Subject Re: [jira] Created: (FELIX-1300) Remove legacy bundle cache support when extracting embedded JAR files
Date Fri, 03 Jul 2009 17:59:01 GMT

What does this mean for my framework bundle cache created with a current
framework when upgrading to framework 2 ? Will the bundle cache be
migrated or just be used as is ?

Thanks and Regards

> A while ago we modified IContent so we could use that interface to extract JAR files,
which was necessary for fragment support where we needed to be able to access embedded content
to construct the host class path. The approach is actually more powerful than what is necessary,
since we allow JAR files to be extracted from embedded JAR files and JAR files embedded in
the embedded JAR files to be extracted and so. As a result of this, you can end up with situation
where embedded JAR files in different embedded JAR files may have the same name, so to avoid
name clashes, we extract embedded JAR files into a directory named after the bundle. This
was problematic at the top-level, since it would not be backwards compatible with existing
caches. As a result, we special case the top-level and just use the name "embedded" for the
directly as was done in the past. With the move to 2.0, I want to remove this legacy since
there isn't much point to keeping it.
