Similarly for models: "Get models from on-line scripts collection" seems to download something but no models appear in the toolbox. (No visible error message)

Hi Anita,

looking into debug:

At least the list of scripts is downloaded:

https://raw.githubusercontent.com/qgis/QGIS-Processing/master/scripts/list.txt

And if I select on script it is downloaded too:
src/core/qgsnetworkaccessmanager.cpp: 96: (queryProxy) [16ms] using fallback proxy for https://raw.githubusercontent.com/qgis/QGIS-Processing/master/scripts/realcentroid_algorithm.py
src/core/qgsnetworkaccessmanager.cpp: 223: (createRequest) [0ms] Created [reply:55d45919ee60]
src/core/qgsnetworkaccessmanager.cpp: 185: (createRequest) [190ms] Adding trusted CA certs to request
src/core/qgsnetworkaccessmanager.cpp: 96: (queryProxy) [3ms] using fallback proxy for https://raw.githubusercontent.com/qgis/QGIS-Processing/master/scripts/realcentroid_algorithm.py.help

But trying to run:

This script has a syntax errors. Problem with line: ##output=output vector

And then removing that line still not working:

Algorithm 'Real centroid' starting...
Input parameters: { 'poly' : '/home/richard/geodata/provincies.shp' }

Traceback (most recent call last): File "/home/richard/bin/qgis_all/master/debug/share/qgis/python/plugins/processing/script/ScriptAlgorithm.py", line 261, in processAlgorithm exec((self.cleaned_script), self.ns) File "", line 8, in ImportError: cannot import name 'VectorWriter'

Execution failed after 0.14 seconds

I think that maybe the interface for the scripts is changed, so the authors should either fix the scripts, OR we should remove them from the master branche of QGIS (they are working for 2.18 isn't it?)

Yes, the scripts work in 2.18 but something has changed in master and I cannot find any documentation.

There is nothing wring with Processing itself, it works. The problem is that scripts and models in the online repository were not updated to QGIS 3. That's why they are not listed in the Processing toolbox after downloading. Scripts/models authors should update their code to API changes similarly to the plugins.

If the scripts were updated, then they would be broken in 2.18, right? Or is there some logic in place that fetches the correct version?

As I can see there is no logic to handle multiple versions. And IMHO we should remove code for managing online repo from Processing completely in favour of Resource Sharing plugin.

+1 for removing the "get from on-line scripts/models collection" code
