Adding GitLab support

What and why

I have noted that I am not alone wanting to do such thing (several issues and opened PRs, I think I have seen some more than 6 months old), and I guess it is not a high priority for the team, so I decided to make a small PR that does it, easy to review, basically maximally piggy-backing on gh code. It should thus be easy to maintain and review, since it is quite minimal.

An example of an issue: #6445.

The PR changes +345/−31 source lines (+330/−16 ignoring whitespace) and adds 112 test lines. An example of some open PRs, much harder to review: #7018 (actually currently broken from when I tested it) and the huge #8241 (an issue with several sub PRs ^^'), if you prefer it, obviously go for it :)

Done

For a workspace on a GitLab remote:

  • Status: the sidebar and PR status show its MR (draft, open, merged, closed).
  • Checks: each job of the head pipeline is a check.
  • Review: "approved" or "review required".
  • Actions: Create PR, Merge (merge, squash, rebase) and Ready for review run glab mr create|merge|update.

Design (optimizing for ease of coding and reviewing, lazy but not dirty)

  • Detection: a remote is GitLab when glab knows its host (glab config get api_host --host <host>). That's a local read. A known host is remembered, so a refresh spawns nothing for it, and a host added later shows at the next refresh.
  • No host settings in Superset: every call is glab … -R https://<host>/<path>, and glab maps SSH-alias and self-managed hosts itself. (Easy to do for edge case setups and the like, glab config only, any llm would do it in a giffy if someone has any issue...) => this makes the code much simpler obviously
  • Identity: a GitLab owner is host/group (an HTTPS port is kept). MRs of two instances never collide, and Merge/Ready choose GitLab when the owner has a slash, which a GitHub login can't. => this makes the code much simpler obviously and is easy to understand for future coders :) it avoids quite a lot of useless complexity to handle
  • Reuse: MRs map onto the existing PR shape, so caching, linking and storage are reused unchanged. Nothing is written to the project row.

Follow-up: #8724 adds MR discussions, CI job logs, the PR pane (content, diff, close/reopen) and creating a workspace from an MR. (again same mindset... easy to review, feel free to do it after this one... It looks bigger because it is on top of main obviously, if you merge this one it will be much smaller obviously)

How I tested it

I had a llm do lots of scenarios in a desktop dev build on a self-managed GitLab. Unit tests cover the linking, the remote parsing and the host detection; bun test in packages/host-service passes.

Checklist

  • PR title follows conventional commits (type(scope): subject)
  • bun run lint passes. bun run typecheck reports no errors in the changed files; the local desktop check fails on unrelated UI-library types.
  • "Allow edits from maintainers" is checked on fork PRs

A workspace whose remote is on a GitLab host now shows its merge request
the way a GitHub workspace shows its pull request: state, draft, merged,
the head pipeline as its check, and "review required" when approval is
missing. Create PR opens a merge request with `glab mr create`.

Every GitLab call is a `glab` subprocess, like the `gh` path, so it uses
the user's own `glab auth login`. Superset passes `-R https://<host>/<path>`
built from the remote, and glab maps that host to its API host itself,
so self-managed instances and SSH host aliases work without any host
settings in Superset.

- A host is GitLab when its name contains "gitlab"; other hosts never
  spawn glab.
- The GitLab identity is not written to the project row: avatars, clone
  matching and the Octokit procedures read projects.repo* as GitHub.
- Merge and Ready for review stay hidden for non-GitHub PRs. They call
  GitHub by owner/repo/number, which a GitLab MR can share with a GitHub
  mirror of the same project.

📝 Walkthrough

The pull-request runtime now recognizes GitLab repositories and uses glab to discover, refresh, create, merge, and mark ready merge requests. Workspace upstream resolution and pull-request links also support GitLab.

Changes: GitLab merge-request support

Layer / File(s) Summary
Remote parsing and CLI execution
packages/shared/src/gitlab-remote.ts, packages/shared/src/gitlab-remote.test.ts, packages/shared/package.json, packages/host-service/src/runtime/pull-requests/utils/workspace-refs.ts, packages/host-service/src/trpc/router/workspace-creation/utils/exec-gh.ts
The shared package exports a GitLab remote parser for SSH and HTTPS remotes. Workspace upstream resolution accepts GitLab remotes, and the shared CLI helper exposes execGh and execGlab.
Merge-request discovery and status refresh
packages/host-service/src/runtime/pull-requests/pull-requests.ts, packages/host-service/src/runtime/pull-requests/utils/github-query/github-gitlab-query.ts, packages/host-service/src/runtime/pull-requests/utils/github-query/index.ts, packages/host-service/src/runtime/pull-requests/utils/github-query/github-gitlab-query.test.ts, packages/host-service/src/runtime/pull-requests/pull-requests.test.ts
The runtime resolves GitLab repository identities and uses GitLab queries to find merge requests and derive review and pipeline status. The tests cover GitLab workspace refresh and its recorded glab repository argument.
GitLab merge-request creation
packages/host-service/src/trpc/router/pull-requests/procedures/create-for-workspace.ts
The workspace procedure creates a GitLab merge request through glab, parses its number and URL, and refreshes workspace links.
GitLab merge-request actions and links
packages/host-service/src/trpc/router/github/github-gitlab.ts, packages/host-service/src/trpc/router/github/index.ts, packages/host-service/src/trpc/router/git/utils/reply-to-review-comment.ts, packages/host-service/src/trpc/router/pull-requests/procedures/merge.ts, apps/desktop/src/renderer/routes/_authenticated/_dashboard/v2-workspace/$workspaceId/components/ChangesControl/components/PRStatusGroup/PRStatusGroup.tsx, apps/desktop/src/renderer/routes/_authenticated/_dashboard/v2-workspace/$workspaceId/components/ChangesControl/components/PRStatusGroup/components/PRDetailCard/PRDetailCard.tsx
GitLab merge and ready actions use glab; the public router uses the GitHub/GitLab integration module. Pull-request link labels now read “Open in browser.”

