+ command's main() function rather than searching the $PATH and calling
+ exec on another file (which is much slower).
+
+ This disables that optimization, so toybox will run external commands
+ even when it has a built-in version of that command. This requires
+ toybox symlinks to be installed in the $PATH, or re-invoking the
+ "toybox" multiplexer command by name.
+

+
+config TOYBOX_MUSL_NOMMU_IS_BROKEN
+ bool "Workaround for musl-libc breakage on nommu systems."
+ default n
+ help
+ When using musl-libc on a nommu system, you'll need to say "y" here.
+
+ Although uclibc lets you detect support for things like fork() and
+ daemon() at compile time, musl intentionally includes broken versions
+ that always return -ENOSYS on nommu systems, and goes out of its way
+ to prevent any cross-compile compatible compile-time probes for a
+ nommu system.
+
+ Musl does this despite the fact that a nommu system can't even run
+ standard ELF binaries, and requires specially packaged executables.
+ (You can't even check a #define to see that you're building against
+ musl, due to its maintainer's policy that musl never has bugs that
+ require workarounds.)
+
+ So our only choice is to manually provide a musl nommu bug workaround
+ you can manually select to enable (larger, slower) nommu support with
+ musl.
+
+ You don't need this for uClibc, we have a compile time probe that
+ autodetects nommu support there.

+Toybox: all-in-one Linux command line.
+
+--- Getting started
+
+You can download static binaries for various targets from:
+
+ http://landley.net/toybox/bin
+
+The special name "." indicates the current directory (just like ".." means
+the parent directory), and you can run a program that isn't in the $PATH by
+specifying a path to it, so this should work:
+
+ wget http://landley.net/toybox/bin/toybox-x86_64
+ chmod +x toybox-x86_64
+ ./toybox-x86_64 echo hello world
+
+--- Building toybox
+
+Type "make help" for build instructions.
+
+Toybox uses the "make menuconfig; make; make install" idiom same as
+the Linux kernel. Usually you want something like:
+
+ make defconfig
+ make
+ make install
+
+Or maybe:
+
+ LDFLAGS="--static" CROSS_COMPILE=armv5l- make defconfig toybox
+ PREFIX=/path/to/root/filesystem/bin make install_flat
+
+The file "configure" defines default values for many environment
+variables that control the toybox build; if you set a value for any of
+these, your value is used instead of the default in that file.
+
+The CROSS_COMPILE argument above is optional, the default builds a version of
+toybox to run on the current machine. Cross compiling requires an appropriately
+prefixed cross compiler toolchain, several example toolchains are available at:
+
+ http;//landley.net/aboriginal/bin
+
+For the "CROSS_COMPILE=armv5l-" example above, download
+cross-compiler-armv5l.tar.bz2, extract it, and add its "bin" subdirectory to
+your $PATH. (And yes, the trailing - is significant, because the prefix
+includes a dash.)
+
+For more about cross compiling, see:
+
+ http://landley.net/writing/docs/cross-compiling.html
+ http://landley.net/aboriginal/architectures.html
+
+For a more thorough description of the toybox build process, see
+http://landley.net/toybox/code.html#building
+
+--- Using toybox
+
+The toybox build produces a multicall binary, a "swiss-army-knife" program
+that acts differently depending on the name it was called by (cp, mv, cat...).
+Installing toybox adds symlinks for each command name to the $PATH.
+
+The special "toybox" command treats its first argument as the command to run.
+With no arguments, it lists available commands. This allows you to use toybox
+without installing it. This is the only command that can have an arbitrary
+suffix (hence "toybox-armv5l").
+
+The "help" command provides information about each command (ala "help cat").
+
+--- Configuring toybox
+
+It works like the Linux kernel: allnoconfig, defconfig, and menuconfig edit
+a ".config" file that selects which features to include in the resulting
+binary. You can save and re-use your .config file, although may want to
+run "make oldconfig" to re-run the dependency resolver when migrating to
+new versions.
+
+The maximum sane configuration is "make defconfig": allyesconfig isn't
+recommended for toybox because it enables unfinished commands and debug code.
+
+--- Creating a Toybox-based Linux system
+
+Toybox is not a complete operating system, it's a program that runs under
+an operating system. Booting a simple system to a shell prompt requires
+three packages: an operating system kernel (Linux*) to drive the hardware,
+one or more programs for the system to run (toybox), and a C library ("libc")
+to tie them together (toybox has been tested with musl, uClibc, glibc,
+and bionic).
+
+The C library is part of a "toolchain", which is an integrated suite
+of compiler, assembler, and linker, plus the standard headers and libraries
+necessary to build C programs. (And miscellaneous binaries like nm and objdump.)
+
+Static linking (with the --static option) copies the shared library contents
+into the program, resulting in larger but more portable programs, which
+can run even if they're the only file in the filesystem. Otherwise,
+the "dynamically" linked programs require the library files to be present on
+the target system ("man ldd" and "man ld.so" for details).
+
+An example toybox-based system is Aboriginal Linux:
+
+ http://landley.net/aboriginal/about.html
+
+That's designed to run under qemu, emulating several different hardware
+architectures (x86, x86-64, arm, mips, sparc, powerpc, sh4). Each toybox
+release is regression tested by building Linux From Scratch under this
+toybox-based system on each supported architecture, using QEMU to emulate
+big and little endian systems with different word size and alignment
+requirements. (The eventual goal is to replace Linux From Scratch with
+the Android Open Source Project.)
+
+* Or something providing the same API such as FreeBSD's Linux emulation layer.

+

+ outline: http://landley.net/talks/celf-2015.txt
+
+--- Contributing
+
+The three important URLs for communicating with the toybox project are:
+
+ web page: http://landley.net/toybox
+
+ mailing list: http://lists.landley.net/listinfo.cgi/toybox-landley.net
+
+ git repo: http://github.com/landley/toybox
+
+The maintainer prefers patches be sent to the mailing list. If you use git,
+the easy thing to do is:
+
+ git format-patch -1 $HASH
+
+Then send a file attachment. The list holds messages from non-subscribers
+for moderation, but I usually get to them in a day or two.
+
+Although I do accept pull requests on github, I download the patches and
+apply them with "git am" (which avoids gratuitous merge commits). Closing
+the pull request is then the submitter's responsibility.
+
+If I haven't responded to your patch after one week, feel free to remind
+me of it.
+
+Android's policy for toybox patches is that non-build patches should go
+upstream first (into vanilla toybox, with discussion on the toybox mailing
+list) and then be pulled into android's toybox repo from there. (They
+generally resync on fridays). The exception is patches to their build scripts
+(Android.mk and the checked-in generated/* files) which go directly to AOSP.
+
+--- Code of conduct
+
+We're using twitter's https://engineering.twitter.com/opensource/code-of-conduct
+except email rob@landley.net with complaints.
+
+(Yes, I try to pay more attention to marginalized programmers, which somehow
+manages to include 51% of the population. If somebody has to be three times as
+good to get half the recognition, why WOULDN'T you adjust for that?)

(Use the p command to output matched lines.)\n-r Use extended regular expression syntax.\n-E Alias for -r.\n-s Treat input files separately (implied by -i)\n\nA SCRIPT is a series of one or more COMMANDs separated by newlines or\nsemicolons. All -e SCRIPTs are concatenated together as if separated\nby newlines, followed by all lines from -f SCRIPT_FILEs, in order.\nIf no -e or -f SCRIPTs are specified, the first argument is the SCRIPT.\n\nEach COMMAND may be preceded by an address which limits the command to\napply only to the specified line(s). Commands without an address apply to\nevery line. Addresses are of the form:\n\n [ADDRESS[,ADDRESS]]COMMAND\n\nThe ADDRESS may be a decimal line number (starting at 1), a /regular\nexpression/ within a pair of forward slashes, or the character \"$\" which\nmatches the last line of input. (In -s or -i mode this matches the last\nline of each file, otherwise just the last line of the last file.) A single\naddress matches one line, a pair of comma separated addresses match\neverything from the first address to the second address (inclusive). If\nboth addresses are regular expressions, more than one range of lines in\neach file can match.\n\nREGULAR EXPRESSIONS in sed are started and ended by the same character\n(traditionally / but anything except a backslash or a newline works).\nBackslashes may be used to escape the delimiter if it occurs in the\nregex, and for the usual printf escapes (\\abcefnrtv and octal, hex,\nand unicode). An empty regex repeats the previous one. ADDRESS regexes\n(above) require the first delimeter to be escaped with a backslash when\nit isn't a forward slash (to distinguish it from the COMMANDs below).\n\nSed mostly operates on individual lines one at a time. It reads each line,\nprocesses it, and either writes it to the output or discards it before\nreading the next line. Sed can remember one additional line in a separate\nbuffer (using the h, H, g, G, and x commands), and can read the next line\nof input early (using the n and N command), but other than that command\nscripts operate on individual lines of text.\n\nEach COMMAND starts with a single character. The following commands take\nno arguments:\n\n { Start a new command block, continuing until a corresponding \"}\".\n Command blocks may nest. If the block has an address, commands within\n the block are only run for lines within the block's address range.\n\n } End command block (this command cannot have an address)\n\n d Delete this line and move on to the next one\n (ignores remaining COMMANDs)\n\n D Delete one line of input and restart command SCRIPT (same as \"d\"\n unless you've glued lines together with \"N\" or similar)\n\n g Get remembered line (overwriting current line)\n\n G Get remembered line (appending to current line)\n\n h Remember this line (overwriting remembered line)\n\n H Remember this line (appending to remembered line, if any)\n\n l Print line, escaping \\abfrtv (but not newline), octal escaping other\n nonprintable characters, wrapping lines to terminal width with a\n backslash, and appending $ to actual end of line.\n\n n Print default output and read next line, replacing current line\n (If no next line available, quit processing script)\n\n N Append next line of input to this line, separated by a newline\n (This advances the line counter for address matching and \"=\", if no\n next line available quit processing script without default output)\n\n p Print this line\n\n P Print this line up to first newline (from \"N\")\n\n q Quit (print default output, no more commands processed or lines read)\n\n x Exchange this line with remembered line (overwrite in both directions)\n\n = Print the current line number (followed by a newline)\n\nThe following commands (may) take an argument. The \"text\" arguments (to\nthe \"a\", \"b\", and \"c\" commands) may end with an unescaped \"\\\" to append\nthe next line (for which leading whitespace is not skipped), and also\ntreat \";\" as a literal character (use \"\\;\" instead).\n\n a [text] Append text to output before attempting to read next line\n\n b [label] Branch, jumps to :label (or with no label, to end of SCRIPT)\n\n c [text] Delete line, output text at end of matching address range\n (ignores remaining COMMANDs)\n\n i [text] Print text\n\n r [file] Append contents of file to output before attempting to read\n next line.\n\n s/S/R/F Search for regex S, replace matched text with R using flags F.\n The first character after the \"s\" (anything but newline or\n backslash) is the delimiter, escape with \\ to use normally.\n\n The replacement text may contain \"&\" to substitute the matched\n text (escape it with backslash for a literal &), or \\1 through\n \\9 to substitute a parenthetical subexpression in the regex.\n You can also use the normal backslash escapes such as \\n and\n a backslash at the end of the line appends the next line.\n\n The flags are:\n\n [0-9] A number, substitute only that occurrence of pattern\n g Global, substitute all occurrences of pattern\n i Ignore case when matching\n p Print the line if match was found and replaced\n w [file] Write (append) line to file if match replaced\n\n t [label] Test, jump to :label only if an \"s\" command found a match in\n this line since last test (replacing with same text counts)\n\n T [label] Test false, jump only if \"s\" hasn't found a match.\n\n w [file] Write (append) line to file\n\n y/old/new/ Change each character in 'old' to corresponding character\n in 'new' (with standard backslash escapes, delimiter can be\n any repeated character except \\ or \\n)\n\n : [label] Labeled target for jump commands\n\n # Comment, ignore rest of this line of SCRIPT\n\nDeviations from posix: allow extended regular expressions with -r,\nediting in place with -i, separate with -s, printf escapes in text, line\ncontinuations, semicolons after all commands, 2-address anywhere an\naddress is allowed, \"T\" command, multiline continuations for [abc],\n\\; to end [abc] argument before end of line.\n\n"

+This is a snapshot of linux 2.6.12 kconfig as washed through busybox and
+further modified by Rob Landley.
+
+Way back when I tried to push my local changes to kconfig upstream
+in 2005 https://lwn.net/Articles/161086/
+and 2006 http://lkml.iu.edu/hypermail/linux/kernel/0607.0/1805.html
+and 2007 http://lkml.iu.edu/hypermail/linux/kernel/0707.1/1741.html
+each of which spawned long "I think you should go do this and this and this
+but I'm not going to lift a finger personally" threads from the kernel
+developers. Twice I came back a year later to see if there was any interest
+in what I _had_ done, and the third thread was the longest of the lot but
+no code was merged as a result.
+
+*shrug* That's the linux-kernel community for you. I had an easier time
+than the author of squashfs, who spent 5 years actively trying to get his code
+merged, finally quitting his job to spend an unpaid year working on upstreaming
+squashfs _after_ after every major Linux distro had been locally carrying it
+for years. No really, here's where he wrote about it himself:
+
+https://lwn.net/Articles/563578/
+
+This code is _going_away_. Rewriting it is low priority, but removing it is a
+checklist item for the 1.0 toybox release. This directory contains the only
+GPL code left in the tree, and none of its code winds up in the resulting
+binary. It's just an editor that reads our Config.in files to update the top
+level .config file; you can edit they by hand if you really want to.

+/*
+ * Changes by Clifford Wolf (god@clifford.at)
+ *
+ * [ 1998-06-13 ]
+ *
+ * *) A bugfix for the Page-Down problem
+ *
+ * *) Formerly when I used Page Down and Page Up, the cursor would be set
+ * to the first position in the menu box. Now lxdialog is a bit
+ * smarter and works more like other menu systems (just have a look at
+ * it).
+ *
+ * *) Formerly if I selected something my scrolling would be broken because
+ * lxdialog is re-invoked by the Menuconfig shell script, can't
+ * remember the last scrolling position, and just sets it so that the
+ * cursor is at the bottom of the box. Now it writes the temporary file
+ * lxdialog.scrltmp which contains this information. The file is
+ * deleted by lxdialog if the user leaves a submenu or enters a new
+ * one, but it would be nice if Menuconfig could make another "rm -f"
+ * just to be sure. Just try it out - you will recognise a difference!
+ *
+ * [ 1998-06-14 ]
+ *
+ * *) Now lxdialog is crash-safe against broken "lxdialog.scrltmp" files
+ * and menus change their size on the fly.
+ *
+ * *) If for some reason the last scrolling position is not saved by
+ * lxdialog, it sets the scrolling so that the selected item is in the
+ * middle of the menu box, not at the bottom.
+ *
+ * 02 January 1999, Michael Elizabeth Chastain (mec@shout.net)
+ * Reset 'scroll' to 0 if the value from lxdialog.scrltmp is bogus.
+ * This fixes a bug in Menuconfig where using ' ' to descend into menus
+ * would leave mis-synchronized lxdialog.scrltmp files lying around,
+ * fscanf would read in 'scroll', and eventually that value would get used.

+"Overview\n"
+"--------\n"
+"Some features may be built directly into the project.\n"
+"Some may be made into loadable runtime modules. Some features\n"
+"may be completely removed altogether. There are also certain\n"
+"parameters which are not really features, but must be\n"
+"entered in as decimal or hexadecimal numbers or possibly text.\n"
+"\n"
+"Menu items beginning with [*], <M> or [ ] represent features\n"
+"configured to be built in, modularized or removed respectively.\n"
+"Pointed brackets <> represent module capable features.\n"
+"\n"
+"To change any of these features, highlight it with the cursor\n"
+"keys and press <Y> to build it in, <M> to make it a module or\n"
+"<N> to removed it. You may also press the <Space Bar> to cycle\n"
+"through the available options (ie. Y->N->M->Y).\n"
+"\n"
+"Some additional keyboard hints:\n"
+"\n"
+"Menus\n"
+"----------\n"
+"o Use the Up/Down arrow keys (cursor keys) to highlight the item\n"
+" you wish to change or submenu wish to select and press <Enter>.\n"
+" Submenus are designated by \"--->\".\n"
+"\n"
+" Shortcut: Press the option's highlighted letter (hotkey).\n"
+" Pressing a hotkey more than once will sequence\n"
+" through all visible items which use that hotkey.\n"
+"\n"
+" You may also use the <PAGE UP> and <PAGE DOWN> keys to scroll\n"
+" unseen options into view.\n"
+"\n"
+"o To exit a menu use the cursor keys to highlight the <Exit> button\n"
+" and press <ENTER>.\n"
+"\n"
+" Shortcut: Press <ESC><ESC> or <E> or <X> if there is no hotkey\n"
+" using those letters. You may press a single <ESC>, but\n"
+" there is a delayed response which you may find annoying.\n"
+"\n"
+" Also, the <TAB> and cursor keys will cycle between <Select>,\n"
+" <Exit> and <Help>\n"
+"\n"
+"o To get help with an item, use the cursor keys to highlight <Help>\n"
+" and Press <ENTER>.\n"
+"\n"
+" Shortcut: Press <H> or <?>.\n"
+"\n"
+"\n"
+"Radiolists (Choice lists)\n"
+"-----------\n"
+"o Use the cursor keys to select the option you wish to set and press\n"
+" <S> or the <SPACE BAR>.\n"
+"\n"
+" Shortcut: Press the first letter of the option you wish to set then\n"
+" press <S> or <SPACE BAR>.\n"
+"\n"
+"o To see available help for the item, use the cursor keys to highlight\n"
+" <Help> and Press <ENTER>.\n"
+"\n"
+" Shortcut: Press <H> or <?>.\n"
+"\n"
+" Also, the <TAB> and cursor keys will cycle between <Select> and\n"
+" <Help>\n"
+"\n"
+"\n"
+"Data Entry\n"
+"-----------\n"
+"o Enter the requested information and press <ENTER>\n"
+" If you are entering hexadecimal values, it is not necessary to\n"
+" add the '0x' prefix to the entry.\n"
+"\n"
+"o For help, use the <TAB> or cursor keys to highlight the help option\n"
+" and press <ENTER>. You can try <TAB><H> as well.\n"
+"\n"
+"\n"
+"Text Box (Help Window)\n"
+"--------\n"
+"o Use the cursor keys to scroll up/down/left/right. The VI editor\n"
+" keys h,j,k,l function here as do <SPACE BAR> and <B> for those\n"
+" who are familiar with less and lynx.\n"
+"\n"
+"o Press <E>, <X>, <Enter> or <Esc><Esc> to exit.\n"

+"Alternate Configuration Files\n"
+"-----------------------------\n"
+"Menuconfig supports the use of alternate configuration files for\n"
+"those who, for various reasons, find it necessary to switch\n"
+"between different configurations.\n"
+"\n"
+"At the end of the main menu you will find two options. One is\n"
+"for saving the current configuration to a file of your choosing.\n"
+"The other option is for loading a previously saved alternate\n"
+"configuration.\n"
+"\n"
+"Even if you don't use alternate configuration files, but you\n"
+"find during a Menuconfig session that you have completely messed\n"
+"up your settings, you may use the \"Load Alternate...\" option to\n"
+"restore your previously saved settings from \".config\" without\n"
+"restarting Menuconfig.\n"
+"\n"
+"Other information\n"
+"-----------------\n"
+"If you use Menuconfig in an XTERM window make sure you have your\n"
+"$TERM variable set to point to a xterm definition which supports color.\n"
+"Otherwise, Menuconfig will look rather bad. Menuconfig will not\n"
+"display correctly in a RXVT window because rxvt displays only one\n"
+"intensity of color, bright.\n"
+"\n"
+"Menuconfig will display larger menus on screens or xterms which are\n"
+"set to display more than the standard 25 row by 80 column geometry.\n"
+"In order for this to work, the \"stty size\" command must be able to\n"
+"display the screen's current row and column geometry. I STRONGLY\n"
+"RECOMMEND that you make sure you do NOT have the shell variables\n"
+"LINES and COLUMNS exported into your environment. Some distributions\n"
+"export those variables via /etc/profile. Some ncurses programs can\n"
+"become confused when those variables (LINES & COLUMNS) don't reflect\n"
+"the true screen size.\n"
+"\n"
+"Optional personality available\n"
+"------------------------------\n"
+"If you prefer to have all of the options listed in a single\n"
+"menu, rather than the default multimenu hierarchy, run the menuconfig\n"
+"with MENUCONFIG_MODE environment variable set to single_menu. Example:\n"
+"\n"
+"make MENUCONFIG_MODE=single_menu menuconfig\n"
+"\n"
+"<Enter> will then unroll the appropriate category, or enfold it if it\n"
+"is already unrolled.\n"
+"\n"
+"Note that this mode can eventually be a little more CPU expensive\n"
+"(especially with a larger number of unrolled categories) than the\n"
+"default mode.\n"
+"\n"
+"Different color themes available\n"
+"--------------------------------\n"
+"It is possible to select different color themes using the variable\n"
+"MENUCONFIG_COLOR. To select a theme use:\n"
+"\n"
+"make MENUCONFIG_COLOR=<theme> menuconfig\n"
+"\n"
+"Available themes are\n"
+" mono => selects colors suitable for monochrome displays\n"
+" blackbg => selects a color scheme with black background\n"
+" classic => theme with blue background. The classic look\n"
+" bluetitle => a LCD friendly version of classic. (default)\n"

+/* args.c - Command line argument parsing.
+ *
+ * Copyright 2006 Rob Landley <rob@landley.net>
+ */
+
+// NOTE: If option parsing segfaults, switch on TOYBOX_DEBUG in menuconfig.
+
+// Enabling TOYBOX_DEBUG in .config adds syntax checks to option string parsing
+// which aren't needed in the final code (your option string is hardwired and
+// should be correct when you ship), but are useful for development.
+
+#include "toys.h"
+
+// Design goals:
+// Don't use getopt() out of libc.
+// Don't permute original arguments (screwing up ps/top output).
+// Integrated --long options "(noshort)a(along)b(blong1)(blong2)"
+
+/* This uses a getopt-like option string, but not getopt() itself. We call
+ * it the get_opt string.
+ *
+ * Each option in the get_opt string corresponds to a bit position in the
+ * return value. The rightmost argument is (1<<0), the next to last is (1<<1)
+ * and so on. If the option isn't seen in argv[], its bit remains 0.
+ *
+ * Options which have an argument fill in the corresponding slot in the global
+ * union "this" (see generated/globals.h), which it treats as an array of longs
+ * (note that sizeof(long)==sizeof(pointer) is guaranteed by LP64).
+ *
+ * You don't have to free the option strings, which point into the environment
+ * space. List objects should be freed by main() when command_main() returns.
+ *
+ * Example:
+ * Calling get_optflags() when toys.which->options="ab:c:d" and
+ * argv = ["command", "-b", "fruit", "-d", "walrus"] results in:
+ *
+ * Changes to struct toys:
+ * toys.optflags = 5 (I.E. 0101 so -b = 4 | -d = 1)
+ * toys.optargs[0] = "walrus" (leftover argument)
+ * toys.optargs[1] = NULL (end of list)
+ * toys.optc = 1 (there was 1 leftover argument)
+ *
+ * Changes to union this:
+ * this[0]=NULL (because -c didn't get an argument this time)
+ * this[1]="fruit" (argument to -b)
+ */
+
+// What you can put in a get_opt string:
+// Any otherwise unused character (all letters, unprefixed numbers) specify
+// an option that sets a flag. The bit value is the same as the binary digit
+// if you string the option characters together in order.
+// So in "abcdefgh" a = 128, h = 1
+//
+// Suffixes specify that this option takes an argument (stored in GLOBALS):
+// Note that pointer and long are always the same size, even on 64 bit.
+// : plus a string argument, keep most recent if more than one
+// * plus a string argument, appended to a list
+// # plus a signed long argument
+// <LOW - die if less than LOW
+// >HIGH - die if greater than HIGH
+// =DEFAULT - value if not specified
+// - plus a signed long argument defaulting to negative (say + for positive)
+// . plus a double precision floating point argument (with CFG_TOYBOX_FLOAT)
+// Chop this option out with USE_TOYBOX_FLOAT() in option string
+// Same <LOW>HIGH=DEFAULT as #
+// @ plus an occurrence counter (which is a long)
+// (longopt)
+// | this is required. If more than one marked, only one required.
+// ; long option's argument is optional (can only be supplied with --opt=)
+// ^ Stop parsing after encountering this argument
+// " " (space char) the "plus an argument" must be separate
+// I.E. "-j 3" not "-j3". So "kill -stop" != "kill -s top"
+//
+// At the beginning of the get_opt string (before any options):
+// ^ stop at first nonoption argument
+// <0 die if less than # leftover arguments (default 0)
+// >9 die if > # leftover arguments (default MAX_INT)
+// ? Allow unknown arguments (pass them through to command).
+// & first argument has imaginary dash (ala tar/ps)
+// If given twice, all arguments have imaginary dash
+//
+// At the end: [groups] of previously seen options
+// - Only one in group (switch off) [-abc] means -ab=-b, -ba=-a, -abc=-c
+// + Synonyms (switch on all) [+abc] means -ab=-abc, -c=-abc
+// ! More than one in group is error [!abc] means -ab calls error_exit()
+// primarily useful if you can switch things back off again.
+
+// Notes from getopt man page
+// - and -- cannot be arguments.
+// -- force end of arguments
+// - is a synonym for stdin in file arguments
+// -abcd means -a -b -c -d (but if -b takes an argument, then it's -a -b cd)

+# If equal to "fail", stop after first failed test.
+# SKIP - do not perform this test (this is set by "optionflag")

+# Brief: Some cursery coverage tests of ifconfig...
+# Note: requires permissions to run modprobe and all ifconfig options
+# Commands used: grep, grep -i, ip link, ip tuntap, wc -l
+#
+# Possible improvements:
+# 1. Verify the dummy interface actually has the modified characteristics
+# instead of relying on ifconfig output
+# 2. Introduce more error cases, to verify ifconfig fails gracefully
+# 3. Do more complex calls to ifconfig, while mixing the order of the
+# arguments
+# 4. Cover more ifconfig options:
+# hw ether|infiniband ADDRESS - set LAN hardware address (AA:BB:CC...)
+# txqueuelen LEN - number of buffered packets before output blocks
+# Obsolete fields included for historical purposes:
+# irq|io_addr|mem_start ADDR - micromanage obsolete hardware
+# outfill|keepalive INTEGER - SLIP analog dialup line quality monitoring
+# metric INTEGER - added to Linux 0.9.10 with comment "never used", still true

+ bool "ifconfig"
+ default y
+ help
+ usage: ifconfig [-a] [INTERFACE [ACTION...]]
+
+ Display or configure network interface.
+
+ With no arguments, display active interfaces. First argument is interface
+ to operate on, one argument by itself displays that interface.
+
+ -a Show all interfaces, not just active ones
+
+ Additional arguments are actions to perform on the interface:
+
+ ADDRESS[/NETMASK] - set IPv4 address (1.2.3.4/5)
+ default - unset ipv4 address
+ add|del ADDRESS[/PREFIXLEN] - add/remove IPv6 address (1111::8888/128)
+ up - enable interface
+ down - disable interface
+
+ netmask|broadcast|pointopoint ADDRESS - set more IPv4 characteristics
+ hw ether|infiniband ADDRESS - set LAN hardware address (AA:BB:CC...)
+ txqueuelen LEN - number of buffered packets before output blocks
+ mtu LEN - size of outgoing packets (Maximum Transmission Unit)
+
+ Flags you can set on an interface (or -remove by prefixing with -):
+ arp - don't use Address Resolution Protocol to map LAN routes
+ promisc - don't discard packets that aren't to this LAN hardware address
+ multicast - force interface into multicast mode if the driver doesn't
+ allmulti - promisc for multicast packets
+
+ Obsolete fields included for historical purposes:
+ irq|io_addr|mem_start ADDR - micromanage obsolete hardware
+ outfill|keepalive INTEGER - SLIP analog dialup line quality monitoring
+ metric INTEGER - added to Linux 0.9.10 with comment "never used", still true

+
+Commands in this directory are external submissions awaiting review and/or
+cleanup before being "promoted" to one of the other directories.
+
+Code in this directory may or may not work, some of the commands here are
+unfinished stubs, others just need a more thorough inspection than we've had
+time for yet. Everything in here defaults to "n" in defconfig.
+
+Outside of this directory, several commands (and some library code) have
+TODO annotations.
+
+This directory should go away before the 1.0 release. It's just a staging
+area so code submissions don't get lost while awaiting more thorough (and
+very time consuming) scrutiny as described in www/cleanup.html.

+ * Divergence from posix: replace obsolete/patented "compress" with mutiplexer.
+ * (gzip already replaces "uncompress".)
+ *
+ * See RFCs 1950 (zlib), 1951 (deflate), and 1952 (gzip)

+ Evaluate expression and print result. For example, "expr 1 + 2".
+
+ The supported operators are (grouped from highest to lowest priority):
+
+ ( ) : * / % + - != <= < >= > = & |
+
+ Each constant and operator must be a separate command line argument.
+ All operators are infix, meaning they expect a constant (or expression
+ that resolves to a constant) on each side of the operator. Operators of
+ the same priority (within each group above) are evaluated left to right.
+ Parentheses may be used (as separate arguments) to elevate the priority
+ of expressions.
+
+ Calling expr from a command shell requires a lot of \( or '*' escaping
+ to avoid interpreting shell control characters.
+
+ The & and | operators are logical (not bitwise) and may operate on
+ strings (a blank string is "false"). Comparison operators may also
+ operate on strings (alphabetical sort).
+
+ Constants may be strings or integers. Comparison, logical, and regex
+ operators may operate on strings (a blank string is "false"), other
+ operators require integers.

