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.
iif() takes a boolean as input and returns one of the two argument
strings depending on whether the boolean is true.
This converter most likely is most useful to return the proper scheme
depending on the value returned by the `ssl_fc` fetch, e.g. for use within
the `x-forwarded-proto` request header.
However it can also be useful for use within a template that is sent to
the client using `http-request return` with a `lf-file`. It allows the
administrator to implement a simple condition, without needing to prefill
variables within the regular configuration using `http-request
set-var(req.foo)`.
