ci: converge fork and internal PRs on a single required merge gate - #42194
Conversation
Fork PRs to release cannot merge: branch protection requires qc-result and 'perform-test / ci-test-result', which the external-contributor flow never emits for forks, so GitHub blocks the merge on a missing required context. Introduce a single required status context, ci/merge-gate, written on the PR head SHA by whichever flow knows it: merge-gate.yml (workflow_run) for internal PRs, and a set-fork-merge-gate job in build-client-server.yml on the trusted /approve-ci dispatch for fork PRs. The raw per-flow checks now feed the gate instead of being individually required. Branch protection must be updated separately (release only) to require mergefreeze + ci/merge-gate.

WalkthroughThe pull-request adds shared merge-gate evaluation for internal and fork pull requests. It adds workflow triggers, pending-state handling, Cypress status publication, strict pull-request validation, and final commit-status updates. ChangesMerge gate workflows
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to Internal pull requests can remain permanently blocked once ci/merge-gate becomes required, so the check-run name mismatch should be fixed before merge. Sequence Diagram(s)sequenceDiagram

Address review of the ci/merge-gate convergence: - Extract shared logic to .github/workflows/scripts/merge-gate.js; both entry points use it (no drift). - merge-gate.yml now also listens to 'External PR credential-free validation' and triggers on in_progress + completed, forcing a re-running workflow's own input to pending so an earlier success can't linger during a same-SHA rerun. - Fork side persists the approved Cypress result as the ci/fork-cypress commit status and an early mark-fork-gate-pending job brackets the rerun window; the gate is recomputed on both fork inputs, closing the stale-success / stuck-pending holes. - Both entry points validate open + base==release + head.sha==written-SHA before writing (no stale writes, no reuse after base retarget). - Robust PR resolution: workflow_run.pull_requests -> head owner:branch -> commit association, unique exact-SHA match only, no arbitrary fallback; null head.repo treated as fork. - ci/fork-cypress requires exactly one Cypress result job to have run. Fail-closed throughout: skipped/neutral/missing/in-flight => pending. Linear: https://linear.app/appsmith/issue/APP-15921

site:docs.github.com GitHub Actions reusable workflow check run name caller job called workflow job name
💡 Result:
In GitHub Actions, when a reusable workflow is triggered, the check run name displayed in the GitHub UI is primarily determined by the job definition in the caller workflow [1][2]. Specifically: 1. Caller Job Name: You use the jobs.<job_id> key to define the job in your caller workflow, and you can provide a custom name using the jobs.<job_id>.name property [3][4]. This name property is what GitHub typically displays in the UI for that job, including within the check runs list [3][5]. 2. Called Workflow Execution: When you use the uses keyword to call a reusable workflow, the entire execution of that called workflow is encapsulated within the job defined in the caller workflow [1][2]. The job_id and name assigned to that job in the caller workflow effectively serve as the label for that reusable workflow execution in the UI [3][4]. 3. Context: The called workflow does not independently override the check run name of the caller's job [2]. While you can set a run-name for the entire workflow in both the caller and called files to help distinguish workflow runs in the "Actions" tab, the individual job's display name is controlled by the jobs.<job_id>.name field in the caller's configuration [3][6]. To control how the reusable workflow appears in your checks list, you should set a descriptive name on the job in your caller workflow [4][5].

🌐 Web query:
site:docs.github.com " / " "reusable workflow" "check" job name
💡 Result:
To determine if a job in a GitHub Actions workflow is calling a reusable workflow, you can check for the presence of the uses key within that specific job configuration [1][2]. In a YAML workflow file, a job that calls a reusable workflow is defined by using the uses keyword at the job level [1][3]. If a job includes uses, it is a call to a reusable workflow, rather than a standard job that uses the runs-on and steps keywords [1][2]. Key characteristics to identify these jobs include: - The presence of jobs.<job_id>.uses [4][5]. - A structure that typically excludes standard job-level steps, as reusable workflows are called directly within the job [1][2]. - You can identify the specific reusable workflow being called by the value provided to the uses key, which references the workflow file path [1][2][3]. If you are monitoring workflow execution via the GitHub REST API or audit logs, you can identify jobs that call reusable workflows by examining the job_workflow_ref field in the data recorded for prepared_workflow_job events, which specifies the path of the called reusable workflow [3]. Within the workflow run itself, context variables like job.workflow_ref may also provide information about the workflow file defining the job [6].

