keep the resulting tm_event_t that is generated because the back-end
TM library actually caches a bunch of stuff on it for internal
processing, and doesn't let go of it until tm_poll().
tm_event_t's are similar to (but slightly different than)
MPI_Requests: you can't do a million MPI_Isend()'s on a single
MPI_Request -- a) you need an array of MPI_Request's to fill and b)
you need to keep them around until all the requests have completed.

using a pty for everything, which drops all buffered data on the floor when
close() is called on the daemon side, meaning EOF has some issues. Instead,
do the same thing we do for other starters that use the fork() pls -- use
a pipe/fifo for stdin and stderr and a pty for stdout. This is good enough
for what we need and avoids most of the issues with ptys.

* num_children should really be an int instead of size_t
since 'size_t' is not signed and num_children can (in rare cases)
drop below 0, and don't want it to roll around to MAX_INT or some
such.
* I figured out that this problem only happened to me because I use
the pls_fork_reap_timeout MCA parameter and thus the only time that
the code in pls_fork_module.c to waitpid is executed is if this is
not set to 0 (I had it set to 1 to give my procs time to exit). I
adjusted the loop from while{...} to do{...}while; so that it is
executed at least once for consistency.
* de-register the SIGCHILD callback for the pid before we attempt
to kill it, so that we don't leave the door open for both the
waitpids (the one in the callback, and the one in this function)
to race to see who can wait on the child.
* Move the 'thread release' to outside the for loop for a bit of an
optimization, and always set the value to 0 since we want to
finish after this function.
* Added a help message for the case when we can't send a kill()
signal to the process. Should never happen, but all is possible
in the wild wild west of HPC.
This commit was SVN r10666.
When we force an application to terminate (via CTRL-C to mpirun)
we send an out-of-band message to the orted to reap its children.
the fork PLS was doing an internal waitpid but never releasing or
updating the information and signaling the condition variable. So
the fork PLS callback for SIGCHLD registered with the event library
and this waitpid are in a bit of a race to 'waitpid' for the children.
Since the PLS callback was the only one that handled the signal properly
when it 'won' then things were great -- as in the normal termination case.
But when it 'lost' -- as in the abnormal termination case -- the orted
never received the proper signal that its children had gone away.
We want to preserve the internal fork PLS callback since it allows
for a timeout while waiting for the child, which the event library
won't do.
This allows both to exist, and behave properly.
This was introduced in r9068.
The ticket is still open since the orted's hang in other situations
still. This is a fix for one of the causes.

This commit was SVN r10641.
After seeing the uglyness that is removing directories in the
codebase I decided to push down this to the OPAL by extending the
opal/os_create_dirpath.(c|h) to contain some more functionality.
In this process I renamed 'os_create_dirpath' to 'os_dirpath' since it
is a bit more general now.
Added a few functions to:
- check if an directory is empty
- check to see if the access permissions are set correctly
- destroy the directory at the end of the dirpath
- By using a caller callback function (a la Perl, I believe)
for every file, the caller can have fine grained control over
whether a specific file is deleted or not.
This simplifies things a bit for orte_session_dir_(finalize|cleanup)
as it should no longer contain any of this functionality, but uses
these functions to do the work.
From the external perspective nothing has changed, from the
developer point of view we have some cleaner, more generic code.
This commit was SVN r10640.
1. Changed the RMGR and PLS APIs to add "signal_job" and "signal_proc" entry points. Only the "signal_job" entries are implemented - none of the components have implementations for "signal_proc" at this time. Thus, you can signal all of the procs in a job, but cannot currently signal only one specific proc.
2. Implemented those new API functions in all components except xgrid (Brian will do so very soon). Only the rsh/ssh and fork modules have been tested, however, and only under OS-X.
3. Added signal traps and callback functions for SIGUSR1/2 to orterun/mpirun that catch those signals and call the appropriate commands to propagate them out to all processes in the job.
4. Added a new test directory under the orte branch to (eventually) hold unit and system level tests for just the run-time. Since our test branch of the repository is under restricted access, people working on the RTE were continually developing their own system-level tests - thus making it hard to help diagnose problems. I have moved the more commonly-used functions here, and added one specifically for testing the SIGUSR1/2 functionality.
I will be contacting people directly to seek help with testing the changes on more environments. Other than compile issues, you should see absolutely no change in behavior on any of your systems - this additional functionality is transparent to anyone who does not issue a SIGUSR1/2 to mpirun.

