Summary

  • replace the monolithic application object with explicit domain, application, infrastructure, search, and GPUI UI layers
  • introduce namespace-safe PackageId, typed operations/state/errors, structured process/log events, cancellation, and hardened credential boundaries
  • preserve direct installed-state scanning, Homebrew-authoritative mutations, separate formula/cask batches, virtualization, and low-allocation search
  • embed IBM Plex Mono for application content
  • add documented universal .pkg/.dmg packaging lanes and a CI package smoke test

Security

  • bearer tokens no longer enter process argv, environment variables, temporary files, logs, or debug output
  • Keychain access uses Security.framework rather than /usr/bin/security
  • askpass remains fail-closed and has a documented threat model
  • release packaging requires externally provisioned Developer ID Application and Installer identities plus notarization credentials

Verification

  • cargo fmt --all -- --check
  • cargo clippy --workspace --all-targets --all-features -- -D warnings
  • cargo test --workspace (34 library + 2 icon + 2 askpass tests)
  • cargo test --test homebrew_version_conformance -- --ignored
  • release builds for aarch64-apple-darwin and x86_64-apple-darwin
  • cargo deny check --warn unmaintained
  • shellcheck tools/bundle.sh
  • source secret scan with gitleaks
  • universal ad-hoc app/DMG/PKG build, payload and architecture checks, and code-signature verification

Distribution boundary

The checked-in release path supports signing and notarization, but this machine has no Kettle Developer ID Application/Installer identities or notary profile. Any attached preview artifacts are therefore explicitly unsigned/ad-hoc and not a public notarized release.

📝 Walkthrough

Purpose

This change replaces the monolithic Kettle application with layered domain, application, infrastructure, search, and GPUI UI components. It adds controlled Homebrew operations, cancellation, structured events, namespace-safe package identity, and stricter credential handling for a macOS production client.

Material changes

  • Added domain types for PackageId, formula/cask namespaces, versions, update state, and typed BrewAction.
  • Added PackageStore, application state, selection handling, bounded logs, and operation cancellation.
  • Added Homebrew infrastructure for:
    • Direct installed-state filesystem scanning.
    • Cached catalog loading with race detection and API fallback.
    • Separate formula and cask command plans.
    • Structured stdout/stderr process events.
    • Child-process cancellation and exit-status validation.
  • Added GitHub OAuth device flow with:
    • read:user scope.
    • Redacted AccessToken and device-code debug output.
    • macOS Keychain storage through Security.framework.
  • Hardened kettle-askpass validation:
    • Same-user ownership checks.
    • Permission checks.
    • Strict op:// reference validation.
    • Fixed trusted op locations.
    • Fail-closed behavior with no secret output on error.
  • Added low-allocation fuzzy search and a Criterion benchmark.
  • Added IBM Plex Mono with license and provenance documentation.
  • Added universal .pkg and .dmg packaging modes:
    • dev
    • adhoc
    • release
  • Added CI quality gates for formatting, Clippy, tests, dependency policy, release builds, and package smoke tests.
  • Pinned Rust 1.88 and edition 2024.
  • Added cargo-deny policy restricting registries, licenses, wildcard dependencies, and git sources.

Execution flow

  1. The UI initializes SystemHomebrew, GitHub OAuth transport, and MacKeychain.
  2. The application controller starts a refresh generation.
  3. The backend scans installed formulae and casks directly from Homebrew directories.
  4. The catalog provider loads the local cache, or uses the API fallback when required.
  5. The backend queries outdated packages through Homebrew.
  6. PackageStore reconciles the package sources by namespace-safe PackageId.
  7. SearchIndex ranks filtered candidates without rebuilding search buffers per query.
  8. User actions create typed mutations.
  9. plan_commands separates formula and cask targets.
  10. The process runner executes Homebrew with controlled environment variables and streams structured output.
  11. Cancellation kills the child process and reports an infrastructure error.
  12. OAuth tokens remain in Keychain-backed and zeroizing types.
  13. Release packaging builds, signs, notarizes, and staples artifacts only when the required identities and notary profile exist.

