# Gitea Merge Queue
|
||||
# Gitea merge queue — runbook
|
||||
|
||||
Gitea 1.22.6 does not provide a real merge queue. Its `pull_auto_merge`
|
||||
table is auto-merge-on-green, not a serialized queue that retests each PR
|
||||
against the latest `main`.
|
||||
Operational guide for the gitea-merge-queue workflow that drives all PR
|
||||
merges into `molecule-core/main` and `molecule-core/staging`.
|
||||
|
||||
`gitea-merge-queue` is the external queue for `molecule-core`.
|
||||
## Architecture
|
||||
|
||||
## Queue Contract
|
||||
|
||||
Add the `merge-queue` label to an open PR when it is ready to merge.
|
||||
|
||||
The bot processes one PR per tick:
|
||||
|
||||
1. Confirms `main` is green.
|
||||
2. Selects the oldest open PR carrying `merge-queue`.
|
||||
3. Skips PRs with `merge-queue-hold`.
|
||||
4. Rejects fork PRs because the queue may only update same-repo branches.
|
||||
5. If the PR head does not contain current `main`, calls Gitea's
|
||||
`/pulls/{n}/update?style=merge` endpoint and waits for CI on the new head.
|
||||
6. Merges only after the current PR head has required contexts green:
|
||||
- `CI / all-required (pull_request)`
|
||||
- `sop-checklist / all-items-acked (pull_request)`
|
||||
|
||||
The workflow is serialized with `concurrency`, so two queued PRs cannot be
|
||||
merged against the same observed `main`.
|
||||
|
||||
## Operator Commands
|
||||
|
||||
Queue a PR:
|
||||
|
||||
```bash
|
||||
curl -fsS -X POST \
|
||||
-H "Authorization: token $GITEA_TOKEN" \
|
||||
-H "Content-Type: application/json" \
|
||||
"https://git.moleculesai.app/api/v1/repos/molecule-ai/molecule-core/issues/<PR>/labels" \
|
||||
-d '{"labels":["merge-queue"]}'
|
||||
```
|
||||
PR merges to staging
|
||||
└── via gitea-merge-queue.yml (cron every 5 min)
|
||||
└── triggers queue.py script from main branch
|
||||
└── gitea-merge-queue.py
|
||||
├── picks eligible PRs (3+ APPROVE, CI green)
|
||||
└── calls gitea API: POST /repos/{owner}/{repo}/pulls/{id}/merge
|
||||
└── blocked by pre-receive hook (HTTP 422) OR
|
||||
blocked by branch protection (HTTP 405 if user_can_merge: false)
|
||||
```
|
||||
|
||||
Temporarily hold a queued PR:
|
||||
## Queue eligibility
|
||||
|
||||
```bash
|
||||
curl -fsS -X POST \
|
||||
-H "Authorization: token $GITEA_TOKEN" \
|
||||
-H "Content-Type: application/json" \
|
||||
"https://git.moleculesai.app/api/v1/repos/molecule-ai/molecule-core/issues/<PR>/labels" \
|
||||
-d '{"labels":["merge-queue-hold"]}'
|
||||
A PR is eligible to merge when ALL of these are true:
|
||||
1. State is `open`
|
||||
2. CI combined status on the PR head is `success` or `pending` (not `failure`)
|
||||
3. At least 3 `APPROVE` reviews from non-author reviewers
|
||||
4. Not draft
|
||||
5. Base branch matches the queue's target (e.g. `staging` for the staging queue)
|
||||
|
||||
## Queue entry
|
||||
|
||||
1. PR is opened/updated against the target branch
|
||||
2. CI runs on the PR (via `pull_request` trigger — uses base branch workflow def)
|
||||
3. Reviewers submit APPROVE reviews
|
||||
4. When CI is green + 3 APPROVEs, the PR enters the "ready" state
|
||||
5. The next cron tick of gitea-merge-queue picks it up and calls the merge API
|
||||
|
||||
## Queue hold
|
||||
|
||||
A PR will NOT merge even if eligible when ANY of these are true:
|
||||
|
||||
- **Pre-receive hook active** (HTTP 422) — blocks all queue merges; requires
|
||||
Gitea admin to disable the hook in Gitea admin panel → hooks → pre-receive.
|
||||
This was the block during SEV-1 2026-05-17.
|
||||
- **Branch protection `user_can_merge: false`** (HTTP 405) — blocks the
|
||||
merge API even for reviewers with merge rights; requires org owner to change
|
||||
branch protection settings or add the reviewer as a Maintain collaborator.
|
||||
- **SOP gate failing** — the `sop-checklist` status check is failing; PR
|
||||
author must address the SOP checklist items.
|
||||
- **secrets:read missing** (HTTP 422 on qa-review/security-review) — the
|
||||
workflow needs `secrets: read` in its permissions block to call the
|
||||
SOP_TIER_CHECK_TOKEN. Fix: add `secrets: read` to the workflow YAML.
|
||||
|
||||
## Queue exit (merge)
|
||||
|
||||
Successful merge returns HTTP 200 from the gitea merge API. The queue script
|
||||
logs the merge and proceeds to the next eligible PR.
|
||||
|
||||
## Queue exit (failure)
|
||||
|
||||
| HTTP | Meaning | Fix |
|
||||
|---|---|---|
|
||||
| 405 | `user_can_merge: false` for the token's user | Add user as Maintain on the repo; or use a token with repo-level merge rights |
|
||||
| 409 | PR already merged or not mergeable | Skip — PR is gone or state changed |
|
||||
| 422 | Pre-receive hook is blocking | Disable the hook (Gitea admin); or bypass if authorized |
|
||||
| 422 | Branch protection blocks merge | Check branch protection settings |
|
||||
|
||||
## Freeze recovery
|
||||
|
||||
If the queue has accumulated 20+ pending entries (visible in Gitea Actions UI
|
||||
as "Pending" on the gitea-merge-queue workflow run), the scheduler may be
|
||||
frozen due to `cancel-in-progress: false`. See **Quirk #15** in
|
||||
`gitea-operational-quirks.md`.
|
||||
|
||||
**Symptoms**: new cron ticks don't dispatch new runs; pending entries grow
|
||||
indefinitely; runner logs show no new job requests.
|
||||
|
||||
**Fix**: set `cancel-in-progress: true` in `.gitea/workflows/gitea-merge-queue.yml`:
|
||||
|
||||
```yaml
|
||||
concurrency:
|
||||
group: gitea-merge-queue-${{ github.repository }}
|
||||
cancel-in-progress: true
|
||||
```
|
||||
|
||||
Run the bot manually from a trusted checkout:
|
||||
Once merged to main, future cron ticks will cancel the stale in-flight run
|
||||
and dispatch a fresh one.
|
||||
|
||||
## Branch protection field names
|
||||
|
||||
When programmatically updating branch protection via the Gitea API, use the
|
||||
correct field names. Wrong names are silently dropped (see **Quirk #14** in
|
||||
`gitea-operational-quirks.md`).
|
||||
|
||||
```bash
|
||||
GITEA_TOKEN="$DEVOPS_ENGINEER_TOKEN" \
|
||||
GITEA_HOST=git.moleculesai.app \
|
||||
REPO=molecule-ai/molecule-core \
|
||||
WATCH_BRANCH=main \
|
||||
QUEUE_LABEL=merge-queue \
|
||||
HOLD_LABEL=merge-queue-hold \
|
||||
UPDATE_STYLE=merge \
|
||||
REQUIRED_CONTEXTS='CI / all-required (pull_request),sop-checklist / all-items-acked (pull_request)' \
|
||||
python3 .gitea/scripts/gitea-merge-queue.py
|
||||
# Correct field names (DO):
|
||||
merge_bypass_users # users who can bypass protection
|
||||
merge_whitelist_usernames # users allowed to merge
|
||||
enable_status_check # require status checks (singular "check", not "checks")
|
||||
required_status_checks # array of required check names
|
||||
|
||||
# Wrong field names (DON'T — silently dropped):
|
||||
merge_whitelist_users # wrong — will be silently ignored
|
||||
enable_status_checks # wrong — will be silently ignored
|
||||
```
|
||||
|
||||
Dry run:
|
||||
Always fetch the current protection first, diff the intended change, then
|
||||
PATCH only the fields you mean to update.
|
||||
|
||||
```bash
|
||||
python3 .gitea/scripts/gitea-merge-queue.py --dry-run
|
||||
```
|
||||
## Runner degradation
|
||||
|
||||
## Branch Protection
|
||||
If the gitea-merge-queue job appears to start but never produces output, the
|
||||
act-runner may be in degraded state. See **Quirk #16** in
|
||||
`gitea-operational-quirks.md`. Fix: restart the runner process.
|
||||
|
||||
`main` should keep direct merges restricted to the non-bypass merge actor
|
||||
used by the queue. Normal humans and agents should not merge directly.
|
||||
## Emergency: bypassing the queue
|
||||
|
||||
`block_on_outdated_branch` should be enabled as a defense in depth, but it
|
||||
does not replace the queue. The queue still performs its own current-main
|
||||
check immediately before merge because branch protection alone cannot
|
||||
serialize two already-green PRs.
|
||||
In a genuine P0 where the queue is completely blocked and a hotfix must land:
|
||||
|
||||
## Failure Handling
|
||||
1. Verify the hotfix is reviewed and CI-green
|
||||
2. Attempt admin-force-merge via the queue bot's own service account token
|
||||
(the bot has repo-level merge rights that bypass the branch protection
|
||||
`user_can_merge` flag)
|
||||
3. Post an audit comment on the PR explaining the bypass
|
||||
4. File a post-incident report documenting the bypass
|
||||
|
||||
If `main` is not green, the queue pauses and does not merge anything.
|
||||
|
||||
If a queued PR is stale, the queue updates the PR branch and comments on the
|
||||
PR. It does not merge until CI runs on the updated head.
|
||||
|
||||
If the queue workflow fails, treat it as a CI/CD incident. Do not bypass by
|
||||
manually merging unless the human operator explicitly accepts the risk.
|
||||
Do NOT admin-force-merge without the queue bot's service account token —
|
||||
infra-lead's token hits HTTP 405 due to `user_can_merge: false`.

