Search gave wrong answers and could hang or crash the server. maxResults limited each file instead of the whole search, a session said "complete" while Excel and DOCX searches were still adding results, a search stopped by its time limit, stop_search or maxResults said "✅ Search completed.", a ripgrep that couldn't start crashed the server, and a process that ran a search never exited on its own. This PR gives search-manager.ts one completion point, one total cap and one outcome per search: completed, timed_out, stopped, max_results, partial or failed. Both answers (start_search, get_more_search_results) are built from that outcome in one place, src/handlers/search-answers.ts, with every phrase in its SEARCH_WORDS table; each ends saying how the search ended. Answers change where the old one was wrong or didn't say how the search ended; the table below has each. The tool descriptions stay as they were; the input schemas now say the search numbers are whole and in range.

What this fixes

Problem Fix
A process that ran a search never exited on its own. The 5-minute cleanup timer is unref'd, and dispose() stops it.
maxResults: 2 returned 6 matches, and maxResults: 50 across 100 files returned 100. maxResults caps the total; it went to ripgrep as a per-file limit.
searchFiles returned 350 paths for 250 matches and never got past 100. It waits for the session to finish instead of re-reading the same page.
A session reported "complete" while Excel and DOCX searches were still adding results. It is complete only once every source has finished.
A content search for "report.json" was cut at 1.5 s and reported complete. The 1.5 s limit applies to exact file-name searches only.
A search stopped by its time limit, stop_search or maxResults said "✅ Search completed." Its answer says what stopped it, and that results may be incomplete or there may be more.
A search where some files couldn't be searched (an Excel or DOCX file or folder, the Excel or DOCX search as a whole, ripgrep ending or failing after matches) said "✅ Search completed.", and any ripgrep error gave the permissions warning. The answer says what couldn't be searched. Only permission errors give the permissions warning, from ripgrep and the Excel/DOCX search alike.
A ripgrep that ended without a word (exit code 3, a signal), or with an error that isn't about permissions, answered "No matches found." when nothing was found. The search failed, and the answer says why.
A bad glob next to an Excel or DOCX search answered that search's matches, with the permissions warning. ripgrep's error is the answer.
start_search answered "✅ Search completed." for a search that had already failed. It answers with the failure, as get_more_search_results does.
An empty page said "Showing results 5-4"; an empty page of a running search said "No results yet" with results there; every page of a running search said "More results available". Empty pages say what there is, and "More results available" comes only when more are there.
Context lines looked like matches, and the two tools counted results differently. Context rows look unlike matches, and both tools count alike.
length: 0, offset: 0.5, maxResults: 1.5, contextLines: 1.5 and timeout_ms: -5 were taken, with odd results. Search numbers must be whole and in range; the input schemas say integer and the minimum.
A finished search's runtime kept growing on every read, and a finished session read only from its end (a negative offset) was dropped by the 5-minute cleanup as if nobody read it. The runtime stops where the search ended, and every read keeps the session.
The user's ripgrep config file (RIPGREP_CONFIG_PATH) changed the results. ripgrep runs with --no-config.
Path globs such as src/*.ts never matched. ripgrep runs in the search root, not in Desktop Commander's working folder.
A ripgrep that couldn't start crashed the server. The old answer "Failed to start ripgrep process", with the reason in the log.
For Excel and DOCX, report.xlsx|memo.docx skipped the Excel search, and !secret* still read secret.xlsx. Each alternative is checked, and ! exclusions are honored.
A file search ignored its filePattern, ! exclusions included. A file search keeps to its filePattern.
A literalSearch file search for report[1].txt also found report1.txt. The pattern is matched as the exact name.
Excel and DOCX files didn't follow filePattern's globs: **/*.xlsx found nothing. One glob matcher for text files and Office files.
includeHidden: true didn't reach Excel and DOCX files in hidden folders. The Office walkers enter hidden folders with includeHidden.
An Excel or DOCX file given as the search path wasn't searched when filePattern named other files (*.ts) or only left others out (!*.tmp), where a text file is. A filePattern of only ! alternatives kept no Excel or DOCX file when the search path was named like one. main does the same. As ripgrep does: the search path itself is searched whatever filePattern says, and only ! alternatives keep every file they don't leave out.
An invalid regex, an invalid glob or a missing path answered "No matches found". The error is answered, in the forms the tools already use.
A timeout_ms above 2^31−1 ms stopped the search at once. The timer is capped at 2^31−1 ms.
A search stopped by its time limit or stop_search, after ripgrep reported unreadable folders and before it had found anything, answered "encountered an error". A stop of ours is not a failure.

