The key save delay is too short and on certain systems the child process
is gone before we have a chance to inspect it.

This is a catch-all test to confirm that that rewrite produces a valid
output for all parameters and that this process does not introduce
undesired configuration changes.

THP can also be set to madvise, in which case it shouldn't cause
problems for Redis since redis (or the allocator) doesn't use madvise
to activate it.

There was a bug. Although cluster replicas would allow read commands,
they would not allow a MULTI-EXEC that's composed solely of read commands.
Adds tests for coverage.

(cherry picked from commit b120366d48)
if there are nested tests and nested servers, we need to restore the
previous value of cur_test when a test exist.
example:
```
test{test 1} {
start_server {
test{test 1.1 - master only} {
}
start_server {
test{test 1.2 - with replication} {
}
}
}
}
```
when `test 1.1 - master only exists`, we're still inside `test 1`
(cherry picked from commit 0a1e734193)
1) cur_test: when restart_server, "no such variable" error occurs
./runtest --single integration/rdb
test {client freed during loading}
SET ::cur_test
restart_server
kill_server
test "Check for memory leaks (pid $pid)"
SET ::cur_test
UNSET ::cur_test
UNSET ::cur_test // This global variable has been unset.
2) `ps --ppid` not available on macOS platform, can be replaced with
`pgrep -P pid`.

This test was failing from time to time see discussion at the bottom of #7635
This was probably due to timing, the DEBUG SLEEP executed by redis-cli
didn't sleep for enough time.
This commit changes:
1) use SET-ACTIVE-EXPIRE instead of DEBUG SLEEP
2) reduce many `after` sleeps with retry loops to speed up the test.
3) add many comment explaining the different steps of the test and
it's purpose.
4) config appendonly before populating the volatile keys, so that they'll
be part of the AOF command stream rather than the preamble RDB portion.
other complications: recently kill_instance switched from SIGKILL to
SIGTERM, and this would sometimes fail since there was an AOFRW running
in the background. now we wait for it to end before attempting the kill.

There is an inherent race condition in port allocation for spawned
servers. If a server fails to start because a port is taken, a new port
is allocated. This fixes a problem where the logs are not truncated and
as a result a large number of unmonitored servers are started.

2b998de46 added a file for stderr to keep valgrind log but i forgot to
add a similar thing when valgrind isn't being used.
the result is that `glob */err.txt` fails.
(cherry picked from commit 42ba7a1b75)
- redirect valgrind reports to a dedicated file rather than console
- try to avoid killing instances with SIGKILL so that we get the memory
leak report (killing with SIGTERM before resorting to SIGKILL)
- search for valgrind reports when done, print them and fail the tests
- add --dont-clean option to keep the logs on exit
- fix exit error code when crash is found (would have exited with 0)
changes that affect the normal redis test suite:
- refactor check_valgrind_errors into two functions one to search and
one to report
- move the search half into util.tcl to serve the cluster tests too
- ignore "address range perms" valgrind warnings which seem non relevant.
(cherry picked from commit 2b998de460)
in some cases a command that returns an error possibly due to a timing
issue causes the tcl code to crash and thus prevents the rest of the
tests from running. this adds an option to make the test proceed despite
the crash.
maybe it should be the default mode some day.
(cherry picked from commit fe5da2e60d)
- skip full units
- skip a single test (not just a list of tests)
- when skipping tag, skip spinning up servers, not just the tests
- skip tags when running against an external server too
- allow using multiple tags (split them)

Fix issues with writeConn() which resulted with corruption of the stream by leaving an extra byte in the buffer. The trigger for this is partial writes or write errors which were not experienced on Linux but reported on macOS.

When redis isn't configured to have a log file, having these prints

When runtest-cluster, at first, we need to create a cluster use spawn_instance,
a port which is not used is choosen, however sometimes we can't run server on
the port. possibley due to a race with another process taking it first.
such as redis/redis/runs/896537490. It may be due to the machine problem or
In order to reduce the probability of failure when start redis in
runtest-cluster, we attemp to use another port when find server do not start up.

This fixes the issue described in CVE-2014-5461. At this time we cannot
confirm that the original issue has a real impact on Redis, but it is
included as an extra safety measure.

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.

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.

65a3307bc (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.

(cherry picked from commit 9fcd9e191e)
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 b7289e912c)
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.

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.
