python - Where can I find a list of numpy functions which release the GIL?

Question

I have found several SO questions asking about this in one way or another, but none of them actually either give a list or refer to one.

This question refers to a wiki page, but while the wiki page talks about the GIL and multi-threading, it doesn't give a list of GIL releasing functions.

This mailing list post indicates that the only way to find out is to read the numpy source. Really?

It's not guaranteed to catch everything, but I just ran:

git grep nogil

in my clone of the numpy repository. It turns up 82 usages in 2 files:

• random/mtrand/mtrand.pyx
• random/mtrand/numpy.pxd
