| <p><i>Checklist:</i></p> |
| <ul> |
| <li>Create new XML plug-in containing the XML Pull APIs.</li> |
| <li>Remove plug-in dependancies from org.eclipse.core.runtime and org.eclipse.core.resources.</li> |
| <li>Add new dependancy to new XML plug-in.</li> |
| <li>Replace org.eclipse.core.internal.plugins.PluginParser with a new |
| parser using the new APIs.</li> |
| <li>Replace org.eclipse.core.internal.resources.WorkspaceDescriptionReader |
| with new reader based on new APIs.</li> |
| <li>Replace org.eclipse.core.internal.resources.ProjectDescriptionReader |
| with new reader based on new APIs.</li> |
| <li>Determine interaction with bootstrap process. Things to consider include |
| creating the bootstrap classloader, update/install, and org.eclipes.core.internal.boot.PlatformConfiguration.</li> |
| <li>Check test suites.</li> |
| <li>Verify new work by completely removing the Xerces plug-in from the |
| environment. (is this possible with the other plug-ins' dependancies?</li> |
| <li>Educate Platform/UI and other teams in SDK who rely on Xerces with |
| knowledge of new APIs. Note that most teams have updated the bug report |
| with explanations of their usage.</li> |

| <p><em>October 20, 2003</em></p> |
| <ul> |
| <li>Since Eclipse now requires a 1.4 VM, we have decided to program against |
| the JAXP APIs for now rather than including a new XML Parser (like XML |
| Pull) in the SDK.</li> |
| <li>Perhaps in the future we will switch to a highly performant parser |
| in the Core Runtime to parse plugin.xml files.</li> |
| <li><a href="http://dev.eclipse.org/mhonarc/lists/eclipse-dev/msg04227.html">Message</a> |
| sent to mailing list and newsgroup.</li> |
| <li>Core has removed their dependancy on Xerces and programmed against |
| JAXP.</li> |
| <li>Other plug-ins in the SDK are following suit.</li> |
| </ul> <p><em>September 2, 2003</em></p> |
| <ul> |
| <li>Still waiting for approval before moving on.</li> |
| </ul> |
| <p><em>July 21, 2003</em></p> |
| <ul> |
| <li>We are awaiting to see if we can get approval to include an XML Pull |
| implementation in the SDK download</li> |
| <li>Working out licensing issues with the developers of a particular XML |
| Pull implementation. (inconsistencies between code and web site)</li> |
| <li>Have asked for the teams in the SDK to indicate where they use XML |
| in their code. Almost every single Eclipse team has replied that they |
| use XML somewhere in their code! Still need to review these uses and |
| plan for migration.</li> |

| <td><p><strong>Milestone Plans</strong> |
| <p><em>3.0 M5 - November 21, 2003</em></p> |
| <ul> |
| <li>Remove dependancy on Xerces for all SDK plug-ins.</li> |
| <li>Remove Xerces plug-in from SDK download? Need approval from PMC before |
| this can happen.</li> |
| </ul> <p><em>3.0 M4 - October 10, 2003</em></p> |
| <ul> |
| <li>Get the code released into the repository. Still waiting on approval |
| before this can be done.</li> |
| </ul> |
| <p><em>3.0 M3 - August 29, 2003</em></p> |
| <ul> |
| <li>Continue towards completing the above outlined tasks.</li> |
| <li>Hope to have approval for XML Pull use shortly after 3.0 M2 and then |
| will be able to release new code into HEAD.</li> |
| </ul> |
| <p><em>3.0 M2 - July 18, 2003</em></p> |
| <ul> |
| <li>Goal is to complete all of the above work.</li> |
| <li>We don't envision having all teams converted to new APIs but should |
| at least be educated on how to convert their code. It is up to the individual |
| teams to 1) determine whether or not they want to convert their code |
| and 2) to actually change their code.</li> |
| <li>Note that although all plug-ins in the SDK are not required to convert |
| their parsing, it is necessary that at least the plug-ins defined to |
| be a part of the Rich Client Platform (RCP) perform this transformation. |
| Reducing the size of the XML plug-in shipped with the RCP (3M for Xerces |
| vs 25K for XmlPull) is a big big win.</li> |
