     In the fixes commit below, ct_commit was changed to use nested actions.
     This requires that curly braces be present for all ct_commits. When
     adjusting ovn-northd, some ct_commits were not updated to have them.
     This commit changes the behavior of the ct_commit action not to require
     curly braces if there are no nested actions required.

Thanks for the fix.

The system test case - 29: ovn --Test packet drops due to incorrect
flows in physical table 33 FAILED (system-ovn.at:4538
<http://system-ovn.at:4538>) is failing
on my setup. But this patch is not the issue. I see failure with the
master too. Just FYI.

OK. Just to throw out another data point, that test passes on my setup.


It's a timing issue and adding the below before the check fixes the
issue for me and tests passes all the
time when I run in a loop.

OVS_WAIT_UNTIL([test x$(ovn-nbctl lsp-get-up sw0-p1-f) = xup])
OVS_WAIT_UNTIL([test x$(ovn-nbctl lsp-get-up sw0-p2-f) = xup])
OVS_WAIT_UNTIL([test x$(ovn-nbctl lsp-get-up sw0-p3-f) = xup])

I'll submit the patch to fix it later.

Thanks
Numan

OK, cool.

In the meantime, I pushed this patch to master.





Thanks
Numan
