Summary by Sourcery

Improve worker shutdown semantics and test reliability while integrating nextest-based coverage into the build.

New Features:

  • Add configurable test-support feature gating for worker drained hooks to allow use outside unit tests.
  • Introduce a nextest configuration file to control per-test and global timeouts and exclude cucumber binaries from default runs.

Bug Fixes:

  • Correct worker queue metadata detection to ignore send.lock files when checking for emptiness.
  • Fix supervisor restart test by removing unnecessary mutable closures that could interfere with task construction.
  • Adjust listener race-condition test to be async-compatible using tokio.

Enhancements:

  • Refine worker hook notifications to use single-waiter semantics and idle-based signalling, and make shutdown-aware cooldown waits break out of the worker loop.
  • Improve worker request handling tests with realistic GitHub API response shapes, richer diagnostics, and more accurate expectations around queue file cleanup and retries.
  • Update logging and worker API documentation examples to use public crate paths and accurate return semantics.
  • Relax expectations in error-path tests to allow multiple HTTP attempts while still asserting non-commit behaviour.

Build:

  • Switch test and coverage targets to use cargo-nextest for primary execution and llvm-cov integration, add separate cucumber runs, and scope clippy and test invocations to the workspace.
  • Update markdown linting and Mermaid diagram validation commands to use markdownlint-cli2 and a sandbox-free nixie invocation.

Tests:

  • Strengthen daemon worker tests with improved mock server expectations, richer diagnostics on timeouts, and clearer pass/fail messaging.
  • Ensure timeout configuration tests exercise all complexity variants without relying on drop semantics.
  • Adjust workflow tests to embed expected actions directly into YAML fixtures for clearer assertions.

File-Level Changes

Change Details Files
Improve daemon worker lifecycle, hooks, and shutdown semantics, and adapt tests accordingly.
  • WorkerHooks now uses notify_one instead of notify_waiters for enqueued/idle/drained notifications and exposes drained-related code under test or test-support feature gates.
  • WorkerHooks::wait_or_shutdown now returns a bool indicating whether shutdown was signalled, and callers break the worker loop early on shutdown instead of always sleeping.
  • run_worker’s main loop is restructured to prioritize shutdown over receiving new messages, to break on shutdown after cooldowns and error paths, and to use explicit CommentRequest deserialisation typing.
  • Worker tests switch from drained to idle notifications, adjust timeouts, logging, and panic messages, and stop asserting on physical queue data-file deletion due to yaque’s lazy cleanup semantics.
crates/comenqd/src/worker.rs
crates/comenqd/tests/daemon.rs
Strengthen diagnostics and expectations around HTTP interactions and queue state in worker tests.
  • Mock GitHub server responses now return a realistic Comment on success and a GitHub-style error JSON on non-2xx statuses, with request count expectations on the mock.
  • Queue diagnostics output uses Rust’s inline formatting for clarity and adds more robust printing of remaining queue files, including their size and age.
  • Worker success tests now assert on single-server-request semantics only, while error tests only require at-least-once requests and explicitly assert that queue data files remain when processing fails.
crates/comenqd/tests/daemon.rs
Modernize test and coverage tooling and configuration.
  • Makefile test target now runs cargo-nextest for the full workspace plus a separate cucumber test run, with RUSTFLAGS enforcing warnings as errors.
  • Coverage targets are split so that nextest-based runs and cucumber tests are each included in llvm-cov with appropriate flags, including separate LCOV outputs for cucumber.
  • Adds a .config/nextest.toml to configure per-test and global timeouts and exclude the cucumber binary from the default nextest filter.
  • Updates markdown linting and Mermaid validation commands to use markdownlint-cli2 and nixie’s no-sandbox mode.
Makefile
.config/nextest.toml
Fix and simplify documentation examples and test-support helpers.
  • Adjusts doc examples to use the public comenqd::logging and comenqd::daemon paths instead of crate-relative ones, and simplifies example main functions.
  • Listener module examples now reference daemon::listener and a long-running race test is switched to #[tokio::test] async to integrate with async runtime.
  • Test-support workflow tests embed EXPECTED_RUST_BUILDER correctly in YAML snippets without positional formatting placeholders.
  • Supervisor tests simplify closure capturing by removing unnecessary mutability and using direct closures.
crates/comenqd/src/logging.rs
crates/comenqd/src/listener.rs
test-support/src/workflow.rs
crates/comenqd/tests/supervisor.rs
Tighten utility functions and test usage around queue metadata and complexity enum coverage.
  • METADATA_FILE_NAMES now includes send.lock so it’s treated as queue metadata and ignored by drained/emptiness checks.
  • util tests now bind TimeoutConfig::new results to a throwaway variable instead of calling drop explicitly, maintaining usage coverage while simplifying code.

Poem

🔔 Broadcasters fell silent, one notifier now calls,
Timeouts tightened, tests refined in smaller halls.
Logs accept a writer, filters pinned by hand,
A metadata lock arrived to join the band.
Run nextest first — keep the pipelines grand.

89-89: Direct environment mutation is forbidden in tests.

Per coding guidelines, env::set_var is unsafe in Rust 2024 and direct environment mutation in tests is forbidden. Use dependency injection with the mockable crate, or wrap env mutations in shared guards and mutexes placed in a shared test_utils crate.

The unsafe block is correctly applied for Rust 2024, but the approach itself violates the guideline: "Direct environment mutation is FORBIDDEN in tests."

🔎 Suggested approach

Refactor to inject the filter configuration rather than mutating the environment:

-    #[test]
-    fn init_logging() {
-        let buf = Arc::new(Mutex::new(Vec::new()));
-        unsafe { std::env::set_var("RUST_LOG", "info") };
-        init_with_writer(BufMakeWriter { buf: buf.clone() });
+    #[test]
+    fn init_logging() {
+        let buf = Arc::new(Mutex::new(Vec::new()));
+        // Use a test-specific init function that accepts an explicit filter
+        init_with_writer_and_filter(BufMakeWriter { buf: buf.clone() }, "info");

Alternatively, create a test_utils module with proper synchronisation primitives for env access.

Based on coding guidelines.

**/*.rs: Clippy warnings MUST be disallowed.
Fix any warnings emitted during tests in the code itself rather than silencing them.
Where a function is too long, extract meaningfully named helper functions adhering to separation of concerns and CQRS.
Where a function has too many parameters, group related parameters in meaningfully named structs.
Where a function is returning a large error consider using Arc to reduce the amount of data returned.
Write unit and behavioural tests for new functionality. Run both before and after making any change.
Every module must begin with a module level (//! ) comment explaining the module's purpose and utility.
Document public APIs using Rustdoc comments (///) so documentation can be generated with cargo doc.
Prefer immutable data and avoid unnecessary mut bindings.
Handle errors with the Result type instead of panicking where feasible.
Avoid unsafe code unless absolutely necessary and document any usage clearly.
Place function attributes after doc comments.
Do not use return in single-line functions.
Use predicate functions for conditional criteria with more than two branches.
Lints must not be silenced except as a last resort.
Lint rule suppressions must be tightly scoped and include a clear reason.
Prefer expect over allow.
Use rstest fixtures for shared setup.
Replace duplicated tests with #[rstest(...)] parameterised cases.
Prefer mockall for mocks/stubs.
Prefer .expect() over .unwrap().
Use concat!() to combine long string literals rather than escaping newlines with a backslash.
Prefer semantic error enums. Derive std::error::Error (via the thiserror crate) for any condition the caller might inspect, retry, or map to an HTTP status.
Use an opaque error only at the app boundary. Use eyre::Report for human-readable logs; these should not be exposed in public APIs.
Never export the opaque type from a library. Convert to domain enums at API boundaries, and to eyre only in the main main() entrypoint or top-level async task.

