Purpose:
Maintenancece.
Description:
F90 APIs would not compile anymore for || version..
Solution:
Replaced old functions h5pset(get)_mpio, h5set(get)_xfer with
ones h5pset(get)_fapl_m and h5pset(get)_dxpl_mpio_f
Platforms tested:
O2K.
Bug Fix
Description:
People need to type in the full-path to the
attribute/dataset/etc. and weren't being told to do so by the
"usage" statement.
Solution:
Added an example and changed <names> to <path> to be more
explicit...
Feature
Description:
Allow dumping of variable length records. This is a first-time
stab at this. It doesn't break any tests on my Linux box and it
does output the variable length data, but it might look ugly (it
doesn't handle new-lines as of yet)...I'm open to suggestions on
what should be done next, what new features to add/remove...
Platforms tested:
Linux
Code optimization
Description:
Minor tweaks throughout the optimized regular hyperslab code to increase
speed. This set of improvements increase the benchmark time from taking
~5.46 seconds to ~4.50 seconds, or around a 20% further speedup.
Platforms tested:
Solaris 2.6 (baldric)
Bug fix
Description:
Recent changes to H5FD_read() added a new argument of type of
data to be written but the MPIO file driver call to H5FD_read()
was not updated. Also, the prototype of H5FD_read() in H5Fprivate.h
was "screened out", thus the compiler could not detect the inconsistency.
With the mismatched arguments, MPIO failed badly.
Solution:
Update the H5FD_read() call with the new parameter. Since the
call is used by H5Dread call so far, it is hardcoded to use
H5FD_MEM_DRAW as the value. If the call is used besides for
H5Dread, this parameter needs to be better defined.
(Still need to fix the prototype being blocked off.)
Platforms tested:
O2K -64 parallel.
New tests
Description:
Added a new test file (tsaf.h5) for h5dump and h5ls. The test file was
created by lib SAF team. This file used to cause previous version
of hdf5 tools to core dump.
tsaf.ddl is the expected output from h5dump.
Platforms tested:

Platforms tested:
IRIX64 -64, linux
Purpose:
Bug fix.
Description:
fortranlib_test.f90 had a typo in the format string. Would not compile on O2K.
Test did not check the length of the attribute name.
Solution:
Fixed format strings.
Added more code to test returned attribute name length.
Platforms tested:
O2K, Linux
Purpose:
Bug fix
Description:
Attribute test failed on O2K. h5aget_name_f function could not
return correct attribute name.
Solution:
size function parameter had wrong datatype in F90 subroutine.
Fixed it to be of INTEGER(SIZE_T) type.
Platforms tested:
O2K, Linux
Bug Fix
Description:
Getting messages while compiling the || fortran stuff that it
didn't have a rule to make "H5Pf_parallel.c".
Solution:
The quotes were confusing it. I placed the text in another macro
to fix this.
Platforms tested:
Modi4
Purpose:
This file describes the experiencing of OpenMP with hdf5.
Description:
All detailed description is in the file.
Solution:
[details about the changes, algorithm, etc...]
[Please as detail as you can since your own explanation is
better than others guessing it from the code.]
Platforms tested:
Everything was done on modi4.
Bug fix.
Description:
Could not find the pre-created file for the H5S_MAX_RANK test
when --srcdir option is used. testhdf5 was looking for it
in the currect directory only.
Solution:
Make use of the value of the environment variable srcdir that
is passed to the tests. Compose the real location of the testfile
in order to open it even from a remote build directory.
Platforms tested:
Modi4, arabica, eirene
new feature
Description:
h5ls was not tested
Solution:
Added a test script, testh5ls.sh, to give h5ls some tests.
Since the output from h5ls is sometime machine dependent (e.g.,
Datatypes), can not compare them with expected output. For now,
run it against various hdf5 binary files. If it exits with 0,
consider it passes.
Platforms tested:
IRIX64, eirene, arabica.
tidy it up
Description:
Change the variable names so that it looks more generic. Plan to
make it a generic script test template.
Platforms tested:
IRIX64-64, linux, solaris 2.7
Feature symmetry
Description:
A while ago I needed to get the 'type' of data being accessed during writes
to the VFL driver, so I put in code to get the information down there.
Albert asked for the same information during reads, so I've added that in.

Description:
During a `reconfigure', it wasn't traversing the
subdirectories...
Solution:
Added a loop to the reconfigure logic to do just that.
Platforms tested:

Change test files for increased maximum dimension constant.
Description:
space_overflow.c - added some simple error checking.
th5s.c - corrected test case for maximem dimensions to use correct file
and actually test what is supposed to be tested... :-)
th5s.h5 - regenerated with increased dimensions.
Platforms Tested:

