Problem

On a workspace where a rescan takes longer than 15 seconds (a large checkout, a slow disk or a network filesystem), saving a file or finishing an agent turn can break content search. Both paths call WorkspaceEntries.refresh, which rescans every live index and waits up to 15 seconds per index. When that wait runs out, refresh reports WorkspaceSearchIndexScanTimedOut, and WorkspaceEntries invalidates the index it just asked to refresh. The next content search builds a new index from scratch. That build hits the same 15-second wall, and the dialog shows "Failed to search workspace contents in '…'".

The index that was thrown away still worked. fff runs scanFiles() in the background and keeps answering from the previous index until the new scan finishes. A refresh that outlasts the wait leaves a usable finder behind.

Change

WorkspaceSearchIndex.refresh no longer fails when the rescan outlasts the 15-second wait. The rescan keeps running on the live finder, which answers from its previous index until the rescan finishes. refresh() no longer reports WorkspaceSearchIndexScanTimedOut, and its service type drops that error.

This differs from index creation on purpose. #11500 kept the path finder alive after an initial scan timeout, but kept the failure for the content index, because an unfinished first content scan has no complete index to answer from. A refresh has one, since the previous scan stays in place while the rescan runs.

WorkspaceEntries.refresh is unchanged. It still invalidates an entry when acquiring the index fails, including a cached failed build, so a broken index is still cleared.

The write still waits up to 15 seconds for each live index to rescan, so up to 30 seconds when the path and content indexes are both live. That wait is a separate problem and is left alone here.

Scope and approval

Fixes the refresh half of #10917. In the triage comment, @juliusmarminge confirmed the bug and noted "refresh logs + invalidates on ScanTimedOut". #11500 fixed the creation path and closed the issue. The refresh path it named still drops the index on current main.

Verification

New test in WorkspaceEntries.test.ts. It uses a real fff finder on a temp workspace and wraps waitForIndexReady so that every wait after the first build reports "not ready", as a slow disk would. It runs a content search, calls refresh, then searches again. No timers.

• On main the second search fails with WorkspaceSearchIndexScanTimedOut, because the refresh invalidated the index and the rebuild timed out.
• On this branch the second search returns the match.

Real app, production builds of main and this branch on Linux, each on fresh state. The project sits on a loopback FUSE mount that can add 20 ms to each getattr, readdir, open and read, as a stand-in for a slow network filesystem. In a direct fff check on this mount, the content index builds in about half a second with the delay off, and a rescan outlasts 15 seconds with it on. Steps for each build:

1. Search "computeLateFee" in the content search dialog (fast mount).
2. Open src/billing/invoice.ts and switch the mount to slow.
3. Type a comment into the file, which autosaves.
4. Wait 35 seconds, then search "LateFee".

On main, the server logs "Failed to refresh workspace search index" with WorkspaceSearchIndexScanTimedOut for the content index. Step 4 then fails after 16 seconds. On this branch there is no refresh warning, and step 4 returns the match in 6 seconds over the slow mount.

Also run: vp fmt --check and vp lint on both changed files, and tsc-rs --noEmit in apps/server. All pass.

Not checked:

• macOS and Windows. The change is in shared server code with no platform branch.
• A real network filesystem or a cold-cache checkout. The FUSE delay stands in for both.
• The agent-turn trigger (RunFinalizationService). It calls the same WorkspaceEntries.refresh.
• The path index (Files panel, file picker) in the real app. It takes the same refresh() path, and the test covers the content index.

Prior PRs

#11500 by @Michel-Liao kept the path finder alive when the initial scan times out and closed #10917. This PR covers the refresh path, where the finder keeps answering from its earlier scan while the rescan runs. Thanks to @JoergHansmann for reporting #10917.

Related: #22603 by @mikeohuo (open) removes the refresh after agent runs. It changes different files and does not conflict. File saves still refresh either way.

Approvability

Verdict: Approved at e9adc6c

Macroscope's review found this PR approvable — This is a focused server bug fix that keeps the existing workspace search index available when a refresh exceeds its wait timeout, while preserving failure handling for actual refresh errors. A targeted regression test covers the affected path.

Walkthrough

Workspace index refresh now succeeds when a scan exceeds the readiness wait. The scan continues, and searches use the previous index until scanning finishes. A regression test checks search results and confirms that refresh reuses the existing finder.

Changes: Workspace index refresh

Layer / File(s)	Summary
Refresh timeout behavior and search regression test apps/server/src/workspace/WorkspaceSearchIndex.ts, apps/server/src/workspace/WorkspaceEntries.test.ts	refresh no longer reports scan timeouts as failures. The scan continues, and the finder serves results from the previous index until scanning finishes. The regression test checks that a search returns an indexed match and that refresh reuses the existing finder.

The refresh fix is supported, but the regression test should be strengthened because it does not verify search during an active rescan.

Keep the rescan active during the search assertion.

The mock returns false immediately, even if the scan of the small temporary directory has finished. The second search can therefore pass without testing whether the finder serves the previous index during an active rescan. Hold the scan in progress through the second search, and assert that it is still scanning before checking the match. The native readiness method checks scan progress rather than returning a fixed timeout result. (github.com)

Verified in a real dev environment

verified the file-save refresh fix as-is at af0aefcd2f4b8864951ff3af1a76df92cce5904c, against github/main at 6575ce3250. no pr changes or pushes.

ran vp i and one background vp run dev at a time, with separate state. drove the web app with the repo's playwright and /usr/bin/google-chrome. created the project and threads through the app and ran real codex gpt-6.1-sol turns. the workspace was a real t3code checkout on a fuse passthrough mount with switchable source-metadata delays, not a mocked index.

• main: searched WorkspaceSearchIndexScanTimedOut successfully, enabled slow filesystem operations, then edited the file in the app. both live indexes logged WorkspaceSearchIndexScanTimedOut; the next content search showed Failed to search workspace contents.
• pr: repeated the same save and query against the same workspace. search returned all 10 matches in 3 files with delays still enabled. no Failed to refresh workspace search index warning.
• nearby behavior: the file picker found and opened WorkspaceEntries.ts with delays enabled. search still returned the original matches after a real codex edit. with delays removed, another codex edit appeared in search at line 564, so later refreshes still publish new content.
• blacksmith: 21 focused workspace tests passed. check:changed passed format, lint, knip, graphql generation, affected typechecks, and both workspace test files, against the original pr base. existing pr checks: all 27 contexts successful or skipped.

main after the slow save:

pr after the same slow save:

condensed recording of the real save, wait, and search. frames were sampled and accelerated; this is not a latency benchmark:

command transcript, server warnings, provider run records, and check summary

Not verified

clean turn finalization under the deliberately serialized slow mount: the codex turn saved its edit and subsequent content search worked, but git-status refresh timed out with RunFinalizationRefreshError / GitManagerError. normal-speed finalization recovered on the next turn. the slow search also temporarily blocked server responses; this pr does not establish a responsiveness improvement.

native ios/android, the electron shell, macos/windows, remote/relay/tunnel connections, an actual network filesystem, and initial-scan timeout behavior were not exercised on this linux vm.
