Re: [platform-update-dev] Dependancies sort of like RPM

Kurt,

The 2.0 spec is posted on the Development Resources page of the
Install/Update component.

In regards to your question, Install/Update 2.0 does provide for
dependencies, but these dependencies are on a plug-in level. A feature
contains references to plug-ins. It can also specify plug-ins it needs
before it can be installed. If these plug-ins are missing on the target
platform, Install/Update UI should warn you about it and offer you to
search for features that has these plug-ins. However, it cannot directly
install the plug-ins because it can only install features, and more than
one feature can contain references to the missing plug-ins.

For example, you may be missing org.eclipse.ui. This plug-in may be found
in a number of features (Eclipse platform feature, IBM WSAD feature etc.).
Update UI will show you the search result and you would have to pick from
the list. By installing a feature that contains the missing plug-ins, you
would resolve the problem.

Will the new Install/Update features planed for Eclipse allow dependencies
(both for other plugins and specific versions of those plugins).   It would
be nice if it worked similar to the redhat RPM package installer.   If you
attempt to install a plugin that has dependencies, and those dependencies
are not met, a window would show a list of those plugins AND allow you to
click on the non-met dependencies and get them and install them.
So from the users perspective, the update/install could keep walking a tree
of dependencies updating and installing along the way.  If the system gave
the user the option to "auto install dependencies" the entire process would
be painless.

Is there a link that describes the design of the install/update?