+ Search directories for matching files.
+ Default: search "." match all -print all matches.
+
+ -H Follow command line symlinks -L Follow all symlinks
+
+ Match filters:
+ -name PATTERN filename with wildcards -iname case insensitive -name
+ -path PATTERN path name with wildcards -ipath case insensitive -path
+ -user UNAME belongs to user UNAME -nouser user ID not known
+ -group GROUP belongs to group GROUP -nogroup group ID not known
+ -perm [-/]MODE permissions (-=min /=any) -prune ignore contents of dir
+ -size N[c] 512 byte blocks (c=bytes) -xdev only this filesystem
+ -links N hardlink count -atime N accessed N days ago
+ -ctime N created N days ago -mtime N modified N days ago
+ -newer FILE newer mtime than FILE -mindepth # at least # dirs down
+ -depth ignore contents of dir -maxdepth # at most # dirs down
+ -inum N inode number N -empty empty files and dirs
+ -type [bcdflps] (block, char, dir, file, symlink, pipe, socket)
+
+ Numbers N may be prefixed by a - (less than) or + (greater than):
+
+ Combine matches with:
+ !, -a, -o, ( ) not, and, or, group expressions
+
+ Actions:
+ -print Print match with newline -print0 Print match with null
+ -exec Run command with path -execdir Run command in file's dir
+ -ok Ask before exec -okdir Ask before execdir
+ -delete Remove matching file/dir
+
+ Commands substitute "{}" with matched file. End with ";" to run each file,

+ *
+ * Copyright 2015 Rob Landley <rob@landley.net>
+ *
+ * See http://pubs.opengroup.org/onlinepubs/9699919799/utilities/ps.html
+ * And http://kernel.org/doc/Documentation/filesystems/proc.txt Table 1-4
+ * And linux kernel source fs/proc/array.c function do_task_stat()
+ *
+ * Deviations from posix: no -n because /proc/self/wchan exists; we use -n to
+ * mean "show numeric users and groups" instead.
+ * Posix says default output should have field named "TTY" but if you "-o tty"
+ * the same field should be called "TT" which is _INSANE_ and I'm not doing it.
+ * Similarly -f outputs USER but calls it UID (we call it USER).
+ * It also says that -o "args" and "comm" should behave differently but use
+ * the same title, which is not the same title as the default output. (No.)
+ * Select by session id is -s not -g.
+ *
+ * Posix defines -o ADDR as "The address of the process" but the process
+ * start address is a constant on any elf system with mmu. The procps ADDR
+ * field always prints "-" with an alignment of 1, which is why it has 11
+ * characters left for "cmd" in in 80 column "ps -l" mode. On x86-64 you
+ * need 12 chars, leaving nothing for cmd: I.E. posix 2008 ps -l mode can't
+ * be sanely implemented on 64 bit Linux systems. In procps there's ps -y
+ * which changes -l by removing the "F" column and swapping RSS for ADDR,
+ * leaving 9 chars for cmd, so we're using that as our -l output.
+ *
+ * Added a bunch of new -o fields posix doesn't mention, and we don't
+ * label "ps -o command,args,comm" as "COMMAND COMMAND COMMAND". We don't
+ * output argv[0] unmodified for -o comm or -o args (but procps violates
+ * posix for -o comm anyway, it's stat[2] not argv[0]).
+ *
+ * Note: iotop is STAYROOT so it can read other process's /proc/$PID/io
+ * files (why they're not globally readable when the rest of proc
+ * data is...?) and get a global I/O picture. Normal top is NOT,
+ * even though you can -o AIO there, to give sysadmins the option
+ * to reduce security exposure.)
+ *
+ * TODO: ps aux (att & bsd style "ps -ax" vs "ps ax" behavior difference)
+ * TODO: switch -fl to -y
+ * TODO: thread support /proc/$d/task/%d/stat (and -o stat has "l")
+ * TODO: iotop: Window size change: respond immediately. Why not padding
+ * at right edge? (Not adjusting to screen size at all? Header wraps?)
+ * TODO: top: thread support and SMP
+ * TODO: pgrep -f only searches the amount of cmdline that fits in toybuf.

+
+config SED
+ bool "sed"
+ default y
+ help
+ usage: sed [-inrE] [-e SCRIPT]...|SCRIPT [-f SCRIPT_FILE]... [FILE...]
+
+ Stream editor. Apply one or more editing SCRIPTs to each line of input
+ (from FILE or stdin) producing output (by default to stdout).
+
+ -e add SCRIPT to list
+ -f add contents of SCRIPT_FILE to list
+ -i Edit each file in place.
+ -n No default output. (Use the p command to output matched lines.)
+ -r Use extended regular expression syntax.
+ -E Alias for -r.
+ -s Treat input files separately (implied by -i)
+
+ A SCRIPT is a series of one or more COMMANDs separated by newlines or
+ semicolons. All -e SCRIPTs are concatenated together as if separated
+ by newlines, followed by all lines from -f SCRIPT_FILEs, in order.
+ If no -e or -f SCRIPTs are specified, the first argument is the SCRIPT.
+
+ Each COMMAND may be preceded by an address which limits the command to
+ apply only to the specified line(s). Commands without an address apply to
+ every line. Addresses are of the form:
+
+ [ADDRESS[,ADDRESS]]COMMAND
+
+ The ADDRESS may be a decimal line number (starting at 1), a /regular
+ expression/ within a pair of forward slashes, or the character "$" which
+ matches the last line of input. (In -s or -i mode this matches the last
+ line of each file, otherwise just the last line of the last file.) A single
+ address matches one line, a pair of comma separated addresses match
+ everything from the first address to the second address (inclusive). If
+ both addresses are regular expressions, more than one range of lines in
+ each file can match.
+
+ REGULAR EXPRESSIONS in sed are started and ended by the same character
+ (traditionally / but anything except a backslash or a newline works).
+ Backslashes may be used to escape the delimiter if it occurs in the
+ regex, and for the usual printf escapes (\abcefnrtv and octal, hex,
+ and unicode). An empty regex repeats the previous one. ADDRESS regexes
+ (above) require the first delimeter to be escaped with a backslash when
+ it isn't a forward slash (to distinguish it from the COMMANDs below).
+
+ Sed mostly operates on individual lines one at a time. It reads each line,
+ processes it, and either writes it to the output or discards it before
+ reading the next line. Sed can remember one additional line in a separate
+ buffer (using the h, H, g, G, and x commands), and can read the next line
+ of input early (using the n and N command), but other than that command
+ scripts operate on individual lines of text.
+
+ Each COMMAND starts with a single character. The following commands take
+ no arguments:
+
+ { Start a new command block, continuing until a corresponding "}".
+ Command blocks may nest. If the block has an address, commands within
+ the block are only run for lines within the block's address range.
+
+ } End command block (this command cannot have an address)
+
+ d Delete this line and move on to the next one
+ (ignores remaining COMMANDs)
+
+ D Delete one line of input and restart command SCRIPT (same as "d"
+ unless you've glued lines together with "N" or similar)
+
+ g Get remembered line (overwriting current line)
+
+ G Get remembered line (appending to current line)
+
+ h Remember this line (overwriting remembered line)
+
+ H Remember this line (appending to remembered line, if any)
+
+ l Print line, escaping \abfrtv (but not newline), octal escaping other
+ nonprintable characters, wrapping lines to terminal width with a
+ backslash, and appending $ to actual end of line.
+
+ n Print default output and read next line, replacing current line
+ (If no next line available, quit processing script)
+
+ N Append next line of input to this line, separated by a newline
+ (This advances the line counter for address matching and "=", if no
+ next line available quit processing script without default output)
+
+ p Print this line
+
+ P Print this line up to first newline (from "N")
+
+ q Quit (print default output, no more commands processed or lines read)
+
+ x Exchange this line with remembered line (overwrite in both directions)
+
+ = Print the current line number (followed by a newline)
+
+ The following commands (may) take an argument. The "text" arguments (to
+ the "a", "b", and "c" commands) may end with an unescaped "\" to append
+ the next line (for which leading whitespace is not skipped), and also
+ treat ";" as a literal character (use "\;" instead).
+
+ a [text] Append text to output before attempting to read next line
+
+ b [label] Branch, jumps to :label (or with no label, to end of SCRIPT)
+
+ c [text] Delete line, output text at end of matching address range
+ (ignores remaining COMMANDs)
+
+ i [text] Print text
+
+ r [file] Append contents of file to output before attempting to read
+ next line.
+
+ s/S/R/F Search for regex S, replace matched text with R using flags F.
+ The first character after the "s" (anything but newline or
+ backslash) is the delimiter, escape with \ to use normally.
+
+ The replacement text may contain "&" to substitute the matched
+ text (escape it with backslash for a literal &), or \1 through
+ \9 to substitute a parenthetical subexpression in the regex.
+ You can also use the normal backslash escapes such as \n and
+ a backslash at the end of the line appends the next line.
+
+ The flags are:
+
+ [0-9] A number, substitute only that occurrence of pattern
+ g Global, substitute all occurrences of pattern
+ i Ignore case when matching
+ p Print the line if match was found and replaced
+ w [file] Write (append) line to file if match replaced
+
+ t [label] Test, jump to :label only if an "s" command found a match in
+ this line since last test (replacing with same text counts)
+
+ T [label] Test false, jump only if "s" hasn't found a match.
+
+ w [file] Write (append) line to file
+
+ y/old/new/ Change each character in 'old' to corresponding character
+ in 'new' (with standard backslash escapes, delimiter can be
+ any repeated character except \ or \n)
+
+ : [label] Labeled target for jump commands
+
+ # Comment, ignore rest of this line of SCRIPT
+
+ Deviations from posix: allow extended regular expressions with -r,
+ editing in place with -i, separate with -s, printf escapes in text, line
+ continuations, semicolons after all commands, 2-address anywhere an
+ address is allowed, "T" command, multiline continuations for [abc],
+ \; to end [abc] argument before end of line.

+<html><head><title>What is toybox?</title>
+<!--#include file="header.html" -->
+
+<h2><a name="what" />What is toybox?</h2>
+
+<p>Toybox combines many common Linux command line utilities together into
+a single <a href=license.html>BSD-licensed</a> executable. It's simple, small, fast, and reasonably
+standards-compliant (<a href=http://opengroup.org/onlinepubs/9699919799>POSIX-2008</a> and <a href=http://refspecs.linuxfoundation.org/LSB_4.1.0>LSB 4.1</a>).</p>
+
+<p>Toybox's main goal is to make Android
+<a href=http://landley.net/aboriginal/about.html#selfhost>self-hosting</a>
+by improving Android's command line utilities so it can
+build an installable Android Open Source Project image
+entirely from source under a stock Android system. After a talk at the 2013
+Embedded Linux Conference explaining this plan
+(<a href=http://landley.net/talks/celf-2013.txt>outline</a>,
+<a href=https://www.youtube.com/watch?v=SGmtP5Lg_t0>video</a>), Google
+<a href=https://lwn.net/Articles/629362/>merged toybox into AOSP</a> and
+began shipping toybox in Android Mashmallow.</p>
+
+<p>Toybox aims to provide one quarter of a theoretical "minimal native
+development environment", which is the simplest Linux system capable of
+rebuilding itself from source code and then building
+<a href=http://linuxfromscratch.org/lfs>Linux From Scratch</a>
+and the <a href=https://source.android.com>Android Open Source Project</a>
+under the result. In theory, this should only require four packages:
+1) a set of posix-ish command line utilities,
+2) a compiler<a name="1_back"></a><sup><font size=-3><a href=#1>[1]</a></font></sup>,
+3) a C library, and 4) a kernel. This provides a reproducible and auditable
+base system, which with the addition of a few convienciences (vi, top,
+shell command line history...) can provide a usable interactive experience
+rather than just a headless build server.</p>
+
+<b><h2><a name="why" />Why is toybox?</h2></b>
+
+<p>The <a href=http://landley.net/talks/celf-2015.txt>2015 toybox talk</a>
+starts with links to three previous talks on the history and motivation of
+the project: "Why Toybox", "Why Public Domain", and "Why did I do
+Aboriginal Linux (which led me here)?". If you're really bored,
+there's even a half-finished
+<a href=http://landley.net/aboriginal/history.html>a history page</a>.</p>
+
+<p>The toybox maintainer's earlier minimal self-hosting system project,
+<a href=http://landley.net/aboriginal/about.html>Aboriginal Linux</a>,
+got its minimal native development environment down to seven packages in
+its 1.0 release (busybox, uClibc, gcc, binutils, make, bash, and linux)
+and built Linux From Scratch under the result. That project
+<a href=http://landley.net/aboriginal/history.html>was the reason</a>
+toybox's maintainer became busybox maintainer, having done so
+much work to extend busybox to replace all the gnu tools in a Linux From
+Scratch build that the previous maintainer handed over the project (to
+spend more time on buildroot).</p>
+
+<p>Despite the maintainer's history with busybox, toybox is a fresh
+from-scratch implementation under an
+<a href=https://source.android.com/source/licenses.html>android-compatible</a>
+<a href=license.html>license</a>. Busybox predates Android, but has never
+shipped with Android due to the license. As long as we're starting over anyway,
+we can do a better job.</p>
+
+<p>These days, toybox is replacing busybox
+in Aboriginal Linux one command at a time, and each toybox release is
+regression tested by building Aboriginal Linux with it, then building
+Linux From Scratch under the result with the new toybox commands.
+The list of commands remaining is tracked <a href=roadmap.html#dev_env>in
+the roadmap</a>, and the replacing busybox in Aboriginal Linux is
+one of the main goals for toybox' 1.0 release.</p>
+
+<p>Building LFS requres fewer commands than building AOSP, which has a lot more
+<a href=http://source.android.com/source/initializing.html>build
+prerequisites</a>. In theory some of those can be built from source
+as external packages (we're clearly not including our own java implementation),
+but some early prerequisites may need to be added to bootstrap AOSP far enough
+to build them (such as a read-only version of "git":
+how does repo download the AOSP source otherwise?)
+<a name="2_back"></a><sup><font size=-3><a href=#2>[2]</a></font></sup></p>
+
+<b><h2><a name="status" />What commands are planned/implemented in toybox?</h2></b>
+
+<p>The current list of commands implemented by toybox is on the
+<a href=status.html>status page</a>, which is updated each release.
+There is also a <a href=roadmap.html>roadmap</a> listing all planned commands
+for the 1.0 release and the reasons for including them.</p>
+
+<p>In general, configuring toybox with "make defconfig" enables all the commands
+compete enough to be useful. Configuring "allyesconfig" enables partially
+implemented commands as well, along with debugging features.</p>
+
+<b><h3>Relevant Standards</h3></b>
+
+<p>Most commands are implemented according to POSIX-2008 (I.E.
+<a href=http://opengroup.org/onlinepubs/9699919799/idx/utilities.html>The
+Single Unix Specification version 4</a>) where applicable. This does not mean
+that toybox is implementing every SUSv4 utility: some such as SCCS and ed are
+obsolete, while others such as c99 are outside the scope of the project.
+Toybox also isn't implementing full internationalization support: it should be
+8-bit clean and handle UTF-8, but otherwise we leave this to X11 and higher
+layers. And some things (like $CDPATH support in "cd") await a good
+explanation of why to bother with them. (POSIX provides an important
+frame of reference, but is not an infallable set of commandments to be blindly
+obeyed. We do try to document our deviations from it in the comment section
+at the start of each command under toys/posix.)</p>
+
+<p>The other major sources of commands are the Linux man pages, the
+Linux Standard Base, and testing the behavior of existing command
+implementations (although not generally looking at their
+source code), including the commands in Android's toolbox. SUSv4 does not
+include many basic commands such as "mount", "init", and "mke2fs", which are

+<p>It's <a href=toycans-big.jpg>carefully stacked soda cans</a>. Specifically,

+stacked to spell out the binary values of the ascii string "Toybox", with
+null terminator at the bottom. (The big picture's on it's side because
+the camera was held sideways to get a better shot.)</p>
+
+<p>No, it's not photoshopped, I actually had these cans until a coworker
+who Totally Did Not Get It <sup><font size=-3><a href=http://www.timesys.com>tm</a></font></sup> threw them out one day after I'd gone home,
+thinking they were recycling. (I still have two of each kind, but
+Pepsi One seems discontinued and Coke Zero switched its can color
+from black to grey, presumably in celebration. It was fun while it lasted...)</p>

+<b><h2>Footnotes</h2></b>
+
+<p><a name="1" /><a href="#1_back">[1]</a> Ok, most toolchains (gcc, llvm, pcc, libfirm...)
+are multiple packages, but the maintainer of toybox used to maintain a
+<a href=http://landley.net/tinycc>fork of tinycc</a> (an integrated
+compiler/assembler/linker which once upon a
+time did <a href=http://bellard.org/tcc/tccboot.html>build a bootable linux
+kernel</a> before its original developer abandoned the project),
+and has <a href=http://landley.net/hg/qcc/file/tip/todo/todo.txt>vague plans</a> of <a href=http://landley.net/qcc>trying
+again someday</a>. The compiler toolchain is _conceptually_ one package,
+implementable as a single multicall binary acting like make, cc, as, ld, cpp,
+strip, readelf, nm, objdump, and so on as necessary. It's just the existing
+packages that do this <strike>kinda suck</strike> don't. (In theory "make"
+belongs in qcc, in practice llvm hasn't got its own make so toybox probably
+needs to add it after 1.0 to eliminate another gpl build prerequite from
+AOSP.)</p>
+
+<p><a name="2" /><a href="#2_back">[2]</a>
+The dividing line is
+"Is there an acceptably licensed version Android can ship, or do we have
+to write one?" Since android is not "GNU/Linux" in any way, we need to
+clean out all traces of gnu software from its build to get a clean
+self-hosting system.</p>

+<h1>Cleaning up the toybox code.</h1>
+
+<p>Toybox <a href=http://landley.net/notes.html#31-03-2013>hasn't always</a>
+taken proper advantage of external contributions</a>.
+Lots of people want to help, but their contributions languish out of tree
+or in the "pending" directory, awaiting cleanup.</p>
+
+<p>Toybox's design goals require simpler, tighter, and more explicit code
+than most other implementations, among other reasons to allow better security
+auditing. Writing "another" implementation of standard command line tools
+isn't very interesting, they should be _better_ implementations.
+Unfortunately, this means existing, working commands often take more effort to
+clean up to Toybox's standards than writing a new one from scratch, not
+because they don't work, but because we aim for an unusual level of polish.</p>
+
+<p>In hopes of teaching more people how to do this
+cleanup work, I've started breaking cleanup changes into smaller chunks and
+posting explanations of each change to the mailing list.
+Below are indexes of such cleanup series. Each commit and post are meant to
+be read together: each description explains what the corresponding patch
+was trying to accomplish.</p>
+
+<p>Line/byte totals of completed series are given for scale, but the point
+of this work is simplicity and compactness, not size per se.</p>
+
+<p>(Note: mercurial's web viewer doesn't follow renames, so although each
+command name links to a commit list with the bulk of the changes, it may
+not include the final version of each file moved from the "pending"
+directory to its final location. The summaries link the initial and cleaned
+versions of each file when giving line counts.)</p>

+<h1>General advice and/or policy.</h1>
+
+<p>The <a href=design.html>design of toybox</a> page and the coding
+style section at the start of the <a href=code.html>source code walkthrough</a>
+don't cover everything. Here are some
+links to mailing list messages that cover various programming topics
+not directly related to a specific cleanup series:</p>
+
+<ul>
+<li><a href=http://lists.landley.net/pipermail/toybox-landley.net/2013-April/000850.html>Error messages and internationalization.</a></li>
+<li><a href=http://lists.landley.net/pipermail/toybox-landley.net/2013-April/000891.html>Why not "const"?</a> (Exception: global variables
+outside of GLOBALS can be static const, to go in rodata instead of data.
+This means the pages can be shared between instances.)</li>
+<li><a href=http://lkml.indiana.edu/hypermail/linux/kernel/1308.3/03890.html>Why not "bool"?</a> (explanation from Linus Torvalds)</li>

+sight does not really help readability."</a> -
+<a href=http://lkml.iu.edu/hypermail/linux/kernel/1407.1/00299.html>Pavel
+Machek</a></li>
+<li>"Infrastructure in search of a user" is a bad thing, so don't put code
+in lib/ that doesn't already have at least two users. Don't preemptively
+factor stuff out, it's easy enough to rewrite it uin future if it needs
+to change. The "extreme programming" fad called this "You Ain't Gonna
+Need It" (while inexplicably screaming at cans of Mountain Dew, back in the
+90's). Here's <a href=https://lwn.net/Articles/683745/>Linus Torvalds' take</a>.</li>

+
+<p>This is an example of cleaning up something most projects would be quite
+happy with. The initial submission of uuencode and uudecode was high
+quality code, written by a seasoned developer who did an excellent

+
+<p>This series describes a thorough cleanup that took a while to do.</p>
+
+<p>When ifconfig was submitted, it touched a half-dozen files. I glued it
+together into a single self-contained file, which needed a lot of
+cleanup. The final version is about 1/3 the size of the original.</p>

