Break out a bunch of the misc. routines that were in src/H5.c into more
specific modules.
Add optimized fletcher32 checksum routine, for checksumming metadata as
well as raw data.
Tested On:
Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago2)
Will test further after checkin...
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)
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)
Mac OS X.4 (amazon)
Added files created by James for user-define links to the command files
Added new script check_h5jam.com to test h5jam/h5unjam; test script
needs more work.
Platforms tested:
VMS server and test script only.
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.
Added test script to test h5import tool; added new source file
to the make.com file in the src directory.
Platforms tested:
Only h5import was tested on the VMS server
Refactored free space manager to use metadata cache for serialized free
space sections. This speeds up the fractal heap test considerably...
Tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4/32 (chicago)
Linux 2.4/64 (mir)
Mac OS X (amazon)
1. changed the -F flag option names to "BE and "LE" for big and little endian
2. added a more verbose usage message for these options
3. add a new test
4. add a make clean instruction to *.bin
the last one
h5ls -w80 -v -S tattr2.h5
h5ls prints "native" for all types instead of the complete datatype definition.
I will look into the problem next.
it uses the API function H5Gcopy to copy groups and datasets from file
to file, read from a command line
note: the test script is not finished yet
tested on heping, copper, shanti
new feature
Description:
added support for h5dump to dump binary data using the file type format
added one test to the test script that tests this
Solution:
Platforms tested:
mir
shanti
copper
Misc. update:
new feature. h5dump output of binary data
Description:
a new switch -b FILE_NAME that dumps the contents of memory data to file FILE_NAME in binary form
new program binread.c that reads the contents of this file and outputs it to stdout
added a test for the h5dump shell script that does a run of -b
the binread.c program reads the data used in this run, usage is ./binread FILE_NAME
Solution:
Platforms tested:
linux
solaris
AIX
Misc. update:
Description: Added support for HPUX11.23
Solution: Added configuration file for the system.
Both C, C++, F90, HL 32-bit and 64-bit are supported. Known problems:
C++ library will not build in 64-bit mode if shared is enabled.
Platforms tested: HPUX 11.23 at UMKC
Misc. update:
Description: Added a command file for testing tools; it has a framework
to do exactly (almost) what UNIX tools test scripts do:
- run test tool and save output
- compare output with expected result
- figure out the difference and
- print PASSED /*FAILED* in a manner similar to the UNIX output
It needs to be populated with more tests and reused for other tools.
Solution:
Platforms tested: VMS server
Misc. update:
Description: Added test script and two test files in the tools/misc/testfiles
directory for testing h5stat tool; modified Makefile.am in tools/misc
and configure.in files to run the new test script; reran bin/recofigure
to update relevant configuration files; updated MANIFEST
Solution:
Platforms tested: heping with in place and srcdir builds; will do more testing
after the checkin.
Misc. update:
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)
Code checkpoint
Description:
Checkpoint fractal heap improvements, as well as move the free space
manager code that it's using into a separate package.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4/64 (mir) w/C++ & FORTRAN
Linux 2.4/32 (heping)
Solaris 2.9 (shanti)
AIX 5.? (copper) w/FORTRAN & parallel
Code checkpoint
Description:
More progress on fractal heap, can now re-open an existing heap, although
the free space algorithm still needs work.
Also, use the new "pinned entry" metadata cache code.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4 (heping)
Solaris 9 (shanti)
Linux 2.4/64 (mir)
Code cleanup
Description:
Big clean up on high-level library code, including:
- Removing include of HDF5 private header file(!)
- Reduce number of compiler warnings
- Untangle header files, etc.
Platforms tested:
FreeBSD 4.11 (sleipnir) w/C++
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:
new feature
Description:
added support for the printout of dataset region references differences
added a new test for this
merged the h5diff generator of test files into a single file
Solution:
Platforms tested:
linux 32, 64
solaris
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)
Bug fix.
Description:
./hl/src/H5LTparse.h was marked as DO_NOT_DISTRIBUTE by mistake.
It should not be installed but must be present for building.
Solution:
Fixed.
Platforms tested:
Should work.
