The nightly tests showed that the recent PR #12022 caused random failures in aof.tcl on checking RDB preamble inside an AOF file. Root cause: When checking RDB preamble in an AOF file, what's passed into redis_check_rdb is aof_filename, not aof_filepath. The newly introduced isFifo function does not check return status of the stat call and hence uses the uninitailized stat_p object. Fix: 1. Fix isFifo by checking stat call's return code. 2. Pass aof_filepath instead of aof_filename to redis_check_rdb. 3. move the FIFO check to rdb.c since the limitation is the re-opening of the file, and not anything specific about redis-check-rdb.

this pr fix two wrongs: 1. When client’s querybuf is pre-allocated for a fat argv, we need to update the querybuf_peak of the client immediately to completely avoid the unexpected shrinking of querybuf in the next clientCron (before data arrives to set the peak). 2. the protocol's bulklen does not include `\r\n`, but the allocation and the data we read does. so in `clientsCronResizeQueryBuffer`, the `resize` or `querybuf_peak` should add these 2 bytes. the first bug is likely to hit us on large payloads over slow connections, in which case transferring the payload can take longer and a cron event will be triggered (specifically if there are not a lot of clients)

When loading RDB over the named piped, redis_check_rdb() is hung at fopen, because fopen blocks until another process opens the FIFO for writing. The fix is to check if RDB is FIFO. If yes, return an error.

Currently LINSERT command does not have the test case coverage for following scenarios. 1. When key does not exist, it is considered an empty list and no operation is performed. 2. An error is returned when key exists but does not hold a list value. Added above two missing test cases for linsert command.

* Add RM_ReplyWithErrorFormat that can support format Reply with the error create from a printf format and arguments. If the error code is already passed in the string 'fmt', the error code provided is used, otherwise the string "-ERR " for the generic error code is automatically added. The usage is, for example: RedisModule_ReplyWithErrorFormat(ctx, "An error: %s", "foo"); RedisModule_ReplyWithErrorFormat(ctx, "-WRONGTYPE Wrong Type: %s", "foo"); The function always returns REDISMODULE_OK.

The MacOS CI in github actions often hangs without any logs. GH argues that it's due to resource utilization, either running out of disk space, memory, or CPU starvation, and thus the runner is terminated. This PR contains multiple attempts to resolve this: 1. introducing pause_process instead of SIGSTOP, which waits for the process to stop before resuming the test, possibly resolving race conditions in some tests, this was a suspect since there was one test that could result in an infinite loop in that case, in practice this didn't help, but still a good idea to keep. 2. disable the `save` config in many tests that don't need it, specifically ones that use heavy writes and could create large files. 3. change the `populate` proc to use short pipeline rather than an infinite one. 4. use `--clients 1` in the macos CI so that we don't risk running multiple resource demanding tests in parallel. 5. enable `--verbose` to be repeated to elevate verbosity and print more info to stdout when a test or a server starts.

We do have ZREMRANGEBYLEX tests, but it is a stress test marked with slow tag and then skipped in reply-schemas daily. In the past, we were able to succeed on a daily, i guess it was because there were some random command executions, such as corrupt-dump-fuzzy, which might call it. These test examples are taken from ZRANGEBYLEX basics test.

We use `zmalloc_usable_size()` everywhere to use memory blocks, but that is an abuse since the malloc_usable_size() isn't meant for this kind of use, it is for diagnostics only. That is also why the behavior is flaky when built with _FORTIFY_SOURCE, the compiler can sense that we reach outside the allocated block and SIGABRT. ### Solution If we need to use the additional memory we got, we need to use a dummy realloc with `alloc_size` attribute and no inlining, (see `extend_to_usable`) to let the compiler see the large of memory we need to use. This can either be an implicit call inside `z*usable` that returns the size, so that the caller doesn't have any other worry, or it can be a normal zmalloc call which means that if the caller wants to use zmalloc_usable_size it must also use extend_to_usable. ### Changes This PR does the following: 1) rename the current z[try]malloc_usable family to z[try]malloc_internal and don't expose them to users outside zmalloc.c, 2) expose a new set of `z[*]_usable` family that use z[*]_internal and `extend_to_usable()` implicitly, the caller gets the size of the allocation and it is safe to use. 3) go over all the users of `zmalloc_usable_size` and convert them to use the `z[*]_usable` family if possible. 4) in the places where the caller can't use `z[*]_usable` and store the real size, and must still rely on zmalloc_usable_size, we still make sure that the allocation used `z[*]_usable` (which has a call to `extend_to_usable()`) and ignores the returning size, this way a later call to `zmalloc_usable_size` is still safe. [4] was done for module.c and listpack.c, all the others places (sds, reply proto list, replication backlog, client->buf) are using [3]. Co-authored-by:

