jhendersonHDF 57128d33b2 Fix h5ls issue with quoting when displaying integer data as ASCII characters (#6553)
When using the '-s' (h5ls) or '-r' (h5dump) option to display 1-byte integer datasets and attributes as ASCII characters, a closing double-quote character for data values was dropped in some cases.

4891139ebd Updated h5dump --xml (#6394)
* Updated h5dump --xml

The location of the files HDF5-File.xsd and HDF5-File.dtd no longer exists, and
the files were added to the repo (PR #5490).  Before the --xml is actually removed,
running the h5dump tests will fail.  This PR updated h5dump and the expected output
to use the correct files' location and actually completed the ticket HELP-2668.

* Added missing expected files from the previous commit

* Fixed typo

* Made corrections per review feedbacks

* Committing clang-format changes

* Missing files from previous commit

* Use valid URL for xmlns

found

jhendersonHDF 90429f5e7d Implement support for complex number datatypes (#4630)
* Implement support for complex number datatypes

Adds the new datatype class H5T_COMPLEX

Adds the new API function H5Tcomplex_create which creates a complex
number datatype from an ID of a base floating-point datatype

Adds the new feature check macros H5_HAVE_COMPLEX_NUMBERS and
H5_HAVE_C99_COMPLEX_NUMBERS

Adds the new datatype size macros H5_SIZEOF_FLOAT_COMPLEX,
H5_SIZEOF_DOUBLE_COMPLEX and H5_SIZEOF_LONG_DOUBLE_COMPLEX

Adds the new datatype ID macros H5T_NATIVE_FLOAT_COMPLEX,
H5T_NATIVE_DOUBLE_COMPLEX, H5T_NATIVE_LDOUBLE_COMPLEX,
H5T_CPLX_IEEE_F16LE, H5T_CPLX_IEEE_F16BE,
H5T_CPLX_IEEE_F32LE, H5T_CPLX_IEEE_F32BE,
H5T_CPLX_IEEE_F64LE and H5T_CPLX_IEEE_F64BE

Adds hard and soft datatype conversion paths between complex number
datatypes and all the integer and floating-point datatypes, as well as
between other complex number datatypes

Adds a special conversion path between complex number datatypes and
array or compound datatypes where the in-memory layout of data is the
same between the datatypes and data can be converted directly

Adds support for complex number datatypes to the h5dump, h5ls and
h5diff/ph5diff tools. Allows h5dump '-m' option to change floating-point
printing format for float complex and double complex datatypes, as well
as long double complex if it has the same size as double complex

Adds minimal support to the h5watch and h5import tools

Adds support for the predefined complex number datatypes and
H5Tcomplex_create function to the Java wrappers. Also adds initial,
untested support to the JNI for future use with HDFView

Adds support for just the H5T_COMPLEX datatype class to the Fortran
wrappers

Adds support for the predefined complex number datatypes and
H5Tcomplex_create function to the high level library H5LT interface
for use with the H5LTtext_to_dtype and H5LTdtype_to_text functions

Changes some usages of "complex" in the library since it conflicts with
the "complex" keyword from the complex.h header. Also changes various
usages of the word "complex" throughout the library to distinguish
compound datatypes from complex datatypes.

vchoi-hdfgroup b23affc2a6 Fix for github issue #3790: infinite loop closing library (#4445)
* Fix for github issue #3790: infinite loop closing library
Cause of the problem:
When h5dump tries to open the user provided test file, the metadata cache will
call the "get_final_load_size" callback to find out the actual size of the
the root object header.  The callback function will call
H5O__prefix_deserialize() to allocate space for the object header
data structure (via H5FL_CALLOC) and to deserialize the object header prefix
in order to find the actual size of the object header.
The metadata cache will then check whether the actual size obtained
will exceed the file's EOA.
Since the actual size obtained from the test file exceeds the EOA,
the metadata cache throws an error and return.
However, the oh structure that was allocated in H5O__prefix_deserialize()
was not freed and hence causing the problem described in this issue.
Fix:
1) Deallocate the oh structure after obtaining and saving the needed
information in udata which will be used later on in the "verify_chksum" callback.
2) Deserialize the object header prefix in the "object header's
"deserialize" callback regardless.  The original coding intends to keep the
deserialized prefix so that the object header's "deserialize" callback
does not need to deserialize the prefix again if the object header is coming
through the "get_final_load_size" callback.

jhendersonHDF 330b80a266 Add support for _Float16 16-bit floating point type (#4065)
Fixed some conversion issues with Clang due to problematic undefined
behavior when casting a negative floating-point value to an integer

Fixed a bug in the library's software integer to floating-point
conversion function where a user's conversion exception function
returning H5T_CONV_UNHANDLED in the case of overflows would result in
incorrect data after conversion

Added configure checks for functions and macros related to _Float16
usage since some compilers expose the datatype but not the functions or
macros

Fixed a dt_arith test failure when H5_WANT_DCONV_EXCEPTION isn't defined

Fixed a few warnings from not explicitly casting some _Float16 variables
upwards
