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-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.
Tested:
jam (linux32-LE), koala (linux64-LE), ostrich (linuxppc64-BE), tejeda (mac32-LE), linew (solaris-BE), Windows (32-LE cmake), cmake (jam)
Changes resulting from Klocwork static analysis tool, from Mark Miller
@ LLNL (miller86@llnl.gov).
Tested on:
Mac OS X/64 10.7.4 (amazon) w/debug, C++ & FORTRAN, using gcc 4.7.x
(too minor to require h5committest)
Fix for HDFFV-8107 testh5diff will fail if build/test in HDF5 source tree
Description:
This is sub-task for "HDFFV-8105 testh5diff.sh uses the wrong operator (-a) in an if statement."
From the HDFFV-8105's update, h5diff test failed if build&test is performed in HDF5 source tree because 'cp' try to copy test files to self dir.
It's addressed by skipping if cp's src dir and dest dir is same.
Also this applied for all other tools under src/tools dir.
No change to the CMakeLists.txt files because CMake cautions/demands that in-source builds be avoided.
Tested:
jam (linux32-LE), koala (linux64-LE), ostrich (linuxppc64-BE), tejeda (mac32-LE), linew (solaris-BE), some manual tests as well
Fix h5repacktst (test file generating binary) to address HDFFV-8016 h5repacktst failed in AIX 32bit mode
Description:
Segmentation fault occurred when h5repacktst try to generate a dataset when
system memory is limited to 256MB.
Add error handling to display apporiate message to exit and adjust the test
dataset according to the original size which didn't causing out of memory.
Tested: test was done by limit memory in csh.
jam (linux32-LE), koala (linux64-LE), ostrich (linuxppc64-BE)
Fix for HDFFV-7993 - h5repack fails with error "chunk size must be <= maximum dimension size for fixed-sized dimensions"
Description:
Fixed a failure when change the chunk size of a specified chunked dataset with unlimited max dims.
Also took care of converting to contiguous and compact from the dataset.
Test cases were added and tagged with jira#.
Tested:
jam (linux32-LE), koala (linux64-LE), ostrich (linuxppc64-BE), tejeda (mac32-LE), linew (solaris-BE), Windows (32-LE cmake), Cmake (jam)
Clean up a few warnings and use constant values for free-space
parameters for the metadata block size test.
Tested on:
Linux/64 2.6.18 (koala) w/production & szip
(h5committested also)
Add new "metadata block size" command line option ('-M <x>' or
'--metadata_block_size=<x>') for h5repack.
Tested on:
Mac OSX/64 10.7.3 (amazon) w/debug)
(h5committest upcoming)
Task for HDFFV-7862 - Select data by chunk direction to improve performance in h5repack
Description:
h5repack sometimes became very slow when handling big chunked datasets in
certain cases. (when chunk boundary doesn't match with a hyperslab boundary.)
The main issue was from figuring out a hypeslab without considering chunk
boundary to read from and write to such datasets.
The update was made to figure out a better hyperslab unit with considering
chunk boundary to improve performance for such cases prior to the update.
Tested:
jam (linux32-LE), koala (linux64-LE), ostrich (linuxppc64-BE), tejeda (mac32-LE), linew (solaris-BE), Windows
