Hi p2ers,
We (ECF) would like to release a new version of our bundles (ECF 3.2) on
Feb 19...in order to make available our impl of OSGi 4.2 remote services
[1] among some other new things. This release is something that a
number of ECF consumers are waiting on and anticipating, and we want to
make things available as soon as possible. We've had our review, etc.
To support the OSGi spec, however, some small additions to the ECF core
bundles (i.e. org.eclipse.ecf and org.eclipse.ecf.identity) are
required. These are truly additions...and do not affect backward
compatibility.
The ECF/identity bundles are included in the set distributed with
p2/Eclipse...to support file transfer. More specifically, these two
bundles are part of the org.eclipse.equinox.p2.ui feature. Currently,
the o.e.e.p2.ui feature includes a fully qualified version of ECF core
in the feature, and unfortunately this means that we/ECF cannot update
these bundles in our SDK, as p2 refuses to install a newer version of
the ECF core bundle, given that the p2.ui feature specifies a particular
version of ECF. Thomas Hallgren has opened this bug [2] so that this
same problem can be avoided in the Helios release (thanks Thomas). We
would highly appreciate having this bug addressed before Helios...so
future difficulties can be avoided.
In order to get around this for our 3.2 release on Eclipse 3.5.X, we are
thinking that we will produce a feature patch...to allow us to update
our core/identity bundles to a recent version that includes the osgi
remote services support. First: creating a feature patch seems like
the easiest best way for us to allow ECF 3.2 to be installed on
3.5.X...but there may be other options possible...if so, please let us know.
Second: I have created a feature patch project, and have a question:
Can the o.e.e.p2.user.ui feature version be specified as '0.0.0', so as
to allow the use of a single feature patch for use with any version of
o.e.e.p2.user..ui feature? Specifically, will this work (from
feature.xml for the feature patch)?
<requires>
<import feature="org.eclipse.equinox.p2.user.ui" version="0.0.0"
patch="true"/>
</requires>
Will this have the desired effect? (i.e. allowing a single feature patch
to be used to update multiple versions of
org.eclipse.equinox.p2.user.ui?). Is there some other acceptable
version that will have the desired effect?
Thanks,
Scott