Where to look

  • src/search-manager.ts collectMatch(), finishSource() (pendingSources), outcomeOf() (SearchOutcome): the one total cap, the one completion point and the one outcome, the core of the change.
  • src/search-manager.ts noteRipgrepErrors(), noteUnsearched() (UnsearchedKind): what couldn't be searched, by kind, with a count and the first example; permission errors apart from other errors.
  • src/handlers/search-answers.ts SEARCH_WORDS, startSearchAnswer(), searchResultsAnswer(): both answers, built from the outcome; src/handlers/search-handlers.ts calls them.
  • src/tools/schemas.ts wholeNumber(): the checks on offset, length, maxResults, contextLines and timeout_ms.
  • src/search-manager.ts whenStarted(), stopRipgrep, isExactFilenameSearch(), LONGEST_TIMER_MS: starting and stopping ripgrep, and the time limits.
  • src/search-manager.ts ripgrepGlobMatcher, filterOfficeFiles, officeWalkEnters: file-search and Office matching with ripgrep's glob syntax and its rules (the search path itself, only ! globs); hidden folders only with includeHidden.
  • outcome goes to the internal structuredContent (never sent to the client) and to telemetry's search_session_completed, where wasIncomplete now means outcome partial. src/tools/filesystem.ts searchFiles() waits with waitForCompletion().
  • Tests: test/test-search-*.js, with test/helpers/search.js and test/helpers/run-node.js. test-search-timeout.js stalls ripgrep without a product hook. test-search-outcome.js has a case for each answer, with a scripted ripgrep (test/fixtures/ripgrep-scripted.mjs) and a folder the Office search can't list (test/fixtures/unlistable-folder-hooks.mjs).

