libgis and libvect memory leaks

Reported by: neteler Owned by: grass-dev@…
Priority: major Milestone: 6.4.2
Component: LibVector Version: svn-releasebranch64
Keywords: library Cc: neteler
CPU: x86-64 Platform: Linux

Description

It seems that v.distance has a memory leak when run in LatLong? locations (version from today):

GRASS 6.3.svn (latlong_sphere):~ > CMD="v.distance -p -a coordinate_all_flocks_map to=coordinate_all_flocks_map upload=dist col=distance"
GRASS 6.3.svn (latlong_sphere):~ > valgrind --tool=memcheck --leak-check=yes --show-reachable=yes  $CMD --o

comment:7 Changed 5 years ago by neteler

Component: DefaultLibVector
Resolution: wontfix
Status: newclosed
Version: svn-trunksvn-releasebranch64

Tested in G7 relbranch/r63512 and memory consumption is much lower than in G6.4.svn (as expected).

Test case G6:

export GRASS_OVERWRITE=1
v.random -z random n=50 zmin=0 zmax=1000
CMD="v.distance -p -a random to=random upload=dist column=dummy"
valgrind --tool=memcheck --leak-check=yes --show-reachable=yes $CMD

Test case G7:

export GRASS_OVERWRITE=1
v.random -z random n=50 zmin=0 zmax=1000
CMD="v.distance -p -a random to=random upload=dist"
valgrind --tool=memcheck --leak-check=yes --show-reachable=yes $CMD

Given the massive rewrite of the vector engine in G7, I'll close this as wontfix for G6.
