Bug Fix/Code Cleanup/Doc Cleanup/Optimization/Branch Sync :-)
Description:
Generally speaking, this is the "signed->unsigned" change to selections.
However, in the process of merging code back, things got stickier and stickier
until I ended up doing a big "sync the two branches up" operation. So... I
brought back all the "infrastructure" fixes from the development branch to the
release branch (which I think were actually making some improvement in
performance) as well as fixed several bugs which had been fixed in one branch,
but not the other.
I've also tagged the repository before making this checkin with the label
"before_signed_unsigned_changes".
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel & fphdf5
FreeBSD 4.10 (sleipnir) w/threadsafe
FreeBSD 4.10 (sleipnir) w/backward compatibility
Solaris 2.7 (arabica) w/"purify options"
Solaris 2.8 (sol) w/FORTRAN & C++
AIX 5.x (copper) w/parallel & FORTRAN
IRIX64 6.5 (modi4) w/FORTRAN
Linux 2.4 (heping) w/FORTRAN & C++
Misc. update:
Description: Restore 6 old error API functions back to the library to be backward
compatible with v1.6. They are H5Epush, H5Eprint, H5Ewalk, H5Eclear, H5Eset_auto,
H5Eget_auto. These functions do not have error stack as parameter.
Solution: Internally, these functions use default error stack.
Platforms tested: h5committest and fuss.
Misc. update: RELEASE.txt
Code cleanup
Description:
Various minor tweaks to clean code up and bring it into closer
syncronization with the release branch.
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel
h5committested
IRIX64 6.5 (modi4)
Code cleanup
Description:
Add destructor to match constructor fr VFLs when they are shut down by the
library.
Solution:
Added H5FD_*_term() routines to "undo" changes made in H5FD_*_init()
routines.
Platforms tested:
IBM p690 (copper)
too minor to require h5committest
A bug fix for windows.
Description:
Many tests failed on windows when stdio driver is on.
I suspect it is the compiler bug.
After some investigation, the symptom is:
The signature of HDF5 file cannot be found.
The real problem is the signature was appended at the end of the whole
file instead of inserting at the starting of the file.
It seems when the file pointer(signature) is reset to the starting of the file,
windows mis-placed it to the end of the file after finding the file is close to
the end.
Solution:
Fortuately, ftell and fseek still function well on windows,
so I use ftell and fseek to force the file pointer to go to the position it is supposed
to go.
Platforms tested:
since the only change in this file is within ifdef WIN32 macro; it won't
affect the mainstream platforms, so I don't have to three platforms.
Platforms to confirm(test with basic function): Linux 2.4
Platforms to throughly test: windows 2000 with VS6.0
test on three different
Misc. update:
A compiling error fixed for windows only
Description:
Use file handler instead of file stream at H5FDstdio.c when using getfileHandle function of windows.
Solution:
see above, however; stdio driver tests failed on windows. I am still investigating the bug.
The current check will not fix the failure of stdio driver test on windows.
The good news is that it won't affect the release since the default driver used for test is sec2 driver and
all tests passed for sec2 driver on windows.
Platforms tested:
windows 2000 and confirmed at Linux.
Since the only change is two-line code inside #ifdef WIN32 #endif macro block,
it is not necessary to test all UNIX platforms. Still confirmed at eirene.
Misc. update:
Bug fix.
Description:
The stdio filer driver is not reducing the file's size in the manner
that the sec2 driver does.
Solution:
Copy code from the sec2 for handling this properly.
Platforms tested:
h5committested
New Feature
Description:
Added support for the lock and unlock function calls for file
drivers. Only FPHDF5 uses this feature. All of these drivers don't
define lock or unlock methods.
Platforms tested:
Linux, Modi4, Sol
Misc. update:
Bug Fix
Description:
Metadata cache in parallel I/O can cause hangs in applications which
perform independent I/O on chunked datasets, because the metadata cache
can attempt to flush out dirty metadata from only a single process, instead
of collectively from all processes.
Solution:
Pass a dataset transfer property list down from every API function which
could possibly trigger metadata I/O.
Then, split the metadata cache into two sets of entries to allow dirty
metadata to be set aside when a hash table collision occurs during
independent I/O.
Platforms tested:
Tested h5committest {arabica (fortran), eirene (fortran, C++)
modi4 (parallel, fortran)}
FreeBSD 4.7 (sleipnir) serial & parallel
Misc. update:
Updated release_docs/RELEASE
Purpose:
New API functions
Description:
Added API functions to return pointer to low-level file handle
(H5Fget_vfd_handle and H5FDget_vfd_handle) and related property list
setting functions(H5Pset_family_offset and H5Pset_multi_type).
Platforms tested:
Linux 2.2(eirene), Solaris 2.7(arabica), IRIX64 6.5(modi4)
New feature.
Description:
Added a "small data" block allocation mechanism to the library, similar to
the mechanism used for allocating metadata currently.
See the RFC for more details:
http://hdf.ncsa.uiuc.edu/RFC/SmallData/SmallData.html
This reduces the number of I/O operations which hit the disk for my test
program from 19 to 15 (i.e. from 393 to 15, overall).
Platforms tested:
Solaris 2.7 (arabica) w/FORTRAN and FreeBSD 4.5 (sleipnir) w/C++
Purpose:
eliminate warnings on win32
Description:
some conversion warnings were being issued
Solution:
added some type casts
Platforms tested:
w2000, linux
changed the HDmemset to include a cast in win32; this was just to eliminate a compiler
warning. probably the macro can also be used in unix
#ifdef WIN32
#define HDmemset(X,C,Z) memset((void*)(X),C,Z)
#else /* WIN32 */
#define HDmemset(X,C,Z) memset(X,C,Z)
#endif /* WIN32 */
the list of previous warnings was

