Document bug
Description:
Mention that h5dump and h5ls are not displaying variable-length string
datatype information correctly. I've also entered a more detailed bug into
the bug database.
Bug Fix.
Description:
The H5Rget_object_type function could not get the object type for dataset
region references.
Solution:
Added a new function, H5Rget_obj_type, to replace H5Rget_object_type.
The new function requires the reference type as an additional parameter,
in order to allow queries on different reference types to be performed
correctly.
Platforms tested:
FreeBSD 4.4. (sleipnir)
Code cleanup
Description:
Tweaked internal error handling macros to reduce the size of the library's
object code by about 10-20%.
Also cleaned up some compiler warnings...
Platforms tested:
FreeBSD 4.4 (sleipnir)
Bug Fix
Description:
The file metadata macros generate unaligned access warnings on the IA64
architecture.
Solution:
Got rid of bogus big-endian vs. little-endian differentiation when encoding
and decoding file metadata and use proper set of macros to prevent unaligned
access problems.
This fixes bug #672.
Platforms tested:
FreeBSD 4.4 (sleipnir)
Bug Fix
Description:
The code in H5Sselect_hyperslab_valid contained an fencepost error and is
allowing selections which overlap the extent by exactly one element in any
dimension to pass as valid instead of flagging the selection as invalid.
This bug only affects hyperslabs which have been OR'ed together, not the
selection from a single H5Sselect_hyperslab.
This fixes bug #550.
Solution:
Changed an '>' to an '>=' and added new regression test to check for error.
Platforms tested:
FreeBSD 4.4 (sleipnir)
Code cleanup
Description:
Property that H5P(g|s)et_hyper_cache uses is no longer in use inside the
library.
Solution:
Removed H5P(g|s)et_hyper_cache API functions, except when backward
compatibility is turned on. When backward compatibility is turned on,
the property is defined by the library, but unused internally.
Platforms tested:
FreeBSD 4.4 (sleipnir)
Document bug fix.
Description:
The internal B-tree code was dumping core with an assertion failure when
flushing data to the file if too many objects were put into the same B-tree
(forcing the root node to split, I think).
Solution:
Fixed the B-tree copy routine to copy the correct number of raw keys.
Platforms tested:
FreeBSD 4.4 (hawkwind), Solaris 2.6 (baldric)
Documentation
Description:
Mention improvements to I/O speed for non-regular hyperslabs.
Hold off mentioning new API calls until we've reached consensus on them.
Purpose:
add new information and delete old windows and h4toh5 information on release.txt.
Description:
1. add a note to mention release dll will work after installing service pack 5 of VS6.0.
2. delete the fixed bugs on windows(libc.lib warnings and h4toh5 image handlings)
Solution:
Platforms tested:
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
Platforms tested:
FreeBSD 4.4 (hawkwind)
Purpose:
Feature add
Description:
Changed the "make install" thingy to "make install-all" in the
quick-setup guide. Also, changed the version number of HDF5 in the
examples from 1.4.0 and 1.2.0 to 1.5.x
Purpose:
fix a bug
Description:
In precondition 3, winzip will unzip hdf5xxx.zip into the directory
hdf5xxx and users should rename hdf5xxx into hdf5 to correctly build
HDF5 library.
Solution:
correct the sentence in precondition 3.
Platforms tested:
windows 2000
New feature
Description:
Added perform programs to test the HDF5 library performance. Programs
are installed in directory perform/.
Platforms tested:
eirene
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)
document update
Description:
The information of setting SGI_ABI seemed to confuse some user.
Removed it since it is extra information in addition to the
preferred method of "CC=... ./configure".
Experienced user in IRIX64 would know that option.
Platforms tested:
Eyeballed.
Bug fix... (sorta)
Description:
Added --enable-linux-lfs configure flag to have better control over whether
the enable large file support on Linux machines. Also removed the
-malign-double flag for gcc since it can potentially cause errors which
are difficult to detect.
Platforms tested:
Linix 2.2 & 2.4 (eirene and dangermouse)
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)
