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
Bug fix: for compound types, the not comparable test for members was not done
Solution: for compound types, recursively apply that check
Two new cases are added
1) the compound type has a different number of members. Message printed is
<obj1> has X members <obj2> has Y members
Where X and Y are the number of members of each compound type being compared
2) the compound type has not comparable types (for example a double and an int at the same index)
In this case the message
Comparison not possible: object1 is of class1 and object2 is of class2
Is replaced with
Comparison not possible: object1 has a class1 and object2 has a class2
Modified the test generator program to have these 2 cases
Added a shell run for these 2 cases
Tested: h5committest
bug fix
a new line was not inserted at the end of output, causing diff to complain between linux and frebsd
tested: linux (freebsd tested on the trunk)
#1368 (E1) h5diff: implement "not comparable" messages. Implemented RFC. The new option is <-c, --compare List objects that are not comparable>
added some test cases
tested: windows, linux
Added an option to avoid dealing with NaNs
-N, --nan Avoid NaNs detection
Note: there is no shell script run for datasets with NaN because the output is non portable (different results and NaN strings for different systems)
Tested: windows, linux
Bug fix
PG compiler complains about array out of bounds (a rank of zero was not checked)
Adding a scalar dataset to the test generator program. this case is run on a previous existing run, the case was added to 2 existing files
Tested: windows, linux
