Solution: It looks like that two extra blank lines after
CPPGLAGS definition caused the syntax error
I deleted the lines, and compilation went through

Bug fix
Description:
Correct integer overflow situation for computing the size of a dataset.
Solution:
Rachet one of the dimensions down far enough that the total size of the
dataset's raw data doesn't overflow a 64-bit int.

Platforms tested:

New internal feature
Description:
Add a "release" routine to the skip lists, which releases all the nodes
in the skip list, but keeps the skip list active.

Code optimization
Description:
Retarget metadata cache code from using TBBT routines to using new skiplist
routines, for a reasonable speedup (when dealing with dirty metadata)

Bug fix
Description:
Re-work array of 'forward' pointers in a way that makes the PGI compiler
more happy.
Solution:
Change from 'H5SL_node_t *forward[1]' to 'H5SL_node_t **forward' and
change how array of forward pointers is dealt with.

Description:
Add dependency on the HDF5 library as well as the high-level library for
rebuilding tests.

Bug fix
Description:
Correct off-by-on error which could cause invalid # of levels to be used
for a skip list node, in rare circumstances.
Change from srandom()/random() to more portable srand()/rand() routines
for random # generation.
Pre-compute the probability factor for computing the level of new nodes,
for a minor speedup.

Code optimization
Description:
Begin de-orbital burn of threaded, balanced binary tree code use by
switching file open object code over to using them. Initial benchmarks show
that skip lists are 5-10x faster than our TBBT code...

Description:
Revise mechanism for calling H5open/H5check to better avoid calling them
from internal libray code.

Add new internal data structure
Description:
Add an implementation of skip lists to the library (see comment in
src/H5SL.c for references to the papers describing them) as a potential
replacement for our current threaded, balanced binary tree container.
Skip lists are much simpler to implement and should be faster to use.
Also, added new error codes to release branch, so bump the minor version
number to indicate that the library is no longer perfectly compatible with
the 1.6.3 release.
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel
Solaris 2.7 (arabica)
Too minor to require further testing (the skip lists aren't actually
used by any library code yet)
bug fix
Description:
one header file that was removed from the repo was not removed from the makefile.in,
causing make install to fail
Solution:

Misc. update:
bug fix
Description:
the routine for applying the layout for the new file of h5repack was not

Solution:

Improvement.
Description:
Change the default CC, F9X and CXX compilers from ecc/efc/ecc
to icc/ifort/icc because Intel keeps changing their compiler
names. This eliminated the warning messages that a wrong
compiler name is used.
Platforms tested:
Tested in Tg-login NCSA only since that is the only
IA64 platform on site.

Code cleanup & optimization
Description:
Improve ADF/CGNS benchmark by reducing the number of internal attribute
copies made during creations, opens and writes.
Added new H5O_iterate() routine for iterating through messages of a certain
type in the object header (attributes are the only message currently that can
have multiple instances in the object header).
Cross-pollinated various minor code cleanups to reduce diffs between
branches.

Xuan reported that "uint" used in this example caused error when
built with MS Visual Studio compiler.
Solution:
Changed to "int."
Platforms tested:
Very minor, so I only tested on eirene. I'll let Xuan know
to check on Windows.
Misc. update:

h5dump did not print attribute data in ASCII format when

Purpose: Correction to previous bug fix. This checkin is mainly to let user
test his program.
Description: For family driver bug(#213), the previous fix was imperfect. The problem
was when user create family file, the member size information wasn't saved in file. When
the file was re-opened, the library simply use the size of 1st member file as member size.
Solution:
When file is re-opened, member size passed in from access property
is checked to see if it's reasonable. If there is only 1 member
file, member size can't be smaller than current member size.
If there are at least 2 member files, member size can only be equal
to the 1st member size.
Platforms tested: h5committest and fuss
Code cleanup & optimizations
Description:
Clean up some of the code in attributes to avoid allocating memory and
performing type conversions when the conversion is a noop.
Avoid memory allocations of attribute data structures by switching to use
library's free list memory allocator routines.
Avoid memory allocations of object header continuation data structures by
switching to use library's free list memory allocator routines.
Rearrange threaded, balanced binary tree macros slightly to avoid some
overhead.

enhanced performance for h5diff
Description:
the comparison cycle for the 2 buffers read from file was using a compare function
where the type must be checked for each datum (e.g due to recursive calls in compound types)
for atomic types this checking can be avoided
Solution:
introduced cycles for each one of the atomic integer and float class types
Platforms tested:
linux
aix
solaris
Misc. update:
Description: H5Pset_fapl_family sets family member size only for creating
new file. The file doesn't keep this size information. When the file is
re-opened, the size of first member file is used as the member size.
Solution: Assume user knows the original member size and sets it through
H5Pset_fapl_family. That will be the member size. User can pass in value 0
as member size if he doesn't know the original member size. Library will
choose the size of current first member size as the member file size.
Platforms tested: h5committest and fuss.
Modifying testing code for derived datatype.
However, this test won't be run in the HDF5 parallel test.
The code is checked in only for debugging purpose.
Description:
Solution:
Platforms tested:
Linux 2.4(mpich 1.2.6)
Misc. update:
Check in some new fixes for MPI derived datatype routines
Description:
MPI derived datatype algorithm seems working for a simple case;
however, there are still other problems need to be solved. So the
code cannot be used for the time being. Check-in only for debugging.
It won't affect other part of the library.
Solution:
Platforms tested:
Linux 2.4 (heping, serial and parallel)
(Since no new tests were added and changes are mostly restricted to
one fuction, no need to test three platforms).
Misc. update:
Bug fix, sorta.
Description:
Revert change to H5Pget_data_transform() which changed len of buffer
returned to be inconsistent with H5Iget_name(), etc. We should discuss this
change and apply it to all the similar functions if we decide to change the
return value.
Platforms tested:
FreeBSD 4.10 (sleipnir)
Too minor to require h5committest
Bug Fix
Description:
Fixed off by one error in H5Pget_data_transform
Solution:
H5Pget_data_transform, when queried for the size of the property, should
return strlen() + 1 so that the user can allocate memory for the terminating
\0 in the string.
Also fixed a typo in a comment in H5Ztrans.c
Platforms tested:
eirene, too minor to require further testing.
Misc. update:
Added data transform example
Description:
Added example code for the data dtransform
Solution:
This code both illustrates how data transform works and shows how to use it.
Examples of data transform on read, write, and both at the same time.
Also shows usage of H5Pget_data_transform

eirene + copper
