Documentation
Patches
-
Boost.Unordered patch
- Fixes a bug when compiled using a C++11 compiler, but with a C++03 allocator.
When inserting elements,
allocator_traits
detects that the node can be constructed using an accidental implicit conversion
which causes several problems.
-
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
- Algorithm:
-
A collection of
useful generic algorithms, from Marshall Clow. This includes several different
searching algorithms, as well as most of the new algorithms from the C++11
standard library
- Functional/OverloadedFunction:
-
Overload
different functions into a single function object, from Lorenzo Caminiti.
- LocalFunction:
-
Program
functions locally, within other functions, directly within the scope where
they are needed, from Lorenzo Caminiti.
- Utility/IdentityType:
-
Wrap
types within round parenthesis so they can always be passed as macro parameters,
from Lorenzo Caminiti.
Updated Libraries
-
Accumulators:
-
add missing
#include
<boost/throw_exception.hpp>, fixes #6702.
-
work around for msvc which allows ctor templates to be copy ctors,
fixes #6535.
-
shorten filenames to meet boost guidelines, fixes #6196.
-
Array:
-
add support for Boost.Hash #6791.
-
Asio:
-
Changed the
epoll_reactor
backend to do lazy registration for EPOLLOUT
events.
-
Fixed the
epoll_reactor
handling of out-of-band data, which was broken by an incomplete fix
in the last release.
-
Changed Asio's SSL wrapper to respect OpenSSL's
OPENSSL_NO_ENGINE
feature test #define
(#6432).
-
Fixed
windows::object_handle so that it works
with Windows compilers that support C++11 move semantics (such as
g++).
-
Improved the performance of strand rescheduling.
-
Added support for g++ 4.7 when compiling in C++11
mode (#6620).
-
Fixed a problem where
signal_set
handlers were not being delivered when the io_service
was constructed with a concurrency_hint
of 1 (#6657).
-
Bimap:
-
Remove spurious dependency on Boost.Serialization, fixes #3868.
-
Solve unused constructor parameter warning, fixes #5749.
-
Add key_type and mapped_type (leaving data_type for backward compatibility)
typedefs to map views, fixes #6031.
-
Chrono:
-
Fixed Bugs:
-
#6361
integer overflow in boost::chrono::process_real_cpu_clock::now()
under Windows 32bits.
-
#6628
compiler warning in process_cpu_clocks.hpp.
-
#6666
thread_clock.hpp needs pthread.h.
-
Concept Check:
-
Fixed:
-
#6738
Shadowed variable warning.
-
Filesystem:
-
Remove Filesystem Version 2 from the distribution. Version 3 is now
the only distributed version. Those still using V2 are urged to migrate
to V3 as soon as possible.
-
Add constexpr value_type preferred_separator to class path.
-
Fix #5118,
replace_extension
doesn't work as specified in documentation. The documentation, implementation,
and test cases have all had fixes applied. The documentation had
failed to mention that any existing extension is removed. The behavior
for simple cases has been reverted to the Version 2 behavior, but
with corrections so that complex replacements now work. Two test
cases from #5118
have been added.
-
Fix #3737,
Boost.Filesystem does not compile on Windows Mobile. On Windows,
<sys/stat.h> is no longer included.
-
Fix #4065,
Boost Filesystem lexicographic path comparison inconsistent. This
required multiple source code bug fixes and code cleanup, correcting
problems not related to lexicographical issues.
-
Add class path member function compare for consistency with std::string.
-
Tighten
BOOST_FILESYSTEM_DYN_LINK
and BOOST_FILESYSTEM_STATIC_LINK
logic in filesystem/config.hpp
so that one or the other is always defined, and both being defined
is a #error.
-
Fix #6690
and #6737,
resolving static linking related problems with VC++ 8 through 11.
Note that this fix may reintroduce codecvt thread safety problems
#4889,
#6320,
for these compilers if static linking is used.
-
Add
path::operator+=
and concat functions to tack on things like suffixes or numbers.
Suggested by Ed Smith-Rowland and others.
-
Fix #6809,
Implementation of
filesystem::rename() method for MS Windows is wrong,
by adding MOVEFILE_COPY_ALLOWED
to deal with renames across drives, volumes, file systems. Fix has
no effect on non-Windows systems.
-
Fix #6819,
A path operand with a source that was a one character array was treated
as empty, even if it wasn't empty. Such arrays can occur in unions
or in code using C variable length array idioms.
-
Fix #6932,
create_directories throws exception even if
error_code
is specified.
-
Foreach:
-
Revert fix for #6131
which caused more harm than good.
-
Geometry:
-
Fixed Bugs:
-
the return type of comparable projected point strategy for
integer points was wrong (integer), fixed
-
several robustness issues in intersection of segments and polygons,
fixed
-
invalid intersection output is filtered out

disjoint for multi_polygon's might incorrectly return true,
fixed

patch for alternative syntax multipoint, applied
-
6584
patch for bug in distance, applied
-
5730
same issue as 6584, fixed
-
6166
patch for missing transformation, applied
-
6696
invalid intersection output, was (by chance) already fixed
in Trunk before reported

*polygon/*polygon
-
Graph:

Fixed Bugs:
-
#4622
clear_vertex on a vertex with a self-loop can cause a segmentation
fault.

wrong.
-
#6242
isomorphism doesn't reset mapping.

-
#6573
BGL: boost::isomorphism routine fails with large graphs.
-
#6583
Dijkstra Visitor Concept docs probably show wrong type for
variable.
-
#6647

-
#6656
Dependent type in subgraph used without typename.
-
#6707
is_straight_line_drawing.hpp missing #include <map>.
-

inline?

#5800
-
Better performance, less memory usage and bugfixes for
boost::iterator_range<character_type*>

-
Locale:
-

-
Math:
-
Promoted math constants to be 1st class citizens, including convenient
access to the most widely used built-in float, double, long double

-
Corrected issue #6627
nonfinite_num_put formatting of 0.0 is incorrect based on
a patch submitted by K R Walker.
-
Changed constant initialization mechanism so that it is thread safe
even for user-defined types, also so that user defined types get
the full precision of the constant, even when
long
double does not. So for example
128-bit rational approximations will work with UDT's and do the right
thing, even though long double may be only 64 or 80 bits.

Fixed issue in
bessel_jy
which causes Y[sub 8.5](4[pi]) to yield a NaN.