GitHub Actions REST checks.listForRef reusable workflow check run name caller job slash called job
💡 Result:
When using the GitHub Actions REST API checks.listForRef endpoint, there is no direct, single-property link between a check_run and the specific caller or called job names within a reusable workflow context [1][2]. Key technical realities: 1. Checks vs. Jobs: The checks.listForRef API retrieves check runs by commit SHA across all workflows [3][4]. Check runs are distinct from "workflow jobs" [5]. While every workflow job typically generates a check run [6], the REST API for check runs does not inherently embed the "caller job" or "called job" hierarchy directly in the check run object [1]. 2. Identifying Reusable Workflow Usage: The checks API provides generic metadata [1]. If you need to identify relationships between caller and called jobs, you should use the actions/runs/{run_id}/jobs REST API instead [5]. This endpoint returns detailed job information, including the workflow_name and, for reusable workflows, the hierarchy can be inferred using the referenced_workflows field available in the workflow run object [2][5][7]. 3. Workaround/Contextual Linking: - For internal identification, use the github context within your workflows. Specifically, job.workflow_ref and job.workflow_sha provide context about the file defining the currently running job [8]. Note that these resolve differently depending on whether you are in the caller or the reusable workflow [7]. - If you need to link a check run back to a specific job ID, you can cross-reference the check_run_url or check_run_id (if available in the context) returned by the Jobs API with the data from the Checks API [8][5]. Summary: You cannot retrieve the "caller job" name directly from the checks.listForRef response [1]. You must instead query the Actions Jobs API using the specific run_id to obtain the workflow hierarchy and job metadata [5][7].

Match the actual check-run name
readRef passes raw check runs to checkOutcome, which requires an exact c.name match. The Checks API returns perform-test, not perform-test / ci-test-result, so the internal gate remains pending after Cypress completes. Use perform-test consistently in WORKFLOW_TO_CHECK and the internal check list.

Problem
External-contributor (fork) PRs to
releasecan pass every check, be reviewed, and be DP-validated, yet staymergeStateStatus: BLOCKED. Example: #41927.releasebranch protection requires status contexts by exact name —mergefreeze,qc-result,perform-test / ci-test-result. The external-contributor flow (#42061) gates the internal jobs off for forks (head.repo.full_name == github.repository) and instead emitsexternal-ci-result(credential-free) plusci-test-*-resultfrom the/approve-cidispatch. So on a fork PRqc-resultis skipped andperform-test / ci-test-resultis never created → GitHub keeps a required context in "Expected" forever → merge blocked. (The rollup looks green because it only aggregates checks that ran.)Fix
One required status context,
ci/merge-gate, written on the PR head SHA, computed by shared logic in.github/workflows/scripts/merge-gate.js.

Requiresqc-result+perform-test / ci-test-resultgreen.build-client-server.ymlon the trusted/approve-cidispatch. Requiresexternal-ci-result+ the approved Cypress result green. The Cypress result is persisted as theci/fork-cypresscommit status so it survives and can be re-read.merge-gate.ymlalso feeds the fork side: it listens toExternal PR credential-free validationtoo, so a credential-free rerun recomputes the gate.Fail-closed by construction: anything not proven green — skipped, neutral, missing, or in-flight — maps to

No stalesuccesswhen credential-free re-runs and fails; no stuckpendingif credential-free finishes after Cypress.pending.merge-gate.ymltriggers onin_progressand forces the re-running workflow's own input topending, so an earliersuccesscan't linger during a same-SHA rerun. Fork side: an earlymark-fork-gate-pendingjob setspendingwhen/approve-cistarts.base == release, andhead.sha == the SHA being written— blocks stale writes and reuse of results after a base retarget.workflow_run.pull_requests→ headowner:branch(forks are absent frompull_requests) → commit association, requiring a unique exact-SHA match. Anullhead.repo(deleted fork) is treated as a fork.ci/fork-cypressissuccessonly if exactly one of the three result jobs ran and passed; 0 or >1 fails closed.Companion step — branch protection (admin, after merge + live validation)
