Re: [cross-project-issues-dev] [Bug 185052] [europa] installable feature

[Eric Jodet <jodet.e@xxxxxxxxxx>]

Ed,
the idea here is to find a way to optimize
the number of plugins loaded at startup.
As you may find out with other Eclipse
based IBM Toolkits, europa may be installed across the enterprise as the
standard dev toolkit.
But some people may perform only (or
mainly) Database work, whereas others C/C++ or Java and so on...
Disabling unused features may help minimize
the resources allocated when using europa.

In fact, after installing a feature,
the default would be to enable the feature.
The idea here is to give the end-user
the possibility to disable any additional feature.

Eric.

Eric,

For EMF we have capabilities defined in an example plugin.  We ran
into
problems with providing these as an actual part of our standard feature
since IBM products wanted to define their own notion of what functions
fits
in what capability categories.  So if the idea is that Europa will
now
deliver on the order of 20 or more categories out of the box, I'm not sure
that's a great idea.  Is it possible to use capabilities to filter
out
capabilities themselves so they can be redefined differently by a client
who has their own notion of how best to group the function contributed
by
various Eclipse projects into categories of capability?  I fear that
an
uncoordinated effort will just result in a hodgepodge of categories and
I
don't think EMF will be in a position to contribute to that (and reading
the bugzilla I don't think EMF loads plugins before their time is right).
So a word of caution, be careful what you ask for, you may get it.

I also wonder if people think it's realistic to ask others to ship their
features with their capabilities disabled.  I know that when people
install
EMF directly they are really expecting it to be enabled and I'm sure every
project is in the same position in that regard.  Is there a declarative
mechanism whereby products could change the default enablablement state
of
various capabilities?

Hello,
please have a look at bug
https://bugs.eclipse.org/bugs/show_bug.cgi?id=185052.

As proposed by Daniel, I'm gonna open one individual bug per Europa project
/ feature.
The main idea here is to contribute the General / Capabilities in order
for
the user
to be able to enable/disable any project / feature individually, to prevent
multiple plugin loading at startup
as it's currently the case.
This would benefit the overall startup performance, as well as it might
improve/optimize resource usage after startup.

Thanks.
Eric.
