Olivier Houchard 1662cdb0c6 BUG/MEDIUM: connections: Set the tid for the old tasklet on takeover. ... In the various takeover() methods, make sure we schedule the old tasklet on the old thread, as we don't want it to run on our own thread! This was causing a very rare crash when building with DEBUG_STRICT, seeing that either an FD's thread mask didn't match the thread ID in h1_io_cb(), or that stream_int_notify() would try to queue a task with the wrong tid_bit. In order to reproduce this, it is necessary to maintain many connections (typically 30k) at a high request rate flowing over H1+SSL between two proxies, the second of which would randomly reject ~1% of the incoming connection and randomly killing some idle ones using a very short client timeout. The request rate must be adjusted so that the CPUs are nearly saturated, but never reach 100%. It's easier to reproduce this by skipping local connections and always picking from other threads. The issue should happen in less than 20s otherwise it's necessary to restart to reset the idle connections lists. No backport is needed, takeover() is 2.2 only.		2020-07-03 17:49:23 +02:00
