H5Ztrans: (feature) Improved H5Z_xform_noop() and H5Z_xform_create() … (#933)
* H5Ztrans: (feature) Improved H5Z_xform_noop() and H5Z_xform_create() function
- Made a small improvement for H5Z_xform_noop() function. Now,
the function will also return TRUE if the data transform function
expression = "x". For this case, the HDF5 library behaves in a
similar fashion as the case when no data transform function has been
specified.
- Improved the inline documentation of the function
H5Z_xform_create() such it is more inline with the rest of the
code.
* Committing clang-format changes
* H5Ztrans: (feature) Added 3 tests for improved H5Z_xform_noop() function
- Added serial test with data transform expression = "x" to
verify the improved H5Z_xform_noop() function behaves as expected.
- Added 2 parallel tests with data transform expression = "x"
in combination with a filter. Before, these tests will fail but
with the improved H5Z_xform_noop() function they work and result
in the expected behavior.
- Small bug fix for one of parallel filter tests.
* Committing clang-format changes
* H5Ztrans: (feature) Added release note about detection of the
simple data transform function "x".
- Added a brief explanation about the implemented improvement
of the detection of the simple data transform function "x"
to the RELEASE.txt file.