Solaris 2.5 (baldric)
Increase constant for H5S_MAX_RANK from 31 -> 32
Description:
To better align the HDF5 library's maximum dimenions with HDF4 and netCDF,
the maximum number of dimensions has been increased to 32.
Platforms Tested:
FreeBSD 4.1.1 (hawkwind)
Solaris 2.5 (baldric)
Purpose:
Added more Fortran tests
Description:
tH5A.f90 - attribute interface test
tH5I.f90 - identifier interface test
Solution:
Two new files were added to test H5A and H5I interfaces.
Platforms tested:
Solaris 2.7, Linux
Purpose:
H5Aff.f90: Bug fix
Description:
Character string was not passed correctly from the user's application
to the write/read subroutines when buffer was decalred as assumed-shape
array.
Solution:
Declared date buffer to be assumed-size array.
Platforms tested:
Solaris 2.7, Linux
Purpose:
H5fortran_flags.f90: Bug fix
Description:
Fortran H5I_* types had incorrect values.
Solution:
Fixed.
Platforms tested:
Solaris 2.7, Linux
Bug fix.
Description:
When the maximum number of elements in a fixed size, free-list managed array
was allocated, the free-list code was writing off the end of the array.
Solution:
Changed definition of free-list managed arrays to allocate correct space for
the array.
Platforms tested:
Solaris 2.5 (baldric) w/Purify
Features, kind of.
Description:
Separated the MPI features test into its own independent
program so that it can be tested on its own without too
much HDF5 stuff involved.
Added automatic removal of temporary test files after
the tests completed.
Reduced the size of the dataset dimensions to avoid tripping
the SGI MPI problems of running out of internal mpi type entries.
Platforms tested:
O2K -64
Optimization for parallel I/O
Description:
When contiugous hyperslabs are defined (i.e. with the block=stride), the
library was only aggregating the hyperslabs together for the fastest
changing dimension.
Solution:
Add some extra code to detect when contiguous hyperslabs span more than one
row and output the entire contiguous section at once.
Platforms tested:
FreeBSD 4.1.1 (hawkwind)
Bug Fix
Description:
the line:
#include <hdf5.h>
needed to be escaped to be seen in the browser.
Solution:
Changed to:
#include <hdf5.h>
Platforms tested:
Seen in Netscrape
Bug Fix
Description:
Sed was complaining about "filename expected" when trying to
generate the .in files. The problem stemmed from the script sed
was generating in the conftest.s1 file. It needed the DEPEND
filename which wasn't being set.
Solution:
Fixed so that we check if DEPEND is zero before trying to set if
(if not using a GNU make program) instead of testing if DEPEND
has a value in it...I copied this incorrectly from the main
library's configure.in file...my bad.
Platforms tested:

Adding new document links
Description:
Adding links to TechNotes/VFL.html and TechNotes/VFLfunc.html,
the new virtual file layer documents.
Platforms tested:
IE 5
Code cleanup
Description:
There's been a compiler warning about modifying a 'const' object in the
H5T_copy routine for several years now, which a few users have reported.
Solution:
Removed call to sort the old datatype (the const object) and changed the
code to work with unsorted datatypes.
Platforms tested:
FreeBSD 4.1.1 (hawkwind)
Bug fix
Description:
"Time" datatypes (H5T_UNIX_D*) were not being stored and retrieved in
the datatype object header message correctly.
Solution:
Store endian-ness and precision in the datatype object header message and
added test to continue to track them working correctly.
This fixes bug #512.
Platforms tested:
FreeBSD 4.1.1 (hawkwind)
Adding new document
Description:
Adding VFL.html (Virtual File Layer) to HDF5 Technical Notes.
August 1999 version. Will be updated for R1.4 by developer.
Platforms tested:
IE 5
Bug Fix
Description:
On some platforms, if you don't have . in your PATH, it won't
find the test program it's supposed to run.
Solution:
Changed instead to ./$$test so that it picks up the program in
the current directory.
Platforms tested:
Opus and Linux
Buglet Fix...kinda
Description:
The --enable-c++ flag is in there, but configure can't handle the
++ on the end.
Solution:
Changed it to --enable-cxx instead. N.B. This feature isn't
really needed yet since C++ isn't integrated with the library
proper.
Platforms tested:
Linux
Bug fix
Description:
H5Sget_simple_extent_npoints return type is hsize_t and the error value is
0, but it is possible to have 0 points in a dataset with an unlimited
dimension, but no data written yet.
Solution:
Changed H5Sget_simple_extent_npoints return type to hssize_t and the error
value to -1
Platforms tested:
FreeBSD 4.1.1 (hawkwind)
Bug fix (bug #446)
Description:
H5Tget_offset return type was size_t and the error return value was 0, but
0 is also a valid successful return value.
Solution:
Changed the return type to int and the error return value to -1
Platforms tested:
FreeBSD 4.1.1 (hawkwind)
Purpose:
1. fix multiple defination warnings at sgi platform
2. adding chunking information from hdf4 to hdf5 property list.
Description:
1. Orginally global varibles were defined at one header file and this
header file were included by other .c file and .h file so multiple warnings are
generated.
2. Chunking information was not included in the previous version.
Solution:
1. use "extern" to define global variables at h4toh5util.h file and define global variables
at h4toh5main.c
2. retrieve the chunking info from sdgetchunkinfo and GRgetchunkinfo and store these information
into hdf5 property list.

Bug fix.
Description:
Previously, it has been possible to dereference deleted objects in a file.
Obviously, this is incorrect and could cause all sorts of problems if the
object being dereferenced had been partially over-written with other
information. - This is documented in Bug #493.
Solution:
Check the link count for objects being dereferenced and don't allow any
objects with link counts of zero to be dereferenced.
This fixes bug #493.
