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.
if the monitor-uri starts by a slash ('/'), the matching is performed against
the request's path instead of the request's uri. It is a workaround to let the
HTTP/2 requests match the monitor-uri. Indeed, in HTTP/2, clients are encouraged
to send absolute URIs only.
This patch is not tagged as a bug, because the previous behavior matched exactly
what the doc describes. But it may surprise that HTTP/2 requests don't match the
monitor-uri.
This patch may be backported to 2.1 because URIs of HTTP/2 are stored using the
absolute-form starting this version. For previous versions, this patch will only
helps explicitely absolute HTTP/1 requests (and only the HTX part because on the
legacy HTTP, all the URI is matched).
It should fix the issue #509.
