Subject: HTTP/3: graceful shutdown on keepalive timeout expiration.
X-Git-Tag: release-1.27.5~11
X-Git-Url: http://www.kaiwu.me/postgresql/commit/?a=commitdiff_plain;h=3a97111adfb6e538ddef1828bbf04a35a8915c1f;p=nginx.git

HTTP/3: graceful shutdown on keepalive timeout expiration.

Previously, the expiration caused QUIC connection finalization even if
there are application-terminated streams finishing sending data.  Such
finalization terminated these streams.

An easy way to trigger this is to request a large file from HTTP/3 over
a small MTU.  In this case keepalive timeout expiration may abruptly
terminate the request stream.
