The initialize memory of `querybuf` is `PROTO_IOBUF_LEN(1024*16) * 2` (due to sdsMakeRoomFor being greedy), under `jemalloc`, the allocated memory will be 40k. This will most likely result in the `querybuf` being resized when call `clientsCronResizeQueryBuffer` unless the client requests it fast enough. Note that this bug existed even before #7875, since the condition for resizing includes the sds headers (32k+6). ## Changes 1. Use non-greedy sdsMakeRoomFor when allocating the initial query buffer (of 16k). 1. Also use non-greedy allocation when working with BIG_ARG (we won't use that extra space anyway) 2. in case we did use a greedy allocation, read as much as we can into the buffer we got (including internal frag), to reduce system calls. 3. introduce a dedicated constant for the shrinking (same value as before) 3. Add test for querybuf. 4. improve a maxmemory test by ignoring the effect of replica query buffers (can accumulate many ACKs on slow env) 5. improve a maxmemory by disabling slowlog (it will cause slight memory growth on slow env).

SINTERSTORE would have deleted the dest key right away, even when later on it is bound to fail on an (WRONGTYPE) error. With this change it first picks up all the input keys, and only later delete the dest key if one is empty. Also add more tests for some commands. Mainly focus on - `wrong type error`: expand test case (base on sinter bug) in non-store variant add tests for store variant (although it exists in non-store variant, i think it would be better to have same tests) - the dstkey result when we meet `non-exist key (empty set)` in *store sdiff: - improve test case about wrong type error (the one we found in sinter, although it is safe in sdiff) - add test about using non-exist key (treat it like an empty set) sdiffstore: - according to sdiff test case, also add some tests about `wrong type error` and `non-exist key` - the different is that in sdiffstore, we will consider the `dstkey` result sunion/sunionstore add more tests (same as above) sinter/sinterstore also same as above ...

The root cause is that one test (`5 keys in, 5 keys out`) is leaking a volatile key that can expire while another later test(`All TTL in commands are propagated as absolute timestamp in replication stream`) is running. Such leaked expiration injects an unexpected `DEL` command into the replication command during the later test, causing it to fail. The fixes are two fold: 1. Plug the leak in the first test. 2. Add FLUSHALL to the later test, to avoid future interference from other tests.

This PR adds a spell checker CI action that will fail future PRs if they introduce typos and spelling mistakes. This spell checker is based on blacklist of common spelling mistakes, so it will not catch everything, but at least it is also unlikely to cause false positives. Besides that, the PR also fixes many spelling mistakes and types, not all are a result of the spell checker we use. Here's a summary of other changes: 1. Scanned the entire source code and fixes all sorts of typos and spelling mistakes (including missing or extra spaces). 2. Outdated function / variable / argument names in comments 3. Fix outdated keyspace masks error log when we check `config.notify-keyspace-events` in loadServerConfigFromString. 4. Trim the white space at the end of line in `module.c`. Check: https://github.com/redis/redis/pull/7751 5. Some outdated https link URLs. 6. Fix some outdated comment. Such as: - In README: about the rdb, we used to said create a `thread`, change to `process` - dbRandomKey function coment (about the dictGetRandomKey, change to dictGetFairRandomKey) - notifyKeyspaceEvent fucntion comment (add type arg) - Some others minor fix in comment (Most of them are incorrectly quoted by variable names) 7. Modified the error log so that users can easily distinguish between TCP and TLS in `changeBindAddr`

This commit revives the improves the ability to run the test suite against external servers, instead of launching and managing `redis-server` processes as part of the test fixture. This capability existed in the past, using the `--host` and `--port` options. However, it was quite limited and mostly useful when running a specific tests. Attempting to run larger chunks of the test suite experienced many issues: * Many tests depend on being able to start and control `redis-server` themselves, and there's no clear distinction between external server compatible and other tests. * Cluster mode is not supported (resulting with `CROSSSLOT` errors). This PR cleans up many things and makes it possible to run the entire test suite against an external server. It also provides more fine grained controls to handle cases where the external server supports a subset of the Redis commands, limited number of databases, cluster mode, etc. The tests directory now contains a `README.md` file that describes how this works. This commit also includes additional cleanups and fixes: * Tests can now be tagged. * Tag-based selection is now unified across `start_server`, `tags` and `test`. * More information is provided about skipped or ignored tests. * Repeated patterns in tests have been extracted to common procedures, both at a global level and on a per-test file basis. * Cleaned up some cases where test setup was based on a previous test executing (a major anti-pattern that repeats itself in many places). * Cleaned up some cases where test teardown was not part of a test (in the future we should have dedicated teardown code that executes even when tests fail). * Fixed some tests that were flaky running on external servers.