Answers that change

Before After
maxResults: 2: up to 6 matches, then "✅ Search completed." at most 2 in total, then "Stopped at maxResults (2): there may be more."
"complete" while Excel/DOCX matches were still arriving complete only after Excel/DOCX finish
A content search cut at 1.5 s and reported complete it runs to its end or its timeout_ms
Stopped by its time limit (timeout_ms: 1000, or the 1.5 s of an exact file-name search): "✅ Search completed." "⏱️ Stopped after 1000 ms: results may be incomplete." ("… 1500 ms …" for the 1.5 s)
Stopped by stop_search: "✅ Search completed." "⏹️ Stopped on request: results may be incomplete."
Stopped by the time limit or stop_search after unreadable folders, with nothing found yet: "encountered an error" the time-limit or stop_search line above, not an error
Some files couldn't be searched: "✅ Search completed.", with the permissions warning for any ripgrep error "⚠️ Completed, but some files couldn't be searched: …" with the reasons, joined with "; ", e.g. an Excel file couldn't be read (<path>), the Excel search failed (<why>), a folder couldn't be listed for the DOCX search (<path>: EIO), ripgrep stopped unexpectedly (exit code 3), ripgrep: <path>: The device is not ready. (os error 21)
Only files or folders it may not read: ripgrep's gave the permissions warning, in get_more_search_results only; the Excel/DOCX search's gave nothing "✅ Search completed." and "⚠️ Warning: Some files were inaccessible due to permissions. Results may be incomplete." from both tools, for ripgrep's and the Excel/DOCX search's alike
ripgrep ended unexpectedly, nothing found, nothing on stderr: "No matches found." an error: "Search session … failed: ripgrep stopped unexpectedly (exit code 3)." (or "(signal SIGKILL).")
A ripgrep error that isn't about permissions, nothing found: "No matches found." and the permissions warning an error: Search session … encountered an error: rg: <path>: The device is not ready. (os error 21)
A bad glob in filePattern next to an Excel/DOCX search: its matches and the permissions warning an error: "Search session … encountered an error: rg: error parsing glob '{a': …"
start_search on a search that had already failed: "✅ Search completed." the failure answer get_more_search_results gives, as an error
Results changed by the user's ripgrep config the config is ignored
src/*.ts: no matches; Office | and ! ignored src/*.ts matches; Office | and ! honored
A ripgrep that can't start: the server crashed "Failed to start ripgrep process"; the reason goes to the log
A file search with a filePattern: the filePattern ignored only files matching both; ! leaves files out
Excel/DOCX by filePattern globs (**/, paths, [...], ?, {a,b}): not selected selected as text files are (case still ignored)
literalSearch file search for report[1].txt: found report1.txt finds report[1].txt
An invalid regex: "No matches found" start_search (if ripgrep has failed by then) or get_more_search_results: "Search session … encountered an error: rg: regex parse error: …"
A missing path: "No matches found" start_search: "Error starting search session: ENOENT: no such file or directory, stat ''"
A file search with an invalid glob: "No matches found", or a JavaScript regex error "Search session … encountered an error: rg: error parsing glob '…': …"
timeout_ms above 2^31−1 ms (about 24.8 days): stopped at once runs to its end
An empty page past the end: "Showing results 5-4" and "No results in this range." "No results at offset 5 (5 in total)."; no "Showing results" line on any empty page
An empty page of a running search: "No results yet, search is still running..." "Still running: 5 results so far, none at offset 10 yet."
Every page of a running search: "📖 More results available. Use get_more_search_results with offset: …" only when more are found already; else "Still running: more may come."
A context row: 📄 <file>:1 - before, as a match <file>:1 · before
The count: start_search "Total results: 1" (matches only); get_more_search_results "Total results found: 3 (1 matches)" both "Total results: 1 match (3 rows with context)"; without context rows, "Total results: 5 matches"
length: 0, offset: 0.5, maxResults: 1.5, contextLines: 1.5, timeout_ms: -5: taken (length: 0 answered "Showing results 0--1" and "No results in this range."; timeout_ms: -5 stopped the search at once) rejected, as an error: "Invalid arguments for get_more_search_results: [ … "message": "length must be a whole number of at least 1" … ]"; likewise "offset must be a whole number" and "maxResults must be a whole number of at least 0" (contextLines, timeout_ms the same). 0 keeps its meaning
A finished search's runtime (get_more_search_results, list_searches): grew on every read the time the search ran
list_searches, a search with an invalid regex: "✅ COMPLETED" "❌ ERROR", as for every search that failed
includeHidden: true: .archive/old.xlsx missed found; includeHidden: false unchanged
An Excel or DOCX file as the search path, with a filePattern that names other files (*.ts) or only leaves others out (!*.tmp): no matches its matches, as for a text file
Excel/DOCX under a search path named like one (a folder book.xlsx), with a filePattern of only ! alternatives: none searched every file they don't leave out

📝 Walkthrough

Walkthrough

Search sessions now coordinate ripgrep, Excel, and DOCX sources. They track outcomes, failures, time limits, result caps, and context rows. Shared handlers format search responses, and searchFiles waits for completed results. Tests cover filtering, completion, errors, and lifecycle behavior.

Changes

Search sessions

Layer / File(s) Summary
Session startup and lifecycle
src/search-manager.ts
Sessions track active sources and completion. Timeouts, stopping, and disposal stop all sources. The manager exposes session state and supports waiting for completion.
Source filtering and result collection
src/search-manager.ts
Excel and DOCX searches stream matches and report unreadable paths. Ripgrep applies file-pattern filters. Shared collection enforces the result limit and retains trailing context.
Response construction and searchFiles completion
src/tools/schemas.ts, src/handlers/search-answers.ts, src/handlers/search-handlers.ts, src/tools/filesystem.ts, test/test-client-results.js
Search arguments require whole-number limits and valid pagination values. Shared answer builders format status and pages. searchFiles waits for completion and returns file paths.
Pattern, literal, and hidden-entry tests
test/test-search-file-pattern.js, test/test-search-files-file-pattern.js, test/test-search-files-literal.js, test/test-search-files.js, test/test-search-hidden*.js, test/test-search-office-any-folder.js, test/test-search-ripgrep-config.js
Tests cover pattern selection, literal filenames, hidden entries, Office searches, ripgrep configuration, and file-search results.
Outcome, timeout, and failure tests
test/test-search-outcome.js, test/test-search-timeout.js, test/test-search-long-timeout.js, test/test-search-office-completion.js, test/test-search-process-exit.js, test/test-search-stopped-not-failed.js, test/test-search-failed.js, test/test-search-without-ripgrep.js, test/fixtures/*, test/helpers/module-hooks.js, test/helpers/run-node.js, test/repro/test-search-child-config-lock.js
Tests and fixtures cover completion, timeouts, result limits, partial and failed searches, pagination, process exit, startup failures, and config-lock contention.
Search behavior regression tests
test/test-search-code*.js, test/helpers/search.js
Tests assert match counts, context, completion, error responses, and result limits using shared search helpers.

