Dominik Psenner commented on LOG4NET-394:
-----------------------------------------
What do you expect to happen if you write this somewhere in your application:
ILog logger;
[...]
logger.DebugExt(null);
or
ILog logger;
[...]
logger.DebugExt(() => 123/0);
As I see it, log4net should not silently ignore erroneous code which is part of
a lambda expression since log4net is not responsible of the lambda expression
just alike log4net is not responsible if someone writes this:
ILog logger;
logger.Debug(123/0);
> Lambda-based ILog-Extensions should catch errors

> Key: LOG4NET-394
> URL: https://issues.apache.org/jira/browse/LOG4NET-394
> Project: Log4net
> Issue Type: Improvement
> Components: Core
> Affects Versions: 1.2.12
> Reporter: Gian Marco Gherardi
> Priority: Minor
>
> The new lambda syntax introduced with LOG4NET-290 allow wrapping log related
> code in a lambda to be executed only if necessary. In the log4net spirit of
> being a reliable logging system (see
> http://logging.apache.org/log4net/release/faq.html) also the log related code
> contained in the lambda should not block application by throwing exception
> and so the lambda execution shluld be wrapped in a try...catch
