      darshan-core code and documentation cleanup · d8f3575a
      Shane Snyder authored
      Cleanup the structure and documenation of the code to be in sync
      with the new mmap version of Darshan. In particular, I made sure
      all extra mmap logic was properly ifdef wrapped so it's more clear
      which portions of the code are responsible for implementing that
      feature.

      numerous darshan-core api changes · bfde9eb7
      Shane Snyder authored
      - memory management is now entirely handled by darshan-core for
        module records
          * when registering new records, darshan-core returns the
            corresponding buffer to write it to, rather than allowing
            module to determine this
      - modules now decide whether darshan-core should track record
        names by passing either a valid name or NULL to the register
        function
          * this allows modules to register records that aren't really
            tracked by darshan-core
      - only the POSIX module has been ported to new changes for this

      update how module & record registration · d3fae782
      Shane Snyder authored
      - modules now receive a memory buffer after successfully
      registering with darshan-core. modules can request a specific
      memory amount, but may not be honored depending on the configured
      darshan memory limit
      - split the previous register_record function into 2 parts:
          * lookup() -> lookup darshan_record_id corresp. to path name
          * register() -> register record_id & name with darshan-core
      - register_record now returns true if the record added; false
      otherwise (if module was out of memory or darshan is out of memory
      for storing id->name mappings)

      update core runtime record hash implementation · 523b19e4
      Shane Snyder authored
      Now, as the app executes, darshan-core persists the id->name
      mapping data to the tmp log file. This is done by serializing the
      id->name mapping to the mmap log file region when new records are
      registered.

      Complete (first) implementation for darshan · da477e42
      Shane Snyder authored
      -darshan-core:
          - initializes darshan job data structures
          - creates log file
          - writes job info header
          - reduces which modules were used locally/globally
          - shut down and write out individual modules one by one
      
      -darshan-posix:
          - register w/ darshan-core and allocate allowed memory
          - track open counter and timestamp for opened files
          - provide file record buffer at shutdown
      
      Major TODOs:
          - shared file reductions (prefer reusable across modules)
          - register handles with darshan file_ids (prefer reusable)
          - generic compression of module buffers (zlib/bzip2)
          - write out map of filenames to darshan ids
          - modify darshan-util and add darshan-posix parser to read logs
