Summary: v.buffer: switch to disable tolerance WARNING
Issue status: None
GRASS component: None
Operating system: None
Operating system version:Initial Comment:
Hi,I have just experienced, how expensive it can be, to write a WARNING
out for every point, when buffering. I try to build simple buffers
(only 8 points needed) around a lot of points - in one case 370.000 -
and for the reason I choose a high tolerance value (to be sure, it
will be reset to the max allowed one). THis works, but takes
unbelievably long with all the warnings:"WARNING: The tolerance was reset to ..."
Now I have commented out the warning in main.c of v.buffer, and
suddenly it is running like mad (30 seconds instead of over 10
minutes). So maybe it would be nice to :- either add another switch to turn off this warning
- or include it under the "--quiet" option (NO warning if "--quiet" set).
Another option is to prevent the warning from being issued more than
once.
