Comment out the use of the "-Wpadded" flag, it's generating far too many
warnings that are impossible to correct and probably making it harder to see
other warnings that are more important.
Tested on:
Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago2)
H5_CFLAGS change
Description:
Converted a few platforms to use H5_CFLAGS to "test the waters"
Solution:
Modified a few config/* files to use H5_CFLAGS for non-essential
flags.
Platforms tested:
mir, heping
Removed -march flag
Description:
The -march optimization flag is bad in some circumstances
Solution:
Prevented HDF5 from adding the -march archicture-specific optimization
flag, so that users could have one version of HDF5 used by
several different machines.
Platforms tested:
heping (one of the few platforms that affected by this small change)
Code cleanup/update
Description:
Update compiler flags for gcc 4.1.x & start cleaning up some of the C++
compatibility
Platforms tested:
FreeBSD 4.11 (sleipnir) w/gcc 4.1 and/or g++
Bug fix
Description:
Tone down the optimization flags for gcc 4.2.x in the same way as we
do for all the other gcc 3/4 builds, to avoid datatype conversion issues.
Platforms tested:
FreeBSD 4.11 (sleipnir) w/gcc 4.2
Not tested by h5committest
Description:
Add source code copyright notice; comment symbols vary by type of file.
Platforms tested:
No changes that should cause any problems. Nonetheless, the tree will
be checked out fresh and tests run immediately post-commit.
Update flags
Description:
Update gcc compiler flags to support the early gcc 4.0 snapshots available
on sleipnir
Platforms tested:
FreeBSD 4.10 (sleipnir) w/gcc 4.0 snapshot
Too minor to require h5committest
Code cleanup/bug fix
Description:
Remove the undocumented "$NOFP" shell variable which would allow production
builds without removing the stack frame. This was cascading between C and
FORTRAN builds and causing problems.
Solution:
Hard-code removing the stack frame for now. Users would have needed to
read the configure scripts anyway, so there's not really much benefit to the
extra knob. Users who need this functionality (production builds with stack
frames) are debugging probably, so they will need to modify the script and
build their own version of the library now.
Platforms tested:
Linux 2.4 (verbena)
Too minor to require h5committest
Bug fix
Description:
It uses the value of $ARCH as a gcc option but the linux clusters
at NCSA define $ARCH as environment variable with values that are
not a valid compiler option. That caused the configure to fail
because it was not able to compile at all.
Solution:
Change ARCH to lower case $arch (convention dictates environment
variables are upper cases.) Also preset $arch to null and do not
honor any pass it values.
Platforms tested:
Attempted to run h5committest but sol was failing due to /tmp
filled. Copper and verbena passed. Also passed in TG-NCSA.
Misc. update:
Code cleanup & addition
Description:
Add new warnings for gcc 3.4.x
Re-work production mode compile flags to work better.
Platforms tested:
FreeBSD 4.10 (sleipnir)
h5committest
Bug fix
Description:
Fix build on sparc64 platform for FreeBSD by modifying the config/gnu-flags
to not insert '-march=i686' on non-Intel platforms. (This change allows HDF5
to run correctly on all five of the main FreeBSD platforms... :-)
Platforms tested:
FreeBSD 4.9 (sleipnir)
h5committest not run since it's a FreeBSD-specific fix.
improvement.
Description:
Created an entry for 2.96 and added -Wno-long-long to the CFLAGS
to suppress the thousands of 'long long' warnings because we are
using it and we know it is not in the C89 standard.
Platforms tested:
Only in verbena.
Misc. update:
Bug fix
Description:
Update gcc 3.4 flags to reduce optimization level to the same settings
as for gcc 3.0-3.3 due to code generation bugs at higher optimization levels.
Platforms tested:
FreeBSD 4.9 (sleipnir)
Bug fix
Description:
Reduce optimization level from -O3 to -O for gcc 3.*, since it seems to
be generating bad code for the atomic type conversions now...
Platforms tested:
FreeBSD 4.9 (sleipnir)
Linux 2.4 (eirene, verbena)
h5committest not necessary, this is a GNU-only change.
