Re: [equinox-dev] [prov] Some provisioning changes released

I'll investigate this. The change I
made should only have effect if you manually added filter elements to the
features before generating the metadata. However, it's possible I messed
something up or there's a collision between my changes and Pascal's. I'll
follow up here with findings.

Hmm. I picked up your changes and Pascal's. I regenerated the metadata.
When I attempt to install (an SDK) I get  a number of InvalidSyntaxExceptions
in FilterImpl$Parser: 

FilterImpl$Parser.parse_attr() line: 1627        

                    
   if
(length == 0) { 
                    
           throw
new
InvalidSyntaxException(NLS.bind(Msg.FILTER_MISSING_ATTR,
String.valueOf(pos)),
filterstring);
                    
   } 

when,  for example, the filter string is 

   (&((&(osgi.os=win32)(osgi.ws=win32)(osgi.arch=x86))) ((version>=3.3.0.v3339)))

and the message is 

        Missing
attr at character 3 

and the iu being processed is 

         org.eclipse.rcp.featureIU
3.3.0.v20070405a-8w8eDpEbsN3KkG_gP8JZLGb 

similar for platform.featureIU with filter string 

        (&((&(osgi.ws=win32))) ((version>=3.2.100.I20070319-0010)))

The problem appears to be with the handling of the compound conjunction.
A version filter only or an _expression_ like 

        (&(osgi.os=hpux)(osgi.arch=ia64_32))

parses without exception. 

Bugzilla reveals 3 bugs matching FilterImpl, none for this behavior. Is
it a bug or is this type of _expression_ not supported.

Subject	[equinox-dev] [prov] Some provisioning changes released

I released a couple of small to the provisioning incubator:

- New local metadata repository. If you create a metadata repository pointing
to a local file system directory, it will traverse the directory in search
of "content.xml" files, and aggregate them together. This makes
it easier to cobble together metadata from various places without creating
multiple metadata repositories 

- To allow for experimenting with groups that define filters, I added some
bits to the feature parser so that features can define extra filters on
their imports and includes. If you run a feature with filters through the
metadata generatory, they get turned into filters on the RequiredCapability.
This was simpler than hand-crafting filter-enabled groups manually._______________________________________________
