Hi,
I opened issue #8215 about PyTuple_Parse*() outdated documentation. When I read the code, I found two functions: getbuffer() and convertbuffer(). getbuffer() checks that the buffer is contigious, whereas convertbuffer() doesn't. We can group formats by contigious check:
- contigious buffer: s, y*, z*, w*
- discontigious buffer: s#, y, z, t, w, w#
I tried to test formats accepting discontigious buffer but I didn't found any function or library to test this.
I'm not sure that functions using s#, y, z, t, w, w# format do really support discontigious buffer and it's just a bug in getargs.c.
Do someone have information about that? Should it be fixed (only accept contigious buffer)?
