Purpose:
Switch from old property list to new generic property list.
Description:
Mainly changed H5Pcreat, H5Pclose, H5Pcopy.
Platforms tested:
IRIX64 6.5, FreeBSD, SunOS 5.7.
Bug fix
Description:
Remove 'const' modifier in prototype for H5D_new, the dcpl_id parameter
needs to be non-const.
Platforms tested:
Eyeballed (reported on gondolin)
Document bug fix.
Description:
When reading or writing to chunked datasets and the data needed datatype
conversion, and the amount of data was more than one conversion buffer,
data in the conversion buffer was getting corrupted.
Solution:
Corrected error in advancing buffer pointer where it was being advanced
by the number of elements instead of the number of bytes.
Platforms tested:
FreeBSD 4.4 (hawkwind)
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)
Code cleanup (sorta)
Description:
When the first versions of the HDF5 library were designed, I remembered
vividly the difficulties of porting code from a 32-bit platform to a 16-bit
platform and asked that people use intn & uintn instead of int & unsigned
int, respectively. However, in hindsight, this was overkill and
unnecessary since we weren't going to be porting the HDF5 library to
16-bit architectures.
Currently, the extra uintn & intn typedefs are causing problems for users
who'd like to include both the HDF5 and HDF4 header files in one source
module (like Kent's h4toh5 library).
Solution:
Changed the uintn & intn's to unsigned and int's respectively.
Platforms tested:
FreeBSD 4.4 (hawkwind)
Bug Fix
Description:
The datatype conversion buffer size was only halfway converted from hsize_t
to size_t and was causing problems. Also, the H5P_peek_<foo> routines have
a bunch of identical code.
Solution:
Finished converting the datatype conversion buffer size to size_t and
cleaned up the implementation of the H5P_peek_<foo> routines to call a
common routine instead of reimplementing a bunch of code.
Platforms tested:
Solaris 2.7 (arabica)
New Features!
Description:
Start migrating the internal use of property lists in the library from the
older implementation to the new generic property lists.
Currently, only the dataset transfer property lists are migrated to the
new architecture, all the rest of the property list types are still using
the older architecture.
Also, the backward compatibility features are not implemented yet, so
applications which use dataset transfer properties may need to make the
following changes:
H5Pcreate(H5P_DATASET_XFER) -> H5Pcreate_list(H5P_DATASET_XFER_NEW)
and
H5Pclose(<a dataset transfer property list>) -> H5Pclose_list(id)
This still may have some bugs in it, especially with Fortran, but I should
be wrapping up those later today.
Platforms tested:
FreeBSD 4.4 (hawkwind)
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)
Code clean/bug fix
Description:
H5FL (free-list manager) code currently is taking an hsize_t as the size
of a memory block to allocate. On many machines, the size of an hsize_t
is greater than the size of a size_t, potentially leading to incorrect
memory allocations in rare circumstances.
Solution:
Changed hsize_t parameters and variables to size_t.
Platforms tested:
FreeBSD 4.3 (hawkwind)
Bug fix/code improvement.
Description:
'all' selections were (ab)using the array reading code and required that
the internal data transfer buffer size be big enough to hold the an entire
slab of the data, which was confusing and limiting for users.
Solution:
Changed 'all' selections to use sequence reading code instead of array
reading code.
Platforms tested:
FreeBSD 4.3 (hawkwind)
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
Bug fix (sort of)
Description:
The RCSID string in H5public.h was causing the C++ code problem as it
was included multiple times and C++ did not like multiple definitions
of the same static variable.
Solution:
Since we don't really make use of the RCSID strings as we have not
installed it in all source files, we decided to remove it.
Platforms tested:
eirene (linux), modi4 (IRIX64-64) both serial and parallel modes.
Bug fix
Description:
Certain combinations of hyperslabs, especially those that have to be
strip-mined during I/O were causing data to be incorrectly transferred.
Solution:
Changed the code in H5S_get_hyper_regions to be more careful about the
regions of the current dimension that are valid. Sometimes, regions which
had already been iterated through were being re-processed.
Platforms tested:
FreeBSD 4.2 (hawkwind)
Bug fix
Description:
Datasets were allowed to be created with chunks larger than the maximum
dimension for each dimension.
Solution:
Compare chunk sizes against maximum dimensions and reject dataset creations
which have chunks too large for the dimensions in the dataspace.
Platforms tested:
FreeBSD 4.2 (hawkwind)
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)
Bug fixes
Description:
Fix two bugs:
- Datasets with vlen datatype which were created but not written to
were not being read back in correctly from the file.
- If an existing space conversion path was found for a conversion, it
was possible that the optimized read/write routines would be used
