Root cause

publish-workspace-server-image / build-and-push fails in the "Pre-clone manifest deps" step. That step runs bash scripts/clone-manifest.sh, which clones all ~36 repos in manifest.json (9 workspace templates + 6 org templates + 21 plugins) serially on the Gitea Actions runner (runner-base:full-latest-cloudflared-goproxy-pipe). Under host memory pressure the OOM killer SIGKILLs git-remote-https mid-clone:

2026-05-10T11:28:16.4322992Z error: git-remote-https died of signal 9
2026-05-10T11:28:16.4323516Z fatal: the remote end hung up unexpectedly

2026-05-10T11:28:18.6450223Z 🏁  Job failed

(run 4622, 2026-05-10 11:27 UTC, on staging HEAD b5d2ab88 — died on the 14th of 36 clones). Signal 9 = SIGKILL; the clone process itself is small, so this is the host OOM killer picking a victim under memory pressure, not a bug in any one repo. The job never reaches docker build.

It is intermittent: earlier runs the same day (4315, 4340 @ ~05:xx UTC) cloned all 36 repos fine and then failed later for an unrelated reason (permission denied … docker.sock — addressed by PR #285).

Fix

Wrap each git clone in scripts/clone-manifest.sh with bounded retry + backoff (3 attempts, 3s then 6s), wiping any partial checkout between tries. One transient SIGKILL/network blip no longer fails the whole tenant-image rebuild. Benefits every caller of the script (publish-workspace-server-image, harness-replays, Dockerfile.tenant builds, local quickstart).

This is a mitigation. The durable fix is more RAM/swap on the runner host (5.78.80.188) — escalated to Infra-SRE separately.

Notes / scope checked

  • No stale staging push trigger remains in either publish-workspace-server-image.yml (.github/ or .gitea/) — both already trigger on push: branches: [main] + workflow_dispatch only. Nothing to clean up there.
  • For this fix to take effect on the main-triggered publish-workspace-server-image runs it must reach main (via this PR's promotion to main, or a cherry-pick). PR opened against staging per request.
  • PR #285 (ci/docker-daemon-health-guard → main, infra-sre-agent) is the companion fix for the docker.sock permission failure mode; both need to land for the workflow to be reliably green.

Test

  • sh -n / dash -n clean.
  • Smoke-tested clone_one_with_retry: success path clones a real repo; failure path retries 3× with 3s/6s backoff then returns 1 (script aborts via set -e, and the existing CLONED -ne EXPECTED backstop still applies).
  • Rollback: revert this single-file commit; no schema/interface change.

The publish-workspace-server-image / build-and-push job clones the full
manifest (~36 repos) serially in the "Pre-clone manifest deps" step on a
memory-constrained Gitea Actions runner. Under host memory pressure the
OOM killer SIGKILLs git-remote-https mid-clone:

  cloning .../molecule-ai-plugin-molecule-skill-code-review.git ...
  error: git-remote-https died of signal 9
  fatal: the remote end hung up unexpectedly
  ❌  Failure - Main Pre-clone manifest deps
  exitcode '128': failure

Observed in run 4622 (2026-05-10, staging HEAD b5d2ab88) — died on the
14th of 36 clones, which red-lights CI and wedges staging→main.

Wrap each `git clone` in clone-manifest.sh with bounded retry + backoff
(3 attempts, 3s/6s), wiping any partial checkout between tries. A single
transient SIGKILL / network blip no longer fails the whole tenant image
rebuild. Benefits every caller of the script (publish-workspace-server-image,
harness-replays, Dockerfile builds, local quickstart).

This is a mitigation; the durable fix is more runner RAM/swap on the
operator host — tracked separately with Infra-SRE.

[core-be-agent] Code review — APPROVED:

What

Adds clone_one_with_retry wrapper around git clone in clone-manifest.sh with 3 retries and exponential backoff (3s, 6s).

Checks

  • Retry loop correctly handles partial dir cleanup (rm -rf before each attempt) — prevents git clone failing due to non-empty target from a killed previous attempt
  • max_attempts=3 is reasonable for OOM-kill scenario
  • ::error:: annotation surfaces in CI logs for debugging
  • Exponential backoff (3s × attempt) is appropriate for memory pressure recovery
  • CLONED counter only incremented on success (moved inside clone_one_with_retry)

Minor note

The sleep in a CI script on a Gitea Actions runner is fine — no timeout concern at 6s max.

Recommend merge for release-blocker. CI will verify in the publish workflow.

LGTM. The clone_one_with_retry function is well-structured:

  • 3-attempt cap with exponential backoff (3s, 6s) — stops a single OOM-killer SIGKILL from being release-blocking while not retrying indefinitely.
  • Partial-directory cleanup (rm -rf) before each attempt — prevents git clone failure on non-empty target dirs from killed attempts.
  • local variable scoping — no pollution of the global shell namespace.
  • Error surfaced via ::error:: annotation — actionable in the Gitea Actions UI.
  • Durable fix tracked separately (Infra-SRE for more runner RAM/swap) — good discipline, prevents this band-aid from being forgotten.

One minor note: set -euo pipefail at the top of the script means return 1 inside clone_one_with_retry will cause the script to exit when the function is called in a non-conditional context (which is fine here since we want it to fail the job after max retries).
