Changelog

1.6.1 (2023-05-02)

Fixes

  • PersistentTaskGroup no longer stores the history of unhandled exceptions and raises them as an exception group to prevent memory leaks (#54)

1.6.0 (2023-03-14)

Features

  • Add as_completed_safe() which enhances asyncio.as_completed() using PersistentTaskGroup (#52)

1.5.9 (2022-04-26)

Fixes

  • Improve checks for pidfd availability to avoid corner cases that may fail on Linux kernel 5.1 and 5.2 where signal.pidfd_send_signal() is available but os.pidfd_open() is not (#51)

1.5.8 (2022-04-25)

Fixes

  • Explicitly attach the event loop to the PidfdChildWatcher when first initialized (#50)

1.5.7 (2022-04-12)

Fixes

  • Fix regression of the default imports in macOS by removing the unused code that caused the misleading fix in #47 (#49)

1.5.6 (2022-04-11)

Features

  • Add the closing_async() async context manager, in addition to aclosing() (#48)

Fixes

  • Allow importing aiotools on Windows platforms, removing incompatible modules from the default __all__ import list (#47)

1.5.5 (2022-03-22)

Features

  • Add wait_timeout option to start_server() (#46)

Fixes

  • Resolve singal races by minimizing expose of event loop in afork()-ed child processes (#46)

Miscellaneous

  • Now the CI runs with Python 3.11a6 or later, with stdlib support of asyncio.TaskGroup (#45)

1.5.4 (2022-03-10)

Features

  • Propagate task results and exceptions via separate future instances if they are await-ed by the caller of create_task() in PersistentTaskGroup, in addition to invocation of task group exception handler. Note that await-ing those futures hangs indefinitely in Python 3.6 but we don't fix it since Python 3.6 is EoL as of December 2021. (#44)

1.5.3 (2022-03-07)

Fixes

  • Fix feature detection for ExceptionGroup and let MultiError inherit ExceptionGroup instead of BaseExceptionGroup (#42)

1.5.2 (2022-03-06)

Fixes

  • Restore the default export of MultiError for backward compatibility (#40)
  • Set current_ptaskgroup only when PersistentTaskGroup is used via the async with statement. (#41)

1.5.1 (2022-03-06)

Fixes

  • Fix missing naming support of TaskGroup in Python 3.11 (#39)

1.5.0 (2022-03-06)

Features

  • Add support for Python 3.9's msg argument to Task.cancel(). (#32)
  • Fix "unexpected cancel" bug in TaskGroup. (#35)
  • Rewrite PersistentTaskGroup to use Python 3.11's latest additions such as Task.uncancel() and Task.cancelling() while still supporting older Python versions (#36)
  • Add PersistentTaskGroup.all() to enumerate all non-terminated persistent task groups (#38)

1.4.0 (2022-01-10)

Features

  • ptaskgroup: Implement PersistentTaskGroup (#30)
  • server: Expose process_index context variable for worker processes (#31)

1.3.0 (2021-12-19)

Fixes

  • Add support for Python 3.10. (#28)

Documentation Changes

  • Fix documentation builds on Python 3.10 and Sphinx 4.x, by removing the 3rd-party autodoc-typehints extension and custom stylesheet overrides. (#28)

1.2.2 (2021-06-07)

Fixes

  • fork: Handle children's segfault (core-dump with signals) explicitly in PidfdChildProcess (#27)

1.2.1 (2021-01-12)

Fixes

  • Avoid side effects of custom clone() function and resorts back to the combinatino of os.fork() and os.pidfd_open() for now (#25)

1.2.0 (2021-01-12)

Breaking Changes

  • server: The use_threading argument for start_server() is completely deprecated. (#23)

Features

  • Now the primary target is Python 3.9, though we still support from Python 3.6 (#22)
  • fork: Add a new module fork to support PID file descriptors in Linux 5.4+ and a POSIX-compatible fallback to asynchornously fork the Python process without signal/PID races. (#22)

Features

  • Add a current_taskgroup context-variable to the taskgroup module (only available for Python 3.7 or later)

Fixes

  • Fix missing auto-import of taskgroup module exports in the aiotools root package.

1.0.0 (2020-10-18)

Features

  • Adopt an implementation of the taskgroup API as aiotools.taskgroup from EdgeDB (#18)
  • Add timer.VirtualClock which provides a virtual clock that makes a block of asyncio codes using asyncio.sleep() to complete instantly and deterministically (#19)
