Lots of performance improvements & a couple new internal API interfaces.
Description:
Performance Improvements:
- Cached file offset & length sizes in shared file struct, to avoid
constantly looking them up in the FCPL.
- Generic property improvements:
- Added "revision" number to generic property classes to speed
up comparisons.
- Changed method of storing properties from using a hash-table
to the TBBT routines in the library.
- Share the propery names between classes and the lists derived
from them.
- Removed redundant 'def_value' buffer from each property.
- Switching code to use a "copy on write" strategy for
properties in each list, where the properties in each list
are shared with the properties in the class, until a
property's value is changed in a list.
- Fixed error in layout code which was allocating too many buffers.
- Redefined public macros of the form (H5open()/H5check, <variable>)
internally to only be (<variable>), avoiding innumerable useless
calls to H5open() and H5check_version().
- Reuse already zeroed buffers in H5F_contig_fill instead of
constantly re-zeroing them.
- Don't write fill values if writing entire dataset.
- Use gettimeofday() system call instead of time() system when
checking the modification time of a dataset.
- Added reference counted string API and use it for tracking the
names of objects opening in a file (for the ID->name code).
- Removed redundant H5P_get() calls in B-tree routines.
- Redefine H5T datatype macros internally to the library, to avoid
calling H5check redundantly.
- Keep dataspace information for dataset locally instead of reading
from disk each time. Added new module to track open objects
in a file, to allow this (which will be useful eventually for
some FPH5 metadata caching issues).
- Remove H5AC_find macro which was inlining metadata cache lookups,
and call function instead.
- Remove redundant memset() calls from H5G_namei() routine.
- Remove redundant checking of object type when locating objects
in metadata cache and rely on the address only.
- Create default dataset object to use when default dataset creation
property list is used to create datasets, bypassing querying
for all the property list values.
- Use default I/O vector size when performing raw data with the
default dataset transfer property list, instead of querying for
I/O vector size.
- Remove H5P_DEFAULT internally to the library, replacing it with
more specific default property list based on the type of
property list needed.
- Remove redundant memset() calls in object header message (H5O*)
routines.
- Remove redunant memset() calls in data I/O routines.
- Split free-list allocation routines into malloc() and calloc()-
like routines, instead of one combined routine.
- Remove lots of indirection in H5O*() routines.
- Simplify metadata cache entry comparison routine (used when
flushing entire cache out).
- Only enable metadata cache statistics when H5AC_DEBUG is turned
on, instead of always tracking them.
- Simplify address comparison macro (H5F_addr_eq).
- Remove redundant metadata cache entry protections during dataset
creation by protecting the object header once and making all
the modifications necessary for the dataset creation before
unprotecting it.
- Reduce # of "number of element in extent" computations performed
by computing and storing the value during dataspace creation.
- Simplify checking for group location's file information, when file
has not been involving in file-mounting operations.
- Use binary encoding for modification time, instead of ASCII.
- Hoist H5HL_peek calls (to get information in a local heap)
out of loops in many group routine.
- Use static variable for iterators of selections, instead of
dynamically allocation them each time.
- Lookup & insert new entries in one step, avoiding traversing
group's B-tree twice.
- Fixed memory leak in H5Gget_objname_idx() routine (tangential to
performance improvements, but fixed along the way).
- Use free-list for reference counted strings.
- Don't bother copying object names into cached group entries,
since they are re-created when an object is opened.
The benchmark I used to measure these results created several thousand
small (2K) datasets in a file and wrote out the data for them. This is
Elena's "regular.c" benchmark.
These changes resulted in approximately ~4.3x speedup of the
development branch when compared to the previous code in the
development branch and ~1.4x speedup compared to the release
branch.
Additionally, these changes reduce the total memory used (code and
data) by the development branch by ~800KB, bringing the development
branch back into the same ballpark as the release branch.
I'll send out a more detailed description of the benchmark results
as a followup note.
New internal API routines:
Added "reference counted strings" API for tracking strings that get
used by multiple owners without duplicating the strings.
Added "ternary search tree" API for text->object mappings.

offset from the beginning of file.
Platforms tested:
eirene, arabica
Code Cleanup & New Tests
Description:
tmisc.c:
Switched from using H5_HAVE_COMPRESSION flag in favor of
H5_HAVE_FILTER_DEFLATE.
dsets.c:
Switched from using H5_HAVE_COMPRESSION flag in favor of
H5_HAVE_FILTER_DEFLATE.

