Hi Tim, While your at GRASS provider in Processing: I noticed that it (still) uses linked OGR data (v.external). However, that does not work for all algorithms and particularly not for all data types. Points are less of a problem, but areas are often. See: https://lists.osgeo.org/pipermail/grass-dev/2017-November/086601.html and https://lists.osgeo.org/pipermail/grass-dev/2017-November/086505.html
v.external.out (https://grass.osgeo.org/grass72/manuals/v.external.out.html) might be used though instead of v.our.ogr. But there might be drawbacks too. For raster data and algorithms r.external.out would speed-up the algorithms significantly… Cheers Stefan From: QGIS-Developer [mailto:[email protected]] On Behalf Of Tim Sutton Sent: onsdag 29. november 2017 18.49 To: Larry Shaffer <[email protected]> Cc: QGIS Developer <[email protected]> Subject: Re: [QGIS-Developer] Python error in processing on 2.99 startup Hi Thanks for your quick reply Larry.

Processing loads and GRASS algs open. (Not sure if True is needed for other platforms; untested.) Fix not pushed. Please verify on your setup first (mine is macOS 10.11.6). Thanks!
