If summary or since is empty, we used to return NULL in COMMAND DOCS. Currently all redis commands will have these two fields. But not for module command, summary and since are optional for RM_SetCommandInfo. With the change in #10043, if a module command doesn't have the summary or since, redis-cli will crash (see #10250). In this commit, COMMAND DOCS avoid adding summary or since when they are missing.

Fix redis-cli with sentinel crash due to SENTINEL DEBUG missing summary Because SENTINEL DEBUG missing summary in its json file, with the change in #10043, the following assertion will fail. ``` [redis]# src/redis-cli -p 26379 redis-cli: redis-cli.c:678: cliInitCommandHelpEntry: Assertion `reply->type == 1' failed. ``` This commit add the summary and complexity for SENTINEL DEBUG, which introduced in #9291, and also improved the help message.

Changes: 1. Adds the `redis.acl_check_cmd()` api to lua scripts. It can be used to check if the current user has permissions to execute a given command. The new function receives the command to check as an argument exactly like `redis.call()` receives the command to execute as an argument. 2. In the PR I unified the code used to convert lua arguments to redis argv arguments from both the new `redis.acl_check_cmd()` API and the `redis.[p]call()` API. This cleans up potential duplicate code. 3. While doing the refactoring in 2 I noticed there's an optimization to reduce allocation calls when parsing lua arguments into an `argv` array in the `redis.[p]call()` implementation. These optimizations were introduced years ago in 48c49c48 and 4f686555. It is unclear why this was added. The original commit message claims a 4% performance increase which I couldn't recreate and might not be worth it even if it did recreate. This PR removes that optimization. Following are details of the benchmark I did that couldn't reveal any performance improvements due to this optimization: ``` benchmark 1: src/redis-benchmark -P 500 -n 10000000 eval 'return redis.call("ping")' 0 benchmark 2: src/redis-benchmark -P 500 -r 1000 -n 1000000 eval 'return redis.call("mset","k1__rand_int__","v1__rand_int__","k2__rand_int__","v2__rand_int__","k3__rand_int__","v3__rand_int__","k4__rand_int__","v4__rand_int__")' 0 benchmark 3: src/redis-benchmark -P 500 -r 1000 -n 100000 eval "for i=1,100,1 do redis.call('set','kk'..i,'vv'..__rand_int__) end return redis.call('get','kk5')" 0 benchmark 4: src/redis-benchmark -P 500 -r 1000 -n 1000000 eval 'return redis.call("mset","k1__rand_int__","v1__rand_int__","k2__rand_int__","v2__rand_int__","k3__rand_int__","v3__rand_int__","k4__rand_int__","v4__rand_int__xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx")' ``` I ran the benchmark on this branch with and without commit 68b71680a4d3bb8f0509e06578a9f15d05b92a47 Results in requests per second: cmd | without optimization | without optimization 2nd run | with original optimization | with original optimization 2nd run -- | -- | -- | -- | -- 1 | 461233.34 | 477395.31 | 471098.16 | 469946.91 2 | 34774.14 | 35469.8 | 35149.38 | 34464.93 3 | 6390.59 | 6281.41 | 6146.28 | 6464.12 4 | 28005.71 | | 27965.77 | As you can see, different use cases showed identical or negligible performance differences. So finally I decided to chuck the original optimization and simplify the code.

In #9788, now we stores all persistent append-only files in a dedicated directory. The name of the directory is determined by the appenddirname configuration parameter in redis.conf. Now each node have a separate folder. Update create-cluster clean to clean this default directory.

So far we only tested attributes using readraw, not the resp parser caches them, so that after getting the reply, you can query them if you want.

`PSYNC replicationid str_offset` will crash the server. The reason is in `masterTryPartialResynchronization`, we will call `getLongLongFromObjectOrReply` check the offset. With a wrong offset, it will add a reply and then trigger a full SYNC and the client become a replica. So crash in `c->bufpos == 0 && listLength(c->reply) == 0`. In this commit, we check the psync_offset before entering function `masterTryPartialResynchronization`, and return. Regardless of that crash, accepting the sync, but also replying with an error would have corrupt the replication stream.

This is a followup to #9656 and implements the following step mentioned in that PR: * When possible, extract all the help and completion tips from COMMAND DOCS (Redis 7.0 and up) * If COMMAND DOCS fails, use the static help.h compiled into redis-cli. * Supplement additional command names from COMMAND (pre-Redis 7.0) The last step is needed to add module command and other non-standard commands. This PR does not change the interactive hinting mechanism, which still uses only the param strings to provide somewhat unreliable and inconsistent command hints (see #8084). That task is left for a future PR. Co-authored-by:

Adds RM_SetCommandInfo, allowing modules to provide the following command info: * summary * complexity * since * history * hints * arity * key specs * args This information affects the output of `COMMAND`, `COMMAND INFO` and `COMMAND DOCS`, Cluster, ACL and is used to filter commands with the wrong number of arguments before the call reaches the module code. The recently added API functions for key specs (never released) are removed. A minimalist example would look like so: ```c RedisModuleCommand *mycmd = RedisModule_GetCommand(ctx,"mymodule.mycommand"); RedisModuleCommandInfo mycmd_info = { .version = REDISMODULE_COMMAND_INFO_VERSION, .arity = -5, .summary = "some description", }; if (RedisModule_SetCommandInfo(mycmd, &mycmd_info) == REDISMODULE_ERR) return REDISMODULE_ERR; ```` Notes: * All the provided information (including strings) is copied, not keeping references to the API input data. * The version field is actually a static struct that contains the sizes of the the structs used in arrays, so we can extend these in the future and old version will still be able to take the part they can support.

