my case is as follows
I have two branches
basically they are the same, except they differ from different package
name(java) and namespace(cpp) due to customer request

but now I have a fix , say a patch
I want to commit it to both branches

but I am lazy so I just want to do just one 'git commit' and 'git
push'

so I am thinking using a githook in remote server
and each commit to branch A can also commit to branch B as well

but I am not quite sure what I should use in the hook

git rebase , git merge or git cherry pick ?

seems these 3 ways all lead to the same result
but I dont know which is better and why

if by "patch" you mean git-am/git-apply then I'm afraid i don't have any suggestions because i don't use those commands. However, if you use git-push then have you thought about having a script on the local side that does something like this:

$ git checkout java-branch
(hack hack)
$ git add .
$ git commit
$ bash -v myscript  <--run your script
#!/bin/sh
# script to commit java-branch head to cpp-branch and push them both
git checkout cpp-branch &&
wait
git cherry-pick java-branch &&
wait
git push origin HEAD &&
wait
git checkout java-branch &&
wait
git push origin HEAD &&
wait
exit 0

of course, you need some error checking in there. this is predicated on the assumption that the cherry-pick will not get any conflicts. if it does get conflicts then you will have to resolve them manually and that is a big reason to do this on the local side instead of the remote side.

v/r,
