Further details from @antirez: It was reported by @StopForumSpam on Twitter that the Redis replication link was strangely using multiple TCP packets for multiple commands. This wastes a lot of bandwidth and is due to the TCP_NODELAY option we enable on the socket after accepting a new connection. However the master -> slave channel is a one-way channel since Redis replication is asynchronous, so there is no point in trying to reduce the latency, we should aim to reduce the bandwidth. For this reason this commit introduces the ability to disable the nagle algorithm on the socket after a successful SYNC. This feature is off by default because the delay can be up to 40 milliseconds with normally configured Linux kernels.

There was a bug in the previous version of this library that caused a crash under the circumstances described in issue #901. The newer version of the library appears to be fixed (I tested it manually with valgrind and everything seems fine now). For more information about this library please visit this web site: http://www.inf.puc-rio.br/~roberto/struct/

UNSUBSCRIBE and PUNSUBSCRIBE commands are designed to mass-unsubscribe the client respectively all the channels and patters if called without arguments. However when these functions are called without arguments, but there are no channels or patters we are subscribed to, the old behavior was to don't reply at all. This behavior is broken, as every command should always reply. Also it is possible that we are no longer subscribed to a channels but we are subscribed to patters or the other way around, and the client should be notified with the correct number of subscriptions. Also it is not pretty that sometimes we did not receive a reply at all in a redis-cli session from these commands, blocking redis-cli trying to read the reply. This fixes issue #714.

I don't know how to test for Open Solaris that has support for backtrace() so for now removing the #ifdef that breaks compilation under other Solaris flavors.

This commit fixes issue #875 that was caused by the following events: 1) There is an active child doing BGSAVE. 2) flushall is called (or any other condition that makes Redis killing the saving child process). 3) An error is sensed by Redis as the child exited with an error (killed by a singal), that stops accepting write commands until a BGSAVE happens to be executed with success. Whitelisting SIGUSR1 and making sure Redis always uses this signal in order to kill its own children fixes the issue.

When a SIGTERM is received Redis schedules a shutdown. However if it fails to perform the shutdown it must be clear the shutdown_asap flag otehrwise it will try again and again possibly making the server unusable.

The Redis Slow Log always used to log the slow commands executed inside a MULTI/EXEC block. However also EXEC was logged at the end, which is perfectly useless. Now EXEC is no longer logged and a test was added to test this behavior. This fixes issue #759.

Redis pings slaves in "pre-synchronization stage" with newlines. (See https://github.com/antirez/redis/blob/2.6.9/src/replication.c#L814) However, redis-cli does not expect this - it sees the newline as the end of the bulk length line, and ends up returning 0 as bulk the length. This manifests as the following when running redis-cli: $ ./src/redis-cli --rdb some_file SYNC sent to master, writing 0 bytes to 'some_file' Transfer finished with success. With this commit, we just ignore leading newlines while reading the bulk length line. To reproduce the problem, load enough data into Redis so that the preparation of the RDB snapshot takes long enough for a ping to occur while redis-cli is waiting for the data.

Sometimes it is much simpler to debug complex Redis installations if it is possible to assign clients a name that is displayed in the CLIENT LIST output. This is the case, for example, for "leaked" connections. The ability to provide a name to the client makes it quite trivial to understand what is the part of the code implementing the client not releasing the resources appropriately. Behavior: CLIENT SETNAME: set a name for the client, or remove the current name if an empty name is set. CLIENT GETNAME: get the current name, or a nil. CLIENT LIST: now displays the client name if any. Thanks to Mark Gravell for pushing this idea forward.

Issue #828 shows how Redis was not correctly undoing a non-blocking connection attempt with the previous master when the master was set to a new address using the SLAVEOF command. This was also a result of lack of refactoring, so now there is a function to cancel the non blocking handshake with the master. The new function is now used when SLAVEOF NO ONE is called or when SLAVEOF is used to set the master to a different address.

1) The event handler was no restored after a timeout condition if the command was eventually executed with success. 2) The command was not converted to EVAL in case of errors in the middle of the execution. 3) Terrible duplication of code without any apparent reason.

The problem does not exist in the Redis server implementation of mstime() but is only limited to redis-cli and redis-benchmark. Thix fixes issue #839.

Config.h performs endianess detection including OS-specific headers to define the endianess macros, or when this is not possible, checking the processor type via ifdefs. Sometimes when the OS-specific macro is included, only __BYTE_ORDER is defined, while BYTE_ORDER remains undefined. There is code at the end of config.h endianess detection in order to define the macros without the underscore, but it was not working correctly. This commit fixes endianess detection fixing Redis on Linux / PPC64 and possibly other systems.
