Re: [equinox-dev] Announcement: Aspects Equinox Incubator - Phase II

[Matthew Webster <matthew_webster@xxxxxxxxxx>]

Jeff,

I have been working on an Update Site
which will include the framework extension and the weaving service bundle.
It will pre-req (and may automatically install when I figure out how to
do it) AJDT both for building the demos and running them. However also
I need a _reliable_, simple and reversible way to replace the installed
org.eclipse.osgi_3.2.0.v20060601.jar system bundle with one that includes
supplements support. This is proving difficult. Any help in this regard
would be very welcome. My attempts so far have been a little frustrating.

I have created a separate feature (but
part of the same update site as the Aspects Equinox Incubator) which includes
a modified version of org.eclipse.osgi. This would enable users to disable
the supplements feature while continuing to use the remainder of the Aspect
Equinox Incubator and demos that only require the opt-in model. Building
the update site creates an  org.eclipse.osgi_3.2.0.200611131112.jar
(without "v") which installs fine and after the target workspace
is automatically restarted works fine as well. Unfortunately if I _subsequently_
restart the workspace Eclipse reverts to the previous version of Equinox
and the demos fail. Hmmm!

I decided to manually set the version
qualifier and created org.eclipse.osgi_3.2.0.v20061113.jar (with "v").
This also installs fine by does not work after the automatic restart. However
if I subsequently restart the workspace Eclipse _does_ pick up the new
bundle. Hmmmmmmmmmm!

What am I doing wrong? Does Eclipse
not support updating the system bundle? Could I do this successfully by
implementing my own org.eclipse.rcp _feature_ containing just the new version
of org.eclipse.osgi?

Thanks in advance

I'm not sure that https://bugs.eclipse.org/bugs/show_bug.cgi?id=143696
is ever going to be fixed.  There are a couple ways of looking at
this 
1) people who are developing phase II extensions will need to have OSGi
in their workspace (since they have the extensions in their workspace).
 We can have a project set file that helps them get what they need
with one click.  We have started using these more pervasively (see
http://www.eclipse.org/equinox/server/http_in_container.php) to good effect.

2) people who just want to use this stuff can get the framework fragment
and add it to their target.  Having a built version of that available
on an update site or just as a JAR (or in a zip) would be great.

Actually, step 3 indicates that you need the OSGi bunle from the aspects
branch but then towards the end it says you need the source version of
OSGi that matches the one you have in your SDK.  So does the aspects
work have any changes to the OSGi bundle or is everything done in an extensoin?

For all the tests and examples, perhaps you can supply a project set file?

Pascal, 

> Is downloading the source code necessary? 
It's not great. I should create an update site. Not sure if this will work
for the replacement org.eclipse.osgi though. You will of course still need
the source for the demos and maybe the tests 

>Is the download of AJDT required? or is this just for ease of aspect
authoring? 
It is required because you will of course need it to build the demos but
more importantly it includes AspectJ which is needed for the load-time
weaving (org.aspectj.weaver bundle) and running your woven program (org.aspectj.runtime).
When I create an update site and could include AJDT as a pre-req.

>Personally I think it would greatly help if the number of steps was

I don't quite follow. 

>In any event, all that sounds really cool, 
I certainly hope so.

I just went to the getting started page and it does not sound appealing
/ easy. 
- Is downloading the source code necessary? 
- Is the download of AJDT required? or is this just for ease of aspect
authoring? 

Personnaly I think it would greatly help if the number of steps was limited
and the downloads from the fwk extensions and other bundles could be availalble
for dl too. 

In any event, all that sounds really cool, 

PaScaL

Subject	[equinox-dev] Announcement: Aspects Equinox Incubator - Phase II

The Aspects Equinox Incubator project is pleased to announce the availability
of Phase II. This code comprises supplements support in org.eclipse.osgi,
new tests and Eclipse-based demos that show the power of the co-opt model.
Please see the description of how to get started on the Aspects home page
(http://www.eclipse.org/equinox/incubator/aspects/index.php).