Relevant Context for PR #125 Review

Based on the comenq project documentation and code context, I've identified key information relevant to reviewing this pull request on "Coverage test failure":

Project Overview and Test Architecture

The comenq system is a fault-tolerant GitHub comment management service with a sophisticated three-task daemon architecture (listener, queue writer, worker).

Primary PR Changes Addressing Coverage Issues

1. Nextest Integration (.config/nextest.toml)

  • New configuration file introduces nextest as the test runner with specific timeout and filter settings
  • 60-second per-test timeout with 5-second grace period
  • 10-minute global timeout for entire test run
  • Filters out cucumber tests from default run (via binary(cucumber) filter)

This change directly addresses the "Coverage test failure" by introducing nextest to the CI pipeline.

2. Makefile Test Execution Changes

  • Test target now runs cargo nextest followed by a separate cucumber invocation
  • Both use workspace-wide and all-targets/all-features settings
  • Coverage commands updated to use cargo-llvm-cov with nextest integration
  • test-cov-lcov updated for LCOV generation with both general and cucumber-focused coverage steps

Critical Detail: The Makefile now explicitly separates nextest execution from cucumber tests, addressing potential incompatibility between nextest and the BDD test framework.

3. Test Harness Changes (crates/comenqd/src/listener.rs)

  • Changed from #[test] to #[tokio::test] for async test harness compatibility
  • Test function now properly async to support tokio execution

This change ensures async tests work correctly with nextest.

4. Worker Task Modifications (crates/comenqd/src/worker.rs)

  • Replaced notify_waiters() with notify_one() in WorkerHooks (notify_enqueued, notify_idle)
  • wait_or_shutdown() now returns boolean instead of non-returning async function
  • Expanded test-support feature gating with #[cfg(any(test, feature = "test-support"))]

These changes affect test coordination and shutdown signal handling, critical for test reliability.

5. Daemon Test Updates (crates/comenqd/tests/daemon.rs)

  • Replaced idle/drained notification mechanism - changed from "drained" to "idle" terminology
  • Dynamic response bodies based on HTTP status code
  • Verification of exactly one server request (removed strict queue data verification)
  • Changed from is_metadata_file to direct checks

The notification mechanism change is significant - tests now wait for idle notifications instead of drained notifications.

6. Test Support Feature Flag Changes (crates/comenqd/src/util.rs)

  • Expanded METADATA_FILE_NAMES constant from 2 to 3 entries, adding "send.lock"

This affects metadata file recognition during testing.

Coverage Test Failure Root Cause

From the documentation, coverage test failures typically occur due to:

  • Test failures preventing coverage generation from completing
  • Low code coverage falling below thresholds
  • Configuration issues with coverage tools

The PR addresses this by:

  1. Integrating nextest which may handle async tests more reliably
  2. Separating nextest execution from cucumber tests to avoid conflicts
  3. Updating cargo-llvm-cov integration with nextest
  4. Fixing async test harnesses to work properly with nextest

Key Review Considerations

  1. Test Harness Compatibility: The switch from #[test] to #[tokio::test] ensures proper async handling with nextest
  2. Notification Mechanism: The idle vs. drained notification change affects test synchronization - verify this doesn't introduce race conditions
  3. Coverage Tool Integration: Nextest + cargo-llvm-cov integration requires careful sequencing in the Makefile
  4. Cucumber Test Separation: Separating cucumber from nextest execution prevents framework incompatibilities
  5. Signal Handling: The wait_or_shutdown() return type change affects test coordination - ensure proper handling of shutdown signals
⏰ Context from checks skipped due to timeout of 120000ms. You can increase the timeout in your CodeRabbit configuration to a maximum of 15 minutes (900000ms). (1)

🔇 Additional comments (34)
crates/comenqd/src/logging.rs (2)

17-21: LGTM!

Documentation examples correctly updated to reference the public crate path comenqd::logging for external consumers.


31-35: LGTM!

Documentation path reference correctly updated for init_with_writer.

.config/nextest.toml (1)

1-11: LGTM!

Sensible Nextest configuration:

  • Per-test timeout of 60s prevents runaway tests
  • Global timeout of 10m caps CI duration
  • Cucumber exclusion is correct since cucumber tests don't support nextest's --list command

This addresses the coverage test failure by providing better test runner control.

crates/comenqd/tests/util.rs (1)

98-100: LGTM!

Using let _ = ... is more idiomatic than drop(...) for discarding values. The parameterised test correctly exercises all TestComplexity variants.

test-support/src/workflow.rs (2)

86-88: LGTM!

Inlining {EXPECTED_RUST_BUILDER} directly in the format string is cleaner than using a separate format argument.


113-114: LGTM!

Consistent with the pattern in detects_shared_actions.

crates/comenqd/src/listener.rs (2)

31-31: LGTM!

Documentation path correctly updated to reflect the daemon module namespace.


172-173: LGTM!

Converting to #[tokio::test] ensures proper async test harness compatibility with nextest. The test body uses synchronous operations wrapped in a spawned thread, which works correctly in an async context.

Makefile (6)

6-7: LGTM!

Adding --workspace to CLIPPY_FLAGS ensures all crates are linted. The switch to markdownlint-cli2 is appropriate as it supports glob patterns natively.


37-38: LGTM!

Separating nextest and cucumber test runs is the correct approach since cucumber tests don't support nextest's --list command. Both runs apply -D warnings consistently.


42-43: LGTM!

Coverage commands properly integrate nextest via cargo llvm-cov nextest, with cucumber coverage collected separately using --no-clean to preserve instrumentation data.


48-49: LGTM!

LCOV generation correctly produces separate output files for nextest and cucumber coverage, enabling downstream tooling to merge or process them independently.


65-65: LGTM!

The glob pattern "**/*.md" is the idiomatic invocation for markdownlint-cli2.


68-68: LGTM!

The --no-sandbox flag is a valid invocation option for nixie.

crates/comenqd/src/worker.rs (7)

16-21: LGTM!

Expanding cfg guards to #[cfg(any(test, feature = "test-support"))] enables test infrastructure to be used both in unit tests and integration tests via the feature flag.


71-80: LGTM!

Switching from notify_waiters() to notify_one() is appropriate for the single-waiter pattern used in tests. This ensures only one waiter is woken, matching the test harness design.


83-96: LGTM!

The notify_drained_if_empty method correctly uses notify_one() for consistency with the single-waiter notification pattern.


98-134: LGTM!

Changing wait_or_shutdown to return a bool improves clarity:

  • true indicates shutdown was signalled
  • false indicates timeout expired

The biased select ensures shutdown signals take priority, preventing race conditions where a timeout and shutdown arrive simultaneously.


148-164: LGTM!

Documentation correctly updated to reference daemon::WorkerControl and daemon::WorkerHooks.


175-203: LGTM!

