* [3.13] gh-133745: Fix asyncio task factory name/context kwarg breaks (#133948)Thomas Grainger2025-05-181-5/+11
| | | | | | | | | In 3.13.3 we accidentally broke the interface for custom task factory. Factory authors added workarounds. This PR (for 3.13.4) unbreaks task factories that haven't made a workaround yet while also supporting those that have. NOTE: The custom task factory API will change to what we accidentally released in 3.13.3. Co-authored-by: Kumar Aditya <kumaraditya@python.org> Co-authored-by: Guido van Rossum <gvanrossum@gmail.com>

* [3.13] gh-87744: fix waitpid race while calling send_signal in asyncio ↵Miss Islington (bot)2024-07-011-9/+26
| | | | | | | | | | | (GH-121126) (#121194) gh-87744: fix waitpid race while calling send_signal in asyncio (GH-121126) asyncio earlier relied on subprocess module to send signals to the process, this has some drawbacks one being that subprocess module unnecessarily calls waitpid on child processes and hence it races with asyncio implementation which internally uses child watchers. To mitigate this, now asyncio sends signals directly to the process without going through the subprocess on non windows systems. On Windows it fallbacks to subprocess module handling but on windows there are no child watchers so this issue doesn't exists altogether.

* gh-117722: Fix Stream.readuntil with non-bytes buffer objects (#117723)Bruce Merry2024-04-111-5/+5
| | | | | | | | | | | | | gh-16429 introduced support for an iterable of separators in Stream.readuntil. Since bytes-like types are themselves iterable, this can introduce ambiguities in deciding whether the argument is an iterator of separators or a singleton separator. In gh-16429, only 'bytes' was considered a singleton, but this will break code that passes other buffer object types. Fix it by only supporting tuples rather than arbitrary iterables. Closes gh-117722.
* gh-116720: Fix corner cases of taskgroups (#117407)Guido van Rossum2024-04-092-6/+15

This prevents us from doing automatical cleanup, and complaining that the StreamWriter wasn't properly closed. Fortunately, the extra reference was never actually used for anything so we can just drop it.