Difference is that instead of hard-coding the strings "/lib" and
"/bin" in to append to the prefix, we append the basename of the local
libdir and bindir. Hence, if your libdir is $prefix/lib64, we'll
append /lib64 to construct the remote node's LD_LIBRARY_PATH (etc.).
Also appended the orterun.1 man page to include a description of
--prefix, how it is constructed, what it handles / what it does not,
etc.

argv[0] and the cwd on the target node (i.e., the node where the
executable will be running in all systems except BProc, where the
searches are run on the node where orterun is invoked).
- fork pls now does cwd and argv[0] search in orted
- bproc pls does cwd and argv[0] search in orterun
- cwd behavior slightly different:
- if user specifies a -wdir to orterun, we chdir() to there; if we
can't for some reason, abort
- if user does not specify a -wdir, try to chdir() to the dir where
orterun was invoked. If we can't for some reason (e.g., it
doesn't exist on the target node), then try to chdir($HOME). If
we can't do that, then just live with whatever default directory
we were put in.

The INIT counter is supposed to be adjusted when the processes are mapped - this is now done correctly.
The LAUNCHED counter is supposed to be adjusted when the pls sets the process pid info into the registry and changes the state to LAUNCHED. This could probably be changed to have that function use the set_proc_soh API, but this fixes the problem for now.

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)

oversubscribed on a node. And thus whether to call sched_yield or not.
The value of node->node_slots_inuse does not currently represent the number of
slots actually in use, at the moment. This is actually a bug in the RAS/RMAPS
base components, but the fix for that specific bug is bigger than we want to
address at the moment (but will certianly do so in the near future).
Since we cannot trust this value, use the total number of mapped processes
(which was properly set by the RMAPS component upon mapping -- Just not
properly propagated back to the registry's node segment) from the process
mapping.
In addition to this change I cleaned up a couple of the debug messages. It
seems that TM and RSH are the only two directly effected by this. SLURM
would be if that section of code wasn't currently inactive, but put the fix
in for prosparity.

The logs from this branch are much more descriptive than I will put
here (including a *really* long description from last night). Here's
the short version:
- fixed some broken implementations in ras and rmaps
- "orterun --host ..." now works and has clearly defined semantics
(this was the impetus for the branch and all these fixes -- LANL had
a requirement for --host to work for 1.0)
- there is still a little bit of cleanup left to do post-1.0 (we got
correct functionality for 1.0 -- we did not fix bad implementations
that still "work")
- rds/hostfile and ras/hostfile handshaking
- singleton node segment assignments in stage1
- remove the default hostfile (no need for it anymore with the
localhost ras component)
- clean up pls components to avoid duplicate ras mapping queries
- [possible] -bynode/-byslot being specific to a single app context

If you use --prefix and then "-x LD_LIBRARY_PATH", the rsh pls would
take great pains to ensure that PATH and LD_LIBRARY_PATH were setup
correctly on the local and remote nodes, but then the fork pls would
blitely overwrite LD_LIBRARY_PATH with what the user exported (i.e.,
most likely without our prefix). This patch takes care of that -- the
fork pls examines the incoming environment, and if it sees PATH or
LD_LIBRARY_PATH, it re-prefixes those variables.

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.

