Ben Kallus also noticed that we preserve leading zeroes on content-length
values. While this is totally valid, it would be safer to at least trim
them before passing the value, because a bogus server written to parse
using "strtol(value, NULL, 0)" could inadvertently take a leading zero
as a prefix for an octal value. While there is not much that can be done
to protect such servers in general (e.g. lack of check for overflows etc),
at least it's quite cheap to make sure the transmitted value is normalized
and not taken for an octal one.
This is not really a bug, rather a missed opportunity to sanitize the
input, but is marked as a bug so that we don't forget to backport it to
stable branches.
A combined regtest was added to h1or2_to_h1c which already validates
end-to-end syntax consistency on aggregate headers.
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.
A TCP/HTTP action can stop the rules evaluation. However, it should be
applied on the current section only. For instance, for http-requests rules,
an "allow" on a frontend must stop evaluation of rules defined in this
frontend. But the backend rules, if any, must still be evaluated.
For http-response rulesets, according the configuration manual, the same
must be true. Only "allow" action is concerned. However, since the
beginning, this action stops evaluation of all remaining rules, not only
those of the current section.
This patch may be backported to all supported versions. But it is not so
critical because the bug exists since a while. I doubt it will break any
existing configuration because the current behavior is
counterintuitive.
First, concat() is a converter, not a sample fetch. So use str() sample fetch
with no string and call concat on it. Then, the argument of the set-uri rule
must be a log format string. So it must be inside %[] to be evaluated.
