Feature request #3433
GEOSException not exposed through python bindings
|Pull Request or Patch supplied:||Resolution:||fixed|
|Easy fix?:||No||Copied to github as #:||13493|
If you try and parse some invalid WKT (or do a number of other bad things), GEOS will throw an error you can't catch from Python, causing the interpreter to crash.
>>> from qgis.core import [[QgsGeometry]] >>> # WKT has a missing ')' >>> [[QgsGeometry]].fromWkt("POLYGON((0 0, 1 0, 1 1, 0 0)") terminate called after throwing an instance of 'GEOSException' Aborted
ideally a developer should be able to catch it with:
>>> from qgis.core import [[QgsGeometry]], GEOSException >>> try: >>> [[QgsGeometry]].fromWkt("POLYGON((0 0, 1 0, 1 1, 0 0)") >>> except GEOSException, e: >>> print "uh oh, WKT error: %s" % e
