[issue29988] with statements are not ensuring that __exit__ is called if __enter__ succeeds

[Nick Coghlan]

Nick Coghlan added the comment:

I've retitled this issue to specifically cover the synchronous signal-safe context management case and filed issue 31387 to cover making it easy to switch asyncio over to cooperative SIGINT handling (rather than the default pre-emptive handling).

title: (async) with blocks and try/finally are not as KeyboardInterrupt-safe as one might like -> with statements are not ensuring that __exit__ is called if __enter__ succeeds
