Pushed d148580 after replaying the telemetry change onto merged #4527 (main 3202923). The former prerequisite merge history and unrelated API edits are gone from this PR. Dependency-result transfer now measures actual reference fetch/cache waits separately from deserialization and application. Master and remote worker instrumentation preserves bounded concurrency, scheduling priorities, cancellation, accepted-result handling, and the independent failure-publication window. Added coverage for overlapping worker intervals and telemetry on successful/failure results; serialization includes enqueue and dependency-transfer timing. Both CodeRabbit test findings are addressed: the stale-heartbeat race uses the dedicated-thread implementation already merged through #4527, and the heartbeat-refresh test seeds an older stored timestamp instead of depending on a 10 ms delay. The full SignalR run also exposed a distinct shutdown race: an intentionally pending result invocation can keep graceful shutdown alive for 30 seconds, exceeding the test's 15-second deadline before restart. The test now sets a one-second host shutdown timeout while preserving the real disconnect/reconnect and result assertions. It passes without changing production shutdown behavior. Validation: 204 distributed + 68 SignalR + 156 report/console tests passed; core Release build 0 warnings/errors; API analyzer gate passed with pre-existing RS0026/RS0041 warnings; 61 baseline checks passed; docs install/build passed. An initial simultaneous core/SignalR test build collided on a compiler output file; the core run passed when executed sequentially. Scoped warning-level formatting verification passed. Information-level verification still reports existing executor/reporting suggestions and is not claimed green; the previously recorded full-format 2 GB limit remains deferred to CI. |
Greptile SummaryThe PR adds distributed execution telemetry and schema-v5 reporting for module timing, worker activity, and fleet utilization.
Confidence Score: 5/5The PR appears safe to merge because no blocking failure remains in the eligible follow-up review scope. No blocking failure remains.

Pushed 07497f9 with both timing findings fixed. The pool stamps each completed dequeue before waiting for a concurrency slot, then passes that timestamp into both master and remote execution timers. A controlled-time regression reproduces a one-hour slot wait without adding it to queue wait. Dependency fetch/processing tests now advance a FakeTimeProvider through the existing coordinator and result-registry seams and assert exact durations (2 seconds fetching once, 6 seconds processing twice), eliminating wall-clock resolution assumptions. Also removed the unused AssignedAt fallback noted in issuecomment-5660364251; assignment telemetry now uses the enqueue timestamp already set by the publisher. All 205 distributed tests and 68 SignalR tests pass. The final focused 12-test run passes after parameter-order cleanup. Both timing regressions failed before their fixes. Core Release build has zero warnings/errors. Scoped warning-level formatting verification and information-level test formatting pass. Existing source logging/unused-parameter suggestions remain disclosed, and the earlier full-format 2 GB limit is still deferred to CI. Public API and documentation are unchanged by this follow-up; their prior validation remains recorded in the PR body. |
Review: distributed utilization and queue-wait telemetry (#4567), head
|
1 participant
Distributed run reports now show which worker executed each module, queue wait, execution time, dependency-result fetch and processing, artifact transfer, and result collection. Schema v5 adds per-worker busy/idle intervals and fleet utilization, and the console identifies the longest queue wait.
The worker pool captures claim time immediately after dequeue and carries it through concurrency-slot waiting to both master and remote execution. Controlled-time tests distinguish this wait from queue time and verify exact dependency-fetch and processing durations, including the once-per-run dependency cache. Assignment telemetry uses the publisher's enqueue timestamp directly.
The implementation builds on merged #4527 and retains reference-based dependency results, scheduling priorities, bounded concurrent workers, cancellation-aware execution, and the independent failure-publication window. Concurrent module intervals count once toward worker busy time. Cross-host queue and result timing assumes synchronized clocks; negative differences are clamped to zero.
Closes #4392
Latest validation: all 205 distributed tests and 68 SignalR tests pass. Both timing regressions reproduced before the fix. The core Release build passes with zero warnings/errors. The preceding implementation also passed 156 report/console tests, the public API analyzer build (with existing RS0026/RS0041 warnings), all 61 package baseline checks, and Node 24.14.1
yarn install/yarn build. This follow-up changes no public API or documentation.Formatting ran on the affected core solution and test project. Scoped warning-level verification passes, and information-level verification passes for the two modified test files. Information-level verification still reports existing unused-parameter and logging suggestions in the executors and dependency helper; it is not reported as passing. The earlier full-format 2 GB guard limit remains deferred to CI.
