* - I found out that we finally have problems with the (somewhat recursive)Rainer Gerhards2007-08-031-16/+74
| | | | | | | | | | | | | | | | | | | | | | | | call to logerror() that many of the modules do. I have not tried it, but I think things will become wild when we compile without pthread support. Threading prevents full recursion, so we have not seen any bad effects so far. However, the problems that I experienced in ommysl (that caused me to re-structure startWorker()) are actually rooted in this issue. I first thought to fix it via a module interace, but I now came to the conclusion that it is not more effort and much cleaner to do an internal error buffering class. This is implemented in errbuf.c/h. - I just noticed that this is not actually an error buf, but the core of an input module for all internal messages. As such, I implement it now as iminternal.c/h. Of course, there is no input module interface yet designed, but that doesn't matter. Worst-case, I need to re-write the im, best case I can use the im (at least partly) to define the interface. - added a few functions to the linkedlist class - error messages during startup are now buffered - so we do no longer need to think about how emergency logging might work. Actually, these are logged to whatever is instatiated in the log file. This enhances the chance that we will be able to drop the error message somewhere it is seen.
