I was given a branch in an SVN repo to work on. My plan is to merge it with trunk in Git to indicate how much easier it would be to use Git.

Unfortunately, Git doesn't seem to realize that my branch is a branch from SVN's trunk. For example, I have made no changes to file foo.c

The main trunk has changes to foo.c

When I merge, those changes show up as conflicts.

gitk doesn't show any branch points, and I'm thinking that Git just doesn't see the branches as they are in SVN.

The sha-1 of the branch commit from SVN shows up in gitk when I've checked out my branch, but not if I have the trunk checked out (though a git log DOES show it).

Here's what I did to initially set this up (I'm working on $SVNROOT/ branches/FOO):

git-svn init ssh://www.theirrepo.com/svnroot git-checkout -b local-trunk trunk git-branch local-foo FOO git-checkout local-foo

git-svn dcommit on local-foo sends changes to FOO, if on local-trunk, they are sent to trunk in SVN git-svn rebase gets changes from FOO or trunk, as appropriate

Here's my .git/config:

[core]
    repositoryformatversion = 0
    filemode = true
    bare = false
    logallrefupdates = true
[svn-remote "svn"]
    url = svn+ssh://davec@svn.theirrepo.com/svnroot
    fetch = trunk:refs/remotes/trunk
    branches = branches/*:refs/remotes/*
    tags = tags/*:refs/remotes/tags/*

Any ideas?

How much history did you fetch from subversion? If you didn't fetch at least to the branch point, then that could explain what you're seeing. If the SVN repository isn't too large, it is probably worth the time to fetch the entire history (from r1 forward).

That's expected; it sounds like you want "gitk --all"

Re: Getting git-svn to recognize branchpoints?

OK, gitk is now showing it using the --all.

I did get the entire history. It seems like when I merge, every file that was changed on trunk since the branch shows up as a conflict, including files that I have not changed on my branch.

For one particular file, the history is:

6/4/07 - File Created 8/9/07 - File modified 12/3/07 - File modified 4/24/08 - Branch created

The diffs of the conflict make no sense, e.g.

<< From Trunk some_stuff(); that_was_added(); ====

>> From My Branch

I've tried all the merge strategies, and nothing makes a difference...
