There is code within Felix that "normalizes" PPC to powerpc within the

It wouldn't be needed if you put all of the aliases into the constructed
native capability.

Hi Richard,
Here's an approximation of what the CT code is doing:
//First we get the native requirement for filters
String filterDirective = "(&(osgi.native.osname~=mac os
x)(osgi.native.processor~=powerpc) )"
//Create filter object
Filter filter = getContext().createFilter(filterDirective);
//Mock what the framework would be providing
Map macPPC = new HashMap();
macPPC.put("osgi.native.osname", "Mac OS X");
macPPC.put("osgi.native.processor", "PPC");
assertTrue("filter does not match map: " + filter +
".matches(" + macPPC+ ")", filter.matches(macPPC));
The above fails since the CT test would not go through any logic to
add aliases to the macPPC object. Does this help or are you looking
for something else?
Yeah, that helps and I agree that seems odd.
It doesn't really seem like a valid test to me, since the filter
shouldn't necessarily know anything about the native namespace aliases.
I'll check around.

Currently working on getting the OSGi R6 tests related to Native
Code. The tests failures that I'm working through start with the
name testNativeCode. The tests are failing on a
org.osgi.framework.Filter.matches() call between a raw map of
Native Attributes such as Procssor, OS name, etc and the Native
Namespace Filter Directive. The raw map of attributes is as follows:
{org.osgi.test.cases.framework.div.tb16=xyz,
org.osgi.test.cases.framework.div.tb15=abc,
osgi.native.osversion=1.0.0, osgi.native.language=en,
osgi.native.osname=Mac OS X,
org.osgi.test.cases.framework.div.tb12=abc,
osgi.native.processor=PPC}
I'm generating a filter which includes the following statement to
make it pass (I've truncated for brevity):
(&(osgi.native.osname~=mac os x)(osgi.native.processor~=powerpc)
"ppc" is an alias for "powerpc" as defined in Table 4.2 (page 100)
of the OSGi R6 specification. Per section 8.7 (page 170) we
should create a list of osgi.native.processor attributes under the
osgi.native namespace within the Provide-Capability to include
these aliases. Since the test is asserting the requirements are
met by calling org.osgi.framework.Filter.matches() method on a raw
map of attributes (no aliases) we would have to add all the
aliases in the Filter.matches method to ensure the tests would pass.
Any thoughts on how this should be handled? It seems like the
test is encouraging an implementation that is not optimal for the
framework. I think deriving the aliases would be best handled
once at startup rather than each time
org.osgi.framework.Filter.matches is called. Should the test be
changed or am I missing an implementation option that would solve
both concerns?
Not sure I completely understand. It is not clear to me what is
being invoked on what from where. Can you show me some pseudo-code
or something?
