Grass 7.2.1 returns "Extension(...)not found" when installing addon

[bcbernardo]

In GRASS GIS 7.2.1 (from the QGIS 2.18 suite), running on Windows 7 32 bits SP1, installing any addon with g.extension returns:

Downloading precompiled GRASS Addons <extension.name>...
"ERROR: Extension <extension.name> not found"

Running the module with verbose flag on adds the following line to result:

"Downloading source code for <extension.name> from <http://wingrass.fsv.cvut.cz/grass72/x86/addons/grass-7.2.1/extension.name.zip> which is identified as 'remote_zip' type of source..."

I have been trying to perform these installations for a few days, with no results, in more than one computer at my workplace. Re-installing QGIS suite does not appear to make any difference. The company's policy on downloading and opening executable files will not allow me to install a GRASS GIS stand-alone. I do can download the zipfile manually from the wingrass http index, though, which makes me think it is not a matter of server availability (as reported ​elsewhere) or internet access restrictions.

it's not clear how do you run the command, from GRASS Plugin Shell? Anyway there is no 'extension.name' Addons, see (1)

Reopen if needed.

The windows repository seems to be hardcoded to ​http://wingrass.fsv.cvut.cz/grass74/x86_64/addons/grass-7.4.4/ (in grass 7.4 at least).

The files are actually located at ​http://wingrass.fsv.cvut.cz/grass74/x86_64/addons/grass-7.4.svn/

    C:\>g.extension url="http://wingrass.fsv.cvut.cz/grass74/x86_64/addons/grass-7.4.svn/" 
    --verbose extension=v.tin.to.rast
    Downloading precompiled GRASS Addons <v.tin.to.rast>...

    which is identified as 'remote_zip' type of source...
    ERROR: Extension <v.tin.to.rast> not found

As shown above, the url parameter does not appear to work (unless I am not using it correctly).

The issues appears to be in function install_extension_win(name) at line 1011 of ​https://github.com/OSGeo/grass/blob/master/scripts/g.extension/g.extension.py

base_url = "http://wingrass.fsv.cvut.cz/" \
               "grass%(major)s%(minor)s/%(platform)s/addons/" \
               "grass-%(major)s.%(minor)s.%(patch)s" % \
               {'platform': platform,
                'major': version[0], 'minor': version[1],
                'patch': version[2]}

Copy scripts/g.extension.py to another location. Change as below. Run from File > Launch Script. It now works.

base_url = "http://wingrass.fsv.cvut.cz/" \
               "grass%(major)s%(minor)s/%(platform)s/addons/" \
               "grass-%(major)s.%(minor)s.%(patch)s" % \
               {'platform': platform,
                'major': version[0], 'minor': version[1],
                #'patch': version[2]}
		'patch': 'svn'}

the subject of the trac ticket is about Grass 7.2.1v. in windows.

winGRASS versions:

• GRASS GIS 7.4.4 (old stable)
• GRASS GIS 7.6.1 (new stable)

which winGRASS version are you refering to while reopening the ticket?

precompiled addon python scripts may work between different winGRASS releases; though it's very unlikely that C addons are working due to different GRASS library version.

user input/point of view/ideas very appreciated for this discussion.

I have created two pull requests:

• master: ​https://github.com/OSGeo/grass/pull/68
• relbranch76: ​https://github.com/OSGeo/grass/pull/69

If that works, then also relbranch74 etc. need related updates.

Please test (the pull request contains hints on testing).

Is the server at ​http://wingrass.fsv.cvut.cz/ independent of the grass project? If so there seems to be a risk of this re-occurring, so maybe a more informative error message would be useful?

The simplest solution to my mind would be to agree a structure with the maintainer of that server, so that the g.extension.py script is not broken.

If that is not possible, could we ask the maintainer to provide a sitemap that could be easily checked?

Is this still an issue with more recent versions?
