Update adds a general source for retrieving a monotonic time. In addition, AE has been updated to utilize the new monotonic clock for timer processing. This performance improvement is **not** enabled in a default build due to various H/W compatibility concerns, see README.md for details. It does however change the default use of gettimeofday with clock_gettime and somewhat improves performance. This update provides the following 1. An interface for retrieving a monotonic clock. getMonotonicUs returns a uint64_t (aka monotime) with the number of micro-seconds from an arbitrary point. No more messing with tv_sec/tv_usec. Simple routines are provided for measuring elapsed milli-seconds or elapsed micro-seconds (the most common use case for a monotonic timer). No worries about time moving backwards. 2. High-speed assembler implementation for x86 and ARM. The standard method for retrieving the monotonic clock is POSIX.1b (1993): clock_gettime(CLOCK_MONOTONIC, timespec*). However, most modern processors provide a constant speed instruction clock which can be retrieved in a fraction of the time that it takes to call clock_gettime. For x86, this is provided by the RDTSC instruction. For ARM, this is provided by the CNTVCT_EL0 instruction. As a compile-time option, these high-speed timers can be chosen. (Default is POSIX clock_gettime.) 3. Refactor of event loop timers. The timer processing in ae.c has been refactored to use the new monotonic clock interface. This results in simpler/cleaner logic and improved performance.

65a3307b (released in 6.0.6) has a side effect, when processCommand rejects a command with pre-made shared object error string, it trims the newlines from the end of the string. if that string is later used with addReply, the newline will be missing, breaking the protocol, and leaving the client hung. It seems that the only scenario which this happens is when replying with -LOADING to some command, and later using that reply from the CONFIG SET command (still during loading). this will result in hung client. Refactoring the code in order to avoid trimming these newlines from shared string objects, and do the newline trimming only in other cases where it's needed. Co-authored-by:

During a long AOF or RDB loading, the memory stats were not updated, and INFO would return stale data, specifically about fragmentation and RSS. In the past some of these were sampled directly inside the INFO command, but were moved to cron as an optimization. This commit introduces a concept of loadingCron which should take some of the responsibilities of serverCron. It attempts to limit it's rate to approximately the server Hz, but may not be very accurate. In order to avoid too many system call, we use the cached ustime, and also make sure to update it in both AOF loading and RDB loading inside processEventsWhileBlocked (it seems AOF loading was missing it).

If the server gets MULTI command followed by only read commands, and right before it gets the EXEC it reaches OOM, the client will get OOM response. So, from now on, it will get OOM response only if there was at least one command that was tagged with `use-memory` flag

A first step to enable a consistent full percentile analysis on query latency so that we can fully understand the performance and stability characteristics of the redis-server system we are measuring. It also improves the instantaneous reported metrics, and the csv output format.

Otherwise, it is treated as a single allocation and freed synchronously. The following logic is used for estimating the effort in constant-ish time complexity: 1. Check the number of nodes. 1. Add an allocation for each consumer group registered inside the stream. 1. Check the number of PELs in the first CG, and then add this count times the number of CGs. 1. Check the number of consumers in the first CG, and then add this count times the number of CGs.

The previous fix using _Atomic was insufficient, since we check and set it in different places. The implications of this bug are just that a portion of the bug report will be shown twice, in the race case of two concurrent crashes.

In case the redis is about to return broken reply we want to crash with assert so that we are notified about the bug. see #7687.

When calling to LPOS command when RANK is higher than matches, the return value is non valid response. For example: ``` LPUSH l a :1 LPOS l b RANK 5 COUNT 10 *-4 ``` It may break client-side parser. Now, we count how many replies were replied in the array. ``` LPUSH l a :1 LPOS l b RANK 5 COUNT 10 *0 ```

It was also using the wrong struct, but luckily RedisModuleFlushInfo and RedisModuleLoadingProgress are identical.

After fork, the child process(redis-aof-rewrite) will get the fd opened by the parent process(redis), when redis killed by kill -9, it will not graceful exit(call prepareForShutdown()), so redis-aof-rewrite thread may still alive, the fd(lock) will still be held by redis-aof-rewrite thread, and redis restart will fail to get lock, means fail to start. This issue was causing failures in the cluster tests in github actions. Co-authored-by:

65a3307b added rejectCommand which takes an robj reply and passes it through addReplyErrorSafe to addReplyErrorLength. The robj contains newline at it's end, but addReplyErrorSafe converts it to spaces, and passes it to addReplyErrorLength which adds the protocol newlines. The result was that most error replies (like OOM) had extra two trailing spaces in them.

Avoid re-configuring (and validating) SSL/TLS configuration on `CONFIG SET` when TLS is not actively enabled for incoming connections, cluster bus or replication. This fixes failures when tests run without `--tls` on binaries that were built with TLS support. An additional benefit is that it's now possible to perform a multi-step configuration process while TLS is disabled. The new configuration will be verified and applied only when TLS is effectively enabled.

This resolves an issue with sentinel that was created when hiredis was recently updated. this was due to sds symbol names clashing, since hiredis now includes different implementation of sdsrange than the one in redis. The state of things is that redis-benchamrk and redis-cli include only hiredis sds implementation. redis-cli even operates (calls sdscatlen) on sds that's allocated by hiredis. Sentinel however has both implementations of the sds library in it (now each with it's own unique symbols).

In order to keep the redismodule.h self-contained but still usable with gcc v10 and later, annotate each API function tentative definition with the __common__ attribute. This avoids the 'multiple definition' errors modules will otherwise see for all API functions at link time. Further details at gcc.gnu.org/gcc-10/porting_to.html Turn the existing __attribute__ ((unused)), ((__common__)) and ((print)) annotations into conditional macros for any compilers not accepting this syntax. These macros only expand to API annotations under gcc. Provide a pre- and post- macro for every API function, so that they can be defined differently by the file that includes redismodule.h. Removing REDISMODULE_API_FUNC in the interest of keeping the function declarations readable. Co-authored-by:

Client that issued WAIT last will most likely have the highest replication offset, so imagine a probably common case where all clients are waiting for the same number of replicas. we prefer the loop to start from the last client (one waiting for the highest offset), so that the optimization in the function will call replicationCountAcksByOffset for each client until it found a good one, and stop calling it for the rest of the clients. the way the loop was implemented would mean that in such case it is likely to call replicationCountAcksByOffset for all clients. Note: the change from > to >= is not directly related to the above. Co-authored-by:

Add Linux kernel OOM killer control option. This adds the ability to control the Linux OOM killer oom_score_adj parameter for all Redis processes, depending on the process role (i.e. master, replica, background child). A oom-score-adj global boolean flag control this feature. In addition, specific values can be configured using oom-score-adj-values if additional tuning is required.