New Feature
Description:
The VFL flush function is called immediately before a file is closed.
This can cause duplicate syncronization actions to occur, if the VFL
close function also performs them.
Solution:
Added 'closing' parameter to VFL 'flush' operation. This allows the VFL
flush function to bypass operations that will be duplicated within the VFL
close function.
Additionally, use the 'closing' parameter to bypass calls to MPI_File_sync()
when set. Since MPI_File_close() also syncronizes the file, this avoids
the terrible performance hit taken when calling MPI_File_sync() as the file
is closing.
Platforms tested:
IRIX64 6.5 (modi4)
Feature
Description:
Added comments that this is intended as an example of file driver.
Added a macro detection at the end to flag if non-public definitions
are used. (only check for H5private.h which is mostly likely used.
Not bullet proof at all.)
Platforms tested:
eirene.
Purpose:
Modify H5Fclose behavior
Description:
The HDF5 actual file close behaves in several ways in terms of if there
are still objects(dataset, group, datatype) opened in file.
Solution:
Added a new file access property, file close degree. It has four values,
H5F_CLOSE_DEFAULT
H5F_CLOSE_WEAK
H5F_CLOSE_SEMI
H5F_CLOSE_STRONG
The way a file is closed is decided by these values.
Platforms tested:
IRIX64 6.5, SunOS 5.6, FreeBSD 4.4
Code cleanup
Description:
Get rid of IDs from internal function calls and some small cleanups from
the old-stype => generic property list conversion.
Platforms tested:
FreeBSD 4.4 (hawkwind)
Bug fix.
Description:
On some systems (linux when not using gcc) 'dev_t' is not actually
a scalar variable. This causes the code which compares dev_t's in
the file drivers to not compile. Also the H5_inline flag was not being
set correctly in the H5private.h file.
Solution:
Set the H5_inline flag to '' (i.e. define it, but don't assign it a value)
if it is not currently defined.
Use DEV_T_IS_SCALAR flag from configure to correctly compare dev_t's using
memcmp instead of a scalar flag.
Platforms tested:
FreeBSD 4.3 (hawkwind), Linux 2.4.2 (chiba city cluster at Argonne)
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)
Purpose:
Code Cleanup
Description:
Updating CodeWarrior Port
Solution:

Platforms tested:
Solaris 2.7 (arabica) Linux 2.2 (eirene)
Code cleanup
Description:
Recent CodeWarrior patches have broken the Unix builds and moved code
around in non-portable ways.
Solution:
Patched things back up to try to accomodate CodeWarrior and still let the
Unix builds work correctly.
Platforms tested:
FreeBSD 4.3 (hawkwind)
code warrior support
and some clean up
the macros file_seek and file_offset_t that were repeated over sevral files were put only in

Purpose:
bug fix for windows MVS
Description:
adding various windows macros to make it work on windows platform
Solution:
see above
Platforms tested:
test on windows 2000, confirmed on linux.
Update
Description:
Changed
#include <hdf_file.h>
construct to
#include "hdf_file.h"
so that the GNU compiler can more easily pick up the dependencies
which it places in the .depend and Dependencies files. Also
regenerated the Dependencies to go along with this.
Platforms tested:
Linux
Code cleanup.
Description:
Fixed _lots_ (I mean _tons_) of warnings spit out by the gcc with the
extra warnings. Including a few show-stoppers for compression on IRIX
machines.
Solution:
Changed lots of variables' types to more sensible and consistent types,
more range-checking, more variable typecasts, etc.
Platforms tested:
FreeBSD 4.2 (hawkwind), IRIX64-64 (modi4)
Purpose:
several warning and bug fix for windows
Description:
different system calls on windows
Solution:
for win32, use only those system calls
Platforms tested:
windows 2000

* H5FD_stdio_query: The `flags' argument is advertised to be output only. Therefore I
added code to zero its value before the feature bits
are assigned.
Bug Fix
Description:
The #ifdef ... #else statement had no line breaks in it. This
caused the compiler on Sangamon to freak out saying the #ifdef
was invalid.
Solution:
Put line breaks in it.
Platforms tested:

Purpose:
a windows bug fix
Description:
support > 2G file on windows NTFS
Solution:
using fsetpos to seek the address
Platforms tested:
windows 2000, confirmed on arabica and eirene.
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.
Tested:
FreeBSD 4.1.1 (hawkwind)
Implemented new feature
Description:
Added data sieve buffering code to raw I/O data path. This is enabled for
all the VFL drivers except the mpio & core drivers. Also added two new
API functions to control the sieve buffer size: H5Pset_sieve_buf_size() and
H5Pget_sieve_buf_size().
Platforms tested:
Solaris 2.6 (i.e. baldric)
** configure.in
** configure [REGENERATED]
** src/H5private.h
** src/H5public.h
** src/Makefile.in
Generates an H5pubconf.h file which is just like H5config.h except all
the preprocessor symbols have `H5_' prepended. This was done so that
the configuration results can be used in public header files without
polluting the namespace.
** src/H5.c
Added H5I_REFERENCE and H5I_VFL to the API tracing code so their names
are printed instead of just numbers.
** src/H5FDstdio.c
** tools/h5import.c
** tools/h5repart.c
** tools/pdb2hdf.c
Changed to use the `H5_' versions of configure results since these
files include only the public API.
** test/big.c
Removed a compiler warning.
** test/h5test.c
Removed unused code.
