Summary: when using h5diff to compare the results of h5repack (or other tools that copy one HDF5 file to another), a new option is needed to allow h5diff to make an "absolute" comparison of the 2 files. This is the "contents" mode explained in the usage below. If this mode is present, objects in both files must match (must be exactly the same). If this does not happen, the tool returns an error code of 1 (instead of the success code of 0) Changes to the h5repack test script: the call to h5diff was changed to include -c (maintaining the previous -q). tested: windows, linux, solaris

usage: h5diff [OPTIONS] file1 file2 [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
|
|
-h, --help Print a usage message and exit
|
|
-V, --version Print version number and exit
|
|
-r, --report Report mode. Print differences
|
|
-v, --verbose Verbose mode. Print differences, list of objects
|
|
-q, --quiet Quiet mode. Do not do output
|
|
-c, --contents Contents mode. Objects in both files must match
|
|
-n C, --count=C Print differences up to C number
|
|
-d D, --delta=D Print difference when greater than limit D
|
|
-p R, --relative=R Print difference when greater than relative limit R
|
|
|
|
C - is a positive integer
|
|
D - is a positive number. Compare criteria is |a - b| > D
|
|
R - is a positive number. Compare criteria is |(b-a)/a| > R
|
|
|
|
Modes of output:
|
|
|
|
Default mode: print the number of differences found and where they occured
|
|
-r Report mode: print the above plus the differences
|
|
-v Verbose mode: print the above plus a list of objects and warnings
|
|
-q Quiet mode: do not print output
|
|
-c Contents mode: objects in both files must match
|
|
|
|
Compare criteria
|
|
|
|
If no objects [obj1[obj2]] are specified, h5diff only compares objects
|
|
with the same absolute path in both files. However,
|
|
when the -c flag is present, (contents mode) the objects in file1
|
|
must match exactly the objects in file2
|
|
|
|
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
|
|
|
|
Return exit code:
|
|
|
|
1 if differences found, 0 if no differences, -1 if error
|
|
|
|
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
