First of all, to make Git file store available, you need to add <code>org.eclipse.orion.server.filesystem.git</code> and all dependencies to your launch configuration. If you're missing a dependency you should probably re-import project set from webide.psf. If it didn't help, ping z4z4 on [[IRC]] (use #eclipse-orion channel).

Orion will create a local clone of the repository and store it on the server. The user will be not aware of the local clone, so the git repository location specified by the user is the only copy of the code the user knows about. His changes will be saved in the file system on the server and then automatically added to the git index and comitted to the local repository/clone. The local clone is required by the git client if we want to push the changes back to the external git repository (eg. located on github.com). Each user will have his own copy (local clone) of the remote git repository once he created/linked a new project (separate folder on the server). The problem is that we currently don't know [https://bugs.eclipse.org/bugs/show_bug.cgi?id=334120 how to push Git changes over SSH without storing a private key on the Orion server].

C) Another option is to clone an existing repository, but make it bare while doing so. This way you can check out a project from GitHub and share your work with others at the same time. You won't be able to push your changes back to the GitHub though (see [https://bugs.eclipse.org/bugs/show_bug.cgi?id=334120 bug 334120] and the problem described above).

Linking to a git clone already existing on your computer

  1. First [clone] a git repository to any location in your local filesystem, you can do with a tool of your choice (EGit, msysgit...)
  2. Download and run Orion
  3. Create a project and link it to the location you used in Step 1.
  4. Orion will automatically detect that the project is actually a git clone (we will probably make it configurable in the future)

Linking to a git repository using git file store

  1. Download and run Orion
  2. Make sure org.eclipse.orion.server.filesystem.git is added your launch configuration
  3. When linking a project select gitfs, enter URL for a git repository and leave Module empty
  4. If you entered an existing location on your computer it must be a cloned repository, we won't be doing any smart detection here Howtogit--link folder dialog2.png
  5. For a git repository which requires authentication (e.g. starts with ssh://) to be able to clone it (and also fetch and push) you will need to wait for bug 334120 to be fixed Howtogit--link folder dialog.png

git REST API

Getting status for a git project

Overview
To retrieve the working tree status of a project, send a GET request to the git status location.
HTTP Method
GET
Example Request
GET /git/status/file/MyProj/
Example Response
HTTP/1.1 200 OK
 Content-Type: text/plain
 Content-Length: 22

TBD
Detailed Explanation
TBD.


Progress in being tracked on bug 337212. This section will be moved to Orion/Server_API once the API get stable.

Getting a diff

Overview
To retrieve changes changes between selected commits, commit and working tree, and so on. Send a GET request to the git diff location.
HTTP Method
GET
Example Request
GET /git/diff/file/MyProj/
Example Response
HTTP/1.1 200 OK
 Content-Type: text/plain
 Content-Length: 22
