7736bbb545* fix(cache): write the completion marker before closing the cache writer Readers of an in-progress cache write see EOF the moment the writer closes, but the .complete marker was created after the close, on the background goroutine — so a fully-read stream did not mean the cache was done touching disk. The new artwork precache spec ends right at EOF, and its GinkgoT().TempDir() cleanup raced the marker creation, failing the Windows CI job with 'unlinkat ...: The directory is not empty' (the race also reproduces on macOS, 2 of 3 runs, with the tightened test). Writing the marker after a clean copy but before Close makes reader-EOF imply every on-disk write for the entry is finished. A failed writer Close still invalidates the entry, which removes both the marker and the data file. The existing marker test now asserts the marker exists immediately at EOF instead of Eventually. * fix(artwork): never dispatch queue items after the drain context is cancelled The 10x Windows stress run for the previous commit surfaced a second flake in the same package: 'leaves undispatched items queued when cancelled mid-batch' lost row alc7 in 4 of 10 runs. In drain, when a semaphore slot is free and the context is already cancelled, both cases of the blocking select are ready and Go picks one at random — so a cancelled drain could still dispatch items. A non-blocking Done check before the select gives cancellation priority. The race was invisible on Linux/macOS only by accident: the spec seeded the album repo with a single album (each SetData overwrote the last), so only the final row (alc7) resolved to absent and got deleted when dispatched; the others fell on the retry path and survived. Nanosecond enqueue timestamps made alc0 always first out of the mock dequeue, masking the race, while Windows' coarse clock ties the timestamps and randomizes the order. The spec now seeds all eight albums, which made the race reproduce locally on the first try (row alc0) and now guards the fix on every platform. * test: give cache-init waits a 10s timeout for loaded CI runners A 10x parallel Windows stress run timed out one artwork spec in BeforeEach: the FileCache init goroutine (mkdir + reload walk) took over Gomega's default 1s Eventually timeout under shared-runner disk contention. Bump the three identical init waits (two artwork suites and the utils/cache helper) to 10s. * test(scanner): widen watcher debounce margins for loaded CI runners The watcher debouncing spec asserts 'no scan yet' inside 20ms Consistently windows while the debounce wait was only 50ms — a 2.5x margin that a loaded Windows runner blows through by delaying the timer-reset notification, firing the scan early (failed all three FlakeAttempts in a 10x stress run). Raise the test debounce wait to 200ms (10x the observation windows) and the scan-fired Eventually timeouts to 2s to match. * refactor(artwork): collapse drain cancellation into a single exit path Replace the non-blocking ctx pre-check plus duplicated select exit with one select and a ctx.Err() check after it. Besides removing the duplication, this closes the residual race: a cancellation landing between the two selects could still let the blocking select randomly pick the free semaphore slot and dispatch the item. Now a dispatch is only possible when the context was live after slot acquisition. * style: trim flaky-test fix comments to single lines Compress each two-line comment added by this PR to the one line that carries the invariant; drop the narration around it. |
