[QGIS-Developer] Documentation of QGIS3.ini structure/schema?

[Richard Duivenvoorde]

Hi Hannes,

Not sure if it is documented, and not sure IF they should be at different places.

But one explanation, IF this is an old profile and you are running master/own compiled QGIS's, could be that a new Settings regime has been introduced recently, which changed the 'keys' of (almost all) settings. Denis can tell you the exact details.

It could be that you have multiple configurations, because of 'intermediate' and old settings... I do not think the new code cleans up old settings (but it SAVES them).

I've at a certain moment replaced/refreshed some of my profiles because of settings troubles...

Regards,

Richard Duivenvoorde

Looking at a naturally grown profile I found 5 different places in which configuration is stored for one single WFS connection, mostly redundantly and I wonder if this is documented somewhere?
