Change REDIS_CLUSTER_IPLEN to INET6_ADDRSTRLEN so that the clusterNode ip character buffer is big enough to hold an IPv6 address.
-
Geoff Garside authored
Add REDIS_CLUSTER_IPLEN macro to define the size of the clusterNode ip character array. Additionally use this macro in inet_ntop(3) calls where the size of the array was being defined manually. The REDIS_CLUSTER_IPLEN is defined as INET_ADDRSTRLEN which defines the correct size of a buffer to store an IPv4 address in. The INET_ADDRSTRLEN macro itself is defined in the <netinet/in.h> header file and should be portable across the majority of systems.

This commit uses the Replication Script Cache in order to avoid translating EVALSHA into EVAL whenever possible for both the AOF and slaves.
-
antirez authored
This code is only responsible to take an LRU-evicted fixed length cache of SHA1 that we are sure all the slaves received. In this commit only the implementation is provided, but the Redis core does not use it to actually send EVALSHA to slaves when possible.

The old REDIS_CMD_FORCE_REPLICATION flag was removed from the implementation of Redis, now there is a new API to force specific executions of a command to be propagated to AOF / Replication link: void forceCommandPropagation(int flags); The new API is also compatible with Lua scripting, so a script that will execute commands that are forced to be propagated, will also be propagated itself accordingly even if no change to data is operated. As a side effect, this new design fixes the issue with scripts not able to propagate PUBLISH to slaves (issue #873).

Currently it implements three subcommands: PUBSUB CHANNELS [<pattern>] List channels with non-zero subscribers. PUBSUB NUMSUB [channel_1 ...] List number of subscribers for channels. PUBSUB NUMPAT Return number of subscribed patterns.

This feature allows the user to specify the minimum number of connected replicas having a lag less or equal than the specified amount of seconds for writes to be accepted.

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.

NetBSD-current's libc has a function named popcount. hiding these extensions using feature macros is not possible because redis uses other extensions covered by the same feature macro. eg. inet_aton

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.

We used to copy this value into the server.cluster structure, however this was not necessary. The reason why we don't directly use server.cluster->node_timeout is that things that can be configured via redis.conf need to be directly available in the server structure as server.cluster is allocated later only if needed in order to reduce the memory footprint of non-cluster instances.

When a BGSAVE fails, Redis used to flood itself trying to BGSAVE at every next cron call, that is either 10 or 100 times per second depending on configuration and server version. This commit does not allow a new automatic BGSAVE attempt to be performed before a few seconds delay (currently 5). This avoids both the auto-flood problem and filling the disk with logs at a serious rate. The five seconds limit, considering a log entry of 200 bytes, will use less than 4 MB of disk space per day that is reasonable, the sysadmin should notice before of catastrofic events especially since by default Redis will stop serving write queries after the first failed BGSAVE. This fixes issue #849

A slave node set this flag for itself when, after receiving authorization from the majority of nodes, it turns itself into a master. At the same time now this flag is tested by nodes receiving a PING message before reconfiguring after a failover event. This makes the system more robust: even if currently there is no way to manually turn a slave into a master it is possible that we'll have such a feature in the future, or that simply because of misconfiguration a node joins the cluster as master while others believe it's a slave. This alone is now no longer enough to trigger reconfiguration as other nodes will check for the PROMOTED flag. The PROMOTED flag is cleared every time the node is turned back into a replica of some other node.

Sender flags were not propagated for the sender, but only for nodes in the gossip section. This is odd and in the next commits we'll need to get updated flags for the sender node, so this commit adds a new field in the cluster messages header. The message header is the same size as we reused some free space that was marked as 'unused' because of alignment concerns.

Redis Cluster can cope with a minority of nodes not informed about the failure of a master in time for some reason (netsplit or node not functioning properly, blocked, ...) however to wait a few seconds before to start the failover will make most "normal" failovers simpler as the FAIL message will propagate before the slave election happens.

That's trivial as we just need to increment the count of masters that received with an ACK.