+<!--#include file="header.html" -->
+
+<p><h1><a name="style" /><a href="#style">Code style</a></h1></p>
+
+<p>The primary goal of toybox is _simple_ code. Keeping the code small is
+second, with speed and lots of features coming in somewhere after that.
+(For more on that, see the <a href=design.html>design</a> page.)</p>
+
+<p>A simple implementation usually takes up fewer lines of source code,
+meaning more code can fit on the screen at once, meaning the programmer can
+see more of it on the screen and thus keep more if in their head at once.
+This helps code auditing and thus reduces bugs. That said, sometimes being
+more explicit is preferable to being clever enough to outsmart yourself:
+don't be so terse your code is unreadable.</p>
+
+<p>Toybox has an actual coding style guide over on
+<a href=design.html#codestyle>the design page</a>, but in general we just
+want the code to be consistent.</p>
+
+<p><h1><a name="building" /><a href="#building">Building Toybox</a></h1></p>
+
+<p>Toybox is configured using the Kconfig language pioneered by the Linux
+kernel, and adopted by many other projects (uClibc, OpenEmbedded, etc).
+This generates a ".config" file containing the selected options, which
+controls which features are included when compiling toybox.</p>
+
+<p>Each configuration option has a default value. The defaults indicate the
+"maximum sane configuration", I.E. if the feature defaults to "n" then it
+either isn't complete or is a special-purpose option (such as debugging
+code) that isn't intended for general purpose use.</p>
+
+<p>For a more compact human-editable version .config files, you can use the
+<a href=http://landley.net/aboriginal/FAQ.html#dev_miniconfig>miniconfig</a>
+format.</p>
+
+<p>The standard build invocation is:</p>
+
+<ul>
+<li>make defconfig #(or menuconfig)</li>
+<li>make</li>
+<li>make install</li>
+</ul>
+
+<p>Type "make help" to see all available build options.</p>
+
+<p>The file "configure" contains a number of environment variable definitions
+which influence the build, such as specifying which compiler to use or where
+to install the resulting binaries. This file is included by the build, but
+accepts existing definitions of the environment variables, so it may be sourced
+or modified by the developer before building and the definitions exported
+to the environment will take precedence.</p>
+
+<p>(To clarify: ".config" lists the features selected by defconfig/menuconfig,
+I.E. "what to build", and "configure" describes the build and installation
+environment, I.E. "how to build it".)</p>
+
+<p>By default "make install" puts files in /usr/toybox. Adding this to the
+$PATH is up to you. The environment variable $PREFIX can change the
+install location, ala "PREFIX=/usr/local/bin make install".</p>
+
+<p>If you need an unstripped (debug) version of any of these binaries,
+look in generated/unstripped.</p>
+
+<p><h1><a name="running"><a href="#running">Running a command</a></h1></p>
+
+<h2>main</h2>
+
+<p>The toybox main() function is at the end of main.c at the top level. It has
+two possible codepaths, only one of which is configured into any given build
+of toybox.</p>
+
+<p>If CONFIG_SINGLE is selected, toybox is configured to contain only a single
+command, so most of the normal setup can be skipped. In this case the
+multiplexer isn't used, instead main() calls toy_singleinit() (also in main.c)
+to set up global state and parse command line arguments, calls the command's
+main function out of toy_list (in the CONFIG_SINGLE case the array has a single entry, no need to search), and if the function returns instead of exiting
+it flushes stdout (detecting error) and returns toys.exitval.</p>
+
+<p>When CONFIG_SINGLE is not selected, main() uses basename() to find the
+name it was run as, shifts its argument list one to the right so it lines up
+with where the multiplexer function expects it, and calls toybox_main(). This
+leverages the multiplexer command's infrastructure to find and run the
+appropriate command. (A command name starting with "toybox" will
+recursively call toybox_main(); you can go "./toybox toybox toybox toybox ls"
+if you want to...)</p>
+
+<h2>toybox_main</h2>
+
+<p>The toybox_main() function is also in main,c. It handles a possible
+--help option ("toybox --help ls"), prints the list of available commands if no
+arguments were provided to the multiplexer (or with full path names if any
+other option is provided before a command name, ala "toybox --list").
+Otherwise it calls toy_exec() on its argument list.</p>
+
+<p>Note that the multiplexer is the first entry in toy_list (the rest of the
+list is sorted alphabetically to allow binary search), so toybox_main can
+cheat and just grab the first entry to quickly set up its context without
+searching. Since all command names go through the multiplexer at least once
+in the non-TOYBOX_SINGLE case, this avoids a redundant search of
+the list.</p>
+
+<p>The toy_exec() function is also in main.c. It performs toy_find() to
+perform a binary search on the toy_list array to look up the command's
+entry by name and saves it in the global variable which, calls toy_init()
+to parse command line arguments and set up global state (using which->options),
+and calls the appropriate command's main() function (which->toy_main). On
+return it flushes all pending ansi FILE * I/O, detects if stdout had an
+error, and then calls xexit() (which uses toys.exitval).</p>
+
+<p><h1><a name="infrastructure" /><a href="#infrastructure">Infrastructure</a></h1></p>
+
+<p>The toybox source code is in following directories:</p>
+<ul>
+<li>The <a href="#top">top level directory</a> contains the file main.c (were
+execution starts), the header file toys.h (included by every command), and
+other global infrastructure.</li>
+<li>The <a href="#lib">lib directory</a> contains common functions shared by
+multiple commands:</li>
+<ul>
+<li><a href="#lib_lib">lib/lib.c</a></li>
+<li><a href="#lib_xwrap">lib/xwrap.c</a></li>
+<li><a href="#lib_llist">lib/llist.c</a></li>
+<li><a href="#lib_args">lib/args.c</a></li>
+<li><a href="#lib_dirtree">lib/dirtree.c</a></li>
+</ul>
+<li>The <a href="#toys">toys directory</a> contains the C files implementating
+each command. Currently it contains five subdirectories categorizing the
+commands: posix, lsb, other, example, and pending.</li>
+<li>The <a href="#scripts">scripts directory</a> contains the build and
+test infrastructure.</li>
+<li>The <a href="#kconfig">kconfig directory</a> contains the configuration
+infrastructure implementing menuconfig (copied from the Linux kernel).</li>
+<li>The <a href="#generated">generated directory</a> contains intermediate
+files generated from other parts of the source code.</li>
+</ul>
+
+<a name="adding" />
+<p><h1><a href="#adding">Adding a new command</a></h1></p>
+<p>To add a new command to toybox, add a C file implementing that command to
+one of the subdirectories under the toys directory. No other files need to
+be modified; the build extracts all the information it needs (such as command
+line arguments) from specially formatted comments and macros in the C file.
+(See the description of the <a href="#generated">"generated" directory</a>
+for details.)</p>
+
+<p>Currently there are five subdirectories under "toys", one for commands
+defined by the POSIX standard, one for commands defined by the Linux Standard
+Base, an "other" directory for commands not covered by an obvious standard,
+a directory of example commands (templates to use when starting new commands),
+and a "pending" directory of commands that need further review/cleanup
+before moving to one of the other directories (run these at your own risk,
+cleanup patches welcome).
+These directories are just for developer convenience sorting the commands,
+the directories are otherwise functionally identical. To add a new category,
+create the appropriate directory with a README file in it whose first line
+is the description menuconfig should use for the directory.)</p>
+
+<p>An easy way to start a new command is copy the file "toys/example/hello.c"
+to the name of the new command, and modify this copy to implement the new
+command (more or less by turning every instance of "hello" into the
+name of your command, updating the command line arguments, globals, and
+help data, and then filling out its "main" function with code that does
+something interesting).</p>
+
+<p>You could also start with "toys/example/skeleton.c", which provides a lot
+more example code (showing several variants of command line option
+parsing, how to implement multiple commands in the same file, and so on).
+But usually it's just more stuff to delete.</p>
+
+<p>Here's a checklist of steps to turn hello.c into another command:</p>
+
+<ul>
+<li><p>First "cp toys/example/hello.c toys/other/yourcommand.c" and open
+the new file in your preferred text editor.</p>
+<ul><li><p>Note that the
+name of the new file is significant: it's the name of the new command you're
+adding to toybox. The build includes all *.c files under toys/*/ whose
+names are a case insensitive match for an enabled config symbol. So
+toys/posix/cat.c only gets included if you have "CAT=y" in ".config".</p></li>
+</ul></p></li>
+
+<li><p>Change the one line comment at the top of the file (currently
+"hello.c - A hello world program") to describe your new file.</p></li>
+
+<li><p>Change the copyright notice to your name, email, and the current
+year.</p></li>
+
+<li><p>Give a URL to the relevant standards document, where applicable.
+(Sample links to SUSv4 and LSB are provided, feel free to link to other
+documentation or standards as appropriate.)</p></li>
+
+<li><p>Update the USE_YOURCOMMAND(NEWTOY(yourcommand,"blah",0)) line.
+The NEWTOY macro fills out this command's <a href="#toy_list">toy_list</a>
+structure. The arguments to the NEWTOY macro are:</p>
+
+<ol>
+<li><p>the name used to run your command</p></li>
+<li><p>the command line argument <a href="#lib_args">option parsing string</a> (0 if none)</p></li>
+<li><p>a bitfield of TOYFLAG values
+(defined in toys.h) providing additional information such as where your
+command should be installed on a running system, whether to blank umask
+before running, whether or not the command must run as root (and thus should
+retain root access if installed SUID), and so on.</p></li>
+</ol>
+</li>
+
+<li><p>Change the kconfig data (from "config YOURCOMMAND" to the end of the
+comment block) to supply your command's configuration and help
+information. The uppper case config symbols are used by menuconfig, and are
+also what the CFG_ and USE_() macros are generated from (see [TODO]). The
+help information here is used by menuconfig, and also by the "help" command to
+describe your new command. (See [TODO] for details.) By convention,
+unfinished commands default to "n" and finished commands default to "y",
+so "make defconfig" selects all finished commands. (Note, "finished" means
+"ready to be used", not that it'll never change again.)<p>
+
+<p>Each help block should start with a "usage: yourcommand" line explaining
+any command line arguments added by this config option. The "help" command
+outputs this text, and scripts/config2help.c in the build infrastructure
+collates these usage lines for commands with multiple configuration
+options when producing generated/help.h.</p>
+</li>
+
+<li><p>Change the "#define FOR_hello" line to "#define FOR_yourcommand" right
+before the "#include <toys.h>". (This selects the appropriate FLAG_ macros and
+does a "#define TT this.yourcommand" so you can access the global variables
+out of the space-saving union of structures. If you aren't using any command
+flag bits and aren't defining a GLOBAL block, you can delete this line.)</p></li>
+
+<li><p>Update the GLOBALS() macro to contain your command's global
+variables. If your command has no global variables, delete this macro.</p>
+
+<p>Variables in the GLOBALS() block are are stored in a space saving
+<a href="#toy_union">union of structures</a> format, which may be accessed
+using the TT macro as if TT were a global structure (so TT.membername).
+If you specified two-character command line arguments in
+NEWTOY(), the first few global variables will be initialized by the automatic
+argument parsing logic, and the type and order of these variables must
+correspond to the arguments specified in NEWTOY().
+(See <a href="#lib_args">lib/args.c</a> for details.)</p></li>
+
+<li><p>Rename hello_main() to yourcommand_main(). This is the main() function
+where execution of your command starts. Your command line options are
+already sorted into this.optflags, this.optargs, this.optc, and the GLOBALS()
+as appropriate by the time this function is called. (See
+<a href="#lib_args">get_optflags()</a> for details.)</p></li>
+
+<li><p>Switch on TOYBOX_DEBUG in menuconfig (toybox global settings menu)
+the first time you build and run your new command. If anything is wrong
+with your option string, that will give you error messages.</p>
+
+<p>Otherwise it'll just segfault without
+explanation when it falls off the end because it didn't find a matching
+end parantheses for a longopt, or you put a nonexistent option in a square
+bracket grouping... Since these kind of errors can only be caused by a
+developer, not by end users, we don't normally want runtime checks for
+them. Once you're happy with your option string, you can switch TOYBOX_DEBUG
+back off.</p></li>
+</ul>
+
+<a name="headers" /><h2><a href="#headers">Headers.</a></h2>
+
+<p>Commands generally don't have their own headers. If it's common code
+it can live in lib/, if it isn't put it in the command's .c file. (The line
+between implementing multiple commands in a C file via OLDTOY() to share
+infrastructure and moving that shared infrastructure to lib/ is a judgement
+call. Try to figure out which is simplest.)</p>
+
+<p>The top level toys.h should #include all the standard (posix) headers
+that any command uses. (Partly this is friendly to ccache and partly this
+makes the command implementations shorter.) Individual commands should only
+need to include nonstandard headers that might prevent that command from
+building in some context we'd care about (and thus requiring that command to
+be disabled to avoid a build break).</p>
+
+<p>Target-specific stuff (differences between compiler versions, libc versions,
+or operating systems) should be confined to lib/portability.h and
+lib/portability.c. (There's even some minimal compile-time environment probing
+that writes data to generated/portability.h, see scripts/genconfig.sh.)</p>
+
+<p>Only include linux/*.h headers from individual commands (not from other
+headers), and only if you really need to. Data that varies per architecture
+is a good reason to include a header. If you just need a couple constants
+that haven't changed since the 1990's, it's ok to #define them yourself or
+just use the constant inline with a comment explaining what it is. (A
+#define that's only used once isn't really helping.)</p>
+
+<p><a name="top" /><h1><a href="#top">Top level directory.</a></h1></p>
+
+<p>This directory contains global infrastructure.</p>
+
+<h3>toys.h</h3>
+<p>Each command #includes "toys.h" as part of its standard prolog. It
+may "#define FOR_commandname" before doing so to get some extra entries
+specific to this command.</p>
+
+<p>This file sucks in most of the commonly used standard #includes, so
+individual files can just #include "toys.h" and not have to worry about
+stdargs.h and so on. Individual commands still need to #include
+special-purpose headers that may not be present on all systems (and thus would
+prevent toybox from building that command on such a system with that command
+enabled). Examples include regex support, any "linux/" or "asm/" headers, mtab
+support (mntent.h and sys/mount.h), and so on.</p>
+
+<p>The toys.h header also defines structures for most of the global variables
+provided to each command by toybox_main(). These are described in
+detail in the description for main.c, where they are initialized.</p>
+
+<p>The global variables are grouped into structures (and a union) for space
+savings, to more easily track the amount of memory consumed by them,
+so that they may be automatically cleared/initialized as needed, and so
+that access to global variables is more easily distinguished from access to
+local variables.</p>
+
+<h3>main.c</h3>
+<p>Contains the main() function where execution starts, plus
+common infrastructure to initialize global variables and select which command
+to run. The "toybox" multiplexer command also lives here. (This is the
+only command defined outside of the toys directory.)</p>
+
+<p>Execution starts in main() which trims any path off of the first command
+name and calls toybox_main(), which calls toy_exec(), which calls toy_find()
+and toy_init() before calling the appropriate command's function from
+toy_list[] (via toys.which->toy_main()).
+If the command is "toybox", execution recurses into toybox_main(), otherwise
+the call goes to the appropriate commandname_main() from a C file in the toys
+directory.</p>
+
+<p>The following global variables are defined in main.c:</p>
+<ul>
+<a name="toy_list" />
+<li><p><b>struct toy_list toy_list[]</b> - array describing all the
+commands currently configured into toybox. The first entry (toy_list[0]) is
+for the "toybox" multiplexer command, which runs all the other built-in commands
+without symlinks by using its first argument as the name of the command to
+run and the rest as that command's argument list (ala "./toybox echo hello").
+The remaining entries are the commands in alphabetical order (for efficient
+binary search).</p>
+
+<p>This is a read-only array initialized at compile time by
+defining macros and #including generated/newtoys.h.</p>
+
+<p>Members of struct toy_list (defined in "toys.h") include:</p>
+<ul>
+<li><p>char *<b>name</b> - the name of this command.</p></li>
+<li><p>void (*<b>toy_main</b>)(void) - function pointer to run this
+command.</p></li>
+<li><p>char *<b>options</b> - command line option string (used by
+get_optflags() in lib/args.c to intialize toys.optflags, toys.optargs, and
+entries in the toy's GLOBALS struct). When this is NULL, no option
+parsing is done before calling toy_main().</p></li>
+<li><p>int <b>flags</b> - Behavior flags for this command. The following flags are currently understood:</p>
+
+<ul>
+<li><b>TOYFLAG_USR</b> - Install this command under /usr</li>
+<li><b>TOYFLAG_BIN</b> - Install this command under /bin</li>
+<li><b>TOYFLAG_SBIN</b> - Install this command under /sbin</li>
+<li><b>TOYFLAG_NOFORK</b> - This command can be used as a shell builtin.</li>
+<li><b>TOYFLAG_UMASK</b> - Call umask(0) before running this command.</li>
+<li><b>TOYFLAG_STAYROOT</b> - Don't drop permissions for this command if toybox is installed SUID root.</li>
+<li><b>TOYFLAG_NEEDROOT</b> - This command cannot function unless run with root access.</li>
+</ul>
+<br>
+
+<p>These flags are combined with | (or). For example, to install a command
+in /usr/bin, or together TOYFLAG_USR|TOYFLAG_BIN.</p>
+</ul>
+</li>
+
+<li><p><b>struct toy_context toys</b> - global structure containing information
+common to all commands, initializd by toy_init() and defined in "toys.h".
+Members of this structure include:</p>
+<ul>
+<li><p>struct toy_list *<b>which</b> - a pointer to this command's toy_list
+structure. Mostly used to grab the name of the running command
+(toys->which.name).</p>
+</li>
+<li><p>int <b>exitval</b> - Exit value of this command. Defaults to zero. The
+error_exit() functions will return 1 if this is zero, otherwise they'll
+return this value.</p></li>
+<li><p>char **<b>argv</b> - "raw" command line options, I.E. the original
+unmodified string array passed in to main(). Note that modifying this changes
+"ps" output, and is not recommended. This array is null terminated; a NULL
+entry indicates the end of the array.</p>
+<p>Most commands don't use this field, instead the use optargs, optflags,
+and the fields in the GLOBALS struct initialized by get_optflags().</p>
+</li>
+<li><p>unsigned <b>optflags</b> - Command line option flags, set by
+<a href="#lib_args">get_optflags()</a>. Indicates which of the command line options listed in
+toys->which.options occurred this time.</p>
+
+<p>The rightmost command line argument listed in toys->which.options sets bit
+1, the next one sets bit 2, and so on. This means the bits are set in the same
+order the binary digits would be listed if typed out as a string. For example,
+the option string "abcd" would parse the command line "-c" to set optflags to 2,
+"-a" would set optflags to 8, and "-bd" would set optflags to 6 (4|2).</p>
+
+<p>Only letters are relevant to optflags. In the string "a*b:c#d", d=1, c=2,
+b=4, a=8. Punctuation after a letter initializes global variables at the
+start of the GLOBALS() block (see <a href="#toy_union">union toy_union this</a>
+for details).</p>
+
+<p>The build infrastructure creates FLAG_ macros for each option letter,
+corresponding to the bit position, so you can check (toys.optflags & FLAG_x)
+to see if a flag was specified. (The correct set of FLAG_ macros is selected
+by defining FOR_mycommand before #including toys.h. The macros live in
+toys/globals.h which is generated by scripts/make.sh.)</p>
+
+<p>For more information on option parsing, see <a href="#lib_args">get_optflags()</a>.</p>
+
+</li>
+<li><p>char **<b>optargs</b> - Null terminated array of arguments left over
+after get_optflags() removed all the ones it understood. Note: optarg[0] is
+the first argument, not the command name. Use toys.which->name for the command
+name.</p></li>
+<li><p>int <b>optc</b> - Optarg count, equivalent to argc but for
+optargs[].<p></li>
+</ul>
+
+<a name="toy_union" />
+<li><p><b>union toy_union this</b> - Union of structures containing each
+command's global variables.</p>
+
+<p>Global variables are useful: they reduce the overhead of passing extra
+command line arguments between functions, they conveniently start prezeroed to
+save initialization costs, and the command line argument parsing infrastructure
+can also initialize global variables with its results.</p>
+
+<p>But since each toybox process can only run one command at a time, allocating
+space for global variables belonging to other commands you aren't currently
+running would be wasteful.</p>
+
+<p>Toybox handles this by encapsulating each command's global variables in
+a structure, and declaring a union of those structures with a single global
+instance (called "this"). The GLOBALS() macro contains the global
+variables that should go in the current command's global structure. Each
+variable can then be accessed as "this.commandname.varname".
+If you #defined FOR_commandname before including toys.h, the macro TT is
+#defined to this.commandname so the variable can then be accessed as
+"TT.variable". See toys/hello.c for an example.</p>
+
+<p>A command that needs global variables should declare a structure to
+contain them all, and add that structure to this union. A command should never
+declare global variables outside of this, because such global variables would
+allocate memory when running other commands that don't use those global
+variables.</p>
+
+<p>The first few fields of this structure can be intialized by <a href="#lib_args">get_optargs()</a>,
+as specified by the options field off this command's toy_list entry. See
+the get_optargs() description in lib/args.c for details.</p>
+</li>
+
+<li><b>char toybuf[4096]</b> - a common scratch space buffer guaranteed
+to start zeroed, so commands don't need to allocate/initialize their own.
+Any command is free to use this, and it should never be directly referenced
+by functions in lib/ (although commands are free to pass toybuf in to a
+library function as an argument).</li>
+
+<li><b>char libbuf[4096]</b> - like toybuf, but for use by common code in
+lib/*.c. Commands should never directly reference libbuf, and library
+could should nnever directly reference toybuf.</li>
+</ul>
+
+<p>The following functions are defined in main.c:</p>
+<ul>
+<li><p>struct toy_list *<b>toy_find</b>(char *name) - Return the toy_list
+structure for this command name, or NULL if not found.</p></li>
+<li><p>void <b>toy_init</b>(struct toy_list *which, char *argv[]) - fill out
+the global toys structure, calling get_optargs() if necessary.</p></li>
+<li><p>void <b>toy_exec</b>(char *argv[]) - Run a built-in command with
+arguments.</p>
+<p>Calls toy_find() on argv[0] (which must be just a command name
+without path). Returns if it can't find this command, otherwise calls
+toy_init(), toys->which.toy_main(), and exit() instead of returning.</p>
+
+<p>Use the library function xexec() to fall back to external executables
+in $PATH if toy_exec() can't find a built-in command. Note that toy_exec()
+does not strip paths before searching for a command, so "./command" will
+never match an internal command.</li>
+
+<li><p>void <b>toybox_main</b>(void) - the main function for the multiplexer
+command (I.E. "toybox"). Given a command name as its first argument, calls
+toy_exec() on its arguments. With no arguments, it lists available commands.
+If the first argument starts with "-" it lists each command with its default
+install path prepended.</p></li>
+
+</ul>
+
+<h3>Config.in</h3>
+
+<p>Top level configuration file in a stylized variant of
+<a href=http://kernel.org/doc/Documentation/kbuild/kconfig-language.txt>kconfig</a> format. Includes generated/Config.in.</p>
+
+<p>These files are directly used by "make menuconfig" to select which commands
+to build into toybox (thus generating a .config file), and by
+scripts/config2help.py to create generated/help.h.</p>
+
+<a name="generated" />
+<h1><a href="#generated">Temporary files:</a></h1>
+
+<p>There is one temporary file in the top level source directory:</p>
+<ul>
+<li><p><b>.config</b> - Configuration file generated by kconfig, indicating
+which commands (and options to commands) are currently enabled. Used
+to make generated/config.h and determine which toys/*/*.c files to build.</p>
+
+<p>You can create a human readable "miniconfig" version of this file using
+<a href=http://landley.net/aboriginal/new_platform.html#miniconfig>these
+instructions</a>.</p>
+</li>
+</ul>
+
+<p><h2>Directory generated/</h2></p>
+
+<p>The remaining temporary files live in the "generated/" directory,
+which is for files generated at build time from other source files.</p>
+
+<ul>
+<li><p><b>generated/Config.in</b> - Kconfig entries for each command, included
+from the top level Config.in. The help text here is used to generate
+help.h.</p>
+
+<p>Each command has a configuration entry with an upper case version of
+the command name. Options to commands start with the command
+name followed by an underscore and the option name. Global options are attached
+to the "toybox" command, and thus use the prefix "TOYBOX_". This organization
+is used by scripts/cfg2files to select which toys/*/*.c files to compile for a
+given .config.</p>
+</li>
+
+<li><p><b>generated/config.h</b> - list of CFG_SYMBOL and USE_SYMBOL() macros,
+generated from .config by a sed invocation in scripts/make.sh.</p>
+
+<p>CFG_SYMBOL is a comple time constant set to 1 for enabled symbols and 0 for
+disabled symbols. This allows the use of normal if() statements to remove
+code at compile time via the optimizer's dead code elimination (which removes
+from the binary any code that cannot be reached). This saves space without
+cluttering the code with #ifdefs or leading to configuration dependent build
+breaks. (See the 1992 Usenix paper
+<a href=http://doc.cat-v.org/henry_spencer/ifdef_considered_harmful.pdf>#ifdef
+Considered Harmful</a> for more information.)</p>
+
+<p>When you can't entirely avoid an #ifdef, the USE_SYMBOL(code) macro
+provides a less intrusive alternative, evaluating to the code in parentheses
+when the symbol is enabled, and nothing when the symbol is disabled. This
+is most commonly used around NEWTOY() declarations (so only the enabled
+commands show up in toy_list), and in option strings. This can also be used
+for things like varargs or structure members which can't always be
+eliminated by a simple test on CFG_SYMBOL. Remember, unlike CFG_SYMBOL
+this is really just a variant of #ifdef, and can still result in configuration
+dependent build breaks. Use with caution.</p>
+</li>
+
+<li><p><b>generated/flags.h</b> - FLAG_? macros indicating which command
+line options were seen. The option parsing in lib/args.c sets bits in
+toys.optflags, which can be tested by anding with the appropriate FLAG_
+macro. (Bare longopts, which have no corresponding short option, will
+have the longopt name after FLAG_. All others use the single letter short
+option.)</p>
+
+<p>To get the appropriate macros for your command, #define FOR_commandname
+before #including toys.h. To switch macro sets (because you have an OLDTOY()
+with different options in the same .c file), #define CLEANUP_oldcommand
+and also #define FOR_newcommand, then #include "generated/flags.h" to switch.
+</p>
+</li>
+
+<li><p><b>generated/globals.h</b> -
+Declares structures to hold the contents of each command's GLOBALS(),
+and combines them into "global_union this". (Yes, the name was
+chosen to piss off C++ developers who think that C
+is merely a subset of C++, not a language in its own right.)</p>
+
+<p>The union reuses the same memory for each command's global struct:
+since only one command's globals are in use at any given time, collapsing
+them together saves space. The headers #define TT to the appropriate
+"this.commandname", so you can refer to the current command's global
+variables out of "this" as TT.variablename.</p>
+
+<p>The globals start zeroed, and the first few are filled out by the
+lib/args.c argument parsing code called from main.c.</p>
+</li>
+
+<li><p><b>toys/help.h</b> - Help strings for use by the "help" command and
+--help options. This file #defines a help_symbolname string for each
+symbolname, but only the symbolnames matching command names get used
+by show_help() in lib/help.c to display help for commands.</p>
+
+<p>This file is created by scripts/make.sh, which compiles scripts/config2help.c
+into the binary generated/config2help, and then runs it against the top
+level .config and Config.in files to extract the help text from each config
+entry and collate together dependent options.</p>
+
+<p>This file contains help text for all commands, regardless of current
+configuration, but only the ones currently enabled in the .config file
+wind up in the help_data[] array, and only the enabled dependent options
+have their help text added to the command they depend on.</p>
+</li>
+
+<li><p><b>generated/newtoys.h</b> -
+All the NEWTOY() and OLDTOY() macros from toys/*/*.c. The "toybox" multiplexer
+is the first entry, the rest are in alphabetical order. Each line should be
+inside an appropriate USE_ macro, so code that #includes this file only sees
+the currently enabled commands.</p>
+
+<p>By #definining NEWTOY() to various things before #including this file,
+it may be used to create function prototypes (in toys.h), initialize the
+help_data array (in lib/help.c), initialize the toy_list array (in main.c,
+the alphabetical order lets toy_find() do a binary search, the exception to
+the alphabetical order lets it use the multiplexer without searching), and so
+on. (It's even used to initialize the NEED_OPTIONS macro, which produces a 1
+or 0 for each command using command line option parsing, which is ORed together
+to allow compile-time dead code elimination to remove the whole of
+lib/args.c if nothing currently enabled is using it.)<p>
+
+<p>Each NEWTOY and OLDTOY macro contains the command name, command line
+option string (telling lib/args.c how to parse command line options for
+this command), recommended install location, and miscelaneous data such
+as whether this command should retain root permissions if installed suid.</p>
+</li>
+
+<li><p><b>toys/oldtoys.h</b> - Macros with the command line option parsing

+<h3>lib/portability.h</h3>
+
+<p>This file is automatically included from the top of toys.h, and smooths
+over differences between platforms (hardware targets, compilers, C libraries,
+operating systems, etc).</p>
+
+<p>This file provides SWAP macros (SWAP_BE16(x) and SWAP_LE32(x) and so on).</p>
+
+<p>A macro like SWAP_LE32(x) means "The value in x is stored as a little
+endian 32 bit value, so perform the translation to/from whatever the native
+32-bit format is". You do the swap once on the way in, and once on the way
+out. If your target is already little endian, the macro is a NOP.</p>
+
+<p>The SWAP macros come in BE and LE each with 16, 32, and 64 bit versions.
+In each case, the name of the macro refers to the _external_ representation,
+and converts to/from whatever your native representation happens to be (which
+can vary depending on what you're currently compiling for).</p>
+
+<a name="lib_llist"><h3>lib/llist.c</h3>
+
+<p>Some generic single and doubly linked list functions, which take
+advantage of a couple properties of C:</p>
+
+<ul>
+<li><p>Structure elements are laid out in memory in the order listed, and
+the first element has no padding. This means you can always treat (typecast)
+a pointer to a structure as a pointer to the first element of the structure,
+even if you don't know anything about the data following it.</p></li>
+
+<li><p>An array of length zero at the end of a structure adds no space
+to the sizeof() the structure, but if you calculate how much extra space
+you want when you malloc() the structure it will be available at the end.
+Since C has no bounds checking, this means each struct can have one variable
+length array.</p></li>
+</ul>
+
+<p>Toybox's list structures always have their <b>next</b> pointer as
+the first entry of each struct, and singly linked lists end with a NULL pointer.
+This allows generic code to traverse such lists without knowing anything
+else about the specific structs composing them: if your pointer isn't NULL
+typecast it to void ** and dereference once to get the next entry.</p>
+
+<p><b>lib/lib.h</b> defines three structure types:</p>
+<ul>
+<li><p><b>struct string_list</b> - stores a single string (<b>char str[0]</b>),
+memory for which is allocated as part of the node. (I.E. llist_traverse(list,
+free); can clean up after this type of list.)</p></li>
+
+<li><p><b>struct arg_list</b> - stores a pointer to a single string
+(<b>char *arg</b>) which is stored in a separate chunk of memory.</p></li>
+
+<li><p><b>struct double_list</b> - has a second pointer (<b>struct double_list
+*prev</b> along with a <b>char *data</b> for payload.</p></li>
+</ul>
+
+<b>List Functions</b>
+
+<ul>
+<li><p>void *<b>llist_pop</b>(void **list) - advances through a list ala
+<b>node = llist_pop(&list);</b> This doesn't modify the list contents,
+but does advance the pointer you feed it (which is why you pass the _address_
+of that pointer, not the pointer itself).</p></li>
+
+<li><p>void <b>llist_traverse</b>(void *list, void (*using)(void *data)) -
+iterate through a list calling a function on each node.</p></li>
+
+<li><p>struct double_list *<b>dlist_add</b>(struct double_list **llist, char *data)
+- append an entry to a circular linked list.
+This function allocates a new struct double_list wrapper and returns the
+pointer to the new entry (which you can usually ignore since it's llist->prev,
+but if llist was NULL you need it). The argument is the ->data field for the
+new node.</p></li>
+<ul><li><p>void <b>dlist_add_nomalloc</b>(struct double_list **llist,
+struct double_list *new) - append existing struct double_list to
+list, does not allocate anything.</p></li></ul>
+</ul>
+
+<b>List code trivia questions:</b>
+
+<ul>
+<li><p><b>Why do arg_list and double_list contain a char * payload instead of
+a void *?</b> - Because you always have to typecast a void * to use it, and
+typecasting a char * does no harm. Since strings are the most common
+payload, and doing math on the pointer ala
+"(type *)(ptr+sizeof(thing)+sizeof(otherthing))" requires ptr to be char *
+anyway (at least according to the C standard), defaulting to char * saves
+a typecast.</p>
+</li>
+
+<li><p><b>Why do the names ->str, ->arg, and ->data differ?</b> - To force
+you to keep track of which one you're using, calling free(node->str) would
+be bad, and _failing_ to free(node->arg) leaks memory.</p></li>
+
+<li><p><b>Why does llist_pop() take a void * instead of void **?</b> -
+because the stupid compiler complains about "type punned pointers" when
+you typecast and dereference on the same line,
+due to insane FSF developers hardwiring limitations of their optimizer
+into gcc's warning system. Since C automatically typecasts any other
+pointer type to and from void *, the current code works fine. It's sad that it
+won't warn you if you forget the &, but the code crashes pretty quickly in
+that case.</p></li>
+
+<li><p><b>How do I assemble a singly-linked-list in order?</b> - use
+a double_list, dlist_add() your entries, and then break the circle with
+<b>list->prev->next = NULL;</b> when done.</li>
+</ul>
+
+<a name="lib_args"><h3>lib/args.c</h3>
+
+<p>Toybox's main.c automatically parses command line options before calling the
+command's main function. Option parsing starts in get_optflags(), which stores
+results in the global structures "toys" (optflags and optargs) and "this".</p>
+
+<p>The option parsing infrastructure stores a bitfield in toys.optflags to
+indicate which options the current command line contained, and defines FLAG
+macros code can use to check whether each argument's bit is set. Arguments
+attached to those options are saved into the command's global structure
+("this"). Any remaining command line arguments are collected together into
+the null-terminated array toys.optargs, with the length in toys.optc. (Note
+that toys.optargs does not contain the current command name at position zero,
+use "toys.which->name" for that.) The raw command line arguments get_optflags()
+parsed are retained unmodified in toys.argv[].</p>
+
+<p>Toybox's option parsing logic is controlled by an "optflags" string, using
+a format reminiscent of getopt's optargs but with several important differences.
+Toybox does not use the getopt()
+function out of the C library, get_optflags() is an independent implementation
+which doesn't permute the original arguments (and thus doesn't change how the
+command is displayed in ps and top), and has many features not present in
+libc optargs() (such as the ability to describe long options in the same string
+as normal options).</p>
+
+<p>Each command's NEWTOY() macro has an optflags string as its middle argument,
+which sets toy_list.options for that command to tell get_optflags() what
+command line arguments to look for, and what to do with them.
+If a command has no option
+definition string (I.E. the argument is NULL), option parsing is skipped
+for that command, which must look at the raw data in toys.argv to parse its
+own arguments. (If no currently enabled command uses option parsing,
+get_optflags() is optimized out of the resulting binary by the compiler's
+--gc-sections option.)</p>
+
+<p>You don't have to free the option strings, which point into the environment
+space (I.E. the string data is not copied). A TOYFLAG_NOFORK command
+that uses the linked list type "*" should free the list objects but not
+the data they point to, via "llist_free(TT.mylist, NULL);". (If it's not
+NOFORK, exit() will free all the malloced data anyway unless you want
+to implement a CONFIG_TOYBOX_FREE cleanup for it.)</p>
+
+<h4>Optflags format string</h4>
+
+<p>Note: the optflags option description string format is much more
+concisely described by a large comment at the top of lib/args.c.</p>
+
+<p>The general theory is that letters set optflags, and punctuation describes
+other actions the option parsing logic should take.</p>
+
+<p>For example, suppose the command line <b>command -b fruit -d walrus -a 42</b>
+is parsed using the optflags string "<b>a#b:c:d</b>". (I.E.
+toys.which->options="a#b:c:d" and argv = ["command", "-b", "fruit", "-d",
+"walrus", "-a", "42"]). When get_optflags() returns, the following data is
+available to command_main():
+
+<ul>
+<li><p>In <b>struct toys</b>:
+<ul>
+<li>toys.optflags = 13; // FLAG_a = 8 | FLAG_b = 4 | FLAG_d = 1</li>
+<li>toys.optargs[0] = "walrus"; // leftover argument</li>
+<li>toys.optargs[1] = NULL; // end of list</li>
+<li>toys.optc = 1; // there was 1 leftover argument</li>
+<li>toys.argv[] = {"-b", "fruit", "-d", "walrus", "-a", "42"}; // The original command line arguments
+</ul>
+<p></li>
+
+<li><p>In <b>union this</b> (treated as <b>long this[]</b>):
+<ul>
+<li>this[0] = NULL; // -c didn't get an argument this time, so get_optflags() didn't change it and toys_init() zeroed "this" during setup.)</li>
+<li>this[1] = (long)"fruit"; // argument to -b</li>
+<li>this[2] = 42; // argument to -a</li>
+</ul>
+</p></li>
+</ul>
+
+<p>If the command's globals are:</p>
+
+<blockquote><pre>
+GLOBALS(
+ char *c;
+ char *b;
+ long a;
+)
+</pre></blockquote>
+
+<p>That would mean TT.c == NULL, TT.b == "fruit", and TT.a == 42. (Remember,
+each entry that receives an argument must be a long or pointer, to line up
+with the array position. Right to left in the optflags string corresponds to
+top to bottom in GLOBALS().</p>
+
+<p>Put globals not filled out by the option parsing logic at the end of the
+GLOBALS block. Common practice is to list the options one per line (to
+make the ordering explicit, first to last in globals corresponds to right
+to left in the option string), then leave a blank line before any non-option
+globals.</p>
+
+<p><b>long toys.optflags</b></p>
+
+<p>Each option in the optflags string corresponds to a bit position in
+toys.optflags, with the same value as a corresponding binary digit. The
+rightmost argument is (1<<0), the next to last is (1<<1) and so on. If
+the option isn't encountered while parsing argv[], its bit remains 0.</p>
+
+<p>Each option -x has a FLAG_x macro for the command letter. Bare --longopts
+with no corresponding short option have a FLAG_longopt macro for the long
+optionname. Commands enable these macros by #defining FOR_commandname before
+#including <toys.h>. When multiple commands are implemented in the same
+source file, you can switch flag contexts later in the file by
+#defining CLEANUP_oldcommand and #defining FOR_newcommand, then
+#including <generated/flags.h>.</p>
+
+<p>Options disabled in the current configuration (wrapped in
+a USE_BLAH() macro for a CONFIG_BLAH that's switched off) have their
+corresponding FLAG macro set to zero, so code checking them ala
+if (toys.optargs & FLAG_x) gets optimized out via dead code elimination.
+#defining FORCE_FLAGS when switching flag context disables this
+behavior: the flag is never zero even if the config is disabled. This
+allows code shared between multiple commands to use the same flag
+values, as long as the common flags match up right to left in both option
+strings.</p>
+
+<p>For example,
+the optflags string "abcd" would parse the command line argument "-c" to set
+optflags to 2, "-a" would set optflags to 8, "-bd" would set optflags to
+6 (I.E. 4|2), and "-a -c" would set optflags to 10 (2|8). To check if -c
+was encountered, code could test: if (toys.optflags & FLAG_c) printf("yup");
+(See the toys/examples directory for more.)</p>
+
+<p>Only letters are relevant to optflags, punctuation is skipped: in the
+string "a*b:c#d", d=1, c=2, b=4, a=8. The punctuation after a letter
+usually indicate that the option takes an argument.</p>
+
+<p>Since toys.optflags is an unsigned int, it only stores 32 bits. (Which is
+the amount a long would have on 32-bit platforms anyway; 64 bit code on
+32 bit platforms is too expensive to require in common code used by almost
+all commands.) Bit positions beyond the 1<<31 aren't recorded, but
+parsing higher options can still set global variables.</p>
+
+<p><b>Automatically setting global variables from arguments (union this)</b></p>
+
+<p>The following punctuation characters may be appended to an optflags
+argument letter, indicating the option takes an additional argument:</p>
+
+<ul>
+<li><b>:</b> - plus a string argument, keep most recent if more than one.</li>
+<li><b>*</b> - plus a string argument, appended to a linked list.</li>
+<li><b>@</b> - plus an occurrence counter (stored in a long)</li>
+<li><b>#</b> - plus a signed long argument.
+<li><b>-</b> - plus a signed long argument defaulting to negative (start argument with + to force a positive value).</li>
+<li><b>.</b> - plus a floating point argument (if CFG_TOYBOX_FLOAT).</li>
+<ul>The following can be appended to a float or double:
+<li><b><123</b> - error if argument is less than this</li>
+<li><b>>123</b> - error if argument is greater than this</li>
+<li><b>=123</b> - default value if argument not supplied</li>
+</ul>
+</ul>
+
+<p><b>GLOBALS</b></p>
+
+<p>Options which have an argument fill in the corresponding slot in the global
+union "this" (see generated/globals.h), treating it as an array of longs
+with the rightmost saved in this[0]. As described above, using "a*b:c#d",
+"-c 42" would set this[0] = 42; and "-b 42" would set this[1] = "42"; each
+slot is left NULL if the corresponding argument is not encountered.</p>
+
+<p>This behavior is useful because the LP64 standard ensures long and pointer
+are the same size. C99 guarantees structure members will occur in memory
+in the same order they're declared, and that padding won't be inserted between
+consecutive variables of register size. Thus the first few entries can
+be longs or pointers corresponding to the saved arguments.</p>
+
+<p>See toys/example/*.c for longer examples of parsing options into the
+GLOBALS block.</p>
+
+<p><b>char *toys.optargs[]</b></p>
+
+<p>Command line arguments in argv[] which are not consumed by option parsing
+(I.E. not recognized either as -flags or arguments to -flags) will be copied
+to toys.optargs[], with the length of that array in toys.optc.
+(When toys.optc is 0, no unrecognized command line arguments remain.)
+The order of entries is preserved, and as with argv[] this new array is also
+terminated by a NULL entry.</p>
+
+<p>Option parsing can require a minimum or maximum number of optargs left
+over, by adding "<1" (read "at least one") or ">9" ("at most nine") to the
+start of the optflags string.</p>
+
+<p>The special argument "--" terminates option parsing, storing all remaining
+arguments in optargs. The "--" itself is consumed.</p>
+
+<p><b>Other optflags control characters</b></p>
+
+<p>The following characters may occur at the start of each command's
+optflags string, before any options that would set a bit in toys.optflags:</p>
+
+<ul>
+<li><b>^</b> - stop at first nonoption argument (for nice, xargs...)</li>
+<li><b>?</b> - allow unknown arguments (pass non-option arguments starting
+with - through to optargs instead of erroring out).</li>
+<li><b>&</b> - the first argument has imaginary dash (ala tar/ps. If given twice, all arguments have imaginary dash.)</li>
+<li><b><</b> - must be followed by a decimal digit indicating at least this many leftover arguments are needed in optargs (default 0)</li>
+<li><b>></b> - must be followed by a decimal digit indicating at most this many leftover arguments allowed (default MAX_INT)</li>
+</ul>
+
+<p>The following characters may be appended to an option character, but do
+not by themselves indicate an extra argument should be saved in this[].
+(Technically any character not recognized as a control character sets an
+optflag, but letters are never control characters.)</p>
+
+<ul>
+<li><b>^</b> - stop parsing options after encountering this option, everything else goes into optargs.</li>
+<li><b>|</b> - this option is required. If more than one marked, only one is required.</li>
+</ul>
+
+<p>The following may be appended to a float or double:</p>
+
+<ul>
+<li><b><123</b> - error if argument is less than this</li>
+<li><b>>123</b> - error if argument is greater than this</li>
+<li><b>=123</b> - default value if argument not supplied</li>
+</ul>
+
+<p>Option parsing only understands <>= after . when CFG_TOYBOX_FLOAT
+is enabled. (Otherwise the code to determine where floating point constants
+end drops out. When disabled, it can reserve a global data slot for the
+argument so offsets won't change, but will never fill it out.) You can handle
+this by using the USE_BLAH() macros with C string concatenation, ala:</p>
+
+<blockquote>"abc." USE_TOYBOX_FLOAT("<1.23>4.56=7.89") "def"</blockquote>
+
+<p><b>--longopts</b></p>
+
+<p>The optflags string can contain long options, which are enclosed in
+parentheses. They may be appended to an existing option character, in
+which case the --longopt is a synonym for that option, ala "a:(--fred)"
+which understands "-a blah" or "--fred blah" as synonyms.</p>
+
+<p>Longopts may also appear before any other options in the optflags string,
+in which case they have no corresponding short argument, but instead set
+their own bit based on position. So for "(walrus)#(blah)xy:z", "command
+--walrus 42" would set toys.optflags = 16 (-z = 1, -y = 2, -x = 4, --blah = 8)
+and would assign this[1] = 42;</p>
+
+<p>A short option may have multiple longopt synonyms, "a(one)(two)", but
+each "bare longopt" (ala "(one)(two)abc" before any option characters)
+always sets its own bit (although you can group them with +X).</p>
+
+<p>Only bare longopts have a FLAG_ macro with the longopt name
+(ala --fred would #define FLAG_fred). Other longopts use the short
+option's FLAG macro to test the toys.optflags bit.</p>
+
+<p>Options with a semicolon ";" after their data type can only set their
+corresponding GLOBALS() entry via "--longopt=value". For example, option
+string "x(boing): y" would set TT.x if it saw "--boing=value", but would
+treat "--boing value" as setting FLAG_x in toys.optargs, leaving TT.x NULL,
+and keeping "value" in toys.optargs[]. (This lets "ls --color" and
+"ls --color=auto" both work.)</p>
+
+<p><b>[groups]</b></p>
+
+<p>At the end of the option string, square bracket groups can define
+relationships between existing options. (This only applies to short
+options, bare --longopts can't participate.)</p>
+
+<p>The first character of the group defines the type, the remaining
+characters are options it applies to:</p>
+
+<ul>
+<li><b>-</b> - Exclusive, switch off all others in this group.</li>
+<li><b>+</b> - Inclusive, switch on all others in this group.</li>
+<li><b>!</b> - Error, fail if more than one defined.</li>
+</ul>
+
+<p>So "abc[-abc]" means -ab = -b, -ba = -a, -abc = -c. "abc[+abc]"
+means -ab=-abc, -c=-abc, and "abc[!abc] means -ab calls error_exit("no -b
+with -a"). Note that [-] groups clear the GLOBALS option slot of
+options they're switching back off, but [+] won't set options it didn't see
+(just the optflags).</p>
+
+<p><b>whitespace</b></p>
+
+<p>Arguments may occur with or without a space (I.E. "-a 42" or "-a42").
+The command line argument "-abc" may be interepreted many different ways:
+the optflags string "cba" sets toys.optflags = 7, "c:ba" sets toys.optflags=4
+and saves "ba" as the argument to -c, and "cb:a" sets optflags to 6 and saves
+"c" as the argument to -b.</p>
+
+<p>Note that & changes whitespace handling, so that the command line
+"tar cvfCj outfile.tar.bz2 topdir filename" is parsed the same as
+"tar filename -c -v -j -f outfile.tar.bz2 -C topdir". Note that "tar -cvfCj
+one two three" would equal "tar -c -v -f Cj one two three". (This matches
+historical usage.)</p>
+
+<p>Appending a space to the option in the option string ("a: b") makes it
+require a space, I.E. "-ab" is interpreted as "-a" "-b". That way "kill -stop"
+differs from "kill -s top".</p>
+
+<p>Appending ; to a longopt in the option string makes its argument optional,
+and only settable with =, so in ls "(color):;" can accept "ls --color" and
+"ls --color=auto" without complaining that the first has no argument.</p>
+
+<a name="lib_dirtree"><h3>lib/dirtree.c</h3>
+
+<p>The directory tree traversal code should be sufficiently generic
+that commands never need to use readdir(), scandir(), or the fts.h family
+of functions.</p>
+
+<p>These functions do not call chdir() or rely on PATH_MAX. Instead they
+use openat() and friends, using one filehandle per directory level to
+recurse into subdirectories. (I.E. they can descend 1000 directories deep
+if setrlimit(RLIMIT_NOFILE) allows enough open filehandles, and the default
+in /proc/self/limits is generally 1024.)</p>
+
+<p>There are two main ways to use dirtree: 1) assemble a tree of nodes
+representing a snapshot of directory state and traverse them using the
+->next and ->child pointers, or 2) traverse the tree calling a callback
+function on each entry, and freeing its node afterwards. (You can also
+combine the two, using the callback as a filter to determine which nodes
+to keep.)</p>
+
+<p>The basic dirtree functions are:</p>
+
+<ul>
+<li><p><b>struct dirtree *dirtree_read(char *path, int (*callback)(struct
+dirtree node))</b> - recursively read files and directories, calling
+callback() on each, and returning a tree of saved nodes (if any).
+If path doesn't exist, returns DIRTREE_ABORTVAL. If callback is NULL,
+returns a single node at that path.</p>
+
+<li><p><b>dirtree_notdotdot(struct dirtree *new)</b> - standard callback
+which discards "." and ".." entries and returns DIRTREE_SAVE|DIRTREE_RECURSE
+for everything else. Used directly, this assembles a snapshot tree of
+the contents of this directory and its subdirectories
+to be processed after dirtree_read() returns (by traversing the
+struct dirtree's ->next and ->child pointers from the returned root node).</p>
+
+<li><p><b>dirtree_path(struct dirtree *node, int *plen)</b> - malloc() a
+string containing the path from the root of this tree to this node. If
+plen isn't NULL then *plen is how many extra bytes to malloc at the end
+of string.</p></li>
+
+<li><p><b>dirtree_parentfd(struct dirtree *node)</b> - return fd of
+directory containing this node, for use with openat() and such.</p></li>
+</ul>
+
+<p>The <b>dirtree_read()</b> function is the standard way to start
+directory traversal. It takes two arguments: a starting path for
+the root of the tree, and a callback function. The callback() is called
+on each directory entry, its argument is a fully populated
+<b>struct dirtree *</b> (from lib/lib.h) describing the node, and its
+return value tells the dirtree infrastructure what to do next.</p>
+
+<p>(There's also a three argument version,
+<b>dirtree_flagread(char *path, int flags, int (*callback)(struct
+dirtree node))</b>, which lets you apply flags like DIRTREE_SYMFOLLOW and
+DIRTREE_SHUTUP to reading the top node, but this only affects the top node.
+Child nodes use the flags returned by callback().</p>
+
+<p><b>struct dirtree</b></p>
+
+<p>Each struct dirtree node contains <b>char name[]</b> and <b>struct stat
+st</b> entries describing a file, plus a <b>char *symlink</b>
+which is NULL for non-symlinks.</p>
+
+<p>During a callback function, the <b>int dirfd</b> field of directory nodes
+contains a directory file descriptor (for use with the openat() family of
+functions). This isn't usually used directly, intstead call dirtree_parentfd()
+on the callback's node argument. The <b>char again</a> field is 0 for the
+first callback on a node, and 1 on the second callback (triggered by returning
+DIRTREE_COMEAGAIN on a directory, made after all children have been processed).
+</p>
+
+<p>Users of this code may put anything they like into the <b>long extra</b>
+field. For example, "cp" and "mv" use this to store a dirfd for the destination
+directory (and use DIRTREE_COMEAGAIN to get the second callback so they can
+close(node->extra) to avoid running out of filehandles).
+This field is not directly used by the dirtree code, and
+thanks to LP64 it's large enough to store a typecast pointer to an
+arbitrary struct.</p>
+
+<p>The return value of the callback combines flags (with boolean or) to tell
+the traversal infrastructure how to behave:</p>
+
+<ul>
+<li><p><b>DIRTREE_SAVE</b> - Save this node, assembling a tree. (Without
+this the struct dirtree is freed after the callback returns. Filtering out
+siblings is fine, but discarding a parent while keeping its child leaks
+memory.)</p></li>
+<li><p><b>DIRTREE_ABORT</b> - Do not examine any more entries in this
+directory. (Does not propagate up tree: to abort entire traversal,
+return DIRTREE_ABORT from parent callbacks too.)</p></li>
+<li><p><b>DIRTREE_RECURSE</b> - Examine directory contents. Ignored for
+non-directory entries. The remaining flags only take effect when
+recursing into the children of a directory.</p></li>
+<li><p><b>DIRTREE_COMEAGAIN</b> - Call the callback on this node a second time
+after examining all directory contents, allowing depth-first traversal.
+On the second call, dirtree->again is nonzero.</p></li>
+<li><p><b>DIRTREE_SYMFOLLOW</b> - follow symlinks when populating children's
+<b>struct stat st</b> (by feeding a nonzero value to the symfollow argument of
+dirtree_add_node()), which means DIRTREE_RECURSE treats symlinks to
+directories as directories. (Avoiding infinite recursion is the callback's
+problem: the non-NULL dirtree->symlink can still distinguish between
+them. The "find" command follows ->parent up the tree to the root node
+each time, checking to make sure that stat's dev and inode pair don't
+match any ancestors.)</p></li>
+</ul>
+
+<p>Each struct dirtree contains three pointers (next, parent, and child)
+to other struct dirtree.</p>
+
+<p>The <b>parent</b> pointer indicates the directory
+containing this entry; even when not assembling a persistent tree of
+nodes the parent entries remain live up to the root of the tree while
+child nodes are active. At the top of the tree the parent pointer is
+NULL, meaning the node's name[] is either an absolute path or relative
+to cwd. The function dirtree_parentfd() gets the directory file descriptor
+for use with openat() and friends, returning AT_FDCWD at the top of tree.</p>
+
+<p>The <b>child</b> pointer points to the first node of the list of contents of
+this directory. If the directory contains no files, or the entry isn't
+a directory, child is NULL.</p>
+
+<p>The <b>next</b> pointer indicates sibling nodes in the same directory as this
+node, and since it's the first entry in the struct the llist.c traversal
+mechanisms work to iterate over sibling nodes. Each dirtree node is a
+single malloc() (even char *symlink points to memory at the end of the node),
+so llist_free() works but its callback must descend into child nodes (freeing
+a tree, not just a linked list), plus whatever the user stored in extra.</p>
+
+<p>The <b>dirtree_flagread</b>() function is a simple wrapper, calling <b>dirtree_add_node</b>()
+to create a root node relative to the current directory, then calling
+<b>dirtree_handle_callback</b>() on that node (which recurses as instructed by the callback
+return flags). The flags argument primarily lets you
+control whether or not to follow symlinks to the root node; symlinks
+listed on the command line are often treated differently than symlinks
+encountered during recursive directory traversal.
+
+<p>The ls command not only bypasses this wrapper, but never returns
+<b>DIRTREE_RECURSE</b> from the callback, instead calling <b>dirtree_recurse</b>() manually
+from elsewhere in the program. This gives ls -lR manual control
+of traversal order, which is neither depth first nor breadth first but
+instead a sort of FIFO order requried by the ls standard.</p>

