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
- h5repack: h5repack failed to copy dataset if the layout is changed from chunked with
unlimited dims to contiguous. (PC -- 2011/07/15)
- h5diff: "--delta" option considers two NaN of the same type are different, which is wrong
based on http://www.hdfgroup.org/HDF5/doc/RM/Tools.html#Tools-Diff. (PC -- 2011/07/15)
Change to use HDxxx macros.
Description:
Originally this started for fixing incorrect pointer usage. But that got
fixed through coverity merge. So this is mainly changing to use HDxxx
macros and clean up some related code.
Tested:
jam (linux32-LE), amani (linux64-LE), heiwa (linuxppc64-BE), tejeda (mac32-LE), linew (solaris-BE)
Clean up Coverity warnings, and fix some style issues:
r19735:
Fix for memory leak in test/mf found by valgrind.
r19736:
Fix memory leak in h5repack. The buffer in copy_objects, when copying the
entire dataset at once, was not checked for the presence of a vlen, and vlen
storage was never reclaimed. Added check and call to H5D_vlen_reclaim().
r19772:
Change H5assert() to
if (H5T_VLEN != src->shared->type || H5T_VLEN != dst->shared->type)
HGOTO_ERROR(H5E_ARGS, H5E_BADTYPE, FAIL, "not a H5T_VLEN datatype")
r19774:
removed unused priv.
r19775:
removed unused variables
r19778:
Fix memory leak comparing for variable length data types.
r19834:
Fixed memory leaks found by valgrind. Memory errors remain for another day.

Added new test expected file for committed bug 1942
r19103, 19104 & 19105:

Description:
h5repack previously would not take named datatypes into consideration when copying
datasets and attributes. This would cause extra anonymous datatypes in the target file
at best, and cause errors halfway through the repacking at worst. h5repack should now
always handle named datatypes correctly. Named datatypes are also now converted to the
native type when -n is given.
Tested: jam, linew, smirom (h5committest)
ISSUE : h5repack does not handle group creation order flags.
ACTION: call H5P(g)(s)et_link_creation_order functions when handling groups, add new groups with these flags to the test generation program, and verify results in the test program.
TEST: in the test program, function that compares property lists, added code to verify groups
tested: windows, linux, solaris
ISSUE : the tools use the following formula to read by hyperslabs: hyperslab_size[i] = MIN( dim_size[i], H5TOOLS_BUFSIZE / datum_size) where H5TOOLS_BUFSIZE is a constant defined of 1024K. This is OK as long as the datum_size does not exceed 1024K, otherwise we have a hyperslab size of 0 (since 1024K/(greater than 1024K) = 0). This affects h5dump. h5repack, h5diff
SOLUTION: add a check for a 0 size and define as 1 if so.
TEST FOR H5DUMP: Defined a case in the h5dump test generator program of such a type (an array type of doubles with a large array dimension, that was the case the user reported). Since the written file commited in svn would be around 1024K, opted for not writing the data (the part of the code where the hyperslab is defined is executed, since h5dump always reads the files). Defined a macro WRITE_ARRAY to enable such writing if needed. Added a run on the h5dump shell script. Added 2 new files to svn: tools/testfiles/tarray8.ddl, tools/testfiles/tarray8.h5. NOTE: while doing this I thought of adding this dataset case to an existing file, but that would add the large array output to those files (the ddls). The issue is that the file list is increasing.
TEST FOR H5DIFF: for h5diff the check for reading by hyperslabs is H5TOOLS_MALLOCSIZE (128 * H5TOOLS_BUFSIZE) or 128 Mb. This makes it not possible to add such a file to svn, so used the same method as h5dump (only write the dataset if WRITE_ARRAY is defined). As opposed to h5dump, the hyperslab code is NOT executed when the dataset is empty (dataset is not read). Added the new dataset to existing files and shell run (tools/h5diff/testfiles/h5diff_dset1.h5 and tools/h5diff/testfiles/h5diff_dset2.h5 and output in tools/h5diff/testfiles/h5diff_80.txt).
TEST FOR H5REPACK: similar issue as h5diff with the difference that the hyperslab code is run. Added a run to the shell script (with a filter, otherwise the code uses H5Ocopy).
tested: linux (h5commitest failed , apparently it did not detect the code changes in /tools/lib that fix the bug: the error in an assertion in the hyperslab of 0. I am sure that making h5ccomitest --distclean will detect the new code , but don't want to wait more 3 hours :-) )
