      Children creating AOF or RDB files now report memory used by COW. · 49b64523
      antirez authored
      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.

      zmalloc_get_private_dirty() function added (Linux only). · 3bfeb9c1
      antirez authored
      For non Linux systmes it just returns 0.
      
      This function is useful to estimate copy-on-write because of childs
      saving stuff on disk.

      MIGRATE TCP connections caching. · e23d281e
      antirez authored
      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.

      COPY and REPLACE options for MIGRATE. · 1237d71c
      antirez authored
      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.

      REPLACE option for RESTORE. · e5b5763f
      antirez authored
      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.

      Type mismatch errors are now prefixed with WRONGTYPE. · c4b0b685
      antirez authored
      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.

      A filed called slave_read_only added in INFO output. · 89e74abf
      antirez authored
      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.

      redis-check-dump now understands dumps produced by Redis 2.6 · e5f794ff
      Schuster authored
      (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.

      Default memory limit for 32bit instanced moved from 3.5 GB to 3 GB. · c2661ed7
      antirez authored
      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

      Differentiate SCRIPT KILL error replies. · acfe3675
      antirez authored
      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.
