KnowledgeBaseDefinitionParser Should Always Create KnowledgeBaseOptionsConfiguration
------------------------------------------------------------------------------------
Key: JBRULES-2696
URL: https://jira.jboss.org/browse/JBRULES-2696
Project: Drools
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: All
Affects Versions: 5.1.1.FINAL
Environment: N/A
Reporter: Anatoly Polinsky

KnowledgeBaseOptionsConfiguration:
* <p>
* This class will automatically load default values from a number of places, accumulating properties from each location.
* This list of locations, in given priority is:
* System properties, home directory, working directory, META-INF/ of optionally provided classLoader
* META-INF/ of Thread.currentThread().getContextClassLoader() and META-INF/ of ClassLoader.getSystemClassLoader()
* </p>
Since this properties are only read when "RuleBaseConfiguration" ( KnowledgeBaseOptionsConfiguration implementor ) is constructed, this does not apply/work in case KnowledgeBase is defined via Spring without a <drools:configuration> due to the current sequence of events in "KnowledgeBaseDefinitionParser":
Element kbaseConf = DomUtils.getChildElementByTagName(element, "configuration");
if ( kbaseConf != null ) {
BeanDefinitionBuilder rbaseConfBuilder = BeanDefinitionBuilder.rootBeanDefinition( RuleBaseConfiguration.class );
// ... ... ...
factory.addPropertyValue( "conf", rbaseConfBuilder.getBeanDefinition() );
}
To fix it, RuleBaseConfiguration ( which implements KnowledgeBaseOptionsConfiguration ) should be created even though "<drools:configuration>" was not provided ( kbaseConf == null ):
Element kbaseConf = DomUtils.getChildElementByTagName(element, "configuration");
BeanDefinitionBuilder rbaseConfBuilder = BeanDefinitionBuilder.rootBeanDefinition( RuleBaseConfiguration.class );
if ( kbaseConf != null ) {
// ... ... ...
}
factory.addPropertyValue( "conf", rbaseConfBuilder.getBeanDefinition() );

[JBoss JIRA] Created: (JBRULES-2695) Spring "Drools Resources" Need to be Modular

Spring "Drools Resources" Need to be Modular
--------------------------------------------
Key: JBRULES-2695
URL: https://jira.jboss.org/browse/JBRULES-2695
Project: Drools
Issue Type: Feature Request
Security Level: Public (Everyone can see)
Components: All
Affects Versions: 5.1.1.FINAL
Environment: N/A
Reporter: Anatoly Polinsky
Assignee: Mark Proctor
When development is done by multiple teams, there should be a way to reference the resources in a modular way.
Here is how it is / can be done now ( which is BAD / not modular ):
<drools:kbase id="kbase">
<drools:resources>
<drools:resource type="DRF" source="classpath:org/drools/container/spring/team1_1.drf"/>
<drools:resource type="DRF" source="classpath:org/drools/container/spring/team1_2.drf"/>
<drools:resource type="DRF" source="classpath:org/drools/container/spring/team2_1.drf"/>
<drools:resource type="DRF" source="classpath:org/drools/container/spring/team2_2.drf"/>
<drools:resource ref="team3_1"/>
<drools:resource ref="team3_2"/>
</drools:resources>
</drools:kbase>
Since clients need to be aware of _every_ little artifact of individual team, and have to reimport all artifacts into a knowledge base one by one.
Here is a better way to do it:
<drools:kbase id="kbase">
<drools:resources ref="team1-resources"/>
<drools:resources ref="team2-resources"/>
<drools:resources ref="team3-resources"/>
</drools:kbase>
where individual team's config may look as:
(e.g. team 1):
<drools:resources id="team1-resources">
<drools:resource type="DRF" source="classpath:org/drools/container/spring/team1_1.drf"/>
<drools:resource type="DRF" source="classpath:org/drools/container/spring/team1_2.drf"/>
</drools:resources/>
------------------------------------------------------------------------------
Long story short:
"drools:resources" needs:
1. ID, to be able to ref to it
2. REF, to be able to ref to an ID
"drools:kbase" needs:
1. To optionally take a list of "drools:resources"
Thank you,

