github.com/hanzokv/go/v9 v9.22.0 renamed its Go package from "redis" to "kv"; the import path is unchanged. A lock library is typed against the client it wraps -- the adapter's NewPool takes the client's UniversalClient and compares against the client's Nil sentinel -- so the qualifier change is load bearing, not cosmetic. Client-driven: - go.mod: github.com/hanzokv/go/v9 v9.21.1 -> v9.22.0 - the adapter for our client speaks kv.UniversalClient / kv.Nil, imported unaliased as in hanzokv/go's own sources Our own vocabulary follows: - redis/ -> kv/, package redis -> package kv. This is redsync's own Pool/Conn/Script abstraction over a KV backend, not anyone's product. - redis/goredis/v9 -> kv/kvgo (package kvgo). That adapter wraps hanzokv/go, not go-redis; the old name said the wrong thing. Its example moves with it: examples/goredis/v9 -> examples/kvgo. - import alias redsyncredis -> redsynckv - RedisError -> KVError (and its tests) - comments and README speak kv Deliberately NOT renamed, because they name foreign things: - the redigo, rueidis, valkeygo and go-redis v6/v7/v8 adapters, which target genuinely different clients, keep their names and their own "redis." qualifiers (redigo's redis.Conn, go-redis's redis.Nil) - the server-side Lua in scripts.go: redis.call is the store's scripting API. Rewriting it would change the script source and therefore the SHA1 hashes pinned in scripts.go, which TestScripts_Hash verifies against a live server. - upstream links (redis.io distlock post, redigo attribution) Import paths move from .../v4/redis/... to .../v4/kv/...; the module major stays v4 by policy. Verified with a local redis-server: go build ./..., go vet ./..., go test -count=1 ./... and go test -race -count=1 ./... all pass, TestScripts_Hash included.
