Bring r17546:17895 from trunk to revise_chunks branch. Changes to
fixed and extensible array dataset chunk indexing code to accommodate changes
to private APIs in those interfaces. Also, other adjustments to source code
and expected output in response to changes on the trunk.
Tested on:
FreeBSD/32 6.3 (duty) in debug mode
FreeBSD/64 6.3 (liberty) w/C++ & FORTRAN, in debug mode
Linux/32 2.6 (jam) w/PGI compilers, w/default API=1.8.x,
w/C++ & FORTRAN, w/threadsafe, in debug mode
Linux/64-amd64 2.6 (smirom) w/Intel compilers, w/default API=1.6.x,
w/C++ & FORTRAN, in production mode
Solaris/32 2.10 (linew) w/deprecated symbols disabled, w/C++ & FORTRAN,
w/szip filter, in production mode
Linux/64-ia64 2.6 (cobalt) w/Intel compilers, w/C++ & FORTRAN,
in production mode
Linux/64-ia64 2.4 (tg-login3) w/parallel, w/FORTRAN, in debug mode
Linux/64-amd64 2.6 (abe) w/parallel, w/FORTRAN, in production mode
Mac OS X/32 10.6.2 (amazon) in debug mode
Mac OS X/32 10.6.2 (amazon) w/C++ & FORTRAN, w/threadsafe,
in production mode

|
|
* Purpose: Create a file with a dataset who's raw data immediately follows
|
|
* its object header, so that when the dataset is unlinked from its parent
|
|
* group, a speculative read of the object header would get the raw data
|
|
* into the metadata accumulator, "polluting" it.
|
|
* To build the test file, this program MUST be compiled and linked with
|
|
* the library on the trunk as of when this file is checked in.
