following options to control how it
-operates.
-
-`--help'
-`-h'
- Print a summary of all of the options to `configure', and exit.
-
-`--help=short'
-`--help=recursive'
- Print a summary of the options unique to this package's
- `configure', and exit. The `short' variant lists options used
- only in the top level, while the `recursive' variant lists options
- also present in any nested packages.
-
-`--version'
-`-V'
- Print the version of Autoconf used to generate the `configure'
- script, and exit.
-
-`--cache-file=FILE'
- Enable the cache: use and save the results of the tests in FILE,
- traditionally `config.cache'. FILE defaults to `/dev/null' to
- disable caching.
-
-`--config-cache'
-`-C'
- Alias for `--cache-file=config.cache'.
-
-`--quiet'
-`--silent'
-`-q'
- Do not print messages saying which checks are being made. To
- suppress all normal output, redirect it to `/dev/null' (any error
- messages will still be shown).
-
-`--srcdir=DIR'
- Look for the package's source code in directory DIR. Usually
- `configure' can determine that directory automatically.
-
-`--prefix=DIR'
- Use DIR as the installation prefix. *note Installation Names::
- for more details, including other options available for fine-tuning
- the installation locations.
-
-`--no-create'
-`-n'
- Run the configure checks, but stop before creating any output
- files.
-
-`configure' also accepts some other, not widely useful, options. Run
-`configure --help' for more details.

+Released GNU libmicrohttpd 0.9.76 hotfix. -CG
+
+ This is a hotfix release.
+ This only change since previous release is fixed potential DoS vector
+ in MHD_PostProcessor discovered by Gynvael Coldwind and Dejan
+ Alvadzijevic (CVE-2023-27371).
+ While the researchers have not been able to exploit this attack vector
+ when libmicrohttpd is compiled with the standard GNU C library, it is
+ recommended that you update MHD as soon as possible if your
+ applications are using (optional) MHD_PostProcessor functionality.
+
+ -- Evgeny Grin (Karlson2k)
+
+Sun 26 Dec 2021 20:30:00 MSK
+Released GNU libmicrohttpd 0.9.75 -EG
+
+ This is a correction release.
+ The main improvement is the implementation of workaround for some
+ OSes (like OpenBSD 7) where "monotonic" clock may jump back. Now
+ MHD is able to automatically detect such situation and recover if
+ the jump is small. This workaround is needed with increased
+ accuracy of connection timeout introduced in previous version, as
+ with lower accuracy (v0.9.73 and before) these jumpbacks were
+ unnoticeable.
+ Other changes: fixed some compiler, Makefile, and configure
+ warnings on specific platforms; one test further improved.
+
+ -- Evgeny Grin (Karlson2k)
+
+
+Sun 19 Dec 2021 18:30:00 MSK
+Released GNU libmicrohttpd 0.9.74
+
+ This release brings a lot of fixes and improvements, and
+ important new features.
+ The most significant addition is the new experimental
+ implementation of WebSockets contributed by David Gausmann. This
+ implementation is not fully tested yet so currently it is disabled
+ by default.
+ Other changes include a lot of improvements and clarifications
+ in doxy comments in microhttpd.h header file, improved compliance
+ with the RFC HTTP specifications, the new implementation of reply
+ header forming, the new implementation of request chunked encoding
+ parsing, new automatic error replies, internal optimisations, and
+ many important fixes, including fixes for long-standing bugs.
+
+ More detailed list of notable changes:
+
+ API changes:
+ + Added new function MHD_get_reason_phrase_len_for().
+ + Added MHD_CONNECTION_INFO_HTTP_STATUS type of information
+ queried by MHD_get_connection_info().
+ + Added new response flag MHD_RF_SEND_KEEP_ALIVE_HEADER to force
+ sending of "keep-alive" header even if not required by RFC.
+ + Added new response creation function
+ MHD_create_response_from_buffer_with_free_callback_cls() with
+ custom cleanup callback.
+ + Added new response flag MHD_RF_HTTP_1_0_COMPATIBLE_STRICT with
+ the same functionality as existing MHD_RF_HTTP_VERSION_1_0_ONLY
+ flag. The old flag will be deprecated.
+ + Added new response flag MHD_RF_HTTP_1_0_SERVER with the same
+ functionality as existing MHD_RF_HTTP_VERSION_1_0_RESPONSE flag.
+ The old flag will be deprecated.
+
+ New features:
+ + Added experimental WebSockets extension with separate header.
+ Disabled by default as it is not fully tested yet.
+ + Added '--enable-sanitizers[=address,undefined,leak,user-poison]'
+ configure parameter (instead of '--enable-sanitizer'),
+ implemented custom memory poisoning for memory pools.
+
+ Improvements and enhancements:
+ * Doxy function descriptions was corrected, clarified, extended,
+ and improved. Now it should be much easier to learn MHD just by
+ reading the headers.
+ * Completely rewritten reply header forming. New implementation is
+ more robust, simpler maintainable and expandable, and better
+ follows RFC HTTP specifications.
+ * Performance improvements: now HTTP version and request method are
+ decoded one time only (previously MHD used string comparison many
+ times during processing the data).
+ * Rewritten request chunked payload decoding. The new
+ implementation better conforms to the HTTP RFC, detects format
+ problems earlier, replies to the clients with description of
+ detected problems, handles untypical (but syntactically correct)
+ values properly.
+ * Added special replies for wrong/unsupported HTTP versions in
+ requests, broken HTTP chunked encoding in requests,
+ * As required by HTTP RFC, added automatic error replies if client
+ used broken chunked encoding, too large chunk size, too large
+ payload size, or broken Content-Length header.
+ * Optimized connection's memory pool handling.
+ * Changed timeout precision from one second to one millisecond.
+ * Added some checks for incorrect user data, reporting problems in
+ MHD log.
+ * Improved performance of hash calculations functions by using
+ compiler built-ins (if available).
+ * Implemented SHA-1 calculations (required for WebSockets).
+ * Added universal MSVC project that works with any (sufficiently
+ new) version of MSVC.
+ * Developed simple HTTP client to test MHD under very special
+ conditions.
+ * Implemented 45 new tests.
+ * Improved existing tests to test more aspects of MHD.
+ * Added check for correct results of system and libcurl functions.
+ * Response headers are checked during forming of responses.
+ * HTTPS tests were improved.
+ * Added rebuild on W32 of all required files if files are missing.
+ * Many internal optimisations and improvements.
+
+ Functionality changes:
+ * Keep-alive header is omitted by default for HTTP/1.1 connections.
+ Use of header can be enforced by response flag.
+ * Chunked encoding is used for HTTP/1.1 non-keep-alive connections
+ for responses with unknown size. Previously MHD used "indication
+ of the end of the response by closing connection" in such cases,
+ however it is not correct for HTTP/1.1 connections as per HTTP
+ RFC.
+ * As required by HTTP RFC, use HTTP/1.1 version instead of HTTP/1.0
+ in reply headers when client is HTTP/1.0 . HTTP/1.0 version can
+ be enforced by response flag.
+ * User response headers are used in replies in the same order as
+ was added by application.
+ * Allowed tab characters in response header values.
+ * All custom "Connection:" response headers are automatically
+ combined into single "Connection:" header.
+ * "keep-alive" token silently dropped from custom "Connection:"
+ response header. "Keep-alive" cannot be enforced and used
+ automatically if possible.
+ * Allow tab character in custom response header value.
+ * Disallow space character in custom response header value.
+ * Do not allow responses with 1xx codes for HTTP/1.0 requests.
+ * Detected and reported incorrect "Upgrade" responses.
+ * W32 targets are changed to Vista+ by default. XP is supported
+ still.
+
+ Fixes:
+ # Fixed short busy-waiting (up to one second) when connection is
+ going to be expired and closed.
+ # Fixed handling of errors during start of new connection, fixed
+ inability to accept new connections in thread-per-connection mode
+ due to the missing decrement of number of daemon's connections if
+ start of new thread is failed.
+ # Fixed incorrect parsing of LFLF, LFCR, CRCR, and bare CR as
+ single linefeed in request header and request chunked payload.
+ Now only CRLF or bare LF are recognized as linefeed.
+ # Fixed response chunked encoding handling. Now it works properly
+ with non-keep-alive connection, with fixed size replies (if
+ chunked was enforced by header), and in other situations.
+ # Other fixes for chunked replies.
+ # Fixed handling of custom connection timeout in thread-per-
+ connection mode.
+ # Fixed wrongly used MHD_REQUEST_TERMINATED_COMPLETED_OK code for
+ application notification when MHD_REQUEST_TERMINATED_WITH_ERROR
+ code must be used.
+ # Fixed code MHD_REQUEST_TERMINATED_READ_ERROR not reported (code
+ MHD_REQUEST_TERMINATED_WITH_ERROR was incorrectly used instead).
+ # Fixed handling of request chunked encoding with untypical
+ formatting.
+ # Fixed processing of last part of hex-encoded values under
+ certain conditions.
+ # Fixed value returned for MHD_CONNECTION_INFO_REQUEST_HEADER_SIZE.
+ # Fixed returned value for MHD_FEATURE_AUTOSUPPRESS_SIGPIPE on W32,
+ now it is MHD_YES as W32 does not need SIGPIPE suppression.
+ # Fixed portability of bitwise NOT for enums values.
+ # Fixed SHA-256 and MD5 calculations with unaligned data.
+ # Fixed incorrect caseless matching for HTTP version.
+ # Fixed incorrect caseless matching for request method.
+ # Fixed compatibility with old GnuTLS versions.
+ # Fixed compiler warnings on 32-bits platforms.
+ # Fixed blocking sockets setting in tests and examples for W32.
+ # Fixed examples to really use libmagic if present.
+ # HTTPS tests were fixed.
+ # Fixed libcurl test with case-insensitive match for HTTP methods,
+ method names must use case-sensitive match.
+ # Fixed tests compatibility with old libcurl versions.
+ # Fixed build on W32 with llvm-dlltool (this tool is too
+ oversimplified)

+ patch provided by Lawrence Sebald and Damon N. Earp from NASA.
+ + Added MHD_OPTION_SIGPIPE_HANDLED_BY_APP daemon option.
+ + Added new function MHD_run_wait().
+ + Added MHD_OPTION_TLS_NO_ALPN to disable usage of ALPN even if
+ it is supported by TLS library.
+
+ New features:
+ + Added '--enable-heavy-tests' configure parameter (disabled by
+ default).
+ + Implemented support for ALPN.
+
+ Improvements and enhancements:
+ * Return timeout of zero also for connections awaiting cleanup.
+ * Compatibility with autoconf >=2.70, used new autoconf features.
+ * Warn user when custom logger option is not the first option.
+ * Added information to the header about minimal MHD version when
+ particular symbols were introduced.
+ * Updated test certificates to be compatible with modern browsers.
+ * Added on-fly detection of UNIX domain sockets and pipes, MHD does
+ not try to use TCP/IP-specific socket options on them.
+ * Report more detailed error description in the MHD log for send
+ and receive errors.
+ * Enabled bind port autodetection for MSVC builds.
+
+ Fixes:
+ # Fix PostProcessor to always properly stop iteration when
+ application callback tells it to do so.
+ # Fixed MD5 digest authorization broken when compiled without
+ variable length arrays support (notably with MSVC).
+ # Fixed detection of type of send errors on W32.

+Released GNU libmicrohttpd 0.9.72
+
+ This release is mostly a bugfix release, with greatly improved
+ compatibility with various OSes/kernels, including FreeBSD, Windows,
+ OpenBSD, NetBSD, Darwin (macOS), Solaris. Performance is improved,
+ especially with HTTPS connections and stay-alive HTTP connections.
+
+ Notable changes since version 0.9.71:
+
+ API changes:
+ + New function MHD_create_response_from_pipe()
+
+ Improvements and enhancements:
+ * Fully rewritten code for buffering/pushing from kernel network buffers
+ for compatibility with various OSes. Reduced number of additional
+ sys-calls, network is better utilized, responses are delivered faster.
+ * Restored optimal sendfile() usage on FreeBSD.
+ * MHD now takes care about SIGPIPE handling by blocking it in internal
+ threads and avoiding functions (like sendfile()) that could generate
+ SIGPIPE when blocking of this signal is not possible.
+
+ Fixes:
+ # Fixed crash in PostProcessor.
+ # Fixed several resources leaks in corner cases.
+ # Improved thread sync, thread safety and fixed one use-after-free under
+ special conditions during stopping of daemon.
+ # Updated HTTP status codes, header names and methods from the
+ registries.
+ # Fixed functioning without listen socket and with internal threads.
+ # Fixed streaming of chunked responses for both HTTP and HTTPS.
+ # Various compatibility fixes.

-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir. In an in-source build this is usually
-# harmless because $srcdir is '.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.

-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.

-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE. See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
- -h, --help display this help and exit
- --help=short display options specific to this package
- --help=recursive display the short help of all the included packages
- -V, --version display version information and exit
- -q, --quiet, --silent do not print \`checking ...' messages
- --cache-file=FILE cache test results in FILE [disabled]
- -C, --config-cache alias for \`--cache-file=config.cache'
- -n, --no-create do not create output files
- --srcdir=DIR find the sources in DIR [configure dir or \`..']
-
-Installation directories:
- --prefix=PREFIX install architecture-independent files in PREFIX
- [$ac_default_prefix]
- --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
- [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:
- --bindir=DIR user executables [EPREFIX/bin]
- --sbindir=DIR system admin executables [EPREFIX/sbin]
- --libexecdir=DIR program executables [EPREFIX/libexec]
- --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
- --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
- --localstatedir=DIR modifiable single-machine data [PREFIX/var]
- --libdir=DIR object code libraries [EPREFIX/lib]
- --includedir=DIR C header files [PREFIX/include]
- --oldincludedir=DIR C header files for non-gcc [/usr/include]
- --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
- --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
- --infodir=DIR info documentation [DATAROOTDIR/info]
- --localedir=DIR locale-dependent data [DATAROOTDIR/locale]
- --mandir=DIR man documentation [DATAROOTDIR/man]
- --docdir=DIR documentation root [DATAROOTDIR/doc/libmicrohttpd]
- --htmldir=DIR html documentation [DOCDIR]
- --dvidir=DIR dvi documentation [DOCDIR]
- --pdfdir=DIR pdf documentation [DOCDIR]
- --psdir=DIR ps documentation [DOCDIR]

- --with-gnutls[=PFX] use GnuTLS for HTTPS support, optional PFX overrides
- pkg-config data for GnuTLS headers (PFX/include) and
- libs (PFX/lib)
-
-Some influential environment variables:
- CC C compiler command
- CFLAGS C compiler flags
- LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
- nonstandard directory <lib dir>
- LIBS libraries to pass to the linker, e.g. -l<library>
- CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
- you have headers in a nonstandard directory <include dir>
- CPP C preprocessor
- PKG_CONFIG path to pkg-config utility
- PKG_CONFIG_PATH
- directories to add to pkg-config's search path
- PKG_CONFIG_LIBDIR
- path overriding pkg-config's built-in search path
- GNUTLS_CFLAGS
- C compiler flags for GNUTLS, overriding pkg-config
- GNUTLS_LIBS linker flags for GNUTLS, overriding pkg-config
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.
-
-Report bugs to <libmicrohttpd@gnu.org>.

+Subject: [PATCH 1/2] Pick up clang_rt static archives compiler internal
+ libraries
+
+Libtool checks only for libraries linked as -l* when trying to
+find internal compiler libraries. Clang, however uses the absolute
+path to link its internal libraries e.g. compiler_rt. This patch
+handles clang's statically linked libraries when finding internal
+compiler libraries.

+Subject: [PATCH 2/2] Prefer response files over linker scripts for mingw tools
+
+The GCC/binutils tools support response files just fine, while
+lld (impersonating GNU ld) only supports response files, not
+linker scripts. Using a linker script as input just to pass a
+list of files is overkill for cases when a response file is enough.

-## - Don't want to use -MD because we'd like the dependencies to end
-## up in a subdir. Having to rename by hand is ugly.
-## (We might end up doing this anyway to support other compilers.)
-## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
-## -MM, not -M (despite what the docs say). Also, it might not be
-## supported by the other compilers which use the 'gcc' depmode.
-## - Using -M directly means running the compiler twice (even worse
-## than renaming).

-## This next piece of magic avoids the "deleted header file" problem.
-## The problem is that when a header file which appears in a .P file
-## is deleted, the dependency causes make to die (because there is
-## typically no way to rebuild the header). We avoid this by adding
-## dummy dependencies for each header file. Too bad gcc doesn't do
-## this for us directly.
-## Some versions of gcc put a space before the ':'. On the theory
-## that the space means something, we add a space to the output as
-## well. hp depmode also adds that space, but also prefixes the VPATH
-## to the object. Take care to not repeat it in the output.

+Before we will start implementing @emph{Basic Authentication} as described in
+@emph{RFC 2617}, we will also abandon the simplistic and generally
+problematic practice of responding every request the first time our callback
+is called for a given connection. Queuing a response upon the first request
+is akin to generating an error response (even if it is a "200 OK" reply!).
+The reason is that MHD usually calls the callback in three phases:
-But how can we tell whether the callback has been called before for the particular connection?
-Initially, the pointer this parameter references is set by @emph{MHD} in the callback. But it will
-also be "remembered" on the next call (for the same connection).
-Thus, we will generate no response until the parameter is non-null---implying the callback was
-called before at least once. We do not need to share information between different calls of the callback,
-so we can set the parameter to any adress that is assured to be not null. The pointer to the
-@code{connection} structure will be pointing to a legal address, so we take this.
+@enumerate
+@item
+First, to initially tell the application about the connection and inquire whether
+it is OK to proceed. This call typically happens before the client could upload
+the request body, and can be used to tell the client to not proceed with the
+upload (if the client requested "Expect: 100 Continue"). Applications may queue
+a reply at this point, but it will force the connection to be closed and thus
+prevent keep-alive / pipelining, which is generally a bad idea. Applications
+wanting to proceed with the request throughout the other phases should just return
+"MHD_YES" and not queue any response. Note that when an application suspends
+a connection in this callback, the phase does not advance and the application
+will be called again in this first phase.
+@item
+Next, to tell the application about upload data provided by the client.
+In this phase, the application may not queue replies, and trying to do so
+will result in MHD returning an error code from @code{MHD_queue_response}.
+If there is no upload data, this phase is skipped.
+@item
+Finally, to obtain a regular response from the application. This can be
+almost any type of response, including ones indicating failures. The
+one exception is a "100 Continue" response, which applications must never
+generate: MHD generates that response automatically when necessary in the
+first phase. If the application does not queue a response, MHD may call
+the callback repeatedly (depending a bit on the threading model, the
+application should suspend the connection).
+@end enumerate
+
+But how can we tell whether the callback has been called before for the
+particular request? Initially, the pointer this parameter references is
+set by @emph{MHD} in the callback. But it will also be "remembered" on the
+next call (for the same request). Thus, we can use the @code{req_cls}
+location to keep track of the request state. For now, we will simply
+generate no response until the parameter is non-null---implying the callback
+was called before at least once. We do not need to share information between
+different calls of the callback, so we can set the parameter to any address
+that is assured to be not null. The pointer to the @code{connection} structure

+Websockets are a genuine way to implement push notifications,
+where the server initiates the communication while the client can be idle.
+Usually a HTTP communication is half-duplex and always requested by the client,
+but websockets are full-duplex and only initialized by the client.
+In the further communication both sites can use the websocket at any time
+to send data to the other site.
+
+To initialize a websocket connection the client sends a special HTTP request
+to the server and initializes
+a handshake between client and server which switches from the HTTP protocol
+to the websocket protocol.
+Thus both the server as well as the client must support websockets.
+If proxys are used, they must support websockets too.
+In this chapter we take a look on server and client, but with a focus on
+the server with @emph{libmicrohttpd}.
+
+Since version 0.9.52 @emph{libmicrohttpd} supports upgrading requests,
+which is required for switching from the HTTP protocol.
+Since version 0.9.74 the library @emph{libmicrohttpd_ws} has been added
+to support the websocket protocol.
+
+@heading Upgrading connections with libmicrohttpd
+
+To support websockets we need to enable upgrading of HTTP connections first.
+This is done by passing the flag @code{MHD_ALLOW_UPGRADE} to
+@code{MHD_start_daemon()}.

+An @code{upgrade_handler} will be passed to perform the low-level actions
+on the socket.
+
+@emph{Please note that the socket here is just a regular socket as provided
+by the operating system.
+To use it as a websocket, some more steps from the following
+chapters are required.}

+In the @code{upgrade_handler} we receive the low-level socket,
+which is used for the communication with the specific client.
+In addition to the low-level socket we get:
+@itemize @bullet
+@item
+Some data, which has been read too much while @emph{libmicrohttpd} was
+switching the protocols.
+This value is usually empty, because it would mean that the client
+has sent data before the handshake was complete.
+
+@item
+A @code{struct MHD_UpgradeResponseHandle} which is used to perform
+special actions like closing, corking or uncorking the socket.
+These commands are executed by passing the handle
+to @code{MHD_upgrade_action()}.
+
+
+@end itemize
+
+Depending of the flags specified while calling @code{MHD_start_deamon()}
+our @code{upgrade_handler} is either executed in the same thread
+as our daemon or in a thread specific for each connection.
+If it is executed in the same thread then @code{upgrade_handler} is
+a blocking call for our webserver and
+we should finish it as fast as possible (i. e. by creating a thread and
+passing the information there).
+If @code{MHD_USE_THREAD_PER_CONNECTION} was passed to
+@code{MHD_start_daemon()} then a separate thread is used and
+thus our @code{upgrade_handler} needs not to start a separate thread.
+
+An @code{upgrade_handler}, which is called with a separate thread
+per connection, could look like this:
+

+ /* close the socket when it is not needed anymore */
+ MHD_upgrade_action (urh,
+ MHD_UPGRADE_ACTION_CLOSE);
+}
+@end verbatim
+@noindent

+
+This is all you need to know for upgrading connections

+The next chapters focus on using the websocket protocol
+with @emph{libmicrohttpd_ws}.
+
+
+@heading Websocket handshake with libmicrohttpd_ws
+

+@item
+A @code{GET} request must be sent.
+
+@item
+The version of the HTTP protocol must be 1.1 or higher.

+Please note that the client could pass multiple protocols separated by comma.
+
+@item
+A @code{Connection} header field that includes the token "Upgrade"
+(case-insensitive).
+Please note that the client could pass multiple tokens separated by comma.
+
+@item
+A @code{Sec-WebSocket-Key} header field with a base64-encoded value.
+The decoded the value is 16 bytes long
+and has been generated randomly by the client.
+
+@item
+A @code{Sec-WebSocket-Version} header field with the value "13".
+
+@end itemize

+
+Optionally the client can also send the following information:
+
+
+@itemize @bullet
+@item
+A @code{Origin} header field can be used to determine the source
+of the client (i. e. the website).
+
+@item
+A @code{Sec-WebSocket-Protocol} header field can contain a list
+of supported protocols by the client, which can be sent over the websocket.
+
+@item
+A @code{Sec-WebSocket-Extensions} header field which may contain extensions
+to the websocket protocol. The extensions must be registered by IANA.

+Sec-WebSocket-Key: dGhlIHNhbXBsZSBub25jZQ==
+Sec-WebSocket-Version: 13
+@end verbatim
+@noindent
+
+
+To complete the handshake the server must respond with
+some specific response headers:
+
+@itemize @bullet
+@item
+The HTTP response code @code{101 Switching Protocols} must be answered.
+
+@item
+An @code{Upgrade} header field containing the value "websocket" must be sent.
+
+@item
+A @code{Connection} header field containing the value "Upgrade" must be sent.
+
+@item
+A @code{Sec-WebSocket-Accept} header field containing a value, which
+has been calculated from the @code{Sec-WebSocket-Key} request header field,
+must be sent.
+
+@end itemize
+
+
+Optionally the server may send following headers:
+
+
+@itemize @bullet
+@item
+A @code{Sec-WebSocket-Protocol} header field containing a protocol
+of the list specified in the corresponding request header field.
+
+@item
+A @code{Sec-WebSocket-Extension} header field containing all used extensions
+of the list specified in the corresponding request header field.
+
+@end itemize

+A valid websocket HTTP response could look like this:

+
+
+To upgrade a connection to a websocket the @emph{libmicrohttpd_ws} provides
+some helper functions for the @code{access_handler} callback function:
+
+@itemize @bullet
+@item
+@code{MHD_websocket_check_http_version()} checks whether the HTTP version
+is 1.1 or above.
+
+@item
+@code{MHD_websocket_check_connection_header()} checks whether the value
+of the @code{Connection} request header field contains
+an "Upgrade" token (case-insensitive).
+
+@item
+@code{MHD_websocket_check_upgrade_header()} checks whether the value
+of the @code{Upgrade} request header field contains
+the "websocket" keyword (case-insensitive).
+
+@item
+@code{MHD_websocket_check_version_header()} checks whether the value
+of the @code{Sec-WebSocket-Version} request header field is "13".
+
+@item
+@code{MHD_websocket_create_accept_header()} takes the value from
+the @code{Sec-WebSocket-Key} request header and calculates the value
+for the @code{Sec-WebSocket-Accept} response header field.