The refactored select loop correctly:

  1. Uses biased to prioritise shutdown signals
  2. Handles deserialisation errors gracefully, calling wait_or_shutdown and breaking if shutdown was signalled
  3. Maintains proper notification ordering (enqueued → process → idle)

228-237: LGTM!

The end-of-loop and post-loop shutdown handling correctly uses the boolean return from wait_or_shutdown to determine whether to break. The final notify_drained_if_empty call ensures tests receive the drained notification on clean shutdown.

crates/comenqd/src/util.rs (1)

10-10: LGTM!

Adding "send.lock" to METADATA_FILE_NAMES correctly accounts for all yaque queue metadata files. The queue implementation uses both recv.lock and send.lock for coordination, so this fix ensures is_metadata_file identifies all sentinel files when checking for an empty queue.

crates/comenqd/tests/supervisor.rs (4)

1-1: Module-level documentation present.

The module begins with the required //! doc comment explaining its purpose.


70-70: Panic message formatting improvement approved.

The embedded variable syntax {timeout_duration:?} is cleaner and more idiomatic than the previous Debug-style formatting.


89-89: Immutable bindings are appropriate here.

The listener_maker and worker_maker are passed directly to supervise_until_restarts, so mutable bindings are unnecessary. This aligns with the guideline to prefer immutable data.


150-154: Simplified closure passing approved.

Passing listener_maker and worker_maker directly to the supervisor task is cleaner than wrapping them in additional move || ... closures. The Box<dyn FnMut...> types satisfy the FnMut bounds of supervise_until_restarts.

crates/comenqd/tests/daemon.rs (8)

1-1: Module-level documentation with en-GB spelling approved.

The module begins with the required //! doc comment using correct en-GB-oxendict spelling ("behaviour").


6-10: Import change aligns with public API updates.

The removal of is_metadata_file from imports reflects the broader refactoring where this function is no longer publicly exported from the daemon module.


317-326: Idle notification pattern aligns with worker refactoring.

The change from drained to idle notification is consistent with the broader worker notification mechanism refactoring. The WorkerHooks struct now uses notify_one() instead of notify_waiters(), and tests wait for idle signals to confirm processing completion.


329-344: Updated notification wait logic approved.

The transition to waiting for idle notification rather than drained is correct. The timeout handling and diagnostic output are well-structured for debugging test failures.


365-372: Documentation of yaque behaviour is helpful.

The comment explaining why queue data files are not asserted upon (due to yaque's lazy segment cleanup) provides valuable context for future maintainers and prevents confusion about test expectations.


425-441: Error path assertions are well-structured.

The assertions verify both that:

  1. At least one request was attempted (proving worker processed the job)
  2. Queue retains data files (proving job was not committed due to error)

This correctly validates the requeue-on-error behaviour.


280-306: String formatting improvements approved.

The embedded variable syntax ({queue_files}, {file_num}, etc.) is cleaner and more idiomatic than positional format arguments. The diagnostic output function is well-structured.


295-300: No action needed. The workspace and cemenqd crate both specify edition = "2024" in their Cargo.toml files, so the let-chain syntax is valid and supported.

216-254: Large inline JSON blocks — extract to external fixture files.

This was flagged in a previous review and remains unaddressed. The JSON response bodies exceed 40 lines and violate the coding guideline requiring large inline data blocks to be moved to external files.

🔎 Proposed approach

Create fixture files:

  • tests/fixtures/github_comment_response.json
  • tests/fixtures/github_error_response.json

Then load them:

let response_body: serde_json::Value = if (200..300).contains(&status) {
    serde_json::from_str(include_str!("fixtures/github_comment_response.json"))
        .expect("parse comment fixture")
} else {
    serde_json::from_str(include_str!("fixtures/github_error_response.json"))
        .expect("parse error fixture")
};

As per coding guidelines: "Large blocks of inline data (e.g., test fixtures, constants or templates) must be moved to external files and inlined at compile-time or loaded at run-time."

Summary — additional facts useful for reviewing PR #125

  • Project uses a three-task daemon (listener → queue_writer → worker) with yaque transactional queue; worker enforces a 10s per-request timeout and a configurable cooldown (default 960s). Changes to worker shutdown/notify semantics directly affect this pipeline and retry semantics.

  • Test infra: behavioural tests run via a cucumber harness (tests/cucumber.rs) with eight World types (including WorkerWorld, ListenerWorld). Tests rely on test-support crate utilities: EnvVarGuard for env isolation, wait_for_file with SOCKET_RETRY_COUNT / SOCKET_RETRY_DELAY for async file/socket polling, and wiremock-based HTTP mocks for GitHub. Modifying notification/wait behaviour (notify_one, wait_or_shutdown boolean) will affect these worlds and tests that assert idle/drained signals or use wait_for_file.

  • CI & tooling: CI workflow installs nextest (new step) — PR adds .github/workflows/ci.yml change to install nextest and new .config/nextest.toml controls per-test and global timeouts and excludes cucumber binaries (binary(cucumber)). Makefile now runs cargo nextest and separates cucumber runs; coverage uses cargo-llvm-cov with nextest. Verify CI step and Makefile changes align (installed nextest v0.9.108 in workflow).

  • Test-support best practices: tests avoid mutating global env by using EnvVarGuard and the new TimeoutConfig.with_ci/with_coverage builders — relevant because PR replaces env mutation with explicit flags and adds init_with_writer_and_filter to logging tests to avoid altering RUST_LOG. Ensure new APIs preserve test isolation.

  • File/queue metadata: project treats specific metadata filenames when deciding queue emptiness; PR adds "send.lock" to METADATA_FILE_NAMES — check places relying on is_metadata_file or metadata enumeration (tests were updated to remove public is_metadata_file import).

Relevant sources used:

  • Project architecture, worker/queue/timeouts, and post_comment timeout/cooldown details.
  • Testing framework, test-support utilities (EnvVarGuard, wait_for_file, SOCKET_RETRY_*), BDD Worlds (WorkerWorld, ListenerWorld), and mocking details.
  • CI/workflow and nextest/coverage tooling notes (nextest install step, nextest.toml effect, Makefile -> cargo nextest/llvm-cov).
🔇 Additional comments (17)
crates/comenqd/src/logging.rs (2)

32-36: LGTM!

The documentation example correctly references the public crate path and demonstrates proper usage.


113-114: LGTM!

The test correctly uses the new function to avoid environment mutation, adhering to the coding guidelines. The comment clearly explains the rationale.

.github/workflows/ci.yml (1)

20-23: Installation step is sound. Both nextest 0.9.108 and the action SHA are valid.

The step correctly implements security best practices through SHA pinning of the action and version pinning of the tool. Positioning after Rust setup and before test/coverage steps is appropriate.

crates/comenqd/tests/retry_helper.rs (4)

14-29: LGTM — explicit flag configuration eliminates environment mutation.

The refactor to use .with_ci(false).with_coverage(false) aligns with the coding guidelines forbidding direct environment mutation in tests. This approach ensures test isolation when tests run in parallel.


32-49: Approve new coverage scaling test and CI test refactor.

The new calculate_timeout_scales_with_coverage test provides coverage for the coverage multiplier path. Both tests correctly use explicit flags and verify the expected multiplier arithmetic.


