Changelog for python38-trio-0.21.0-1.4.noarch.rpm :

* Sun Sep 25 2022 Dirk Müller - update to 0.21.0:
* Trio now supports Python 3.11.
* Remove support for Python 3.6.
* Tue Mar 29 2022 Ben Greiner - Update to version 0.20.0
* You can now conveniently spawn a child process in a background task and interact it with on the fly using process = await nursery.start(run_process, ...). See run_process for more details. We recommend most users switch to this new API. Also note that: - trio.open_process has been deprecated in favor of trio.lowlevel.open_process, - The aclose method on Process has been deprecated along with async with process_obj. (#1104)
* Now context variables set with contextvars are preserved when running functions in a worker thread with trio.to_thread.run_sync, or when running functions from the worker thread in the parent Trio thread with trio.from_thread.run, and trio.from_thread.run_sync. This is done by automatically copying the contextvars context. trio.lowlevel.spawn_system_task now also receives an optional context argument. (#2160)
* Trio now avoids creating cyclic garbage when a MultiError is generated and filtered, including invisibly within the cancellation system. This means errors raised through nurseries and cancel scopes should result in less GC latency. (#2063)
* Trio now deterministically cleans up file descriptors that were opened before subprocess creation fails. Previously, they would remain open until the next run of the garbage collector. (#2193)
* Add compatibility with OpenSSL 3.0 on newer Python and PyPy versions by working around SSLEOFError not being raised properly. (#2203)
* Fix a bug that could cause Process.wait to hang on Linux systems using pidfds, if another task were to access Process.returncode after the process exited but before wait woke up (#2209)- Drop trio-pr2043-py310ssl-deprecationwarnings.patch
* Sun Dec 12 2021 Ben Greiner - Update to version 0.19.0
* Trio now supports Python 3.10. (#1921)
* Use slots for `~.lowlevel.Task` which should make them slightly smaller and faster. (#1927)
* Make `~.Event` more lightweight by using less objects (about 2 rather than 5, including a nested ParkingLot and attribute dicts) and simpler structures (set rather than OrderedDict). This may benefit applications that create a large number of event instances, such as with the \"replace event object on every set()\" idiom. (#1948)
* The event loop now holds on to references of coroutine frames for only the minimum necessary period of time. (#1864)
* The `~.lowlevel.TrioToken` class can now be used as a target of a weak reference. (#1924)- Release 0.18.0
* Add synchronous .close() methods and context manager (with x) support for .MemorySendChannel and .MemoryReceiveChannel. (#1797)
* Previously, on Windows, Trio programs using thousands of sockets at the same time could trigger extreme slowdowns in the Windows kernel. Now, Trio works around this issue, so you should be able to use as many sockets as you want. (#1280)
* `trio.from_thread.run` no longer crashes the Trio run if it is executed after the system nursery has been closed but before the run has finished. Calls made at this time will now raise trio.RunFinishedError. This fixes a regression introduced in Trio 0.17.0. The window in question is only one scheduler tick long in most cases, but may be longer if async generators need to be cleaned up. (#1738)
* Fix a crash in pypy-3.7 (#1765)
* Trio now avoids creating cyclic garbage as often. This should have a minimal impact on most programs, but can slightly reduce how often the cycle collector GC runs on CPython, which can reduce latency spikes. (#1770)
* Remove deprecated max_refill_bytes from `SSLStream`. (#959)
* Remove the deprecated tiebreaker argument to trio.testing.wait_all_tasks_blocked. (#1558)
* Remove the deprecated trio.hazmat module. (#1722)
* Stop allowing subclassing public classes. This behavior was deprecated in 0.15.0. (#1726)- Add trio-pr2043-py310ssl-deprecationwarnings.patch
* Fri Jan 08 2021 Markéta Machová - Skip test incompatible with new pytest 6.2
* Sun Oct 11 2020 John Vandenberg - Remove hashbang and tests in runtime package- Disable test test_close_at_bad_time_for_send_all due to failure on PPC- Update to v0.17.0
* trio.open_tcp_stream has a new local_address= keyword argument that can be used on machines with multiple IP addresses to control which IP is used for the outgoing connection
* If you pass a raw IP address into sendto, it no longer spends any time trying to resolve the hostname. If you\'re using UDP, this should substantially reduce your per-packet overhead
* trio.lowlevel.checkpoint is now much faster
* new, lower-overhead data structure to track upcoming timeouts, which should make your programs faster
* Trio can now be imported when sys.excepthook is a functools.partial instance, which might occur in a pytest-qt test function
* The thread cache didn\'t release its reference to the previous job
* Remove wait_socket_
*, notify_socket_closing, notify_fd_closing, run_sync_in_worker_thread and current_default_worker_thread_limiter
* When using \"instruments\", you now only \"pay for what you use\": if there are no instruments installed that override a particular hook such as `abc.Instrument.before_task_step`, then Trio doesn\'t waste any effort on checking its instruments when the event corresponding to that hook occurs.
