Description:
the Data transformation code that failed when a data transform property
for simple expression is fixed. Turned the tests back on.
Platforms tested:
Tested in copper (pp) where the failure appeared. Also in eirene
as double check. No h5committest as the change is trivial.

Misc. update:
Code cleanup
Description:
Tweak recent "forward compatibility" changes to the H5E* API (which allowed
for the old H5E API functions to remain unchanged) by allowing for the error
stack callback function (H5E_auto_t) to also remain unchanged from the 1.6
branch. This required changing the H5E{get|set}_auto routines to have the
old style H5E_auto_t type (which didn't have a stack ID parameter) and the new
H5E{get|set}_auto_stack routines to have a newer "H5E_auto_stack_t" type (which
has a stack ID parameter). This should make the H5E API changes as forwardly
compatible as possible.
One side-affect of this change was that it was impossible to determine if
the current auto error callback was the old style (H5E_auto_t) or the new style
(H5E_auto_stack_t) of callback, so a new API function (H5Eauto_is_stack) was
adde to query this.

FreeBSD 4.10 (sleipnir)

Description: One place was left out for update after the Error API was modified.
Changed it from H5Eset_auto to H5Eset_auto_stack.
Platforms tested: sleipnir(with threadsafe) - simple change.
new test for the native types test
Description:
on the Cray SV1 an INT type was wrongly converted to a SHORT type
by the get_native_integer function
Choose the type based on the precision; this is to support cases
like the Cray SV1, where the size of short is 8 but precision is 32
(e.g an INT (size 8, prec 64) would be converted to a SHORT
(size 8, prec 32) if the size was the deciding factor)

Misc. update:
Description: A few items were left out when tried to restore the old Error API.
There are also a few minor bug fixes.
Platforms tested: arabica fuss h5committest.
Description: Restore 6 old error API functions back to the library to be backward
compatible with v1.6. They are H5Epush, H5Eprint, H5Ewalk, H5Eclear, H5Eset_auto,
H5Eget_auto. These functions do not have error stack as parameter.
Solution: Internally, these functions use default error stack.
Platforms tested: h5committest and fuss.

Also tested thread-safe option in eirene.
Feature
Description:
Changed TestParseCmdLine to accept an optional extra_parse()
function provided by indidivual test application. Extra_parse()
can handle extra options special to that test application.
Updated testhdf5.c to use the new syntax of TestParseCmdLine().
Platforms tested:
On eirene both serial and parallel.
Description: The test tried to read a dataset of H5T_STD_I32LE type and verify with the size
of H5T_NATIVE_INT in function test_misc20(). This will fail on some machines like Crays where the
size of H5T_NATIVE_INT is 8 bytes.
Solution: Changed from H5T_NATIVE_INT to H5T_STD_I32LE.
Platforms tested: Crays - very simple change.
Bug fix
Description:
Correct possible core dump when a datatype conversion function is
registered with the library after a compound datatype has been converted
(having it's type conversion information cached by the library). The compound
datatype must have been created by inserting the fields in non-increasing

Re-sort the fields in the compound datatypes before recalculating the
cached information when performing the conversion on them.

Bug fix.
Description:
Address two problems:
- The computation of the scanline in the szip filter was being
performed in the "can apply" callback routine instead of the
"set local" routine.
- The routine which allocated all the chunks for an entire dataset
(which is invoked when the allocation time is early or late,
rather than incremental) wasn't recording a failed filter in
the information for the chunk, causing the library to believe
that the chunk had the filter applied when it really hadn't.
Solution:
- Move the scanline computation to the "set local" callback.
- Record the filter mask with each chunk created when allocating them.
Platforms tested:

Description:
When a simple dataspace is created, its extent should be set before using it,
or it will silently function as a NULL dataspace.
Solution:
Added checks on user-supplied dataspaces. Now dataspaces without extents set
will throw errors; users must explicitly set a dataspace to be NULL.
Platforms tested:
sleipnir, windows
Purpose:
Bug fix
Description:
Modification time test (mtime) would die silently on some systems. This is
because the code is very system-dependant (it relies on getting the current
time and the timezone from the OS).
Solution:
mtime test now uses TEST_ERROR macro to print "FAILED" and to output where the
failure occurred. Configure script is a little smarter about whether
gettimeofday() function returns the timezone correctly.
Further bugs will need to be addressed on a system-by-system basis.

