Bug fix/new feature
Description:
Setting "SEMI" or "STRONG" file close degrees causes problems when multiple
file IDs exist for the same file on disk.
Solution:
Make the "SEMI" and "STRONG" settings only apply to the file ID that is
being closed.
Also, add an "H5F_OBJ_LOCAL" flag for the H5Fget_obj_count() &
H5Fget_obj_ids() calls, so that applications can query about objects opened
with a particular file ID instead of all the objects opened in the file on
disk.

h5committest
Description: See details from Bug #213. Family member file size wasn't saved
anywhere in file. When family file is opened, the first member size determine
the member size.
Solution: This is the third step of checkin. h5repart has been modified. If h5repart is used
to change the size of family member file, the new size(actual member size) is saved in the superblock.
In the second step of checkin, multi driver is checked against the driver
name saved in superblock. Wrong driver will result in a failure with an error message indicating
multi driver should be used. This change includes split driver because it's a special case for multi
driver.
In the first step of checkin. Family member size and name template(unused at this stage) are saved
in file superblock. When file is reopened,the size passed in thrin superblock. A different size
will trigger a failure with an error message indicating the right size. Wrong driver to open family
file will cause a failure, too.

Misc. update:
Description: H5Tget_member_value didn't return correct value if called after
H5Tenum_valueof. It's because there's a sorting on the members of enum type in
H5Tenum_valueof which changed the order of members.
Solution: Made a copy of original type and do sorting on it to protect the
original order.
Platforms tested: fuss; tested v1.6 with h5committest
Misc. update: RELEASE.txt
Description: For variable-length string, H5Tget_class returned H5T_STRING as
its class. But H5Tdetect_class and H5Tget_member_class considered it as
H5T_VLEN. This is fixed to let all these 3 functions treat it as H5T_STRING.
Some test cases have been added to dtypes.c
Platforms tested: heping - already tested for v1.6 with h5committest
Misc. update: RELEASE.txt
Description: The byte order for all 1-byte integer types was fixed as little-endian
even on a big-endian machine. This's corrected in h5detect.c. When types are only
1 byte long, a native int is used substitute the type to detect byte order. Some tools
like h5dump and h5repack are also corrected in this case.

Bug Fix/Code Cleanup/Doc Cleanup/Optimization/Branch Sync :-)
Description:
Generally speaking, this is the "signed->unsigned" change to selections.
However, in the process of merging code back, things got stickier and stickier
until I ended up doing a big "sync the two branches up" operation. So... I
brought back all the "infrastructure" fixes from the development branch to the
release branch (which I think were actually making some improvement in
performance) as well as fixed several bugs which had been fixed in one branch,
but not the other.
I've also tagged the repository before making this checkin with the label
"before_signed_unsigned_changes".

Too minor to require h5committest
Bug fix.
Description:
Address two problems:
- The computation of the scanline in the szip filter was being
performed in the "can apply" callback routine instead of the
"set local" routine.
- The routine which allocated all the chunks for an entire dataset
(which is invoked when the allocation time is early or late,
rather than incremental) wasn't recording a failed filter in
the information for the chunk, causing the library to believe
that the chunk had the filter applied when it really hadn't.
Solution:
- Move the scanline computation to the "set local" callback.
- Record the filter mask with each chunk created when allocating them.

Description:
Added ifdef sections for "H5_USING_PURIFY" in various places in the code,
which are designed to reduce the spurious "uninitialized memory read" warnings
from purify which are actually OK. Note that this macro will have to be
turned on by adding it to the CFLAGS for the build - I didn't think it was
important enough to add a configure flag for.
Also, the changes in H5HG.c optimize the walks through the objects in a
heap to only look at the 'used' entries instead of all the 'allocated' entries.

Description: This is the second step of checkin for encoding and decoding objects.
H5Tencode and H5Tdecode have been committed in the previous step. H5Sencode

Description:
Correct problems with "resurrecting" a dataset in a file. (This occurs
when a dataset which is open gets unlinked from the group hierarchy (making it
"dead" and marked for deletion in the file) and then is re-linked to the group
hierarchy). Note that the current solution applies only to datasets, further
work will fix this for groups and named datatypes also.
Also, fix the "debug" routines to be a little more helpful in certain
situations.
Additionally, fix a locking bug in the symbol table node splitting routine
which could be [one of] the cause[s] of the file corruption in flexible
parallel operation.

Description:
Fix error in chunked dataset I/O where data written out wasn't read
correctly from a chunked, extendible dataset after the dataset was extended.
Also, fix parallel I/O tests to gather error results from all processes,
in order to detect errors that only occur on one process.

