The new command allows to change master-specific configurations at runtime. All the settable parameters can be retrivied via the SENTINEL MASTER command, so there is no equivalent "GET" command.

The command totally removes a monitored master.

The claim about unlinking the instance from the connected hash tables was the opposite of the reality. Also the current actual behavior is safer in most cases, so it is better to manually unlink when needed.

It allows to add new masters to monitor at runtime.

The new function is used when we want to normalize an IP address without performing a DNS lookup if the string to resolve is not a valid IP. This is useful every time only IPs are valid inputs or when we want to skip DNS resolution that is slow during runtime operations if we are required to block.

With SENTINEL MASTERS it was already possible to list all the configured masters, but not a specific one.

Note: the auth password with the master is voluntarily not exposed.

long was used instead of long long in order to handle a 64 bit resolution millisecond timestamp. This fixes issue #1483.

Fixes issue #1491 on Github.

Masters not understanding REPLCONF ACK will reply with errors to our requests causing a number of possible issues. This commit detects a global replication offest set to -1 at the end of the replication, and marks the client representing the master with the REDIS_PRE_PSYNC flag. Note that this flag was called REDIS_PRE_PSYNC_SLAVE but now it is just REDIS_PRE_PSYNC as it is used for both slaves and masters starting with this commit. This commit fixes issue #1488.

Durign a refactoring I mispelled _port for port. This is one of the reasons I never used _varname myself.

Now the socket is closed if anetNonBlock() fails, and in general the code structure makes it harder to introduce this kind of bugs in the future. Reference: pull request #1059.

There were two problems with the implementation. 1) "save" was not correctly processed when no save point was configured, as reported in issue #1416. 2) The way the code checked if an option existed in the "processed" dictionary was wrong, as we add the element with as a key associated with a NULL value, so dictFetchValue() can't be used to check for existance, but dictFind() must be used, that returns NULL only if the entry does not exist at all.

This was no longer the case with 2.8 becuase of a bug introduced with the IPv6 support. Now it is fixed. This fixes issue #1287 and #1477.

Currently replication offsets could be used into a limited way in order to understand, out of a set of slaves, what is the one with the most updated data. For example this comparison is possible of N slaves were replicating all with the same master. However the replication offset was not transferred from master to slaves (that are later promoted as masters) in any way, so for instance if there were three instances A, B, C, with A master and B and C replication from A, the following could happen: C disconnects from A. B is turned into master. A is switched to master of B. B receives some write. In this context there was no way to compare the offset of A and C, because B would use its own local master replication offset as replication offset to initialize the replication with A. With this commit what happens is that when B is turned into master it inherits the replication offset from A, making A and C comparable. In the above case assuming no inconsistencies are created during the disconnection and failover process, A will show to have a replication offset greater than C. Note that this does not mean offsets are always comparable to understand what is, in a set of instances, since in more complex examples the replica with the higher replication offset could be partitioned away when picking the instance to elect as new master. However this in general improves the ability of a system to try to pick a good replica to promote to master.

CONFIG REWRITE is now wiser and does not touch what it does not understand inside redis.conf.

Those options will be thrown without this patch: include, rename-command, min-slaves-to-write, min-slaves-max-lag, appendfilename.

With this commit options not explicitly rewritten by CONFIG REWRITE are not touched at all. These include new options that may not have support for REWRITE, and other special cases like rename-command and include.

The bug could be easily triggered by: SADD foo a b c 1 2 3 4 5 6 SDIFF foo foo When the key was the same in two sets, an unsafe iterator was used to check existence of elements in the same set we were iterating. Usually this would just result into a wrong output, however with the dict.c API misuse protection we have in place, the result was actually an assertion failed that was triggered by the CI test, while creating random datasets for the "MASTER and SLAVE consistency" test.

When a slave was disconnected from its master the replication offset was reported as -1. Now it is reported as the replication offset of the previous master, so that failover can be performed using this value in order to try to select a slave with more processed data from a set of slaves of the old master.
