Subject: git-svn too slow, contacts upstream svn repo
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