Risk assessment

Category Rating Assessment
Correctness Medium Package reconciliation, version ordering, process status, OAuth polling, and selection behavior have focused tests. Full production behavior still depends on Homebrew and macOS integration.
Memory safety and undefined behavior Low The crate forbids unsafe Rust. No sanitizer or runtime memory-validation evidence is provided.
Concurrency and synchronization Medium Process streams use separate reader threads. Refresh generations and cancellation tokens prevent stale updates. Thread shutdown and UI task interaction require integration validation.
Security and credential handling Medium Tokens avoid arguments, environment variables, temporary files, logs, and debug output. Keychain and askpass boundaries are hardened. Residual risk remains in OAuth, Keychain, sudo, and 1Password integrations.
Performance and resource usage Medium Search uses shared strings and pre-folded buffers. Benchmarks and performance probes exist. Catalog loading, process buffering, and UI log retention still require device-level measurements.
Reliability and recovery Medium Catalog retries, fallback behavior, cancellation, bounded logs, and explicit error types improve recovery. Network, Keychain, Homebrew, and notarization failures remain external dependencies.
Backward compatibility High The architecture, public module layout, manifests, packaging flow, and application entry point changed substantially. Existing integrations with deleted brew.rs and rank.rs APIs require migration.
Deployment and rollback Medium Dev, ad-hoc, and signed release modes support controlled deployment. The current machine cannot produce Developer ID or notarized releases, and rollback procedures are not described in detail.

Validation

Present evidence includes:

  • Unit tests for domain types, version ordering, selection, state, logs, OAuth helpers, Keychain fakes, process execution, askpass validation, and icon generation.
  • Property tests for version-ordering antisymmetry and transitivity.
  • Homebrew version-conformance tests that skip when Homebrew is unavailable.
  • Criterion search benchmarks.
  • Performance probe and documented baseline measurements.
  • CI configuration for rustfmt, Clippy, workspace tests, cargo-deny, dual-architecture release builds, and package smoke tests.
  • Documented checks for dependency policy, shell linting, secret scanning, and universal packaging.
  • Font validity smoke testing.
  • Release signing and notarization support.

Missing or unavailable evidence includes:

  • Actual CI result output.
  • Sanitizer, Miri, or equivalent runtime memory checks.
  • Hardware or production-device validation.
  • Successful Developer ID signing, notarization, and stapling.
  • Public notarized release artifacts.
  • Failure-injection results for Homebrew replacement races, network loss, Keychain denial, process termination, and shutdown during active operations.

Operational impact

  • Requires macOS 14-era targets and Rust 1.88.
  • Requires Homebrew for package discovery and mutation.
  • Requires network access for GitHub OAuth and catalog API fallback.
  • Requires Keychain access for persistent OAuth tokens.
  • Optional privilege integration requires a validated kettle-askpass helper and 1Password CLI at /opt/homebrew/bin/op or /usr/local/bin/op.
  • Release packaging requires:
    • KETTLE_CODESIGN_IDENTITY
    • KETTLE_INSTALLER_IDENTITY
    • KETTLE_NOTARY_PROFILE
  • KETTLE_BUNDLE_ID can override the bundle identifier.
  • Packaging writes application, .pkg, and .dmg artifacts. Release mode signs and notarizes them.
  • No database, schema, IAM, or hardware migration is required.
  • Existing installed application state remains filesystem- and Keychain-based.
  • Rollback can use an earlier application bundle, but existing tokens and Homebrew state are not reverted.
  • Unsigned or ad-hoc artifacts must not be treated as public production releases.

Walkthrough

Kettle is reorganized into a Rust library with domain models, Homebrew and GitHub infrastructure, application state, GPUI views, search, packaging tools, documentation, and macOS quality gates. Authentication, process execution, selection, cancellation, and release packaging receive explicit implementations.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to f5afa

This PR is not merge-ready: privileged package operations may execute replaced helper or command files, cancellation may leave package changes running after the UI reports completion, and CI build inputs can change through a mutable dependency. Failed sign-out can also retain credentials and an empty-content selection path can crash the application; these issues need fixes or explicit security and ownership acceptance before merge.

P2 Badge Filter pinned packages out of Upgrade All

When the outdated list contains a pinned formula, the Cmd-U handler passes it directly to mutate, bypassing the !package.is_pinned() filter used by selected_targets(). The toolbar handler repeats the same logic, so Upgrade All can attempt a package that the primary upgrade path deliberately excludes, causing the batch to fail or report the pinned package among the upgraded targets even though it remains pinned.

P2 Badge Continue with the independent cask plan after formula failure

For a mixed formula-and-cask operation, plan_commands always produces the formula plan first, and this break prevents every cask target from being attempted if that formula invocation fails. These plans are independent namespace-specific commands, so one failure should be accumulated and reported while the remaining plan still runs; otherwise a single formula error silently skips all selected casks.

minimal, and validate.

Inline comments:
In @.github/workflows/rust.yml:
- Line 25: Update the actions/checkout step in the workflow to reference a
full-length commit SHA instead of the mutable v4 tag, preserving the checkout
action’s current major-version behavior.
- Line 25: Update the actions/checkout@v4 step in the workflow to set
persist-credentials to false, keeping the existing checkout behavior unchanged.
- Line 34: Update every Cargo command in the Rust CI workflow—cargo clippy,
cargo test, and both release build commands—to include --locked, ensuring all CI
jobs use the committed Cargo.lock without modifying dependency resolution.

