Now we will check the offset in zrangeGenericCommand. With a negative offset, we will throw an error and return. This also resolve the issue of zeroing the destination key in case of the "store" variant when we input a negative offset. ``` 127.0.0.1:6379> set key value OK 127.0.0.1:6379> zrangestore key myzset 0 10 byscore limit -1 10 (integer) 0 127.0.0.1:6379> exists key (integer) 0 ``` This change affects the following commands: - ZRANGE / ZRANGESTORE / ZRANGEBYLEX / ZRANGEBYSCORE - ZREVRANGE / ZREVRANGEBYSCORE / ZREVRANGEBYLEX

Try lazyfree temp zset in ZUNION / ZINTER / ZDIFF and optimize ZINTERCARD to avoid create temp zset (#12229) We check lazyfree_lazy_server_del in sunionDiffGenericCommand to see if we need to lazyfree the temp set. Now do the same in zunionInterDiffGenericCommand to lazyfree the temp zset. This is a minor change, follow #5903. Also improved the comments. Additionally, avoid creating unused zset object in ZINTERCARD, results in some 10% performance improvement.

Optimized HRANDFIELD and ZRANDMEMBER commands as in #8444, CASE 3 under listpack encoding. Boost optimization to CASE 2.5. CASE 2.5 listpack only. Sampling unique elements, in non-random order. Listpack encoded hashes / zsets are meant to be relatively small, so HRANDFIELD_SUB_STRATEGY_MUL / ZRANDMEMBER_SUB_STRATEGY_MUL isn't necessary and we rather not make copies of the entries. Instead, we emit them directly to the output buffer. Simple benchmarks shows it provides some 400% improvement in HRANDFIELD and ZRANGESTORE both in CASE 3. Unrelated changes: remove useless setTypeRandomElements and fix a typo.

Performance improvement to ZADD and ZRANGESTORE, convert to skiplist and expand dict in advance (#12185) For zsets that will eventually be stored as the skiplist encoding (has a dict), we can convert it to skiplist ahead of time. This change checks the number of arguments in the ZADD command, and converts the data-structure if the number of new entries exceeds the listpack-max-entries configuration. This can cause us to over-allocate memory if there are duplicate entries in the input, which is unexpected. For ZRANGESTORE, we know the size of the zset, so we can expand the dict in advance, to avoid the temporary dict from being rehashed while it grows. Simple benchmarks shows it provides some 4% improvement in ZADD and 20% in ZRANGESTORE

Related to the hang reported in #11671 Currently, redis can disconnect a client due to reaching output buffer limit, it'll also avoid feeding that output buffer with more data, but it will keep running the loop in the command (despite the client already being marked for disconnection) This PR is an attempt to mitigate the problem, specifically for commands that are easy to abuse, specifically: KEYS, HRANDFIELD, SRANDMEMBER, ZRANDMEMBER. The RAND family of commands can take a negative COUNT argument (which is not bound to the number of elements in the key), so it's enough to create a key with one field, and then these commands can be used to hang redis. For KEYS the caller can use the existing keyspace in redis (if big enough).

*TL;DR* --------------------------------------- Following the discussion over the issue [#7551](https://github.com/redis/redis/issues/7551) We decided to refactor the client blocking code to eliminate some of the code duplications and to rebuild the infrastructure better for future key blocking cases. *In this PR* --------------------------------------- 1. reprocess the command once a client becomes unblocked on key (instead of running custom code for the unblocked path that's different than the one that would have run if blocking wasn't needed) 2. eliminate some (now) irrelevant code for handling unblocking lists/zsets/streams etc... 3. modify some tests to intercept the error in cases of error on reprocess after unblock (see details in the notes section below) 4. replace '$' on the client argv with current stream id. Since once we reprocess the stream XREAD we need to read from the last msg and not wait for new msg...

In #11290, we added listpack encoding for SET object. But forgot to support it in zuiFind, causes ZINTER, ZINTERSTORE, ZINTERCARD, ZIDFF, ZDIFFSTORE to crash. And forgot to support it in RM_ScanKey, causes it hang. This PR add support SET listpack in zuiFind, and in RM_ScanKey. And add tests for related commands to cover this case. Other changes: - There is no reason for zuiFind to go into the internals of the SET. It can simply use setTypeIsMember and don't care about encoding. - Remove the `#include "intset.h"` from server.h reduce the chance of accidental intset API use. - Move setTypeAddAux, setTypeRemoveAux and setTypeIsMemberAux interfaces to the header. - In scanGenericCommand, use setTypeInitIterator and setTypeNext to handle OBJ_SET scan. - In RM_ScanKey, improve hash scan mode, use lpGetValue like zset, they can share code and better performance. The zuiFind part fixes #11578 Co-authored-by:

