JIRA priorities
by Mircea Markus
I'd like a way to see what are the JIRAs that are absolutely critical for a release (i.e. won't release without them in) and the ones that won't delay the release, but would be rolled over to next release.
I'm thinking to mark these JIRAs as:
- Critical if they must make it for the Final
- Blocker if they must make it for the next release (might be an Alpha)
What do people think?
Cheers,

ISPN-2314 fix looks fishy
by Galder Zamarreño
Hi guys,
Having briefly investigated https://issues.jboss.org/browse/ISPN-2314, I consider the fix (https://github.com/infinispan/infinispan/pull/1318) to be rather fishy.
Sure it works, but it masks the fact that the order in which things are started has changed (This IMO seems to be the result of http://issues.jboss.org/browse/ISPN-2256).
Not only that, but the fact that you have to modify both the component registry and the configuration makes me think that there're situations where the configuration changes are applied, and others where it's not (hence why you have to change the component registry).
So, can we please stop and try to understand what really is happening here? I was expecting Mircea to have a look into a fix for this since it looks related to cache start order.
Personally, I don't really see why the lifecycle manager has to mess up with the component registry. Changes to the configuration were 'enough' (until 2256) and I don't see why that should change.
Cheers,

Re: [infinispan-dev] Issue with cache blocks for local read-only cache
by Manik Surtani
Agreed.
This locking appears to be in the 2LC integration code to guard a local collection though - there must be better, non-blocking ways to guard this - if it is needed at all for RO entities.

ISPN-2296 Query projections
by Marko Lukša
Hey Sanne and others,
before I send a pull request, can you review my impl of ISPN-2296 at
https://github.com/luksa/infinispan/compare/ISPN-2296. I'd like your
input on this before implementing this on clustered queries.
Basically here's what I did:
Extracted an interface (QueryResultLoader - any ideas for a better
name?) from EntityLoader and introduced ProjectionLoader. This took care
of projection of actual fields.
For projecting the cache key, I introduced ProjectionConverter, which
translates the fields passed to cacheQuery.projection(fields) into
fields that hsearch can deal with (currently, only
ispn.ProjectionConstants.KEY is replaced with
hsearch.ProjectionConstants.ID). The converter is then also used to
convert the actual values returned by hsearch (for
cacheQuery.projection(ProjectionConstants.KEY), it converts the id
returned by hsearch into the cache key).
Just for completeness, besides introducing ispn.PC.KEY, I also added
PC.VALUE, which is equivalent to hsearch.PC.THIS.

X-Site: Site Unreachable vs. Site Down
by Erik Salter
Hi all,
For the X-Site pull request, Bela, Mircea and I had a design review. One of
the items that came up was the ability to mark a site as being down
where a site has been unreachable for a period of time. This mostly applies
to the synchronous replication case where the backup failure policy has been
configured as FAIL, i.e:
<namedCache name="importantCache">
<sites>
<backups>
<backup site="NYC" strategy="SYNC" backupFailurePolicy="FAIL" timeout="16000
0"/>
</backups>
</sites>
</namedCache>
The current implementation would be to fail all requests until a SA realizes
the site is offline and mark it through a JMX operation (provided in this
release?). Since I cannot afford a 100% failure rate until somebody gets
called, I think we need to take it a step further and add an element to mark
a site as offline after a period of time. (Note, though, a site can only
be brought back online manually.)
Mircea talked about adding an element in the configuration for a custom
callback implementation. However, I think this is useful enough -- not only
for me -- but for other ISPN/JDG users as well. (Not to mention we can't
add configuration for callbacks)
Comments?
Thanks,
Erik
