RightTupleList NPE with 6.1.0.Final
by Matteo Mortari
Ciao,
I'm using 6.1.0.Final - btw, thank you for this release!
I have an issue as sometimes I'm getting an NPE from the RightTupleList, as
documented in the snippet of stacktrace below. Unfortunately, I'm not able
to provide as I did in the past a reproducer, because this error occurs
only occasionally after the application has been running for quite some
time - this error does not happen with the rule unit tests suite.
Therefore I would like to ask you the following questions, please.
1. would the stacktrace below be enough for you to possibly identify the
kind of error which is happening in this case?
2. shall I go ahead and raise a JIRA just with this information? I've
checked on JIRA but couldn't find any "similar" issue for this case
Finally, if the answers are both "no", does it mean that the only way I
could provide an helpful feedback, is to log all the session incoming facts
indefinitely, so to later "craft" an log-replay reproducer; or would you
suggest another way I can do this more efficiently?
Thank you very much in advance for your feedback
Ciao

by LaKhI ReDdY!!!!!!!!!!!
Hi All,
Recently i have upgraded to drools guvnor 5.3.3.Final from Gurvnor 5.1.1. I
have exported the data and imported in 5.3.3.Final.
I am able to login to the application using default login using but not
able to login using SSO and getting "401 This user has no permissions
setup".
Can anybody suggest what needs to be done to avoid this error?

Conflict resolution strategy - before vs after Phreak impl
by mikerod
In version 5.x of Drools I see that it offered configurable conflict resolver
strategies. I also read a few different Drools documentation sources that
discussed varieties of "complex" conflict resolution strategies. One source
discussed a tiered implementation by the name of CompositeConflictResolver -
which was @ http://legacy.drools.codehaus.org/Conflict+Resolution.
We have been experimenting with uplifting from Drools v5.6.0.Final to a v6.x
version and we noted a fairly significant performance degradation /(a)/.
When digging into some rule logging,
we found that the issue was that our rule load order was not behaving well
in terms of conflict resolution. The "wrong" rule activations were chosen
to go first on the agenda, and this
was causing a lot of unnecessary/redundant "movement" within the Rete
network.
After reading through the documentation on conflict resolution strategies
and noting that it was configurable in Drools v5.x, I started thinking more
about the importance a conflict resolution strategy on performance. Digging
deeper, I believe Drools v5.6.0.Final uses
`org.drools.core.conflict.DepthConflictResolver` as the default resolver
(which is not the CompositeConflictResolver mentioned above interestingly).
In Drools v6.x (around v6.2.x I believe) with Phreak enabled, there is a
`org.drools.core.conflict.PhreakConflictResolver` that is used as the
default resolver.
This raises a few questions:
/1)/ With Phreak enabled, it looks like the conflict resolver is *not*
configurable anymore. I believe this is the case due to these lines
<https://github.com/droolsjbpm/drools/blob/master/drools-core/src/main/jav...>
. Why was this configuration options removed?
/2)/ The PhreakConflictResolver does not seem to be doing anything very
sophisticated now. I gather that it respects salience first, then falls
back to rule load order. I found this around these lines
<https://github.com/droolsjbpm/drools/blob/master/drools-core/src/main/jav...>
. Why was this implementation chosen? Is it discussed or documented
anywhere? Was it determined that this performs better than anything else or
that there is no significant difference either way? There are about 4
conflict resolver impls in the org.drools.core.conflict package. In Drools
v5.6.x I saw there were 10-11 of them in the similarly purposed
org.drools.conflict package.
/3)/ (related to /(2)/) Why was the default conflict resolution strategy
changed to PhreakConflictResolver from the DepthConflictResolver used in
v5.6.x? I do not think they are the same based on the source code, however,
I cannot say I fully understand all of the semantics of the
`Activation#getActivationNumber` used in the DepthConflictResolver.
I know that my perf issue /(a)/ noted above could be solved by using
salience, etc. I was wanting to avoid using salience where possible as it
leads to more fragile, less declarative systems. We were able to fix the
perf issue, by simply changing the rule load order anyways. My question is
not specifically asking how to deal with this perf issue. Instead I'm
asking about Drools choice of conflict resolution strategy in v6, as I have
listed in points /1-3/ above.
In the blog post @
http://blog.athico.com/2013/11/rip-rete-time-to-get-phreaky.html,
I think the sentence,
/"A simple heuristic, based on the rule most likely to result in firings, is
used to select the next rule for evaluation; this delays the evaluation and
firing of the other rules."/
is the only thing I see on the topic of conflict resolution (at least I
think it is). I understand the parts about unlinked and linked rules,
however, when the agenda is populated by multiple activations of the same
salience, that's when things get interesting from the point of view of the
topic discussed here.
I appreciate any feedback with regards to this.

Drools Fusion (CEP) & clustering
by Ephemeris Lappis
Hello.
I'm looking for some reference architecture for Drools CEP clustering.
If I'm not wrong, the Drools 6.x documentation doesn't explain how to set a
clustered environment to handle events processing. For example, how can we
ensure load distribution, time windows control, state integrity, etc.,
running several engines ?
Any information about that ?
Thanks in advance.
Regards.

Api changes from drools 5.0.1 to 6.0.1??
by techy_bolek
We are upgrading our application from drools 5.0.1 to drools 6.0.1 Final. I
noticed there are significant API changes. Many classes that used to be in
org.drools appear to be now in org.drools.core. Also, some classes appear to
be gone: DebugRuleFlowEventListener, RuleAgent.
My question is: is there a documentation somewhere explaining the API
differences between the two versions?
If there is no such documentation - can anyone advise what to do about
DebugRuleFlowEventListener and RuleAgent?
Thanks, Thomas
