Migrating to Git
(Updated: Dec 2009)
To migrate ongoing work from CVS to git SCM, first convert your work to a patch, then apply that patch to a git tree.
Convert your work to patches
Work that does NOT live in a private CVS branch
If you maintain your development code with quilt or something else other than a CVS private branch, generate patches for any current work.
cvs diff > my.patch
Work from a private CVS branch
1. In your branch CVS working tree, use 'cvs diff' against the base tree divergence point. Since you've been using the build/merge scripts, this is quite easy. For example, params tree branch:
cvs diff -r HD_PARAMS_TREE_BASE > hd_params_tree.patch
The merge scripts have kept the <branchname>_BASE tag updated to reflect the latest merge (don't use an old dated tag, use the one ending in _BASE).
This cvs diff will include uncommitted changes in your working tree as well as all your committed code, so make sure your working directory tree is in the state you want.
2. Inspect your patch to make sure it is correct. It will be a patch against the divergence point, so realize that the base branch may have moved on and your patch may have to be updated when you apply it.
Apply your patches to a git repo
Obtain a clone of the Accessing Lustre Code.
git clone --origin prime email@example.com:prime/lustre <mydir> cd <mydir>
Create your own private branch. For example, a branch for bug 20000 based off of HEAD:
git checkout -b bug20000 master
Apply the patch to that branch
patch -p1 < hd_params_tree.patch
Resolve any merge conflicts, and commit the patch (to your branch)
git commit -a -v
Sun employees should continue development under git as per the Lustre GIT page.
External contributors should follow the procedure for submitting patches.
