Description
In Current Master, when for example calling this wfs:
https://geodata.nationaalgeoregister.nl/bag/wfs?request=GetCapabilities
(epsg:28992, please zoom in enough to only show a couple of kilometres)
Sometimes (I think initiated by an 'abort') you will see a lot of:
ERROR: Opening of authentication db FAILED
Messages in the messagebar (see screenshot),
Debug output below.
Note that this IS not an authenticated service (it is public).
Not sure if it is really about the auth db, or maybe about the WFS-cache??? db?
Note that I'm behind a http-proxy here, not sure if that can be part of the issue.

Fix authentication database connections
Fixes the authentication database cannot be opened in some circumstances.
We need to ensure that the pooled database connection is removed
immediately on thread finalisation and cannot defer this until
the main thread event loop runs.

Richard, the reason you are seeing this is because the WFS layer is served through an HTTPS (i.e. secure/encrypted) connection. HTTPS connections trigger a call to the authentication manager (to seek e.g. custom certificates).
I'm also seeing this for XYZ layers. A band aid to avoid a flood of message bar items has been submitted: https://github.com/qgis/QGIS/pull/8372

Ok, thanks Mathieu. But limiting the amount of msg's is/should indeed a temporal fix isn't it?
I wonder now why QGIS cannot actually open a/the db anymore?
Because I (think) I do not have one? We then can maybe create an empty one in the profile?
Or is it locked? We should think of solution for that then if possible?
Anyway thanks for this fix already!

the proxy settings are normally stored in the authentication DB because they may contain creadentials with passwords.
You should try to understand why the authentication DB cannot be opened.

as spotted by Mathieu Pellerin the error is rised due to this PR 69dab87d4a254bca9c3b22ae0dc07af3f22c6a1a. that is necessary after the adoption of qt5.11

Hi Paolo,
We are talking about qgis-auth.db isn't it? File looks normal to me. I can (during the time QGIS is complaining) open it with sqlitebrowser.
The Qt tab in Log Messages shows:
2018-10-30T09:32:07 WARNING QSqlDatabasePrivate::database: requested database does not belong to the calling thread.
2018-10-30T09:32:07 WARNING QSqlQuery::prepare: database not open
At that time the Messages tab show:
2018-10-30T09:32:07 CRITICAL Authentication Manager : Opening of authentication db FAILED
2018-10-30T09:32:07 WARNING Authentication Manager : Auth db query exec() FAILED
To me here (I'm behind the proxy now) it is easy reproducible:
- create a really fresh profile
- add proxy network settings
- add WMST layer (eg https://geodata.nationaalgeoregister.nl/bag/wfs?request=GetCapabilitiesP
- add one if its (epgs:28992) layers
- nothing wrong all requests fine, no errors
- add WFS connection, eg https://geodata.nationaalgeoregister.nl/bag/wfs?request=GetCapabilities
- without even adding the layer, QGIS starts spitting out the stream of warnigs and errors
Creating a new project and adding the wmst layer again: silence...
Add one of the layers from the wfs service (zoom in a LOT) and immidiatly you see in Qt tab:
2018-10-30T09:43:01 CRITICAL Authentication Manager : Opening of authentication db FAILED
2018-10-30T09:43:01 WARNING Authentication Manager : Auth db query exec() FAILED
I have the feeling that sometimes I do not even have to add the wfs, but it happens also when only working with the wmts layer...?
