HISTORY

1.3.2

  1. [FIX] #16 : document of LIBCOPP_DISABLE_ATOMIC_LOCK and LIBCOPP_DISABLE_THIS_MT .

  2. [FIX] #18 : 'xx' is not a member of 'xxx {aka xxx}' .

  3. [OPTIMIZE] cotask::task can capture all integer type of return value now.

  4. [FIX] Remove warning of c++20 coroutine options when project use both languages of cxx and not cxx

1.3.1 (2020-07-06)

  1. Fix compiler version checker for C++20 coroutine

  2. Add cmake interface option and features for targets

  3. Update documents

1.3.0 (2020-07-02)

  1. [OPTIMIZE] Using cmake export to generate module files

  2. [OPTIMIZE] Change default visibility of symbols to hidden, we support dll on windows now.

  3. [FIX] Rename task::await into task::await_task, Some compile don’t allow await_task as function name.

  4. [BOOST] Merge boost.context 1.73.0

  5. [FEATURE] Implement context of windows fiber and SetUnhandledExceptionFilter is available to catchunhandled exception in coroutine action

  6. [OPTIMIZE] Catch and rethrow unhandle exception after coroutine resumed when using C++11 or upper, most APIs are exception safe now.

  7. [OPTIMIZE] Remove TTASK_MACRO in cotask::task, task id now is always set uint64_t and use the id allocator with thread cache.

  8. [OPTIMIZE] Fix Warning: client switching stacks? in unit test when enable valgrind support.

  9. [FEATURE] Enable -DLIBCOPP_FCONTEXT_USE_TSX=ON for default.

BREAK CHANGES & UPGRADE GUIDE FROM 1.2.X

  • Rename cotask::task::await into cotask::task::await_task

  • Replace cotask::task<TCO_MACRO, TTASK_MACRO> with cotask::task<TCO_MACRO> , we don’t allow to custom id allocator now.

  • Replace cotask::core::standard_int_id_allocator<uint64_t> with copp::util::uint64_id_allocator , we don’t allow to custom id allocator now.

  • Require gcc 4.7+, MSVC 14+(Visual Studio 2015)>)

  • Require cmake 3.12.0 or upper

1.2.1 (2019-10-04)

  1. [OPTIMIZE] Add options to disable TLS usage for this_task and this_coroutine to reduce cache miss on single thread situation.

  2. [OPTIMIZE] Implement jump_to(…) as static inline to reduce code cache miss.

  3. [OPTIMIZE] Implement coroutine_context_callback(…) as static local symbol to reduce code cache miss.

1.2.0 (2019-08-20)

  1. [OPTIMIZE] Add more unit test.Increase coverage to 90%+.

  2. [OPTIMIZE] Rewrite toolchain detection scripts, support clang-cl now.

  3. [BOOST] merge boost.context 1.71.0.

  4. [FIX] Fix a coredump problem when task_ptr is reset when await_task other tasks.

  5. [OPTIMIZE] Optimize timer implement, task_manager support modify task timer now.

  6. [OPTIMIZE] A task can only be added to one task_manager now, and when finish task with task’s API, task_manager will also be cleanup.

  7. [OPTIMIZE] Fix some warning when compiling with gcc 9+ and clang 8+.

  8. [OPTIMIZE] Use pthread for TLS when both c++11 thead_local and pthread are available. It will reduce the minimal stack size.

  9. [OPTIMIZE] Fix and add some example codes and documents.