is not available.
Platforms tested:
Tested h5committest {arabica (fortran), eirene (fortran, C++)
modi4 (parallel, fortran)}
FreeBSD 4.7 (sleipnir)
Purpose:
Add a testing case for shuffling algorithm.
Description:
A control test:
Since shuffling 8-bit array should not change the original result; so we use a
8-bit array to test whether after shuffling the array keeps the same values.
Solution:
Platforms tested:
eirene,arabica,modi4
Misc. update:
Update MANIFEST if you add or remove any file.
Update release_docs/RELEASE for bug fixes, new features, etc.

Code cleanup
Description:
Clean up some compile warnings and have these tests create their data files
with the correct file drivers and directories, etc.
Platforms tested:
FreeBSD 4.6 (sleipnir) w and w/o parallel
Linux 2.2.x (eirene) w/FORTRAN & C++
Solaris 2.7 (arabica) w/FORTRAN
IRIX64 6.5 (modi4) w/FORTRAN & parallel

Description:
Compact dataset is stored in the header message for dataset layout.
Platforms tested:
arabica, eirene.
Update, Bug Fix, and Feature Add
Description:
- Updated how AC_{ENABLE,WITH} help messages were being generated.
Autoconf now gives you an AC_HELP_STRING macro to use to create
them.
- Fixed the problem with Linux LFS on RedHat 7.3 machines. It wasn't
finding getdents64(), so we can't rely on that being present
anymore...
- Added GPFS detection and setting.
- Updated how compression is specified. It's no longer necessary to
test for HAVE_ZLIB_H, HAVE_LIBZ, and HAVE_COMPRESS2. The one macro
{H5_}HAVE_COMPRESSION takes care of all of these.
Solution:
Changed the check for Linux LFS from looking for getdents() to
looking at the version number of the kernel (using the uname -r
command). You can still override with the --enable-linux-lfs switch
if you really believe that your <2.4 kernel has LFS support.
Platforms tested:
Linux (2.2 and 2.4)
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:
Windows is generating hundreds of warnings from some of the practices in
the library. Mostly, they are because size_t is 32-bit and hsize_t is
64-bit on Windows and we were carelessly casting the larger values down to
the smaller ones without checking for overflow.
Also, some other small code cleanups,etc.
Solution:
Re-worked some algorithms to eliminate the casts and also added more
overflow checking for assignments and function parameters which needed
casts.
Kent did most of the work, I just went over his changes and fit them into
the the library code a bit better.
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 for better compatibility with C++ compilers
Description:
C++ compilers are choking on our C code, for various reasons:
we used our UNUSED macro incorrectly when referring to pointer types
we used various C++ keywords as variables, etc.
we incremented enum's with the ++ operator.
Solution:
Changed variables, etc.to avoid C++ keywords (new, class, typename, typeid,
template)
Fixed usage of UNUSED macro from this:
char UNUSED *c
to this:
char * UNUSED c
Switched the enums from x++ to x=x+1
Platforms tested:
FreeBSD 4.4 (hawkwind)
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)
Update
Description:
Changed includes of the form:
#include <hdf5_file.h>
to
#include "hdf5_file.h"
so that gcc can pick them up easier without including the system
header files since we don't care about them.
Platforms tested:
Linux
Code tweak
Description:
Large data arrays were being created on the stack.
Solution:
Hoisted the data variables out of the function(s) and make into static
variables.
Platforms tested:
FreeBSD 4.3 (hawkwind)
Clean up warnings
Description:
The "FAILED" macro is defined by Windows and is causing warnings and
potential errors when compiled on that platform.
Solution:
Change our macro from FAILED to H5_FAILED.
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:
Wrote test to verify new error checking is working correctly.
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 fix.
Description:
Properly detect whether the library has compression support and skip
tests (with messages) if there is no compression.
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)
The "FILENAME" declared extern in h5test.h is not always used.
It was used in h5_cleanup to remove temporary files created
during tests. Not all tests codes have used this routine.
Indeed, quite a few of test programs do "#define FILENAME ".
Also, h5_cleanup needs to work in tandem with h5_fixname.
h5_fixname accepts an explicite base_name argument instead
of using the global variable FILENAME. That is cleaner.
Solution:
Added char *base_name[] as a new argument to h5_cleanup, in
the same style as h5_fixname. Removed "extern char *FILENAME..."
from use. Also, undo some unnecessary declaration of "char *FILENAME"
from some tests which don't use it at all (yet).
Platforms tested:
modi4-64(irix64), arabica(solari2.7), eirene(linux)
(arabica could not launch tests automatically. I had to hack
in LD_LIBRARY_PATH to make them run.)

