[QGIS-Developer] QGIS logger plugin in core

[Tim Sutton]

Hi Nyall

Great to hear you are now more open to having this kind of logging in QGIS. Our budget and budgeted time for adding logging is pretty small (in the order to 1-2 days work). I suspect Richard has sunk quite a considerable amount of time into making his plugin so beautiful and functional. I think there is a good use case for building something more simple in core - a checkbox in settings to enable logging web requests, and a simple text output in the QgsLogMessage of each URL as it is called, along with the return code for the request. In my little universe, Richard's plugin would then still exist as the ‘Ferrari version, whilst out of the box our users have some basic tooling for debugging their services that are not playing nice. 

Regards

Tim

Nyall at the time (maybe others) was concerned about security implications of including a network logging tool in QGIS. We were wondering what specific security impacts could be expected (as opposed to for example installing Richard’s very nice logger plugin)[2]? In other words, is there really a good rationale not to port this to C++ and integrate into QGIS core? I think it is very broadly useful for anyone working with remote layers and trying to figure out why they are not loading...
