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.
Its sole remaining purpose was to display "proxy foo started", which
has little benefit and pollutes output for those with plenty of proxies.
Let's remove it now.
The VTCs were updated to reflect this, because many of them had explicit
counts of dropped lines to match this message.
This is tagged as MEDIUM because some users may be surprized by the
loss of this quite old message.
A few regtests continue to regularly fail in highly loaded VMs because
they have very short timeouts. Actually the goal of running with short
timeouts was to make sure we do not uselessly wait during tests designed
to trigger them, but these timeouts here are never supposed to fire at
all, so they don't need to be kept in the 15-20ms range. They do not
pose any issue on any regular machine, but VMs are often suffering from
huge time jumps and cannot always produce responses in that short of a
time.
Just like with commit ce6fc25b1 ("REGTEST: increase timeouts on the
seamless-reload test"), let's raise these short timeouts to 1 second.
A few other ones remain set to 150-200ms and do not seem to cause any
issue. Some are actually expected to trigger so let's not touch them
for now.
Some reg tests and their dependencies have been renamed. They may be
referenced by the .vtc files. So, this patch modifies also the references
to these dependencies.
