| <h1> |
| Local History Improvements</h1> |
| <i><font size=-1>Last revised 13:30 Monday February 11, 2002</font></i> |
| <p>This note summarizes proposed additions and changes to Eclipse Platform Core |
| and UI to improve the local history facility, which exists to help the user |
| recover from unwanted changes to, or deletion of, files in their workspace. |
| <h3>Ensure local history is captured</h3> |
| <p>In Eclipse 1.0, many operations that the user performs do not capture the |
| previous state of the file in the local history as the user might reasonably |
| expect. This stems from inconsistent use of Core APIs on the part of the |
| Workbench and other plug-ins. Part of the fault can be blamed on the lack of an |
| IResource.delete method that captures local history (the delete methods that |
| keep local history are only to be found on the interfaces for the specific |
| resource types; e.g., IFile).</p> |
| <p>The proposal is two-fold:</p> |
| <ul> |
| <li>Add methods to IResource and IWorkspace to allow clients to easily keep local history |
| for deleted files.</li> |
| <li>Establish guidelines about how to use the local history mechanism.</li> |
| </ul> |
| <h3>Recovering deleted files</h3> |
| <p>Once a file has been deleted, the file no longer manifests itself in the |
| workbench UI. Even if there are states of the file preserved in the local |
| history, there is no obvious way for the user to browse them and perhaps |
| retrieve one.</p> |
| <p>The proposal is two-fold:</p> |
| <ul> |
| <li>Add Core API so that clients can conveniently discover which files have |
| entries in the local history.</li> |
| <li>Add Workbench UI so that users can readily discover and recover recently |
| deleted files.</li> |
| </ul> |
