g.extension failing in GRASS 7.8.5

[micha-silver]

Describe the bug Running g.extension to add an add-on fails with:

micha@RMS:~$ g.extension v.surf.tps
Fetching <v.surf.tps> from GRASS GIS Addons repository (be patient)...
svn: E170000: URL 'https://github.com/OSGeo/grass-addons/trunk/grass7/vector/v.surf.tps' doesn't exist
ERROR: GRASS Addons <v.surf.tps> not found
micha@RMS:~$ g.version
GRASS 7.8.5 (2020)

See also: https://gis.stackexchange.com/questions/408345/installing-grass-extension-modules-on-macos-and-linux

To Reproduce Steps to reproduce the behavior:

1. g.extension -l works as expected
2. g.extension fails

Expected behavior Download addon script from the correct github path.

System description (please complete the following information):

• Operating System: Linux, .
• GRASS GIS version [e.g. 7.8.5]

Additional context Currently in the g.extension python script, the function: def resolve_source_code(url=None, name=None, branch=None): defaults to the git path grass-addons/trunk/:

   if not url and name:
        module_class = get_module_class_name(name)
        # note: 'trunk' is required to make URL usable for 'svn export' call
        git_url = 'https://github.com/OSGeo/grass-addons/trunk/' \
                   'grass{version}/{module_class}/{module_name}' \
                   .format(version=version[0],
                           module_class=module_class, module_name=name)
        # trac_url = 'https://trac.osgeo.org/grass/browser/grass-addons/' \
        #            'grass{version}/{module_class}/{module_name}?format=zip' \
        #            .format(version=version[0],
        #                    module_class=module_class, module_name=name)
        # return 'official', trac_url
        return 'official', git_url

Perhaps this is the cause of the error?

See: https://grass.osgeo.org/news/2021_08_01_g_extension_currently_not_working/

And: https://github.com/OSGeo/grass/pull/1762

The issue is addressed and updated binaries are hopefully available soon (the RC needs to be aprooved to be final).

Thanks!

That means users who installed GRASS through their distro's package manager have to wait until an updated version is available with their distro's package manager? Until then (can take a while) they are not able to install GRASS addons via g.extension any more? This can't be true, there must be a mechanism to support installation of GRASS addons at least with the latest minor version of GRASS (7.8.x)?!?

Well, to some, there's the option of downloading the zip file and installing that. Not sure though if this works for all addons and all OSs. But, basically yes.

We have now GRASS 7.8.6 RC2 available for testing but I'm not sure if RCs reach distro's package managers. We cannot create binaries for windows because osgeo4w changed from version 1 to 2. @ninsbl is tirelessly working on setting that up (#1683). For mac users, @cmbarton already uploaded the packages here: http://grassmac.wikidot.com/downloads

I just recompiled GRASS GIS

→ g.version -r
GRASS 7.8.5dev (2020)
libgis revision: 744fcaefa
libgis date: 2020-10-16T16:00:53+00:00

Shouldn't this be enough to get a working g.extension as stated in https://grass.osgeo.org/news/2021_08_01_g_extension_currently_not_working/? However,

→ g.extension r.regression.series
Fetching <r.regression.series> from GRASS GIS Addons repository (be
patient)...
svn: E170000: URL 'https://github.com/OSGeo/grass-addons/trunk/grass7/raster/r.regression.series' doesn't exist
ERROR: GRASS Addons <r.regression.series> not found

• @ninsbl I know you work on this, no intention to press more

The fix is already merged and backported to release branch 78 as mentioned here https://github.com/OSGeo/grass/issues/1798#issuecomment-899461754

Would you please try grass 7.8.6 RC 2 and report back? AFAIU you are using 7.8.5 and it does not work there

[NikosAlexandris]

7.8.6 RC 2

It won't compile without errors here. I need to go through my configurations... A simple configuration/compilation might not work here for me as I am on my workstation setup that needs custom configurations.

[veroandreo]

The fix to g.extension was applied, backported and g.extension works in releasebranch, can we close this one?

there must be a mechanism to support installation of GRASS addons at least with the latest minor version of GRASS (7.8.x)?!?

Totally agreed, but it can be tricky to support custom/distro installations because of DLL dependencies... I do have my own compiled binaries and cannot install addons :-(.

With 7.8.6 release the issue is solved. Feel free to re-open if needed.