./src/H5FDmulti.c [NEW]

./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).

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.

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

./src/H5E.c
./src/H5Epublic.h
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
since we finally have a use for it.
./src/H5Ipublic.h
Added the H5I_VFL object ID type to identify file drivers in
the virtual file layer.
./src/H5MF.c
./src/H5MFprivate.h
Moved all the allocation/deallocation code into the virtual
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.

./tools/h5ls.c
Added a `-g' (or `--group') flag that causes information to be
printed about the specified group instead of the group's
contents. (sort of like Unix's `ls -d'). The `-g' can be used
in combination with `-r' to print information about the group
and its contents.
----------------------
./config/irix64
The old (-32) compiler is now supported by setting envrionment
CC='cc -32'. The -64 compiler is the default or you can set
CC='cc -64'.

./INSTALL
./doc/html/Compression.html
./doc/html/Filters.html
Disassociated GNU from zlib. Did not change the introduction
which incorrectly states that compression in hdf5 is available
only if GNU gzip is available (should read zlib).
Changed a typo in INSTALL to match what is documented in
various other places: that zlib 1.1.2 (not 1.0.2) or better is
required for compression.
Added a reference to the main zlib web page in various places.
./src/H5Fistore.c
Fixed a typo in a comment.
./src/H5Flow.c
Removed carriage returns from the end of lines.
./test/dsets.c
The deflate compression tests are still run but `-SKIP-' is
printed instead of `PASSED' if the zlib library was not
detected at configuration time. The tests check that the
compression layer (H5Z) is correctly bypassed.

Most of these changes are because the `interface_initialize_g'
variable change from hbool_t to int. It's a one line change.
Changed the way the library is closed so we have more control
over the order the interfaces are shut down. Instead of
registering an atexit() function for every interface in some
haphazard order we just register one: H5_term_library() which
then calls the H5*_term_interface() functions in a
well-defined order.
If the library is closed and then reopened repeatedly by
calling H5close() and H5open() in a loop we only add one copy
of the library termination functions with atexit().
Termination is a two-step process in order to help detect
programming errors that would cause an infinite loop caused by
the termination of one interface waking up some other
previously terminated interface. The first step terminates
the interface and *marks it as unusable*. After all
interfaces are terminated then we mark them all as usable
again. The FUNC_ENTER() macro has been modified to return
failure or to dump core (depending on whether NDEBUG is
defined) if we try to call an interface while it's shutting
down.
./src/H5.c
The H5dont_atexit() function returns failure if it's called
more than once or if it's called too late. However, the error
stack is not automatically printed on failure because the
library might not be initialized yet
./test/chunk.c
./test/flush1.c
./test/flush2.c

Changed the extra cast for Win32 so we do floating point
division again -- it was just confusion about precedence and
associativity of casting and the C coercion rules. Removed
extra carriage returns inserted by broken operating system.
./src/H5Ffamily.c
Fixed an bug where H5F_fam_write() lowered the EOF marker for
one of the family members causing H5F_fam_read() to read
zeros.

Support library for test files. This isn't done yet but
Katie's contractions are ~10 minutes apart so I figured I
better back this stuff up just in case I'm not here next
week...
Eventually all test files will understand HDF5_DRIVER to name
the low level file driver and parameters so we can easily test
various drivers. They will also understand HDF5_PREFIX to
prepend to the beginning of file names which is necessary for
testing ROMIO with various drivers. Also, the cleanup function
will know how to use the file name prefix and will understand
different file driver naming schemes like file families. I'm
not sure they'll understand the `gsf:' type prefixes yet.
Note, the external test is completely commented out because
I'm in the middle of modifying it. It will still compile and
run but it doesn't test anything at the moment.

