unable to remove raster map after using it as a mask

[martinl]

Steps to reproduce this bug:

g.region rast=ofoto.alpha
r.mask raster=ofoto.alpha mask=0 -i
r.mask -r

Even the mask has been removed, it's not possible to remove raster map ofoto.alpha:

g.remove rast name=ofoto.alpha -f
WARNING: Raster map <ofoto.alpha@OstrovaciceHrbitov> is a base map. Remove reclassed map <MASK@OstrovaciceHrbitov> first.

I can confirm this. As mentioned in an email a few days ago, even if the MASK is removed already, in the GRASSdb/location/mapset/cell_misc/rastername there is the file 'reclassed_to' which contains the pointer to the MASK. Removing this file solves the problem.

Changes which potentially cause this:

• g.rename: r60976 | backport: r64011
• manage/lister: r62085 | backport: r64013

r.mask -i first creates a reclassified MASK map and renames it to a temporary map. Then, it creates a non-reclass MASK map based on the temporary map. This issue occurs when g.rename renames MASK to a temp name because g.rename is not updating reference info in the reclassed_to file for the base raster map at all.

The above commits should fix this issue. Please test it again.

I can confirm, it seems to be fixed. Thanks for super-quick fix. It's hot candidate for backport.
