HDFFV-7643 - h5diff - incorrect exit-code returns for extra attribute exist
Description:
h5diff: Fixed to return correct exit code 1 when detect unique
attribute. Prior to this fix, h5diff returned exit code 0 indicating
two files are identical.
Merged from HDF5 trunk r23304.
Tested:
jam (linux32-LE), koala (linux64-LE), ostrich (linuxppc64-BE), fred (mac64-LE), emu (solaris-BE), Windows (32-LE cmake), cmake (jam)
Since this is a testing code error that does not affect the function of the
library or tools, I started a new "Testing" section for this sort of changes.
Purpose: Implement H5Dscatter and H5Dgather
Description:
Adds 2 new API functions, H5Dscatter and H5Dgather. H5Dscatter retrieves data
from a specified callback function and scatters it into a selection, defined by
a supplied dataspace, within a supplied memory buffer. H5Dgather gathers data
from a selection within a supplied memory buffer and passes it in a contiguous
form to a supplied callback function. Added tests for these functions
Tested: jam, ostrich, koala (h5committest); ummon; ummon (1.8)
Merged 23111 from the trunk.
(Core VFD and Mac OS X I/O changes)
Tested on:
64-bit Windows 7, Visual Studio 2010, CMake
64-bit Mac OS X Snow Leopard (Fred), Fortran, C++
64-bit BE Linux (Ostrich), Fortran, C++
32-bit LE LInux (jam), Fortran, C++ (also parallel w/ Fortran)
HDFFV-8145 h5diff slowness with version >= 1.8.7
Description:
Improved speed when comparing HDF5 files with lots of attributes. Much slower performance was identified with release version from 1.8.7 to 1.8.10 compared to 1.8.6.
Merged from HDF5 trunk r22933.
Tested:
jam (linux32-LE), koala (linux64-LE), ostrich (linuxppc64-BE), tejeda (mac32-LE), cmake (jam)
HDFFV-8012 - h5repack changes max dims and cause failure if only "-f none" is used without changing layout for chunked dataset when a chunk dim is bigger than a dataset dim
Description:
"h5repack -f <obj>:NONE <file.h5> out.h5" command failed if source file contains chunked dataset and a chunk dim is bigger than a dataset dim.
Another issue is that the command changed max dims if chunk dim is smaller than the dataset dim.
These issue occurred when dataset size is smaller than 64k (compact size limit)
Fixed them.
Merged from HDF5 trunk r22805
Tested:
jam (linux32-LE), koala (linux64-LE), ostrich (linuxppc64-BE), tejeda (mac32-LE), linew (solaris-BE), Windows (32-LE cmake), cmake (jam)
