It seems like non-Linux sockets may be less greedy, resulting with more
transient client output buffers.
Haven't proven this but empirically when stressing this test on
non-Linux tends to exhibit increased mem_clients_normal values.
* The `redis-cli --scan` output should honor output mode (set explicitly or implicitly), and quote key names when not in raw mode.
* Technically this is a breaking change, but it should be very minor since raw mode is by default on for non-tty output.
* It should only affect TTY output (human users) or non-tty output if `--no-raw` is specified.
* Added `--quoted-input` option to treat all arguments as potentially quoted strings.
* Added `--quoted-pattern` option to accept a potentially quoted pattern.
Unquoting is applied to potentially quoted input only if single or double quotes are used.

When sanitizing the stream listpack, we need to count the deleted records too.
otherwise the last line that checks the next pointer fails.
Add test to cover that state in the stream tests.
Add ability to modify port, tls-port and bind configurations by CONFIG SET command.
To simplify the code and make it cleaner, a new structure
added, socketFds, which contains the file descriptors array and its counter,
and used for TCP, TLS and Cluster sockets file descriptors.
Because when the RM_Call is invoked. It will create a faker client.
The point is client connection is NULL, so server will crash in connGetInfo

A single client pointer is added in the server struct. This is
initialized by the first RM_Call() and reused for every subsequent
RM_Call() except if it's already in use, which means that it's not
used for (recursive) module calls to modules. For these, a new
"fake" client is created each time.
Other changes:
* Avoid allocating a dict iterator in pubsubUnsubscribeAllChannels
when not needed
* Remove linux/version.h dependency.
This introduces unnecessary dependencies, and generally not a good idea
as the platform we build on may be different than the platform we run
on.
To determine if sync_file_range exists we can simply rely on header file
hints.
* Fix setproctitle() on libmusl.
The previous ifdef checks were a bit too strict for no apparent
reason.
* Fix tests failure on Linux with no backtrace.
* Add alpine daily CI job.
This validation was only done for sub-commands and not for commands.
These would have been valid (not produce any error)
ACL SETUSER bob +@all +client
ACL SETUSER bob +client +client
so no reason for this one to fail:
ACL SETUSER bob +client +client|id
One example why this is needed is that pfdebug wasn't part of the @hyperloglog
group and now it is. so something like:
acl setuser user1 +@hyperloglog +pfdebug|test
would have succeeded in early 6.0.x, and fail in 6.2 RC3

When redis responds with tracking-redir-broken push message (RESP3),
it was responding with a broken protocol: an array of 3 elements, but only
pushes 2 elements.
Some bugs in the test make this pass. Read the push reply
will consume an extra reply, because the reply length is 3, but there
are only two elements, so the next reply will be treated as third
element. So the test is corrected too.
Other changes:
* checkPrefixCollisionsOrReply success should return 1 instead of -1,
this bug didn't have any implications.
* improve client tracking tests to validate more of the response it reads.
Respond with error if expire time overflows from positive to negative of vice versa.
* `SETEX`, `SET EX`, `GETEX` etc would have already error on negative value,
but now they would also error on overflows (i.e. when the input was positive but
after the manipulation it becomes negative, which would have passed before)
* `EXPIRE` and `EXPIREAT` was ok taking negative values (would implicitly delete
the key), we keep that, but we do error if the user provided a value that changes
sign when manipulated (except the case of changing sign when `basetime` is added)

* Adding current_save_keys_total and current_save_keys_processed info fields.
Present in replication, BGSAVE and AOFRW.
* Changing RM_SendChildCOWInfo() to RM_SendChildHeartbeat(double progress)
* Adding new info field current_fork_perc. Present in Replication, BGSAVE, AOFRW,
and module forks.
There are two tests in other.tcl that were dependant of the sha1 package
import which meant that they didn't usually run.
The reason it was like that was that prior to the creation of DEBUG
DIGEST, the test suite used to have an equivalent function, but that's
no longer the case and this dependency isn't needed.
The other change is to revert config changes done by the test before the
test suite continues. can be useful if using `--host` to run multiple
units against the same server
The added flag affects the return value of RM_HashSet() to include
the number of inserted fields, in addition to updated and deleted
fields.
errno is set on errors, tests are added and documentation updated.
* Don't run test script on non-Linux.
* Verify that reported fds do indeed exist also in parent, to avoid
false negatives on some systems (namely CentOS).

- removes time sensitive checks from block on background tests during leak checks.
- fix uninitialized variable on RedisModuleBlockedClient() when calling
RM_BlockedClientMeasureTimeEnd() without RM_BlockedClientMeasureTimeStart()
1. Rename 18-cluster-nodes-slots.tcl to 19-cluster-nodes-slots.tcl.
it was conflicting with another test prefixed by 18
2. Release memory on exit in redis-cli.c.
3. Fix freeConvertedSds indentation.
* For consistency, use tclsh for the script as well
* Ignore leaked fds that originate from grandparent process, since we
only care about fds redis-sentinel itself is responsible for
* Check every test iteration to catch problems early
* Some cleanups, e.g. parameterization of file name, etc.
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.
Changes to HRANDFIELD and ZRANDMEMBER:
* Fix risk of OOM panic when client query a very big negative count (avoid allocating huge temporary buffer).
* Fix uneven random distribution in HRANDFIELD with negative count (wasn't using dictGetFairRandomKey).
* Add tests to check an even random distribution (HRANDFIELD, SRANDMEMBER, ZRANDMEMBER).

Fix errors of GEOSEARCH bybox search due to:
1. projection of the box to a trapezoid (when the meter box is converted to long / lat it's no longer a box).
2. width and height mismatch
Changes:
- New GEOSEARCH point in rectangle algorithm
- Fix GEOSEARCH bybox width and height mismatch bug
- Add GEOSEARCH bybox testing to the existing "GEOADD + GEORANGE randomized test"
- Add new fuzzy test to stress test the bybox corners and edges
- Add some tests for edge cases of the bybox algorithm

* 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.
* 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.
This commit fixes sentinel announces hostnames test error in certain linux environment
Before this commit, we only check localhost is resolved into 127.0.0.1, however in ubuntu
or some other linux environments "localhost" will be resolved into ::1 ipv6 address first if
the network stack is capable.
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