+<html><head><title>The design of toybox</title></head>
+<!--#include file="header.html" -->
+
+<b><h2>Design goals</h2></b>
+
+<p>Toybox should be simple, small, fast, and full featured. Often, these
+things need to be balanced off against each other. In general, keeping the
+code simple the most important (and hardest) goal, and small is slightly more
+important than fast. Features are the reason we write code in the first
+place but this has all been implemented before so if we can't do a better
+job why bother? It should be possible to get 80% of the way to each goal
+before they really start to fight.</p>
+
+<p>Here they are in reverse order of importance:</p>
+
+<b><h3>Features</h3></b>
+
+<p>The <a href=roadmap.html>roadmap</a> has the list of features we're
+trying to implement, and the reasons for them. After the 1.0 release
+some of that material may get moved here.</p>
+
+<p>Some things are simply outside the scope of the project: even though
+posix defines commands for compiling and linking, we're not going to include
+a compiler or linker (and support for a potentially infinite number of hardware
+targets). And until somebody comes up with a ~30k ssh implementation, we're
+going to point you at dropbear or polarssl.</p>
+
+<p>Environmental dependencies are a type of complexity, so needing other
+packages to build or run is a big downside. For example, we don't use curses
+when we can simply output ansi escape sequences and trust all terminal
+programs written in the past 30 years to be able to support them. (A common
+use case is to download a statically linked toybox binary to an arbitrary
+Linux system, and use it in an otherwise unknown environment; being
+self-contained helps support this.)</p>
+
+<b><h3>Speed</h3></b>
+
+<p>It's easy to say lots about optimizing for speed (which is why this section
+is so long), but at the same time it's the optimization we care the least about.
+The essence of speed is being as efficient as possible, which means doing as
+little work as possible. A design that's small and simple gets you 90% of the
+way there, and most of the rest is either fine-tuning or more trouble than
+it's worth (and often actually counterproductive). Still, here's some
+advice:</p>
+
+<p>First, understand the darn problem you're trying to solve. You'd think
+I wouldn't have to say this, but I do. Trying to find a faster sorting
+algorithm is no substitute for figuring out a way to skip the sorting step
+entirely. The fastest way to do anything is not to have to do it at all,
+and _all_ optimization boils down to avoiding unnecessary work.</p>
+
+<p>Speed is easy to measure; there are dozens of profiling tools for Linux
+(although personally I find the "time" command a good starting place).
+Don't waste too much time trying to optimize something you can't measure,
+and there's no much point speeding up things you don't spend much time doing
+anyway.</p>
+
+<p>Understand the difference between throughput and latency. Faster
+processors improve throughput, but don't always do much for latency.
+After 30 years of Moore's Law, most of the remaining problems are latency,
+not throughput. (There are of course a few exceptions, like data compression
+code, encryption, rsync...) Worry about throughput inside long-running
+loops, and worry about latency everywhere else. (And don't worry too much
+about avoiding system calls or function calls or anything else in the name
+of speed unless you are in the middle of a tight loop that's you've already
+proven isn't running fast enough.)</p>
+
+<p>"Locality of reference" is generally nice, in all sorts of contexts.
+It's obvious that waiting for disk access is 1000x slower than doing stuff in
+RAM (and making the disk seek is 10x slower than sequential reads/writes),
+but it's just as true that a loop which stays in L1 cache is many times faster
+than a loop that has to wait for a DRAM fetch on each iteration. Don't worry
+about whether "&" is faster than "%" until your executable loop stays in L1
+cache and the data access is fetching cache lines intelligently. (To
+understand DRAM, L1, and L2 cache, read Hannibal's marvelous ram guide at Ars
+Technica:
+<a href=http://arstechnica.com/paedia/r/ram_guide/ram_guide.part1-2.html>part one</a>,
+<a href=http://arstechnica.com/paedia/r/ram_guide/ram_guide.part2-1.html>part two</a>,
+<a href=http://arstechnica.com/paedia/r/ram_guide/ram_guide.part3-1.html>part three</a>,
+plus this
+<a href=http://arstechnica.com/articles/paedia/cpu/caching.ars/1>article on
+cacheing</a>, and this one on
+<a href=http://arstechnica.com/articles/paedia/cpu/bandwidth-latency.ars>bandwidth
+and latency</a>.
+And there's <a href=http://arstechnica.com/paedia/index.html>more where that came from</a>.)
+Running out of L1 cache can execute one instruction per clock cycle, going
+to L2 cache costs a dozen or so clock cycles, and waiting for a worst case dram
+fetch (round trip latency with a bank switch) can cost thousands of
+clock cycles. (Historically, this disparity has gotten worse with time,
+just like the speed hit for swapping to disk. These days, a _big_ L1 cache
+is 128k and a big L2 cache is a couple of megabytes. A cheap low-power
+embedded processor may have 8k of L1 cache and no L2.)</p>
+
+<p>Learn how <a href=http://nommu.org/memory-faq.txt>virtual memory and
+memory managment units work</a>. Don't touch
+memory you don't have to. Even just reading memory evicts stuff from L1 and L2
+cache, which may have to be read back in later. Writing memory can force the
+operating system to break copy-on-write, which allocates more memory. (The
+memory returned by malloc() is only a virtual allocation, filled with lots of
+copy-on-write mappings of the zero page. Actual physical pages get allocated
+when the copy-on-write gets broken by writing to the virtual page. This
+is why checking the return value of malloc() isn't very useful anymore, it
+only detects running out of virtual memory, not physical memory. Unless
+you're using a <a href=http://nommu.org>NOMMU system</a>, where all bets are off.)</p>
+
+<p>Don't think that just because you don't have a swap file the system can't
+start swap thrashing: any file backed page (ala mmap) can be evicted, and
+there's a reason all running programs require an executable file (they're
+mmaped, and can be flushed back to disk when memory is short). And long
+before that, disk cache gets reclaimed and has to be read back in. When the
+operating system really can't free up any more pages it triggers the out of
+memory killer to free up pages by killing processes (the alternative is the
+entire OS freezing solid). Modern operating systems seldom run out of
+memory gracefully.</p>
+
+<p>Also, it's better to be simple than clever. Many people think that mmap()
+is faster than read() because it avoids a copy, but twiddling with the memory
+management is itself slow, and can cause unnecessary CPU cache flushes. And
+if a read faults in dozens of pages sequentially, but your mmap iterates
+backwards through a file (causing lots of seeks, each of which your program
+blocks waiting for), the read can be many times faster. On the other hand, the
+mmap can sometimes use less memory, since the memory provided by mmap
+comes from the page cache (allocated anyway), and it can be faster if you're
+doing a lot of different updates to the same area. The moral? Measure, then
+try to speed things up, and measure again to confirm it actually _did_ speed
+things up rather than made them worse. (And understanding what's really going
+on underneath is a big help to making it happen faster.)</p>
+
+<p>In general, being simple is better than being clever. Optimization
+strategies change with time. For example, decades ago precalculating a table
+of results (for things like isdigit() or cosine(int degrees)) was clearly
+faster because processors were so slow. Then processors got faster and grew
+math coprocessors, and calculating the value each time became faster than
+the table lookup (because the calculation fit in L1 cache but the lookup
+had to go out to DRAM). Then cache sizes got bigger (the Pentium M has
+2 megabytes of L2 cache) and the table fit in cache, so the table became
+fast again... Predicting how changes in hardware will affect your algorithm
+is difficult, and using ten year old optimization advice and produce
+laughably bad results. But being simple and efficient is always going to
+give at least a reasonable result.</p>
+
+<p>The famous quote from Ken Thompson, "When in doubt, use brute force",
+applies to toybox. Do the simple thing first, do as little of it as possible,
+and make sure it's right. You can always speed it up later.</p>
+
+<b><h3>Size</h3></b>
+<p>Again, simple gives you most of this. An algorithm that does less work
+is generally smaller. Understand the problem, treat size as a cost, and
+get a good bang for the byte.</p>
+
+<p>Understand the difference between binary size, heap size, and stack size.
+Your binary is the executable file on disk, your heap is where malloc() memory
+lives, and your stack is where local variables (and function call return
+addresses) live. Optimizing for binary size is generally good: executing
+fewer instructions makes your program run faster (and fits more of it in
+cache). On embedded systems, binary size is especially precious because
+flash is expensive (and its successor, MRAM, even more so). Small stack size
+is important for nommu systems because they have to preallocate their stack
+and can't make it bigger via page fault. And everybody likes a small heap.</p>
+
+<p>Measure the right things. Especially with modern optimizers, expecting
+something to be smaller is no guarantee it will be after the compiler's done
+with it. Binary size isn't the most accurate indicator of the impact of a
+given change, because lots of things get combined and rounded during
+compilation and linking. Matt Mackall's bloat-o-meter is a python script
+which compares two versions of a program, and shows size changes in each
+symbol (using the "nm" command behind the scenes). To use this, run
+"make baseline" to build a baseline version to compare against, and
+then "make bloatometer" to compare that baseline version against the current
+code.</p>
+
+<p>Avoid special cases. Whenever you see similar chunks of code in more than
+one place, it might be possible to combine them and have the users call shared
+code. (This is the most commonly cited trick, which doesn't make it easy. If
+seeing two lines of code do the same thing makes you slightly uncomfortable,
+you've got the right mindset.)</p>
+
+<p>Some specific advice: Using a char in place of an int when doing math
+produces significantly larger code on some platforms (notably arm),
+because each time the compiler has to emit code to convert it to int, do the
+math, and convert it back. Bitfields have this problem on most platforms.
+Because of this, using char to index a for() loop is probably not a net win,
+although using char (or a bitfield) to store a value in a structure that's
+repeated hundreds of times can be a good tradeoff of binary size for heap
+space.</p>
+
+<b><h3>Simple</h3></b>
+
+<p>Complexity is a cost, just like code size or runtime speed. Treat it as
+a cost, and spend your complexity budget wisely. (Sometimes this means you
+can't afford a feature because it complicates the code too much to be
+worth it.)</p>
+
+<p>Simplicity has lots of benefits. Simple code is easy to maintain, easy to
+port to new processors, easy to audit for security holes, and easy to
+understand.</p>
+
+<p>Simplicity itself can have subtle non-obvious aspects requiring a tradeoff
+between one kind of simplicity and another: simple for the computer to
+execute and simple for a human reader to understand aren't always the
+same thing. A compact and clever algorithm that does very little work may
+not be as easy to explain or understand as a larger more explicit version
+requiring more code, memory, and CPU time. When balancing these, err on the
+side of doing less work, but add comments describing how you
+could be more explicit.</p>
+
+<p>In general, comments are not a substitute for good code (or well chosen
+variable or function names). Commenting "x += y;" with "/* add y to x */"
+can actually detract from the program's readability. If you need to describe
+what the code is doing (rather than _why_ it's doing it), that means the
+code itself isn't very clear.</p>
+
+<p>Prioritizing simplicity tends to serve our other goals: simplifying code
+generally reduces its size (both in terms of binary size and runtime memory
+usage), and avoiding unnecessary work makes code run faster. Smaller code
+also tends to run faster on modern hardware due to CPU cacheing: fitting your
+code into L1 cache is great, and staying in L2 cache is still pretty good.</p>
+
+<p>But a simple implementation is not always the smallest or fastest, and
+balancing simplicity vs the other goals can be difficult. For example, the
+atolx_range() function in lib/lib.c uses the always 64 bit "long long" type,
+which produces larger and slower code on 32 bit platforms and
+often assigned into smaller interger types. Although libc has parallel
+implementations for different data sizes (atoi, atol, atoll) we only
+used the largest, which can cover all cases.</p>
+
+<p>On the other hand, the "tail" command has two codepaths, one for seekable
+files and one for nonseekable files. Although the nonseekable case can handle
+all inputs (and is required when input comes from a pipe or similar, so cannot
+be removed), reading through multiple gigabytes of data to reach the end of
+seekable files was both a common case and hugely penalized by a nonseekable
+approach (half-minute wait vs instant results). This is one example
+where performance did outweigh simplicity of implementation.</p>
+
+<p><a href=http://www.joelonsoftware.com/articles/fog0000000069.html>Joel
+Spolsky argues against throwing code out and starting over</a>, and he has
+good points: an existing debugged codebase contains a huge amount of baked
+in knowledge about strange real-world use cases that the designers didn't
+know about until users hit the bugs, and most of this knowledge is never
+explicitly stated anywhere except in the source code.</p>
+
+<p>That said, the Mythical Man-Month's "build one to throw away" advice points
+out that until you've solved the problem you don't properly understand it, and
+about the time you finish your first version is when you've finally figured
+out what you _should_ have done. (The corrolary is that if you build one
+expecting to throw it away, you'll actually wind up throwing away two. You
+don't understand the problem until you _have_ solved it.)</p>
+
+<p>Joel is talking about what closed source software can afford to do: Code
+that works and has been paid for is a corporate asset not lightly abandoned.
+Open source software can afford to re-implement code that works, over and
+over from scratch, for incremental gains. Before toybox, the unix command line
+has already been reimplemented from scratch several times (the
+original AT&T Unix command line in assembly and then in C, the BSD
+versions, Coherent was the first full from-scratch Unix clone in 1980,
+Minix was another clone which Linux was inspired by and developed under,
+the GNU tools were yet another rewrite intended for use in the stillborn
+"Hurd" project, BusyBox was still another rewrite, and more versions
+were written in Plan 9, uclinux, klibc, sash, sbase, s6, and of course
+android toolbox...) but maybe toybox can do a better job. :)</p>
+
+<p>As Antoine de St. Exupery (author of "The Little Prince" and an early
+aircraft designer) said, "Perfection is achieved, not when there
+is nothing left to add, but when there is nothing left to take away."
+And Ken Thompson (creator of Unix) said "One of my most productive
+days was throwing away 1000 lines of code." It's always possible to
+come up with a better way to do it.</p>
+
+<p>P.S. How could I resist linking to an article about
+<a href=http://blog.outer-court.com/archive/2005-08-24-n14.html>why
+programmers should strive to be lazy and dumb</a>?</p>
+
+<b><h2>Portability issues</h2></b>
+
+<b><h3>Platforms</h3></b>
+<p>Toybox should run on Android (all commands with musl-libc, as large a subset
+as practical with bionic), and every other hardware platform Linux runs on.
+Other posix/susv4 environments (perhaps MacOS X or newlib+libgloss) are vaguely
+interesting but only if they're easy to support; I'm not going to spend much
+effort on them.</p>
+
+<p>I don't do windows.</p>
+
+<p>We depend on C99 and posix-2008 libc features such as the openat() family of
+functions. We also assume certain "modern" linux kernel behavior such
+as large environment sizes (linux commit b6a2fea39318, went into 2.6.22
+released July 2007). In theory this shouldn't prevent us from working on
+older kernels or other implementations (ala BSD), but we don't police their
+corner cases.</p>
+
+<b><h3>32/64 bit</h3></b>
+<p>Toybox should work on both 32 bit and 64 bit systems. 64 bit desktop
+hardware went mainstream in 2005 and was essentially ubiquitous
+by the end of the decade, but 32 bit hardware will continue to be important
+in embedded devices for several more years.</p>
+
+<p>Toybox relies on the fact that on any Unix-like platform, pointer and long
+are always the same size (on both 32 and 64 bit). Pointer and int are _not_
+the same size on 64 bit systems, but pointer and long are.</p>
+
+<p>This is guaranteed by the LP64 memory model, a Unix standard (which Linux
+and MacOS X both implement, and which modern 64 bit processors such as
+x86-64 were <a href=http://www.pagetable.com/?p=6>designed for</a>). See
+<a href=http://www.unix.org/whitepapers/64bit.html>the LP64 standard</a> and
+<a href=http://www.unix.org/version2/whatsnew/lp64_wp.html>the LP64
+rationale</a> for details.</p>
+
+<p>Note that Windows doesn't work like this, and I don't care.
+<a href=http://blogs.msdn.com/oldnewthing/archive/2005/01/31/363790.aspx>The
+insane legacy reasons why this is broken on Windows are explained here.</a></p>
+
+<b><h3>Signedness of char</h3></b>
+<p>On platforms like x86, variables of type char default to unsigned. On
+platforms like arm, char defaults to signed. This difference can lead to
+subtle portability bugs, and to avoid them we specify which one we want by
+feeding the compiler -funsigned-char.</p>
+
+<p>The reason to pick "unsigned" is that way we're 8-bit clean by default.</p>
+
+<p><h3>Error messages and internationalization:</h3></p>
+
+<p>Error messages are extremely terse not just to save bytes, but because we
+don't use any sort of _("string") translation infrastructure. (We're not
+translating the command names themselves, so we must expect a minimum amount of
+english knowledge from our users, but let's keep it to a minimum.)</p>
+
+<p>Thus "bad -A '%c'" is
+preferable to "Unrecognized address base '%c'", because a non-english speaker
+can see that -A was the problem (giving back the command line argument they
+supplied). A user with a ~20 word english vocabulary is
+more likely to know (or guess) "bad" than the longer message, and you can
+use "bad" in place of "invalid", "inappropriate", "unrecognized"...
+Similarly when atolx_range() complains about range constraints with
+"4 < 17" or "12 > 5", it's intentional: those don't need to be translated.</p>
+
+<p>The strerror() messages produced by perror_exit() and friends should be
+localized by libc, and our error functions also prepend the command name
+(which non-english speakers can presumably recognize already). Keep the
+explanation in between to a minimum, and where possible feed back the values
+they passed in to identify _what_ we couldn't process.
+If you say perror_exit("setsockopt"), you've identified the action you
+were trying to take, and the perror gives a translated error message (from libc)
+explaining _why_ it couldn't do it, so you probably don't need to add english
+words like "failed" or "couldn't assign".</p>
+
+<p>All commands should be 8-bit clean, with explicit
+<a href=http://yarchive.net/comp/linux/utf8.html>UTF-8</a> support where
+necessary. Assume all input data might be utf8, and at least preserve
+it and pass it through. (For this reason, our build is -funsigned-char on
+all architectures; "char" is unsigned unless you stick "signed" in front
+of it.)</p>
+
+<p>Locale support isn't currently a goal; that's a presentation layer issue
+(I.E. a GUI problem).</p>
+
+<p><h3>Shared Libraries</h3></p>
+
+<p>Toybox's policy on shared libraries is that they should never be
+required, but can optionally be used to improve performance.</p>
+
+<p>Toybox should provide the command line utilities for
+<a href=roadmap.html#dev_env>self-hosting development evirionments</a>,
+and an easy way to set up "hermetic builds" (I.E. builds which provide
+their own dependencies, isolating the build logic from host command version
+skew with a simple known build environment). In both cases, external
+dependencies defeat the purpose.</p>
+
+<p>This means toybox should provide full functionality without relying
+on any external dependencies (other than libc). But toybox may optionally use
+libraries such as zlib and openssl to improve performance for things like
+deflate and sha1sum, which lets the corresponding built-in implementations
+be simple (and thus slow). But the built-in implementations need to exist and
+work.</p>
+
+<p>(This is why we use an external https wrapper program, because depending on
+openssl or similar to be linked in would change the behavior of toybox.)</p>
+
+<a name="codestyle" />
+<h2>Coding style</h2>
+
+<p>The real coding style holy wars are over things that don't matter
+(whitespace, indentation, curly bracket placement...) and thus have no
+obviously correct answer. As in academia, "the fighting is so vicious because
+the stakes are so small". That said, being consistent makes the code readable,
+so here's how to make toybox code look like other toybox code.</p>
+
+<p>Toybox source uses two spaces per indentation level, and wraps at 80
+columns. (Indentation of continuation lines is awkward no matter what
+you do, sometimes two spaces looks better, sometimes indenting to the
+contents of a parentheses looks better.)</p>
+
+<p>I'm aware this indentation style creeps some people out, so here's
+the sed invocation to convert groups of two leading spaces to tabs:</p>
+<blockquote><pre>
+sed -i ':loop;s/^\( *\) /\1\t/;t loop' filename
+</pre></blockquote>
+
+<p>And here's the sed invocation to convert leading tabs to two spaces each:</p>
+<blockquote><pre>
+sed -i ':loop;s/^\( *\)\t/\1 /;t loop' filename
+</pre></blockquote>
+
+<p>There's a space after C flow control statements that look like functions, so
+"if (blah)" instead of "if(blah)". (Note that sizeof is actually an
+operator, so we don't give it a space for the same reason ++ doesn't get
+one. Yeah, it doesn't need the parentheses either, but it gets them.
+These rules are mostly to make the code look consistent, and thus easier
+to read.) We also put a space around assignment operators (on both sides),
+so "int x = 0;".</p>
+
+<p>Blank lines (vertical whitespace) go between thoughts. "We were doing that,
+now we're doing this." (Not a hard and fast rule about _where_ it goes,
+but there should be some for the same reason writing has paragraph breaks.)</p>
+
+<p>Variable declarations go at the start of blocks, with a blank line between
+them and other code. Yes, c99 allows you to put them anywhere, but they're
+harder to find if you do that. If there's a large enough distance between
+the declaration and the code using it to make you uncomfortable, maybe the
+function's too big, or is there an if statement or something you can
+use as an excuse to start a new closer block?</p>
+
+<p>If statments with a single line body go on the same line if the result
+fits in 80 columns, on a second line if it doesn't. We usually only use
+curly brackets if we need to, either because the body is multiple lines or
+because we need to distinguish which if an else binds to. Curly brackets go
+on the same line as the test/loop statement. The exception to both cases is
+if the test part of an if statement is long enough to split into multiple
+lines, then we put the curly bracket on its own line afterwards (so it doesn't
+get lost in the multple line variably indented mess), and we put it there
+even if it's only grouping one line (because the indentation level is not
+providing clear information in that case).</p>
+
+<p>I.E.</p>
+
+<blockquote>
+<pre>
+if (thingy) thingy;
+else thingy;
+
+if (thingy) {
+ thingy;
+ thingy;
+} else thingy;
+
+if (blah blah blah...
+ && blah blah blah)
+{
+ thingy;
+}
+</pre></blockquote>
+
+<p>Gotos are allowed for error handling, and for breaking out of
+nested loops. In general, a goto should only jump forward (not back), and
+should either jump to the end of an outer loop, or to error handling code
+at the end of the function. Goto labels are never indented: they override the
+block structure of the file. Putting them at the left edge makes them easy
+to spot as overrides to the normal flow of control, which they are.</p>
+
+<p>When there's a shorter way to say something, we tend to do that for
+consistency. For example, we tend to say "*blah" instead of "blah[0]" unless
+we're referring to more than one element of blah. Similarly, NULL is
+really just 0 (and C will automatically typecast 0 to anything, except in
+varargs), "if (function() != NULL)" is the same as "if (function())",
+"x = (blah == NULL);" is "x = !blah;", and so on.</p>
+
+<p>The goal is to be
+concise, not cryptic: if you're worried about the code being hard to
+understand, splitting it to multiple steps on multiple lines is
+better than a NOP operation like "!= NULL". A common sign of trying to
+hard is nesting ? : three levels deep, sometimes if/else and a temporary
+variable is just plain easier to read. If you think you need a comment,
+you may be right.</p>
+
+<p>Comments are nice, but don't overdo it. Comments should explain _why_,
+not how. If the code doesn't make the how part obvious, that's a problem with
+the code. Sometimes choosing a better variable name is more revealing than a
+comment. Comments on their own line are better than comments on the end of
+lines, and they usually have a blank line before them. Most of toybox's
+comments are c99 style // single line comments, even when there's more than
+one of them. The /* multiline */ style is used at the start for the metadata,
+but not so much in the code itself. They don't nest cleanly, are easy to leave
+accidentally unterminated, need extra nonfunctional * to look right, and if
+you need _that_ much explanation maybe what you really need is a URL citation
+linking to a standards document? Long comments can fall out of sync with what
+the code is doing. Comments do not get regression tested. There's no such
+thing as self-documenting code (if nothing else, code with _no_ comments
+is a bit unfriendly to new readers), but "chocolate sauce isn't the answer
+to bad cooking" either. Don't use comments as a crutch to explain unclear
+code if the code can be fixed.</p>