Add `RM_RdbLoad()` and `RM_RdbSave()` to load/save RDB files from the module API. In our use case, we have our clustering implementation as a module. As part of this implementation, the module needs to trigger RDB save operation at specific points. Also, this module delivers RDB files to other nodes (not using Redis' replication). When a node receives an RDB file, it should be able to load the RDB. Currently, there is no module API to save/load RDB files. This PR adds four new APIs: ```c RedisModuleRdbStream *RM_RdbStreamCreateFromFile(const char *filename); void RM_RdbStreamFree(RedisModuleRdbStream *stream); int RM_RdbLoad(RedisModuleCtx *ctx, RedisModuleRdbStream *stream, int flags); int RM_RdbSave(RedisModuleCtx *ctx, RedisModuleRdbStream *stream, int flags); ``` The first step is to create a `RedisModuleRdbStream` object. This PR provides a function to create RedisModuleRdbStream from the filename. (You can load/save RDB with the filename). In the future, this API can be extended if needed: e.g., `RM_RdbStreamCreateFromFd()`, `RM_RdbStreamCreateFromSocket()` to save/load RDB from an `fd` or a `socket`. Usage: ```c /* Save RDB */ RedisModuleRdbStream *stream = RedisModule_RdbStreamCreateFromFile("example.rdb"); RedisModule_RdbSave(ctx, stream, 0); RedisModule_RdbStreamFree(stream); /* Load RDB */ RedisModuleRdbStream *stream = RedisModule_RdbStreamCreateFromFile("example.rdb"); RedisModule_RdbLoad(ctx, stream, 0); RedisModule_RdbStreamFree(stream); ```

This test produces 1GB of data and moves it around, and was expecting less than 500kb to be present in the system page cache. It sometimes fails with up to some 6mb in the page cache (0 in the actual RDB files), increasing the threshold. It looks like some background tasks in the container are occupying the page cache. It is safe to ignore the above since we also explicitly check the pages of our dump.rdb are not cached (matching `vmtouch -v` to `0%`). An additional fix is to match ` 0%` (add space), so that we don't successfully match `10%`. details in https://github.com/redis/redis/pull/11818

Fix the following config file error ``` *** FATAL CONFIG FILE ERROR (Redis 6.2.7) *** Reading the configuration file, at line 152 >>> 'sentinel known-replica XXXX 127.0.0.1 5001' Duplicate hostname and port for replica. ``` that is happening when a user uses the legacy key "known-slave" in the config file and a config rewrite occurs. The config rewrite logic won't replace the old line "sentinel known-slave XXXX 127.0.0.1 5001" and would add a new line with "sentinel known-replica XXXX 127.0.0.1 5001" which results in the error above "Duplicate hostname and port for replica." example: Current sentinal.conf ``` ... sentinel known-slave XXXX 127.0.0.1 5001 sentinel example-random-option X ... ``` after the config rewrite logic runs: ``` .... sentinel known-slave XXXX 127.0.0.1 5001 sentinel example-random-option X # Generated by CONFIG REWRITE sentinel known-replica XXXX 127.0.0.1 5001 ``` This bug only exists in Redis versions >=6.2 because prior to that it was hidden by the effects of this bug https://github.com/redis/redis/issues/5388 that was fixed in https://github.com/redis/redis/pull/8271 and was released in versions >=6.2

In cluster mode, when a node restart as a replica, it doesn't immediately sync with the master, replication is enabled in clusterCron. It means that sometime server.masterhost is NULL and we wrongly judge it in beforeSleep. In this case, we may trigger a fast activeExpireCycle in beforeSleep, but the node's flag is actually a replica, that can lead to data inconsistency. In this PR, we use iAmMaster to replace the `server.masterhost == NULL` This is an overlook in #7001, and more discussion in #11783.

