redis-cli does no longer try to auto detect if it is used inside a pipe. To read last argument from stdandard input there is to use the -x option. This will make it playing better inside cron scripts and in general when stdin is hacked.

Fix re-enabled again, I forgot to check if VM was enabled before calling handleClientsBlockedOnSwappedKey()

Fixed a race condition in VM happening when a key was deleted while there was a client waiting for this key to be resumed from swap to memory. The client would hang forever.

When creating the readable event results in an error (this happens when
the server hits OS limits), the client was not added to the list of
clients when freeClient was called. This results in an assertion error.
It is better to check this condition first and free the client
immediately when this condition occurs. Port of 00a90feb.

BLPOP inside MULTI/EXEC block no longer crashes, instead if the list is empty the behavior is like if the timeout is reached. This fixes Issue 285

It is now possible to use authentication and DB selection options at the same time in redis-cli (Issue 298)

Fix for a race in BGSAVE that may result in some data not being saved as soon as possible (when the configured saving triggers should fire). Also known as Issue 313, more details there in the google code issue.

Fixed segfault in freeMemoryIfNeeded due to the fact that keys are now sds strings and not objects in the main hash table, thanks to Anthony Lauzon for spotting the bug and providing a patch.
