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:

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.

Added RedisModule_HoldString that either returns a shallow copy of the given String (by increasing the String ref count) or a new deep copy of String in case its not possible to get a shallow copy. Co-authored-by:

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:

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 (cherry picked from commit b7289e91)

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. (cherry picked from commit 5b0a06af)

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. (cherry picked from commit 8b428cf0)

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 ``` (cherry picked from commit 9204a9b2)

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. (cherry picked from commit cdd925b2)

The `REDISMODULE_CLIENTINFO_FLAG_SSL` flag was already a part of the `RedisModuleClientInfo` structure but was not implemented. (cherry picked from commit 64c360c5)

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. (cherry picked from commit fb2a94af)

In redismodule.h, RedisModule_DeauthenticateAndCloseClient returns void `void REDISMODULE_API_FUNC(RedisModule_DeauthenticateAndCloseClient)(RedisModuleCtx *ctx, uint64_t client_id);` But in module.c, RM_DeauthenticateAndCloseClient returns int `int RM_DeauthenticateAndCloseClient(RedisModuleCtx *ctx, uint64_t client_id)` It it safe to change return value from `void` to `int` from the user's perspective.
