ftools: error in select by location

[bjpfei]

1.) open select by location

2.) choose two db-layers (seems that it doesn't matter if line or polygon

3.) ok

ftools version 0.5.9 You get a python error
"/home/bjsvwpfe/.qgis/python/plugins/fTools/tools/doSelectByLocation.py", line 61, in compute

geomLayer = QgsGeometry(feat.geometry())

TypeError: argument 1 of QgsGeometry() has an invalid type

thx

I cannot replicate the python error (using ftools 0.5.10) under ubuntu 9.04/win xp and qgis 1.2 but I can produce and replicate qgis freeze using the same "select by location" tool.

Take the qgis sample dataset and pick a polygon layer (ex. grassland) and a line layer (ex. trails and majrivers): if I select features in grassland intersecting features in trails is all ok, if repeat the same but with majrivers instead of trails, than wgis freezes.

The error occurs when you use PostGIS Layer for the analysis. The following error is reported:

Traceback (most recent call last):
  File "/usr/local/qgis-trunk/share/qgis/python/plugins/fTools/tools/doSelectByLocation.py", line 52, in accept

Ok, confirmed also this error when using postgis layers:

An error has occured while executing Python code:

All this issues are confirmed in the latest trunk qgis code.

Should be fixed in r13205

I seem to be getting a similar error when running on two very large polygon vector shapefiles (select features in a layer with 820,154 small footprint records, that intersect features in a layer with 7,766 large footprint records). using fTools 0.5.10, qGIS 1.6.0:

Replying to bderstine:

The above error is not related to the previously posted error, this 'new error' is a Windows IO problem that we have encountered before. This being the case, this issue has also already been resolved in trunk. Please ensure that you are in fact using the latest version of QGIS, and also the latest version of fTools (which is in fact the one installed by default). Looking at the source for the "select by location" tool, the offending print statement is no longer there in recent versions.

Carson, thanks for the response. I was using the Standalone Installer of release 1.6.0, but have now switched to the OSGeo4W Installer using the qgis-dev package in order to get the nightly builds of trunk. It works great.
