Re: [udig-devel] update sites on by default

[Jody Garnett <jody.garnett@xxxxxxxxx>]

I took another run at this (ie exporting with generating a metadata repository for P2).

Ended up taking a lot of unused stuff out of our udig_lanaguage feature (ie translations of parts of eclipse we don't use).

I then proceed to go though and fix each of the features so that there dependencies reflected reality (you can ask eclipse to manage that for you when plugins are added/removed from a feature) but we do not.  Looking at eclipse features they never seem to have this dependency section filled in?

Finally I got to the stage where all udig features worked; and it could not export out the org.eclipse.rcp feature :-(  Right now we include the org.eclipse.rcp feature in our udig-feature so we export out everything we need. I tried moving it from the udig-feature to the udig.product - but got the same kinds of failure.

The failures amounted to being unable release org.eclipse.rcp due solaris gtk (or some such).

I have rolled back my attempt.

Going to need some collaboration and doc reading to get this one done.

Update site P2 progress.

I have been able to remove the update manager since P2 is now available; and have been able to directly make use of "org.eclipse.equinox.p2.user.ui" in our udig.product.

The resulting application "is not configured" for software update however ....

First step is to add a "p2.inf" file next to udig.product:

instructions.configure=\

  addRepository(type:1,location:http${#58}//udig.refractions.net/files/update/1.2/udig/);\

  addRepository(type:0,location:http${#58}//udig.refractions.net/files/update/1.2/community/);

To test we need to be able to export the product *with* "Generate metadata repository":

The Generate metadata repository option allows you to also generate p2 metadata along with yourexported feature. This does not create a p2-enabled product, just the metadata which can then be used to install using p2.

I would like us to proceed in this direction, a p2 update site, for the uDig 1.2.0 release as P2 is being formally used in Eclipse 3.6 and I understand the old eclipse update manager is no longer used. 

Next steps?

- read the online help[1] [2] [3]

- generate p2.inf or categorization information for each udig feature we release

- get export product working with generating metadata repository

--- notes while trying this out ----

Release *with* the "Generate metadata repository" checkmark. I suspect this will fail; I bet we need to add a p2.inf file to each one of the features we use?

Export failed with ...

So we are tripping up over language files? We did create a feature udig_language to include only those BABLE plugins that we actually use ... and it is our first failure.

It is finally answering what that "generate metadata" checkmark is for when releasing a product (sigh!).

Trying to go a bit more slowly; do you have a bug report or notes describing what you are doing?

- do we need to grab a new update manager for uDig? (answer: probably I would expect so....)

- the commit has been added to trunk? Or to the tag...

- what was the fix?

With respect to p2.inf I found the following online:

- http://wiki.eclipse.org/Equinox/p2/Customizing_Metadata

As for deploying, it is tempting to just release 1.2.0 rather then another RC :-) An update site was one of the items we want for the 1.2.0 release.

Hi Jody,

I have tried hard to get the community site listed by default but

couldn't find a way, or better, eclipse seems to provide a nice way

(p2.inf file in the bundle), btu it seems that the update manager used

in udig doesn't like it that much.

Mauricio anyways committed the fix that makes it possible to install

from the community update site (if added manually).

So there should be green light to deploy udig.

A bit sad that we do not have the sites listed...

ciao

Andrea