Update
Description:
Revamped the configuration system. The configurations for the Fortran
and C++ libraries are no longer separate from the "main"
configuration system. This involved removing the "configure*" and
"aclocal.m4" files from the fortran/ and c++/ subdirectories. Also
merging settings in the config/ subdirectories into the main config/
subdirectory.
Fortran header files had to be modified a little for Linux. It was
checking if it was a Linux machine by some #defines, however with the
-std=c99 switch, these defines weren't there. I added a check for
some other ones which should be there whether the -std=c99 switch is
used or not.
Platforms tested:
Verbena (Fortran & C++)
Sol (Fortran & C++)
Copper (Fortran & C++)
Modi4 (Parallel, Fortran, & C++)
Misc. update:
Code cleanup
Description:
Remove special optimization and debugging flags for obsolete versions of
gcc.
Platforms tested:
FreeBSD 4.8 (sleipnir)
h5committest not needed.
Initial pass for gcc3.3 support
Description:
Added section for gcc 3.3+ and cleaned up the gcc 3.2+ section a little.
Platforms tested:
FreeBSD 4.8 (sleipnir) w/gcc 3.3 snapshot
Triple check unneeded.
Bug fix.
Description:
-O2 -finline-functions still causes production builds on eirene to fail.
Solution:
Downgrade optimization on gcc 2.95.x (x<3) to -O -finline-functions
Platforms tested:
Linux 2.2 (eirene)
Bug fix w/gcc 2.95.x where x<3
Description:
-O3 optimization level causes problems for gcc 2.95.2 on eirene
Solution:
Only enable -O3 if using gcc 2.95.x (where x>=3) or gcc 3
Otherwise, use older setting of -O2 -finline-functions
Platforms tested:
FreeBSD 4.7 (sleipnir)
Linux 2.2 (eirene)
Code cleanup
Description:
Clean up miscellaneous warnings which have crept into the code.
Fix "_POSIX_C_SOURCE not defined" warning on FreeBSD.
Adjust gcc compiler flags to be more concise for production mode.
Refactor the H5O code so that there is a stronger boundary between code
in the H5O package and code in the library which just calls H5O routines.
Platforms tested:
Tested h5committest {arabica (fortran), eirene (fortran, C++)
modi4 (parallel, fortran)}
FreeBSD 4.7 (sleipnir) serial & parallel and gcc 2.95.4 & gcc 3.2.2
Misc. update:
Update MANIFEST if you add or remove any file.
Cleanup
Description:
Cleanup gcc cases to be more general about gcc 3.x, now that gcc 3.2 has
been released.
Platforms tested:
FreeBSD 4.6 (sleipnir) - not a significant enough change to worry about
multi-platform testing.
Bug Fix
Description:
Placed quotes around strings which could be empty so that the shell
script doesn't complain to us about "too many arguments for test"
problems.
Platforms tested:
Linux
Configure cleanup
Description:
Neaten up file a bit more...
Platforms tested:
Linux 2.2 (eirene) with gcc 2.95.2 and Solaris 2.6 (baldric) with gcc 2.8.1
Configure cleanup
Description:
Fine-tune the gcc version checks a bit more...
Platforms tested:
FreeBSD 4.5 (sleipnir) with gcc 2.95.3 and gcc 3.1 (prerelease) and
Solaris 2.6 (baldric) with gcc 2.8.1
Configuration improvements
Description:
Added more warning flags to gcc builds, especially with gcc 3+. Also, added
the -Wno-long-long flag to gcc builds to turn off the annoying "long long"
warnings.
Platforms tested:
FreeBSD 4.5 (sleipnir) with gcc 2.95.3 and gcc 3.1 (prerelease)
Purpose:
Feature Addition
Description:
Added support for gcc 3.0.x. GCC 3.0.x supports the C99
specification. The "-std=c99" gets rid of those annoying "warning
long long not supported by ANSI standard" messages.
