blocklisted and hidden from the QGIS interface, e.g. it is an internal
detail only (or sidecar file) and shouldn't be shown in things like the
browser panel
And adds blocklists for .aux.xml, .shp.xml and .tif.xml files for
the ogr/gdal providers
for a URI to better handle ties, add direct method to determine
whether a particular provider should defer handling of a certain
URI to another (better equipped) provider
The trust flag at the projetc level is only used to read vector layer extent from xml, not from provider.
This flag was not available at the vector layer and data provider level.
We propose a new QgsMapLayer reading flag to propagate the trust layer metadata prohect's read flag an d a new provider options to trust datasource config.
Trusting the datasource config means that the provider can use estimated metadata, the primary key is unique and the detectable geometry type and srid are the same as the requested.
This is the implementation of the new DB connections API (grant proposal 2019).
Summary
The new API makes it available to QGIS core a new interface for provider connections and will allow to:
replace the provider specific QgsSettings management in QGIS4 (save/load connections from the settings) NOT IN SCOPE FOR NOW.
provide a unified API for common operations on DB connections:
executeSql and get the results
list tables names and properties and schemas
create a new vector table (no rasters for now)
create/rename/drop schemas and tables
vacuum
....
- grass data item provider fixes
- removed QgsProviderMetadata constructor (with std::function / PyObject) due to sip errors (api break)
- reverted DataCapability move to Qgis - back to QgsDataProvider (avoiding api breaks)
- WidgetMode enum documentation
- sipify monkey patching fix
- renamed WidgetMode's "None" to "Normal" value - in python None has special meaning (api break)
For the c++ api dox this expands to "\c nullptr" (the
\c directive indicates a code literal value), and for sipify/Python
it expands to ``None`` (`` is sphinx annotation for literal values)
Makes for nicer dox for both c++ and Python!