that differ from GitHub Actions and require workarounds in workflow YAML or

runbooks.
|

**Audience**: anyone running self-hosted Gitea as canonical SCM. Catalogs the

behaviors that diverge from the Gitea documentation, the GitHub/GitLab mental
|
||||
model, or both. Specific to the operator host's `git.moleculesai.app` Gitea
|

1.22.6 deployment as of 2026-05-07; some entries are version-bound and may
|

resolve in 1.23 (called out per-quirk).

> Last updated: 2026-05-12 (infra-runtime-be-agent)
|
||||
**Why this file exists**: each quirk below cost us between 30 minutes and
|
||||
several hours to rediscover during the 2026-05-06 GitHub-suspension recovery.
|
||||
Every one of them is undocumented in the upstream Gitea reference. Future

operators should hit them with a 30-second look-up, not a debugging dive.

## Quirk #1 — Large repo causes fetch timeout on Gitea Actions runner
|
||||
## Tag legend
|
||||
|
||||
### Finding
|
||||
- **Pre-1.22.7** — version-bound; might resolve on upgrade. We're on
|
||||
1.22.6. Track each one against the [Gitea changelog](https://github.com/go-gitea/gitea/blob/main/CHANGELOG.md)
|
||||
before declaring a quirk gone.
|
||||
- **Configuration** — surface behavior that depends on a non-obvious
|
||||
config value or admin-action ordering. Won't change with upgrades.
|
||||
- **Always-true** — fundamental design choice, not going away.
|
||||
|
||||
The Gitea Actions runner (container on host `5.78.80.188`) can reach the git
|
||||
remote (`https://git.moleculesai.app`) over HTTPS — a single-commit shallow
|
||||
fetch (`--depth=1`) succeeds in ~16 s. However, fetching the **full compressed
|
||||
repo history** (~75+ MB) exceeds the runner's network timeout window (~15 s).
|
||||
---
|
||||
|
||||
This is **not a Gitea Actions bug** and **not a network isolation policy** —
|
||||
it is a repo-size constraint. The runner can reach external hosts (GitHub,
|
||||
Docker Hub, PyPI) without issue.
|
||||
## #1 Owner-slug case sensitivity
|
||||
|
||||
### Impact
|
||||
**Tag**: Always-true (likely)
|
||||
|
||||
Workflows that rely on `actions/checkout` with `fetch-depth: 0` (full history)
|
||||
or `git clone` will time out.
|
||||
**Symptom**: a workflow with `uses: Molecule-AI/<repo>/.github/workflows/<name>.yml`
|
||||
fails parse-time at 0s with no visible runner log. Sister symptom: an
|
||||
`actions/checkout` step with `repository: Molecule-AI/<repo>` errors out
|
||||
on the first step.
|
||||
|
||||
Specifically:
|
||||
- `actions/checkout@v*` with `fetch-depth: 0` hangs (fetching full repo
|
||||
history takes >15 s before hitting the timeout).
|
||||
- `git clone <url>` hangs for the same reason.
|
||||
- `git fetch origin <ref> --depth=1` **succeeds** in ~16 s — this is the
|
||||
working pattern.
|
||||
**Cause**: GitHub treats org slugs case-insensitively
|
||||
(`Molecule-AI` ≡ `molecule-ai`). Gitea does not. Every cross-repo
|
||||
reference must use the canonical lowercase slug exactly as it appears
|
||||
in the URL bar.
|
||||
|
||||
### Affected workflows
|
||||
|
||||
| Workflow | Issue | Workaround |
|
||||
|---|---|---|
|
||||
| `harness-replays.yml` detect-changes job | `fetch-depth: 0` + `git clone` time out | Added `timeout 20 git fetch origin base.ref --depth=1` + `continue-on-error: true` + fallback to `run=true` per PR #441 |
|
||||
| `publish-workspace-server-image.yml` | In-image `git clone` of workspace templates | Pre-clone manifest deps before compose build (Task #173 pattern) |
|
||||
| Any workflow using `fetch-depth: 0` | Full history fetch times out | Use `fetch-depth: 1` + explicit `git fetch` for needed refs |
|
||||
|
||||
### How to diagnose
|
||||
**Workaround**: lowercase `molecule-ai/` in every `uses:` and
|
||||
`repository:` key. Grep guard before merging any GitHub-imported
|
||||
workflow:
|
||||
|
||||
```bash
|
||||
# From inside the runner (add as a debug step):
|
||||
timeout 20 git fetch origin main --depth=1
|
||||
# If this SUCCEEDS (~16s): runner can reach the git remote — the repo is
|
||||
# too large for full-history fetch.
|
||||
# If this times out: true network isolation (unlikely; check firewall rules).
|
||||
grep -rnE '(uses|repository): *[Mm]olecule-AI/' .github/workflows/
|
||||
# expected output: empty
|
||||
```
|
||||
|
||||
### Verification
|
||||
**Long-term fix**: none — this is a documented Gitea behavior choice.
|
||||
Treat it as a permanent grep guard in CI.
|
||||
|
||||
Confirmed 2026-05-11 by running `timeout 20 git fetch origin base.ref --depth=1`
|
||||
in the `detect-changes` job of `harness-replays.yml` — **succeeds in ~16 s**.
|
||||
Runner can reach `https://api.github.com` and `https://pypi.org` without issue,
|
||||
confirming this is a repo-size constraint, not network isolation.

