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.
Some tests expect a 503, typically those that check that wrong CA/CRL
will not be accepted between a server and a frontend. But such tests
tend to last very long simply because of the 1-second turn-around on
connection retries that happens during the failure. Let's properly set
the retries count to zero for these ones. One test purposely wants to
exhaust the retries so the retries was set to 1 instead.
If the first active line of a crt-list file is also the first mentioned
certificate of a frontend that does not have the strict-sni option
enabled, then its certificate will be used as the default one. We then
do not want this instance to be removable since it would make a frontend
lose its default certificate.
Considering that a crt-list file can be used by multiple frontends, and
that its first mentioned certificate can be used as default certificate
for only a subset of those frontends, we do not want the line to be
removable for some frontends and not the others. So if any of the ckch
instances corresponding to a crt-list line is a default instance, the
removal of the crt-list line will be forbidden.
It can be backported as far as 2.2.
