dc10245f07 SPOP with count: fix replication for code path #3. 2015-02-11 10:11:28 +01:00

83a8739e42 SPOP: reimplemented for speed and better distribution. 
The old version of SPOP with "count" argument used an API call of dict.c
which was actually designed for a different goal, and was not capable of
good distribution. We follow a different three-cases approach optimized
for different ratiion between sets and requested number of elements.

The implementation is simpler and allowed the removal of a large amount
of code.

54c27e079a Change alsoPropagate() behavior to make it more usable. 
Now the API automatically creates its argv copy and increment ref count
of passed objects.

359113cc22 SPOP with count: initial fixes to the implementation. 
Severan problems are addressed but still a few missing.
Since replication of this command was more complex than others since it
needs to replicate multiple SREM commands, an old API able to do this
was reused (it was taken inside the implementation since it was pretty
obvious soon or later that would be useful). The API was improved a bit
so that now a command may opt-out for the standard command replication
when the server.dirty counter is incremented, in order to "manually"
replicate what it wants.

17fa6b087d dict.c: don't try buckets that are empty for sure in dictGetRandomKey(). 
This is very similar to the optimization applied to dictGetRandomKeys,
but applied to the single key variant.

cfe21852e7 redis-cli --latecy-dist reverted to gray scale. 
So far not able to find a color palette within the 256 colors which is
not confusing. However I believe it is a possible task, so will try
better later.

2723412b7b redis-cli --latency-dist now uses a color palette. 
Still not happy with the result but low grays are hard to see in certain
monitors with a non perfect gamma.

7d1e158084 Handle redis-check-rdb as a standalone program. 
This also makes it backward compatible in the usage, but for the command
name. However the old command name was less obvious so it is worth to
break it probably.

With the new setup the program main can perform argument parsing and
everything else useful for an RDB check regardless of the Redis server
itself.

233729fe7f Cluster: some bias towwards FAIL/PFAIL nodes in gossip sections. 
This improves PFAIL -> FAIL switch. Too late at this point in the RC
releases to add proper PFAIL/FAIL separate dictionary to do this in a
less randomized way. Tested in practice with experiments that this
helps. PFAIL -> FAIL average with 20 nodes and node-timeout set to 5
seconds takes 2.5 seconds without this commit, 1 second with this
commit.

3fd43062c8 Cluster: use a number of gossip sections proportional to cluster size. 
Otherwise it is impossible to receive the majority of failure reports in
the node_timeout*2 window in larger clusters.

Still with a 200 nodes cluster, 20 gossip sections are a very reasonable
amount of bytes to send.

A side effect of this change is also fater cluster nodes joins for large
clusters, because the cluster layout makes less time to propagate.