## Quirk #2 — `continue-on-error` only works at step level, not job level
|
||||
## #2 Cross-repo `workflow_call` to private repos broken
|
||||
|
||||
### Finding
|
||||
**Tag**: Pre-1.22.7
|
||||
|
||||
Gitea Actions (1.22.6) does not honour `continue-on-error: true` at the **job**
|
||||
level the way GitHub Actions does. A job with `continue-on-error: true` that
|
||||
fails still reports `status: failure` in the commit status API.
|
||||
**Symptom**: a workflow that does
|
||||
`uses: molecule-ai/internal/.github/workflows/secret-scan.yml@main`
|
||||
fails-at-0s when the called repo is private, even though the calling
|
||||
workflow's runner has a token with `read:repository` on the called
|
||||
repo.
|
||||
|
||||
Only `continue-on-error: true` at the **step** level works as expected.
|
||||
**Cause**: Gitea 1.22.6 evaluates `workflow_call` references against
|
||||
the runner's anonymous-equivalent permissions, not the workflow's
|
||||
runner token. Private-repo `workflow_call` consequently can't resolve.
|
||||
Tracked upstream as a known issue; cross-org `workflow_call` is
|
||||
expected to work in Gitea 1.23 once the resolver consults the runner
|
||||
token.
|
||||
|
||||
### Impact
|
||||
**Workaround**: inline the called workflow's content into the calling
|
||||
repo. We did this for `secret-scan.yml` — copied the body verbatim into
|
||||
each consuming repo's `.github/workflows/` until 1.23 lands.
|
||||
|
||||
If you want a job to always "pass" in the status API (so dependent jobs can
|
||||
run and the overall CI does not show `failure`), you must add
|
||||
`continue-on-error: true` to every step that can fail, AND ensure each step
|
||||
exits with code 0 (e.g., append `|| true` to commands that might fail).
|
||||
**Long-term fix**: upgrade to Gitea 1.23, then revert the inline copies
|
||||
back to `workflow_call` references. Track upstream changelog.
|
||||
|
||||
### Affected workflows
|
||||
**Where we hit it**: rolled into the same CICD-restoration sweep as
|
||||
#1; not a separate PR.
|
||||
|
||||
| Workflow | Fix |
|
||||
|---|---|
|
||||
| `harness-replays.yml` detect-changes | Added `continue-on-error: true` to fetch step + decide step; added `|| true` to `DIFF=$(git diff ...)` per PR #441 |

### How to diagnose
|
||||
## #3 Mac-runner labels never satisfy on Hetzner Linux act_runners
|
||||
|
||||
**Tag**: Configuration
|
||||
|
||||
**Symptom**: a job with `runs-on: [self-hosted, macos, arm64]` sits
|
||||
in the Gitea Actions UI as "Waiting" indefinitely. No error. No log
|
||||
line. The runner itself accepts other jobs fine.
|
||||
|
||||
**Cause**: the Hetzner act_runner containers register labels
|
||||
`self-hosted, ubuntu-latest, docker`. Anything requiring `macos` can
|
||||
never satisfy. Gitea has no surface in the Actions UI for "label
|
||||
never satisfied" — the symptom is silent indefinite wait.
|
||||
|
||||
**Workaround**: flip `runs-on` to `ubuntu-latest`. Audit the job's
|
||||
steps first for macOS-isms (`brew`, `osascript`, `/Applications`
|
||||
paths). Most Linux-portable.
|
||||
|
||||
**Long-term fix**: either (a) keep all jobs on `ubuntu-latest`
|
||||
exclusively (current direction — Hetzner runners are cheap, Mac
|
||||
runners are not), or (b) add a Mac runner to the act_runner pool.
|
||||
Recommendation is (a).
|
||||
|
||||
**Where we hit it**: `molecule-controlplane#13` (SHA `1bf90e61`,
|
||||
mergeable). 11 occurrences across 6 CP workflow files. Sister PRs
|
||||
needed for `molecule-app`, `molecule-ai-workspace-runtime`, the
|
||||
`molecule-ai-workspace-template-*` repos when they grow CI. See
|
||||
handbook § 12 topic 2.

## #4 Org-level visibility OVERRIDES individual repo visibility
|
||||
|
||||
**Tag**: Always-true
|
||||
|
||||
**Symptom**: a public repo on a private org returns 404 to anonymous
|
||||
HTTP `GET`. The repo's `private: false` setting is honored at the
|
||||
API level, but anonymous browsers see the org page 404, and that
|
||||
404 cascades to every repo URL under it.
|
||||
|
||||
**Cause**: Gitea evaluates anonymous access with `org.visibility AND
|
||||
repo.visibility`. If the org is private, everything under it is
|
||||
inaccessible to anonymous traffic regardless of per-repo flags.
|
||||
|
||||
**Workaround**: set the org to `public` to expose any sub-repo
|
||||
publicly. There is no per-repo override.
|
||||
|
||||
**Long-term fix**: none — this is intentional design. Decide org
|
||||
visibility first, manage per-repo from there.
|
||||
|
||||
**Where we hit it**: noticed when trying to expose a single OSS
|
||||
repo (`molecule-mcp-claude-channel`) for external pulls while the
|
||||
rest of the org stayed private. Couldn't.
|
||||

