Bug fix
Description:
The t_mpi used to fail and exit if any error detected.
That aborted other process in a "make check" situation.
Solution:
Introduced a new error verification as INFO. INFO is for
information only. It does not increase nerrors count.
The program always exits with 0.
Platforms tested:
eirene with mpich.
bug fix
Description:
The last reported problem that the parallel example program
in examples could not be compiled, could not be duplicated
again. I guessed maybe Rushad mistook the compile warning
messages as error messages. Just a guess.
Furthermore, the changed examples/Makefile.in and configure.in,
did not work for the parallel case. The examples/ph5example.c
was never included for compiling.
Solution:
Removed the fix in configure.in, put ph5exmple directly back
in the examples/Makefile.in but put it in a variable for
easier future maintenance. Also, easier to identify the
parallel examples too.
Platforms tested:
Eirene, both serial and parallel modes.
Small code addition
Description:
Addition logging of seeks during read operations (writes were already
logging seeks). Also added a few asserts to check memory allocations...
Platforms tested:
Solaris 2.6 (baldric)
Purpose:
Bug fix
Description:
All examples used "FILE" string in the #define preprocessor
directive. That caused error on Windows platforms since
FILE is a structure returned by fopen calls.
Solution:
Changed "FILE" to "H5FILE_NAME"
Platforms tested:
Linux (eirene)
Purpose:
HPUX 11.00 port
Description:
Redundant USE statements triggered a bug in the HP F90 compiler.
Solution:
Source code was rearranged to avoid redundancy: definitions of the
object and dataset region reference types were moved from H5Rff.f90
to H5f90global.f90; "USE H5R" statement was removed from H5Rff.f90.
Now H5Rff.f90 uses "USE H5GLOBAL" statement only as the rest of
the modules.
Platforms tested:
HPUX 11.00 (kelgia), Solaris 2.7 (arabica)
Purpose:
Bug fix
Description:
The MPI I/O calls were not being traced.
Solution:
Changed the calls to traceEvent from the MPI I/O tracing to HDFtraceEvent
in the Pablo Traceing.
Platforms tested:
Irix 32 and 64, HP VClass 32 and 64 bit and Solaris
Bug fix
Description:
This file is not C++ friendly/compliant because the protocols
are not bracketed by the #ifdef __cplusplus macro. This was
discovered by a user attempting to use C++ with enable-parallel.
Solution:
Though we are not supporting C++ in parallel mode yet, it is
simple to add the macro bracket. It would help if C++ is supported
in the future.
Platforms tested:
modi4 (64,n32) and eirene (mpich).
Purpose:
Removing known problem
Description:
Removed the note about the c++ test compresion failed on Linux.
This was meant to be in the RELEASE.txt of 1.4 branch, but I put
it here by mistake. The problem is fixed now, I'll make a note
in the correct RELEASE.txt.
Platforms tested:
Keeping my fingers crossed on this!
Code Simplification
Description:
H5Pget_class() was being called from the H5.c module. Changed it so
that it calls H5P_get_class() instead. Also, the H5Pget_class() and
H5P_get_class() functions were identical. Changed so that
H5Pget_class() calls H5P_get_class().
Platforms tested:
Linux
Small Fix
Description:
Don't delete the /tmp/${USER,LOGIN} directory when we're done with
it. Also, only do the /tmp/${USER,LOGIN} if this is a parallel
configured library.
Solution:
Removed the removal of the /tmp/${USER,LOGIN} directory and added
checks to determine if we're in a parallel configured library before
munging the filename...
Platforms tested:
Linux
Feature Add
Description:
Added the feature (not a bug, a FEATURE!) that, if the person has the
env variables USER or LOGIN set, then it will place the temporary
files in the "/tmp/$USER" or "/tmp/$LOGIN" directory (in that order).
This is only if the prefix the user gives is the default one "/tmp".
After the tests are finished, it will remove the directory for the
user.
Platforms tested:
Linux
Test Addition
Description:
I added a small test to determine if the MPI library has a working
version of the MPI_Get_count() function. If it does, then I define
the macro:
MPI_GET_COUNT_WORKS
This should (hopefully) take care of the kludges in H5FDmpio.c...
NOTE: This isn't implemented in the H5FDmpio.c file since I don't
know the code in there and don't know which solution will work. Also,
the test program I put into the configure script needs to be checked
on a platform which does have a working MPI_Get_count()
function...I.e., this is just a first stab.
Platforms tested:
Linux
Bug fix
Description:
Some mpi.h already includes MPI-IO definitions in it (e.g., SGI,
SP2). Made the #include of mpio.h be dependent on whether some
MPI-IO constant is already defined or not.
Platforms tested:
modi4 (IRIX64) and IBM SP2.
Changed MPI_File_seek then MPI_File_write or MPI_File_read to just
MPI_File_write_at and MPI_File_read_at. Some compiler, e.g., IBM
mpcc_r does not support MPI_File_seek and MPI_File_read or MPI_File_write.
This is a better measurement against HDF5 performance since HDF5
uses MPI_File_write_at and MPI_File_read_at all the times.
It is a more thread safe to use MPI_xxx_at than the other seek then
read/write approaches.
Platforms tested:
modi4 (irix64 parallel), IBM sp2.
Purpose:
Bug fix
Description:
There was a typo in the gif.h path that I overlooked first time.
Solution:
Fixed a typo. bin/chkmanifest does not complain anymore.
Platforms tested:
baldric
Purpose:
Bug fix
Description:
Rushabh added new directory tools/gifconv to CVS. He also modified
MANIFEST, but bin/chkmanifest complains this file.
Solution:
I will try to delete gif.h and then to add it once more.
Purpose:
Adding new feature
Description:
Added gif2h5 and h52gif conversion utilities
Solution:
The utilites follow the framework built for the gif2hdf and hdf2gif
utilities for hdf4. The main files modified were those that read the
H5 file and those that write H5 file. In the future, if you wish to
continue with the framework and extend it to .png or some other fileformat
the main files to edit will be the gif reader and writer.
One point to note with h52gif. You have to specify the exact location of
the image and the palette that it links to. You can choose not to specify
a palette (uniform grayscale chosen in this case) but you must specify
image location. In the future, someone could edit the readhdf.c source
to enable the reader to parse the hdf file and select all images with
corresponding palettes.
Platforms tested:
modi4 , eirene , hawkwind , arabica , Ren (NT 4.0) , Personal box (win2k)
Replace Kludge with Another Kludge
Description:
The MPI_Get_count function isn't found on most systems. We need to
replace this with a configure call which checks and defines the macro
H5_HAVE_MPI_GET_COUNT or something.
Solution:
If-def'ed out the code for everyone (since H5_HAVE_MPI_GET_COUNT is
never defined anywhere).
Platforms tested:
SDSC HP N9000
Bug Fix
Description:
FILENAME_MAX is short on some systems. It's better to use PATH_MAX
which tends to be longer (we hope).
Solution:
Removed FILENAME_MAX and replaced it with PATH_MAX instead.
Platforms tested:
Skinner (SDSC HP N9000).
Cosmetic adjustment
Description:
Changed Version information from just "HDF5 version ..."
to "HDF5 library version" since this is really about a
library implementation.
Platforms tested:
eirene (used "h5vers -s ..." to see the effect.)
Purpose:
Bug fix
Description:
There was a syntax error on Windows, and I fixed it long time ago but forgot
to check this file into CVS.
Solution:
Fix the error.
Platforms tested:
Windows98