* Thu Jul 23 2020 Marketa Calabkova - Update to 0.16.0
* If you want to use Trio, but are stuck with some other event loop like Qt or PyGame, then good news: now you can have both.
* To speed up `trio.to_thread.run_sync`, Trio now caches and re-uses worker threads.
* Tasks spawned with `nursery.start() ` aren\'t treated as direct children of their nursery until they call ``task_status.started()``.
* Some bugfixes and deprecations
* Tue Jun 09 2020 Tomáš Chvátal - Update to 0.15.1:
* Added a helpful error message if an async function is passed to trio.from_thread.run_sync or a sync function to trio.from_thread.run. (#1244)
* Previously, when trio.run_process was cancelled, it always killed the subprocess immediately. Now, on Unix, it first gives the process a chance to clean up by sending SIGTERM, and only escalates to SIGKILL if the process is still running after 5 seconds. But if you prefer the old behavior, or want to adjust the timeout, then don\'t worry: you can now pass a custom deliver_cancel= argument to define your own process killing policy. (#1104)
* It turns out that creating a subprocess can block the parent process for a surprisingly long time. So trio.open_process now uses a worker thread to avoid blocking the event loop. (#1109)
* On Linux kernels v5.3 or newer, trio.Process.wait now uses the pidfd API to track child processes. This shouldn\'t have any user-visible change, but it makes working with subprocesses faster and use less memory. (#1241)
* The trio.Process.returncode attribute is now automatically updated as needed, instead of only when you call ~trio.Process.poll or ~trio.Process.wait. Also, repr(process_object) now always contains up-to-date information about the process status. (#1315)
* Sat Jan 11 2020 Ondřej Súkup - update to 0.13.0
* Use slots for memory channel state and statistics which should make memory channels slightly smaller and faster.
* OpenSSL has a bug in its handling of TLS 1.3 session tickets that can cause deadlocks or data loss in some rare edge cases. These edge cases most frequently happen during tests.
* Trio now uses signal.set_wakeup_fd on all platforms.
* Trio no longer crashes when an async function is implemented in C or Cython and then passed directly to trio.run or nursery.start_soon.
* When a Trio task makes improper use of a non-Trio async library, Trio nowi causes an exception to be raised within the task at the point of the error, rather than abandoning the task and raising an error in its parent. This improves debuggability and resolves the TrioInternalError that would sometimes result from the old strategy. (#552)
* In 0.12.0 we deprecated trio.run_sync_in_worker_thread in favor of trio.to_thread.run_sync. But, the deprecation message listed the wrong name for the replacement.
* Fix regression introduced with cancellation changes in 0.12.0, where a trio.CancelScope which isn\'t cancelled could catch a propagating trio.Cancelled exception if shielding were changed while the cancellation was propagating.
* Fix a crash that could happen when using MockClock with autojump enabled and a non-zero rate.
* If you nest >1000 cancel scopes within each other, Trio now handles that gracefully instead of crashing with a RecursionError.
* Fixed the hash behavior of trio.Path to match pathlib.Path. Previously trio.Path\'s hash was inherited from object instead of from pathlib.PurePath.
