Backward protocol compatibility #199

Open Erick555 opened 1 month ago

Erick555 commented 1 month ago

Recently in 2.3.0 pcsc release there was minor protocol version bump. This was first protocol bump in 6 years.

This creates problem for using pcsc in containers (i.e. flatpak) where there's one client version but multiple server versions. Not updating client means all new servers are broken - updating means all old servers are. How to prevent such hopeless situation? Is it possible to introduce protocol negotiation instead of mismatch failure?

Alternatively is it possible to revert above commit until solution for protocol compat is found?

Yes, it is a known issue. See https://salsa.debian.org/rousseau/PCSC/-/issues/22

I do not use flatpack myself. So I have no motivation to implement something.

I would love to work on a solution.
