#2023: r.li.edgedensity
------------------------------+---------------------------------------------
Reporter: matmar | Owner: grass-dev@…
Type: defect | Status: new
Priority: normal | Milestone: 6.4.3
Component: Raster | Version: unspecified
Keywords: r.li.edgedensity | Platform: Linux
Cpu: x86-64 |
------------------------------+---------------------------------------------
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:

----

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.

Comment(by matmar):

(sorry for the cc mishap)

I have retried with a smaller region, still failing:

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):

Comment(by mmetz):

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.
