Re: [dash-dev] tool to delete one repo from other repo

[Nick Boldt <nickboldt@xxxxxxxxx>]

If you have a composite repo, you can add/remove repos to/from the composite.

The metadata for compositing multiple repos is dead simple to create (either with a tool or by hand); there is tooling to add/remove from an existing repo too.

So... instead of creating a single repo which overlaps the product, you could create two (or more) repos which contain complimentary sets of IUs.

This is what we do for JBoss Developer Studio: we have one repo that contains the stuff from Eclipse.org we need (Web Tools, etc.), a second one with JBoss Tools' features, a third with third-party items (SpringIDE and TestNG) and a fourth with some experimental stuff. Then these sites can be combined into a single site from which to provide updates.

We also composite sites together to make testing easier and be able to build aggregate update sites more easily.

Here's a sample of the metadata files:

http://download.jboss.org/jbosstools/builds/staging/_composite_/trunk/compositeArtifacts.xml

http://download.jboss.org/jbosstools/builds/staging/_composite_/trunk/compositeContent.xml

For more (and some discussion of the tooling available), see:

thanks Paul,
ah I overlooked p2.remove.ui on this page!
It doesn't perfectly suit my needs because I have to list exact IUs to remove, whereas I have a whole repo.
But maybe there's an easy way to turn a repo into list of IUs and then turn that list into p2.remove.ui calls... :-)

hi Relengs,

I have a repo that will always be installed on top of some product, but content of repo and this product overlaps a bit.
Because repo will be distributed in some old fashioned way (like a floppy drive:-) ), I want it to be as small as possible.
So I want all IUs that are in the product to be removed from repo.


You can do it as part of PDE build, there's a  p2.remove.iu task.  We were using it in the e4 build (commented out in the postSetup task ATM):

http://dev.eclipse.org/viewcvs/viewvc.cgi/e4/releng/org.eclipse.e4.builder/builder/general/customTargets.xml?view=co&revision=1.90.2.4&content-type=text%2Fplain

See http://help.eclipse.org/helios/index.jsp?topic=/org.eclipse.platform.doc.isv/guide/p2_repositorytasks.htm for full syntax.

Later,
PW
