| <h4>1.44</h4> |
| |
| <p>Lots of fixes in this version, almost all are by Steven Watanabe.</p> |
| |
| <p>File descriptor fixes:</p> |
| |
| <ul> |
| <li> |
| <strong>Breaking change:</strong> |
| new constructors and <code>open</code> methods from file descriptors/handles for |
| <code>file_descriptor</code>, <code>file_descriptor_source</code> |
| and <code>file_descriptor_sink</code>. See |
| <a title="File descriptor devices referece" href="classes/file_descriptor.html">the documentation</a> |
| for details. The old methods are still available if you define |
| <code>BOOST_IOSTREAMS_USE_DEPRECATED</code> |
| (<a href="https://svn.boost.org/trac/boost/ticket/3517">#3517</a>). |
| </li> |
| <li> |
| Add <code>BOOST_IOSTREAMS_DECL</code> to |
| <code>file_descriptor_source</code> and |
| <code>file_descriptor_sink</code> fixing their use in dynamic libraries |
| (<a href="https://svn.boost.org/trac/boost/ticket/4335">#4335</a>). |
| </li> |
| <li> |
| Rejigger <code>file_descriptors</code> handling of |
| <code>std::ios_base::openmode</code> to match <code>std::fstream</code>. |
| In particular, truncate existing files, if |
| <code>std::ios_base::trunc</code> is passed |
| (<a href="https://svn.boost.org/trac/boost/ticket/3323">#3323</a>). |
| </li> |
| <li> |
| Open files in append mode on Windows instead of seeking to the end at every |
| write when <code>std::ios_base::app</code> is passed |
| (<a href="https://svn.boost.org/trac/boost/ticket/3323">#3323</a>). |
| </li> |
| </ul> |
| |
| <p>Compression/decompression fixes:</p> |
| |
| <ul> |
| <li> |
| Don't end the stream produced by a reading through a symmetric_filter |
| prematurely |
| (<a href="https://svn.boost.org/trac/boost/ticket/2318">#2318</a>). |
| </li> |
| <li> |
| Allow building zlib 1.2.4+, using a glob to include only source files that |
| actually exist |
| (<a href="https://svn.boost.org/trac/boost/ticket/4091">#4091</a>). |
| </li> |
| <li> |
| Fix compressing an empty string. |
| </li> |
| <li> |
| Allow bzip2 filters to be closed even if no input has been read |
| (<a href="https://svn.boost.org/trac/boost/ticket/3348">#3348</a>). |
| </li> |
| <li> |
| Throw an exception on an unexpected end of file in |
| <code>bzip2_decompressor</code> instead of going into an infinite loop |
| (<a href="https://svn.boost.org/trac/boost/ticket/2783">#2783</a>). |
| </li> |
| <li> |
| Reset the crc for zlib when we reuse a filter. |
| </li> |
| <li> |
| Make <code>gzip_decompressor</code> a <code>DualUseFilter</code> |
| (<a href="https://svn.boost.org/trac/boost/ticket/1579">#1579</a>). |
| </li> |
| <li> |
| Allow <code>bzip2_decompressor</code> to process multiple concatenated |
| streams |
| (<a href="https://svn.boost.org/trac/boost/ticket/3853">#3853</a>). |
| </li> |
| </ul> |
| |
| <p>Other fixes:</p> |
| |
| <ul> |
| <li> |

| (<a href="https://svn.boost.org/trac/boost/ticket/3851">#3851</a>). |
| </li> |
| <li> |

| (<a href="https://svn.boost.org/trac/boost/ticket/2356">#2356</a>). |
| </li> |
| <li> |
| On windows, open mapped files with just read/write permissions, rather than |
| full control - which might not be available |
| (<a href="https://svn.boost.org/trac/boost/ticket/2996">#2996</a>). |
| </li> |
| <li> |
| Make sure that <code>direct_streambuf</code> and |

| (<a href="https://svn.boost.org/trac/boost/ticket/4102">#4102</a>). |

| </li> |
| <li> |
| Several documentation improvements, including |

| (<a href="https://svn.boost.org/trac/boost/ticket/1612">#1612</a>). |
| </li> |
| <li> |
| Make the tests more reliable by using Boost.Filesystem's |
| <code>unique_path</code> instead of <code>tmpnam</code> |
| (<a href="https://svn.boost.org/trac/boost/ticket/2325">#2325</a>). |
| </li> |

| <h3>1.35</h3> |
| |
| <P>1. The semantics of <A HREF="functions/close.html"><CODE>close</CODE></A> has been modified:</P> |
| |
| <UL> |
| <LI>Calling <CODE>close</CODE> with a <CODE>std::ios_base::openmode</CODE> other than <CODE>in</CODE> or <CODE>out</CODE> is deprecated.</LI> |
| <LI>A new overload of <CODE>close</CODE> taking a single Device argument has been provided as a convenience.</LI> |
| <LI><A HREF="concepts/dual_use_filter.html">DualUseFilters</A> receive only one closure notification.</LI> |
| <LI><A HREF="guide/generic_streams.html">Generic streams and stream buffers</A> and <A HREF="guide/filtering_streams.html">filtering streams and stream buffers</A> are now <A HREF="concepts/closable.html">Closable</A>. For filtering streams and stream buffers, <CODE>close</CODE> calls <A HREF="classes/filtering_stream.html#pop"><CODE>pop</CODE></A>. |
| </UL> |
| |
| <P><EM>These changes will break some existing code</EM>. They were necessary to resolve inconsistencies in the prior specification that resulted in a number of reported bugs.</P> |
| |
| <P>2. The function template <a href="functions/slice.html"><code>slice</code></a> has been introduced as an alias of <a href="functions/restrict.html"><code>restrict</code></a>, for platforms that treat <code>restrict</code> as a keyword.</P> |
| |
| <P>3. Numerous bugs have been fixed, many relating to <a href="functions/close.html"><code>close</code></a>, <a href="functions/copy.html"><code>copy</code></a>, and <a href="classes/file_descriptor.html">file descriptors</a>.</P> |
