* Document redis: Object optionSteven Harman2019-04-181-5/+7
| | | | | | | There are four ways to pass the redis option, but only three were documented. This is now consistent with implementation. [ci skip]
* Redis fetch without names returns {}David Verhasselt2019-04-121-0/+1
| | | | | | | When trying to call mget in Redis without any parameters, a Redis error is thrown. To avoid this, we circumvent Redis entirely when there are no key names given.
* Switch to supports_cache_versioning? check to a class methodschneems2018-09-201-4/+2
| | | | | - Moving the `supports_cache_versioning?` check to a class method. - Shorten the method doc. - Expand on the error message.
* [close #33907] Error when using "recyclable" cache keys with a store that ↵schneems2018-09-201-0/+7
| | | | | | | | | | | | | | does not support it If you are using the "in cache versioning" also known as "recyclable cache keys" the cache store must be aware of this scheme, otherwise you will generate cache entries that never invalidate. This PR adds a check to the initialization process to ensure that if recyclable cache keys are being used via ``` config.active_record.cache_versioning = true ``` Then the cache store needs to show that it supports this versioning scheme. Cache stores can let Rails know that they support this scheme by adding a method `supports_in_cache_versioning?` and returning true.
* Refactor #33254.Kasper Timm Hansen2018-07-011-16/+16
| | | | | | | | | | | | | Firstly, increment and decrement shouldn't care about the particulars of key expiry. They should only know that they have to pass that responsibility on to somewhere else. Secondly, it moves the key normalization back inside the instrumentation like it was originally. I think that matches the original design intention or at the very least it lets users catch haywire key truncation. Thirdly, it moves the changelog entry to the top of the file, where new entries go. I couldn't understand what the entry was saying so I tried to rewrite it.

* Redis cache store: avoid blocking the server in `#delete_matched`Gleb Mazovetskiy2018-04-181-6/+13
| | | | | | | | | | | | | | | | | | | | Fixes #32610. Closes #32614. Lua scripts in redis are *blocking*, meaning that no other client can execute any commands while the script is running. See https://redis.io/commands/eval#atomicity-of-scripts. This results in the following exceptions once the number of keys is sufficiently large: BUSY Redis is busy running a script. You can only call SCRIPT KILL or SHUTDOWN NOSAVE. This commit replaces the lua-based implementation with one that uses `SCAN` and `DEL` in batches. This doesn't block the server. The primary limitation of `SCAN`, i.e. potential duplicate keys, is of no consequence here, because `DEL` ignores keys that do not exist.
* Fix redis store clear keys outside the namespaceRei2018-04-151-1/+1

* Redis cache store: fix constructing with a Redis instanceAdam Richardson2018-03-121-1/+1
| | | | | | | | Since `Redis#call` duck types as a Proc, we'd call `#call` on it, thinking it's a Proc. Fixed by check for the Proc explicitly instead of duck typing on `#call`. References #32233

* Built-in Redis cache storeJeremy Daer2017-11-131-0/+404
* Supports vanilla Redis, hiredis, and Redis::Distributed. * Supports Memcached-like sharding across Redises with Redis::Distributed. * Fault tolerant. If the Redis server is unavailable, no exceptions are raised. Cache fetches are treated as misses and writes are dropped. * Local cache. Hot in-memory primary cache within block/middleware scope. * `read_/write_multi` support for Redis mget/mset. Use Redis::Distributed 4.0.1+ for distributed mget support. * `delete_matched` support for Redis KEYS globs.
