Documentation

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

• Context:
  • switching library, from Oliver Kowalke.

Updated Libraries

• Algorithm:
  • Fixed is_sorted_until ; now matches the c++11 standard behavior on ranges with duplicate values.
  • Added range support for the rest of the search algorithms.
  • unhex now uses Boost.Exception to signal bad input.
• Asio:
  • Fixed an incompatibility between ip::tcp::iostream and C++11 (#7162).
  • Decorated GCC attribute names with underscores to prevent interaction with user-defined macros (#6415).
  • Added missing #include <cctype>, needed for some versions of MinGW.
  • Changed to use gcc's atomic builtins on ARM CPUs, when available (#7140).
  • Changed strand destruction to be a no-op, to allow strand objects to be destroyed after their associated io_service has been destroyed.
  • Added support for some newer versions of glibc which provide the epoll_create1() function but always fail with ENOSYS (#7012).
  • Changed the SSL implementation to throw an exception if SSL engine initialisation fails (#6303).
  • Fixed another regression in buffered_write_stream (#6310).
  • Implemented various minor performance improvements, primarily targeted at Linux x86 and x86-64 platforms.
• Config:
  • Deprecated a whole bunch of macros that were c++11 specific, but not named to show that they were c++11 specific. Made new macros with better names, and paired the old macros with the new ones. Updated the documentation to list the deprecated macros.
• Chrono:
  • #6918 Boost Chrono compilation failure on HP uX due to undefined pthread_getcpuclockid.
  • #6241 boost::chrono compilation problems without std::wstring support.
  • #6987 Documentation & C++11.
  • #7041 time_point.hpp depends on Boost.System.
  • #7042 Avoiding time_point and duration dependency on time.h and CLOCK_REALTIME.
  • #7058 Make it work when BOOST_NO_EXCEPTIONS is defined.
  • #7069 Misspellings in clock_string<thread_clock>.
  • #7081 WinError.h capitalization in boost/detail/win/basic_types.hpp.
• Geometry:
  • points accessed through a pointer (e.g. in a linestring) should now be specialized without the pointer. In previous versions a type my_point used like linestring<my_point*> had to be specalized like: template<> struct tag<my_point*>. Now the library itself removes the pointer before calling the traits class, so now it should be like: template<> struct tag<my_point>
  • intersection was sometimes wrong for integer points, fixed
  • documentation, order of parameters in simplify was wrong, fixed
  • 7030 spherical distance, fixed (by patch of Karsten Ahnert)
• Graph:
  • Refactored support for internal and bundled properties in Boost.Graph-provided graph types, and cleaned up named parameter functionality:
    • Enabled old-style (non-bundled) internal properties in compressed_sparse_row_graph.
    • Bundled properties should work correctly for all graph types and adaptors.
  • Bugs fixed:
    • #6993: Typo Bundled Properties document
    • #7002: Problem with initialization of CSR bidirectional graph
    • #7023: Enclose internal type graphml_reader in anonymous namespace
    • Other bugs and warnings not in Trac
• Hash:
  • Support the standard smart pointers.
  • hash_value now implemented using SFINAE to avoid implicit casts to built in types when calling it.
  • Updated to use the new config macros.
• Lexical cast:
  • Better performance, less memory usage for boost::array<character_type, N> and std::array<character_type, N> conversions.
  • Fixed bug with volatile input parameter #7157.
• Math:
  • Updated to use the new config macros.
• MSM:
  • Support for boost::any /docs/libs/1_51_0/libs/msm/doc/HTML/ch03s03.html#any-event or kleene /docs/libs/1_51_0/libs/msm/doc/HTML/ch03s04.html#kleene-event as acceptable events
  • Bugfix: compiler error with fsm internal table and none (compound) event.
  • Bugfix: euml::defer_ leading to stack overflow.
• Proto:
  • Proto transforms get pseudo-parameter pack expansion support for unpacking expressions. See the Release Notes for more information.
• Ratio:
  • #7075 Workaround for error: the type of partial specialization template parameter constant "n1" depends on another template parameter.
• Regex:
  • Updated to use the new config macros.
• Thread:
  • #4258 Linking with boost thread does not work on mingw/gcc 4.5.
  • #4885 Access violation in set_tss_data at process exit due to invalid assumption about TlsAlloc.
  • #6931 mutex waits forwever with Intel Compiler and /debug:parallel
  • #7044 boost 1.50.0 header missing.
  • #7052 Thread: BOOST_THREAD_PROVIDES_DEPRECATED_FEATURES_SINCE_V3_0_0 only masks thread::operator==, thread::operator!= forward declarations, not definitions.
  • #7066 An attempt to fix current_thread_tls_key static initialization order.
  • #7074 Multiply defined symbol boost::allocator_arg.
  • #7078 Trivial 64-bit warning fix on Windows for thread attribute stack size
  • #7089 BOOST_THREAD_WAIT_BUG limits functionality without solving anything
• Unordered:
  • Fix construction/destruction issue when using a C++11 compiler with a C++03 allocator (#7100).
  • Remove a try..catch to support compiling without exceptions.
  • Adjust SFINAE use to try to supprt g++ 3.4 (#7175).
  • Updated to use the new config macros.
• Wave:
  • See the Changelog for details.
• xpressive:
  • Work around buggy wide ctype facet on cygwin and mingw.
  • Work around absence of __isctype on some glibc implementations.
  • op::as shouldn't assume string::iterator != char*.
  • Fix assertion in cpp_regex_traits on libc++, thanks to John Fletcher.