Bypass chunk cache for reads as well as writes, if parallel I/O driver is
used and file is opened for writing.

Bug fix
Description:
Correct two problems with variable-length datatypes in datasets:
- When overwriting an entire dataset, writing the fill value to the
file would be skipped, causing problems for VL datatypes when
objects in the file had been unlinked (and thus the space in the
file was not all zeros)
- When an application has set a fill-value for a dataset and the
dataset's datatype contained a VL datatype, the library was filling
space on disk with the memory form of the VL information, instead
of the disk form.
Platforms tested:

h5committest
Bug fix
Description:
When two property lists are compared, the H5Pequal routine was just
comparing the raw information for the property values. This causes problems
when the raw information contains pointers to other information.
Solution:
Allow a 'compare' callback to be registered for properties, so that a user
application get perform the comparison itself, allowing for "deep" compares of
the property value.
This was exported to the H5Pregister & H5Pinsert routines in the development
branch, but not the release branch.

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.

Misc. update:
Purpose: Bug fix
Description: Parameter rdcc_nelmts of the h5pget_cache_f subroutine
had wrong INTEGER(SIZE_T) instead of INTEGER type.
Solution: Fixed the type
Platforms tested: arabica in 64-bit mode (where INTEGER(SIZE_T) is not
the same as INTEGER)
Misc. update:
Bug fix
Description:
The 'char *' type is one of the "strongly" aligned types on Crays, but
a 'void *' is "weakly" aligned. So, assigning a 'void *' (pointing to a
location to place a 'char *') to a 'char **' can change the pointer value
during the assignment.
Solution:
Don't alias the 'void *' where the variable-length information ('char *'
or 'hvl_t') will go. Use a temporary variable on the stack to build up the
information about the VL string or sequence and then memcpy() the temporary
variable directly to the location pointed to with the 'void *'

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.

Improved algorithm (bug fix, sorta)
Description:
The internal algorithm for adding new IDs in the ID manager code (H5I) was
adding new IDs to the front of the linked list and never adjusting the order
of the items on the list (unless an ID was deleted). If many new objects were
created, they would push earlier ones _way_ down the list (especially if the
objects were being leaked in the application, as they appear to be in the
current HDF-EOS5 library) and would cause O(n) search time for items on the
list.
The ID caching code in the ID manager was avoiding this behavior sometimes,
but it was adding IDs that were looked up to the very tail of the cache and
they would frequently leave the cache before helping.
Solution:
Implemented a "move to front" scheme for the linked list of IDs, which
improves the lookup situation for frequently accessed objects.
Removed ID caching code now, as the "move to front" algorithm actually
works better.

Bug fixes and code cleanup
Description:
Lots of changes here:
- Fixed bug #691 - when shared datatypes are used in attributes they
are incorrectly copied into the attribute instead of referring
the the named datatype in the file. This required bumping the
version of the attribute message. The new version of the attribute
message is only written out when a shared datatype is used in
the attribute. [Also, this format change made the size of the
attribute smaller.]
- Added information to attribute debugging routine so that shared
datatypes are displayed correctly with the h5debug tool.
- Refactored the H5O* routines to extract code that was common to
several routines into subroutines to call.
- Added 'link' method for H5O message sub-classes, which increments
the link count on shared objects when a message is created which
shares them.
- Corrected [unreported] bug where the link count was not being
decremented on the shared object when a object header message
with a reference to that object was deleted from the file.
- Reduced size of shared message from 49 bytes (which was incorrect
anyway and should have been 48 bytes) to 10 bytes, which required
bumping the version of "shared" messages.
- Refactored some of the shared datatype routines to allow for easier
queries of "committedness" internally to the library and also
added routine to easily increment/decrement the reference count of
a shared datatype.

Description:
The MPI_File_set_size() routine on ASCI Red is not able to extend files
so that they are larger than 2GB.
Solution:
Add an extra macro which controls whether MPI_File_set_size() can handle
>2GB offsets or if our "older" way of reading a byte, then writing a byte at
the appropriate offset should be used.

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

Solution:
Check the permissions on file IDs that are being closed and only flush
when the particular file ID was opened with write permission.

with fill-values, variable-length datatypes and chunks later on.
Return the rank of the array datatype from H5Tget_array_dims(), like
H5Sget_dims().

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

Improve the sieve buffer clearing code to handle partial invalidations.

not stored in the file.
However, once the file is closed and re-opened, the non-default 'K' value
is lost and the data in the chunked datasets will not be able to be accessed
correctly.
