      RDB modules values serialization format version 2. · 365dd037
      antirez authored
      The original RDB serialization format was not parsable without the
      module loaded, becuase the structure was managed only by the module
      itself. Moreover RDB is a streaming protocol in the sense that it is
      both produce di an append-only fashion, and is also sometimes directly
      sent to the socket (in the case of diskless replication).
      
      The fact that modules values cannot be parsed without the relevant
      module loaded is a problem in many ways: RDB checking tools must have
      loaded modules even for doing things not involving the value at all,
      like splitting an RDB into N RDBs by key or alike, or just checking the
      RDB for sanity.
      
      In theory module values could be just a blob of data with a prefixed
      length in order for us to be able to skip it. However prefixing the values
      with a length would mean one of the following:
      
      1. To be able to write some data at a previous offset. This breaks
      stremaing.
      2. To bufferize values before outputting them. This breaks performances.
      3. To have some chunked RDB output format. This breaks simplicity.
      
      Moreover, the above solution, still makes module values a totally opaque
      matter, with the fowllowing problems:
      
      1. The RDB check tool can just skip the value without being able to at
      least check the general structure. For datasets composed mostly of
      modules values this means to just check the outer level of the RDB not
      actually doing any checko on most of the data itself.
      2. It is not possible to do any recovering or processing of data for which a
      module no longer exists in the future, or is unknown.
      
      So this commit implements a different solution. The modules RDB
      serialization API is composed if well defined calls to store integers,
      floats, doubles or strings. After this commit, the parts generated by
      the module API have a one-byte prefix for each of the above emitted
      parts, and there is a final EOF byte as well. So even if we don't know
      exactly how to interpret a module value, we can always parse it at an
      high level, check the overall structure, understand the types used to
      store the information, and easily skip the whole value.
      
      The change is backward compatible: older RDB files can be still loaded
      since the new encoding has a new RDB type: MODULE_2 (of value 7).
      The commit also implements the ability to check RDB files for sanity
      taking advantage of the new feature.

      Modules TSC: use atomic var for server.unixtime. · 1f598fc2
      antirez authored
      This avoids Helgrind complaining, but we are actually not using
      atomicGet() to get the unixtime value for now: too many places where it
      is used and given tha time_t is word-sized it should be safe in all the
      archs we support as it is.
      
      On the other hand, Helgrind, when Redis is compiled with "make helgrind"
      in order to force the __sync macros, will detect the write in
      updateCachedTime() as a read (because atomic functions are used) and
      will not complain about races.
      
      This commit also includes minor refactoring of mutex initializations and
      a "helgrind" target in the Makefile.

      atomicvar.h: show used API in INFO. Add macro to force __sync builtin. · de786186
      antirez authored
      The __sync builtin can be correctly detected by Helgrind so to force it
      is useful for testing. The API in the INFO output can be useful for
      debugging after problems are reported.
