Bug Fix/Code Cleanup/Doc Cleanup/Optimization/Branch Sync :-)
Description:
Generally speaking, this is the "signed->unsigned" change to selections.
However, in the process of merging code back, things got stickier and stickier
until I ended up doing a big "sync the two branches up" operation. So... I
brought back all the "infrastructure" fixes from the development branch to the
release branch (which I think were actually making some improvement in
performance) as well as fixed several bugs which had been fixed in one branch,
but not the other.
I've also tagged the repository before making this checkin with the label
"before_signed_unsigned_changes".
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel & fphdf5
FreeBSD 4.10 (sleipnir) w/threadsafe
FreeBSD 4.10 (sleipnir) w/backward compatibility
Solaris 2.7 (arabica) w/"purify options"
Solaris 2.8 (sol) w/FORTRAN & C++
AIX 5.x (copper) w/parallel & FORTRAN
IRIX64 6.5 (modi4) w/FORTRAN
Linux 2.4 (heping) w/FORTRAN & C++

*
|
|
* Purpose: Create a dataset with a null dataspace and an attribute
|
|
* with a null dataspace.
|
|
* This program is used to create the test file `tnullspace.h5' which
|
|
* has dataspaces stored in the newer (version 2) style in the object headers.
|
|
* To build the test file, this program MUST be compiled and linked with
|
|
* the hdf5-1.7+ series of libraries and the generated test file must be
|
|
* put into the 'test' directory in the 1.6.x branch of the library.
