Bug Fix
Description:
Resolved issues with broken sanity checks that were failing when the 'b2'
debugging package was enabled (v2 b-tree debugging):
- Fixed outdated assertions that would not compile. They now compile
and function correctly.
- Removed too far outdated assertions that would require too much
unnecessary refactoring of code in order to satisfy their
initial purpose.
- Re-enabled b2 debugging package when "--enable-debug=all" is
specified on the configure line.
Tested:
jam, smirom, linew
Description: Fixes a problem in H5F_close_mounts where it wouldn't correctly
reshape the "child" array when unmounting files. Test added for this case.
Also fixed a potential bug in H5F_unmount where that routine reshapes the child
array.
Tested: kagiso linew smirom (h5committest)
Description: H5Iis_valid function added. This function checks if the id is
valid (i.e. it is currently registered and visible to the application), and
returns TRUE if it is valid, or FALSE otherwise. It should never return an
error.
Tested: kagiso, linew, smirom (h5committest)
Description: H5Ovisit and H5Ovisit by name will now check for a positive return
value from the first callback. Test added for this case.
Tested: kagiso
Description:
In June, we discovered a bug in Windows which only affected specific timezones with the mtime test. This bug was promptly fixed, but never documented. This checkin adds a note to the release document.
Description:
- Remove need to set LD_LIBRARY_PATH when using shared szip library.
- Libtool 2.2.6a is now used to generate libraries.
- 'make check install' dependency bug is fixed, and should no longer
break the build.
- removed hard coding of shell in config/commence.am, as this causes
problems on Solaris with the new version of libtool.
- RELEASE.txt with appropriate changes.
Tested:
- kagiso, smirom, linew (merged from 1.8, pretty quick tests)
Description: Added a new function, H5O_alloc_shrink_chunk, which removes all
null messages from a chunk and shrinks the chunk appropriately. Modified
H5O_merge_null to call this function when a null message is created with a size
>= 64k. Tests added for this functionality.
Tested: kagiso (h5committest on 1.8 version)
Description: Improved external link traversal of h5dump. h5dump will now
properly avoid all cycles, even those spanning multiple files. Improvement
to the output of committed datatypes. Committed datatypes are now checked
for uniqueness (like other objects). Tests added for these cases.
Tested: kagiso, linew, smirom (h5committest)
Various bug fixes & cleanups with VFDs and file free space changes,
along with cleaning up compiler warnings.
Enable more VFDs (for 'make check-vfd' testing) for many tests.

Description: Fixes a possible datatype id leak that could occur during compound
datatype conversion, or more precisely, when unregistering those conversions.
Datatype ids normally registered by the library are no longer visible to the
application via H5Fget_obj_ids and H5Fget_obj_count.
Tested: kagiso, linew, smirom (h5committest)
Description: The optimized "subset" compound conversion function would
improperly copy the "blank" space at the end of compound types. Modified
H5T_conv_struct_init to detect when the subset type has extra space at the end,
and calculate the size of the data that should be copied into the conversion
buffer for each element. Changes to the functions that implement these
conversions.
Tested: kagiso, linew, smirom (h5committest)
Description: Adds capability to h5ls to traverse external links when the -r
(recursive) option is given. Changes to the way absolute path names are patched
in h5trav.c. Changes to the way recursive traversal starting from a non-root
group is handled (which also fixes some preexisting issues). Tests added for
these cases.
Tested: kagiso, smirom, linew (h5committest)
Description: Added configure test to see if pointer alignment restrictions are enforced (as in dereferencing an unaligned pointer causes an error). Added code in H5Tvlen.c to avoid dereferencing unaligned pointers, conditionally compiled based on the configure test. Added test case in dtypes.c which would previously cause such machines to fail.
Tested: kagiso, smirom, linew (h5committest); linew64
> 1.
Description: Added a new field 'app_count' to H5I_id_info_t struct, to track
the reference count on an id due to the application. the old 'count' field
tracks the total. Generally any id visible to the application gets placed
in app_count. Added app_ref boolean parameter to H5I_inc_ref, H5I_dec_ref,
H5I_register, H5I_clear_type, and a few other functions, to specify whether
the operation(s) being performed on the id(s) are due to the application
(TRUE) or not (FALSE). Test added for this case.
Tested: kagiso, smirom, linew (h5committest)
datatype versions are encountered.
Description: The library now recognizes some problems with datatype versions in
H5O_decode_helper(), and, if not performing strict format checks, automatically
corrects them. Framework added for other message decode routines to
automatically correct file errors. Datatype version information added to
h5debug.
Tested: kagiso, smirom, linew (h5committest)
Added notes about:
- bugzilla 1068: revising class hierarchy to move Attribute out.
- replacing IdComponent::dereference with new H5Object member functions
and constructors in various other classes.
Description:
Moved mount table from top file structure to shared file structure. Moved
parent out of mount table and back into top file structure. Mounted files can
now be accessed from any handle of the parent file. Changes to how files are
closed. Stricter cycle checking on mounted files. Removed unused function
H5F_has_mount().
Tested:
committest in 1.8 branch. Committing now due to the urgency of the fix. No
changes here are specific to the trunk, but I will keep an eye on the daily
tests.
the file didn't have the data. It happened because each handle had its own
object structure, and the empty one overwrote the data with fill value. This is
fixed by making some attribute information like the data be shared in the
attribute structure.
Tested on smirom, kagiso, and linew.
Description:
Write documentation for building HDF5 with the latest version of Visual Studio, 2008. The process is very similar to building with Visual Studio 2005, but with an automatic project-file conversion beforehand.
Also adapt commandline build scripts for Visual Studio 2008 as well.
Tested:
VS2008 on WinXP
Description:
When specifying library search path in Visual Studio, use the DLL folder for zlib. Previously we pointed to the "lib" folder, which was causing confusion.
Description:
Modify Windows documentation to support Intel Visual Fortran 10.1. We have tested it in our Virtual machines, and have fixed the problems we were encountering.
Also, add a new parameter to the hdf5build.BAT and hdf5bt.BAT build scripts to support IVF 10.1.
Tested:
VS2005 with IVF 9.1 and 10.1 on 32-bit XP

