Follow-up to the push-sweep review: the previous UNSAFE_REGEX used
JS bitwise OR (|) between regex literals, accidentally OR-ing the
RegExp objects instead of combining alternatives into one pattern.
Replace with a single RegExp that catches:
- nested quantifiers (a+)+, [a-z]*+
- class + quantifier
- dot-quantifier followed by dot-quantifier
- lookahead / lookbehind (?=, ?!)
- backrefs \1..\9
- alternation + quantifier
Also add MAX_REGEX_LENGTH=200 hard cap. The denylist is still
defense-in-depth — the length, files-traversed, and per-file-byte caps
are the primary defense.
Address findings from automated security review:
1. Validate rootPath via validatePath/isPathAccessible before recursing,
matching the pattern used by read-file/write-file.
2. Cap query length at 1024 chars to bound regex compilation cost.
3. Reject regexes matching classic ReDoS shapes (nested quantifiers
and similar) before invoking RegExp.
4. Use realpathSync to resolve symlinks and verify containment under
rootPath; drop symlinks that point outside the search root.
5. Cap total files traversed at 10000, in addition to existing
1000-result and 2MB-per-file caps.
Add regression tests for each guard.
CrashReportModal crashed on dumps.map because ipc.crash.read returns
{ ok, data } and the consumer was assigning the wrapper to state. Now
unwraps .data and falls back to [] on error.
ipc.file.search was miswired to ipc.file.pickFile — clicking 'Search'
popped a file picker instead of searching. Add real 'search-in-files'
handler in src/main/files/search-in-files.js with regex support,
case-sensitivity toggle, .git/node_modules/dist skip, 2MB file cap, and
1000-result limit. Wire preload bridge + TS declaration + allowlist.
Also:
- Drop dead ipc.file.open wrapper that was miswired to pickFile
- Rename FileEntry field 'modified' to 'modifiedAt' (number) so the
IPC payload matches the declared type
- Update CrashReportModal tests to use the safeCall envelope shape
The list-directory handler returned { path, entries } while the
renderer typed result.data as FileEntry[]; the file-store had to fall
back to raw.entries via Array.isArray. Extract the entries builder into
src/main/files/list-directory.js so it can be unit-tested, return a
plain array, and skip entries that can't be stat'd (broken symlinks,
permission errors) instead of throwing.
Also tighten jest config so dist/*.snap electron-builder artifacts are
not matched as test suites.
GitOperations.getStatus returns { files: [...] } but the renderer's
ipc.file.gitStatus type declares Array<...> and calls result.data.map().
The mismatch made GitStatusPanel.tsx throw 'n.map is not a function'
on mount, which blanked the entire React tree.
Unwrap result.files in the IPC handler so it returns the array the
renderer expects. Add tests covering the success, empty, and non-git
branches so this regression cannot recur.
