Summary: An <include> in an included file leads to out of memory
Product: logback-core
Version: unspecified
Platform: All
OS/Version: All
Status: NEW
Severity: blocker
Priority: P1
Component: Joran
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
Situation: 3 configuration files A.xml, B.xml and C.xml
A includes B and B includes C
This leads Joran to run into out of memory.
The reason is in class ch.qos.logback.core.joran.action.IncludeAction
The begin() method fills the instance variable recoder with events and adds
them to the global list. But since there is only one instance of IncludeAction
it adds the already added events from the first include a second time at the
second include event. This leads to an almost endless loop.
A not that severe effect is that if a single file contains multiple includes it
executes the first include as often as the total number of includes is.
To solve this for me clearing the event list at the end of the begin method
worked well:
public void begin(InterpretationContext ec, String name, Attributes
attributes)
throws ActionException {
...
ec.getJoranInterpreter().addEvents(recorder.saxEventList);
// This is my fix
recorder.saxEventList.clear();
}