The existing logic for killing pub-sub clients did not handle the `allchannels` permission correctly. For example, if you: ACL SETUSER foo allchannels Have a client authenticate as the user `foo` and subscribe to a channel, and then: ACL SETUSER foo resetchannels The subscribed client would not be disconnected, though new clients under that user would be blocked from subscribing to any channels. This was caused by an incomplete optimization in `ACLKillPubsubClientsIfNeeded` checking whether the new channel permissions were a strict superset of the old ones.

Now that the command argument specs are available at runtime (#9656), this PR addresses #8084 by implementing a complete solution for command-line hinting in `redis-cli`. It correctly handles nearly every case in Redis's complex command argument definitions, including `BLOCK` and `ONEOF` arguments, reordering of optional arguments, and repeated arguments (even when followed by mandatory arguments). It also validates numerically-typed arguments. It may not correctly handle all possible combinations of those, but overall it is quite robust. Arguments are only matched after the space bar is typed, so partial word matching is not supported - that proved to be more confusing than helpful. When the user's current input cannot be matched against the argument specs, hinting is disabled. Partial support has been implemented for legacy (pre-7.0) servers that do not support `COMMAND DOCS`, by falling back to a statically-compiled command argument table. On startup, if the server does not support `COMMAND DOCS`, `redis-cli` will now issue an `INFO SERVER` command to retrieve the server version (unless `HELLO` has already been sent, in which case the server version will be extracted from the reply to `HELLO`). The server version will be used to filter the commands and arguments in the command table, removing those not supported by that version of the server. However, the static table only includes core Redis commands, so with a legacy server hinting will not be supported for module commands. The auto generated help.h and the scripts that generates it are gone. Command and argument tables for the server and CLI use different structs, due primarily to the need to support different runtime data. In order to generate code for both, macros have been added to `commands.def` (previously `commands.c`) to make it possible to configure the code generation differently for different use cases (one linked with redis-server, and one with redis-cli). Also adding a basic testing framework for the command hints based on new (undocumented) command line options to `redis-cli`: `--test_hint 'INPUT'` prints out the command-line hint for a given input string, and `--test_hint_file <filename>` runs a suite of test cases for the hinting mechanism. The test suite is in `tests/assets/test_cli_hint_suite.txt`, and it is run from `tests/integration/redis-cli.tcl`. Co-authored-by:

In #11012, we changed the way command durations were computed to handle the same command being executed multiple times. This commit fixes some misses from that commit. * Wait commands were not correctly reporting their duration if the timeout was reached. * Multi/scripts/and modules with RM_Call were not properly resetting the duration between inner calls, leading to them reporting cumulative duration. * When a blocked client is freed, the call and duration are always discarded. This commit also adds an assert if the duration is not properly reset, potentially indicating that a report to call statistics was missed. The assert potentially be removed in the future, as it's mainly intended to detect misses in tests.

This is an attempt to normalize/formalize command summaries. Main actions performed: * Starts with the continuation of the phrase "The XXXX command, when called, ..." for user commands. * Starts with "An internal command...", "A container command...", etc... when applicable. * Always uses periods. * Refrains from referring to other commands. If this is needed, backquotes should be used for command names. * Tries to be very clear about the data type when applicable. * Tries to mention additional effects, e.g. "The key is created if it doesn't exist" and "The set is deleted if the last member is removed." * Prefers being terse over verbose. * Tries to be consistent.

This PR fix several unrelated bugs that were discovered by the same set of tests (WAITAOF tests in #11713), could make the `WAITAOF` test hang. The change in `backgroundRewriteDoneHandler` is about MP-AOF. That leftover / old code assumes that we started a new AOF file just now (when we have a new base into which we're gonna incrementally write), but the fact is that with MP-AOF, the fork done handler doesn't really affect the incremental file being maintained by the parent process, there's no reason to re-issue `SELECT`, and no reason to update any of the fsync variables in that flow. This should have been deleted with MP-AOF (introduced in #9788, 7.0). The damage is that the update to `aof_fsync_offset` will cause us to miss an fsync in `flushAppendOnlyFile`, that happens if we stop write commands in `AOF_FSYNC_EVERYSEC` while an AOFRW is in progress. This caused a new `WAITAOF` test to sometime hang forever. Also because of MP-AOF, we needed to change `aof_fsync_offset` to `aof_last_incr_fsync_offset` and match it to `aof_last_incr_size` in `flushAppendOnlyFile`. This is because in the past we compared `aof_fsync_offset` and `aof_current_size`, but with MP-AOF it could be the total AOF file will be smaller after AOFRW, and the (already existing) incr file still has data that needs to be fsynced. The change in `flushAppendOnlyFile`, about the `AOF_FSYNC_ALWAYS`, it is follow #6053 (the details is in #5985), we also check `AOF_FSYNC_ALWAYS` to handle a case where appendfsync is changed from everysec to always while there is data that's written but not yet fsynced.

