Bumps trio from 0.27.0 to 0.34.0.

Release notes

Sourced from trio's releases.

v0.34.0

Full Changelog: python-trio/trio@v0.33.0...v0.34.0

Features

  • MemoryChannelStatistics now has a peak_buffer_used field, which reports the largest number of items that have ever been in the channel's buffer at once. This makes it easier to pick a sensible max_buffer_size based on data from a real run, instead of guessing. (python-trio/trio#1723)
  • Support Python 3.15, as of beta 4. Things may still change and so this support may break in the future. (python-trio/trio#3456)

Bugfixes

  • Nursery.start() now preserves the __cause__ and __context__ of exceptions raised before task_status.started() is called. (python-trio/trio#3261)
  • Fixed incorrect error message in run_process: the stdout pipe check now correctly says "stdout" instead of "stdin". (python-trio/trio#3409)
  • Fixed trio.Path.as_uri() on Python 3.14+ to avoid the deprecated pathlib.PurePath.as_uri() path. (python-trio/trio#3460)
  • Fixed trio.to_thread.run_sync workers leaking spawner's Context on py314t+ free-threaded builds. (python-trio/trio#3472)

Deprecations and removals

  • Trying to use absolute deadlines on a trio.CancelScope constructed with a relative deadline now raises, after being deprecated since Trio 0.27.0.

    To switch a cancel scope from being relative to absolute, replace the trio.CancelScope object instead of trying to mutate it. (python-trio/trio#3403)

v0.33.0

Full Changelog: python-trio/trio@v0.32.0...v0.33.0

Bugfixes

Deprecations and removals

  • Both trio.testing.RaisesGroup and trio.testing.Matcher have been deprecated. Pytest alternatives pytest.RaisesGroup and pytest.RaisesExc (respectively) are considered correct replacement. (python-trio/trio#3326)

v0.32.0

Full Changelog: python-trio/trio@v0.31.0...v0.32.0

Bugfixes

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