Description: Removing make target "check-perform". The extra target is unneeded
because the perform tests don't take as long to run as initially
anticipated, and can be lumped in with 'make check'.
Tested: kagiso

Description:
Small changes, such as commenting out an additional test and fixing the search path, have been added to the MinGW install instructions.
Tested:

Description: new autotool version information was missing from 1.9
documentation. It was added to 1.8, but I forgot to put it in
the trunk when I did that update. It's there now.
New versions: Automake 1.10.1, Libtool 2.2.2
Tested: none needed, doc update only.
Description: Tests in perform directory were never getting run, and
h5perf* programs were not being installed.
Solution: Added another build option, 'make check-perform', which runs the
tests in the perform directory. Also modified the Makefiles in the
perform directory to install (with 'make install') h5perf when
parallel is enabled, and h5perf and h5perf_serial when parallel
is disabled.
Tested: kagiso, smirom, linew
Bring r14737 back from the 1.8 branch: Fix bug which would

- h5import bug on Windows w/binary datasets. fread in windows needs a binary file
to be open with rb instead of r otherwise it terminates execution if an end
of file character is found on the input file. Besides that the binary file
generated needs to be open with wb , otherwise an end of line character is
read twice. PVN - 2008/2/19
Description:
List the new HL C examples that were added in the last checkin. Rather than listing each one individually, we give a brief summary, and instructions for how to test them.
Description:
This is the same patch that Mike McGreevy helped me with on the 1.8 branch. The latest cygwin DLL has trouble with the global timezone variable. Now in configure, we target CYGWIN with a case statement, and avoid the problem.
Tested:
Cygwin on WinXP
Description:
The collection of HL C examples that we distribute for Windows is incomplete. I wasn't aware of it until Pedro pointed it out, because we use different (although similar) names for the generated files. This checkin changes the naming to follow Linux, in preparation to add the rest of the HL examples to Windows.
Note: I believe I've updated the MANIFEST accordingly, but I may have missed something-- I'll check on Linux shortly after this commit.
Tested:
VS2005 on WinXP
VS.NET on WinXP
Fold all the updates made for v1.8.0 release to the main trunk.
Versions are from r14548 to r14556. Changes are,
Updated section 4 for v1.8 release.
(May still check the v1.6 INSTALL to see if something can be adopted from
there. But this is good for v1.8 release.)
Moved the section 2. "Warnings about compilers" to Appendix A; renumbered
section 3-7 to section 2-6 and fixed all section references.
Updated Website names from ncsa.uiuc.edu to hdfgroup.org or hdfgroup.uiuc.edu.
Updated section 1-3 and some of section 4.
Quick editorial review.
Convert tabs to spaces for consistent display and printing.
Verify and fix links and references.
Moved the following three paragraphs to the Appendix part since they have old
information that are not relevant most recent machines or compilers.
"Large (>2GB) versus small (<2GB) file capability",
"Building and testing with Intel compilers"
"Building and testing with PGI compilers"
Description:
We've run into a bug that was introduced in the latest version of Cygwin, that breaks C99 code using the 'timezone' global variable. As a workaround, we use the -ansi flag, which makes everything compile/link/test correctly
Tested: Cygwin on WinXP
Description:
Wrote documentation on how to use the 1.6 API for a user application-- this replaces the outdated documentation we previously had.
Tested: VS2005 with HDFEOS5
Description:
There are many tests that are unsupported on MinGW because of the way it handles certain syntax in shell scripts (particularly '/'). As a result, we list a few tests that users must comment out in various Makefile.in's. This checkin updates the location of h5stat-- it was formerly in ./tools/misc, but has been moved it ./tools/h5stat.
Tested:
MinGW on WinXP
Removed the stream-vfd from the basic library code.
(The stream-vfd source files are not removed yet but the MANIFEST has been
updated to NOT release those stream-vfd source files.)
Platforms tested:
Kagiso and smirom.
Then test the release tar ball in kagiso.
Description:
Previously, we provided a static h5tinit.c with our Windows distribution, and provided instructions to optionally generate it. Now, we will incorporate it as part of the default build process, to emulate other platforms more closely.
Tested:
VS6
VS2005
Description:
We recently uploaded new versions of our external library binaries to support more compiler configurations. This check-in is to point to the new location in our documentation.
Tested:

