-2.2.0
+2.3.0
General release
- - Changed: CMake is used for build libcds. Ancient build.sh is removed
+ - Changed: cds::gc::HP is totally refactored:
+ - simplified internal structures;
+ - added ability to specify an external allocator for internal data;
+ - external API for gc::HP is slightly changed: now scan type
+ cannot be changed on the fly; it can be specified only in
+ construction time.
+ - Changed: cds::gc::DHP is totally refactored to overcome some internal
+ limitations. Now gc::DHP is fully adaptive variant of Hazard Pointer
+ SMR, any dependencies on count of thread are removed, count of retired
+ data and hazard pointers per thread are increased automaticaly by perforce.
+ External API of gc::DHP class is changed: now only initial count
+ of hazard pointers can be specified in the constructor. Like new gc::HP,
+ the new gc::DHP supports an external allocator.
+ - Changed: exception handling. Now, exceptions raise by invoking new
+ cds::throw_exception() function. If you compile your code with exception disabled,
+ the function prints an exception message to stdout and calls abort()
+ instead of throwing. You can provide your own cds::throw_exception() function
+ and compile libcds with -DCDS_USER_DEFINED_THROW_EXCEPTION.
+ - Added: erase_at( iterator ) function to MichaelHashSet/Map and SplitListSet/Map
+ based on IterableList
+ - Fixed a bug in BronsonAVLTreeMap::extract_min()/extract_max()/clear().
+ - Removed: signal-handled threaded uRCU (cds::urcu::signal_threaded) due
+ bad performance
+ - Added more flat-combining queue tests, thanks to Marsel Galimullin.
+ - Changed cmake scripts to support MacOS and ARMv7/ARMv8 (64 bit),
+ thanks to Michail Komarov (https://github.com/Nemo1369)
+ - Stress tests: removed command line parameter --detail-level and
+ envvar CDSTEST_DETAIL_LEVEL for reducing compile time and executable size.
+ To make full testset compile libcds with -DCDS_STRESS_TEST_LEVEL=N where
+ N is 1 or 2.

+2.2.0 04.01.2017
+ General release
+ - Changed: CMake is used for build libcds. Ancient build.sh has been removed
- Changed: unit and stress tests are migrated to googletest framework
- Added: IterableList - an implementation of ordered list with
- thread-safe iterator. MichaelSet/Map supports this type of
- ordered list and thread-safe iterable too.

- Added: wait strategies for flat combining technique. Based on
- research of Marsel Galimullin and Nikolai Rapotkin.
+ research by Marsel Galimullin and Nikolai Rapotkin.
+ - Fixed: SkipList erase() and find() bugs that cause to infinite loop
+ or to program crash in rare case.
- Fixed: serious bug in MichaelSet::emplace() function
New node was created twice from the arguments by move semantics.
However, move semantics may change internal state of the argument
- that can lead to an incorrect element in the set and even
- to an incorrect key that breaks the set logic.

- Fixed: bug in FeldmanHashSet::erase_at( iterator ): due an error
- in precondition checking the function can incorrectly return false.

- Fixed: possible double-free case in flat combining algorithm.

- Changed: cds::opt::buffer option is divided to initialized
(cds::opt::v::initialized_dynamic_buffer, cds::opt::v::initialized_static_buffer)
and uninitialized (cds::opt::v::uninitialized_dynamic_buffer, cds::opt::v::uninitialized_static_buffer)
ones. The old cds::opt::v::dynamic_buffer and cds::opt::v::static_buffer classes
are removed.
+ - Removed: TsigasCysleQueue (due undecidable ABA-problem)
+ - Removed: Michael's allocator cds/memory/michael/allocator.h
- Fixed: use-after-free bug in VyukovMPMCCycleQueue internal buffer.
To prevent this bug the queue uses an uninitialized buffer now.
- Fixed: rare priority inversion bug in MSPriorityQueue
- Added: for minimizing runtime of stress test the detail level for some test is added.
Command line argument --detail-level=N specifies what test should be ran: each
- test with level not great than N will be ran. Instead of command line arg
- the enviromnent variable CDSTEST_DETAIL_LEVEL=N can be used.
- By default, the detail level is 0 that means only small set of the some test will be ran.
