Sounds like a sensible plan, but generally I'd recommend erring on the side of restrictiveness and require the user to explicitly state when they want support for a more unusual feature. The reason for this is people new to drools should be strongly encouraged not to do potentially undesirable things, it's much easier to choose to enable things you actually want than to choose to restrict behaviours you have no knowledge of!
Thomas From: [email protected] [mailto:[email protected]] On Behalf Of Edson Tirelli Sent: 25 August 2011 01:03 To: Rules Dev List Subject: Re: [rules-dev] PackageBuilder Warnings question Hi Mikael, One idea would be to define severities for compilation messages... could be 1..3, could be INFO, WARN, ERROR, etc. Each problem would have a default priority and in an ideal world, the user could override this priority (like you can do it in eclipse). So, for instance, a rule update could have a default severity of INFO, but if the user does not use dynamic rule updates, he would be able to define it as severity ERROR. ERRORS would always prevent execution, while warnings and infos would be reported, but not prevent usage. This is my opinion would be a great step forward compared to what we have today. What do you think? Thanks, Edson 2011/8/24 Mikael Lönneberg <[email protected]<mailto:[email protected]>> Hi I'm currently working on an implementation of a new type of problem type namely Warnings, to solve the following JIRA's: JBRULES-3124, JBRULES-3063, JBRULES-2730 One of the JIRA's deal with the detection of duplicate rules and another with detection of duplicate functions. The question I have is in regards to this is, the current implementation allows for rules and functions to be overridden by functions and rules defined in different .drl files. In order to not break backwards compatibility and allow people to continue with this behavior we could just create a warning for these types of issues which is reported through a new getProblems(ProblemType... problemTypes) to get the problem types you are interested in, we will leave the legacy method getErrors() for backward compatibility. Another approach or complementary approach is to for certain types of these Warnings configure the compiler to be more or less strict, which in turn would switch the Type of these issues from Warning to Error. Is this something that's desirable or would it be sufficient to just report these issues as warnings and leave the responsibility to the user to halt execution if certain Warnings exists?
