I looked over this patch and have various questions/comments. In
rough priority order:
I'm concerned about the moderately heavy use of macros wrt to debugging.
I noticed the use of alloca(). This isn't used in the core anywhere
(except a few uses on Windows). That might be an issue. I didn't
check how it was used.
I noticed that calculating the height was recursive. Not sure where
this function was called from, but does it handle blists which contain
Have you tried running this code under regrtest.py with the -R flag to
check for memory leaks?
There were C++ (//) style comments and C99 declarations of variables.
These would have to be changed if included in the core. Also, size_t
and Py_ssize_t should be used throughout. (ssize_t should be
Py_ssize_t). I noticed a bunch of ints and unsigneds. Although I
also noticed you used PyIndex_Check().
In general I thought the code was pretty good. Had a decent amount of
error checking/handling. There were some cases I wasn't sure, but in
the paths that I traced, I didn't find any obvious problems.
