Since these examples need to follow filesystem paths, the Makefiles need
to create directories in the examples directory; added this to the
Makefile.am.
Tested on Windows, mir, juniper
Tweak the library's new faster fletcher32 algorithm to always produce the
same checksum as the previous fletcher32 code in the fletcher32 I/O pipeline
filter and switch the filter to use the library's version of the algorithm.
Tested on:

Will test further after checkin...
Add a bunch more regression tests:
- Verify opening a fractal heap more than once works correctly
- Check that 0 & 1-sized object insertions are handled correctly
- Check that bad heap IDs are detected when attempting to read an
object
- Check that doubling tables with different parameter values are
working correctly
Add some more checks to the code to detect 0-sized object insertions and
bad heap IDs for reading.
Tested On:

- Migrate "direct block location" routine from H5HFman.c to H5HFdblock.c,
which is a more appropriate location
- Optimize performance of heap code by taking advantage of pinned
indirect blocks and use them without putting a metadata cache
protect/unprotect pair around them.
- Other minor compiler warning cleanups and optimizations...
Tested On:
FreeBSD/32 4.11 (sleipnir)
Linux/64 2.4 (mir)

Object header locations (H5O_loc_t's) can now "hold open" a file and
decrement its open object count when they close. This means that
locations (H5O_loc_t's and H5G_loc_t's) should always be freed.
Added more thorough tests to ensure that external files are closed.
flag, and pin an entry as it is inserted.
The objective is to avoid some function call overhead in fheap.
Also added matching test code in test/cache.c & test/cache_common.c
(also testpar/t_cache.c checked in separately by accident)
h5commit tested
Several changes, all mooshed together:
- Add support for "tiny" objects - which can be stored in the heap
ID itself, instead of in the heap data blocks.
- Flesh out support for compressed direct blocks, but comment it
out until John's got some metadata cache changes in place to
support it.
- Add support for applying I/O pipeline filters to 'huge' objects
- Refactor 'huge' object code to store information for 'huge' objects
directly in the heap ID, when there are I/O pipeline filters
applied to the heap (and the heap ID is large enough to hold the
information)
- Update h5debug tool to correctly handle 'huge' & 'tiny' objects.
- Misc. other code cleanups, etc.
Tested on:
FreeBSD/32 4.11 (sleipnir)
Linux/64 2.4 (mir)
Solaris/64 2.9 (shanti)
Allow the heap ID length to be chosen at heap creation time, to allow
for making heap IDs long enough to directly embed the file offset & length
of 'huge' objects in the heap ID (which allows them to be retrieved directly
from disk, instead of requiring them to be looked up in the B-tree that tracks
'huge' objects)
Tested on:
FreeBSD/32 4.11 (sleipnir)
Linux/64 2.4 (mir)
Solaris/64 9 (shanti)
Clean up a couple of compiler warnings in the 'huge' object code in the
library.
Add a bunch of 'huge' object regression tests
Tested on:
FreeBSD 4.11 (sleipnir)
Linux/64 2.4 (mir)
Solaris/64 2.9 (shanti)
Move metadata cache address rename for fractal heap indirect block
immediately after reallocing the storage on disk - to prevent another
routine in the library from confusing the cache by allocating more storage
and attempting to insert it in metadata cache at the old block's location.
Gotta like those monte carlo/random insert & delete tests, which exposed
this... :-)
Tested:
Solaris 2.9 (shanti)
Not failing on other machines
Initial revision to add support for "huge" objects in the heap (which are
actually stored directly in the file, but are tracked with v2 B-tree that is
accessed through heap header).
Testing:
FreeBSD 4.11 (sleipnir)
Linux/64 2.4 (mir)
Linux/32 2.4 (heping)

Daily test for ttsafe failed on several machines due to the changed error stack.
Solution:
Updated the source code to use new error stack.
Platforms tested:

