With the CI occasionally slowing down, we're starting to see again some
spurious failures despite the long 1-second timeouts. This reports false
positives that are disturbing and doesn't provide as much value as this
could. However at this delay it already becomes a pain for developers
to wait for the tests to complete.
This commit adds support for the new environment variable
HAPROXY_TEST_TIMEOUT that will allow anyone to modify the connect,
client and server timeouts. It was set to 5 seconds by default, which
should be plenty for quite some time in the CI. All relevant values
that were 200ms or above were replaced by this one. A few larger
values were left as they are special. One test for the set-timeout
action that used to rely on a fixed 1-sec value was extended to a
fixed 5-sec, as the timeout is normally not reached, but it needs
to be known to compare the old and new values.
When a default-server line specified a client certificate to use, the
frontend would not take it into account and create an empty SSL context,
which would raise an error on the backend side ("peer did not return a
certificate").
This bug was introduced by d817dc733e in
which the SSL contexts are created earlier than before (during the
default-server line parsing) without setting it in the corresponding
server structures. It then made the server create an empty SSL context
in ssl_sock_prepare_srv_ctx because it thought it needed one.
It was raised on redmine, in Bug #3906.
It can be backported to 2.4.
