Until now mouse right-click could only select and deselect the highlighted
feature to "lock" vertex tool (and numerical editor) to it, so that it is
easier to focus only on editing of the particular feature. It was however
still difficult to pick the right feature in case there were multiple
features in one location or very close to each other. This is now solved
by the fact that repeated right button clicks will loop through the editable
features. So if there are two features in one location (A, B) then repeated
right-clicks will select: A - B - nothing - A - B - nothing ...
We no longer require the seperate CRS parameter, because the extent
parameter contains the CRS information itself. This means the algorithm
is simplified to just picking the layer and drawing the desired area
on the canvas.
generated filename for outputs
Previously they were just echoing the input parameter value,
which isn't always a string and accordingly was broken for
temporary outputs. This caused models to break when the output
of a GDAL algorithm was used in a subsequent model step.
The "comments" PR 8831 added support for postgres only
(and broke all the others backends).
I'd be in favor of a revert of the whole original PR but
this patch restores functionality and could be an acceptable
temporary fix until the comments PR is reworked in a more
maintainable and elegant way.
Fixes#21151 btw
When a new QgsAbstractGeometry is set on a geometry object, the previous child is deleted.
If the previous object was constructed by Python, it's wrapper will still be alive for
as long as the QgsGeometry is alive. If a new QgsAbstractGeometry is constructed at the same
memory address as the old one, the wrapper will be reused with wrong type (and other)
information, leading to all kind of weird issues.

Remove responsibility for credentials mutex locking from external
callers and handle appropriate locks internally. This allows the
mutex lock to be much "tighter" and avoids deadlocks when
credentials are requested while an existing credentials dialog
is being shown.
(No mutex is required protecting the credentials dialog itself
as this is ALWAYS shown in the main thread)
Fixes#20826
