Problem

A GitLab merge request shows its whole head pipeline as one "Pipeline" check. When it fails, the checks panel can't say which job broke, so you have to open GitLab to find out. GitHub pull requests list each check in the same panel. Fixes #13431.

Change

The checks and detail reads now also ask GitLab's GraphQL API for the head pipeline's stages and their jobs, in one request alongside the existing trigger job read.

• Each job becomes a check named after its stage, like test / unit, with GitLab's status and label, linking to the job log.
• Jobs allowed to fail show as neutral. Retried attempts are left out, so a job counts by its latest run. Manual jobs stay neutral.
• A stage whose job list GitLab didn't return whole stays one check with GitLab's stage status. That covers more than 100 jobs, jobs GitLab couldn't resolve, and jobs without a name.
• If the stages can't be read whole, or the pipeline has none, the single "Pipeline" check stays as before.
• Trigger job rows from fix(gitlab): a failed child pipeline no longer shows as a passing check #24688 are still appended after the jobs.

The read sits behind the existing downstreamChecks flag, so the permission check before writes still skips it. No paging, no cache, no new setting. Everything is in packages/source-control-gitlab.

Scope and approval

#13431 is a triaged bug (accepted). An earlier attempt, #13434, listed every job over REST and was closed as too large. GraphQL removes the paging, caching and trigger status logic that made it big.

This PR first showed stages, with a failed stage replaced by its failed jobs. Testing on a self-managed GitLab found that a cancelled job beside a failed one disappeared, and a running stage didn't say which job was running. Per #26869 it now lists every job, which matches GitHub's check runs and costs the same single request.

Verification

• Decoder tests in gitLabMergeRequestJson.test.ts: every job listed under its stage with success, failed, allowed-failure, cancelled, running and manual statuses, and a retried attempt left out. A table of incomplete job lists (none, empty, more than one page, an unresolved job, a job without a name) each keeps the stage as one check. Partial or missing stages return nothing.
• CLI tests in GitLabPullRequestCli.test.ts: the request sends the right project path and iid, a failed GraphQL read keeps the "Pipeline" check, and downstreamChecks: false makes a single call.
• Checked that every queried job field (retried, detailedStatus, allowFailure, webPath) exists in gitlab.com's GraphQL schema.
• vp run check:changed passes.
• The screenshots below were taken on the earlier stages version, against a real gitlab.com merge request with a failed openapi job in its test stage.

Approvability

Verdict: Approved at 7df82c5

Macroscope's review found this PR approvable — GitLab checks now identify pipeline stages and the jobs responsible for failures. The additional lookup is read-only and falls back to the existing pipeline check when stage details are unavailable.

Walkthrough

GitLab merge-request details now include checks decoded from head-pipeline stages and eligible failed jobs. Stage checks are read alongside trigger-job checks. Tests cover successful reads, read failures, and disabled downstream checks.

Full details: Out of Scope Changes check

Explanation

The changes are limited to packages/source-control-gitlab. The GraphQL stage query, stage decoder, fallback behavior, downstreamChecks gating, trigger-job integration, and focused tests all support the GitLab checks behavior in [#13431]. No unrelated product area, setting, cache, or paging feature is added.

Full details: Title check

Explanation

The title "fix(gitlab): the checks panel lists each pipeline job" matches the main change. The PR makes GitLab merge-request checks list head-pipeline stages and their jobs instead of one "Pipeline" check. The title is specific and follows a conventional-commit format. It says "each pipeline job", while the change lists jobs under their stages and keeps some stages as single checks, so the wording is slightly narrower than the full behavior. This does not make the title unrelated.

Full details: Description check

Explanation

The description includes complete Problem, Change, Scope and approval, and Verification sections. It explains the behavior, implementation, issue scope, focused tests, observed results, limitations, screenshots, and agent details. It does not include an explicit maintainer approval comment, but it provides the triaged issue and scope rationale, so the description is mostly complete.

Full details: Linked Issues check

Explanation

Issue [#13431] requires one named, linked check per CI job, including running and successful jobs. decodePipelineStageChecksJson emits one check per stage and expands only failed stages into failed jobs. Jobs in non-failed stages remain grouped under the stage check. The existing trigger-job behavior is retained, but the primary per-job requirement remains unmet.

Resolution

Change the head-pipeline decoding and read path to emit an individual check for every relevant CI job, including running and successful jobs, with the job name and log URL. Preserve the trigger-job status and link behavior. Add or update tests for running, successful, failed, and incomplete job reads, including the required fallback.

verified unchanged head 7df82c58127c860b0fb4864a3602446e73318ed5 on linux, using repository playwright and /usr/bin/google-chrome.

