Establish a mirror between existent SVN project and new Git repository.

A SVN project mirroring using SubGit in Linux/MacOS step-by-step guide.


  1. Install Java Runtime environment and SubGit binaries using installation guide.
     

  2. Configure repository

    • Run this command on behalf of the same user you use to serve Git repository

      subgit configure
      $ subgit-3.2.4/bin/subgit configure --layout auto --trunk trunk SVN_URL GIT_REPO

      where

          SVN_URL - SVN project URL.
          GIT_REPO - path to new Git repository

      subgit configure example
      $ subgit-3.2.4/bin/subgit configure --layout auto --trunk trunk http://example.com/svn/repository/project ./repo.git

            SubGit version 3.2.4 ('Bobique') build #3670

            Configuring writable Git mirror of remote Subversion repository:
                Subversion repository URL : http://example.com/svn/repository/project
                Git repository location   : ./repo.git

            Detecting peg location... 
            Authentication realm: <http://example.com:80> Subversion Repository
            Username [user]: user
            Password [user]:
            Peg location detected: r10248 project/trunk
            Fetching SVN history... Done.
            Growing trees... Done.
            Project origin detected: r1 project/trunk
            Building branches layouts... Done.
            Combing beards... Done.
            Generating SVN to Git mapping... Done.

            CONFIGURATION SUCCESSFUL

            To complete SubGit installation do the following:

            1) Adjust Subversion to Git branches mapping if necessary:
                /home/user/repo.git/subgit/config
            2) Define at least one Subversion credentials in default SubGit passwd file at:
                /home/user/repo.git/subgit/passwd
               OR configure SSH or SSL credentials in the [auth] section of:
                /home/user/repo.git/subgit/config
            3) Optionally, add custom authors mapping to the authors.txt file(s) at:
                /home/user/repo.git/subgit/authors.txt
            4) Run SubGit 'install' command:
                subgit install ./repo.git

    • Set authors mapping
      Update GIT_REPOS/subgit/authors.txt file or change core.authors option to point to global authors mapping. 

      There are several methods to configure authentication to access SVN server, but we use plain text password file here to simplify the guide. If this method does not fit your needs please check Test Page authentication guide for a more appropriate method.

    • Specify an username and password to be used by SubGit in `GIT_REPO/subgit/passwd` file. By default, there's the 'subgitsecret' credential pair in the file; replace it by 'user password' pair to be used to access SVN server by SubGit. 


       
  3. Perform SubGit installation and start using new Git repository: 
     

    • Install SubGit into the repository by the command:

      subgit install
      $ subgit-3.2.4/bin/subgit install GIT_REPO
      subgit install example
      $ # subgit install /home/user/repo.git

            SubGit version 3.2.4 ('Bobique') build #3670

            Translating Subversion revisions to Git commits...

            Subversion revisions translated: 10248.
            Total time: 2 hours 15 minutes 23 seconds.

            INSTALLATION SUCCESSFUL

            Your copy of SubGit is not registered for repository at '/home/user/repo.git'.

            Obtain registration key at http://www.subgit.com/ and register SubGit with 'register' command;
            registration is free for Open Source, Educational and Startup projects.

            To uninstall SubGit use 'uninstall' command.

    • When the command completes, you can clone your new Git repository and start to work with it:

      git clone
      $ git clone GIT_REPO WORK_TREE

      where 

      WORK_TREE - a path to your working copy.

      git clone example
      $ git clone file:///home/user/repo.git/ /home/user/repo_working_copy/
                Cloning into '/home/user/repo_working_copy'...
                remote: Counting objects: 99, done.
                remote: Compressing objects: 100% (89/89), done.
                remote: Total 99 (delta 51), reused 0 (delta 0)
                Receiving objects: 100% (99/99), 8.96 KiB | 0 bytes/s, done.
                Resolving deltas: 100% (51/51), done.
