pip install failing for pypy3.11

Reproduce the failure with the provided Docker command and compare it with installing from commit e265ae0. Inspect how the 0.6.4 release bundles the generated C files and verify the release uses Cython 3.1. Done means pip install httptools==0.6.4 succeeds under the specified PyPy 3.11 image.

pip install httptools==0.6.4 fails under pypy3.11 with the log output below.

The issue is the Cython generated C files bundled with the release in pypi, similar to this one for lxml. In fact installing directly from the 0.6.4 commit works fine: pip install git+https://github.com/MagicStack/httptools@e265ae0.

The suggested fix there is to build a release with the 3.1 release of Cython which has this fix: https://github.com/cython/cython/pull/6482

how to reproduce

if you have docker, this is probably the easiest way to reproduce:

docker run -it --entrypoint=/bin/bash pypy:3.11-7.3.19 -c 'pip install httptools==0.6.4'
