Bug fixes and code cleanup
Description:
Lots of changes here:
- Fixed bug #691 - when shared datatypes are used in attributes they
are incorrectly copied into the attribute instead of referring
the the named datatype in the file. This required bumping the
version of the attribute message. The new version of the attribute
message is only written out when a shared datatype is used in
the attribute. [Also, this format change made the size of the
attribute smaller.]
- Added information to attribute debugging routine so that shared
datatypes are displayed correctly with the h5debug tool.
- Refactored the H5O* routines to extract code that was common to
several routines into subroutines to call.
- Added 'link' method for H5O message sub-classes, which increments
the link count on shared objects when a message is created which
shares them.
- Corrected [unreported] bug where the link count was not being
decremented on the shared object when a object header message
with a reference to that object was deleted from the file.
- Reduced size of shared message from 49 bytes (which was incorrect
anyway and should have been 48 bytes) to 10 bytes, which required
bumping the version of "shared" messages.
- Refactored some of the shared datatype routines to allow for easier
queries of "committedness" internally to the library and also
added routine to easily increment/decrement the reference count of
a shared datatype.

Code cleanup
Description:
Limit the scope on more function prototypes/macros/typedefs.
Platforms tested:
FreeBSD 4.8 (sleipnir)
h5committest not necessary.
New feature
Description:
Track changes in the internal metadata API with clearing the metadata
dirty flag without flushing object.
Added ability to delete an object header in the file and restore all the
space referenced by various header messages.
Platforms tested:
FreeBSD 4.8 (sleipnir) w/C++
Linux 2.4 (burrwhite) w/FORTRAN
Solaris 2.7 (arabica) w/FORTRAN
IRIX64 6.5 (modi4) w/parallel & FORTRAN

Code cleanup
Description:
Clean up miscellaneous warnings which have crept into the code.
Fix "_POSIX_C_SOURCE not defined" warning on FreeBSD.
Adjust gcc compiler flags to be more concise for production mode.
Refactor the H5O code so that there is a stronger boundary between code
in the H5O package and code in the library which just calls H5O routines.
Platforms tested:
Tested h5committest {arabica (fortran), eirene (fortran, C++)
modi4 (parallel, fortran)}
FreeBSD 4.7 (sleipnir) serial & parallel and gcc 2.95.4 & gcc 3.2.2
Misc. update:
Update MANIFEST if you add or remove any file.
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
Code cleanup/new feature.
Description:
Split FUNC_LEAVE into API and non-API specific versions. This allows a
solution to compiling this branch with C++, as well as reducing the size
of the binaries produced.
Platforms tested:
FreeBSD 4.7 (sleipnir) w/serial, parallel (including MPE) & thread-safe
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.
Platforms tested:
Tested h5committest {arabica (fortran), eirene (fortran, C++)
modi4 (parallel, fortran)}
Other platforms/configurations tested?
FreeBSD 4.7 (sleipnir) serial & parallel
Solaris 2.6 (baldric) serial
Code cleanup
Description:
Changed the last HRETURN* statements in the FUNC_ENTER macros into HGOTO*
macros, which reduces the size of the library binary in certain
configurations by another 10%
Platforms tested:
FreeBSD 4.6 (sleipnir) serial & parallel, IRIX64 6.5 (modi4) serial &
parallel
Code cleanup
Description:
Change most (all?) HRETURN_ERROR macros to HGOTO_ERROR macros, along with
HRETURN macros to HGOTO_DONE macros. This unifies the error return path
from functions and reduces the size of the library by up to 10% on some
platforms.
Additionally, I improved a lot of the error cleanup code in many routines.
Platforms tested:
FreeBSD 4.6 (sleipnir) serial & parallel and IRIX64 6.5 (modi4) serial &
parallel.
Code cleanup
Description:
Broke the FUNC_ENTER macro into several macros, with more specialized
uses (which followup mail will describe). This was designed to move
most/all of the checks which could be done at compile time to that point,
instead of needlessly performing them (over & over :-) at run-time.
This reduces the library's size (and thus staticly linked binaries) and
has a minor speedup effect also.
Platforms tested:
IRIX64 6.5 (modi4) with parallel & FORTRAN enabled, and additional testing
on FreeBSD and Solaris immediately after the checkin.
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)
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)
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.

