Correct.
There is a single "v2.x" branch that was branched from master a while ago (I
didn't check, but I assume the hash Gilles cites below is correct). v2.0.0 is
tagged on that branch.
Git branches and v2.0.x and v2.x plans were a topic we discussed in the
face-to-face meeting in Dallas last week. Here's a summary...
Soon, we will be doing the following:
- release v2.0.1 from the v2.x branch and tag it in git
- merge in v2.0.2 PRs (which should all be low risk)
- merge in low risk v2.1.0 PRs that do not have conflicts (some are quite old)
- freeze the ompi-release repo
- remove everyone's write permissions
- ask PR authors to re-create their PRs on the ompi repo
- merge all the branches in ompi-release back in to ompi
- (possibly) "git rm -rf" everything in all ompi-release branches, and
leave a single README.md saying "Everything is in the ompi repo now"
--> Sidenote: when we moved to Github, we initially created the ompi and
ompi-release repos because Github did not originally support per-branch ACLs.
Now they do, so once we hit a natural development break point (i.e., after
v2.0.1), we can finally merge ompi-release back into ompi and work solely out
of a single git repo. Yay!
(...at this point, the v2.x branch will be in ompi...)
- create branch v2.0.x from v2.x
- update VERSION on v2.0.x to be v2.0.2a1
- update VERSION on v2.x to be v2.1.0a1
Does that make sense?
