Bug fix
Description:
Allow I/O on extendible chunked datasets with (currently) zero-sized
dimensions to proceed harmlessly instead of dumping core on an assertion.
Solution:
Removed assertion and added checks to avoid problem situation in H5TB_end
Platforms tested:
FreeBSD 4.10 (sleipnir) w/ & w/o parallel
Too minor to require h5committest
Bug fix
Description:
Always write fill values to chunks when initializing entire B-tree and
any filters are defined.
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel
Solaris 2.7 (arabica)
Too minor to require h5committest
Purpose: Maintenance on MAC OSX
Description: Added support for the Absoft Fortran compiler.
Solution:
Platforms tested: MAC OSX with xlf and f95 absoft compilers;
xlf is set to be the default compiler.
Misc. update:
Code cleanup, sorta
Description:
Added ifdef sections for "H5_USING_PURIFY" in various places in the code,
which are designed to reduce the spurious "uninitialized memory read" warnings
from purify which are actually OK. Note that this macro will have to be
turned on by adding it to the CFLAGS for the build - I didn't think it was
important enough to add a configure flag for.
Also, the changes in H5HG.c optimize the walks through the objects in a
heap to only look at the 'used' entries instead of all the 'allocated' entries.
Platforms tested:
Solaris 2.7 (arabica) w/purify
Not tested by h5committest
Code cleanup
Description:
Fixed reserved.c test to use h5_fileaccess/h5_fixname/h5_cleanup.
Updated RELEASE.txt for previous bug fix
Platforms tested:
sleipnir, verbena
Bug fix
Description:
Allow buffer parameter to H5Dread & H5Dwrite to be NULL if there are no
elements to transfer.
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel
Too minor to require h5committest
Purpose:
Bug Fix
Description:
Trying to create the root group or the working group ("/" or ".") fakes out
HDF5 so that it neither creates a group nor returns an error.
Solution:
H5G_namei now throws an error if it was supposed to insert but didn't.
Platforms tested:
sleipnir, Visual Studio 7 (very minor change)
Bug fix
Description:
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 the "debug" routines to be a little more helpful in certain
situations.
Additionally, fix a locking bug in the symbol table node splitting routine
which could be [one of] the cause[s] of the file corruption in flexible
parallel operation.
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel
h5committested
Bug fix
Description:
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 file is opened for writing.
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel
Too minor to require h5committest
Purpose: Maintenance
Description: Added h5fget_name_f and h5fget_filesize_f subroutines and tests.
Solution: N/A
Platforms tested: arabica (32-bit), sol (64-bit).
Will test on copper after this check-in.
Misc. update:
Purpose:
Fixed a bug that broke daily tests.
SZIP now always uses K13 compression.
Description:
When configured with the --srcdir option, dsets test would look for
a test file in the same directory as the test, instead of in the
directory that contains the source files.
SZIP never needs to use CHIP compression, so the option to set this flag
instead of K13 compression has been removed.
Platforms tested:
Copper
Purpose: New feature and its test
Description: Added API H5Fget_name. It returns the name of file by object ID(file, group, dataset, named datatype, attribute) which belongs to the file. filename.c tests this function.
Platforms tested: h5committest
Misc. update: MANIFEST, RELEASE.txt
Description: After compound datatype with variable-length string in the fields is committed
to file, when it's read back, the size is messed up.
Solution: change the size when it's committed to file by calling H5T_set_loc.
Platforms tested: h5committest and arabica
Misc. update: RELEASE.txt
Purpose: Maintenance
Description: Fortran functions h5dwrite/read_f and h5awrite/read_f
were overloaded with the dims parameter being of type
INTEGER. It was a design flaw. dims should be of type
INTEGER(HSIZE_T). Overloading was done to assure backward
compatibility of 1.4.* branch with hdf5 1.2.* branch.
We promised to remove the old function with INTEGER dims
in 1.6.0. It was removed from the documentation but
was not removed from the source code.
Solution: Finally cleaned up the code.
Platforms tested: Windows 2000 with DEC Fortran, LInux with Intel Fortran,
Solaris 2.7 32/64-bit mode.
Misc. update:
Inform change of APIs
Description:
Many exception constructors are removed. Although the users won't
have to change their code, unless they used to check for the value
of H5::Exception::detailMessage against 0/NULL, which is not very
likely, they might need to recompile their applications.
Code cleanup/bug fix
Description:
Fix configuration files to allow 64-bit compilation of the library with
a 64-bit version of zlib.
Solution:
Moved important compiler flags settings from CC macro to CFLAGS macro.
Instead of setting CC (F9X, CXX) environment variable for compiling for 64-bit
code, users should just set the CFLAGS (FFLAGS, CXXFLAGS) to -q64.
Updated INSTALL file to reflect this change.
Platforms tested:
IBM p690 (copper) w/parallel, FORTRAN, C++, srcdir.
Platforms specific - h5committest does not apply.
Description: I updated HISTORY.txt and RELEASE.txt files, and
ran bin/h5vers to change version number to 1.6.2-post0
Solution:
Platforms tested:
Misc. update:
Description: Changed version to be 1.6.2 and ran bin/release.
Since several files are changed, I am checking them in before
tagging the release
Solution:
Platforms tested: eirene
Misc. update:
Updated with Teragrid cluster new entery.
Added QSC long double -> double known problem.
Removed gcc long long warning since we have added -wno-long-long
to suppress it.
Description: On AIX 5.1, 64-bit parallel build fails when zlib is configured in.
Solution: Problem can be bypassed by removing "const" on line 29 in H5Zpkg.h
I documented the problem and the solution.
Platforms tested: copper
Misc. update:
Description: Few minor editing fixes:
RELEASE.txt
Removed footnote 7 from the table, since it said
that for Windows XP we do not distribute source code.
We distribute source code, but the projects are for Win 2000.
Projects are automatically converted to .NET projects if opened
in the .NET environment. So it was a misleading footnote.
Kent's instructions tell users how to work with the Win2000 projects
in the .NET environment.
INSTALL_Windows_withcpp.txt
Fixed the name of the directory where all.dsw file is found
Added information about libtestD DLLs; they have to be copied to the
system directory before tests can be run.
Solution:
Platforms tested:
Misc. update:
Purpose:
Replaced the table and footnotes in "Supported Configuration Features
Summary" with new versions for Release 1.6.2.
Added "Supported Configuration Features Summary" to the TOC.
Platforms tested:
Reviewed in vi and as a printed copy.
Description: Added Linux 2.4 SuSe to the list of tested platforms.
Solution: JPL machine became available today and I finally
finished testing there. C and C++ passed.
Platforms tested: tb16 at JPL
Misc. update:
made instructions for CW install more clear
Description:
the ZLIB and SZIP library paths are harcoded in the project settings.
in case the user does not want these defaults add a hint to change it
"
If you do not have these libraries installed on these locations, you must change
the path in the Project Settings (menu Edit->Settings->Target->Access Paths)
"
also made clear that the project must be on <install_dir>/hdf5
as described in Windows_install.txt