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

Changed the extra cast for Win32 so we do floating point

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 36 more integer hardware conversion functions to the
type conversion table for conversions to/from `long long' and
`unsigned long long'. The `long long' names will be changed
shortly to make them portable to Win32.
Changed H5T_init() to H5T_native_open() and added an
H5T_native_close() to open and close the predefined native
data types.
Increased the initial size of the type conversion table from
64 to 128 entries.
Reordered the 90 new integer conversion functions so the names
that are printed favor `int' over `short' or `long' when two
of them are the same.
./test/dtypes.c
Added hardware and software integer conversion tests for the
56 functions I added recently but not the additional 36
checked in this time. That will come next.
Call H5close() after each test so type conversion statistics
are easier to follow. Try this: $ HDF5_DEBUG=t ./dtypes
Added more debugging output for when things go wrong.

Changed memory allocation functions so they fail instead of
dumping core. The `x' was removed from the name to remind us
of that: H5MM_xmalloc() -> H5MM_malloc(), etc.
H5MM_calloc() takes one argument like H5MM_malloc() instead of
two like calloc() because we almost always called it with `1'
for one of the arguments anyway. The only difference between
the two functions is that H5MM_calloc() returns memory which
is initialized to zero.
./src/H5Gent.c
./src/H5Gprivate.h
Removed H5G_ent_calloc() since it wasn't used.
./src/H5Fistore.c
Fixed a bug found by Albert. Thanks, Albert! This fix

Updated to work with new internal H5T functions. Fixed some
data type memory leaks during error recovery.
./src/H5Dprivate.h
Added H5D_typeof() similar to H5D_entof() that returns a
pointer directly to the dataset's type. This is used by
H5Tcopy() when invoked on a dataset (see below).
./src/H5Epublic.h
Fixed typos in H5E_BEGIN_TRY and H5E_END_TRY macros.

An object header message can now be a pointer to a message in
some other object header. The pointer is to the first message
of the appropriate type in the other object header and hard
link counts are maintained automatically to prevent dangling

also supported although nothing actually uses it.

./src/H5Tpublic.h
Added named data types and changed the functionality of some
API functions as follows:
* The term `read-only' means that a type handle cannot be
modified with functions like H5Tset_*() or H5Tinsert().
* The term `immutable' means the same as `read-only' with the
added restriction that H5Tclose() cannot be called for the
type. A transient type is made immutable by calling
H5Tlock().
* Handles to named types are always read-only.
* Handles to predefined types are immutable.
* A transient type can be converted to a named type by calling
H5Tcommit(). This function will fail if the type is already
named or is immutable.
* The API function H5Tcommitted() returns an indication of
whether a data type has been commited (or is named). If
H5Tcommitted() returns TRUE for a data type obtained by
calling H5Dget_type() on a dataset, then the dataset is
using a shared data type.
* H5Topen() returns a handle to a named type.
* H5Tcopy() always returns a handle to a modifiable transient
type even when invoked on a named type. Also, when invoked
on a dataset it returns a modifiable transient type which is
a copy of the dataset's data type.
* Using a named data type in the call to H5Dcreate() causes
the dataset object header to point to the named data type,
but using a transient type causes the type to be copied into
the dataset's object header.
* The data type returned from H5Dget_type() is a named data
type or a read-only transient data type depending on whether
the dataset points to a named data type. The old behavior,
to return a modifiable transient type, is accomplished by
overloading H5Tcopy() to operate on datasets (see above).
* H5Tshare(), H5Tunshare(), and H5Tis_shared() have been
removed from the API.
The following features were *not* implemented because they
need more discussion:
* A named data type can be opened by applying H5Topen() to a
dataset in which case the data type is the data type of the
dataset (or the data type to which the dataset points if the
dataset has a shared data type).
* A named data type can have attributes like groups or
datasets.
* The members of a compound data type can point to named data
types.

Anything having to do with the size of a dataset now uses the
types `hsize_t' and `hssize_t' which must be the same size and
at least as large as `size_t'. This isn't fully tested yet,
so hsize_t and hssize_t are defined as size_t and ssize_t in
H5public.h. Setting them to larger values will trip up gcc
versions less than 2.8.1 on x86 platforms.
Documented unused function formals with `__unused__' before
the formal name. This also has the effect of supressing
warning messages for gcc since it's defined to be
`__attribute__((unused))' in the H5private.h file.
./src/debug.c

./config/linux
./src/H5HL.c
./src/H5HLprivate.h
./src/H5MF.c
./src/H5MFprivate.h
Added `-DH5HL_DEBUG -DH5MF_DEBUG' to the debug list.
./html/H5.format.html
Updated shared object message information.
./src/H5D.c
Datasets can now share data types.
./src/H5F.c
Updated a comment that referred to H5ACC_WRITE.
./src/H5HG.c
./src/H5HGprivate.h
Moved a few things around. Made debugging better so you can
now give a collection address to ./src/debug and it shows some
useful stuff.