More tweaks on fractal heap statistics, to better separate information
about managed objects from information about "huge" objects.
Also, clean up some compiler warnings, etc. on 64-bit platforms & Windows.
Platforms tested:
Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago)
Refactor fields in heap header to clean out information from dropped
features and also group related fields together more nicely.
Add fields to heap header for storing information about "huge" objects.
Platforms tested:
Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago)
Refactor fractal heap IDs to include "flag byte" as part of the ID. This
byte will be used for the heap ID format version as well as flags to indicate
whether the heap object is a "tiny"/normal/"huge" object (with storage
mechanisms optimized for each type of object).
Platforms tested:
Linux/32 2.4 (chicago)
Too minor to require h5committest
Clean up compiler warnings/failures in test/links.c, especially when
--disable-production flag used with --enable-group-revision
Modify binary dumping in h5dump to clean up files created [a band-aid
solution to not actually creating the files in the srcdir, but better than
just leaving the files around... :-/ ]
Tested:
FreeBSD 4.11 (sleipnir) (w/ configure flags above)
Too minor to require h5committest
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.
ttsafe test failed on the tts_error call. The error was due to the outdated
expected error stack; fixed.
Test was also moved to use new error APIs.
Platforms tested: Linux 2.4 (heping) and Solaris 2.9 (shanti)
"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.
Fix the last scattered bunch of problems with the object deletion code,
which appears to be completely working now (for objects that are stored
within heap blocks - standalone objects aren't implemented yet).
Also, re-work the regression test to speed up some of the existing tests
and add in 100-200 more combinations of tests - overall, its probably even
slower than it was... :-/
Tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4 (chicago)

Checkpoint further work on object deletion code for fractal heaps. I
believe everything is finally working for this sub-task. More regression tests

Refactored object deletion code for fractal heap to fix scaling problems.
Passing all previous tests again now.
Tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4 (chicago)
Mac OS X (amazon)
1) Added trace file support to the metadata cache. This allows capture
of all metadata cache calls in trace files for purposes of optimization
and debuging.
2) Added an expunge entry function. This allows an entry to be deleteded
from the cache without writing it to disk even if it is dirty.
3) Added a function call to resize pinned entries.
4) Added code to deal with entries that are dirty on load. This is
needed in support of a bug fix which can alter object headers on
load to repair files.
5) Added progress reporting code to the "MDC API smoke check" test in
cache_api.c. To enable the progress reporting, set report_progress
to TRUE in mdc_api_call_smoke_check().
Tested with h5committest, and a parallel test on phoenix (dual athelon
linux box).
adjustment
Description:
These tests (fheap, btree2) are under development and are not used by
the library yet. Move them to the end so that their failure do not block
other current library code tests.
Platforms tested:
heping.
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 checkpoint

the two random tests.)
fheap:
Changed the express mode messages to be more informative.
Un-excluded some tests from express mode.
Platforms tested:

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
New feature

Linux 2.4 (chicago) w/ & w/o group-revision enabled
h5committest
Description: Mac OS 10.4 on PowerPC chip has some errors to convert (unsigned)
long long to long double. When the bit sequences are 0x003ff..., 0x007fff...,
0x00ffff..., 0x01ffff..., 0x7fffff..., the converted values are twice as big
as they should be.
Solution: Detect the error in configure and disable the compiler conversion
and test case.
Platforms tested: h5committest, Mac OS 10.4, and fuss.
Bug fix
Description:
Since the new default Express level is 1, some fheap tests were being skipped.
Solution:
At least temporarily, fheap now skips these tests if it is run at express level 2
or greater.
Platforms tested:
mir
Configuration feature
Description:
'make install' now tests both static and shared libraries if both are installed.
Solution:
Previously, shared libraries were only tested when static libraries were not installed.
Also cleaned up line in commence.am that was including HL library in all Makefiles.
Platforms tested:
mir (Makefile change only)
testing feature
Description:
HDF5 Test Express change; now accepts values 0 to 3.
Solution:
As explained in the RFC and documented in the code, there are now four
levels of "express-ness", 0 (no limit) to 3 (1 min limit).
It is now up to test writers to take advantage of the various levels
to tune their tests' run times.
Platforms tested:
mir (minor change)
Description: Data conversion from long double to (unsigned) long long
returns some incorrect values on Mac OS 10.4 and SGI IRIX64 6.5. The
conversions start to go wrong when the long double is
20041683600089727.779961 (0x4351ccf385ebc8a0bfcc2a...). If adjusting
the values higher by assigning 0x...c8a0cf... or 0x...c8a0df..., the
converted values go wild.
Solution: Detect this error in configure.in and disable compiler
conversions from long double to (unsigned) long long for Mac OS 10.4
and IRIX64 6.5.
Platforms tested: h5committest, Mac OS 10.4, and IRIX64 6.5.
Code checkpoint
Description:
Add in more new features for the fractal heap code, mostly bringing in
more ability for deleting objects (which isn't completely working yet).
Also, checkpoint free space manager code, which is essentially complete
(although it needs some more work after the metadata cache has some additional
features)
Platforms tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4 (chicago)
h5committest
Bug fix
Description:
Fix bug which could lead to files with incorrect count of messages in the
header for an object. The exact sequence of operations is complicated and
is described in the release notes.
Solution:

