Subject: HTTP/2: close connections initialized during graceful shutdown.
X-Git-Tag: release-1.27.1~9
X-Git-Url: http://www.kaiwu.me/postgresql/commit/static/gitweb.js?a=commitdiff_plain;h=145b228530c364452c14d3184f1eee5e09b324aa;p=nginx.git

HTTP/2: close connections initialized during graceful shutdown.

In some rare cases, graceful shutdown may happen while initializing an HTTP/2
connection.  Previously, such a connection ignored the shutdown and remained
active.  Now it is gracefully closed prior to processing any streams to
eliminate the shutdown delay.
