/jira cherrypick OCPBUGS-120722

…cleanup Both pkg/helm/actions and pkg/helm/chartproxy start chartmuseum processes independently. The stop scripts used `pkill -15 chartmuseum` which kills ALL chartmuseum processes system-wide. When `go test ./...` runs these packages in parallel, one package's cleanup can kill the other's chartmuseum mid-startup, causing a panic. Replace global pkill with PID-file based kills (matching the pattern already used by zot stop scripts): - actions: write PID files for all three chartmuseum variants (TLS, no-TLS, basic-auth) and kill by PID in stop script - chartproxy: convert start script to exec pattern with PID file, kill by PID in stop script - cleanup scripts: remove PID files alongside other artifacts - diagnostics: check all PID files on timeout, not just TLS Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Validate PID values before passing to kill to prevent unintended arguments from malformed PID files. Check PID file writes succeed before exec to ensure stop scripts can terminate the process. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

OCPBUGS-115318 kill -TERM 0 sends the signal to the entire process group rather than a single process. Tighten the PID regex from ^[0-9]+$ to ^[1-9][0-9]*$ so that a zero value is treated as invalid. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

OCPBUGS-115318 Before sending SIGTERM, check that the PID from the PID file still belongs to a chartmuseum process using ps. This prevents stale PID files from accidentally terminating unrelated processes. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Hi @platex-rehor-bot. Thanks for your PR.

I'm waiting for a openshift member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Tip

We noticed you've done this a few times! Consider joining the org to skip this step and gain /lgtm and other bot rights. We recommend asking approvers on your previous PRs to sponsor you.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