Bug fix - bugzilla #552
Description:
On Cray X1, trying to use : as an argument confused the system.
Solution:
Added a test in configure to see if : as an argument is bad.
If so, skipped the test.
Platforms tested:
mir, Cray X1 (change to configure only)
Feature
Description:
Sometimes the parallel prefix is given in the form of nfs:/mnt/pfs which
if given to a non-MPIO VFD like the default H5Fcreate, it would fail.
Added a new routine h5_rmprefix which would return the non-prefix component
part of the file name which would be okay for the default H5Fcreate and
such.
Platforms tested:
Tested in heping parallel.
Added Exress Test mode.
Description:
The test takes a long time to run. It tempted developers to skip the
h5committest.
Solution:
Added Express Test mode to allow tester an option to run it in express
mode (shorter time.) There are already encoded QAK macro which skips
many tests. Follow that pattern to skip tests when HDF5TestExpress is
set.
Platforms tested:
Tested in heping, both serial and parallel.
1) Check in potential fix to unreproduceable bug in t_cache observed on
Cobalt
2) Check in code supporting added pinned entry features in the metadata
cache.
Description:
1) Elena encountered a bug in t_cache when running on Cobalt. On
investigation I found a potential race condition in t_cache that
could explain her observation.
2) Quincey requested additions to the metadata cache allowing renaming
of pinned entryies, and marking of pinned or protected entries as
dirty.
Solution:
1) Modified t_cache.c to prevent the potential race condition. Elena
was unable to reproduce the bug on Cobalt, so we don't know if my
fix actually addressed the problem.
2) Added code supporting the requested functions. The changes were
relatively trivial, but required substantial new test code.
Platforms tested:
h5committest, serial test on heping, parallel test on phoenix.
Misc. update:

Mac OS X.4/PPC (amazon)
Linux 2.4 (chicago & heping)
Solaris 2.9 (shanti)
AIX 5.? (copper) w/parallel
Bug fix.
Description:
The ${TR}, though avoid the error, is inconvenient. It is needed
because configure.in use the char range in the style of 'a-z'.
The other style of '[a-z]' is more commonly accepted by all tr
but autoconf tends to strip away [], making the syntax rather
clumsy.
Solution:
Learned from autoconf that it avoids the use of character range
by just spell all the letters out. Changed our tr commands to
use those variables defined by autoconf. Also removed the
definition of ${TR} since it will cause inconsistancy when
autoconf also use plain 'tr' in its generated code.
The Makefile.in are changed because the elimination of ${TR} from
configure triggered its removal from all Makefil.in. That is okay
because ${TR} is not used at all in Makefile.
Platforms tested:
h5committested. (sol failed to connected). also tested in shanti
using both /usr/ucb/tr and /bin/tr (the bad one before.)
Misc. update:
Updated both INSTALL and RELEASE files.

