https://github.com/apache/httpd/pull/293
is the PR that contains the changes I just reverted
in trunk regarding the non-blocking SSL handshake.
I did not like to revert a set of changes by anyone
here. But our trunk CI is failing for some time now
and I felt this needs to be analyzed without interfering
with other ongoing work.
CI FAILURES observed:
1. test_h2_105_02 in test/modules/http2 fails reliably.
Background: the test verifies that the mod_reqtimeout
handshake configuration works.
Failure: mod_reqtimeout has no chance to apply its
timeout in the nonblocking ssl handshake.
2. test_h2_106_02 in test/modules/http2 fails sometimes.
Background: the test sets "MaxRequestsPerChild 3" and
"ServerLimit 2" and fires a sequence of requests on
each time a new connection. The expected outcome is
that all requests succeed, even though the server
is restarting child processes.
Failure: sometimes, request fail during the SSL
handshake. I assume the connection gets accepted, but
is not honored in regard to a graceful shutdown of
the child.
3. Travis CI test report errors in the log that seem to
be caused by the changes. The errors are:
[,,,] [mpm_event:error] [pid 51102:tid 140555589760768] (9)Bad file
descriptor: AH03465: process_socket: apr_pollset_add failure for write
completion
Isolating the changes in a separate branch will allow
us to see if these changes are connected to this or if
another trunk revision caused this.
I hope we can have a working CI in trunk soon and find a
way forward to apply these changes.
Thank you,
Stefan
