Subject: Re: [Plplot-devel] segfault bugfix for plbuf.c
I test the code by using the xwin driver and resize the plot window.
But I think a better way would be to write a test program that makes a plot and
then calls plRemakePlot. I will put something together
Hi Jim
In general plexit calls are bad. In fact it is on my to do list to go
through and eradicate them.
However, I'm not sure what alternative there is as the rendering
cannot continue, because once an unknown command is found there is no
way to know how many bytes to skipto find the next
I agree the plexit call is bad, I put it in primarily for debugging and I've
been thinking of alternatives.
I'm going to implement your idea. I'm going to add a data type suffix to each
command. Arrays will also have a size passed (which is what plbuf currently
does). The data type prefix

As Jim said resizing xwin or the current wxWidgets driver uses the

To Phil and Jim:
Do any of our current examples or device drivers on master branch
exercise the plbuf capabilities or if not could one of you implement a
test application that exercises each of the plbuf capabilities?
I think we need such a test that can be run to make sure that a plbuf

I guess it would help if I would attach the patch!

While working on the plot metafile, I fixed a segfault issue that Phil was
having with his wxWidgets work. I made a patch that fixes this issue. I don't
know about the need to push this to patch to master. The only jarring behavior
is a plexit() call that I put in plbuf_control() to catch

Phil's wxWidgets work is also a good test case.
