## JSON Remote Procedure Call (RPC) Interface

*SINCE 0.7.0*

Gitblit optionally allows a remote client to administer the Gitblit server.  This client could be a Java-based tool or perhaps a tool written in another language.

    web.enableRpcServlet=true
    web.enableRpcAdministration=false

**https** is strongly recommended because passwords are insecurely transmitted form your browser/rpc client using Basic authentication!

The Gitblit RPC mechanism, like the Gitblit JGit servlet, syndication/feed servlet, etc, supports request-based authentication.  Making an *admin* request will trigger Gitblit's basic authentication mechanism.  Listing of repositories, generally, will not trigger this authentication mechanism unless *web.authenticateViewPages=true*.  That means its possible to allow anonymous enumeration of repositories that are not *view restricted* or *clone restricted*.  Of course, if credentials are provided then all private repositories that are available to the user account will be enumerated in the JSON response.

### RPC Client

An example Java Swing [RPC Client application](http://code.google.com/p/gitblit/downloads/detail?name=rpcclient-%VERSION%.zip) is available and allows remote administration of repositories and users.  
This application exercises most methods from the utility class `com.gitblit.utils.RpcUtils`.

### EGit "Import from Gitblit" Feature (Planning)

One obvious goal of a Gitblit RPC mechanism would be to have an EGit Feature that allows authentication and enumeration of Gitblit repositories from the Eclipse *Import...* menu.  Cloning (hopefully batch) would be delegated to EGit.

This particular project should not be difficult as the only external dependency for `com.gitblit.utils.RpcUtils` is [google-gson](http://google-gson.googlecode.com) which is already a dependency of the EGit/GitHub Mylyn feature.

Currently this project is in the planning stage.

### Example: LIST_REPOSITORIES

**url**: https://localhost/rpc?req=LIST_REPOSITORIES  
**response body**: Map&lt;String, RepositoryModel&gt; where the map key is the clone url of the repository
<pre>
{
  "https://localhost/git/libraries/xmlapache.git": {
    "name": "libraries/xmlapache.git",
    "description": "apache xmlrpc client and server",
    "owner": "admin",
    "lastChange": "2010-01-28T22:12:06Z",
    "hasCommits": true,
    "showRemoteBranches": false,
    "useTickets": false,
    "useDocs": false,
    "accessRestriction": "VIEW",
    "isFrozen": false,
    "showReadme": false,
    "federationStrategy": "FEDERATE_THIS",
    "federationSets": [
      "libraries"
    ],
    "isFederated": false,
    "size": "102 KB"
  },
  "https://localhost/git/libraries/smack.git": {
    "name": "libraries/smack.git",
    "description": "smack xmpp client",
    "owner": "admin",
    "lastChange": "2009-01-28T18:38:14Z",
    "hasCommits": true,
    "showRemoteBranches": false,
    "useTickets": false,
    "useDocs": false,
    "accessRestriction": "VIEW",
    "isFrozen": false,
    "showReadme": false,

    "federationSets": [],
    "isFederated": false,
    "size": "4.8 MB"
  }
}
</pre>

### Example: EDIT_REPOSITORY (rename)

The original repository name is specified in the *name* url parameter.  The new name is set within the JSON object.

**url**: https://localhost/rpc?req=EDIT_REPOSITORY&name=libraries/xmlapache.git  
**post body**: RepositoryModel
<pre>
{
    "name": "libraries/xmlapache-renamed.git",
    "description": "apache xmlrpc client and server",
    "owner": "admin",
    "lastChange": "2010-01-28T22:12:06Z",
    "hasCommits": true,
    "showRemoteBranches": false,
    "useTickets": false,
    "useDocs": false,
    "accessRestriction": "VIEW",
    "isFrozen": false,
    "showReadme": false,
    "federationStrategy": "FEDERATE_THIS",
    "federationSets": [
      "libraries"
    ],
    "isFederated": false,
    "size": "102 KB"
}
</pre>

### Example: LIST_USERS
**url**: https://localhost/rpc?req=LIST_USERS  
**response body**: List&lt;UserModel&gt;
<pre>
[
  {
    "username": "admin",
    "password": "admin",
    "canAdmin": true,
    "excludeFromFederation": true,
    "repositories": []
  },
  {
    "username": "test",
    "password": "test",
    "canAdmin": false,
    "excludeFromFederation": false,
    "repositories": [
      "libraries/xmlapache.git",
      "libraries/smack.git"
    ]
  }
]
</pre>
