* 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
Fixes an issue where invalid datatype IDs are passed to application conversion
functions in the case where the top-level conversion function is a library-internal
function that operates on a container-like datatype, but one or more of the
base datatype members are converted with an application conversion function.
* Fix bug in array conversion with strided background buffer. Convert some
memmove calls to non-overlapping buffers to memcpy.
* Revert inappropriate use of mempy to memmove in H5T__conv_array
* Add testing
* Add RELEASE.txt note and overwrite test case.
This API call sets the size of a file's page buffer cache. This call
was extremely strict about matching its parameters to the file strategy
and page size used to create the file, requiring a separate open of the
file to obtain these parameters.
These requirements have been relaxed when using the fapl to open
a previously-created file:
* When opening a file that does not use the H5F_FSPACE_STRATEGY_PAGE
strategy, the setting is ignored and the file will be opened, but
without a page buffer cache. This was previously an error.
* When opening a file that has a page size larger than the desired
page buffer cache size, the page buffer cache size will be increased
to the file's page size. This was previously an error.
The behavior when creating a file using H5Pset_page_buffer_size() is
unchanged.
Fixes GitHub issue #3382
Both H5Dchunk_iter() and H5Dget_chunk_info(_by_coord)() did not take
the size of the user block into account when reporting addresses. Since
the #1 use of these functions is to root around in the file for the raw
data, this is kind of a problem.
Fixes GitHub issue #3003
When building with debug symbols on MacOS, the cp -p commands in
test_plugin.sh will attempt to copy the .dSYM directories with
debugging info, which will fail since -r is missing.
Using cp -rp is harmless and allows the test to run
Fixes HDFFV-10542
Changes Autotools testing to use HDF5_TEST_DRIVER environment
variable to avoid running tests that don't work well with several
VFDs
Restores old h5_get_vfd_fapl() testing function to setup a FAPL
with a particular VFD
Adds a macro for the default VFD name
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.
* Fixes detection of various Windows libraries, etc.
* Corrects alarm(2) configure checks
* Uses Win32 threads by default w/ Pthreads override, if desired
* Set _WIN32_WINNT correctly for MinGW
* Fix setenv(3) wrapper for MinGW, which does not have getenv_s()
MinGW Autotools support is still not Amazing, but this at least
allows the library and tools build and is better about thread-safety
Removes some datatype copying calls that are now unnecessary after
refactoring the datatype conversion code to use pointers internally
rather than IDs
Rewrites the enum conversion function so that it uses cached copies
of the source and destination datatypes in order to avoid modifying
the datatypes passed in
Adds a 'recursive' field to the datatype conversion context which
allows the conversion functions for members of a container datatype
to skip unnecessary repetitive conversion setup code
Changes internal datatype conversion callback functions so that the
source and destination datatype structure pointers are const
Removes some unused and unnecessary internal IDs registered with
H5I_register
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
The reference manual states that the offset parameter of H5Soffset_simple()
can be set to NULL to reset the offset of a simple dataspace to 0. This
has never been true, and passing NULL was regarded as an error.
The library will now accept NULL for the offset parameter and will
correctly set the offset to zero.
Fixes HDFFV-9299
The datatype conversion code previously used IDs for the source and
destination datatypes rather than pointers to the internal structures
for those datatypes. This was mostly due to the need for an ID for these
datatypes that can be passed to an application-registered datatype
conversion function or datatype conversion exception function. However,
using IDs internally caused a lot of unnecessary ID lookups and hurt
performance of datatype conversions in general. This was especially
problematic for compound datatype conversions, where the ID lookups were
occuring on every member of every compound element of a dataset. The
code has now been refactored to use pointers internally and only create
IDs for datatypes when necessary.
Fixed a test issue in dt_arith where a library datatype conversion
function was being cast to an application conversion function. Since the
two have different prototypes, this started failing after the parameters
for a library conversion function changed from hid_t to H5T_t * and an
extra parameter was added. This appears to have worked coincidentally in
the past since the only different between a library conversion function
and application conversion function was an extra DXPL parameter at the
end of an application conversion function
Fixed an issue where memory wasn't being freed in the h5fc_chk_idx test
program. Even though the program exits quickly after allocating the
memory, it still causes failures when testing with -fsanitize=address
When clearing out datatype conversion paths involving variable-length or reference datatypes
on file close, also check for these datatypes inside compound or array datatypes
* Fixed asserts due to H5Pset_est_link_info() values
If large values for est_num_entries and/or est_name_len were passed
to H5Pset_est_link_info(), the library would attempt to create an
object header NIL message to reserve enough space to hold the links in
compact form (i.e., concatenated), which could exceed allowable object
header message size limits and trip asserts in the library.
This bug only occurred when using the HDF5 1.8 file format or later and
required the product of the two values to be ~64k more than the size
of any links written to the group, which would cause the library to
write out a too-large NIL spacer message to reserve the space for the
unwritten links.
The library now inspects the phase change values to see if the dataset
is likely to be compact and checks the size to ensure any NIL spacer
messages won't be larger than the library allows.
Fixes GitHub #1632
* Fix copy-paste comments
- Close/reopen file and file objects to prevent cache from being used instead of actual I/O.
- Moved vlen io test datasets under the dset container group instead of the root group
- Moved the PASSED() invocation to after individual test cleanup in case an error occurs during H5Treclaim
Compound fill values were set to the integer -1, causing valgrind
to flag 'uninitialized bytes' errors.
This is just a problem with the cmpd_dset test and not a core
library problem.