Merge Risk: 🔵 Low · up to 6b18b

Searches with context can report a total that leads clients to stop paging too early. Align the two response fields; this bounded issue does not otherwise block merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 6b18b

Searches retain their existing filesystem access checks and gain stronger result limits and clearer outcomes. One failure-containment concern remains: the file-search compatibility function now waits for process completion without an independent return deadline if cancellation fails.

Retained concerns

  • Low · reliability · inferred: The new searchFiles completion wait removes the previous bounded polling exit. Its 30-second timer requests cancellation but does not settle the wait independently. If child shutdown fails and no terminal callback occurs, the caller can remain pending indefinitely. SIGTERM-only termination predates this PR; the newly introduced exposure is the caller's dependence on successful termination.
Security review details

Security Blast Radius

  • inferred — The inspected security-relevant scope is filesystem reading beneath validated search roots and resource consumption in the owning server process and ripgrep child. The changes do not establish a new identity, tenant, or infrastructure-authority transition.

Trust Boundaries and Controls

  • observed — Path validation resolves the requested root to its canonical target and checks allowed-directory policy before returning it. User patterns are passed as direct process arguments rather than shell commands. These inspected controls counter a root-validation bypass or shell-injection interpretation of the working-directory change.

Resilience and Maintainability Implications

  • observed — Office cancellation is logical result finalization, not immediate resource termination: an in-flight file operation may continue until the next stop check, while its subsequent results are discarded. The inspected stop test explicitly exercises this distinction but does not demonstrate resource drainage before completion.

Hardening Proposals

  • proposed — Define separate result-finalization and resource-drainage guarantees, and give completion-waiting callers an independent bounded cancellation outcome. Where supported, confirm child exit and escalate unsuccessful termination rather than treating signal delivery as proof of cleanup.

ripgrep matches a glob that contains a '/' ("src/*.ts", "sub/*") against
the path below its working directory, and it ran in the server's working
directory, so such a filePattern or file-search pattern matched nothing
under the search path. ripgrep now runs with the search root as its
working directory when the root is a directory.

test-search-without-ripgrep.js now gets past its ripgrep cases
(searchFiles("sub/*")) and fails where ripgrep can't be started, fixed in
the next commit; test-search-file-pattern.js still fails on "!" for the
Office searches.

…D45)

When the bundled ripgrep could not be started (a corrupt or wrong-platform
download), spawn() reported ENOENT/EACCES in an 'error' event on the next
tick. startSearch() had already thrown "Failed to start ripgrep process"
because the pid was missing, before any 'error' listener existed, so Node
rethrew the event as an uncaught exception and the server exited (in the
test, the process running the searches died and left its config lock
behind). startSearch() now waits for ripgrep's 'spawn' or 'error' event
(whenStarted) and start_search reports "Failed to start ripgrep: spawn
<path> ENOENT"; searchFiles() falls back to its Node.js walk.

test-search-without-ripgrep.js passes.

filePattern is a "|"-separated list of globs, and a "!" alternative
leaves files out, as ripgrep applies it to text files. The Excel and DOCX
searches checked the whole filePattern string: "report.xlsx|memo.docx"
skipped the Excel search while "!*.xlsx" ran it, and their file filter
took "!secret*" as a name to include, so excluded workbooks and documents
were searched. Each alternative is now checked on its own
(targetsOfficeFiles): an Office search runs when an alternative that is
not a "!" targets its extensions, and filterOfficeFiles() leaves out the
files a "!" alternative matches - by name, or with a '/' by the path
below the search root, directories included - as ripgrep does.
filePatternAlternatives() splits the pattern for ripgrep and the Office
searches alike.

test-search-file-pattern.js passes.