+
+@heading Decoding/encoding the websocket protocol with libmicrohttpd_ws
+
+Once the websocket connection is established you can receive/send frame data
+with the low-level socket functions @code{recv()} and @code{send()}.
+The frame data which goes over the low-level socket is encoded according
+to the websocket protocol.
+To use received payload data, you need to decode the frame data first.
+To send payload data, you need to encode it into frame data first.
+
+@emph{libmicrohttpd_ws} provides several functions for encoding of
+payload data and decoding of frame data:
+
+@itemize @bullet
+@item
+@code{MHD_websocket_decode()} decodes received frame data.
+The payload data may be of any kind, depending upon what the client has sent.
+So this decode function is used for all kind of frames and returns
+the frame type along with the payload data.
+
+@item
+@code{MHD_websocket_encode_text()} encodes text.
+The text must be encoded with UTF-8.
+
+@item
+@code{MHD_websocket_encode_binary()} encodes binary data.
+
+@item
+@code{MHD_websocket_encode_ping()} encodes a ping request to
+check whether the websocket is still valid and to test latency.
+
+@item
+@code{MHD_websocket_encode_ping()} encodes a pong response to
+answer a received ping request.
+
+@item
+@code{MHD_websocket_encode_close()} encodes a close request.
+
+@item
+@code{MHD_websocket_free()} frees data returned by the encode/decode functions.
+
+@end itemize
+
+Since you could receive or send fragmented data (i. e. due to a too
+small buffer passed to @code{recv}) all of these encode/decode
+functions require a pointer to a @code{struct MHD_WebSocketStream} passed
+as argument.
+In this structure @emph{libmicrohttpd_ws} stores information
+about encoding/decoding of the particular websocket.
+For each websocket you need a unique @code{struct MHD_WebSocketStream}
+to encode/decode with this library.
+
+To create or destroy @code{struct MHD_WebSocketStream}
+we have additional functions:
+
+@itemize @bullet
+@item
+@code{MHD_websocket_stream_init()} allocates and initializes
+a new @code{struct MHD_WebSocketStream}.
+You can specify some options here to alter the behavior of the websocket stream.
+
+@item
+@code{MHD_websocket_stream_free()} frees a previously allocated
+@code{struct MHD_WebSocketStream}.
+
+@end itemize
+
+With these encode/decode functions we can improve our @code{upgrade_handler}
+callback function from an earlier example to a working websocket:

+@noindent
+
+
+Please note that the websocket in this example is only half-duplex.
+It waits until the blocking @code{recv()} call returns and
+only does then something.
+In this example all frame types are decoded by @emph{libmicrohttpd_ws},
+but we only do something when a text, ping or close frame is received.
+Binary and pong frames are ignored in our code.
+This is legit, because the server is only required to implement at
+least support for ping frame or close frame (the other frame types
+could be skipped in theory, because they don't require an answer).
+The pong frame doesn't require an answer and whether text frames or
+binary frames get an answer simply belongs to your server application.
+So this is a valid minimal example.
+
+Until this point you've learned everything you need to basically
+use websockets with @emph{libmicrohttpd} and @emph{libmicrohttpd_ws}.
+These libraries offer much more functions for some specific cases.
+
+
+The further chapters of this tutorial focus on some specific problems
+and the client site programming.
+
+
+@heading Using full-duplex websockets
+
+To use full-duplex websockets you can simply create two threads
+per websocket connection.
+One of these threads is used for receiving data with
+a blocking @code{recv()} call and the other thread is triggered
+by the application internal codes and sends the data.
+
+A full-duplex websocket example is implemented in the example file
+@code{websocket_chatserver_example.c}.
+
+@heading Error handling
+
+The most functions of @emph{libmicrohttpd_ws} return a value
+of @code{enum MHD_WEBSOCKET_STATUS}.
+The values of this enumeration can be converted into an integer
+and have an easy interpretation:
+
+@itemize @bullet
+@item
+If the value is less than zero an error occurred and the call has failed.
+Check the enumeration values for more specific information.
+
+@item
+If the value is equal to zero, the call succeeded.
+
+@item
+If the value is greater than zero, the call succeeded and the value
+specifies the decoded frame type.
+Currently positive values are only returned by @code{MHD_websocket_decode()}
+(of the functions with this return enumeration type).
+
+@end itemize
+
+A websocket stream can also get broken when invalid frame data is received.
+Also the other site could send a close frame which puts the stream into
+a state where it may not be used for regular communication.
+Whether a stream has become broken, can be checked with
+@code{MHD_websocket_stream_is_valid()}.
+
+
+@heading Fragmentation
+
+In addition to the regular TCP/IP fragmentation the websocket protocol also
+supports fragmentation.
+Fragmentation could be used for continuous payload data such as video data
+from a webcam.
+Whether or not you want to receive fragmentation is specified upon
+initialization of the websocket stream.
+If you pass @code{MHD_WEBSOCKET_FLAG_WANT_FRAGMENTS} in the flags parameter
+of @code{MHD_websocket_stream_init()} then you can receive fragments.
+If you don't pass this flag (in the most cases you just pass zero as flags)
+then you don't want to handle fragments on your own.
+@emph{libmicrohttpd_ws} removes then the fragmentation for you
+in the background.
+You only get the completely assembled frames.
+
+Upon encoding you specify whether or not you want to create a fragmented frame
+by passing a flag to the corresponding encode function.
+Only @code{MHD_websocket_encode_text()} and @code{MHD_websocket_encode_binary()}
+can be used for fragmentation, because the other frame types may
+not be fragmented.
+Encoding fragmented frames is independent of
+the @code{MHD_WEBSOCKET_FLAG_WANT_FRAGMENTS} flag upon initialization.
+
+@heading Quick guide to websockets in JavaScript
+
+Websockets are supported in all modern web browsers.
+You initialize a websocket connection by creating an instance of
+the @code{WebSocket} class provided by the web browser.
+
+There are some simple rules for using websockets in the browser:
+
+@itemize @bullet
+@item
+When you initialize the instance of the websocket class you must pass an URL.
+The URL must either start with @code{ws://}
+(for not encrypted websocket protocol) or @code{wss://}
+(for TLS-encrypted websocket protocol).
+
+@strong{IMPORTANT:} If your website is accessed via @code{https://}
+then you are in a security context, which means that you are only allowed to
+access other secure protocols.
+So you can only use @code{wss://} for websocket connections then.
+If you try to @code{ws://} instead then your websocket connection will
+automatically fail.
+
+@item
+The WebSocket class uses events to handle the receiving of data.
+JavaScript is per definition a single-threaded language so
+the receiving events will never overlap.
+Sending is done directly by calling a method of the instance of
+the WebSocket class.
+
+@end itemize
+
+
+Here is a short example for receiving/sending data to the same host
+as the website is running on:
+
+@verbatim
+<!DOCTYPE html>
+<html>
+<head>
+<meta charset="UTF-8">
+<title>Websocket Demo</title>
+<script>
+
+let url = 'ws' + (window.location.protocol === 'https:' ? 's' : '') + '://' +
+ window.location.host + '/chat';
+let socket = null;
+
+window.onload = function(event) {
+ socket = new WebSocket(url);
+ socket.onopen = function(event) {
+ document.write('The websocket connection has been established.<br>');
+
+ // Send some text
+ socket.send('Hello from JavaScript!');
+ }
+
+ socket.onclose = function(event) {
+ document.write('The websocket connection has been closed.<br>');
+ }
+
+ socket.onerror = function(event) {
+ document.write('An error occurred during the websocket communication.<br>');
+ }
+
+ socket.onmessage = function(event) {
+ document.write('Websocket message received: ' + event.data + '<br>');
+ }
+}
+
+</script>

-@subheading Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software---to make sure the software is free for all its users. This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it. (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.) You can apply it to
-your programs, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have. You must make sure that they, too, receive or can get the
-source code. And you must show them these terms so they know their
-rights.
-
- We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
- Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software. If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
- Finally, any free program is threatened constantly by software
-patents. We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary. To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
- The precise terms and conditions for copying, distribution and
-modification follow.

-@subheading TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-@end iftex
-@ifinfo
-@center TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-@end ifinfo
-
-@enumerate
-@item
-This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License. The ``Program'', below,
-refers to any such program or work, and a ``work based on the Program''
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language. (Hereinafter, translation is included without limitation in
-the term ``modification''.) Each licensee is addressed as ``you''.
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-@item
-You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-@item
-You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-@enumerate a
-@item
-You must cause the modified files to carry prominent notices
-stating that you changed the files and the date of any change.
-
-@item
-You must cause any work that you distribute or publish, that in
-whole or in part contains or is derived from the Program or any
-part thereof, to be licensed as a whole at no charge to all third
-parties under the terms of this License.
-
-@item
-If the modified program normally reads commands interactively
-when run, you must cause it, when started running for such
-interactive use in the most ordinary way, to print or display an
-announcement including an appropriate copyright notice and a
-notice that there is no warranty (or else, saying that you provide
-a warranty) and that users may redistribute the program under
-these conditions, and telling the user how to view a copy of this
-License. (Exception: if the Program itself is interactive but
-does not normally print such an announcement, your work based on
-the Program is not required to print an announcement.)
-@end enumerate
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-@item
-You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-@enumerate a
-@item
-Accompany it with the complete corresponding machine-readable
-source code, which must be distributed under the terms of Sections
-1 and 2 above on a medium customarily used for software interchange; or,
-
-@item
-Accompany it with a written offer, valid for at least three
-years, to give any third party, for a charge no more than your
-cost of physically performing source distribution, a complete
-machine-readable copy of the corresponding source code, to be
-distributed under the terms of Sections 1 and 2 above on a medium
-customarily used for software interchange; or,
-
-@item
-Accompany it with the information you received as to the offer
-to distribute corresponding source code. (This alternative is
-allowed only for noncommercial distribution and only if you
-received the program in object code or executable form with such
-an offer, in accord with Subsection b above.)
-@end enumerate
-
-The source code for a work means the preferred form of the work for
-making modifications to it. For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable. However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-@item
-You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-@item
-You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Program or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-@item
-Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-@item
-If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all. For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-@item
-If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded. In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-@item
-The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time. Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Program
-specifies a version number of this License which applies to it and ``any
-later version'', you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation. If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-@item
-If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission. For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this. Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-@center @b{NO WARRANTY}
-
-@item
-BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM ``AS IS'' WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-@item
-IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.

-@unnumberedsec How to Apply These Terms to Your New Programs
-
- If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
- To do so, attach the following notices to the program. It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the ``copyright'' line and a pointer to where the full notice is found.
-
-@smallexample
-@var{one line to give the program's name and an idea of what it does.}
-Copyright (C) 19@var{yy} @var{name of author}
-
-This program is free software; you can redistribute it and/or
-modify it under the terms of the GNU General Public License
-as published by the Free Software Foundation; either version 2
-of the License, or (at your option) any later version.
-
-This program is distributed in the hope that it will be useful,
-but WITHOUT ANY WARRANTY; without even the implied warranty of
-MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
-GNU General Public License for more details.
-
-You should have received a copy of the GNU General Public License along
-with this program; if not, write to the Free Software Foundation, Inc.,
-59 Temple Place, Suite 330, Boston, MA 02111-1307, USA.
-@end smallexample
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-@smallexample
-Gnomovision version 69, Copyright (C) 19@var{yy} @var{name of author}
-Gnomovision comes with ABSOLUTELY NO WARRANTY; for details
-type `show w'. This is free software, and you are welcome
-to redistribute it under certain conditions; type `show c'
-for details.
-@end smallexample
-
-The hypothetical commands @samp{show w} and @samp{show c} should show
-the appropriate parts of the General Public License. Of course, the
-commands you use may be called something other than @samp{show w} and
-@samp{show c}; they could even be mouse-clicks or menu items---whatever
-suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a ``copyright disclaimer'' for the program, if
-necessary. Here is a sample; alter the names:
-
-@smallexample
-@group
-Yoyodyne, Inc., hereby disclaims all copyright
-interest in the program `Gnomovision'
-(which makes passes at compilers) written
-by James Hacker.
+This exception does not invalidate any other reasons why a work based on this
+file might be covered by the GNU General Public License.
-@var{signature of Ty Coon}, 1 April 1989
-Ty Coon, President of Vice
-@end group
-@end smallexample
-This General Public License does not permit incorporating your program into
-proprietary programs. If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library. If this is what you want to do, use the GNU Library General
-Public License instead of this License.

+usage="Usage: $prog [OPTION]... PACKAGE MANUAL-TITLE
+
+Generate output in various formats from PACKAGE.texinfo (or .texi or
+.txi) source. See the GNU Maintainers document for a more extensive
+discussion:
+ http://www.gnu.org/prep/maintain_toc.html
+
+Options:
+ -s SRCFILE read Texinfo from SRCFILE, instead of PACKAGE.{texinfo|texi|txi}
+ -o OUTDIR write files into OUTDIR, instead of manual/.
+ --email ADR use ADR as contact in generated web pages.
+ --docbook convert to DocBook too (xml, txt, html, pdf and ps).
+ --html ARG pass indicated ARG to makeinfo or texi2html for HTML targets.
+ --info ARG pass indicated ARG to makeinfo for Info, instead of --no-split.
+ --texi2html use texi2html to generate HTML targets.
+ --help display this help and exit successfully.
+ --version display version information and exit successfully.
+
+Simple example: $prog --email bug-gnu-emacs@gnu.org emacs \"GNU Emacs Manual\"
+
+Typical sequence:
+ cd PACKAGESOURCE/doc
+ wget \"$scripturl\"
+ wget \"$templateurl\"
+ $prog --email BUGLIST MANUAL \"GNU MANUAL - One-line description\"
+
+Output will be in a new subdirectory \"manual\" (by default;
+use -o OUTDIR to override). Move all the new files into your web CVS
+tree, as explained in the Web Pages node of maintain.texi.
+
+Please do use the --email ADDRESS option to specify your bug-reporting
+address in the generated HTML pages.
+
+MANUAL-TITLE is included as part of the HTML <title> of the overall
+manual/index.html file. It should include the name of the package being
+documented. manual/index.html is created by substitution from the file
+$GENDOCS_TEMPLATE_DIR/gendocs_template. (Feel free to modify the
+generic template for your own purposes.)
+
+If you have several manuals, you'll need to run this script several
+times with different MANUAL values, specifying a different output
+directory with -o each time. Then write (by hand) an overall index.html
+with links to them all.
+
+If a manual's Texinfo sources are spread across several directories,
+first copy or symlink all Texinfo sources into a single directory.
+(Part of the script's work is to make a tar.gz of the sources.)
+
+As implied above, by default monolithic Info files are generated.
+If you want split Info, or other Info options, use --info to override.
+
+You can set the environment variables MAKEINFO, TEXI2DVI, TEXI2HTML, and
+DVIPS to control the programs that get executed, and
+GENDOCS_TEMPLATE_DIR to control where the gendocs_template file is
+looked for. With --docbook, the environment variables DOCBOOK2HTML,
+DOCBOOK2PDF, DOCBOOK2PS, and DOCBOOK2TXT are also respected.
+
+By default, makeinfo and texi2dvi are run in the default (English)
+locale, since that's the language of most Texinfo manuals. If you
+happen to have a non-English manual and non-English web site, see the
+SETLANG setting in the source.
+
+Email bug reports or enhancement requests to bug-texinfo@gnu.org.

+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.

+
+@heading Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software---to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+@heading TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+@enumerate 0
+@item
+This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The ``Program'', below,
+refers to any such program or work, and a ``work based on the Program''
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term ``modification''.) Each licensee is addressed as ``you''.
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+@item
+You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+@item
+You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+@enumerate a
+@item
+You must cause the modified files to carry prominent notices
+stating that you changed the files and the date of any change.
+
+@item
+You must cause any work that you distribute or publish, that in
+whole or in part contains or is derived from the Program or any
+part thereof, to be licensed as a whole at no charge to all third
+parties under the terms of this License.
+
+@item
+If the modified program normally reads commands interactively
+when run, you must cause it, when started running for such
+interactive use in the most ordinary way, to print or display an
+announcement including an appropriate copyright notice and a
+notice that there is no warranty (or else, saying that you provide
+a warranty) and that users may redistribute the program under
+these conditions, and telling the user how to view a copy of this
+License. (Exception: if the Program itself is interactive but
+does not normally print such an announcement, your work based on
+the Program is not required to print an announcement.)
+@end enumerate
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+@item
+You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+@enumerate a
+@item
+Accompany it with the complete corresponding machine-readable
+source code, which must be distributed under the terms of Sections
+1 and 2 above on a medium customarily used for software interchange; or,
+
+@item
+Accompany it with a written offer, valid for at least three
+years, to give any third party, for a charge no more than your
+cost of physically performing source distribution, a complete
+machine-readable copy of the corresponding source code, to be
+distributed under the terms of Sections 1 and 2 above on a medium
+customarily used for software interchange; or,
+
+@item
+Accompany it with the information you received as to the offer
+to distribute corresponding source code. (This alternative is
+allowed only for noncommercial distribution and only if you
+received the program in object code or executable form with such
+an offer, in accord with Subsection b above.)
+@end enumerate
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+@item
+You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+@item
+You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+@item
+Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+@item
+If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+@item
+If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+@item
+The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and ``any
+later version'', you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+@item
+If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.

+@heading Appendix: How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the ``copyright'' line and a pointer to where the full notice is found.
+
+@smallexample
+@var{one line to give the program's name and a brief idea of what it does.}
+Copyright (C) @var{yyyy} @var{name of author}
+
+This program is free software; you can redistribute it and/or modify
+it under the terms of the GNU General Public License as published by
+the Free Software Foundation; either version 2 of the License, or
+(at your option) any later version.
+
+This program is distributed in the hope that it will be useful,
+but WITHOUT ANY WARRANTY; without even the implied warranty of
+MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+GNU General Public License for more details.
+
+You should have received a copy of the GNU General Public License
+along with this program; if not, write to the Free Software
+Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA.
+@end smallexample
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+@smallexample
+Gnomovision version 69, Copyright (C) @var{year} @var{name of author}
+Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+This is free software, and you are welcome to redistribute it
+under certain conditions; type `show c' for details.
+@end smallexample
+
+The hypothetical commands @samp{show w} and @samp{show c} should show
+the appropriate parts of the General Public License. Of course, the
+commands you use may be called something other than @samp{show w} and
+@samp{show c}; they could even be mouse-clicks or menu items---whatever
+suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a ``copyright disclaimer'' for the program, if
+necessary. Here is a sample; alter the names:
+
+@example
+Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+`Gnomovision' (which makes passes at compilers) written by James Hacker.

+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

-1 Introduction
-**************
-
-This tutorial is for developers who want to learn how they can add HTTP
-serving capabilities to their applications with the _GNU libmicrohttpd_
-library, abbreviated _MHD_. The reader will learn how to implement
-basic HTTP functions from simple executable sample programs that
-implement various features.
-
- The text is supposed to be a supplement to the API reference manual
-of _GNU libmicrohttpd_ and for that reason does not explain many of the
-parameters. Therefore, the reader should always consult the manual to
-find the exact meaning of the functions used in the tutorial.
-Furthermore, the reader is encouraged to study the relevant _RFCs_,
-which document the HTTP standard.
-
- _GNU libmicrohttpd_ is assumed to be already installed. This
-tutorial is written for version 0.9.23. At the time being, this
-tutorial has only been tested on _GNU/Linux_ machines even though
-efforts were made not to rely on anything that would prevent the
-samples from being built on similar systems.
-
-1.1 History
-===========
-
-This tutorial was originally written by Sebastian Gerhardt for MHD
-0.4.0. It was slighly polished and updated to MHD 0.9.0 by Christian
-Grothoff.
-
-
-File: libmicrohttpd-tutorial.info, Node: Hello browser example, Next: Exploring requests, Prev: Introduction, Up: Top
-
-2 Hello browser example
-***********************
-
-The most basic task for a HTTP server is to deliver a static text
-message to any client connecting to it. Given that this is also easy
-to implement, it is an excellent problem to start with.
-
- For now, the particular URI the client asks for shall have no effect
-on the message that will be returned. In addition, the server shall end
-the connection after the message has been sent so that the client will
-know there is nothing more to expect.
-
- The C program `hellobrowser.c', which is to be found in the examples
-section, does just that. If you are very eager, you can compile and
-start it right away but it is advisable to type the lines in by
-yourself as they will be discussed and explained in detail.
-
- After the necessary includes and the definition of the port which
-our server should listen on
-#include <sys/types.h>
-#include <sys/select.h>
-#include <sys/socket.h>
-#include <microhttpd.h>
-
-#define PORT 8888
-
-the desired behaviour of our server when HTTP request arrive has to be
-implemented. We already have agreed that it should not care about the
-particular details of the request, such as who is requesting what. The
-server will respond merely with the same small HTML page to every
-request.
-
- The function we are going to write now will be called by _GNU
-libmicrohttpd_ every time an appropriate request comes in. While the
-name of this callback function is arbitrary, its parameter list has to
-follow a certain layout. So please, ignore the lot of parameters for
-now, they will be explained at the point they are needed. We have to
-use only one of them, `struct MHD_Connection *connection', for the
-minimalistic functionality we want to archive at the moment.
-
- This parameter is set by the _libmicrohttpd_ daemon and holds the
-necessary information to relate the call with a certain connection.
-Keep in mind that a server might have to satisfy hundreds of concurrent
-connections and we have to make sure that the correct data is sent to
-the destined client. Therefore, this variable is a means to refer to a
-particular connection if we ask the daemon to sent the reply.
-
- Talking about the reply, it is defined as a string right after the
-function header
-int answer_to_connection (void *cls, struct MHD_Connection *connection,
- const char *url,
- const char *method, const char *version,
- const char *upload_data,
- size_t *upload_data_size, void **con_cls)
-{
- const char *page = "<html><body>Hello, browser!</body></html>";
-
-HTTP is a rather strict protocol and the client would certainly
-consider it "inappropriate" if we just sent the answer string "as is".
-Instead, it has to be wrapped with additional information stored in
-so-called headers and footers. Most of the work in this area is done
-by the library for us--we just have to ask. Our reply string packed in
-the necessary layers will be called a "response". To obtain such a
-response we hand our data (the reply-string) and its size over to the
-`MHD_create_response_from_buffer' function. The last two parameters
-basically tell _MHD_ that we do not want it to dispose the message data
-for us when it has been sent and there also needs no internal copy to
-be done because the _constant_ string won't change anyway.
-
- struct MHD_Response *response;
- int ret;
-
- response = MHD_create_response_from_buffer (strlen (page),
- (void*) page, MHD_RESPMEM_PERSISTENT);
-
-Now that the the response has been laced up, it is ready for delivery
-and can be queued for sending. This is done by passing it to another
-_GNU libmicrohttpd_ function. As all our work was done in the scope of
-one function, the recipient is without doubt the one associated with the
-local variable `connection' and consequently this variable is given to
-the queue function. Every HTTP response is accompanied by a status
-code, here "OK", so that the client knows this response is the intended
-result of his request and not due to some error or malfunction.
-
- Finally, the packet is destroyed and the return value from the queue
-returned, already being set at this point to either MHD_YES or MHD_NO
-in case of success or failure.
-
- ret = MHD_queue_response (connection, MHD_HTTP_OK, response);
- MHD_destroy_response (response);
-
- return ret;
-}
-
-With the primary task of our server implemented, we can start the
-actual server daemon which will listen on `PORT' for connections. This
-is done in the main function.
-int main ()
-{
- struct MHD_Daemon *daemon;
-
- daemon = MHD_start_daemon (MHD_USE_SELECT_INTERNALLY, PORT, NULL, NULL,
- &answer_to_connection, NULL, MHD_OPTION_END);
- if (NULL == daemon) return 1;
-
-The first parameter is one of three possible modes of operation. Here
-we want the daemon to run in a separate thread and to manage all
-incoming connections in the same thread. This means that while
-producing the response for one connection, the other connections will
-be put on hold. In this example, where the reply is already known and
-therefore the request is served quickly, this poses no problem.
-
- We will allow all clients to connect regardless of their name or
-location, therefore we do not check them on connection and set the
-forth and fifth parameter to NULL.
-
- Parameter six is the address of the function we want to be called
-whenever a new connection has been established. Our
-`answer_to_connection' knows best what the client wants and needs no
-additional information (which could be passed via the next parameter)
-so the next parameter is NULL. Likewise, we do not need to pass extra
-options to the daemon so we just write the MHD_OPTION_END as the last
-parameter.
-
- As the server daemon runs in the background in its own thread, the
-execution flow in our main function will contine right after the call.
-Because of this, we must delay the execution flow in the main thread or
-else the program will terminate prematurely. We let it pause in a
-processing-time friendly manner by waiting for the enter key to be
-pressed. In the end, we stop the daemon so it can do its cleanup tasks.
- getchar ();
-
- MHD_stop_daemon (daemon);
- return 0;
-}
-
-The first example is now complete.
-
- Compile it with
-cc hellobrowser.c -o hellobrowser -I$PATH_TO_LIBMHD_INCLUDES
- -L$PATH_TO_LIBMHD_LIBS -lmicrohttpd
- with the two paths set accordingly and run it.
-
- Now open your favorite Internet browser and go to the address
-`http://localhost:8888/', provided that 8888 is the port you chose. If
-everything works as expected, the browser will present the message of
-the static HTML page it got from our minimal server.
-
-Remarks
-=======
-
-To keep this first example as small as possible, some drastic shortcuts
-were taken and are to be discussed now.
-
- Firstly, there is no distinction made between the kinds of requests
-a client could send. We implied that the client sends a GET request,
-that means, that he actually asked for some data. Even when it is not
-intended to accept POST requests, a good server should at least
-recognize that this request does not constitute a legal request and
-answer with an error code. This can be easily implemented by checking
-if the parameter `method' equals the string "GET" and returning a
-`MHD_NO' if not so.
-
- Secondly, the above practice of queuing a response upon the first
-call of the callback function brings with it some limitations. This is
-because the content of the message body will not be received if a
-response is queued in the first iteration. Furthermore, the connection
-will be closed right after the response has been transferred then.
-This is typically not what you want as it disables HTTP pipelining.
-The correct approach is to simply not queue a message on the first
-callback unless there is an error. The `void**' argument to the
-callback provides a location for storing information about the history
-of the connection; for the first call, the pointer will point to NULL.
-A simplistic way to differenciate the first call from others is to check
-if the pointer is NULL and set it to a non-NULL value during the first
-call.
-
- Both of these issues you will find addressed in the official
-`minimal_example.c' residing in the `src/examples' directory of the
-_MHD_ package. The source code of this program should look very
-familiar to you by now and easy to understand.
-
- For our example, the `must_copy' and `must_free' parameter at the
-response construction function could be set to `MHD_NO'. In the usual
-case, responses cannot be sent immediately after being queued. For
-example, there might be other data on the system that needs to be sent
-with a higher priority. Nevertheless, the queue function will return
-successfully--raising the problem that the data we have pointed to may
-be invalid by the time it is about being sent. This is not an issue
-here because we can expect the `page' string, which is a constant
-_string literal_ here, to be static. That means it will be present and
-unchanged for as long as the program runs. For dynamic data, one could
-choose to either have _MHD_ free the memory `page' points to itself
-when it is not longer needed or, alternatively, have the library to
-make and manage its own copy of it.
-
-Exercises
-=========
-
- * While the server is running, use a program like `telnet' or
- `netcat' to connect to it. Try to form a valid HTTP 1.1 request
- yourself like GET /dontcare HTTP/1.1
- Host: itsme
- <enter>
- and see what the server returns to you.
-
- * Also, try other requests, like POST, and see how our server does
- not mind and why. How far in malforming a request can you go
- before the builtin functionality of _MHD_ intervenes and an
- altered response is sent? Make sure you read about the status
- codes in the _RFC_.
-
- * Add the option `MHD_USE_PEDANTIC_CHECKS' to the start function of
- the daemon in `main'. Mind the special format of the parameter
- list here which is described in the manual. How indulgent is the
- server now to your input?
-
- * Let the main function take a string as the first command line
- argument and pass `argv[1]' to the `MHD_start_daemon' function as
- the sixth parameter. The address of this string will be passed to
- the callback function via the `cls' variable. Decorate the text
- given at the command line when the server is started with proper
- HTML tags and send it as the response instead of the former static
- string.
-
- * _Demanding:_ Write a separate function returning a string
- containing some useful information, for example, the time. Pass
- the function's address as the sixth parameter and evaluate this
- function on every request anew in `answer_to_connection'. Remember
- to free the memory of the string every time after satisfying the
- request.