[JBoss JIRA] Created: (JBRULES-2814) DSL variable definition may create strange effects

DSL variable definition may create strange effects
--------------------------------------------------
Key: JBRULES-2814
URL: https://jira.jboss.org/browse/JBRULES-2814
Project: Drools
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: drools-compiler-DSL
Affects Versions: 5.1.1.FINAL
Reporter: Wolfgang Laun
Assignee: Mark Proctor
Fix For: 5.2.0.M1
The DSL parser accepts variable definitions
{name}
{name:pattern}
{name:q:pattern}
but also
{name:xyz:}
a) What *is* the purpose of "q"? It is tested in DSLMapWalker and influences what is used as a pattern, sometimes overriding a specified pattern: q pattern use-for-matching null null (.*?) null pattern pattern X null (.*?) X pattern pattern ENUM -- (.*?) DATE -- (.*?) BOOLEAN -- (.*?)
b) A "null" pattern is used for matching if {name:xyz:} is used.
I think the "q" is a relic and should be discarded. A ':' as delimiter in an area where any character is possible (as in a pattern) is bound to create ambiguities.
The "C" entry in the DSL below produces "null" in the pattern trying to match a condition; i.e., the string "null" is actually matched.
A, E, F result in pattern "(.*?)"
B, D use the pattern ("Boolean" or "Double", respectively)
DSL:
[when][]A {type} value=${type}: {type}()
[when][]B {type:Boolean} value=${type}: {type}()
[when][]C {type:xyz:} value=${type}: {type}()
[when][]D {type:xyz:Double} value=${type}: {type}()
[when][]E {type:ENUM:} value=${type}: {type}()
[when][]F {type:DATE:Float} value=${type}: {type}()
DSLR:
rule "rule 1"
when
A Integer value
B Boolean value
C Character value # fails; use "null" instead of Character to get a match
D Double value
E Enum value
F Float value
then
> System.out.println( "hello" );

Potential memory leak when rules are often reloaded

Hi!
There could be a small heapsize memory leak.
I encountered the problem when I tried to reload rules very often. The heap-size is permanently growing, eventhough the number of rules is constant! Since the heapsize grows very slowly, this leads to an OutOfMemoryError only, if I have a very large number of rules or if I reload the rules very often.
(code-example see below)
What do I mean by "reloading rules"? I add rules to an existing KnowledgeBase which is hold in memory. The rules come from an external source. For example, I add 500 rules into a KnowledgeBase (first run). Now, I redo this and add the same 500 rules again to the KnowledgeBase (2nd run). And so on. If I try this using a reduced heapsize of 64 MB, this works fine 71 times! But the 72nd time leads to an OutOfMemoryError, because there is no free heapsize left! It doesn't metter whether I remove the previously added rules first and add them afterwords again, or I directly add them.
Using a profiler, I can see, that the heap-consumption constandly increases!
The more rules I use, the less interations are possible (closley linearly). The more max. heapsize I use, the more iterations are possible (of course).
It seams like the Memory is hold by the RETE itself. The KnowledgeBase itself holds the references! If all references to the KnowledgeBase are deleted, the garbage collections frees the lost memory!
I also tried to use sequential mode. But there was no difference at all!
This happens with JRE 1.5 and JRE 1.6.
This also happens with the Drools 5.1.1 KnowledgeBase-Implemantion and the still in Drools 5 existing RuleBase-Implemention. But I didn't tested it yet with previous versions of Drools.
Why do I test this? We are building an application where rules will be created programmatically. There will be a large number of rules (some thousands) and rules can often change. The reload of rules which I tested here is something like a "simulation" of lots of rule changes.
Here is my example. For this example I used a simple Class called "RuleRepository" which has a static String-Array holding the rules as DRL-Strings. I also tried it with files in filesystem - no difference. See the RuleRepository-Class below. I post only 3 dummy-rules here - but that makes no difference. If someone wants to test with more rules, you can simply copy and rename them - or use your own rules!
