* 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
Run configure checks with and without CFLAGS/CMAKE_C_FLAGS since some
compilers work in one case while not working in the other case
Sync CMake configure checks with Autotools
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.
Converts an assertion in H5G_loc_find into a normal error
check that checks for empty link names
Initializes H5O_link_t structure early in H5G__ent_to_link
to avoid trying to free potentially uninitialized memory
Checks for an empty link name after H5MM_strndup in
H5G__ent_to_link
Fixes GitHub #4307
* changed to if string contains instead
* return status of VFDs in libhdf5.settings
* use *_ENABLE_* settings instead to report the state
* added map state
* updated resetting status if cmake option fails
If a corrupt file sets the page buffer size in the superblock to zero,
the library could attempt to divide by zero when allocating space in
the file. The library now checks for valid page buffer sizes when
reading the superblock message.
Fixes oss-fuzz issue 58762
* 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.
Add configure option to enable or disable extension features in general
Add configure option to enable or disable _Float16 support
Add new config options to various settings files
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
H5PB_read previously did not account for the fact that the size of the
read it's performing could overflow the page buffer pointer, depending
on the calculated offset for the read. This has been fixed by adjusting
the size of the read if it's determined that it would overflow the page.
When the H5_addr_overlap macro was updated to use H5_RANGE_OVERLAP,
it failed to take into account that H5_RANGE_OVERLAP expects the
range to be inclusive. This lead to an assertion failure in
H5MM_memcpy due to a memcpy operation on overlapping memory.
This has been fixed by subtracting 1 from the calculated high
bound values passed to H5_RANGE_OVERLAP