+<title>Rob's ext2 documentation</title>
+
+<p>This page focuses on the ext2 on-disk format. The Linux kernel's filesystem
+implementation (the code to read and write it) is documented in the kernel
+source, Documentation/filesystems/ext2.txt.</p>
+
+<p>Note: for our purposes, ext3 and ext4 are just ext2 with some extra data
+fields.</p>
+
+<h2>Overview</h2>
+
+<h2>Blocks and Block Groups</h2>
+
+<p>Every ext2 filesystem consists of blocks, which are divided into block
+groups. Blocks can be 1k, 2k, or 4k in length.<super><a href="#1">[1]</a></super>
+All ext2 disk layout is done in terms of these logical blocks, never in
+terms of 512-byte logical blocks.</p>
+
+<p>Each block group contains as many blocks as one block can hold a
+bitmap for, so at a 1k block size a block group contains 8192 blocks (1024
+bytes * 8 bits), and at 4k block size a block group contains 32768 blocks.
+Groups are numbered starting at 0, and occur one after another on disk,
+in order, with no gaps between them.</p>
+
+<p>Block groups contain the following structures, in order:</p>
+
+<ul>
+<li>Superblock (sometimes)</li>
+<li>Group table (sometimes)</li>
+<li>Block bitmap</li>
+<li>Inode bitmap</li>
+<li>Inode table</li>
+<li>Data blocks</li>
+</ul>
+
+<p>Not all block groups contain all structures. Specifically, the first two
+(superblock and group table) only occur in some groups, and other block
+groups start with the block bitmap and go from there. This frees up more
+data blocks to hold actual file and directory data, see the superblock
+description for details.</p>
+
+<p>Each structure in this list is stored in its' own block (or blocks in the
+case of the group and inode tables), and doesn't share blocks with any other
+structure. This can involve padding the end of the block with zeroes, or
+extending tables with extra entries to fill up the rest of the block.</p>
+
+<p>The linux/ext2_fs.h #include file defines struct ext2_super_block,
+struct ext2_group_desc, struct ext2_inode, struct ext2_dir_entry_2, and a lot
+of constants. Toybox doesn't use this file directly, instead it has an e2fs.h
+include of its own containting cleaned-up versions of the data it needs.</p>
+
+<h2>Superblock</h2>
+
+<p>The superblock contains a 1024 byte structure, which toybox calls
+"struct ext2_superblock". Where exactly this structure is to be found is
+a bit complicated for historical reasons.</p>
+
+<p>For copies of the superblock stored in block groups after the first,
+the superblock structure starts at the beginning of the first block of the
+group, with zero padding afterwards if necessary (I.E. if the block size is
+larger than 1k). In modern "sparse superblock" filesystems (everything
+anyone still cares about), the superblock occurs in group 0 and in later groups
+that are powers of 3, 5, and 7. (So groups 0, 1, 3, 5, 7, 9, 25, 27, 49, 81,
+125, 243, 343...) Any block group starting with a superblock will also
+have a group descriptor table, and ones that don't won't.</p>
+
+<p>The very first superblock is weird. This is because if you format an entire
+block device (rather than a partition), you stomp the very start of the disk
+which contains the boot sector and the partition table. Back when ext2 on
+floppies was common, this was a big deal.</p>
+
+<p>So the very first 1024 bytes of the very first block are always left alone.
+When the block size is 1024 bytes, then that block is left alone and the
+superblock is stored in the second block instead<super><a href="#2">[2]</a>.
+When the block size is larger than 1024 bytes, the first superblock starts
+1024 bytes into the block, with the original data preserved by mke2fs and
+appropriate zero padding added to the end of the block (if necessary).</p>
+
+<h2>Group descriptor table</h2>
+<h2>Block bitmap</h2>
+<h2>Inode bitmap</h2>
+<h2>Inode table</h2>
+<h2>Data blocks</h2>
+
+<h2>Directories</h2>
+
+<p>For performance reasons, directory entries are 4-byte aligned (rec_len is
+a multiple of 4), so up to 3 bytes of padding (zeroes) can be added at the end
+of each name. (This affects rec_len but not the name_len.)</p>
+
+<p>The last directory entry in each block is padded up to block size. If there
+isn't enough space for another struct ext2_dentry the last </p>
+
+<p>Question: is the length stored in the inode also padded up to block size?</p>
+
+<hr />
+<p><a name="1" />Footnote 1: On some systems blocks can be larger than 4k, but
+for implementation reasons not larger than PAGE_SIZE. So the Alpha can have
+8k blocks but most other systems couldn't mount them, thus you don't see this
+out in the wild much anymore.</p>
+
+<p><a name="2" />Footnote 2: In this case, the first_data_block field in the
+superblock structure will be set to 1. Otherwise it's always 0. How this
+could POSSIBLY be useful information is an open question, since A) you have to
+read the superblock before you can get this information, so you know where
+it came from, B) the first copy of the superblock always starts at offset 1024
+no matter what, and if your block size is 1024 you already know you skipped the
+first block.</p>

+<h2>Q: "Why is there toybox? What was wrong with busybox?"</h2>
+
+<p>A: To answer the first part: Toybox dates back to when its maintainer
+<a href=https://lwn.net/Articles/202106/>handed off BusyBox maintainership</a>
+and <a href=http://landley.net/notes-2006.html#28-09-2006>started over from
+scratch</a> on a new codebase after a
+<a href=http://lists.busybox.net/pipermail/busybox/2006-September/058617.html>protracted licensing argument</a> took all the fun out of
+working on BusyBox. Toybox was just a personal project until it got
+<a href=https://lwn.net/Articles/478308/>relicensed years
+later</a> after its author did a lot of thinking
+<a href=http://landley.net/talks/ohio-2013.txt>about licenses</a>
+and about <a href=http://landley.net/notes-2011.html#21-03-2011>the
+transition to smartphones</a>. This led to the
+<a href=http://landley.net/talks/celf-2013.txt>2013</a>
+<a href=https://www.youtube.com/watch?v=SGmtP5Lg_t0>talk</a> laying
+out a strategy to make Android self-hosting, which helped
+<a href=https://code.google.com/p/android/issues/detail?id=76861>bring
+it to Android's attention</a>, and they
+<a href=https://lwn.net/Articles/629362/>merged it</a> into Android M.</p>
+
+<p>To answer the second part: BusyBox predates Android
+by almost a decade, but Android still doesn't ship with it because GPLv3 came
+out around the same time Android did and caused many people to throw
+out the GPLv2 baby with the GPLv3 bathwater.
+Android <a href=https://source.android.com/source/licenses.html>explicitly
+discourages</a> use of GPL and LGPL licenses in its products, and has gradually
+reimplemented historical GPL components such as its bluetooth stack under the
+Apache license. Similarly, Apple froze xcode at the last GPLv2 releases
+(GCC 4.2.1 with binutils 2.17) for over 5 years while it sponsored the
+development of new projects (clang/llvm/lld) to replace them,
+implemented its SMB server from scratch to replace samba,
+<a href=http://meta.ath0.com/2012/02/05/apples-great-gpl-purge/>and so
+on</a>. Toybox itself exists because somebody with in a legacy position
+just wouldn't shut up about GPLv3, otherwise its maintainer would probably
+still happily be maintaining BusyBox. (For more on how said maintainer wound
+up working on busybox in the first place,
+<a href=http://landley.net/aboriginal/history.html>see here</a>.)</p>

+</blockquote>
+
+<p>The text of the above license is included in the file LICENSE in the source.</p>
+
+<h2>Why 0BSD?</h2>
+
+<p>As with <a href=https://creativecommons.org/publicdomain/zero/1.0/>CC0</a>,
+<a href=http://unlicense.org>unlicense</a>, and <a href=http://wtfpl.net/>wtfpl</a>,
+the intent is to place the licensed material into the public domain,
+which after decades of FUD (such as the time OSI's ex-lawyer compared
+<a href=http://www.cod5.org/archive/>placing code into the public domain</a> to
+<a href=http://www.linuxjournal.com/article/6225>abandoning trash by the
+side of a highway</a>) is considered somehow unsafe. But if some random third
+party
+<a href=https://github.com/mkj/dropbear/blob/master/libtomcrypt/LICENSE>takes
+public domain code</a> and slaps <a href=http://www.opensource.apple.com/source/gnuzip/gnuzip-25/gzip/gzip.c>some other license on it</a>, then it's fine.</p>
+
+<p>To work around this perception, the above license is a standard 2-clause BSD
+license <a href=https://github.com/landley/toybox/commit/ee86b1d8e25cb0ca9d418b33eb0dc5e7716ddc1e>minus the half sentence</a>
+requiring text copied verbatim into derived works. If 2BSD is
+ok, the 0BSD should be ok, despite being equivalent to placing code in the
+public domain.</p>
+
+<p>Modifying the license in this way avoids the hole android toolbox fell into where
+<a href=https://github.com/android/platform_system_core/blob/fd4c6b0a3a25921a9fe24691a695d715aecb6afe/toolbox/NOTICE>33 copies of BSD license text</a>
+were concatenated together when copyright dates changed, or the strange
+solution the busybox developers used to resolve tension between GPLv2's "no
+additional restrictions" and BSD's "you must include this large hunk of text"
+by sticking the two licenses at
+<a href=http://git.busybox.net/busybox/tree/networking/ping.c?id=887a1ad57fe978cd320be358effbe66df8a068bf>opposite ends of the file</a> and hoping nobody
+noticed.</a>

+quite definitely is the answer. I think the problem, to be quite honest with
+you, is that you've never actually known what the question is."
+- The Hitchhiker's Guide to the Galaxy.</p></blockquote>
+
+<p><a href=downloads/toybox-0.7.0.tar.gz>Toybox 0.7.0</a>
+(<a href=https://github.com/landley/toybox/releases/tag/0.7.0>git commit</a>)
+is out.</p>
+
+<p>The new commands in defconfig are <b>iotop</b>, <b>top</b>, <b>pgrep</b>,
+and <b>pkill</b>
+(most replacing corresponding versions from pending). Added grep -ABC,
+swapon -d (discard), mkswap -L (label) and UUID support, and find -delete.
+Izabera added free -h and unshare -f. Josh Gao implemented tail -f.
+Jose Bollo submitted cp --preserve=context,attr. Kylie McClain added
+mktemp -u.</p>
+
+<p>In pending there's the start of a vi command, and Sameer Pradhan contributed
+a new dhcp6. This cycle saw several rounds of route cleanup and a little dhcp
+cleanup, but neither are complete yet. Lipi Lee did some cleanup to netstat.c
+and Elliott Hughes removed warnings from traceroute.</p>
+
+<p>Lots of updates to ps: several new -o options, -k (--sort) -O and -M,
+improved compatibility with Android's historical behavior, and
+extensive internal code cleanup (including the removal of all
+the magic constants).</p>
+
+<h3><b>Website</b></h3>
+
+<p>Dreamhost restored the <a href="#12-21-2015">missing 11 months</a>
+to the mailing list archive, in the process deleting the month after
+that. Now they've asked if I have mbox files archiving the new
+gap (between December 20, 2015 to January 21, 2016, and presumably they
+could also fill in the gap from December 14, 2014 to January 3, 2015 that's
+been there since the last time they did this),
+but due to some gmail filtering I've
+<a href=http://landley.net/notes-2012.html#15-10-2012>never
+been able to disable</a>, my copy of those files is spread among 3 different
+mbox files I'd have to sort/filter/collate. (It's on the todo list.)</p>
+
+<p>Added a code of conduct to the README (we're
+<a href=https://engineering.twitter.com/opensource/code-of-conduct>borrowing twitter's</a>) because somebody
+made it necessary.</p>
+
+<h3><b>Bugfixes</b></h3>
+<p>Fixed another sed bug where any ] right after [ was skipped (not just the
+first one in the range, so [[] didn't terminate). Fixed sort -f and added test cases.
+Assume 80 columns in "ls -m | cat", ls -L is no longer backwards,
+and ls of files with no paths no longer uses an uninitialized (zero) dirfd.
+Several bugfixes
+to find (Gilad Arnold fixed -perm, Daniel K. Levy fixed "find . -exec echo {}",
+and while we're there I fixed find --prune, made "find . -execdir
+echo {} + -execdir ls {} +" work, and ripped out the environment size
+measuring code that checked for a 128k limit removed back in linux 2.6.22).
+Elliott Hughes fixed the date command's parsing of 4 digit
+years and documented the %s escape, fixed hwclock -u, and pointed out
+that runcon needs to exec to do its job (not recursively call another
+command_main() in the same process). Tom Marshall reported that blkid was
+handling ext2 wrong. Mike Moreton corrected cpio extraction's uid and gid
+values, and added a --no-preserve-owner option. Fixed the SUID permission
+dropping logic (which was a bit over-zealous, preventing some commands from
+running at all).</p>
+
+<p>I'm told that debian-testing broke its libc so the nsenter build breaks,
+but my attempts to install the debian-testing network cd image under
+qemu keep breaking. Maybe someday they'll fix it enough I can actually
+reproduce the problem. (Debootstrap under unbuntu builds an ubuntu-flavored
+chroot in which toybox builds fine.)</p>
+
+<h3><b>Documentation</b></h3>
+<p>Rewrite of the about.html page, tweaks to design.html, and a re-triage of
+sbase in roadmap.html. Update to mkstatus.py to collate multiple span
+tags with the same id, resulting in a larger status.html page (which
+was previously ignoring some commands in the roadmap).</p>
+
+<p>Expanded the defconfig/allyesconfig/allnoconfighelp text in "make help"
+to explain what they're for.</p>
+
+<h3><b>infrastructure</b></h3>
+<ul>
+<li><p>Expanded toys.optargs to 64 bits so a command can have more than 32 options.</p></li>
+<li><p>Added NOEXIT() wrapper to turn xwrap() functions into warning versions
+using the existing longjump(toys.rebound) infrastructure.</p></li>
+<li><p>Renamed dirtree->data to dirfd and stopped storing symlink length
+into it (this fixed a bug where following symlinks to directories
+didn't give a valid directory filehandle, noticeable with ls -Z).</p></li>
+<li><p>New TAGGED_ARRAY() infrastructure generates index and bitmask macros
+for arrays of structures starting with a name string.</p></li>
+<li><p>New lib/linestack.c for utf8 fontmetrics (draw_str() and utf8len()
+and so on), and for tracking multiple lines of text
+(vi, less, shell history) that need wordwrapping and scrolling up/down.</p></li>
+<li><p>Upgrades to lib/interestingtimes.c: scan_key() now has a timeout
+in miliseconds and recognizes more sequences including ANSI
+window size probes. New utf8 test files in tests/files/utf8 including
+sequence reversing, stacked combining chars, and all three types of
+unprintable sequences (low ascii <32 ala ^X, invalid utf8 sequences ala
+<AB><CD>, and invalid unicode code points ala U+1234).</p></li>
+<li><p>More comma handling code in lib.c: comma_args()</p></li>
+<li><p>Added error_msg_raw() to shut up fortify's endless static checking false
+positives.</p></li>
+<li><p>readfileat() can now realloc() in a loop to read long files
+("zcat | insmod" needed it).</p></li>
+</ul>
+
+<h3><b>Roadmap</b></h3>
+<p>We're getting close to having a self-hosting development environment
+using toybox for the command line. The remaining busybox commands in
+<a href=http://landley.net/aboriginal/about.html>Aboriginal Linux</a> are:</p>
+
+<blockquote><p><b>
+awk bunzip2 bzcat bzip2 dd diff expr fdisk ftpd ftpget ftpput gunzip gzip
+less ping route sh sha512sum tar test tr unxz vi wget xzcat zcat
+</b></p></blockquote>
+
+<p>And the remaining non-busybox commands in Aboriginal Linux's build/host
+directory (from the distcc, genext2fs, e2fsprogs, zlib, and squashfs packagesi)
+are:</p>
+
+<blockquote><p><b>
+mke2fs fsck.ext2 resize2fs distcc genext2fs unsquashfs distccd mksquashfs tune2fs
+</b></p></blockquote>
+
+<p>Squashfs and distcc are probably out of scope for toybox, but mke2fs,
+fsck.ext2, resize2fs, genext2fs, and tune2fs should all be added to the
+above "busybox" replacement list.</p>
+
+<p>Remind me to include this countdown in future releases. Once they've all
+been replaced, the next goal is <a href=http://landley.net/aboriginal/about.html#selfhost>building AOSP under itself</a>.</p>
+

+
+<p>Yes, 11 months have gone missing from the mailing list web archive.</p>
+
+<p>Yesterday evening Dreamhost's mailman server went down (timing out trying
+to connect). I poked them about it, they
+<a href=https://twitter.com/landley/status/678781271670149121>blamed
+DNS</a>, I explained that the hang was _after_ the DNS lookup and
+entered the dig info into the trouble ticket showing the IPs the DNS
+queries were returning, they reinstalled the server at that IP from what I
+assume was their most recent backup, and that's how 11 months of messages
+vanished out of the archive.</p>
+
+<p>I've <a href=https://twitter.com/landley/status/679114451975467008>continued to poke them about it</a> but I honestly believe that's the best they
+can do. <a href=http://landley.net/dreamhost.txt>Last time</a>
+this sort of thing <a href=http://landley.net/dreamhost2.txt>happened</a>
+we went back and forth for months, so I added a link to a backup web
+archive (in the nav bar on the left) that isn't controlled by dreamhost,
+and thus doesn't gratuitously lose data on a regular basis. (I note
+the earlier hole in Dreamhost's archive was never fixed either. That
+was data never getting archived, this is a year's worth of data that
+was in the archive until yesterday vanishing after the fact.)</p>
+
+<p>If you're wondering why the <a href=http://lists.landley.net>top level</a>
+list page has been "temporarily disabled" for multiple years now... you'd have
+to ask Dreamhost. I know I have. More than a dozen times.</p>

+of Betelgeuse?" Arthur shrugged in a so-so sort of way. "I don't know," he
+said, taking a pull of beer. "Why - do you think it's the sort of thing you're

+
+<p><a href=downloads/toybox-0.6.1.tar.gz>Toybox 0.6.1</a>
+(<a href=https://github.com/landley/toybox/releases/tag/0.6.1>git commit</a>)
+is out.</p>
+
+<p>We have a new <b>ps</b> command with all the -o fields posix wants (although
+it doesn't accept BSD non-dash option syntax yet), and <b>bunzip2</b> (not just
+bzcat but the proper extract-in-place command).
+Sameer Pradhan added <b>hostid</b> and <b>fsync</b>.
+Elliott Hughes added <b>flock</b>.
+
+<p>The people waiting for <b>human readable number support</b> (du -hH, ls -h,
+and so on) can thank Elliott Hughes for implementing it. (Our output doesn't
+exactly match others' because we our "binary" mode will say 1.0G instead of
+1024M, which is a bug in the other one we didn't emulate.)</p>
+
+<p>The other big news is <b>nommu support</b>, tested on the new
+<a href=http://nommu.org/jcore>jcore</a> processor but presumaby working
+on any nommu system. A few commands don't support nommu yet, but those
+are disabled by dependencies on TOYBOX_FORK in menuconfig when building
+for nommu. The roadmap now has a large section analyzing the uClinux
+project (note that <a href=http://nommu.org>nommu.org</a> is slowly replacing
+<a href=http://uclinux.org>uclinux.org</a> as the standard repository of
+all knowledge and wisdom about nommu. The old site <a href=#12-02-2012>contains
+much that is apocryphal</a>, or at least wildly inaccurate, and the new one
+is trying to improve on that).</p>
+
+<p>Both "make change" and scripts/single.sh (for building standalone commands
+without the multiplexer logic) now use the top level .config
+for toybox global settings such as Linux Security Blanket Module selection,
+(so make defconfig before change now).</p>
+
+<p>Documentation updates to the <a href=code.html>code</a> and
+<a href=roadmap.html>roadmap</a> pages.</p>
+
+<h3>pending</h3>
+
+<p>In the pending directory Sameer Pradhan added tftp,
+and Elliott Hughes sent lsof. Isaac Dunham upgraded mdev,
+reboot, init, login, and modprobe, and fixed a distro-specific build break in
+scripts/mkflags.h. Elliott Hughes and Lipi Lee made netstat -p handle
+command lines longer than 21 characters, and Elliott fixed netstat -e and
+some build warnings. Yeongdeok Suh fixed a warning in dhcpd.
+I started cleanup on pgrep/pkill.</p>
+
+<h3>Command updates, bugfixes, and infrastructure</h3>
+
+<p>The multiplexer's "command not found" error exit is now 127, so now you can't
+distinguish between a command not being found in the multiplexer and
+the multiplexer itself not being found by the shell, because people wanted
+that for some reason.</p>
+
+<p>Elliott Hughes made date reject invalid dates rather
+than set the clock to something weird (setting the clock 100 years into the
+future makes most Linux desktops surprisingly unhappy, and ntpdate won't fix it
+either), fixed several ls -l display issues (user/group field ordering,
+make user/group/lsmcontext left aligned), did the aforementioned
+extensive work on human readable number output, fixed ionice's default
+class, fixed a mv overwrite bug, made df's columns auto-size, added
+--ppid and -Z to ps, and teamed up with Daniel K. Levy to fix
+a segfault in find's handling of -newer -group or -user.</p>
+
+<p>Hyejin Kim added stat -c %T support. Colin Cross worked
+on vmstat fixing
+a header printing bug and calculating the bi and bo columns in the right
+units. Isabella Parakiss reported that sed -e "/x/c\" -e "y" added an extra
+newline and that grep -w '\(x\)\1' didn't work, both now fixed.
+Alistair Strachan fixed several problems with switch_root. Kylie McClain
+pointed out env should be able to clear variables via NAME= syntax.
+Dima Krasner added support for running blkid without a partition (so it shows
+all partitions). Hyejin Kim sent in a bunch of static analysis bug reports.</p>
+

+Dima Krasner added support for running blkid without a partition (so it shows
+all partitions). Hyejin Kim sent in a bunch of static analysis bug reports.</p>
+
+<p>Two large thinko fixes in oneit: -3 was always enabled (which would
+eventually block if the child never read the exiting PID numbers from its file
+descriptor #3 until the pipe filled up), and the signal handlers weren't
+set up right (for requesting semi-graceful halt/poweroff/reboot).
+Calling install without a mode is now 0755, and install -g 0 no longer clashes
+with cp --preserve. Better error message for ls -r on unreadable
+directories, and ls -Z now uses O_PATH (with the /proc/self/fd/%d
+workaround for kernel stupidity as necessary).</p>
+
+<p>Date now understands @unixtime[.fraction] and uses -D for
+the set-side format (matching busybox's extension for this). The seq -f
+string now checks that it's got exactly one %f escape with the correct
+attributes (and a whole bunch of test cases for it). Fixed a bug
+in od that screwed up the position indicator on arm and mips.
+In stat the d/h units moved from %d %D to the default string.
+And patch can now correctly apply hunks with trailing context to the start of
+the file.</p>
+
+<p>The prompt argument moved out of yesno() (the caller can print the prompt
+themselves). Replaced toys.exithelp with help_exit(). Added new
+XVFORK() macro, and xpopen_both() calls /proc/self/exe when passed
+a NULL argv (see cpio -p for example usage). Replaced toys.recurse
+with toys.stacktop so the recurse or re-exec decision is now based
+on bytes of stack space used. Marked a bunch of command-local functions
+static.</p>
+
+<p>New additions to lib/ include strlower(), xconnect(), and the
+aforementioned help_exit().
+The testsuite now has some infrastructure tests based on "example"
+commands such as toys/examples/test_human_readable.c.
+The login command finally got a long-overdue cleanup (it's one of the
+commands that predate the "pending" directory but were part of the reason
+for it). Hexedit had an
+uninitialized variable (of course gcc didn't spot it, it was too busy
+warning about "may be used uninitialized but never actually is" variables).</p>
+
+<p>Tweaked makefile so
+"make CROSS_COMPILE=prefix-" (as well as "CROSS_COMPILE=prefix- make",
+which still works). Toybox is now installed chmod -w so broken installers
+(like the bunzip2 package's) that try to overwrite existing binaries won't
+knock out the whole of toybox.
+GCC 5.2.0 stopped being able to compile Linux 2.6.12's kconfig, but
+we added a workaround. You can now build uptime without utmpx.h.
+Alejandro Joya pointed out that enabling smack required smack on the host
+as well as target when cross compiling, which is now fixed.</p>
+
+<p>Note: toybox can autodetect nommu support when building with a uClibc
+toolchain such as <a href=http://landley.net/aboriginal/downloads/binaries/old/1.4.3/cross-compiler-sh2eb.tar.gz>the one from Aboriginal Linux</a>,
+but <a href=http://github.com/richfelker/musl-cross-make>with musl-libc</a>
+you'll have to enable CONFIG_TOYBOX_MUSL_NOMMU_IS_BROKEN to work around the
+fact they provide a non-functional fork() implementation that always returns
+-ENOSYS, to prevent you from compile-time probing for nommu support when
+cross-compiling. Unfortunately "preventing you from probing" seems to be
+an explicit policy with musl, they also don't provide an "#ifdef __MUSL__"
+because their library is perfect and you're only ever allowed to work around
+other people's bugs, not theirs. So we have to use menuconfig to manually
+enable musl-specific bug workarounds.</p>

