fixed launch_task_response msg
added slurm_protocol and slurmd errnos to slurm_errno.h
added print_slurm_addr to src/common/slurm_protocol_api.c
added print_slurm_credential to src/common/slurm_protocol_util.c
cleaned up debug printing and error reporting for src/slurmd/shmem_struct.c
more cleanup
etc

added a few comments and slurm_protocol_errno entries.
More little code cleanup

function now handles recv_len ==0 case and returns a error
recv is sending EOF with the 0 return code because the other side has closed the socket

moved a few more signal calls to posix standard sigaction

added EINTR handling to send and recv protocol routines
improved signal management during sends

must fork before dup in task initiation, cleaned it up and made it more straight forward.
test case runs, std in/out/err still need some work but they do connect back to a perl srun_emu.pl script

signal restoration now occurs in socket_impl

These are transport layer specific routines and thus are defined in the api.h
and implemented in the socket, mongo implementations classes

Added signal call to restore sigpipe after send call

Fixed some code for zero size memory allocates, and zero size messages.

from overwritting previously receieved information

I am implementing the new comm layer in all the api functions
added sockopt parameter SO_REUSEADDR to eliminate socket turn around time during debug.

slurm_protocol_errno.h provides a default place for slurm specific error definitions until Jim completes his general errno implementation

Cleaned up comm layer , this never ends :)
added pack and unpack routines for new communcations paradigm

FD_ISSET now returns an int

lots of cleanup

Added a few extra helper funtions

Added support for looping on datagram receives until all the data that is expect on the encapsulated stream has arrived.
This should have been in the original implementation.

inclusion of autoconf socket #ifdefs

added pad to slurm_addr type char pad[16 - sizeof ( int16_t ) - sizeof (uint16_t) - sizeof (uint32_t) ] ;
explictly defined IPPROTO_XXX in socket() call

changed sizeof ( slurm_address ) to sizeof ( slurm_addr ) the size of the data type, not the size of the pointer pointing to the datatype

how about using log4c

fixed added set_slurm_addres_hton to slurm_protocol_util.c

slurm_protocol_api.c			contains the programers interface.
slurm_protocol_interface.h 		defines the lower layer interface.
slurm_protocol_pack.c			packs messages.
slurm_protocol_util.c			contains utility functions used by the protocol
