Re: [Qgis-user] [QGIS-Developer] Mac QGIS 3 GRASS fix

[Mr. Stace D Maples]

This thread is "Mac QGIS 3 GRASS fix, but I don't see anything that fixes the 
problem. Has anyone managed to get GRASS working in QGIS3 for OSX? I'm running 
the latest installer QGIS-macOS-3.2.0-1.dmg and it's still not working. 

Also, we've put an inquiry in with Andreas Neumann about how to support 
(financially and otherwise) the creation of proper OSX installers that are 
stable enough to depend upon for research and deploy enterprise wide. We've not 
heard back and it's been about 3 weeks. Is there another venue for us to 
contact QGIS.org to try to get this properly funded so we can move on to work 
that matters, rather than installing and uninstalling non-working distributions?

I don't think a file check will help, since it finds a file from the 
returned files list.  I do think the walking the whole grasspath tree is 
excessive.

Re: [Qgis-user] [QGIS-Developer] Mac QGIS 3 GRASS fix

[William Kyngesburye]

Is it the same error for what the pull request fixes?

"/Applications/QGIS3.app/Contents/MacOS/grass/etc/colors/grass: Permission 
denied"

That should be fixed, but GRASS7 still has unresolved problems in the macOS 
package.  I haven't had time to look at it.

I believe it's this bug:

https://issues.qgis.org/issues/17555

The permission errors is caused because it's actually trying to
execute /Applications/QGIS3.app/Contents/MacOS/grass/etc/colors/grass
instead of the correct grass binary.

The bug is caused by this function:

https://github.com/qgis/QGIS/blob/master/python/plugins/processing/algs/grass7/Grass7Utils.py#L130

It's trying to automatically generate the grass executable path, but
it's incorrectly finding the colors/grass folder and deciding that
it's the grass executable. I think inserting a os.path.isfile check
somewhere around line 145 should fix this, but not having access to an
osx install I haven't been able to test this.

Hope that helps -- would be great to have this one sorted for 3.0.1 if
you can confirm a fix!

Re: [Qgis-user] [QGIS-Developer] Mac QGIS 3 GRASS fix

[William Kyngesburye]

Yes, that looks like the source of the problem.  The os.walk() finds the color 
file named "grass" before it has a chance to find the real "grass72" file at 
the top level of the grasspath.  Though this is odd since it looks like os.walk 
by default should return a folder's info before it walks subfolders.

I don't think a file check will help, since it finds a file from the returned 
files list.  I do think the walking the whole grasspath tree is excessive.

Re: [Qgis-user] [QGIS-Developer] Mac QGIS 3 GRASS fix

I believe it's this bug:

https://issues.qgis.org/issues/17555

The permission errors is caused because it's actually trying to
execute /Applications/QGIS3.app/Contents/MacOS/grass/etc/colors/grass
instead of the correct grass binary.

The bug is caused by this function:

https://github.com/qgis/QGIS/blob/master/python/plugins/processing/algs/grass7/Grass7Utils.py#L130

It's trying to automatically generate the grass executable path, but
it's incorrectly finding the colors/grass folder and deciding that
it's the grass executable. I think inserting a os.path.isfile check
somewhere around line 145 should fix this, but not having access to an
osx install I haven't been able to test this.

Hope that helps -- would be great to have this one sorted for 3.0.1 if
you can confirm a fix!
