Hi folks!
I have just ran into buffer protocol incompatibility problem with
numpy-1.5.1, which lead me to discover the following ticket (discussed
back in December 2010 on this list):
http://trac.cython.org/cython_trac/ticket/630
In despair, I was about to try to see if there is anything I can do to
fix it myself. To this end I cloned your git repository and set up my
Python environment to use the latest bleeding edge version from there.
To my surprise I discovered that my code started working and I don't
have the buffer interface problem that I was facing before anymore.
So my suggestion would be to maybe test it more thoroughly and if it is
indeed the case, close the ticket. I tried to subscribe to it or leave a
comment, but I need an account which I can't register on my own.
I'm opposed to close the ticket. Cython cannot currently parse format
strings according to the full spec. It worked for you just because of
some quick fixes I've pushed for simple cases.
Pauli Virtanen fixed this and there's a pull request here:
https://github.com/cython/cython/pull/17
I'll get to it in a couple of days if nobody beats me to it.
BTW, did anyone figure out how to get emailed on pull requests? (Yes, I
checked off all the "send me email" boxes etc., we were talking about
this during the workshop -- it seems that org admins can't subscribe...)
And BTW, the Cython test suite exposed a bug in NumPy as well -- you can
see it in the test case comments. So there may be NumPy builds (and
releases?) out there that fail the Cython test suite because of a bug in
NumPy.
It only affect unpacked structs though; I believe you're good with
packed structs (and few use NumPy with unpacked structs).
