livekit cannot use github.com/hanzokv/go, for a structural reason rather than a
stylistic one: the client type flows through two upstream libraries we do not
fork. livekit/protocol/redis.GetRedisClient PRODUCES a
github.com/redis/go-redis/v9.UniversalClient and livekit/psrpc CONSUMES one, so
substituting the client in the middle fails to type-check at both seams:
cannot use redis2.GetRedisClient(&conf.Redis) (go-redis UniversalClient)
as kv.UniversalClient in return statement
cannot use rc (kv.UniversalClient)
as go-redis UniversalClient in argument to psrpc.NewRedisMessageBus
Forking psrpc made it worse rather than better: livekit/protocol/rpc demands
livekit/psrpc's OWN types, so pointing at hanzoai/psrpc broke pkg/agent, which
had compiled. Verified by building pkg/agent at the commit before the fork
(compiles) and after (2 type errors) with a working SDKROOT — an earlier check
of mine reported "compiles in both" and was simply wrong.
So this repo keeps upstream go-redis and upstream psrpc (v0.7.1). That is the
honest consequence of livekit/protocol being unforkable: you cannot substitute a
client library inside a module whose upstream dependencies both produce and
consume that library's types.
What stays, because it is correct and independent: the module path
(github.com/hanzoai/livekit, which this fork now actually declares) and the
luxfi/metric repair in the parent commit that made this repo build at all.