-3 Exploring requests
-********************
-
-This chapter will deal with the information which the client sends to
-the server at every request. We are going to examine the most useful
-fields of such an request and print them out in a readable manner. This
-could be useful for logging facilities.
-
- The starting point is the _hellobrowser_ program with the former
-response removed.
-
- This time, we just want to collect information in the callback
-function, thus we will just return MHD_NO after we have probed the
-request. This way, the connection is closed without much ado by the
-server.
-
-static int
-answer_to_connection (void *cls, struct MHD_Connection *connection,
- const char *url,
- const char *method, const char *version,
- const char *upload_data,
- size_t *upload_data_size, void **con_cls)
-{
- ...
- return MHD_NO;
-}
- The ellipsis marks the position where the following instructions shall
-be inserted.
-
- We begin with the most obvious information available to the server,
-the request line. You should already have noted that a request consists
-of a command (or "HTTP method") and a URI (e.g. a filename). It also
-contains a string for the version of the protocol which can be found in
-`version'. To call it a "new request" is justified because we return
-only `MHD_NO', thus ensuring the function will not be called again for
-this connection.
-printf ("New %s request for %s using version %s\n", method, url, version);
- The rest of the information is a bit more hidden. Nevertheless, there
-is lot of it sent from common Internet browsers. It is stored in
-"key-value" pairs and we want to list what we find in the header. As
-there is no mandatory set of keys a client has to send, each key-value
-pair is printed out one by one until there are no more left. We do this
-by writing a separate function which will be called for each pair just
-like the above function is called for each HTTP request. It can then
-print out the content of this pair.
-int print_out_key (void *cls, enum MHD_ValueKind kind,
- const char *key, const char *value)
-{
- printf ("%s: %s\n", key, value);
- return MHD_YES;
-}
- To start the iteration process that calls our new function for every
-key, the line
-MHD_get_connection_values (connection, MHD_HEADER_KIND, &print_out_key, NULL);
- needs to be inserted in the connection callback function too. The
-second parameter tells the function that we are only interested in keys
-from the general HTTP header of the request. Our iterating function
-`print_out_key' does not rely on any additional information to fulfill
-its duties so the last parameter can be NULL.
-
- All in all, this constitutes the complete `logging.c' program for
-this chapter which can be found in the `examples' section.
-
- Connecting with any modern Internet browser should yield a handful
-of keys. You should try to interpret them with the aid of _RFC 2616_.
-Especially worth mentioning is the "Host" key which is often used to
-serve several different websites hosted under one single IP address but
-reachable by different domain names (this is called virtual hosting).
-
-Conclusion
-==========
-
-The introduced capabilities to itemize the content of a simple GET
-request--especially the URI--should already allow the server to satisfy
-clients' requests for small specific resources (e.g. files) or even
-induce alteration of server state. However, the latter is not
-recommended as the GET method (including its header data) is by
-convention considered a "safe" operation, which should not change the
-server's state in a significant way. By convention, GET operations can
-thus be performed by crawlers and other automatic software. Naturally
-actions like searching for a passed string are fine.
-
- Of course, no transmission can occur while the return value is still
-set to `MHD_NO' in the callback function.
-
-Exercises
-=========
-
- * By parsing the `url' string and delivering responses accordingly,
- implement a small server for "virtual" files. When asked for
- `/index.htm{l}', let the response consist of a HTML page
- containing a link to `/another.html' page which is also to be
- created "on the fly" in case of being requested. If neither of
- these two pages are requested, `MHD_HTTP_NOT_FOUND' shall be
- returned accompanied by an informative message.
-
- * A very interesting information has still been ignored by our
- logger--the client's IP address. Implement a callback function static int on_client_connect (void *cls,
- const struct sockaddr *addr,
- socklen_t addrlen)
- that prints out the IP address in an appropriate format. You
- might want to use the POSIX function `inet_ntoa' but bear in mind
- that `addr' is actually just a structure containing other
- substructures and is _not_ the variable this function expects.
- Make sure to return `MHD_YES' so that the library knows the client
- is allowed to connect (and to then process the request). If one
- wanted to limit access basing on IP addresses, this would be the
- place to do it. The address of your `on_client_connect' function
- must be passed as the third parameter to the `MHD_start_daemon'
- call.

-4 Response headers
-******************
-
-Now that we are able to inspect the incoming request in great detail,
-this chapter discusses the means to enrich the outgoing responses
-likewise.
-
- As you have learned in the _Hello, Browser_ chapter, some obligatory
-header fields are added and set automatically for simple responses by
-the library itself but if more advanced features are desired,
-additional fields have to be created. One of the possible fields is
-the content type field and an example will be developed around it.
-This will lead to an application capable of correctly serving different
-types of files.
-
- When we responded with HTML page packed in the static string
-previously, the client had no choice but guessing about how to handle
-the response, because the server had not told him. What if we had sent
-a picture or a sound file? Would the message have been understood or
-merely been displayed as an endless stream of random characters in the
-browser? This is what the mime content types are for. The header of
-the response is extended by certain information about how the data is
-to be interpreted.
-
- To introduce the concept, a picture of the format _PNG_ will be sent
-to the client and labeled accordingly with `image/png'. Once again, we
-can base the new example on the `hellobrowser' program.
-
-#define FILENAME "picture.png"
-#define MIMETYPE "image/png"
-
-static int
-answer_to_connection (void *cls, struct MHD_Connection *connection,
- const char *url,
- const char *method, const char *version,
- const char *upload_data,
- size_t *upload_data_size, void **con_cls)
-{
- unsigned char *buffer = NULL;
- struct MHD_Response *response;
- We want the program to open the file for reading and determine its
-size:
- int fd;
- int ret;
- struct stat sbuf;
-
- if (0 != strcmp (method, "GET"))
- return MHD_NO;
- if ( (-1 == (fd = open (FILENAME, O_RDONLY))) ||
- (0 != fstat (fd, &sbuf)) )
- {
- /* error accessing file */
- /* ... (see below) */
- }
- /* ... (see below) */
- When dealing with files, there is a lot that could go wrong on the
-server side and if so, the client should be informed with
-`MHD_HTTP_INTERNAL_SERVER_ERROR'.
-
- /* error accessing file */
- if (fd != -1) close (fd);
- const char *errorstr =
- "<html><body>An internal server error has occured!\
- </body></html>";
- response =
- MHD_create_response_from_buffer (strlen (errorstr),
- (void *) errorstr,
- MHD_RESPMEM_PERSISTENT);
- if (response)
- {
- ret =
- MHD_queue_response (connection, MHD_HTTP_INTERNAL_SERVER_ERROR,
- response);
- MHD_destroy_response (response);
-
- return MHD_YES;
- }
- else
- return MHD_NO;
- if (!ret)
- {
- const char *errorstr = "<html><body>An internal server error has occured!\
- </body></html>";
-
- if (buffer) free(buffer);
-
- response = MHD_create_response_from_buffer (strlen(errorstr), (void*) errorstr,
- MHD_RESPMEM_PERSISTENT);
-
- if (response)
- {
- ret = MHD_queue_response (connection,
- MHD_HTTP_INTERNAL_SERVER_ERROR,
- response);
- MHD_destroy_response (response);
-
- return MHD_YES;
- }
- else return MHD_NO;
- }
- Note that we nevertheless have to create a response object even for
-sending a simple error code. Otherwise, the connection would just be
-closed without comment, leaving the client curious about what has
-happened.
-
- But in the case of success a response will be constructed directly
-from the file descriptor:
-
- /* error accessing file */
- /* ... (see above) */
- }
-
- response =
- MHD_create_response_from_fd_at_offset (sbuf.st_size, fd, 0);
- MHD_add_response_header (response, "Content-Type", MIMETYPE);
- ret = MHD_queue_response (connection, MHD_HTTP_OK, response);
- MHD_destroy_response (response);
- Note that the response object will take care of closing the file
-desciptor for us.
-
- Up to this point, there was little new. The actual novelty is that
-we enhance the header with the meta data about the content. Aware of
-the field's name we want to add, it is as easy as that:
-MHD_add_response_header(response, "Content-Type", MIMETYPE);
- We do not have to append a colon expected by the protocol behind the
-first field--_GNU libhttpdmicro_ will take care of this.
-
- The function finishes with the well-known lines
- ret = MHD_queue_response (connection, MHD_HTTP_OK, response);
- MHD_destroy_response (response);
- return ret;
-}
- The complete program `responseheaders.c' is in the `examples' section
-as usual. Find a _PNG_ file you like and save it to the directory the
-example is run from under the name `picture.png'. You should find the
-image displayed on your browser if everything worked well.
-
-Remarks
-=======
-
-The include file of the _MHD_ library comes with the header types
-mentioned in _RFC 2616_ already defined as macros. Thus, we could have
-written `MHD_HTTP_HEADER_CONTENT_TYPE' instead of `"Content-Type"' as
-well. However, one is not limited to these standard headers and could
-add custom response headers without violating the protocol. Whether,
-and how, the client would react to these custom header is up to the
-receiver. Likewise, the client is allowed to send custom request
-headers to the server as well, opening up yet more possibilities how
-client and server could communicate with each other.
-
- The method of creating the response from a file on disk only works
-for static content. Serving dynamically created responses will be a
-topic of a future chapter.
-
-Exercises
-=========
-
- * Remember that the original program was written under a few
- assumptions--a static response using a local file being one of
- them. In order to simulate a very large or hard to reach file that
- cannot be provided instantly, postpone the queuing in the callback
- with the `sleep' function for 30 seconds _if_ the file `/big.png'
- is requested (but deliver the same as above). A request for
- `/picture.png' should provide just the same but without any
- artificial delays.
-
- Now start two instances of your browser (or even use two machines)
- and see how the second client is put on hold while the first waits
- for his request on the slow file to be fulfilled.
-
- Finally, change the sourcecode to use
- `MHD_USE_THREAD_PER_CONNECTION' when the daemon is started and try
- again.
-
- * Did you succeed in implementing the clock exercise yet? This time,
- let the server save the program's start time `t' and implement a
- response simulating a countdown that reaches 0 at `t+60'.
- Returning a message saying on which point the countdown is, the
- response should ultimately be to reply "Done" if the program has
- been running long enough,
-
- An unofficial, but widely understood, response header line is
- `Refresh: DELAY; url=URL' with the uppercase words substituted to
- tell the client it should request the given resource after the
- given delay again. Improve your program in that the browser (any
- modern browser should work) automatically reconnects and asks for
- the status again every 5 seconds or so. The URL would have to be
- composed so that it begins with "http://", followed by the _URI_
- the server is reachable from the client's point of view.
-
- Maybe you want also to visualize the countdown as a status bar by
- creating a `<table>' consisting of one row and `n' columns whose
- fields contain small images of either a red or a green light.

-5 Supporting basic authentication
-*********************************
-
-With the small exception of IP address based access control, requests
-from all connecting clients where served equally until now. This
-chapter discusses a first method of client's authentication and its
-limits.
-
- A very simple approach feasible with the means already discussed
-would be to expect the password in the _URI_ string before granting
-access to the secured areas. The password could be separated from the
-actual resource identifier by a certain character, thus the request
-line might look like
-GET /picture.png?mypassword
- In the rare situation where the client is customized enough and the
-connection occurs through secured lines (e.g., a embedded device
-directly attached to another via wire) and where the ability to embedd
-a password in the URI or to pass on a URI with a password are desired,
-this can be a reasonable choice.
-
- But when it is assumed that the user connecting does so with an
-ordinary Internet browser, this implementation brings some problems
-about. For example, the URI including the password stays in the address
-field or at least in the history of the browser for anybody near enough
-to see. It will also be inconvenient to add the password manually to
-any new URI when the browser does not know how to compose this
-automatically.
-
- At least the convenience issue can be addressed by employing the
-simplest built-in password facilities of HTTP compliant browsers, hence
-we want to start there. It will however turn out to have still severe
-weaknesses in terms of security which need consideration.
-
- Before we will start implementing _Basic Authentication_ as
-described in _RFC 2617_, we should finally abandon the bad practice of
-responding every request the first time our callback is called for a
-given connection. This is becoming more important now because the
-client and the server will have to talk in a more bi-directional way
-than before to
-
- But how can we tell whether the callback has been called before for
-the particular connection? Initially, the pointer this parameter
-references is set by _MHD_ in the callback. But it will also be
-"remembered" on the next call (for the same connection). Thus, we will
-generate no response until the parameter is non-null--implying the
-callback was called before at least once. We do not need to share
-information between different calls of the callback, so we can set the
-parameter to any adress that is assured to be not null. The pointer to
-the `connection' structure will be pointing to a legal address, so we
-take this.
-
- The first time `answer_to_connection' is called, we will not even
-look at the headers.
-
-static int
-answer_to_connection (void *cls, struct MHD_Connection *connection,
- const char *url, const char *method, const char *version,
- const char *upload_data, size_t *upload_data_size,
- void **con_cls)
-{
- if (0 != strcmp(method, "GET")) return MHD_NO;
- if (NULL == *con_cls) {*con_cls = connection; return MHD_YES;}
-
- ...
- /* else respond accordingly */
- ...
-}
- Note how we lop off the connection on the first condition (no "GET"
-request), but return asking for more on the other one with `MHD_YES'.
-With this minor change, we can proceed to implement the actual
-authentication process.
-
-Request for authentication
-==========================
-
-Let us assume we had only files not intended to be handed out without
-the correct username/password, so every "GET" request will be
-challenged. _RFC 2617_ describes how the server shall ask for
-authentication by adding a _WWW-Authenticate_ response header with the
-name of the _realm_ protected. MHD can generate and queue such a
-failure response for you using the `MHD_queue_basic_auth_fail_response'
-API. The only thing you need to do is construct a response with the
-error page to be shown to the user if he aborts basic authentication.
-But first, you should check if the proper credentials were already
-supplied using the `MHD_basic_auth_get_username_password' call.
-
- Your code would then look like this:
-static int
-answer_to_connection (void *cls, struct MHD_Connection *connection,
- const char *url, const char *method,
- const char *version, const char *upload_data,
- size_t *upload_data_size, void **con_cls)
-{
- char *user;
- char *pass;
- int fail;
- struct MHD_Response *response;
-
- if (0 != strcmp (method, MHD_HTTP_METHOD_GET))
- return MHD_NO;
- if (NULL == *con_cls)
- {
- *con_cls = connection;
- return MHD_YES;
- }
- pass = NULL;
- user = MHD_basic_auth_get_username_password (connection, &pass);
- fail = ( (user == NULL) ||
- (0 != strcmp (user, "root")) ||
- (0 != strcmp (pass, "pa$$w0rd") ) );
- if (user != NULL) free (user);
- if (pass != NULL) free (pass);
- if (fail)
- {
- const char *page = "<html><body>Go away.</body></html>";
- response =
- MHD_create_response_from_buffer (strlen (page), (void *) page,
- MHD_RESPMEM_PERSISTENT);
- ret = MHD_queue_basic_auth_fail_response (connection,
- "my realm",
- response);
- }
- else
- {
- const char *page = "<html><body>A secret.</body></html>";
- response =
- MHD_create_response_from_buffer (strlen (page), (void *) page,
- MHD_RESPMEM_PERSISTENT);
- ret = MHD_queue_response (connection, MHD_HTTP_OK, response);
- }
- MHD_destroy_response (response);
- return ret;
-}
-
- See the `examples' directory for the complete example file.
-
-Remarks
-=======
-
-For a proper server, the conditional statements leading to a return of
-`MHD_NO' should yield a response with a more precise status code
-instead of silently closing the connection. For example, failures of
-memory allocation are best reported as _internal server error_ and
-unexpected authentication methods as _400 bad request_.
-
-Exercises
-=========
-
- * Make the server respond to wrong credentials (but otherwise
- well-formed requests) with the recommended _401 unauthorized_
- status code. If the client still does not authenticate correctly
- within the same connection, close it and store the client's IP
- address for a certain time. (It is OK to check for expiration not
- until the main thread wakes up again on the next connection.) If
- the client fails authenticating three times during this period,
- add it to another list for which the `AcceptPolicyCallback'
- function denies connection (temporally).
-
- * With the network utility `netcat' connect and log the response of
- a "GET" request as you did in the exercise of the first example,
- this time to a file. Now stop the server and let _netcat_ listen
- on the same port the server used to listen on and have it fake
- being the proper server by giving the file's content as the
- response (e.g. `cat log | nc -l -p 8888'). Pretending to think
- your were connecting to the actual server, browse to the
- eavesdropper and give the correct credentials.
-
- Copy and paste the encoded string you see in `netcat''s output to
- some of the Base64 decode tools available online and see how both
- the user's name and password could be completely restored.

-6 Processing POST data
-**********************
-
-The previous chapters already have demonstrated a variety of
-possibilities to send information to the HTTP server, but it is not
-recommended that the _GET_ method is used to alter the way the server
-operates. To induce changes on the server, the _POST_ method is
-preferred over and is much more powerful than _GET_ and will be
-introduced in this chapter.
-
- We are going to write an application that asks for the visitor's
-name and, after the user has posted it, composes an individual response
-text. Even though it was not mandatory to use the _POST_ method here,
-as there is no permanent change caused by the POST, it is an
-illustrative example on how to share data between different functions
-for the same connection. Furthermore, the reader should be able to
-extend it easily.
-
-GET request
-===========
-
-When the first _GET_ request arrives, the server shall respond with a
-HTML page containing an edit field for the name.
-
-const char* askpage = "<html><body>\
- What's your name, Sir?<br>\
- <form action=\"/namepost\" method=\"post\">\
- <input name=\"name\" type=\"text\"\
- <input type=\"submit\" value=\" Send \"></form>\
- </body></html>";
- The `action' entry is the _URI_ to be called by the browser when
-posting, and the `name' will be used later to be sure it is the
-editbox's content that has been posted.
-
- We also prepare the answer page, where the name is to be filled in
-later, and an error page as the response for anything but proper _GET_
-and _POST_ requests:
-
-const char* greatingpage="<html><body><h1>Welcome, %s!</center></h1></body></html>";
-
-const char* errorpage="<html><body>This doesn't seem to be right.</body></html>";
- Whenever we need to send a page, we use an extra function `int
-send_page(struct MHD_Connection *connection, const char* page)' for
-this, which does not contain anything new and whose implementation is
-therefore not discussed further in the tutorial.
-
-POST request
-============
-
-Posted data can be of arbitrary and considerable size; for example, if
-a user uploads a big image to the server. Similar to the case of the
-header fields, there may also be different streams of posted data, such
-as one containing the text of an editbox and another the state of a
-button. Likewise, we will have to register an iterator function that
-is going to be called maybe several times not only if there are
-different POSTs but also if one POST has only been received partly yet
-and needs processing before another chunk can be received.
-
- Such an iterator function is called by a _postprocessor_, which must
-be created upon arriving of the post request. We want the iterator
-function to read the first post data which is tagged `name' and to
-create an individual greeting string based on the template and the name.
-But in order to pass this string to other functions and still be able
-to differentiate different connections, we must first define a
-structure to share the information, holding the most import entries.
-
-struct connection_info_struct
-{
- int connectiontype;
- char *answerstring;
- struct MHD_PostProcessor *postprocessor;
-};
- With these information available to the iterator function, it is able
-to fulfill its task. Once it has composed the greeting string, it
-returns `MHD_NO' to inform the post processor that it does not need to
-be called again. Note that this function does not handle processing of
-data for the same `key'. If we were to expect that the name will be
-posted in several chunks, we had to expand the namestring dynamically
-as additional parts of it with the same `key' came in. But in this
-example, the name is assumed to fit entirely inside one single packet.
-
-static int
-iterate_post (void *coninfo_cls, enum MHD_ValueKind kind, const char *key,
- const char *filename, const char *content_type,
- const char *transfer_encoding, const char *data,
- uint64_t off, size_t size)
-{
- struct connection_info_struct *con_info = coninfo_cls;
-
- if (0 == strcmp (key, "name"))
- {
- if ((size > 0) && (size <= MAXNAMESIZE))
- {
- char *answerstring;
- answerstring = malloc (MAXANSWERSIZE);
- if (!answerstring) return MHD_NO;
-
- snprintf (answerstring, MAXANSWERSIZE, greatingpage, data);
- con_info->answerstring = answerstring;
- }
- else con_info->answerstring = NULL;
-
- return MHD_NO;
- }
-
- return MHD_YES;
-}
- Once a connection has been established, it can be terminated for many
-reasons. As these reasons include unexpected events, we have to
-register another function that cleans up any resources that might have
-been allocated for that connection by us, namely the post processor and
-the greetings string. This cleanup function must take into account that
-it will also be called for finished requests other than _POST_ requests.
-
-void request_completed (void *cls, struct MHD_Connection *connection,
- void **con_cls,
- enum MHD_RequestTerminationCode toe)
-{
- struct connection_info_struct *con_info = *con_cls;
-
- if (NULL == con_info) return;
- if (con_info->connectiontype == POST)
- {
- MHD_destroy_post_processor (con_info->postprocessor);
- if (con_info->answerstring) free (con_info->answerstring);
- }
-
- free (con_info);
- *con_cls = NULL;
-}
- _GNU libmicrohttpd_ is informed that it shall call the above function
-when the daemon is started in the main function.
-
-...

-...
-
-Request handling
-================
-
-With all other functions prepared, we can now discuss the actual
-request handling.
-
- On the first iteration for a new request, we start by allocating a
-new instance of a `struct connection_info_struct' structure, which will
-store all necessary information for later iterations and other
-functions.
-
-static int
-answer_to_connection (void *cls, struct MHD_Connection *connection,
- const char *url,
- const char *method, const char *version,
- const char *upload_data,
- size_t *upload_data_size, void **con_cls)
-{
- if(NULL == *con_cls)
- {
- struct connection_info_struct *con_info;
-
- con_info = malloc (sizeof (struct connection_info_struct));
- if (NULL == con_info) return MHD_NO;
- con_info->answerstring = NULL;
- If the new request is a _POST_, the postprocessor must be created now.
-In addition, the type of the request is stored for convenience.
- if (0 == strcmp (method, "POST"))
- {
- con_info->postprocessor
- = MHD_create_post_processor (connection, POSTBUFFERSIZE,
- iterate_post, (void*) con_info);
-
- if (NULL == con_info->postprocessor)
- {
- free (con_info);
- return MHD_NO;
- }
- con_info->connectiontype = POST;
- }
- else con_info->connectiontype = GET;
- The address of our structure will both serve as the indicator for
-successive iterations and to remember the particular details about the
-connection.
- *con_cls = (void*) con_info;
- return MHD_YES;
- }
- The rest of the function will not be executed on the first iteration.
-A _GET_ request is easily satisfied by sending the question form.
- if (0 == strcmp (method, "GET"))
- {
- return send_page (connection, askpage);
- }
- In case of _POST_, we invoke the post processor for as long as data
-keeps incoming, setting `*upload_data_size' to zero in order to
-indicate that we have processed--or at least have considered--all of it.
- if (0 == strcmp (method, "POST"))
- {
- struct connection_info_struct *con_info = *con_cls;
-
- if (*upload_data_size != 0)
- {
- MHD_post_process (con_info->postprocessor, upload_data,
- *upload_data_size);
- *upload_data_size = 0;
-
- return MHD_YES;
- }
- else if (NULL != con_info->answerstring)
- return send_page (connection, con_info->answerstring);
- }
- Finally, if they are neither _GET_ nor _POST_ requests, the error page
-is returned.
- return send_page(connection, errorpage);
-}
- These were the important parts of the program `simplepost.c'.

