Bring revisions from Coverity session from hdf5_1_8_coverity branch to
trunk:
r18214:
Issue 423: cache_ptr was not initialized. if global 'pass' was false,
cache_ptr could be used. Extended scope of if(pass) block to include whole
function-flush_cache().
r18215:
Fix coverity item 317. Removed unreachable code in H5B2_hdr_alloc.
r18216:
Fixed Coverity issues 57 & 67. Checked oid_count > 0 before memory allocation
and oid_list != NULL before dereferencing.
Tested on:
Mac OS X/32 10.6.2 (amazon) w/debug & production
(daily tested on Coverity branch already)
The previous implementation did not work for WIndows.
Moved the macro definition of HDGetTestVerbosity from testhdf5.h
to h5test.h.
Removed as much as possible macro definitions that use HDGetTestVerbosity
directly.
Tested: Jam (serial and parallel). Did not run h5committest since this
is a trival change that is portable.
GetTestVerbosity() is called many times during tests. Implemented a more
efficient macro version HDGetTestVerbosity.
Tested: Jam (serial and parallel). Did not run h5committest since this
is a trival change that is portable, I am 99% sure.
Fix a few more problems when the user block is not aligned properly.
Tested on:
FreeBSD/32 6.3 (duty) in debug mode
FreeBSD/64 6.3 (liberty) w/C++ & FORTRAN, in debug mode

for it, too. This round of checkin isn't well tarnished yet. I'll come back to work on Jan. 8. I'll revise it then.
Tested it on kagiso, smirom, linew.
Rename new error handling API routines from H5E<foo>_stack() to
H5E<foo>2().
Tested on:
Mac OS X/32 10.4.9 (amazon)
FreeBSD/32 6.2 (duty)
FreeBSD/64 6.2 (liberty)
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.
This feature is still in progress; Shared Object Header Messages are not
complete as a feature and are not thoroughly tested. There are still
"TODO" comments in the code (comments with the word "JAMES" in them,
so as not to be confused with other TODO comments).
Hopefully this checkin will reduce the liklihood of conflicts as I finish
implementing this feature.
All current tests pass on juniper, copper (parallel), heping, kagiso, and mir.
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...
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.
Bug fix
Description:
Rewrite code for mounting files to clean up layers of kludges and implement
a much cleaner and more maintainable design.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4
Feature
Description:
Added "support" for UTF-8 character encoding.
Solution:
Wrote tests to check that UTF-8 can be used in a number of places in
HDF5 (object names, data, etc.). These tests live in test/tunicode.c.
Added a new UTF-8 character encoding for datatypes.
Platforms tested:
mir, modi4, heping
Misc. update:
Remove feature
Description:
Retire threaded, balanced binary tree code from HDF5 use. Requiescat in
pace...
Also, regenerate dependencies files.
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel
Too minor to require full h5committesting (the code is already
disconnected from everything except its tests)
Add new internal data structure
Description:
Add an implementation of skip lists to the library (see comment in
src/H5SL.c for references to the papers describing them) as a potential
replacement for our current threaded, balanced binary tree container.
Skip lists are much simpler to implement and should be faster to use.
Also, added new error codes to release branch, so bump the minor version
number to indicate that the library is no longer perfectly compatible with
the 1.6.3 release.
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel
Solaris 2.7 (arabica)
Too minor to require further testing (the skip lists aren't actually
used by any library code yet)
Description: Restore 6 old error API functions back to the library to be backward
compatible with v1.6. They are H5Epush, H5Eprint, H5Ewalk, H5Eclear, H5Eset_auto,
H5Eget_auto. These functions do not have error stack as parameter.
Solution: Internally, these functions use default error stack.
Platforms tested: h5committest and fuss.
Misc. update: RELEASE.txt
Code cleanup.
Description:
The routines residing in testframe.c was defined in testhdf5.h due to
historical reason. It really belongs to h5test.h because those routines
reside in libh55test.a.
Solution:
Moved them to the right place. Also removed the duplicated occurance
of testframe.c in the TEST_SRC.
Platforms tested:
Tested in o2 (SGI) parallel.
Bug fix
Description:
C++ compilers do not like the variable name new which is a kind word
for C++. Changed it to newval instead.
Platforms tested:
Tested in Copper which is the one complained about the name.
New feature.
Description:
Added function SetTestVerbosity() so that other applications can
set the verbosity explicitedly without the whole testframe taking
over.
Added Verbose queries shorthands to make code more readable and
easier to change the levels of low, medium and high.
Platforms tested:
Eirene (both serial and parallel).
Misc. update:
Improvement.
Description:
Verbosity level were specified by numbers which are not meaningful
and prone to typos.
