File Changes

1. src/service/coderag.ts 🐞 Bug fix +22/-0

Add concurrency control for index operations

• Added waitForTermination() async method to wait for in-flight index operations to settle
• Method intentionally swallows errors since original caller receives rejection through promise
• Modified ensureLoadedState() to call waitForTermination() before checking disk state
• Added double-check pattern to prevent spawning duplicate index runs during concurrent operations

🐞 Bugs (2) 📘 Rule violations (1) 🔗 Cross-repo conflicts (0)

Context used
✅ Compliance rules (platform): 9 rules

Grey Divider


Action required

1. No tests for waitForTermination() 📘 Rule violation ▣ Testability
Description
Indexing coordination was changed by adding waitForTermination() and calling it from
ensureLoadedState(), but there is no test that exercises this new in-flight index waiting
behavior. This risks regressions where a query/lookup can race an in-progress index and reintroduce
duplicate index runs or inconsistent loaded state.
Code

src/service/coderag.ts[R84-109]

Evidence
PR Compliance ID 269570 requires tests for modified indexing behavior. The PR introduces new
indexing coordination logic (waitForTermination() and a new call site in ensureLoadedState()),
but the existing CodeRag tests shown do not cover a scenario where an index is in-flight and another
operation triggers ensureLoadedState() to wait (they cover waiting on an external lock and
concurrent index() calls, not the new in-process termination wait).

Rule 269570: Add tests for new indexing, retrieval, transport, or MCP behavior
src/service/coderag.ts[84-123]
src/test/coderag.test.ts[167-233]

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
`CodeRag.ensureLoadedState()` now waits for an in-flight index operation via the new `waitForTermination()` helper, but the test suite does not include coverage for this new coordination behavior.

## Issue Context
This change is part of indexing lifecycle/locking behavior (index creation/update coordination). Per compliance, modified indexing behavior must be covered by automated tests with assertions that would fail if the behavior is removed.

## Fix Focus Areas

2. Unbounded index wait 🐞 Bug ☼ Reliability
Description
ensureLoadedState() now awaits waitForTermination(), which awaits activeIndexPromise without any
timeout; if an index operation never settles, lookups/queries that need loaded state can hang
indefinitely. Index operations include potentially long-running/remote vectorStore calls, while the
repo’s lock-wait path already has a timeout but is bypassed by this in-process wait.
Code

src/service/coderag.ts[R103-106]

Evidence
The new code unconditionally blocks ensureLoadedState() behind activeIndexPromise with no time
bound, while the existing lock-based wait has an explicit timeout. Indexing includes async vector
store operations that can take arbitrarily long, so an unbounded await can stall all state-dependent
calls.

src/service/coderag.ts[68-123]
src/store/index-lock.ts[56-75]
src/indexer/indexer.ts[163-227]

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
`CodeRag.ensureLoadedState()` now calls `await this.waitForTermination()`, and `waitForTermination()` awaits `activeIndexPromise` with no timeout. If the index promise never resolves/rejects (e.g., a stuck vector store call), all operations that require `ensureLoadedState()` can block indefinitely.

## Issue Context
- Indexing work includes `vectorStore.reset/upsert/deleteByNodeIds` which are async I/O and may stall.
- The codebase already has a bounded-wait pattern via `IndexLock.waitForRelease()` using `locking.timeoutMs`, but `waitForTermination()` does not apply any similar bound.

## Fix Focus Areas
- src/service/coderag.ts[68-123]
- src/store/index-lock.ts[56-75]
- src/indexer/indexer.ts[163-227]

## Suggested fix
- Add an optional `timeoutMs` parameter to `waitForTermination()` (defaulting to `this.config.locking.timeoutMs`).
- Implement the timeout with `Promise.race([activeIndexPromise.catch(...), timeoutPromise])`.
- On timeout, either:
 - throw an `IndexingError` explaining that an in-flight index did not terminate in time, or
 - log and fall back to the disk-lock wait path (e.g., `await this.indexer.waitForUnlockedState()`), so callers get a bounded failure mode consistent with other lock waits.

Remediation recommended

3. Index errors not logged 🐞 Bug ◔ Observability
Description
waitForTermination() catches and ignores rejections from activeIndexPromise without emitting any log
entry. Callers blocked behind a failed index run lose the error signal on this path, making
indexing-related outages harder to diagnose.
Code

src/service/coderag.ts[R90-95]

Evidence
The catch handler is intentionally empty, so failures are neither propagated nor logged, whereas
related lock/index coordination code logs exceptional conditions (timeouts, stale lock removal).

src/service/coderag.ts[84-96]
src/store/index-lock.ts[67-70]
src/store/index-lock.ts[129-137]

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
`waitForTermination()` swallows `activeIndexPromise` rejections with an empty catch handler. This removes any observability for callers that are waiting behind a failed index operation.

## Issue Context
Other coordination paths (e.g., index lock timeouts / stale lock cleanup) emit warnings, but this path stays silent even on failure.

## Fix Focus Areas
- src/service/coderag.ts[84-96]
- src/store/index-lock.ts[67-70]
- src/store/index-lock.ts[129-137]

## Suggested fix
- In `waitForTermination()`’s catch handler, log at `warn` (or `error`) with the caught error and relevant context (e.g., `repoPath`, operation type if available).
- Keep swallowing if that behavior is desired, but ensure the failure is visible in logs.

Code Review

This pull request updates dependency configurations in package-lock.json, adjusting peer dependency flags for various packages. In src/service/coderag.ts, a new waitForTermination method is introduced to await any in-flight index operations, and ensureLoadedState is updated to call this method to prevent duplicate index runs. There are no review comments provided, and I have no additional feedback on these changes.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

Pull request overview

This PR introduces additional in-process synchronization in CodeRag so that state-loading operations don’t race with an in-flight indexing operation, alongside an automated regeneration/update of package-lock.json as part of a DevPulse recovery.

Changes:

  • Add a helper to await completion of any active index promise before ensureLoadedState() checks persisted state.
  • Update ensureLoadedState() to wait for in-flight indexing to settle to avoid inconsistent/duplicated index behavior.
  • Regenerate/update package-lock.json, adding/removing various peer metadata flags and introducing a couple of new optional packages.

Reviewed changes

Copilot reviewed 1 out of 2 changed files in this pull request and generated 2 comments.

File Description
src/service/coderag.ts Adds an “await active index” step before loading persisted state to reduce in-process races during indexing.
package-lock.json Automated lockfile update (dependency metadata churn, including peer flags and a few new optional packages).
