tls_basic_sync_wo_stkt_backend fails once every 200 runs for me. This
seems to be because the startup delay doesn't always allow peers to
perform a simultaneous connect, close and new attempt. With 3s I can't
see it fail anymore. In addition the long "delay 0.2" are still way too
much since we do not really care about the startup order in practice.
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.
Absolute path must be used, otherwise, the requests are rejected by HAProxy
because of the recent changes. In addition, the configuration has been slightly
updated to remove warnings at startup.
