#1362: wxpython GUI closes suddenly
----------------------------------------+-----------------------------------
Reporter: lluis | Owner: grass-dev@…
Type: defect | Status: new
Priority: normal | Milestone: 7.0.0
Component: wxGUI | Version: svn-trunk
Keywords: wxpython, X Windows error, | Platform: Linux
Cpu: x86-64 |
----------------------------------------+-----------------------------------
I start grass70 with the wxpython interface and when I open a menu or a
window (for example, when I try to load a vector layer in de map display)
the GUI closes suddenly and I can read this message in the terminal:
"GRASS 7.0.svn (girona_4326):~ > The program 'python' received an X Window
System error.
This probably reflects a bug in the program.
The error was 'BadLength (poly request too large or internal Xlib length
erro'.
(Details: serial 17612 error_code 16 request_code 153 minor_code 0)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error()
function.)

I can confirm this behaviour, and it seems to be linked specifically to
adding vectors to the display, although I cannot confirm this with
absolute certitude. The crash does not happen systematically, and
sometimes I don't get a crash, but a freeze. Using g.gisenv set=WX_DEBUG=5
I see that it seems to happen just after a v.db.connect call.
I for myself am on Debian Squeeze, with wx 2.8.10.
I haven't tried the --sync debugging hinted at in the error message.

AFAICT, there were numerous bugs. The most serious bug was that vector
maps can have no DB link, but this was not taken into account by
v.db.connect and the wxGUI. The wxGui had other bugs, mostly related to
incorrect handling of return codes and output / error messages of modules
called by the wxGUI. I hope I fixed some of these bugs for trunk in r46277
and previous. Martin, please test my changes and backport what passes your
testing (after some improvement if needed).
