[dependabot]

Updates the requirements on trio to permit the latest version.

Release notes

Sourced from trio's releases.

v0.26.0

Full Changelog: python-trio/trio@v0.25.1...v0.26.0

Features

• Added an interactive interpreter python -m trio.

  This makes it easier to try things and experiment with trio in the a Python repl. Use the await keyword without needing to call trio.run()

$ python -m trio
Trio 0.26.0, Python 3.10.6
Use "await" directly instead of "trio.run()".
Type "help", "copyright", "credits" or "license" for more information.
>>> import trio
>>> await trio.sleep(1); print("hi")  # prints after one second
hi

See interactive debugging for further detail. (python-trio/trio#2972)

• trio.testing.RaisesGroup can now catch an unwrapped exception with unwrapped=True. This means that the behaviour of except* can be fully replicated in combination with flatten_subgroups=True (formerly strict=False). (python-trio/trio#2989)

Bugfixes

• Fixed a bug where trio.testing.RaisesGroup(..., strict=False) would check the number of exceptions in the raised ExceptionGroup before flattening subgroups, leading to incorrectly failed matches. It now properly supports end ($) regex markers in the match message, by no longer including " (x sub-exceptions)" in the string it matches against. (python-trio/trio#2989)

Deprecations and removals

• Deprecated strict parameter from trio.testing.RaisesGroup, previous functionality of strict=False is now in flatten_subgroups=True. (python-trio/trio#2989)