Solution:
Adapted the Verbosity predefined level symbols from HDF4
and changed all numberic verbosity to symbolic values.
(Still need to convert some left over macros like MESSAGE.)
Platforms tested:
Eirene.
No h5committest since this is trivial.
Misc. update:
Code cleanup & reorganization
Description:
Move further in the testing framework cleanup, eliminating all the
global variables (moving them into testframe.c as static variables) from the
testing framework code and moving it into the libh5test.a.
Platforms tested:
FreeBSD 4.9 (sleipnir) w & w/o thread-safety, c++ & parallel
h5committested
Code cleanup
Description:
Refactor library testing framework (used for the testhdf5 & ttsafe tests)
to remove almost all of the duplicated code, moving the common code into a
new 'testframe.c' source file.
Platforms tested:
FreeBSD 4.9 (sleipnir) w & w/o thread-safety
h5committest
Code cleanup
Description:
Clean up comments, etc.
Platforms tested:
FreeBSD 4.8 (sleipnir) w/C++
Linux 2.4 (burrwhite) w/FORTRAN
Solaris 2.7 (arabica) w/FORTRAN
IRIX64 6.5 (modi4) w/parallel & FORTRAN
(h5committest not run due to my ongoing difficulties with C++ on burrwhite).
Update
Description:
Updated the Copyright statement
Platforms tested:
Linux (This change is only in the comments, so I just check that the
modules still compile)
Misc. update:
Code cleanup
Description:
Added more information to information printed for test failure.
Platforms tested:
Tested h5committest {arabica (fortran), eirene (fortran, C++)
modi4 (parallel, fortran)}
Lots of performance improvements & a couple new internal API interfaces.
Description:
Performance Improvements:
- Cached file offset & length sizes in shared file struct, to avoid
constantly looking them up in the FCPL.
- Generic property improvements:
- Added "revision" number to generic property classes to speed
up comparisons.
- Changed method of storing properties from using a hash-table
to the TBBT routines in the library.
- Share the propery names between classes and the lists derived
from them.
- Removed redundant 'def_value' buffer from each property.
- Switching code to use a "copy on write" strategy for
properties in each list, where the properties in each list
are shared with the properties in the class, until a
property's value is changed in a list.
- Fixed error in layout code which was allocating too many buffers.
- Redefined public macros of the form (H5open()/H5check, <variable>)
internally to only be (<variable>), avoiding innumerable useless
calls to H5open() and H5check_version().
- Reuse already zeroed buffers in H5F_contig_fill instead of
constantly re-zeroing them.
- Don't write fill values if writing entire dataset.
- Use gettimeofday() system call instead of time() system when
checking the modification time of a dataset.
- Added reference counted string API and use it for tracking the
names of objects opening in a file (for the ID->name code).
- Removed redundant H5P_get() calls in B-tree routines.
- Redefine H5T datatype macros internally to the library, to avoid
calling H5check redundantly.
- Keep dataspace information for dataset locally instead of reading
from disk each time. Added new module to track open objects
in a file, to allow this (which will be useful eventually for
some FPH5 metadata caching issues).
- Remove H5AC_find macro which was inlining metadata cache lookups,
and call function instead.
- Remove redundant memset() calls from H5G_namei() routine.
- Remove redundant checking of object type when locating objects
in metadata cache and rely on the address only.
- Create default dataset object to use when default dataset creation
property list is used to create datasets, bypassing querying
for all the property list values.
- Use default I/O vector size when performing raw data with the
default dataset transfer property list, instead of querying for
I/O vector size.
- Remove H5P_DEFAULT internally to the library, replacing it with
more specific default property list based on the type of
property list needed.
- Remove redundant memset() calls in object header message (H5O*)
routines.
- Remove redunant memset() calls in data I/O routines.
- Split free-list allocation routines into malloc() and calloc()-
like routines, instead of one combined routine.
- Remove lots of indirection in H5O*() routines.
- Simplify metadata cache entry comparison routine (used when
flushing entire cache out).
- Only enable metadata cache statistics when H5AC_DEBUG is turned
on, instead of always tracking them.
- Simplify address comparison macro (H5F_addr_eq).
- Remove redundant metadata cache entry protections during dataset
creation by protecting the object header once and making all
the modifications necessary for the dataset creation before
unprotecting it.
- Reduce # of "number of element in extent" computations performed
by computing and storing the value during dataspace creation.
- Simplify checking for group location's file information, when file
has not been involving in file-mounting operations.
- Use binary encoding for modification time, instead of ASCII.
- Hoist H5HL_peek calls (to get information in a local heap)
out of loops in many group routine.
- Use static variable for iterators of selections, instead of
dynamically allocation them each time.