51-77: LGTM — complexity and progressive retry tests updated correctly.

Tests now use explicit configuration flags throughout, ensuring deterministic behaviour regardless of the environment.


79-133: Async retry tests properly isolated.

The retries_after_timeout_then_succeeds and fails_after_all_retries tests correctly use explicit flags, ensuring consistent timeout calculations in paused-time tests.

crates/comenqd/tests/util.rs (3)

25-38: Builder fields and constructor look good.

The Option<bool> fields with doc comments and None defaults in new() provide a clean foundation for the builder pattern.


68-77: Environment fallback logic is correct.

The unwrap_or_else pattern cleanly falls back to environment variable checks when explicit flags are not set. This maintains backward compatibility whilst allowing explicit configuration.


124-126: Prefer let _ = over drop() for unused values — approved.

This is idiomatic Rust for discarding a value without invoking destructor semantics explicitly.

crates/comenqd/tests/daemon.rs (7)

6-10: Import cleanup approved.

Removing is_metadata_file from the import aligns with the broader change where this function is no longer publicly re-exported from the daemon module.


255-260: Mock expectation change approved.

Using .expect(1..) to allow at least one request is appropriate for tests that may involve retries.


280-305: Diagnostic improvements approved.

The updated formatting with interpolated variables improves readability and removes unnecessary intermediate bindings.


317-344: Worker success test uses idle-based signalling — approved.

The change from drained to idle notification aligns with the PR objective of refining worker hook notifications to use idle-based signalling. The diagnostic output and panic messages are clear.


365-371: Helpful comment explaining yaque cleanup semantics.

The comment clarifies why asserting on queue data files is unreliable — yaque cleans up segment files lazily during the next recv() call. This prevents future confusion about test expectations.


425-441: Error test assertion relaxed appropriately.

Asserting !is_empty() instead of exact request count is correct since retries may occur before shutdown. The assertion on queue file retention verifies the job was not committed.


295-300: No action required. Let-chains are fully supported in this codebase. The project specifies edition = "2024", which was released with Rust 1.85.0 (February 20, 2025). Let-chains stabilised in Rust 1.80.0 (August 2024), so the chained if let ... && let ... syntax compiles without issue on this edition and MSRV.

Multiple issues caused worker tests to timeout or fail intermittently:

- Use #[cfg(any(test, feature = "test-support"))] instead of #[cfg(test)]
  for code needed by integration tests (not just unit tests)
- Change Notify::notify_waiters() to notify_one() which buffers a permit
  for later consumption by single consumers
- Make wait_or_shutdown() return bool to indicate whether shutdown was
  signaled, since watch::changed() consumes the notification
- Add send.lock to METADATA_FILE_NAMES for yaque queue detection
- Fix mock server responses to include all fields required by octocrab:
  - 2xx responses: full GitHub Comment JSON with node_id, user fields, etc.

67-68: Restore explicit file arguments or verify nixie default behaviour.

The previous invocation passed an explicit list of Markdown files (excluding target/); the current command runs nixie --no-sandbox with no paths. Verify that nixie's default behaviour matches the previous explicit file selection. If not, restore the file arguments to preserve the original validation scope.

216-254: Extract large inline JSON to external files.

These ~40-line JSON blocks violate the coding guideline requiring large inline data to be moved to external files. Extract to tests/fixtures/github_comment_response.json and tests/fixtures/github_error_response.json, then load with include_str!.

Summary of additional repository facts relevant to reviewing PR #125 (Coverage test failure)

  • Workspace uses a three-task comenqd daemon: run_listener → queue_writer → run_worker; worker uses yaque transactional queue with RecvGuard, 10s per-request timeout, and a configurable cooldown (default 960s). Changes to worker shutdown/notify semantics and METADATA_FILE_NAMES affect core processing & queue-empty detection.

  • Testing infra: BDD cucumber harness runs 8 World types (including WorkerWorld, ListenerWorld). Tests rely on test-support utilities (EnvVarGuard, wait_for_file with SOCKET_RETRY_COUNT/SOCKET_RETRY_DELAY, wiremock mocks). Altered notify/wait behavior, wait_or_shutdown return type, and making drained → idle changes will affect these worlds and tests.

  • test-support crate provides utilities used across tests (temp_config, octocrab_for, EnvVarGuard, wait_for_file). The test suite uses serialisation/EnvVarGuard patterns for safe env changes — PR replacing env mutation with explicit flags (with_ci/with_coverage) and adding init_with_writer_and_filter aligns with these practices.

  • CI/tooling: .github workflow installs nextest (new step) — Makefile and coverage targets were changed to use cargo nextest and cargo-llvm-cov with nextest-aware invocation; .config/nextest.toml added global-timeout 10m, slow-timeout 60s and excludes cucumber binaries (default-filter: not binary(cucumber)). Workflow installs nextest v0.9.108. Verify CI step & Makefile nextest invocations are consistent with that version.

  • Public API surface: logging.rs adds pub fn init_with_writer_and_filter<...>(writer, filter) to avoid environment mutation in tests; worker::wait_or_shutdown signature changed to return bool (shutdown indicator). These are visible API/test-support hooks that require careful review for callers.

  • File/queue metadata: METADATA_FILE_NAMES now includes "send.lock" (was ["version","recv.lock"]), so is_metadata_file behavior and tests that previously used/assumed is_metadata_file were updated (public re-export removed from tests). Check any code/tests relying on prior metadata name set.

  • Worker notification changes: Notify::notify_waiters() → notify_one() and drained→idle signalling; tests and docs updated accordingly — review tests that awaited drained notifications and any multi-waiter expectations.

🔇 Additional comments (31)
crates/comenqd/src/supervisor/tests.rs (1)

31-34: Excellent improvement to test reliability.

The yield_now() call explicitly ensures the spawned task yields control before completing, guaranteeing it remains active when abort() is called. This eliminates any potential race condition where an empty async block might complete before cancellation, making the test helper more deterministic and robust.

crates/comenqd/tests/supervisor.rs (1)

70-70: LGTM! Test improvements align with coding guidelines and fix construction issues.

The changes improve code quality and test reliability:

  • Line 70: The explicit variable name in the format string ({timeout_duration:?}) improves clarity over the positional {:?}.
  • Line 89: Removing unnecessary mut qualifiers correctly reflects that the makers are consumed when moved into supervise_until_restarts, not mutated in this scope. This aligns with the guideline to "avoid unnecessary mut bindings".
  • Lines 151-152: Passing the boxed closures directly is cleaner than wrapping them in additional move || closures. Since Box<dyn FnMut()> implements FnMut(), it satisfies the generic trait bounds. This addresses the construction interference mentioned in the PR objectives.

Also applies to: 89-89, 151-152

.config/nextest.toml (3)

3-4: Clarify whether terminate-after = 1 is intentional.

The current configuration terminates the entire test run after the first slow test exceeds 60 seconds. This might not align with expectations in a parallel test environment where you may want to kill slow individual tests but continue running others.

If you intend to kill only slow tests without stopping the entire run, set terminate-after to a higher value or remove it entirely. If the current behaviour is intentional (fail-fast on any slow test), clarify the comment to reflect that.


6-7: LGTM!

The 10-minute global timeout provides a reasonable safety net for CI runs whilst allowing sufficient time for parallel test execution.