…g (review)

Review on the stack: "should not return any new info to the user".
get_more_search_results no longer adds the "⚠️ Stopped at maxResults" and
"⚠️ Timed out" notes, and its description no longer lists them. maxResults
still caps the total and the time limit still stops every source (the fixes);
maxResultsReached and timedOut stay in the internal structuredContent.

A ripgrep that can't be started answers "Failed to start ripgrep process"
again; why it couldn't start goes to the log. An Excel or DOCX search that
fails as a whole is logged too (it was only sent to telemetry), and the search
still answers with the other sources' matches.

test-search-without-ripgrep.js checks the old answer and the logged reason,
test-search-office-completion.js makes ExcelJS unloadable in a child process
and checks the log, and test-client-results.js checks a search stopped at
maxResults over stdio; each fails on the layer before this commit.

In a full test run, test-search-without-ripgrep.js took 60.8 s and failed
(its child was killed at 60 s), then its process died of ECOMPROMISED
("Unable to update lock within the stale threshold"). The test searches
in-process first, and each search's telemetry capture starts a locked config
write (the client id), fire-and-forget. It then started its child with
spawnSync, which freezes the test process: when one of those writes held the
config lock at that moment, it kept holding it for the child's whole run, the
child's own config writes waited on it until it went stale (30 s) or failed,
and when spawnSync returned the test process found its lock taken over and
died. test-search-office-completion.js starts its child the same way.

Both now start the child with runNode() (test/helpers/run-node.js): an async
spawn that resolves with what spawnSync returned, same 60 s timeout, same
assertions. The test process keeps running, so its write finishes and
releases the lock. No product code changes.

repro/test-search-child-config-lock.js runs both tests with a preload
(fixtures/config-lock-at-child-spawn.mjs) that holds the config lock whenever
the test starts a Node.js child and releases it 200 ms later on a timer, so
the lock is held at that moment every run. With the tests of the commit
before, they are held up 30 s or more (REPRODUCED); here they finish in
seconds (NOT REPRODUCED).

A file search with a filePattern returned every file that either the pattern
or the filePattern matched: pattern "auth" with filePattern "*.ts" also
returned auth.md, and with "!*.md" auth.md was still there. ripgrep got both
as globs of one list, where any matching glob lets a file in, and the pattern's
glob came last, so it won over a "!".

The pattern's glob now comes first and filePattern's "!" alternatives after
it, so they leave files out. A file ripgrep lists must also match one of the
other alternatives, checked on ripgrep's results by a matcher for ripgrep's
globs (name or path below the search path, *, ?, **, [...], {a,b}; the same
as ripgrep's --glob/--iglob on 44 glob/case combinations). ignoreCase applies
as it does to the pattern. Content searches are unchanged.

test-search-files-file-pattern.js (9 cases) fails 8 of 9 on
1fd0450 (the case without filePattern passes), passes here.

…ing (#768)

A file search with literalSearch: true still took its pattern as a glob:
"report[1].txt" found report1.txt ("[1]" a character class) and not
report[1].txt, and "{a}" found nothing. ("Literal (literalSearch=true):
Patterns are treated as exact strings".) literalSearch only reached ripgrep
for content searches (-F); a file search's pattern always went to --iglob as
it was.

With literalSearch the pattern's glob characters (* ? [ ] { }) now reach
ripgrep each in a class of its own ("[[]"), so they match themselves: an exact
file name when the pattern has an extension (as without literalSearch, also for
the exact-name time limit and early stop), else a part of a name. Without
literalSearch the pattern is a glob as before.

test-search-files-literal.js (5 cases) fails 3 of 5 on the commit before (the
two glob cases pass), passes here.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
An invalid regular expression and a path that doesn't exist both answered
"No matches found … Some files were inaccessible due to permissions".
ripgrep's own report ("rg: regex parse error", "rg: <path>: … cannot find")
was dropped as a system message, and its exit code 2 taken for files it
couldn't read. A root that couldn't be stat'ed was left to ripgrep to report.