- h5dump lists groups and attributes in requested orders (by name and
creation order, both ascending and descending). PVN - 2007/10/5
- h5import imports string (text) data. PVN - 2007/10/5
Description:
This updates the command-line build process to handle structural changes we've made in the HDF5 project files. Also, we add support for two new options:
/fort - to build Fortran libraries
/useenv - to allow users to specify include and libpath directories on the command line as well.
Also updated documentation to reflect these change.
Tested:
VS2005 on WinXP
Description:
There are minor changes in the testing process for Windows with the new test scripts. Specifically, the test output is output to the screen, rather than redirected into files, by default. Also, it is much easier to test parts modularly, and installing DLLs is one step, instead of separated batch files.
Tested:
None, only documentation changed.
Description:
This checkin is another Windows project cleanup, and also extends our Windows support for 64-bit Fortran. Project files are now in VS2005 format, rather than VS.NET. A couple projects have been renamed to be more descriptive (*cstub rather than *_lib), and project settings make better use of build macros. This will make them much easier to update in the future.
Tested:
VS2005 on WinXP 32-bit
VS2005 on WinXP x64
Description:
Previously the process of generating h5tinit.c, as well as the Fortran type files, was very manual on Windows. For Fortran, the process included opening 4 different solutions, and running 4 different commands from the prompt. I've made things very much more automated, and now only requires only building one project for either C or C/Fortran. Running the commands to generate the file is done automatically.
Tested: VS.NET
Description:
Visual Studio does not have the function siglongjmp. Therefore, we have created a new configure flag H5_HAVE_SIGLONGJMP that tests for this. We use this within H5detect.c.
Tested:
VS.NET
h5committest
Description:
At a previous seminar, it was brought up that the naming scheme for Windows debug DLL is inconsistent. Specifically, some use *ddll, while others use *dlld. *dlld is more widely-used, so we decided this is "correct". This changes others to use this scheme, and adapts other projects / install scripts / documentation.
Tested:
Visual Studio .NET on WinXP
Description:
Previously, we needed to force symbol definition "gethostname@8" for compatibility with old versions of Visual Studio. It appears that Visual Studio no longer requires this, so we remove it. This makes the build process on 64-bit much smoother.
Also minor updates to main documentation, command-line documentation, and removed codewarrior and INTEL docs.
Tested:
VS.NET
VS2005
chkmanifest
Description:
The Windows documentation on generating H5tinit.c was lacking special instructions for Visual Studio 2005. Specifically, Windows does not support the function "siglongjmp". Previous versions of Visual Studio will ignore this function, but VS2005 produces an error.
Tested:
VS6
VNET
VS2005
Description:
Explain why Fortran isn't supported on MinGW and give users an "unsupported" alternative. Also re-worked the main documentation to clarify using the HDF5 DLL libraries.
Tested:
None needed.
Description:
This makes major updates to the Windows installation documentation, to account for the switch from VS6 to .NET. Installation instructions for 6.0 can also be found in INSTALL_Windows_Short_MSVS6.0.TXT, although it's noted that we are phasing out our VS6 support.
Also added install instrctions for MinGW, to reflect our initial support. Updated MANIFEST for new file checkin.
Tested:
Instructions for each configuration have been tested.
Description:
Updated RELEASE.txt to reflect support for 64-bit Windows. Also updated the testing table, and removed some old Windows-related issues that are no longer present.
No testing needed.
I've also updated our Windows documentation file to include 64-bit instructions. The process is fairly tedious right now, but we hope to make it more straight-forward when we depreciate 6.0 and re-work our project files.
Tested:
32-bit WinXP: VS6, VS.NET, and VS 2005
64-bit WinXP: VS.NET and VS 2005
Change back to clearing memory buffers by default, but give users option
to disable this, for performance reasons (--disable-clear-file-buffers).
Also, add configure option (--enable-using-memchecker) to conveniently

