remove some dead code for libzmq2 support, add some Cython type annotations #2082

minrk · 2025-03-16T11:35:11Z

move device from backend wrapping libzmq zmq_device removed in libzmq3 to sugar wrapping backend.proxy (unchanged behavior, just removed duplicate definitions in backends)
use more stable ABI-friendly buffer calls in new _asbuffer
new pure-python Cython mode could use some more type annotations to reduce unnecessary Python C-API calls
remove _check_version calls for unsupported versions

it's a deprecated wrapper for zmq.proxy, no need to have two implementations

readme has some redundant content from docs, not in sync

clearer type annotations, avoid some unnecessary Python calls

less work when it's time to try stable ABI wheels

otherwise, LAST_ENDPOINT is annoying

avoids OverflowError hooray tests!

can't define module global C types
