Now that we cache connections, a retry attempt makes sure that the operation don't fail just because there is an existing connection error on the socket, like the other end closing the connection. Unfortunately this condition is not detectable using getsockopt(SO_ERROR), so the only option left is to retry. We don't retry on timeouts.

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.

By caching TCP connections used by MIGRATE to chat with other Redis instances a 5x performance improvement was measured with redis-benchmark against small keys. This can dramatically speedup cluster resharding and other processes where an high load of MIGRATE commands are used.

With COPY now MIGRATE does not remove the key from the source instance. With REPLACE it uses RESTORE REPLACE on the target host so that even if the key already eixsts in the target instance it will be overwritten. The options can be used together.

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.

So instead to reply with a generic error like: -ERR ... wrong kind of value ... now it replies with: -WRONGTYPE ... wrong kind of value ... This makes this particular error easy to check without resorting to (fragile) pattern matching of the error string (however the error string used to be consistent already). Client libraries should return a specific exeption type for this error. Most of the commit is about fixing unit tests.

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.

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.

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.

If the server is password protected we need to accept AUTH when there is a server busy (-BUSY) condition, otherwise it will be impossible to send SHUTDOWN NOSAVE or SCRIPT KILL. This fixes issue #708.

Update src/redis-benchmark.c

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).

The previously used hash function, djbhash, is not secure against collision attacks even when the seed is randomized as there are simple ways to find seed-independent collisions. The new hash function appears to be safe (or much harder to exploit at least) in this case, and has better distribution. Better distribution does not always means that's better. For instance in a fast benchmark with "DEBUG POPULATE 1000000" I obtained the following results: 1.6 seconds with djbhash 2.0 seconds with murmurhash2 This is due to the fact that djbhash will hash objects that follow the pattern `prefix:<id>` and where the id is numerically near, to near buckets. This improves the locality. However in other access patterns with keys that have no relation murmurhash2 has some (apparently minimal) speed advantage. On the other hand a better distribution should significantly improve the quality of the distribution of elements returned with dictGetRandomKey() that is used in SPOP, SRANDMEMBER, RANDOMKEY, and other commands. Everything considered, and under the suspect that this commit fixes a security issue in Redis, we are switching to the new hash function. If some serious speed regression will be found in the future we'll be able to step back easiliy. This commit fixes issue #663.