The H5Tshare() function allows the user to give the library
hints about how a data type will be used.

./configure.in
./config/BlankForm [NEW]

./config/irix64
./config/linux
./config/powerpc-ibm-aix4.2.1.0

./config/solaris2.5
Cleaned up lots of configuration stuff and made the site
configuration files lots easier and more uniform. To make a
new file grab the BlankForm and modify it.
By default, debugging is turned on for most packages. Within
a package one can use `#ifdef H5AC_DEBUG' to wrap debugging
code. Other options are:
--enable-debug
--enable-debug=yes
The default, most but not all packages.
--disable-debug
--enable-debug=no
--enable-debug=none
The symbol NDEBUG is defined and none of the package
debug symbols.
--enable-debug=all
Debugging is turned on for all packages. This might
produce lots of output.
--enable-debug=g,d
Debugging is turned on for H5G and H5D.
A compile mode is also now supported
--enable-production
--enable-production=yes
The library is compiled with optimizations turned on.
The compiler flags are augmented by adding PROD_CFLAGS
and PROD_CPPFLAGS which are defined in the site config
file.
--disable-production
--enable-production=no
The default. The library is compiled for development
by including DEBUG_CFLAGS and DEBUG_CPPFLAGS defined in
the site config file. This is usually just `-g'.
--enable-production=profile
--enable-production=pg
Builds a library for profiling by including the flags
from PROFILE_CFLAGS and PROFILE_CPPFLAGS defined in the
site config file. This is usullay just `-pg' but it
could include optimization flags as well depending on
the type of profile one wants.
In summary, configure by saying `./configure' and you'll get a
development version of the library. Configure by saying
`./configure --enable-production --disable-debug' and you'll
get a production version with no debugging code.

./src/H5D.c
./src/H5T.c
./src/H5Tprivate.h
Fixed a bug found by Kevin Powell regarding preservation of
existing data during a read or write when the source and

The application can now turn on/off the part of the I/O
pipeline that deals with preservation of initialized data.
The default is off since this will be the usual case and
turning it on slows down the pipe. Use H5Pset_preserve() and
H5Pget_preserve().
./src/H5Fistore.c

chunked storage.

./src/H5Odtype.c
Fixed a failing assert() wrt reading compound types (not
present in hdf5-1.0.0a).
while he is visiting LLNL. I changed the default creation template
offset and length to 4. Will fix the problem later.

Added `-woff 1196' to get rid of errors about __vfork() being
implicitly defined in a system header file.
./src/H5B.c
Fixed a stack alignment problem.
----------------------
./config/freebsd2.2.1
./config/linux
Added -UH5O_DEBUG to the debug flags. Turn this on to get
lots of lines on stderr to show what objects are opened and
closed.
./src/H5C.o
./src/H5Cpublic.h
./test/dsets.c