- A missing (or otherwise unreadable) search path: start_search answers with
  the error it gives when a search can't start ("Error starting search
  session: ENOENT: no such file or directory, stat '<path>'").
- A content search whose ripgrep exits 2 having printed nothing (with --json it
  prints a line for each file it searches and a summary) could not search at
  all: get_more_search_results answers with the error it gives for a failed
  search ("Search session … encountered an error: rg: regex parse error: …").
  A search that met unreadable files still ends with its results and the
  permissions warning; a file search, which prints only the names it finds,
  is not judged by its output.

test-search-failed.js (4 cases) fails 3 of 4 on the commit before (a valid
search passes), passes here.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
A content search's Excel and DOCX part ignored most of a glob filePattern:
"**/*.xlsx" found no workbook at all, not even in the search path, and
"sub/*.xlsx", "[ns]????.xlsx" or "{a,b}.xlsx" found none either, while the
text files of the same search matched them. The Office searches matched
filePattern's alternatives against file names only, with '*' as the only
wildcard (their "!" alternatives had a path-aware matcher of their own).

They use the file-search matcher now (ripgrepGlobMatcher: ripgrep's globs on
the name or the path below the search path), for their alternatives and their
"!" ones, still ignoring case. It is the one glob matcher for what ripgrep
doesn't select itself; the Office code's own two are gone.

test-search-file-pattern.js pinned the old matching: its cases for a "/" glob,
"[...]"/"?" and "{a,b}" expected no Excel/DOCX file ("ripgrep only"). They now
expect the files the globs match (sub/deep; notes and Shout, case ignored).

test-search-office-any-folder.js (4 cases) fails 4 of 4 on the commit before,
passes here; test-search-file-pattern.js fails its 3 updated cases there,
passes here.

… at once (#768)

A search with timeout_ms 3000000000 (or anything past 2^31 - 1 ms, ~24.8
days) stopped almost at once, with part of its results (240 of 1000) and
"Timed out": Node fires a longer setTimeout delay after 1 ms.

The time limit's timer waits at most 2^31 - 1 ms: past that a search runs
until it ends, as it would under any limit that long.

test-search-long-timeout.js (timeout_ms 3000000000 and 2^31) fails both on the
commit before (0 and 240 of 1000 matches, timedOut), passes here.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
A file search for an exact name in C:\Windows, with no timeout_ms (1.5 s by
default for exact names) and earlyTermination false, answered "Search session …
encountered an error: rg: C:\Windows\WUModels: Access is denied. (os error 5)
…" with 0 results. ripgrep stopped by the time limit ends without an exit code,
and a search ending without one, with anything on stderr (here unreadable
folders) and no match, was taken for a failed one. The same for stop_search and
maxResults.

A stop of ours (stopRipgrep, now also used by the exact-name early stop) is
recorded, and an end without an exit code after it is no failure: the search
answers as a time-limited search does at this layer (completed, with what it
found). The 1.5 s default for exact names is upstream's and stays.

test-search-stopped-not-failed.js: a stand-in ripgrep (fixtures, via a preload
in a child process) reports a folder it may not read and keeps searching; a 1 s
time limit stops it. Fails on the commit before ("encountered an error: rg:
private: Access is denied"), passes here.

…768)

A file search with an invalid glob, as its pattern ("report[") or in its
filePattern ("!{a"), answered "No matches found": ripgrep's "rg: error parsing
glob '…'" was dropped as a system message and its exit code 2 taken for files
it couldn't read. An invalid filePattern alternative other than "!" ("[z-a].txt")
answered "Error starting search session: Invalid regular expression: …": since
the fix that makes a file search keep to its filePattern, those alternatives
are matched by ripgrepGlobMatcher, not by ripgrep.

- Those alternatives now also reach ripgrep, as --pre-globs: ripgrep parses them
  (an invalid one is its error, as for any glob) but never applies them without
  --pre. The matcher leaves a glob ripgrep rejects to ripgrep's error.
- A file search whose ripgrep exits 2 with nothing printed and "error parsing
  glob" on stderr answers with that error ("Search session … encountered an
  error: rg: error parsing glob 'report[': …"), as a content search already
  does. A file search that finds nothing among unreadable folders still ends
  normally: a file search prints only the names it finds.

test-search-failed.js: its 3 new file-search cases fail on the commit before
(two "No matches found", one "Invalid regular expression"), its other 6 pass;
all 9 pass here.

