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 The error was due to the outdated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)
Mac OS X (amazon)
Checkpoint further work on object deletion code for fractal heaps. I
believe everything is finally working for this sub-task. More regression tests
soon, but I don't foresee any problems.
Machines:
FreeBSD 4.11 (sleipnir)
Linux 2.4 (chicago)
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
Description:
Revise fractal heap code to support deletions in up to 2nd level deep
indirect blocks. Needs some revisions to support deeper indirect blocks...
Platforms tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4 (chicago)
h5committest
Added/adjusted Test Express mode.
Description:
btree2:
Added TestExpress mode to skip some long tests (the 5th recursive and
the two random tests.)
fheap:
Changed the express mode messages to be more informative.
Un-excluded some tests from express mode.
Platforms tested:
Red Storm.
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
Description:
Check in Peter's code to add support for "shallow copy", "create
intermediate groups", "no attributes" and "expand soft links" support.
Platforms tested:
FreeBSD 4.11 (sleipnir)
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:
Mark merged null header messages as dirty.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4 (chicago)
Mac OS/X (amazon)
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:
Code checkpoint
Description:
Update fractal heap code to allow objects to be deleted
Fix bugs in fractal heap object insertion
Improve free space manager code to allow sections to be merged and
shrink the container
Another try at making the Windows compilers happy...
Platforms tested:
FreeBSD 4.11 (sleipnir)
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.
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
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:
Bug fix
Description:
A datatype wasn't being closed in th5s.c
Solution:
This minor oversight caused an error with my Object Header code.
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.
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/feature twist
Description:
Adjust recent H5AC routines to take H5F_t pointers instead of H5C_t
pointers, to match the rest of the H5AC routines.
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.
Platforms tested:
Linux 2.4 (heping)
AIX 5.1 (copper)
SunOS 5.8 64-bit (sol) - still on going
Bug fix.
Description:
It did not handle the case when version sub-release string is not
empty.
Solution:
Fixed the sed substitution to remove the sub-release string too.
Platforms tested:
Heping.
