[Plplot-devel] Solved the xw09.py segfault

[Alan W. I. <ir...@be...>]

The long-standing segfault problem with xw09 using python 2 disappears if I
define pl_cont (and pl_shade) as static to make them consistent with what is
done for the embedded examples in the python documentation.  In the past
with python 1.5 I didn't get segfaults, but I did have a number of instances
of peculiar behaviour with pl_cont (contours would either be plotted or not
with minor rearrangements of the wrapper code).  Thus, I am hoping this
static fix will address those problems as well.  The static fix seems to have
no effect on pl_shade, but there may have been trouble lurking for us there
without that fix.

In the next day or so I am going to be greatly extending the xw09 contour
example so this should provide a pretty good test of whether our python
contour problems are finally over or not.

Does anybody here mind if I get rid of plmodule2.c and simply incorporate
its lines of code into plmodule.c?  The previous arrangement of separate
compilation of plmodule.c and plmodule2.c wasn't working very well and was
confusing.  For now, I have returned to including plmodule2.c in plmodule.c,
but as a final step I would like to simply incorporate its lines of code
into plmodule.c rather than including it.
