Jeff-length). Also change it such that we also have a lt_dlhandle
type -- even in the case of --disable-dlopen. Specifically, even in
the case of --disable-dlopen, we still have shell functions that use
an lt_dlhandle parameter, so we need that type, even if <ltdl.h> isn't
used.

may call calloc(large number), which causes ptmalloc2 to call mmap, which
causes us to try to dlsym for mmap, which leads to looping badness.
This commit was SVN r8461.
the ptmalloc2 memory hooks component triggers callbacks for memory
allocation / deallocation. If enabled (the default) it is only when
memory is actually obtained from or released to the OS (so little
malloc calls only trigger callbacks if sbrk is called). If disabled,
callbacks are triggered every time malloc/free/etc. is called
* It turns out that syscall and mmap aren't good friends due to the return
type of mmap and some old legacy issues with syscall functions that
take more than 5 parameters. For now, default to either loading
the symbol from glibc using dlsym or using the __m{un,}map functions.
Thanks to George for finding this.

both mmap and munmap), adjusting the configure script so that the
component will only be activated on systems that use ptmalloc2 in the
first place -- ie, Linux
* Remove the malloc_hooks component - it became an unworkable solution
once threads and such were considered.
* Remove malloc_interpose component - it never worked quite right and
was not going to be able to intercept malloc, so it wasn't going to
be useful for OMPI's purposes.
* Update tests a little bit to match recent memory hooks api
issues - still needs a bit of work.

* Install base_impl.h file when devel-headers are being installed
This commit was SVN r8200.
When compiling C++ code that includes something that looks for the C++
header file "memory" (stupid C++ headers not having .h extensions), it
goes through the header file search path, which includes $(topsrcdir)/opal,
so it finds the directory $(topsrcdir)/opal/memory/ and tries to load
that as the memory header file and all goes downhill.

originally suggested by Ralf Wildenhues, to try to speed autogen, configure,
and make (and possibly even make install). Use automake's include directive
to drastically reduce the number of Makefile files (although the number of
Makefile.am files is the same - most are just included in a top-level
Makefile.am). Also use an Automake SUBDIRs feature to eliminate the
dynamic-mca tree, which was no longer really needed. This makes adding
a framework easier (since you don't have to remember the dynamic-mca
tree) and makes building faster (as make doesn't have to recurse through
the dynamic-mca tree)

set it to empty if it isn't. __malloc_attribute__ is set in sys/cdef.h, and
some versions set it unconditionally. If sys/cdef.h is included after malloc.h,
some compilers will complain loudly. So include malloc.h at the end so that
sys/cdef.h is already included if it's going to be.

in-place already (turns out that I was wrong in thinking that it
didn't work for static components), but the logic for excluding
components was not there. This commit does a few things:
- Adds "exclude" logic, so that you can do:
mpirun --mca btl ^mvapi,openib ...
(note the "^" character -- I tried "!" but then you have to escape
it in the shell, and that was icky) which will exclude both the
mvapi and openib btl components (excluding one component means that
you are excluding all components in the list; it doesn't make sense
to include some and exclude others -- you're entire entirely
including or entirely excluding)
- Simplifies the "include" logic, so the same old stuff like this
still works:
mpirun --mca btl tcp,self ...
will only use the tcp and self btl components.
- Added more verbosity statements to make this selection process
clear.

really can't. Test for munmap, since it's the most likely to cause problems,
since it's always an interposed symbol.
The condition that usually causes problems is if libmpi was brought in as
the result of a library dependency, rather than as a -l on the link line.
The linker in this case will find malloc/free/munmap/etc. in libc, rather
than in libmpi.

relevant libraries so that when components are loaded into a parent

dynamically link to the relevant libraries, allowing the dynamic
linker to pull those libraries in at run-time, if needed

AM_INIT_AUTOMAKE, instead of the deprecated version.
* Work around dumbness in modern AC_INIT that requires the version
number to be set at autoconf time (instead of at configure time, as
it was before). Set the version number, minus the subversion r number,
at autoconf time. Override the internal variables to include the r
number (if needed) at configure time. Basically, the right thing
should always happen. The only place it might not is the version
reported as part of configure --help will not have an r number.
* Since AM_INIT_AUTOMAKE taks a list of options, no need to specify
them in all the Makefile.am files.
* Addes support for subdir-objects, meaning that object files are put
in the directory containing source files, even if the Makefile.am is
in another directory. This should start making it feasible to
reduce the number of Makefile.am files we have in the tree, which
will greatly reduce the time to run autogen and configure.

