This is a followup work for #10278, and a discussion about #10279 The changes: - fix failed_calls in command stats for blocked clients that got error. including CLIENT UNBLOCK, and module replying an error from a thread. - fix latency stats for XREADGROUP that filed with -NOGROUP Theory behind which errors should be counted: - error stats represents errors returned to the user, so an error handled by a module should not be counted. - total error counter should be the same. - command stats represents execution of commands (even with RM_Call, and if they fail or get rejected it counts these calls in commandstats, so it should also count failed_calls) Some thoughts about Scripts: for scripts it could be different since they're part of user code, not the infra (not an extension to redis) we certainly want commandstats to contain all calls and errors a simple script is like mult-exec transaction so an error inside it should be counted in error stats a script that replies with an error to the user (using redis.error_reply) should also be counted in error stats but then the problem is that a plain `return redis.call("SET")` should not be counted twice (once for the SET and once for EVAL) so that's something left to be resolved in #10279

This includes two fixes: * We forgot to count non-key reallocs in defragmentation stats. * Fix the script defrag tests so to make dict entries less signigicant in fragmentation by making the scripts larger. This assures active defrage will complete and reach desired results. Some inherent fragmentation might exists in dict entries which we need to ignore. This lead to occasional CI failures.

Consider the following example: 1. geoadd k1 -0.15307903289794921875 85 n1 0.3515625 85.00019260486917005437 n2. 2. geodist k1 n1 n2 returns "4891.9380" 3. but GEORADIUSBYMEMBER k1 n1 4891.94 m only returns n1. n2 is in the boundingbox but out of search areas.So we let search areas contain boundingbox to get n2.

Modifications of this PR: 1. Support the verification of `Multi Part AOF`, while still maintaining support for the old-style `AOF/RDB-preamble`. `redis-check-aof` will automatically choose which mode to use according to the incoming file format. `Usage: redis-check-aof [--fix|--truncate-to-timestamp $timestamp] <AOF/manifest>` 2. Refactor part of the code to make it easier to understand 3. Currently only supports truncate (`--fix` or `--truncate-to-timestamp`) the last AOF file (may be `BASE` or `INCR`) The reasons for 3 above: - for `--fix`: Only the last AOF may be truncated, this is guaranteed by redis - for `--truncate-to-timestamp`: Normally, we only have `BASE` + `INCR` files at most, and `BASE` cannot be truncated(It only contains a timestamp annotation at the beginning of the file), so only `INCR` can be truncated. If we have a `BASE+INCR1+INCR2` file (meaning we have an interrupted AOFRW), Only `INCR2` files can be truncated at this time. If we still insist on truncate `INCR1`, we need to manually delete `INCR2` and update the manifest file, then re-run `redis-check-aof` - If we want to support truncate any file, we need to add very complicated code to support the atomic modification of multiple file deletion and update manifest, I think this is unnecessary

This PR handles several aspects 1. Calls to RM_ReplyWithError from thread safe contexts don't violate thread safety. 2. Errors returning from RM_Call to the module aren't counted in the statistics (they might be handled silently by the module) 3. When a module propagates a reply it got from RM_Call to it's client, then the error statistics are counted. This is done by: 1. When appending an error reply to the output buffer, we avoid updating the global error statistics, instead we cache that error in a deferred list in the client struct. 2. When creating a RedisModuleCallReply object, the deferred error list is moved from the client into that object. 3. when a module calls RM_ReplyWithCallReply we copy the deferred replies to the dest client (if that's a real client, then that's when the error statistics are updated to the server) Note about RM_ReplyWithCallReply: if the original reply had an array with errors, and the module replied with just a portion of the original reply, and not the entire reply, the errors are currently not propagated and the errors stats will not get propagated. Fix #10180

Added regression tests for #10020 / #10081 / #10243. The above PRs fixed some crashes due to an asserting, see function `clientHasPendingReplies` (introduced in #9166). This commit added some tests to cover the above scenario. These tests will all fail in #9166, althought fixed not, there is value in adding these tests to cover and verify the changes. And it also can cover #8868 (verify the logs). Other changes: 1. Reduces the wait time in `waitForBgsave` and `waitForBgrewriteaof` from 1s to 50ms, which should reduce the time for some tests. 2. Improve the test infra to print context when `assert_match` fails. 3. Improve the test infra to print `$error` when `assert_error` fails. ``` Expected an error matching 'ERR*' but got 'OK' (context: type eval line 4 cmd {assert_error "ERR*" {r set a b}} proc ::test) ```

Remove scripts defragger since it was broken since #10126 (released in 7.0 RC1). would crash the server if defragger starts in a server that contains eval scripts. In #10126 the global `lua_script` dict became a dict to a custom `luaScript` struct with an internal `robj` in it instead of a generic `sds` -> `robj` dict. This means we need custom code to defrag it and since scripts should never really cause much fragmentation it makes more sense to simply remove the defrag code for scripts.

