WTP CVS Restructuring
In an effort to standardized groups on dev.eclipse.org especially in light of our recent WTP Refactoring, the page is to propose and document how to restructure our CVS directories, so their access can be managed by associating directories with Unix Groups.
The document will start by focusing on the old wst and jst directories, as they need the most work, and other subprojects addressed later, towards the end of this proposal.
WST and JST
These initial WTP projects were created with the following sort of hierarchy -- abbreviated and idealized here to simplify explaining the principles of the restructuring.
wst components assembly features plugins server features plugins tests xml features plugins org.eclipse.wst.xml.core org.eclipse.wst.xml.ui tests examples development thirdparty xsd plugins org.eclipse.wst.xsd.core org.eclipse.wst.xsd.ui tests
The new proposed structure would look as follows
webtools.releng features plugins webtools.sourceediting features plugins org.eclipse.wst.xml.core org.eclipse.wst.xml.ui org.eclipse.wst.xsd.core org.eclipse.wst.xsd.ui tests examples development thirdparty webtools.servertools features plugins tests
The above examples show a few points related to this restructuring.
- The best top-level name should "match" what the access group name will be: toplevel.subproject.component-subcomponent. We do not currently have components controlled by access restrictions, so I think we in webtools need only define the toplevel.subproject directories for now (this can change in the future, but best to start off with simplest, and add detail later, when needed.
- Thus, everyone in a certain subproject can be associated with the "highest" webtools directory, and automatically get access to everything lower, without the need for more than subprojects groups, for now.
- Note the previous "assembly" features and plugins will be become part of releng subproject. These are the "product" plugins, and the features that define our builds. Each project will be responsible for their own features delivered to WTP.
- Notes the example in source editing where what used to be directories, xml and xsd, are no longer distinguished by cvs directories, but all the plugins flattened under webtools.sourceediting/plugins.
- Conceptually and architecturally, xml and xsd could still be called 'components' but they do not have separate access control, so it's a bit overkill (and ultimately restrictive) to define them in separate cvs directories.
- Note that the "access control" for components such as xml and xsd is (still) social in nature. Legally, in theory, anyone in the source editing project could change the code there, but in practice, there are individuals or small teams that normally do. Others, even in the same project, usually would attach a patch to a bugzilla if they wanted one of those experts to review and commit the code.
To Do Items
- change maps to use module names only, to divide up the change, so once restructuring is done, only the modules file has to be changed, and builds will keep working. Note: there are probably some, JSF or JPA files that will have to be added to modules file. (Remember, any old builds, if they had to be re-created, would have to be changed, but that's unlikely to be needed).
- try using CVS snapshots, on local, test machines with some move scripts to test to be sure we've accounted for everything.
