      Safer handling of MULTI/EXEC on errors. · 3d139127
      antirez authored
      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.

      Fix MULTI / EXEC rendering in MONITOR output. · a1b1c1ea
      antirez authored
      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.

      Support for read-only slaves. Semantical fixes. · f3fd419f
      antirez authored
      This commit introduces support for read only slaves via redis.conf and CONFIG GET/SET commands. Also various semantical fixes are implemented here:
      
      1) MULTI/EXEC with only read commands now work where the server is into a state where writes (or commands increasing memory usage) are not allowed. Before this patch everything inside a transaction would fail in this conditions.
      
      2) Scripts just calling read-only commands will work against read only
      slaves, when the server is out of memory, or when persistence is into an
      error condition. Before the patch EVAL always failed in this condition.

      Take a pointer to the relevant entry of the command table in the client... · 09e2d9ee
      antirez authored
      Take a pointer to the relevant entry of the command table in the client structure. This is generally a more sounding design, simplifies a few functions prototype, and as a side effect fixes a bug related to the conversion of EXPIRE -1 to DEL: before of this fix Redis tried to convert it into an EXPIREAT in the AOF code, regardless of our rewrite of the command.
