File explorer: add sort options (name / date created / date modified)

[namil-k]

The right-sidebar file explorer always lists folders first, then names case-insensitively, so the newest agent output (screenshots, exports, reports) has to be hunted for by name. The explorer header now has a sort button: name, date created, or date modified, ascending or descending. Date sorts mix files and folders by timestamp; name keeps the folders-first order. The choice persists in UserDefaults and can be managed from cmux.json:

"fileExplorer": {
  "sortBy": "dateModified",   // name | dateCreated | dateModified
  "sortOrder": "descending"   // ascending | descending
}

Local listings read creationDateKey / contentModificationDateKey. SSH listings run a POSIX /bin/sh script with one batched stat (find -exec … +, ARG_MAX-safe) and cache the timestamps; entries without a usable date sort last. A host without base64, find, or a GNU/BSD stat makes the script exit with status 3, and the transport then falls back to a plain ls -1p listing (entries without dates), so those hosts keep listing directories as before. Unreadable directories still exit 1 and unreachable hosts still fail on the first attempt, so neither triggers a retry.

This rebases #6986 onto current main (10k commits later) with the same feature and tests. Beyond conflict resolution:

• Settings parsing moved into KeyboardShortcutSettingsFileStore+SectionParsers and the key registry into CmuxSettingsFileStore+SupportedPaths, following the split main made in the meantime.
• The sort-settings change notification is batched like the sibling *DidChange flags, so changing both keys in one reload posts once.
• The header sort icon uses RenderableSystemSymbol.configuredAppKitImage instead of NSImage(systemSymbolName:).withSymbolConfiguration, matching how main now renders explorer symbols.
• CmuxConfigSchema.generated.swift is regenerated. Without it scripts/generate-cmux-config-schema.py --check fails and cmux config validate rejects the new keys as unknown.
• The configuration docs example lists the new keys.

Rebased again on 2026-09-25 onto main at 3bd994a48b, after the Cloud Files work reshaped the explorer:

• New nodes carry both the sort timestamps and the store's resourceContextID, so sorting composes with the fence that rejects nodes from a replaced provider. Re-sorting only reorders loaded nodes and never creates new ones.
• The header keeps both controls: the sort button sits before the Cloud-only retry button, and moves to the trailing edge when retry is hidden.
• LocalFileExplorerProvider reads the directory and each entry's date resource values in a @concurrent nonisolated helper (the repo's #if compiler(>=6.2) / @Sendable split), so a large folder does not block the main actor.
• The German "Name" string is recorded in scripts/localization-allowed-omissions.json as an intentional identity translation for the new localization parity check.

Rebased again on 2026-09-29 onto main at 5871af150b:

• A sort change bumps sortRevision, which now goes through the same deferred reload as content changes, so it waits while the explorer's context menu is open (Hold Files tree reloads while its context menu is open #14451).
• The ls fallback passes the path through remoteShellPathWord, like the pre-sort listing does since Fix remote Files sidebar for names that change under NFD #14978. Before this, a host that took the fallback got the precomposed path literally, and Process decomposed it to NFD (Remote (cmux ssh) Files sidebar cannot open files whose names change under NFD (Korean, accented Latin, Japanese dakuten, …) #14891). The dated listing was already safe because the whole script travels base64-encoded.

Fixes #5737. Supersedes #6986.

Testing

Ran on macOS 27.0 / Xcode 27.0 (swift-driver 1.168.6), Apple Silicon.

On the current head (deb91a638b):

• python3 scripts/verify-local.py: 9/9 checks pass.
• ./scripts/test-unit.sh test with -only-testing for FileExplorerStoreTests, FileSearchControllerTests, ProcessSSHFileExplorerListingTests, FileExplorerDoubleClickActionTests and FileExplorerSortSettingsTests: 74 tests in 5 suites passed.
• testSSHListingCommandsKeepNFCPathsOutOfProcessArguments fails on ca9bbbf8f9 (8 issues, all legacyIsASCII) and passes on deb91a638b.
• No tagged app build or live check on this head.

