* Fix NULL pointer access when H5A_operator2_t is NULL
Passing NULL for the callback function pointer to H5Aiterate2 and
H5Aiterate_by_name was not detected, leading to a subsequent access
of an uninitialized pointer. Add a check for this "no operator
specified" case in both functions so they fail gracefully instead.
Fixes GHSA-r7g4-hv2f-5c66 - CVE-2025-9274
* Fix format
* Fix Java test to handle NULL callback to H5Aiterate2
Fixes security issue by treating non-NULL buffer with size 0 as length-only query in get_name API functions.
Behavior:
Modify get_name API functions to treat (buffer != NULL, size == 0) as length-only queries, preventing undefined behavior.
Fix applied to H5Aget_name, H5Aget_name_by_idx, H5Fget_name, H5Gget_objname_by_idx, H5Iget_name, H5Lget_name_by_idx, H5Rget_file_name, H5Rget_obj_name, H5Rget_attr_name, and 8 other functions.
Tests:
Update test/links.c, test/tattr.c, test/tfile.c, test/titerate.c, and test/trefer.c to verify new behavior with non-null buffer and size 0.
Documentation:
Update comments in H5A.c, H5F.c, H5Gdeprec.c, H5I.c, H5L.c, H5R.c, and H5Rdeprec.c to reflect new behavior.t]@users.noreply.github.com>
Change default file format to 1.8 across various tests and examples, updating file creation and access logic accordingly.
Behavior:
Default file format version changed to 1.8 in H5Pfapl.c.
Updated file creation and access to use 1.8 format in h5ex_g_compact.c and test_file_image.c.
Set earliest file format in multiple test files including cache_tagging.c, dtypes.c, and links.c.
Tests:
Modified expected output in tools/test/misc/expected/*.ls files to reflect new file format locations.
Adjusted test logic in test_file_image.c and cache_tagging.c to accommodate format changes.
Misc:
Added comments and TODOs for future format testing in test_file_image.c.
Minor variable renaming for clarity in test_file_image.c.
Makes testing parameters specified with AddTest non-const again when
passed to test functions. This allows test functions to update their
parameters during execution and is particularly useful for tests
which use those parameters to accumulate statistics, error counts,
etc. without resorting to global variables.
* 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.
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.
Added new testframe.h header to document testing framework functions and
split them away from h5test.h and from test programs that don't
integrate with the testframe.c testing framework
Added new test setup callback to testframe.c testing framework
Added parameters to AddTest() to specify size of test parameters so they
can be copied for later use
Enabled HDF5 error stacks in testframe.c framework by default and added
some error stack suppressions to some testhdf5 tests
Added new maxthreads option to testframe.c framework to allow specifying
the maximum number of threads a multi-threaded test can use
Moved TestExpress functionality out of testframe.c and into more general
h5test.c for wider use by tests through getter and setter
Updated some tests to not mix and match functionality between h5test.c/h
and testframe.c/h
Moved some functionality from testphdf5.h into testpar.h for parallel
tests that aren't part of testphdf5
Added new parallel test library that contains common shared
functionality for parallel tests (similar to h5test library)
* Fix for github issue #1388: can't delete renamed dense attribute with corder tracking enabled
The problem occurs in step 3(b) below which will delete the attribute with corder x
from the creation order index v2 B-tree.
The rename sequence in H5A__dense_rename() occurs in the following order:
1) The old attribute with corder x was removed from the creation order index v2 B-tree
2) The new renamed attribute was inserted via H5A__dense_insert():
(a) insert the attribute with new name j into the name index v2 B-tree
(b) insert the attribute with corder x into the creation order index v2 B-tree
3) The old attribute was removed via H5A__dense_remove():
(a) remove the attribute with old name k from the name index v2 B-tree
(b) remove the attribute with coorder x from the creation order index v2 B-tree
Fix: deactivate the "corder_bt2_addr" field so that H5A__dense_remove()
won't delete the attribute with corder x from the creation order index v2 B-tree.
* HDF5 API test updates
Removed test duplication from bringing API tests
back into the library from external VOL tests
repo
Synced changes between API tests and library's
tests
Updated API tests CMake code to directly use and
install testhdf5, testphdf5, etc. instead of
creating duplicate binaries
Added new h5_using_native_vol() test function to
determine whether the VOL connector being used
is (or the VOL connector stack being used resolves
to) the native VOL connector
* Remove duplicate variable
* Strip HD prefix from string/char C API calls
* HD(f)(put|get)(s|c)
* HDstr*
* HDv*printf
* HD(s)(print|scan)f
* HDperror
But NOT:
* HDstrcase*
* HDvasprintf
* HDstrtok_r
* HDstrndup
As those are not C99 and have portability work-around
implementations. They will be handled later.

