This special command is used by the slave to inform the master the amount of replication stream it currently consumed. it does not return anything so that we not need to consume additional bandwidth needed by the master to reply something. The master can do a number of things knowing the amount of stream processed, such as understanding the "lag" in bytes of the slave, verify if a given command was already processed by the slave, and so forth.

When master send commands, there is no need for the slave to reply. Redis used to queue the reply in the output buffer and discard the reply later, this is a waste of work and it is not clear why it was this way (I sincerely don't remember). This commit changes it in order to don't queue the reply at all. All tests passing.

We don't write the output buffer to the client socket for slaves only if the slave is not online.

Should be "continue" and was "return". This fixes issue #1110

Also the logfile option was modified to always have an explicit value and to log to stdout when an empty string is used as log file. Previously there was special handling of the string "stdout" that set the logfile to NULL, this always required some special handling.

This reverts commit 2c75f2cf. After further analysis, it is very unlikely that we'll raise the string size limit to > 512MB, and at the same time such big strings will be used in 32 bit systems. Better to revert to size_t so that 32 bit processors will not be forced to use a 64 bit counter in normal operations, that is currently completely useless.

When the PONG delay is half the cluster node timeout, the link gets disconnected (and later automatically reconnected) in order to ensure that it's not just a dead connection issue. However this operation is only performed if the link is old enough, in order to avoid to disconnect the same link again and again (and among the other problems, never receive the PONG because of that). Note: when the link is reconnected, the 'ping_sent' field is not updated even if a new ping is sent using the new connection, so we can still reliably detect a node ping timeout.

Also clusterBroadcastPing() was renamed into clusterBroadcastPong() that's what the function is actually doing.

This is just to make the code exactly like the above instance used for requirepass. No actual change nor the original code violated the Redis coding style.

There was a race condition in the AOF rewrite code that, with bad enough timing, could cause a volatile key just about to expire to be turned into a non-volatile key. The bug was never reported to cause actualy issues, but was found analytically by an user in the Redis mailing list: https://groups.google.com/forum/?fromgroups=#!topic/redis-db/Kvh2FAGK4Uk This commit fixes issue #1079.

Tilt mode was too aggressive (not processing INFO output), this resulted in a few problems: 1) Redirections were not followed when in tilt mode. This opened a window to misinform clients about the current master when a Sentinel was in tilt mode and a fail over happened during the time it was not able to update the state. 2) It was possible for a Sentinel exiting tilt mode to detect a false fail over start, if a slave rebooted with a wrong configuration about at the same time. This used to happen since in tilt mode we lose the information that the runid changed (reboot). Now instead the Sentinel in tilt mode will still remove the instance from the list of slaves if it changes state AND runid at the same time. Both are edge conditions but the changes should overall improve the reliability of Sentinel.
