The test failed from time to time on Github actions. We think it's possible that on the module's blocking timeout time tracking test, the timeout is happening prior we issue the RedisModule_BlockedClientMeasureTimeStart(bc) on the background thread. If that is the case one possible solution is to increase the timeout. Increasing to 200ms to 500ms to see if nightly stops failing.

Without this fix, RM_ZsetRem can leave empty sorted sets which are not allowed to exist. Removing from a sorted set while iterating seems to work (while inserting causes failed assetions). RM_ZsetRangeEndReached is modified to return 1 if the key doesn't exist, to terminate iteration when the last element has been removed.

* Add bash temporarily to allow sentinel fd leaks test to run. * Use vmactions-freebsd rdist sync to work around bind permission denied and slow execution issues. * Upgrade to tcl8.6 to be aligned with latest Ubuntu envs. * Concat all command executions to avoid ignoring failures. * Skip intensive fuzzer on FreeBSD. For some yet unknown reason, generate_fuzzy_traffic_on_key causes TCL to significantly bloat on FreeBSD resulting with out of memory.

These tests are not yet stable. on github actions they show some false leaks.

* The corrupt dump fuzzer found a division by zero. * in some cases the random fields from the HRANDFIELD tests produced fields with newlines and other special chars (due to \ char), this caused the TCL tests to see a bulk response that has a newline in it and add {} around it, later it can think this is a nested list. in fact the `alpha` random string generator isn't using spaces and newlines, so it should not use `\` either.

Enabled background and reply time tracking on blocked on keys/blocked on background work clients (#7491) This commit enables tracking time of the background tasks and on replies, opening the door for properly tracking commands that rely on blocking / background work via the slowlog, latency history, and commandstats. Some notes: - The time spent blocked waiting for key changes, or blocked on synchronous replication is not accounted for. - **This commit does not affect latency tracking of commands that are non-blocking or do not have background work.** ( meaning that it all stays the same with exception to `BZPOPMIN`,`BZPOPMAX`,`BRPOP`,`BLPOP`, etc... and module's commands that rely on background threads ). - Specifically for latency history command we've added a new event class named `command-unblocking` that will enable latency monitoring on commands that spawn background threads to do the work. - For blocking commands we're now considering the total time of a command as the time spent on call() + the time spent on replying when unblocked. - For Modules commands that rely on background threads we're now considering the total time of a command as the time spent on call (main thread) + the time spent on the background thread ( if marked within `RedisModule_MeasureTimeStart()` and `RedisModule_MeasureTimeEnd()` ) + the time spent on replying (main thread) To test for this feature we've added a `unit/moduleapi/blockonbackground` test that relies on a module that blocks the client and sleeps on the background for a given time. - check blocked command that uses RedisModule_MeasureTimeStart() is tracking background time - check blocked command that uses RedisModule_MeasureTimeStart() is tracking background time even in timeout - check blocked command with multiple calls RedisModule_MeasureTimeStart() is tracking the total background time - check blocked command without calling RedisModule_MeasureTimeStart() is not reporting background time

New commands: `HRANDFIELD [<count> [WITHVALUES]]` `ZRANDMEMBER [<count> [WITHSCORES]]` Algorithms are similar to the one in SRANDMEMBER. Both return a simple bulk response when no arguments are given, and an array otherwise. In case values/scores are requested, RESP2 returns a long array, and RESP3 a nested array. note: in all 3 commands, the only option that also provides random order is the one with negative count. Changes to SRANDMEMBER * Optimization when count is 1, we can use the more efficient algorithm of non-unique random * optimization: work with sds strings rather than robj Other changes: * zzlGetScore: when zset needs to convert string to double, we use safer memcpy (in case the buffer is too small) * Solve a "bug" in SRANDMEMBER test: it intended to test a positive count (case 3 or case 4) and by accident used a negative count Co-authored-by:

