WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!!
WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!!
Solution:
There's too many changes to really describe them all, but some of them
include:
- Stop abusing the H5G_entry_t structure and split it into two separate
structures for non-symbol table node use within the library: H5O_loc_t
for object locations in a file and H5G_name_t to store the path to
an opened object. H5G_entry_t is now only used for storing symbol
table entries on disk.
- Retire H5G_namei() in favor of a more general mechanism for traversing
group paths and issuing callbacks on objects located. This gets us out
of the business of hacking H5G_namei() for new features, generally.
- Revised H5O* routines to take a H5O_loc_t instead of H5G_entry_t
- Lots more...
Platforms tested:
h5committested and maybe another dozen configurations.... :-)
New feature
Description:
Add in baseline "object copy" code from Peter [in the form of a new API
routine: H5Gcopy()]. There's still some work to do (like handling variable-
length datatypes and possibly support for references) and it hasn't been tested
on mounted files yet, but the core functionality is there and working
correctly.
I've also got a set of patches to update the 1.6 branch with tweaks to
keep the branches mostly in sync, but Elena will kill me if I import them
before the 1.6.5 release is out... :-)

Description:
Merge back changes from "compact group" work that improve the
infrastructure of the library and may impact others. In this round of
merging, that includes:
- Move datatype allocation into single internal routine, instead of
duplicated code that was spread out in a dozen or so places.
- Clean up guts of object header routines (H5O_*) to allow for some of
the fancieroperations that need to be performed on groups, along with
some general improvements.
- Added a new error code
- Some minor cleanups in other code....

Misc. update:
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".

Description:
When dimension information is being stored in the storage layout message

Fix the storage layout message problem by revising file format to not store
dimension information, since it is already available in the dataspace.
Also revise the storage layout data structures to be more compartmentalized
for the information for contiguous, chunked and compact storage.

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.

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.

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.

Bug fix/Code cleanup/New Feature
Description:
Correct problems with writing fill-values to external storage and allocate
the data storage at the correct times.
Also, mostly straighten out the strange code which allocates and fills
raw data storage for datasets. Things are still a bit odd in that the
fill-values for chunked datasets are written when the space is allocated,
instead of in a separate routine, but there are two reasons for this:
it's inefficient (especially in parallel) to iterate through all the chunks
twice, and (more importantly) the space needed to store compressed chunks
isn't known until we've got a buffer of compressed fill-values ready to
write to the chunk.
Additionally, add in the H5D_SPACE_ALLOC_INCR and H5D_SPACE_ALLOC_DEFAULT
setting for the "space time", which incorporate the previous behavior of
the space allocation for chunked datasets.
The default settings for the different types of dataset storage are now
as follows:
Contiguous - Late
Chunked - Incremental
Compact - Early
This checkin also incorporates a change to the behavior of external data
storage in two ways - fill-values are _never_ written to external storage
(under the assumption that writing fill-values is triggered by allocating
space in an HDF5 file, and since space is not allocated in the file, the
fill-values should not be written) and external data files are now created
if they don't exist when data is written to them. The fill-value will
probably need to be revisited at some time in the future, this just seemed
like the safer course currently.
I think I cleaned up some compiler errors also, before getting bogged down
in the fixes for the space allocation and fill-values.
Platforms tested:
FreeBSD 4.6 (sleipnir) w/serial & parallel. Will be testing on IRIX64
6.5 (modi4) in serial & parallel shortly.

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.
Purpose:
New feature
Description:
Fill-value's behaviors for contiguous dataset have been redefined.
Basicly, dataset won't allocate space until it's necessary. Full details
are available at http://hdf.ncsa.uiuc.edu/RFC/Fill_Value, at this moment.
Platforms tested:
Linux 2.2.
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.
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.

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

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.

./src/H5config.h.in [REGENERATED]
Check for xdr_int() in libnsl required on Solaris when linking
with hdf4. It's found on the Irix system I tested which
complains that `-lnsl' didn't resolve any symbols. Oh well.
Fixed the order of searching for libdf and libmfhdf for hdf4
linking.

Check for compress() in libz in order to find older versions
of the library that will still work for hdf4. Added a
separate check for compress2() that hdf5 will use.

reinitializes global variables properly.

Changed MAX_SIZET, MAX_SSIZET, MAX_HSIZET, and MAX_HSSIZET to

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.
./src/H5private.h
Removed trailing carriage-returns inserted by broken operating
system ;-)

./test/th5s.h5 [NEW]
./test/th5s.c
Added a test to make sure that creating a data space with too
large a rank fails.
Added a test to make sure that reading a file that has a
dataset with a space with too large a rank fails. Actually,
this one is a little weird: the code that reads the data space
message assumes the space is scalar if the message cannot be
read. Fortunately the layout message fails also, preventing
the dataset from being opened. However, since the data type
message is still visible h5ls will report that the object is a
named data type.
./test/space_overflow.c [NEW]

./src/H5P.c

Check for ndims>H5S_MAX_RANK in API function calls, added
assert to internal functions.

gives up if the version numbers don't match, but in the future
the library could handle multiple versions of a message.

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
combined with the changes to memory allocation prevent the
library from failing an assertion if the application uses an
unreasonable size for chunks (like Alberts 10000x10000x4).
./src/H5MF.c

./src/H5Tconv.c
./src/H5detect.c
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.
./src/H5F.c
Closing a file with objects still open reports the file name
in the warning message. Removed unnecessary invalidation of
shared data types.
./src/H5Gent.c
./src/H5Gpkg.h
./src/H5Gprivate.h
Added `const' to some arguments.
./src/H5O.c
./src/H5Oprivate.h
./src/H5Oshared.c
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
pointers. The old global heap method of message sharing is
also supported although nothing actually uses it.

./src/H5Oshare.c
./src/H5Ostab.c
Changed the data type for the shared message info struct to
H5O_shared_t and added an extra initializer to the class
methods struct for the set_share method.
./src/H5Odtype.c
Added the ability to share data type messages by pointing to
other object headers.
./src/H5T.c
./src/H5Tpkg.h
./src/H5Tprivate.h
./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
./src/h5ls.c
If the file name contains a `%' then the file is opened as a
file family with H5P_DEFAULT for the file member access
property list.
./src/h5ls.c
The group name is optional, defaulting to `/'.
./src/hdf5.h
Added some missing public header files.
