ABOUT git-svn-migrate --------------------- The git-svn-migrate project is a set of helper scripts to ease the migration of Subversion repositories to Git. The basic steps to converting a list of Subversion repositories into Git repositories are the following: 1. Create a list of Subversion repositories to convert. 2. Create a list of transformations for Subversion usernames to Git committers. Run: ./fetch-svn-authors.sh --url-file=[filename] > [output file for raw authors] Then edit the raw list of Subversion usernames to provide full names and emails suitable for Git committers. 3. Convert the Subversion repositories into bare Git repositories with: ./git-svn-migrate.sh --url-file=[filename] --authors-file=[filename] [destination folder] A blog post about these migration scripts and a blog post about the underlying techniques are available at: http://john.albin.net/git/git-svn-migrate http://john.albin.net/git/convert-subversion-to-git USAGE ----- 1. Create a list of Subversion repositories to convert. The repository list should just be a plain text file with one repository per line. Each line can be in one of two formats. The basic format is simply the repository's URL by itself: svn+ssh://example.org/svn/awesomeProject file:///svn/secretProject https://example.com/svn/evilProject With this format the name of the project is assumed to be the last part of the URL. So these repositories would be converted into awesomeProject.git, secretProject.git and evilProject.git, respectively. If the project name of your repository is not the last part of the URL, or you wish to have more control over the final name of the Git repository, you can specify the repository list in tab-delimited format with the first field being the name to give the Git repository and the second field being the URL of the Subversion repository: awesomeProject svn+ssh://example.org/svn/awesomeProject/repo evilproject file:///svn/evilProject notthedroidsyourlookingfor https://example.com/svn/secretProject With this format you can use any name for the final Git repo. In the first example above, we're using the second-to-last part of the URL instead of the last part of the URL. In the second example, we're just changing the name to all lowercase (recommended). And in the final example, move along. Move along. 2. Create a list of transformations for Subversion usernames to Git committers. Using the repository list created in step 1, run the fetch-svn-authors.sh script to create a list of unique usernames for all the commits in your repositories. The output of the script should be redirected to a file. Example (assuming your repository list is in "repository-list.txt"): $ ./fetch-svn-authors.sh --url-file=repository-list.txt > author-transform.txt Edit the raw list of Subversion usernames to provide full names and emails suitable for Git committers. The output of the fetch-svn-authors.sh script will be of the form: username = username <username> You should edit each line to be: username = Full name <email> For example: change: jwilkins = jwilkins <jwilkins> into: jwilkins = John Albin Wilkins <firstname.lastname@example.org> You can run "./fetch-svn-authors.sh --help" to get full documentation on the options it accepts. 3. Convert the Subversion repositories into bare Git repositories. Example: $ ./git-svn-migrate.sh --url-file=repository-list.txt --authors-file=author-transform.txt /var/git You can run "./git-svn-migrate.sh --help" to get full documentation on the options it accepts. AUTHENTICATION -------------- Authenticating with each of the repositories is out-of-scope for these scripts. You should ensure that all of the SVN repositories can be accessed non-interactively (i.e. no password prompts) in order for these scripts to work. If you consider this a bug, bugfixes are welcome!
