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.
"http-request deny", "http-request tarpit" and "http-response deny" rules now
use the same syntax than http return rules and internally rely on the http
replies. The behaviour is not the same when no argument is specified (or only
the status code). For http replies, a dummy response is produced, with no
payload. For old deny/tarpit rules, the proxy's error messages are used. Thus,
to be compatible with existing configuration, the "default-errorfiles" parameter
is implied. For instance :
http-request deny deny_status 404
is now an alias of
http-request deny status 404 default-errorfiles
These are mostly comments in the code. A few error messages were fixed
and are of low enough importance not to deserve a backport. Some regtests
were also fixed.
2 reg tests are added. The first one ensures the declaration of errors in a
proxy is fonctionnal. It declares http-errors sections and declare error files
using the errorfile and the errorfiles directives, both in the default section
and the frontend sections. The second one ensures it is possible to use a custom
error file for an HTTP deny rule.
