More information

Issues arose in #462 and #463

cryptography now requires openssl 3, so we need to statically link it in Bullseye which has openssl 1.1.

[bennuttall]

Figuring out how to fix it, but for now, please download these files and install as required:

• Bullseye (Python 3.9): https://www.piwheels.org/cp39/cryptography-43.0.0-cp37-abi3-linux_armv7l.whl
• Bookworm (Python 3.11): https://www.piwheels.org/cp311/cryptography-43.0.0-cp37-abi3-linux_armv7l.whl

Somewhat updating my question in #469:

Wouldn't fixing the tags in the build process with auditwheel to something like cp37-abi3-manylinux_2_31_armv7l for bullseye, and cp37-abi3-manylinux_2_36_armv7l for bookworm differentiate the built wheels sufficiently?

Edit: With excluding libssl.so.<X> and libcrypto.so.<X> from grafting?

[xmatthias]

seems like wheels for 43.0.3 are available now ...

is this a fluke, or has this process been fixed? (i didn't test them yet).

[orosam]

I just performed a quick test.

The 43.0.3 armv7l build (having sha256=aa694873d3f46d2af4480573597b341f891acdeefe21f37b9112df7004e4cd3e) appears to be linked against openssl3, and indeed it works on a bookworm based OS.

This coincides with the dependency info in the Project JSON at https://www.piwheels.org/project/cryptography/json/, under key .["releases"]["43.0.3"]["files"]["cryptography-43.0.3-cp37-abi3-linux_armv7l.whl"]["apt_dependencies"].

Whether it's deliberate or accidental that the bookworm wheel is there, I cannot tell. Previously (around 43.0.1 or 43.0.2 if I recall correctly), it was the same situation, just reversed: the bookworm wheel was missing, and the bullseye one was available.

[xmatthias]

i'm not sure if this (building cryptography as part of piwheels) is still necessary (not sure what the policies are for packages that provide upstream wheels).

cryptography now (since 44.0.0) provides armv7 wheels via pypi - and a test showed that they work fine on 3.11 (so bookworm).

While the file (cryptography-44.0.1-cp39-abi3-manylinux_2_28_armv7l.manylinux_2_31_armv7l.whl) points to cp39 (in my understanding, the minimum python version) ... it's working fine on 3.11 in my testing.

Yes, those are abi3 wheels, so the Python version there is the minimum version.
