Hi,
found a bug in gis.m zoom out tool.
start gis.m, select zoom out, draw a box, and poof! gis.m crashes.
happens always in a lat long location when you zoom out past 90NS 180EW
view or a bit harder to trigger in spearfish, but crashes on the 4th or
5th zoom out when the rows*cols gets to be something silly like 500e6*500e6.
presumably g.region exits with an error which isn't handled well.
testing with a few revisions of mapcanvas.tcl:
(the oldest error handling gives the most useful debug info here)
mapcanvas.tcl rev <= 1.57:
popup window:
ERROR: <n=541> ** invalid input **
ERROR: <n=541> ** invalid input **
while executing
"close $input"
(procedure "MapCanvas::runprograms" line 40)
invoked from within
"MapCanvas::runprograms $mon [expr {$mymodified != 0}]"
(procedure "MapCanvas::drawmap" line 38)
[...]
mapcanvas.tcl rev 1.58, .59:
popup window:
child process exited abnormally
child process exited abnormally
while executing
"close $input"
(procedure "MapCanvas::runprograms" line 40)
invoked from within
"MapCanvas::runprograms $mon [expr {$mymodified != 0}]"
(procedure "MapCanvas::drawmap" line 38)
[...]
mapcanvas.tcl rev 1.60 and newer:
gis.m crashes completely with "child process exited abnormally" printed
at the terminal prompt.
6.2.1 spearfish + huge region gives this error:
ERROR: Invalid region: North must be larger than South
ERROR: Invalid region: North must be larger than South
while executing
"close $input"
(procedure "MapCanvas::runprograms" line 39)
invoked from within
"MapCanvas::runprograms $mon [expr {$mymodified != 0}]"
(procedure "MapCanvas::drawmap" line 38)
6.2.1 lat/lon + beyond 90NS gives this error:
ERROR: <n=491.58331367> ** invalid input **
ERROR: <n=491.58331367> ** invalid input **
while executing
"close $input"
(procedure "MapCanvas::runprograms" line 39)
invoked from within
"MapCanvas::runprograms $mon [expr {$mymodified != 0}]"
(procedure "MapCanvas::drawmap" line 38)
