antirez e5b5763f56 REPLACE option for RESTORE. 
The REPLACE option deletes an existing key with the same name (if any)
and materializes the new one. The default behavior without RESTORE is to
return an error if a key already exists.

antirez 6fdc635447 Better Out of Memory handling. 
The previous implementation of zmalloc.c was not able to handle out of
memory in an application-specific way. It just logged an error on
standard error, and aborted.

The result was that in the case of an actual out of memory in Redis
where malloc returned NULL (In Linux this actually happens under
specific overcommit policy settings and/or with no or little swap
configured) the error was not properly logged in the Redis log.

This commit fixes this problem, fixing issue #509.
Now the out of memory is properly reported in the Redis log and a stack
trace is generated.

The approach used is to provide a configurable out of memory handler
to zmalloc (otherwise the default one logging the event on the
standard output is used).

antirez d38ef52085 Redis Cluster: process node to node CLUSTERMSG_TYPE_PUBLISH messages and send it to the local clients. 2011-10-07 16:34:16 +02:00
antirez c563ce463b propagate PUBLISH messages using the redis cluster nodes bus. Still need to process the incoming packets of that type. Work in progress. 2011-10-07 15:37:34 +02:00
antirez 9465d83efd A node can populate a slot if a message from a trusted slot is received claiming ownership of this slot, that is currently empty or served by a node in FAIL state. However this feature was broken since calling clusterAddSlot() was not enough as the slot bit is already set in the node that pong us. We need to directly alter the table. This commit fixes the issue. 2011-10-05 17:40:02 +02:00
