Gitea not accepting "redis-cluster" as cache adapter/session provider

[SomanathThilak]

Description

Gitea is not accepting Cache ADAPTER or Session PROVIDER as "redis-cluster".

In the documentation it is mentioned to use string "redis-cluster" when redis cluster instance is used for cache/session. But when Gitea is installed with ADAPTER/PROVIDER set to redis-cluster, it is instead configuring it to memory.

On analysis of code, it seems string "redis-cluster" is not supported for ADAPTER/PROVIDER.

Cache :

gitea/modules/setting/cache.go

Line 53 in 58b204b

CacheService.Adapter = sec.Key("ADAPTER").In("memory", []string{"memory", "redis", "memcache", "twoqueue"})

Session:

gitea/modules/setting/session.go

Line 44 in 58b204b

SessionConfig.Provider = sec.Key("PROVIDER").In("memory",

gitea/modules/setting/session.go

Line 45 in 58b204b

[]string{"memory", "file", "redis", "mysql", "postgres", "couchbase", "memcache", "db"})

Documentation Reference
Cache - https://docs.gitea.com/1.20/administration/config-cheat-sheet#cache-cache
Session - https://docs.gitea.com/1.20/administration/config-cheat-sheet#session-session

When it is set to "redis" both cache/session seems to be working fine even for redis cluster instances.

The documentation was updated by #24717 . Maybe you can use redis directly even if it's a redis cluster?

Yes as mentioned in the issue , I had tried using redis instead of redis-cluster and it works fine. But since the documentation is different it should be updated.