The bug is introduced by #9323. (released in 7.0 RC1) The define of `REDISMODULE_OPTIONS_HANDLE_IO_ERRORS` and `REDISMODULE_OPTION_NO_IMPLICIT_SIGNAL_MODIFIED` have the same value. This will result in skipping `signalModifiedKey()` after `RM_CloseKey()` if the module has set `REDISMODULE_OPTIONS_HANDLE_REPL_ASYNC_LOAD` option. The implication is missing WATCH and client side tracking invalidations. Other changes: - add `no-implicit-signal-modified` to the options in INFO modules Co-authored-by:

This is an enhancement for INFO command, previously INFO only support one argument for different info section , if user want to get more categories information, either perform INFO all / default or calling INFO for multiple times. **Description of the feature** The goal of adding this feature is to let the user retrieve multiple categories via the INFO command, and still avoid emitting the same section twice. A use case for this is like Redis Sentinel, which periodically calling INFO command to refresh info from monitored Master/Slaves, only Server and Replication part categories are used for parsing information. If the INFO command can return just enough categories that client side needs, it can save a lot of time for client side parsing it as well as network bandwidth. **Implementation** To share code between redis, sentinel, and other users of INFO (DEBUG and modules), we have a new `genInfoSectionDict` function that returns a dict and some boolean flags (e.g. `all`) to the caller (built from user input). Sentinel is later purging unwanted sections from that, and then it is forwarded to the info `genRedisInfoString`. **Usage Examples** INFO Server Replication INFO CPU Memory INFO default commandstats Co-authored-by:

This PR handles inconsistencies in errors returned from lua scripts. Details of the problem can be found in #10165. ### Changes - Remove double stack trace. It's enough that a stack trace is automatically added by the engine's error handler see https://github.com/redis/redis/blob/d0bc4fff18afdf9e5421cc88e23ffbb876ecaec3/src/function_lua.c#L472-L485 and https://github.com/redis/redis/blob/d0bc4fff18afdf9e5421cc88e23ffbb876ecaec3/src/eval.c#L243-L255 - Make sure all errors a preceded with an error code. Passing a simple string to `luaPushError()` will prepend it with a generic `ERR` error code. - Make sure lua error table doesn't include a RESP `-` error status. Lua stores redis error's as a lua table with a single `err` field and a string. When the string is translated back to RESP we add a `-` to it. See https://github.com/redis/redis/blob/d0bc4fff18afdf9e5421cc88e23ffbb876ecaec3/src/script_lua.c#L510-L517 So there's no need to store it in the lua table. ### Before & After ```diff --- <unnamed> +++ <unnamed> @@ -1,14 +1,14 @@ 1: config set maxmemory 1 2: +OK 3: eval "return redis.call('set','x','y')" 0 - 4: -ERR Error running script (call to 71e6319f97b0fe8bdfa1c5df3ce4489946dda479): @user_script:1: @user_script: 1: -OOM command not allowed when used memory > 'maxmemory'. + 4: -ERR Error running script (call to 71e6319f97b0fe8bdfa1c5df3ce4489946dda479): @user_script:1: OOM command not allowed when used memory > 'maxmemory'. 5: eval "return redis.pcall('set','x','y')" 0 - 6: -@user_script: 1: -OOM command not allowed when used memory > 'maxmemory'. + 6: -OOM command not allowed when used memory > 'maxmemory'. 7: eval "return redis.call('select',99)" 0 8: -ERR Error running script (call to 4ad5abfc50bbccb484223905f9a16f09cd043ba8): @user_script:1: ERR DB index is out of range 9: eval "return redis.pcall('select',99)" 0 10: -ERR DB index is out of range 11: eval_ro "return redis.call('set','x','y')" 0 -12: -ERR Error running script (call to 71e6319f97b0fe8bdfa1c5df3ce4489946dda479): @user_script:1: @user_script: 1: Write commands are not allowed from read-only scripts. +12: -ERR Error running script (call to 71e6319f97b0fe8bdfa1c5df3ce4489946dda479): @user_script:1: ERR Write commands are not allowed from read-only scripts. 13: eval_ro "return redis.pcall('set','x','y')" 0 -14: -@user_script: 1: Write commands are not allowed from read-only scripts. +14: -ERR Write commands are not allowed from read-only scripts. ```