• reproduced on github/main (e6e2ab05cc) in a separate worktree before checking this head. installed dependencies and ran one real dev server at a time with isolated app state.
• added projects for real cloned repositories through the web app, created threads, and completed real codex gpt-6.1-sol turns on main and this head. no mocked service responses or seeded scenario data.
• used the same completed mesa merge request, mesa/mesa!45769 on gitlab.freedesktop.org, pipeline 1780727. main showed one failed Pipeline check. this head shows six failed arm / panfrost-… jobs and five passing stage checks, with the summary 6 of 11 failing.
• exercised both the thread checks popover and merge request detail checks. “show all” preserves the passing stages. clicked the first failed job row and reached job 114510732, named panfrost-g610-vk:arm64 1/4; after the host's verification prompt its real log loaded and ended with ERROR: Job failed: exit code 1.
• vp run check:changed HEAD^ passed through blacksmith on the exact public head: formatting, lint, knip, typechecks for 11 affected packages, and 108 tests. the two directly affected test files also passed separately (93 tests).

after, this head against the same pipeline:

Not verified

native desktop, ios, and android clients; remote/relay connections; authenticated gitlab writes and merge request activity; a live downstream-trigger pipeline, allowed-failure job, graphql-unavailable fallback, or pipeline exceeding 100 stages. existing focused tests cover fallback and downstream decoding, but those are not live-service verification.

main also reproduced the single-check behavior on gitlab.com/gitlab-org/cli!3956. gitlab.com then rate-limited unauthenticated graphql traffic, so its after state could not be checked. gnome's detail endpoint returned http 406. the completed before/after verification above uses freedesktop's real gitlab service instead.

takeover verification, 2026-11-03

merged current main into the contributor branch without conflicts or a rebase; head 13a737a855284f2310d4330523cbeabc4e90aaa6. no implementation changes were needed. the diff against main remains the same four gitlab files.

blacksmith passed vp run check:changed github/main: format, lint, knip, typechecks for 11 packages, and 119 tests. the two directly affected files passed separately with 104 tests. the previously failing MessagesTimeline browser file passed all 38 tests on both main and the candidate; an earlier candidate run failed its scroll-position assertion, so that test was not consistently green locally. two independent read-only reviews found no confirmed defects. the remaining incomplete-job review thread is covered by the current fallback and was resolved.

this run did not repeat live gitlab or client verification. the earlier evidence above is historical and predates the contributor's change to display every job.

Detect incomplete job connections before expanding a failed stage.

297-302: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Detect incomplete job connections before expanding a failed stage.

CiStage.jobs is a paginated CiJobConnection. With more than 100 jobs, jobs(first: 100) can omit later jobs. The query does not request that connection's pageInfo, so the decoder can emit only the failed jobs from the first page and replace the stage check with an incomplete list. Request and inspect jobs.pageInfo.hasNextPage, then return the existing fallback when the job list is incomplete.

Suggested fix

-            jobs(first: 100) { nodes { name status allowFailure webPath } }
+            jobs(first: 100) {
+              nodes { name status allowFailure webPath }
+              pageInfo { hasNextPage }
+            }
...
     jobs: Schema.optional(
-    Schema.NullOr(Schema.Struct({ nodes: Schema.Array(Schema.NullOr(RawStageJobSchema)) })),
+    Schema.NullOr(
+      Schema.Struct({
+        nodes: Schema.Array(Schema.NullOr(RawStageJobSchema)),

Checked against a self-managed GitLab

This covers some of the "not verified" items above: allowed failures, a live trigger job with a failed child pipeline, manual jobs, and a retried job.

Setup: GitLab 19.5.3 (CE, self-managed), head e39247a11a. I called the provider's getChangeRequestChecks with the real glab doing every request. The UI was not part of this run. The merge request's head pipeline has these jobs:

Stage	Job	GitLab status
build	build (retried once)	success
build	compile-docs	success
test	lint	success
test	unit-tests	failed
test	flaky-optional (allow_failure: true)	failed
test	slow-job	canceled
deploy	package (needs unit-tests)	skipped
deploy	deploy-manual (when: manual)	manual
deploy	release-gate (manual through rules, blocking)	manual
deploy	child-pipeline (trigger, no strategy: depend)	success, child pipeline failed

GitLab reports the pipeline as manual ("Blocked waiting for manual action") even though unit-tests failed.

On main the checks are:

Pipeline        neutral   push
child-pipeline  failure   Downstream pipeline

So main shows the failed job as neutral, and only the child pipeline row makes the merge request look red. Without a trigger job it would read as passing.

On this PR:

build              success   passed
test / unit-tests  failure   .../-/jobs/207789
deploy             neutral   manual action
child-pipeline     failure   Downstream pipeline

That matches GitLab. The allowed failure stays out, the retried build counts by its latest attempt, and the child pipeline row is still there.

One gap: slow-job was cancelled in the same failed stage, and it doesn't appear anywhere. The stage is replaced by its failed jobs only, so a cancelled job next to a failed one disappears. Listing cancelled jobs (other than allowed failures) alongside the failed ones when expanding a failed stage would fix it.
