if resp aof contains "file", it will be considered a manifest file and
the check will fail:

```
In #12951, if the preamble aof also contains it, it will also fail.
Fixes#12951.
the bug was happening if the the word "file" is mentioned
in the first 1024 lines of the AOF. and now as soon as it finds
a non-comment line it'll break (if it contains "file" or doesn't)

Since lua_Number is not explicitly an integer or a double, we need to
make an effort
to convert it as an integer when that's possible, since the string could
later be used
in a context that doesn't support scientific notation (e.g. 1e9 instead
of 100000000).
Since fpconv_dtoa converts numbers with the equivalent of `%f` or `%e`,
which ever is shorter,
this would break if we try to pass a long integer number to a command
that takes integer.
we'll get an implicit conversion to string in Lua, and then the parsing
in getLongLongFromObjectOrReply will fail.

The --count option for redis-cli has been released in redis 7.2.
https://github.com/redis/redis/pull/12042
But I have found in code, that some logic was missing for using this
'count' option.
```
static redisReply *sendScan(unsigned long long *it) {
redisReply *reply;
if (config.pattern)
reply = redisCommand(context, "SCAN %llu MATCH %b COUNT %d",
*it, config.pattern, sdslen(config.pattern), config.count);
else
reply = redisCommand(context,"SCAN %llu",*it);
```
The intention was being able to using scan count.
But in this case, the --count will be only applied when 'pattern' is
declared.
So, I had fix it simply, to be worked properly - even if --pattern
option is not being used.
I tested it simply with time() command several times, and I could see it
works as intended with this commit.
The examples of test results are below:
```
# unstable build

Fix two crash introducted by #12955
When a quicklist node can't be inserted and split, we eventually merge
the current node with its neighboring
nodes after inserting, and compress the current node and its siblings.
1. When the current node is merged with another node, the current node
may become invalid and can no longer be used.
Solution: let `_quicklistMergeNodes()` return the merged nodes.
3. If the current node is a LZF quicklist node, its recompress will be
1. If the split node can be merged with a sibling node to become head or
tail, recompress may cause the head and tail to be compressed, which is
not allowed.
Solution: always recompress to 0 after merging.

Fix#12864
The main reason for this crash is that when replacing a element of a
quicklist packed node with lpReplace() method,
if the final size is larger than 4GB, lpReplace() will fail and returns
NULL, causing `node->entry` to be incorrectly set to NULL.
Since the inserted data is not a large element, we can't just replace it
like a large element, first quicklistInsertAfter()
and then quicklistDelIndex(), because the current node may be merged and
invalidated in quicklistInsertAfter().
The solution of this PR:
When replacing a node fails (listpack exceeds 4GB), split the current
node, create a new node to put in the middle, and try to merge them.
This is the same as inserting a large element.
In the worst case, its size will not exceed 4GB.

because of the re-processing command, we will recalculate the block

This commit add a new CLIENT_REPROCESSING_COMMAND clent flag, explicitly
let the command know that it is being re-processed, later in

`REGISTER_API` is supposed to register two functions: one starts with

`unstable` branch. However there was a copy-paste mistake during
backporting it to 7.2. This caused modules built with `valkeymodule-rs`

enabled by default) with older Redis cluster (< 7.0 - extensions not
handled) .
With some of the extensions enabled by default in 7.2 version, new nodes
running 7.2 and above start sending out larger clusterbus message
payload including the ping extensions. This caused an incompatibility
with node running engine versions < 7.0. Old nodes (< 7.0) would receive
the payload from new nodes (> 7.2) would observe a payload length
(totlen) > (estlen) and would perform an early exit and won't process
the message.
This fix introduces a flag `extensions_supported` on the clusterMsg
indicating the sender node can handle extensions parsing. Once, a
receiver nodes receives a message with this flag set to 1, it would
update clusterNode new field extensions_supported and start sending out
extensions if it has any.
This PR also introduces a DEBUG sub command to enable/disable cluster
message extensions `process-clustermsg-extensions` feature.
Note: A successful `PING`/`PONG` is required as a sender for a given
node to be marked as `extensions_supported` and then extensions message
will be sent to it. This could cause a slight delay in receiving the
extensions message(s).
TCL test verifying the cluster state is healthy irrespective of
enabling/disabling cluster message extensions feature.

