Hi everyone!

In Qgis 2.16.2-2 and 2.16.2-3 the " Join" tool does not work . When trying to join two shapefiles , an error occurs :
"global name 'vproviderA' is not defined. See log for more details" .

Log:
File "C:/PROGRA1/QGIS21.16/apps/qgis/./python/plugins\processing\algs\qgis\Union.py", line 78, in processAlgorithm
geomType, vproviderA.crs())
NameError: global name 'vproviderA' is not defined.

I get the same error when using the Union tool on QGIS Master with Ubuntu 16.04. The error occurs when accessing the tool via the menu (Vector > Geoprocessing Tools > Union) or via the Processing toolbox (QGIS Algorithms > Vector overlay tools > Union).

Same error and manjaro linux (based on arch).

vproviderA has to be replaced by vlayerA line 78 of /usr/share/qgis/python/plugins/processing/algs/qgis/Union.py in Linux.
The modification seems to have been done already on qgis-master on github: https://github.com/qgis/QGIS/blob/master/python/plugins/processing/algs/qgis/Union.py
You can also presumably just replace your Union.py file by this one.

The same error on Windows 7 64 bit with QGIS 2.16

Same error on Windows 7 64 bit with QGIS 2.16.3, both within QGIS and from a standalone script. Editing "C:\OSGeo4W64\apps\qgis\python\plugins\processing\algs\qgis\Union.py" as suggested in #4 above does the trick for the Union tool from within QGIS. It seems to fix the problem in the standalone script, but now produces new errors:

ERROR 1: Attempt to write non-polygon (MULTILINESTRING) geometry to POLYGON type
shapefile.
ERROR 1: Attempt to write non-polygon (POINT) geometry to POLYGON type shapefile