./src/H5F.c
./src/H5Fprivate.h
The file OID can be closed before other OID's.
./src/H5Flow.c
H5F_addr_defined() is a macro in this file.
./src/H5G.c
./src/H5Gpublic.h
./test/tstab.c
A current working group cannot be deleted.
./src/H5Gent.c
./src/H5Gpkg.h
Removed unused functionality.
./src/H5public.h
Includes <sys/types.h> for size_t.
Removed the interface initialization argument from
FUNC_ENTER() and made it a locally-defined preprocessor
symbol, INTERFACE_INIT.
Changed `offset' to `address' and `length' to `size' in
documentation so it's more consistent. `Offset' still appears
occassionally when it refers to a byte offset within some
other data structure.
Moved interface termination function prototypes from public
header files to .c files and made them static.
./src/H5.c
./src/H5public.h
Added H5init() because it's possible that the predefined data
types are not initialized. This happens only if the first
call to the hdf5 library passes a predefined data type symbol
as an argument. There should be some way to fix this...
./src/H5A.c
./src/H5Aprivate.h
./src/H5Apublic.h
The free_func returns SUCCEED or FAIL, although the return
value is ignored by H5A. This is so we can use the various
H5*_close() functions to free things.
H5Ainc_ref() and H5Adec_ref() are no longer public. Many of
the other atom functions should also be made private, but I'll
save that for later...
Added additional template groups called H5_TEMPLATE_0 through
H5_TEMPLATE_7 that are used by the various template
subclasses.
Increased the number of bits used for atom groups to prevent
negative atoms.
./src/H5AC.c
./src/H5ACprivate.h
Changed H5AC_new() to H5AC_create() to make names more consistent.
./src/H5B.c
./src/H5Bprivate.h
Changed H5B_new() to H5B_create() to make names more consistent.
./src/H5C.c
./src/H5Cprivate.h
./src/H5Cpublic.h
Now supports multiple subclasses of templates, although it's
done with big switch statements. The default values for
templates are defined in the source file to which that
template belongs. This got rid of lots of needless
preprocessor constants.
Added H5Ccreate() to create a new template. Changed
H5C_release() to H5Cclose() to make the naming more
consistent.
./src/H5D.c
./src/H5Dprivate.h
./src/H5Dpublic.h
Enhanced to use the new dataset interface, and uses the enhanced
data type and data space interfaces, which haven't been
completely implemented. The dataset interface doesn't handle
non-contiguous storage, compression, or data type and space
conversions yet.
./src/H5F.c
./src/H5Fprivate.h
./src/H5Fpublic.h
Removed H5Fflush() since just calls H5F_flush(), which doesn't
do what the user would probably think it does, namely, flush
everything. It only flushes those things sitting in the H5AC
cache and the boot block.
Changed the `file_create_parms' field of H5F_low_t to just
`create_parms' since the `file' part is obvious.
./src/H5Fistore.c
Added some support for external files. Mostly just in the
file format and not supported much by the library yet. I need
to finish some dataset functions first.
Changed H5F_istore_new() to H5F_istore_create() to make names
more uniform across packages.
./src/H5Flow.c
Flushing a file causes the file to be physically extended to
the logical eof. This prevents H5F_open() from thinking a
file has been truncated. Most of the time the file will
already be that large, and when it isn't Unix will often just
allocate the final block anyway.
./src/H5G.c
./src/H5Gent.c
./src/H5Gnode.c
./src/H5Gpkg.h
./src/H5Gprivate.h
./src/H5Gstab.c
Removed H5G_basename()
Removed (temporarily) data type information from symbol table
entries and renamed H5G_CACHED_SDATA to H5G_CACHED_SDSPACE to
reflect that it's a simple data space and has nothing to do
with raw data.
Changed H5G_node_new() to H5G_node_create() and H5G_stab_new()
to H5G_stab_create() to make names more uniform across
packages.
Fixed an undefined address bug that happens when H5G_node_debug()
program doesn't pass enough info to H5G_node_load().
./src/H5H.c
./src/H5Hprivate.h
Changed H5H_new() to H5H_create() to make the names more
uniform across packages.
./src/H5M.c
./src/H5Mprivate.h
./src/H5Mpublic.h
Nulled all the create functions. Most of the other callbacks
are to public functions. Removed H5Mcreate().
Changed hobjtype_t to group_t since it has to be the same
thing anyway.
./src/H5O.c
./src/H5Oprivate.h
./src/H5Osdim.c
./src/H5Osdtyp.c
Changed H5O_SIM_DIM to H5O_SDSPACE (simple data space) since
`simple data space' is its official name, not `simple
dimensions'. Will eventually add H5O_CDSPACE for comples data
spaces. Changed _sim_dim_ to _dspace_.
Replaced H5O_SIM_DTYPE and the compound data type messages
with a single H5O_DTYPE message. Changed _sim_dtype_ to _dtype_.
Changed H5O_STD_STORE to H5O_CSTORE (contiguous storage) since
contiguous storage is not necessarily standard. Changed
_std_store_ to _cstore_ in H5Ocstore.c
Added the H5O_EFL (external file list) message.
Changed H5O_new() to H5O_create() to make names more uniform
across packages.
./src/H5Oefl.c NEW
External file list message for specifying which non-hdf5 files
contain raw data for a dataset.
./src/H5P.c
./src/H5Pprivate.h
./src/H5Ppublic.h
Renamed and moved data structures to make the names conform to
our naming scheme.
./src/H5T.c
./src/H5Tprivate.h
./src/H5Tpublic.h
./src/H5Tpkg.h NEW
Data structures redesigned to be more flexible. The interface
was redesigned to make it more regular and to make some names
more uniform across packages.
./src/H5detect.c
Output was changed to produce a file that conforms to the hdf5
coding standard.
./src/Makefile.in
Generates H5Tinit.c by running H5detect.
./src/debug.c
Moved command argument processing.
./src/Makefile.in
Added H5Ffamily.c and H5Fsplit.c
./src/H5B.c
./src/H5Bprivate.h
./src/H5Gnode.c
Added `const' to sublass arguments.
./src/H5F.c