Platforms tested:
Linux and gcc 3.0.1
Bug fix... (sorta)
Description:
Added --enable-linux-lfs configure flag to have better control over whether
the enable large file support on Linux machines. Also removed the
-malign-double flag for gcc since it can potentially cause errors which
are difficult to detect.
Platforms tested:
Linix 2.2 & 2.4 (eirene and dangermouse)
Code cleanup
Description:
Get ready for adding C99 extensions sometime in the future.
Solution:
Added some comments to the gcc flags..
Platforms tested:
Linux (eirene), FreeBSD 4.3 (hawkwind)
Better Mouse Trap^W^WBug Fix
Description:
Instead of having the large file support stuff be in the
config/gnu-flags directory, I added it to the configure.in file so
that it first checks for the syscall ``getdents64()''. If it finds
it, then it removes the ``-malign-double'' flag if the GCC compiler
is 2.95.x since this flag doesn't play well with the LFS stuff.
Solution:
Added test for getdents64(), if found it removes the -malign-double
flag if the compiler is 2.95.x. This is done in the configure.in
file. The gnu-flags file is returned to normal. A new field is added
to the H5config.h.in file because of the getdents64 check.
Platforms tested:
Linux
Bug Fix
Description:
Linux does actually support 64 bit files (those greater than 2GB),
you just have to defined a bunch of, seemingly meaningless, macros in
order to coax glibc to work with you. 64 bit file support is in the
2.3 and above kernels by default. For lower, well...upgrade or
something. The one weird thing, the "-mdouble-align" flag was causing
hdf5 to barf when the large file support was compiled in there. It
has something to do with the structures and their alignment or
something. Very weird.
Solution:
Added a test to see if we're on a Linux boxen with kernel >2.3 and if
so then specify the flags for LFS support. Removed the -mdouble-align
flag if we do use LFS support since it causes damage.
Platforms tested:
Linux (Dangermouse)
Code cleaning
Description:
Moved all gcc compiler flags into the config/gnu-flags file and re-added
the warning flags removed during the beta testing.
Platforms tested:
FreeBSD 4.2 (hawkwind)
Config cleanup
Description:
In production environments, the optimization flag for gcc was set to
-O6, which has some code-generation problems in certain environments.
Solution:
Turned optimizations down to -O2, which is still pretty bleeding edge.
Platforms tested:
FreeBSD 4.2 (hawkwind)
Feature Fix
Description:
This checks before printing the warning message about hsizet type if
the user specified --disable-hsizet on the command line.

----------------------
This extensive change is the virtual file layer implementation. I've
ported and tested the sec2, family, and core drivers and only ported
the mpio driver (Albert will test it). So if you need MPIO I would
recommend sticking with the previous version for a while.
You will get a few compile warnings about split and stdio drivers not
being implemented and possibly tracing information not inserted in
some of the drivers. You can safely ignore them but I plan to fix
them.
I'm still working on the split driver because I just realized that it
needs a part of the VFL that isn't written yet.
Documentation is being updated also because there were some minor
changes (mostly just name changes). It should be available on my web
site later this week.

Modified to work with the virtual file layer by calling H5FD_*
functions instead of H5F_low_* functions and by passing file
access and data transfer properties by object ID instead of
pointer.
Changed H5D_transfer_t to H5FD_mpio_xfer_t since the
COLLECTIVE vs. INDEPENDENT transfer mode is specific to the
MPIO file driver.
Moved MPIO-specific stuff into the MPIO driver.
./src/H5B.c

./src/H5E.c
./src/H5Epublic.h
Added major error number H5E_VFL for virtual file layer
related errors.
./src/H5F.c
./src/H5Fprivate.h
Changed the logic that controls whether the boot block is
written. Instead of assuming that the first call to write the
boot block is only to allocate space, I've added a function
argument which makes this explicit.
Changed the way files are compared so that a driver-defined
comparison function can be called. Files which belong to
different drivers are always considered different.
Removed H5F_driver_t since file drivers are now identified by
object ID instead of a special non-user-extendible datatype.
Removed all the hard-coded low-level file properties which
have been replaced by the various file drivers.