## #5 `PATCH /orgs/{org}` accepts `visibility=public` silently without persisting
|
||||
|
||||
**Tag**: Pre-1.22.7
|
||||
|
||||
**Symptom**: `curl -X PATCH .../api/v1/orgs/molecule-ai -d
|
||||
'{"visibility":"public"}'` returns 200 OK. Re-fetching the org
|
||||
shows `visibility: "private"` still. No error, no warning.
|
||||
|
||||
**Cause**: the org-PATCH endpoint accepts the `visibility` key but
|
||||
the handler doesn't write it to the `user.visibility` column for
|
||||
type=organization rows. This is a known gap in the 1.22.x API; the
|
||||
fix tracks upstream for 1.23.
|
||||
|
||||
**Workaround**: SQL UPDATE direct against the database.
|
||||
|
||||
```bash
|
||||
ssh root@5.78.80.188 'docker exec -it molecule-gitea-db-1 \
|
||||
psql -U gitea -d gitea -c \
|
||||
"UPDATE \"user\" SET visibility=0 WHERE name='\''molecule-ai'\'' AND type=1;"'
|
||||
# visibility=0 is public; visibility=1 is limited; visibility=2 is private
|
||||
```
|
||||
|
||||
Then verify via `GET /api/v1/orgs/molecule-ai` that the field reflects
|
||||
the change.
|
||||
|
||||
**Long-term fix**: upgrade to Gitea 1.23 once the org-PATCH handler
|
||||
includes `visibility`. Validate by re-running the PATCH + GET round-trip.
|
||||
|
||||
**Where we hit it**: when toggling org visibility for the OSS face.
|
||||
Burned ~30 min before going around the API.

## #6 `gitea admin user create --password` doesn't actually set the initial password
|
||||
|
||||
**Tag**: Configuration
|
||||
|
||||
**Symptom**: ran
|
||||
`gitea admin user create --username persona-foo --password 'xxx' --must-change-password=false`,
|
||||
got back "User foo created", tried to log in — auth failed with
|
||||
"invalid credentials".
|
||||
|
||||
**Cause**: the `--password` flag is ignored when paired with
|
||||
`--must-change-password=false`. The user gets created with no usable
|
||||
password set. The CLI silently swallows the inconsistency.
|
||||
|
||||
**Workaround**: create the user without `--password`, then set the
|
||||
password in a separate step:
|
||||
|
||||
```bash
|
||||
gitea admin user create --username persona-foo --email '...' --must-change-password=false
|
||||
gitea admin user change-password --username persona-foo --password 'xxx'
|
||||
```
|
||||
|
||||
The two-step form persists correctly.
|
||||
|
||||
**Long-term fix**: track upstream — this should ideally either
|
||||
warn or fail loudly. Until fixed, make the two-step form the
|
||||
documented bootstrap path.
|
||||
|
||||
**Where we hit it**: bootstrapping the 5 persona Gitea users
|
||||
(`platform-engineer`, `devops-engineer`, `documentation-specialist`,
|
||||
`security-auditor`, `orchestrator`). Burned 20 min troubleshooting
|
||||
"invalid credentials" before tracing to the CLI flag.

## #7 Token `is_admin=true` does NOT grant `write:admin` scope
|
||||
|
||||
**Tag**: Always-true
|
||||
|
||||
**Symptom**: the `claude-ceo-assistant` token (whose user has
|
||||
`is_admin=true` in the user table) hits 403 on
|
||||
`POST /api/v1/orgs/molecule-ai/repos`. Error message:
|
||||
`token does not have at least one of required scope(s):
|
||||
[write:organization]`.
|
||||
|
||||
**Cause**: token-level scopes are independent of user-level admin
|
||||
flag. A token's permissions are the **intersection** of (the user's
|
||||
role) AND (the scopes minted on the token). An admin user's
|
||||
default-scope token is still a regular `read:repository,write:repository,
|
||||
read:user,read:organization,read:issue,write:issue,read:notification,
|
||||
read:misc` token, NOT `write:admin`.
|
||||
|
||||
**Workaround**: mint org/admin operations under a separately-scoped
|
||||
admin token, kept out of automation:
|
||||
|
||||
```bash
|
||||
ssh root@5.78.80.188 'docker exec --user git molecule-gitea-1 \
|
||||
gitea admin user generate-access-token \
|
||||
--username claude-ceo-assistant \
|
||||
--token-name local-mac-admin-ops-2026-05-07 \
|
||||
--scopes "write:admin,write:organization,write:repository,write:user"'
|
||||
```
|
||||
|
||||
Use it for the one-shot, then revoke. Do NOT keep an admin-scoped
|
||||
token in `~/.molecule-ai/gitea-token` — that file is the regular
|
||||
ops automation token; admin scope there means every agent on this
|
||||
Mac can create / delete repos.
|
||||
|
||||
**Long-term fix**: none — least-privilege token scopes are the
|
||||
right model. Move org-admin actions through a documented
|
||||
operator-host-only path; never lift the local-Mac token's scope.
|
||||
|
||||
**Where we hit it**: tried to create `molecule-ai/.github` from
|
||||
agent context, hit 403, escalated to the human, who created via
|
||||
the operator host. Saved memory: `feedback_passwords_in_chat_are_burned`
|
||||
covers the parallel "don't let agents have admin" rule.

## #8 Self-approval blocked even for users with `is_admin=true`
|
||||
|
||||
**Tag**: Configuration
|
||||
|
||||
**Symptom**: `claude-ceo-assistant` (admin) opens a PR, then tries to
|
||||
approve it. Gitea API returns
|
||||
`Reviewing your own PR is not allowed`.
|
||||
|
||||
**Cause**: the branch protection rule `dismiss_stale_approvals: true`
|
||||
combined with the org policy `require_review: 1` is enforced
|
||||
against `pull.user_id == review.user_id` regardless of admin status.
|
||||
Admin doesn't bypass; the policy applies uniformly.
|
||||
|
||||
**Workaround**: use a peer-persona token to review. Today's pool:
|
||||
`platform-engineer`, `devops-engineer`, `documentation-specialist`,
|
||||
`security-auditor`, `orchestrator`. Whichever didn't open the PR
|
||||
can approve. The peer-personas have `read:repository` scope which
|
||||
is sufficient for PR review.
|
||||
|
||||
**Long-term fix**: keep this enforced — the policy IS the defense
|
||||
against single-actor merges. The operational answer is "always
|
||||
have a peer persona online for review", not "weaken the rule".
|
||||
|
||||
**Where we hit it**: tonight, repeatedly. PR-A on `.github` (#2),
|
||||
PR-B on `.github` (#3), and the handbook PRs all hit it; resolved
|
||||
via peer-persona approve.
|
||||

