This PR replaces old .../topics/... links with current links, specifically for the modules-api-ref.md file and the new automation that Paolo Lazzari is working on. A few of the topics links have redirects, but some don't. Best to use updated links.

`lpCompare()` in `quicklistCompare()` will call `lpGet()` again, which would be a waste. The change will result in a boost for all commands that use `quicklistCompre()`, including `linsert`, `lpos` and `lrem`.

This PR adds a new section to the `INFO` command output, called `keysizes`. This section provides detailed statistics on the distribution of key sizes for each data type (strings, lists, sets, hashes and zsets) within the dataset. The distribution is tracked using a base-2 logarithmic histogram. # Motivation Currently, Redis lacks a built-in feature to track key sizes and item sizes per data type at a granular level. Understanding the distribution of key sizes is critical for monitoring memory usage and optimizing performance, particularly in large datasets. This enhancement will allow users to inspect the size distribution of keys directly from the `INFO` command, assisting with performance analysis and capacity planning. # Changes New Section in `INFO` Command: A new section called `keysizes` has been added to the `INFO` command output. This section reports a per-database, per-type histogram of key sizes. It provides insights into how many keys fall into specific size ranges (represented in powers of 2). **Example output:** ``` 127.0.0.1:6379> INFO keysizes # Keysizes db0_distrib_strings_sizes:1=19,2=655,512=100899,1K=31,2K=29,4K=23,8K=16,16K=3,32K=2 db0_distrib_lists_items:1=5784492,32=3558,64=1047,128=676,256=533,512=218,4K=1,8K=42 db0_distrib_sets_items:1=735564=50612,8=21462,64=1365,128=974,2K=292,4K=154,8K=89, db0_distrib_hashes_items:2=1,4=544,32=141169,64=207329,128=4349,256=136226,1K=1 ``` ## Future Use Cases: The key size distribution is collected per slot as well, laying the groundwork for future enhancements related to Redis Cluster.

The crash happens whenever the user isn't accessible, for example, it isn't set for the context (when it is temporary) or in some other cases like `notifyKeyspaceEvent`. To properly check for the ACL compliance, we need to get the user name and the user to invoke other APIs. However, it is not possible if it crashes, and it is impossible to work that around in the code since we don't know (and **shouldn't know**!) when it is available and when it is not.

After running test in local, there will be a file named `.rediscli_history_test`, and it is not in `.gitignore` file, so this is considered to have changed the code base. It is a little annoying, this commit just clean up the temporary file. We should delete `.rediscli_history_test` in the end since the second server tests also write somethings into it, to make it corresponding, i put `set ::env(REDISCLI_HISTFILE) ".rediscli_history_test"` at the beginning. Maybe we also can add this file into `.gitignore`

1. `dbRandomKey`: excessive call to `dbFindExpires` (will always return 1 if `allvolatile` + anyway called inside `expireIfNeeded` 2. Add `deleteKeyAndPropagate` that is used by both expiry/eviction 3. Change the order of calls in `expireIfNeeded` to save redundant calls to `keyIsExpired` 4. `expireIfNeeded`: move `OBJ_STATIC_REFCOUNT` to `deleteKeyAndPropagate` 5. `performEvictions` now uses `deleteEvictedKeyAndPropagate` 6. active-expire: moved `postExecutionUnitOperations` inside `activeExpireCycleTryExpire` 7. `activeExpireCycleTryExpire`: less indentation + expire a key if `now == t` 8. rename `lazy_expire_disabled` to `allow_access_expired`

This PR introduces a new `SFLUSH` command to cluster mode that allows partial flushing of nodes based on specified slot ranges. Current implementation is designed to flush all slots of a shard, but future extensions could allow for more granular flushing. **Command Usage:** `SFLUSH <start-slot> <end-slot> [<start-slot> <end-slot>]* [SYNC|ASYNC]` This command removes all data from the specified slots, either synchronously or asynchronously depending on the optional SYNC/ASYNC argument. **Functionality:** Current imp of `SFLUSH` command verifies that the provided slot ranges are valid and cover all of the node's slots before proceeding. If slots are partially or incorrectly specified, the command will fail and return an error, ensuring that all slots of a node must be fully covered for the flush to proceed. The function supports both synchronous (default) and asynchronous flushing. In addition, if possible, SFLUSH SYNC will be run as blocking ASYNC as an optimization.

