      - match convention of other modules where possible
      - avoid trampoline for non-PMPI calls
      - resolve underlying symbols at run time
      - use symbol name direclty in wrapper

      bug fix for disabling module instrumentation · 37b50d6a
      Shane Snyder authored
      Previously, modules would explicitly disable instrumentation when
      ever Darshan core called into the module to shut it down. The
      issue is that Darshan core starts shutting down well before modules
      do, so there is a time interval where modules could be trying to
      instrument data while its not safe to do so.
      
      Now, we expose a function (darshan_core_disabled_instrumentation)
      that modules can call to determine if its safe to instrument
      data.

      skip instrumentation attempts on anonymous mmap() · 969b6285
      Philip Carns authored
      Anonymous mmap() calls have no backing file and therefore won't match
      any Darshan characterization records, so we can skip the record lookup
      in this case.  This also fixes a deadlock on Cray systems with hugepages
      enabled, see #210.

      modify posix open and close counters · 2276d929
      Shane Snyder authored
      POSIX_F_OPEN_TIMESTAMP is now POSIX_F_OPEN_START_TIMESTAMP
      POSIX_F_CLOSE_TIMESTAMP is now POSIX_F_CLOSE_END_TIMESTAMP
      
      I also added POSIX_F_OPEN_END_TIMESTAMP and
      POSIX_F_CLOSE_START_TIMESTAMP, so we can better understand how
      long open and close phases are for some applications.

      add instrument_fs call to darshan-core · beac22fc
      Shane Snyder authored
      This function can be called by modules to allow FS-specific
      modules to gather data for a given file path/file descriptor.
      Currently integrated into POSIX and STDIO modules.

      bug fix in gathering of lustre fs data · 2770f997
      Shane Snyder authored
      There are cases where lustre stripe info is not available the
      first time a given file is opened (e.g., when using the
      llapi_file_create call). So, now we call into the lustre module
      every time a file is opened to give the module a chance to gather
      data.

      modifications for sorting module records · d599c583
      Shane Snyder authored
      A common record comparision/sort routine is now defined in
      darshan-common which can be used by any modules with fixed-length
      records and whose records first field is the darshan_base_record.
      The comparison was also updated to sort secondarily by darshan
      record identifier to resolve a potential bug in the way we have
      traditionally sorted the records.

      add record_ref interface to darshan-common · 9bfc7b65
      Shane Snyder authored
      This interface provides some convenience functions for mapping
      opaque record identifiers (could be a filename, file descriptor,
      or any other type of file handle) to a corresponding runtime
      structure referencing the actual file record. This runtime
      structure should at least contain a pointer to the actual file
      record, and can also persist arbitrary state for this record.

      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
