Ports the bounded retry+backoff around each `git clone` in scripts/clone-manifest.sh onto main, mirroring PR #298 which landed the same change on staging. CI-infra carve-out: publish-workspace-server-image.yml fires on `push: branches:[main]`, so the retry mitigation must be on main for the workflow to be resilient to the OOM-killed-git-mid-clone flake (`error: git-remote-https died of signal 9`, run 4622) when triggered by a main push. Same one-file change as #298 (+45/-5), POSIX-sh, sh -n clean. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

# clone-manifest.sh — clone all repos listed in manifest.json into their
|
|
# target directories. Replaces hardcoded git-clone lines in Dockerfiles.
|
|
#
|
|
# Usage:
|
|
# ./scripts/clone-manifest.sh <manifest.json> <ws-templates-dir> <org-templates-dir> <plugins-dir>
|
|
#
|
|
# Requires: git, jq (lighter than python3 — ~2MB vs ~50MB in Alpine)
|
|
#
|
|
# Auth (optional):
|
|
# Post-2026-05-08 (#192): every repo in manifest.json is public on
|
|
# git.moleculesai.app. Anonymous clone works for the entire registered
|
|
# set. The OSS-surface contract is recorded in manifest.json's _comment
|
|
# — Layer-3 customer/private templates (e.g. reno-stars) are NOT in the
|
|
# manifest; they are handled at provision-time via the per-tenant
|
|
# credential resolver (internal#102 RFC).
|
|
#
|
|
# MOLECULE_GITEA_TOKEN is therefore optional today. Kept supported for
|
|
# two reasons: (a) historical CI configs that still inject
|
|
# AUTO_SYNC_TOKEN remain harmless, (b) reserved for the case where a
|
|
# private internal-only template is later registered via a ci-readonly
|
|
# team grant — review must explicitly sign off on that, since it
|
|
# violates the public-OSS-surface contract.
|
|
#
|
|
# The token (when set) never enters the Docker image: this script runs
|
|
# in the trusted CI context BEFORE `docker buildx build`, populates
|
|
# .tenant-bundle-deps/, then `Dockerfile.tenant` COPYs from there with
|
|
# the .git directories already stripped (see line ~67 below).

# clone_one_with_retry — clone a single repo, retrying on transient failure.
|
|
#
|
|
# Why: the publish-workspace-server-image (and harness-replays) CI jobs
|
|
# clone the full manifest (~36 repos) serially on a memory-constrained
|
|
# Gitea Actions runner. Under host memory pressure the OOM killer
|
|
# occasionally SIGKILLs git-remote-https mid-clone:
|
|
#
|
|
# error: git-remote-https died of signal 9
|
|
# fatal: the remote end hung up unexpectedly
|
|
#
|
|
# (observed in publish-workspace-server-image run 4622 on 2026-05-10 — the
|
|
# job died on the 14th of 36 clones, which wedged staging→main). One
|
|
# transient SIGKILL / network blip would otherwise fail the whole tenant
|
|
# image rebuild. Retrying after a short backoff lets the pressure subside.
|
|
# The durable fix is more runner RAM/swap (tracked with Infra-SRE); this
|
|
# just stops a single flake from being release-blocking.
