fix(ui): render branch-namespaced repos in the graph selector - #715
Merged
Merged
Conversation
The T17 per-branch graph identity change (921dccd) made `GET /api/list_repos` return `{project, branch, graph}` objects, but the combobox still rendered each entry as a plain string. React threw "Objects are not valid as a React child" (minified error #31), the SPA crashed to a blank page, and every Playwright test failed with "ComboBox button is not visible!". The e2e seeder had the same blind spot: it wrote the required CALLS edges and search-term fixtures into a bare `GraphRAG-SDK` graph, which the analyzer no longer uses, so those fixtures silently landed in an unused graph. Changes: - Add `RepoOption`, `toRepoOption` and `repoLabel` helpers; `toRepoOption` also accepts legacy plain-string entries so the UI degrades gracefully against a mismatched backend. - Select on the composed graph name and display `project`, suffixed with the branch when it is not the default. - Resolve `repo_info` metadata via the parsed project/branch so composed graph keys work the same as bare repo names. - Seed fixtures into the graph `analyze_sources()` actually wrote to.

- This still cannot select an un-migrated legacy graph.
async_get_repos()returns legacy entries withgraphset to the bare graph key (for examplerepo), but the branch-awareAsyncGraphQueryrewrites any barerepoargument tocode:repo:_default; selecting this value therefore queries a different, nonexistent graph. Please make legacy entries addressable through an explicit raw-name/alias path or migrate them before exposing them in the selector.

"Verify auto-scroll and manual scroll in chat" asserted the scroll position 500ms after sending a message. The answer streams in and the scroll is animated, so on slower CI machines the container is still growing when the assertion runs — the test failed all three attempts on firefox while passing locally. Poll until the container settles at the bottom, and allow a sub-pixel tolerance since fractional scroll metrics rarely sum to an exact integer.

- When the UI is pointed at the legacy backend,
analyze_reporeturns nobranchfield (the legacy route returns only{status: "success"}), so this creates an option whose label isproject (undefined)and whose graph iscode:project:_default. That backend created the bareprojectgraph, so the newly created repository cannot be loaded. Fall back to the bare project asgraphwhen the response has no branch, while using_defaultonly for the display branch.
branch: json.branch,
graph: composeGraphName(project, json.branch),
app/src/lib/utils.ts:34
- This preserves legacy graph names as selectable values, but the branch-aware API does not treat a bare value as a raw graph name:
async_get_repos()returns legacy graphs withgraphequal to the bare key, whileAsyncGraphQuerycomposescode:{project}:_defaultfor that same input. Consequently, a legacy repository advertised by/api/list_reposdisplays but selecting it queries a different graph and returnsMissing project. Please migrate/resolve legacy entries before exposing them or make the API honor the raw graph key.
const graph = repo?.graph ?? repo?.project ?? ""
return {
project: repo?.project ?? graph,
branch: repo?.branch ?? DEFAULT_BRANCH,
graph,
…ames
Addresses review feedback on the branch-namespaced graph selector:
- `toRepoOption` now composes the graph name when the backend reports a
project/branch pair without the composed key, so the UI can no longer
show one branch while loading `_default`.
- `projectNameFromURL` mirrors the backend's `urlparse(url).path` parsing.
The previous raw `split('/')` kept any query string, so analyzing
`https://github.com/org/repo?tab=readme` composed a graph name that did
not match the one `analyze_repo` created.
- `waitForAtBottom` now also requires the scroll height to stop growing,
so an auto-scroll that reaches the bottom once and then stops following
the streamed response no longer passes.

- This branch-aware fix is only in the production route, but the endpoint suite is wired to
tests/index.py, whoserepo_info/read routes still constructAsyncGraphQuery(data.repo)and read metadata with the bare name. AfterProjectauto-detects a cloned checkout's branch and writescode:<project>:<branch>, those tests query_defaultand fail (the same stale harness also omits the new branch fields). Update the test app or switch the endpoint tests to the production app so the branch-aware contract is exercised.
# Use the parsed project/branch so full graph keys
# (``code:{project}:{branch}``) resolve the same as plain repo names.
info = await async_get_repo_info(g.project, g.branch)
app/src/App.tsx:149
- This construction assumes the new
/api/analyze_reporesponse always containsbranch, unlike the legacy-backend compatibility handled bytoRepoOption. With an older response that omits it, the option gets an undefined branch andcode:<project>:_defaultas its graph, but that backend created<project>; the create flow then selects a graph that cannot be loaded. Default the display branch, but preserve the bare project asgraphwhen the response has no branch (or have the endpoint return the graph identifier).

graph: composeGraphName(project, json.branch),

- Selecting an un-migrated repository returned by the current
/api/list_reposstill fails here.async_get_repos()represents a legacy bare graph as{ graph: g, branch: "_default" }, but passing that baregraphto the branch-aware endpoints makesAsyncGraphQueryreinterpret it as a project and querycode:{g}:_default, not the existingggraph. Please either migrate/filter these legacy entries before exposing them or add a raw-graph fallback so this selector can actually load every entry it receives.
<SelectItem key={option.graph} value={option.graph}>
app/src/lib/utils.ts:35
- Using
repo.graphverbatim leaves legacy graphs unselectable with the branch-aware backend.async_get_repos()returns a pre-T17 graph as{project: g, branch: _default, graph: g}, butAsyncGraphQueryinterprets that bare value as a project and queriescode:g:_default, so/api/graph_entitiesreturnsMissing projectinstead of the legacy graph. Please make the read path preserve/migrate legacy graph names before exposing this option.

Summary
The e2e suite has been fully red on
stagingsince 2026-05-27 — every Playwright test fails withComboBox button is not visible!. This is not flakiness: the SPA crashes to a blank page on load.Root cause: commit 921dccd (
feat(graph): per-branch graph identity (T17 #651)) changedGET /api/list_reposto return{project, branch, graph}objects, butapp/src/components/combobox.tsxstill rendered each entry directly as a React child. React throws minified error #31 ("Objects are not valid as a React child"), the whole tree unmounts, and nothing renders.Two secondary defects from the same change:
e2e/seed_test_data.pywrote the requiredCALLSedges and search-term fixtures into a bareGraphRAG-SDKgraph, which the analyzer no longer uses. CI logs showedAnalyzer created 0 CALLS edges; after the fix it reports 202.POST /api/repo_infolooked up Redis metadata with the rawrepoargument, so composed graph keys (code:{project}:{branch}) returnedMissing repository. The metrics panel showed0 Nodes / 0 Edges.Changes