In `@src/application/state.rs`:
- Line 99: Update the refresh flow around SearchIndex::rebuild so a successful
refresh rebuilds the search index only once, after all update callbacks have
populated the package map; remove or defer intermediate catalog, outdated, and
final rebuild calls while preserving filtered reads against the fully refreshed
index.

In `@src/domain/version.rs`:
- Line 35: Update Version::cmp to retain version_cmp ordering while applying a
raw-value comparison as a tie-break whenever normalized versions compare equal,
keeping the result consistent with Version’s byte-exact Eq. Add regression
coverage covering both “1.0” and “1.00” and verify newest_child chooses
deterministically.

In `@src/infrastructure/homebrew/installed.rs`:
- Line 22: Update discover to retrieve and propagate entry metadata errors
before checking whether the path is a directory, rather than using
entry.path().is_dir() directly. Preserve the hidden-name filtering and only skip
entries confirmed not to be directories; map metadata failures through
InfrastructureError::filesystem.

In `@src/infrastructure/homebrew/process.rs`:
- Line 71: Update the process-launch and cancellation flow around Child::kill to
create a dedicated Unix process group and terminate the entire group when
cancellation occurs, ensuring descendant processes cannot keep inherited stdout
or stderr pipes open. Replace or extend the existing /bin/sleep cancellation
test with a bounded test that includes a descendant holding a pipe open and
verifies run returns InfrastructureError::Cancelled.

In `@src/infrastructure/privilege/mod.rs`:
- Line 36: Update validated_askpass_helper and the SystemHomebrew::command
handoff to validate the askpass executable’s parent directory type, ownership,
and permissions, then pass the validated executable through a
non-path-re-resolving handoff so brew cannot resolve an attacker-controlled
replacement.

In `@src/main.rs`:
- Line 2: Update kettle::ui::run to propagate startup failures from
detect_prefix, SystemHomebrew::new, and GitHubTransport::new instead of only
printing them, and change main to return or otherwise map that error so the
process exits with a nonzero status while preserving normal successful startup
behavior.

In `@src/search/score.rs`:
- Line 36: Update the query-length handling in SearchIndex::rank so matching
always uses the complete needle rather than needle.len().min(64); if the 64-byte
limit must remain, reject queries longer than 64 bytes before scoring and ensure
they cannot produce matches.

In `@src/ui/app.rs`:
- Around line 530-532: Handle the None result from controller.begin_mutation in
the mutation action path by providing feedback for rejected mutations, or
disable the corresponding controls while an operation is active or targets are
empty. Ensure cmd-u, enter, and button-triggered actions do not fail silently,
while preserving the existing successful mutation flow.
- Around line 614-621: Update the log-flusher loop around the entity update call
so it exits immediately when this.update returns Err, rather than discarding the
result with .ok(). Preserve the existing finished-and-empty pending condition
and continue normal flushing when updates succeed.
- Around line 361-371: Guard the authentication-state assignments in
restore_session so the callback applies SignedIn or Failed only when
this.controller.state.auth is still SignedOut. If sign_in has already moved the
state to RequestingDeviceCode or another non-signed-out state, leave it
unchanged and avoid notifying because no state changed.
- Around line 567-568: Update the mutation flow around AppController::mutate and
HomebrewBackend::execute so cancellation is user-controllable by connecting the
mutation cancel token to an available UI cancel action; otherwise remove the
unused cancellation token and cancellation polling path, including the
suppressed Cancelled error handling. Preserve normal mutation execution and
error reporting.
- Around line 420-422: Update the OAuth browser-launch flow around
authorization.verification_uri to parse and accept only HTTPS URLs hosted on
github.com before invoking /usr/bin/open; reject invalid values safely. Handle
spawn() errors by logging them, and include verification_uri in the
awaiting-approval panel so users retain a manual fallback when launch fails.
- Around line 514-516: Update the sign-out flow around AuthState::SignedOut and
keychain.delete so deletion failures are observed, surfaced, and prevent
sign-out from being reported complete; ensure restore_session cannot reload a
retained token after failure. Also document that local keychain deletion does
not revoke the GitHub token, or add the required revocation step.
- Line 147: Update the enter key binding in the SearchInput context to bind it
locally, preventing resolution from reaching the parent Kettle context and
triggering Primary; preserve cmd-a’s existing SelectAll behavior.

In `@src/ui/text_input.rs`:
- Around line 238-249: Update index_for_position to return 0 when content is
empty and clamp line.closest_index_for_x to a valid UTF-8 character boundary
within content before mouse_down stores it in selected. Preserve the existing
bounds-based behavior while preventing copy and cut from slicing beyond content.