"make check-vfd" will now run all tests in the test directory with different
file drivers (at least, all of those tests that use the testing framework's
FAPL). Tests that fail will be skipped.
This is not a perfect fix, but is better than nothing.
Along with this change, check-vfd should be added to the Daily Tests.
Description: Added support for HPUX11.23
Solution: Added configuration file for the system.
Both C, C++, F90, HL 32-bit and 64-bit are supported. Known problems:
C++ library will not build in 64-bit mode if shared is enabled.
Platforms tested: HPUX 11.23 at UMKC
Misc. update:
Configuration feature
Description:
'make install' now tests both static and shared libraries if both are installed.

Bug fix
Description:
Changed the semantics of --enable-stream-vfd and --enable-shared.
Both are now disabled by default when parallel HDF5 is being built.
Solution:
Both shared and stream-vfd are disabled by default in parallel, but can
be enabled explicitly if the user chooses.
Before, shared was always enabled by default and stream-vfd was
always disabled in parallel.

Description:
The fix of the TR was put in the wrong session (new configure feature).
It is moved to the proper session (bug fix on configure.)
Bug fix.
Description:
The ${TR}, though avoid the error, is inconvenient. It is needed
because configure.in use the char range in the style of 'a-z'.
The other style of '[a-z]' is more commonly accepted by all tr
but autoconf tends to strip away [], making the syntax rather
clumsy.
Solution:
Learned from autoconf that it avoids the use of character range
by just spell all the letters out. Changed our tr commands to
use those variables defined by autoconf. Also removed the
definition of ${TR} since it will cause inconsistancy when
autoconf also use plain 'tr' in its generated code.
The Makefile.in are changed because the elimination of ${TR} from
configure triggered its removal from all Makefil.in. That is okay
because ${TR} is not used at all in Makefile.
Platforms tested:
h5committested. (sol failed to connected). also tested in shanti
using both /usr/ucb/tr and /bin/tr (the bad one before.)

This initiates the "unstable" phase of the 1.7.x branch, leading up
to the 1.8.0 release. Please test this code, but do _NOT_ keep files created
with it - the format will change again before the release and you will not
be able to read your old files!!!

Solution:
There's too many changes to really describe them all, but some of them
include:
- Stop abusing the H5G_entry_t structure and split it into two separate
structures for non-symbol table node use within the library: H5O_loc_t
for object locations in a file and H5G_name_t to store the path to
an opened object. H5G_entry_t is now only used for storing symbol
table entries on disk.
- Retire H5G_namei() in favor of a more general mechanism for traversing
group paths and issuing callbacks on objects located. This gets us out
of the business of hacking H5G_namei() for new features, generally.
- Revised H5O* routines to take a H5O_loc_t instead of H5G_entry_t
- Lots more...
Platforms tested:
h5committested and maybe another dozen configurations.... :-)
New feature
Description:
Add in baseline "object copy" code from Peter [in the form of a new API
routine: H5Gcopy()]. There's still some work to do (like handling variable-
length datatypes and possibly support for references) and it hasn't been tested
on mounted files yet, but the core functionality is there and working
correctly.
I've also got a set of patches to update the 1.6 branch with tweaks to
keep the branches mostly in sync, but Elena will kill me if I import them
before the 1.6.5 release is out... :-)
Platforms tested:
FreeBSD 4.11 (sleipnir)
h5committested
Updated RELEASE.txt
Description:
Mentioned that h5c++ and h5fc now support linking against shared libraries.
Platforms tested:
documentation change only
Update copyrights.
Description:
Solution:
This should address almost all of the "simple" cases in the repository.
There's still work to do, but it's going to require actually thinking about
the files in question instead of just copying & pasting.
bug fix
Description:
an assertion after the search for objects was saying that the number of
objects in file should be > 0
removed it, since there can be a case where the number of objects is 0.
in this case this was found by a case where zlib was not present and the output file
was not written any objects to
note: this was only detected on the windows batch files, that do not have a conditional
condition to not run tests when a filter is not present
Solution:
Platforms tested:
linux
Misc. update:
Bug fix
Description:
Fix "double root open" bug and apply same fix to datasets & named datatypes.
Also fix bug in symbol table entry lookup code that would "transfer" an
object from one file handle to another file handle when the two file handles
were opened on the same actual file.

