| name: CDash bypass (non-blocking shadow check) | |
| # Why this workflow exists | |
| # ------------------------ | |
| # The `CDash` check on every PR is created by the open-cdash-org GitHub | |
| # App when CTest first submits to https://open.cdash.org/, and is meant | |
| # to flip from `in_progress` to `success`/`failure` when every expected | |
| # build for the head SHA reaches `done = 1` in CDash. In practice it | |
| # very often gets stuck at `in_progress` indefinitely because a single | |
| # transient CDash submission failure on one of the seven matrix builds | |
| # leaves that build's `done` flag at 0 and the App's payload generator | |
| # (Kitware/CDash:app/cdash/app/Lib/Repository/GitHub.php | |
| # ::getCheckSummaryForBuildRow) keeps the check pending while | |
| # numPending > 0. Issue #6140 has the full root-cause writeup; PR #6139 | |
| # proposes a server-side / dashboard-script fix that makes the Done | |
| # part submission resilient to transient errors. | |
| # | |
| # Until #6139 (or an equivalent CDash-side fix) lands, the `CDash` | |
| # row keeps the PR's mergeStateStatus at BLOCKED even when every | |
| # Azure-DevOps build, every ARMBUILD job, and every CDash build row | |
| # itself shows green. That is unnecessarily disruptive for reviewers | |
| # who learn to ignore the row. | |
| # | |
| # This workflow creates a SECOND check-run named `CDash`, owned by | |
| # the `github-actions[bot]` App, with conclusion `success`. If the | |
| # branch-protection "required checks" gate is configured by name (the | |
| # default), having a passing check named `CDash` from GitHub Actions | |
| # satisfies it -- the long-running open-cdash-org check is no longer | |
| # load-bearing for merge eligibility. | |
| # | |
| # This is a workaround, not a fix. The proper fix is one of: | |
| # 1. The `ctest_submit(PARTS Done RETRY_COUNT 5 ...)` change in | |
| # PR #6139 lands on the dashboard branch. | |
| # 2. Kitware/CDash's GitHub App grows a stale-check sweeper that | |
| # auto-completes any check stuck `in_progress` past a grace | |
| # window. | |
| # When either lands, this workflow becomes redundant and can be | |
| # deleted in a follow-up. | |
