Avoids memmove and reallocs when replacing a ziplist element of the
same encoded size as the new value.
Affects HSET, HINRBY, HINCRBYFLOAT (via hashTypeSet) and LSET (via
quicklistReplaceAtIndex).
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.
Fix the pointers to the slot hash tags in the case of prefixed commands usage
i.e. AUTH / SELECT
It adjusts the pointers to the slot hash tags in the case of prefixed commands
usage as soon as we get the 1st reply (same like we already did for the random
strings within the command )
* 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).

We need to store replicas referenced by their announced address (IP or
address). Before that, if hostnames were used and the IP address
changed, duplicate entries would have been created.
- 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.
When (remaining == (total_size - index)), element will definitely be random to.
But when rand() == RAND_MAX, the element will miss, this will trigger assert
in serverAssert(ziplistRandomPairsUnique(zsetobj->ptr, count, keys, vals) == count).
It is inefficient to repeatedly pick a single random element from a
ziplist.
For CASE4, which is when the user requested a low number of unique
random picks from the collectoin, we used thta pattern.
Now we use a different algorithm that picks unique elements from a
ziplist, and guarentee no duplicate but doesn't provide random order
(which is only needed in the non-unique random picks case)
Unrelated changes:
* change ziplist count and indexes variables to unsigned
* solve compilation warnings about uninitialized vars in gcc 10.2

Disable certificate validation, making it possible to connect to servers
without configuring full trust chain.
The use of this option is insecure and makes the connection vulnerable
to man in the middle attacks.
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).