- This was an empty file. moved the orte_ras_node_t from base/ras_base_node.h

- Changed the name of orte_ras_base_node_t to orte_ras_node_t to match the
naming mechanisms in place.
ras.h
- Exposed 2 functions:
- node_insert:
This takes a list of orte_ras_base_node_t's and places them in the Node
Segment of the GPR. This is to be used in orte_init_stage1 for singleton
processes, and the hostfile parsing (see rds_hostfile.c). This just puts
in the appropriate API interface to keep from calling the
orte_ras_base_node_insert function directly.
- node_query:
This is used in hostfile parsing. This just puts in the appropriate API
interface to keep from calling the orte_ras_base_node_query function
directly.
- Touched all of the implemented components to add reference to these new
function pointers
ras_base_select.c & ras_base_open.c
- Add and set the global module reference
rds.h
- Exposed 1 function:
- store_resource:
This stores a list of rds_cell_desc_t's to the Resource Segment.
This is used in conjunction with the orte_ras.node_insert function in
both the orte_init_stage1 for singleton processes and rds_hostfile.c
rds_base_select.c & rds_base_open.c
- Add and set the global module reference
rds_hostfile.c
- Added functionality to create a new cellid for each hostfile, placing
each entry in the hostfile into the same cellid. Currently this is
commented out with the cellid hard coded to 0, with the intention of
taking this out once ORTE is able to handle multiple cellid's
- Instead of just adding hosts to the Node Segment via a direct call to
the ras_base_node_insert() function. First add the hosts to the Resource
Segment of the GPR using the orte_rds.store_resource() function then use
the API version of orte_ras.node_insert() to store the hosts on the Node
Segment.
- Add 1 new function pointer to module as required by the API.
rds_hostfile_component.c
- Converted this to use the new MCA parameter registration
orte_init_stage1.c
- It is possible that a cellid was not created yet for the current environment.
So I put in some logic to test if the cellid 0 existed. If it does then
continue, otherwise create the cellid so we can properly interact with the
GPR via the RDS.
- For the singleton case we insert some 'dummy' data into the GPR. The RAS
matches this logic, so I took out the duplicate GPR put logic, and
replaced it with a call to the orte_ras.node_insert() function.
- Further before calling orte_ras.node_insert() in the singleton case,
we also call orte_rds.store_resource() to add the singleton node to the
Resource Segment.

a probe to figure out what the remote shell is (NOT CURRENTLY
IMPLEMENTED! you'll get a run-time warning if you set this MCA param
to 0).
- if the remote shell is not csh and not bash, then prefix the remote
command with "( ! [ -e ./.profile ] || . ./.profile;" (and suffix it
with ")") so that we run the .profile on the remote side in order to
set PATHs and the like. See the LAM FAQ for details (will someday
be on the Open MPI FAQ:

frameworks, and components without configure scripts instead of
hard-coded shell variables (for projects and frameworks) and
shell variable building (for components).
* Add 3rd category of component configuration (in addition to configure
scripts and no-configured components): configure.m4 components. These
components can only be built as part of OMPI (like no-configure), but
can provide an m4 file that is run as part of the main configure
script. These macros can set whether the component should be built,
along with just about any other configuration wanted. More care must
be taken compared to configure components, as doing things like setting
variables or calling AC_MSG_ERROR now affects the top-level configure
script (so calling AC_MSG_ERROR if your component can't configure
probably isn't what you want)
* Added support to autogen.sh for the configure.m4-style components,
as well as building up the m4_define lists ompi_mca.m4 now expects
* Updated a number of macros to be more config.cache friendly (both
so that config.cache can be used and so the test can be quickly
run multiple times in the same configrue script):
- ompi_config_asm
- c_weak_symbols
- c_get_alignment
* Added new macros to be shared when configuring components:
- ompi_objc.m4 (this actually provides AC_PROG_OBJC - don't ask...)
- ompi_check_xgrid
- ompi_check_tm
- ompi_check_bproc

- After long discussions and ruminations on how we run components in
LAM/MPI, made the decision that, by default, all components included
in Open MPI will use the version number of their parent project
(i.e., OMPI or ORTE). They are certaint free to use a different
number, but this simplification makes the common cases easy:
- components are only released when the parent project is released
- it is easy (trivial?) to distinguish which version component goes
with with version of the parent project
- removed all autogen/configure code for templating the version .h
file in components
- made all ORTE components use ORTE_*_VERSION for version numbers
- made all OMPI components use OMPI_*_VERSION for version numbers
- removed all VERSION files from components
- configure now displays OPAL, ORTE, and OMPI version numbers
- ditto for ompi_info
- right now, faking it -- OPAL and ORTE and OMPI will always have the
same version number (i.e., they all come from the same top-level
VERSION file). But this paves the way for the Great Configure
Reorganization, where, among other things, each project will have
its own version number.
So all in all, we went from a boatload of version numbers to
[effectively] three. That's pretty good. :-)
