When threads are enabled and running on a machine with multiple CCX
or multiple nodes, thread groups are now enabled since 3.3-dev2, causing
load-balancing algorithms to randomly fail due to incoming connections
spreading over multiple groups and using different load balancing indexes.
Let's just force "thread-groups 1" into all configs when threads are
enabled to avoid this.
-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.
No less than 30 tests were missing timeouts, preventing them from being
started with zero-warning. Since they were not supposed to trigger, they
have been set to 30s so as never to trigger, and now they do not produce
any warning anymore.
We don't have enough tests with the mworker mode, and even less that
have no master CLI (-S) configured. Let's run this one with -W, it
shouldn't have any impact.
VTest won't be able to catch a lot of things for now, but that's a first
step.