On bea7451d1e, before the third rebase:

• python3 scripts/verify-local.py --swift-changed upstream/main: 11/11 checks pass (Swift syntax, xcstrings, localization parity, project normalization, config schema, test wiring, package groups, feature flags).
• ./scripts/reload.sh --tag sort-options: app builds.
• ./scripts/test-unit.sh test with -only-testing for the four suites below: 53 tests in 4 suites passed. Each of the 26 tests this change adds was matched by name in the log.

On 73519f81f4, before the second rebase:

• ./scripts/check-pbxproj.sh, ./scripts/lint-pbxproj-test-wiring.sh (1046 test files), git diff --check, python3 scripts/generate-cmux-config-schema.py --check: pass.
• python3 -m json.tool on web/data/cmux.schema.json, Resources/Localizable.xcstrings, and all 20 web/messages/*.json: valid.
• xcodebuild -scheme cmux-unit build-for-testing: compiles. Then test-without-building for FileExplorerStoreTests, FileExplorerDoubleClickActionTests, FileExplorerSortSettingsTests, ProcessSSHFileExplorerListingTests: 53 tests, 53 passed, including the 26 this change adds (2 sort-order tests, 7 sort-settings and cmux.json parsing tests, 17 remote-listing tests that execute the listing script and the ls fallback through local /bin/sh and parse their output, including exit status 3 with base64 or stat removed from PATH and exit status 1 for a missing directory).
• swift build --package-path Packages/macOS/CmuxFoundation: compiles the regenerated schema. The package's test target does not compile on Xcode 27 (SSHPTYReplayOutputFilterTests.swift, type-check timeout; unrelated and present on main).
• CMUX_DEV_BACKEND_MODE=local ./scripts/reload.sh --tag sort-options: app builds with 0 errors and no new warnings in touched files.
• Live: the tagged app shows the sort button with tooltip and menu; date-modified descending reorders the tree with newest first across files and folders; the choice survives relaunch; saving the keys in cmux.json applies them immediately through the existing settings-file watcher (no manual reload), overriding the menu selection.
• cmux config validate --path from the built app accepts {"fileExplorer": {"sortBy": "dateModified", "sortOrder": "descending"}} and rejects "sortBy": "bogus" with must be one of "name", "dateCreated", "dateModified".

Not verified: SSH sorting and the ls fallback against a real remote host (both covered only by the local /bin/sh execution tests), Intel / Xcode 26 builds, and the sort and retry buttons together in a live Cloud workspace header.

Note for anyone building on macOS 27: the Build Diff Sidecar phase fails there because dyld rejects stripped proc-macro dylibs (mis-aligned LINKEDIT string pool), which rustc reports as can't find crate for tokio_macros. CARGO_PROFILE_RELEASE_BUILD_OVERRIDE_STRIP=none works around it; I'll file it separately since it is independent of this change.

Note

Medium Risk
Medium risk from the SSH remote listing rewrite (shell scripts, fallbacks, and error-status semantics) plus UI reload behavior when sort changes during context menus.

Overview
Adds configurable sorting to the right-sidebar file explorer: sort by name, date created, or date modified, with ascending/descending order. Choices persist in UserDefaults, sync across open explorers via a change notification, and can be set in cmux.json (fileExplorer.sortBy / fileExplorer.sortOrder).

The explorer header gains a sort control (menu + tooltip) wired to FileExplorerStore, which applies FileExplorerNodeSorter when loading and when options change (sortRevision triggers outline reload, including the context-menu deferral path). Name sort keeps folders-first; date sorts interleave types and put entries without timestamps last.

Local listings now collect creation/modification dates off the main actor. SSH listings are reworked to run a POSIX sh script (base64 bootstrap) that batches stat for timestamps, with exit 3 → ls -1p fallback (no dates) and preserved error handling for unreadable paths; NFC path safety applies to both dated and legacy commands.

Schema, settings template/parsers, docs, and localization strings are updated; tests cover sort logic, settings parsing, and remote listing script behavior.

Suggested reviewers: austinywang

Merge Risk: 🔵 Low · up to bea74

Sorting may briefly delay the explorer after many directories have been loaded. The change is otherwise mergeable with awareness of that performance risk.

