[QGIS-Developer] A new way to build QGIS and all its dependencies from scratch in Linux and MacOS

Hi all. I am a volunteer contributor for the software project [Spack]( https://github.com/spack), an HPC package manager. Using this tool, it is possible to build QGIS and all of its direct and indirect dependencies from scratch using a single line of command as shown below. I thought this might

[QGIS-Developer] OSGeo4W Qt and OpenSSL versions

Hi, Comment mostly for Jürgen (and Windows devs/users)... I recommend OSGeo4W's Qt packages be updated to 5.12.4 or latest LTR, specifically for this OpenSSL v1.1.1 reason: https://www.qt.io/blog/2019/06/17/qt-5-12-4-released-support-openssl-1-1-1 I think it is a security concern to rely upon

Re: [QGIS-Developer] QGIS unstable on debian testing

I've already tested with shapely and it was working as expected. But the shapely installed with pip install shapely has geos 3.8.0 and not geos 3.8.1 installed by apt. I now built geos 3.8.0 from source and the rest of the chain (proj 7.0.0, libgeotiff master, libspatialite from fossil, gdal

[QGIS-Developer] Experience with coverage.py?

Hi all, has someone by any chance been trying or even successfully using `coverage.py` (1) inside QGIS' Python code and/or plugins and could share some experience? For me, it works, sometimes, with plenty of edge cases ... I am basically running into all sorts of wired issues - presumably due to

Re: [QGIS-Developer] QGIS unstable on debian testing

Hi uclaros, Can you check just GEOS without QGIS? Does this works? from shapely import wkt a = wkt.loads('Polygon ((0 0, 1 1, 1 0, 0 0))') b = wkt.loads('Point (42 0)') print(a.intersection(b)) My answer is just: POINT EMPTY Best regards, On 14/04/20 14:15, uclaros wrote: > Thanks for the

Re: [QGIS-Developer] QGIS unstable on debian testing

Thanks for the reply, the python code was just an easy way to trigger the crash. The problem is not python related, it's reproducible on a fresh debian testing vm, fully upgraded, ie proj 7.0.0, gdal 3.4, geos 3.8.1. The issue does not exist on debian stable, maybe your ubuntu is based on the

Re: [QGIS-Developer] QGIS unstable on debian testing

Hi uclaros, No crash here, running your PyQGIS code, on Ubuntu. Even if you compile Proj 6.3.1 + GDAL 3.x + QGIS properly, we can have problems with Python. For example, I recently changed to Python 3.7 and I had to: sudo pip3 install pyproj --no-binary pyproj sudo pip3 install owslib and

Re: [QGIS-Developer] QGIS unstable on debian testing

Part of my problems seem to be caused by the fact that intersections between a polygon or linestring and a point cause QGIS to crash... eg. the following python code: QgsGeometry.fromWkt('Polygon ((0 0, 1 1, 1 0, 0 0))').intersection(QgsGeometry.fromWkt('Point (42 0)')) -- Sent from:

Hi Arnaud, I explored the QgsProcessingFeatureBasedAlgorithm but unfortunately is not the case of what I'm looking for. From what I understood QgsProcessingFeatureBasedAlgorithm is the class to use when the algorithm performs "feature-by-feature" operations like buffers. In my case I would like