Description: This is the second step of checkin for encoding and decoding objects.
H5Tencode and H5Tdecode have been committed in the previous step. H5Sencode
and H5Sdecode are checked in this time.
Solution: Given object ID, these functions encode and decode object information
into and from binary buffer and return new object ID. They take advantage of the
existing codes of object header message and encode in the same format.
Platforms tested: fuss and h5committest.
Misc. update: RELEASE.txt
Purpose: Improvement
Description: HDF5 Library set pixels_per_scanline parameter to the size of the chunk's
fastest changing dimension. As a result, fastest changing dimension
of the chunk could not be bigger than 4K and smaller than pixels_per_block
value and szip compression couldn't be used for many real datasets.
Solution: Reworked algorithm how HDF5 sets pixels_per_scanline value; only chunks
with the total number of elements less than pixels_per_block value are rejected.
There is no restriction on the size of the chunk's fastest changing
dimension anymore.
Modified the test according to the new algorithm.

Platforms tested:
arabica, sleipnir
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.
Purpose:
Bug Fix
Description:
If an HDF5 file grows larger than its address space, it dies and is unable to
write any data. This is more likely to happen since users are able to change
the number of bytes used to store addresses in the file.
Solution:
HDF5 now throws an error instead of dying. In addition, it "reserves" address
space for the local heap and for object headers (which do not allocate space
immediately). This ensures that after the error occurs, there is enough address
space left to flush the entire file to disk, so no data is lost.

Description:
Correct problems with "resurrecting" a dataset in a file. (This occurs
when a dataset which is open gets unlinked from the group hierarchy (making it
"dead" and marked for deletion in the file) and then is re-linked to the group
hierarchy). Note that the current solution applies only to datasets, further
work will fix this for groups and named datatypes also.
Also, fix the "debug" routines to be a little more helpful in certain
situations.
Additionally, fix a locking bug in the symbol table node splitting routine
which could be [one of] the cause[s] of the file corruption in flexible
parallel operation.

Description:
The "shared" raw B-tree node can get freed before all the B-tree nodes

Too minor to require h5committest
Description:
Replaced the old metadata cache with a cache with a modified LRU
replacement policy. This should improve the hit rate.
Solution:
Since we want to flush cache entries in increasing address order, I
used the threaded binary B-tree code to store the cache entries.
There is a fair bit of overhead here, so we may want to consider
other options.
While the code is designed to allow the support of other replacement
algorithms, at present, only a modified version of LRU is supported.
The modified LRU algorithm requires that a user selectable portion
of the cache entries be clean. The clean entries are evicted first
when writes are not permitted. If the pool of clean entries is used
up, the cache grows beyond its user specified maximum size. The
cache can also exceed its maximum size if the combined size of the
protected (or locked) entries exceeds the maximum size of the cache.

Description:
When dimension information is being stored in the storage layout message
on disk, it is stored as 32-bit quantities, possibly truncating the dimension
information, if a dimension is greater than 32-bits in size.
Solution:
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 fix.
Description:
On LANL QSC, test/dtypes "sw long double -> double" had failed when the
long double values were too small, smaller than the minimum double normalized
floating number. The hw in QSC converts them mostly to 0 but occasionally,
it converts to the some non-zero values which are still <= the minimum
double normalized number. But the conversion verification did not like
them and flagged them as errors.
Solution:
Added code to check if the src value is already smaller than the minimum
number the float class can hold. When that happens and if both hw and sw
conversion results are <= the minimum number, then accepts them as okay
because if the src is smaller than the dst minimum number, an underflow
has occured.

