on Dane and Frontier, which occasionally fails when searching for expected output "Object could not
be found in <h5diff_basic1.h5>" when the object name </nono_obj> is
inserted after "Object". Search string is reduced to "could not
be found".
* 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.
gcc 14 identifies likely places where the sizeof() call is used
for the first parameter to calloc(). This PR fixes the remaining
places in the library where this occurs and reworks a few other
allocations to be more uniform.
Solaris Studio hasn't been updated in almost a decade and the last
version (12.4, circa 2015) doesn't seem to fully support C11.
This PR removes some work-arounds for things like __attribute__()
support.
This is where most people will expect to find license information. The
COPYING_LBNL_HDF5 file has also been renamed to LICENSE_LBNL_HDF5.
The licenses are unchanged.
* 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.
* Clean up random number generator code
Depending on the platform, we use a mix of random, rand, and rand_r
to generate pseudo-random numbers, along with a messy set of ifdefs
in H5private.h. We are not a cryptographic library, only use random
numbers in our test code, and have no need for anything more than the
C standard's (s)rand(). There's no point dithering about using rand()
vs random() when we're also doing bad things like using mod to
restrict the range, which introduces bias.
Also removes CMake/configure checks for rand_r and random
* Remove random/rand_r checks from build system
* Fix missed HDrandom after GitHub merge
The buffers passed to stat-like calls are only partially filled in by
the call, leaving ununitialized memory areas when the stat buffers are
created on the stack.
This change memsets the buffers to 0 before the stat calls, quieting
the -fsanitze=memory complaints.
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