- Move the component_repository API functions out of opal/mca/base/base.h
and into opal/mca/base/mca_base_component_repository.h in order to
decrease unnecessary dependencies (e.g., before this, almost
everything in the tree depended on ltdl.h, which is unnecessary --
only a small number of files really need ltdl.h)

API is still a bit unstable and may change.
- Add a primitive "first use" component that simply has each process
"touch" the pages that they want to use, thereby [hopefully] locking
them locally to a specific processor
- Add hooks in ompi_mpi_init to enable memory affinity when processor
affinity is used.
- Added hooks in ompi_mpi_finalize to shut down memory affinity when
it was initialized during ompi_mpi_init.
- Added right hooks in ompi_info to display maffinity components.

cast the return to an int in the C++ test case, just in case.
* C++ sucks. If compiling with C++ on some GNU compiler/linker
combos, the initialize hook isn't automagically fired for the
malloc code. Add a backup setting during opal_init, which is
early enough not to cause any damage.

on all glibc systems (tested with x86 and x86_64 with a couple of C++
compilers). While not as ideal as the malloc_hooks method, it does
have the advantage of working with threads.
* Modified malloc_hooks component to properly follow prefix rule. No
functionality changes
* Make the memory framework only chose one component, and modify all
components to set priority to 20, except malloc-interpose, which is
at 10. This means that on Linux, malloc_hooks will be used unless
threads are enabled, since I think malloc_hooks is a better design
choice when we can use it

- There's still a handful of places that have orte/ #include files;

opal constants.h. This commit is the first few steps towards
that...

that were set on the command line. This was techinically exactly the
way the code was designed, but it certainly violated the Law of Least
Astonishment (even to its designer ;-) ). So now if you execute
something like this:
mpirun -mca pls_rsh_debug 1 -np 4 hello
You'll see debugging output from the rsh pls component, as you would
expect (this was not previously the case -- the MCA pls_rsh_debug
parame would be set to 1 in the 4 spawned hello processes, but *not*
in the orterun process).
More specifically, MCA parameters will be set in the orterun process
in the following cases:
- The new command line switch "--gmca" (or "-gmca") is used,
indicating that the MCA parameter is "global". --gmca also means
that that MCA parameter will be applied to all context app's. For
example:
mpirun -gmca foo bar -np 1 hello : -np 2 goodbye
The foo MCA param will be set in both the hello and goodbye
processes.
- If there is only one context app. For example:
mpirun -mca pls_rsh_debug 1 -np 4 hello
will set pls_rsh_debug to 1 in both the orterun process and the 4
spawned hello processes.
Also added a few more comments inside orterun to document a somewhat
confusing use of a state variable in a recursive case.
This commit was SVN r6764.
- new preferred API calls for registering MCA parameters are
mca_base_param_reg_{int|string} and
mca_base_param_reg_{int|string}_name.
- See opal/mca/base/mca_base_param.h for docs on new calls.
- Can now register and lookup a value at the same time.
- Can now mark a parameter "read only" at registration time
- Can now mark a parameter "internal" at registration time
- Can now associate a help message with the parameter at registration
time; displayed in the ompi_info output.
The old API calls are still available for backwards compatibility
(mca_base_param_register_{int|string}. They will eventually be
removed -- all developers are encouraged to use the new APIs from here
on out and replace any old calls with the new API.
Some params were also renamed -- the previous convention of using
"base_" as a prefix for any param that was not associated with a
component is henceforth deprecated. Instead, use one of the following
prefixes:
mca: for anything in the MCA base itself
opal: for anything in OPAL
orte: for anything in ORTE
mpi: for anything in OMPI