This PR is based on https://github.com/valkey-io/valkey/pull/996 Currently, for operations like SUNION or SDIFF, temporary set object can be intset or listpack. Search operation is costly for these encodings. This patch tries to set the temporary set object as hash table by default. It also tries to determine correct encoding for the temporary set object to reduce the unnecessary conversation. This change is supposed to give performance boost for tests like: - [memtier_benchmark-2keys-set-10-100-elements-sdiff](https://github.com/redis/redis-benchmarks-specification/blob/main/redis_benchmarks_specification/test-suites/memtier_benchmark-2keys-set-10-100-elements-sdiff.yml) 66.2% IMPROVEMENT - [memtier_benchmark-2keys-set-10-100-elements-sunion](https://github.com/redis/redis-benchmarks-specification/blob/main/redis_benchmarks_specification/test-suites/memtier_benchmark-2keys-set-10-100-elements-sunion.yml ) 126.5% IMPROVEMENT ------- Co-authored-by:

Replace usage of _addReplyLongLongWithPrefix with specific bulk/mbulk functions to reduce condition checks in hotpath. (#13520) Instead of adding runtime logic to decide which prefix/shared object to use when doing the reply we can simply use an inline method to avoid runtime overhead of condition checks, and also keep the code change small. Preliminary data show improvements on commands that heavily rely on bulk/mbulk replies (example of LRANGE). --------- Co-authored-by:

Optimize SSCAN command in case of listpack or intset encoding: avoid the usage of intermediate list. From 2N to N iterations (#13530) On SSCAN, in case of listpack and intset encoding we actually reply the entire set, and always reply with the cursor 0. For those cases, we don't need to accumulate the replies in a list and can completely avoid the overhead of list appending and then iterating over the list again -- meaning we do N iterations instead of 2N iterations over the SET and save intermediate memory as well. Preliminary benchmarks, `SSCAN set:100 0`, showcased an improvement of 60% as visible bellow on a SET with 100 string elements (listpack encoded).

If the hash previously had HFEs (hash-fields with expiration) but later no longer does, the key ref in the hash might become outdated after a MOVE, COPY, RENAME or RESTORE operation. These commands maintain the key ref only if HFEs are present. That is, we can only be sure that key ref is valid as long as the hash has HFEs.

PR #13428 doesn't fully resolve an issue where corruption errors can still occur on loading of cluster.nodes file - seen on upgrade where there were no shard_ids (from old Redis), 7.2.5 loading generated new random ones, and persisted them to the file before gossip/handshake could propagate the correct ones (or some other nodes unreachable). This results in a primary/replica having differing shard_id in the cluster.nodes and then the server cannot startup - reports corruption. This PR builds on #13428 by simply ignoring the replica's shard_id in cluster.nodes (if it exists), and uses the replica's primary's shard_id. Additional handling was necessary to cover the case where the replica appears before the primary in cluster.nodes, where it will first use a generated shard_id for the primary, and then correct after it loads the primary cluster.nodes entry. --------- Co-authored-by:

Found by @oranagra Currently, when the size of dict becomes 1, we do not check whether `delta` is positive or negative. As a result, `non_empty_dicts` is still incremented when the size of dict changes from 2 to 1. We should only increment `non_empty_dicts` when `delta` is positive, as this indicates the first time an element is inserted into the dict. --------- Co-authored-by:

This is a very easy optimization, that avoids duplicate computation of the object length for LREM, LPOS, LINSERT na LINDEX. We can see that sdslen takes 7.7% of the total CPU cycles of the benchmarks. Function Stack | CPU Time: Total | CPU Time: Self | Module | Function (Full) | Source File | Start Address -- | -- | -- | -- | -- | -- | -- listTypeEqual | 15.50% | 2.346s | redis-server | listTypeEqual | t_list.c | 0x845dd sdslen | 7.70% | 2.300s | redis-server | sdslen | sds.h | 0x845e4 Preliminary data showcases 4% improvement in the achievable ops/sec of LPOS in string elements, and 2% in int elements.