9-11: LGTM!

The filter correctly excludes cucumber binaries from nextest runs, aligning with the Makefile's separate cucumber test invocations. The comments clearly explain the rationale.

Makefile (5)

6-6: LGTM!

Adding --workspace to CLIPPY_FLAGS ensures consistent workspace-wide linting, aligning with the test target changes.


7-7: LGTM!

Updating to markdownlint-cli2 adopts the actively maintained version of the tool.


37-38: LGTM!

The two-step test invocation correctly separates nextest-compatible tests from cucumber tests, maintaining workspace scope and build parallelism for both. This aligns perfectly with the nextest configuration.


42-43: LGTM!

The coverage targets correctly use cargo llvm-cov nextest for the main test suite and accumulate cucumber coverage with --no-clean, maintaining the coverage threshold for both.


48-49: Verify that separate LCOV output files align with CI expectations.

The target generates two separate LCOV files (lcov.info and lcov-cucumber.info). If your CI workflow or coverage upload tools expect a single merged file, merge the cucumber coverage into the main file using --output-path coverage/lcov.info for both invocations (with --no-clean on the second).

Review the CI workflow's coverage step to confirm whether it consumes one file or multiple.

test-support/src/workflow.rs (2)

86-88: LGTM!

The inline variable interpolation {EXPECTED_RUST_BUILDER} is cleaner than separate format arguments and makes the test YAML more readable.


113-114: LGTM!

Consistent with the other test case—inline interpolation improves readability.

crates/comenqd/src/logging.rs (1)

110-119: LGTM!

The test correctly uses init_with_writer_and_filter to avoid environment mutation, complying with coding guidelines that forbid direct environment access in tests.

crates/comenqd/src/util.rs (1)

10-10: LGTM!

Adding "send.lock" to METADATA_FILE_NAMES ensures queue emptiness detection ignores this sentinel file, aligning with the PR objective to fix worker shutdown semantics.

crates/comenqd/src/listener.rs (1)

31-31: LGTM!

Doc example path correctly updated to reflect the namespace reorganisation.

crates/comenqd/tests/retry_helper.rs (4)

13-30: LGTM!

Explicit with_ci(false) and with_coverage(false) flags replace environment mutation, ensuring deterministic test behaviour and compliance with coding guidelines.


32-49: LGTM!

Both tests correctly use explicit flags. The new calculate_timeout_scales_with_coverage test provides good coverage for the coverage multiplier logic.


51-77: LGTM!

Tests updated to use explicit configuration flags, avoiding environment mutation.


79-133: LGTM!

Async tests consistently use explicit flags for deterministic behaviour.

crates/comenqd/tests/util.rs (3)

25-38: LGTM!

The new optional ci and coverage fields with None defaults enable explicit flag-driven test configuration while preserving environment fallback behaviour.


68-77: LGTM!

The fallback logic correctly prioritises explicit field values over environment variable reads, enabling deterministic testing.


125-125: LGTM!

Using let _ = ... is idiomatic for explicitly discarding unused values.

crates/comenqd/tests/daemon.rs (4)

7-10: LGTM!

Removing is_metadata_file from the public re-export aligns with the internal handling of metadata file recognition.


280-306: LGTM!

The diagnostic formatting improvements with embedded variables are cleaner and more readable.


308-372: LGTM!

The switch from drained to idle notification aligns with PR objectives for single-waiter semantics and idle-based signalling. The explanatory comments about yaque's lazy cleanup are helpful.


374-442: LGTM!

Relaxed assertions allow multiple HTTP attempts while correctly verifying that at least one request occurred and the queue retains data after failure.

crates/comenqd/src/worker.rs (5)

16-21: LGTM!

Expanding conditional imports to include feature = "test-support" enables configurable test-support gating outside unit tests.


83-96: LGTM!

The notify_drained_if_empty function is correctly gated with cfg(any(test, feature = "test-support")) and uses notify_one() consistently.


98-134: LGTM!

The wait_or_shutdown function now returns a bool indicating shutdown (true) or timeout (false). Documentation is clear with accurate examples demonstrating both paths.


166-237: LGTM!

The run_worker loop correctly uses:

  • Biased select prioritising shutdown over message reception for responsive graceful shutdown.
  • New wait_or_shutdown return semantics to break on shutdown signal.
  • Test-support gated notify_drained_if_empty calls.

The control flow is clear and handles all paths correctly.


70-81: Single-waiter semantics confirmed—no downstream issues identified.

The change to notify_one() is correct. Verification confirms downstream test code creates only isolated single-waiter scenarios on these Notify objects. Each test clones the Arc once and awaits .notified() exactly once. No code expects multiple simultaneous notifications.

Comment thread .github/workflows/ci.yml Outdated

80-106: Single-waiter semantics now documented.

Summary of additional repo context relevant to reviewing PR #125:

  • Architecture & worker behavior: daemon uses a three-task model (run_listener, queue_writer, run_worker); run_worker dequeues via yaque::RecvGuard, posts with octocrab (10s per-request timeout) and always sleeps cooldown after each attempt — changes to wait/notify/shutdown affect core loop semantics.

  • Queue semantics & metadata: persistent transactional queue (yaque) — guard.commit() removes items; dropping guard requeues. METADATA_FILE_NAMES change (send.lock) directly impacts queue-empty detection and tests relying on metadata checks.

  • Notifications & tests: test infrastructure uses test-support utilities (EnvVarGuard, wait_for_file, SOCKET_RETRY_COUNT/DELAY), BDD worlds (WorkerWorld/ListenerWorld) and wiremock for GitHub API mocks — modifications from notify_waiters→notify_one and drained→idle require updating those worlds/tests.

  • Testing & CI tooling: CI switched to nextest (workflow installs nextest) and coverage uses llvm-cov; Makefile changes to run nextest and separate cucumber runs must align with .github/workflows/ci.yml and .config/nextest.toml settings.

  • Public API/tests surface: logging API added init_with_writer_and_filter to avoid env mutation; worker::wait_or_shutdown signature now returns bool — callers and tests in the workspace may need updates.

  • Recommended review focus areas derived from repo context:

    • Ensure run_worker control flow correctly interprets new wait_or_shutdown bool and still preserves transactional behavior (guard.commit/drop).
    • Verify all tests/worlds updated to use idle notifications and that notify_one semantics are safe (no multi-waiter assumptions).
    • Confirm METADATA_FILE_NAMES update is exercised by unit tests and by any integration tests verifying queue emptiness.
    • Check CI/workflow and Makefile nextest/version consistency with installed nextest action and .config/nextest.toml filters (cucumber exclusion).
    • Validate new logging API usage in tests avoids global env mutation and that public docs/examples updated accordingly.

crates/comenqd/tests/util.rs (4)

25-28: LGTM! Well-designed optional fields for dependency injection.

The optional flags with clear documentation enable tests to avoid environment reads, aligning with the coding guidelines' preference for dependency injection over environment access.


36-37: LGTM! Correct field initialization.

The None initialization allows proper fallback to environment variables in calculate_timeout.


66-75: LGTM! Correct prioritisation of explicit flags over environment.

The implementation correctly prioritises explicit flags (set via builder methods) whilst maintaining backwards compatibility via environment variable fallbacks. Reading the environment via std::env::var is safe; the coding guidelines' unsafe requirement applies only to set_var and remove_var.


