97da9993d7* fix(stream): abort the response when a transcoded stream is truncated When a transcode failed after some audio had already been sent, Serve logged the error and returned nil, so Go finished the chunked body normally and the client received an apparently complete, silently short file. Symfonium users hit this on large offline syncs, and the worst path, ffmpeg dying mid-write behind the transcoding cache, produced no error and nothing in the log above Debug: the cache writer was closed plainly, so readers drained the truncated entry to a clean EOF. The root cause of that silence is an fscache limitation: Close is the only way to end a cache write, and Close always means "complete". This adopts the deluan/fscache fork, which adds CloseWithError: on failure copyAndClose now cancels the entry with the cause, so every attached reader fails mid-read with the real error instead of EOF, a late Get for the entry is refused, and the entry never reports a final size. The error travels inside the entry each reader holds, which makes per-generation delivery automatic and needs no bookkeeping on our side. With the failure arriving in-band, one change in Serve covers every mode: an io.Copy error after bytes are on the wire panics with http.ErrAbortHandler. Go aborts the response without the terminating chunk (RST_STREAM on HTTP/2), chi's Recoverer re-panics that value, and the deferred stream.Close() still runs, so the transcode limiter slot is released as before. Two behaviors improve as side effects. A transcoder that dies before its first byte now yields a Subsonic error response instead of a 200 with an empty body, since the failure reaches Serve as an error while the status is still unsent; genuinely empty output (clean EOF, exit 0) keeps the 200. And a failed entry's invalidation no longer defers its unlink past a replacement entry re-creating the same file, because canceling already closed its readers. * fix(cache): warn when the cache writer cannot report failures to readers The CloseWithError capability comes from the fscache fork via a go.mod replace directive, and a type assertion picks it up. If that directive is ever lost, the assertion fails silently, readers of a dead writer go back to draining a truncated entry to a clean EOF, and nothing says so. Two layers against that: a warning on the failure path when the writer lacks the capability, and a test that asserts the writer fscache returns carries it, so losing the fork fails CI instead of a listener's download. * build: point the fscache replace at the fork's master deluan/fscache#1 is merged; pin the merge commit instead of the review branch. Pinned by sha because the module proxy still resolves the fork's master ref to its pre-merge commit. * build: reference the upstream fscache PR in the replace comment The replace itself must keep pointing at the fork: the commit only exists in djherbis/fscache under refs/pull/22/head, which the Go module fetcher cannot resolve (verified: unknown revision for both short and full sha). The same commit is advertised on the fork's master, so that is the fetchable source. |
