'last modified' and 'created by' attributes for a asset showing wrong userid in Guvnor 5.4.0.final
by vadlam
Has anyone come across this scenario ?
In Guvnor 5.4.0.final, when user1 initially logs in and updates a asset(
saves and closes it, logs out ) , subsequent asset updates for same asset or
different asset by user2 still show as done by user1 which is incorrect.
updates done by user2 need to be shown as Last modified by user2 and not
user1 .
In the log file extract shown below, though the changes were done by user2 ,
it shows in the logs as well as Guvnor asset attributes screen as done by
user1 which is incorrect.
This is even though user1 and user2 logged out and logged in a couple of
times to see if Guvnor was holding on to an asset .

Getting deadlock-like thread state
by Bojan Janisch
Hey drools users,
I'm running drools multiple times in parallel with ECJ (genetic algorithm framework). Also I'm running ECJ multiple times in parallel (evaluation purpose).
But each time I want to run ECJ, after an unspecific time, one thread is running infinite long while ECJ waits for it to finish. Additionally to this my
working memory is steadily growing while hanging in this deadlock-like state, though this might not be due to drools. This goes on until I get an gc out of
memory exception.
I've created a threaddump which always looks so:

To my Programm:
Rules are generated in parallel and for each rule, a new KnowledgeBase, KnowledgeBuilder and StatefulKnowledgeSession is created.
Objects are inserted into the session and the rule is fired. The session will be disposed after no facts matches my rule or 1000
conclusions are fired.
I've searched the net for a similar problem, but with no success. Does someone know why Drools get into such a thread state and
how to get out of it?
I appreciate any help.

Change Notification doesn't work with eval(true) in one of the rules
by Sammi
All the rules defined in a single DRL were running fine until one day we
added eval(manager.isEnabledSomeSettings()) into one of the rule in drl,
which causing an issue for change update on the fly (see below error
stacks). When we changed that eval to Boolean(this == Boolean.TRUE) from
manager.isEnabledSomeSettings() then the change notification getting back to
work properly. Any ideas?

Importing functionS from another drl in 5.5.0
by Sonata
If you have defined functions in a drl, in order to use those functions in
another drl of a different package, you will have to import each individual
function, like
package A;
function void func1 () {
System.out.println("Hello");
}
function void func2 () {
System.out.println("There");
}
pacakge B;
import function A.func1.func1;
import function A.func2.func2;
rule Test
when
then func1(); func2(); end
Is there any way to do something like import function A.*; in Drools 5.5.0
to use all the functions defined in another drl?
Thank you

DRL always posting the format as txt instead of model.drl
by learnbrms
Hi,
I am using the following code to post or update the DRL using ATOM. But I am
seeing that DRL is always posted and displayed in Guvnor as .txt
(Format:txt) instead of Format:model.drl.
public int createUpdateTextAsset(String assetLoc, String ruleName, String
ruleDescription, String fileToUpload, String requestMethod)
{
System.out.println("--------Begin createUpdateTextAsset ----------");
System.out.println("assetLoc "+assetLoc+"\nruleName
"+ruleName+"\nruleDescription "+ruleDescription+"\nfileToUpload
"+fileToUpload+"\nrequestMethod "+requestMethod);
String authCode = user+":"+password;
StringBuilder content = null;
Scanner scanner = null;
client = WebClient.create(baseURL);
try
{ File f = new File(fileToUpload);
content = new StringBuilder();
String NL = System.getProperty("line.separator");
scanner = new Scanner(new FileInputStream(f));
while (scanner.hasNextLine()) {
content.append(scanner.nextLine() + NL);
}
String ruleContent=content.toString();
String atom = "";
Response response = null;
String authString = "";
authString = "Basic " + org.apache.cxf.common.util.Base64Utility
.encode(authCode.getBytes());
client.header("Authorization", authString);
atom = "<entry xmlns=\"http://www.w3.org/2005/Atom\"
xml:base=\"";
atom += assetLoc;
atom += "\"><title type=\"text\">";
atom += ruleName;
atom += "</title><summary type=\"text\">";
atom += ruleDescription;
atom += "</summary>";
atom +="<metadata>";
atom +="<property name=\"archived\" value=\"false\" />";
atom +="<property name=\"rule-format\" value=\"model.drl\"/>";
atom +="</metadata>";
atom += "<content type=\"application/xml\">";
atom += ruleContent;
atom += "</content></entry>";
System.out.println("Atom :"+atom);
if(requestMethod=="POST"){
response = client.path(assetLoc).type(MediaType.APPLICATION_ATOM_XML)
.header("slug", ruleName+".drl")
.post(atom);
}else{
response = client.path(assetLoc).type(MediaType.APPLICATION_ATOM_XML)
.put(atom);
}
System.out.println("--------End createUpdateTextAsset ----------status

return response.getStatus();