inappropriately.
Solution:
Patched vlen datatype conversion code to correctly handle zero-length
sequences.
Added a check to the space conversion code to make certain that the
optimized conversion routines are still appropriate when an existing
path is found.
Platforms tested:
FreeBSD 4.2 (hawkwind)
Bug Fix
Description:
Compound datatypes weren't reading background data properly when used
with array or vlen fields.
Solution:
Changed to always read background information from file in those situations.
Platforms tested:
FreeBSD 4.2 (hawkwind)
Code cleanup
Description:
Several places in the code were using -2 as a default value for various
features. However, when a default value is returned from a function that
is supposed to return negative on failure, it was causing confusion and
extra work for users to check for the special value.
Solution:
Replaced hard-coded -2 values in the code with symbolic names, then changed
symbolic names to 0 instead of -2.
Platforms tested:
FreeBSD 4.2 (hawkwind)
Backward compatibility code
Description:
Add in code to allow the library to emulate the v1.2 API and behavior.
Platforms tested:
FreeBSD 4.2 (hawkwind)
Bug fix
Description:
The optimized MPI-IO calls, H5S_mpio_spaces_write/H5S_mpio_spaces_read,
are changed for collective data transfer only since they
call H5FD_mpio_setup to do setup to eveually call MPI_File_set_view
in H5FD_mpio_read or H5FD_mpio_write. MPI_File_set_view is a
collective call. Letting independent data transfer use this
route would result in hanging.
Solution:
For now, the checking is being done in
H5D_write and H5D_read before H5S_mpio_spaces_write/H5S_mpio_spaces_read
is called because the checking code in H5S_mpio_spaces_xfer, though with
the right idea, is not correct yet.
Platforms tested:
IRIX64-64 parallel.
Bug fix (feature, kind of)
Description:
The library used to hang if a collective dataset read/write request
does not have the same number of eventual MPIO request. Part of the
reason is that H5FD_read/H5FD_write immediately returns succeess
if it sees the request size is 0. This caused problem since other
processes with I/O to do would be hanging by waiting for the early
returned process(es).
Solution:
H5FD.c: disable the early return code in parallel mode. Make it
go on even with "nothing" to transfer.
H5D.c: the optimized MPIO xfer routines can handle collect calls correctly
when the condition is right (e.g., no conversion). When the COLLECTIVE
request cannot be handled correctly without the risk of hanging, the
COLLECTIVE is changed to INDEPENDENT calls for the eventual MPIO
calls.
Platforms tested:
IRIX64 parallel (-64, n32), IRIX64 -64 sequential, Linux sequential.
Bug fix
Description:
There is typo in the H5D_write function which reported the
optimized write failure as a H5E_READERROR.
Solution:
Replaced it with the correct H5E_WRITEERROR code.
Platforms tested:
modi4 parallel (compiled H5D.o only).
Maintainance & performance enhancements
Description:
Re-arranged header files to protect private symbols better.
Changed optimized regular hyperslab I/O to compute the offsets more
efficiently from previous method of using matrix operations.
Added sequential I/O operations at a more abstract level (at the same level
as H5F_arr_read/write), to support the optimized hyperslab I/O.
Platforms tested:
Solaris 2.6 (baldric) & FreeBSD 4.1.1 (hawkwind)
cached instead of in separate structures. This reduces the amount of memory
the hash table uses by about half. This is the initial step along the path of
speeding up the metadata caching.
** src/H5Tconv.c
** src/H5Tpkg.h
** src/H5Tpublic.h
The H5T_conv_struct_opt() function had a design flaw -- it
didn't keep information about the stride to use to step
through the temporary/background-value buffer and thus nested
invocations would clobber each other's temp buffers. This was
fixed by splitting the `stride' argument into `buf_stride' and
`bkg_stride' arguments for all the conversion functions. THIS
IS AN API CHANGE, but users will get a compiler warning when
they pass their conversion function pointer to H5Tregister().
** src/H5T.c
** src/H5Tprivate.h
Added a bkg_stride argument to the H5T_convert() definition in
order to fix a bug related to the optimized compound datatype
conversion function.
** src/H5T.c
** src/H5A.c
** src/H5D.c
** src/H5Ofill.c
** src/H5P.c
Added bkg_stride=0 argument to the H5T_convert() calls.
** test/dtypes.c
Added a test for the H5T_conv_struct_opt() bug fixed above.
** src/H5FL.c
The H5FL_term() function should return non-zero even when it
couldn't free all the free lists do to their being used by
some other package. When that other package terminates it
will return non-zero, causing H5FL_term() to be called
again. This fixes some of the `infinite loop closing library'
messages.
** tools/pdb2hdf
Uses print_version() instead of doing that itself.
** src/H5Ppublic.h
Renamed H5Pget_gc_reference() declaration to make it match the
definition.
** src/H5FDlog.c
Added API tracing macros.
Removed `const' qualifier from a `char*' member of a struct
which was allocated on the heap.
** src/H5TB.c
Added curly braces to a couple deeply-nested `if' statements