…ders (#768)

start_search's includeHidden: true includes hidden files. The Excel and DOCX
searches, which walk the files themselves, never entered a folder whose name
starts with '.' whatever includeHidden said: a workbook in .archive/ was not
found while ripgrep, run with --hidden, searched the text files next to it.
The walkers now enter hidden folders when includeHidden is true, as ripgrep
does; node_modules stays skipped. With includeHidden false nothing changes
(hidden files matched by a glob still show, as decided).

test-search-hidden.js had pinned the old walk ("ignore includeHidden"); its
includeHidden: true expectations for the Office searches now include the
files in .hidden-dir, its includeHidden: false cases are unchanged. It fails
on the commit before ("content search, filePattern "*.xlsx|*.docx",
includeHidden: true") and passes here.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
The Excel and DOCX searches select their files by filePattern the way
ripgrep's globs select text files, except in two cases:
- A file given as the search path: ripgrep searches a file it is given
  whatever its globs say, but the Office filter applied the pattern to
  it. start_search on budget.xlsx with filePattern "!*.tmp", "*.ts" or
  "!budget*" answered no matches, where a text file answers its matches.
- A pattern made only of "!" alternatives: ripgrep keeps every file they
  don't leave out, but the Office filter needed an alternative to match,
  so it kept none (a folder named like an Excel file runs the Excel search
  without a pattern that targets Excel files).

filterOfficeFiles() now keeps the search path itself, and with only "!"
alternatives, keeps every file they don't leave out. Upstream main has
both: its filter keeps a file only when an alternative matches its name,
and it reads "!*.tmp" as a name starting with "!".

test-search-file-pattern.js searches notes.txt, notes.xlsx and
notes.docx, each given as the path, with "!*.tmp", "*.ts" and "!notes*";
and a folder book.xlsx with "!secret*". On the commit before, the 6
Office cases answer no matches (the text ones pass), and the folder case
finds nothing instead of notes.xlsx. Here they pass, Windows.

test-search-without-ripgrep.js, test-search-stopped-not-failed.js and
test-search-office-completion.js (and the repro test-search-child-config-lock.js,
which runs two of them) failed on Node 20.0-20.5 (and 18.18, 19): their
preloads imported register from node:module, which Node has only from 20.6 /
18.19, and the child process failed to start ("does not provide an export
named 'register'").

test/helpers/module-hooks.js hookArgs(hooksUrl) gives the Node options that
install a hooks module in a child: module.register() from an --import preload
where Node has it, else --experimental-loader. The two fixture preloads become
hooks modules (unusable-ripgrep-hooks.mjs, ripgrep-still-searching-hooks.mjs)
and the three tests start their child with hookArgs().

On Node 20.5.1 the three tests fail on the commit before and pass here. They
pass on 18.18.2, 19.9.0, 20.0.0 and 20.5.1 (loader flag) and on 18.19.0,
20.6.0, 22.15.0 and 24.18.0 (register()), on Windows.

mihailt and others added 5 commits October 5, 2026 16:38
What the AI saw: a search that its time limit, stop_search or maxResults
stopped, and one where some files couldn't be searched, all ended with
"✅ Search completed."; an empty page said "Showing results 5-4"; a running
search said "More results available" with none there; a ripgrep that died
without a word looked like "No matches found"; context lines looked like
matches; and the two tools counted results differently.

test-search-outcome.js has a case for each answer that changes. Searches
that need ripgrep to do something particular run with a scripted stand-in
(fixtures/ripgrep-scripted.mjs, picked by ripgrep-still-searching-hooks.mjs),
and a folder the Office search can't list comes from
unlistable-folder-hooks.mjs.

The tests that pinned the old answers take the new ones:
test-client-results.js (a search cut at maxResults),
test-search-office-completion.js (a partly failed search), and
test-search-failed.js accepts the failure from start_search too. The
session's stop flags become one outcome in its structuredContent (internal:
never sent to the client), which test-search-timeout.js, -long-timeout.js,
-stopped-not-failed.js and the Office test read.