In `@src/ui/views.rs`:
- Around line 391-395: Update the Help action’s /usr/bin/open handling to retain
the spawned Child and reap it by waiting for completion, using suitable error
handling so spawn or wait failures do not disrupt the UI action.
- Line 315: Add a user-facing Display label implementation for the RefreshStage
enum in the state definitions, then update the OperationState::Refreshing branch
in the status-bar formatting to use the Display representation instead of the
Debug formatter.

In `@tests/homebrew_version_conformance.rs`:
- Around line 42-51: Validate that the parsed authoritative comparison count
matches the number of comparison pairs before any indexing, and report a clear
conformance failure for missing or extra lines. Update the test flow around
authoritative and the pair collection, preserving the existing comparison
mapping and indexed assertions only after cardinality is confirmed.

In `@tools/askpass/src/main.rs`:
- Line 98: Update the executable validation flow around executable_is_safe to
require the canonical executable be owned by the invoking UID or root, and
reject any canonical parent directory component writable or replaceable by an
untrusted account. Preserve the existing file-type and mode checks, applying all
ownership and parent-component checks before returning canonical.

172-172: 📐 Maintainability & Code Quality

Arc::<[PackageId]>::default() was stabilized in Rust 1.80.0. The pinned Rust toolchain is 1.88.0, so the implementation is available.

src/lib.rs (1)

1-7: LGTM! forbid(unsafe_code) at the crate root is the right kind of load-bearing single line.

src/ui/app.rs (3)

671-680: LGTM! The poison-tolerant unwrap_or_else(|poison| poison.into_inner()) on both mutex paths is correct, and the font test asserting the sfnt magic bytes is a genuinely useful invariant instead of a length check alone.

Also applies to: 727-736


164-203: 🎯 Functional Correctness

No change required. src/ui/views.rs registers handlers for About, Help, Minimize, and Zoom on the rendered root element.


701-701: 🔒 Security & Privacy

Establish a token-safe error boundary before rendering.

present_error exposes server-supplied error text and delegates NetworkTransport to reqwest::Error. Map failures to fixed safe messages or redact sensitive values before push_log.

src/ui/mod.rs (1)

1-5: LGTM! Keeping the submodules private and exporting only run is a tight boundary.

Consolidate SearchIndex::rebuild per refresh.

A successful refresh rebuilds the index four times. Each rebuild clears the index and refolds every package name and description. The catalog, outdated, and final rebuilds rescan the accumulated package map from this.update(...) callbacks. Rebuild once after the refresh, or mark the index dirty and rebuild before filtered reads it.

Do not put a Debug enum into the status bar.

format!("Refreshing: {stage:?}") prints the Rust variant identifier. The user reads text such as InstalledFormulae instead of a sentence. Add a display label on RefreshStage in src/application/state.rs and use it here.

♻️ Proposed fix: render a human label
-            OperationState::Refreshing(stage) => format!("Refreshing: {stage:?}").into(),
+            OperationState::Refreshing(stage) => format!("Refreshing: {}", stage.label()).into(),

Addressed the verified review findings in 449ed76:

  • cancellation now owns and kills a Unix process group, including descendants holding pipes, while tolerating an already-exited group
  • formula and cask plans remain independent after a namespace-specific failure
  • Upgrade All excludes pinned packages
  • UTF-16/UTF-8 and empty-placeholder hit testing clamp safely
  • version ordering is consistent with exact equality
  • OAuth browser URLs are restricted to HTTPS on github.com, browser helpers are reaped, restore/sign-out races are guarded, and Keychain deletion failures are surfaced
  • mutations have user-visible rejection feedback and Command-. / Cancel cancellation
  • askpass and op executable ownership, location, and parent permissions are checked
  • startup failures return a nonzero status
  • CI pins checkout, drops persisted credentials, and uses Cargo.lock

The search-index rebuild suggestion was not applied blindly: staged refresh previews must remain searchable while Homebrew work continues, and rebuilds happen during refresh rather than on keystrokes. The measured search path remains within the documented interaction budget; changing preview semantics without a measured bottleneck would trade correctness for speculative optimization.

Post-fix verification: Rust 1.88 fmt, Clippy -D warnings, 42 library tests + tool tests, live Homebrew conformance, both release architectures, cargo-deny, shellcheck, gitleaks, universal app/DMG/PKG packaging, package payload checks, and code-signature verification. The latest GitHub Actions quality job is green.

Findings were addressed or explicitly dispositioned in 449ed76; the replacement CI quality gate is green and the follow-up CodeRabbit check was rate-limited.