1104-1110: 🚀 Performance & Scalability | 🔵 Trivial

GitLab identity is recomputed on every refresh without caching.

For each GitLab project, getProjectRepository runs git remote get-url and resolveDefaultBranch on every call. Callers include performProjectRefresh and createForWorkspace. The code does not persist GitLab identity, by design. The cost is two git spawns per refresh. This is acceptable now. Consider a short in-memory cache if refresh frequency grows.

Merge and Ready for review now work for a linked GitLab MR: the github
router runs `glab mr merge` (squash and rebase map to their flags,
auto-merge off so the result matches GitHub's immediate merge) and
`glab mr update --ready`.

The callers send owner/repo/number only, so the host picks GitLab when a
linked GitLab MR has that identity, and refuses when a linked GitHub PR
has it too: a GitLab project and its GitHub mirror share owner/repo, and
a guess could merge the wrong one. The lookup reads the runtime's own
pull_requests rows (the rows the PR chip shows), next to
findPullRequestRow, so github.ts reads no snapshot fields. This replaces
the renderer guard that hid both actions for GitLab MRs, and also covers
mobile.

Included review availability: This review used your included allowance. Your plan provides up to 10 included reviews per hour; 7 remain after this review.

A GitLab owner now carries its host (`gitlab.example.com/group`, with the
HTTPS port when the remote names one; an SSH port is not the web port):

- MRs of two GitLab instances with the same path and number no longer
  share a cache entry or a pull_requests row.
- An HTTPS remote on a non-default port keeps its port in the glab URL.
- Merge and Ready for review pick GitLab when the owner has a slash,
  which a GitHub owner never has. No stored row is consulted, so a GitHub
  PR can never be routed to glab, and the runtime lookup is gone.

Also from review:
- A merge request without a string sha is skipped instead of being
  stored with headSha "undefined"; a pipeline without a URL has none.
- A failed refresh after creating an MR is logged, as on the GitHub path.
- The PR menu and card say "Open in browser" (an existing catalog
  string) instead of "View on GitHub".

Files that now hold GitLab code are renamed to github-gitlab-*. The
`@superset/shared/github-remote` export keeps its name so its importers
do not change.
Renaming github-remote.ts to github-gitlab-remote.ts showed as a full
delete and re-add, since the GitLab part nearly doubles that small file.
The GitLab parser now lives in its own gitlab-remote.ts (exported as
`@superset/shared/gitlab-remote`), so github-remote.ts and its importers
stay untouched and the change is a plain addition.

Review follow-up for the two items that were not inline threads:

  • Outside-diff note on the "View on GitHub" label: fixed in 084f131. The PR menu and card now say "Open in browser", a string already in every catalog, so no .po change.
  • Nitpick on recomputing the GitLab identity on each refresh: left as is, as the nitpick suggests (two git calls per GitLab project refresh).

…ab errors

- Each job of the MR's head pipeline is a check (`glab ci get`), as each
  GitHub check run is. An allowed-to-fail job counts as neutral, and a
  manual job as skipped, so neither keeps the MR red or pending.
- An MR with at least one approval shows as approved (approvals API,
  reached through the MR's own web host and project id). "Review
  required" still comes from detailed_merge_status.
- execGlab rejects with glab's own reason (its stderr) instead of
  execFile's "Command failed: glab ..." line, which repeated the whole
  command, MR description included. Create, merge and ready failures now
  read like the GitHub path's.

A remote is GitLab when glab has a config entry for its host, not when
the host name contains "gitlab": self-managed instances on any host name
(git.company.com) now link their merge requests.

The check is `glab config get api_host --host <host>`: a local config
read, no network. Each answer is cached per host for five minutes, so a
refresh spawns nothing for a host seen recently, and a later `glab auth
login` is picked up. Only remotes that are not GitHub are checked.
…en GitLab does

- A manual job that may not fail blocks its pipeline, so it stays a
  pending check; only an optional manual job counts as skipped.
- "Approved" needs GitLab's own `approved: true` as well as an approver:
  an approval can exist while required rules are still unmet.