Purpose:
Add the known problem for IRIX6.5 C version >7.4.
Description:
Somehow SGI's MPI implementation doesn't free MPI_TYPE_entries,
So for large application to use MPI derived datatype, environment
variable MPI_TYPE_MAX needs to be reset.

Bug fix
Description:
Fix core dump when checking whether to invalidate the name of an object
when unlinking an object in a group opened through an object reference.
Solution:
Check if names of various objects are valid before comparing them, etc.

Add more comments for collective chunk IO supports.
Description:
On some platforms that use mpich library internally, we have no way to check mpich version number. We have to manually turn off the collective IO supports.
One example is Altix(cobalt). Just put a comment there so that we won't forget about this.

Misc. update:
Description:
Added missing member functions:
H5::CompType::getMemberArrayType
H5::CompType::getMemberVarLenType
H5::AbstractDs::getArrayType
H5::AbstractDs::getVarLenType
H5::CommonFG::openArrayType
H5::CommonFG::openVarLenType
H5::PropList::copyProp -- this will replace the current
H5::PropList::copyProp in later releases due
to incorrect prototype.
H5::IdComponent::getHDFObjType
Bug fix
Description:
Correct problems when querying information about a group that was opened
by dereferencing an object reference.
Solution:
Read in symbol table information instead of rely on it being cached.

Bug fix
Description:
If a named datatype is copied and the copy is used to create a dataset,
the dataset would inadvertantly refer to the original named datatype instead
of a local (possibly modified) copy of the named datatype.
Solution:
Fixed datatype copying routine.

Description: There was a bug in the calculating code of the Fletcher32
checksum in the library before v1.6.3. The checksum value wasn't consistent
between big-endian and little-endian systems. This bug was fixed in
Release 1.6.3. However, after fixing the bug, the checksum value is no
longer the same as before on little-endian system.
Solution: Made the library compare both the correct checksum and incorrect
checksum generated from v1.6.2 or before. This makes the library be
backward compatible but not forward compatible.
Platforms tested: h5committest and fuss.
Misc. update: Documented the forward incompatibility problem in the
Known Problem section in RELEASE.txt
Modification on .Net and Intel part
Description:
In batch mode, there should be no options to choose build Only HDF5 C or both C and C++ library
with visual studio .net or intel compiler for the time being

Misc. update:
Bug fix & code cleanup
Description:
Don't unmount child files from a parent file if the parent file is
being held open by an object.
Also, moved the mounting routines into their own source file and the
superblock routines into their own file also.
Solution:
Moved the code for unmounting child files down in the H5F_close routine
and also add checks to the file and group mounting code to unmount child
files when the last object holding open a file closes.
Platforms tested:
FreeBSD 4.11 (sleipnir)
h5committest
Bug fix
Description:
Fixed bugs that caused tests to be unable to find testhdf5.sh during
daily tests, and another that broke sol and shanti.
Solution:
When tests are run, their path is ./$testname .
When scripts are run, their path has no leading "./". Fixed.
Sol and shanti don't recognize the -e option for test, but they do know
-f. Fixed.
Also modified release notes.
Platforms tested:
mir, shanti, heping
Bug fix
Description:
When a series of files is mounted on one another and one of those files
is not unmounted, the library gets confused at shutdown and goes into an
infinite loop in the file interface.
Solution:
If there are still files left in the "closing" state when shutting down
the file API, iterate over those file IDs and unmount any child files that we
find mounted on those files.