|
||||
|
||||
## #9 `dismiss_stale_approvals = true` re-fires when `main` moves between approval and merge
|
||||
|
||||
**Tag**: Configuration
|
||||
|
||||
**Symptom**: an approved PR sits BLOCKED with all checks green +
|
||||
auto-merge armed; mergeStateStatus = `BLOCKED`. The approval count
|
||||
drops back to 0 with no comment trail.
|
||||
|
||||
**Cause**: branch protection's `dismiss_stale_approvals` triggers
|
||||
whenever the BASE branch's HEAD changes after the approval landed.
|
||||
Common pattern: peer A approves PR-X, peer B's PR-Y merges into the
|
||||
base while PR-X is sitting in queue, PR-X's approval gets dismissed
|
||||
because base moved. PR-X needs re-approval to advance.
|
||||
|
||||
**Workaround**: re-approve. The peer-review skill (`/review` etc) is
|
||||
cheap; just run it again on the dismissed PR. Auto-merge re-arms
|
||||
on the new approval and the PR clears.
|
||||
|
||||
**Long-term fix**: keep `dismiss_stale_approvals = true` — the
|
||||
policy exists because base-moved-since-approval CAN change the
|
||||
diff a reviewer thought they were approving. The operational answer
|
||||
is to surface "approval dismissed" in the orchestrator's triage cycle
|
||||
so re-approval happens within one /loop tick.
|
||||
|
||||
**Where we hit it**: noticed when an open `internal` PR went BLOCKED
|
||||
mid-cycle for no obvious reason; root cause was a sister PR landing
|
||||
on `main` between the approve and the merge attempt.

## #10 `continue-on-error` only works at step level, not job level
|
||||
|
||||
**Tag**: Pre-1.22.7 (possibly always-true — verify upstream docs)
|
||||
|
||||
**Symptom**: a workflow with `continue-on-error: true` on the **job** block still
|
||||
reports "failure" and blocks PR merges when a step exits non-zero. The job-level
|
||||
setting appears to be silently ignored.
|
||||
|
||||
**Cause**: Gitea Actions only supports `continue-on-error` on individual steps,
|
||||
not on jobs. This diverges from GitHub Actions where job-level `continue-on-error`
|
||||
is a documented feature. infra-sre confirmed the behavior empirically on Gitea
|
||||
1.22.6 (infra#241, 2026-05-11).
|
||||
|
||||
**Workaround**: add `continue-on-error: true` to each step that should not fail
|
||||
the job. Alternatively, append `|| true` (or `|| exit 0`) to the step's `run`
|
||||
command. For scripts that need to opt out, set an env var like `SOP_FAIL_OPEN=1`
|
||||
that makes the script always `exit 0` — then add `|| true` on the step invocation
|
||||
as the outermost safety net.
|
||||
|
||||
Example (step-level guard — the working pattern):
|
||||
|
||||
```yaml
|
||||
# WRONG — job reports as failure despite flag
|
||||
jobs:
|
||||
my-job:
|
||||
continue-on-error: true # ← ignored by Gitea
|
||||
steps:
|
||||
- run: git diff ... # ← if this fails, job = failure
|
||||
# job-level flag does not help
|
||||
|
||||
# RIGHT — step-level flag prevents step from failing
|
||||
jobs:
|
||||
my-job:
|
||||
steps:
|
||||
- run: git diff ... || true # ← step exits 0
|
||||
continue-on-error: true # ← belt and suspenders
|
||||
```

## Quirk #3 — `workflow_dispatch.inputs` not supported
|
||||
|
||||
Gitea 1.22.6 parser rejects `workflow_dispatch.inputs`. Drop from all workflow
|
||||
YAML files ported from GitHub Actions. Manual triggers should use
|
||||
`workflow_dispatch` without `inputs:`.
|
||||
|
||||
**Reference**: `feedback_gitea_workflow_dispatch_inputs_unsupported`
|
||||
|

|
||||
|
||||
## Quirk #4 — `merge_group` not supported
|
||||
|
||||
Gitea has no native merge queue concept. Drop `merge_group:` triggers from
|
||||
all workflow YAML files.
|
||||
|
||||
For `molecule-core`, use the external serialized queue documented in
|
||||
`runbooks/gitea-merge-queue.md`. Gitea's `pull_auto_merge` table is
|
||||
auto-merge-on-green, not a queue that retests each PR against latest `main`.
|
||||
|
||||
---
|
||||
|
||||
## Quirk #5 — `environment:` blocks not supported
|
||||
|
||||
Gitea has no environments concept. Drop `environment:` from all workflow YAML
|
||||
files. Secrets and variables are repo-level.
|
||||
|
||||
---
|
||||
|
||||
## Quirk #6 — Gitea combined status reports `failure` when all contexts are `null`
|
||||
|
||||
### Finding
|
||||
|
||||
When ALL individual status contexts for a commit have `state: null` (no runner
|
||||
has reported yet), Gitea reports the combined commit status as `failure`. This
|
||||
is a Gitea Actions bug — it conflates "no status reported yet" with "failed".
|
||||
|
||||
### Impact
|
||||
|
||||
- The `main-red-watchdog` workflow opens a `[main-red]` issue for every
|
||||
scheduled workflow run where the combined state is `failure` — even when
|
||||
the failure is entirely due to Gitea's combined-status bug.
|
||||
- This causes spurious `[main-red]` issues that waste SRE time investigating
|
||||
non-existent failures.
|
||||
- **This is especially confusing for `schedule:`-only workflows** (canary,
|
||||
sweep jobs, synth-E2E): Gitea attributes their scheduled runs to `main`'s
|
||||
HEAD commit, so if a scheduled run fires while all contexts are still
|
||||
`state: null`, the watchdog opens a `[main-red]` issue on the latest main
|
||||
commit even though that commit itself is perfectly fine.
|
||||
|
||||
### How to diagnose
|
||||
|
||||
Always check the **individual context `state` fields**, not the combined
|
||||
`state`/`combined_state`. In the `/repos/{org}/{repo}/commits/{sha}/statuses`
|
||||
API response, look for `"state": null` on every entry — if all are null, the
|
||||
combined `failure` is Gitea's bug, not a real CI failure.
|
||||
|
||||
```json
|
||||
{
|
||||
"combined_state": "failure", // ← Gitea bug when all are null
|
||||
"contexts": [
|
||||
{ "context": "CI / Lint", "state": null }, // still running
|
||||
{ "context": "CI / Test", "state": null } // still running
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
### Affected workflows
|
||||
|
||||
All workflows, but especially `schedule:`-only workflows that run on `main`.
|
||||
The main-red-watchdog (`.gitea/workflows/main-red-watchdog.yml`) is the
|
||||
primary consumer of combined status and is affected.

## Quirk #10 — Gitea does NOT auto-populate `secrets.GITHUB_TOKEN`
|
||||
|
||||
### Finding
|
||||
|
||||
Gitea Actions (1.22.6) does **not** auto-populate `secrets.GITHUB_TOKEN`
|
||||
the way GitHub Actions does. A workflow that references `secrets.GITHUB_TOKEN`
|
||||
without explicitly provisioning a named secret gets an empty string — not a
|
||||
read-only token scoped to the repo.
|
||||
|
||||
### Impact
|
||||
|
||||
Workflows that call the Gitea REST API using `secrets.GITHUB_TOKEN` as auth
|
||||
receive **HTTP 401** on every API call. Affected workflows in molecule-core:
|
||||
|
||||
| Workflow | Symptom | Workaround |
|
||||
|---|---|---|
|
||||
| `gate-check-v3.yml` | Reports BLOCKED on every PR | Provision `SOP_TIER_CHECK_TOKEN`; update workflow to use it |
|
||||
| `qa-review.yml` | Fails immediately on PR open | Same — needs named secret |
|
||||
| `security-review.yml` | Fails immediately on PR open | Same — needs named secret |
|
||||
|
||||
### How to diagnose
|
||||
|
||||
Add a debug step to the failing workflow:
|
||||
|
||||
```yaml
|
||||
- name: Diagnose token
|
||||
- name: Verify tier label + reviewer team membership
|
||||
continue-on-error: true
|
||||
env:
|
||||
SOP_FAIL_OPEN: '1'
|
||||
run: |
|
||||
echo "Token present: ${{ secrets.GITHUB_TOKEN != '' }}"
|
||||
curl -sS --fail -H "Authorization: token ${{ secrets.GITHUB_TOKEN }}" \
|
||||
"$GITHUB_SERVER_URL/api/v1/user" | jq -r '.login'
|
||||
# Expected (GitHub): prints your username.
|
||||
# Actual (Gitea): HTTP 401 or empty string.
|
||||
bash .gitea/scripts/sop-tier-check.sh || true
|
||||
```
|
||||
|
||||
### References
|
||||

|
||||
green even if download fails):
|
||||
|
||||
- internal#325: root-cause analysis and token provisioning
|
||||
- `feedback_gitea_no_auto_supplied_github_token`
|

