* 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.
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).
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 )
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.
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).

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

This commit provides an optimization, in terms of time, for all GEORADIUS*
and GEOSEARCH* searches which utilize the default, sorted, COUNT clause.
This is commonly used for nearest-neighbor (top-K points closest to a given lat/lon)
searches. While the previous implementation appends all matching points to the
geoPoint array and performs pruning after-the-fact via a full sort and [0, count)-based
for-loop, this PR sorts only the required number of elements.
This optimization provides a 5-20% improvement in runtime depending on the
density of points of interest (POI) as well as the radius searched.
No performance degradation has been observed.
addReplyLongLongWithPrefix, has a check against negative length, and the code
flow removed in this commit bypasses the check.
addReplyAggregateLen has an assertion for negative length, but addReplyBulkLen
does not, so this commit fixes theoretical case of access violation (probably
unreachable though)
