one month ago
  • Improved the performance of anyio.Lock and anyio.Semaphore on asyncio (even up to 50 %)
  • Added the fast_acquire parameter to anyio.Lock and anyio.Semaphore to further boost performance at the expense of safety (acquire() will not yield control back if there is no contention)
  • Added support for the from_uri(), full_match(), parser methods/properties in anyio.Path, newly added in Python 3.13 (#737)
  • Added support for more keyword arguments for run_process() and open_process(): startupinfo, creationflags, pass_fds, user, group, extra_groups and umask (#742)
  • Improved the type annotations and support for PathLike in run_process() and open_process() to allow for path-like arguments, just like subprocess.Popen
  • Changed the ResourceWarning from an unclosed memory object stream to include its address for easier identification
  • Changed start_blocking_portal() to always use daemonic threads, to accommodate the "loitering event loop" use case
  • Bumped the minimum version of Trio to v0.26.1
  • Fixed __repr__() of MemoryObjectItemReceiver, when item is not defined (#767; PR by @Danipulok)
  • Fixed to_process.run_sync() failing to initialize if __main__.__file__ pointed to a file in a nonexistent directory (#696)
  • Fixed AssertionError: feed_data after feed_eof on asyncio when a subprocess is closed early, before its output has been read (#490)
  • Fixed TaskInfo.has_pending_cancellation() on asyncio not respecting shielded scopes (#771; PR by @gschaffner)
  • Fixed SocketStream.receive() returning bytearray instead of bytes when using asyncio with ProactorEventLoop (Windows) (#776)
  • Fixed quitting the debugger in a pytest test session while in an active task group failing the test instead of exiting the test session (because the exit exception arrives in an exception group)
  • Fixed support for Linux abstract namespaces in UNIX sockets that was broken in v4.2 (#781 <#781>_; PR by @tapetersen)
  • Fixed KeyboardInterrupt (ctrl+c) hanging the asyncio pytest runner