Security Architecture Review

Security architecture risk: 🔵 Low · up to bea74

The new sorting behavior uses the existing file-explorer and SSH connection paths. The review found no introduced security concern, but remote-host behavior has not been verified across all supported environments.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The independently reachable scope remains the user's existing file-explorer SSH connection. The changed listing commands run on that selected remote host; no new credential or service boundary was identified.

Trust Boundaries and Controls

• observed — Remote output is parsed after command completion, and only status 3 permits a second listing command. Cancellation, access and other command failures are not treated as unsupported-tool success.

Resilience and Maintainability Implications

• observed — A failed explicit listing exposes an error and clears loading state, preserving the ability to retry; the pre-existing untracked silent-prefetch path remains outside explicit-load cancellation ownership.

Full details: Docstring Coverage

Explanation

Docstring coverage is 18.48% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 92 functions across 15 files. (24 skipped: 24 unsupported.)

Full details: Cmux Swift Actor Isolation

Explanation

The PR adds pure Swift 6 value models without an explicit isolation boundary. FileExplorerSortKey, FileExplorerSortOrder, and FileExplorerSortOptions are new Sendable models, but their declarations are not nonisolated. FileExplorerSortSettings is also a new unannotated settings value type used by the non-UI CmuxSettingsFileStore. The PR additionally moves local directory construction into LocalFileExplorerProvider.readDirectoryEntries, an explicitly nonisolated/@concurrent function, while constructing the unannotated FileExplorerEntry. FileExplorerStore and the outline coordinator remain explicitly @MainActor, so those UI accesses are allowed. The failure is limited to the new model and background-boundary declarations.

Resolution

Make the new pure sort models explicitly nonisolated, or use an equivalent Swift-version-compatible isolation arrangement that keeps their raw-value parsing, equality, and configuration use off the main actor. Make FileExplorerEntry explicitly nonisolated because the new local listing worker constructs and returns it from a nonisolated concurrent function. Give FileExplorerSortSettings and its static keys/notification operations an explicit nonisolated boundary, or add an explicit MainActor hop at every non-UI settings-parser call. Keep FileExplorerStore and AppKit/UI coordinator code on @MainActor; do not access those objects from the listing worker.

Full details: Cmux Algorithmic Complexity

Explanation

The PR adds an unbenchmarked comparison sort for scalable file collections. Sources/FileExplorerNodeSorter.swift:11-15 calls nodes.sorted, which is approximately O(k log k) for a sibling collection of size k. Sources/FileExplorerStore.swift:1428-1433 applies that sort to every loaded directory when the sort setting changes, and Sources/FileExplorerStore.swift:1337-1348 applies it during each directory load. A directory with about 1,000 files therefore takes a non-linear sort path. The PR contains functional tests but no benchmark or profiling measurement for this workload.

Resolution

Add a benchmark or profiling measurement for sorting and re-sorting about 1,000 file entries, and document that the measured cost meets the UI budget. If it does not, cache per-directory orderings keyed by FileExplorerSortOptions or maintain an indexed ordering so a sort change does not re-sort every loaded collection.

Full details: Cmux Swift `@Concurrent`

Explanation

The PR adds a UI-triggered remote listing path that lacks an explicit concurrency boundary. FileExplorerStore.loadChildren is @MainActor and awaits provider.listDirectory (head Sources/FileExplorerStore.swift:1319-1335). The changed SSH path reaches ProcessSSHFileExplorerTransport.runSSHListCommand (head :446-452, :705-728), which now performs metadata-output parsing and fallback handling after the network await. That helper has no @concurrent annotation. runSSHCommandResult dispatches the blocking process to DispatchQueue.global, but it does not move the subsequent parseRemoteListing or parseLegacyListing work off the caller actor. The local equivalent correctly uses @concurrent on readDirectoryEntries (head :298-304).

Resolution

Add a Swift 6.2-guarded @concurrent boundary to the changed SSH listing operation, preferably at ProcessSSHFileExplorerTransport.listDirectory and/or runSSHListCommand, so remote command setup, output parsing, and fallback handling do not inherit @MainActor. Keep the existing DispatchQueue.global hop for the blocking process and verify that the protocol requirement and older-compiler fallback remain compatible.

