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.
The http-error directive can now be used instead of errorfile to define an error
message in a proxy section (including default sections). This directive uses the
same syntax that http return rules. The only real difference is the limitation
on status code that may be specified. Only status codes supported by errorfile
directives are supported for this new directive. Parsing of errorfile directive
remains independent from http-error parsing. But functionally, it may be
expressed in terms of http-errors :
errorfile <status> <file> ==> http-errror status <status> errorfile <file>