to make them clearer and to shut up the increadibly stupid and
just plain incorrect gcc warning about ambiguous `else'.
** test/titerate.c
Removed incomplete initialization in favor of memset() for one
auto variable to stop compiler warnings.
** tools/Depencencies
Regenerated to remove references to h5dumputil.c
has turned off error reporting in the library.
Also, changed the way property lists are managed and closed so that they
can be automatically closed when the library terminates.
Bug fix for parallel mode.
Description:
H5FD_mpio_tas_allsame was called for all cases, even when
MPIO is not used for access. That corrupted the internal
file handle structure.
Solution:
Define a macro, IS_H5FD_MPIO(f), for testing if f is opened with
MPIO access. Will call H5FD_mpio_tas_allsame only if this
condition is true.
Platform tested:
O2K, both -64 and -n32 modes.
----------------------
./configure.in
./src/H5config.h.in [REGENERATED]
The /usr/ncsa/{include,lib} directories are only added if they
actually exist. This fixes a warning on some systems.
Checks for the <pdb.h> header file and also for either the PDB or Silo
library, and if found prepares to compile the pdb2hdf program.
./config/distdep
Relative path names for include files are changed to base names since
the makefile contains the logic for searching and since it's likely
that building the .distdep files happed from a location other than
where they would be used in the file system.
./config/conclude.in
Fixed shell errors when `for' loops iterate over nothing for the
`uninstall' target.
./src/H5D.c
./src/H5Oefl.c
File names for the external files are added to the heap when the
dataset is created instead of when the object header is written. This
fixes a rare infinite recursion bug.
./src/H5FD.c
./src/H5FDpublic.h
Optimization to the free list causes H5FD_alloc() usage to go from >10
seconds to <0.4 second for one example (converting a 30MB equation of
state file from PDB to HDF5 format). The optimization is to simply
keep track of the largest item in the free list and not search the
free list when the largest item is not big enough to satisfy the
request.
./src/H5FDcore.c
./src/H5FDcore.h
./test/h5test.c
If the `backing_store' property is true then a flush causes the entire
contents of memory to be written to the specified file. This is in
preparation for the ASCI/red optimizations and is currently tested by
the pdb2hdf `--cached' switch.
./src/H5Odtypes.c
Wrapped three long lines.
./tools/Makefile.in
./tools/pdb2hdf.c [NEW]
A PDB-to-HDF5 translator. It only translates meta data -- the
resulting HDF5 points into the PDB file for the raw data.
but I fixed lots of misc. compiler warnings in other code and also tracked down
the memory overwrite bug that was causing the development branch to core dump
on most machines.
----------------------
./src/H5D.c
Added additional elements to a variable initializer in
H5Dvlen_get_buf_size() to shut up a warning message. Also
added the API tracing call.
./src/H5F.c
Added file opening optimizations. If the driver doesn't
support the ability to determine when two file handles refer
to the same file (like MPIO and GASS) then H5F_open() makes
fewer calls to the driver's open callback. Also, if the
tentative file access flags are the same as the original flags
then H5F_open() makes fewer calls to the file device.
./src/H5FD.c
./src/H5FDprivate.h
./src/H5FDpublic.h
Added H5FD_get_class() so the library can get information
about what file driver callbacks are defined. This will be
useful when more optimization functions are added to the VFL,
such as for MPIO derived datatype I/O.
./src/H5FDcore.c
./src/H5FDfamily.c
./src/H5FDmpio.c
./src/H5FDmulti.c
./src/H5FDsec2.c
The driver symbols (like H5FD_CORE, etc) are actually function
calls. The functions were fixed to return correct values even
after calling H5close().
./src/H5FDmulti.c
./src/H5FDmulti.h
Added support for opening a file when parts are missing (only
if the caller explicitly allows that in the file access
property list).
Moved some common code sequences into macros or functions.
Added better support for reopening files. All the application
has to know is that the file is a multi file and the base name
from which all the member names are created.
More debugging output when the file is opened with the
H5F_ACC_DEBUG flag.
Fixed various bugs.
./src/H5Fistore.c
Chunked raw data was accidently allocated as meta data instead
of raw data.
./src/H5I.c
The H5Iget_type() function fails when invoked with an old
object ID (an ID which has been closed down).
./test/h5test.c
Added an extra argument when setting the multi file access
property lists so the test fails if it can't open one of the
sub-files.
./tools/h5ls.c
Improved the algorithm for deciding what file driver to
use. It basically tries all of the predefined drivers and is
now able to open family, split, and multi files without
looking for special characters in the file name.
Added `-e' and `--errors' switches which cause errors from
libhdf5 to be reported on stderr in addition to the simple
error message displayed by h5ls.