APIs added for these stream operations: add, delete, iterate and trim (by ID or maxlength). The functions are prefixed by RM_Stream. * RM_StreamAdd * RM_StreamDelete * RM_StreamIteratorStart * RM_StreamIteratorStop * RM_StreamIteratorNextID * RM_StreamIteratorNextField * RM_StreamIteratorDelete * RM_StreamTrimByLength * RM_StreamTrimByID The type RedisModuleStreamID is added and functions for converting from and to RedisModuleString. * RM_CreateStringFromStreamID * RM_StringToStreamID Whenever the stream functions return REDISMODULE_ERR, errno is set to provide additional error information. Refactoring: The zset iterator fields in the RedisModuleKey struct are wrapped in a union, to allow the same space to be used for type- specific info for streams and allow future use for other key types.

This is both a bugfix and an enhancement. Internally, Sentinel relies entirely on IP addresses to identify instances. When configured with a new master, it also requires users to specify and IP and not hostname. However, replicas may use the replica-announce-ip configuration to announce a hostname. When that happens, Sentinel fails to match the announced hostname with the expected IP and considers that a different instance, triggering reconfiguration, etc. Another use case is where TLS is used and clients are expected to match the hostname to connect to with the certificate's SAN attribute. To properly implement this configuration, it is necessary for Sentinel to redirect clients to a hostname rather than an IP address. The new 'resolve-hostnames' configuration parameter determines if Sentinel is willing to accept hostnames. It is set by default to no, which maintains backwards compatibility and avoids unexpected DNS resolution delays on systems with DNS configuration issues. Internally, Sentinel continues to identify instances by their resolved IP address and will also report the IP by default. The new 'announce-hostnames' parameter determines if Sentinel should prefer to announce a hostname, when available, rather than an IP address. This applies to addresses returned to clients, as well as their representation in the configuration file, REPLICAOF configuration commands, etc. This commit also introduces SENTINEL CONFIG GET and SENTINEL CONFIG SET which can be used to introspect or configure global Sentinel configuration that was previously was only possible by directly accessing the configuration file and possibly restarting the instance.

if option `set-proc-title' is no, then do nothing for proc title. The reason has been explained long ago, see following: We update redis to 2.8.8, then found there are some side effect when redis always change the process title. We run several slave instance on one computer, and all these salves listen on unix socket only, then ps will show: 1 S redis 18036 1 0 80 0 - 56130 ep_pol 14:02 ? 00:00:31 /usr/sbin/redis-server *:0 1 S redis 23949 1 0 80 0 - 11074 ep_pol 15:41 ? 00:00:00 /usr/sbin/redis-server *:0 for redis 2.6 the output of ps is like following: 1 S redis 18036 1 0 80 0 - 56130 ep_pol 14:02 ? 00:00:31 /usr/sbin/redis-server /etc/redis/a.conf 1 S redis 23949 1 0 80 0 - 11074 ep_pol 15:41 ? 00:00:00 /usr/sbin/redis-server /etc/redis/b.conf Later is more informational in our case. The situation is worse when we manage the config and process running state by salt. Salt check the process by running "ps | grep SIG" (for Gentoo System) to check the running state, where SIG is the string to search for when looking for the service process with ps. Previously, we define sig as "/usr/sbin/redis-server /etc/redis/a.conf". Since the ps output is identical for our case, so we have no way to check the state of specified redis instance. So, for our case, we prefer the old behavior, i.e, do not change the process title for the main redis process. Or add an option such as "set-proc-title [yes|no]" to control this behavior.

