  • This line was added.
  • This line was removed.
  • Formatting was changed.
  1. Install SubGit tool according to the Installation guide.

  2. Configure GitLab server:

    • Login Log in to GitLab web GUI and create a new project:



      Give a name to your project, do not check “Initialize repository with a README” checkbox, and click Create project button.

  3. Configure the repository:

    • Change identity to 'git' user:

      Code Block
      languagetext
      themeFadeToGrey
      titlechange identity to git user
      $ su git


    • Change the directory to that the one that contains the newly created project.

      • Older versions of GitLab stored projects in

        No Format
        /var/opt/gitlab/git-data/repositories/<username>

        where <username> was the GitLab username that had been used during the project creation on step 1.

      • Since version 10.0 GitLab uses hashed storage as follows:

        No Format
        /var/opt/gitlab/git-data/repositories/@hashed/<hash[0..1]>/<hash[2..3]>/<hash>.git


        Note

        To find the repository path in GitLab v.10+, follow this guide. 


    • Navigate to that directory:

      Code Block
      languagetext
      themeFadeToGrey
      titlechange directory
      $ cd /var/opt/gitlab/git-data/repositories/<repo_path>


    • Perform initial configuration:

      No Format
      $ subgit configure --layout auto --trunk TRUNK SVN_URL GIT_REPO

      where

      • SVN_URL   – SVN project URL.
      • GIT_REPO  – a path to the new GitLab project that's been created at step 1, for example, project.git.
      • TRUNK     – a path, relative to SVN_URL, that leads to an SVN directory that plays a the role of the main line of development.

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

            Git repository is served by GitLab, hooks will be installed into 'custom_hooks' directory.

            CONFIGURATION SUCCESSFUL

            To complete SubGit installation do the following:

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



    • Specify authors mapping.

      Configure authors mapping in default authors mapping file:

      No Format
      GIT_REPO/subgit/authors.txt


      Or change core.authors option so that it points to the global authors mapping file.
      Find more details about authors mapping in in the Authors mapping article.


    • Specify a username and password that are used by SubGit to access the SCN repository. Edit passwd file:

      No Format
      GIT_REPO/subgit/passwd

      By default, there's only subgit secret credential pair. Replace it with with the username and its corresponding password.

      Info
      titleSVN authentication

      There are several methods to configure authentication to access the SVN server, but we use a plain text password file here to simplify the guide. See more authentication methods in SVN Authentication if this method does not fit your needs.


  4. Establish a mirror and start using the new Git repository:

    • Establish a two-way mirror by the with this command:

      No Format
      $ subgit install GIT_REPO

      where 

          GIT_REPO – a path to the GitLab project.

      Expand
      titleSee SubGit install example…


      Code Block
      languagetext
      themeFadeToGrey
      titlesubgit install
      $ subgit install ./project.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 24 seconds.

  INSTALLATION SUCCESSFUL




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

      No Format
      $ git clone GIT_REPO WORK_TREE

      where

          WORK_TREE – a path to your working copy. 


      Expand
      titleSee the command example

      languagetext

      $ git clone http://user@example.com/user/project.git /home/user/gitlab_project.git
  Cloning into '/home/user/gitlab_project.git'...
  Password for 'http://user@example.com':

  remote: Total 99 (delta 50), reused 99 (delta 50)
  Unpacking objects: 100% (99/99), done.



      Warning
      titleEmpty working tree case

      If Git warns you that you are cloning an empty repository and you don't see your files in the working tree, most probably automatic branches and tags mapping didn't work correctly. In this case, mapping has to be set manually, see details on mapping in Branches and tags mapping.


  5. Try and buy.

    Info
    titleTrial period

    Note: the trial period for SubGit mirror is 30 days, after that period you should buy a license key at https://subgit.com/pricing.
