Feature shift
Description:
Take out the v1.2.x compatibility stubs and put in the hooks for v1.4.x
compatibility when needed.
Platforms tested:
FreeBSD 4.3 (hawkwind)
Purpose:
Bug Fix
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
anything and cause problems since it would then overwrite the
beginning of the header file's path.
Solution:
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
compiler...
Platforms tested:
Linux
Purpose:
Bug Fix/Feature Add
Description:
Added new flag ("-f" and "--family") to allow user to specify which
file driver to use to open the file. If they don't specify anything,
then it defaults to the old behaviour of trying each driver in turn
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.
Platforms tested:
Linux
Purpose:
Reformatting
Description:
Reformatted the code so that it's much clearer and conforms to the
HDF5 coding standards. Changed the function headers to use the ANSI
style instead of the KnR style. Kept the use of typedef's such as
"unsigned char" being "BYTE" and so on since of of this code is
copied from some other place and that's the style they use...I didn't
want to break things.
Platforms tested:
It compiles fine on Linux, but there aren't any tests for this
package, so...
Purpose:
Fixing a boo-boo
Description:
There was a problem with the generated Dependencies file. It listed
the H5pubconf.h header file as being in the $(top_srcdir) directory
when it's in the $(top_builddir) directory.
Solution:
Regenerated it.
Platforms tested:
Linux
Purpose:
a bug in the comment
Description:
The structure of HDF4 file is not correct in the orginal comment
Solution:
Correct the wrong comment and add more explanation
Platforms tested:

Bug Fix, Code Cleanup, Code Optimization, etc.
Description:
Fold in the hyperslab speedups, clean up compile warnings and change a
few things from using 'unsigned' or 'hsize_t' to use 'size_t' instead.
Platforms tested:
FreeBSD 4.3 (hawkwind), Solaris 2.7 (arabica), Irix64 6.5 (modi4)
Purpose:
Bug fix (by Bob McGrath)
Description:
On Solaris platforms palette was not written to the HDF5 file
Solution:
'\0' character was written outside the GroupName array. Apparently on Solaris it destroyed the condition value that determined if the palette should be written to the file.
Platforms tested:
Not tested yet.
Purpose:
Bug fix
Description:
One of the function calls (H5Sget_simple_extent_dims) used parameter with
the wrong type. That caused compilation errors on T3E.
Solution:
Used NULL since that argument is optional and was never used.
Platforms tested:
T3E(mcurie) and IRIX64 (modi4)
code warrior support
and some clean up
the macros file_seek and file_offset_t that were repeated over sevral files were put only in
H5private.h
H5private .h was updated for win32

Description:
Solution:
Platforms tested:
Purpose:
new features
Description:
1. add an option to convert HDF4 file without HDF4 specified attributes such as
HDF4_OBJECT_TYPE, HDF4_REF_NUM etc.
it can be done by inputting "h4toh5 -na input.hdf"
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.
Solution:
Platforms tested:
eirene(Red Hat 6.2) and arabica(solaris 2.7)
Purpose:
update h4toh5 converter utility test files
Description:
better output of HDF4 dimensional name list
Solution:
Platforms tested:
eirene,arabica
Purpose:
update h4toh5 testing files
Description:
Now we are using fixed size for HDF5 dimensional name list and h5dump
output is appended with 000/000/.......................
It looks ugly and annoying.
Solution:
Use NULLTERM for SDS dimensional list names
Platforms tested:
RedHat 6.2(eirene) and solaris 2.7(arabica)
Purpose:
Bug fix
Description:
Rushabh added new directory tools/gifconv to CVS. He also modified
MANIFEST, but bin/chkmanifest complains this file.
Solution:
I will try to delete gif.h and then to add it once more.
Purpose:
Adding new feature
Description:
Added gif2h5 and h52gif conversion utilities
Solution:
The utilites follow the framework built for the gif2hdf and hdf2gif
utilities for hdf4. The main files modified were those that read the
H5 file and those that write H5 file. In the future, if you wish to
continue with the framework and extend it to .png or some other fileformat
the main files to edit will be the gif reader and writer.
One point to note with h52gif. You have to specify the exact location of
the image and the palette that it links to. You can choose not to specify
a palette (uniform grayscale chosen in this case) but you must specify
image location. In the future, someone could edit the readhdf.c source
to enable the reader to parse the hdf file and select all images with
corresponding palettes.

