Refactor the file storage of "twig" nodes in the B-tree to allow them to
store more records, increasing the average density of the B-tree 30-40%.
Increase # of records in "insert lots" regression test to still create
B-tree of depth 4
Update h5debug to interpret difference of 'branch' and 'twig' internal
nodes in B-tree correctly.
Tested on:
FreeBSD/32 4.11 (sleipnir)
Linux/32 2.4 (heping)
Linux/64 2.4 (mir)
Solaris/64 2.9 (shanti)
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
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)
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.
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)
"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.
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
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)
Description: Added new tests for the h5stat tool; added --version flag
to display library version information and updated expected
output files.
Solution:
Platforms tested: heping, shanti
Misc. update:
Description: Added new tests for the h5stat tool; added --version flag
to the h5stat tool to display library version information
Solution:
Platforms tested: heping, shanti
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)
Description: I am checking in changes for the h5stat tool:
- updated Makefile.am to use tools library
- regenerated Makefile.in
- added command flags to display selected information
- added support for external files and filters
- small output formatting changes
For more information about current features and output see
updated h5stat RFC http://hdf.ncsa.uiuc.edu/RFC/h5stat/h5stat-spec.pdf
Solution:
Platforms tested: mir, heping, shanti, copper 64-bit, copper 32-bit parallel
using files from tools/testfiles directory and some NASA files
from our Web site.
Misc. update:
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.
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
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)
Anti-feature
Description:
Revert changes to H5G_stat_t struct, to make it compatible with the 1.6.x
branch again. The information that was added to the H5G_stat_t struct will
be reported through other API routines.
Platforms tested:
FreeBSD 4.11 (sleipnir) w/C++
Linux 2.4/64 (mir) w/C++ & Fortran
Solaris 2.9 (shanti)
new feature
Description:
1) separated the HL library into "public" and "private" header files, with the same caracteristics as the basic library
2) added the public headers to hdf5.h (with a conditional include macro, defined in configure.in)
3) added the path to HL in all Makefile.am 's , because of the inclusion in hdf5.h
Solution:
Platforms tested:
linux 32, 64
AIX
solaris
with fortran and c++
(one packet table example fails)
Misc. update:
Bug fix
Description:
Previous checkin did a bad thing; 'make clean' failed in example directories.
Solution:
Fixed commence.am so that examples no longer break, and fixed a mistake
in conclude.am.
Platforms tested:
heping (minor makefile change)
Misc. update:
Bug fix
Description:
make check-clean didn't clean results of example tests
Solution:
Fixed Makefiles so that check-clean recurses into example directories.
Also a little Makefile cleanup.
Platforms tested:
mir, modi4, heping, copper
Code checkpoint
Description:
The fractal heap code is reasonably stable and is passing all its
current tests, so checkpoint everything with CVS.
Also, add "statistics" module for v2 B-trees code, which is only a
stub right now.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Mac OSX (amazon)
Linux 2.4 (chicago)
Description: Return value from H5Pget_layout is 0 for the compact datasets;
It was assumed in the code that it was always greater than 0; therefore
assertion failed when h5stat walked a compact dataset.
Solution: Fixed assertion statement
Platforms tested: h5stat doesn't have testscript yet; tested manually
with tfilters.h5 file on heping.
Fix is too minor to test it on multiple platforms.
Misc. update:
New feature & code cleanup
Description:
Update fractal heap to be able to insert objects into a direct block
hanging off the header.
Extract "octal dump" code into separate routine so that both the local
heaps & fractal heaps can use it.
Other code cleanups & support to get this far.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4
New feature
Description:
Check in initial "fractal heap" code, for supporting the group redesign.
Also, remove some remnants of the segmented heap/block tracker/B+tree code
which I didn't find during the last pass.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Mac OSX (amazon)
Linux 2.4
Maintenance
Description:
Remove half-built (half-baked? :-) implementation of B+tree, block tracker
and segmented heaps. (In preparation for starting the new heap coding)
Platforms tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4 (heping)
Code cleanup
Description:
Check in some of the code cleanups from working on the external link
support. (This doesn't include any of the external link features)
Platforms tested:
FreeBSD 4.11 (sleipnir)
Mac OSX.4 (amazon)
Linux 2.4
Bug fix
Description:
Remove several macros that are already defined in H5private.h and are
causing failures on copper.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Too minor to require h5committest
Bug fix
Description:
Include more header files with prototypes to make CC=g++ builds work.
Platforms tested:
FreeBSD 4.11 (sleipnir) w/CC=g++
Too minor to require h5committest
Code cleanup
Description:
Fix a bunch of warnings flagged by Windows compilers.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Too minor to require h5committest
Bug fix
Description:
Fortran type generation was broken in two ways. Fixed both.
Solution:
Firstly, there were a couple of path problems. Fixed a typo and
specified the full path of a file.
