[svn-r4842] Purpose: Feature improvement
Description:
Re-write how the free-list headers were used, to reduce the amount of space
added to each malloc request. Reduced header for array and block free
list items from 24 bytes to 8 bytes and eliminated the header for fixed-size
free list items entirely. This should reduce the amount of memory that the
library uses.
Platforms tested:
Free...
[svn-r4841] Purpose: Code improvement
Description:
Take advantage of the "MALLOC_WORKS" flag to not force malloced memory
pieces to be at least 1 byte when the malloc implementation allows
malloc(0) to work.
Platforms tested:
FreeBSD 4.5 (sleipnir) & Cray SV1 (killeen)
[svn-r4840] Purpose: New feature check
Description:
Added check to determine if malloc(0) returns a valid pointer for a
particular architecture.
Platforms tested:
FreeBSD 4.5 (sleipnir) where malloc(0) works
Cray SV1 (killeen) where malloc(0) doesn't work

[svn-r4821] Purpose:
a bug fix for release dll
Description:
change the project setting for release dll from single-threaded to
multithreaded DLL seems to make all tests pass.
For DLL testing, it should be set to multithreaded DLL anyway.

[svn-r4818] Purpose:
Small Fix
Description:

Solution:
Actually thought about the code and made it accumulate the
information in the correct way.
Platforms tested:
Linux
[svn-r4817] Description: The code was doing too many MPI_Send for the gathering.
Changed the get_minmax() to use the MPI_Allreduce routine.
Platforms tested:
modi4
[svn-r4816] Purpose:
Feature Fix
Description:
Added timer from open to close for write. Changed reporting of time
for write and read to only measure the actual read/write instead of
the open/close as well...
Platforms tested:
Linux(pp)
[svn-r4813] Purpose: Bug fix
Description:
HDfprintf was not handling Microsoft's "%I64d" extension to printf for
printing thier '__int64' type.
Solution:
Added code to properly detect and use this extension.
Platforms tested:
None! (Kent will be testing shortly)
[svn-r4811] Purpose:
Feature Add
Description:
Added the time it takes from opening the file to closing the file
(over all files).
Platforms tested:
Linux
[svn-r4809] Purpose:
Feature Fix
Description:
Instead of outputting the # of kilobytes in a transfer size, output
the total bytes. This helps when you're interested in just doing a
copy-paste type of thing for the transfer buffer size.
Solution:
Changed the output report
Platforms tested:
Linux(pp)
[svn-r4805] Purpose:
Bug fix
Description:
In several if statements, '>' was used in place of '<='. This
caused exceptions thrown inappropriately. Replaced '>' by '<='
where applicable.
Platforms tested:
SunOS 5.7 (arabica)
Windows 98
[svn-r4803] Purpose:
Feature Add
Description:
Added output which tells how large the file is (that is, the number
of dsets * number of elements in a dset * sizeof(int)).
Platforms tested:
Linux(pp)
[svn-r4802] Description: The default minimum xfer size of 1K was way too slow for
parallel file system like the PFS of Tflops. Set it to
128K to complete soon for default settings.
Platforms tested:
Tflops, modi4.
[svn-r4801] Purpose:
somehow the updated H5pubconf.h and H5config.h missed from all zip files.
recheck in.

windows 2000
[svn-r4796] Purpose: Bug fix
Description:
The value of H5_SIZEOF_SSIZE_T is not being updated to reflect the correct
size of the ssize_t typedef, if we have to define it ourselves.
Solution:
Undef H5_SIZEOF_SSIZE_T at beginning of block where we define the typedef
for ssize_t and then re-define it to the correct size when we've chosen a
size.
Platforms tested:
FreeBSD 4.5 (sleipnir)
[svn-r4795] Purpose: Extension
Description:
int64_t type is not available everywhere.
#include H5private.h which has platform dependent hooks
to define int64_t to something available.
Platforms tested:
Tflops
[svn-r4794] Purpose: Bug fix.
Description:
__int64 is not a legal type in Tflops.
Set its sizeof to 0 in the cached values.
This is a temporary fix since the real problem is
in configure which hardset __int64 to 8 for cross-compiling cases.
Platforms tested:
Tflops
[svn-r4789] Purpose: Document bug
Description:
Mention that h5dump and h5ls are not displaying variable-length string
datatype information correctly. I've also entered a more detailed bug into
the bug database.
[svn-r4783] Purpose: Small Fix Description: Changed how the list of drivers were listed from: { "driver1",
"driver2",
/* ... */
"drivern",
#ifdef FOO
"driverm"
#endif
};
to
{ "driver1"
,"driver2"
/* ... */
,"drivern"
#ifdef FOO
,"driverm"
#endif
};
since it's a nicer way of doing the same thing without the annoying
warning of an extraneous , if FOO isn't defined.
Platforms tested:
Dangermouse, Modi4, Kelgia
[svn-r4782] Purpose:
Feature Add
Description:
Added support for dumping Group Comments. This involved a
modification of the DDL as well.
Solution:
Steal code from h5ls and put it in the h5dump. The ddl.html file was
updated as normal. And a test was created...
Platforms tested:

[svn-r4773] Purpose: Regression testDescription:
Added regression test which stores variable length strings as an attribute.
Platforms tested:
FreeBSD 4.5 (sleipnir)
[svn-r4772] Purpose: Bug Fix.Description:
Equation to compute size of attribute in memory was incorrectly using the
disk's datatype (and dataspace, but that turns out not to have been the
actual issue) and when a variable length datatype was used for the
attribute, the wrong size is being computed.
Also, the variable-length datatype conversions aren't handling the
default dataset transfer property ...
[svn-r4765] Purpose: Bug fix.
Description:
FreeBSD would fail the threadsafe feature if static-exec is not on.
Solution:
Force enable-static-exec on if enable-threadsafe is on.
Also moved the chunk of FreeBSD specific code for Pthread setup
from configure.in to config/freebsd.
Also changed enable-threadsafe to check on linking pthread program.
That takes care of platforms (e.g. freebsd) ...
[svn-r4763] Purpose:
Feature Add
Description:
Needed to add the DEV_T_IS_SCALAR macro to acconfig.h so that
autoheader will propagate that to the H5config.h file.
Solution:
Added, reran autoheader
Platforms tested:

[svn-r4759] Purpose:
Bug fix
Description:
The "make depend" command wasn't propagating down into the tools/
directories.
Solution:
Added the "depend:" part to the Makefile in the tools/ subdirectory.
Platforms tested:
Linux
[svn-r4757] Purpose: Removing the DPSS (gridstorage) driver source code. Description: The DPSS (using Grid-Storage) driver is retired. Removed the configure option with-gridstorage from configure.in. Cvs remove the following files ./src/H5FDdpss.c ./src/H5FDdpss.h ./test/dpss_read.c ./test/dpss_write.c Regenerated Dependencies files (some had to be hand-edited since
'make depend' did not cover them.)
Removed reference to DPSS Virtual file driver from H5F.c.
Platforms tested:
modi4 (Parallel; -with-gass=...), eirene, arabica (fortran, cxx).
[svn-r4754] Purpose:
Feature Fix
Description:
Added the minimum, maximum, and average time and MB/s for the write
and read operations. It now prints the report out in a pretty clear
format. It also includes how many iterations were done for the
write/read operation.
Platforms tested:

[svn-r4748] Purpose: Bug fix
Description:
All processes, including those that are not part of the PIO test
sub-communicator, all attempted to run the PIO test. It resulted
in failures for those processes that are not supposed to get involved.
Solution:
The function that creates the sub-communicator also returns a
parameter indicating if the process is included in the PIO test
sub-commun...
[svn-r4747] Purpose: Bug Fix.
Description:
The H5Rget_object_type function could not get the object type for dataset
region references.
Solution:
Added a new function, H5Rget_obj_type, to replace H5Rget_object_type.
The new function requires the reference type as an additional parameter,
in order to allow queries on different reference types to be performed
correctly.
Platforms tested:
...
[svn-r4746] Purpose:
Feature Fix
Description:
Changed so the "pio_perf" module handles creating and destroying the
MPI Comm. Worked it so we get the minimum, maximum, and average times
over a set of iterations.
Solution:
Lots. Had to pull the MPI Comm code from the "pio_engine" module and
place it in the "pio_perf" module. Then worked on a way to have all
processes send their time output to process ...
