h2. General information

Redmine natively supports integration with different SCM-tools: "Subversion":http://subversion.tigris.org/, "CVS":http://www.nongnu.org/cvs/, "Mercurial":http://www.selenic.com/mercurial/, "Darcs":http://darcs.net/, "Git":http://git-scm.com, and "Bazaar":http://bazaar-vcs.org/.

Note that you need to install the appropriate binaries on your Redmine host and make sure that these binaries are available in the @PATH@ environment variable:

|*SCM*|*Tested with*|*Comments*|

|Subversion|1.3 & 1.4 & 1.5 & 1.6|1.3 or higher required|

|CVS|1.12.12|1.12 required, won't work with CVSNT|

|Mercurial|0.9.3| |

|Bazaar|1.0.0.candidate.1 & 2.0.4| |

|Darcs|1.0.7||

|Git|1.5.4.2||

For example, if you want to access Subversion repositories in Redmine, you'll have to install the svn binaries on the Redmine host. Redmine currently doesn't make use of the Ruby Bindings for Subversion.

Additionally, be sure to enable any SCM you wish to use globally: @Administration->Settings->Repositories->Enabled SCM@

h2. Attaching an existing repository to a project

In the project settings, make sure that the 'Repository' module is enabled and go to the 'Repository' tab.

Select the SCM that corresponds to your repository and enter the path or URL of your repository.

*Important*: When you first browse the repository, Redmine retrieves the description of all of the existing commits and stores them in the database.

This is done only once per repository but can take a very long time (or even time out) if your repository has hundreds of commits.

To avoid this, you can do it offline.

After having your repository declared in Redmine, run the following command:

<pre>

$ ruby script/runner "Repository.fetch_changesets" -e production

</pre>

All commits will be retrieved in to the Redmine database.

Since Redmdine 0.9.x, you can use a link to execute fetch_changesets for a specific project, or all.

http://redmine.example.com/sys/fetch_changesets (=> fetches changesets for all active projects)

http://redmine.example.com/sys/fetch_changesets?id=foo (=> fetches changesets for project foo only)

h3. Subversion repository

The usual protocols are supported (eg. @http:@, @svn:@, @file:@), just enter the URL of the repository.

For example:

<pre>

http://host/path/to/the/repository

</pre>

You can specify a username and password if the repository requires authentication.

Note: if you want to access the repository using @svn+ssh://@, you'll have to configure svn+ssh to be non-interactive.

This requires you to setup a public/private key pair for ssh authentication.

h3. CVS repository

Enter:

* the URL of the repository (it can be either a path or a connection string, eg. @:pserver@).

* the module name

For example:

<pre>

:pserver:login:password@host:/path/to/the/repository

</pre>

h3. Git repository

h4. Local environment setup

Redmine requires a *bare* and *local* repository to enable browsing through Redmine.

Imagine you want to browse the to-do list manager project "Donebox": its clone URL is @git://github.com/ook/donebox.git@.

On the server where you're running Redmine, create a directory accessible by the user running your Redmine server:

<pre>

$ sudo mkdir -p /var/redmine/git_repositories

$ sudo chown rails:rails /var/redmine/git_repositories

$ cd /var/redmine/git_repositories

</pre>

Note the second line: it changes the ownership of the newly created directory to the user @rails@ and the group @rails@. Of course, you have to replace it according to your server settings (it can be @www-data@, @apache@ or when you are having a very bad sysadmin: @root@). Keep in mind that this user needs to have the (local-)permissions to run the @git@ command.

h4. Create the bare repository

After the preceding steps have been taken it is time to create our bare repository:

<pre>

$ pwd

/var/redmine/git_repositories

$ git clone --bare git://github.com/ook/donebox.git donebox.git

Initialized empty Git repository in /var/redmine/git_repositories/donebox.git/

remote: Counting objects: 401, done.

remote: Compressing objects: 100% (246/246), done.

remote: Total 401 (delta 134), reused 401 (delta 134)

Receiving objects: 100% (401/401), 179.55 KiB | 185 KiB/s, done.

