Subject asf/vpc branch merge
Date Fri, 10 Aug 2012 17:33:53 GMT

Considering that there is a code freeze happening soon, and as the main
part for VPC feature development is complete + the VPC code
has been well tested by cloudStack QA engineers, it's time to discuss
merging the asf/vpc branch into asf/master. At this point its too hard to
break it to several components-to-merge as there were too many single
commits for the last couple of months from 7 developers involved in the
process + we were doing the daily merges with master branch in order to
keep asf/vpc branch up to date. It makes it hard to componentize at this
point without running into lots of rebase conflicts

So most likely it will be done as a single merge if
the merge gets approved by the community. We would highly
appreciate any help involving code/documentation review as well as any
other suggestions on how to make this particular merge safer and smoother.
And the suggestions made towards the merge process in general, will all be
addressed in the future.

We've tried to keep vpc branch in sync with asf/master by performing daily
merges from master branch to vpc, so there shouldn't be too many
conflicts. The VPC code went through several rounds of QA including the
regression testing for existing network components. Most of the VPC code
resides in the new classes added as a part of the feature; but some
existing Network related code got some changes and can be considered for
the review (NetworkManagerImpl/VirtualNetworkApplianceManager in
particular as well as some Agent APIs and cloudStack UI). The VPC FS
contains the reference to new classes (including client/agent APIs)
created for the VPC feature (see the link below).

I'm well aware the 4.0 will be branched on Monday, so once the merge is
approved, I can do the merge over the weekend including doing basic
regression for the networking key components on the merged branch.
