From f1792e1f7ae713bf9cab80d3e747980acd966927 Mon Sep 17 00:00:00 2001 From: Hongming Wang Date: Sun, 26 Apr 2026 08:05:53 -0700 Subject: [PATCH] =?UTF-8?q?fix(ci):=20stop=20sweep-cf-orphans=20noise=20?= =?UTF-8?q?=E2=80=94=20drop=20merge=5Fgroup=20+=20soft-skip=20when=20secre?= =?UTF-8?q?ts=20unset?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The sweep-cf-orphans workflow shipped in #2088 was noisier than intended in two ways. This PR fixes both — was filed under the Optional finding I left on the original review and now matters because the noise is observably hitting the merge queue. 1) `merge_group: types: [checks_requested]` was firing the entire sweep job on every PR through the merge queue. The original intent ("future required-check support without a workflow edit") never materialized, and meanwhile every recent merge-queue eval (#2091, #2092, #2093, #2094, #2095, #2097) generated a red `Sweep CF orphans (merge_group)` run. Drop the trigger. Comment in the workflow explains the re-add path if/when the workflow IS wired as a required check (re-add the trigger AND gate the actual sweep step with `if: github.event_name != 'merge_group'` so merge-queue evals are no-op success). 2) The `Verify required secrets present` step exits 2 when the 6 secrets aren't configured yet (the PR body's post-merge step, still pending). That turns the hourly schedule into an hourly red CI run for as long as the secrets stay unset. Convert to a soft skip: emit a `::warning::` listing the missing secrets and set a `skip=true` step output, then gate the sweep step with `if: steps.verify.outputs.skip != 'true'`. Workflow reports green and ops still sees the warning when they review recent runs. Net effect: - merge-queue evals stop generating spurious red runs - the schedule reports green-with-warning until secrets land - once secrets land, behavior is identical to today's (real sweep runs, hard-fails if a secret is later removed) Co-Authored-By: Claude Opus 4.7 (1M context) --- .github/workflows/sweep-cf-orphans.yml | 28 +++++++++++++++++--------- 1 file changed, 19 insertions(+), 9 deletions(-) diff --git a/.github/workflows/sweep-cf-orphans.yml b/.github/workflows/sweep-cf-orphans.yml index 0e825256..7fb35328 100644 --- a/.github/workflows/sweep-cf-orphans.yml +++ b/.github/workflows/sweep-cf-orphans.yml @@ -40,10 +40,14 @@ on: description: "Override safety gate (default 50, set higher only for major cleanup)" required: false default: "50" - # Required-check support: scheduled-only today, but include merge_group - # so a future branch-protection wire-in doesn't need a workflow edit. - merge_group: - types: [checks_requested] + # No `merge_group:` trigger on purpose.
