Purpose:
HDF5 now supports SZIP with no encoder.
Description:
SZIP can be configured to have both encoder and decoder or just to have the decoder. HDF5 can now query the configuration of any filter, and will throw errors if users try to write using a filter with encoding disabled.
Solution:
Added H5Zget_filter_info function, changed API for H5Pget_filter and H5P_get_filter_by_id. See SZIP RFC.
Platforms tested:

Misc. update:
Purpose:
Small H5I API changes.
Description:
Changed public version of H5Inmembers to return the number of IDs in a
type by reference. This allows the user to differentiate between the
case when H5Inmembers has an error and when the ID type is just empty.
Added a new API function, H5Itype_exists, which allows the user to
find out whether an ID type exists or not, without throwing an error.
Solution:
Platforms tested:
Copper
Misc. update:
Description: Added new API H5Fget_name and new test program called filename.c. This function
returns the name of the file by object ID(file, group, dataset, named datatype, and attribute)
which belongs to the file.

Description:
Re-work the way interface initialization routines are specified in the

Description:
Make bug fix for detecting the type of a soft link more general by
registering an "isa" function for soft links.
Platforms tested:
FreeBSD 4.10 (sleipnir)
Too minor to require h5committest
Description: Function H5Gget_objtype_by_idx failed to handle soft link
object. The library returned object type by calling H5G_get_type through
H5B_iterate. But H5G_get_type only deals with objects with valid header address
which soft link doesn't have.
Solution: In H5G_node_type, make soft link a special case by checking if
the object type is H5G_CACHED_SLINK. Also added a test of soft and hard links
to titerate.c
Platforms tested: h5committest and RH 8(fuss).
Description: This is an enhancement after a user reported data writing failure
for array datatype of compound type with variable-length type in the v1.6 branch.
Solution: Added new test and ran with Purify. Fixed memory errors and leaks in
H5Tconv.c.
Platforms tested: h5committest

Code optimization & bug fix
Description:
When dimension information is being stored in the storage layout message
on disk, it is stored as 32-bit quantities, possibly truncating the dimension
information, if a dimension is greater than 32-bits in size.
Solution:
Fix the storage layout message problem by revising file format to not store
dimension information, since it is already available in the dataspace.
Also revise the storage layout data structures to be more compartmentalized
for the information for contiguous, chunked and compact storage.

It cannot cast unsigned long long values to float or double values. So, add

Checkpoint checkin of FP bug fixes. FP is still quite
buggy, but I must go deal with other matters.
Description:
Fixed two major bugs:
1) H5FPserver.c was clobbering meta data in its care.
2) H5FPserver.c was allocating the same space multiple
times, causing both data and meta data corruption.
Also made minor fixes, added debugging code, and familiarized
myself with the FP code.
All development work with FP enabled was done on Eirene.
On this platform, FP now passes its test reliably with
up to 9 processes. At 10 processes it seg faults every
time. I haven't looked into this issue.
There are also several known locking bugs which have to
be fixed. However, they are of sufficiently low probability
that I didn't bother with them on this pass.
FP has not been tested with deletions -- this should be
done.
Also, need to test FP chunked I/O.
Solution:
1) Modified cache in H5FPserver.c to merge changes correctly.
Found and fixed a bug in H5TB.c in passing.
2) Multiple space allocation was caused by a race condition
with set eoa requests.
Most of these eoa requests appeared to be superfluous, so
I deleted them.
Those issued during the superblock read seemed necessary,
so I inserted a barrier at the end of the superblock read,
to prevent races with allocations.
Platforms tested:

Description:
Fixed bug in H5TB_less(). It was returning the next largest node,

Platforms tested: h5committest
Code optimization
Description:
Eliminate memory allocations for I/O vectors when using the default
vector size.
Platforms tested:
Solaris 2.7 (arabica)
FreeBSD 4.9 (sleipnir)
too minor to require h5committest
Code optimization
Description:
Remove another dataspace copy, in certain circumstances.
Platforms tested:

Code optimization
Description:
Remove a memcpy() from a commonly called routine and replace a multiplication
with a series of additions.
Platforms tested:

