## Summary
|
||
|
|
|
||
|
|
A practical how-to article confirming the terminate()-then-kill() escalation pattern specifically for `asyncio` subprocesses (as opposed to the synchronous `subprocess` module, which several other sources in this subject focus on).
|
||
|
|
|
||
|
|
## Key findings
|
||
|
|
|
||
|
|
- Confirms the same two-stage (SIGTERM, then SIGKILL after a grace period) escalation pattern applies directly to `asyncio.subprocess.Process`, not just the synchronous `subprocess.Popen`.
|
||
|
|
|
||
|
|
## Pros / strengths
|
||
|
|
|
||
|
|
- Asyncio-specific confirmation, closing a small gap left by sources that primarily discuss the synchronous `subprocess` module.
|
||
|
|
|
||
|
|
## Cons / limitations / caveats
|
||
|
|
|
||
|
|
- A how-to-style article without deep discussion of process groups or zombie-reaping; those details came from other sources in this subject (`iannuccisolutions-timeout-process-group.md`, `alexandra-zaharia-kill-subprocess-children-timeout.md`).
|
||
|
|
|
||
|
|
## Relevance to tai
|
||
|
|
|
||
|
|
One more confirming data point that `ManagedProcess.terminate()`'s SIGTERM-then-SIGKILL escalation is correct for the asyncio subprocess API specifically, not just a synchronous-API pattern being assumed to transfer.
