At present option smtpchk closes the TCP connection abruptly on completion of service checking,
even if successful. This can result in a very high volume of errors in backend SMTP server logs.
This patch ensures an SMTP QUIT is sent and a positive 2xx response is received from the SMTP
server prior to disconnection.
This patch depends on the following one:
* MINOR: smtpchk: Update expect rule to fully match replies to EHLO commands
This patch should fix the issue #1812. It may be backported as far as 2.2
with the commit above On the 2.2, proxy_parse_smtpchk_opt() function is
located in src/check.c
[cf: I updated reg-tests script accordingly]
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.
Its sole remaining purpose was to display "proxy foo started", which
has little benefit and pollutes output for those with plenty of proxies.
Let's remove it now.
The VTCs were updated to reflect this, because many of them had explicit
counts of dropped lines to match this message.
This is tagged as MEDIUM because some users may be surprized by the
loss of this quite old message.
