Bug fix
Description:
Variable length strings and sequences with NULL pointers were not handled
by library, causing problems access the data. This also affected fill values
for variable-length datatypes.
Solution:
Address the issues in the library by detecting NULL sequences/strings
and avoid trying to convert them.
Patched up dumper to display NULL sequences/strings.

Bug fix & code cleanup
Description:
Allowing the library to call malloc with a size of 0 bytes causes problems
for some users, so we check for allocations of 0 bytes and disallow them now.
Cleaned up some code which could call malloc with 0 size.
Changed some code calling HDmalloc directly to call H5MM_malloc(), which
allows us to check for 0 sized allocations.

Bug fix
Description:
Single hyperslab selections (which were set with only one call to
H5Sselect_hyperslab) that had dimensions that could be "flattened" but were
interspersed with dimensions that could not be flattened were not correctly
handled, causing core dumps.
Solution:
Re-work "flattening" code to handle this case properly.

Bug fix
Description:
The tests recently added for checking a file's freespace and verifying the
new fields added to the H5G_stat_t structure use H5T_NATIVE_INT as the type for
the datasets and attributes they create. Because the tests check explicit file
sizes, this causes problems on Crays, where a native int is 64-bit instead of
32-bit.
Solution:
Change the tests to use H5T_STD_U32LE instead of H5T_NATIVE_INT.
Platforms tested:

Bug fix
Description:
When too many messages were inserted into an object header, the library
had an internal pointer to the "new message" that was pointing to the incorrect
location when the array of messages was re-allocated.
In the worst case, this could cause a file to be corrupted.
Solution:
Update the internal pointer when the array is re-allocated.

itself).

Bug fixes and code cleanup
Description:
Re-worked ohdr test to use modification time messages instead of symbol
table messages, now that the library correctly tries deleting the
local heap and B-trees for the symbol tables (which didn't exist and
caused the test to fail).
Added tests for using named datatypes in attributes to verify that the
reference counts are being tracked correctly, etc.

output. The file names and line numbers in the messages can be different
for users.
Solution: Temporarily disable the test until find a good solution.
Platforms tested: None. Disabling a test.
Code cleanup, etc.
Description:
Generalize Ray's datatype fixes to handle packing compound datatypes which
are the base type of an array or variable-length type, etc.
Also track "packedness" of a compound datatype from it's creation, instead
of only setting the 'packed' flag after the datatype was explicitly packed.
Updated docs to reflect that a compound datatype is allowed to grow (but
not shrink).

Bug fix.
Description:
Correct bug where a file opened twice, once with read-write permission
and once with read-only permission would cause closing the file with the
read-only file ID to fail because it was trying to flush information out
of the file.
Solution:
Check the permissions on file IDs that are being closed and only flush
when the particular file ID was opened with write permission.

Description:
The VFL driver ID in a file's access proprty list wasn't being reference
counted correctly, causing the VFL driver to get prematurely closed after

list is made in H5Pget_access_plist()

Bug Fix and code cleanup
Description:
Correct error in H5T_detect_class that was causing nested compound datatypes
with to not detect the datatype class of fields correctly, which caused errors
with fill-values, variable-length datatypes and chunks later on.
Return the rank of the array datatype from H5Tget_array_dims(), like
H5Sget_dims().
Lots of cleanups to datatype code, to make the handling of arrays, compound
types, variable-length strings and sequences and enumerated types more
consistent and robust.

Bug fix
Description:
When datasets are deleted from a file, they are removed from the sieve
buffer, but instead of invalidating only the part of the sieve buffer affected,
the sieve buffer code would throw away the entire sieve buffer, potentially
including other raw data in the buffer that hadn't been written to disk yet.
Solution:
Improve the sieve buffer clearing code to handle partial invalidations.

Description:
H5Gget_objname_by_idx should allow NULL for the 'name' parameter, to allow
