Description:
With optimization enabled, gcc 4.8 inserts garbage into the padding bytes of
floating point types when assigning from a literal constant. This caused
problems when H5detect.c scanned the bits in floating point types to determine
their properties.
Modified H5detect.c to scan for padding before further analyzing the type, and
to ignore all information in the padding areas. Also removed code that
temporarily disabled optimization.
Tested: jam, koala, ostrich, platypus (h5committest)
HDFFV-8214 - h5repack failed converting small chunked dataset (size < 1K) to contiguous layout.
Description:
h5repack failed converting small chunked dataset (size < 1K) to contiguous layout.
The first case was when chunk dim is bigger than the dataset dim (at leat one), h5repack failed with displaying error stacks.
The other case is when chunk dim is smaller than the dataset dim, h5repack failed to change layout.
Tested:
jam (linux32-LE), koala (linux64-LE), ostrich (linuxppc64-BE), emu (solaris-BE),fred (mac64-LE), Windows (32-LE cmake), cmake (jam)
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.
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.
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
