The static szip libraries are working as intended, but when shared szip
libraries are present and intended for use they cannot be opened. A check
has been implemented to test if shared szip libraries are functional on
current platform. If they are not, and the user is trying to use them,
szip is now disbaled and the user is informed.
This issue occurs on kagiso, and the resolution was tested on kagiso.
Tested platform:
Kagiso only since it is only a comment block change. If it works in one
machine, it should work in all, I hope. Still need to check the parallel
build on copper.
Move fill value messages into new shared message method calling scheme.
Only update an opened dataset's fill value property if it's different from
the default fill value settings.
Tested on:
Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago2)
Checkpoint work toward getting the fill value message into the shared
message interface regime.
Tested on:
Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago2)
Get rid of two different types of fill value struct (merge H5O_fill_t
and H5O_fill_new_t) and clean up & simplify dataset initialization code.
(In preparation for shared object header message method call
refactoring).
Tested on:
FreeBSD/32 6.2 (duty)
Mac OS X/32 10.4.8 (amazon)
would become shared NULL messages (oops!).
Added a test for this case.
Also fixed the #define that caused errors on Windows (and probably other
platforms). This may fix the Daily Test error.
Tested on Windows, smirom, kagiso, and juniper.
Migrate more object header routines to use the H5O_msg_ prefix and put
them into the src/H5Omessage.c code module.
Tested on:
Mac OS X/32 10.4.8 (amazon)
FreeBSD/32 4.11 (sleipnir)
Linux/32 2.4 (heping)
AIX/32 5.? (copper)
Clean up warnings assigned to me from today's meeting - still need
to tackle the datatype conversion ones...
Tested on:
FreeBSD/32 4.11 (sleipnir)
Linux/32 2.4 (heping)
Linux/64 2.4 (mir)
Refactor generic property list initialization code to put property list
specific routines in property list modules, instead of scattered to the four
winds. Also, introduce property list class initialization objects, to make
adding new property list classes in the library easier.
Fix daily test failure by using H5Pget_elink_prefix() API routine instead
of looking at the "raw" generic property list information.
Tested on:
Mac OS X/32 10.4.8 (amazon)
FreeBSD/32 4.11 (sleipnir) w/threadsafe
Linux/32 2.4 (heping) w/C++ & FORTRAN
Linux/64 2.4 (mir) w/build-all & 1.6 compat
Finish new version of the I/O pipeline message, which is much smaller than
the previous version. This version is used with the "use the latest version
of the format" flag.
Closed several memory leaks/overruns (found with valgrind).
Also, lots of compiler & formatting cleanups.
Tested on:
Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago2)
Configure feature
Description:
Added 'make trace' target.
Solution:
Added tracing to 1.7. This was done automatically in 1.6, but left out
of 1.7 until now (oops!).
Tracing in 1.7 only happens manually, when the user types 'make trace.'
Tracing automatically requires more framework than it's worth.
I also fixed a couple of tracing bugs and ran trace.
Platforms tested:
mir, sleipnir, modi4
Misc. update:
Description: H5T_register() replaces any existing data conversion path
with a new path.
Solution: Added a parameter to H5T_register() and H5T_path_find() to
signal the library whether the new conversion path is from API function
H5Tregister() or from private function like H5T_init_interface(). If it
is from H5Tregister(), replace existing path. If it's from H5T_init_interface()
and the library is trying to register default hard conversion functions,
don't replace existing path because the path is registered by the library.
For example, the library registered H5T_conv_int_float() and is trying to
register H5T_conv_long_float(). The size of long is equal to int. There's
no need to replace the path H5T_conv_int_float().
Platforms tested: h5committest and fuss.
Code cleanup
Description:
Changed some scale+offset filter symbols from H5_SO_... -> H5Z_SO_...
to indicate that they are in the H5Z package.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Too minor to require h5committest
Update scaleoffset filter.
Description:
1. Using enum type to describe scale offset type(int, Dscale or Escale)
2. Changing some macro names
3. Fixing some minor bugs
Solution:
Platforms tested:
sol 2.8, linux 2.4, aix 5.1(32-bit and 64-bit)
Misc. update:
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
New feature.
Description:
The H5Pset_scaleoffset is changed for the scaleoffset filter
to handle both integer and floating-point data. Currently,
the D-scaling method from GRIB has been implemented for
compressing floating-point data.
Solution:
One more parameter is added to the H5Pset_scaleoffset interface
to let user specify what type of data is used and what method
to use as well as corresponding parameters.

Description:
Add H5Zset_scaleoffset function for setting up the scaleoffset filter.
Solution:
Platforms tested:

Misc. update:
Description: Removed PABLO from the source
Solution:
Platforms tested: arabica with 64-bit, copper with parallel,
heping with GNU C and C++ and PGI fortran (but
I disabled hl, there is some weird problem only
on heping: F9XMODFLAG is not
propagated to the Makefile files
Misc. update:
Adding framework of N-bit filter
Description:
N-bit filter is required for NetCDF project.
To add N-bit filter, configure.in configure, Makefile.in under src and other
filter-related source code needs to be updated.
Currently, N-bit tests are turned off from the library. So the change will affect daily test.
Solution:
Platforms tested:
sol 2.7, linux 2.4, aix 5.1
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:
Change how default allocation time is handled internally to the library,
to avoid some performance issues with property lists.
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel
Solaris 2.7 (arabica)
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.

Code cleanup
Description:
Clean up almost all warnings from Windows builds.
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel
Too minor to require h5committest
Purpose:
HDF5 now supports SZIP with no encoder.
Description:
SZIP can be configured to have both encoder and decoder or just to have the decoder. HDF5 can now query the configuration of any filter, and will throw errors if users try to write using a filter with encoding disabled.
Solution:
Added H5Zget_filter_info function, changed API for H5Pget_filter and H5P_get_filter_by_id. See SZIP RFC.
Platforms tested:
Copper (fortran, C++, parallel), Sleipnir (C++), Arabica (fortran, C++), Verbena (fortran, C++)

Regenerate dependency files
Add htri_t as separate type from hbool_t for code tracing purposes.
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel
too minor to require h5committest
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,
reduces the library binary size a bit (about 2-3%) and should speedup the
library's execution slightly.
Platforms tested:
FreeBSD 4.10 (sleipnir) w/gcc34

Code optimization
Description:
Use 'size_t' instead of 'hsize_t' to track the number of elements in
memory buffers, especially for type conversion.
Platforms tested:

FreeBSD 4.10 (sleipnir) w/parallel
Too minor to require h5committest
Code optimization
Description:
Don't recompute the internal index value for looking up the chunk in the
hash table, just use the value already computed from iterating through the
chunks.
Platforms tested:
Solaris 2.7 (arabica)
FreeBSD 4.9 (sleipnir) w/parallel
Code optimization & bug fix
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.
Platforms tested:
FreeBSD 4.9 (sleipnir) w/parallel

Description:
Clean up lots of warnings based on those reported from the SGI compilers
as well as gcc.

FreeBSD 4.9 (sleipnir) w/ & w/o parallel
h5committest
Code cleanup/optimization
Description:
Query property list values once, at the beginning of the I/O routines,
instead of querying the property list values multiple (lots!) of times in
lower level routines.
Solution:
Create "property list caches" for internal library queries of the property
list values.

Misc. update:
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)
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)

Description:
Add in rest of szip "options mask" macros that were missing. Also made
"raw" options mask set by the library, instead of requiring users to always set
it.
