Re: [QGIS-Developer] Catch PostgreSQL logs in pyqgis
Hi Matteo, https://api.qgis.org/api/master/classQgsDatabaseQueryLog.html does have appropriate signals (queryFinished and queryStarted, both include the query) but it looks like they are not documented in the Python API https://qgis.org/pyqgis/master/core/QgsDatabaseQueryLog.html It *looks* like they are exposed though. So try def do_something_with(query): ... query_log = QgsApplication.databaseQueryLog() query_log.queryFinished.connect(do_something_with) If that does not work, maybe the debugging panel itself has a signal you can connect to as a hacky workaround.

Re: [QGIS-Developer] Ubuntu GIS repo with new gdal, LERC and ZSTD support?

Debian unstable has GDAL 3.8.4 with LERC support (but is not suited for jammy). We have QGIS builds of the release branches and master for both of them (ubuntugis and debian just the LTR branch).

Re: [QGIS-Developer] Ubuntu GIS repo with new gdal, LERC and ZSTD support?
#osgeolive is a project of OSGeo dot org, and is part of the developer chain that builds UbuntuGIS https://live.osgeo.org An experimental build of new GDAL and QGIS can be found here https://launchpad.net/~ubuntugis/+archive/ubuntu/ubuntugis-experimental/+packages This is fresh-paint new and needs some testing. A preferred way to test is to enable the UbuntuGIS repo, and then this repo on top of that. If people have the skills, please try and report back to UbuntuGIS mailing list. apt source => deb http://ppa.launchpad.net/osgeolive/release-16.0/ubuntu jammy main https://lists.osgeo.org/mailman/listinfo/ubuntu hth- ##-- Brian M Hamlin / MAPLABS / OSGeoLive PSC On 3/4/24 08:51, Andreas Neumann via QGIS-Developer wrote: Hi, I am wondering if there is a ubuntu (or debian) package repository available with a relatively new gdal, LERC and ZSTD support?

[QGIS-Developer] Catch PostgreSQL logs in pyqgis

[QGIS-Developer] QGIS & field computer and unauthorized DB structure change
Hello everyone, I have noticed the following: if I have read and write access (DML) to a PostgreSQL table, but no access to structure changes (DDL), then I can, for example, add new columns with the field calculator and fill them with results. Everything seems to run normally, I do not get a warning that I am not allowed to change the structure, the results generated in the field calculator are OK. After saving, all new columns including the data are gone. Can a corresponding preliminary check with warning be added here please? If a new column is explicitly added, a message appears whose content does not match the situation. "Could not add field 'Test' of type 'text'. Is the field name unique?“ A warning regarding missing authorizations for DB structure changes would be better. As far as I know, there is no QGIS ticket or change request(https://github.com/qgis/QGIS/issues) to improve the user guidance for these two cases. There are currently two relevant sections in the error messages(https://github.com/qgis/QGIS/blob/master/i18n/qgis_de.ts). Failed to add field '%1' of type '%2'. Is the field name unique? Could not add field '%1' of type '%2'. Is the field name unique? Failed to add field '%1' of type '%2'. Is the field name unique? Could not add field '%1' of type '%2'. Is the field name unique? Many thanks in advance.

Re: [QGIS-Developer] QgsGeometry's .get() and segfaults
Hi,
Calling get() means that you get a reference of the QgsAbstractGeometry used by
the
QgsGeometry object, but the QgsGeometry object (g) is still the
ownership of the QgsAbstractGeometry object (g_geom).
So, if you delete your QgsGeometry (g) you delete the owned
QgsAbstractGeometry (g_geom). And you would get quite the same issue if you
wanted to delete g_geom.
Best is to use constGet() and clone() your returned QgsAbstractGeometry
if you want to manipulate it independantly from its original QgsGeometry
owner.
Regarding detach(), it's because of a design pattern called "Implicit
Data Sharing" or "copy on write". When we copy a QgsGeometry, both objects are,
under the hood,
referencing the same memory object (QgsGeometryPrivate d). When you end up
modifying one of the object (moveVertex for
instance), you detach the modified object so the two are no longer
sharing the memory private object (hence the name "copy on write").
That's what happen when we call get(), we need to detach so other
QgsGeometry object would not be impacted by later modification of the
non-const returned object.
Hope that makes sense :)