- Lookup & insert new entries in one step, avoiding traversing
group's B-tree twice.
- Fixed memory leak in H5Gget_objname_idx() routine (tangential to
performance improvements, but fixed along the way).
- Use free-list for reference counted strings.
- Don't bother copying object names into cached group entries,
since they are re-created when an object is opened.
The benchmark I used to measure these results created several thousand
small (2K) datasets in a file and wrote out the data for them. This is
Elena's "regular.c" benchmark.
These changes resulted in approximately ~4.3x speedup of the
development branch when compared to the previous code in the
development branch and ~1.4x speedup compared to the release
branch.
Additionally, these changes reduce the total memory used (code and
data) by the development branch by ~800KB, bringing the development
branch back into the same ballpark as the release branch.
I'll send out a more detailed description of the benchmark results
as a followup note.
New internal API routines:
Added "reference counted strings" API for tracking strings that get
used by multiple owners without duplicating the strings.
Added "ternary search tree" API for text->object mappings.
Platforms tested:
Tested h5committest {arabica (fortran), eirene (fortran, C++)
modi4 (parallel, fortran)}
Other platforms/configurations tested?
FreeBSD 4.7 (sleipnir) serial & parallel
Solaris 2.6 (baldric) serial
Bug Fix
Description:
When file space was returned to the file space free-list for reuse,
occasionally raw data allocations which used space from the free-list
would overlap with the metadata accumulator and get over-written with
the cached information in the accumulator, corrupting the data.
Solution:
Check if the space about to be recycled on the free-list is going to be
used for raw data and also overlaps with the metadata accumulator cache,
avoiding using space that fits those criteria.
This fixes bug #701
Platforms tested:
FreeBSD 4.5 (sleipnir)
New feature.
Description:
Added a test to verify the correctness of information provided by
configure in H5config.h. Some information, such as SIZEOF some
types can be hardcoded by config/<machine>. This test verified
the information is indeed correct.
Currenly, only size of C language types are verified.
Platforms tested:
Eirene, regular, arabica.
Update
Description:
Changed includes of the form:
#include <hdf5_file.h>
to
#include "hdf5_file.h"
so that gcc can pick them up easier without including the system
header files since we don't care about them.
Platforms tested:
Linux
Code cleanup.
Description:
Fixed _lots_ (I mean _tons_) of warnings spit out by the gcc with the
extra warnings. Including a few show-stoppers for compression on IRIX
machines.
Solution:
Changed lots of variables' types to more sensible and consistent types,
more range-checking, more variable typecasts, etc.
Platforms tested:
FreeBSD 4.2 (hawkwind), IRIX64-64 (modi4)
New Feature
Description:
Added array datatype tests to the regression tests. These datatype
combinations are tested currently:
1-D array of atomic datatypes
3-D array of atomic datatypes
array of array of atomic datatypes
array of compound of atomic datatypes
array of compound of array datatypes
array of VL of atomic datatypes
array of VL of array datatypes
Also added a test to verify that the older style compound datatype with
array fields works correctly.
Platforms tested:
FreeBSD 4.1.1 (hawkwind)
Bug fix
Description:
"Time" datatypes (H5T_UNIX_D*) were not being stored and retrieved in
the datatype object header message correctly.
Solution:
Store endian-ness and precision in the datatype object header message and
added test to continue to track them working correctly.
This fixes bug #512.
Platforms tested:
FreeBSD 4.1.1 (hawkwind)
----------------------
./src/H5T.c
Fixed a typo in the registration of the `unsigned char' to
`unsigned long long' type conversion that caused it to not be
registered, falling back to software whenever that conversion
path was taken.
./MANIFEST
./test/Makefile.in
./test/testhdf5.c
./test/testhdf5.h
./test/theap.c [REMOVED]
./test/lheap.c [NEW]
./test/tohdr.c [REMOVED]
./test/ohdr.c [NEW]
./test/tstab.c [REMOVED]
./test/stab.c [NEW]
Removed the `t' from the front of these names and made each
test a stand-alone program following the format of most of the
other tests.
./test/big.c
Uses libh5test.a but always sets the low-level driver to 1GB
file family.
The `#if' near the top to set the data space to 8GB has been
simplified now that `long_long' is always defined and the
error message is improved when `long_long' isn't wide enough.
Cleanup code was added to the error handling.
./test/gheap.c
./test/istore.c
Uses libh5test.a. Added error cleanup code.
./test/dtypes.c
./test/h5test.c
Added 68 new tests that check hardware and software
conversions between `long long' and `unsigned long long' and
the other integer types. The tests only run on machines where
sizeof(long_long)!=sizeof(long). We test a total of 180
different integer conversions, half in hardware and half in
software.