Added more configuration stuff for the Win32 environment. Removed all
the #ifdef WIN32 from the source and replaced them with OS-independent
stuff. Specifics follow:
Check for non-Posix.1 `st_blocks' field in `struct stat' which is used
by the big file test to decide if the file system supports holes. If
the st_blocks field isn't present then we just skip the test.
Configure checks for <io.h> <sys/resource.h> <sys/time.h> and
<winsock.h> and defines HAVE_IO_H, HAVE_SYS_RESOURCE_H,
HAVE_SYS_TIME_H and HAVE_WINSOCK_H when they're found.
Configure checks whether both <sys/time.h> and <time.h> can be
included and defines SYS_TIME_WITH_TIME if so. Otherwise include only
<sys/time.h> or <time.h> even if both exist.
Configure checks sizeof(__int64) and defines SIZEOF___INT64 to the
result or to zero if __int64 isn't defined. The source uses `long
long' in preference to `__int64'.
Removed null WIN32 definition for `inline' since such a definition
already exists in H5config.h
Protected gettimeofday() calls in debugging code with
HAVE_GETTIMEOFDAY instead of WIN32.

Removed #include of system files from library source files and
consolodated them into H5private.h where they're protected by various
configuration macros (most of them were duplicated there already
anyway).

./test/shtype.c
./test/unlink.c
Protected system #include's with #ifdef's from H5config.h.
Undefined NDEBUG since some of the tests rely on assert() to check
return values.
Removed WIN32 definitions for __unused__ since this can be controlled
by the definition of HAVE_ATTRIBUTE in H5config.h
./test/testhdf5.h
Removed the CLEAN_CMD definition because we no longer use it.
Albert's cleanup() functions replaced it.
./test/fillval.c
Initialized auto hid_t variables to fix warnings in error recovery
code when data flow analysis is turned on in compilers.
./test/h5tools.c
Initialized an auto variable to fix a compiler warning.
./test/chunk.c
./test/ragged.c
The WIN32 had some unsigned variables changed to signed because the
compiler generates warnings when coercing unsigned to double(?). I
changed them back to unsigned because they really are unsigned
quantities. If this the change was just to shut up extraneous warnings
then perhaps a compiler flag can do the same; otherwise if the
compiler generates bad code then we should supply a patch file instead
messing up source code with bug work-arounds.
./src/H5detect.c
Protected system #include's with #ifdef's from H5config.h thereby
removing a WIN32.
If getpwuid() doesn't exist (HAVE_GETPWUID) then we assume that
`struct passwd' doesn't exist either (we don't really need it in that
case).
The H5T_NATIVE_LLONG and H5T_NATIVE_ULLONG are defined in terms of
`long long' or else `__int64' or else `long' depending on what's
available.
./src/H5Flow.c
./src/H5Ofill.c
Added __unused__ to some function arguments that aren't used when
assertions are turned off.
./src/H5V.c
Changed an auto variable name in some hand-inlined code to get rid of
a warning about the variable shadowing a previous auto.

The number of slots in the raw data cache can be queried or
set with H5Pget/set_cache(), which now take an extra argument.
The default number of slots is 521 and the default maximum
size is 1MB.
./src/H5Fistore.c
./src/H5Fprivate.h
Finished optimizations. The cache is now a hash and a linked
list instead of an array. The cpu time on my machine for
H5F_istore_lock() has been cut by 60% and H5F_istore_unlock() by
35%.
----------------------
./MANIFEST
Removed duplicate Ragged.html
./doc/src/Glossary.html
Changed 1.0 to 1.2 since 1.0 is the current development
branch, 1.1 will be development after beta release, and 1.2
will be the first complete release (see Version.html).
./test/dsets.c
./test/tstab.c
Added more tests.

file, a potential security problem.
./src/H5T.c
./src/H5Tpublic.h
Added new data types for hdf5 types: H5T_NATIVE_HSIZE,
H5T_NATIVE_HSSIZE, H5T_NATIVE_HERR, and H5T_NATIVE_HBOOL. I
did not add H5T_NATIVE_HID since I couldn't think of a reason
that it would be stored in a file anyway.
----------------------
./src/H5Fistore.c
Fixed a bug that caused the wrong number of chunk offsets to
be read or written from the file.
./src/H5Z.c
Fixed a memory bug.
./test/dtypes.c

./src/H5Shyper.c
Fixed a bad call to malloc() that didn't allocate enough
memory. Reordered a comparison to eliminate an array bounds
read error.
