Here's from my notes on how I'm supposed to merge the Gnorb package into
ELPA. I started using git subtree because it seemed conceptually like
the right thing. It turned out to be pretty complicated (because I
didn't understand it well) and I still feel a sense of dread every time
I go to update the package. I wish there were a simpler way.
I added a local git repo as a remote ("gnorb") to the elpa repo. Pulling
from the external repo goes:
git fetch gnorb
git subtree pull --squash --prefix=packages/gnorb gnorb master
Pushing from the ELPA repo to the gnorb remote (I tried this because
Stefan made some changes directly in the packages):
git subtree push --squash --prefix=packages/gnorb gnorb master
This is followed by an expletive-filled paragraph of notes. I'm not sure
pushing to the remote ever actually worked. I also tried something
called "split branch", which barfed several pages of output into my
shell, to what end I'm still not sure.
In the end, when I wanted to get changes from ELPA into my external
repo, I think it worked okay to simply throw a patch over and apply it
there. There's no actual correspondence between commit SHAs in ELPA and
the remote, so simply having the files in the same state is good enough.
But basically it felt like I was going to have to learn all of the
internals of git to do this with any sort of confidence.