Platforms tested:
Eirene (both serial and parallel).
Misc. update:
Improvement.
Description:
Verbosity level were specified by numbers which are not meaningful
and prone to typos.
Solution:
Adapted the Verbosity predefined level symbols from HDF4
and changed all numberic verbosity to symbolic values.
(Still need to convert some left over macros like MESSAGE.)
Platforms tested:
Eirene.
No h5committest since this is trivial.
Misc. update:
Add tests & docs
Description:
Added tests for the recent B-tree bug fixes & document their fix in the
release notes.
Platforms tested:
FreeBSD 4.9 (sleipnir)
Too minor to require h5committest
Bug fix
Description:
Correct two problems with variable-length datatypes in datasets:
- When overwriting an entire dataset, writing the fill value to the
file would be skipped, causing problems for VL datatypes when
objects in the file had been unlinked (and thus the space in the
file was not all zeros)
- When an application has set a fill-value for a dataset and the
dataset's datatype contained a VL datatype, the library was filling
space on disk with the memory form of the VL information, instead
of the disk form.
Platforms tested:
FreeBSD 4.9 (sleipnir)

Code cleanup & reorganization
Description:
Move further in the testing framework cleanup, eliminating all the
global variables (moving them into testframe.c as static variables) from the
testing framework code and moving it into the libh5test.a.
Platforms tested:
FreeBSD 4.9 (sleipnir) w & w/o thread-safety, c++ & parallel

Bug fix
Description:
Add some more #ifdefs to fix 1.6 compatibility failures
Platforms tested:
FreeBSD 4.9 (sleipnir) w/1.6 compatibility
Too minor to require h5committest
Bug fix
Description:
When two property lists are compared, the H5Pequal routine was just
comparing the raw information for the property values. This causes problems
when the raw information contains pointers to other information.
Solution:
Allow a 'compare' callback to be registered for properties, so that a user
application get perform the comparison itself, allowing for "deep" compares of
the property value.
This was exported to the H5Pregister & H5Pinsert routines in the development
branch, but not the release branch.
Platforms tested:
FreeBSD 4.9 (sleipnir)
h5committest
Code cleanup
Description:
Refactor library testing framework (used for the testhdf5 & ttsafe tests)
to remove almost all of the duplicated code, moving the common code into a
new 'testframe.c' source file.
Platforms tested:
FreeBSD 4.9 (sleipnir) w & w/o thread-safety
h5committest
Fixed a dumb mistake.
Description:
Other tests barked at the changes.
Solution:
Move the declaration of Index and Test[] into h5test.c.
Platforms tested:
Tested in eirene.
Misc. update:
Code reorg.
Description:
Move the InitTest() from individual tests (testhdf5 and ttsafe) to
libh5test (h5test.c) so that it can be shared among all tests.
Platforms tested:
Only tested in Eirene via serial with thread-safe enabled.
No other platforms test since this is pretty trivial.
Bug fix
Description:
Add special-case handling to floating-point conversion tests to avoid
problems with denormalized values on Cray T3E & T90 platforms. (Still not
working on Cray SV1, but at least it's closer).
Solution:
Detect denormalized values and don't try to operate on them on the Crays.
Platforms tested:
FreeBSD 4.9 (sleipnir)
Cray T3E (hubble.cray.com)
Cray T90 (gypsy.cray.com)
Bug fix
Description:
Range check the szip 'pixels per block' against the chunk size of the
dataset when attempting to create a new dataset, since the szip library
requires the PPB to be at least the size of the fastest changing dimension
in the chunk.
Platforms tested:
FreeBSD 4.9 (sleipnir)
too minor for h5committest
Code cleanup
Description:
Switch 'malloc()' to 'HDmalloc()' in a bunch of places.

Code cleanup for VS.NET
Description:
Clean up several issues that VS.NET was having problems with.
Platforms tested:
Eyeballed against Kent's bug reports.
Bug fix
Description:
Attributes which were created with scalar dataspaces were reporting their
dataspace as a simple dataspace when queried later.
Solution:
Fix the dataspace handling code when reading in the attribute message from
the file to set the extent type correctly.

Bug fix.
Description:
Using a selection offset with hyperslab selections in chunked datasets
was getting into an infinite loop and hanging the application.
Solution:
Apply the selection offset to the hyperslab selection properly.

Bug fix/code cleanup
Description:
When an error occurs, assume that it will be in the "real" output file and
use that to display the diff against.

Misc. update:
Bug fix
Description:
Handle denormalized floating-point values in a more general way that
uses a different 'epsilon' for determining if two values are "close enough"

Bug fix
Description:
C++ compiler was choking on passing a (hsize_t *) to a function which wants
a (uint8_t *).
Solution:
Cast the (hsize_t *) to a (uint8_t *)... :-)