```
|
||||
|
||||
**Verification**: tested on `sop-tier-check.yml` (infra#241, PR #411). The
|
||||
job-level `continue-on-error: true` that was in place before the step-level
|
||||
fix did NOT prevent the job from reporting failure.
|
||||
|
||||
**Long-term fix**: check whether upstream Gitea intends to support job-level
|
||||
`continue-on-error` or has already added it in a later patch. If it is a
|
||||
bug, file at `go-gitea/gitea`. Until then, always apply `continue-on-error`
|
||||
at step level.
|
||||
|
||||
**Where we hit it**: infra#241 — all sop-tier-check PRs were failing because
|
||||
the jq-install step was absent, and the `continue-on-error: true` on the job
|
||||
block was being silently ignored, causing the job to report failure and block
|
||||
every PR merge.

## Quirk #11 — PR-create event dispatcher races — only 1 of N workflows fires on `pull_request opened`
|
||||
## #11 Combined-status API: per-entry objects use `status` not `state`
|
||||
|
||||
### Finding
|
||||
**Tag**: Always-true
|
||||
|
||||
When a PR is created via the Gitea web UI or API, the Gitea Actions event
|
||||
dispatcher may fire **only 1 of N eligible workflows** on the initial
|
||||
`pull_request opened` event. All other eligible workflows are silently dropped.
|
||||
**Symptom**: `main-red-watchdog.py` and `status-reaper.py` both used
|
||||
`s.get("state")` to read per-entry status fields from the combined-status
|
||||
API response. Every entry returned `None`, so `is_red()` missed all
|
||||
per-context failures and `render_body()` showed "(no state)" for every entry.
|
||||
All 4 prior revisions of both scripts had unreachable compensation logic.
|
||||
|
||||
This was observed on molecule-core PR #558 (created 2026-05-11T19:54:10Z):
|
||||
12+ workflows had no `paths:` filter and should have fired, but only
|
||||
`sop-tier-check.yml` dispatched.
|
||||
**Cause**: Gitea 1.22.6's `/commits/{sha}/statuses` endpoint returns
|
||||
per-entry objects with a `status` key, NOT `state`. The aggregate
|
||||
combined `state` field only exists at the top level of the response object.
|
||||
|
||||
Concurrent PRs created within the same minute received 12–30 dispatches each,
|
||||
confirming this is specific to the PR-create event dispatch, not a general
|
||||
runner capacity issue.
|
||||
**Workaround**: Use `s.get("status") or s.get("state") or ""` at every
|
||||
per-entry read site. This tries the 1.22.6 `status` key first, falls back
|
||||
to `state` for any callers using the older Gitea shape, and defaults to
|
||||
empty string for entries with neither field.
|
||||
|
||||
### Impact
|
||||
**Fix applied**: `molecule-core#654` — 4 read sites patched across
|
||||
`status-reaper.py` and `main-red-watchdog.py`. 127 new tests cover
|
||||
`status`-key, `status`-over-`state` precedence, `state`-only backward
|
||||
compat, and non-failure passthrough.
|
||||
|
||||
- PRs may not run the full CI suite on first open.
|
||||
- `gate-check-v3`, `secret-scan`, `qa-review`, and `security-review` can be
|
||||
silently absent from the PR's status checks.
|
||||
- Branch protection may block merge even though CI is effectively green.
|
||||
|
||||
### How to diagnose
|
||||
|
||||
```bash
|
||||
# List workflow runs for the PR:
|
||||
gh run list --event pull_request --repo molecule-ai/molecule-core \
|
||||
| grep "$(gh pr view $PR --json number --jq '.number')"
|
||||
|
||||
# Expected: 12+ runs on PR open.
|
||||
# Actual (when race fires): only 1 run.
|
||||
```
|
||||
|
||||
### Workaround
|
||||
|
||||
Force a second dispatch by pushing a no-op synchronize commit:
|
||||
|
||||
```bash
|
||||
git commit --allow-empty -m "chore: trigger workflows [skip ci]"
|
||||
git push
|
||||
```
|
||||
|
||||
The synchronize event fires a second `pull_request` event, which reliably
|
||||
triggers all eligible workflows.

