Converting Assembla SVN repositor to GIT

Converting Assembla SVN repositor to GIT

Move a  subversion repository,  hosted at Assembla to  GIT ,  For this,  we expect that you already have a GIT server and repository setup with permission for you to write to it. there is an error to make sure it is 100% clean)

  • first create 4 directories
    • /data/code/svndump – to download your subversion repositories into
    • /data/code/tmpsvn – to load your temporary subversion repository into after downloading
    • /data/code/tmpgit1  – to create a temp git repository from your svn repo
    • /data/code/tmpgit2  – to create a bare reformatted git repository from your first git
  •  first open the project / repo in assembla
  • Click Import / Export > Download Dump
  • right click on the link and copy link then open command line on a machine with svn and git

 

  • cd /data/code wget -O svndump/myrepo.gz “https://linkcopoiedfromassempla# download the file with quotes (to escape ampersands
  • svnadmin create tmpsvn/myrepo #create an empt repositorycd
  • gunzip -c svndump/myrepo.gz | svnadmin load tmpsvn/myrepo
  • svn log -q file://data/code/tmpsvn/myrepo | awk -F ‘|’ ‘/^r/ {sub(“^ “, “”, $2); sub(” $”, “”, $2); print $2″ = “$2” <“$2″>”}’ | sort -u > users.txt
  • git svn clone file:///data/code/tmpsvn/myrepo/  –no-metadata -A users.txt –stdlayout tmpgit1/myrepo
  • cd tmpgit1/myrepo
  • touch .gitignore #if I dont have any ignore files
  • git svn show-ignore > .gitignore  #if I do have ignore files i svn,  this will return an error if there are no ignore files
  • git add .gitignore
  • git commit -m ‘Converting Properties from SVN  to GIT’ .gitignore
  • cd /data/code
  • mkdir tmpgit2/myrepo
  • cd tmpgit2/myrepo
  • git init –bare
  • git symbolic-ref HEAD refs/heads/trunk
  • Go back to the tmpgit1 repo and push it to the new bare repo and rename the ‘trunk’ to ‘master’
  • cd ../../tmpgit1/myrepo
  • git remote add bare /data/code/tmpgit2/myrepo
  • git config remote.bare.push ‘refs/remotes/*:refs/heads/*’
  • git push bare
  • cd /data/code/tmpgit2/myrepo
  • git branch -m trunk  master
  • Clean up branches and tags (thanks to http://john.albin.net/git/convert-subversion-to-git for most of this)
  • git for-each-ref –format=’%(refname)’ refs/heads/tags |
    cut -d / -f 4 |
    while read ref
    do
      git tag “$ref” “refs/heads/tags/$ref”;
      git branch -D “tags/$ref”;
    done

Now you have a correctly formatted repo at /data/code/tmpgit2/myrepo    you can push it to your final git repository

  • git remote add origin <your final git repository url >
  • git push origin master

This may take a bit of time depending on how much code you have.  But once it is complete you can browse your repository in stash.