Fix #7021 #8924 #10198 # Intro Before this commit X[AUTO]CLAIM used to transfer deleted entries from one PEL to another, but reply with "nil" for every such entry (instead of the entry id). The idea (for XCLAIM) was that the caller could see this "nil", realize the entry no longer exists, and XACK it in order to remove it from PEL. The main problem with that approach is that it assumes there's a correlation between the index of the "id" arguments and the array indices, which there isn't (in case some of the input IDs to XCLAIM never existed/read): ``` 127.0.0.1:6379> XADD x 1 f1 v1 "1-0" 127.0.0.1:6379> XADD x 2 f1 v1 "2-0" 127.0.0.1:6379> XADD x 3 f1 v1 "3-0" 127.0.0.1:6379> XGROUP CREATE x grp 0 OK 127.0.0.1:6379> XREADGROUP GROUP grp Alice COUNT 2 STREAMS x > 1) 1) "x" 2) 1) 1) "1-0" 2) 1) "f1" 2) "v1" 2) 1) "2-0" 2) 1) "f1" 2) "v1" 127.0.0.1:6379> XDEL x 1 2 (integer) 2 127.0.0.1:6379> XCLAIM x grp Bob 0 0-99 1-0 1-99 2-0 1) (nil) 2) (nil) ``` # Changes Now, X[AUTO]CLAIM acts in the following way: 1. If one tries to claim a deleted entry, we delete it from the PEL we found it in (and the group PEL too). So de facto, such entry is not claimed, just cleared from PEL (since anyway it doesn't exist in the stream) 2. since we never claim deleted entries, X[AUTO]CLAIM will never return "nil" instead of an entry. 3. add a new element to XAUTOCLAIM's response (see below) # Knowing which entries were cleared from the PEL The caller may want to log any entries that were found in a PEL but deleted from the stream itself (it would suggest that there might be a bug in the application: trimming the stream while some entries were still no processed by the consumers) ## XCLAIM the set {XCLAIM input ids} - {XCLAIM returned ids} contains all the entry ids that were not claimed which means they were deleted (assuming the input contains only entries from some PEL). The user doesn't need to XACK them because XCLAIM had already deleted them from the source PEL. ## XAUTOCLAIM XAUTOCLAIM has a new element added to its reply: it's an array of all the deleted stream IDs it stumbled upon. This is somewhat of a breaking change since X[AUTO]CLAIM used to be able to reply with "nil" and now it can't... But since it was undocumented (and generally a bad idea to rely on it, as explained above) the breakage is not that bad.

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.

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.

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)

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)" ```

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.

SET is a R+W command, because it can also do `GET` on the data. SET without GET is a write-only command. SET with GET is a read+write command. In #9974, we added ACL to let users define write-only access. So when the user uses SET with GET option, and the user doesn't have the READ permission on the key, we need to reject it, but we rather not reject users with write-only permissions from using the SET command when they don't use GET. In this commit, we add a `getkeys_proc` function to control key flags in SET command. We also add a new key spec flag (VARIABLE_FLAGS) means that some keys might have different flags depending on arguments. We also handle BITFIELD command, add a `bitfieldGetKeys` function. BITFIELD GET is a READ ONLY command. BITFIELD SET or BITFIELD INCR are READ WRITE commands. Other changes: 1. SET GET was added in 6.2, add the missing since in set.json 2. Added tests to cover the changes in acl-v2.tcl 3. Fix some typos in server.h and cleanups in acl-v2.tcl Co-authored-by:

This PR attempts to solve two problems that happen sometime in valgrind: `ERR Background save already in progress` and `not bgsave not aborted` the test used to populate the database with DEBUG, which didn't increment the dirty counter, so couldn't trigger an automatic bgsave. then it used a manual bgsave, and aborted it (when it got aborted it populated the dirty counter), and then it tried to do another bgsave. that other bgsave could have failed if the automatic one already started.

Failed on a non-valgrind run. on this line: ``` assert_equal 0 [$slave exists k] ``` the condition in `keyIsExpired` is `now > when`. so if the test is really fast, maybe it can get to EXISTS exactly 1000 milliseconds after the expiration was set, and the key isn't yet gone)

This is an attempt to fix some of the issues with the cluster mode tests we are seeing in the daily run. The test is trying to incrementally adds a bunch of publish messages, expecting that eventually one of them will overflow. The tests stops one of the processes, so it expects that just that one Redis node will overflow. I think the test is flaky because under certain circumstances multiple links are getting disconnected, not just the one that is stalled.

This PR aims to improve the flags associated with some commands and adds various tests around these cases. Specifically, it's concerned with commands which declare keys but have no ACL flags (think `EXISTS`), the user needs either read or write permission to access this type of key. This change is primarily concerned around commands in three categories: # General keyspace commands These commands are agnostic to the underlying data outside of side channel attacks, so they are not marked as ACCESS. * TOUCH * EXISTS * TYPE * OBJECT 'all subcommands' Note that TOUCH is not a write command, it could be a side effect of either a read or a write command. # Length and cardinality commands These commands are marked as NOT marked as ACCESS since they don't return actual user strings, just metadata. * LLEN * STRLEN * SCARD * HSTRLEN # Container has member commands These commands return information about the existence or metadata about the key. These commands are NOT marked as ACCESS since the check of membership is used widely in write commands e.g. the response of HSET. * SISMEMBER * HEXISTS # Intersection cardinality commands These commands are marked as ACCESS since they process data to compute the result. * PFCOUNT * ZCOUNT * ZINTERCARD * SINTERCARD