./src/H5Smpio.c
The `driver_id' for a file was accidently put in two
structs. I removed it from the H5F_file_t struct since it's
really an attribute of the VFL stuff.
More careful incrementing/decrementing the driver ID to fix a
memory leak.
./src/H5P.c
Rewrote H5Pcreate() in terms of H5P_copy() of a default
property list. This fixes some referencing counting bugs.
----------------------
./src/H5D.c
./src/H5F.c
./src/H5Fistore.c
./src/H5Smpio.c
Incorporated previous changes into MPIO special cases. These
are mostly due to the fact that most of the members of the
file->shared->fapl struct have been moved into the
file->shared->file->shared struct (`file' is an H5F_t*).
./src/H5I.c
Fixed a bug with closing the library w.r.t. the VFL stuff. The
VFL layer introduced reference counts on object ID's and the
library termination functions freed these objects in the wrong
order. Now H5I_clear_group() does not normally remove objects
with a reference count larger than one because it assumes that
those objects are currently in use by the library.
----------------------

./src/H5FDmulti.c [NEW]
./src/H5FDmulti.h [NEW]
./src/Makefile.in
./src/hdf5.h
The split driver was reimplemented as a more general "multi"
driver which is capable of splitting data into multiple files
like the family driver except the partioning is done by memory
usage type instead of address. The H5Pset_fapl_split()
function just calls H5Pset_fapl_multi() with arguments which
prepare to split the address space into two files: meta and
raw data.
This is the first version. I plan to allow the open() call to
relax a bit which would allow one to open an hdf5 file when
only the meta-data file is present. This would allow a very
large file to be split and stored on tape and the relatively
small meta file to be mirrored on disk to allow limited
browsing of the file (any request for raw data would fail).