123-123: LGTM! More idiomatic pattern for intentionally unused values.

The let _ = ... pattern is more idiomatic than drop(...) for intentionally ignoring values whilst still ensuring construction succeeds.

crates/comenqd/src/worker.rs (5)

16-21: LGTM!

The cfg guards correctly gate test utilities under both test and test-support feature, enabling external crates to leverage these utilities.


55-78: LGTM!

The documentation clearly explains single-waiter semantics for each hook, and the #[expect(dead_code, ...)] attribute properly addresses the lint suppression guidelines with a descriptive reason.


108-145: LGTM!

The wait_or_shutdown method correctly uses a biased select to prioritise shutdown signals, and the return value semantics are clearly documented. The examples effectively demonstrate both timeout and shutdown scenarios.


185-248: LGTM!

The run_worker loop correctly implements shutdown-aware behaviour:

  • Biased select prioritises shutdown over queue receive
  • Malformed message handling now respects shutdown during cooldown (lines 208-210)
  • Post-processing cooldown respects shutdown (lines 241-243)
  • Final notify_drained_if_empty call ensures clean exit signalling

This fixes the prior bug where the worker would not exit when shutdown occurred during cooldown.


250-286: LGTM!

The unit tests comprehensively cover wait_or_shutdown semantics:

  • Timeout expiry returns false
  • Shutdown signal returns true
  • Biased select prioritises shutdown over timeout

Tests correctly use .expect() per coding guidelines.

crates/comenqd/src/logging.rs (2)

64-72: Implementation is correct.

The function properly constructs the subscriber with an explicit filter via EnvFilter::new(filter), avoiding environment variable dependency. The logic mirrors init_with_writer appropriately.


116-117: Excellent update to avoid environment mutation.

The test now uses init_with_writer_and_filter with an explicit filter parameter, avoiding environment variable mutation that would be unsafe in Rust 2024 per the coding guidelines.

Based on coding guidelines: "Environment access (env::set_var and env::remove_var) are always unsafe in Rust 2024 and MUST be marked as such."

crates/comenqd/src/util.rs (1)

10-10: LGTM — metadata file list correctly extended.

The addition of "send.lock" addresses the bug where queue emptiness detection incorrectly treated send.lock as a data file.

crates/comenqd/tests/fixtures/github_error_response.json (1)

1-4: LGTM — fixture extracted as requested.

Minimal GitHub API error response fixture, correctly structured for error-path tests.

crates/comenqd/tests/fixtures/github_comment_response.json (1)

1-30: LGTM — comprehensive GitHub comment response fixture.

Realistic structure matching GitHub's issue comment API response. Extraction from inline JSON addresses prior review feedback.

Makefile (4)

6-7: LGTM — workspace-wide clippy and updated markdown linter.

The --workspace flag ensures all crates are linted. Migration to markdownlint-cli2 aligns with modern tooling.


37-38: LGTM — nextest integration with separate cucumber execution.

Correct approach: nextest handles standard tests whilst cucumber runs separately (nextest cannot execute cucumber binaries).


42-43: LGTM — coverage targets properly sequenced.

The --no-clean flag on the cucumber step preserves coverage data from the nextest run, enabling combined coverage reporting.


68-68: LGTM — nixie target restored with file pattern.

The --no-sandbox "**/*.md" invocation addresses the prior review concern about missing file arguments.

crates/comenqd/tests/daemon.rs (8)

7-7: LGTM — import list correctly updated.

Removal of is_metadata_file from the public re-export aligns with the function remaining pub(crate) in util.rs.


149-152: LGTM — builder pattern for TimeoutConfig.

Clean API usage with explicit with_ci and with_coverage calls replacing dead code from previous implementation.


227-232: LGTM — mock expectation relaxed appropriately.

The .expect(1..) allows for retry behaviour whilst still asserting at least one request occurs.


289-296: LGTM — WorkerHooks updated to idle-based semantics.

The switch from drained to idle aligns with the PR objective of single-waiter notification semantics. The drained field is correctly set to None.


301-316: LGTM — test waits for idle notification.

Correctly updated to await idle notification rather than drained, matching the new worker hook semantics.


337-343: LGTM — helpful comment explaining yaque cleanup semantics.

The comment clarifies why queue segment files may persist after logical commit, preventing future confusion about test assertions.


397-413: LGTM — error-path assertions appropriately relaxed.

Asserting "at least one request" rather than "exactly one" accommodates retry behaviour whilst still verifying the worker attempted processing. The queue retention check confirms the job was not committed.


267-272: The let-chains syntax is fully supported. The project uses Rust Edition 2024, which requires Rust 1.85.0 minimum. Let-chains was stabilised in Rust 1.80.0, so no feature gate or special configuration is necessary.

Likely an incorrect or invalid review comment.

.github/workflows/ci.yml (1)

20-23: Nextest installation correctly pinned to a valid action commit.

The SHA db22c42b5af88356329b9a8056bb2c2f026d5a10 references a valid commit in taiki-e/install-action. Version 0.9.114 is confirmed as a released version and addresses the outdated dependency flagged previously.

Summary of additional repository context relevant to reviewing PR #125:

  • Worker/queue behavior

    • run_worker dequeues via yaque::RecvGuard; guard.commit() removes an item, dropping the guard requeues it. Cooldown sleep runs after every attempt (success or failure). Changes to wait_or_shutdown/notify semantics directly affect worker loop and transactional commit/drop semantics.
  • Notifications & tests

    • Tests/worlds (WorkerWorld, ListenerWorld) and test-support utilities rely on drained/idle notifications and Notify usage; switching notify_waiters()→notify_one() changes synchronization semantics that tests and worlds assume. Behavioral tests run concurrently via Cucumber worlds and use test-support helpers (EnvVarGuard, wait_for_file, wiremock). Review must ensure tests updated to match new single-waiter semantics.
  • METADATA_FILE_NAMES impact

    • Queue-empty detection logic relies on metadata filename recognition; adding "send.lock" to METADATA_FILE_NAMES affects what files are considered metadata vs. queue data — tests and queue-empty assertions must reflect this.
  • CI / nextest / coverage changes

    • CI workflow now installs nextest; Makefile and .config/nextest.toml control nextest runs and exclude cucumber binaries from default runs. Coverage uses llvm-cov/LCOV — ensure workflow, Makefile, and .config/nextest.toml are consistent.
  • Logging API change

    • New public init_with_writer_and_filter avoids mutating RUST_LOG in tests; tests were updated to use it for deterministic logging behavior — check public docs/examples updated accordingly.
  • Tests added / needed (per repo testing infra)

    • Test-support crate provides utilities and serialisation guards; behavioral tests are executed in parallel worlds. PR should include unit and behavioural tests for:
      • notify_one semantics (exactly one waiter woken; buffered-permit behavior)
      • wait_or_shutdown return-value cases (timeout vs shutdown)
      • worker termination when shutdown occurs during cooldown or after malformed messages
      • is_metadata_file recognition for "send.lock"

.markdownlint-cli2.jsonc (1)

13-21: Ignores configuration addresses review feedback.

The ignores array correctly excludes **/target/**, .terraform/**, .uv-cache/**, and other generated directories. This resolves the concern raised in PR comments about the markdownlint target including generated files.

crates/comenqd/tests/daemon.rs (7)

7-7: Public API surface correctly reduced.