Till now GET and NX were mutually exclusive. This change make their combination mean a "Get or Set" command. If the key exists it returns the old value and avoids setting, and if it does't exist it returns nil and sets it to the new value (possibly with expiry time)

The decision to stop trimming due to LIMIT in XADD and XTRIM was after the limit was reached. i.e. the code was deleting **at least** that count of records (from the LIMIT argument's perspective, not the MAXLEN), instead of **up to** that count of records. see #9046

The test that was merged yesterday fails with valgrind and freebsd CI that are too slow, and 10 seconds apparently passed between the time the command was sent to redis and the time it was actually executed. ``` *** [err]: All TTL in commands are propagated as absolute timestamp in replication stream in tests/unit/expire.tcl Expected 'del a' to match 'set foo1 bar PXAT *' (context: type source line 778 file /home/runner/work/redis/redis/tests/test_helper.tcl cmd {assert_match [lindex $patterns $j] [read_from_replication_stream $s]} proc ::assert_replication_stream level 1) ```

Till now, on replica full-sync we used to transfer absolute time for TTL, however when a command arrived (EXPIRE or EXPIREAT), we used to propagate it as is to replicas (possibly with relative time), but always translate it to EXPIREAT (absolute time) to AOF. This commit changes that and will always use absolute time for propagation. see discussion in #8433 Furthermore, we Introduce new commands: `EXPIRETIME/PEXPIRETIME` that allow extracting the absolute TTL time from a key.

When test stop 'load handler' by killing the process that generating the load, some commands that already in the input buffer, still might be processed by the server. This may cause some instability in tests, that count on that no more commands processed after we stop the `load handler' In this commit, new proc 'wait_load_handlers_disconnected' added, to verify that no more cammands from any 'load handler' prossesed, by checking that the clients who genreate the load is disconnceted. Also, replacing check of dbsize with wait_for_ofs_sync before comparing debug digest, as it would fail in case the last key the workload wrote was an overridden key (not a new one). Affected tests Race fix: - failover command to specific replica works - Connect multiple replicas at the same time (issue #141), master diskless=$mdl, replica diskless=$sdl - AOF rewrite during write load: RDB preamble=$rdbpre Cleanup and speedup: - Test replication with blocking lists and sorted sets operations - Test replication with parallel clients writing in different DBs - Test replication partial resync: $descr (diskless: $mdl, $sdl, reconnect: $reconnect

When client breached the output buffer soft limit but then went idle, we didn't disconnect on soft limit timeout, now we do. Note this also resolves some sporadic test failures in due to Linux buffering data which caused tests to fail if during the test we went back under the soft COB limit. Co-authored-by:

Adding a new type mask for key space notification, REDISMODULE_NOTIFY_MODULE, to enable unique notifications from commands on REDISMODULE_KEYTYPE_MODULE type keys (which is currently unsupported). Modules can subscribe to a module key keyspace notification by RM_SubscribeToKeyspaceEvents, and clients by notify-keyspace-events of redis.conf or via the CONFIG SET, with the characters 'd' or 'A' (REDISMODULE_NOTIFY_MODULE type mask is part of the '**A**ll' notation for key space notifications). Refactor: move some pubsub test infra from pubsub.tcl to util.tcl to be re-used by other tests.

Before this commit using RM_Call without "!" could cause the master to lazy-expire a key (delete it) but without replicating to replicas. This could cause the replica's memory usage to gradually grow and could also cause consistency issues if the master and replica have a clock diff. This bug was introduced in #8617 Added a test which demonstrates that scenario.

In the initial release of Redis 6.2 setting a user to only allow pubsub access to a specific channel, and doing ACL SAVE, resulted in an assertion when ACL LOAD was used. This was later changed by #8723 (not yet released), but still not properly resolved (now it errors instead of crash). The problem is that the server that generates an ACL file, doesn't know what would be the setting of the acl-pubsub-default config in the server that will load it. so ACL SAVE needs to always start with resetchannels directive. This should still be compatible with old acl files (from redis 6.0), and ones from earlier versions of 6.2 that didn't mess with channels. Co-authored-by:

The tail size of c->reply is 16kb, but in the test only publish a few chars each time, due to a change in #8699, the obuf limit is now checked a new memory allocation is made, so this test would have sometimes failed to trigger a soft limit disconnection in time. The solution is to write bigger payloads to the output buffer, but still limit their rate (not more than 100k/s).