+
+<h3><b>New stuff this release</b></h3>
+
+<p>There's a new android menu in menuconfig, and rather a lot of Linux
+Security Module support (Smack for Tizen from Xavier Roche and José Bollo,
+and SELinux for Android from Elliott Hughes; see
+the Security Blanket menu under global settings in menuconfig) has
+trickled in, although there's still more to come.</p>
+
+<p><b>New commands:</b> Added reset, nproc, ionice, and iorenice.
+Elliott Hughes contributed xxd, runcon,
+restorecon, load_policy, getenforce, setenforce, getprop, and setprop.
+Promoted shred, nsenter, and hwclock.</p>
+
+<p>You can once again build catv now the flag infrastructure's been updated to
+let it coexist with cat -v.
+And on a long plane flight I wrote
+hexedit, an interactive hex editor that implements the start of
+cursor control infrastructure (for eventual use by less and vi and shell
+command history and so on).</p>
+
+<p><b>New options:</b> Added sed -E as a BSD-compatible synonym for -r.
+Upgraded oneit with -r (restart), -3 (send exiting PID values to child),
+and signal handling. Added -v option to timeout, -m to mknod, -u to shred,
+-t to dmesg, and -123 to head and tail. Added implicit "." to grep -r without
+any files to work on. Hyejin Kim requested prefix support for truncate -s.
+Greg Hackman added -inum to find.
+Jan Cybulski added the smack side of ls -Z support. Various patches also
+added -Z to mkdir, mknod, and mkfifo.
+Basic cp --preserve support went in, but not yet the xattr/LSM parts.</p>
+
+<p>The toybox command now has a --version option,
+which uses "git describe" if available.</p>
+
+<p><b>Build infrastructure:</b>
+The "make change" target now saves the output of each failed standalone
+command build in a .bad file, and "make defconfig" is quieter now.</p>
+
+<p>Paul Barker submitted a large patch changing command install paths so
+"toybox can be installed alongside busybox without confusing
+update-alternatives". (There's some argument over
+what the right paths should be, and I'm waiting for
+people to tell me what else needs fixing because I have no idea. I've
+been symlinking /bin to /usr/bin since 2002
+<a href=http://landley.net/writing/hackermonthly-issue022-pg33.pdf>for
+historical reasons</a>.)</p>
+
+<p><b>Docs:</b> The repository link now goes to github, with another link
+to the commit rss feed.</p>
+
+<p>Elliott Hughes updated the Android section of the roadmap
+(and he would know). Redid bits of scripts/mkstatus.py to make updating
+status.html easier, and the README is larger.</p>
+
+<p>More description of option parsing in code.html, which now describes the
+FLAG_x macros, switching flag macro sets with FOR_newcommand, how
+configuration zeroes flag macros and using FORCE_FLAGS to suppress the
+zeroing of options shared between commands. Also added description of ";"
+to make --longopts take an optional =value part, and more about TOYBOX_DEBUG
+to check NEWTOY() option strings (otherwise a bad option string makes
+lib/args.c obviously segfault, but doesn't explain why).</p>
+
+<p>Added a "Why 0BSD?" section to license.html when submitting zero clause bsd
+to SPDX (according to the pending license spreadsheet, it's been approved for
+SPDX 2.2).</p>
+
+<p>The old list of commands needing cleanup but not in pending was
+removed from toys/pending/README and instead the issues were added
+as TODO comments in the individual commands.</p>
+
+<p><b>Bugfixes:</b>
+Fixed mount -a segfaulting without -O (reported by Janus Troelsen),
+and made it try a "become rw" ioctl() on the block device before falling
+back to mounting read only (because Android expects that).
+Fixed printf -- and printf ---. Lots of tweaks to ls -l spacing with
+different options. Make touch -d and -t actually set time when you don't
+specify nanoseconds.
+Fixed a subtle bug where recursive calls (toybox commands that run other
+toybox commands) weren't resetting all their state. (This manifested as
+a "no }" error from "find | xargs sed", but could cause other problems.)
+And David Halls reported another sed bug trying to compile libiconv (which
+left extra \ at the start of lines in a generated shell script, breaking
+the build). Output an error message for "cat /mnt".</p>
+
+<p>Kylie McClain reported that mktemp broke when $TMPDIR was set to an empty
+string (which is not the same as unset), that install/find didn't support
+numeric uid/gids, and that sort -z affects both input and output.
+Isabella Parakiss fixed a printf.c bug.
+David Halls fixed bugs in install -D and find -exec. Samuel Holland
+fixed unshare -r. Hyejin Kim fixed makedevs with a count of 1, fold -w
+range checking, an error path in scripts/mkflags.c, added -i to dhcpd,
+and stopped su from prompting the root user for the new user's password.
+Jan Cybulski spotted wrong indentation when combining ls -s and -i with -C and
+-x. José Bollo fixed stat %G. Sameer Pradhan fixed a bug in mkfifo -Z.</p>
+
+<p>Elliott Hughes asked for a default SIGPIPE handler to disable
+the signal handler bionic's dynamic loader installs (yes really). Still not
+100% sure what the correct behavior is there. (Posix is
+(<a href=http://permalink.gmane.org/gmane.comp.standards.posix.austin.general/10915>actively unhelpful</a>, but at least they're taking
+<a href=http://austingroupbugs.net/view.php?id=789#c1976>years to
+make up their mind</a>. Elliott also sent patches to fix a typo in
+useradd.test, add missing arguments to error_exit() calls and clean up
+printf() format strings, fix an off by one error in human_readable(),
+fix dmesg -c error reporting, fix a segfault in comma_scan where the option
+was the last item in optlist (triggered by mount -o ro,remount), fix
+hwclock -w, made ifconfig print lowercase MAC addresses (it was bothering
+him), and make terminal_size() read the right environment variable
+(LINES, not ROWS). And he suggested the test suite notice high command exit
+values (corresponding to segfault or other signals).</p>
+
+<p>People are apparently using toys/pending commands, despite the police tape
+and flashing lights, so added louder warnings to toys/pending/README.
+Elliott Hughes fixed various problems with tar, dd, more, and top.
+Hyejin Kim cleaned up syslogd and dumpleases. Isaac Dunham added hotplug
+support to mdev. Yeongdeok Suh added RFC-3315 ipv6 support to dhcpd.</p>
+
+<p>I rewrote ps.c from scratch (in pending), but it's not ready for real use
+yet.</p>
+
+<p><b>Portability:</b>
+On the portability front Bernhard Rosenkranzer fixed a problem where the
+menuconfig code wouldn't compile in C99 mode. (This led to me documenting
+the craptacular nature of kconfig in a README, and the plan to replace it
+sometime before 1.0.) Some extra flags to shut up overzealous llvm warnings
+were added (and have to be probed for because gcc complains about
+arguments it doesn't recognize even when they switch stuff _off_ using
+a standard syntax). Don't depend on malloc(0) to return non-null in ls.
+David Halls fixed some mac/ios portability issues,
+implying somebody's built at least part of toybox on a mac.</p>
+
+<p>Added basename_r() to lib/lib.c because the posix semantics for basename()
+are stupid but what the gnu guys did to it was appalling.
+Turns out bionic already had a basename_r(), but posix still doesn't.
+Fixed it up in portability.h, but this
+could break more stuff in future. (Correct fix is to lobby posix to add it,
+which would probably take about 15 years...)</p>
+
+<p><b>Infrastructure:</b>
+The build now checks $LDFLAGS for linker-only flags, and allows the strip
+command to fail (binflt toolchains provide a strip that doesn't work).
+Since time.c uses floating point, added TOYBOX_FLOAT dependency in config.</p>
+
+<p>There's a lib/lsm.h defining varous inline functions for linux
+security modules stuff, if (lsm_enabled()) should turn into a compile-time
+constant 0 and let code drop out when TOYBOX_LSM_NONE selected, but
+testing against CFG_TOYBOX_LSM_NONE or derived symbols is still useful
+becuase when it _is_ enabled the probe turns into a system call you
+don't want to repeat too much.</p>
+
+<p>Switched a bunch of commands from signal() to xsignal(). Factored out
+xgetgrnamid() and xgetpwnamid() into xwrap.c. Make time.c depend on
+TOYBOX_FLOAT (since it always uses float so shouldn't be available on
+build targets without even software float). Added readfileat() to lib/lib.c.</p>
+
+<p>The dirtree infrastructure now passes in full flags for the old symlink
+field, and the new DIRTREE_SHUTUP flag disables warnings if a file vanishes
+out from under you during traverse. New dirtree_start() wrapper to
+create dirtree root with only two arguments.</p>
+
+<p>The not-curses infrastructure introduced by hexedit mostly moved to
+lib/interestingtimes.c.</p>

+Tim contacted me (my blog says a couple days before nov 13, 2011, I.E.
+11/11/11 not some specific day 2 months later) to ask if I wanted to work
+on a new project he was proposing called
+<a href=http://www.elinux.org/Busybox_replacement_project>BentoBox</a>
+(because I used to do busybox, he'd forgotten toybox existed
+until I brought it up). And don't ask me what "focuses not on compatibility
+with its GNU counterparts" means when CP_MORE adds 7 non-posix options
+and toys/other has 84 commands in neither posix nor LSB. I think they're
+struggling to explain the difference having dismissed "licensing" as being
+the reason it started up again after a long hiatus? The reason I don't think
+GNU is special is there are a half-dozen other independent
+implementations of the same unix command tools out there (AT&T,
+BSD, Coherent, Minix, plan 9, busybox, toybox, and several more analyzed in
+the <a href=roadmap.html>roadmap</a>, and that's ignoring the implementations
+written for DOS or in assembly over the years). But I do care what
+Linux From Scratch expects, and if it's
+<a href=http://archive.linuxfromscratch.org/lfs-museum/7.6/LFS-BOOK-7.6-NOCHUNKS.html#ch-tools-gcc-pass1>calling mv -v</a>
+then I impelement mv -v
+even if <a href=http://landley.net/toybox/roadmap.html>posix hasn't got
+it</a>. And I don't know why "gnu counterparts" would describe this when
+util-linux isn't a gnu package, nor are info-zip, e2fsprogs, kmod, less,
+procps, shadow, sysklogd, vim, zlib, sudo, dhcpcd...</p>

+(<a href=/hg/toybox/shortlog/1702>commit 1702</a>) is out.</p>
+
+<p>New promoted commands: sed (finally fixed enough it builds Linux From
+Scratch), printf (cleaned up and promoted), shred and
+base64 (the Tizen guys wanted them), getenforce, setenforce, and chcon (android),
+mix (promoted with fixes from Isaac Dunham), nsenter (from
+Andy Lutomirski, merged into unshare).</p>
+
+<p>Elliott Hughes submited a bunch of patches to support Android (to
+both toybox and Bionic libc, which he maintains). On toybox's end this
+involved a lot of fixups to portability.[ch] and fixes to over a dozen
+commands, plus several new ones. Other portability fixes included working
+with buildroot's uclibc fork and building for nommu targets.</p>
+
+<p>The new "make change" target builds each toybox command as a standalone
+binary. Rather a lot of commands that didn't build by themselves (mv depending
+on cp and so on) were hit with a large rock until they built standalone.
+This involved rewriting bits of option parsing, more elaborate dependency
+generation, making each command have its own config
+symbol and main() function (even when it's just a wrapper calling another
+command's main()), and so on. Also, some commands can't be built standalone
+at a conceptual level: "help" describes other enabled commands and "sh"
+has a number of bulitin commands (cd, exit, set) that require the
+multiplexer infrastructure, so "make change" filters them out.</p>
+
+<p>The mailing list's web archive is still screwed up. Dreamhost has
+been trying to fix it since approximately September. There are
+<a href=http://www.mail-archive.com/toybox@lists.landley.net/>two</a>
+<a href=http://news.gmane.org/gmane.linux.toybox>other</a> less broken
+archives, but neither has quite the same UI as mailman.</p>
+
+<h3>Bugfixes and tweaks</h3>
+
+<p>Cynt Rynt sent in tests for ifconfig,
+Robert Thompson taught factor to accept whitespace separated arguments,
+Hyejin Kim pointed out that some of mktemp's longopts were attached to
+the wrong short options,
+Luis Felipe Strano Moraes fixed a wrong free() call in bootchartd in pending.
+Patches from Ashwini Sharma to make "df /dev/node" work, prevent du from
+looping endlessly following symlinks, and to make expr.c
+(in pending) understand == and regex matches. (Speaking of expr, it gets
+priority groupings wrong but the bug was actually in the posix spec's
+HTML conversion. They fixed the posix spec upstream for us. Still need
+to fix the expr code, but it's in pending for a reason...)</p>
+
+<p>Some commands grew new option flags, such as cp --remove-destination
+and touch -h.</p>
+
+<p>The parallel build has better error reporting now. When toybox needs to
+re-exec itself to regain suid root permissions and hasn't got the suid bit,
+it now gives the right error message ("not root" instead of "no such command").
+
+<p>Added a test to "mount" to not mount the same device/directory combination
+over itself (the OS catches this for block devices, but not for tmpfs).
+Make blkid distinguish ext3 from ext4. Added catv back into cat (because
+the Android guys wanted it, and they have historical usage on their side,
+so...). Handle nanoseconds in touch.</p>
+
+<p>Fixed a segfault when CP_MORE was disabled (the resulting option flag list
+no longer defined -d but still had it in option groups at the end).
+Workaround for glibc redefining dirname() and basename() to random non-posix
+semantics because gnu. (They could have created dirname_r() but didn't want
+to.)</p>
+
+<p>Fix an ifconfig test that was preventing assigning an ipv4 address to
+interface aliases. Several cleanup passes on hwclock but not quite
+promoted out of pending yet.<p>
+
+<p>Fixed a wrong error message in rm (if you had a chmod 000 directory and
+did rm -r on it without -f, after the prompt it would complain it was a
+directory, which was not the problem).</p>
+
+<p>The gzip compression code now does "store only" output to stdout, for
+what that's worth.</p>
+
+<p>Cleanup mountpoint and expand, and remove them from toys/pending/README
+(a list of commands that predate the toys/pending directory but needed
+another pass).</p>
+
+<h3>Library and infrastructure:</h3>
+
+<p>Reworked the option parsing infrastructure so more commands build
+standalone (via scripts/single.sh or "make change"). The option flag bit
+values are no longer packed, it leaves spaces where currently disabled
+flags go, and you can #define FORCE_FLAGS so disabled flags aren't zeroed.
+This allows multiple commands to more easily share infrastructure, even if
+your current flag context is for a disabled command (switched off in config),
+you can force them to stay on and as long as the flags read the same right
+to left they'll have the same values.</p>
+
+<p>We've started removing use of strncpy() because it's a hugely broken
+standard C function: the length is the maximum length to _append_, not
+the size of the destination buffer. It memsets the remaining space it didn't
+copy ala "memset(dest+strlen(dest), 0, len);" so
+if you think len is the size of dest you're guaranteed to stomp memory off the
+end). And if it runs out of space it won't null terminate because reasons.
+(Meanwhile sprintf("%*s", len, str) is counting wide characters in your current
+locale, so if you set a locale other than "C" it will also go past your
+allocated buffer size. Whoever is maintining the C library standards is really
+bad at strings.)
+Instead we have xstrncat() which will error_exit() if src+dest+1 doesn't
+fit in the buffer. (Because randomly truncating input data isn't necessarily
+an improvement.) And there's always xmprintf().</p>
+
+<p>Similarly, strtol() doesn't return an error indicator on overflow,
+you have to clear and then check errno. So new xstrtol() that cares
+about overflow.</p>
+
+<p>The bionic and musl guys agree faccessat(AT_SYMLINK_NOFOLLOW) is not
+supported, so stop using it.</p>
+
+<p>Fixed toy_exec() to detect when argc is in optargs, so we don't
+need a separate xexec_optargs().</p>

+<p>Dreamhost continues to be unable to make mailing list archives work, so
+here's <a href=http://www.mail-archive.com/toybox@lists.landley.net/>another
+list archive</a> with a less awkward interface than gmane.</p>
+
+<p>(Neither gives you the convenient historical monthly views of mailman,
+but I still have hopes dreamhost will someday figure out what they're doing
+wrong. They've only been trying since October. Last month they did a
+<a href=http://www.dreamhoststatus.com/2015/01/14/discussion-list-hardware-maintenance/>hardware upgrade to fix a software problem</a>, and the stale
+data loads much faster now, so that's something.)</p>
+
+<p>Update (Feb 19): the archive started updating again, by discarding
+all the pending data. So there are now _two_ giant holes in Dreamhost's

+<p>(Most of which was already on the todo list, but it helps prioritize.)</p>
+
+<p>Fixed md5sum and sha1sum on big endian systems (reported by James McMechan).
+Andy Lutomirski fixed unshare's help text and option parsing,
+and submitted nsenter (a tool to use setns(2)) to pending.
+Isaac Dunham implemented acpi -ctV options, and spotted the bug that ls -d
+was inappropraitely following command line symlinks without -H or -L (it
+should act like ls -l does), and ls -F handles symlinks wrong too.
+Lukasz Szpakowski sent in two bugfixes to tail.c. Cynt Rynt spotted an
+unnecessary assignment in lib/password.c.</p>
+
+<p>Ashwini Sharma's team was as busy as usual, submitting tr, crontab, and
+ipcrm, and hwclock to pending, more features to the pending ip.c, and a
+pile of bugfixes (to chgrp, killall, ifconfig, insmod,
+losetup, comm, cp, id, xwrap, netcat, modprobe, nohup...) mostly found by
+static analysis. (These fixes are mostly to seldom-used codepaths like the
+TOYBOX_FREE config option, but test coverage is always appreciated.) Ashwini
+also suggested upgrading ln -f to leave the original target alone if link
+creation fails, and reported that mv -f and -i weren't implemented (now fixed).</p>
+
+<p>New config option: TOYBOX_NORECURSE prevents xexec() from making internal
+function calls (for nommu systems with a finite stack).</p>
+
+<p>The "toybox" multiplexer command no longer adds a trailing space to each
+line of command names, so things like "./toybox | tr ' \n' '|'" to create
+a grep pattern snippet are easier to do. (Why you'd want to is your business,
+but the output is tidier now.)</p>
+
+<h3>Infrastructure</h3>
+
+<p>Isaac Dunham added Android support to portability.h, including compile
+probes for functions missing from bionic-libc, and annotated the commands that
+use those functions. We haven't really tested building against bionic,
+but in theory it's possible now.</p>
+
+<p>Running the test suite now color codes the PASS/SKIP/FAIL notifications
+if output is to a tty. (And in case you missed it last time, VERBOSE=fail
+to stop at the first failure is really useful.)</p>
+
+<p>In loopfiles_rw() use O_CLOEXEC instead of O_RDONLY to request the loop
+function close filehandles for us. (Otherwise the callback function must
+close each supplied filehandle itself.)</p>
+
+<p>The printf-style escape parsing ("\n" and friends) got factored out into
+a new unescape() function.</p>

+(<a href=/hg/toybox/shortlog/1512>commit 1512</a>) is out.</p>
+
+<h3>New commands</h3>
+
+<p>The new commands are find, install, factor, and mount. Promoted commands
+(cleaned up and moved out of "pending") are lspci, inotifyd, and blockdev.</p>
+
+<p>cp now implements -HL and -F to force delete of pending files, cpio now
+ignores -m and implements -p, ls -C now has utf8 support (using wcwidth
+instead of strlen), and umount got a number of upgrades involving
+looking things up in /proc/mounts. Other minor cleanups happend to
+cut, touch, free, and id.</p>
+
+<p>In pending: Bradley Controy submitted mix (adjusts OSS sound volume). Ashwini
+Sharma submitted diff, userdel, blockdev, ipcs, and crond, upgraded
+fdisk, fsck, and ftpget, and ran a static analyzer on a lot of other code.
+Partial cleanup was done to useradd, userdel, groupadd, and groupdel.</p>
+
+<h3>Build infrastructure</h3>
+
+<p><b>Parallel builds</b></p>
+
+<p>The build now takes advantage of SMP, autodetecting the number of
+processors. (Export the environment variable CPUS to pick a specific number.)
+Other build changes: split out $LDOPTIMIZE because old compilers complain
+about linker options passed with -c, and the entire "generated" directory now
+gets deleted by clean (the README that was in there got merged into code.html).</p>
+
+<p><b>Standalone builds</b></p>
+
+<p>The standalone build infrastructure (scripts/single.sh) got upgraded to
+build more commands as standalone executables. In make.sh the source file
+selection uses a regex to find the source files with the NEWTOY/OLDTOY macro
+for the command. It enables each command's
+sub-options (so CP has CP_MORE), enables I18N and FLOAT support to build
+full-featured commands, and includes --help text (at least when
+the command doesn't use another command's help). The OLDTOY() macro
+now produces (redundant) function prototypes so you can build an OLDTOY
+without the NEWTOY</p>
+
+<p>It doesn't quite have complete coverage yet, the defconfig entries that
+aren't building standalone yet are:</p>
+
+<blockquote><p>chown, egrep, fgrep, fstype, halt, mv, nc, poweroff, unix2dos,
+whoami</p></blockquote>
+
+<p>The main reason for standalone build failures is NEWTOY() or OLDTOY()
+entries that don't have their own config symbol. Another problem is entries
+that depend on another entry in kconfig, usually because common infrastructure
+is using one command's flags (which the other commands copy): if that command
+is disabled, the FLAG macros become 0 so dead code elimination can remove the
+code. It's <a href=http://landley.net/hg/toybox/rev/1503>possible
+to untangle</a> this, but a bit awkward. (It boils down to conflicting
+design goals in the two contexts.)</p>
+
+<p>Standalone builds are used by the test suite when testing individual
+commands.
+
+<p><b>Snapshot builds</b></p>
+
+<p>A new addition to the "generated" directory is generated/build.sh
+containing a single compiler command line to build toybox in its current
+configuration. Combined with the generated/*.{h,sh} files from an
+exisiting build, this may let you build on a new system that hasn't quite
+got enough OS bits working to run a full configureand make.</p>
+
+<h3>Internals</h3>
+
+<p>Library code: xcreate/xopen now O_CLOEXEC by default to avoid leaking
+filehandles to child processes. DIRTREE_COMEAGAIN's second callback is now
+done with the directory filehandle still open (new dir->again variable added
+to distinguish first from second callback, and requesting DIRTREE_RECURSE now
+requires passing in the specific macro value, not just a true/false).
+Use daemon() out of libc instead of hand-rolled daemonize() in various
+pending commands. string_to_mode() now passes through type bits so you can
+use it to more easily modify a file's existing mode.
+Split xpopen() into xpopen_both(), xopen(), and xrun() depending on whether
+we want to redirect both, one, or neither of stdin/stdout.</p>
+
+<p>Bugfixes: Better error message when TOYBOX_SUID option can't drop priviliges
+(which happens when you suid something _other_ than root).
+The old pending version of nbd_client.c wasn't deleted when the
+command was promoted (and the build would break if both were enabled),
+toy_exec() sometimes needs to re-exec from $PATH rather than recurse
+internally (to gain dropped root permissions or limit stack depth),
+always call setlocale() when I18N is enabled to switch it back _off_ when
+we run commands that expect sscanf("%n") to return bytes,
+dirtree() had a memory leak in an error path, patch.c had some bugs in
+error paths (didn't report problem clearly). Ashwini Sharma spotted an
+option parsing bug where [-abc] would forget _all_ command line arguments
+saved in the GLOBALS() block (not just the ones for options being switched
+off), plus various minor fixes to nbd_client and cpio.
+Lukasz Szpakowski fixed rm -f on a broken symlink (failed), and killall
+with no arguments (segfaulted).</p>
+
+<p><b>Portability</b></p>
+
+<p>A somewhat fiddly fix to rm -rf (which needs to chmod directories to u+rwx
+to descend into them) which hit a musl bug in faccessat() which the musl
+maintainer refuses to fix. (He literally wants the man page changed
+instead, despite other libcs working.) Added an #ifdef __MUSL__ section
+to portability.h with a workaround, you may need CFLAGS=-D__MUSL__ in your
+build if your musl build's features.h doesn't #define that. (I may do
+a different workaround in future, but sometimes you've just got to make
+it work so you can ship. Also, toybox grep with multiple patterns
+requires <a href=http://landley.net/hg/aboriginal/rev/1692>a patch
+to musl's regex engine</a>, which applies to 1.1.4 but not to the current
+musl source control.)</p>
+
+<p>More portability.h fixes for uClibc too. (I don't expect that to ever have
+another release, so locally patching around posix-2008 violations is silly).</p>
+
+<p><b>Change to username filtering</b></p>
+
+<p>Posix recommends the username creation logic filter usernames to a small
+allowed set of characters (which even Red Hat breaks by explicitly allowing
+"$" at the end), but this prevents UTF-8 usernames. Posix' stated logic
+is to allow filesystems to create the user's home directory, but Linux
+filesystems can accept any character but NUL and "/". The only characters
+we actually _need_ to filter out are ":" (field separator in passwd),
+newline (line separator in passwd), and "/" (directory separator in
+filesystem).</p>
+
+<h3>Documentation</h3>
+
+<p>Web pages updated: cleanup.html documents more cleanup, code.html
+documents more code, and about.html now capitalizes "toybox" consistently
+(it's just a word, capitalize at start of sentence).</p>
+
+<p>The pending/README file now lists commands that needed review/cleanup
+before the pending directory was added.</p>
+
+<h3>Test Suite</h3>
+
+<p>Moved out of scripts/test into top level "tests" directory, and the
+testing.sh script is now in scripts rather than mixed into the *.test files.</p>
+
+<p>Johan Bergström requested VERBOSE=fail to make tests (telling it to
+stop at the first failure), and spotted a build bug where using gnu
+sort on the host broke in non-C locales.</p>
+
+<p>Divya Kothari submitted tests for chmod, link, tar, bzcat, xzcat, zcat,
+and hostname. (And more, but that's all that's merged so far.)</p>

+
+<p><b>New commands</b> added to pending include:
+lsattr, chattr, inotifyd, rfkill, sulogin, strings, makedevs,
+killall5, and tar from Ashwini Sharma, arp from Kyungwan Han,
+sysctl by Bilal Qureshi, partprobe from Bertold Van den Bergh,
+host from Rich felker, and I did nbd-client and the first 2/3 of mount.</p>
+
+<p>Finished cleanups (commands promoted out of pending):
+sysctl, rfkill, strings, mkpasswd, makedevs, partprobe, killall5,
+fallocate, and nbd-client.</p>
+
+<p>(Along the way partial cleanups got made to: last, fold, lspci, ps,
+bootchartd, init, fsck, telnetd, telnet, vconfig, toysh, iconv, useradd,
+login, host, openvt, deallocvt, getty, tftpd, and modprobe. But there's
+still more to do on all of those.)</p>
+
+<p>This time around the <a href=bin>static binaries</a> are linked against
+musl instead of uClibc. (That's why there's no sparc version, musl doesn't
+support that target yet.)</p>
+
+<p><b>Documentation:</b></p>
+
+<p>The help text parser expects lower case "usage:" lines with
+a blank line after them, so go through and regularize those. Expand the
+"coding style" section in the docs and move it to design.html. (Not a show
+stopper for incoming
+contributions, just an explanation of some of the things I'll do to them
+during cleanup.) The help text for the "toybox" command now includes
+the shell script snippet to install symlinks to the toybox binary.</p>
+
+<p>The <a href=cleanup.html>cleanup page</a> now has descriptions for the
+full ifconfig cleanup series, among others.</p>
+
+<p>The new toys/examples directory contains hello.c and skeleton.c. The first is
+a simple hello world program in toybox style, the second is a much more
+elaborate example program using showing how to use the command line option
+parsing and how to provide multiple commands in the same C file.</p>
+
+<p><b>Fixes</b>:</p>
+
+<p>Fix od bug reported by Samuel Holland ("od -v -b" was appending the default
+output type even though an output type was specified). Ashwini Sharma reported
+bugs where readfile() was incorrectly freeing its buffer, and where toy_init()
+was zeroing the wrong data because the field it was using to measure (rebound)
+had moved (when I moved it back I added a comment why the field needs to be
+there), fixed a segfault in the dhcp client, and made a 0 length read at
+the start of password entry count as EOF. Make the "we are not root" test
+in the init code show the help text. Posix implies that fflush() can return
+success even when the stream's error bit is set, so call both fflush() and
+ferror() from xprintf().</p>
+
+<p>Isaac Dunham pointed out that bloatcheck couldn't deal with diff
+implementations that only implement "unified diff" format, and that some
+diff implementations can't handle nonseekable input (I.E. reading from
+a pipe). Bugfix so "help -a" works again. Option parsing on nohup now stops
+at first nonoption argument. Fix segfault in "which" if PATH wasn't set,
+which was actually a bug in lib function find_in_path(). Made rm -rf of
+chmod 000 directories actually remove them.</p>
+
+<p>The build now passes the same $CFLAGS to the library probe as the final
+build, because arch linux is so broken it provides different sets of
+libraries for static and dynamic linking.</p>
+
+<p>It turns out sprintf("%.123s", str) is counting characters, not bytes,
+so globally enabling locale support opens stack smashing vulnerabilities.
+So there's a new TOYFLAGS_LOCALE you set in toyflags when you want the
+setup code to setlocale().</p>
+
+<p><b>Upgrades:</b></p>
+
+<p>Isaac Dunham extended cpio to archive unreadable empty files, and I taught it
+to set uid/gid and timestamp when extracting archives. Isaac also
+added tests for cpio, link, and du, added lspci -i, made the pci database
+parsing skip # comment lines, merged logname and whoami into id.</p>
+
+<p>Daniel Verkamp sped up md5sum about 30% with some loop unrolling, making
+it actually smaller in the process. I added -b flags to md5sum and sha1sum
+for "brief" output that's just the hash with no filename. (I'm aware other
+implementations use that for MSDOS "binary" mode, and don't care.)</p>
+
+<p>When building standalone commands (scripts/singleconfig.sh commandname),
+the build now switches on all the sub-options of the command so we get
+a standalone version with all the bells and whistles enabled.</p>
+
+<p>Add -ds flags to date and document +FORMAT escapes. Add the shell NOP
+command ":" as an alias for true (for toysh).</p>
+
+<p>Add uClibc probe for iconv() and fallocate. (The fact it didn't always
+build against uClibc is why fallocate wasn't enabled in defconfig before.)</p>
+
+<p>The umount command now does an losetup -d on the device by default, so
+we don't leak loopback devices. Bugfix to losetup so "losetup /dev/loop0
+filename" actually works again.</p>
+
+<p>Divya Kothari sent in test suite entries for ls, ln, rm, mv, printf, dd,
+and renice. Then a second round for lsattr/chattr, mount, chmod, pgrep/pkill,
+groupadd, groupdel, and useradd. Several of these uncovered bugs, still
+working to fix them.</p>
+
+<p>There are now free() functions for the predefined llist types and a
+dlist_terminate() function to break doubly linked lists. The new
+generic_signal() handler either sets "toys.signal" or writes a byte
+to toys.signalfd with the signal number if signalfd isn't -1 (which it's
+initialized to in toy_init).</p>
+
+<p>The option parsing logic can now detect when a double fits in a long and
+use the more precise type for floating point arguments (the FLOAT macro
+contains the type used). The human_readable() function now just outputs
+decimal kilo/mega/gigabytes (so when du -u says 5.0G it means 5.0 billion
+bytes). The build infrastructure now notices duplicate commands (so if you
+cp toys/pending/command.c toys/other/command.c and forget to delete the
+first one, the build break is now more informative).</p>