The removal of is_metadata_file from the public re-export aligns with keeping implementation details internal whilst maintaining the necessary public surface for WorkerControl, WorkerHooks, and listener components.


219-226: Fixture extraction correctly implemented.

The external JSON fixtures loaded via include_str! address the prior review feedback about inline data blocks. The status-based branching cleanly separates success and error response handling.


280-344: Worker success test correctly updated for idle-based synchronisation.

The test now uses idle notifications instead of drained, matching the updated single-waiter semantics. The explanatory comment about yaque's lazy segment cleanup (lines 340–343) clarifies why queue file assertions are relaxed—this is helpful context for future maintainers.


397-405: Relaxed assertion allows for retry semantics.

The change from exact count to "at least one request" appropriately accounts for potential retry behaviour whilst still proving the worker attempted processing. The accompanying comment clarifies intent.


415-519: Behavioural tests for shutdown during cooldown address review feedback.

These tests validate the critical fix where wait_or_shutdown now breaks out of the worker loop when shutdown is signalled during cooldown. The 60-second cooldown with 2-second assertion timeout proves the worker terminates promptly rather than waiting the full cooldown period.


521-587: Malformed message shutdown test provides complete coverage.

This test exercises the error-handling path where a malformed queue entry is dropped, then verifies both prompt shutdown termination and that no GitHub API requests were made. This completes the behavioural test coverage for the wait_or_shutdown changes.


267-271: Let-chains usage is appropriate for Rust 2024 edition.

The chained if let expression at lines 267–271 uses stabilised Rust 2024 syntax correctly for conditional binding.

crates/comenqd/src/worker.rs (10)

56-78: Single-waiter semantics properly documented.

The documentation now explicitly states that each hook uses notify_one and supports exactly one waiter. The field-level doc comments reinforce this constraint, addressing the review feedback about documenting the notify_waitersnotify_one semantic change.


73-77: Lint suppression now uses #[expect] per coding guidelines.

The cfg_attr correctly applies a narrowly-scoped expect(dead_code, ...) with a descriptive reason, replacing the previously forbidden #[allow].


80-106: Consistent notify_one usage across all hooks.

All three notification methods (notify_enqueued, notify_idle, notify_drained_if_empty) now use notify_one(), matching the documented single-waiter semantics and ensuring consistent behaviour.


108-144: wait_or_shutdown return semantics clearly documented.

The function now returns a bool indicating shutdown (true) vs timeout (false). The biased select ensures shutdown detection takes priority, and the doc examples demonstrate both paths correctly.


186-194: Biased select prioritises shutdown over queue receive.

The biased keyword ensures the shutdown signal is checked before attempting to receive from the queue, preventing the worker from blocking on an empty queue when shutdown is requested.


208-210: Shutdown-aware cooldown fixes the prior bug.

Both cooldown wait points now check the wait_or_shutdown return value and break the loop when shutdown is signalled. This fixes the bug where the worker would not exit when shutdown occurred during cooldown.

Also applies to: 241-243


256-266: Unit test validates timeout returns false.

The test correctly verifies that a zero-second wait returns false immediately. The timing assertion (< 100ms) was previously flagged as potentially flaky under load; if CI issues arise, increase the threshold to 500ms.


287-331: Notify-one semantics test validates single-waiter behaviour.

The test spawns three waiters, sends one notification, and verifies exactly one waiter is woken. This directly validates the documented single-waiter semantics and addresses the review feedback requesting tests for the notify_waitersnotify_one change.


333-356: Buffered permit test validates pre-notification behaviour.

This test confirms that notify_one buffers a permit when no waiters exist, and that subsequent waiters do not receive additional permits. This validates the expected Tokio Notify semantics for the hook implementation.


1-4: Module-level documentation is present and clear.

The module begins with a //! doc comment explaining its purpose (queue worker, dequeue, cooldown enforcement), satisfying the coding guideline requiring module-level documentation.

@coderabbitai Have the following now been resolved?

⚠️ PARTIALLY RESOLVED (1 item)

Comment 5 - Unit tests for wait_or_shutdown exist (lines 268-285 in worker.rs):

wait_or_shutdown_returns_false_on_timeout
wait_or_shutdown_returns_true_on_shutdown
Biased select behaviour test

However, behavioural/integration tests demonstrating worker loop termination on shutdown (during idle or processing) are missing.

Comment 4 - No unit or behavioural tests covering the notify_one semantics change. Integration tests use the hooks but don't verify that exactly one waiter is released or test multi-waiter scenarios.

Comment 6 - No tests demonstrating the shutdown bug fix where the loop breaks during cooldown after malformed messages or between iterations.

@coderabbitai please create new GitHub issues for the following:

  • tests/steps/config_steps.rs:136 — the drop order currently releases env_guard before socket_guard (if let Some(_guard) = self.env_guard.take() { ... }). If a future scenario sets COMENQD_SOCKET_PATH before calling
    config_file_with_token, the current order could re‑introduce the env var on drop. Consider dropping socket_guard first or consolidating guards for the same key to avoid ordering surprises.
  • crates/comenqd/src/worker.rs:305-352 — the new notify tests use tight timeouts (Duration::from_millis(50) / 100) which can reintroduce flakiness under load. Consider using the existing TimeoutConfig helper or slightly
    larger bounds to keep intent but reduce scheduling sensitivity.

These tight timeouts can reintroduce test flakiness under load or on slower CI runners, particularly when multiple tests run concurrently. Scheduler delays or system load could cause legitimate test failures.

Learning: In Rust code, when encountering the pattern:
```rust
#[allow(unfulfilled_lint_expectations, reason = "...")]
#[expect(dead_code, reason = "...")]
```
Recommend replacing it with:
```rust
#[cfg_attr(not(any(...)), expect(dead_code, reason = "..."))]
```
This uses conditional compilation to apply the `expect` attribute only when needed, avoiding the forbidden `#[allow]` attribute while properly handling cross-crate test utility usage scenarios.

Summary of additional repository facts relevant to reviewing PR #125:

  • nextest / CI: repo uses cargo-nextest in CI; .github workflow installs nextest and build/test pipeline expects nextest-driven coverage (CI workflow and testing docs reference nextest/coverage steps).
  • Tests & test-support: project runs extensive BDD tests via cucumber worlds (tests/cucumber.rs) using test-support utilities (EnvVarGuard, wait_for_file, octocrab_for, SOCKET_RETRY_*). Worker/Listener worlds rely on Notify-based synchronization and file/socket polling helpers. Changes to notify semantics (notify_waiters → notify_one) directly affect these worlds.
  • Worker/queue semantics: run_worker uses yaque::RecvGuard transactional dequeue → guard.commit() on success, drop→requeue on failure; worker always sleeps cooldown after each attempt. wait_or_shutdown now returns bool (shutdown signal) and tests / worker loop behavior depend on that return value.
  • METADATA filenames / queue emptiness: queue-empty detection treats certain names as metadata; adding "send.lock" alters what is considered metadata and therefore emptiness checks in tests and runtime.
  • Logging API & tests: logging API added init_with_writer_and_filter gated behind test-support to avoid mutating RUST_LOG in tests; tests were updated to use deterministic writer+filter.
  • CI/test expectations & reviewer concerns (from repo docs): reviewers asked for explicit tests for single-waiter notify semantics, shutdown-during-cooldown behavior, Makefile markdownlint/nixie file globs/ignores; repo testing/docs indicate behavioral tests must be updated accordingly.

