pycryptodome: add build-pycryptodome.yml for riscv64 wheels - #358
Merged
Conversation
pycryptodome ships no riscv64 wheels on PyPI. Mirror upstream's wheels.yml (cibuildwheel from a tag checkout, `python -m Crypto.SelfTest --skip-slow-tests`), narrowed to manylinux_riscv64. setup.py sets bdist_wheel's py_limited_api to cp37 unless the interpreter is free-threaded, so the matrix collapses to one cp37-abi3 wheel (built on cp312, re-tested on cp313/cp314) plus cp314t.

pycryptodome ships no riscv64 wheels on PyPI. This mirrors upstream's
wheels.yml
— cibuildwheel over a tag checkout, tested with
python -m Crypto.SelfTest --skip-slow-tests— narrowed tomanylinux_riscv64.setup.pypassespy_limited_api = cp37tobdist_wheelunless the interpreteris free-threaded, so the matrix collapses (gotcha 11) to two jobs:
build_abi3— onecp37-abi3wheel built on cp312 and re-tested on cp313/cp314via cibuildwheel's
find_compatible_wheel;build_freethreaded—cp314t(the image has no cp313t, so it is the onlyfree-threaded target even though upstream also publishes cp313t).
CIBW_TEST_REQUIRESadds upstream'srequirements-test.txtpin(
pycryptodome-test-vectors==1.0.22); without it SelfTest skips its Wycheproofvectors (2802 tests instead of 8035).
Local validation: both wheels build under QEMU riscv64 in
quay.io/pypa/manylinux_2_39_riscv64(cp37-abi3from cp312-cp312 andcp314-cp314t), and the wheel carriesLICENSE.rst+ 40.sofiles. Theextensions are
optional=Falseand every.sois loaded throughCrypto.Util._raw_apiwith no pure-Python fallback, so gotcha 20 does not apply— a missing
.sois a hard import error, not a silent degrade.
