Re: [equinox-dev] Should osgi deprecate the location term?


I think the problem is a little bit deeper. In some cases it really is a location: the one parameter BundleContext.installBundle and the no parameter Bundle.update. I think the bug misstates the issue a bit. Tom, you seem to imply that a location must be a URL, which I think is a rather narrow view of location. Also a URL can always be mapped to a string, so it can (should) be used as a location.

It seems to me that the problem you are alluding to in the bug has more to do with it's misuse as a way of keeping meta data information about a bundle than poor location semantics.

Was "Fw: [Bug 126517] New source lookup is broken"


I opened an issue against OSGi to discuss this topic for the next specification release.

Should we put this on the list of things to propose in the next version of the OSGi spec?  deprecate getLocation() (and the use of the term location) and replace with getInstallKey() or some such?  This always crops up and confuses people.

'location' is used to hold the poorly named OSGi concept of bundle location
(see Bundle#getLocation).  This value is assigned by the caller to
BundleContext#installBundle.  

The location string can be anything, it does not have to be a well formed URL
string or file path string.  Therefore we cannot merge the two.  The best
definition I can come up with for the true meaning of bundle location would be
"install key".  It is a key assigned by the installer (not the framework) at
install time.  Update uses keys starting with "update@" so they can easily tell
what bundles they manage.
