#2814: digitizer crashes, leaves vector broken
-------------------------------+-------------------------
Reporter: harrikoo | Owner: grass-dev@…
Type: defect | Status: new
Priority: normal | Milestone: 7.0.3
Component: wxGUI | Version: 7.0.2
Keywords: digitizer, vector | CPU: Unspecified
Platform: Unspecified |
-------------------------------+-------------------------
I have yet to build a case where this manifests consistently, but it has
appeared several times. I describe some features of the defect:
1. Usually happens when crossing lines and boundaries: moving vertices
around so that existing lines cross, thus creating new lines/areas. But
not always; I haven't found a regular pattern yet.
2. digitizer crashes immeadiately, as does wxgui
3. topology is not built. After v.build, the coordinate file is larger
than it should be, and v.build reports that the vector contains lots of
incorrect boundaries. v.build is unable to fix these, and using v.clean
does not seem to help either.
4. the vector cannot be opened in the digitizer, as the digitizer crashes
immediately upon opening the corrupted vector.
5. the data in the vector can be salvaged with a judicious used of 'v.edit
tool=delete' or by using 'v.extract' with right criteria to move the
correct features to a new vector.
I can send a coor file of a vector demonstrating the results of this bug
to someone interested in seeing it.
