[petsc-users] [petsc-dev] petsc git next branch *is* unwound!

What is meant by the phrase "petsc git next branch is unwound"?  What git
commands are run to do this?  And how is the next branch different when
it is unwound from immediately before it is unwound?

Thanks,

Dave

On my local machine I have my master, bare git repo with the following config file
which Jed suggested a year or so ago:

% cat config
[core]
        repositoryformatversion = 0
        filemode = true
        bare = true
        sharedrepository = 1
[receive]
        denyNonFastforwards = true
[remote "origin"]
        url = https://bitbucket.org/petsc/petsc
        fetch = +refs/heads/maint:refs/heads/maint
        fetch = +refs/heads/master:refs/heads/master
        fetch = +refs/heads/next:refs/heads/next
[remote "artab"]
        url = ssh://ml-fey.lanl.gov/usr/projects/artab/users/wdn/repos/git/petsc
        fetch = +refs/*:refs/*
        mirror = true

And for my workflow, I stay in sync with the official PETSc git repo by periodically
executing the following command:

git remote -v update origin

And then I have various git clones from my master git repo where I do actual
work.

Do I need to do anything special now that the "next" branch has been unwound
with either my master git repo or my git clones?  In my master git repo, I have
3 additional branches - wdn_mods_next, wdn_mods_master and wdn_mods_maint
where I keep any of my own modifications to those respective branches.  And I
keep wdn_mods_next in sync with next by periodically executing the following
commands in a git clone with the wdn_mods_next branch checked out:

git pull origin next

resolve any conflicts and commit

git push origin wdn_mods_next:wdn_mods_next

So, if I do the following set of steps, should I expect them to work now that next
has been unwound?

1. cd to my master bare petsc repo
    git remote -v update origin

2. cd to my git clone of petsc with wdn_mods_next branch checked out
    git pull origin next
    resolve any conflicts and commit
    git push origin wdn_mods_next:wdn_mods_next

Thanks,

Dave

BTW: Some of you might want to rebase/cleanup some of the feature branches
before merging to new next.

Also some of these feature branches are from pre-petsc-3.5 timeframe.
So a rebase to latest master might be something to consider. [if they
are still in line for a merge to master]
