Questions tagged [error-log]

The Error Log view captures all the warnings and errors logged by plug-ins.

The error logging system aims at making logging much more flexible at run time. The decision to log or not is highly configurable, and controllable while running. One should be able to enable or disable messages based on source file, class, function, and level. This enables easier debugging as developers can turn messages on as needed to see what is going on without recompiling or restarting. It will also help in that messages which are no longer useful can be disabled and so not flood the logs.

A secondary goal is the regularization of all messages so that the class and function are printed out automatically at the start of all messages. This greatly aids in both find the source of messages, and in filtering log files.

Of course, if all message logging code is to be compiled in, another goal must be to make skipping suppressed log messages as efficient as possible.
