git-svn multiple branches and merging

[Igor Lautar <igor.lautar@gmail.com>]

Hi All,

I'm using git-svn to manage quite large svn repository. This
repository also does not follow 'general' svn rules about how to name
branches.

So we have something like:
trunk -> development
branches\version1 -> version1 maintenance
branches\custom\version1_fix -> customized version1 with certain fixes

etc.

When importing, I've only imported trunk and branches I'm interested
in. Thus, I have multiple remotes for which git-svn does not know they
are related (or how they branched from each other). Also, I have not
imported whole history, as its just to much trouble.

Now, I want to start a new branch, lets say branches\dev1, which is
branches from trunk. This will be used for various improvements, which
do not go to trunk immediatelly.
I also want to keep this branch in sync with main trunk.

Up to now, I have been doing this by git-cherry-pick all changes from
dev1 branch point. Is there a better way to do? Note that branch dev1
in git-svn does not know about previous commits in trunk (git remote
ref was initialized from branch point for dev1).

Just merging trunk (represented by a remote in git-svn) makes a mess
(as expected). Basically, what I want to do is tell git-svn that merge
was already done up to a certain point from that branch so git-merge
then only picks up new changes from that point on (and the ones that
have not been cherry-picked).

Is there a way to get out of this mess? I'm fine with cherry-pick, but
it requires some manual labor (like remembering/finding last
cherry-picked commit).

Thank you,
Igor