./src/H5I.c
./src/H5Iprivate.h
Added the H5I_inc_ref() which was removed a few months ago
since we finally have a use for it.
./src/H5Ipublic.h
Added the H5I_VFL object ID type to identify file drivers in
the virtual file layer.
./src/H5MF.c
./src/H5MFprivate.h
Moved all the allocation/deallocation code into the virtual
file layer which allows file drivers to override much of it.
./src/H5P.c
./src/H5Ppublic.h
Moved file driver-specific code into the various file driver
files.
The H5Pcopy() and H5Pclose() functions make calls into the
virtual file driver to manage the memory for driver-specific
file access and data transfer properties.
./src/H5private.h
./src/H5public.h
The `haddr_t' type is now public.
./test/tfile.c
Added a few more comments.
----------------------
NOTE: These bug fixes but have been applied only to the 1.3 branch per
Albert's request.
./config/gnu-flags [1.3]
Added support for gcc-2.95 by adding full optimization and
debugging flags and applied a patch from Marcus Daniels.
./src/Makefile.in [1.3]
Removes the `libhdf5.settings' file for `make clean'.
----------------------
./tools/h5ls.c
Added a `--address' (`-a') switch which causes h5ls to display
file addresses for raw data. For contiguous datasets it's just
a nice simple number, but for chunked datasets it's a list of
logical dataset coordinates, file addresses, filter masks, and
storage sizes.
Changed `--dump' switch to `--data'.
./src/H5D.c
./src/H5F.c
./src/H5Fprivate.h
Enhanced the indexed-storage B-tree iterator so it can dump
raw data addresses (and other info) to the standard error
stream.
Added H5Ddebug() so h5ls has a way to dump addresses for
datasets. I'm not sure what else this API function should do,
so I think we should discuss it before we document it. So far,
h5ls is the only thing that uses it, and we can easily change
that.
./src/H5Tconv.c
./test/dtypes.c
Finally had a chance to verify Paul's H5T_conv_s_s (general
string to string conversions) bug fixes and incorporate them
into H5T_conv_f_f (general floating-point to floating-point
conversions) and H5T_conv_i_i (general integer to integer
conversons). Thanks Paul.
./src/H5D.c
./src/H5S.c
./src/H5Sprivate.h
Added performance timers around data space read and write
callbacks. They were already there for the gather/scatter
callbacks.
The timings for read/write callbacks are displayed along with
gather/scatter when data space debugging is turned on.
./bin/iostats
Updated to print totals. Added a `--fast' option that doesn't
do any output except the totals and is much faster.
./bin/trace
Changed __unused__ to UNUSED to match source code.
./config/gnu-flags
Updated error message for pgcc. I've sent bug reports to the
pgcc people but the new version still has the same bug.
./configure.in
./config/conclude.in
./config/depend.in
Fixed dependencies for non-GNU makes when run in a directory
other than the hdf5 source tree.
Updated GNU `make dep' rules to copy the distributed
dependencies for non-GNU makes into the source tree when run
in some other directory.
----------------------
./config/depend.in
Fixed automatic dependencies. We were storing dependencies for
*.o files instead of *.lo files after shared libraries were
added.
./config/gnu-flags
./config/linux-gnulibc1
Moved `-march=pentiumpro -mcpu=pentiumpro -malign-double' from
the linux file to this file and caused it to depend on the CPU

./test/istore.c
Added an H5Dget_storage_size() function that reports the
amount of storage allocated for raw data in a dataset.
Changed H5D_xfer_* to H5F_xfer_* because these properties are
more general than datasets. This also allows some of the
lower-level I/O functions to get this information easier.
./src/H5S.c
./src/H5Sall.c
Added two new functions H5S_all_read() and H5S_all_write()
which are optimizations that copy data directly between file
and memory without having to go through the scatter gather
step. This knocks quite a bit of time off the I/O and
reading/writing entire datasets is a fairly common operation.
./tools/h5ls.c
Reports the logical size of data, the allocated size of data,
and the percent utilization.
./MANIFEST
Removed old pablo files, added new files. Snapshots should now
start to work again.
./src/H5D.c