./src/H5FDmpio.c
./src/H5FDsec2.c
Added the ability for a file driver to store information in
the superblock which would be needed if the file were opened
again later for reading. The format is driver-defined which
allows users to extend it however they like.
./doc/html/H5.format.html
Added information about the new driver information block of
the superblock. This is where file drivers store information
they need in order to reopen the file later.

The file access properties and the file access property list
were decoupled, which allows the property list to more cleanly
contain properties for various levels of the file and which
allows the property list to be modified more cleanly when
opening files.
./src/H5.c
./src/H5FDpublic.h
Removed H5FD_MEM_META and H5FD_MEM_GROUP since they're never
used.
./src/H5D.c
Changed the way we detect the MPIO driver in all these special
cases.
./src/H5F.c
./src/H5Rpublic.h
./test/tfile.c
The default file sizeof(offset) was changed to be a function
of haddr_t instead of hsize_t.
THE H5RPUBLIC.H DEFINITIONS WILL HAVE PROBLEMS IF THE USER
CREATES A FILE WITH NON-DEFAULT OFFSET AND SIZE SIZES!
./src/H5F.c
Fixed an uninitialized memory access bug in file closing
related to the VFL.
./src/H5T.c
./src/H5Tpublic.h
Added an H5T_NATIVE_HADDR predefined datatype which
corresponds to the `haddr_t' type.

Reformatted long lines.

./test/cmpd_dset.c
./test/dsets.c

Removed the H5F_ACC_DEBUG flag from file creation/open calls.
./test/big.c
Plugged a memory leak.
./test/h5test.c
Added support for the `multi' driver.
Removed #warning about not having the stdio driver. Plans are
to not implement it since the sec2 driver serves the same
purpose and testing didn't show any difference in execution
times between the two.
----------------------
This extensive change is the virtual file layer implementation. I've
ported and tested the sec2, family, and core drivers and only ported
the mpio driver (Albert will test it). So if you need MPIO I would
recommend sticking with the previous version for a while.
You will get a few compile warnings about split and stdio drivers not
being implemented and possibly tracing information not inserted in
some of the drivers. You can safely ignore them but I plan to fix
them.
I'm still working on the split driver because I just realized that it
needs a part of the VFL that isn't written yet.
Documentation is being updated also because there were some minor
changes (mostly just name changes). It should be available on my web
site later this week.

Modified to work with the virtual file layer by calling H5FD_*
functions instead of H5F_low_* functions and by passing file
access and data transfer properties by object ID instead of
pointer.
Changed H5D_transfer_t to H5FD_mpio_xfer_t since the
COLLECTIVE vs. INDEPENDENT transfer mode is specific to the
MPIO file driver.
Moved MPIO-specific stuff into the MPIO driver.
./src/H5B.c

Added major error number H5E_VFL for virtual file layer
related errors.
./src/H5F.c
./src/H5Fprivate.h
Changed the logic that controls whether the boot block is
written. Instead of assuming that the first call to write the
boot block is only to allocate space, I've added a function
argument which makes this explicit.
Changed the way files are compared so that a driver-defined
comparison function can be called. Files which belong to
different drivers are always considered different.
Removed H5F_driver_t since file drivers are now identified by
object ID instead of a special non-user-extendible datatype.
Removed all the hard-coded low-level file properties which
have been replaced by the various file drivers.
./src/H5I.c
./src/H5Iprivate.h
Added the H5I_inc_ref() which was removed a few months ago

file layer which allows file drivers to override much of it.
./src/H5P.c
./src/H5Ppublic.h
Moved file driver-specific code into the various file driver
files.
The H5Pcopy() and H5Pclose() functions make calls into the
virtual file driver to manage the memory for driver-specific
file access and data transfer properties.
./src/H5private.h
./src/H5public.h
The `haddr_t' type is now public.
./test/tfile.c
Added a few more comments.
