• preview: restore strict 10s request deadline

    LeoVasanko released this 2026-08-13 07:55:48 +00:00 | 1 commits to main since this release

    The mediapreview error-handling refactor dropped the outer
    asyncio.wait_for around preview generation. Pool-internal timeouts only
    bound individual stages (idle-worker wait, worker request, OO HTTP
    calls); queueing on top of them let requests run far past 10s and
    eventually return 200 instead of 503. Wrap both generate paths in
    wait_for(PREVIEW_TIMEOUT) again — cancellation propagates correctly:
    the pool dispatcher drops cancelled futures, and the OnlyOffice manager
    cancels orphaned conversion tasks.
