Add support for checksumming fractal heaps. This is always enabled for
the heap header and indirect blocks (as they are "pure" metadata) and is
optional for direct blocks, since they may be used for "raw" data.
Also, rearrange direct block routines in H5HFcache.c to be in a more
sensible location in the file. (probably should have been a separate checkin,
since the diffs are mostly useless for this checkin... *sigh*)
Tested on:
Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago2)
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
Tweak the library's new faster fletcher32 algorithm to always produce the
same checksum as the previous fletcher32 code in the fletcher32 I/O pipeline
filter and switch the filter to use the library's version of the algorithm.
Tested on:
Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago2)
Too minor to require h5committest
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...
Add a bunch more regression tests:
- Verify opening a fractal heap more than once works correctly
- Check that 0 & 1-sized object insertions are handled correctly
- Check that bad heap IDs are detected when attempting to read an
object
- Check that doubling tables with different parameter values are
working correctly
Add some more checks to the code to detect 0-sized object insertions and
bad heap IDs for reading.
Tested On:
FreeBSD/32 4.11 (sleipnir)
Linux/32 2.4 (heping)
Linux/64 2.4 (mir)
Solaris/64 2.9 (shanti)
- Migrate "direct block location" routine from H5HFman.c to H5HFdblock.c,
which is a more appropriate location
- Optimize performance of heap code by taking advantage of pinned
indirect blocks and use them without putting a metadata cache
protect/unprotect pair around them.
- Other minor compiler warning cleanups and optimizations...
Tested On:
FreeBSD/32 4.11 (sleipnir)
Linux/64 2.4 (mir)
Solaris/64 2.9 (shanti)
Object header locations (H5O_loc_t's) can now "hold open" a file and
decrement its open object count when they close. This means that
locations (H5O_loc_t's and H5G_loc_t's) should always be freed.
Added more thorough tests to ensure that external files are closed.
flag, and pin an entry as it is inserted.
The objective is to avoid some function call overhead in fheap.
Also added matching test code in test/cache.c & test/cache_common.c
(also testpar/t_cache.c checked in separately by accident)
h5commit tested
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)
Allow the heap ID length to be chosen at heap creation time, to allow
for making heap IDs long enough to directly embed the file offset & length
of 'huge' objects in the heap ID (which allows them to be retrieved directly
from disk, instead of requiring them to be looked up in the B-tree that tracks
'huge' objects)
Tested on:
FreeBSD/32 4.11 (sleipnir)
Linux/64 2.4 (mir)
Solaris/64 9 (shanti)
Clean up a couple of compiler warnings in the 'huge' object code in the
library.
Add a bunch of 'huge' object regression tests
Tested on:
FreeBSD 4.11 (sleipnir)
Linux/64 2.4 (mir)
Solaris/64 2.9 (shanti)
Move metadata cache address rename for fractal heap indirect block
immediately after reallocing the storage on disk - to prevent another
routine in the library from confusing the cache by allocating more storage
and attempting to insert it in metadata cache at the old block's location.
Gotta like those monte carlo/random insert & delete tests, which exposed
this... :-)
Tested:
Solaris 2.9 (shanti)
Not failing on other machines
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)
Update code formatting a little and refactor to add a better mechanism
for performing callbacks when removing records from the B-tree or deleting
entire B-tree.
Testing:
FreeBSD 4.11 (sleipnir)
Linux/64 2.4 (mir)
Linux/32 2.4 (heping)
Mac OS 10.4 (amazon)
Daily test for ttsafe failed on several machines due to the changed error stack.
Solution:
Updated the source code to use new error stack.
Platforms tested:
shanti
More tweaks on fractal heap statistics, to better separate information
about managed objects from information about "huge" objects.
Also, clean up some compiler warnings, etc. on 64-bit platforms & Windows.
Platforms tested:
Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago)
Refactor fields in heap header to clean out information from dropped
features and also group related fields together more nicely.
Add fields to heap header for storing information about "huge" objects.
Platforms tested:
Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago)
Refactor fractal heap IDs to include "flag byte" as part of the ID. This
byte will be used for the heap ID format version as well as flags to indicate
whether the heap object is a "tiny"/normal/"huge" object (with storage
mechanisms optimized for each type of object).
Platforms tested:
Linux/32 2.4 (chicago)
Too minor to require h5committest
Clean up compiler warnings/failures in test/links.c, especially when
--disable-production flag used with --enable-group-revision
Modify binary dumping in h5dump to clean up files created [a band-aid
solution to not actually creating the files in the srcdir, but better than
just leaving the files around... :-/ ]
Tested:
FreeBSD 4.11 (sleipnir) (w/ configure flags above)
Too minor to require h5committest
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)
