# Keeps the Mac mini's Horizon runners from filling its disk. launchd runs a copy taken from main
|
|
# (~/.actions-runners/runner-gc.sh, never a pull request's checkout) every 6 hours; see docs/release-flow.md.
|
|
# - A runner in the middle of a job is left alone.
|
|
# - A checkout whose cargo build folders (target/ and the harness probes' targets under .local/, the
|
|
# directories holding a CACHEDIR.TAG) pass MAX_TARGET_GB loses them: sccache (tools/ci/runner-env.sh)
|
|
# makes the next build cheap. Symlinks into the shared vanilla data are never followed.
|
|
# - Harness work folders under .local/ (vanilla exports, probe outputs: real directories, not the links into
|
|
# the shared vanilla data) that nothing touched for STALE_DAYS go; a harness that runs again rebuilds its own.
|
|
# .local/parity-runner (run state, oracle cache) stays.
|
|
# - The shared prepared resources keep their KEEP_PREPARED newest preparations, only while no runner works.
|
|
# - Java processes harnesses left behind (vanilla servers, oracles) go once ORPHAN_HOURS old: those whose parent
|
|
# is gone (adopted by launchd, init or systemd --user) and whose command line names a runner's checkout or a
|
|
# worktree's .local/. A job cancelled while it ran left such servers for days (2026-10-26); tools/parity.py now
|
|
# stops its harnesses on SIGTERM, and this catches what it can't (SIGKILL, a harness run by hand).
