Upcoming Changes
0.7-2
Deprecate virtual_memory_page_size; use get_virtual_memory_page_size() instead. (#132)
CMake improvements:
- Generate container node sizes using CMake, which makes cross-compiling easier (#129)
- Set
CMAKE_RUNTIME_OUTPUT_DIRECTORY properly to support shared libraries (#132)
0.7-1
Just bugfixes:
- CMake: automatically link libatomic on platforms where that is necessary (#95)
- catch small block sizes of
memory_pool (#113)
- fix buffer overflow in
memory_pool_collection's array allocation (#99)
- fix compatibility with Windows UWP (#102)
- fix computation of
memory_pool::min_block_size (#110)
- fix debug assertion in free lists (#111)
0.7
BREAKING: Removed the use of the compatibility library to automatically generate macros and workaround for older compilers.
The important compatibility workarounds like the __builtin_clz extension are still used, but workarounds for missing C++11 library features have been removed.
In particular, the library now requires compiler support for noexcept, constexpr, alignof and thread_local.
This means that GCC 4.8 and Visual Studio version 12.0 (both released in 2013), are now longer supported.
Adapter
BREAKING: Remove Mutex support from allocator_reference and consequently from std_allocator, allocator_deleter, ...
Embedding the Mutex with the reference was fundamentally broken and unusable to ensure thread safety.
Use a reference to a thread_safe_allocator instead, which actually guarantees thread safety.
Allocator
Add ability to query the minimal block size required by a memory_pool or memory_stack that should contain the given memory.
Due to internal data structures and debug fences this is more than the naive memory request, so it can be computed now.
Bugfixes
- more CMake improvements for cross-compiling, among others
- bugfixes to support UWP (#80), VxWorks (#81) and QNX (#85, #88, among others)
- better support missing container node size (#59, #72, among others)
- fix alignment issues in debug mode
- fix tracking for allocators without block allocators
