Patches

• Locale Patch - Fixes a bug which causes boost::locale::utf::utf_traits to accept some invalid UTF-8 sequences, which is a possible security flaw.

New Libraries

• Heap:
  • Priority queue data structures, from Tim Blechmann.

Updated Libraries

• Asio:
  • Added a new class template basic_waitable_timer based around the C++11 clock type requirements. It may be used with the clocks from the C++11 <chrono> library facility or, if those are not available, Boost.Chrono. The typedefs high_resolution_timer, steady_timer and system_timer may be used to create timer objects for the standard clock types.
  • Added a new windows::object_handle class for performing waits on Windows kernel objects. Thanks go to Boris Schaeling for contributing substantially to the development of this feature.
  • On Linux, connect() can return EAGAIN in certain circumstances. Remapped this to another error so that it doesn't look like a non-blocking operation (#6048).
  • Fixed a compile error on NetBSD (#6098).
  • Fixed deadlock on Mac OS X (#6275).
  • Fixed a regression in buffered_write_stream (#6310).
  • Fixed a non-paged pool "leak" on Windows when an io_service is repeatedly run without anything to do (#6321).
  • Reverted earlier change to allow some speculative operations to be performed without holding the lock, as it introduced a race condition in some multithreaded scenarios.
  • Fixed a bug where the second buffer in an array of two buffers may be ignored if the first buffer is empty.
• Chrono:
  • Bug Fixes:
    • #6092 Input from non integral durations makes the compiler fail.
    • #6093 [1/3]second fails as valid duration input.
    • #6113 duplicate symbol when BOOST_CHRONO_HEADER_ONLY is defined.
    • #6243 Sandia-pgi-11.9: more than one instance of overloaded function "min" matches.
    • #6257 process_cpu_clock::now() on linux gives time_points 1/1000 times.
• Container:
  • Fixed bugs #6499, #6336, #6335, #6287, #6205, #4383.
  • Added allocator_traits support for both C++11 and C++03 compilers through an internal allocator_traits clone.
• Filesystem:
  • Fix #3714, Added test cases and fixes for class path errors when assignment or append used self or portion of self as source.
  • Fix #4889, #6320, Locale codecvt_facet not thread safe on Windows. Move Windows, Mac OS X, locale and codecvt facet back to namespace scope. POSIX except OS X uses local static initialization (IE lazy) to ensure exceptions are catchable if environmental variables are misconfigured and to avoid use of locale("") if not actually used.
  • Fix #5652, recursive_directory_iterator fails on cyclic symbolic links. Thanks to Daniel Aarno for the patch.
  • Fix #5653, recursive_directory_iterator(error_code) can still throw filesystem_error.
  • Fix #5900, directory_iterator access violation on Windows if error is thrown. Thanks to Andreas Eckleder for the patch.
  • Fix #5900 comment 2, a bug in director_iterator construction with error_code argument that caused increment to be called without the ec argument being passed.
  • Fix #5989 by cleaning up test suite path_test.cpp code even though the ticket itself was not a defect, and clarifying docs; iteration over a path yields generic format.
  • Fix #5592, Change Windows codecvt processing from CP_THREAD_ACP to CP_ACP.
  • Operations function fixes for PGI compiler, thanks to Noel Belcourt.
  • Relax permissions test to reflect reality, particularly on the Sandia test platforms.
• Foreach:
  • Fix for #6131
• Geometry:
  • Fixed bugs
    • Distance for multi-geometries ignored specified distance strategy.
    • In difference for polygon/multi_polygon (reported 2011/10/24 on GGL-list).
    • Raise exception for calculation of distances of multi-geometrie(s) where one of them is empty
    • Multi DSV did not correctly use settings.
    • Self-intersections could sometimes be missed (introduced in 1.48).
    • Convex hull crashed on empty range (e.g. empty multi point).
  • Solved tickets
    • #6028 Documentation: closure.
    • #6178 Missing headerfile.
    • #6021 convex hull of multipoint.
  • Additional functionality
    • Support for line/polygon intersections and differences
    • Support for convert of segment/box of different point types
    • Support for append for multi point
    • Scalar functions (distance, area, length, perimeter) now throw an empty_input_exception on empty input
  • Documentation
    • Updated support status
  • Internal changes
    • Updates in specializations/not_implemented for distance/convert/assign/area
    • Move of wkt/dsv to io folder, making domains redundant
    • Strategy concepts assigned to zero to avoid clang warnings (patched by Vishnu)
• Graph:
  • Fixed bugs #5881, #6033, #6061, #6137, #6246, #6239, #6293, #6306, #6313 and #6371, plus others not in Trac.
  • Re-enabled LEDA graph support (thanks to Jens Muller for the patch).
  • Added documentation for edge_predecessor_recorder.
• Icl:
  • Fixed tickets #6095 and #6210.
  • Added move semantics for constructors, assignment operators and binary operators.
• Interprocess:
  • Fixed bugs #6531, #6412, #6398, #6340, #6319, #6287, #6265, #6233, #6147, #6134, #6058, #6054, #5772, #5738, #5622, #5552, #5518, #4655, #4452, #4383, #4297.
  • Fixed timed functions in mutex implementations to fulfill POSIX requirements: Under no circumstance shall the function fail with a timeout if the mutex can be locked immediately. The validity of the abs_timeout parameter need not be checked if the mutex can be locked immediately.
• Intrusive:
  • Fixed bugs #6347, #6223, #6153.
• Lexical cast:
  • Fixed bugs and warnings: #6127, #6132, #6159, #6182, #6186, #6193, #6264, #6290, #6298, #6400.
  • Better performance and less memory usage for boost::container::basic_string conversions.
• Locale:

• Thread:
  • Fixed Bugs:
    • #2309 Lack of g++ symbol visibility support in Boost.Thread.
    • #2639 documentation should be extended(defer_lock, try_to_lock, ...).
    • #3639 Boost.Thread doesn't build with Sun-5.9 on Linux.

    • #3975 Incorrect precondition for promise::set_wait_callback().
    • #4048 thread::id formatting involves locale
    • #4315 gcc 4.4 Warning: inline ... declared as dllimport: attribute ignored.
    • #4480 OpenVMS patches for compiler issues workarounds.
    • #4819 boost.thread's documentation misprints.
