      COMP: Add support for newer versions of boost. · 158f4ab5
      Kenneth Leiter authored
      shared_dynamic_cast was deprecated and removed from newer versions of boost
      as dynamic_pointer_cast provides the same functionality. Check at
      configure time whether shared_dynamic_cast exists and if not, then
      provide our own implementation that uses dynamic_pointer_cast.

      BUG: Fix XdmfTopologyConverter to perform node insertion solely · 76a9b916
      Kenneth Leiter authored
      based on connectivity.
      
      Previously, nodes added to a mesh in XdmfTopologyConverter were
      compared using position to ensure nodes added to element boundaries
      were not duplicated (added more than once). This failed in some
      cases, especially for highly refined meshes, because of incorrect
      floating point comparisons. Now, shared nodes are identified using
      connectivity, ensuring that nodal addition should work in all cases,
      even for highly refined meshes.

      ENH: Add methods in Fortran interface to reuse previously added data. · 895f33c5
      Kenneth Leiter authored
      Output of Xdmf data in Fortran can now take advantage of xpointer functionality.
      Calling any AddPrevious or SetPrevious methods will reuse previously
      added Xdmf structure so that when it is written to disk xincludes can be
      utilized rather than rewriting identical structure multiple times.  These
      methods take an id which is returned in Add or Set calls.
      
      Modified TestXdmfFortran.f90 to utilize new functionality.

      ENH: Performance improvements for large reads/writes · 7bcbfe72
      Kenneth Leiter authored
      Eliminate getRealPath calls which are expensive and not necessary in many cases
      Parse XML node content only when necessary (parsing arrays)
      Fix cases where copies were made of strings instead of using references
      Use "map.insert()" rather than "map[] =" when adding properties to map

      ENH: Simplify XdmfArray class. · 3eb2d342
      Kenneth Leiter authored
      Slightly improves compile time on gcc.
      Get rid of mHaveArray and mHaveArrayPointer - rely on blank in variant.
      This reduces code and makes logic easier to understand.

      ENH: Improve performance of hdf5 writes. · decc7dd4
      Kenneth Leiter authored
      Previously, each time a dataset was written to hdf5, the file was opened
      and closed. This was implemented because inside the heavy data writer
      we have no idea whether another dataset will be written, so we don't know
      whether to keep the file open. After profiling large xdmf writes it was
      determined that closing the file appeared to be a bottleneck so hooks were
      added to the heavy data writer to open the file and keep it open while writing.
      This is optional, but was incorporated into several higher level classes
      like XdmfWriter where we know we can leave a file open until we finish writing
      the XML. For our test problem we saw a 7 time performance gain.

      BUG: Fixed resolving file names with protocol added · 294c383c
      Brian Panneton authored
      The bug appears when trying to use a filename given as:
      file:///path/to/xmf/file.xmf and the xmf contains a reference to an h5 file.
      
      - When writing you will end up with a file called 'file:' which contains
      random data.
      - When reading, libxml2 has no problem opening the xml file however
      getRealPath() returns the wrong path for the h5 file. If you try to
      use file.xmf from the to directory (ie: read("to/xmf/file.xmf")) the
      h5 file will be loaded from 'to/file.h5'.
      
      To correct the issue, we strip out the unwanted scheme and other stuff
      in the URI and just use the path. (libxml has functions for this)

      BUG: Fix bug when pulling in href'd xincludes. · 4fe61475
      Kenneth Leiter authored
      Additional xmf files are now read in via href'd xincludes which broke
      mapping of xmlNodePtrs to XdmfItems (which qas necessary to enable shared
      pointer representation in file).  This mapping was fixed.

      BUG: Fix infinite loop in XdmfCoreReader.cpp · d11ee071
      Kenneth Leiter authored
      XdmfCoreReader.cpp had a bug that resulted in an infinite loop when
      resolving xincludes. This bug was fixed. Added ability for xincludes
      to resolve href links (links to other files).
      
      Fixed formatting in XdmfWriter.cpp