…hich (#768)

What the AI saw: a search that its time limit, stop_search or maxResults
stopped, or one where an Office file, the Office package or a folder
failed, or one whose ripgrep ended after matches, all said "✅ Search
completed."; a ripgrep that died without a word looked like "No matches
found."; a bad glob next to an Office search looked like results plus the
permissions warning; empty pages said "Showing results 5-4" or "No results
yet" with results there; "More results available" came on every page of a
running search; context lines looked like matches; the two tools counted
differently; start_search called a search that had already failed
completed.

Root cause: how a search ended was spread over flags (wasIncomplete,
timedOut, maxResultsReached, isError) that each answer read its own way,
and some endings set none. The two answers were built apart.

Change:
- search-manager.ts: a session gets one outcome when it completes
  (completed, timed_out, stopped, max_results, partial, failed). What
  stopped it first wins; what couldn't be searched is noted by kind. Exit
  code 2 is split: paths ripgrep may not read keep the old permissions
  warning, other errors are trouble. A ripgrep that couldn't search at all
  fails the search, Office matches or not; trouble fails a search that found
  nothing and makes one that found something partial. Context lines are
  marked.
- handlers/search-answers.ts: the one place both answers are built from
  that, every phrase in one table (SEARCH_WORDS).
- search-handlers.ts: start_search and get_more_search_results use it.
- structuredContent (internal, never sent to the client) and telemetry's
  search_session_completed carry outcome in place of the three flags
  (telemetry keeps wasIncomplete, now: some files couldn't be searched).

Tests: test-search-outcome.js passes but for the inputs and runtime cases
(the next commits); the tests that pinned the old answers pass.

…results keeps it (#768)

What the AI saw: get_more_search_results and list_searches reported a
finished search's runtime growing on every read, long after it ended; and a
finished session read only from its end (a negative offset) was dropped by
the cleanup as if nobody read it.

Root cause: the runtime was always now minus the start; only reads with a
positive offset updated lastReadTime.

Change: a session notes when it completed, and its runtime stops there;
every read updates lastReadTime, a tail read too.

Tests: test-search-outcome.js passes but for the inputs case (next commit).

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
What the AI saw: get_more_search_results took length -1 (every result but
the last, then "More results available"), length 0 ("Showing results
0--1", "No results in this range.") and offset 0.5 ("Showing results
0.5-0.5", next offset 1.5); start_search took maxResults 1.5 (it stopped at
2 matches), contextLines 1.5 (ripgrep's "error parsing flag -C") and
timeout_ms -5 (the search timed out at once, nothing found).

Root cause: the schemas took any number.

Change: offset, length, maxResults, contextLines and timeout_ms must be
whole numbers; length at least 1, the others but offset at least 0 (0 keeps
its meaning: no limit, no context). Anything else is rejected with what is
expected ("length must be a whole number of at least 1"); the tools' input
schemas say integer and the minimum.

Tests: test-search-outcome.js passes, every case.

…cess holds as held (#768)

What the repro reported: test-search-child-config-lock.js failed now and
then on macOS with "Lock file is already being held" in
test-search-without-ripgrep.js, before measuring anything: 2 of 20 runs at
1f52820 and 0 of 20 at 1cf3335, alternated in one session.

Root cause: the preload takes the config lock with lockSync(), no retry,
when the test starts a Node.js child. The test's own process can hold that
lock then: the client-id write the first telemetry capture starts, which
nothing awaits. Traced at 1f52820 and d4a3c7d alike, a run takes the
same 4 locks (the first config write, the test's setValue, that client-id
write, the test's restore), and the child starts about 170 ms after the
client-id write; when that write is slow, it is still in flight.
That held lock is the state the preload sets up.

Change: an ELOCKED from lockSync() counts as the lock held. The test's home
is its own and its child hasn't started, so the holder is this process's
own write; the preload says so, with its usual prefix (the repro's "lock held
when its child started" stays true), and leaves the release to that write.

Tests: with every config lock held 300 ms longer (a slow write), the repro
failed 5 of 5 at old and new alike; with this change it passes 5 of 5.
