r.li.edgedensity

Description (last modified by )
r.li.edgedensity doesn't work using a configuration file (generated with r.li.setup) with a vector map to overlay. Attached you can find the generated configuration file.
The r.li.edgedensity error is:
GRASS 6.4.3svn (WGS_84):~ > r.li.edgedensity map=globcover conf=landscape output=edge_den_map --o ERROR: Program error, worker() toReceive.type=-1451052184 Segmentation fault (core dumped) ERROR: Program error, worker() toReceive.type=-1451052184 ERROR: Program error, worker() toReceive.type=-1451052184 ERROR: Program error, worker() toReceive.type=-1451052184 ERROR: Program error, worker() toReceive.type=-1451052184 ERROR: Program error, worker() toReceive.type=-1451052184 ERROR: Program error, worker() toReceive.type=-1451052184 ERROR: Program error, worker() toReceive.type=-1451052184 ERROR: Program error, worker() toReceive.type=-1451052184 ERROR: Program error, worker() toReceive.type=-1451052184
Thanks, Matteo

Hi Markus, this is the output of g.region -p when the command fails:
GRASS 6.4.3svn (WGS_84):~ > g.region -p projection: 3 (Latitude-Longitude) zone: 0 datum: wgs84 ellipsoid: wgs84 north: 57:13:46.281738N south: 0 west: 6:28:24.499626W east: 85:05:08.853149E nsres: 0:00:09.99982 ewres: 0:00:09.999798 rows: 20603 cols: 32962 cells: 679116086

To me it looks like a kind of integer overflow:
Matteo, does it happen with a smaller region?
toReceive.type is from the r.li.daemon, and is declared as "int" in the msg struct in ipc.h. But it should only be a #defined constant 1-5, so I would rather guess that the stack is being smashed.
note in devbr6 (6.5svn) it respects the WORKERS=1 environment variable for easier debugging. there should be control for that in trunk too, but the multi-processor part has been rewritten there so controlling the number of jobs is probably a bit different.

ps- 'g.region -a res=0:00:10' might be nice to clean up the region settings
pps- if you take ownership of a bug (ie declare responsibility for fixing it) please manually add the mailing list in the cc field so the discussion gets echoed there.

(sorry for the cc mishap)
I have retried with a smaller region, still failing:
GRASS 6.4.3svn (WGS_84):~ > g.region -a res=0:10 -p projection: 3 (Latitude-Longitude) zone: 0 datum: wgs84 ellipsoid: wgs84 north: 90N south: 65S west: 180W east: 180E nsres: 0:10 ewres: 0:10 rows: 930 cols: 2160 cells: 2008800 GRASS 6.4.3svn (WGS_84):~ > r.li.edgedensity map=globcover conf=conf output=edge_den_map --o ERROR: Segmentation fault (core dumped) Program error, worker() toReceive.type=-729328792 ERROR: Program error, worker() toReceive.type=-729328792 ERROR: Program error, worker() toReceive.type=-729328792 ERROR: Program error, worker() toReceive.type=-729328792 ERROR: Program error, worker() toReceive.type=-729328792 ERROR: Program error, worker() toReceive.type=-729328792 ERROR: Program error, worker() toReceive.type=-729328792 ERROR: Program error, worker() toReceive.type=-729328792 ERROR: Program error, worker() toReceive.type=-729328792 ERROR: Program error, worker() toReceive.type=-729328792 GRASS 6.4.3svn (WGS_84):~ > cat /home/matteo/.r.li/history/conf SAMPLINGFRAME 0|0|1|1
I wonder if the failure is related to ticket #2024 (incomplete r.li configuration file, the "MASKEDOVERLAYAREA" entries are missing)?
Restoring the conf file as it should be, it still fails (here two subsequent runs):

r.li.edgedensity is fixed in trunk r59072. As with the other r.li modules, it works only reliably if the current region is set to the input raster.

Can you please post the output of "g.region -p" to see the settings of the computational region when the command fails?