+about time too.</p>
+
+<p>The big news is that the build no longer needs python to generate help.h,
+that's now done in C. The help text generation is also collating help text
+from multiple options, merging command line option blocks and usage: lines.
+There's even a new <a href=help.html>help web page</a>.</p>
+
+<p><b>New commands:</b> Ifconfig, cpio, and su were cleaned up the rest of the
+way and promoted out of pending. That saga is mostly explained on the
+<a href=cleanup.html>cleanup page</a>. Vivek Bhagat's freeramdisk,
+Isaac Dunham's fsfreeze, and Felix Janda's iconv are also new.</p>
+
+<p><b>In pending:</b>
+Ashwini Sharma's team submitted tcpsvd, udpsvd, telnet, telnetd, last, more,
+groupdel/delgroup, arping, brctl, ftpget, ftpput, printf, reset, and added
+ipv6 support to traceroute. Kyungwan Han's team submitted modprobe and getty.
+Vivek Bhagat submitted openvt and deacllocvt. Samuel Holland submitted fold.
+I wrote a new inflate (zip/zlib/gzip decompression) implementation in
+compress.c, and still need to do a corresponding deflate (compression-side)
+and plug them into gzip and zip and so on. (Right now it does zcat.)</p>
+
+<p>Several commands (vmstat, login, du, vconfig, mountpoint, free, chroot,
+cut, touch, modinfo, expand) predate the "pending" directory, and are thus
+in other directories but still need cleanup. Of these, vmstat got some
+work this time (which would be much easier other vmstat implementations
+documented what their output actually meant).</p>
+
+<p><b>Upgrades:</b> Ifconfig grew /prefix netmask support (ala 1.2.3.4/24). Grep now has -zZ to
+handle null terminated data, cksum grew -H for hex output. Upgraded od so the
+fields align better when producing multiple output types. Help has -a and -h
+options (all commands, html output).
+Bugfix to blkid building for a 32 bit target. The date command can actually
+set dates now. The O_NOFOLLOW compile time probe didn't work with cross
+compiling, so it's back to an #ifdef test in portability.h. Nathan McSween
+sent in a bugfix to od and a portability fix in the common library code.
+Ashwini Sharma spotted a bug in pidof -o, and added verbose (-v) options
+to mkdir and ln, and suggested killall should have an -s option and
+allow -l to take zero arguments. Ashwini Sharma and Felix Janda upgraded
+tftpd. Fixed dumpleases still using toynet.h after
+that was removed. Corrected killall return code and error reporting.
+Isacc Dunham fixed bugs all over the tree, did cleanup on a bunch of
+pending commands (getty, ftpget, init, openvt, modprobe...), and clarified
+find's help text. Tom Sparrow ran three different static analyzers on
+the code, which resulted in a few cleanups. The peek()/poke() functions
+now use "volatile" to prevent broken compiler "optimizations" to do with
+aliasing.</p>
+
+<p><b>Build stuff:</b> Each FOR_xxxx macro now has a complementary CLEANUP_xxxx macro, so you
+can put multiple commands with different command line options in the same
+.c file, so they can share infrastructure outside of lib. (This let the
+bunzip logic move out of lib into bzcat.c.) See XXX for example.
+i
+<p>The headers #included in toys.h are now grouped by standard, and headers
+not listed in Posix or LSB were moved to portability.h. The old xregcomp.h
+was folded into lib.h because it's posix (and supporting oddball uClibc
+configurations isn't as important as it once was).</p>
+
+<p>Regression tested against Ubuntu 8.04 to fix up bit-rot in defconfig
+build on older systems. (We depend on Posix-2008, but not necessarily
+the absolute latest build environment.)</p>
+
+<p><b>In lib</b>: lib/xwrap.c added xgetpwnam(), xchroot(), and lib/lib.c now has names_to_pid().
+xsetuid() was replaced with xsetuser() which takes a struct passwd
+and sets both gid and uid, mkpathat() got factored out into a library command,
+get_int_value() became atolx_range(), and
+xmsprintf() is now just xmprintf(). The bunzip2 logic moved from lib into
+bzcat.c.</p>
+
+<p><b>Documentation</b>: new <a href=help.html>help page</a> with the

+cleanup.</p>
+
+<p>That said, I haven't nearly kept up with the flood of new commands going
+into pending: Ashwini Sharma's team submitted
+dd, dumpleases, traceroute, top, useradd, groupadd, mkpasswd, tftpd, and
+an fsck wrapper (with no filesystem drivers yet). Isaac Dunham sent in cpio.</p>
+
+<p>Bugfixes: Jeroen van Rijn added a user count to uptime. Elie De Brauwer
+added -e to watch, removed a memory leak, and fixed a terminal size problem.
+William Haddon made xargs call its command line once even with blank input
+(the standard is vague, but builds expect it), and fixed an off by one bug
+where grep didn't malloc enough space with -E (leading to a segfault).
+I fixed a glitch in bunzip2 (same one as went into busybox since they're using
+the code I wrote), in od to fix -t co, -J, and -c options. Add uname -o as a
+synonym for -s. Build fix to never use $CC without prefixing it with
+$CROSS_COMPILE (since $HOSTCC could be different). Anca Emanuel spotted
+a typo in the web page.</p>
+
+<p>The compile-time command line option parsing got rewritten (ported from
+bash to C), which should speed up builds a bit and allow code controlled by
+--longopts to drop out properly when disabled in the configuration. Terminal
+querying got refactored. Patch's -x option is now more informative (a
+debug thing if you're trying to figure out why a patch didn't apply).
+The "toynet.h" file got folded into toys.h since musl supports it and

+test by Felix Janda, lspci by Isaac Dunham, nl, su, and renice by strake (I.E.
+M. Farkas-Dyck), and sysvinit by Kyungwan Han.</p>
+
+<p>Some cleanup work on existing pending commands that aren't
+ready to promote yet: I did a few more rounds on ifconfig
+and Isaac Dunham's did several cleanups to xzcat, Felix Janda cleaned up
+logger and syslogd...</p>
+
+<p>Also some cleanup work on commands that predate the pending directory,
+but weren't quite polished when they went in, most prominently du,
+expand, and touch.</p>
+
+<h3>Infrastructure</h3>
+
+<p>The new scripts/single.sh builds a standalone command without the
+multiplexer, although not all commands can be built that way yet (NEWTOY yes,
+OLDTOY no) and the space savings aren't anything to write home about. (If a
+command needs the option parsing logic at all, it needs all of it.) If
+you're curious, you can do:</p>
+
+<blockquote><pre>
+make defconfig
+make
+mkdir singles
+for i in $(./toybox)
+do
+ echo $i
+ PREFIX=singles/ scripts/single.sh $i || break
+done
+</pre>
+<p>(And then wait a long time and watch almost half the builds fail.)</p>
+</blockquote>
+
+<p>There is now libbuf analogous to toybuf, another global 4k buffer this
+time for use by lib/ code instead of command code.</p>
+
+<p>The lib directory got split up a bit, lib/pending.c contains functions
+not yet used by anything outside of toys/pending/*, and lib/xwrap.c contains
+functions that wrap other functions and handle failures (via error_exit).
+This leaves lib/lib.c containing actual new functions.</p>
+
+<p>General improvements and bug fixes to argument parsing. The [-abc] exclude
+logic should now clear arguments slots when disabling options. Bare --longopts
+should work now and be able to report errors using their name, the new ;
+option allows optional arguments to longopts only suppliable with = (I.E.
+--color and --color=auto but not --color auto).</p>
+
+<p>I'm gradually weaning the code off of itoa()/utoa() because sprintf
+does this already. In this case "simple" probably means "let libc do it
+for us".</p>
+
+<p>Rewrote for_each_pid_with_name_in() and renamed it to just names_to_pid().
+It shouldn't get confused trying to compare absolute and relative paths quite
+so much anymore.</p>
+
+<p>lib/llist.c grew a new dlist_pop() function for removing a doubly
+linked list entry while maintaining a circular list; tail and patch are
+using it now.</p>
+
+<p>The musl guys suggested a new optimization flag
+(-fno-asynchronous-unwind-tables)
+that shaves about 10% off the binary size by removing a C++ism that crept
+into gcc's idea of C. While I don't normally try to micromanage the compiler,
+"-fstop-being-stupid" is a thing you have to hit gcc with from time to time.</p>
+
+<h3>Bugfixes</h3>
+
+<p>Felix Janda and I did a largeish rewrite of tail to
+finally make it work right (we think). Still need to implement tail -f
+someday (the tricky bit is making -f follow multiple files at once).
+Felix also reported a bug in xpidfile.</p>
+
+<p>Juhani Haverinen pointed out that
+python 3 doesn't work with config2help.py, so the detection logic looks
+for python2 (until I get around to rewriting that in C). Elie De Brauwer
+then fixed our first attempt at this, and also fixed uname's help string.</p>
+
+<p>Ashwini Sharma
+pointed out the build was making a FLAG_ macro for " " which broke some
+configurations. (That's a control character, not a command line option.)</p>
+
+<p>Jacek Bukarewicz pointed out a bug in chdir permission handling, and
+a way to make env segfault. Both should be fixed now.</p>
+
+<p>The new function xexec_optargs()
+replaces calls to xexec(toys.optargs) to avoid freeing and reusing optargs
+during option parsing screwing stuff up (such as netcat's exec mode).</p>
+
+<p>The stat command's %a output was padded with leading zeroes, which
+didn't match anybody else's behavior and thus made the test suite hiccup
+between TEST_HOST and testing toybox. (If you go "TEST_HOST=1 scripts/test.sh
+command" it sanity checks the tests against the host implementation.)</p>
+
+<p>Last release, "mkdir sub/sub && chmod 007 sub/sub && rm -rf sub" didn't
+delete sub and didn't exit with an error either. Neither was correct, rm
+should now be fixed.</p>

+
+<p><a href=downloads/toybox-0.4.5.tar.bz2>Toybox 0.4.5</a> is based on
+<a href=http://landley.net/hg/toybox/shortlog/941>commit 941</a>. It adds
+uuencode and uudecode from Erich Plondke, and enables Luis Morales' "who" by
+default. Felix Janda and I cleaned up last year's "stat" submission and
+enabled it. Ivo van Poorten added "groups".
+Andre Renaud added "lsusb". I implemented "split", "pivot_root", and "mv".
+</p>
+
+<p>The "help" command is implemented differently now (lib/help.c) and
+each command can now understand --help (including both "toybox --help"
+and "toybox --help command" in the multiplexer).</p>
+
+<p>The "pending" directory has several commands (find, xzcat, nbd-client,
+logger, expr) which work but are not enabled by default pending further cleanup.
+Ifconfig is enabled, but still in pending because it's only 2/3 cleaned up.
+(It's an awkward halfway state but I'm not holding up the release for it.)</p>
+
+<p>I'm <a href=cleanup.html>documenting the cleanups</a> to teach
+more people to do it, but the writeups aren't caught up yet. The
+<a href=roadmap.html>roadmap</a> also got updated a bit with further analysis
+of other projects, and the README and about pages got updated.</p>
+
+<p>Fixed _another_ "ls -C" segfault when terminal size can't be detected,
+condensed the ls help text to fit on one page, implented --color, and taught
+-l to print the major, minor numbers when showing block/char devices.
+Argument parsing now handles "--" properly (to end option checking),
+and the infrastructure can now handle bare --longopts that have no
+corresponding short option (both were implemented before but didn't work).
+Fixed an old bug in "patch", chmod grew -f, who grew -a. Isaac Dunham
+fixed "-" vs "_" handling in modinfo, added a "firmware" output
+field, added -b and -k support, and taught it that the ".ko" extension means
+to look for the file at the specified path instead of under /lib. Felix Janda
+moved file permission display code to lib so ls and
+stat could share it. Ashwini Sharma spotted a bug in xabspath when the
+last path component exists but we haven't got permissions to open it
+(ala readlink -f /dev/sda as a normal user).
+</p>
+
+<p>In the build infrastructure, scripts/findglobals.sh finds leaked global
+variables. (Leaked means they aren't part of the global union: Other than glibc
+debris, toybox should define "this", "toy_list", "toybuf", and "toys", and
+that's it; the rest add memory footprint to every command for the benefit of
+just one command; use GLOBALS() to stick 'em in the union.) Static linking
+against libraries other than the host's libc now applies to feature probes
+for unshare and such. Neuter stupid internationalization support that makes
+various host "sort" commands put things in an order other than alphabetical
+(breaking the multiplexer's binary search on command names).
+
+<p>You should now be able to build from a source control snapshot on a build
+system that hasn't got python: if you disable CONFIG_TOYBOX_HELP. (The
+release tarballs ship generated/help.h, but it's not in source control.
+Eventually I should rewrite that python script in C.)</p>

+are now exactly 100 commands in defconfig (of a little over 220 on the
+<a href=roadmap.html>todo list</a>).</p>
+
+<p>Elie De Brauwer added the rev command, cleaned up tac, implemented the -s
+and -f flags for seq, added -v and -i to killall (and fixed killall not to
+kill itself before finishing its pid list), and added to the test suite.
+Felix Janda added -m to mkdir, pwd -L and -P, and more test suite entries.</p>
+
+<p>Rob Landley added the losetup command, and fixed the existing ls, cp, and
+readlink commands. The segfault in ls
+happened when it couldn't determine the screen size (last release changed the
+default to -C and a screen size of 0 made column view unhappy), and cp got an
+extensive rewrite bringing it up to date with the dirtree changes and fixing
+a number of things it never did right in the first place. The xabspath()
+code in the library now handles a symlink after ".." properly (and the test
+suite checks for it).</p>
+
+<p>Infrastructure-wise the code is better about automatically setting the
+error return code properly. Now error_msg() sets the exit code to 1 if it's
+still defaulting to 0, and the global exit path does a fflush(NULL) with error
+bit check rather than trying to be quite so granular about flushing. (That
+means if we use printf() instead of xprintf() it still exits with the right
+error code, it just doesn't end the program early on an output error.)
+Minor bugfix so TOYBOX_DEBUG
+doesn't always warn about the lack of suid bit when toybox is built with
+at least one STAYROOT command. Bugfix for the option [grouping] logic
+(and then further fixes to the error reporting pointed out by Ashwini Sharma).
+dirtree_handle_callback() now has a prefix like the rest of the dirtree
+functions. A lot of stuff doing manual path handling was switched to using
+libc basename() (including, embarassingly, the basename command), which means
+it now correctly detects "/trailing/slash/" which the previous code didn't.</p>
+
+<p>Also, last release included some accidentally checked in debug code that
+disabled compiler optimization, so the binary size bloated a bit. It's back
+to -Os by default now.</p>

+just a resync. Linux 3.7 came out, meaning it's time to do an Aboriginal
+Linux release, and that should use a stable version of toybox. So here's
+a new stable version.</p>
+
+<p>The new commands are cut (from Jason Kyungwan Han), touch
+(from Choubey Ji), expand (from Jonathan Clairembault, and he fixed a
+bug in login), and rm (from Rob Landley). Felix Janda added UTF-8
+support infrastructure (for non-ascii character sets) with a config option.
+Elie De Brauwer added tests for cat and sha1sum, and -so options to pidof.
+The "ls" command defaults to -C (column view) now, and "readlink" now supports
+-fenq.</p>
+
+<p>Portability work: toybox should now build against the musl C library,
+and against older glibc versions (circa 2008, much before that and kernel
+features we depend on start to drop out).</p>
+
+<p>The whole codebase got reindented from "one tab" to "two spaces" per
+level. The option parsing logic now understands [groups] of commands (when more
+than one in a group is selected it can switch the others off, or error out,
+or other things). The error_exit() infrastructure can now longjmp back to an
+earlier point instead of exiting. Each toys/* directory now has a README,
+the first line of which is the fancy name menuconfig uses for the directory
+(so no more hardwired directory list in scripts/genconfig.sh).</p>
+
+<p>Fixed a filehandle leak in getmountlist().
+Pass parent pointer to dirtree_add_node() so it can give error messages with
+full path. The yesno() function now always reads from stdin and writes to
+stderr (we can retry tty checking complexity once we've got commands needing
+it).</p>
+
+<p>The open group broke their website so the
+<a href=http://opengroup.org/onlinepubs/9699919799>old links</a> to POSIX 2008
+now <a href=http://pubs.opengroup.org/onlinepubs/9699919799>need to start with
+pubs</a>. Some of the links in the tree have been updated, others haven't while
+I wait to see if their webmaster notices and fixes it.</p>
+
+<p>(I note that the current rm implementation is not technically posix compliant
+because the standard requires infinite recursion depth and the current
+implementation uses one filehandle per level. I can add a config option
+to do it Posix's way, which is more brittle and needs extra security checks,
+but am waiting for somebody to complain first. The default "ulimit -n" is 1024
+filehandles, so drilling down over 1000 nested subdirectories).</p>

+Felix Janda added -m support to wc (for utf8).</p>
+
+<p>On the infrastructure side, the commands have now been grouped into

+
+<p>Bugfixes: Avery Pennarun spotted a case where ls showed uid twice instead of
+uid and gid, and that nice was using the wrong range of numbers.
+The ls command also recursed inappropriately last time (not quite
+properly converted for the dirtree changes last release), and now it's
+fixed. Roy Tam pointed out a glitch in sh, and fixed df's percentage
+calculation to match the POSIX spec. The kernel build didn't like our mktemp
+and it does now. The wc command wasn't quite posix compliant (trailing spaces
+break stuff). The ls command recursed inappropriately last time (not quite
+properly converted for the dirtree changes last release), and now it's
+fixed. The catv command wasn't displaying byte 255 correctly. Some lib
+fixes (thinko in xpidfile). Fixed uname -m when running a 32 bit x86 binary
+on an x86-64 host (it lies and says the system is i686, i586, or i486 depending
+on what the toolchain that built the binary supported. This makes builds in
+a 32 bit chroot on a 64 bit kernel break less.) The df command was checking
+partitions in the wrong order (displaying undermounts instead of overmounts:
+this used to work but some library code changed out from under it and it
+wasn't updated to match until now). Felix Janda filled out the test suite
+some more. The patch file creation logic got tweaked several times to
+successfully apply more patches. Support for older (pre 2.10) glibc
+versions was added to portability.h.</p>
+
+<p>Miscelaneous cleanups all around (mknod, sha1sum, logname), including a

+wheel, New York, wars and so on - whilst all the dolphins had ever done was
+muck about in the water having a good time. But conversely, the dolphins had
+always believed that they were far more intelligent than man - for precisely
+the same reasons." - The Hitchhiker's Guide to the Galaxy.</p></blockquote>
+
+<p>It's well past time for <a href=downloads/toybox-0.3.0.tar.bz2>toybox 0.3.0</a>,
+so here it is, based
+on <a href=http://landley.net/hg/toybox/shortlog/595>commit 595</a>, and the
+statically linked <a href=downloads/binaries>prebuilt binaries</a> should
+actually be statically linked this time (thanks Ashwini Sharma for spotting
+that).</p>
+
+<p>It's hard to figure out where to cut a release, because development
+doesn't stop. "Long before now" is the obviuos answer, of course.
+The project's maintainer also moved house during this development cycle, which
+threw things off for a bit (so many boxes). Releases should hopefully be a bit
+more frequent from here on.</p>
+
+<p>The big things Rob worked on this time were the new dirtree (directory
+tree traversal) infrastructure, and a complete rewrite of ls using that
+which should now implement all 26 posix options.</p>
+
+<p>Georgi Chorbadzhiyski added printenv, whoami, mkdir, mkfifo, chmod, chown,
+chgrp, and uniq. He also added fraction and extension support to sleep (so if
+you need a quarter-second sleep, it can do that now), and fixed a build bug
+on slackware.</p>
+
+<p>Daniel Walter contributed a string to mode_t parser (in use by chmod and
+mkdir -m). Ilya Kuzmich contributed comm. Elie De Brauwer added mountpoint,
+vmstat, logname, login, and mktemp. Kevin Chase did some portability cleanups.
+Pere Orga fixed some documentation.</p>
+
+<p>The "tac" and "clear" commands are now normal commands instead of shell
+wrappers, and the header #includes have been cleaned up a bit to remove
+deprecated functions and attempt to increase compatability with the bionic and
+musl C libraries, "tail" should now use lseek() for large files, and "id" got
+some cleanups and bugfixes.</p>
+
+<p>The new TOYBOX_FLOAT configuration option selects whether or not
+to include floating point support (for embedded targets where that's
+problematic).</p>
+
+<p>Several random bugfixes: unshare() might actually build portably now,
+yes 'n' | cp -i should no longer bypass stdin and prompt via the tty, the
+SUID support no longer drops permissions going through the toybox
+multiplexer command, and a bugfix to xargs -0 means it should no longer
+segfault. (I have a pending bug report about xargs not doing the full
+posix whitespace handling that -0 obsoleted, but I'll deal with that next
+release.)</p>
+
+<p>The build infrastructure is now automatically generating FLAG_ macros
+for the options, but currently with the wrong names. Some more macro glue
+is necessary, which I haven't quite figured out how to do yet.</p>
+
+<p>A defconfig toybox at the start of the $PATH has successfully built
+Linux From Scratch (in my Aboriginal Linux project). The commands that
+'default n' in the config are often still broken, cleanup is ongoing.
+(The new dirtree stuff broke several of them that haven't been converted
+yet, but if I wait until everything works we won't have a release before
+1.0, so here's a checkpoint.)</p>

+
+<p>It's been a busy few weeks, almost entirely due to new contributors. (I
+have not quite been keeping up.)</p>
+
+<p>Elie De Brauwer contributed free, uptime, swapon, swapoff, lsmod, mknod,

+Walter wrote kill and extended id. Timothy Elliott contributed tail and tests
+for cmp. Frank Bergmann sent a warning fix. Bryce Fricke added -i to cp.
+Nathan McSween pointed out an optimization. Georgi Chorbadzhiyski fixed
+cross compiling to work more reliably.</p>
+
+<p>(My own contribution this time around was just tightening up other people's
+code, a build fix to unshare, some random bugfixes, and so on. My only new
+code this time around was writing a bash replacement for the existing python
+bloat-o-meter.)</p>
+
+<p>Last time (the 0.2.0 release) included the first pass at an id command from
+Tim Bird, env and basename from Tryn Mirell, cmp and head from Timothy Elliott,
+more bugfixes from Nathan McSween and Elie De Brauwer, and Luis Felipe Strano
+Moraes did a first pass at the who command plus other bugfixes and
+optimizations.</p>
+
+<p>(For that release I did xargs, cal, truncate, unlink, nohup, tty, wc, link,

+<h2>Old News</h2>
+
+<p>This project <a href=http://lists.busybox.net/pipermail/busybox/2006-September/024794.html>started in 2006</a>, got mothballed in 2009
+<a href=http://landley.net/notes-2009.html#18-06-2009>for</a>
+<a href=http://landley.net/notes-2011.html#31-03-2011>various</a>
+<a href=http://landley.net/notes-2011.html#08-06-2011>reasons</a>
+(during which time I
+<a href=http://lists.busybox.net/pipermail/busybox/2010-March/071783.html>contributed</a>
+some toybox code and design ideas to busybox</a> but retained the copyrights to
+my work), then <a href=http://landley.net/notes-2011.html#13-11-2011>relaunched</a>
+under a 2-clause BSD license in 2011.
+The following news entries predate that relaunch:</p>
+
+<hr>
+<p><b>December 1, 2009</b> - <a href=downloads/toybox-0.1.0.tar.bz2>toybox-0.1.0</a> is out.</p>
+
+<p>This release is a couple build fixes and another bugfix to patch.</p>
+
+<hr>
+<p><b>April 17, 2009</b> - Another bugfix release,
+<a href=downloads/toybox-0.0.9.2.tar.bz2>toybox-0.0.9.2</a>, off by one allocation error in patch.</p>
+
+<p>(Darn fiddly command, innit?)</p>
+
+<hr>
+<p><b>March 29, 2009</b> - Released
+<a href=downloads/toybox-0.0.9.1.tar.bz2>toybox 0.0.9.1</a> which is a bugfix
+release for issues with the patch command.</p>
+
+<p>The project is currently on hold while the developers learn Lua and
+decide whether or not to port the whole thing to that language.
+(Also note: the mailing list moved. See the links on the left. You'll
+have to resubscribe.)</p>
+
+<hr>
+<p><b>January 29, 2009</b> - Released
+<a href=downloads/toybox-0.0.9.tar.bz2>toybox 0.0.9.tar.bz2</a> which is a minor packaging
+fix for 0.0.8. (The previous release tarball contained a prebuilt x86-64
+kconfig/conf file, because the release script ran defconfig to
+pregenerate help.h, and didn't run make clean afterwards.) The actual source
+code is identical to the previous release.</p>
+
+<hr>
+<p><b>January 20, 2009</b> - <a href=downloads/toybox-0.0.8.tar.bz2>toybox 0.0.8</a>
+adds the uname, cksum, and mkswapfs commands.</p>
+
+<p>This uname implementation is cross compile friendly: when built as a 32 bit
+binary on an x86_64 host, it reports "i686" to confuse autoconf less.</p>
+
+<p>This cksum has several extra command line options which can be used to
+produce different cksum variants based on the same crc32 algorithm. For
+example, the broadcom "trx" image packaging uses a little endian crc,
+pre-inverted instead of post-inverted, and does not include the length.
+(Without these arguments, it produces the normal SUSv4 cksum output.)</p>
+
+<p>It also upgrades netcat with a server mode (-l option) and fixes several
+netcat bugs. It also fixed multiple bugs in "patch", works around a
+reiserfs bug in cp, and oneit can reboot on exit more reliably.</p>
+
+<p><b>November 12, 2008</b> -
+<a href=downloads/toybox-0.0.7.tar.bz2>toybox 0.0.7</a>
+adds sort and tee commands, upgrades the internal option parsing logic and the
+test suite, and numerous bugfixes (bunzip, chroot, cat, patch).</p>
+
+<p><b>May 26, 2008</b> - <a href=downloads/toybox-0.0.6.tar.bz2>toybox 0.0.6</a>
+adds cat, rmdir, and seq. Bugfixes to cp and a new -v option. Updates mdev to
+work with the 2.6.25 kernel. Updates patch to knows that a file dated
+1969-12-31 means it doesn't exist, and to fail if a file it needs to create
+already exists. Command line option parsing can now handle things like "echo
+-nex" vs "echo -ne". Several updates to the test suite (run scripts/test.sh),
+and some build fixes.</p>
+
+<p>
+<hr>
+<p><b>March 29, 2008</b> -
+Time to release <a href=downloads/toybox-0.0.5.tar.bz2>toybox 0.0.5</a>, with
+new commands cp and chvt and several bugfixes.</p>
+
+<p>More makefile targets: "make test" runs the test suite (which needs more test
+scripts), and make install/install_flat/uninstall/uninstall_flat calls
+make/install.sh (with options --long --symlink --force --uninstall depending
+on the context).</p>
+
+<p>Most of the work has been behind the scenes, namely a significant rewrite of
+the build logic so adding each new command consists of adding a single C file to
+the "toys" directory, eliminating the need to touch any other files.
+There are specially formatted comments at the top of the C file to generate
+the other files, see toys/hello.c for an example. (See generated/README.txt
+and <a href=code.html>code.html</a> for details.)</p>
+
+<p><b>January 2, 2008</b> - And <a href=downloads/toybox-0.0.4.tar.bz2>toybox-0.0.4.tar.bz2</a> is out.
+The new applets this time around include basename, chroot, dirname, dmesg,
+help, mkfifo, netcat, patch, sha1sum, touch, and tty.</p>
+
+<p>Note that this "touch" includes -l to set the length, which can truncate
+a file or create a commpletely sparse file, good for filesystem images.</p>
+
+<p>Expect the next release in about 6 months.</p>
+
+<p><b>December 12, 2007</b> - Updated the list of implemented applications,
+put up a <a href=todo.txt>todo list</a> and <a href=code.html>infrastructure
+documentation</a>. Expect another release towards the end of the month.</p>
+
+<p><b>June 18, 2007</b> - Put out
+<a href=downloads/toybox-0.0.3.tar.bz2>toybox-0.0.3.tar.bz2</a> since it's
+been too long since I did something like that. This one implements
+catv, count, df, echo, false, oneit, pwd, sleep, sync, toysh, true, which,
+and yes (which is what "make defconfig" enables). There are several other
+commands not enabled by defconfig, because they don't really work yet.</p>
+
+<p>Most of the general infrastructure's there now, although lots of tweaking
+and optimizing is still needed. The test suite is skeletal and not entirely
+checked in yet, but I'm working on that.</p>
+
+<p>I don't have nearly as much time to work on this as I'd like, but I'm making
+a little progress.</p>
+
+<p><b>January 31, 2007</b> -
+Toybox <a href=downloads/toybox-0.0.2.tar.bz2>0.0.2 release</a>.
+Implements count, yes, pwd, echo, bzcat, catv, oneit, and an unfinished
+skeleton of mke2fs. Adds argument parsing logic and bunzip code to library.
+Now configured with menuconfig. Adds "make baseline" and "make bloatcheck"
+using Matt Mackall's bloat-o-meter, and scripts/showasm.</p>
+
+<p>Screwing up the web page a bit, adding an index bar along the side
+which doesn't properly connect up to anything yet. (Busy implementing
+mke2fs and gene2fs.)</p>
+
+<p><b>October 30, 2006</b> -
+Toybox <a href=downloads/toybox-0.0.1.tar.bz2>0.0.1 release</a>. Implements
+df, a skeletal toysh, and some library functions. Proof of concept, really.</p>
+
+<p><b>September 7, 2006</b> -
+Project launched, first commit to mercurial archive.</p>

+<title>Toybox Roadmap</title>
+
+<h2>Goals and use cases</h2>
+
+<p>We have several potential use cases for a new set of command line
+utilities, and are using those to determine which commands to implement
+for Toybox's 1.0 release.</p>
+
+<p>The most interesting standards are POSIX-2008 (also known as the Single
+Unix Specification version 4) and the Linux Standard Base (version 4.1).
+The main test harness including toybox in Aboriginal Linux and if that can
+build itself using the result to build Linux From Scratch (version 6.8).
+We also aim to replace Android's Toolbox.</p>
+
+<p>At a secondary level we'd like to meet other use cases. We've analyzed
+the commands provided by similar projects (klibc, sash, sbase, s6, embutils,
+nash, and beastiebox), along with various vendor configurations of busybox,
+and some end user requests.</p>
+
+<p>Finally, we'd like to provide a good replacement for the Bash shell,
+which was the first program Linux ever ran and remains the standard shell
+of Linux no matter what Ubuntu says. This doesn't mean including the full
+set of Bash 4.x functionality, but does involve {various,features} beyond
+posix.</p>
+
+<p>See the <a href=status.html>status page</a> for the combined list
+and progress towards implementing it.</p>