AIX 5.? (copper) w/FORTRAN & parallel
Description: Function prototype H5E_walk_t and structure H5E_error_t wasn't backward
compatible.
Solution: Make them compatible with v1.6 and provide new definitions of H5E_walk_stack_t
and H5E_error_stack_t.
Platforms tested: fuss and h5committest.
Purpose: Maintenance
Description: dtypes.c compilation failed with gcc 4.1 due to the
missing prototype of the opaque_funcs function.
Failure was reported by a user who tried to build
hdf5-1.8.0-alpha2.
I reproduced the failure on sleipnir with gcc41
compiler.
Solution: Added prototype definition.
Platforms tested: sleipnir with gcc41, heping and copper
Misc. update:

The datatype is now closed in the test.
Platforms tested:
windows, mir, copper
Bug fix
Description:
Fix two test bugs:
1) Unitialized variable bug in test of H5C_get_entry_status()
(in test/cache.c)
2) Incorrect initialization of constant in t_cache when running
with MPE. (in testpar/t_cache.c)
Solution:
1) Don't test uninitialize variable.
2) Correct initialzation of constant in MPE case.
Platforms tested:
Tested on Heping and Copper.
Misc. update:
Code checkpoint
Description:
More progress on fractal heap, can now re-open an existing heap, although
the free space algorithm still needs work.

This change propagated into a few of the tests, which also had some
compiler warnings cleaned up...
Platforms tested:
FreeBSD 4.11 (sleipnir) w/parallel
Linux 2.4/64 (mir) w/C++ & FORTRAN
Add pinned entry capability to cache.
Description:
For frequently accessed cache entries, the protect/unprotect overhead
is sometimes a bottleneck.
Solution:
Allow entries to be pinned in the cache. Pinned entries can't be
evicted, but can be flushed or modified.
Platforms tested:
h5committested -- minus one small typo in test/cache.c whose fix was
tested on copper and heping only.
Misc. update:
Several bug fixes
Description:
Added config file for Cray X1 (previous file was misnamed)
Simplified some code in hyperslab.c test that seemed to have been
confusing compiler on Cray X1.
Fixed typo in config/commence.am
Cleaned up hl/src/Makefile.am
Solution:
All four fixes should be straightforward. The failure on Cray was
very difficult to debug, but involved arithmetic errors.
This change seems to fix it.
Platforms tested:
heping, copper, sol, some Cray X1 (more testing when system comes back up)
Description:
The file size test in C++ library failed on Copper because the
value returned by h5_get_file_size was intepreted incorrectly
due to different interger sizes.
Solution:
H5private.h: Added check to use stat64 and off64_t where appropriate.
h5test.c and h5test.h: used h5_stat_size_t in place of off_t.
tattr.cpp: used h5_stat_size_t in place of off_t.

Bug fix.
Description:
getenv_all would fail if one calls it without calling MPI_initialized first.

Platforms tested:
FreeBSD 4.11 (sleipnir)
Too minor to require h5committest
Description: By default on VMS system file cannot be opened twice; also
VMS has file versioning. This brakes some of our tests.
Solution:
Tests are commented out with H5_CANNOT_OPEN_TWICE and H5_HAVE_FILE_VERSIONS
that are defined in the vms/h5pubconf.h file only. This change cannot affect
any other platform.
Platforms tested: heping, VMS server
Misc. update:
Bug fix/Feature
Description:
Modify the library to use rand_r, when available, instead of srand. If
rand_r is not available, it will try to use srandom/random, and then finally
fall back to srand/rand.
Solution:
A couple places in the library use the srand() function to seed the random
number generator. This can cause problems on certain platforms and could theoretically
cause problems for users who expect a certain sequence of random numbers following their
own call to srand().
Most platforms have an implementation of rand_r, which is identical to rand, except that
it allows for explicit storage of the seed value. The configure script will now check
for the existence of rand_r to facilitate its use in the library.
Two new functions are added, to replace the macros HDsrand/HDrand. These functions are HDrand and
HDsrand. HDrand will call rand_r, if available, or random(), if available, and fall back to rand() if neither
of those is available. HDsrand will store the seed value locally, if rand_r is available. Otherwise, it will call
srandom if available, and fall back to srand otherwise.
Platforms tested:
heping, mir. Really need to test on Red Storm, since that platform motivated this fix, but the machine
is currently not available.
Misc. update:
Bug fix (sorta)
Description:
Disable the fractal heap tests until I can look into them more thoroughly.
(they are failing on 64-bit machines currently)
Platforms tested:
None - trivial change.
