My Emacs configuration https://git.cjennings.net/dotemacs/atom?h=main 2026-05-24T09:08:19+00:00 2026-05-24T09:08:19+00:00 Craig Jennings c@cjennings.net 2026-05-24T09:08:19+00:00 urn:sha1:556f48a2a0518253015496a618eec9e7a7142dcc Stopping a Wayland recording ran pkill -INT wf-recorder, which signals every wf-recorder on the system — including an unrelated screen capture the user started outside Emacs. The stop path now scopes the producer-first interrupt to the wf-recorder child of our own recording shell via pkill -P <shell-pid>, in the new cj/recording--interrupt-child-wf-recorder helper. The producer-first ordering is unchanged: wf-recorder still gets SIGINT before the process-group signal so ffmpeg sees a clean EOF on pipe:0 and finalizes the MKV. The orphan-cleanup at recording start stays a broad by-name kill on purpose — those leftover recorders come from crashed sessions whose shells are already dead, so there is no live PID to scope to. Tests cover the scoped call, the nil-PID no-op, and that the bare system-wide form is never used.
