Fix problems with 'check-vfd' target, that were [mostly] introduced with
the recent "unique, but sharable" ISOHM optimization.
The problems were mostly with using the 'core' VFD, so the
H5Pset_fapl_core() API call was changed to re-open existing files (therefore
operating more list the sec2, stdio, etc. VFDs). This allows many more of
the tests to run using the 'core' VFD, so those were enabled also.
Tested on:
Linux/64 2.6 (chicago2) w/check-vfd
Change H5[D|G|T]<foo>_expand() "temporary" API routines to
H5[D|G|T]<foo>2() "versioned" routines. Also added
H5[D|G|T](create|commit)_anon() routines to continue to allow "anonymous"
objects to be created in a file.

Eliminate storing # of links in "link info" message, regenerate it
when the object is opened instead.
Tested on:
FreeBSD/32 6.2 (duty)
Mac OS X/32 10.4.8 (amazon)
Move ref. count of # of links to an object out of the object header's
prefix and make it a header message instead (since it's a "rare" occurence),
eliminating some more space for each object in the file.
Inserting this "ref. count" message exposed a flaw in the library's
mechanism for locating a message to promote to another chunk and replace
with a continuation message, which required some additional work to fix.
It's still not completely robust, but it's working for more cases now and
detects failures robustly.
Reduced the minimum size of an object header chunk to just enough to
contain a header message prefix and continuation message.
Tested on:
FreeBSD/32 6.2 (duty)
Move "creation order tracked" flag from "group info" to "link info"
object header message and make the "max. creation order value" optional in the
"link info", if the creation order for links is not tracked.
Also, get rid of unused "index names" flag - names are always indexed
currently.
Tested on:
FreeBSD/32 6.2 (duty)
Eliminate message count from new version of object header prefix -
it can be computed when the header is loaded and the table of messages is
built.
Tested on:

Move attribute tracking information out of object header prefix and
make it into a message that is inserted only when attributes are present on
the object.
Tested on:
FreeBSD/32 6.2 (duty)
The main purpose of this checkin was to eliminate the
space used for tracking creation time indices when there is no way they
can be used (i.e. attributes can't be shared in the file and the user hasn't
turned on attribute creation tracking), however there were some other minor
changes which crept in:
- Fix a cache locking deadlock when a shared attribute and one of its
components end up in the same fractal heap direct block.
(This is fixed the "slow" way for right now, until John has time
to add support for readers/writer locking to the cache.
- Optimize attribute copying when a copy will be kept during a v2 B-tree
search.
- When freeing a block on disk, attempt to merge it with the metadata
and "small data" aggregators.

Add fields for tracking attributes on objects to object header prefix,
when using the latest version of the format.
Reduce size used to store type of header message from 2 bytes to 1. (If we
have >256 message types, we probably have a different problem... :-)
Also, add "birth" time for object (i.e. creation time) [named to align
with similar fields in file systems]
Correct bug in H5Gget_objinfo() - retrieve the ctime field from object info,
instead of the mtime field.
Tested on:

When using the latest version of the file format, move the "modification
time" information into the object header prefix, which is more efficient.
Also add "access time" and "change time" (for metadata) fields, all of which
take about the same space as the previous modification time header message.
Tested on:

Bug fix (related to 544)
Description:
h5_get_file_size() was coded to return 0 if failed but
file size can be 0. Changed the failure return value to -1
which is allowed by the returned type of off_t which is a signed
type.
Also changed the checking code of the stat call to just == 0
since that is how it is defined.
Test:
Could test it in heping only. Both Sol and Copper failed to
compiled due to error in the Direct IO VFD code.
Further minor modifications to the file format for tracking links in groups.
This is tentatively the "final" file format for groups.
Tested on:
Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago2)
File format is not stable, don't keep files produced!
Description:
First stage of checkins modifying the format of groups to support creation
order. Implement "dense" storage for links in groups.
Try to clarify some of the symbols for the H5L API.
Add the H5Pset_latest_format() flag for FAPLs, to choose to use the newest
file format options (including "dense" link storage in groups)
Add the H5Pset_track_creation_order() flag for GCPLs, to enable creation
order tracking in groups (although no index on creation order yet).
Remove --enable-group-revision configure flag, as file format issues are
now handled in a backwardly/forwardly compatible way.
Clean up lots of compiler warnings and other minor formatting issues.

Users can create external links using H5L_create_external(). These links
point to an object in another HDF5 file. Users can alter the behavior of
external links or create new kinds of links by registering callbacks
using the H5L interface.
Added tests, tools support, etc.
Also a number of other, minor changes have been made (some restructuring of
the H5L interface, for instance).
Additional documentation and examples are forthcoming.
"make check-vfd" will now run all tests in the test directory with different
file drivers (at least, all of those tests that use the testing framework's
FAPL). Tests that fail will be skipped.
This is not a perfect fix, but is better than nothing.
Along with this change, check-vfd should be added to the Daily Tests.
Feature
Description:
Revised Link APIs.
Solution:
New link APIs use H5L*
H5*create_expand do not create links to the objects created; this must
be done manually with H5Llink.
Added APIs to link an object given its ID (H5Llink), to copy links (H5Lcopy),
and changed creation APIs (H5Lcreate_hard and H5Lcreate_soft) and query
API (H5Lget_linkinfo instead of H5Gget_objinfo).
All old APIs are still supported in H5Gdeprec.c .
Platforms tested:
sol, mir, copper
Misc. update:
Forgot to update MANIFEST and release docs. Will do after checkin.
Code cleanup
Description:
Trim trailing whitespace in Makefile.am and C/C++ source files to make
diffing changes easier.
Platforms tested:
None necessary, whitespace only change
Anti-feature
Description:

Linux 2.4/64 (mir) w/C++ & Fortran
Solaris 2.9 (shanti)
"Hide" file format changes (for now)
Description:
Add ifdef's (controlled by the --enable-group-revision configure flag)
to disable group revision changes to the file format, in order to allow alpha
release to go ahead without releasing an unsupported version into the wild.

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...
Platforms tested:
h5committested and maybe another dozen configurations.... :-)
Code cleanup
Description:
Trim trailing whitespace, which is making 'diff'ing the two branches
difficult.
Solution:
Ran this script in each directory:
foreach f (*.[ch] *.cpp)
sed 's/[[:blank:]]*$//' $f > sed.out && mv sed.out $f
end
Platforms tested:
FreeBSD 4.11 (sleipnir)
Too minor to require h5committest
Purpose:
Bug Fix
Description:
Trying to create the root group or the working group ("/" or ".") fakes out
HDF5 so that it neither creates a group nor returns an error.
Solution:
H5G_namei now throws an error if it was supposed to insert but didn't.
Platforms tested:
sleipnir, Visual Studio 7 (very minor change)
Misc. update:
Update
Description:
Updated the Copyright statement

modules still compile)
Misc. update:
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
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)
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.)
