-Ws on VTest is not working correctly for an unknown reason, the polling
of the NOTIFY_SOCKET seems to timeout, and VTest never receives the
READY message.
This patch disables the reg-tests using -Ws on OS X.
The -W mode implemented in VTest is not reliable anymore, because VTest
waits for the pidfile to be created. But with the new master-worker
mode, this file is created long before haproxy is ready. This can lead
to the test being started too soon, and failing from time to time.
The -Ws option allows to wait for haproxy to deliver a message to VTest
once it is ready.
Every reg-test now runs without any warning, so let's acivate -dW by
default so the new ones will inheritate the option.
This patch reverts 9d511b3c ("REGTESTS: enable -dW on almost all tests
to fail on warnings") and adds -dW in the default HAPROXY_ARGS of
scripts/run-regtests.sh instead.
Now that warnings were almost all removed, let's enable zero-warning
via -dW. All tests were adjusted, but two:
- mcli/mcli_start_progs.vtc:
the programs section currently cannot be silenced
- stats/stats-file.vtc:
the warning comes from the stats file itself on comment lines.
All other ones are now OK.
When vtest starts haproxy process, it loops until the moment, when haproxy
pidfile is created. When pidfile is created, vtest considers that haproxy
process is ready and it starts to perform test commands, in particular, it
connects to CLI. It's not very reliable approach to base the check of the
process readiness on the PID file. After master-worker architecture
refactoring pidfile is created in the early init stage, but master and worker
are not yet finished its initialization routines. So, all mcli tests and some
tests where we sent commands to CLI start to fail regularly.
In vtest at the moment there is no any other approach to check that the
process is really ready. So let's add a delay 0.1s before connecting to CLI in
all mcli tests and in acl_cli_spaces test.
A recent fix broke the pipelined command on the master CLI, this
reg-tests implement a simple test that allow to check its right
behavior.
This could be backported as far as 2.6.