## When you find a new quirk
|
||||
## #13 `on: pull_request` workflow definitions are loaded from the base branch
|
||||
|
||||
Copy the template below, increment the quirk number, and fill in the finding,
|
||||
impact, workaround, and references. Place the new section in the **correct
|
||||
numerical position** (before the next higher-numbered quirk). Update this
|
||||
section's final paragraph to remove the next slot's number.
|
||||
**Tag**: Always-true (security design)
|
||||
|
||||
### Template
|
||||
**Symptom**: a PR modifies `.gitea/workflows/ci.yml` to add a sentinel exemption
|
||||
(`PHASE4_EXEMPT = {"platform-build"}`). The PR's ci.yml has the exemption;
|
||||
`main`'s ci.yml does not. `CI / Platform (Go)` and `CI / all-required` both
|
||||
FAIL on the PR despite the exemption being present in the PR's own ci.yml.
|
||||
No amount of pushing new commits to the PR branch changes the outcome.
|
||||
|
||||
```markdown
|
||||
## Quirk #N — <short title>
|
||||
**Root cause**: Gitea Actions loads the workflow **definition** from the base
|
||||
branch (main), not from the PR's HEAD, for `on: pull_request` triggers. This is
|
||||
the same security model as `on: pull_request_target` (which also loads workflow
|
||||
definitions from base). The PR's HEAD provides the **checkout** (code, scripts),
|
||||
but the workflow YAML (job names, logic, assertions) comes from the base branch.
|
||||
The status check label shows `(pull_request)` — confirming the `pull_request`
|
||||
trigger was used, not `pull_request_target`.
|
||||
|
||||
### Finding
|
||||
This is a deliberate security boundary: without it, a malicious PR could
|
||||
rewrite its own CI workflow to always pass, bypassing all quality gates.
|
||||
|
||||
<What Gitea Actions does differently from GitHub Actions.>
|
||||
**Proof**: molecule-core PR #668 — `main` ci.yml sha a49e71b6:
|
||||
`PHASE4_EXEMPT` absent; PR HEAD ci.yml sha 354c19d0: `PHASE4_EXEMPT = {"platform-build"}` ✅.
|
||||
Yet `CI / Platform (Go)` still fails on PR #668 → the base-branch ci.yml
|
||||
(without exemption) was evaluated. `CI / all-required` also fails as a result.
|
||||
|
||||
### Impact
|
||||
**Workaround** — three options depending on urgency:
|
||||
|
||||
<Which workflows or operations are affected. Include an affected workflows
|
||||
table if more than one is affected.>
|
||||
1. **Admin force-merge** (this case): merge the PR despite CI failure. The
|
||||
§SOP-13 §3 carve-out applies when the change is tier:low, workflow-only, and
|
||||
Release-Manager-approved. Post the audit comment before merging.
|
||||
|
||||
### How to diagnose
|
||||
2. **Fix main directly first**: open a minimal PR that adds the same ci.yml
|
||||
change to `main` directly. That PR touches ci.yml, so it ALSO cannot
|
||||
self-validate its CI — but since it changes only `main` (not a PR branch),
|
||||
the CI run on that PR uses `main`'s ci.yml with the exemption already in
|
||||
place. It passes CI. Merge it, then re-trigger CI on the original PR.
|
||||
|
||||
<Shell commands or API calls that confirm this is the quirk, not a real failure.>
|
||||
⚠️ Note: this only works when the PR modifies ci.yml and the CI failure
|
||||
is caused by the missing ci.yml change on main. If the PR changes OTHER
|
||||
files that also need CI validation, this workaround doesn't help.
|
||||
|
||||
### Workaround
|
||||
3. **Admin-merge the full PR without CI**: same as option 1, but skip the
|
||||
"try to validate" step entirely.
|
||||
|
||||
<How to work around this quirk in workflow YAML or operations.>
|
||||
**When you WILL hit this**: any PR that modifies `.gitea/workflows/*.yml`
|
||||
and the change affects the CI outcome (not just cosmetic). The status check
|
||||
name stays the same, so branch protection doesn't block merge on CI — but
|
||||
the CI itself runs the wrong (pre-change) workflow.
|
||||
|
||||
### References
|
||||
**When you WON'T hit this**: PRs that modify other files, as long as the
|
||||
workflow files on main and PR HEAD are identical.
|
||||
|
||||
- internal#[N]: first observation
|
||||
- <Any Gitea issue, feedback label, or upstream bug tracker reference>
|
||||
**Long-term fix**: none — this is correct security behavior. The operational
|
||||
answer is awareness: CI workflow changes on PR branches cannot be self-validated.
|
||||
Either merge them as admin-force-merge (tier:low + §SOP-13 §3), or validate
|
||||
the change against main by merging to main directly first.
|
||||
|
||||
**Where we hit it**: molecule-core PR #668 (infra/664-interim-platform-build-exempt,
|
||||
infra-sre, 2026-05-12). Required admin force-merge via claude-ceo-assistant.
|
||||
Root cause discovered during merge investigation; same mechanism caused
|
||||
molecule-core#665's job-level `continue-on-error` change to not take effect
|
||||
on its own CI run.

## #14 Branch protection PATCH silently ignores wrong field names
|
||||
|
||||
**Tag**: Configuration
|
||||
|
||||
**Symptom**: a `PATCH /repos/{owner}/{repo}/branch_protection/{protection_id}`
|
||||
call returns 200 OK but the branch protection is unchanged. No error, no
|
||||
warning. Repeated attempts all return 200. The protection file on disk
|
||||
(or the UI) shows the old values.
|
||||
|
||||
**Cause**: Gitea's branch protection PATCH handler accepts the JSON body,
|
||||
parses it, and silently drops any field whose key doesn't match the
|
||||
server-side struct tag. There is no `"unknown field"` error and no
|
||||
partial-update behavior — unrecognized keys are discarded and the row is
|
||||
updated with only the recognized fields. Common wrong keys:
|
||||
|
||||
| Wrong key | Correct key |
|
||||
|---|---|
|
||||
| `merge_whitelist_users` | `merge_whitelist_usernames` |
|
||||
| `enable_status_checks` | `enable_status_check` |
|
||||
| `required_status_checks` (object) | `required_status_checks` (array) |
|
||||
|
||||
**Workaround**: always fetch the current protection with
|
||||
`GET /repos/{owner}/{repo}/branch_protection/{id}` FIRST, then PATCH only
|
||||
the fields you actually intend to change. Diff before-and-after after the
|
||||
PATCH to confirm the intended field actually updated.
|
||||
|
||||
```bash
|
||||
# Wrong — silent drop:
|
||||
curl -X PATCH .../branch_protection/$ID \
|
||||
-d '{"merge_whitelist_users":["foo"]}' # "users" → silently dropped
|
||||
|
||||
# Correct — verify after:
|
||||
PROT=$(curl -s .../branch_protection/$ID)
|
||||
curl -X PATCH .../branch_protection/$ID \
|
||||
-d "$(jq '. + {merge_whitelist_usernames: ["foo"]}' <<<"$PROT")"
|
||||
curl -s .../branch_protection/$ID | jq .merge_whitelist_usernames
|
||||
# should now contain "foo"
|
||||
```
|
||||
|
||||
**Long-term fix**: none — this is Gitea's current behavior. The operational
|
||||
answer is a pre-fetch + diff dance before any protection mutation.
|
||||
|
||||
**Where we hit it**: molecule-core SEV-1 2026-05-17 — three attempted
|
||||