Full details: Cmux Swift Package Boundaries

Explanation

The PR adds independently testable file-explorer domain logic directly under the app target's root Sources/. FileExplorerSortKey, FileExplorerSortOrder, FileExplorerSortOptions, and FileExplorerSortSettings import only Foundation. FileExplorerNodeSorter contains pure ordering rules, and the new tests instantiate the sorter and UserDefaults-backed settings without UI. The Xcode project registers these files in the app target, while no SwiftPM target is added. The AppKit header and store lifecycle code may remain in the app, but the sort model, sorting rules, and settings persistence cross the package-boundary signals in the rule.

Resolution

Create a small Packages/macOS/CmuxFileExplorerCore SwiftPM package target. Expose FileExplorerSortOptions as the first public value API, with public FileExplorerSortKey and FileExplorerSortOrder; move the sorting implementation and injected settings persistence into that target. Make the sorter operate on a package-owned date-bearing entry value, or move the non-UI FileExplorerEntry model with it. Move the corresponding pure tests to the package test target. Keep FileExplorerHeaderView, AppKit menu wiring, FileExplorerStore orchestration, and process/UI composition in Sources/, and add the package product as an app dependency.

@greptile-apps review

[namil-k]

Rebased onto current main. Conflicts were with the Cloud Files work: sorting now composes with the resourceContextID fence, and the header keeps both the sort control and the Cloud retry button. The embedded schema was regenerated with scripts/generate-cmux-config-schema.py.

Pre-merge checks:

• @Concurrent: LocalFileExplorerProvider now reads the directory and date resource values in a @concurrent nonisolated helper, using the repo's #if compiler(>=6.2) split.
• Actor isolation: I left FileExplorerSortKey/Order/Options without nonisolated. The app target has no default MainActor isolation (Swift 5 mode, no SWIFT_DEFAULT_ACTOR_ISOLATION), so they are already nonisolated and Sendable. Type-level nonisolated would also break the Xcode 16.2 / Swift 6.0 path that AGENTS.md protects (SE-0449).
• Package boundaries: extracting the sort model needs a small protocol seam because the sorter works on the app's FileExplorerNode, following the CmuxCloudBannerCore pattern. It is about 20 files, so I'd like to ask before doing it: would you prefer it in this PR, as a follow-up, or under a broader CmuxFileExplorer package?

In `@Sources/FileExplorerStore.swift`:
- Around line 1428-1435: Update resortLoadedNodes so it eagerly sorts only
rootNodes and children of nodes in expandedPaths, rather than every cached node
in nodesByPath. Track the sort revision for cached children and have
expand(node:) sort existing children when their revision is stale, so collapsed
subtrees use the current sort order when expanded.

After applying the fix, consider running `coderabbit review --agent` for local

Bugbot is paused — on-demand spend limit reached

Bugbot uses usage-based billing for this team and has hit its on-demand spend limit.

A team admin can raise the spend limit in the Cursor dashboard, or wait for the next billing cycle to continue.

Rebased onto current main (5871af150b). Besides the conflicts, the rebase exposed one regression: the ls fallback put non-ASCII paths in the ssh command literally, which undid #14978 on that path. It's fixed in deb91a638b with a regression test in ca9bbbf8f9. The description has the details and the test results for this head.

The workflows for this head are waiting on approval (action_required) because the PR comes from a fork. Could a maintainer approve them?

Thanks @namil-k, the file explorer sort options are useful. This is held for a design call on the sort controls; the main conflict and open bot threads also need resolution before merge :)

Thanks @teamleaderleo! Caught up with main (head 817dfa4, mergeable again; verify-local.py passes and the tagged app builds), and the CodeRabbit threads are resolved.

For the design call: the explorer header gets a sort button (Name / Date Created / Date Modified, ascending or descending, also settable in cmux.json). The default stays Name, ascending, so the tree looks exactly like today until someone changes it. Date sorts mix folders and files like Finder; Name keeps folders first.

Sort button, with Date Modified, ascending applied:

The menu:

Back on Name, ascending (today's order, folders first):