Make sure file buffers get flushed during a call to
H5Fflush(). Check for overflow in address encoding and decoding.
./src/H5Ffam.c
./src/H5Fprivate.c
./test/istore.c
Implementation of file families so 32-bit machines can access
64-bit files.
./src/H5Oprivate.h
Removed H5O_NO_ADDR constant.
./config/freebsd2.2.1
./config/linux
Added -DH5G_DEBUG and -DH5F_DEBUG to the list of debugging flags.
./html/H5.format.html

./test/tstab.c
Lots of changes caused by generalizing addresses. The haddr_t
is now a struct, so you can no longer perform arithmetic on
it. But since it's small, simple, and often used, storage is
allocated like with an integer. But we always pass them
around by reference. That is, when using an address in
another struct, allocate space:
struct my_struct {
char *name;
haddr_t address;
} x;
But when passing it to a function, pass by reference:
H5F_addr_print (stderr, &(x.address));
Addresses should be initialized with
H5F_addr_undef (&(x.address));
Functions for operating on addresses are in H5Flow.c and begin
with H5F_addr_... Functions never return haddr_t or haddr_t*;
they always pass them through arguments instead. A function
that returns an address through an argument does so with its
last argument and it is marked with `/*out*/'. Calls to such
functions also mark output-only arguments with `/*out*/'
./src/H5Fsplit.c (new)
A two-member family where all meta data goes in the first
member and all raw data goes in the second member.

extend the file to allocate more memory.
./src/H5E.c
./src/H5Epublic.c
Added the error H5E_TRUNCATED to be reported when the file is
shorter than the length recorded in the boot block.
./src/H5F.c
Added H5F_locate_signature() so we only do it in one place
now.
./INSTALL
./INSTALL_MAINT
Just a couple clarifications.

./html/storage.html
Documents how external files work.
./test/hyperslab.c

These files came from the old H5*proto.h files.

Removed. Now generated automatically from Makefile.in by
running configure.

Fixed include files. Moved some things from old headers into
these files.

