## Remote Management, Administration and Integration

*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.enableRpcManagement=false
    web.enableRpcAdministration=false

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

The Gitblit JSON 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.

### Gitblit Manager

[Gitblit Manager](http://code.google.com/p/gitblit/downloads/detail?name=%MANAGER%) is an example Java/Swing application that allows remote management (repository and user objects) and administration (server settings) of a Gitblit server.
  
This application uses a combination of RSS feeds and the JSON RPC interface, both of which are part of the [Gitblit API](http://code.google.com/p/gitblit/downloads/detail?name=%API%) library, to present live information from a Gitblit server.  Some JSON RPC methods from the utility class `com.gitblit.utils.RpcUtils` are not currently used by the Gitblit Manager.

**NOTE:**  
Gitblit Manager stores your login credentials **INSECURELY** in homedir/.gitblit/config.

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

One obvious goal of a Gitblit RPC mechanism would be to have an Eclipse/EGit Feature that allows authentication and enumeration of Gitblit repositories from the Eclipse *Import...* menu.  Batch cloning would be supported and 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.

One proposal from the EGit team is to define a common JSON RPC method for enumeration of repositories which can be implemented by Git hosts.  The EGit team would then implement the UI and the client-side enumeration code.  This idea was raised as part of this [feature request for EGit](https://bugs.eclipse.org/bugs/show_bug.cgi?id=361251).

Currently this project is in the planning stage.

## RSS Query Interface

At present, Gitblit does not yet support retrieving Git objects (commits, etc) via the JSON RPC mechanism.  However, the repository/branch RSS feeds can be used to extract log/history information from a repository branch.

The Gitblit API includes methods for retrieving and interpreting RSS feeds.  The Gitblit Manager uses these methods to allow branch activity monitoring and repository searching.

<table class="table">

<tr><td colspan='3'><b>standard query</b></td></tr>
<tr><td><em>repository</em></td><td><em>required</em></td><td>repository name is part of the url (see examples below)</td></tr>

## JSON Remote Procedure Call (RPC) Interface

### RPC Protocol Versions
<table class="table">
<tbody>
<tr><th>Release</th><th>Protocol Version</th></tr>
<tr><td>Gitblit v0.7.0</td><td>1 (inferred version)</td></tr>
<tr><td>Gitblit v0.8.0</td><td>2</td></tr>
<tr><td>Gitblit v0.9.0 - v1.0.0</td><td>3</td></tr>
<tr><td>Gitblit v1.1.0</td><td>4</td></tr>
<tr><td>Gitblit v1.2.0+</td><td>5</td></tr>
<tr><td>Gitblit v1.3.1+</td><td>6</td></tr>
</tbody>
</table>

#### Protocol Version 5

- *SET_REPOSITORY_MEMBERS* will reject all calls because this would elevate all discrete permissions to RW+  
Use *SET_REPOSITORY_MEMBER_PERMISSIONS* instead.
- *SET_REPOSITORY_TEAMS* will reject all calls because this would elevate all discrete permissions to RW+  
Use *SET_REPOSITORY_TEAM_PERMISSIONS* instead.
