 2013-02-15 11:57:53 +01:00
antirez 20f52b5b78 Top comment for getNodeByQuery() improved. 2013-02-15 11:50:54 +01:00
antirez 6b641f3aeb redis-cli: update prompt on cluster redirection. 2013-02-14 18:49:08 +01:00
antirez e0e15bd06d Cluster: with 16384 slots we need bigger buffers. 2013-02-14 15:36:33 +01:00
antirez 1a32d99b28 Cluster: move cluster config file out of config state. 
This makes us able to avoid allocating the cluster state structure if
cluster is not enabled, but still we can handle the configuration
directive that sets the cluster config filename.

antirez 0ed6daa48b PSYNC: don't use the client buffer to send +CONTINUE and +FULLRESYNC. 
When we are preparing an handshake with the slave we can't touch the
connection buffer as it'll be used to accumulate differences between
the sent RDB file and what arrives next from clients.

So in short we can't use addReply() family functions.

However we just use write(2) because we know that the socket buffer is
empty, since a prerequisite for SYNC to work is that the static buffer
and the output list are empty, and in general it is not expected that a
client SYNCs after doing some heavy I/O with the master.

However a short write connection is explicitly handled to avoid
fragility (we simply close the connection and the slave will retry).

antirez d2a0348a49 SYNC not allowed with pending data on the static output buffer. 2013-02-12 12:52:21 +01:00

antirez 41d64a7516 After SLAVEOF <newslave> don't allow chained slaves to PSYNC. 2013-02-12 12:52:21 +01:00
antirez 078882025e PSYNC: work in progress, preview #2, rebased to unstable. 2013-02-12 12:52:21 +01:00
antirez e34a35a511 Use the new unified protocol to send SELECT to slaves. 
SELECT was still transmitted to slaves using the inline protocol, that
is conceived mostly for humans to type into telnet sessions, and is
notably not understood by redis-cli --slave.

Now the new protocol is used instead.
 2013-02-12 12:50:28 +01:00
antirez 4b83ad4e1f Use replicationFeedSlaves() to send PING to slaves. 
A Redis master sends PING commands to slaves from time to time: doing
this ensures that even if absence of writes, the master->slave channel
remains active and the slave can feel the master presence, instead of
closing the connection for timeout.

This commit changes the way PINGs are sent to slaves in order to use the
standard interface used to replicate all the other commands, that is,
the function replicationFeedSlaves().

With this change the stream of commands sent to every slave is exactly
the same regardless of their exact state (Transferring RDB for first
synchronization or slave already online). With the previous
implementation the PING was only sent to online slaves, with the result
that the output stream from master to slaves was not identical for all
the slaves: this is a problem if we want to implement partial resyncs in
the future using a global replication stream offset.

TL;DR: this commit should not change the behaviour in practical terms,
but is just something in preparation for partial resynchronization
support.
