It uses OpenRouter's free +models and the repository secret `OPEN_ROUTER_API_KEY`. The feature becomes +active when these workflows and scripts are merged into `apache/pinot`'s default +branch; adding the files in an unmerged PR does not deploy it. + +## Triggers and controls + +- PRs targeting `master` signal on open, new commits, reopen, becoming ready for + review, and description edits. `PR flow signal` has no credentials, checkout, + or PR-controlled shell input. After a successful signal, `PR flow` runs trusted + default-branch scripts and obtains the PR's public source evidence through the + GitHub API. It never checks out or executes the PR's code. +- An hourly run at minute 17 scans at most 200 candidates in a rotating window + and selects a bounded backlog, by default at most three PRs. Rotation gives + later PRs a turn when earlier ones repeatedly fail. This also recovers work + when an external contributor's signal is waiting for approval or an earlier + generation failed. Scheduling and free capacity do not guarantee immediate + updates. +- Check the regenerate checkbox inside an existing bot block to request another + generation. A signature made with an HMAC key derived from the OpenRouter + secret identifies the bot-owned block. The raw secret is never embedded in the + PR. Author text edits refresh the explanation; bot-only updates and unrelated + commits to `master` do not spend quota when the PR diff is unchanged. +- Set repository variable `PR_FLOW_ENABLED=false` to stop generation. Any other + value, including an unset variable, enables it. `PR_FLOW_MODEL` selects the + model; its default is `nvidia/nemotron-3-super-120b-a12b:free`. + +Only model IDs ending in `:free` are accepted, with routing restricted to zero +input/output prices. There is no paid fallback. Free model availability, +per-minute limits and the account's daily request quota can stop a run. Retries +also consume capacity. An hourly scan is bounded recovery, not a way around +OpenRouter's account limits; monitor its account dashboard and the Actions run +summary. If the selected free model disappears, choose another supported `:free` +model in `PR_FLOW_MODEL` and preview it before relying on its output. + +## Preview and regenerate + +Maintainers can generate a preview without editing the PR: + +```sh +gh workflow run pr-flow.yml -R apache/pinot --ref master \ + -f pr_number=12345 -f preview=true +``` + +Add `-f force=true` to regenerate an already current revision. Omit +`-f preview=true` to publish the result. Leave `pr_number` empty to process the +bounded backlog; `-f max_prs=3` controls the selection bound, accepting 1–10. +Manual dispatch +executes scripts from the selected workflow ref, so use `master` or an explicitly +reviewed, trusted maintainer ref. Never dispatch a privileged run against +untrusted PR code. + +The Actions run summary reports the outcome. Artifacts retain the generated +`flow.md`, sanitized `usage.json` and `status.json`, and the public PR's previous +description in `previous-description.json` for recovery, for seven days. +Publication also retains `publication-edit-history.json`. GitHub offers no atomic +conditional update of a PR description: a human edit in the final read/write +interval can still be overwritten. The publisher audits edit history afterward, +retains intervening edits for recovery, and reports a conflict instead of success. +It stops before writing when history cannot be read. Resolve a reported conflict +from the retained snapshots before regenerating the flow. +Failed generation, invalid output, or exhausted free +capacity preserves the previous diagram. The publisher rechecks the PR head +before writing so an obsolete generation cannot overwrite a newer revision's +flow. Per-PR concurrency serializes writers; it does not cancel an active job. + +Rotating `OPEN_ROUTER_API_KEY` changes the derived signing key. Existing block +signatures become unverified, and `force` does not bypass signature checks or +overwrite manually edited blocks. A maintainer must remove the old managed block +from the PR description once, preserving the author's text, then force a new +generation. + +## Evidence and maintenance + +The diagram is a model-generated overview, not a human review, approval, test +result, or guarantee of complete runtime behavior. Source collection and prompt +size are bounded. The output identifies omitted or truncated evidence; large +PRs can therefore receive a partial overview. The model may still miss behavior +or connections even when the diagram renders successfully. + +The workflows use Python 3.12 and SHA-pinned GitHub actions. The repository's +existing Dependabot `github-actions` entry maintains action updates. Privileged +runs check out only the workflow scripts at the trusted workflow SHA with +persisted Git credentials disabled. The signal/check workflows receive no +OpenRouter secret. The main workflow separates read-only planning from +PR-description writing and avoids `pull_request_target`, following the +[ASF GitHub Actions policy](https://infra.apache.org/github-actions-policy.html). + +Run the focused checks locally: + +```sh +python3 -m unittest discover -s .github/scripts/pr_flow -p 'test_*.py' +actionlint .github/workflows/pr-flow-signal.yml \ + .github/workflows/pr-flow.yml .github/workflows/pr-flow-checks.yml +``` diff --git a/.github/scripts/pr_flow/main.py b/.github/scripts/pr_flow/main.py new file mode 100644 index 00000000000..e3280dbb67c --- /dev/null +++ b/.github/scripts/pr_flow/main.py @@ -0,0 +1,497 @@ +# Licensed to the Apache Software Foundation (ASF) under one +# or more contributor license agreements.
