sub module branches

Hi

I have a situation like

project/source.git
           /submod_1
           /submod_2

I need to modify code in all 3 repos viz. source, submod_1 & submod_2.

If I create branch in source, will it propogate to remaining
submodules ? or in other words can I have "global branch" and "global
tag"

Thx/

Mahesh.

No, the branch is only created in the top-level module.

The branch is "global" in the way that it does contain a reference to the 
current commit of the submodule. You do not *need* to have a local branch 
in the submodule to change where it pointed to from the top-level module. It 
does help to have it, though, as you eventually probably will want to push 
your changes somewhere, and then you need to have a symbolic reference in 
the submodule(s) you have branched as well.

You could use git-subtree instead: http://github.com/apenwarr/git-subtree

That will allow you to branch all the repos at once.  It slightly
increases the effort required to extract the changes and submit them
upstream again, though.

Have fun,