Code optimization
Description:
Avoid another extraneous dataspace copy.
Platforms tested:
Solaris 2.7 (arabica)
FreeBSD 4.9 (sleipnir) w/parallel
too minor to require h5committest
Code optimization
Description:
Change algorithm to directly use coordinates describing a chunk's position
in a dataspace instead of creating a dataspace with the chunk's position
selected. This reduces the number of copies of dataspaces we need to keep
around.
Platforms tested:
Solaris 2.7 (arabica)
FreeBSD 4.9 (sleipnir) w/parallel
too minor to require h5committest
Description: Mainly are header message changes for dataspace. In last round
of check-in, a new header message for dataspace to created, which is not a good
way. Now, there will be no new message for dataspace, but just add the type of
dataspace in the message while increment its version number. Backward compatibility
is addressed. The attribute design is modified accordingly.
Platforms tested: h5committest
Code optimization
Description:
Check for only performing I/O on a single chunk and re-use memory dataspace,
instead of re-creating the same dataspace & selection the hard way.
Platforms tested:
Solaris 2.7 (arabica)
FreeBSD 4.9 (sleipnir) w/parallel
too minor to require h5committest
Code optimization
Description:
Eliminate more dataspace copying, etc.
Platforms tested:
Solaris 2.7 (arabica)
FreeBSD 4.9 (sleipnir) w/parallel
too minor to require h5committest
Code optimization
Description:
Reduce the number of dataspace copies made when performing I/O on chunked
datasets.
Platforms tested:
Solaris 2.7 (arabica)
too minor to require h5committest
Description: NULL dataspace. This step is mainly for dataspace header
message and a test.
Solution: The test mainly checks NULL dataspace features. Backward compatibility
is tested in the fill value test.
Platforms tested: h5committest
Code optimization
Description:
Eliminate unnecessary allocation and point at existing data structure
instead.
Platforms tested:
Solaris 2.7 (arabica)
too minor to require h5committest
Code optimization
Description:
Fix H5S_select_hyperslab to use arrays on the stack instead of dynamically
allocating them each time.
Platforms tested:
Solaris 2.7 (arabica)
too small to require h5committest
Code optimization
Description:
Fix H5S_select_copy so it doesn't call calloc() for allocating memory that
will be immediately overwritten.
Platforms tested:
Solaris 2.7 (arabica)
too small to require h5committest
Code optimization
Description:
Minor tweaks on the optimized offset/length sequence generator to improve
performance by reducing the number of 64-bit multiplies and calls to memcpy().
Platforms tested:
Solaris 2.7 (arabica)
too minor to require h5committest
Code optimization
Description:
Compute the size of a chunk once, when the layout information is set,
instead of each time I/O is performed on the chunk.
Platforms tested:
h5committest
Solaris 2.7 (arabica)
Code optimization
Description:
Move handling for free list arrays that have no maximum size to separate
set of routines and optimize computations for free list arrays with maximum
size to avoid re-computing sizes all the time.
Platforms tested:
h5committest
Solaris 2.7 (arabica)
Bug fix/code cleanup
Description:
Copy Robb's feature in SSlib that checks that the name of the function
used in the FUNC_ENTER macro is actually the name of function.
Fixed a bunch of typos & copy-n-pasto's for functions with incorrect names.
Platforms tested:
FreeBSD 4.9 (sleipnir) w/parallel
too minor to require h5committest
bug fix.
Description:
H5FD_mpio_init was calling the public API version of H5Iget_type()
which would clear the error stack, thus cleared away error messages
prematurely.
Solution:
Changed it to call the private version of H5I_get_type() which
does not clear the error stack.
Platforms tested:
o2 (SGI) parallel.
Description: The algorithm of H5T_bit_neg wasn't general enough.
Solution: Changed it to handle arbitory starting position and size
in a bit sequence.
Platforms tested: h5committest.
Description: The H5T_bit_dec algorithm wasn't general enough.
Solution: Changed it to handle bit sequence starting at any position
and of any length.
Platforms tested: h5committest
