Backport #3564: Verify stream completion on clean EOF in the reconnecting framed reader - #3588
Merged
Conversation
…er (#3564) Long live reads were ending silently at the server's 2-minute connection cap: the max-duration abort reaches the client as a clean EOF on some transport paths, and the reader read that as end-of-stream. On EOF it now consults `streams.getInfo` and reconnects from the next chunk unless the stream is done and every chunk up to the tail was delivered. A failed metadata read trusts the EOF, so a transient blip can't fail a healthy completion. Tests added for the reconnect, verified-completion, metadata-failure, and reconnect-budget paths. --------- Signed-off-by: Alex Langenfeld <alex.langenfeld@vercel.com> Signed-off-by: Alex Langenfeld <alexlangenfeld@gmail.com>

Automated backport of #3564 to
stable(backport job run).AI recommendation: This is a data-loss/correctness fix:
createReconnectingFramedStreamtrusted a clean EOF as end-of-stream, so long live reads were silently truncated when the server's max-duration abort arrived as a graceful close. The buggy code exists verbatim onstable(packages/core/src/serialization.ts:691, including the "Clean EOF — stream is truly complete" branch), andstablehas an equivalent metadata API (World.getStreamInfo(name, runId)returning{ tailIndex, done }) the fix can use, though the call site differs from main'sworld.streams.getInfo(runId, name)and will need adapting. Changeset is apatchto@workflow/coreand the only other file is an accompanying test.Merge conflicts were resolved by AI (opencode with