+<h2>Use case: standards compliance.</h2>
+
+<h3><a name=susv4 /><a href="#susv4">POSIX-2008/SUSv4</a></h3>
+<p>The best standards are the kind that describe reality, rather than
+attempting to impose a new one. (I.E. a good standard should document, not
+legislate.)</p>
+
+<p>The kind of standards which describe existing reality tend to be approved by
+more than one standards body, such ANSI and ISO both approving C. That's why
+the IEEE POSIX committee's 2008 standard, the Single Unix Specification version
+4, and the Open Group Base Specification edition 7 are all the same standard
+from three sources.</p>
+
+<p>The <a href="http://pubs.opengroup.org/onlinepubs/9699919799/idx/utilities.html">"utilities"
+section</a>
+of these standards is devoted to the unix command line, and are the best such
+standard for our purposes. (My earlier work on BusyBox was implemented with
+regard to SUSv3, an earlier version of this standard.)</p>
+
+<h3>Problems with the standard</h3>
+
+<p>Unfortunately, these standards describe a subset of reality, lacking any
+mention of commands such as init, login, or mount required to actually boot a
+system. It provides ipcrm and ipcs, but not ipcmk, so you can use System V IPC
+resources but not create them.</p>
+
+<p>These standards also contain a large number of commands that are
+inappropriate for toybox to implement in its 1.0 release. (Perhaps some of
+these could be reintroduced in later releases, but not now.)</p>
+
+<p>Starting with the full "utilities" list, we first remove generally obsolete
+commands (compess ed ex pr uncompress uccp uustat uux), commands for the
+pre-CVS "SCCS" source control system (admin delta get prs rmdel sact sccs unget
+val what), fortran support (asa fort77), and batch processing support (batch
+qalter qdel qhold qmove qmsg qrerun qrls qselect qsig qstat qsub).</p>
+
+<p>Some commands are for a compiler toolchain (ar c99 cflow ctags cxref gencat
+iconv lex m4 make nm strings strip tsort yacc), which is outside of toybox's
+mandate and should be supplied externally. (Again, some of these may be
+revisited later, but not for toybox 1.0.)</p>
+
+<p>Some commands are part of a command shell, and cannot be implemented as
+separate executables (alias bg cd command fc fg getopts hash jobs kill read
+type ulimit umask unalias wait). These may be revisited as part of a built-in
+toybox shell, but are not exported into $PATH via symlinks. (If you fork a
+child process and have it "cd" then exit, you've accomplished nothing.
+This is not a complete list, a shell also needs exit, if, while, for, case,
+export, set, unset, trap, exec... And for bash compatability, function and
+source.)</p>
+
+<blockquote><b>
+<span id=shell>
+alias bg cd command fc fg getopts hash jobs kill read type ulimit umask
+unalias wait exit if while for case export set unset trap exec function source
+</span>
+</b></blockquote>
+
+<p>A few other commands are judgement calls, providing command-line
+internationalization support (iconv locale localedef), System V inter-process
+communication (ipcrm ipcs), and cross-tty communication from the minicomputer
+days (talk mesg write). The "pax" utility was supplanted by tar, "mailx" is
+a command line email client, and "lp" submits files for printing to... what
+exactly? (cups?) The standard defines crontab but not crond.</p>
+
+<p>Removing all of that leaves the following commands, which toybox should
+implement:</p>
+
+<blockquote><b>
+<span id=posix>
+at awk basename bc cal cat chgrp chmod chown cksum cmp comm cp
+csplit cut date dd df diff dirname du echo env expand expr false file find
+fold fuser getconf grep head id join kill link ln logger logname ls man
+mkdir mkfifo more mv newgrp nice nl nohup od paste patch pathchk printf ps
+pwd renice rm rmdir sed sh sleep sort split stty tabs tail tee test time
+touch tput tr true tty uname unexpand uniq unlink uudecode uuencode vi wc
+who xargs zcat
+</span>
+</b></blockquote>
+
+<h3><a name=sigh /><a href="#sigh">Linux Standard Base</a></h3>
+
+<p>One attempt to supplement POSIX towards an actual usable system was the
+Linux Standard Base. Unfortunately, the quality of this "standard" is
+fairly low.</p>
+
+<p>POSIX allowed its standards process to be compromised
+by leaving things out, thus allowing IBM mainframes and Windows NT to drive
+a truck through the holes and declare themselves compilant. But it means what
+they DID standardize tends to be respected (if sometimes obsolete).</p>
+
+<p>The Linux Standard Base's failure mode is different, they respond to
+pressure by including special-case crap, such as allowing Red Hat to shoehorn
+RPM into the standard even though all sorts of distros (Debian, Slackware, Arch,
+Gentoo) don't use it and probably never will. This means anything in the LSB is
+at best a suggestion: arbitrary portions of this standard are widely
+ignored.</p>
+
+<p>The community perception seems to be that the Linux Standard Base is
+the best standard money can buy, I.E. the Linux Foundation is supported by
+financial donations form large companies and the LSB represents the interests
+of those donors more than technical merit. Debian officially
+<a href=http://lwn.net/Articles/658809>washed its hands of LSB</a> when 5.0
+came out in 2015, and no longer even pretends to support it (which may affect
+Debian derivatives like Ubuntu and Knoppix). Toybox hasn't moved to 5.0 for
+similar reasons.</p>
+
+<p>That said, Posix by itself isn't enough, and this is the next most
+comprehensive standards effort for Linux so far.</p>
+
+<p>The LSB specifies a <a href=http://refspecs.linuxfoundation.org/LSB_4.1.0/LSB-Core-generic/LSB-Core-generic/cmdbehav.html>list of command line
+utilities</a>:</p>
+
+<blockquote><b>
+ar at awk batch bc chfn chsh col cpio crontab df dmesg du echo egrep
+fgrep file fuser gettext grep groupadd groupdel groupmod groups
+gunzip gzip hostname install install_initd ipcrm ipcs killall lpr ls
+lsb_release m4 md5sum mknod mktemp more mount msgfmt newgrp od passwd
+patch pidof remove_initd renice sed sendmail seq sh shutdown su sync
+tar umount useradd userdel usermod xargs zcat
+</b></blockquote>
+
+<p>Where posix specifies one of those commands, LSB's deltas tend to be
+accomodations for broken tool versions which aren't up to date with the
+standard yet. (See <a href=http://refspecs.linuxfoundation.org/LSB_4.1.0/LSB-Core-generic/LSB-Core-generic/more.html>more</a> and <a href=http://refspecs.linuxfoundation.org/LSB_4.1.0/LSB-Core-generic/LSB-Core-generic/xargs.html>xargs</a>
+for examples.)</p>
+
+<p>Since we've already committed to using our own judgement to skip bits of
+POSIX, and LSB's "judgement" in this regard is purely bug workarounds to declare
+various legacy tool implementations "compliant", this means we're mostly
+interested in the set of tools that aren't specified in posix at all.</p>
+
+<p>Of these, gettext and msgfmt are internationalization, install_initd and
+remove_initd aren't present on ubuntu 10.04, lpr is out of scope, and
+lsb_release is a distro issue (it's a nice command, but the output of
+lsb_release -a is the name and version number of the linux distro you're
+running, which toybox doesn't know).</p>
+
+<p>This leaves:</p>
+
+<blockquote><b>
+<span id=lsb>
+chfn chsh dmesg egrep fgrep groupadd groupdel groupmod groups
+gunzip gzip hostname install killall md5sum
+mknod mktemp mount passwd pidof sendmail seq shutdown
+su sync tar umount useradd userdel usermod zcat
+</span>
+</b></blockquote>

+<h2><a href="#dev_env">Use case: provide a self-hosting development environment</a></h2>
+
+<p>The following commands are enough to build the <a href=http://landley.net/aboriginal/about.html>Aboriginal Linux</a> development
+environment, boot it to a shell prompt, and build <a href=http://www.linuxfromscratch.org/lfs/view/6.8/>Linux From Scratch 6.8</a> under
+it. (Aboriginal Linux <a href=http://landley.net/aboriginal/history.html>currently uses</a> BusyBox for this, thus providing a
+drop-in test environment for toybox. We install both implementations side
+by side, redirecting the symlinks a command at a time until the older
+package is no longer used, and can be removed.)</p>
+
+<p>This use case includes running init scripts and other shell scripts, running
+configure, make, and install in each package, and providing basic command line

+<h2><a name=android /><a href="#android">Use case: Replacing Android Toolbox</a></h2>
+
+<p>Android has a policy against GPL in userspace, so even though BusyBox
+predates Android by many years, they couldn't use it. Instead they grabbed
+an old version of ash and implemented their own command line utility set
+called "toolbox". ash was later replaced by
+<a href="https://www.mirbsd.org/mksh.htm">mksh</a>; toolbox is being
+replaced by toybox.</p>
+
+<p>Toolbox doesn't have its own repository, instead it's part of Android's
+<a href=https://android.googlesource.com/platform/system/core>system/core
+git repository</a>.</p>
+
+<h3>Toolbox commands:</h3>
+
+<p>According to <a href=https://android.googlesource.com/platform/system/core/+/master/toolbox/Android.mk>
+system/core/toolbox/Android.mk</a> the toolbox directory builds the
+following commands:</p>
+
+<blockquote><b>
+dd getevent newfs_msdos
+</b></blockquote>
+
+<p>The toolbox makefile also builds the BSD grep right now, because toybox
+grep is missing <code>--color</code>.</p>
+
+<h3>Other Android core commands</h3>
+
+<p>Other than the toolbox directory, the currently interesting
+subdirectories in the core repository are init,
+logcat, logwrapper, reboot, and run-as.</p>
+
+<ul>
+<li><b>init</b> - Android's PID 1</li>
+<li><b>logcat</b> - read android log format</li>
+<li><b>logwrapper</b> - redirect stdio to android log</li>
+<li><b>reboot</b> - Android's reboot(1)</li>
+<li><b>run-as</b> - subset of sudo</li>
+</ul>
+
+<p>Almost all of these reinvent an existing wheel with less functionality and a
+different user interface. We may want to provide that interface, but
+implementing the full commands (fdisk, init, and sudo) come first.</p>
+
+<h3>Analysis</h3>
+
+<p>For reference, combining everything listed above, we get:</p>
+
+<blockquote><b>
+dd getevent init
+logcat logwrapper
+newfs_msdos reboot run-as
+</b></blockquote>
+
+<p>We may eventually implement all of that, but for toybox 1.0 we need to
+focus a bit. For our first pass, let's grab just logcat and logwrapper
+from the "core" commands (since the rest have some full/standard version
+providing that functionality, which we can implement a shim interface
+for later).</p>
+
+<p>This means toybox should implement (or finish implementing):</p>
+<blockquote><b>
+<span id=toolbox>
+dd getevent logcat logwrapper newfs_msdos
+</span>
+</b></blockquote>
+
+<p>Update: Android.mk is currently building the following toybox files out
+of "pending". These should be a priority for cleanup:</p>
+
+<blockquote><b>
+dd expr lsof more tar tr traceroute
+</b></blockquote>

+<p>They have a fairly long list of new commands they'd like to see in toybox:</p>
+

+<hr /><a name=klibc />
+<h2>klibc:</h2>
+
+<p>Long ago some kernel developers came up with a project called
+<a href=http://en.wikipedia.org/wiki/Klibc>klibc</a>.
+After a decade of development it still has no web page or HOWTO,
+and nobody's quite sure if the license is BSD or GPL. It inexplicably
+<a href=http://www.infoworld.com/d/data-center/perl-isnt-going-anywhere-better-or-worse-211580>requires perl to build</a>, and seems like an ideal candidate for
+replacement.</p>
+
+<p>In addition to a C library even less capable than bionic (obsoleted by
+musl), klibc builds a random assortment of executables to run init scripts
+with. There's no multiplexer command, these are individual executables:</p>
+
+<blockquote><p><b>
+cat chroot cpio dd dmesg false fixdep fstype gunzip gzip halt ipconfig kill
+kinit ln losetup ls minips mkdir mkfifo mknodes
+mksyntax mount mv nfsmount nuke pivot_root poweroff readlink reboot resume
+run-init sh sha1hash sleep sync true umount uname zcat
+</b></p></blockquote>
+
+<p>To get that list, build klibc according to the instructions (I
+<a href=http://landley.net/notes-2013.html#23-01-2013>looked at</a> version
+2.0.2 and did cd klibc-*; ln -s /output/of/kernel/make/headers_install
+linux; make) then <b>echo $(for i in $(find . -type f); do file $i | grep -q
+executable && basename $i; done | grep -v '[.]g$' | sort -u)</b> to find
+executables, then eliminate the *.so files and *.shared duplicates.</p>
+
+<p>Some of those binaries are build-time tools that don't get installed,
+which removes mknodes, mksyntax, sha1hash, and fixdep from the list.
+(And sha1hash is just an unpolished sha1sum anyway.)</p>
+
+<p>The run-init command is more commonly called switch_root, nuke is just
+"rm -rf -- $@", and minips is more commonly called "ps". I'm not doing aliases
+for the oddball names.</p>
+
+<p>Yet more stale forks of dash and gzip sucked in here (see "dubious
+license terms" above), adding nothing to the other projects we've looked at.
+But we still need sh, gunzip, gzip, and zcat to replace this package.</p>
+
+<p>At the time I did the initial analysis toybox already had cat, chroot, dmesg, false,
+kill, ln, losetup, ls, mkdir, mkfifo, readlink, rm, switch_root, sleep, sync,
+true, and uname.</p>
+
+<p>The low hanging fruit is cpio, dd, ps, mv, and pivot_root.</p>
+
+<p>The "kinit" command is another gratuitous rename, it's init running as PID 1.
+The halt, poweroff, and reboot commands work with it.</p>
+
+<p>I've got mount and umount queued up already, fstype and nfsmount go with
+those. (And probably smbmount and p9mount, but this hasn't got one. Those
+are all about querying for login credentials, probably workable into the
+base mount command.)</p>
+
+<p>The ipconfig command here has a built in dhcp client, so it's ifconfig
+and dhcpcd and maybe some other stuff.</p>
+
+<p>The resume command is... weird. It finds a swap partition and reads data
+from it into a /proc file, something the kernel is capable of doing itself.
+(Even though the klibc author
+<a href=http://www.zytor.com/pipermail/klibc/2006-June/001748.html>attempted
+to remove</a> that capability from the kernel, current kernel/power/hibernate.c
+still parses "resume=" on the command line). And yet various distros seem to
+make use of klibc for this.
+Given the history of swsusp/hibernate (and
+<a href=http://lwn.net/Articles/333007>TuxOnIce</a>
+and <a href=http://lwn.net/Articles/242107>kexec jump</a>) I've lost track
+of the current state of the art here. Ah, Documentation/power/userland-swsusp.txt
+has the API docs, and <a href=http://suspend.sf.net>here's a better
+tool</a>...</p>
+
+<p>So the list of things actually in klibc are:</p>
+
+<blockquote><b>
+<span id=klibc_cmd>
+cat chroot dmesg false kill ln losetup ls mkdir mkfifo readlink rm switch_root
+sleep sync true uname
+
+cpio dd ps mv pivot_root
+mount nfsmount fstype umount
+sh gunzip gzip zcat
+kinit halt poweroff reboot
+ipconfig
+resume
+</span>
+</b></blockquote>

+<a name=glibc />
+<h2>glibc</h2>
+
+<p>Rather a lot of command line utilities come bundled with glibc:</p>
+
+<blockquote><b>
+catchsegv getconf getent iconv iconvconfig ldconfig ldd locale localedef
+mtrace nscd rpcent rpcinfo tzselect zdump zic
+</b></blockquote>
+
+<p>Of those, musl libc only implements ldd.</p>
+
+<p>catchsegv is a rudimentary debugger, probably out of scope for toybox.</p>
+
+<p>iconv has been <a href="#susv4">previously discussed</a>.</p>
+
+<p>iconvconfig is only relevant if iconv is user-configurable; musl uses a
+non-configurable iconv.</p>
+
+<p>getconf is a posix utility which displays several variables from
+unistd.h; it probably belongs in the development toolchain.</p>
+
+<p>getent handles retrieving entries from passwd-style databases
+(in a rather lame way) and is trivially replacable by grep.</p>
+
+<p>locale was discussed under <a href=#susv4>posix</a>.
+localedef compiles locale definitions, which musl currently does not use.</p>
+
+<p>mtrace is a perl script to use the malloc debugging that glibc has built-in;
+this is not relevant for musl, and would necessarily vary with libc. </p>
+
+<p>nscd is a name service caching daemon, which is not yet relevant for musl.
+rpcinfo and rpcent are related to rpc, which musl does not include.</p>
+
+<p>The remaining commands involve glibc's bundled timezone database,
+which seems to be derived from the <a href=http://www.iana.org/time-zones>IANA
+timezone database</a>. Unless we want to maintain our own fork of the
+standards body's database like glibc does, these are of no interest,
+but for completeness:</p>
+
+<p>tzselect outputs a TZ variable correponding to user input.
+The documentation does not indicate how to use it in a script, but it seems
+that Debian may have done so.
+zdump prints current time in each of several timezones, optionally
+outputting a great deal of extra information about each timezone.
+zic converts a description of a timezone to a file in tz format.</p>
+
+<p>None of glibc's bundled commands are currently of interest to toybox.</p>

+<h2>Stand-Alone Shell</h2>
+
+<p>Wikipedia has <a href=http://en.wikipedia.org/wiki/Stand-alone_shell>a good

+a stopping point, and then <a href=http://www.baiti.net/sash>"sash plus

+that provides 40 commands.</p>
+
+<p>Sash is a shell with built-in commands. It doesn't have a multiplexer
+command, meaning "sash ls -l" doesn't work (you have to go "sash -c 'ls -l'").
+</p>
+
+<p>The list of commands can be obtained via building it and doing

+<h2>nash:</h2>
+
+<p>Red Hat's nash was part of its "mkinitrd" package, replacement for a shell
+and utilities on the boot floppy back in the 1990's (the same general idea
+as BusyBox, developed independently). Red Hat discontinued nash development
+in 2010, replacing it with dracut (which collects together existing packages,
+including busybox).</p>
+
+<p>I couldn't figure out how to beat source code out of
+<a href=http://pkgs.fedoraproject.org/git/mkinitrd>Fedora's current git</a>
+repository. The last release version that used it was Fedora Core 12
+which has <a href=http://archive.fedoraproject.org/pub/archive/fedora/linux/releases/12/Fedora/source/SRPMS/mkinitrd-6.0.93-1.fc12.src.rpm>a source rpm</a>
+that can be unwound with "rpm2cpio mkinitrd.src.rpm | cpio -i -d -H newc
+--no-absolute-filenames" and in there is a mkinitrd-6.0.93.tar.bz2 which
+has the source.</p>
+
+<p>In addition to being a bit like a command shell, the nash man page lists the
+following commands:</p>
+
+<blockquote><p>
+access echo find losetup mkdevices mkdir mknod mkdmnod mkrootdev mount
+pivot_root readlink raidautorun setquiet showlabels sleep switchroot umount
+</p></blockquote>
+
+<p>Oddly, the only occurrence of the string pivot_root in the nash source code
+is in the man page, the command isn't there. (It seems to have been removed
+when the underscoreless switchroot went in.)</p>
+
+<p>A more complete list seems to be the handlers[] array in nash.c:</p>
+
+<blockquote><p>
+access buildEnv cat cond cp daemonize dm echo exec exit find kernelopt
+loadDrivers loadpolicy mkchardevs mkblktab mkblkdevs mkdir mkdmnod mknod

+umount waitdev
+</p></blockquote>
+
+<p>This list is nuts: "plymouth" is an alias for "null" which is basically
+"true" (which thie above list doesn't have). Things like buildEnv and
+loadDrivers are bespoke Red Hat behavior that might as well be hardwired in
+to nash's main() without being called.</p>
+
+<p>Instead of eliminating items
+from the list with an explanation for each, I'm just going to cherry pick
+a few: the device mapper (dm, raidautorun) is probably interesting,
+hotplug (may be obsolete due to kernel changes that now load firmware
+directly), and another "resume" ala klibc.</p>
+
+<p>But mostly: I don't care about this one. And neither does Red Hat anymore.</p>

+<p>Back in 2008, the BSD guys vented some busybox-envy
+<a href=http://beastiebox.sourceforge.net>on sourceforge</a>. Then stopped.
+Their repository is still in CVS, hasn't been touched in years, it's a giant
+hairball of existing code sucked together. (The web page says the author
+is aware of crunchgen, but decided to do this by hand anyway. This is not
+a collection of new code, it's a katamari of existing code rolled up in a
+ball.)</p>
+
+<p>Combining the set of commands listed on the web page with the set of

+
+<p>Apparently lv is the missing link between ed and vi, copyright 1982-1997 (do
+not want), ex is another obsolete vi mode, lesskey is "used to
+specify a set of key bindings to be used with less", and csh is a shell they
+sucked in (even though they have mksh?), [ is an alias for test. Several more bsd-isms that don't have Linux
+equivalents (even in the ubuntu "install this package" search) are
+disklabel, fsck_ffs, mount_ffs, and pfctl. And wiconfig is a
+wavelan interface network card driver utility. Subtracting all that and the

+
+<p>In 2003 Jeff moved to Japan and handed
+the project off to people who allowed it to roll to a stop. The website
+turned into a mess of 404 links, the navigation indexes stopped being
+updated over a decade ago, and the project's CVS repository suffered a
+hard drive failure for which there were no backups. The project continued
+to put out "releases" through 2014 (you have to scroll down in the "news"
+section to find them, the "HTTP download" section in the nav bar on the
+left hasn't been updated in over a decade), which were hand-updated tarball
+snapshots mostly consisting of software from the 1990's. For example the
+2014 release still contained ipfwadm, the package which predated ipchains,
+which predated iptables, which is in the process of being replaced by
+nftables.</p>
+
+<p>Nevertheless, people still try to use this because (at least until the

+<p>A bunch of packages (<b>inotify-tools, input-event-demon, ipsec-tools, netifd,
+keepalived, mobile-broadband-provider-info, nuttp, readline, snort,
+snort-barnyard, socat, sqlite, sysklogd, sysstat, tcl, ubus, uci, udev,
+unionfs, uqmi, usb_modeswitch, usbutils, util-linux</b>)
+are hard to evaluate because
+uclinux has directories for them, but their source isn't actually in the
+uclinux tree. In some of these the makefiles download a git repo during
+the build, so I'm assuming you can build the external package if you really
+care. (Even when I know what these packages do, I'm skipping them
+because uclinux doesn't actually contain them, and any given snapshot
+of the build system will bitrot as external web links change over time.)</p>
+
+<p>Other packages are orphaned, meaning they're not mentioned from any Kconfig
+or Makefiles outside of their directory, so uclinux can't actually build
+them: <b>mbus</b> is an orphaned i2c test program expecting to run in some sort
+of hardwired hardware context, <b>mkeccbin</b> is an orphaned "ECC annotated
+binary file" generator (meaning it's half of a flash writer),
+<b>wsc_upnp</b> is a "Ralink WPS" driver (some sort of stale wifi chip)...</p>
+
+<p>The majority of the remaining packages are probably not of interest to
+toybox due to being so obsolete or special purpose they may not actually be
+of interest to anybody anymore. (This list also includes a lot of
+special-purpose network back-end stuff that's hard for anybody but
+datacenter admins to evaluate the current relevance of.)</p>

+
+<p>This stuff is all over the place: arj, lha, rar, and zoo are DOS archivers,
+ethattach describes itself as just "a network tool",
+mail is a textmode smtp mailer literally described as "Some kind of mail
+proggy" in uclinux's kconfig (as opposed to clamsmtp and smtpclient and
+so on), this gettyd isn't a generic version but specifically a
+hardwired ppp dialin utility, mgetty isn't a generic version but is combined
+with "sendfax", hostap is an intersil prism driver, wlan-ng is also an
+intersil prism dirver, null is a program to intentionally dereference a
+null pointer (in case you needed one), iso_client is a
+"Demo Application for the USB Device Driver", kendin-config is
+"for configuring the Micrel Kendin KS8995M over QSPI", speedtouch configures
+a specific brand of asdl modem, portmap is part of Anfs,
+ferret, linux-igd, and miniupnp are all upnp packages,
+lanbypass "can be used to control the LAN
+bypass switches on the Advantech x86 based hardware platforms", lcd is
+"test of lcddma device driver" (an out-of-tree Coldfire driver apparently
+lost to history, the uclinux linux-2.4.x directory has a config symbol for
+it, but nothing in the code actually _uses_ it...), qspitest is another
+coldfire thing, mii-tool-fec is
+"strictly for the FEC Ethernet driver as implemented (and modified) for
+the uCdimm5272", rtc-ds1302 and rtc-m41t11 are usermode drivers for specific
+clock chips, stunnel is basically "openssl s_client -quiet -connect",
+potrace is a bitmap to vector graphic converter, radauth performs command line
+authentication against a radius server,
+clamav, klaxon, ferret, l7-protocols, and nessus are very old network security
+software (it's got a stale snapshot of nmap too), xl2tpd is a PPP over UDP
+tunnel (rfc 2661), zebra is the package quagga replaced,
+lilo is the x86-only bootloader that predated grub (and recently discontinued
+development), lissa is a "framebuffer graphics demo" from
+1998, the squashfs package here is the out of tree patches for 2.4 kernels
+and such before the filesystem was merged upstream (as opposed to the
+squashfs-new package which is a snapshot of the userspace tool from 2011),
+load is basically "dd file /dev/spi", version is basically "cat /proc/version",
+microwin is a port of the WinCE graphics API to Linux, scep is a 2003
+implementation of an IETF draft abandoned in 2010, tpt depends on
+Andrew Morton's 15 year old unmerged "timepegs" kernel patch using the pentium
+cycle counter, vpnled controls a light that reboots systems (what?),
+w3cam is a video4linux 1.0 client (v4l2 showed up during 2.5 and support for
+the old v4l1 was removed in 2.6.38 back in 2011), busybox ate tinylogin
+over a decade ago, lrpstat is a java network monitor
+from 2001, lrzsz is zmodem/ymodem/zmodem, msntp and stp implement rfc2030
+meaning it overflows in 2036 (the package was last updated in 2000), rdate
+is rfc 868 meaning it also overflows in 2036 (which is why ntp was invented
+a few decades back), reiserfsprogs development stopped abruptly after
+Hans Reiser was convicted of murdering his wife Nina (denying it on the
+stand and then leading them to the body as part of his plea bargain during
+sentencing)...
+</p>
+
+<p>Seriously, there's a lot of crap in there. It's hard to analyze most
+of it far enough to prove it _doesn't_ do anything.</p>
+
+<h3>Non-toybox programs</h3>
+
+<p>The following software may actually still do something intelligible
+(although the package versions tend to be years out of date), but
+it's not a direction toybox has chosen to go in.</p>
+
+<p>There are several programming languages (<b>bash, lua, jamvm, tinytcl,
+perl, python</b>) in there. Maybe someone somewhere wants a 2008 release of a
+java virtual machine tested to work on nommu systems (jamvm), but it's out
+of scope for toybox.</p>
+
+<p>A bunch of benchmark programs: <b>cpu, dhrystone, mathtest, nbench, netperf,
+netpipe, and whetstone</b>.</p>
+
+<p>A bunch of web servers: <b>appWeb, boa, fnord (via tcpserver), goahead, httpd,
+mini_httpd, and thttpd</b>.</p>
+
+<p>A bunch of shells: <b>msh</b> is a clever (I.E. obfuscated) little shell,
+<b>nwsh</b> is "new shell" (that's what it called itself in 1999 anyway),
+<b>sash</b> is another shell with a bunch of builtins (ls, ps, df, cp, date, reboot,
+and shutdown, this roadmap analyzes it <a href="#sash">elsewhere</a>),
+<b>sh</b> is a very old minix shell fork, and <b>tcsh</b> is also a shell.</p>
+
+<p>Also in this category, we have:</p>
+
+<blockquote><b><p>
+dropbear jffs-tools jpegview kexec-tools bind ctorrent
+iperf iproute2 ip-sentinel iptables kexec
+nmap oggplay openssl oprofile p7zip pppd pptp play vplay
+hdparm mp3play at clock
+mtd-utils mysql logrotate brcfg bridge-utils flashw
+ebtables etherwake ethtool expect gdb gdbserver hostapd
+lm_sensors load netflash netstat-nat
+radvd recover rootloader resolveip rp-pppoe
+rsyslog rsyslogd samba smbmount squashfs-new squid ssh strace tip
+uboot-envtools ulogd usbhubctrl vconfig vixie-cron watchdogd
+wireless_tools wpa_supplicant
+</p></b></blockquote>
+
+<p>An awful lot of those are borderline: play and vplay are wav file
+audio players, there's oprofile _and_ readprofile (which just reads kernel
+profiling data from /proc/profile),
+radvd is a "routr advertisement daemon" (ipv6 stateless autoconf),
+ctorrent is a bittorent client,
+lm_sensors is hardware (heat?) monitoring,
+resolveip is dig only less so,
+rp-pppoe is ppp over ethernet,
+ebtables is an ethernet version of iptables (for bridging),
+their dropbear is from 2012, and that ssh version is from 2011
+(which means it's about nine months too _old_ to have the heartbleed bug).
+There's both ulogd and ulogd2 (no idea why), and pppd is version 2.4 but
+there's a ppd-2.3 directory also.</p>
+
+<p>Lots of flash stuff:
+flashw is a flash writer, load is an spi flash loader, netflash writes
+to flash via tftp,
+recover is also a reflash daemon intended to come up when the system can't boot,
+rootloader seems to be another reflash daemon but without dhcp.</p>
+
+<h3>Already in roadmap</h3>
+
+<p>The following packages contain commands already in the toybox roadmap:</p>
+
+<blockquote><b><p>
+agetty cal cksum cron dhcpcd dhcpcd-new dhcpd dhcp-isc dosfstools e2fsprogs
+elvis-tiny levee fdisk fileutils ftp ftpd grep hd hwclock inetd init ntp
+iputils login module-init-tools netcat shutils ntpdate lspci ping procps
+proftpd rsync shadow shutils stty sysutils telnet telnetd tftp tftpd traceroute
+unzip wget mawk net-tools
+</p></b></blockquote>
+
+<p>There are some duplicates in there, levee is a tiny vi implementation
+like elvis-tiny, ntp and ntpdate overlap, etc.</p>
+
+<p>Verdict: We don't really need to do a whole lot special for nommu
+systems, just get the existing toybox roadmap working on nommu and
+we're good. The uClinux project can rest in peace.</p>
+
+<hr />
+<h2>Requests:</h2>
+
+<p>The following additional commands have been requested (and often submitted)
+by various users. I _really_ need to clean up this section.</p>