Small sets with not only integer elements are listpack encoded, by default up to 128 elements, max 64 bytes per element, new config `set-max-listpack-entries` and `set-max-listpack-value`. This saves memory for small sets compared to using a hashtable. Sets with only integers, even very small sets, are still intset encoded (up to 1G limit, etc.). Larger sets are hashtable encoded. This PR increments the RDB version, and has an effect on OBJECT ENCODING Possible conversions when elements are added: intset -> listpack listpack -> hashtable intset -> hashtable Note: No conversion happens when elements are deleted. If all elements are deleted and then added again, the set is deleted and recreated, thus implicitly converted to a smaller encoding.

The use case is a module that wants to implement a blocking command on a key that necessarily exists and wants to unblock the client in case the key is deleted (much like what we implemented for XREADGROUP in #10306) New module API: * RedisModule_BlockClientOnKeysWithFlags Flags: * REDISMODULE_BLOCK_UNBLOCK_NONE * REDISMODULE_BLOCK_UNBLOCK_DELETED ### Detailed description of code changes blocked.c: 1. Both module and stream functions are called whether the key exists or not, regardless of its type. We do that in order to allow modules/stream to unblock the client in case the key is no longer present or has changed type (the behavior for streams didn't change, just code that moved into serveClientsBlockedOnStreamKey) 2. Make sure afterCommand is called in serveClientsBlockedOnKeyByModule, in order to propagate actions from moduleTryServeClientBlockedOnKey. 3. handleClientsBlockedOnKeys: call propagatePendingCommands directly after lookupKeyReadWithFlags to prevent a possible lazy-expire DEL from being mixed with any command propagated by the preceding functions. 4. blockForKeys: Caller can specifiy that it wants to be awakened if key is deleted. Minor optimizations (use dictAddRaw). 5. signalKeyAsReady became signalKeyAsReadyLogic which can take a boolean in case the key is deleted. It will only signal if there's at least one client that awaits key deletion (to save calls to handleClientsBlockedOnKeys). Minor optimizations (use dictAddRaw) db.c: 1. scanDatabaseForDeletedStreams is now scanDatabaseForDeletedKeys and will signalKeyAsReady for any key that was removed from the database or changed type. It is the responsibility of the code in blocked.c to ignore or act on deleted/type-changed keys. 2. Use the new signalDeletedKeyAsReady where needed blockedonkey.c + tcl: 1. Added test of new capabilities (FSL.BPOPGT now requires the key to exist in order to work)

when we know the size of the zset we're gonna store in advance, we can check if it's greater than the listpack encoding threshold, in which case we can create a skiplist from the get go, and avoid converting the listpack to skiplist later after it was already populated.

When `zrangestore` is called container destination object is created. Before this PR we used to create a listpack based object even if `zset-max-ziplist-entries` or equivalent`zset-max-listpack-entries` was set to 0. This triggered immediate conversion of the listpack into a skiplist in `zrangestore`, which hits an assertion resulting in an engine crash. Added a TCL test that reproduces this issue.

This bug was introduced in #9484 (7.0.0). It result that BZMPOP blocked on non-key arguments. Like `bzmpop 0 1 myzset min count 10`, this command will additionally block in these keys (except for the first and the last argument) and can return their values: - 0: timeout value - 1: numkeys value - min: min/max token - count: count token

When the score doesn't have fractional part, and can be stored as an integer, we use the integer capabilities of listpack to store it, rather than convert it to string. This already existed before this PR (lpInsert dose that conversion implicitly). But to do that, we would have first converted the score from double to string (calling `d2string`), then pass the string to `lpAppend` which identified it as being an integer and convert it back to an int. Now, instead of converting it to a string, we store it using lpAppendInteger`. Unrelated: --- * Fix the double2ll range check (negative and positive ranges, and also the comparison operands were slightly off. but also, the range could be made much larger, see comment). * Unify the double to string conversion code in rdb.c with the one in util.c * Small optimization in lpStringToInt64, don't attempt to convert strings that are obviously too long. Benchmark; --- Up to 20% improvement in certain tight loops doing zzlInsert with large integers. (if listpack is pre-allocated to avoid realloc, and insertion is sorted from largest to smaller)

