[PATCH] gitlab: Disable io-raw-194 for build-tcg-disabled
Posted by Richard Henderson 11 months ago 
This test consistently fails on Azure cloud build hosts in
a way that suggests a timing problem in the test itself:

There is actually a bug in the test, I've sent a patch:

The line of output that has changed was originally added by the
following commit:

commit ae00aa2398476824f0eca80461da215e7cdc1c3b
Author: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>

    iotests: 194: test also migration of dirty bitmap

Vladimir: Any idea why the postcopy-active event may not be emitted in
some cases?

I think:

fast connection + small postcopy data => postcopy actually not started, everything is migrated in downtime, when both source and target are not running.

The test doesn't want to test exactly postcopy, but just want to check that bitmaps are migrated somehow.


So, we need something like this:

diff --git a/tests/qemu-iotests/194 b/tests/qemu-iotests/194
index 68894371f5..c0ce82dd25 100755
--- a/tests/qemu-iotests/194
+++ b/tests/qemu-iotests/194
@@ -74,6 +74,11 @@ with iotests.FilePath('source.img') as source_img_path, \
  
      while True:
          event1 = source_vm.event_wait('MIGRATION')
+        if event1['data']['status'] == 'postcopy-active':
+            # This event is racy, it depends do we really do postcopy or bitmap
+            # was migrated during downtime (and no data to migrate in postcopy

+            continue
          iotests.log(event1, filters=[iotests.filter_qmp_event])
          if event1['data']['status'] in ('completed', 'failed'):
              iotests.log('Gracefully ending the `drive-mirror` job on source...')

Is it useful to modify 194.out.bad ...

This is not a patch, it's the testsuite output.

That's fair to remove it: The iotests that are run here were only added here 
because they were tested to succeed on the shared runners - if they were 
running successfull everywhere, we would have added them to the "auto" group 
instead so that they'd run during "make check-block". So if something is 
failing on the private runners now, it's ok to remove them from this list here.
