fix(release): self-heal a lost CDN rebuild and surface tap push errors - #77
Merged
Conversation
The CDN manifest every installed client polls was kept correct by a single fire-and-forget webhook POST. On 0.18.0 that POST hit four consecutive 60s connect timeouts, the job only warned, and the consistency gate then polled a manifest nobody had asked to rebuild -- the release stayed invisible until a human fired the webhook by hand. The consistency poll now re-fires the deploy trigger every 8 attempts while the CDN is behind, so a lost trigger heals inside the job that gates on it. The Homebrew tap bump has failed twice with its real cause swallowed by stdio: 'ignore'. Git's stderr now reaches the log, with the token redacted.

📝 WalkthroughWalkthroughThe release flow retriggers lost CDN rebuild requests during polling, validates an optional Dokploy webhook, extends timeout budgets, and reports retrigger counts. Homebrew updates use a scoped GitHub App token. Git failures include sanitized diagnostics without exposing credentials. ChangesCDN release consistency
Git release updates
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟠 High · up to This PR adds automatic CDN retriggers and richer Homebrew push diagnostics, but the current release workflow still uses a mutable action while handling a private key, may expose the tap token through unsanitized error details, and can defer malformed webhook failures until the consistency gate. These security and release-reliability issues should be fixed before merge. Sequence Diagram(s)sequenceDiagram

- Line 36: Update both Git failure handlers in the release script to sanitize
the Error cause before retaining it: replace the raw child-process error with an
object containing only redacted, approved diagnostic fields. Apply the same
change to the handlers around both Homebrew tap operations, including the throw
that reports “Failed to clone Homebrew tap,” while preserving the existing
user-facing message.
In `@scripts/release/verify-release-consistency.mjs`:
- Around line 63-66: Update the webhook validation in the release consistency
configuration to parse the string with URL and enable retrigger only when the
parsed URL protocol is exactly https:. Treat invalid URLs and non-HTTPS
protocols as disabled, preserving the existing warning behavior and preventing
polling from receiving an unusable callback.
- Line 119: Update the timeout message in the CDN polling output near
cdnPoll.attempts and cdnPoll.retriggers to remove the extra closing parenthesis,
so it renders “rebuild request(s)” with only the intended punctuation.

TAP_GITHUB_TOKEN was created before the org was renamed from Pythoughts-labs to PyModel, so the tap clone succeeds (public repo, token unused for the read) and only the push is refused. That broke the tap bump on 0.17.1 and 0.18.0. The job now mints an installation token from pythinker-release-bot, scoped with owner + repositories to homebrew-tap alone so it carries no write access to pythinker-code. App tokens are minted per run and do not expire, which retires this failure class rather than resetting its clock.

.changeset/use-app-token-for-brew-tap.md.github/workflows/release.yml
The tap failure handlers kept the raw execFileSync error as Error.cause. Its message and stderr both carry the credentialed clone URL, so the cause chain held an un-redacted token that any future inspection of the error object would print into a public Actions log. Everything useful is already extracted and redacted into the thrown message, so the cause carried no information. The webhook guard tested a string prefix, which admits values fetch rejects. It now parses the URL and requires an https protocol and a non-empty host, so an unusable webhook disables rebuild requests at configuration time instead of producing a callback that throws on first use.

Without a permission-* input, actions/create-github-app-token mints a token carrying every permission the App installation holds -- here that includes pull-request write, which cloning and pushing the Homebrew tap never uses. Supplying one input switches the action to strict opt-in, so the token now carries contents write and nothing else.

Problem
The CDN manifest at
https://code.pythinker.com/pythinker-code/latest.jsonis what every installedclient polls for updates, and its correctness rested on exactly one fire-and-forget webhook POST
in the
redeploy-cdnjob.On the 0.18.0 release that POST hit four consecutive
curl: (28)60-second connect timeouts. Thejob emitted only a
::warning::(correctly — npm has already published irreversibly by then), andverify-cdn-releasethen polled a manifest that nobody had asked to rebuild. It sat at 0.17.1 forthe full 600s budget and failed, and the release stayed invisible to every installed client until a
human fired the webhook by hand.
The pipeline had no path from "the trigger was lost" back to "ask again". 0.17.1 succeeded by
timing, not by design.
Separately,
scripts/release/update-brew-formula.mjsrangit pushunderstdio: 'ignore'andreplaced whatever git said with the constant string
Failed to push Homebrew tap. The tap bump hasnow failed on 0.17.1 and 0.18.0 and GitHub's actual refusal has never been seen, so the auth root
cause is still a guess.
What changed
CDN — the consistency poll now heals a lost trigger.
pollCdnUntilCaughtUptakes an optionalretriggercallback andretriggerEveryAttempts;verify-release-consistency.mjssupplies onethat re-POSTs the Dokploy deploy webhook every 8 attempts (~2 min at the 15s interval, matching the
Dokploy build time) while the CDN is behind. The poll is the only pipeline stage that both knows the
CDN is still stale and is still running, so it is the right place for the retry.
retriggeris swallowed exactly like a failed fetch — a trigger that cannot be sent islag, not a gate failure.

redeploy-cdnkeeps its warn-don't-fail posture.verify-cdn-releasestays the loud gate.Homebrew tap — git's real error now reaches the log. Both the clone and the push capture stdout
and stderr and rethrow with the actual message. A redaction helper collapses the credentialed
userinfo (
//x-access-token:…@) to//***@and replaces the raw token, so the credential cannotland in a public Actions log. No auth mechanism or credential is changed here — this is the
diagnostic that tells us which fix the tap actually needs.
