A highly opinionated flake8 plugin for Trio-related problems.
This can include anything from outright bugs, to pointless/dead code, to likely performance issues, to minor points of idiom that might signal a misunderstanding.
It may well be too noisy for anyone with different opinions, that's OK.
Pairs well with flake8-async and flake8-bugbear.
pip install flake8-trio- TRIO100: a
with trio.fail_after(...):orwith trio.move_on_after(...):context does not contain anyawaitstatements. This makes it pointless, as the timeout can only be triggered by a checkpoint. - TRIO101
yieldinside a nursery or cancel scope is only safe when implementing a context manager - otherwise, it breaks exception handling. - TRIO102 it's unsafe to await inside
finally:unless you use a shielded cancel scope with a timeout"
