Sentinels are now desynchronized in a better way changing the time handler frequency between 10 and 20 HZ. This way on average a desynchronization of 25 milliesconds is produced that should be larger enough compared to network latency, avoiding most split-brain condition during the vote. Now that the clocks are desynchronized, to have larger random delays when performing operations can be easily achieved in the following way. Take as example the function that starts the failover, that is called with a frequency between 10 and 20 HZ and will start the failover every time there are the conditions. By just adding as an additional condition something like rand()%4 == 0, we can amplify the desynchronization between Sentinel instances easily. See issue #1419.

The result of this one-char bug was pretty serious, if the new master had the same port of the previous master, but just a different IP address, non-leader Sentinels would not be able to recognize the configuration change. This commit fixes issue #1394. Many thanks to @shanemadden that reported the bug and helped investigating it.

This commit introduces a funciton called when Sentinel is ready for normal operations to avoid putting Sentinel specific stuff in redis.c.

Does not fix any bug as the test is performed by the caller, but better to have the check.

At the end of the file, CONFIG REWRITE adds a comment line that: # Generated by CONFIG REWRITE Followed by the additional config options required. However this was added again and again at every rewrite in praticular conditions (when a given set of options change in a given time during the time). Now if it was alrady encountered, it is not added a second time. This is especially important for Sentinel that rewrites the config at every state change.

Some are just to know if the master is down, and in this case the runid in the request is set to "*", others are actually in order to seek for a vote and get elected. In the latter case the runid is set to the runid of the instance seeking for the vote.

Also the sentinel configuration rewriting was modified in order to account for failover in progress, where we need to provide the promoted slave address as master address, and the old master address as one of the slaves address.
