I'm quite new to git and I'm trying to move a svn repository to git. I followed the guide below so now I have a git repo on my server
http://pauldowman.com/2008/07/26/how-to-convert-from-subversion-to-git/
So, if I do "git branch" git replies "* master" and if I do "git branch -r" i get a list of all the branches in the svn repository.
My last svn-checkins have been in one of the branches, but when I did the "git svn clone"-stuff my commits in that branch (they have not been merged into the trunk yet) are visible in my (git) master branch. What am I missing here?
Also, if I on my development machine do "git clone " I get the files alright. But if I do "git branch -r" I can only see the master branch and not the remote branches".
Since we're getting rid of the svn-repo all together I would like to have all the svn branches in the git-repo so that they can be accessed from the developer clients.
Again, I'm not a total git newbie but not far from it. So if there is something fundamental I'm missing here please tell me.
Update
After doing some RTFM (man git-svn) I solved the first problem with branch stuff present in the master branch
reset --hard remotes/trunk
Now the trunk and the master branch are the same. Now, next is to figure out how to get the branches from the development clients.
Update 2
I got it working by combining the url above and the url that Scott pointed to. So, from the beginning.
I first created an empty repository on the server, they are kept in /usr/local/git-repos on our server:
server> cd /usr/local/git-repos
server> mkdir my_project.git
server> cd my_project.git
server> git init
Then i cloned the svn-repository to my dev-machine (note, that on our svn server the "branches" dir is called "branch" witout the 's'):
dev> git svn clone http://<svn.server>/my_project --no-metadata -A authors.txt -t tags -b branch -T trunk my_project
Then some clean-up to get the tags and branches in order:
dev> cp -Rf .git/refs/remotes/tags/* .git/refs/tags/
dev> rm -Rf .git/refs/remotes/tags
dev> cp -Rf .git/refs/remotes/* .git/refs/heads/
dev> rm -Rf .git/refs/remotes
Now add my server as a remote repository:
dev> git remote add origin jorgen@<our_server>:/usr/local/git-repos/my_project.git
Finally, push all branches and tags up to the server:
dev> git push origin --all
Phew, now there you have it, now I can get rid of that svn-repo.
Update 3
Checkout ebneters post below for an easier way of doing it...
When moving to Git from another version control system like Subversion (SVN), we generally recommend that you perform a "tip migration", which migrates just the latest version of the repository contents, without including history.
git-svn is a specialized tool for Git users to interact with Git repositories. It works by providing a Git frontend to an SVN backend. With git-svn, you use Git commands on the local repository, so it's just like using normal Git. However, behind the scenes, the relevant SVN commands are sent to the server.
There is a fairly detailed explanation on how to do a pretty good SVN import that explains how to convert the branches properly here:
https://git-scm.com/book/en/v1/Git-and-Other-Systems-Migrating-to-Git
The short answer is to run this:
$ cp -Rf .git/refs/remotes/* .git/refs/heads/
$ rm -Rf .git/refs/remotes
Hope that's helpful.
Another good way to do this, just for the record, is to use svn2git — I'm in the middle of converting several rather large repositories and it has been a godsend. It automates all of the steps needed to take care of branches and convert svn tags to real git tags.
Scott's solution didn't work for me. I suspect something may have changed in a recent version of git-svn since he posted that (and since the linked book was written), as it seems to aggressively garbage-collect as soon as the clone is complete. But this is just a guess as to why it didn't work. I'm using git 1.6.5.6.
Specifically, my .git/refs/remotes directory was completely empty except for a tags directory, which was also empty. So there is nothing I can copy to make it right.
After some poking around, I was able to fix this by checking the file .git/packed-refs and doing search-and-replace on the following (in this order):
refs/remotes/tags => refs/tags
refs/remotes => refs/heads
If your editor is vim, you can do it with these two commands:
:%s/refs\/remotes\/tags/refs\/tags/g
:%s/refs\/remotes/refs\/heads/g
svn2git 1.3.1 also did not produce a usable result for me (did not import any commits after a certain point several months ago, and branches all showed the same commits). For now I have given up on svn2git and have had the most success using git-svn combined with the above.
Wishful thinking: sure would be nice if git-svn simply added a command like 'abandon' or 'migrate' that would automate this process in a future-proof way.
