But my point is that if obtaining the StackFrame and Class could be done so quickly that it wouldn’t add any noticeable overhead we could do that in every Logger.info, debug, etc. call. If we could just get the stack frame index so that we could obtain the StackFrame and Class later by using the index that would be even better since we would only be creating the StackFrame, etc if it is really required.
Working with stack frame indexes is at best fragile, unless you make a snapshot of the stack first and only used the index in relation to that snapshot. So I wouldn't recommend going that way. Furthermore to obtain such an index you would need to count the frames - which would mean walking the whole stack. I'm still not sure I understand why an appender would call Logger.log. That sounds like a recipe for stack overflow or endless ping pong loops. I understand that could theoretically happen but then the appender would need to protect itself against 'logging while logging'. Or am I misunderstanding? best regards, -- daniel
