Potential issue regarding ABI identification for PyPI manylinux purposes #63

Open xen0n opened 3 months ago

If we were to support LoongArch manylinux wheels on PyPI, we must be able to prevent installation of wheels built on a different world than that of the running system.

Right now, due to:

the multiarch specifiers for both worlds are the same, so we must be able to distinguish by other means. This is likely glibc symbol versions for glibc-based systems, but I think musl-based systems will need something else.

Maybe just check EF_LOONGARCH_OBJABI_V1 for every EM_LOONGARCH ELF files containing a SEC_LOAD | SEC_CODE | SEC_HAS_CONTENTS section in the wheel.

Or, we can add this check into libc loader (gated with something like a Glibc tunable) and the packages requiring such a check will be able to simply enable it.
