Subject Re: [DISCUSS] Freezing master for 4.11
Date Fri, 12 Jan 2018 17:57:48 GMT

We're down to one feature PR towards 4.11 milestone now:

The config drive PR from Frank (Nuage) has been accepted today after no regression test failures
seen from yesterday's smoketest run. We've also tested, reviewed and merge Wido's (blocker
fix) PR.

I've asked Mike to stabilize the branch; based on the smoketest results from today we can
see some failures caused by the PR. I'm willing to work with Mike and others to get this PR
tested, and merged over the weekends if we can demonstrate that no regression is caused by
it, i.e. no new smoketest regressions. I'll also try to fix regression and test failures over
the weekend.

Lastly, I would like to discuss a mistake I made today with merging the following PR which
per our guideline lacks one code review lgtm/approval:

The changes in above (merged) PR are all localized to a xenserver-swift file, that is not
tested by Travis or Trillian, since no new regression failures were seen I accepted and merge
it on that discretion. The PR was originally on the 4.11 milestone, however, due to it lacking
a JIRA id and no response from the author it was only recently removed from the milestone.

Please advise if I need to revert this, or we can review/lgtm it post-merge? I'll also ping
on the above PR.

- Rohit

No, it doesn't. IPv6 was introduced in 4.10 and this broke in 4.10.

You can't run with 4.10 with multiple IPv4 CIDRs as well when you have
IPv6 enabled.

So this is broken in 4.10 and 4.11 in that case.
