After the transcation starts with a MULIT, the previous behavior was to return an error on problems such as maxmemory limit reached. But still to execute the transaction with the subset of queued commands on EXEC. While it is true that the client was able to check for errors distinguish QUEUED by an error reply, MULTI/EXEC in most client implementations uses pipelining for speed, so all the commands and EXEC are sent without caring about replies. With this change: 1) EXEC fails if at least one command was not queued because of an error. The EXECABORT error is used. 2) A generic error is always reported on EXEC. 3) The client DISCARDs the MULTI state after a failed EXEC, otherwise pipelining multiple transactions would be basically impossible: After a failed EXEC the next transaction would be simply queued as the tail of the previous transaction.

Finally Redis is able to report the amount of memory used by copy-on-write while saving an RDB or writing an AOF file in background. Note that this information is currently only logged (at NOTICE level) and not shown in INFO because this is less trivial (but surely doable with some minor form of interprocess communication). The reason we can't capture this information on the parent before we call wait3() is that the Linux kernel will release the child memory ASAP, and only retain the minimal state for the process that is useful to report the child termination to the parent. The COW size is obtained by summing all the Private_Dirty fields found in the "smap" file inside the proc filesystem for the process. All this is Linux specific and is not available on other systems.

For non Linux systmes it just returns 0. This function is useful to estimate copy-on-write because of childs saving stuff on disk.

When a timeout <= 0 is provided we set a default timeout of 1 second. It was set to 1 millisecond for an error resulting from a recent change.

While it is documented that the MIGRATE timeout is in milliseconds, it was in seconds instead. This commit fixes the problem.

After the wait3() syscall we used to do something like that: if (pid == server.rdb_child_pid) { backgroundSaveDoneHandler(exitcode,bysignal); } else { .... } So the AOF rewrite was handled in the else branch without actually checking if the pid really matches. This commit makes the check explicit and logs at WARNING level if the pid returned by wait3() does not match neither the RDB or AOF rewrite child.

fix typo in comments (redis.c, networking.c)

This also fixes issue #745.

It failed because of the way jemalloc was compiled (without passing the right flags to make, but just to configure). Now the same set of flags are also passed to the make command, fixing the issue. This fixes issue #744

Because of the short circuit behavior of && inverting the two sides of the if expression avoids an hash table lookup if the non-EX variant of SET is called. Thanks to Weibin Yao (@yaoweibin on github) for spotting this.

This was an important information missing from the INFO output in the replication section. It obviously reflects if the slave is read only or not.

(Commit message from @antirez as it was missign in the original commits, also the patch was modified a bit to still work with 2.4 dumps and to avoid if expressions that are always true due to checked types range) This commit changes redis-check-dump to account for new encodings and for the new MSTIME expire format. It also refactors the test for valid type into a function. The code is still compatible with Redis 2.4 generated dumps. This fixes issue #709.

In some system, notably osx, the 3.5 GB limit was too far and not able to prevent a crash for out of memory. The 3 GB limit works better and it is still a lot of memory within a 4 GB theorical limit so it's not going to bore anyone :-) This fixes issue #711

When calling SCRIPT KILL currently you can get two errors: * No script in timeout (busy) state. * The script already performed a write. It is useful to be able to distinguish the two errors, but right now both start with "ERR" prefix, so string matching (that is fragile) must be used. This commit introduces two different prefixes. -NOTBUSY and -UNKILLABLE respectively to reply with an error when no script is busy at the moment, and when the script already executed a write operation and can not be killed.

The code of current implementation: if (c->pending == 0) clientDone(c); In clientDone function, the c's memory has been freed, then the loop will continue: while(c->pending). The memory of c has been freed now, so c->pending is invalid (c is an invalid pointer now), and this will cause memory dump in some platforams(eg: Solaris). So I think the code should be modified as: if (c->pending == 0) { clientDone(c); break; } and this will not lead to while(c->pending).

Before of this commit it used to be like this: MULTI EXEC ... actual commands of the transaction ... Because after all that is the natural order of things. Transaction commands are queued and executed *only after* EXEC is called. However this makes debugging with MONITOR a mess, so the code was modified to provide a coherent output. What happens is that MULTI is rendered in the MONITOR output as far as possible, instead EXEC is propagated only after the transaction is executed, or even in the case it fails because of WATCH, so in this case you'll simply see: MULTI EXEC An empty transaction.