./src/H5Aprivate.h
./src/H5Bprivate.h
./src/H5Cprivate.h
./src/H5Dprivate.h

./src/H5Tprivate.h
./src/H5private.h
./src/debug.c
Fixed include files.
./src/hdf5.h
This is now the top-level *PUBLIC* include file. It should
never appear in the library *.c files.
We sort the cache before a complete flush because it might be
more efficient to write things back to disk in order of
increasing address. If you want the old way then undef the
SORT_BY_ADDR constant at the top of H5AC.c I haven't
determined which systems and I/O libraries this helps or
hurts. (This is currently off because of a bug I need to track
down that causes qsort() to run for a really long time).
./src/H5B.c
Fixed a couple more bugs.
./src/H5Eprivate.h
./src/H5Eproto.h
Added major H5E_DIRECTORY and minor H5E_EXISTS, H5E_COMPLEN.
./src/H5G.c
Added directory-aware functions.
The heap and B-tree are created when a directory is created
instead of when the first symbol is added. This simplifies
symbol table entry caching for the directory since the cached
value never changes now.
./src/H5Gnode.c
./src/H5Gprivate.h
Fine tuned the B-tree K values for symbol tables assuming an
average number of symbols is about 100 per directory. The
tuning minimizes storage space.
Fixed a return value in H5G_node_cmp().
./src/H5H.c
./src/H5Hprivate.h
Moved some macros the the header file.
./src/H5O.c
./src/H5Ocont.c
./src/H5Onull.c
./src/H5Ostab.c
Changed the arguments for the decode method for messages. The
second argument is the raw message size.
Added a class variable for native message size.
Added H5O_reset() to free memory used internally by a message.
./src/H5Oname.c NEW
./src/H5Oprivate.h
./src/Makefile
The object name message.
./src/hdf5port.h
Added defn for HDstrdup()
Renamed H5AC_find() to H5AC_find_f() which is invoked from the
H5AC_find() macro.
Changed HASH() to H5AC_HASH().
./src/H5ACprivate.h
Increased the number of cache slots from 1033 to 10330 to see
how it affects performance. This should probably be
changeable on a per-file basis.
./src/H5B.c
Fixed some bugs now that symbol tables are actually using the
stuff.
Improved debugging a little.
Fixed uninitialized memory appearing in the file.
./src/H5D.c
Changed a FUNC_ENTER() argument from H5Dset_info to H5Dwrite.
./src/H5F.c
Plugged a memory leak in H5F_dest().
./src/H5G.c
./src/H5Gprivate.h
Many of these functions take a symbol table entry which
describes the symbol table rather than just the symbol table
address.
Moved some functions to make room for the ones that understand
directory names:
H5G_new() -> H5G_stab_new()
H5G_find() -> H5G_stab_find()
H5G_modify() -> H5G_stab_modify()
H5G_insert() -> H5G_stab_insert()
H5G_list() -> H5G_stab_list()
./src/H5Gnode.c
Added more assertions.
Zero new memory so junk doesn't appear in the data file. This
is a problem when one tries to declassify a classified data
file.
H5G_node_debug() can take an extra argument which is the
address of the heap for the symbol table. If supplied, the
symbol names are printed along with the heap offsets.
./src/H5H.c
./src/H5Hprivate.h
Fixed a bug with the free blocks by forcing things to align on
even boundaries. It's still possible to lose heap memory if
the hole is smaller than the free list header. The
alternative is to align heap objects on 12 or 20 byte
boundaries, but this tends to waste to much space.
Zero new memory like with H5Gnode.c.
Fixed a "mispeling" of NDEBUG.
./src/H5Ocont.c
./src/H5Onull.c
Added the pablo mask defn.
./src/H5Ostab.c
Added the pablo mask defn.
Fixed a read from uninitialized memory.
./src/H5Oprivate.h
Tuned some parameters to see how they affect performance.
./src/debug.c
An optional third argument can be supplied which is the
address of a heap to use to display names in a symbol table.
./src/hdf5pabl.h
Changed `int' to `intn'.
./src/H5ACprivate.h
./src/H5ACproto.h
./src/H5Bproto.h
./src/H5Gproto.h
./src/H5Hproto.h
./src/H5MFprivate.h
./src/H5MFproto.h
./src/H5MM.c
./src/H5MMprivate.h
./src/H5MMproto.h
Changed my e-mail address.
./src/H5O.c NEW
./src/H5Onull.c NEW
./src/H5Ocont. NEW
./src/H5Ostab.c NEW
New functions for dealing with object headers. The H5O.c is
the generic stuff, and each particular message has a source
file for the specific stuff.
Use ./src/H5Ostab.c as a model for implementing other messages.
./src/Makefile
./src/test/Makefile
Added new files
./src/debug.c
Added debugging calls for object headers.
./src/H5B.c
./src/H5Bprivate.h
./src/H5Gnode.c
./src/H5MF.c
Changed my e-mail address.
Improved error handling.
./src/H5Eprivate.h
./src/H5Eproto.h
Added more error symbols
./src/H5F.c
Changed my e-mail address.
Used macros for sizeof offsets and lengths.
Added the interface initialization function to
H5F_block_read() and H5F_block_write().
Updated H5F_debug()
./src/H5Fprivate.h
Got rid of H5F_symbol_table_size(). Use H5G_SIZEOF_ENTRY()
instead.
Reformatted H5F_decode_offset() for readability.
./src/H5G.c
Changed my e-mail address.
Improved error handling.
Replaced not_implemented_yet__*() with real functions from
H5O.
./src/H5Gprivate.h
Changed `symtab' to `stab' to be consistent with other stuff.
./src/H5H.c
./src/H5Hprivate.h
Changed my e-mail address.
Improved error handling.
Added an extra argument to H5H_new() to indicate whether you
want a global heap or a local heap.
./src/hdf5gen.h
Added NELMTS()
Fixed FUNC_ENTER()
Rewrote FUNC_LEAVE() in terms of HRETURN().
./src/hdf5meta.h
Added `const' to the decode macros.
./src/hdf5pabl.h
Added PABLO_SAVE()
./test/testhdf5.c
./test/testhdf5.h
Added calls for object header testing.
./test/theap.c
Turned off some output.