There are a few places that use a hard coded const of 128 to allocate a buffer for d2string. Replace these with a clear macro. Note that In theory, converting double into string could take as much as nearly 400 chars, but since d2string uses `%g` and not `%f`, it won't pass some 40 chars. unrelated: restore some changes to auto generated commands.c that got accidentally reverted in #10293

1. since ZSKIPLIST_P is float, using it directly inside the condition used to causes floating point code to be used (gcc/x86) 2. In some operating system(eg.Windows), the largest value returned from random() is 0x7FFF(15bit), so after bitwise AND with 0xFFFF, the probability of the less operation returning true in the while loop's condition is no more equal to ZSKIPLIST_P. 3. In case some library has random() returning int in range [0~ZSKIPLIST_P*65535], the while loop will be an infinite loop. 4. on Linux where RAND_MAX is higher than 0xFFFF, this change actually improves precision (despite not matching the result against a float value)

Writable replicas now no longer use the values of expired keys. Expired keys are deleted when lookupKeyWrite() is used, even on a writable replica. Previously, writable replicas could use the value of an expired key in write commands such as INCR, SUNIONSTORE, etc.. This commit also sorts out the mess around the functions lookupKeyRead() and lookupKeyWrite() so they now indicate what we intend to do with the key and are not affected by the command calling them. Multi-key commands like SUNIONSTORE, ZUNIONSTORE, COPY and SORT with the store option now use lookupKeyRead() for the keys they're reading from (which will not allow reading from logically expired keys). This commit also fixes a bug where PFCOUNT could return a value of an expired key. Test modules commands have their readonly and write flags updated to correctly reflect their lookups for reading or writing. Modules are not required to correctly reflect this in their command flags, but this change is made for consistency since the tests serve as usage examples. Fixes #6842. Fixes #7475.

Part three of implementing #8702, following #8887 and #9366 . ## Description of the feature 1. Replace the ziplist container of quicklist with listpack. 2. Convert existing quicklist ziplists on RDB loading time. an O(n) operation. ## Interface changes 1. New `list-max-listpack-size` config is an alias for `list-max-ziplist-size`. 2. Replace `debug ziplist` command with `debug listpack`. ## Internal changes 1. Add `lpMerge` to merge two listpacks . (same as `ziplistMerge`) 2. Add `lpRepr` to print info of listpack which is used in debugCommand and `quicklistRepr`. (same as `ziplistRepr`) 3. Replace `QUICKLIST_NODE_CONTAINER_ZIPLIST` with `QUICKLIST_NODE_CONTAINER_PACKED`(following #9357 ). It represent that a quicklistNode is a packed node, as opposed to a plain node. 4. Remove `createZiplistObject` method, which is never used. 5. Calculate listpack entry size using overhead overestimation in `quicklistAllowInsert`. We prefer an overestimation, which would at worse lead to a few bytes below the lowest limit of 4k. ## Improvements 1. Calling `lpShrinkToFit` after converting Ziplist to listpack, which was missed at #9366. 2. Optimize `quicklistAppendPlainNode` to avoid memcpy data. ## Bugfix 1. Fix crash in `quicklistRepr` when ziplist is compressed, introduced from #9366. ## Test 1. Add unittest for `lpMerge`. 2. Modify the old quicklist ziplist corrupt dump test. Co-authored-by:

This is similar to the recent addition of LMPOP/BLMPOP (#9373), but zset. Syntax for the new ZMPOP command: `ZMPOP numkeys [<key> ...] MIN|MAX [COUNT count]` Syntax for the new BZMPOP command: `BZMPOP timeout numkeys [<key> ...] MIN|MAX [COUNT count]` Some background: - ZPOPMIN/ZPOPMAX take only one key, and can return multiple elements. - BZPOPMIN/BZPOPMAX take multiple keys, but return only one element from just one key. - ZMPOP/BZMPOP can take multiple keys, and can return multiple elements from just one key. Note that ZMPOP/BZMPOP can take multiple keys, it eventually operates on just on key. And it will propagate as ZPOPMIN or ZPOPMAX with the COUNT option. As new commands, if we can not pop any elements, the response like: - ZMPOP: Return a NIL in both RESP2 and RESP3, unlike ZPOPMIN/ZPOPMAX return emptyarray. - BZMPOP: Return a NIL in both RESP2 and RESP3 when timeout is reached, like BZPOPMIN/BZPOPMAX. For the normal response is nested arrays in RESP2 and RESP3: ``` ZMPOP/BZMPOP 1) keyname 2) 1) 1) member1 2) score1 2) 1) member2 2) score2 In RESP2: 1) "myzset" 2) 1) 1) "three" 2) "3" 2) 1) "two" 2) "2" In RESP3: 1) "myzset" 2) 1) 1) "three" 2) (double) 3 2) 1) "two" 2) (double) 2 ```