-7 Improved processing of POST data
-**********************************
-
-The previous chapter introduced a way to upload data to the server, but
-the developed example program has some shortcomings, such as not being
-able to handle larger chunks of data. In this chapter, we are going to
-discuss a more advanced server program that allows clients to upload a
-file in order to have it stored on the server's filesystem. The server
-shall also watch and limit the number of clients concurrently
-uploading, responding with a proper busy message if necessary.
-
-Prepared answers
-================
-
-We choose to operate the server with the `SELECT_INTERNALLY' method.
-This makes it easier to synchronize the global states at the cost of
-possible delays for other connections if the processing of a request is
-too slow. One of these variables that needs to be shared for all
-connections is the total number of clients that are uploading.
-
-#define MAXCLIENTS 2
-static unsigned int nr_of_uploading_clients = 0;
- If there are too many clients uploading, we want the server to respond
-to all requests with a busy message.
-const char* busypage =
- "<html><body>This server is busy, please try again later.</body></html>";
- Otherwise, the server will send a _form_ that informs the user of the
-current number of uploading clients, and ask her to pick a file on her
-local filesystem which is to be uploaded.
-const char* askpage = "<html><body>\n\
- Upload a file, please!<br>\n\
- There are %u clients uploading at the moment.<br>\n\
- <form action=\"/filepost\" method=\"post\" \
- enctype=\"multipart/form-data\">\n\
- <input name=\"file\" type=\"file\">\n\
- <input type=\"submit\" value=\" Send \"></form>\n\
- </body></html>";
- If the upload has succeeded, the server will respond with a message
-saying so.
-const char* completepage = "<html><body>The upload has been completed.</body></html>";
- We want the server to report internal errors, such as memory shortage
-or file access problems, adequately.
-const char* servererrorpage
- = "<html><body>An internal server error has occured.</body></html>";
-const char* fileexistspage
- = "<html><body>This file already exists.</body></html>";
- It would be tolerable to send all these responses undifferentiated
-with a `200 HTTP_OK' status code but in order to improve the `HTTP'
-conformance of our server a bit, we extend the `send_page' function so
-that it accepts individual status codes.
-
-static int
-send_page (struct MHD_Connection *connection,
- const char* page, int status_code)
-{
- int ret;
- struct MHD_Response *response;
-
- response = MHD_create_response_from_buffer (strlen (page), (void*) page,
- MHD_RESPMEM_MUST_COPY);
- if (!response) return MHD_NO;
-
- ret = MHD_queue_response (connection, status_code, response);
- MHD_destroy_response (response);
-
- return ret;
-}
- Note how we ask _MHD_ to make its own copy of the message data. The
-reason behind this will become clear later.
-
-Connection cycle
-================
-
-The decision whether the server is busy or not is made right at the
-beginning of the connection. To do that at this stage is especially
-important for _POST_ requests because if no response is queued at this
-point, and `MHD_YES' returned, _MHD_ will not sent any queued messages
-until a postprocessor has been created and the post iterator is called
-at least once.
-
-static int
-answer_to_connection (void *cls, struct MHD_Connection *connection,
- const char *url,
- const char *method, const char *version,
- const char *upload_data,
- size_t *upload_data_size, void **con_cls)
-{
- if (NULL == *con_cls)
- {
- struct connection_info_struct *con_info;
-
- if (nr_of_uploading_clients >= MAXCLIENTS)
- return send_page(connection, busypage, MHD_HTTP_SERVICE_UNAVAILABLE);
- If the server is not busy, the `connection_info' structure is
-initialized as usual, with the addition of a filepointer for each
-connection.
-
- con_info = malloc (sizeof (struct connection_info_struct));
- if (NULL == con_info) return MHD_NO;
- con_info->fp = 0;
-
- if (0 == strcmp (method, "POST"))
- {
- ...
- }
- else con_info->connectiontype = GET;
-
- *con_cls = (void*) con_info;
-
- return MHD_YES;
- }
- For _POST_ requests, the postprocessor is created and we register a
-new uploading client. From this point on, there are many possible
-places for errors to occur that make it necessary to interrupt the
-uploading process. We need a means of having the proper response
-message ready at all times. Therefore, the `connection_info' structure
-is extended to hold the most current response message so that whenever
-a response is sent, the client will get the most informative message.
-Here, the structure is initialized to "no error".
- if (0 == strcmp (method, "POST"))
- {
- con_info->postprocessor
- = MHD_create_post_processor (connection, POSTBUFFERSIZE,
- iterate_post, (void*) con_info);
-
- if (NULL == con_info->postprocessor)
- {
- free (con_info);
- return MHD_NO;
- }
-
- nr_of_uploading_clients++;
-
- con_info->connectiontype = POST;
- con_info->answercode = MHD_HTTP_OK;
- con_info->answerstring = completepage;
- }
- else con_info->connectiontype = GET;
- If the connection handler is called for the second time, _GET_
-requests will be answered with the _form_. We can keep the buffer under
-function scope, because we asked _MHD_ to make its own copy of it for
-as long as it is needed.
- if (0 == strcmp (method, "GET"))
- {
- int ret;
- char buffer[1024];
-
- sprintf (buffer, askpage, nr_of_uploading_clients);
- return send_page (connection, buffer, MHD_HTTP_OK);
- }
- The rest of the `answer_to_connection' function is very similar to the
-`simplepost.c' example, except the more flexible content of the
-responses. The _POST_ data is processed until there is none left and
-the execution falls through to return an error page if the connection
-constituted no expected request method.
- if (0 == strcmp (method, "POST"))
- {
- struct connection_info_struct *con_info = *con_cls;
-
- if (0 != *upload_data_size)
- {
- MHD_post_process (con_info->postprocessor,
- upload_data, *upload_data_size);
- *upload_data_size = 0;
-
- return MHD_YES;
- }
- else
- return send_page (connection, con_info->answerstring,
- con_info->answercode);
- }
-
- return send_page(connection, errorpage, MHD_HTTP_BAD_REQUEST);
-}
-
-Storing to data
-===============
-
-Unlike the `simplepost.c' example, here it is to be expected that post
-iterator will be called several times now. This means that for any
-given connection (there might be several concurrent of them) the posted
-data has to be written to the correct file. That is why we store a file
-handle in every `connection_info', so that the it is preserved between
-successive iterations.
-static int
-iterate_post (void *coninfo_cls, enum MHD_ValueKind kind,
- const char *key,
- const char *filename, const char *content_type,
- const char *transfer_encoding, const char *data,
- uint64_t off, size_t size)
-{
- struct connection_info_struct *con_info = coninfo_cls;
- Because the following actions depend heavily on correct file
-processing, which might be error prone, we default to reporting
-internal errors in case anything will go wrong.
-
-con_info->answerstring = servererrorpage;
-con_info->answercode = MHD_HTTP_INTERNAL_SERVER_ERROR;
- In the "askpage" _form_, we told the client to label its post data
-with the "file" key. Anything else would be an error.
-
- if (0 != strcmp (key, "file")) return MHD_NO;
- If the iterator is called for the first time, no file will have been
-opened yet. The `filename' string contains the name of the file
-(without any paths) the user selected on his system. We want to take
-this as the name the file will be stored on the server and make sure no
-file of that name exists (or is being uploaded) before we create one
-(note that the code below technically contains a race between the two
-"fopen" calls, but we will overlook this for portability sake).
- if (!con_info->fp)
- {
- if (NULL != (fp = fopen (filename, "rb")) )
- {
- fclose (fp);
- con_info->answerstring = fileexistspage;
- con_info->answercode = MHD_HTTP_FORBIDDEN;
- return MHD_NO;
- }
-
- con_info->fp = fopen (filename, "ab");
- if (!con_info->fp) return MHD_NO;
- }
- Occasionally, the iterator function will be called even when there are
-0 new bytes to process. The server only needs to write data to the file
-if there is some.
-if (size > 0)
- {
- if (!fwrite (data, size, sizeof(char), con_info->fp))
- return MHD_NO;
- }
- If this point has been reached, everything worked well for this
-iteration and the response can be set to success again. If the upload
-has finished, this iterator function will not be called again.
- con_info->answerstring = completepage;
- con_info->answercode = MHD_HTTP_OK;
-
- return MHD_YES;
-}
- The new client was registered when the postprocessor was created.
-Likewise, we unregister the client on destroying the postprocessor when
-the request is completed.
-void request_completed (void *cls, struct MHD_Connection *connection,
- void **con_cls,
- enum MHD_RequestTerminationCode toe)
-{
- struct connection_info_struct *con_info = *con_cls;
-
- if (NULL == con_info) return;
-
- if (con_info->connectiontype == POST)
- {
- if (NULL != con_info->postprocessor)
- {
- MHD_destroy_post_processor (con_info->postprocessor);
- nr_of_uploading_clients--;
- }
-
- if (con_info->fp) fclose (con_info->fp);
- }
-
- free (con_info);
- *con_cls = NULL;
-}
- This is essentially the whole example `largepost.c'.
-
-Remarks
-=======
-
-Now that the clients are able to create files on the server, security
-aspects are becoming even more important than before. Aside from proper
-client authentication, the server should always make sure explicitly
-that no files will be created outside of a dedicated upload directory.
-In particular, filenames must be checked to not contain strings like
-"../".

-8 Session management
-********************
-
-This chapter discusses how one should manage sessions, that is, share
-state between multiple HTTP requests from the same user. We use a
-simple example where the user submits multiple forms and the server is
-supposed to accumulate state from all of these forms. Naturally, as
-this is a network protocol, our session mechanism must support having
-many users with many concurrent sessions at the same time.
-
- In order to track users, we use a simple session cookie. A session
-cookie expires when the user closes the browser. Changing from session
-cookies to persistent cookies only requires adding an expiration time
-to the cookie. The server creates a fresh session cookie whenever a
-request without a cookie is received, or if the supplied session cookie
-is not known to the server.
-
-Looking up the cookie
-=====================
-
-Since MHD parses the HTTP cookie header for us, looking up an existing
-cookie is straightforward:
-
-FIXME.
-
- Here, FIXME is the name we chose for our session cookie.
-
-Setting the cookie header
-=========================
-
-MHD requires the user to provide the full cookie format string in order
-to set cookies. In order to generate a unique cookie, our example
-creates a random 64-character text string to be used as the value of
-the cookie:
-
-FIXME.
-
- Given this cookie value, we can then set the cookie header in our
-HTTP response as follows:
-
-FIXME.
-
-Remark: Session expiration
-==========================
-
-It is of course possible that clients stop their interaction with the
-server at any time. In order to avoid using too much storage, the
-server must thus discard inactive sessions at some point. Our example
-implements this by discarding inactive sessions after a certain amount
-of time. Alternatively, the implementation may limit the total number
-of active sessions. Which bounds are used for idle sessions or the
-total number of sessions obviously depends largely on the type of the
-application and available server resources.
-
-Example code
-============
-
-A sample application implementing a website with multiple forms (which
-are dynamically created using values from previous POST requests from
-the same session) is available as the example `sessions.c'.
-
- Note that the example uses a simple, $O(n)$ linked list traversal to
-look up sessions and to expire old sessions. Using a hash table and a
-heap would be more appropriate if a large number of concurrent sessions
-is expected.
-
-Remarks
-=======
-
-Naturally, it is quite conceivable to store session data in a database
-instead of in memory. Still, having mechanisms to expire data
-associated with long-time idle sessions (where the business process has
-still not finished) is likely a good idea.

-9 Adding a layer of security
-****************************
-
-We left the basic authentication chapter with the unsatisfactory
-conclusion that any traffic, including the credentials, could be
-intercepted by anyone between the browser client and the server.
-Protecting the data while it is sent over unsecured lines will be the
-goal of this chapter.
-
- Since version 0.4, the _MHD_ library includes support for encrypting
-the traffic by employing SSL/TSL. If _GNU libmicrohttpd_ has been
-configured to support these, encryption and decryption can be applied
-transparently on the data being sent, with only minimal changes to the
-actual source code of the example.
-
-Preparation
-===========
-
-First, a private key for the server will be generated. With this key,
-the server will later be able to authenticate itself to the
-client--preventing anyone else from stealing the password by faking its
-identity. The _OpenSSL_ suite, which is available on many operating
-systems, can generate such a key. For the scope of this tutorial, we
-will be content with a 1024 bit key:
-> openssl genrsa -out server.key 1024
- In addition to the key, a certificate describing the server in human
-readable tokens is also needed. This certificate will be attested with
-our aforementioned key. In this way, we obtain a self-signed
-certificate, valid for one year.
-
-> openssl req -days 365 -out server.pem -new -x509 -key server.key
- To avoid unnecessary error messages in the browser, the certificate
-needs to have a name that matches the _URI_, for example, "localhost"
-or the domain. If you plan to have a publicly reachable server, you
-will need to ask a trusted third party, called _Certificate Authority_,
-or _CA_, to attest the certificate for you. This way, any visitor can
-make sure the server's identity is real.
-
- Whether the server's certificate is signed by us or a third party,
-once it has been accepted by the client, both sides will be
-communicating over encrypted channels. From this point on, it is the
-client's turn to authenticate itself. But this has already been
-implemented in the basic authentication scheme.
-
-Changing the source code
-========================
-
-We merely have to extend the server program so that it loads the two
-files into memory,
-
-int
-main ()
-{
- struct MHD_Daemon *daemon;
- char *key_pem;
- char *cert_pem;
-
- key_pem = load_file (SERVERKEYFILE);
- cert_pem = load_file (SERVERCERTFILE);
-
- if ((key_pem == NULL) || (cert_pem == NULL))
- {
- printf ("The key/certificate files could not be read.\n");
- return 1;
- }
- and then we point the _MHD_ daemon to it upon initalization.
-
- daemon = MHD_start_daemon (MHD_USE_SELECT_INTERNALLY | MHD_USE_SSL,
- PORT, NULL, NULL,
- &answer_to_connection, NULL,
- MHD_OPTION_HTTPS_MEM_KEY, key_pem,
- MHD_OPTION_HTTPS_MEM_CERT, cert_pem,
- MHD_OPTION_END);
-
- if (NULL == daemon)
- {
- printf ("%s\n", cert_pem);
-
- free (key_pem);
- free (cert_pem);
-
- return 1;
- }
- The rest consists of little new besides some additional memory
-cleanups.
-
- getchar ();
-
- MHD_stop_daemon (daemon);
- free (key_pem);
- free (cert_pem);
-
- return 0;
-}
- The rather unexciting file loader can be found in the complete example
-`tlsauthentication.c'.
-
-Remarks
-=======
-
- * While the standard _HTTP_ port is 80, it is 443 for _HTTPS_. The
- common internet browsers assume standard _HTTP_ if they are asked
- to access other ports than these. Therefore, you will have to type
- `https://localhost:8888' explicitly when you test the example, or
- the browser will not know how to handle the answer properly.
-
- * The remaining weak point is the question how the server will be
- trusted initially. Either a _CA_ signs the certificate or the
- client obtains the key over secure means. Anyway, the clients have
- to be aware (or configured) that they should not accept
- certificates of unknown origin.
-
- * The introduced method of certificates makes it mandatory to set an
- expiration date--making it less feasible to hardcode certificates
- in embedded devices.
-
- * The cryptographic facilities consume memory space and computing
- time. For this reason, websites usually consists both of
- uncritically _HTTP_ parts and secured _HTTPS_.
-
-
-Client authentication
-=====================
-
-You can also use MHD to authenticate the client via SSL/TLS certificates
-(as an alternative to using the password-based Basic or Digest
-authentication). To do this, you will need to link your application
-against _gnutls_. Next, when you start the MHD daemon, you must
-specify the root CA that you're willing to trust:
- daemon = MHD_start_daemon (MHD_USE_SELECT_INTERNALLY | MHD_USE_SSL,
- PORT, NULL, NULL,
- &answer_to_connection, NULL,
- MHD_OPTION_HTTPS_MEM_KEY, key_pem,
- MHD_OPTION_HTTPS_MEM_CERT, cert_pem,
- MHD_OPTION_HTTPS_MEM_TRUST, root_ca_pem,
- MHD_OPTION_END);
-
- With this, you can then obtain client certificates for each session.
-In order to obtain the identity of the client, you first need to obtain
-the raw GnuTLS session handle from _MHD_ using
-`MHD_get_connection_info'.
-
-#include <gnutls/gnutls.h>
-#include <gnutls/x509.h>
-
-gnutls_session_t tls_session;
-union MHD_ConnectionInfo *ci;
-
-ci = MHD_get_connection_info (connection,
- MHD_CONNECTION_INFO_GNUTLS_SESSION);
-tls_session = ci->tls_session;
-
- You can then extract the client certificate:
-
-/**
- * Get the client's certificate
- *
- * @param tls_session the TLS session
- * @return NULL if no valid client certificate could be found, a pointer
- * to the certificate if found
- */
-static gnutls_x509_crt_t
-get_client_certificate (gnutls_session_t tls_session)
-{
- unsigned int listsize;
- const gnutls_datum_t * pcert;
- gnutls_certificate_status_t client_cert_status;
- gnutls_x509_crt_t client_cert;
-
- if (tls_session == NULL)
- return NULL;
- if (gnutls_certificate_verify_peers2(tls_session,
- &client_cert_status))
- return NULL;
- pcert = gnutls_certificate_get_peers(tls_session,
- &listsize);
- if ( (pcert == NULL) ||
- (listsize == 0))
- {
- fprintf (stderr,
- "Failed to retrieve client certificate chain\n");
- return NULL;
- }
- if (gnutls_x509_crt_init(&client_cert))
- {
- fprintf (stderr,
- "Failed to initialize client certificate\n");
- return NULL;
- }
- /* Note that by passing values between 0 and listsize here, you
- can get access to the CA's certs */
- if (gnutls_x509_crt_import(client_cert,
- &pcert[0],
- GNUTLS_X509_FMT_DER))
- {
- fprintf (stderr,
- "Failed to import client certificate\n");
- gnutls_x509_crt_deinit(client_cert);
- return NULL;
- }
- return client_cert;
-}
-
- Using the client certificate, you can then get the client's
-distinguished name and alternative names:
-
-/**
- * Get the distinguished name from the client's certificate
- *
- * @param client_cert the client certificate
- * @return NULL if no dn or certificate could be found, a pointer
- * to the dn if found
- */
-char *
-cert_auth_get_dn(gnutls_x509_crt_c client_cert)
-{
- char* buf;
- size_t lbuf;
-
- lbuf = 0;
- gnutls_x509_crt_get_dn(client_cert, NULL, &lbuf);
- buf = malloc(lbuf);
- if (buf == NULL)
- {
- fprintf (stderr,
- "Failed to allocate memory for certificate dn\n");
- return NULL;
- }
- gnutls_x509_crt_get_dn(client_cert, buf, &lbuf);
- return buf;
-}
-
-
-/**
- * Get the alternative name of specified type from the client's certificate
- *
- * @param client_cert the client certificate
- * @param nametype The requested name type
- * @param index The position of the alternative name if multiple names are
- * matching the requested type, 0 for the first matching name
- * @return NULL if no matching alternative name could be found, a pointer
- * to the alternative name if found
- */
-char *
-MHD_cert_auth_get_alt_name(gnutls_x509_crt_t client_cert,
- int nametype,
- unsigned int index)
-{
- char* buf;
- size_t lbuf;
- unsigned int seq;
- unsigned int subseq;
- unsigned int type;
- int result;
-
- subseq = 0;
- for (seq=0;;seq++)
- {
- lbuf = 0;
- result = gnutls_x509_crt_get_subject_alt_name2(client_cert, seq, NULL, &lbuf,
- &type, NULL);
- if (result == GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE)
- return NULL;
- if (nametype != (int) type)
- continue;
- if (subseq == index)
- break;
- subseq++;
- }
- buf = malloc(lbuf);
- if (buf == NULL)
- {
- fprintf (stderr,
- "Failed to allocate memory for certificate alt name\n");
- return NULL;
- }
- result = gnutls_x509_crt_get_subject_alt_name2(client_cert,
- seq,
- buf,
- &lbuf,
- NULL, NULL);
- if (result != nametype)
- {
- fprintf (stderr,
- "Unexpected return value from gnutls: %d\n",
- result);
- free (buf);
- return NULL;
- }
- return buf;
-}
-
- Finally, you should release the memory associated with the client
-certificate:
-
-gnutls_x509_crt_deinit (client_cert);
-
-Using TLS Server Name Indication (SNI)
-======================================
-
-SNI enables hosting multiple domains under one IP address with TLS. So
-SNI is the TLS-equivalent of virtual hosting. To use SNI with MHD, you
-need at least GnuTLS 3.0. The main change compared to the simple
-hosting of one domain is that you need to provide a callback instead of
-the key and certificate. For example, when you start the MHD daemon,
-you could do this:
- daemon = MHD_start_daemon (MHD_USE_SELECT_INTERNALLY | MHD_USE_SSL,
- PORT, NULL, NULL,
- &answer_to_connection, NULL,
- MHD_OPTION_HTTPS_CERT_CALLBACK, &sni_callback,
- MHD_OPTION_END);
- Here, `sni_callback' is the name of a function that you will have to
-implement to retrieve the X.509 certificate for an incoming connection.
-The callback has type `gnutls_certificate_retrieve_function2' and is
-documented in the GnuTLS API for the
-`gnutls_certificate_set_retrieve_function2' as follows:
-
- -- Function Pointer: int *gnutls_certificate_retrieve_function2
- (gnutls_session_t, const gnutls_datum_t* req_ca_dn, int
- nreqs, const gnutls_pk_algorithm_t* pk_algos, int
- pk_algos_length, gnutls_pcert_st** pcert, unsigned int
- *pcert_length, gnutls_privkey_t * pkey)
- REQ_CA_CERT
- is only used in X.509 certificates. Contains a list with the
- CA names that the server considers trusted. Normally we
- should send a certificate that is signed by one of these CAs.
- These names are DER encoded. To get a more meaningful value
- use the function `gnutls_x509_rdn_get()'.
-
- PK_ALGOS
- contains a list with server’s acceptable signature
- algorithms. The certificate returned should support the
- server’s given algorithms.
-
- PCERT
- should contain a single certificate and public or a list of
- them.
-
- PCERT_LENGTH
- is the size of the previous list.
-
- PKEY
- is the private key.
-
- A possible implementation of this callback would look like this:
-
-struct Hosts
-{
- struct Hosts *next;
- const char *hostname;
- gnutls_pcert_st pcrt;
- gnutls_privkey_t key;
-};
-
-static struct Hosts *hosts;
-
-int
-sni_callback (gnutls_session_t session,
- const gnutls_datum_t* req_ca_dn,
- int nreqs,
- const gnutls_pk_algorithm_t* pk_algos,
- int pk_algos_length,
- gnutls_pcert_st** pcert,
- unsigned int *pcert_length,
- gnutls_privkey_t * pkey)
-{
- char name[256];
- size_t name_len;
- struct Hosts *host;
- unsigned int type;
-
- name_len = sizeof (name);
- if (GNUTLS_E_SUCCESS !=
- gnutls_server_name_get (session,
- name,
- &name_len,
- &type,
- 0 /* index */))
- return -1;
- for (host = hosts; NULL != host; host = host->next)
- if (0 == strncmp (name, host->hostname, name_len))
- break;
- if (NULL == host)
- {
- fprintf (stderr,
- "Need certificate for %.*s\n",
- (int) name_len,
- name);
- return -1;
- }
- fprintf (stderr,
- "Returning certificate for %.*s\n",
- (int) name_len,
- name);
- *pkey = host->key;
- *pcert_length = 1;
- *pcert = &host->pcrt;
- return 0;
-}
-
- Note that MHD cannot offer passing a closure or any other additional
-information to this callback, as the GnuTLS API unfortunately does not
-permit this at this point.
-
- The `hosts' list can be initialized by loading the private keys and
-X.509 certificats from disk as follows:
-
-static void
-load_keys(const char *hostname,
- const char *CERT_FILE,
- const char *KEY_FILE)
-{
- int ret;
- gnutls_datum_t data;
- struct Hosts *host;
-
- host = malloc (sizeof (struct Hosts));
- host->hostname = hostname;
- host->next = hosts;
- hosts = host;
-
- ret = gnutls_load_file (CERT_FILE, &data);
- if (ret < 0)
- {
- fprintf (stderr,
- "*** Error loading certificate file %s.\n",
- CERT_FILE);
- exit(1);
- }
- ret =
- gnutls_pcert_import_x509_raw (&host->pcrt, &data, GNUTLS_X509_FMT_PEM,
- 0);
- if (ret < 0)
- {
- fprintf(stderr,
- "*** Error loading certificate file: %s\n",
- gnutls_strerror (ret));
- exit(1);
- }
- gnutls_free (data.data);
-
- ret = gnutls_load_file (KEY_FILE, &data);
- if (ret < 0)
- {
- fprintf (stderr,
- "*** Error loading key file %s.\n",
- KEY_FILE);
- exit(1);
- }
-
- gnutls_privkey_init (&host->key);
- ret =
- gnutls_privkey_import_x509_raw (host->key,
- &data, GNUTLS_X509_FMT_PEM,
- NULL, 0);
- if (ret < 0)
- {
- fprintf (stderr,
- "*** Error loading key file: %s\n",
- gnutls_strerror (ret));
- exit(1);
- }
- gnutls_free (data.data);
-}
-
- The code above was largely lifted from GnuTLS. You can find other
-methods for initializing certificates and keys in the GnuTLS manual and
-source code.

