This gives us a 24 bytes size class which is dict.c dictEntry size, thus improving the memory efficiency of Redis significantly. Moreover other non 16 bytes aligned tiny classes are added that further reduce the fragmentation of the allocator. Technically speaking LG_QUANTUM should be 4 on i386 / AMD64 because of SSE types and other 16 bytes types, however we don't use those, and our jemalloc only targets Redis. New versions of Jemalloc will have an explicit configure switch in order to specify the quantum value for a platform without requiring any change to the Jemalloc source code: we'll switch to this system when available. This change was originally proposed by Oran Agra (@oranagra) as a change to the Jemalloc script to generate the size classes define. We ended doing it differently by changing LG_QUANTUM since it is apparently the supported Jemalloc method to obtain a 24 bytes size class, moreover it also provides us other potentially useful size classes. Related to issue #2510.

When empty strings are created, or when sdsMakeRoomFor() is called, we are likely into an appending pattern. Use at least type 8 SDS strings since TYPE 5 does not remember the free allocation size and requires to call sdsMakeRoomFor() at every new piece appended.

The previos attempt to process each client at least once every ten seconds was not a good idea, because: 1. Usually because of the past min iterations set to 50, you get much better processing period most of the times. 2. However when there are many clients and a normal setting for server.hz, the edge case is triggered, and waiting 10 seconds for a BLPOP that asked for 1 second is not ok. 3. Moreover, because of the high min-itereations limit of 50, when HZ was set to an high value, the actual behavior was to process a lot of clients per second. Also the function checking for timeouts called gettimeofday() at each iteration which can be costly. The new implementation will try to process each client once per second, gets the current time as argument, and does not attempt to process more than 5 clients per iteration if not needed. So now: 1. The CPU usage of an idle Redis process is the same or better. 2. The CPU usage of a busy Redis process is the same or better. 3. However a non trivial amount of work may be performed per iteration when there are many many clients. In this particular case the user may want to raise the "HZ" value if needed. Btw with 4000 clients it was still not possible to noticy any actual latency created by processing 400 clients per second, since the work performed for each client is pretty small.

This is an attempt to use the refcount feature of the sds.c fork provided in the Pull Request #2509. A new type, SDS_TYPE_5 is introduced having a one byte header with just the string length, without information about the available additional length at the end of the string (this means that sdsMakeRoomFor() will be required each time we want to append something, since the string will always report to have 0 bytes available). More work needed in order to avoid common SDS functions will pay the cost of this type. For example both sdscatprintf() and sdscatfmt() should try to upgrade to SDS_TYPE_8 ASAP when appending chars.

Same as redis-cli, now redis-benchmark requires to use hiredis sds copy since it is different compared to the memory optimized fork of Redis sds.

The command reports information about the hash table internal state representing the specified database ID. This can be used in order to investigate rehashings, memory usage issues and for other debugging purposes.

The new return value is the number of keys existing, among the ones specified in the command line, counting the same key multiple times if given multiple times (and if it exists). See PR #2667.

GEOHASH, GEOPOS and GEODIST where declared as commands not accepting keys, so the Redis Cluster redirection did not worked. Close #2671.

Rationale: 1. The commands look like internals exposed without a real strong use case. 2. Whatever there is an use case, the client would implement the commands client side instead of paying RTT just to use a simple to reimplement library. 3. They add complexity to an otherwise quite straightforward API. So for now KILLED ;-)

Instead of successive divisions in iteration the new code uses bitwise magic to interleave / deinterleave two 32bit values into a 64bit one. All tests still passing and is measurably faster, so worth it.

I'm not a strong believer in multiple syntax for the same stuff, so now units can be specified only as m, km, ft, mi.

Stack traces produced by Redis on crash are the most useful tool we have to fix non easily reproducible crashes, or even easily reproducible ones where the user just posts a bug report and does not collaborate furhter. By declaring functions "static" they no longer show up in the stack trace.

If GEOENCODE must be our door to enter the Geocoding implementation details and do fancy things client side, than return the scores as well so that we can query the sorted sets directly if we wish to do the same search multiple times, or want to compute the boxes in the client side to refine our search needs.
