Tyler Goodlet 199ca48cc4 Add `stackscope` tree pprinter triggered by SIGUSR1 ... Can be optionally enabled via a new `enable_stack_on_sig()` which will swap in the SIGUSR1 handler. Much thanks to @oremanj for writing this amazing project, it's thus far helped me fix some very subtle hangs inside our new IPC-context cancellation machinery that would have otherwise taken much more manual pdb-ing and hair pulling XD Full credit for `dump_task_tree()` goes to the original project author with some minor tweaks as was handed to me via the trio-general matrix room B) Slight changes from orig version: - use a `log.pdb()` emission to pprint to console - toss in an ex sh CLI cmd to trigger the dump from another terminal using `kill` + `pgrep`.		2025-03-20 15:07:27 -04:00
