Add "use the latest format" support for dataspace object header encode/
decode routines and clean up format a bit for the latest format (new to 1.8.x
releases)
Remove storing 'perm' parameter for array datatypes in memory and the file,
and add test to make certain that if any user applications are attempting to
store them, we get some reports back. (Should be unlikely, since the RefMan
says that the parameter is not implemented and is unsupported).
Carry those changes into the tests, etc.
Clean up a bunch more compiler warnings.

Finish 'use the latest version of the format' changes to the datatype
object header message. Compound and enumerated types will now be encoded
more efficiently by packing the field names & member offsets better.

Add the "use the latest version of the format" support to datatype
messages. And a regression test to check that it's working.
Also, found that we have been over-allocating space for compound datatype
messages (when they have array datatypes or can use the latest version of the
format) and trimmed the size back.
Clean up datatype & dataspace encode/decode routines by having them
allocate & release "fake" file structures, which gets them out of needing to
"know" about the internals of file structures.
Other minor whitespace/formatting cleanups, etc.

New feature
Description:
Check in baseline for compact group revisions, which radically revises the
source code for managing groups and object headers.
WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!!
WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!!
This initiates the "unstable" phase of the 1.7.x branch, leading up
to the 1.8.0 release. Please test this code, but do _NOT_ keep files created
with it - the format will change again before the release and you will not
be able to read your old files!!!
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...

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... :-)

Code cleanup
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....

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".

Purpose:
Feature
Description:
Datatypes and groups now use H5FO "file object" code that was previously
only used by datasets. These objects will hold a file open if the file
is closed but they have not yet been closed. If these objects are unlinked
then relinked, they will not be destroyed. If they are opened twice (even
by two different names), both IDs will "see" changes made to the object
using the other ID.
When an object is opened using two different names (e.g., if a dataset was
opened under one name, then mounted and opened under its new name), calling
H5Iget_name() on a given hid_t will return the name used to open that hid_t,
not the current name of the object (this is a feature, and a change from the
previous behavior of datasets).
Solution:
Used H5FO code that was already in place for datasets. Broke H5D_t's, H5T_t's,
and H5G_t's into a "shared" struct and a private struct. The shared structs
(H5D_shared_t, etc.) hold the object's information and are used by all IDs
that point to a given object in the file. The private structs are pointed
to by the hid_t and contain the object's group entry information (including its
name) and a pointer to the shared struct for that object.
This changed the naming of structs throughout the library (e.g., datatype->size
is now datatype->shared->size). I added an updated H5Tinit.c to windows.zip.

Purpose: New feature
Description: New API H5Tencode and H5Tdecode. Given object ID, H5Tencode encodes object information into a binary form. H5Tdecode decode an object information in a binary form, reconstructs the object and return a new object ID.
Solution: Use object header functions H5O_dtype_decode and H5O_dtype_encode to
facilitate them. The encoded binary is exactly like object header information.
This is the first step checkin. Will check in H5Sencode and H5Sdecode later.
Platforms tested: h5committed and fuss.
Misc. update: will update release.txt after 2nd step checkin.

Code cleanup & minor optimization
Description:
Re-work the way interface initialization routines are specified in the
library to avoid the overhead of checking for them in routines where there is
no interface initialization routine. This cleans up warnings with gcc 3.4,

library's execution slightly.

Solution:
Had to add a new FUNC_ENTER_NOAPI_NOINIT_NOFUNC macro for those non-API

much easier when C99 is standard on all our supposed platforms, since it has a
__FUNC__ macro... )

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.

not shrink).

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.
Platforms tested:
Tested h5committest {arabica (fortran), eirene (fortran, C++)
modi4 (parallel, fortran)}
Other platforms/configurations tested?

Purpose:
Added 'ID to name' support
Description:
There is a new API function H5Iget_name
Most of the changes are on H5G.c , regarding the symbol table entry struct H5G_entry_t
which has 2 new fields 'name' and 'old_name'
A new private function was introduced H5G_ent_copy, that does a deep copy
between 2 symbol table entries
The test file is getname.c
Platforms tested:
windows 2000, Linux, Solaris
