libcds v2.3.0 Release Notes

Release Date: 2017-07-31 // over 6 years ago
    • 🔨 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.
    • 🛠 Flat Combining: fixed memory-order bug that can lead to crash on weak ordered
      architecture like PowerPC or ARM
    • ➕ 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.
    • 🔨 Changed: refactoring cds::backoff::exponential and cds::backoff::delay
      back-off strategies to avoid static data members in template classes.
    • ✅ The library is extensively tested on x86-64, PowerPC and AArch64,
      thanks to GCC Compile Farm project
