Purpose:
A new feature
Description:
While testing h4toh5 utility with real NASA files, we find an example that the data array(one SDS) is so big that it exceeds the physical memory of some machine(>128 MB) and the conversion failed. Before the smart hyperslab operation is out, I am dividing the whole SDS into smaller hyperslabs with each hyperslab propotational to the original SDS array dimensions. For example, a three dimension array with 1000*1000*1000 elements, I can divide them into eight 500*500*500 pieces. I can read and write each piece and remember their starting and ending points. In this way, the memory allocation failure can be avoided; however, it may not be the efficient way.
I've tested this feature using SDS without chunking. It works fine. However, when testing SDS with chunking, it is extremely slow. This happens to be a bug in HDF5 library now. Quincey may fix this later and give me a more efficient way to handle the problem. Currently all my testing files are with UNLIMITED dimensions, so in HDF5 the chunking feature will be required.
SO by default, this feature will not be turned on.
Solution:
see the above

Kludge
Description:
Since we're only about halfway through converting the internal use of
property lists from the "old way" to the generic property lists, we turned
off snapshots to avoid exposing lots of API changes to users, until the
APIs settled down.
Getting the snapshots rolling again seems to have become a priority, so
some changes are going to have to be made now that were going to be
postponed until we were completely finished with the conversion. This
requires that the old API functions be able to deal with both the old
and new property lists smoothly.
Solution:
Kludge together the property list code so that they can transparently handle
dealing with both the old and new property lists

Code cleanup for better compatibility with C++ compilers
Description:
C++ compilers are choking on our C code, for various reasons:
we used our UNUSED macro incorrectly when referring to pointer types
we used various C++ keywords as variables, etc.
we incremented enum's with the ++ operator.
Solution:
Changed variables, etc.to avoid C++ keywords (new, class, typename, typeid,
template)
Fixed usage of UNUSED macro from this:
char UNUSED *c
to this:
char * UNUSED c
Switched the enums from x++ to x=x+1

Purpose:
add a real raster-24 bit testing for interlace mode.
Description:
1. GR interfaces will never create an HDF4 file with interlace mode other than
pixel interleaved. DF24 interfaces can create HDF4 file with different interleaved.
There are inconsistent behaviors between GRreqimageil and GRreadimage, data read into the memory will not behave properly if a new interlace mode is asked.
2. Currently HDF5 image spec. supports pixel interleaved and plane interleaved.
We make a real image file to test whether the converter is doing the right thing.
Solution:
We use DF24 bit APIs to generate a real image file that can be tested by H5view.

Code cleanup (sorta)
Description:
When the first versions of the HDF5 library were designed, I remembered
vividly the difficulties of porting code from a 32-bit platform to a 16-bit
platform and asked that people use intn & uintn instead of int & unsigned
int, respectively. However, in hindsight, this was overkill and
unnecessary since we weren't going to be porting the HDF5 library to
16-bit architectures.
Currently, the extra uintn & intn typedefs are causing problems for users
who'd like to include both the HDF5 and HDF4 header files in one source
module (like Kent's h4toh5 library).
Solution:
Changed the uintn & intn's to unsigned and int's respectively.

Improvement
Description:
The stdout and stderr were both redirected to an output file. This
works fine in tradition sequential Unix machines. But in some
parallel systems (like mpi-jobs in IBM SP), the stderr is merged
with stdout alright but not in the exact order as expected. This
is not deterministic in parallel jobs. So, the test output are
all there but the ordering maynot be as expected.
Solution:
Redirect stderr to separated file and append it to the stdout
file after test-command is executed. Then compare it with
the expected output. This eliminate the assumption that
stdout and stderr must merged in "chronical orders".
The .ddl file are updated by moving all stderr text to the end of the
file.
Platforms tested:
eirene.

Purpose:
1) fix the implementation of image according to image specfication
2) fix two bugs of SDS implemention. the first one is
to handle the unlimited SDS with the first dimensional size set to 0.
the second one is to change the way how HDF5 dataset is written.
Description:
1) mapping 24-bit image to 3D arrays instead of 2D compound datatype.
2) previously forgot considering unlimited SDS with the size set to 0.
3) H5P_set_buffer seems not working well for a extremely small size.
Solution:
1) see above.
2) add a special case to deal with this.
3) don't use H5Pset_buffer.

New Features!
Description:
Start migrating the internal use of property lists in the library from the
older implementation to the new generic property lists.
Currently, only the dataset transfer property lists are migrated to the
new architecture, all the rest of the property list types are still using
the older architecture.
Also, the backward compatibility features are not implemented yet, so
applications which use dataset transfer properties may need to make the
following changes:
H5Pcreate(H5P_DATASET_XFER) -> H5Pcreate_list(H5P_DATASET_XFER_NEW)
and
H5Pclose(<a dataset transfer property list>) -> H5Pclose_list(id)
This still may have some bugs in it, especially with Fortran, but I should
be wrapping up those later today.

Description:
The way we were generating Dependencies and .depend files was broken.
If the $srcdir or other macros began with a ".", then it would match

Wrote a Perl script which can handle this type of weirdness better.
It's only used when the environment is a GNU one with a GCC

until one actually opens the file.
If the driver the user specified doesn't succeed in opening the
file, then we do NOT try other file drivers.

The default converter will still keep HDF4 specfied attributes.
2. Add compression features (gzip) for image too. Now the compressed HDF4 image
can be supported by using HDF5 gzip. Not sure whether tools can read it. Need to be tested.
3. Change SPACEPAD to NULLTERM for HDF4 dimensional name list. We can use variable length HDF5 string to represent these names, however currently H5dump and H5view cannot support variable length HDF5 string. converter will wait for other tools' update.