…and workspace from MR

Builds on the GitLab support in ParadevAI#8719, through the same glab calls:

- Discussions: the Review tab and the PR pane read an MR's discussions
  (diff notes as review threads, other notes as conversation), reply to
  a thread and resolve or reopen it.
- Job logs: "Copy job logs" works for a failed GitLab CI job
  (`glab ci trace`), for jobs of the MR's own project only.
- PR pane: a GitLab MR link opens in Superset's PR pane. Its ref keeps
  the host in the repo name, so the GitHub fallbacks never read it as a

…ts gaps

- The PR head and details lookups pick glab or GitHub inside one
  cachedGitHubFetch call instead of repeating it per provider.
- Comments say why a fork MR is never linked (GitLab names the source
  project by id only), why "approved" also needs an approver (GitLab
  reports `approved` when no approval rule applies), and that GitLab has
  no case-drift sweep yet (its source-branch filter is case-sensitive).

…and workspace from MR

Builds on the GitLab support in ParadevAI#8719, through the same glab calls:

- Discussions: the Review tab and the PR pane read an MR's discussions
  (diff notes as review threads, other notes as conversation), reply to
  a thread and resolve or reopen it.
- Job logs: "Copy job logs" works for a failed GitLab CI job
  (`glab ci trace`), for jobs of the MR's own project only.
- PR pane: a GitLab MR link opens in Superset's PR pane. Its ref keeps
  the host in the repo name, so the GitHub fallbacks never read it as a
  GitHub repo. Content, diff (`glab mr diff --raw`), merge, close and
  reopen, and ready or draft all run through glab. Writes reuse the
  GitHub path's sync, whose row lookup no longer needs the provider: a
  GitLab owner carries its host and never matches a GitHub one.

  (text, `!12`, `12` or the MR URL), and checkout reads the MR's branch
  and head with `glab mr view`. MRs from forks are refused for now.
- execGlab moves to its own exec-glab.ts with an ExecGlab type, so GitLab
  code no longer imports it from exec-gh. exec-gh exports the shared
  execCli runner.
- normalizeMergeRequest and toJobCheck become normalizeGitLabMergeRequest
  and toGitLabJobCheck.
The runtime keeps a set of hosts glab has confirmed instead of
re-checking every host every 5 minutes. An unknown host is asked again
at each refresh, one local `glab config get`, so a host added with
`glab auth login` shows at the next refresh without a restart.

Routers now ask the runtime only for a GitLab identity, through
getGitLabRepository. getProjectRepository returns the GitHub identity
saved on the project row, which routers must not use: resolveGithubRepo
reads the remote as it is now. A GitLab identity is never saved, so it is
always read fresh.

All these lines changed are just whitespace formating...

This case-drift sweep did not feel useful to add...
I should note that when a workspace has no MR, it costs one more glab mr list of up to 100 open MRs per project refresh, and glab has nothing like gh's free 304 revalidation. If you want it, here it is:

Suggested change
// No GitLab sweep yet. GitLab's branch filter is also case-sensitive, so a
// branch whose case drifted from its MR stays unlinked.
if (repo.provider === "gitlab") return [];
if (repo.provider === "gitlab") {
return this.cachedGitHubFetch(
this.openPullRequestsCache,
`${repo.owner.toLowerCase()}/${repo.name.toLowerCase()}`,
options,
() => fetchOpenPullRequestsFromGlab(this.execGlab, repo),
);
}

It needs this in github-gitlab-query.ts, exported from github-query/index.ts and imported here:

export async function fetchOpenPullRequestsFromGlab(
	execGlab: ExecGlab,
	repository: GitLabRepository,
): Promise<GitHubPullRequestNode[]> {
	const raw = await execGlab([
		"mr",
		"list",
		"-R",
		repository.url,
		"-o",
		"updated_at",
		"-P",
		"100",
		"-F",
		"json",
	]);
	return asArray(raw)
		.map((item) => normalizeGitLabMergeRequest(item, repository))
		.filter((node): node is GitHubPullRequestNode => node !== null);
}

This makes it work for both GitHub/GitLab and is alredy part of the translated sentences (used in other places of the UI for the same action)

I decided to keep getProjectRepository private to avoid future devs randomly using this instead of the resolveGithubRepo which avoids misuse (stale copy):
For a GitHub remote it saves owner, name and URL on the project row, and from then on it returns that saved copy without reading the remote again.

It felt worth the ... 7 more lines, super easy to read anyway ^^

normalizePullRequest, toCheckRunNode and mapReviewDecision and their
GitLab counterparts build the same shapes, so a change to one usually
needs the other. Each now names its twin.

- The two runtime tests share one gitlabProject helper and seed the
  workspace upstream, as the GitHub refresh tests do, instead of mocking
  readWorkspaceRefs.
- glab answers come from one table keyed by subcommand.
- The optional failed job had no effect on the assertion and is gone.
- Shorter example hosts keep each remote-parser case on one line.