* Add asynchronous token API
* Add new lightweight FUNC_ENTER / LEAVE macros for helping to structure the
threadsafety (H5TS*) routines.
* Sync w/develop
* Initial event set code framework.
* Elaborate on the H5ES routines, starting to add API routines.
Update the "close ID" callbacks to allow asynchronous request tokens to be
passed in from an asynchronous close API call.
Refactor current asynchronous API routines (H5Fopen/H5Fclose and
H5Dread/H5Dread) to use event sets instead of directly working with request
tokens from the application.
Clean up a few other minor warnings & code style issues.
* Implement H5EScreate, H5ESget_count, and H5ESclose.
It should be possible to write a simple application that creates an event
set and uses it with H5Fopen_async, H5Dread_async, H5Dwrite_async, and
H5Fclose_async, then calls H5ESclose (which waits for all async events to
complete).
* Add source file for event set test.
* Refactor sync & async API routines to call common routine.
Move dataset API read / write routines to src/H5D.c, along with all the other
API routines.
Progress on "fake" async VOL connector, for testing.
* Modify async implementation to wrap async requests in a H5VL_object_t
struct so the VOL layer can find the connector when accessing the
request at a later point.
* Free the requests is H5ESclose. Remove comments implying that request
wait, notify, and cancel callbacks should free the request.
* Fix bug in error handling in H5Fclose.
* Fix bugs in async file routines. Rename H5VL_create_object_generic to
H5VL_create_object.
* Add explicit async version of H5Fcreate.
* Add more _async routines
* Correct typo for return value from H5Awrite changes
* Add H5EStest and H5ESwait routines
* Updated with API tracing info
* Fix NULL pointer dereference in H5ES__wait

when the library is shutting down.
* Fix typo
* Remove event from event set's linked list
* Move block of code so that vol_obj is valid
* Avoid setting properties in the DXPL when reseting the library state (and in
the test code).
* Refactor argument tracing to implement new capability for tracing arguments
of non-API routines, with the H5ARG_TRACE macro. This macro is updated
automatically with the bin/trace script that runs as part of the autogen.sh
process. Major changes were in src/H5trace.c and bin/trace, with the other
changes being cleanups to the argument lists, to improve their presentation
in the tracing output.
Also - added the "managed string" routines, which can dynamically allocate
strings, appending printf-formatted output to the string efficiently.
* Release memory for managed strings
* Fix printf() formats.
* More printf() format fixes.
* Add H5Eappend_stack routine and regression tests
* Clean up a few missed merge conflicts and update the error stacks.
* Remove unnecessary fork() operations and ten second sleep().
* Restore commented out attribute out, to better enable tracking down the previous failure
* Allow multiple H5ARG_TRACE macros within a routine to be updated
* Switch to using "new" H5ES_insert (which takes the arguments for the caller routine) for all event set operations. Renames H5ES_insert_new to H5ES_insert and removes the previous H5ES_insert.
* Merge "managed" string routines into "ref-counted" strings, and refactor code to use them.
* Add missing file.
* Add caller's name and arguments to event, for error reporting
* Refactor event set setup for "API common" internal routines
* Checkin async API routines for H5A* and H5G* modules as listed in ID-283.

* Run source formatter
* Change H5TSmutex lock and release to include a lock count
* Update error reporting ideas
* Minor updates to improve sanity checking for retrieving / restoring library state
* Updated with feedback from h5py team members
* Refactor internal event set list and event handling, add implementation for H5ESget_err_info
* Change the VOL request subclass callbacks that switch from using "H5ES_status_t" to "H5VL_request_status_t", and also add a H5VL_request_status_t* parameter to the 'cancel' callback in the request subclass. Also more code quality cleanups to add iterator callbacks to internal event set routines.
* Update API tracing for new H5VL_request_status_t typedef
* Finish converting internal event set operations to use list iterator callbacks, instead of directly accessing the list structure
* Add H5VL_REQUEST_GET_ERR_STACK operation to request subclass, for retrieving a copy of the error stack for a failed asynchronous operation
* Remove 'canceled' event status from Java constants
* Be safer about releasing resources when inserting a newly opened/created object or file into an event set
* Remove H5EStest, add H5ES_WAIT_NONE for 0 timeout, and revise parameters to H5ESwait, to make it more "aggregate".
* Remove H5ES_STATUS_CANCELED from Java wrappers also
* (a) Add async APIs for H5O module as listed in jira issue ID-283.
(b) Remove verification of name parameter in async related routines for H55A and H5L modules
because it is checked in H5VL_setup* routine.
(c) Modify h5dump expected output due to the async changes.
* Corrections based on PR feedback.
* Further changes to make based on PR feedback.
* Fix missed merge marker, and reformatted line
* Clean up some warnings
* Correct level of indirection
* Relocate prototype (and doxygen info) for H5Aclose
* Change non-static function declarations to be static
* Ensure that H5TSpublic.h header gets installed (#129)
* Add 'wrapper' versions of async calls, to allow language wrappers and layers on top of HDF5 to pass in their application information.
* Switch H5Aexists\*_async and H5Lexists\*_async to use flag to return status, instead of return value. Make the corresponding changes through most of the v1 and v2 B-tree code. Clean up warnings in H5public.h and cmpd_dtransform.c.
* Add H5Iregister_future routine and tests.
* Correct return value for H5Lexists_async