Adds a new make variable called `USE_REDIS_SYMLINKS`, with default value
`yes`. If yes, then `make install` creates additional symlinks to the
installed binaries:
* `valkey-server`
* `valkey-cli`
* `valkey-benchmark`
* `valkey-check-rdb`
* `valkey-check-aof`
* `valkey-sentinel`
The names of the symlinks are the legacy redis binary names
(`redis-server`, etc.). The purpose is to provide backward compatibility
for scripts expecting the these filenames. The symlinks are installed in
the same directory as the binaries (typically `/usr/local/bin/` or
similar).
Similarly, `make uninstall` removes these symlinks if
`USE_REDIS_SYMLINKS` is `yes`.
This is described in a note in README.md.

`CONFIG SET oom-score-adj handles configuration failures` test failed in
some CI jobs today.
Failed CI: https://github.com/redis/redis/actions/runs/8152519326
Not sure why the github action's docker image perssions have changed,
but the issue is similar to #12887,
where we can't assume the range of oom_score_adj that a user can change.
## Solution:
Modify the way of determining whether the current user has no privileges
or not,
instead of relying on whether the user id is 0 or not.
Fix#12792
On ubuntu 23(lunar), non-root users will not be allowed to change the
oom_score_adj of a process to a value that is too low.
Since terminal's default oom_score_adj is 200, if we run the test on
terminal, we won't be able to set the oom_score_adj of the redis process
to 9 or 22, which is too low.
Reproduction on ubuntu 23(lunar) terminal:
```sh
$ cat /proc/`pgrep redis-server`/oom_score_adj
200
$ echo 100 > /proc/`pgrep redis-server`/oom_score_adj
# success without error
$ echo 99 > /proc/`pgrep redis-server`/oom_score_adj
echo: write error: Permission denied
```
As from the output above, we can only set the minimum oom score of redis
processes to 100.
By modifying the test, make oom_score_adj only increase upwards and not
decrease.

Crash reported in #12695. In the process of upgrading the cluster from
7.0 to 7.2, because the 7.0 nodes will not gossip shard id, in 7.2 we
will rely on shard id to build the server.cluster->shards dict.
In some cases, for example, the 7.0 master node and the 7.2 replica node.
From the view of 7.2 replica node, the cluster->shards dictionary does not
have its master node. In this case calling CLUSTER SHARDS on the 7.2 replica
node may crash.
We should fix the underlying assumption of updateShardId, which is that the
shard dict should be always in sync with the node's shard_id. The fix was
suggested by PingXie, see more details in #12695.
(cherry picked from commit 5b0c6a8255af2d0e4921fa60d631bb3857724cb6)
If there are nodes in the cluster that do not support shard-id, they
will gossip shard-id. From the perspective of nodes that support shard-id,
their shard-id is meaningless (since shard-id is randomly generated when
we create a node.)
Nodes that support shard-id will save the shard-id information in nodes.conf.
If the node is restarted according to nodes.conf, the server will report a
corrupted cluster config file error. Because auxShardIdSetter will reject
configurations with inconsistent master-replica shard-ids.
A cluster-wide consensus for the node's shard_id is not necessary. The key
is maintaining consistency of the shard_id on each individual 7.2 node.
As the cluster progressively upgrades to version 7.2, we can expect the
shard_ids across all nodes to naturally converge and align.
In this PR, when processing the gossip, if sender is a replica and does not
support shard-id, set the shard_id to the shard_id of its master.

When we register notification or server event in RedisModule_OnLoad, but
RedisModule_OnLoad eventually fails, triggering notification or server

If the loading fails on a later stage of moduleLoad, we do call

RedisModule_OnLoad
call, we only un-register several specific things and these were
missing:
- moduleUnsubscribeNotifications
- moduleUnregisterFilters
- moduleUnsubscribeAllServerEvents
