[svn-r8892] Purpose: Code cleanupDescription:
Clean up a bunch of warnings and bring new code better inline with current
library coding practice.
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel
Too minor to require h5committest
Misc. update:
[svn-r8889] Purpose: Update.Description:
Due to source code change, added 2 new projects to the Windows tests and
removed some files from a Windows project. Updated h5repack testing batch file
in Windows. Did some minor updates for cache project.
Solution:
1. Added 2 new projects reserved and reserveddll to the Windows workspace. These two projects include
the new source code reserved.c.
2. testh5repack_filters.c and ...
[svn-r8886] Purpose: bug fix.Description:
The previous patch of -D__GNUC__ was causing failure in the
newer compiler. The previous failure could not be repeated
any more. So, removed it.
Platforms tested:
Tested only in TG-NCSA since the change affects only the ia64 platform.
Misc. update:
[svn-r8884] Purpose: Bug fixDescription:
It uses the value of $ARCH as a gcc option but the linux clusters
at NCSA define $ARCH as environment variable with values that are
not a valid compiler option. That caused the configure to fail
because it was not able to compile at all.
Solution:
Change ARCH to lower case $arch (convention dictates environment
variables are upper cases.) Also preset $arch to null and do not
hon...
[svn-r8882] Purpose: bug fix, new featureDescription:
fixed bug in the parse function:
cases where we have an already inserted name but there is a new name also
example:
-f dset1:GZIP=1 -l dset1,dset2:CHUNK=20x20
dset1 is already inserted, but dset2 must also be (it was not)
added a CHECK_SZIP symbol to enable/disable checking of library related szip parameters
added the print of the filter name in verbose mode (confirms vis...
[svn-r8881] Purpose: Bug fixDescription:
Replaced "unsigned long long" with hsize_t in H5MF
Added "return 0" at end of reserved.c test
Platforms tested:
arabica, sleipnir
[svn-r8879] Purpose: New featureDescription: New API H5Tencode and H5Tdecode. Given object ID, H5Tencode encodes object information into a binary form. H5Tdecode decode an object information in a binary form, reconstructs the object and return a new object ID.
Solution: Use object header functions H5O_dtype_decode and H5O_dtype_encode to
facilitate them. The encoded binary is exactly like object header information.
This...
[svn-r8877] Purpose: Bug FixDescription:
If an HDF5 file grows larger than its address space, it dies and is unable to
write any data. This is more likely to happen since users are able to change
the number of bytes used to store addresses in the file.
Solution:
HDF5 now throws an error instead of dying. In addition, it "reserves" address
space for the local heap and for object headers (which do not allocate space
imme...
[svn-r8874] Purpose: Bug fixDescription:
Correct problems with "resurrecting" a dataset in a file. (This occurs
when a dataset which is open gets unlinked from the group hierarchy (making it
"dead" and marked for deletion in the file) and then is re-linked to the group
hierarchy). Note that the current solution applies only to datasets, further
work will fix this for groups and named datatypes also.
Also, fix th...
[svn-r8869] Purpose: h5repack changesDescription:
there were some requests to change some minor h5repack features
h5repack only made a warning about a non available filter in verbose mode ( -v )
without -v it kept silent, and users sometimes missed this warning
the request was that it should print this warning always. so, the new format, is e.g
./h5repack -i test_szip.h5 -o out.h5
Warning: dataset </dset_szip> cannot be read, SZ...
[svn-r8867] Purpose: Bug fixDescription:
Fix error in chunked dataset I/O where data written out wasn't read
correctly from a chunked, extendible dataset after the dataset was extended.
Also, fix parallel I/O tests to gather error results from all processes,
in order to detect errors that only occur on one process.
Solution:
Bypass chunk cache for reads as well as writes, if parallel I/O driver is
used and f...
[svn-r8865] Purpose: Code optimizationDescription:
Re-work the insertion of a new child into an existing node, to exploit
some speedups for adding the rightmost child, since this is a very common case
when appending records to an unlimited size dataset.
Also, hoist the checks for the tree's 'K' value into a field in the shared
information about the tree, instead of re-calculating them all the time.
Platforms tested:
S...
[svn-r8860] Purpose: Code optimizationDescription:

Platforms tested:
MS Visual C++ 6.0 on Windows 2000.
(will test on Windows XP with Visual C++ 6.0 and .NET after this check-in)
Misc. update:
[svn-r8853] Purpose: Code optimizationDescription:
Refactor B-tree code to extract all common information for a B-tree into a
shared structure that is pointed to by all the nodes in tree (instead of being
included in each node).
Also re-order B-tree node comparison checks for chunked datasets to
check for >= the upper node first, since the comparison is a bit "heavy" and
this check is more likely to succeed when you are ad...

Solution:
Platforms tested:

too minor to require h5committest
[svn-r8844] Purpose: Bug fixDescription:
The "shared" raw B-tree node can get freed before all the B-tree nodes
had been flushed out to disk and released by the cache.
Solution:
Implement a simple reference counting wrapper for objects in the library
and use it to hold the shared raw B-tree nodes so they aren't freed before all
references to them in memory are released.
Platforms tested:

compound, with char data)
Solution:

linux

Misc. update:
[svn-r8823] Purpose: Code optimizationDescription:
Since the raw B-tree nodes are the same size and only used when reading in
or writing out a B-tree node, move raw B-tree node buffer from being per node
to a single node that is shared among all B-tree nodes of a particular tree,
freeing up a lot of space and eliminating lots of memory copies, etc.

[svn-r8822] Purpose: Update Makefile.inDescription:
Removed macro H5_FILES from Makefile.in so that output files from the
example programs will not be installed.
Platforms tested:
Linux 2.4 (eirene)
SunOS 5.7 (arabica)
[svn-r8818] Purpose: Potential bug fixDescription: In H5Fget_filesize, file size was returned as haddr_t. Change it to hsize_t
and return it as parameter to make fortran interface easier.
Platforms tested: fuss(simple change).
[svn-r8817] Purpose: Bug Fix.Description:
nh5zget_filter_info_c function was not declcared as H5_FCDLL, which is
required for fortran dll in Windows. _H5ZGET_FILTER_INFO_C is considered
as an unresolved external symbol by Fortran Compiler in Windows without
H5_FCDLL.
Solution:
Added H5_FCDLL for nh5zget_filter_info_c function.
Platforms tested:
DEC Fortran 6.0 in Windows XP.
Misc. update:
[svn-r8816] Purpose: Remove filesDescription:
