We see issues in ovsdb plugin also now.
If functionalities are broken due to the patch, it is taking a lot of time for 
us also to debug and figure out where and all it is causing breakages.

Thanks,
Faseela

FYI I just opened a grievance to remind what we did today is exceptional and to 
be avoided in future:

https://jira.opendaylight.org/browse/TSC-92

I've commented in TSC-92 arguing that I'm struggling to understand how "it 
stands, and pointed by Tom, backing out the change looks to be a daunting task"…

Please ask Tom P and Robert, both said during TSC call it was lot of work to 
revert, in addition nobody except Anil saw any problem wth the patch so that 
was the other reason it went through.

Robert & Tom,

Regardless of the merits of this particular change, I agree with Vishal & Luis 
that this is a failure of communication. The weather process needed to have 
been followed - with the possibility for downstream projects to not accept the 
change for legitimate reasons. Please do so in the future.

The most ideal solution as suggested by Luis below & initially agreed by Tom 
would have been to back out the change, discuss it completely (in a the TWS 
call) and go ahead with the decision after the TWS call. As it stands, and 
pointed by Tom, backing out the change looks to be a daunting task. Since that 
is the case, let us do the following:
0) Unblock the projects by whatever means - whether it is projects merging the 
changes to accommodate the original patch or reverting
1) Robert, please create the weather report with the existing change
2)  in the meantime people can chime in on the thread and try to resolve it
3) we WILL continue the discussion on the Monday TWS if this is not resolved by 
Monday. Casey has this meeting scheduled in any case.

Thanks,
Abhijit

Hi Robert,

Could you please take a look at tell what I need to fix this breakage? I am 
still not sure why is such a basic code breaking like this.


Perhaps we should just revert the mdsal patch until this can get sorted out 
downstream - maybe discuss on the TSC call today .

+1, without knowing the technical details of the change, I think we are missing 
something fundamental in the upstream-downstream communication: in general for 
any valid change coming from upstream breaking downstream we need a weather 
report including explanation why the change is required and some pointers on 
how to fix the potential failures. This gives a chance for downstream projects 
to evaluate and accept the change as well as to prepare the required patches to 
minimize the impact. If the breakage was unintentional or unexpected (no 
weather fired), I think the right thing to do is to revert and start over 
writing the weather report.




Regards,
Vishal.