Secondly, the dependencies weren't right when building with HDF5-specific
commands (make lib, make check-s, etc.). Tweaked dependencies
to fix the problem.
Platforms tested:
mir, modi4, sleipnir
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:
Bug fix
Description:
Before this checkin, 'gmake check-s' would fail if there was a file in
the current directory named 'check-s'.
This is fixed under gmake (not sure how to fix for other makes).
Solution:
check, progs, install, etc. are what gmake calls "phony" targets,
which means that no file should be created. These targets can be
specified by a line of the form
.PHONY: check progs install ...
Automake adds this line for targets it knows about, but HDF5 has a
lot of custom rules. This checkin adds a .PHONY line for those rules.
I believe that only gmake recognizes the .PHONY line (at least, pmake
doesn't seem to), but a partial solution is better than none.
This error should occur very rarely anyway (the user has to manually
create files with names like 'build-check-s' or '_test').
Platforms tested:
mir, sleipnir, modi4
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.... :-)
Bug fix/feature
Description:
Added support for -shlib in h5fc and h5c++.
Made check-install use -shlib when only shared libraries have been installed.
Solution:
h5fc and h5c++ didn't recognize -shlib. Stole code from h5cc to link against
shared libraries.
When static libraries are disabled, the examples Makefiles will automatically
use the -shlib option to link against shared libraries. Thus,
--disable-static and make check-install should work together.
Platforms tested:
heping(disable-static, enable-static, fortran, c++), modi4 (disable-static, fortran, c++, parallel, enable-static)
Update copyrights.
Description:
Solution:
This should address almost all of the "simple" cases in the repository.
There's still work to do, but it's going to require actually thinking about
the files in question instead of just copying & pasting.
Bug fix
Description:
Failed parallel tests now cause make to exit with an error.
Solution:
Edited config/conclude.am to throw an error if parallel test programs fail.
Platforms tested:
heping, modi4
Added additional targets to build-all
Description:
Surveyed files to find out which ones are not built.
Added test/space_overflow and perform/benchpar to programs built with
--enable-build-all.
Discovered that tools/misc/pdb2hdf5 and tools/misc/h5import were
obsolete and deleted them.
Platforms tested:
mir, modi4, sol
Misc. update:
Update of release file and removal of --enable-pdb2hdf5 to follow.
Bug fix
Description:
Changed configure.in to use an environment variable TR to set the path
to the tr utility.
Solution:
There are two kind of tr on Solaris with slightly different syntax.
HDF5's configure relies on the "standard" tr. Traditionally, HDF5ers
have needed to make sure that the "right" tr was found before the
wrong one in their path; now they can use an environment variable.
Platforms tested:
mir, shanti, sol
Misc. update:
Forgot to update release notes. Off to do that now.
Makefile bug fix
Description:
Previously, automake didn't output rules to build perform/mpi-perf or
the test/gen_* programs.
Now these can be built by typing 'make mpi-perf' (or 'make foo') or by
configuring with --enable-build-all.
Solution:
Automake doesn't like having rules for programs it doesn't build. Tricked
it by having these programs built "sometimes"--whenever the user enables
--build-all. This should be used mostly for testing and to ensure that
these helper programs compile.
***IMPORTANT***
These programs do *not* currently compile. When --enable-build-all is used
(not the default), gen_new_fill fails because it uses an old API. This is
an existing "bug" that has simply been exposed by this checkin.
Platforms tested:
sleipnir, modi4, sol
Misc. update:
bug fix.
Description:
When a parallel test script test fails, make would continue because the
way it was setup inside a for loop. Fixed it by issuing an exit 1 inside
the loop.
There was also a typo error in the newer command comparision that it
must be $${chkname} in order to be valid. Also, the test script itself
was not checked in the newer lists. All fixed.
Platforms tested:
h5committested and also hand tested in heping pp mode.
New feature.
Description:
Added the time command to the make check target to report time usage
of the execute of each test and test scripts. This gives us some idea
how long each test takes and some vague idea it is compute bound or
not.
powerpc-ibm-aix5.x:
Change $RUNPARALLEL default setting to allow it being invoked by the
time command.
Platforms tested:
h5committested.
Feature
Description:
Added H5_CFLAGS, etc. to 1.7 branch.
Now compilation flags can be put in H5_*FLAGS and they'll be used when
building hdf5 but not in h5cc.
Platforms tested:
mir, sleipnir, modi4
Misc. update:
Bug fix
Description:
Disabled C++ shared libraries for Sun Workshop compiler.
Solution:
This bug only seems to happen when using the -xarch=v9 flag to compile in
64-bit mode, but disabling shared libraries entirely for this compiler is
an easier fix (I don't know how to detect 64 bit mode from the command line).
The framework for disabling shared libraries for other C++ compilers is
in place.
Platforms tested:
sol, mir, sleipnir, modi4
