[svn-r9584] Purpose: Code optimizationDescription:
Revise mechanism for calling H5open/H5check to better avoid calling them
from internal libray code.
Only copy a datatype's group entry information if it has some.
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel
Solaris 2.7 (arabica)
Too minor to require h5committest
[svn-r9580] Purpose: Add new internal data structureDescription:
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...
[svn-r9579] Purpose: bug fixDescription:
one header file that was removed from the repo was not removed from the makefile.in,
causing make install to fail
Solution:
removed the file from the public header file list to be installed
Platforms tested:
linux
Misc. update:
[svn-r9572] Purpose: bug fixDescription:
the routine for applying the layout for the new file of h5repack was not
handling the logic correctly in cases where an input layout was not set
Solution:
changed the logic so that the original layout is preserved

[svn-r9567] Purpose: Cleanup & add testDescription:
Clean up test makefile a bit and add metadata cache test to 1.6 branch.
Platforms tested:
FreeBSD 4.10 (sleipnir)
Too minor to require h5committest
[svn-r9565] Purpose: 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.
[svn-r9563] Purpose: Code optimizationDescription:
Change how default allocation time is handled internally to the library,
to avoid some performance issues with property lists.

the Makefile.in of the hl tests was not including a "srcdir" include path
the test table .c file was missing also the srcdir path
Solution:
add it

[svn-r9559] Purpose: Code optimizationDescription:
Switch a few more malloc/free pairs over to using internal free list code,
to avoid abusing system memory allocator as badly.

[svn-r9556] Purpose: Code cleanup & optimizationDescription:
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 r...
[svn-r9555] Purpose: Fixing minor bugDescription:
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:
[svn-r9552] Purpose: Code optimizationDescription:
Avoid making as many copies of attribute information.
Also, be smarter about which properties we've seen before when copying
and closing property lists.
Fix memory leak of attribute data structures.

[svn-r9543] Purpose: Bug fix (#264)Description:
h5dump did not print attribute data in ASCII format when
-r is used.
Solution:
Added the ability to print in ASCII for Attributes Data also.
Added a test for printing Attributes with -r option.
tall-2B.ddl is the standard output for printing attributes with -r option.
Platforms tested:
H5committested.
Also in heping.
Misc. update:
Update MANIFEST.

[svn-r9539] 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 ...
[svn-r9537] Purpose: Code cleanup & optimizationsDescription:
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 a...
[svn-r9533] Purpose: enhanced performance for h5diffDescription:
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:

Misc. update:
[svn-r9531] Purpose: Bug fix(#213)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'...
[svn-r9530] Purpose: 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:

Misc. update:
[svn-r9529] Purpose: Check in some new fixes for MPI derived datatype routinesDescription:
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.

[svn-r9526] Purpose: 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
[svn-r9524] Purpose: Bug FixDescription:
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:
[svn-r9523] Purpose: Added data transform exampleDescription:
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
Platforms tested:
eirene + copper

Note: These codes have not been tested for general use.
Don't call these functions in your developments of the HDF5 library.
Also these codes are stand-alone codes, they should not affect
other library codes.

[svn-r9515] Purpose: Bug fixDescription: For Intel 8.1 compiler, C99 standard has to be enabled to define macro ULLONG_MAX in its own header file limits.h.
