Chore(deps): bump trio from 0.26.2 to 0.27.0

Bumps trio from 0.26.2 to 0.27.0.

Release notes

Sourced from trio's releases.

v0.27.0

Full Changelog: https://github.com/python-trio/trio/compare/v0.26.2...v0.27.0

Breaking changes

• trio.move_on_after and trio.fail_after previously set the deadline relative to initialization time, instead of more intuitively upon entering the context manager. This might change timeouts if a program relied on this behavior. If you want to restore previous behavior you should instead use trio.move_on_at(trio.current_time() + ...). flake8-async has a new rule to catch this, in case you're supporting older trio versions. See ASYNC122. (python-trio/trio#2512)

Features

• CancelScope.relative_deadline and CancelScope.is_relative added, as well as a relative_deadline parameter to __init__. This allows initializing scopes ahead of time, but where the specified relative deadline doesn't count down until the scope is entered. (python-trio/trio#2512)
• trio.Lock and trio.StrictFIFOLock will now raise trio.BrokenResourceError when trio.Lock.acquire would previously stall due to the owner of the lock exiting without releasing the lock. (python-trio/trio#3035)
• trio.move_on_at, trio.move_on_after, trio.fail_at and trio.fail_after now accept shield as a keyword argument. If specified, it provides an initial value for the ~trio.CancelScope.shield attribute of the trio.CancelScope object created by the context manager. (python-trio/trio#3052)
• Added trio.lowlevel.add_parking_lot_breaker and trio.lowlevel.remove_parking_lot_breaker to allow creating custom lock/semaphore implementations that will break their underlying parking lot if a task exits unexpectedly. trio.lowlevel.ParkingLot.break_lot is also added, to allow breaking a parking lot intentionally. (python-trio/trio#3081)

Bugfixes

• Allow sockets to bind any os.PathLike object. (python-trio/trio#3041)
• Update trio.lowlevel.open_process's documentation to allow bytes. (python-trio/trio#3076)
• Update trio.sleep_forever to be NoReturn. (python-trio/trio#3095)

Improved documentation

• Add docstrings for memory channels' statistics() and aclose methods. (python-trio/trio#3101)