-*****************************************
-
- Version 1.3, 3 November 2008
-
- Copyright (C) 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.
- `http://fsf.org/'
-
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
- 0. PREAMBLE
-
- The purpose of this License is to make a manual, textbook, or other
- functional and useful document "free" in the sense of freedom: to
- assure everyone the effective freedom to copy and redistribute it,
- with or without modifying it, either commercially or
- noncommercially. Secondarily, this License preserves for the
- author and publisher a way to get credit for their work, while not
- being considered responsible for modifications made by others.
-
- This License is a kind of "copyleft", which means that derivative
- works of the document must themselves be free in the same sense.
- It complements the GNU General Public License, which is a copyleft
- license designed for free software.
-
- We have designed this License in order to use it for manuals for
- free software, because free software needs free documentation: a
- free program should come with manuals providing the same freedoms
- that the software does. But this License is not limited to
- software manuals; it can be used for any textual work, regardless
- of subject matter or whether it is published as a printed book.
- We recommend this License principally for works whose purpose is
- instruction or reference.
-
- 1. APPLICABILITY AND DEFINITIONS
-
- This License applies to any manual or other work, in any medium,
- that contains a notice placed by the copyright holder saying it
- can be distributed under the terms of this License. Such a notice
- grants a world-wide, royalty-free license, unlimited in duration,
- to use that work under the conditions stated herein. The
- "Document", below, refers to any such manual or work. Any member
- of the public is a licensee, and is addressed as "you". You
- accept the license if you copy, modify or distribute the work in a
- way requiring permission under copyright law.
-
- A "Modified Version" of the Document means any work containing the
- Document or a portion of it, either copied verbatim, or with
- modifications and/or translated into another language.
-
- A "Secondary Section" is a named appendix or a front-matter section
- of the Document that deals exclusively with the relationship of the
- publishers or authors of the Document to the Document's overall
- subject (or to related matters) and contains nothing that could
- fall directly within that overall subject. (Thus, if the Document
- is in part a textbook of mathematics, a Secondary Section may not
- explain any mathematics.) The relationship could be a matter of
- historical connection with the subject or with related matters, or
- of legal, commercial, philosophical, ethical or political position
- regarding them.
-
- The "Invariant Sections" are certain Secondary Sections whose
- titles are designated, as being those of Invariant Sections, in
- the notice that says that the Document is released under this
- License. If a section does not fit the above definition of
- Secondary then it is not allowed to be designated as Invariant.
- The Document may contain zero Invariant Sections. If the Document
- does not identify any Invariant Sections then there are none.
-
- The "Cover Texts" are certain short passages of text that are
- listed, as Front-Cover Texts or Back-Cover Texts, in the notice
- that says that the Document is released under this License. A
- Front-Cover Text may be at most 5 words, and a Back-Cover Text may
- be at most 25 words.
-
- A "Transparent" copy of the Document means a machine-readable copy,
- represented in a format whose specification is available to the
- general public, that is suitable for revising the document
- straightforwardly with generic text editors or (for images
- composed of pixels) generic paint programs or (for drawings) some
- widely available drawing editor, and that is suitable for input to
- text formatters or for automatic translation to a variety of
- formats suitable for input to text formatters. A copy made in an
- otherwise Transparent file format whose markup, or absence of
- markup, has been arranged to thwart or discourage subsequent
- modification by readers is not Transparent. An image format is
- not Transparent if used for any substantial amount of text. A
- copy that is not "Transparent" is called "Opaque".
-
- Examples of suitable formats for Transparent copies include plain
- ASCII without markup, Texinfo input format, LaTeX input format,
- SGML or XML using a publicly available DTD, and
- standard-conforming simple HTML, PostScript or PDF designed for
- human modification. Examples of transparent image formats include
- PNG, XCF and JPG. Opaque formats include proprietary formats that
- can be read and edited only by proprietary word processors, SGML or
- XML for which the DTD and/or processing tools are not generally
- available, and the machine-generated HTML, PostScript or PDF
- produced by some word processors for output purposes only.
-
- The "Title Page" means, for a printed book, the title page itself,
- plus such following pages as are needed to hold, legibly, the
- material this License requires to appear in the title page. For
- works in formats which do not have any title page as such, "Title
- Page" means the text near the most prominent appearance of the
- work's title, preceding the beginning of the body of the text.
-
- The "publisher" means any person or entity that distributes copies
- of the Document to the public.
-
- A section "Entitled XYZ" means a named subunit of the Document
- whose title either is precisely XYZ or contains XYZ in parentheses
- following text that translates XYZ in another language. (Here XYZ
- stands for a specific section name mentioned below, such as
- "Acknowledgements", "Dedications", "Endorsements", or "History".)
- To "Preserve the Title" of such a section when you modify the
- Document means that it remains a section "Entitled XYZ" according
- to this definition.
-
- The Document may include Warranty Disclaimers next to the notice
- which states that this License applies to the Document. These
- Warranty Disclaimers are considered to be included by reference in
- this License, but only as regards disclaiming warranties: any other
- implication that these Warranty Disclaimers may have is void and
- has no effect on the meaning of this License.
-
- 2. VERBATIM COPYING
-
- You may copy and distribute the Document in any medium, either
- commercially or noncommercially, provided that this License, the
- copyright notices, and the license notice saying this License
- applies to the Document are reproduced in all copies, and that you
- add no other conditions whatsoever to those of this License. You
- may not use technical measures to obstruct or control the reading
- or further copying of the copies you make or distribute. However,
- you may accept compensation in exchange for copies. If you
- distribute a large enough number of copies you must also follow
- the conditions in section 3.
-
- You may also lend copies, under the same conditions stated above,
- and you may publicly display copies.
-
- 3. COPYING IN QUANTITY
-
- If you publish printed copies (or copies in media that commonly
- have printed covers) of the Document, numbering more than 100, and
- the Document's license notice requires Cover Texts, you must
- enclose the copies in covers that carry, clearly and legibly, all
- these Cover Texts: Front-Cover Texts on the front cover, and
- Back-Cover Texts on the back cover. Both covers must also clearly
- and legibly identify you as the publisher of these copies. The
- front cover must present the full title with all words of the
- title equally prominent and visible. You may add other material
- on the covers in addition. Copying with changes limited to the
- covers, as long as they preserve the title of the Document and
- satisfy these conditions, can be treated as verbatim copying in
- other respects.
-
- If the required texts for either cover are too voluminous to fit
- legibly, you should put the first ones listed (as many as fit
- reasonably) on the actual cover, and continue the rest onto
- adjacent pages.
-
- If you publish or distribute Opaque copies of the Document
- numbering more than 100, you must either include a
- machine-readable Transparent copy along with each Opaque copy, or
- state in or with each Opaque copy a computer-network location from
- which the general network-using public has access to download
- using public-standard network protocols a complete Transparent
- copy of the Document, free of added material. If you use the
- latter option, you must take reasonably prudent steps, when you
- begin distribution of Opaque copies in quantity, to ensure that
- this Transparent copy will remain thus accessible at the stated
- location until at least one year after the last time you
- distribute an Opaque copy (directly or through your agents or
- retailers) of that edition to the public.
-
- It is requested, but not required, that you contact the authors of
- the Document well before redistributing any large number of
- copies, to give them a chance to provide you with an updated
- version of the Document.
-
- 4. MODIFICATIONS
-
- You may copy and distribute a Modified Version of the Document
- under the conditions of sections 2 and 3 above, provided that you
- release the Modified Version under precisely this License, with
- the Modified Version filling the role of the Document, thus
- licensing distribution and modification of the Modified Version to
- whoever possesses a copy of it. In addition, you must do these
- things in the Modified Version:
-
- A. Use in the Title Page (and on the covers, if any) a title
- distinct from that of the Document, and from those of
- previous versions (which should, if there were any, be listed
- in the History section of the Document). You may use the
- same title as a previous version if the original publisher of
- that version gives permission.
-
- B. List on the Title Page, as authors, one or more persons or
- entities responsible for authorship of the modifications in
- the Modified Version, together with at least five of the
- principal authors of the Document (all of its principal
- authors, if it has fewer than five), unless they release you
- from this requirement.
-
- C. State on the Title page the name of the publisher of the
- Modified Version, as the publisher.
-
- D. Preserve all the copyright notices of the Document.
-
- E. Add an appropriate copyright notice for your modifications
- adjacent to the other copyright notices.
-
- F. Include, immediately after the copyright notices, a license
- notice giving the public permission to use the Modified
- Version under the terms of this License, in the form shown in
- the Addendum below.
-
- G. Preserve in that license notice the full lists of Invariant
- Sections and required Cover Texts given in the Document's
- license notice.
-
- H. Include an unaltered copy of this License.
-
- I. Preserve the section Entitled "History", Preserve its Title,
- and add to it an item stating at least the title, year, new
- authors, and publisher of the Modified Version as given on
- the Title Page. If there is no section Entitled "History" in
- the Document, create one stating the title, year, authors,
- and publisher of the Document as given on its Title Page,
- then add an item describing the Modified Version as stated in
- the previous sentence.
-
- J. Preserve the network location, if any, given in the Document
- for public access to a Transparent copy of the Document, and
- likewise the network locations given in the Document for
- previous versions it was based on. These may be placed in
- the "History" section. You may omit a network location for a
- work that was published at least four years before the
- Document itself, or if the original publisher of the version
- it refers to gives permission.
-
- K. For any section Entitled "Acknowledgements" or "Dedications",
- Preserve the Title of the section, and preserve in the
- section all the substance and tone of each of the contributor
- acknowledgements and/or dedications given therein.
-
- L. Preserve all the Invariant Sections of the Document,
- unaltered in their text and in their titles. Section numbers
- or the equivalent are not considered part of the section
- titles.
-
- M. Delete any section Entitled "Endorsements". Such a section
- may not be included in the Modified Version.
-
- N. Do not retitle any existing section to be Entitled
- "Endorsements" or to conflict in title with any Invariant
- Section.
-
- O. Preserve any Warranty Disclaimers.
-
- If the Modified Version includes new front-matter sections or
- appendices that qualify as Secondary Sections and contain no
- material copied from the Document, you may at your option
- designate some or all of these sections as invariant. To do this,
- add their titles to the list of Invariant Sections in the Modified
- Version's license notice. These titles must be distinct from any
- other section titles.
-
- You may add a section Entitled "Endorsements", provided it contains
- nothing but endorsements of your Modified Version by various
- parties--for example, statements of peer review or that the text
- has been approved by an organization as the authoritative
- definition of a standard.
-
- You may add a passage of up to five words as a Front-Cover Text,
- and a passage of up to 25 words as a Back-Cover Text, to the end
- of the list of Cover Texts in the Modified Version. Only one
- passage of Front-Cover Text and one of Back-Cover Text may be
- added by (or through arrangements made by) any one entity. If the
- Document already includes a cover text for the same cover,
- previously added by you or by arrangement made by the same entity
- you are acting on behalf of, you may not add another; but you may
- replace the old one, on explicit permission from the previous
- publisher that added the old one.
-
- The author(s) and publisher(s) of the Document do not by this
- License give permission to use their names for publicity for or to
- assert or imply endorsement of any Modified Version.
-
- 5. COMBINING DOCUMENTS
-
- You may combine the Document with other documents released under
- this License, under the terms defined in section 4 above for
- modified versions, provided that you include in the combination
- all of the Invariant Sections of all of the original documents,
- unmodified, and list them all as Invariant Sections of your
- combined work in its license notice, and that you preserve all
- their Warranty Disclaimers.
-
- The combined work need only contain one copy of this License, and
- multiple identical Invariant Sections may be replaced with a single
- copy. If there are multiple Invariant Sections with the same name
- but different contents, make the title of each such section unique
- by adding at the end of it, in parentheses, the name of the
- original author or publisher of that section if known, or else a
- unique number. Make the same adjustment to the section titles in
- the list of Invariant Sections in the license notice of the
- combined work.
-
- In the combination, you must combine any sections Entitled
- "History" in the various original documents, forming one section
- Entitled "History"; likewise combine any sections Entitled
- "Acknowledgements", and any sections Entitled "Dedications". You
- must delete all sections Entitled "Endorsements."
-
- 6. COLLECTIONS OF DOCUMENTS
-
- You may make a collection consisting of the Document and other
- documents released under this License, and replace the individual
- copies of this License in the various documents with a single copy
- that is included in the collection, provided that you follow the
- rules of this License for verbatim copying of each of the
- documents in all other respects.
-
- You may extract a single document from such a collection, and
- distribute it individually under this License, provided you insert
- a copy of this License into the extracted document, and follow
- this License in all other respects regarding verbatim copying of
- that document.
-
- 7. AGGREGATION WITH INDEPENDENT WORKS
-
- A compilation of the Document or its derivatives with other
- separate and independent documents or works, in or on a volume of
- a storage or distribution medium, is called an "aggregate" if the
- copyright resulting from the compilation is not used to limit the
- legal rights of the compilation's users beyond what the individual
- works permit. When the Document is included in an aggregate, this
- License does not apply to the other works in the aggregate which
- are not themselves derivative works of the Document.
-
- If the Cover Text requirement of section 3 is applicable to these
- copies of the Document, then if the Document is less than one half
- of the entire aggregate, the Document's Cover Texts may be placed
- on covers that bracket the Document within the aggregate, or the
- electronic equivalent of covers if the Document is in electronic
- form. Otherwise they must appear on printed covers that bracket
- the whole aggregate.
-
- 8. TRANSLATION
-
- Translation is considered a kind of modification, so you may
- distribute translations of the Document under the terms of section
- 4. Replacing Invariant Sections with translations requires special
- permission from their copyright holders, but you may include
- translations of some or all Invariant Sections in addition to the
- original versions of these Invariant Sections. You may include a
- translation of this License, and all the license notices in the
- Document, and any Warranty Disclaimers, provided that you also
- include the original English version of this License and the
- original versions of those notices and disclaimers. In case of a
- disagreement between the translation and the original version of
- this License or a notice or disclaimer, the original version will
- prevail.
-
- If a section in the Document is Entitled "Acknowledgements",
- "Dedications", or "History", the requirement (section 4) to
- Preserve its Title (section 1) will typically require changing the
- actual title.
-
- 9. TERMINATION
-
- You may not copy, modify, sublicense, or distribute the Document
- except as expressly provided under this License. Any attempt
- otherwise to copy, modify, sublicense, or distribute it is void,
- and will automatically terminate your rights under this License.
-
- However, if you cease all violation of this License, then your
- license from a particular copyright holder is reinstated (a)
- provisionally, unless and until the copyright holder explicitly
- and finally terminates your license, and (b) permanently, if the
- copyright holder fails to notify you of the violation by some
- reasonable means prior to 60 days after the cessation.
-
- Moreover, your license from a particular copyright holder is
- reinstated permanently if the copyright holder notifies you of the
- violation by some reasonable means, this is the first time you have
- received notice of violation of this License (for any work) from
- that copyright holder, and you cure the violation prior to 30 days
- after your receipt of the notice.
-
- Termination of your rights under this section does not terminate
- the licenses of parties who have received copies or rights from
- you under this License. If your rights have been terminated and
- not permanently reinstated, receipt of a copy of some or all of
- the same material does not give you any rights to use it.
-
- 10. FUTURE REVISIONS OF THIS LICENSE
-
- The Free Software Foundation may publish new, revised versions of
- the GNU Free Documentation License from time to time. Such new
- versions will be similar in spirit to the present version, but may
- differ in detail to address new problems or concerns. See
- `http://www.gnu.org/copyleft/'.
-
- Each version of the License is given a distinguishing version
- number. If the Document specifies that a particular numbered
- version of this License "or any later version" applies to it, you
- have the option of following the terms and conditions either of
- that specified version or of any later version that has been
- published (not as a draft) by the Free Software Foundation. If
- the Document does not specify a version number of this License,
- you may choose any version ever published (not as a draft) by the
- Free Software Foundation. If the Document specifies that a proxy
- can decide which future versions of this License can be used, that
- proxy's public statement of acceptance of a version permanently
- authorizes you to choose that version for the Document.
-
- 11. RELICENSING
-
- "Massive Multiauthor Collaboration Site" (or "MMC Site") means any
- World Wide Web server that publishes copyrightable works and also
- provides prominent facilities for anybody to edit those works. A
- public wiki that anybody can edit is an example of such a server.
- A "Massive Multiauthor Collaboration" (or "MMC") contained in the
- site means any set of copyrightable works thus published on the MMC
- site.
-
- "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
- license published by Creative Commons Corporation, a not-for-profit
- corporation with a principal place of business in San Francisco,
- California, as well as future copyleft versions of that license
- published by that same organization.
-
- "Incorporate" means to publish or republish a Document, in whole or
- in part, as part of another Document.
-
- An MMC is "eligible for relicensing" if it is licensed under this
- License, and if all works that were first published under this
- License somewhere other than this MMC, and subsequently
- incorporated in whole or in part into the MMC, (1) had no cover
- texts or invariant sections, and (2) were thus incorporated prior
- to November 1, 2008.
-
- The operator of an MMC Site may republish an MMC contained in the
- site under CC-BY-SA on the same site at any time before August 1,
- 2009, provided the MMC is eligible for relicensing.
-
-
-ADDENDUM: How to use this License for your documents
-====================================================
-
-To use this License in a document you have written, include a copy of
-the License in the document and put the following copyright and license
-notices just after the title page:
-
- Copyright (C) YEAR YOUR NAME.
- Permission is granted to copy, distribute and/or modify this document
- under the terms of the GNU Free Documentation License, Version 1.3
- or any later version published by the Free Software Foundation;
- with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
- Texts. A copy of the license is included in the section entitled ``GNU
- Free Documentation License''.
-
- If you have Invariant Sections, Front-Cover Texts and Back-Cover
-Texts, replace the "with...Texts." line with this:
-
- with the Invariant Sections being LIST THEIR TITLES, with
- the Front-Cover Texts being LIST, and with the Back-Cover Texts
- being LIST.
-
- If you have Invariant Sections without Cover Texts, or some other
-combination of the three, merge those two alternatives to suit the
-situation.
-
- If your document contains nontrivial examples of program code, we
-recommend releasing these examples in parallel under your choice of
-free software license, such as the GNU General Public License, to
-permit their use in free software.

+@section Creating a response for protocol upgrades
+@cindex WebSockets
+@cindex Upgrade
+@cindex HTTP2
+@cindex RFC2817
+
+With RFC 2817 a mechanism to switch protocols within HTTP was
+introduced. Here, a client sends a request with a ``Connection:
+Upgrade'' header. The server responds with a ``101 Switching
+Protocols'' response header, after which the two parties begin to
+speak a different (non-HTTP) protocol over the TCP connection.
+
+This mechanism is used for upgrading HTTP 1.1 connections to HTTP2 or
+HTTPS, as well as for implementing WebSockets. Which protocol
+upgrade is performed is negotiated between server and client in
+additional headers, in particular the ``Upgrade'' header.
+
+MHD supports switching protocols using this mechanism only if the
+@code{MHD_ALLOW_SUSPEND_RESUME} flag has been set when starting
+the daemon. If this flag has been set, applications can upgrade
+a connection by queueing a response (using the
+@code{MHD_HTTP_SWITCHING_PROTOCOLS} status code) which must
+have been created with the following function:
+
+
+@deftypefun enum MHD_Result MHD_create_response_for_upgrade (MHD_UpgradeHandler upgrade_handler, void *upgrade_handler_cls)
+Create a response suitable for switching protocols. Returns @code{MHD_YES} on success. @code{upgrade_handler} must not be @code{NULL}.
+
+When creating this type of response, the ``Connection: Upgrade''
+header will be set automatically for you. MHD requires that you
+additionally set an ``Upgrade:'' header. The ``Upgrade'' header
+must simply exist, the specific value is completely up to the
+application.
+
+@end deftypefun
+
+The @code{upgrade_handler} argument to the above has the following type:
+
+
+@deftypefn {Function Pointer} void {*MHD_UpgradeHandler} (void *cls, struct MHD_Connection *connection, const char *extra_in, size_t extra_in_size, MHD_socket sock, struct MHD_UpgradeResponseHandle *urh)
+This function will be called once MHD has transmitted the header of the response to the connection that is being upgraded. At this point, the application is expected to take over the socket @code{sock} and speak the non-HTTP protocol to which the connection was upgraded. MHD will no longer use the socket; this includes handling timeouts. The application must call @code{MHD_upgrade_action} with an upgrade action of @code{MHD_UPGRADE_ACTION_CLOSE} when it is done processing the connection to close the socket. The application must not call @code{MHD_stop_daemon} on the respective daemon as long as it is still handling the connection. The arguments given to the @code{upgrade_handler} have the following meaning:

+number of bytes in @code{extra_in}
+
+@item sock
+the socket which the application can now use directly for some bi-directional communication with the client. The application can henceforth use @code{recv()} and @code{send()} or @code{read()} and @code{write()} system calls on the socket. However, @code{ioctl()} and @code{setsockopt()} functions will not work as expected when using HTTPS. Such operations may be supported in the future via @code{MHD_upgrade_action}. Most importantly, the application must never call @code{close()} on this socket. Closing the socket must be done using @code{MHD_upgrade_action}. However, while close is forbidden, the application may call @code{shutdown()} on the socket.

+@code{MHD_WEBSOCKET_CLOSEREASON_NO_REASON} (or just 0) then
+no reason is encoded.
+
+@item reason_utf8
+An UTF-8 encoded text reason why the connection is closed.
+This may be @code{NULL} if @code{reason_utf8_len} is 0.
+This must be @code{NULL} if @code{reason_code} equals to zero
+(@code{MHD_WEBSOCKET_CLOSEREASON_NO_REASON}).

+@item reason_utf8_len
+length of the UTF-8 encoded text reason in bytes.
+This may not exceed 123 bytes.
+
+@item frame
+pointer to a variable, which receives a buffer with the encoded close frame.
+Must not be @code{NULL}.
+The buffer contains what you typically send via @code{send()} to the recipient.
+If no encoded data is available the variable receives @code{NULL}.

-% @multitable macros
-% Amy Hendrickson, 8/18/94, 3/6/96
-%
-% @multitable ... @end multitable will make as many columns as desired.
-% Contents of each column will wrap at width given in preamble. Width
-% can be specified either with sample text given in a template line,
-% or in percent of \hsize, the current width of text on page.
-
-% Table can continue over pages but will only break between lines.
-
-% To make preamble:
-%
-% Either define widths of columns in terms of percent of \hsize:
-% @multitable @columnfractions .25 .3 .45
-% @item ...
-%
-% Numbers following @columnfractions are the percent of the total
-% current hsize to be used for each column. You may use as many
-% columns as desired.
-
-
-% Or use a template:
-% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
-% @item ...
-% using the widest term desired in each column.
-
-% Each new table line starts with @item, each subsequent new column
-% starts with @tab. Empty columns may be produced by supplying @tab's
-% with nothing between them for as many times as empty columns are needed,
-% ie, @tab@tab@tab will produce two empty columns.
-
-% @item, @tab do not need to be on their own lines, but it will not hurt
-% if they are.
-
-% Sample multitable:
-
-% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
-% @item first col stuff @tab second col stuff @tab third col
-% @item
-% first col stuff
-% @tab
-% second col stuff
-% @tab
-% third col
-% @item first col stuff @tab second col stuff
-% @tab Many paragraphs of text may be used in any column.
-%
-% They will wrap at the width determined by the template.
-% @item@tab@tab This will be in third column.
-% @end multitable
-
-% Default dimensions may be reset by user.
-% @multitableparskip is vertical space between paragraphs in table.
-% @multitableparindent is paragraph indent in table.
-% @multitablecolmargin is horizontal space to be left between columns.
-% @multitablelinespace is space to leave between table items, baseline
-% to baseline.

+# AX_APPEND_LINK_FLAGS([FLAG1 FLAG2 ...], [FLAGS-VARIABLE], [EXTRA-FLAGS], [INPUT])
+#
+# DESCRIPTION
+#
+# For every FLAG1, FLAG2 it is checked whether the linker works with the
+# flag. If it does, the flag is added FLAGS-VARIABLE
+#
+# If FLAGS-VARIABLE is not specified, the linker's flags (LDFLAGS) is
+# used. During the check the flag is always added to the linker's flags.
+#
+# If EXTRA-FLAGS is defined, it is added to the linker's default flags
+# when the check is done. The check is thus made with the flags: "LDFLAGS
+# EXTRA-FLAGS FLAG". This can for example be used to force the linker to
+# issue an error when a bad flag is given.
+#
+# INPUT gives an alternative input source to AC_COMPILE_IFELSE.
+#
+# NOTE: This macro depends on the AX_APPEND_FLAG and AX_CHECK_LINK_FLAG.

-# DESCRIPTION
-#
-# Look for OpenSSL in a number of default spots, or in a user-selected

-#
-# OPENSSL_INCLUDES to the include directives required

#
-# Attempt to count the number of processors present on the machine. If the

+# Attempt to count the number of logical processor cores (including
+# virtual and HT cores) currently available to use on the machine and

#
-# The value is placed in the CPU_COUNT variable.
+# On successful detection, ACTION-IF-DETECTED is executed if present. If
+# the detection fails, then ACTION-IF-NOT-DETECTED is triggered. The
+# default ACTION-IF-NOT-DETECTED is to set CPU_COUNT to 1.