* Mon Aug 05 2019 pgajdosAATTsuse.com- version update to 0.12.1 Features
* If you have a `~trio.abc.ReceiveStream` object, you can now use ``async for data in stream: ...`` instead of calling `~trio.abc.ReceiveStream.receive_some`. Each iteration gives an arbitrary sized chunk of bytes. And the best part is, the loop automatically exits when you reach EOF, so you don\'t have to check for it yourself anymore. Relatedly, you no longer need to pick a magic buffer size value before calling `~trio.abc.ReceiveStream.receive_some`; you can ``await stream.receive_some()`` with no arguments, and the stream will automatically pick a reasonable size for you. (`#959 `__)
* Threading interfaces have been reworked: ``run_sync_in_worker_thread`` is now `trio.to_thread.run_sync`, and instead of ``BlockingTrioPortal``, use `trio.from_thread.run` and `trio.from_thread.run_sync`. What\'s neat about this is that these cooperate, so if you\'re in a thread created by `to_thread.run_sync`, it remembers which Trio created it, and you can call ``trio.from_thread.
*`` directly without having to pass around a ``BlockingTrioPortal`` object everywhere. (`#810 `__)
* We cleaned up the distinction between the \"abstract channel interface\" and the \"memory channel\" concrete implementation. `trio.abc.SendChannel` and `trio.abc.ReceiveChannel` have been slimmed down, `trio.MemorySendChannel` and `trio.MemoryReceiveChannel` are now public types that can be used in type hints, and there\'s a new `trio.abc.Channel` interface for future bidirectional channels. (`#719 `__)
* Add :func:`trio.run_process` as a high-level helper for running a process and waiting for it to finish, like the standard :func:`subprocess.run` does. (`#822 `__)
* On Linux, when wrapping a bare file descriptor in a Trio socket object, Trio now auto-detects the correct ``family``, ``type``, and ``protocol``. This is useful, for example, when implementing `systemd socket activation `__. (`#251 `__)
* Trio sockets have a new method `~trio.socket.SocketType.is_readable` that allows you to check whether a socket is readable. This is useful for HTTP/1.1 clients. (`#760 `__)
* We no longer use runtime code generation to dispatch core functions like `current_time`. Static analysis tools like mypy and pylint should now be able to recognize and analyze all of Trio\'s top-level functions (though some class attributes are still dynamic... we\'re working on it). (`#805 `__)
* Add `trio.hazmat.FdStream` for wrapping a Unix file descriptor as a `~trio.abc.Stream`. (`#829 `__)
* Trio now gives a reasonable traceback and error message in most cases when its invariants surrounding cancel scope nesting have been violated. (One common source of such violations is an async generator that yields within a cancel scope.) The previous behavior was an inscrutable chain of TrioInternalErrors. (`#882 `__)
* MultiError now defines its ``exceptions`` attribute in ``__init__()`` to better support linters and code autocompletion. (`#1066 `__)
* Use ``__slots__`` in more places internally, which should make Trio slightly faster. (`#984 `__)
* In v0.12.0, we accidentally moved ``BlockingTrioPortal`` from ``trio`` to ``trio.hazmat``. It\'s now been restored to its proper position. (It\'s still deprecated though, and will issue a warning if you use it.) (`#1167 `__) Bugfixes
* Destructor methods (``__del__``) are now protected against ``KeyboardInterrupt``. (`#676 `__)
* The :class:`trio.Path` methods :meth:`~trio.Path.glob` and :meth:`~trio.Path.rglob` now return iterables of :class:`trio.Path` (not :class:`pathlib.Path`). (`#917 `__)
* Inspecting the :attr:`~trio.CancelScope.cancel_called` attribute of a not-yet-exited cancel scope whose deadline is in the past now always returns ``True``, like you might expect. (Previously it would return ``False`` for not-yet-entered cancel scopes, and for active cancel scopes until the first checkpoint after their deadline expiry.) (`#958 `__)
* The :class:`trio.Path` classmethods, :meth:`~trio.Path.home` and :meth:`~trio.Path.cwd`, are now async functions. Previously, a bug in the forwarding logic meant :meth:`~trio.Path.cwd` was synchronous and :meth:`~trio.Path.home` didn\'t work at all. (`#960 `__)
* An exception encapsulated within a :class:`MultiError` doesn\'t need to be hashable anymore.