Cut down the number of times each test is run from 5 to 1 so
it doesn't take so long. If you want to run more times
there's a constant that can be changed at the top of the file.
./test/extend.c
Removed unused variable.
./test/h5test.c
./test/h5test.h
./test/external.c
./test/fillval.c
The h5_cleanup() returns true/false so it can be used in an `if'
statement to clean up additional files.
./doc/html/Environment.html
Indented. Added HDF5_PREFIX and HDF5_DRIVER descriptions.
./src/H5P.c
Changed the trace type for the second argument from `Iu' to
`x' since it's an output parameter.
./INSTALL
Added a warning that the GNU zlib that comes with the latest
version of HDF4 is too old to use with HDF5 and must be
renamed so configure doesn't see it when `--enable-hdf4' is
used.
----------------------
./MANIFEST
Added new Pablo files HDF5record_RT.h and ProcIDs.h

./src/H5Vprivate.h
./src/H5config.h.in [REGENERATED]

./test/big.c
Added more configuration stuff for the Win32 environment. Removed all
the #ifdef WIN32 from the source and replaced them with OS-independent
stuff. Specifics follow:
Check for non-Posix.1 `st_blocks' field in `struct stat' which is used
by the big file test to decide if the file system supports holes. If
the st_blocks field isn't present then we just skip the test.
Configure checks for <io.h> <sys/resource.h> <sys/time.h> and
<winsock.h> and defines HAVE_IO_H, HAVE_SYS_RESOURCE_H,
HAVE_SYS_TIME_H and HAVE_WINSOCK_H when they're found.
Configure checks whether both <sys/time.h> and <time.h> can be
included and defines SYS_TIME_WITH_TIME if so. Otherwise include only
<sys/time.h> or <time.h> even if both exist.
Configure checks sizeof(__int64) and defines SIZEOF___INT64 to the
result or to zero if __int64 isn't defined. The source uses `long
long' in preference to `__int64'.
Removed null WIN32 definition for `inline' since such a definition
already exists in H5config.h
Protected gettimeofday() calls in debugging code with
HAVE_GETTIMEOFDAY instead of WIN32.
./src/H5F.c
./src/H5Flow.c
./src/H5Fmpio.c
./src/H5Fsec2.c
./src/H5Fstdio.h
./src/H5P.c
./src/H5Tconv.c
./src/H5private.h
Removed #include of system files from library source files and
consolodated them into H5private.h where they're protected by various
configuration macros (most of them were duplicated there already
anyway).
./test/big.c
./test/chunk.c
./test/cmpd_dset.c

./test/links.c
./test/mount.c
./test/mtime.c
./test/overhead.c
./test/ragged.c
./test/shtype.c
./test/unlink.c
Protected system #include's with #ifdef's from H5config.h.
Undefined NDEBUG since some of the tests rely on assert() to check
return values.
Removed WIN32 definitions for __unused__ since this can be controlled
by the definition of HAVE_ATTRIBUTE in H5config.h
./test/testhdf5.h
Removed the CLEAN_CMD definition because we no longer use it.
Albert's cleanup() functions replaced it.
./test/fillval.c
Initialized auto hid_t variables to fix warnings in error recovery
code when data flow analysis is turned on in compilers.
./test/h5tools.c
Initialized an auto variable to fix a compiler warning.
./test/chunk.c
./test/ragged.c
The WIN32 had some unsigned variables changed to signed because the
compiler generates warnings when coercing unsigned to double(?). I
changed them back to unsigned because they really are unsigned
quantities. If this the change was just to shut up extraneous warnings
then perhaps a compiler flag can do the same; otherwise if the
compiler generates bad code then we should supply a patch file instead
messing up source code with bug work-arounds.
./src/H5detect.c
Protected system #include's with #ifdef's from H5config.h thereby
removing a WIN32.
If getpwuid() doesn't exist (HAVE_GETPWUID) then we assume that
`struct passwd' doesn't exist either (we don't really need it in that
case).
The H5T_NATIVE_LLONG and H5T_NATIVE_ULLONG are defined in terms of
`long long' or else `__int64' or else `long' depending on what's
available.
./src/H5Flow.c
./src/H5Ofill.c
Added __unused__ to some function arguments that aren't used when
assertions are turned off.
./src/H5V.c
Changed an auto variable name in some hand-inlined code to get rid of
a warning about the variable shadowing a previous auto.
to cleanup temporary files used by that particular module.
Added a cleanup() routine to testhdf5 that calls all the other
cleanup_xxx() routines to do cleanup.
Cleanup action can be disabled either by -c (no cleanup) option
or HDF5_NOCLEANUP environment variable.
