Fix for Bug1896 h5repack - changing layout to COMPACT does not work
Description:
Merged from hdf5 trunk (r19389)
Make h5repack be able to convert a layout to COMPACT for small size dataset as default. Also add verifying layout changes in our test script.
Tested:
jam, amani
Fix for bug1814 - NPOESS: h5repack doesn't handle references to the groups
as an element of a dataset
Description:
Merged from hdf5 trunk r18425
handles object reference to named-datatype as well.
Add test cases.
Tested:
jam
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)
1. #1501 (B1) tools bug if dataset is larger than H5TOOLS_BUFSIZE limit.
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).
FURTHER ISSUES: the type in question ("double") has a different output cross platforms (e.g on liberty some garbage number is printed at some array locations)
SOLUTION: defined an "int" type for this test. However the printing of such an array has a bogus output at least in one platform (FreeBsd), so eliminated the test run altogether and filed a bug report on this
Bring r16401 back from trunk:
Correct error introduced in r16353 with layout version, and add test
so it gets caught earlier.
Tested on:
FreeBSD/32 6.3 (duty)
Too minor to require h5committest