+
+ Suppress extern inline with HP-UX cc, as it appears to be broken; see
+ <https://lists.gnu.org/r/bug-texinfo/2013-02/msg00030.html>.
+
+ Suppress extern inline with Sun C in standards-conformance mode, as it
+ mishandles inline functions that call each other. E.g., for 'inline void f
+ (void) { } inline void g (void) { f (); }', c99 incorrectly complains
+ 'reference to static identifier "f" in extern inline function'.
+ This bug was observed with Sun C 5.12 SunOS_i386 2011/11/16.
+
+ Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
+ on configurations that mistakenly use 'static inline' to implement
+ functions or macros in standard C headers like <ctype.h>. For example,
+ if isdigit is mistakenly implemented via a static inline function,
+ a program containing an extern inline function that calls isdigit
+ may not work since the C standard prohibits extern inline functions
+ from calling static functions (ISO C 99 section 6.7.4.(3).
+ This bug is known to occur on:
+
+ OS X 10.8 and earlier; see:
+ https://lists.gnu.org/r/bug-gnulib/2012-12/msg00023.html
+
+ DragonFly; see
+ http://muscles.dragonflybsd.org/bulk/clang-master-potential/20141111_102002/logs/ah-tty-0.3.12.log
+
+ FreeBSD; see:
+ https://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html
+
+ OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and
+ for clang but remains for g++; see <https://trac.macports.org/ticket/41033>.
+ Assume DragonFly and FreeBSD will be similar.
+

-
-# These exist entirely to fool aclocal when bootstrapping libtool.
-#
-# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
-# which have later been changed to m4_define as they aren't part of the
-# exported API, or moved to Autoconf or Automake where they belong.
-#
-# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
-# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
-# using a macro with the same name in our local m4/libtool.m4 it'll
-# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
-# and doesn't know about Autoconf macros at all.)
-#
-# So we provide this file, which has a silly filename so it's always
-# included after everything else. This provides aclocal with the
-# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
-# because those macros already exist, or will be overwritten later.
-# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
-#
-# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
-# Yes, that means every name once taken will need to remain here until
-# we give up compatibility with versions before 1.7, at which point
-# we need to keep only those names which we still refer to.
-
-# This is to help aclocal find these macros, as it can't see m4_define.

+#
+# DESCRIPTION
+#
+# This macro checks for presence of specific function by including
+# specified headers and compiling and linking CHECK_CODE.
+# This checks both declaration and presence in library.
+# If function is available then macro HAVE_function_name (the name
+# of the function convetedd to all uppercase characters) is defined
+# automatically.
+# Unlike AC_CHECK_FUNCS macro, this macro do not produce false
+# negative result if function is declared with specific calling
+# conventions like __stdcall' or attribute like
+# __attribute__((__dllimport__)) and linker failing to build test
+# program due to the different calling conventions.
+# By using definition from provided headers, this macro ensures that
+# correct calling convention is used for detection.
+#
+# Example usage:
+#
+# MHD_CHECK_FUNC([memmem],
+# [[#include <string.h>]],
+# [const void *ptr = memmem("aa", 2, "a", 1); (void)ptr;],
+# [var_use_memmem='yes'], [var_use_memmem='no'])

+# DESCRIPTION
+#
+# This macro checks whether the specific compiler flags are supported.
+# The flags are checked one-by-one. The checking is stopped when the first
+# supported flag found.
+# The checks are performing by appending FLAGx-TO-TEST to the value of
+# VARIABLE-TO-EXTEND (CFLAGS if not specified), then prepending result to
+# CFLAGS (unless VARIABLE-TO-EXTEND is CFLAGS), and then performing compile
+# and link test. If test succeed without warnings, then the flag is added to
+# VARIABLE-TO-EXTEND and next flags are not checked. If compile-link cycle
+# cannot be performed without warning with all tested flags, no flag is
+# added to the VARIABLE-TO-EXTEND.
+#
+# Example usage:
+#
+# MHD_CHECK_CC_CFLAG([additional_CFLAGS],
+# [-ggdb3], [-g3], [-ggdb], [-g])
+#
+# Note: Unlike others MHD_CHECK_*CC_CFLAG* macro, this macro uses another

+# cannot be performed without warning with all tested flags, no flag is
+# added to the VARIABLE-TO-EXTEND.
+# If any suitable flag is found, ACTION-IF-FOUND is executed otherwise

+#
+# DESCRIPTION
+#
+# This macro checks for presence of specific function by including
+# specified headers and compiling and linking CHECK_CODE.
+# This checks both the declaration and the presence in library.
+# If declaration is not found in headers then libraries are not
+# checked.
+# LIBS_TO_CHECK is whitespace-separated list of libraries to check.
+# The macro first tries to link without any library, and if it fails
+# the libraries are checked one by one.
+# The required library (if any) prepended to VAR_TO_PREPEND_LIB (or
+# to the LIBS variable if VAR_TO_APPEND_LIB is not specified).
+# By using definition from provided headers, this macro ensures that
+# correct calling convention is used for detection.
+#
+# Example usage:
+#
+# MHD_FIND_LIB([clock_gettime],
+# [[#include <time.h>]],
+# [[struct timespec tp;
+# if (0 > clock_gettime(CLOCK_REALTIME, &tp)) return 3;]],
+# [rt],
+# [var_use_gettime='yes'],[var_use_gettime='no'])
+#
+# Defined cache variable used in the check so if any test will not
+# work correctly on some platform, a user may simply fix it by giving
+# cache variable in configure parameters, for example:
+#
+# ./configure mhd_cv_find_clock_gettime=no
+#
+# This simplifies building from source on exotic platforms as patching
+# of configure.ac is not required to change results of tests.

+# SYNOPSIS
+#
+# MHD_SYS_EXT([VAR-ADD-CPPFLAGS])
+#
+# DESCRIPTION
+#
+# This macro checks system headers and add defines that enable maximum
+# number of exposed system interfaces. Macro verifies that added defines
+# will not break basic headers, some defines are also checked against
+# real recognition by headers.
+# If VAR-ADD-CPPFLAGS is specified, defines will be added to this variable
+# in form suitable for CPPFLAGS. Otherwise defines will be added to
+# configuration header (usually 'config.h').
+#
+# Example usage:
+#
+# MHD_SYS_EXT
+#
+# or
+#
+# MHD_SYS_EXT([CPPFLAGS])
+#
+# Macro is not enforced to be called before AC_COMPILE_IFELSE, but it
+# advisable to call macro before any compile and header tests since
+# additional defines can change results of those tests.
+#
+# Defined in command line macros are always honored and cache variables
+# used in all checks so if any test will not work correctly on some
+# platform, user may simply fix it by giving correct defines in CPPFLAGS
+# or by giving cache variable in configure parameters, for example:
+#
+# ./configure CPPFLAGS='-D_XOPEN_SOURCE=1 -D_XOPEN_SOURCE_EXTENDED'
+#
+# or
+#
+# ./configure mhd_cv_define__xopen_source_sevenh_works=no
+#
+# This simplify building from source on exotic platforms as patching
+# of configure.ac is not required to change results of tests.

+AC_PREREQ([2.60])
+
+dnl The general structure of the multithreading modules in gnulib is that we
+dnl have three set of modules:
+dnl
+dnl * POSIX API:
+dnl pthread, which combines
+dnl pthread-h
+dnl pthread-thread
+dnl pthread-once
+dnl pthread-mutex
+dnl pthread-rwlock
+dnl pthread-cond
+dnl pthread-tss
+dnl pthread-spin
+dnl sched_yield
+dnl
+dnl * ISO C API:
+dnl threads, which combines
+dnl threads-h
+dnl thrd
+dnl mtx
+dnl cnd
+dnl tss
+dnl
+dnl * Gnulib API, with an implementation that can be chosen at configure
+dnl time through the option --enable-threads=...
+dnl thread
+dnl lock
+dnl cond
+dnl tls
+dnl yield
+dnl
+dnl They are independent, except for the fact that
+dnl - the implementation of the ISO C API may use the POSIX (or some other
+dnl platform dependent) API,
+dnl - the implementation of the Gnulib API may use the POSIX or ISO C or
+dnl some other platform dependent API, depending on the --enable-threads
+dnl option.

+dnl This file can be used in projects which are not available under
+dnl the GNU General Public License or the GNU Lesser General Public
+dnl License but which still want to provide support for the GNU gettext
+dnl functionality.
+dnl Please note that the actual code of the GNU gettext library is covered
+dnl by the GNU Lesser General Public License, and the rest of the GNU
+dnl gettext package is covered by the GNU General Public License.
+dnl They are *not* in the public domain.
+
+dnl Authors:
+dnl Ulrich Drepper <drepper@cygnus.com>, 1995-2000.
+dnl Bruno Haible <haible@clisp.cons.org>, 2000-2006, 2008-2010.
+
+dnl Macro to add for using GNU gettext.
+
+dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
+dnl INTLSYMBOL must be one of 'external', 'use-libtool'.
+dnl INTLSYMBOL should be 'external' for packages other than GNU gettext, and
+dnl 'use-libtool' for the packages 'gettext-runtime' and 'gettext-tools'.
+dnl If INTLSYMBOL is 'use-libtool', then a libtool library
+dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
+dnl depending on --{enable,disable}-{shared,static} and on the presence of
+dnl AM-DISABLE-SHARED).
+dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
+dnl implementations (in libc or libintl) without the ngettext() function
+dnl will be ignored. If NEEDSYMBOL is specified and is
+dnl 'need-formatstring-macros', then GNU gettext implementations that don't
+dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
+dnl INTLDIR is used to find the intl libraries. If empty,
+dnl the value '$(top_builddir)/intl/' is used.
+dnl
+dnl The result of the configuration is one of three cases:
+dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
+dnl and used.
+dnl Catalog format: GNU --> install in $(datadir)
+dnl Catalog extension: .mo after installation, .gmo in source tree
+dnl 2) GNU gettext has been found in the system's C library.
+dnl Catalog format: GNU --> install in $(datadir)
+dnl Catalog extension: .mo after installation, .gmo in source tree
+dnl 3) No internationalization, always use English msgid.
+dnl Catalog format: none
+dnl Catalog extension: none
+dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
+dnl The use of .gmo is historical (it was needed to avoid overwriting the
+dnl GNU format catalogs when building on a platform with an X/Open gettext),
+dnl but we keep it in order not to force irrelevant filename changes on the
+dnl maintainers.

+
+dnl Sets the HOST_CPU variable to the canonical name of the CPU.
+dnl Sets the HOST_CPU_C_ABI variable to the canonical name of the CPU with its
+dnl C language ABI (application binary interface).
+dnl Also defines __${HOST_CPU}__ and __${HOST_CPU_C_ABI}__ as C macros in
+dnl config.h.
+dnl
+dnl This canonical name can be used to select a particular assembly language
+dnl source file that will interoperate with C code on the given host.
+dnl
+dnl For example:
+dnl * 'i386' and 'sparc' are different canonical names, because code for i386
+dnl will not run on SPARC CPUs and vice versa. They have different
+dnl instruction sets.
+dnl * 'sparc' and 'sparc64' are different canonical names, because code for
+dnl 'sparc' and code for 'sparc64' cannot be linked together: 'sparc' code
+dnl contains 32-bit instructions, whereas 'sparc64' code contains 64-bit
+dnl instructions. A process on a SPARC CPU can be in 32-bit mode or in 64-bit
+dnl mode, but not both.
+dnl * 'mips' and 'mipsn32' are different canonical names, because they use
+dnl different argument passing and return conventions for C functions, and
+dnl although the instruction set of 'mips' is a large subset of the
+dnl instruction set of 'mipsn32'.
+dnl * 'mipsn32' and 'mips64' are different canonical names, because they use
+dnl different sizes for the C types like 'int' and 'void *', and although
+dnl the instruction sets of 'mipsn32' and 'mips64' are the same.
+dnl * The same canonical name is used for different endiannesses. You can
+dnl determine the endianness through preprocessor symbols:
+dnl - 'arm': test __ARMEL__.
+dnl - 'mips', 'mipsn32', 'mips64': test _MIPSEB vs. _MIPSEL.
+dnl - 'powerpc64': test _BIG_ENDIAN vs. _LITTLE_ENDIAN.
+dnl * The same name 'i386' is used for CPUs of type i386, i486, i586
+dnl (Pentium), AMD K7, Pentium II, Pentium IV, etc., because
+dnl - Instructions that do not exist on all of these CPUs (cmpxchg,
+dnl MMX, SSE, SSE2, 3DNow! etc.) are not frequently used. If your
+dnl assembly language source files use such instructions, you will
+dnl need to make the distinction.
+dnl - Speed of execution of the common instruction set is reasonable across
+dnl the entire family of CPUs. If you have assembly language source files
+dnl that are optimized for particular CPU types (like GNU gmp has), you
+dnl will need to make the distinction.

-Abstract
-
- This document describes SPDY, a protocol designed for low-latency
- transport of content over the World Wide Web. SPDY introduces two
- layers of protocol. The lower layer is a general purpose framing
- layer which can be used atop a reliable transport (likely TCP) for
- multiplexed, prioritized, and compressed data communication of many
- concurrent streams. The upper layer of the protocol provides HTTP-
- like RFC2616 [RFC2616] semantics for compatibility with existing HTTP
- application servers.

-
-1. Overview
-
- One of the bottlenecks of HTTP implementations is that HTTP relies on
- multiple connections for concurrency. This causes several problems,
- including additional round trips for connection setup, slow-start
- delays, and connection rationing by the client, where it tries to
- avoid opening too many connections to any single server. HTTP
- pipelining helps some, but only achieves partial multiplexing. In
- addition, pipelining has proven non-deployable in existing browsers
- due to intermediary interference.
-
- SPDY adds a framing layer for multiplexing multiple, concurrent
- streams across a single TCP connection (or any reliable transport
- stream). The framing layer is optimized for HTTP-like request-
- response streams, such that applications which run over HTTP today
- can work over SPDY with little or no change on behalf of the web
- application writer.
-
- The SPDY session offers four improvements over HTTP:
-
- Multiplexed requests: There is no limit to the number of requests
- that can be issued concurrently over a single SPDY connection.
-
- Prioritized requests: Clients can request certain resources to be
- delivered first. This avoids the problem of congesting the
- network channel with non-critical resources when a high-priority
- request is pending.
-
- Compressed headers: Clients today send a significant amount of
- redundant data in the form of HTTP headers. Because a single web
- page may require 50 or 100 subrequests, this data is significant.
-
- Server pushed streams: Server Push enables content to be pushed
- from servers to clients without a request.
-
- SPDY attempts to preserve the existing semantics of HTTP. All
- features such as cookies, ETags, Vary headers, Content-Encoding
- negotiations, etc work as they do with HTTP; SPDY only replaces the
- way the data is written to the network.
-
-1.1. Document Organization
-
- The SPDY Specification is split into two parts: a framing layer
- (Section 2), which multiplexes a TCP connection into independent,
- length-prefixed frames, and an HTTP layer (Section 3), which
- specifies the mechanism for overlaying HTTP request/response pairs on
- top of the framing layer. While some of the framing layer concepts
- are isolated from the HTTP layer, building a generic framing layer
-
-
-
-Belshe & Peon Expires August 4, 2012 [Page 4]
-
-Internet-Draft SPDY Feb 2012
-
-
- has not been a goal. The framing layer is tailored to the needs of
- the HTTP protocol and server push.
-
-1.2. Definitions
-
- client: The endpoint initiating the SPDY session.
-
- connection: A transport-level connection between two endpoints.
-
- endpoint: Either the client or server of a connection.
-
- frame: A header-prefixed sequence of bytes sent over a SPDY
- session.
-
- server: The endpoint which did not initiate the SPDY session.
-
- session: A synonym for a connection.
-
- session error: An error on the SPDY session.
-
- stream: A bi-directional flow of bytes across a virtual channel
- within a SPDY session.
-
- stream error: An error on an individual SPDY stream.

-2. SPDY Framing Layer
-
-2.1. Session (Connections)
-
- The SPDY framing layer (or "session") runs atop a reliable transport
- layer such as TCP [RFC0793]. The client is the TCP connection
- initiator. SPDY connections are persistent connections.
-
- For best performance, it is expected that clients will not close open
- connections until the user navigates away from all web pages
- referencing a connection, or until the server closes the connection.
- Servers are encouraged to leave connections open for as long as
- possible, but can terminate idle connections if necessary. When
- either endpoint closes the transport-level connection, it MUST first
- send a GOAWAY (Section 2.6.6) frame so that the endpoints can
- reliably determine if requests finished before the close.
-
-2.2. Framing
-
- Once the connection is established, clients and servers exchange
- framed messages. There are two types of frames: control frames
- (Section 2.2.1) and data frames (Section 2.2.2). Frames always have
- a common header which is 8 bytes in length.
-
- The first bit is a control bit indicating whether a frame is a
- control frame or data frame. Control frames carry a version number,
- a frame type, flags, and a length. Data frames contain the stream
- ID, flags, and the length for the payload carried after the common
- header. The simple header is designed to make reading and writing of
- frames easy.
-
- All integer values, including length, version, and type, are in
- network byte order. SPDY does not enforce alignment of types in
- dynamically sized frames.
-
-2.2.1. Control frames
-
- +----------------------------------+
- |C| Version(15bits) | Type(16bits) |
- +----------------------------------+
- | Flags (8) | Length (24 bits) |
- +----------------------------------+
- | Data |
- +----------------------------------+
-
- Control bit: The 'C' bit is a single bit indicating if this is a
- control message. For control frames this value is always 1.
-
-
-
-
-Belshe & Peon Expires August 4, 2012 [Page 6]
-
-Internet-Draft SPDY Feb 2012
-
-
- Version: The version number of the SPDY protocol. This document
- describes SPDY version 3.
-
- Type: The type of control frame. See Control Frames for the complete
- list of control frames.
-
- Flags: Flags related to this frame. Flags for control frames and
- data frames are different.
-
- Length: An unsigned 24-bit value representing the number of bytes
- after the length field.
-
- Data: data associated with this control frame. The format and length
- of this data is controlled by the control frame type.
-
- Control frame processing requirements:
-
- Note that full length control frames (16MB) can be large for
- implementations running on resource-limited hardware. In such
- cases, implementations MAY limit the maximum length frame
- supported. However, all implementations MUST be able to receive
- control frames of at least 8192 octets in length.
-
-2.2.2. Data frames
-
- +----------------------------------+
- |C| Stream-ID (31bits) |
- +----------------------------------+
- | Flags (8) | Length (24 bits) |
- +----------------------------------+
- | Data |
- +----------------------------------+
-
- Control bit: For data frames this value is always 0.
-
- Stream-ID: A 31-bit value identifying the stream.
-
- Flags: Flags related to this frame. Valid flags are:
-
- 0x01 = FLAG_FIN - signifies that this frame represents the last
- frame to be transmitted on this stream. See Stream Close
- (Section 2.3.7) below.
-
- 0x02 = FLAG_COMPRESS - indicates that the data in this frame has
- been compressed.
-
- Length: An unsigned 24-bit value representing the number of bytes
- after the length field. The total size of a data frame is 8 bytes +
-
-
-
-Belshe & Peon Expires August 4, 2012 [Page 7]
-
-Internet-Draft SPDY Feb 2012
-
-
- length. It is valid to have a zero-length data frame.
-
- Data: The variable-length data payload; the length was defined in the
- length field.
-
- Data frame processing requirements:
-
- If an endpoint receives a data frame for a stream-id which is not
- open and the endpoint has not sent a GOAWAY (Section 2.6.6) frame,
- it MUST send issue a stream error (Section 2.4.2) with the error
- code INVALID_STREAM for the stream-id.
-
- If the endpoint which created the stream receives a data frame
- before receiving a SYN_REPLY on that stream, it is a protocol
- error, and the recipient MUST issue a stream error (Section 2.4.2)
- with the status code PROTOCOL_ERROR for the stream-id.
-
- Implementors note: If an endpoint receives multiple data frames
- for invalid stream-ids, it MAY close the session.
-
- All SPDY endpoints MUST accept compressed data frames.
- Compression of data frames is always done using zlib compression.
- Each stream initializes and uses its own compression context
- dedicated to use within that stream. Endpoints are encouraged to
- use application level compression rather than SPDY stream level
- compression.
-
- Each SPDY stream sending compressed frames creates its own zlib
- context for that stream, and these compression contexts MUST be
- distinct from the compression contexts used with SYN_STREAM/
- SYN_REPLY/HEADER compression. (Thus, if both endpoints of a
- stream are compressing data on the stream, there will be two zlib
- contexts, one for sending and one for receiving).
-
-2.3. Streams
-
- Streams are independent sequences of bi-directional data divided into
- frames with several properties:
-
- Streams may be created by either the client or server.
-
- Streams optionally carry a set of name/value header pairs.
-
- Streams can concurrently send data interleaved with other streams.
-
- Streams may be cancelled.

-Internet-Draft SPDY Feb 2012
-
-
-2.3.1. Stream frames
-
- SPDY defines 3 control frames to manage the lifecycle of a stream:
-
- SYN_STREAM - Open a new stream
-
- SYN_REPLY - Remote acknowledgement of a new, open stream
-
- RST_STREAM - Close a stream
-
-2.3.2. Stream creation
-
- A stream is created by sending a control frame with the type set to
- SYN_STREAM (Section 2.6.1). If the server is initiating the stream,
- the Stream-ID must be even. If the client is initiating the stream,
- the Stream-ID must be odd. 0 is not a valid Stream-ID. Stream-IDs
- from each side of the connection must increase monotonically as new
- streams are created. E.g. Stream 2 may be created after stream 3,
- but stream 7 must not be created after stream 9. Stream IDs do not
- wrap: when a client or server cannot create a new stream id without
- exceeding a 31 bit value, it MUST NOT create a new stream.
-
- The stream-id MUST increase with each new stream. If an endpoint
- receives a SYN_STREAM with a stream id which is less than any
- previously received SYN_STREAM, it MUST issue a session error
- (Section 2.4.1) with the status PROTOCOL_ERROR.
-
- It is a protocol error to send two SYN_STREAMs with the same
- stream-id. If a recipient receives a second SYN_STREAM for the same
- stream, it MUST issue a stream error (Section 2.4.2) with the status
- code PROTOCOL_ERROR.
-
- Upon receipt of a SYN_STREAM, the recipient can reject the stream by
- sending a stream error (Section 2.4.2) with the error code
- REFUSED_STREAM. Note, however, that the creating endpoint may have
- already sent additional frames for that stream which cannot be
- immediately stopped.
-
- Once the stream is created, the creator may immediately send HEADERS
- or DATA frames for that stream, without needing to wait for the
- recipient to acknowledge.
-
-2.3.2.1. Unidirectional streams
-
- When an endpoint creates a stream with the FLAG_UNIDIRECTIONAL flag
- set, it creates a unidirectional stream which the creating endpoint
- can use to send frames, but the receiving endpoint cannot. The
- receiving endpoint is implicitly already in the half-closed
-
-
-
-Belshe & Peon Expires August 4, 2012 [Page 9]
-
-Internet-Draft SPDY Feb 2012
-
-
- (Section 2.3.6) state.
-
-2.3.2.2. Bidirectional streams
-
- SYN_STREAM frames which do not use the FLAG_UNIDIRECTIONAL flag are
- bidirectional streams. Both endpoints can send data on a bi-
- directional stream.
-
-2.3.3. Stream priority
-
- The creator of a stream assigns a priority for that stream. Priority
- is represented as an integer from 0 to 7. 0 represents the highest
- priority and 7 represents the lowest priority.
-
- The sender and recipient SHOULD use best-effort to process streams in
- the order of highest priority to lowest priority.
-
-2.3.4. Stream headers
-
- Streams carry optional sets of name/value pair headers which carry
- metadata about the stream. After the stream has been created, and as
- long as the sender is not closed (Section 2.3.7) or half-closed
- (Section 2.3.6), each side may send HEADERS frame(s) containing the
- header data. Header data can be sent in multiple HEADERS frames, and
- HEADERS frames may be interleaved with data frames.
-
-2.3.5. Stream data exchange
-
- Once a stream is created, it can be used to send arbitrary amounts of
- data. Generally this means that a series of data frames will be sent
- on the stream until a frame containing the FLAG_FIN flag is set. The
- FLAG_FIN can be set on a SYN_STREAM (Section 2.6.1), SYN_REPLY
- (Section 2.6.2), HEADERS (Section 2.6.7) or a DATA (Section 2.2.2)
- frame. Once the FLAG_FIN has been sent, the stream is considered to
- be half-closed.
-
-2.3.6. Stream half-close
-
- When one side of the stream sends a frame with the FLAG_FIN flag set,
- the stream is half-closed from that endpoint. The sender of the
- FLAG_FIN MUST NOT send further frames on that stream. When both
- sides have half-closed, the stream is closed.
-
- If an endpoint receives a data frame after the stream is half-closed
- from the sender (e.g. the endpoint has already received a prior frame
- for the stream with the FIN flag set), it MUST send a RST_STREAM to
- the sender with the status STREAM_ALREADY_CLOSED.