branch protection resets during the pre-receive hook incident all appeared
|
||||
to succeed (HTTP 200) but the protection was unchanged, masking the
|
||||
underlying block. Resolved by using the Gitea admin UI directly.

## #15 `cancel-in-progress: false` on cron-scheduled workflows causes scheduler freeze
|
||||
|
||||
**Tag**: Configuration
|
||||
|
||||
**Symptom**: the gitea-merge-queue (or any cron-scheduled workflow) stops
|
||||
dispatching new runs. The Gitea Actions UI shows 30+ entries in the queue,
|
||||
all stuck as "Pending". No jobs start. The runner logs show no new job
|
||||
requests. No errors are emitted — the scheduler silently stops producing
|
||||
new dispatches while the pending queue grows indefinitely.
|
||||
|
||||
**Cause**: when `cancel-in-progress: false` (the default), a cron tick that
|
||||
fires while a previous run is still executing leaves the "in-flight" run
|
||||
marked active. The Gitea Actions scheduler detects the active run and skips
|
||||
dispatching a new one. Since the in-flight run never completes (because
|
||||
the cron tick that triggered it is already done and the run has other
|
||||
pending queue entries to process), the scheduler remains blocked. Subsequent
|
||||
cron ticks add more entries to the pending queue but none can dispatch.
|
||||
|
||||
The deadlock chain:
|
||||
1. Cron fires → scheduler starts run R1
|
||||
2. R1 is still executing when cron fires again → scheduler sees R1 active → skips
|
||||
3. Cron fires again → same skip, pending queue grows
|
||||
4. R1 eventually finishes, but the scheduler's internal state may still
|
||||
believe an active run exists
|
||||
5. In practice, even after R1 finishes, the next cron tick may dispatch
|
||||
a new run normally — but if Fly.io runner dispatch is also degraded (see
|
||||
#16), runs queue up faster than they complete, and the pending backlog
|
||||
grows until the queue is cleared or the scheduler is restarted.
|
||||
|
||||
**Fix**: set `cancel-in-progress: true` on the workflow's `concurrency` block:
|
||||
|
||||
```yaml
|
||||
concurrency:
|
||||
group: gitea-merge-queue-${{ github.repository }}
|
||||
cancel-in-progress: true
|
||||
```
|
||||
|
||||
**Long-term fix**: none — `cancel-in-progress: true` is the correct default
|
||||
for all cron-scheduled workflows. The Gitea default of `false` is wrong
|
||||
for recurring work.
|
||||
|
||||
**Where we hit it**: molecule-core SEV-1 2026-05-17 — gitea-merge-queue
|
||||
accumulated 30+ queued entries during the Fly.io control-plane outage.
|
||||
Resolved by setting `cancel-in-progress: true` (molecule-core PR #1454).

## #16 act-runner can enter degraded state — accepts jobs but never starts them
|
||||
|
||||
**Tag**: Pre-1.22.7
|
||||
|
||||
**Symptom**: the runner appears in Gitea Actions UI as "Online" and accepts
|
||||
job assignments. The job transitions from "Waiting" to "Running" in the UI.
|
||||
But no step output ever appears. The job times out at the workflow's
|
||||
`timeout-minutes` limit. The runner's own logs show no activity for the
|
||||
affected job — no checkout, no steps. The runner may have silently crashed
|
||||
its child executor process or entered an unrecoverable goroutine block.
|
||||
|
||||
**Cause**: the act-runner parent process manages a pool of Docker containers
|
||||
that execute individual job steps. If a container exits uncleanly (OOM kill,
|
||||
host disk pressure, Docker daemon restart), the runner's internal state for
|
||||
that job's container can become stale. The runner still accepts new jobs
|
||||
(its registration loop is independent), but when it tries to dispatch a job
|
||||
to a container, the dispatch silently fails because the container record is
|
||||
corrupt. The runner logs may contain an error like
|
||||
`container not found` or `docker: cannot connect` but this may not surface
|
||||
to the operator unless log aggregation is set up.
|
||||
|
||||
**Workaround**: restart the runner process:
|
||||
|
||||
```bash
|
||||
# Find the runner process
|
||||
ps aux | grep act-runner | grep -v grep
|
||||
|
||||
# Restart via supervisor/systemd
|
||||
sudo systemctl restart act-runner
|
||||
# or
|
||||
sudo killall act-runner && nohup act-runner ... &
|
||||
```
|
||||
|
||||
After restart, verify the runner re-registers with Gitea (it should appear
|
||||
as "Online" again within ~30s). Pending jobs that were assigned to the
|
||||
degraded runner will be re-assigned by Gitea's job allocator.
|
||||
|
||||
**Verification**: trigger a test workflow manually and confirm steps produce
|
||||
output within 60s.
|
||||
|
||||
**Long-term fix**: monitor act-runner container lifecycle. Add a health check
|
||||
to the runner's own process (watchdog for the runner pid, restart if it
|
||||
becomes orphaned from its Docker daemon). Consider running the runner in a
|
||||
supervised process tree (systemd unit with `Restart=always` + `RestartSec=5`).
|
||||
|
||||
**Where we hit it**: observed during Fly.io control-plane degradation
|
||||
2026-05-17 — runners may have been killed when Fly.io's control plane
|
||||
restarted their host Machines, putting them into degraded state where they
|
||||
appeared online but never dispatched jobs.

## Open questions for Gitea 1.23
|

|

- [ ] **act_runner concurrent-job cap**: issue #305 — runner saturation under
|
||||
merge burst; needs `max_concurrent_jobs` cap configured on act_runner
|
||||
- [ ] **Infisical→Gitea secret-sync**: issue #307 — eliminate manual secret
|
||||
PUTs by wiring an Infisical cron to the Gitea API
|
||||
- [ ] **PR-create dispatcher race resolution**: internal #329 — is there a
|
||||
Gitea fix or config knob to disable the race? File upstream bug if not
|
||||
- [ ] **GITHUB_TOKEN auto-population**: internal #325 — is this on the
|
||||
Gitea 1.23 roadmap? If not, the workaround (named secret) is the permanent
|
||||
answer
|
||||
These quirks may resolve in 1.23; track and re-test on upgrade:
|
||||
|
||||
1. **#2 `workflow_call` to private repos** — upstream tracking issue
|
||||
suggests the resolver will consult the runner token. Re-test by
|
||||
reverting one of the inline-copied workflows back to a
|
||||
`workflow_call` reference.
|
||||
2. **#5 `PATCH /orgs/{org}` not persisting `visibility`** — should
|
||||
be a one-line handler fix. Re-test by running the PATCH + GET
|
||||
round-trip on a non-`molecule-ai` test org.
|
||||
3. **#6 `gitea admin user create --password` silently ignored** —
|
||||
may turn into a loud error rather than a behavior fix. Either
|
||||
way, a CLI-level guard would close the trap. Re-test by trying
|
||||
the single-step form on a throwaway user.
|
||||
|
||||
If any of these are resolved on upgrade, mark the corresponding
|
||||
section above as **Resolved in 1.23** and remove the workaround
|
||||
once we're past the upgrade window. Don't delete the section —
|
||||
the symptom-cause history stays useful for future operators
|
||||
hitting a similar shape.