Resolving deltas: 100% (134/134), done.

$ cd donebox.git

$ git remote add origin git://github.com/ook/donebox.git

</pre>

Our bare repository is now created successfully! Now go to your Redmine project settings, go to the repositories tab and choose @git@ as the SCM, then put in the "Path to .git directory" (in our example this is @/var/redmine/git_repositories/donebox.git/@) and save the settings. Have a look at your repository tab: you should now be able to browse your repository successfully.

Note: of course, this git repository won't update by itself. You'll have to @git fetch@ it regulary by hand, set up a cron job which will execute the @git fetch@-command automatically for you or use a post-receive hook, like this one : 

<pre>

echo "Post receive-hook => updating Redmine repository"

sudo -u my_redmine_user -p secret perl -we '`cd /redmine/repositories/my_repo.git && git fetch && git reset --soft refs/remotes/origin/master`'

</pre>

Note the git reset, you'll *need it* to update the git tree and see your changes in the Repository view. The 'soft' option is required since it is a bare repository and the default option (mixed) will fail since there is no working tree.

If you are using github, you can use the [[Plugin_List#Github-Hook-plugin|Github Hook Plugin]]

h4. Bare repository on Windows

If your bare repository is install on *Windows*, adding :

<pre>;%GIT_PATH%\cmd;%GIT_PATH%\bin;</pre> to your %%PATH%% environment variable.

Where %%GIT_PATH%% is the install directory of Git (eg: _C:/Git_)

h4. Setting up a mirror repository (shortcut, tracking branches)

The method above works fine under most circumstances but it can take a lot of tweaking to get certain things working if you have more than just a master branch. More information on the problem and the solution can be found on this "Stack Overflow question":http://stackoverflow.com/questions/4698649/how-do-i-get-a-remote-tracking-branch-to-stay-up-to-date-with-remote-origin-in-a.

This method will help to keep branches from the repository's origin updated and visible in Redmine's repository browser. This is really only relevant if the local copy of the repository is only being used as a read-only copy specifically for Redmine's use. For example, the project is hosted on GitHub but Redmine is being used for issue tracking.

<pre>

$ pwd

/var/redmine/git_repositories

$ git clone --mirror git://github.com/ook/donebox.git donebox.git

Initialized empty Git repository in /var/redmine/git_repositories/donebox.git/

remote: Counting objects: 717, done.

remote: Compressing objects: 100% (561/561), done.

remote: Total 717 (delta 320), reused 371 (delta 134)

Receiving objects: 100% (717/717), 211.35 KiB | 86 KiB/s, done.

Resolving deltas: 100% (320/320), done.

$ cd donebox.git

$ git branch

</pre>

This method relies on the @--mirror@ option available for the git clone command. This option may not be available to older versions of git. In that case, please reference the "Stack Overflow question":http://stackoverflow.com/questions/4698649/how-do-i-get-a-remote-tracking-branch-to-stay-up-to-date-with-remote-origin-in-a for some ideas on how to setup this type of mirror functionality without using the @--mirror@ option.

h3. Mercurial repository

To synchronize with a Mercurial repository, you will have to have a local clone of the repository on the same server you have Redmine installed on. Let's say you put Redmine in /var/www/redmine.example.com/www and have put your mercurial repository in /var/www/sources.example.com/repo/example, you would have to select *Mercurial* as a SCM, then enter */var/www/sources.example.com/repo/example* in the repository text box.

This will start checking out the Mercurial repository, and you won't see the results straight away. Wait for a few seconds (or possibly minutes), and click the *Repository* tab of your project (not of your configuration settings). You should now see the results appear.

h3. Bazaar repository

Put in the full path to your repository in "Root directory"

i.e. /home/username/bzr/repo/trunk

You'll need to make sure that bzr and bzrlib can be found in ENV['PATH'] and ENV['PYTHONPATH'] respectively.

ie. edit config/environment.rb and add:

<pre>

ENV['PYTHONPATH'] = '/path/to/pythonlib'

ENV['PATH'] = "#{ENV['PATH']}:/path/to/bzr/bin"

</pre>