Fix "default" and overwritten / reset users will not have pubsub channels permissions by default. (#8723) Background: Redis 6.2 added ACL control for pubsub channels (#7993), which were supposed to be permissive by default to retain compatibility with redis 6.0 ACL. But due to a bug, only newly created users got this `acl-pubsub-default` applied, while overwritten (updated) users got reset to `resetchannels` (denied). Since the "default" user exists before loading the config file, any ACL change to it, results in an update / overwrite. So when a "default" user is loaded from config file or include ACL file with no channels related rules, the user will not have any permissions to any channels. But other users will have default permissions to any channels. When upgraded from 6.0 with config rewrite, this will lead to "default" user channels permissions lost. When users are loaded from include file, then call "acl load", users will also lost channels permissions. Similarly, the `reset` ACL rule, would have reset the user to be denied access to any channels, ignoring `acl-pubsub-default` and breaking compatibility with redis 6.0. The implication of this fix is that it regains compatibility with redis 6.0, but breaks compatibility with redis 6.2.0 and 2.0.1. e.g. after the upgrade, the default user will regain access to pubsub channels. Other changes: Additionally this commit rename server.acl_pubusub_default to server.acl_pubsub_default and fix typo in acl tests.

This command used to return the last scanned entry id as the cursor, instead of the next one to be scanned. so in the next call, the user could / should have sent `(cursor` and not just `cursor` if he wanted to avoid scanning the same record twice. Scanning the record twice would look odd if someone is checking what exactly was scanned, but it also has a side effect of incrementing the delivery count twice.

If GT/LT fails the operation we need to reply with nill (like failure due to NX). Other changes: Add the missing $encoding suffix to many zset tests Note: there's a behavior change just in case of INCR + GT/LT that fails. The old code was replying with the wrong (rejected) score, and now it'll reply with nil. Note that that's anyway a corner case so this "behavior change" shouldn't have too much affect. Using GT/LT with INCR has a predictable result even before we run the command (INCR GT will only only / always fail if the increment is negative).

Problem: Currently, when performing random distribution verification, we determine the probability of each element occurring in the sum, but the probability is only an estimate, these tests had rare sporadic failures, and we cannot verify what the probability of failure will be. Solution: Using the chi-square distribution instead of the original random distribution validation makes the test more reasonable and easier to find problems.

the bug was also discussed in #8716, and was solved in #8719, but incompletely: when the server is started, and the save option is default, if you issue the " config set save "" " to change the save option, and then issue the “config rewrite” command, the " save "" " won't be saved.

'processCommandAndResetClient' returns 1 if client is dead. It does it by checking if serve.current_client is NULL. On script timeout, Redis will re-enter 'processCommandAndResetClient' and when finish we will set server.current_client to NULL. This will cause later to falsely return 1 and think that the client that sent the timed-out script is dead (Redis to stop reading from the client buffer).

Add publish channel permissions check in processCommand. processCommand didn't check publish channel permissions, so we can queue a publish command in a transaction. But when exec the transaction, it will fail with -NOPERM. We also union keys/commands/channels permissions check togegher in ACLCheckAllPerm. Remove pubsubCheckACLPermissionsOrReply in publishCommand/subscribeCommand/psubscribeCommand. Always check permissions in processCommand/execCommand/ luaRedisGenericCommand.

* SLOWLOG didn't record anything for blocked commands because the client was reset and argv was already empty. there was a fix for this issue specifically for modules, now it works for all blocked clients. * The original command argv (before being re-written) was also reset before adding the slowlog on behalf of the blocked command. * Latency monitor is now updated regardless of the slowlog flags of the command or its execution (their purpose is to hide sensitive info from the slowlog, not hide the fact the latency happened). * Latency monitor now uses real_cmd rather than c->cmd (which may be different if the command got re-written, e.g. GEOADD) Changes: * Unify shared code between slowlog insertion in call() and updateStatsOnUnblock(), hopefully prevent future bugs from happening due to the later being overlooked. * Reset CLIENT_PREVENT_LOGGING in resetClient rather than after command processing. * Add a test for SLOWLOG and BLPOP Notes: - real_cmd == c->lastcmd, except inside MULTI and Lua. - blocked commands never happen in these cases (MULTI / Lua) - real_cmd == c->cmd, except for when the command is rewritten (e.g. GEOADD) - blocked commands (currently) are never rewritten - other than the command's CLIENT_PREVENT_LOGGING, and the execution flag CLIENT_PREVENT_LOGGING, other cases that we want to avoid slowlog are on AOF loading (specifically CMD_CALL_SLOWLOG will be off when executed from execCommand that runs from an AOF)

pcall function runs another LUA function in protected mode, this means that any error will be caught by this function and will not stop the LUA execution. The script kill mechanism uses error to stop the running script. Scripts that uses pcall can catch the error raise by the script kill mechanism, this will cause a script like this to be unkillable: local f = function() while 1 do redis.call('ping') end end while 1 do pcall(f) end The fix is, when we want to kill the script, we set the hook function to be invoked after each line. This will promise that the execution will get another error before it is able to enter the pcall function again.
