Sun He 2385630d0d dict.c/dictRehash: check again to update 2015-02-11 10:52:26 +01:00
antirez 4f427bc298 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.

Related to issue #2306.

antirez 1bcf67a75f dict.c: dictGetRandomKeys() optimization for big->small table case.

antirez 88cd9ebc09 dict.c: dictGetRandomKeys() visit pattern optimization. 
We use the invariant that the original table ht[0] is never populated up
to the index before the current rehashing index.

antirez 5e3dcc522b Faster memory efficiency test. 
This test on Linux was extremely slow, since in Tcl we can't enable
easily tcp-nodelay, so the busy loop used to take *a lot* with bigger
writes. Fixed using pipelining.

antirez ca23b2a6b7 redis-cli: interactive reconnection for latency modes. 
--stat mode already used to reconnect automatically if the server is no
longer available. This is useful since this is an interactive mode used
for debugging, however the same applies to --latency and --latency-dist
modes, so now both use the reconnecting command execution as well.

The reconnection code was modified to use basic VT100 escape sequences
in order to play better with different kinds of output on the screen
when the reconnection happens, and to hide the reconnection attempt
output when finally the reconnection happens.

antirez 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.
 2015-02-08 17:39:42 +01:00
antirez 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.

antirez fad758b322 Check RDB automatically in a few more cases. 2015-02-03 10:33:05 +01:00
antirez 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.

antirez 45102a6f63 Norrow backtrace and setproctitle() to Linux+glibc. 
Backtrace is a glibc extension, while setproctitle() implementation
depends on the memory layout and is partially libc dependent.

antirez 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.

antirez 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.
