Friendship Quest remix of mobius, a hotline server in go #cli https://git.r.bdr.sh/mobius/atom/hotline/presence.go?h=main 2026-06-25T14:44:23Z 2026-06-25T14:44:23Z Jeff Halter 868228+jhalter@users.noreply.github.com 2026-06-25T14:44:23Z urn:sha1:bba70d0a2903ab1fff5a2e89cff97cb1f6c7f82a Replace the leaky *redis.Client field on Server with a PresenceTracker interface that receives connect/rename/disconnect lifecycle events. This removes Redis-specific set encoding from hotline/server.go and the session handlers, and drops the redis dependency from the hotline package. The Redis implementation moves to mobius.RedisPresenceTracker, which owns the legacy "login::ip"/"login:nickname:ip" set encoding so existing deployments keep working. The API server reads online users through a new OnlineLister interface and falls back to the in-memory ClientMgr when no presence tracker is configured. Startup clearing of stale online state now happens unconditionally when Redis is configured, not only when the API server is enabled.
