hello list,

I have been using git-svn in an corporate environment where svn repo has lot of 
branches, (lot means > 100). To avoid cloning all branches my config looks as 
below

[svn-remote "svn"]
        url = svn+ssh://url
        fetch = srcroot/trunk:refs/remotes/trunk
        branches = srcroot/branches/{branch_1, branch_2, 
branch_3}:refs/remotes/*

Now, when a new branch of my interest is added in svn repo, I had like it to be 
in my git-repo as well. In an ideal world, one shall simply add that branch 
name to list in curly braces above, but that does not work. I had love to be 
proved wrong here. Somebody on stackoverflow.com suggested (to else's question, 
not mine) to add one more "fetch" as show below.

[svn-remote "svn"]
        url = svn+ssh://url
        fetch = srcroot/trunk:refs/remotes/trunk
        fetch = srcroot/branch_4:refs/remotes/* # NEW BRANCH
        branches = srcroot/branches/{branch_1, branch_2, 
branch_3}:refs/remotes/*

haven't tried it, neither do I like it.

I do have a solution which WORKS, it is modified version of an example from 
\doc\git\html\git-svn.html page. Below I have pasted the example and modified 
it to reflect my specifics.

# assume an existing git-svn repo
        D:\sourcecode
# Clone locally - make sure the refs/remotes/ space matches the server
        mkdir project
        cd project
        git init
        git remote add origin file:///D:/sourcecode # file:// is delibrate, 
want true n/w behaviour
        git config --replace-all remote.origin.fetch 
'+refs/remotes/*:refs/remotes/*'
        git fetch
# Prevent fetch/pull from local git repo,
# we only want to use git svn for form here
       git config --remove-section remote.origin
# Create a local branch from one of the branches just fetched
        git checkout -b master FETCH_HEAD
# Initialize 'git svn' locally (be sure to use the same URL and -T/-b/-t 
options as were used on server)
        git svn init http://svn.example.com/project

# edit config to include newly added branch in curly braces
# Pull the latest changes from Subversion
        git svn fetch -r <recentish rev, say BEGIN>:HEAD

Above works exactly as I want, except the last step of "git-svn fetch" connects 
to svn repo for each revision from BEGIN to HEAD. I want fairly long history 
(for pretty blame). Which implies my BEGIN is not so recentish adterall. Hence, 
it takes awfully long to finish, 2 days typically.

I keep an watch for "svn-remote.svn.branches-maxRev", this serves as my 
progress. This wait is too much for a simple branch. Though, I must point out, 
day feels fresh once it finishes :) Does any one know any for this?

If you paid attention this is Windows machine
git version 1.8.1.msysgit.1


thanks,
Quark
