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
With recent changes in QgsNetworkAccessManager this should be
safe to resurrect (fingers crossed!). Also simplify code a lot,
because now QgsNetworkAccessManager handles waking the worker
thread after the auth request is handled.
Add a lot more tests
races and crashes when auth requests occur in non-main thread
Like the recent SSL error handling, this commit abstracts out
the network authentication handling into a thread safe approach.
Brings back QGIS 2.18's ability to directly convert a Processing model
to an equivalent Processing Python script algorithm, correctly
updated and working in the 3.x API.
Available from the model dialog, and from the right-click context
menu on an existing model.

- fix parameter can get converted to plain number parameter after edits
- allow parameter to be linked to parent parameters, so that the
correct distance unit and choices are shown for the parameter