Change the sentinel config file to a directory in SENTINEL SET test. So it will now fail on the `rename` in `rewriteConfigOverwriteFile`. The test used to set the sentinel config file permissions to `000` to simulate failure. But it fails on centos7 / freebsd / alpine. (introduced in #10151) Other changes: 1. More error messages after the config rewrite failure. 2. Modify arg name `force_all` in `rewriteConfig` to `force_write`. (was rename in #9304) 3. Fix a typo in debug quicklist-packed-threshold, then -> than. (#9357)

When performing `SENTINEL SET`, Sentinel updates the local configuration file. Before this commit, failure to update the file would still result with an `+OK` reply. Now, a `-ERR Failed to save config file` error will be returned. Co-authored-by:

The script which generates the markdown docs from module.c is updated to include the version in which each module API function was introduced. The script uses git tags to find this information. If git is not available or if we're not in a git repo, the 'since' is silently skipped. The line `**Available since:** (version)` is added after the function prototype Rename to utils/generate-module-api-doc.rb

This is done to avoid a crash when the timer fires after the module was unloaded. Or memory leaks in case we wanted to just ignore the timer. It'll cause the MODULE UNLOAD command to return with an error Co-authored-by:

It seems that fix didn't really solve the problem with ASAN, and also introduced issues with other CI runs. unrelated: - make runtest-cluster able to take multiple --single arguments

As Sentinel relies upon consensus algorithm, all sentinel instances, randomize a time to initiate their next attempt to become the leader of the group. But time after time, all raffled the same value. The problem is in the line `srand(time(NULL)^getpid())` such that all spinned up containers get same time (in seconds) and same pid which is always 1. Added material `tv_usec` and verify that even consecutive calls brings different values and makes the difference.

For backwards compatibility in 6.x, channels default permission was set to `allchannels` however with 7.0, we should modify it and the default value should be `resetchannels` for better security posture. Also, with selectors in ACL, a client doesn't have to set channel rules everytime and by default the value will be `resetchannels`. Before this change ``` 127.0.0.1:6379> acl list 1) "user default on nopass ~* &* +@all" 127.0.0.1:6379> acl setuser hp on nopass +@all ~* OK 127.0.0.1:6379> acl list 1) "user default on nopass ~* &* +@all" 2) "user hp on nopass ~* &* +@all" 127.0.0.1:6379> acl setuser hp1 on nopass -@all (%R~sales*) OK 127.0.0.1:6379> acl list 1) "user default on nopass ~* &* +@all" 2) "user hp on nopass ~* &* +@all" 3) "user hp1 on nopass &* -@all (%R~sales* &* -@all)" ``` After this change ``` 127.0.0.1:6379> acl list 1) "user default on nopass ~* &* +@all" 127.0.0.1:6379> acl setuser hp on nopass +@all ~* OK 127.0.0.1:6379> acl list 1) "user default on nopass ~* &* +@all" 2) "user hp on nopass ~* resetchannels +@all" 127.0.0.1:6379> acl setuser hp1 on nopass -@all (%R~sales*) OK 127.0.0.1:6379> acl list 1) "user default on nopass ~* &* +@all" 2) "user hp on nopass ~* resetchannels +@all" 3) "user hp1 on nopass resetchannels -@all (%R~sales* resetchannels -@all)" ```

Add optional `notes` to keyspecs. Other changes: 1. Remove the "incomplete" flag from SORT and SORT_RO: it is misleading since "incomplete" means "this spec may not return all the keys it describes" but SORT and SORT_RO's specs (except the input key) do not return any keys at all. So basically: If a spec's begin_search is "unknown" you should not use it at all, you must use COMMAND KEYS; if a spec itself is "incomplete", you can use it to get a partial list of keys, but if you want all of them you must use COMMAND GETKEYS; otherwise, the spec will return all the keys 2. `getKeysUsingKeySpecs` handles incomplete specs internally

Try to fix the rebalance cluster test that's failing with ASAN daily: Looks like `redis-cli --cluster rebalance` gets `ERR Please use SETSLOT only with masters` in `clusterManagerMoveSlot()`. it happens when `12-replica-migration-2.tcl` is run with ASAN in GH Actions. in `Resharding all the master #0 slots away from it` So the fix (assuming i got it right) is to call `redis-cli --cluster check` before `--cluster rebalance`. p.s. it looks like a few other checks in these tests needed that wait, added them too. Other changes: * in instances.tcl, make sure to catch tcl test crashes and let the rest of the code proceed, so that if there was a redis crash, we'll find it and print it too. * redis-cli, try to make sure it prints an error instead of silently exiting. specifically about redis-cli: 1. clusterManagerMoveSlot used to print an error, only if the caller also asked for it (should be the other way around). 2. clusterManagerCommandReshard asked for an error, but didn't use it (probably tried to avoid the double print). 3. clusterManagerCommandRebalance didn't ask for the error, now it does. 4. making sure that other places in clusterManagerCommandRebalance print something before exiting with an error.

Sentinel tries to resolve instances hostname to IP only during registration. It might be that the instance is unavailable during that time, such as leader crashed and failover took place. Yet, promoted replica must support: - Register leader, even if it fails to resolve its hostname during failover - Try later to resolve it, if instance is disconnected. Note that this condition also support ip-change of an instance.

Change the name to unix-time-seconds or unix-time-milliseconds to be consistent. Change the type from INTEGER to UNIX_TIME. SET (EXAT and PXAT) was already ok. and naming aside, both PXAT and EXAT everywhere used unit-time (for both milliseconds and seconds). the only ones that where wrong are GETEX and XCLAIM (using "integer" for both seconds and milliseconds)