This commit introduces two new command and two options for an existing command GETEX <key> [PERSIST][EX seconds][PX milliseconds] [EXAT seconds-timestamp] [PXAT milliseconds-timestamp] The getexCommand() function implements extended options and variants of the GET command. Unlike GET command this command is not read-only. Only one of the options can be used at a given time. 1. PERSIST removes any TTL associated with the key. 2. EX Set expiry TTL in seconds. 3. PX Set expiry TTL in milliseconds. 4. EXAT Same like EX instead of specifying the number of seconds representing the TTL (time to live), it takes an absolute Unix timestamp 5. PXAT Same like PX instead of specifying the number of milliseconds representing the TTL (time to live), it takes an absolute Unix timestamp Command would return either the bulk string, error or nil. GETDEL <key> Would delete the key after getting. SET key value [NX] [XX] [KEEPTTL] [GET] [EX <seconds>] [PX <milliseconds>] [EXAT <seconds-timestamp>][PXAT <milliseconds-timestamp>] Two new options added here are EXAT and PXAT Key implementation notes - `SET` with `PX/EX/EXAT/PXAT` is always translated to `PXAT` in `AOF`. When relative time is specified (`PX/EX`), replication will always use `PX`. - `setexCommand` and `psetexCommand` would no longer need translation in `feedAppendOnlyFile` as they are modified to invoke `setGenericCommand ` with appropriate flags which will take care of correct AOF translation. - `GETEX` without any optional argument behaves like `GET`. - `GETEX` command is never propagated, It is either propagated as `PEXPIRE[AT], or PERSIST`. - `GETDEL` command is propagated as `DEL` - Combined the validation for `SET` and `GETEX` arguments. - Test cases to validate AOF/Replication propagation

It was confusing as to why these don't return a map type. the reason is that order matters, so we need to make sure the client library knows to respect it. Added comments in the implementation and tests to cover it.

This commit fixes a well known and an annoying issue in Sentinel mode. Cause of this issue: Currently, Redis rewrite process works well in server mode, however in sentinel mode, the sentinel config has variant semantics for different configurations, in example configuration https://github.com/redis/redis/blob/unstable/sentinel.conf, we put comments on these. However the rewrite process only treat the sentinel config as a single option. During rewrite process, it will mess up with the lines and comments. Approaches: In order to solve this issue, we need to differentiate different subconfig options in sentinel separately, for example, sentinel monitor <master-name> <ip> <redis-port> <quorum> we can treat it as sentinel monitor option, instead of the sentinel option. This commit also fixes the dependency issue when putting configurations in sentinel.conf. For example before this commit,we must put `sentinel monitor <master-name> <ip> <redis-port> <quorum>` before `sentinel auth-pass <master-name> <password>` for a single master, otherwise the server cannot start and will return error. This commit fixes this issue, as long as the monitoring master was configured, no matter the sequence is, the sentinel can start and run properly.

some tests use attach_to_replication_stream to watch what's propagated to replicas, but in some cases the periodic ping may slip in and fail the test. we disable that ping by setting the period to once an hour (tests should not run for that long). other change is so that the next time this oom-score-adj test fails, we'll see the value (assert_equals prints it)

BLPOP and other blocking list commands can only block on empty keys and LPUSH only wakes up clients when the list is created. Using the module API, it's possible to block on a non-empty key. Unblocking a client blocked on a non-empty list (or zset) can only be done using RedisModule_SignalKeyAsReady(). This commit tests it.

the test was misleading because the module would actually woke up on a wrong type and re-blocked, while the test name suggests the module doesn't not wake up at all on a wrong type.. i changed the name of the test + added verification that indeed the module wakes up and gets re-blocked after it understand it's the wrong type

Sentinel uses execve to run scripts, so it needs to use FD_CLOEXEC on all file descriptors, so that they're not accessible by the script it runs. This commit includes a change to the sentinel tests, which verifies no FDs are left opened when the script is executed.

This commit adds tests to make sure that relative and absolute expire commands are propagated as is to replicas and stop any future attempt to change that without a proper discussion. see #8327 and #5171 Additionally it slightly improve the AOF test that tests the opposite (always propagating absolute times), by covering more commands, and shaving 2 seconds from the test time.

This was a regression from #7625 (only in 6.2 RC2). This makes it possible again to implement blocking list and zset commands using the modules API. This commit also includes a test case for the reverse: A module unblocks a client blocked on BLPOP by inserting elements using RedisModule_ListPush(). This already works, but it was untested.
