Re: [equinox-dev] scr, cm, and metatype

2017-01-27 Thread Thomas Watson 
Correct, Equinox EventAdmin uses a single thread for async event delivery.  See https://bugs.eclipse.org/bugs/show_bug.cgi?id=302729
 
That is pretty old bug.  Perhaps more is available in Java 8 to make this more simple to implement.  I have not put thought into this issue in a while though.  If you have some thoughts we can discuss in that bug report.

Thanks.   One follow up on EventAdmin.   I've read that the Equinox

anyone is interested in starting a branch to work on CM R7 in the mean

I did update the CM implementation to be CM spec version 1.5 a long 
time ago (3 years?).  OSGi R6 did not update the CM spec, if I recall 
correctly. The spec doc for OSGi R6 still lists CM spec at version 
1.5.  So from my perspective both of the CM and metatype Equinox impls 
are current with R6.


Ok, great...I must have been misinformed about the versions. Same for 
EventAdmin?


Also...I heard that there were some proposed CM/DS additions for R7. 
Are those to be in Equinox Oxygen or not likely?

As per bug [1], Equinox and Eclipse are moving to use Felix SCR v2.0.8
for Oxygen.

My understanding is that the Equinox ConfigAdmin and Metatype
implementations are rather old now...and don't support OSGi R6 versions
of those services.

Would it be possible to add Apache Felix of ConfigAdmin and
Metatype...versions that are at least R6 compatible...to Orbit?

The reason I ask is that a number of projects (e.g. ECF, Kura, Karaf,
others)...and our/their consumers...use DS+ConfigAdmin+Metatype all
three together, and having the Equinox versions of these services be so
old is a problem for them (especially since the spec enhancements over
last few years have been very significant.

Or, perhaps the right answer is to update these Equinox impls? Not sure.

Re: [equinox-dev] Eclipse Oxygen(4.7) M5 available

2017-01-27 Thread Todor Boev 
I noticed that in Oxygen M1, p2 was extended to support some generic
capabilities/requirements:
https://www.eclipse.org/eclipse/news/4.7/M1/#Equinox

I have two questions:
- Does this mean p2 now has a mechanism to support the general OSGi
capability/requirement model? (i.e. where a capability is a set of
properties and a requirement is an LDAP filter)
- Why are only "osgi.service" capabilities added? Should't there be also
"osgi.implementation" capabilities?

Regards
Todor
