This change attempts to alleviate a minor memory usage degradation for Redis 6.2 and onwards when using rather large objects (~2k) in streams. Introduced in #6281, we pre-allocate the head nodes of a stream to be 4kb, to limit the amount of unnecessary initial reallocations that are done. However, if we only ever allocate one object because 2 objects exceeds the max_stream_entry_size, we never actually shrink it to fit the single item. This can lead to a lot of excessive memory usage. For smaller item sizes this becomes less of an issue, as the overhead decreases as the items become smaller in size. This commit also changes the MEMORY USAGE of streams, since it was reporting the lpBytes instead of the allocated size. This introduced an observability issue when diagnosing the memory issue, since Redis reported the same amount of used bytes pre and post change, even though the new implementation allocated more memory.

As `sdsRemoveFreeSpace` have an impact on performance even if it is a no-op (see details at #11508). Only call the function when there is a possibility that the string contains free space. * For strings coming from the network, it's only if they're bigger than PROTO_MBULK_BIG_ARG * For strings coming from scripts, it's only if they're smaller than LUA_CMD_OBJCACHE_MAX_LEN * For strings coming from modules, it could be anything.

String pattern matching had exponential time complexity on pathological patterns (CVE-2022-36021) (#11858) Authenticated users can use string matching commands with a specially crafted pattern to trigger a denial-of-service attack on Redis, causing it to hang and consume 100% CPU time.

Avoid calling unwatchAllKeys when running touchAllWatchedKeysInDb (which was unnecessary) This can potentially lead to use-after-free and memory corruption when the next entry pointer held by the watched keys iterator is freed when unwatching all keys of a specific client. found with address sanitizer, added a test which will not always fail (depending on the random dict hashing seed) problem introduced in #9829 (Reids 7.0) Co-authored-by:

Currently there is no BUG. However during some internal code changes I found that it can happen (for example in case new code will not update the buf_peak) which can currently lead to memory overrun which is much harder to detect and root cause. Why did I please the assert here? The reason is to be able to have the buf_peak value without the risk of it being overriden by the peak_reset

CLIENT NO-TOUCH added in #11483, but forgot to add the since field in the JSON file. This PR adds the since field to it with a value of 7.2.0

When no-touch mode is enabled, the client will not touch LRU/LFU of the keys it accesses, except when executing command `TOUCH`. This allows inspecting or modifying the key-space without affecting their eviction. Changes: - A command `CLIENT NO-TOUCH ON|OFF` to switch on and off this mode. - A client flag `#define CLIENT_NOTOUCH (1ULL<<45)`, which can be shown with `CLIENT INFO`, by the letter "T" in the "flags" field. - Clear `NO-TOUCH` flag in `clearClientConnectionState`, which is used by `RESET` command and resetting temp clients used by modules. - Also clear `NO-EVICT` flag in `clearClientConnectionState`, this might have been an oversight, spotted by @madolson. - A test using `DEBUG OBJECT` command to verify that LRU stat is not touched when no-touch mode is on.

There is a built in limit to client side tracking keys, which when exceeded will invalidate keys. This occurs in two places, one in the server cron and other before executing a command. If it happens in the second scenario, the invalidations will be queued for later since current client is set. This queue is never drained if a command is not executed (through call) such as a multi-exec command getting queued. This results in a later server assert crashing.