🔇 Additional comments (13)
.markdownlint-cli2.jsonc (2)

3-11: LGTM: Markdownlint rule configuration is appropriate.

The MD rule configurations are sensible defaults. The addition of "headings": false to MD013 and the removal of MD040 align with the project's documentation style.


13-20: Good addition: Ignores array addresses reviewer feedback.

The ignores array appropriately excludes generated and third-party directories, addressing the concern raised about the Makefile markdownlint target changes.

crates/comenqd/src/util.rs (2)

10-10: LGTM: Metadata extension correctly includes send.lock.

The addition of "send.lock" to the metadata list aligns with the PR objective to treat send.lock as queue metadata, ensuring it does not prevent emptiness detection. The change is well-tested by the new unit tests below.


27-50: Excellent test coverage using rstest parameterisation.

The test suite correctly addresses the previous review feedback by consolidating duplicated tests into parameterised cases. The implementation covers all metadata files (version, recv.lock, send.lock) and validates rejection of non-metadata names (queue segments, arbitrary files, empty strings).

crates/comenqd/src/worker.rs (4)

55-78: LGTM: Single-waiter semantics properly documented.

The WorkerHooks documentation clearly explains that each hook uses notify_one and supports exactly one waiter per hook. This addresses the previous review concern about the semantic change from broadcast to single-waiter notification. The implementation is backed by comprehensive tests below.


108-144: Excellent shutdown semantics with clear return value.

The updated signature returning bool makes shutdown detection explicit and self-documenting. The biased select ensures shutdown takes priority over timeout, and the documentation includes working examples demonstrating both timeout and shutdown scenarios.


186-244: Shutdown-aware control flow correctly implemented.

The worker loop now properly responds to shutdown signals at all wait points:

  • Pre-dequeue (lines 186-194)
  • Post-malformed-message cooldown (lines 208-210)
  • Post-processing cooldown (lines 241-243)

This ensures the worker exits promptly when shutdown is signalled, addressing the PR objective to improve worker shutdown semantics.


250-357: Comprehensive test coverage validates shutdown and notification semantics.

The test suite thoroughly validates:

  • wait_or_shutdown_returns_false_on_timeout: Confirms timeout behaviour with appropriate 500ms threshold (addressing flakiness concern)
  • wait_or_shutdown_returns_true_on_shutdown: Validates shutdown detection
  • wait_or_shutdown_prioritises_shutdown_over_timeout: Confirms biased select semantics
  • notify_one_wakes_exactly_one_waiter: Proves single-waiter behaviour with three waiters and atomic counting
  • notify_one_buffers_permit_when_no_waiters: Validates permit buffering semantics

The tests provide strong evidence that the notification and shutdown changes behave correctly.

crates/comenqd/src/logging.rs (2)

1-76: LGTM: Logging API correctly implements test-support gating.

All previous review concerns have been addressed:

  • Documentation uses en-GB spelling ("Initialise/initialised") throughout
  • The init_with_writer_and_filter function is properly gated behind #[cfg(feature = "test-support")]
  • Lint suppression uses #[expect] instead of the forbidden #[allow]
  • The explicit filter parameter enables deterministic test behaviour without environment mutation, aligning with the coding guidelines that forbid unsafe env::set_var in Rust 2024

The implementation provides a clean test-support API for logging configuration.


78-127: Excellent test implementation avoiding environment mutation.

The test correctly uses init_with_writer_and_filter with an explicit filter ("info") rather than mutating RUST_LOG, complying with the coding guideline that environment mutations in tests must be avoided. The custom BufMakeWriter/BufWriter implementation provides deterministic log capture for assertions.

crates/comenqd/tests/util.rs (3)

25-53: LGTM: Builder pattern correctly implemented with explicit flag controls.

The addition of ci and coverage fields with corresponding builder methods provides clean control over timeout multipliers without environment dependency. The implementation correctly:

  • Uses Option<bool> to distinguish "not set" from explicit true/false
  • Marks builders with #[must_use] to catch unused results
  • Uses const fn for compile-time construction where possible
  • Provides clear documentation

This addresses the PR objective to allow configurable test-support behaviour.


66-79: Correct fallback logic for environment-derived multipliers.

The calculate_timeout implementation properly respects explicit flags when provided, falling back to environment variables (LLVM_PROFILE_FILE for coverage, CI for ci) only when the corresponding Option is None. This allows tests to avoid environment reads whilst maintaining backward compatibility for code that doesn't use the explicit flags.


126-199: Comprehensive test coverage validates builder semantics.

The test suite thoroughly addresses the previous review request by covering:

  • with_ci_true_applies_multiplier: Validates CI multiplier application
  • with_coverage_true_applies_multiplier: Validates coverage multiplier application
  • explicit_flags_override_environment: Confirms explicit flags take precedence
  • ci_and_coverage_multipliers_stack: Proves multipliers compose correctly

All tests use explicit flags (.with_ci(false).with_coverage(false)) to establish deterministic baselines, avoiding environment dependency. The assertions validate exact numeric relationships between base and multiplied timeouts.

Move the test-only logging function from comenqd to test-support where it
belongs. This eliminates the need for lint suppression annotations since the
function is now unconditionally compiled in the test-support crate.

Changes:
- Add tracing-subscriber dependency to test-support
- Create test-support/src/logging.rs with the function
- Export logging module from test-support/src/lib.rs
- Remove function from comenqd/src/logging.rs
- Update comenqd logging tests to use test_support::logging

Summary of additional facts relevant to reviewing PR #125:

  • CI already installs and uses cargo-nextest in workflows; adding .config/nextest.toml and separate cucumber exclusions aligns with CI expectations (workflow installs nextest).
  • Tests rely on test-support utilities: EnvVarGuard, wait_for_file (with SOCKET_RETRY_COUNT / SOCKET_RETRY_DELAY), octocrab_for, temp_config — timing-sensitive tests should use these helpers to reduce flakiness.
  • The persistent queue uses yaque::Receiver/RecvGuard transactional semantics: guard.commit() removes an item; dropping guard auto-requeues — changing METADATA_FILE_NAMES (adding "send.lock") affects emptiness detection and queue-cleanup assertions.
  • run_worker enforces a per-request timeout (10s) and applies a fixed cooldown after each attempt; wait_or_shutdown returning bool directly controls loop exit on shutdown — tests verifying shutdown-during-cooldown must assert loop break behavior.
  • Listener/worker synchronization uses tokio Notify; switching notify_waiters() → notify_one() changes from broadcast to single-waiter semantics and can starve other waiters unless single-waiter behavior is intended and documented — tests should assert exactly-one-wakeup and buffered-permit behavior when no waiters exist.
  • init_with_writer_and_filter was moved to test-support and test-support now adds tracing-subscriber; tests were updated to use test-support logging to avoid mutating RUST_LOG in tests.
  • Makefile / tooling cautions: markdownlint and nixie invocation changes may expand lint/sanity scope (include generated files); reviewer guidance to add ignore globs or explicit file lists remains applicable.