-
-
-2.3.7. Stream close
-
- There are 3 ways that streams can be terminated:
-
- Normal termination: Normal stream termination occurs when both
- sender and recipient have half-closed the stream by sending a
- FLAG_FIN.
-
- Abrupt termination: Either the client or server can send a
- RST_STREAM control frame at any time. A RST_STREAM contains an
- error code to indicate the reason for failure. When a RST_STREAM
- is sent from the stream originator, it indicates a failure to
- complete the stream and that no further data will be sent on the
- stream. When a RST_STREAM is sent from the stream recipient, the
- sender, upon receipt, should stop sending any data on the stream.
- The stream recipient should be aware that there is a race between
- data already in transit from the sender and the time the
- RST_STREAM is received. See Stream Error Handling (Section 2.4.2)
-
- TCP connection teardown: If the TCP connection is torn down while
- un-closed streams exist, then the endpoint must assume that the
- stream was abnormally interrupted and may be incomplete.
-
- If an endpoint receives a data frame after the stream is closed, it
- must send a RST_STREAM to the sender with the status PROTOCOL_ERROR.
-
-2.4. Error Handling
-
- The SPDY framing layer has only two types of errors, and they are
- always handled consistently. Any reference in this specification to
- "issue a session error" refers to Section 2.4.1. Any reference to
- "issue a stream error" refers to Section 2.4.2.
-
-2.4.1. Session Error Handling
-
- A session error is any error which prevents further processing of the
- framing layer or which corrupts the session compression state. When
- a session error occurs, the endpoint encountering the error MUST
- first send a GOAWAY (Section 2.6.6) frame with the stream id of most
- recently received stream from the remote endpoint, and the error code
- for why the session is terminating. After sending the GOAWAY frame,
- the endpoint MUST close the TCP connection.
-
- Note that the session compression state is dependent upon both
- endpoints always processing all compressed data. If an endpoint
- partially processes a frame containing compressed data without
- updating compression state properly, future control frames which use
- compression will be always be errored. Implementations SHOULD always
-
-
-
-Belshe & Peon Expires August 4, 2012 [Page 11]
-
-Internet-Draft SPDY Feb 2012
-
-
- try to process compressed data so that errors which could be handled
- as stream errors do not become session errors.
-
- Note that because this GOAWAY is sent during a session error case, it
- is possible that the GOAWAY will not be reliably received by the
- receiving endpoint. It is a best-effort attempt to communicate with
- the remote about why the session is going down.
-
-2.4.2. Stream Error Handling
-
- A stream error is an error related to a specific stream-id which does
- not affect processing of other streams at the framing layer. Upon a
- stream error, the endpoint MUST send a RST_STREAM (Section 2.6.3)
- frame which contains the stream id of the stream where the error
- occurred and the error status which caused the error. After sending
- the RST_STREAM, the stream is closed to the sending endpoint. After
- sending the RST_STREAM, if the sender receives any frames other than
- a RST_STREAM for that stream id, it will result in sending additional
- RST_STREAM frames. An endpoint MUST NOT send a RST_STREAM in
- response to an RST_STREAM, as doing so would lead to RST_STREAM
- loops. Sending a RST_STREAM does not cause the SPDY session to be
- closed.
-
- If an endpoint has multiple RST_STREAM frames to send in succession
- for the same stream-id and the same error code, it MAY coalesce them
- into a single RST_STREAM frame. (This can happen if a stream is
- closed, but the remote sends multiple data frames. There is no
- reason to send a RST_STREAM for each frame in succession).
-
-2.5. Data flow
-
- Because TCP provides a single stream of data on which SPDY
- multiplexes multiple logical streams, clients and servers must
- intelligently interleave data messages for concurrent sessions.
-
-2.6. Control frame types
-
-2.6.1. SYN_STREAM
-
- The SYN_STREAM control frame allows the sender to asynchronously
- create a stream between the endpoints. See Stream Creation
- (Section 2.3.2)

-
- 7 - FLOW_CONTROL_ERROR. The endpoint detected that its peer

-
- 8 - STREAM_IN_USE. The endpoint received a SYN_REPLY for a stream

-
- 11 - FRAME_TOO_LARGE. The endpoint received a frame which this

- a SYN_STREAM, HEADERS, or SYN_REPLY frame without fully processing
- the compressed portion of those frames, then the compression state
- will be out-of-sync with the other endpoint. In this case,
- senders of FRAME_TOO_LARGE MUST close the session.
-
- Note: 0 is not a valid status code for a RST_STREAM.
-
- After receiving a RST_STREAM on a stream, the recipient must not send
- additional frames for that stream, and the stream moves into the
- closed state.
-
-2.6.4. SETTINGS
-
- A SETTINGS frame contains a set of id/value pairs for communicating
- configuration data about how the two endpoints may communicate.
- SETTINGS frames can be sent at any time by either endpoint, are
- optionally sent, and are fully asynchronous. When the server is the
- sender, the sender can request that configuration data be persisted
- by the client across SPDY sessions and returned to the server in
- future communications.

-

-
-
- Persistence of SETTINGS ID/Value pairs is done on a per origin/IP
- pair (the "origin" is the set of scheme, host, and port from the URI.
- See [RFC6454]). That is, when a client connects to a server, and the
- server persists settings within the client, the client SHOULD return
- the persisted settings on future connections to the same origin AND
- IP address and TCP port. Clients MUST NOT request servers to use the
- persistence features of the SETTINGS frames, and servers MUST ignore
- persistence related flags sent by a client.

- Flags: FLAG_SETTINGS_CLEAR_SETTINGS (0x1): When set, the client
- should clear any previously persisted SETTINGS ID/Value pairs. If
- this frame contains ID/Value pairs with the
- FLAG_SETTINGS_PERSIST_VALUE set, then the client will first clear its
- existing, persisted settings, and then persist the values with the
- flag set which are contained within this frame. Because persistence
- is only implemented on the client, this flag can only be used when
- the sender is the server.
-
- Length: An unsigned 24-bit value representing the number of bytes
- after the length field. The total size of a SETTINGS frame is 8
- bytes + length.

- sender to this recipient. Because persistence is only
- implemented on the client, this flag is only sent by the
- server.
-
- FLAG_SETTINGS_PERSISTED (0x2): When set, the sender is
- notifying the recipient that this ID/Value pair was previously
- sent to the sender by the recipient with the
- FLAG_SETTINGS_PERSIST_VALUE, and the sender is returning it.
- Because persistence is only implemented on the client, this
- flag is only sent by the client.
-
- Defined IDs:
-
- 1 - SETTINGS_UPLOAD_BANDWIDTH allows the sender to send its
- expected upload bandwidth on this channel. This number is an
- estimate. The value should be the integral number of kilobytes
- per second that the sender predicts as an expected maximum
- upload channel capacity.
-
- 2 - SETTINGS_DOWNLOAD_BANDWIDTH allows the sender to send its
- expected download bandwidth on this channel. This number is an
- estimate. The value should be the integral number of kilobytes
- per second that the sender predicts as an expected maximum
- download channel capacity.
-
- 3 - SETTINGS_ROUND_TRIP_TIME allows the sender to send its
- expected round-trip-time on this channel. The round trip time
- is defined as the minimum amount of time to send a control
- frame from this client to the remote and receive a response.
- The value is represented in milliseconds.
-
- 4 - SETTINGS_MAX_CONCURRENT_STREAMS allows the sender to inform
- the remote endpoint the maximum number of concurrent streams
- which it will allow. By default there is no limit. For
- implementors it is recommended that this value be no smaller
- than 100.
-
- 5 - SETTINGS_CURRENT_CWND allows the sender to inform the
- remote endpoint of the current TCP CWND value.
-
- 6 - SETTINGS_DOWNLOAD_RETRANS_RATE allows the sender to inform
- the remote endpoint the retransmission rate (bytes
- retransmitted / total bytes transmitted).
-
- 7 - SETTINGS_INITIAL_WINDOW_SIZE allows the sender to inform
- the remote endpoint the initial window size (in bytes) for new
- streams.

-
-
- 8 - SETTINGS_CLIENT_CERTIFICATE_VECTOR_SIZE allows the server
- to inform the client if the new size of the client certificate
- vector.
-
- Value: A 32-bit value.
-
- The message is intentionally extensible for future information which
- may improve client-server communications. The sender does not need
- to send every type of ID/value. It must only send those for which it
- has accurate values to convey. When multiple ID/value pairs are
- sent, they should be sent in order of lowest id to highest id. A
- single SETTINGS frame MUST not contain multiple values for the same
- ID. If the recipient of a SETTINGS frame discovers multiple values
- for the same ID, it MUST ignore all values except the first one.
-
- A server may send multiple SETTINGS frames containing different ID/
- Value pairs. When the same ID/Value is sent twice, the most recent
- value overrides any previously sent values. If the server sends IDs
- 1, 2, and 3 with the FLAG_SETTINGS_PERSIST_VALUE in a first SETTINGS
- frame, and then sends IDs 4 and 5 with the
- FLAG_SETTINGS_PERSIST_VALUE, when the client returns the persisted
- state on its next SETTINGS frame, it SHOULD send all 5 settings (1,
- 2, 3, 4, and 5 in this example) to the server.
-
-2.6.5. PING
-
- The PING control frame is a mechanism for measuring a minimal round-
- trip time from the sender. It can be sent from the client or the
- server. Recipients of a PING frame should send an identical frame to
- the sender as soon as possible (if there is other pending data
- waiting to be sent, PING should take highest priority). Each ping
- sent by a sender should use a unique ID.

-
-Internet-Draft SPDY Feb 2012
-
-
- ID: A unique ID for this ping, represented as an unsigned 32 bit
- value. When the client initiates a ping, it must use an odd numbered
- ID. When the server initiates a ping, it must use an even numbered
- ping. Use of odd/even IDs is required in order to avoid accidental
- looping on PINGs (where each side initiates an identical PING at the
- same time).
-
- Note: If a sender uses all possible PING ids (e.g. has sent all 2^31
- possible IDs), it can wrap and start re-using IDs.
-
- If a server receives an even numbered PING which it did not initiate,
- it must ignore the PING. If a client receives an odd numbered PING
- which it did not initiate, it must ignore the PING.
-
-2.6.6. GOAWAY
-
- The GOAWAY control frame is a mechanism to tell the remote side of
- the connection to stop creating streams on this session. It can be
- sent from the client or the server. Once sent, the sender will not
- respond to any new SYN_STREAMs on this session. Recipients of a
- GOAWAY frame must not send additional streams on this session,
- although a new session can be established for new streams. The
- purpose of this message is to allow an endpoint to gracefully stop
- accepting new streams (perhaps for a reboot or maintenance), while
- still finishing processing of previously established streams.
-
- There is an inherent race condition between an endpoint sending
- SYN_STREAMs and the remote sending a GOAWAY message. To deal with
- this case, the GOAWAY contains a last-stream-id indicating the
- stream-id of the last stream which was created on the sending
- endpoint in this session. If the receiver of the GOAWAY sent new
- SYN_STREAMs for sessions after this last-stream-id, they were not
- processed by the server and the receiver may treat the stream as
- though it had never been created at all (hence the receiver may want
- to re-create the stream later on a new session).
-
- Endpoints should always send a GOAWAY message before closing a
- connection so that the remote can know whether a stream has been
- partially processed or not. (For example, if an HTTP client sends a
- POST at the same time that a server closes a connection, the client
- cannot know if the server started to process that POST request if the
- server does not send a GOAWAY frame to indicate where it stopped
- working).
-
- After sending a GOAWAY message, the sender must ignore all SYN_STREAM
- frames for new streams.

-
-2.6.8. WINDOW_UPDATE
-
- The WINDOW_UPDATE control frame is used to implement per stream flow
- control in SPDY. Flow control in SPDY is per hop, that is, only
- between the two endpoints of a SPDY connection. If there are one or
- more intermediaries between the client and the origin server, flow
- control signals are not explicitly forwarded by the intermediaries.
- (However, throttling of data transfer by any recipient may have the
- effect of indirectly propagating flow control information upstream
- back to the original sender.) Flow control only applies to the data
- portion of data frames. Recipients must buffer all control frames.
- If a recipient fails to buffer an entire control frame, it MUST issue
- a stream error (Section 2.4.2) with the status code
- FLOW_CONTROL_ERROR for the stream.
-
-
-
-Belshe & Peon Expires August 4, 2012 [Page 22]
-
-Internet-Draft SPDY Feb 2012
-
-
- Flow control in SPDY is implemented by a data transfer window kept by
- the sender of each stream. The data transfer window is a simple
- uint32 that indicates how many bytes of data the sender can transmit.
- After a stream is created, but before any data frames have been
- transmitted, the sender begins with the initial window size. This
- window size is a measure of the buffering capability of the
- recipient. The sender must not send a data frame with data length
- greater than the transfer window size. After sending each data
- frame, the sender decrements its transfer window size by the amount
- of data transmitted. When the window size becomes less than or equal
- to 0, the sender must pause transmitting data frames. At the other
- end of the stream, the recipient sends a WINDOW_UPDATE control back
- to notify the sender that it has consumed some data and freed up
- buffer space to receive more data.

- Stream-ID: The stream ID that this WINDOW_UPDATE control frame is
- for.
-
- Delta-Window-Size: The additional number of bytes that the sender can
- transmit in addition to existing remaining window size. The legal
- range for this field is 1 to 2^31 - 1 (0x7fffffff) bytes.
-
- The window size as kept by the sender must never exceed 2^31
- (although it can become negative in one special case). If a sender
- receives a WINDOW_UPDATE that causes the its window size to exceed
- this limit, it must send RST_STREAM with status code
- FLOW_CONTROL_ERROR to terminate the stream.
-
- When a SPDY connection is first established, the default initial
-

-
-
- window size for all streams is 64KB. An endpoint can use the
- SETTINGS control frame to adjust the initial window size for the
- connection. That is, its peer can start out using the 64KB default
- initial window size when sending data frames before receiving the
- SETTINGS. Because SETTINGS is asynchronous, there may be a race
- condition if the recipient wants to decrease the initial window size,
- but its peer immediately sends 64KB on the creation of a new
- connection, before waiting for the SETTINGS to arrive. This is one
- case where the window size kept by the sender will become negative.
- Once the sender detects this condition, it must stop sending data
- frames and wait for the recipient to catch up. The recipient has two
- choices:
-
- immediately send RST_STREAM with FLOW_CONTROL_ERROR status code.
-
- allow the head of line blocking (as there is only one stream for
- the session and the amount of data in flight is bounded by the
- default initial window size), and send WINDOW_UPDATE as it
- consumes data.
-
- In the case of option 2, both sides must compute the window size
- based on the initial window size in the SETTINGS. For example, if
- the recipient sets the initial window size to be 16KB, and the sender
- sends 64KB immediately on connection establishment, the sender will
- discover its window size is -48KB on receipt of the SETTINGS. As the
- recipient consumes the first 16KB, it must send a WINDOW_UPDATE of
- 16KB back to the sender. This interaction continues until the
- sender's window size becomes positive again, and it can resume
- transmitting data frames.
-
- After the recipient reads in a data frame with FLAG_FIN that marks
- the end of the data stream, it should not send WINDOW_UPDATE frames
- as it consumes the last data frame. A sender should ignore all the
- WINDOW_UPDATE frames associated with the stream after it send the
- last frame for the stream.
-
- The data frames from the sender and the WINDOW_UPDATE frames from the
- recipient are completely asynchronous with respect to each other.
- This property allows a recipient to aggressively update the window
- size kept by the sender to prevent the stream from stalling.
-
-2.6.9. CREDENTIAL
-
- The CREDENTIAL control frame is used by the client to send additional
- client certificates to the server. A SPDY client may decide to send
- requests for resources from different origins on the same SPDY
- session if it decides that that server handles both origins. For
- example if the IP address associated with both hostnames matches and
-
-
-

-
-Internet-Draft SPDY Feb 2012
-
-
- the SSL server certificate presented in the initial handshake is
- valid for both hostnames. However, because the SSL connection can
- contain at most one client certificate, the client needs a mechanism
- to send additional client certificates to the server.
-
- The server is required to maintain a vector of client certificates
- associated with a SPDY session. When the client needs to send a
- client certificate to the server, it will send a CREDENTIAL frame
- that specifies the index of the slot in which to store the
- certificate as well as proof that the client posesses the
- corresponding private key. The initial size of this vector must be
- 8. If the client provides a client certificate during the first TLS
- handshake, the contents of this certificate must be copied into the
- first slot (index 1) in the CREDENTIAL vector, though it may be
- overwritten by subsequent CREDENTIAL frames. The server must
- exclusively use the CREDNETIAL vector when evaluating the client
- certificates associated with an origin. The server may change the
- size of this vector by sending a SETTINGS frame with the setting
- SETTINGS_CLIENT_CERTIFICATE_VECTOR_SIZE value specified. In the
- event that the new size is smaller than the current size, truncation
- occurs preserving lower-index slots as possible.
-
- TLS renegotiation with client authentication is incompatible with
- SPDY given the multiplexed nature of SPDY. Specifically, imagine
- that the client has 2 requests outstanding to the server for two
- different pages (in different tabs). When the renegotiation + client
- certificate request comes in, the browser is unable to determine
- which resource triggered the client certificate request, in order to
- prompt the user accordingly.

- stored at this index, it will be overwritten. The index is one
- based, not zero based; zero is an invalid slot index.
-
- Proof: Cryptographic proof that the client has possession of the
- private key associated with the certificate. The format is a TLS
- digitally-signed element
- (http://tools.ietf.org/html/rfc5246#section-4.7). The signature
- algorithm must be the same as that used in the CertificateVerify
- message. However, since the MD5+SHA1 signature type used in TLS 1.0
- connections can not be correctly encoded in a digitally-signed
- element, SHA1 must be used when MD5+SHA1 was used in the SSL
- connection. The signature is calculated over a 32 byte TLS extractor
- value (http://tools.ietf.org/html/rfc5705) with a label of "EXPORTER
- SPDY certificate proof" using the empty string as context. ForRSA
- certificates the signature would be a PKCS#1 v1.5 signature. For
- ECDSA, it would be an ECDSA-Sig-Value
- (http://tools.ietf.org/html/rfc5480#appendix-A). For a 1024-bit RSA
- key, the CREDENTIAL message would be ~500 bytes.
-
- Certificate: The certificate chain, starting with the leaf
- certificate. Each certificate must be encoded as a 32 bit length,
- followed by a DER encoded certificate. The certificate must be of
- the same type (RSA, ECDSA, etc) as the client certificate associated
- with the SSL connection.
-
- If the server receives a request for a resource with unacceptable
- credential (either missing or invalid), it must reply with a
- RST_STREAM frame with the status code INVALID_CREDENTIALS. Upon
- receipt of a RST_STREAM frame with INVALID_CREDENTIALS, the client
- should initiate a new stream directly to the requested origin and
- resend the request. Note, SPDY does not allow the server to request
- different client authentication for different resources in the same
- origin.
-
- If the server receives an invalid CREDENTIAL frame, it MUST respond
- with a GOAWAY frame and shutdown the session.

- Number of Name/Value pairs: The number of repeating name/value pairs

-
- List of Name/Value pairs:
-
- Length of Name: a 32-bit value containing the number of octets in
- the name field. Note that in practice, this length must not
- exceed 2^24, as that is the maximum size of a SPDY frame.
-
- Name: 0 or more octets, 8-bit sequences of data, excluding 0.

- Length of Value: a 32-bit value containing the number of octets in
- the value field. Note that in practice, this length must not
- exceed 2^24, as that is the maximum size of a SPDY frame.
-
- Value: 0 or more octets, 8-bit sequences of data, excluding 0.
-
- Each header name must have at least one value. Header names are
- encoded using the US-ASCII character set [ASCII] and must be all
- lower case. The length of each name must be greater than zero. A
- recipient of a zero-length name MUST issue a stream error
- (Section 2.4.2) with the status code PROTOCOL_ERROR for the
- stream-id.
-
- Duplicate header names are not allowed. To send two identically
- named headers, send a header with two values, where the values are
- separated by a single NUL (0) byte. A header value can either be
- empty (e.g. the length is zero) or it can contain multiple, NUL-
- separated values, each with length greater than zero. The value
- never starts nor ends with a NUL character. Recipients of illegal
- value fields MUST issue a stream error (Section 2.4.2) with the
- status code PROTOCOL_ERROR for the stream-id.

-2.6.10.1. Compression
-
- The Name/Value Header Block is a section of the SYN_STREAM,
- SYN_REPLY, and HEADERS frames used to carry header meta-data. This
- block is always compressed using zlib compression. Within this
- specification, any reference to 'zlib' is referring to the ZLIB
- Compressed Data Format Specification Version 3.3 as part of RFC1950.
- [RFC1950]
-
- For each HEADERS compression instance, the initial state is
- initialized using the following dictionary [UDELCOMPRESSION]:

- The entire contents of the name/value header block is compressed
- using zlib. There is a single zlib stream for all name value pairs
- in one direction on a connection. SPDY uses a SYNC_FLUSH between
- each compressed frame.
-
- Implementation notes: the compression engine can be tuned to favor
- speed or size. Optimizing for size increases memory use and CPU
- consumption. Because header blocks are generally small, implementors
- may want to reduce the window-size of the compression engine from the
- default 15bits (a 32KB window) to more like 11bits (a 2KB window).
- The exact setting is chosen by the compressor, the decompressor will
- work with any setting.

-3. HTTP Layering over SPDY
-
- SPDY is intended to be as compatible as possible with current web-
- based applications. This means that, from the perspective of the
- server business logic or application API, the features of HTTP are
- unchanged. To achieve this, all of the application request and
- response header semantics are preserved, although the syntax of
- conveying those semantics has changed. Thus, the rules from the
- HTTP/1.1 specification in RFC2616 [RFC2616] apply with the changes in
- the sections below.
-
-3.1. Connection Management
-
- Clients SHOULD NOT open more than one SPDY session to a given origin
- [RFC6454] concurrently.
-
- Note that it is possible for one SPDY session to be finishing (e.g. a
- GOAWAY message has been sent, but not all streams have finished),
- while another SPDY session is starting.
-
-3.1.1. Use of GOAWAY
-
- SPDY provides a GOAWAY message which can be used when closing a
- connection from either the client or server. Without a server GOAWAY
- message, HTTP has a race condition where the client sends a request
- (a new SYN_STREAM) just as the server is closing the connection, and
- the client cannot know if the server received the stream or not. By
- using the last-stream-id in the GOAWAY, servers can indicate to the
- client if a request was processed or not.
-
- Note that some servers will choose to send the GOAWAY and immediately
- terminate the connection without waiting for active streams to
- finish. The client will be able to determine this because SPDY
- streams are determinstically closed. This abrupt termination will
- force the client to heuristically decide whether to retry the pending
- requests. Clients always need to be capable of dealing with this
- case because they must deal with accidental connection termination
- cases, which are the same as the server never having sent a GOAWAY.
-
- More sophisticated servers will use GOAWAY to implement a graceful
- teardown. They will send the GOAWAY and provide some time for the
- active streams to finish before terminating the connection.
-
- If a SPDY client closes the connection, it should also send a GOAWAY
- message. This allows the server to know if any server-push streams
- were received by the client.
-
- If the endpoint closing the connection has not received any
-
-

-
-Internet-Draft SPDY Feb 2012
-
-
- SYN_STREAMs from the remote, the GOAWAY will contain a last-stream-id
- of 0.
-
-3.2. HTTP Request/Response
-
-3.2.1. Request
-
- The client initiates a request by sending a SYN_STREAM frame. For
- requests which do not contain a body, the SYN_STREAM frame MUST set
- the FLAG_FIN, indicating that the client intends to send no further
- data on this stream. For requests which do contain a body, the
- SYN_STREAM will not contain the FLAG_FIN, and the body will follow
- the SYN_STREAM in a series of DATA frames. The last DATA frame will
- set the FLAG_FIN to indicate the end of the body.
-
- The SYN_STREAM Name/Value section will contain all of the HTTP
- headers which are associated with an HTTP request. The header block
- in SPDY is mostly unchanged from today's HTTP header block, with the
- following differences:
-
- The first line of the request is unfolded into name/value pairs
- like other HTTP headers and MUST be present:
-
- ":method" - the HTTP method for this request (e.g. "GET",
- "POST", "HEAD", etc)
-
- ":path" - the url-path for this url with "/" prefixed. (See
- RFC1738 [RFC1738]). For example, for
- "http://www.google.com/search?q=dogs" the path would be
- "/search?q=dogs".
-
- ":version" - the HTTP version of this request (e.g.
- "HTTP/1.1")
-
- In addition, the following two name/value pairs must also be
- present in every request:
-
- ":host" - the hostport (See RFC1738 [RFC1738]) portion of the
- URL for this request (e.g. "www.google.com:1234"). This header
- is the same as the HTTP 'Host' header.
-
- ":scheme" - the scheme portion of the URL for this request
- (e.g. "https"))
-
- Header names are all lowercase.
-
- The Connection, Host, Keep-Alive, Proxy-Connection, and Transfer-
- Encoding headers are not valid and MUST not be sent.
-
-
-

-
-
- User-agents MUST support gzip compression. Regardless of the
- Accept-Encoding sent by the user-agent, the server may always send
- content encoded with gzip or deflate encoding.
-
- If a server receives a request where the sum of the data frame
- payload lengths does not equal the size of the Content-Length
- header, the server MUST return a 400 (Bad Request) error.
-
- POST-specific changes:
-
- Although POSTs are inherently chunked, POST requests SHOULD
- also be accompanied by a Content-Length header. There are two
- reasons for this: First, it assists with upload progress meters
- for an improved user experience. But second, we know from
- early versions of SPDY that failure to send a content length
- header is incompatible with many existing HTTP server
- implementations. Existing user-agents do not omit the Content-
- Length header, and server implementations have come to depend
- upon this.
-
- The user-agent is free to prioritize requests as it sees fit. If the
- user-agent cannot make progress without receiving a resource, it
- should attempt to raise the priority of that resource. Resources
- such as images, SHOULD generally use the lowest priority.
-
- If a client sends a SYN_STREAM without all of the method, host, path,
- scheme, and version headers, the server MUST reply with a HTTP 400
- Bad Request reply.
-
-3.2.2. Response
-
- The server responds to a client request with a SYN_REPLY frame.
- Symmetric to the client's upload stream, server will send data after
- the SYN_REPLY frame via a series of DATA frames, and the last data
- frame will contain the FLAG_FIN to indicate successful end-of-stream.
- If a response (like a 202 or 204 response) contains no body, the
- SYN_REPLY frame may contain the FLAG_FIN flag to indicate no further
- data will be sent on the stream.
-
- The response status line is unfolded into name/value pairs like
- other HTTP headers and must be present:
-
- ":status" - The HTTP response status code (e.g. "200" or "200
- OK")
-
- ":version" - The HTTP response version (e.g. "HTTP/1.1")
-

