744ed49b2d Begin cleanup of the thread_lock calls in ORTE. We'll ignore the ones in the rml/oob for now as that code block is being rewritten anyway.

fd28b392bf - An intrusive commit yet again (sorry): with the separation we
get bitten by header depending on having already included
   the corresponding [opal|orte|ompi]_config.h header.
   When separating, things like [OPAL|ORTE|OMPI]_DECLSPEC
   are missed.

   Script to add the corresponding header in front of all following
   (taking care of possible #ifdef HAVE_...)

 - Including some minor cleanups to
   - ompi/group/group.h -- include _after_ #ifndef OMPI_GROUP_H
   - ompi/mca/btl/btl.h -- nclude _after_ #ifndef MCA_BTL_H
   - ompi/mca/crcp/bkmrk/crcp_bkmrk_btl.c -- still no need for
     orte/util/output.h
   - ompi/mca/pml/dr/pml_dr_recvreq.c -- no need for mpool.h
   - ompi/mca/btl/btl.h -- reorder to fit
   - ompi/mca/bml/bml.h -- reorder to fit
   - ompi/runtime/ompi_mpi_finalize.c -- reorder to fit
   - ompi/request/request.h -- additionally need ompi/constants.h

 - Tested on linux/x86-64

728a24c8ec After considerable patience and help with debugging/testing from Tim M and Jeff S, return a completed and pretty well tested patch of the IOF to the trunk. This commit includes the previously reverted r20074, r20068, and r20064, as well as changes to fix those commits.
Basically, the remaining problem turned out to be:

1. closing stdout/stderr during orte_finalize of mpirun

2. inadvertently setting up a write event on fd = -1

3. devising a scheme to more accurately track when the stdin write event was active vs closed so it only got released once

This passed prelim MTT testing by Jeff and Tim, but should soak for awhile before migrating to 1.3.

This commit was SVN r20106.

a07660aea8 Bring over the IOF completion changes. This commit fixes the long-occurring problem whereby application procs could, under some circumstances, lose their final prints to stdout/err. The commit includes:
1. coordination of job completion notification to include a requirement for both waitpid detection AND notification that all iof pipes have been closed by the app

2. change of all IOF read and write events to be non-persistent so they can properly be shutdown and restarted only when required

3. addition of a delay (currently set to 10ms) before restarting the stdin read event. This was required to ensure that the stdout, stderr, and stddiag read events had an opportunity to be serviced in scenarios where large files are attached to stdin.

This commit was SVN r20064.

586334d1c8 Per discussion with Tim Mattox, reset the trunk to pre-19991 level for the iof only. I will shortly add a changeset that will repair the one known error where we were incorrectly closing the stdout/err/diag file descriptors when all we wanted to do was close stdin. I will leave out the changes associated with coordinating proc termination due to race conditions IU encounted during MTT testing. I have been unable to replicate those so far, but we hope to resolve it in the near future.

555bbf0c02 Fix the iof race conditions wrt proc termination. This is comprised of two sections:
1. modify the iof to track when a proc actually closes all of its open iof output pipes. When this occurs, notify the odls that the proc's iof is complete. This is done via a zero-time event so that we can step out of the read event before processing the notification.

2. in the odls, modify the waitpid callback so it only flags that it was called. Add a function to receive the iof-complete notification, and a function that checks for both iof complete and waitpid callback before declaring a proc fully terminated. This ensures that we read and deliver -all- of the IO prior to declaring the job complete.

Also modified the odls call to orte_iof.close (and the component's implementation) so it only closes stdin, leaving the other io channels alone. This fixes the other half of the known problem.

This should fix the ticket on this subject, but I'll wait to close it pending further testing in the trunk.

6e5d844c36 Roll in the revamped IOF subsystem. Per the devel mailing list email, this is a complete rewrite of the iof framework designed to simplify the code for maintainability, and to support features we had planned to do, but were too difficult to implement in the old code. Specifically, the new code:
1. completely and cleanly separates responsibilities between the HNP, orted, and tool components.

2. removes all wireup messaging during launch and shutdown.

3. maintains flow control for stdin to avoid large-scale consumption of memory by orteds when large input files are forwarded. This is done using an xon/xoff protocol.

4. enables specification of stdin recipients on the mpirun cmd line. Allowed options include rank, "all", or "none". Default is rank 0.

5. creates a new MPI_Info key "ompi_stdin_target" that supports the above options for child jobs. Default is "none".

6. adds a new tool "orte-iof" that can connect to a running mpirun and display the output. Cmd line options allow selection of any combination of stdout, stderr, and stddiag. Default is stdout.

7. adds a new mpirun and orte-iof cmd line option "tag-output" that will tag each line of output with process name and stream ident. For example, "[1,0]<stdout>this is output"

This is not intended for the 1.3 release as it is a major change requiring considerable soak time.