The sanity check test intention was to detect that when a command is added to sentinel it is on purpose. This test is easily broken, like CLIENT SETINFO introduced by #11758. We replace it with a test that validates that a few specific commands are either there or missing (to test the infrastructure works correctly).

This PR allows clients to send information about the client library to redis to be displayed in CLIENT LIST and CLIENT INFO. Currently supports: `CLIENT [lib-name | lib-ver] <value>` Client libraries are expected to pipeline these right after AUTH, and ignore the failure in case they're talking to an older version of redis. These will be shown in CLIENT LIST and CLIENT INFO as: * `lib-name` - meant to hold the client library name. * `lib-ver` - meant to hold the client library version. The values cannot contain spaces, newlines and any wild ASCII characters, but all other normal chars are accepted, e.g `.`, `=` etc (same as CLIENT NAME). The RESET command does NOT clear these, but they can be cleared to the default by sending a command with a blank string. Co-authored-by:

This allows modules to register commands to existing ACL categories and blocks the creation of [sub]commands, datatypes and registering the configs outside of the OnLoad function. For allowing modules to register commands to existing ACL categories, This PR implements a new API int RM_SetCommandACLCategories() which takes a pointer to a RedisModuleCommand and a C string aclflags containing the set of space separated ACL categories. Example, 'write slow' marks the command as part of the write and slow ACL categories. The C string aclflags is tokenized by implementing a helper function categoryFlagsFromString(). Theses tokens are matched and the corresponding ACL categories flags are set by a helper function matchAclCategoriesFlags. The helper function categoryFlagsFromString() returns the corresponding categories_flags or returns -1 if some token not processed correctly. If the module contains commands which are registered to existing ACL categories, the number of [sub]commands are tracked by num_commands_with_acl_categories in struct RedisModule. Further, the allowed command bit-map of the existing users are recomputed from the command_rules list, by implementing a function called ACLRecomputeCommandBitsFromCommandRulesAllUsers() for the existing users to have access to the module commands on runtime. ## Breaking change This change requires that registering commands and subcommands only occur during a modules "OnLoad" function, in order to allow efficient recompilation of ACL bits. We also chose to block registering configs and types, since we believe it's only valid for those to be created during onLoad. We check for this onload flag in struct RedisModule to check if the call is made from the OnLoad function. Co-authored-by:

I saw this error once, in the FreeBSD Daily CI: ``` *** [err]: Temp rdb will be deleted if we use bg_unlink when shutdown in tests/unit/shutdown.tcl Expected [file exists /xxx/temp-10336.rdb] (context: type eval line 15 cmd {assert {[file exists $temp_rdb]}} proc ::test) ``` The log shows that bgsave was executed, and it was successfully executed in the end: ``` Starting test Temp rdb will be deleted if we use bg_unlink when shutdown in tests/unit/shutdown.tcl 10251:M 22 Feb 2023 11:37:25.441 * Background saving started by pid 10336 10336:C 22 Feb 2023 11:37:27.949 * DB saved on disk 10336:C 22 Feb 2023 11:37:27.949 * Fork CoW for RDB: current 0 MB, peak 0 MB, average 0 MB 10251:M 22 Feb 2023 11:37:28.060 * Background saving terminated with success ``` There may be two reasons: 1. The child process has been created, but it has not created the temp rdb file yet, so [file exists $temp_rdb] check failed. 2. The child process bgsave has been executed successfully and the temp file has been deleted, so [file exists $temp_rdb] check failed. From the logs pint, it should be the case 2, case 1 is too extreme, set rdb-key-save-delay to a higher value to ensure bgsave does not succeed early to avoid this case.