-
-
- All header names must be lowercase.
-
- The Connection, Keep-Alive, Proxy-Connection, and Transfer-
- Encoding headers are not valid and MUST not be sent.
-
- Responses MAY be accompanied by a Content-Length header for
- advisory purposes. (e.g. for UI progress meters)
-
- If a client receives a response where the sum of the data frame
- payload lengths does not equal the size of the Content-Length
- header, the client MUST ignore the content length header.
-
- If a client receives a SYN_REPLY without a status or without a
- version header, the client must reply with a RST_STREAM frame
- indicating a PROTOCOL ERROR.
-
-3.2.3. Authentication
-
- When a client sends a request to an origin server that requires
- authentication, the server can reply with a "401 Unauthorized"
- response, and include a WWW-Authenticate challenge header that
- defines the authentication scheme to be used. The client then
- retries the request with an Authorization header appropriate to the
- specified authentication scheme.
-
- There are four options for proxy authentication, Basic, Digest, NTLM
- and Negotiate (SPNEGO). The first two options were defined in
- RFC2617 [RFC2617], and are stateless. The second two options were
- developed by Microsoft and specified in RFC4559 [RFC4559], and are
- stateful; otherwise known as multi-round authentication, or
- connection authentication.
-
-3.2.3.1. Stateless Authentication
-
- Stateless Authentication over SPDY is identical to how it is
- performed over HTTP. If multiple SPDY streams are concurrently sent
- to a single server, each will authenticate independently, similar to
- how two HTTP connections would independently authenticate to a proxy
- server.
-
-3.2.3.2. Stateful Authentication
-
- Unfortunately, the stateful authentication mechanisms were
- implemented and defined in a such a way that directly violates
- RFC2617 - they do not include a "realm" as part of the request. This
- is problematic in SPDY because it makes it impossible for a client to
- disambiguate two concurrent server authentication challenges.
-
-
-
-
-Belshe & Peon Expires August 4, 2012 [Page 36]
-
-Internet-Draft SPDY Feb 2012
-
-
- To deal with this case, SPDY servers using Stateful Authentication
- MUST implement one of two changes:
-
- Servers can add a "realm=<desired realm>" header so that the two
- authentication requests can be disambiguated and run concurrently.
- Unfortunately, given how these mechanisms work, this is probably
- not practical.
-
- Upon sending the first stateful challenge response, the server
- MUST buffer and defer all further frames which are not part of
- completing the challenge until the challenge has completed.
- Completing the authentication challenge may take multiple round
- trips. Once the client receives a "401 Authenticate" response for
- a stateful authentication type, it MUST stop sending new requests
- to the server until the authentication has completed by receiving
- a non-401 response on at least one stream.
-
-3.3. Server Push Transactions
-
- SPDY enables a server to send multiple replies to a client for a
- single request. The rationale for this feature is that sometimes a
- server knows that it will need to send multiple resources in response
- to a single request. Without server push features, the client must
- first download the primary resource, then discover the secondary
- resource(s), and request them. Pushing of resources avoids the
- round-trip delay, but also creates a potential race where a server
- can be pushing content which a user-agent is in the process of
- requesting. The following mechanics attempt to prevent the race
- condition while enabling the performance benefit.
-
- Browsers receiving a pushed response MUST validate that the server is
- authorized to push the URL using the browser same-origin [RFC6454]
- policy. For example, a SPDY connection to www.foo.com is generally
- not permitted to push a response for www.evil.com.
-
- If the browser accepts a pushed response (e.g. it does not send a
- RST_STREAM), the browser MUST attempt to cache the pushed response in
- same way that it would cache any other response. This means
- validating the response headers and inserting into the disk cache.
-
- Because pushed responses have no request, they have no request
- headers associated with them. At the framing layer, SPDY pushed
- streams contain an "associated-stream-id" which indicates the
- requested stream for which the pushed stream is related. The pushed
- stream inherits all of the headers from the associated-stream-id with
- the exception of ":host", ":scheme", and ":path", which are provided
- as part of the pushed response stream headers. The browser MUST
- store these inherited and implied request headers with the cached
-
-
-

-
-Internet-Draft SPDY Feb 2012
-
-
- resource.
-
- Implementation note: With server push, it is theoretically possible
- for servers to push unreasonable amounts of content or resources to
- the user-agent. Browsers MUST implement throttles to protect against
- unreasonable push attacks.
-
-3.3.1. Server implementation
-
- When the server intends to push a resource to the user-agent, it
- opens a new stream by sending a unidirectional SYN_STREAM. The
- SYN_STREAM MUST include an Associated-To-Stream-ID, and MUST set the
- FLAG_UNIDIRECTIONAL flag. The SYN_STREAM MUST include headers for
- ":scheme", ":host", ":path", which represent the URL for the resource
- being pushed. Subsequent headers may follow in HEADERS frames. The
- purpose of the association is so that the user-agent can
- differentiate which request induced the pushed stream; without it, if
- the user-agent had two tabs open to the same page, each pushing
- unique content under a fixed URL, the user-agent would not be able to
- differentiate the requests.
-
- The Associated-To-Stream-ID must be the ID of an existing, open
- stream. The reason for this restriction is to have a clear endpoint
- for pushed content. If the user-agent requested a resource on stream
- 11, the server replies on stream 11. It can push any number of
- additional streams to the client before sending a FLAG_FIN on stream
- 11. However, once the originating stream is closed no further push
- streams may be associated with it. The pushed streams do not need to
- be closed (FIN set) before the originating stream is closed, they
- only need to be created before the originating stream closes.
-
- It is illegal for a server to push a resource with the Associated-To-
- Stream-ID of 0.
-
- To minimize race conditions with the client, the SYN_STREAM for the
- pushed resources MUST be sent prior to sending any content which
- could allow the client to discover the pushed resource and request
- it.
-
- The server MUST only push resources which would have been returned
- from a GET request.
-
- Note: If the server does not have all of the Name/Value Response
- headers available at the time it issues the HEADERS frame for the
- pushed resource, it may later use an additional HEADERS frame to
- augment the name/value pairs to be associated with the pushed stream.
- The subsequent HEADERS frame(s) must not contain a header for
- ':host', ':scheme', or ':path' (e.g. the server can't change the
-
-
-
-Belshe & Peon Expires August 4, 2012 [Page 38]
-
-Internet-Draft SPDY Feb 2012
-
-
- identity of the resource to be pushed). The HEADERS frame must not
- contain duplicate headers with a previously sent HEADERS frame. The
- server must send a HEADERS frame including the scheme/host/port
- headers before sending any data frames on the stream.
-
-3.3.2. Client implementation
-
- When fetching a resource the client has 3 possibilities:
-
- the resource is not being pushed
-
- the resource is being pushed, but the data has not yet arrived
-
- the resource is being pushed, and the data has started to arrive
-
- When a SYN_STREAM and HEADERS frame which contains an Associated-To-
- Stream-ID is received, the client must not issue GET requests for the
- resource in the pushed stream, and instead wait for the pushed stream
- to arrive.
-
- If a client receives a server push stream with stream-id 0, it MUST
- issue a session error (Section 2.4.1) with the status code
- PROTOCOL_ERROR.
-
- When a client receives a SYN_STREAM from the server without a the
- ':host', ':scheme', and ':path' headers in the Name/Value section, it
- MUST reply with a RST_STREAM with error code HTTP_PROTOCOL_ERROR.
-
- To cancel individual server push streams, the client can issue a
- stream error (Section 2.4.2) with error code CANCEL. Upon receipt,
- the server MUST stop sending on this stream immediately (this is an
- Abrupt termination).
-
- To cancel all server push streams related to a request, the client
- may issue a stream error (Section 2.4.2) with error code CANCEL on
- the associated-stream-id. By cancelling that stream, the server MUST
- immediately stop sending frames for any streams with
- in-association-to for the original stream.
-
- If the server sends a HEADER frame containing duplicate headers with
- a previous HEADERS frame for the same stream, the client must issue a
- stream error (Section 2.4.2) with error code PROTOCOL ERROR.
-
- If the server sends a HEADERS frame after sending a data frame for
- the same stream, the client MAY ignore the HEADERS frame. Ignoring
- the HEADERS frame after a data frame prevents handling of HTTP's
- trailing headers
- (http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.40).

-4. Design Rationale and Notes
-
- Authors' notes: The notes in this section have no bearing on the SPDY
- protocol as specified within this document, and none of these notes
- should be considered authoritative about how the protocol works.
- However, these notes may prove useful in future debates about how to
- resolve protocol ambiguities or how to evolve the protocol going
- forward. They may be removed before the final draft.
-
-4.1. Separation of Framing Layer and Application Layer
-
- Readers may note that this specification sometimes blends the framing
- layer (Section 2) with requirements of a specific application - HTTP
- (Section 3). This is reflected in the request/response nature of the
- streams, the definition of the HEADERS and compression contexts which
- are very similar to HTTP, and other areas as well.
-
- This blending is intentional - the primary goal of this protocol is
- to create a low-latency protocol for use with HTTP. Isolating the
- two layers is convenient for description of the protocol and how it
- relates to existing HTTP implementations. However, the ability to
- reuse the SPDY framing layer is a non goal.
-
-4.2. Error handling - Framing Layer
-
- Error handling at the SPDY layer splits errors into two groups: Those
- that affect an individual SPDY stream, and those that do not.
-
- When an error is confined to a single stream, but general framing is
- in tact, SPDY attempts to use the RST_STREAM as a mechanism to
- invalidate the stream but move forward without aborting the
- connection altogether.
-
- For errors occuring outside of a single stream context, SPDY assumes
- the entire session is hosed. In this case, the endpoint detecting
- the error should initiate a connection close.
-
-4.3. One Connection Per Domain
-
- SPDY attempts to use fewer connections than other protocols have
- traditionally used. The rationale for this behavior is because it is
- very difficult to provide a consistent level of service (e.g. TCP
- slow-start), prioritization, or optimal compression when the client
- is connecting to the server through multiple channels.
-
- Through lab measurements, we have seen consistent latency benefits by
- using fewer connections from the client. The overall number of
- packets sent by SPDY can be as much as 40% less than HTTP. Handling
-
-
-
-Belshe & Peon Expires August 4, 2012 [Page 40]
-
-Internet-Draft SPDY Feb 2012
-
-
- large numbers of concurrent connections on the server also does
- become a scalability problem, and SPDY reduces this load.
-
- The use of multiple connections is not without benefit, however.
- Because SPDY multiplexes multiple, independent streams onto a single
- stream, it creates a potential for head-of-line blocking problems at
- the transport level. In tests so far, the negative effects of head-
- of-line blocking (especially in the presence of packet loss) is
- outweighed by the benefits of compression and prioritization.
-
-4.4. Fixed vs Variable Length Fields
-
- SPDY favors use of fixed length 32bit fields in cases where smaller,
- variable length encodings could have been used. To some, this seems
- like a tragic waste of bandwidth. SPDY choses the simple encoding
- for speed and simplicity.
-
- The goal of SPDY is to reduce latency on the network. The overhead
- of SPDY frames is generally quite low. Each data frame is only an 8
- byte overhead for a 1452 byte payload (~0.6%). At the time of this
- writing, bandwidth is already plentiful, and there is a strong trend
- indicating that bandwidth will continue to increase. With an average
- worldwide bandwidth of 1Mbps, and assuming that a variable length
- encoding could reduce the overhead by 50%, the latency saved by using
- a variable length encoding would be less than 100 nanoseconds. More
- interesting are the effects when the larger encodings force a packet
- boundary, in which case a round-trip could be induced. However, by
- addressing other aspects of SPDY and TCP interactions, we believe
- this is completely mitigated.
-
-4.5. Compression Context(s)
-
- When isolating the compression contexts used for communicating with
- multiple origins, we had a few choices to make. We could have
- maintained a map (or list) of compression contexts usable for each
- origin. The basic case is easy - each HEADERS frame would need to
- identify the context to use for that frame. However, compression
- contexts are not cheap, so the lifecycle of each context would need
- to be bounded. For proxy servers, where we could churn through many
- contexts, this would be a concern. We considered using a static set
- of contexts, say 16 of them, which would bound the memory use. We
- also considered dynamic contexts, which could be created on the fly,
- and would need to be subsequently destroyed. All of these are
- complicated, and ultimately we decided that such a mechanism creates
- too many problems to solve.
-
- Alternatively, we've chosen the simple approach, which is to simply
- provide a flag for resetting the compression context. For the common
-
-
-
-Belshe & Peon Expires August 4, 2012 [Page 41]
-
-Internet-Draft SPDY Feb 2012
-
-
- case (no proxy), this fine because most requests are to the same
- origin and we never need to reset the context. For cases where we
- are using two different origins over a single SPDY session, we simply
- reset the compression state between each transition.
-
-4.6. Unidirectional streams
-
- Many readers notice that unidirectional streams are both a bit
- confusing in concept and also somewhat redundant. If the recipient
- of a stream doesn't wish to send data on a stream, it could simply
- send a SYN_REPLY with the FLAG_FIN bit set. The FLAG_UNIDIRECTIONAL
- is, therefore, not necessary.
-
- It is true that we don't need the UNIDIRECTIONAL markings. It is
- added because it avoids the recipient of pushed streams from needing
- to send a set of empty frames (e.g. the SYN_STREAM w/ FLAG_FIN) which
- otherwise serve no purpose.
-
-4.7. Data Compression
-
- Generic compression of data portion of the streams (as opposed to
- compression of the headers) without knowing the content of the stream
- is redundant. There is no value in compressing a stream which is
- already compressed. Because of this, SPDY does allow data
- compression to be optional. We included it because study of existing
- websites shows that many sites are not using compression as they
- should, and users suffer because of it. We wanted a mechanism where,
- at the SPDY layer, site administrators could simply force compression
- - it is better to compress twice than to not compress.
-
- Overall, however, with this feature being optional and sometimes
- redundant, it is unclear if it is useful at all. We will likely
- remove it from the specification.
-
-4.8. Server Push
-
- A subtle but important point is that server push streams must be
- declared before the associated stream is closed. The reason for this
- is so that proxies have a lifetime for which they can discard
- information about previous streams. If a pushed stream could
- associate itself with an already-closed stream, then endpoints would
- not have a specific lifecycle for when they could disavow knowledge
- of the streams which went before.

-
-5. Security Considerations
-
-5.1. Use of Same-origin constraints
-
- This specification uses the same-origin policy [RFC6454] in all cases
- where verification of content is required.
-
-5.2. HTTP Headers and SPDY Headers
-
- At the application level, HTTP uses name/value pairs in its headers.
- Because SPDY merges the existing HTTP headers with SPDY headers,
- there is a possibility that some HTTP applications already use a
- particular header name. To avoid any conflicts, all headers
- introduced for layering HTTP over SPDY are prefixed with ":". ":" is
- not a valid sequence in HTTP header naming, preventing any possible
- conflict.
-
-5.3. Cross-Protocol Attacks
-
- By utilizing TLS, we believe that SPDY introduces no new cross-
- protocol attacks. TLS encrypts the contents of all transmission
- (except the handshake itself), making it difficult for attackers to
- control the data which could be used in a cross-protocol attack.
-
-5.4. Server Push Implicit Headers
-
- Pushed resources do not have an associated request. In order for
- existing HTTP cache control validations (such as the Vary header) to
- work, however, all cached resources must have a set of request
- headers. For this reason, browsers MUST be careful to inherit
- request headers from the associated stream for the push. This
- includes the 'Cookie' header.

-
-
-6. Privacy Considerations
-
-6.1. Long Lived Connections
-
- SPDY aims to keep connections open longer between clients and servers
- in order to reduce the latency when a user makes a request. The
- maintenance of these connections over time could be used to expose
- private information. For example, a user using a browser hours after
- the previous user stopped using that browser may be able to learn
- about what the previous user was doing. This is a problem with HTTP
- in its current form as well, however the short lived connections make
- it less of a risk.
-
-6.2. SETTINGS frame
-
- The SPDY SETTINGS frame allows servers to store out-of-band
- transmitted information about the communication between client and
- server on the client. Although this is intended only to be used to
- reduce latency, renegade servers could use it as a mechanism to store
- identifying information about the client in future requests.
-
- Clients implementing privacy modes, such as Google Chrome's
- "incognito mode", may wish to disable client-persisted SETTINGS
- storage.
-
- Clients MUST clear persisted SETTINGS information when clearing the
- cookies.
-
- TODO: Put range maximums on each type of setting to limit
- inappropriate uses.

+/**
+ * Just includes the NEW definitions for the NG-API.
+ * Note that we do not indicate which of the OLD APIs
+ * simply need to be kept vs. deprecated.
+ *
+ *
+ * The goal is to provide a basis for discussion!
+ * Little of this is implemented yet.
+ *
+ * Main goals:
+ * - simplify application callbacks by splitting header/upload/post
+ * functionality currently provided by calling the same
+ * MHD_AccessHandlerCallback 3+ times into separate callbacks.
+ * - keep the API very simple for simple requests, but allow
+ * more complex logic to be incrementally introduced
+ * (via new struct MHD_Action construction)
+ * - avoid repeated scans for URL matches via the new
+ * struct MHD_Action construction
+ * - provide default logarithmic implementation of URL scan
+ * => reduce strcmp(url) from >= 3n operations to "log n"
+ * per request.
+ * - better types, in particular avoid varargs for options
+ * - make it harder to pass inconsistent options
+ * - combine options and flags into more uniform API (at least
+ * exterally!)
+ * - simplify API use by using sane defaults (benefiting from
+ * breaking backwards compatibility) and making all options
+ * really optional, and where applicable avoid having options
+ * where the default works if nothing is specified
+ * - simplify API by moving rarely used http_version into
+ * MHD_request_get_information()
+ * - avoid 'int' for MHD_YES/MHD_NO by introducing `enum MHD_Bool`
+ * - improve terminology by eliminating confusion between
+ * 'request' and 'connection'
+ * - prepare API for having multiple TLS backends
+ * - use more consistent prefixes for related functions
+ * by using MHD_subject_verb_object naming convention, also
+ * at the same time avoid symbol conflict with legacy names
+ * (so we can have one binary implementing old and new
+ * library API at the same time via compatibility layer).
+ * - make it impossible to queue a response at the wrong time
+ * - make it impossible to suspend a connection/request at the
+ * wrong time (improves thread-safety)
+ * - make it clear which response status codes are "properly"
+ * supported (include the descriptive string) by using an enum;
+ * - simplify API for common-case of one-shot responses by
+ * eliminating need for destroy response in most cases;
+ *
+ * TODO:
+ * - varargs in upgrade is still there and ugly (and not even used!)
+ * - migrate event loop apis (get fdset, timeout, MHD_run(), etc.)

- * @file microspdy.h
- * @brief public interface to libmicrospdy
- * @author Andrey Uzunov
- * @author Christian Grothoff
- *
- * All symbols defined in this header start with SPDY_. libmisrospdy is a small
- * SPDY daemon library. The application can start multiple daemons
- * and they are independent.<p>
- *
- * The header file defines various constants used by the SPDY and the HTTP protocol.
- * This does not mean that the lib actually interprets all of these
- * values. Not everything is implemented. The provided constants are exported as a convenience
- * for users of the library. The lib does not verify that provided
- * HTTP headers and if their values conform to the SPDY protocol,
- * it only checks if the required headers for the SPDY requests and
- * responses are provided.<p>
- *
- * The library uses just a single thread.<p>
- *
- * Before including "microspdy.h" you should add the necessary
- * includes to define the types used in this file (which headers are needed may
- * depend on your platform; for possible suggestions consult
- * "platform.h" in the libmicrospdy distribution).<p>
- *
- * All of the functions returning SPDY_YES/SPDY_NO return
- * SPDY_INPUT_ERROR when any of the parameters are invalid, e.g.
- * required parameter is NULL.<p>
- *
- * The library does not check if anything at the application layer --
- * requests and responses -- is correct. For example, it
- * is up to the user to check if a client is sending HTTP body but the
- * method is GET.<p>
- *
- * The SPDY flow control is just partially implemented: the receiving
- * window is updated, and the client is notified, to prevent a client
- * from stop sending POST body data, for example.

+ * cannot be generated; instead, MHD will always produce "HTTP/1.1 101
+ * Switching Protocols" (if the response code 101 is used).

+ * processes new connections, processes any timed-out connection, and does
+ * other things required to run webserver.
+ * Once all connections are processed, function returns.
+ *
+ * This function is useful for quick and simple (lazy) webserver implementation
+ * if application needs to run a single thread only and does not have any other
+ * network activity.
+ *
+ * This function calls MHD_get_timeout() internally and use returned value as
+ * maximum wait time if it less than value of @a millisec parameter.
+ *
+ * It is expected that the "external" socket polling function is not used in
+ * conjunction with this function unless the @a millisec is set to zero.
+ *
+ * @param daemon the daemon to run
+ * @param millisec the maximum time in milliseconds to wait for network and
+ * other events. Note: there is no guarantee that function
+ * blocks for the specified amount of time. The real processing
+ * time can be shorter (if some data or connection timeout
+ * comes earlier) or longer (if data processing requires more
+ * time, especially in user callbacks).
+ * If set to '0' then function does not block and processes
+ * only already available data (if any).
+ * If set to '-1' then function waits for events
+ * indefinitely (blocks until next network activity or
+ * connection timeout).
+ * @return #MHD_YES on success, #MHD_NO if this
+ * daemon was not started with the right

+ *
+ * If @a mqop allows both RFC 2069 (MHD_DIGEST_AUTH_QOP_NONE) and QOP with
+ * value, then response is formed like if MHD_DIGEST_AUTH_QOP_NONE bit was
+ * not set, because such response should be backward-compatible with RFC 2069.
+ *
+ * If @a mqop allows only MHD_DIGEST_AUTH_MULT_QOP_NONE, then the response is
+ * formed in strict accordance with RFC 2069 (no 'qop', no 'userhash', no
+ * 'charset'). For better compatibility with clients, it is recommended (but
+ * not required) to set @a domain to NULL in this mode.
+ *
+ * @param connection the MHD connection structure
+ * @param realm the realm presented to the client
+ * @param opaque the string for opaque value, can be NULL, but NULL is
+ * not recommended for better compatibility with clients;
+ * the recommended format is hex or Base64 encoded string
+ * @param domain the optional space-separated list of URIs for which the
+ * same authorisation could be used, URIs can be in form
+ * "path-absolute" (the path for the same host with initial slash)
+ * or in form "absolute-URI" (the full path with protocol), in
+ * any case client may assume that URI is in the same "protection
+ * space" if it starts with any of values specified here;
+ * could be NULL (clients typically assume that the same
+ * credentials could be used for any URI on the same host)
+ * @param response the reply to send; should contain the "access denied"
+ * body; note that this function sets the "WWW Authenticate"
+ * header and that the caller should not do this;
+ * the NULL is tolerated
+ * @param signal_stale set to #MHD_YES if the nonce is stale to add 'stale=true'
+ * to the authentication header, this instructs the client
+ * to retry immediately with the new nonce and the same
+ * credentials, without asking user for the new password
+ * @param mqop the QOP to use
+ * @param malgo3 digest algorithm to use, MHD selects; if several algorithms
+ * are allowed then MD5 is preferred (currently, may be changed
+ * in next versions)
+ * @param userhash_support if set to non-zero value (#MHD_YES) then support of
+ * userhash is indicated, the client may provide
+ * hash("username:realm") instead of username in
+ * clear text;
+ * note that clients are allowed to provide the username
+ * in cleartext even if this parameter set to non-zero;
+ * when userhash is used, application must be ready to
+ * identify users by provided userhash value instead of
+ * username; see #MHD_digest_auth_calc_userhash() and
+ * #MHD_digest_auth_calc_userhash_hex()
+ * @param prefer_utf8 if not set to #MHD_NO, parameter 'charset=UTF-8' is

- *
- * Equivalent code is available from RSA Data Security, Inc.
- * This code has been tested against that, and is equivalent,

- * To compute the message digest of a chunk of bytes, declare an
- * MD5Context structure, pass it to MD5Init, call MD5Update as
- * needed on buffers full of bytes, and then call MD5Final, which
- * will fill a supplied 16-byte array with the digest.

- * @file proxy.c
- * @brief Translates incoming SPDY requests to http server on localhost.
- * Uses libcurl.
- * No error handling for curl requests.
- * TODO:
- * - test all options!
- * - don't abort on lack of memory
- * - Correct recapitalizetion of header names before giving the headers
- * to curl.
- * - curl does not close sockets when connection is closed and no
- * new sockets are opened (they stay in CLOSE_WAIT)
- * - add '/' when a user requests http://example.com . Now this is a bad
- * request
- * - curl returns 0 or 1 ms for timeout even when nothing will be done;
- * thus the loop uses CPU for nothing
