1) added a new parameter to the h5diff function diff_array that contains the beginning position of the hyperslab, so that the total position in the array is printed correctly when reading by hyperslabs. 2) added a new test to h5diff that reads and diffs by hyperslabs. The test reads a 1GB dataset, from which a 1KB hyperslab was written with differences . 3) added the generation of 2 files to the generator program to test the h5diff hyperslab read. 4) changed the h5diff binary pre-generated file names to be more descriptive (e.g, instead of file1.h5, made it h5diff_basic1.h5) 5) changed the name of the h5repack options text file to info.h5repack

usage: h5diff file1 file2 [OPTIONS] [obj1[obj2]]
|
|
|
|
file1 File name of the first HDF5 file
|
|
file2 File name of the second HDF5 file
|
|
[obj1] Name of an HDF5 object, in absolute path
|
|
[obj2] Name of an HDF5 object, in absolute path
|
|
[OPTIONS] are:
|
|
[-h] Print out this information
|
|
[-r] Report mode. Print the differences
|
|
[-v] Verbose mode. Print the differences, list of objects, warnings
|
|
[-q] Quiet mode. Do not do output
|
|
[-n count] Print difference up to count number
|
|
[-d delta] Print difference when it is greater than limit delta
|
|
[-p relative] Print difference when it is greater than a relative limit
|
|
|
|
Items in [] are optional
|
|
[obj1] and [obj2] are HDF5 objects (datasets, groups, datatypes or links)
|
|
The 'count' value must be a positive integer
|
|
The 'delta' and 'relative' values must be positive numbers
|
|
The -d compare criteria is |a - b| > delta
|
|
The -p compare criteria is |1 - b/a| > relative
|
|
|
|
h5diff has four modes of output:
|
|
Normal mode: print the number of differences found and where they occured
|
|
Report mode: print the above plus the differences
|
|
Verbose mode: print the above plus a list of objects and warnings
|
|
Quiet mode: do not print output (h5diff always returns an exit code of 1 when differences are found)
|
|
|
|
Examples of use:
|
|
|
|
1) h5diff file1 file2 /g1/dset1 /g1/dset2
|
|
|
|
Compares object '/g1/dset1' in file1 with '/g1/dset2' in file2
|
|
|
|
2) h5diff file1 file2 /g1/dset1
|
|
|
|
Compares object '/g1/dset1' in both files
|
|
|
|
3) h5diff file1 file2
|
|
|
|
Compares all objects in both files
|
|
|
|
Note) file1 and file2 can be the same file. Use
|
|
|
|
h5diff file1 file1 /g1/dset1 /g1/dset2
|
|
|
|
to compare '/g1/dset1' and '/g1/dset2' in the same file
|
|
|
|
If no objects are specified, h5diff only compares objects with the same absolute path in both files. The compare criteria is: 1) datasets: numerical array differences 2) groups: name string difference 3) datatypes: the return value of H5Tequal 2) links: name string difference of the linked value