Implements the [LIMIT limit] variant of SINTERCARD/ZINTERCARD. Now with the LIMIT, we can stop the searching when cardinality reaching the limit, and return the cardinality ASAP. Note that in SINTERCARD, the old synatx was: `SINTERCARD key [key ...]` In order to add a optional parameter, we must break the old synatx. So the new syntax of SINTERCARD will be consistent with ZINTERCARD. New syntax: `SINTERCARD numkeys key [key ...] [LIMIT limit]`. Note that this means that SINTERCARD has a different syntax than SINTER and SINTERSTORE (taking numkeys argument) As for ZINTERCARD, we can easily add a optional parameter to it. New syntax: `ZINTERCARD numkeys key [key ...] [LIMIT limit]`

Part two of implementing #8702 (zset), after #8887. ## Description of the feature Replaced all uses of ziplist with listpack in t_zset, and optimized some of the code to optimize performance. ## Rdb format changes New `RDB_TYPE_ZSET_LISTPACK` rdb type. ## Rdb loading improvements: 1) Pre-expansion of dict for validation of duplicate data for listpack and ziplist. 2) Simplifying the release of empty key objects when RDB loading. 3) Unify ziplist and listpack data verify methods for zset and hash, and move code to rdb.c. ## Interface changes 1) New `zset-max-listpack-entries` config is an alias for `zset-max-ziplist-entries` (same with `zset-max-listpack-value`). 2) OBJECT ENCODING will return listpack instead of ziplist. ## Listpack improvements: 1) Add `lpDeleteRange` and `lpDeleteRangeWithEntry` functions to delete a range of entries from listpack. 2) Improve the performance of `lpCompare`, converting from string to integer is faster than converting from integer to string. 3) Replace `snprintf` with `ll2string` to improve performance in converting numbers to strings in `lpGet()`. ## Zset improvements: 1) Improve the performance of `zzlFind` method, use `lpFind` instead of `lpCompare` in a loop. 2) Use `lpDeleteRangeWithEntry` instead of `lpDelete` twice to delete a element of zset. ## Tests 1) Add some unittests for `lpDeleteRange` and `lpDeleteRangeWithEntry` function. 2) Add zset RDB loading test. 3) Add benchmark test for `lpCompare` and `ziplsitCompare`. 4) Add empty listpack zset corrupt dump test.

We want to add COUNT option for BLPOP. But we can't do it without breaking compatibility due to the command arguments syntax. So this commit introduce two new commands. Syntax for the new LMPOP command: `LMPOP numkeys [<key> ...] LEFT|RIGHT [COUNT count]` Syntax for the new BLMPOP command: `BLMPOP timeout numkeys [<key> ...] LEFT|RIGHT [COUNT count]` Some background: - LPOP takes one key, and can return multiple elements. - BLPOP takes multiple keys, but returns one element from just one key. - LMPOP can take multiple keys and return multiple elements from just one key. Note that LMPOP/BLMPOP can take multiple keys, it eventually operates on just one key. And it will propagate as LPOP or RPOP with the COUNT option. As a new command, it still return NIL if we can't pop any elements. For the normal response is nested arrays in RESP2 and RESP3, like: ``` LMPOP/BLMPOP 1) keyname 2) 1) element1 2) element2 ``` I.e. unlike BLPOP that returns a key name and one element so it uses a flat array, and LPOP that returns multiple elements with no key name, and again uses a flat array, this one has to return a nested array, and it does for for both RESP2 and RESP3 (like SCAN does) Some discuss can see: #766 #8824

Reduce dict struct memory overhead on 64bit dict size goes down from jemalloc's 96 byte bin to its 56 byte bin. summary of changes: - Remove `privdata` from callbacks and dict creation. (this affects many files, see "Interface change" below). - Meld `dictht` struct into the `dict` struct to eliminate struct padding. (this affects just dict.c and defrag.c) - Eliminate the `sizemask` field, can be calculated from size when needed. - Convert the `size` field into `size_exp` (exponent), utilizes one byte instead of 8. Interface change: pass dict pointer to dict type call back functions. This is instead of passing the removed privdata field. In the future if we'd like to have private data in the callbacks we can extract it from the dict type. We can extend dictType to include a custom dict struct allocator and use it to allocate more data at the end of the dict struct. This data can then be used to store private data later acccessed by the callbacks.
