Post-release Patches
-
Atomic:
-
Using 64-bit atomic operations on 32-bit x86 with gcc versions older
than 4.7 and compatible compilers can result in generation of incorrect
code. This problem is fixed in this
commit.
Updated Libraries
-
Atomic:
-
Added the static constant
atomic<T>::is_always_lock_free
for conformance with C++17. The constant indicates that the given
specialization always provides lock-free implementation of atomic
operations.
-
Improved support of Oracle Studio on x86 targets.
-
Container:
-
Context:
-
#11687 Xcode (Apple clang) and thread_local
-
#12114 context does not preserve fpu context on ios arm64 devices
(fixed for other architecturs too)
-
#12411 fpu registers not preserved with O2 optimizations in Visual
Studio (fixed for other architecturs too)
-
#12551 building boost on arm64 causes error: unknown directive
-
reduced signatur for ontop-functions
-
unit-test for private fcontext-API
-
performance-test for ucontext and fcontext fixed
-
Fiber:
-
unbounded_channel and bounded_channel marked as deprecated
-
new classes buffered_channel and unbuffered_channel
-
performance improved
-
Fusion:
-
Fixed
fusion::vector buggy constructors (Thanks
to Lee Clagett).
-
BOOST_FUSION_ADAPT* and BOOST_FUSION_DEFINE* now allow empty structures. (#6592)
-
BOOST_FUSION_DEFINE* allows move constructor and assignment.
(#10099)
-
Adaptor for
std::array (Thanks to Mateusz Łoskot).
(#8241)
-
Fixed returning temporary variable warnings on MSVC.
-
Geometry:
-
Improvements:
-
Intersection: take care that output is valid (work in progres,
not yet finished - but more is valid)
-
Solved tickets:
-
#12289
Avoid warning/compilation error for std::cout
-
#12412
Invalid result of covered_by() with geographic Points and Boxes
-
#12413
rtree::remove() not working properly with geographic Points
-
Hash:
-
Interprocess:
-
Intrusive:
-
Lexical Cast:
-
Fixed issue found by
-fsanitize=undefined #21
-
Log:
-
General changes:
-
Removed the previously deprecated
type_info_wrapper.
-
New features:
-
Added a way to access the current file name from the text file
sink backend. The file name can be obtained with the
get_current_file_name method.
-
Bug fixes:
-
Fixed compilation errors for Android API prior to version 21.
-
Streaming operators now take scalar types and enums by value.
This allows to output static constants and bitfields directly
into formatting stream and record stream. (#11998)
-
Fixed auto-detection of native syslog API. (#12600)
-
In UDP socket based syslog backend implementation, changed
the syslog message format for better compliance with RFC3164.
-
File close handler installed in text file sink backend is no
longer called if the file is not open yet.
-
See changelog
for more details.
-
Metaparse:
-
Improved the implementation of
BOOST_METAPARSE_STRING
-
The maximal string length limit has been increased to 2048
-
The maximal string length limit can be extended beyond 2048
by regenerating some of the Boost headers using a script (part
of the library)
-
The string length limit can be changed within a compilation
unit
-
Move:
-
Improved experimental adaptive sort algorithm performance
-
Activate BOOST_MOVE_FORCEINLINE
-
Optional:
-
Added two new in-place constructors. They work similarly to
emplace()
functions: they initialize the contained value by perfect-forwarding
the obtained arguments. One constructor always initializes the contained
value, the other based on a boolean condition.
-
Syntax
o =
{} now correctly un-initializes
an optional, just
like in std::optional.
-
Fixed
optional<optional<T>&>
initialization. (#12203)
-
Optional constructors are sfinae-friendly. This fixes interaction
with
std::tuple. (#12563)
-
Phoenix:
-
Most of modules now support C++11 variadic templates.
-
Fixed type deduction failure with result type.
-
Suppress unused warnings.
-
Fixed too few arguments error on binary math functions.
-
Added workarounds for older compiler.
-
Python:
-
Added (basic) support for C++11 (std::shared_ptr, std::unique_ptr)
-
Incorporated an extension API to wrap NumPy
-
Removed obsolete bits and pieces
-
Test:
-
Boost.test v3.4 see the Change
log section for more details.
-
New feature:
per_element
and lexicographic
modifiers of BOOST_TEST
can also be applied to string comparison
-
Breaking change: colons that appear in test case names are replaced
with underscores
-
Bug fixes
-
TypeIndex:
-
Added
runtime_cast
to the library as an emulation of dynamic_cast.
Thanks to Chris Glover for the implementation. See runtime_cast
reference for more info.
-
Internals of the CTTI were made more platform independant, due to
change of the
std::size_t
type to unsigned int.
-
Units:
-
Fix inspection warnings
-
updated physico-chemical constants to CODATA 2014 values
-
define biot correctly as 10 Ampere
-
Unordered:
-
Fix an exception safety issue in assignment.
-
Use
std::allocator_traits where available,
and support modern style rebind (#12459).
-
Add some allocator aware constructors.
-
Use the hint iterator in
emplace_hint.
-
Fixed some warnings.
-
See the changelog
for more details.
