Bug Fix
Description:
On HP-UX platforms, the "open()" function needs to specify that the
file being created has permissions S_IRWXU, which means that it gives
read/write/execute permissions to the user who created the file (how
nice of it!).
Solution:
Added the S_IRWXU flag to the open() function call.
Platforms tested:
HP-UX 11
Arabica,
Modi4,
Verbena

Code Improvements/Bug Fixes
Description:
Comparison of equality of a double/float variable to 0.0 is not
guaranteed to work and is bad practice.
Solution:
Test that the absolute value of the variable is < a very small
positive number.
Platforms tested:
Modi4 (Parallel & Fortran)
Verbena (C++ & Fortran)
Arabica (Fortran)

Bug Fix
Description:
The "mkstemp()" function isn't as portable as I hoped it would be (it
fails on Crays and other beasts).
Solution:
Removed and just use a fixed filename instead.

Solaris w/ zlib
Irix w/ zlib

Update, Bug Fix, and Feature Add
Description:
- Updated how AC_{ENABLE,WITH} help messages were being generated.
Autoconf now gives you an AC_HELP_STRING macro to use to create
them.
- Fixed the problem with Linux LFS on RedHat 7.3 machines. It wasn't
finding getdents64(), so we can't rely on that being present
anymore...
- Added GPFS detection and setting.
- Updated how compression is specified. It's no longer necessary to
test for HAVE_ZLIB_H, HAVE_LIBZ, and HAVE_COMPRESS2. The one macro
{H5_}HAVE_COMPRESSION takes care of all of these.
Solution:
Changed the check for Linux LFS from looking for getdents() to
looking at the version number of the kernel (using the uname -r
command). You can still override with the --enable-linux-lfs switch
if you really believe that your <2.4 kernel has LFS support.
Platforms tested:
Linux (2.2 and 2.4)

Feature Add
Description:
Allow you to specify the percentage you'd like a random buffer to be
compressible. It can go from 0% (non-compressible) to 100%
(completely compressible).
Platforms tested:
FreeBSD

Feature Add
Description:
Use the /dev/urandom device for random data if it's available. (That
is stat() doesn't return a -1 when ran on it). Use random() otherwise.
Platforms tested:
Linux, FreeBSD

The test for compression needed to be reversed.

Feature Update
Description:
It now writes an uncompressed version of the file out. The first
tests didn't look all that wonderful. Here is a typical output:
Buffer size == 1MB
Uncompressed Write Time: 0.55s
Uncompressed Write Throughput: 116.00MB/s
Compressed Write Time: 8.76s
Compressed Write Throughput: 7.31MB/s
Platforms tested:
Linux

Compress I/O Test Add
Description:
This is the initial check-in of the compress I/O test. It will write
out compressed buffers to a file.
I need to implement a write of uncompressed data first for
comparison...

Linux