Purpose:
a bug fix
Description:
User can define "Real Vdata" as user-defined attribute. By using VSisattr, we can check this out. In order to keep this piece of information, We use "Vdata attribute" in the converted HDF5 file to distingush this kind of Vdata from independent Vdata.
Solution:
see above
Platforms tested:
eirene(Linux)
Purpose:
a bug fix
Description:
When Vsisattr is true, this Vdata still needs to be converted as an independent
real "Vdata", We will add object type of this vdata as "Vdata attribute".
Solution:
erease the evaluation of Vsisattr call.
Platforms tested:
Linux(eirene)
Purpose:
bug fix Adding more features
Description:
Bugs: 1) hdf4 dimensional scale data can be none, but the dim name can still defined by users, so number of hdf4 dimensional names and number of object reference may be different
Previously, this problem is not considered.
2) SDcheckempty will return true when fill value is set to HDF4 SDS, and then fill value information is lost
3) check whether SDS have fill value set although SDcheckempty return true.
Use H5Psetfillvalue and H5Dcreate in HDF5 part, still needs to wait for the new development of HDF5 and also need to investigate whether this part of code has bugs.
New features: compressed SDS will get compressed with gzip when it is converted. That will save some space.

small bug fix
Description:
If specifying --stride, it was checking for the wrong short-form of
the command-line parameters.
Solution:
Changed the 'T' to 'S' which is the new short form for the stride
option.
Platforms tested:
Linux
Update
Description:
If the count for a subset isn't specified, then we default to the
remainder of the dataset.
Solution:
Check for the count to be specified. If not, then find the dimensions
of the dataset and subtract from the the "start" parameter.
Platforms tested:
Linux
Update
Description:
Updated the way the subsetting data is retrieved. It now does it one
row of blocks at a time. It may still run out of memory, but this is
at least a good first step.
Also, the start parameter defaults to (0, 0, ...) if it isn't
specified.
Platforms tested:
Linux
Update
Description:
Replaced
#include <hdf5_file.h>
with
#include "hdf5_file.h"
so that gcc can pick up our files more easily without picking up
system header files (which we don't care about being in the
dependencies list).
Platforms tested:
Linux
Update
Description:
Replaced "#include <hdf5_file.h>" with the equivalent, but better
#include "hdf5_file.h" so that gcc can pick up our header files more
easily.

Purpose:
a bug fix
Description:
when creating sds dimensional scale dataset, I accidently created two sds dimensional scale dataset with the same name, (say using name "dim1" for both rank 2 and rank 3).
hdf4 library doesn't give me complaints, hdp dumpsds doesn't generate complaints. h4toh5 converter since assumed that dimensional scale name has to be unique, simply skip if finding the same dimensional name, so accidently the result from hdp dumpsds are the same as the result from h5dump until I implement library API and find this bug.
Solution:
make unique sds dimensional scale name for this test file. Will also need to modify testfiles later.
suggestions: somebody check hdf4 library to disallow the same dimensional scale nameOused for the same sds object.
Platforms tested:
eirene, and this check in will not affect daily test.
Update
Description:
Applied fix to h5dumper which was applied to the 1.4 branch. Done
just before creating subdirectories in the 1.4 branch.
Platforms tested:
Linux
Updated
Description:
Updated test results for the h5dumper's XML option. The tool now
conforms with the fixes implemented in the 1.4 branch.
Platforms tested:
Linux
Feature Add
Description:
This is the first (alpha) version of h5tools which does subsetting
according to the subsetting document. There's still some niceties
which need to be worked out, but this is the ground work.

Bug Fix.
Description:
Kent is correct about the malloc error. It's harmless if it's not
needed anyway.
Solution:
Removed the #ifdef's since all platforms should use this.
Platforms tested:
Linux
Purpose:
fixing the format of dumper output for windows test
Description:
New dumptest includes the feature that an error of the output will be put into stderr in linux
On windows, that stderr will not be redirected into the output file and the comparsion between the expected file and the dumper output is not correct.
Solution:
change fprintf(stderr .....) at h5tool_util.c into fprintf(stdout ......) so that it fits the comparison.
Platforms tested:
windows 2000
Purpose:
a bug fix on windows(possible on other platforms)
Description:
not allocating enough space for a string at dump_all for debug version
a string tmp is defined at dump_all(....),
The memory that is allocated to tmp is malloc(strlen(prefix)+strlen(name)+1);
However, there is one testing case : strlen(prefix) is 0 and
tmp is allocated in the following:
strcat(tmp,"/");
strcat(tmp,name);
....
free(tmp);
the program fails when freeing tmp for debug (dll) version on windows 2000
Solution:
For windows platform:
allocate memory strlen(prefix)+strlen(name)+2
