      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

      initial skeleton for stdio wrapper lib · ebbe6421
      Philip Carns authored
      - move fopen/fopen64 wrappers to stdio module
      - make infrastructure for tracking stream pointers based on similar fd
        infrastructure in posix
      - define placeholder record structs
      - wrappers don't actually do anything yet

      initial runtime lustre module implementation · 657c5b56
      Shane Snyder authored
      the POSIX module will call into the Lustre module for each file
      record created that corresponds to a file from a Lustre FS. No
      counters are currently stored but most of the module strucutre
      has been stubbed.

      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)
