Delay setting - of dwProcessId until process is capable of processing signals - since this field is used to build signal semaphores. - * signal.cc (kill_worker): Perform a `proc_exists' on the pid - in question if signal == 0.

The upper 16 bits - are used for special cygwin operations. - * winsup.h: Change definition of do_exit to allow calling from - signal handler. - * dcrt0.cc (do_exit): Change to allow calling from signal handler - in place of _exit. This is necessary to ensure that only cygwin - internal applications can exit with the upper order 16 bits set - to non-zero. - -Wed Nov 12 23:02:34 1997 Geoffrey Noer <noer@cygnus.com> - - patch from cgf@bbc.com (Chris Faylor): - * dcrt0.cc (do_exit): New function. Subsumes functionality of - _exit but takes a DWORD argument. Changed to avoid some shutdown - activities when called with REPARENTING bit set in argument. Also - explicitly kills any executing non-cygwin subprocess from a - spawn(P_OVERLAY)... - (_exit): Use do_exit for exiting. Ensure that only low order 1 - bits of status are used or confusion will result if exiting with - some higher order bits set. - * exceptions.cc (set_process_mask): Reflect new method for - sig_send to send signals to self. - (handle_sigsuspend): Reflect new method for sig_send to send - signals to self. - * fork.cc: A handle name was changed in the pinfo structure to - be more reflective of its use. Change forkee_stopped to - subproc_ready everywhere. - * pinfo.cc (pinfo::clearout): Change forkee_stopped to - subproc_ready. - (pinfo_init): Use PID_EXECED flag to determine if this process has - been execed. If so, signal the remaining stub in the process - which invoked us so that the stub can terminate and let us take - over as this pid. - * sigproc.cc (sig_send): Change method for determining if sending - signals to myself. A NULL pointer means communicate with my - signal handler. This is necessary to allow communication with - our own signal processors after reparenting an execed process. - Also, add an additional test to detect if a process goes away in - the middle of attempting to send it a signal. - (allow_sig_dispatch): Reflect new method for sig_send to send - signals to self. - (getsem): Use dwProcessId in names for signal semaphores. Allows - communicating with both parts of a process that is temporarily - "split in two" while execing. - (sig_proc): Avoid printing an error if WAIT_FAILED and exiting - anyway. Process requests even if loop_wait == 0. - (proc_subproc): Defensive check for manipulating processes prior - to initialization or after terminating sigproc. - Use different check for subprocesses that have been reparented. - Hopefully this will eliminate WFSO, error 6 problems. - (wait_subproc): Only exit when loop_wait == 0 and not dealing with - a process. - * spawn.cc: Set up two global variables, used on exit when - execing a non-cygwin process: hExeced - handle of non-cygwin - process which is being waited for by a stub, pExeced - windows pid - of the process. - (spawn_guts): Reorganize to always (temporarily) wait for the new - process when P_OVERLAY. If a cygwin process is invoked, then the - wait will return when an event is signalled and the new process - will be "reparented" in the ppid. If a non-cygwin process is - invoked, wait until the process exits or a signal is received - which terminates the process. In this case, the do_exit function - will terminate the non-cygwin process. - * winsup.h: Rename forkee_stopped to subproc_ready since this - event now has a dual role which is better defined by this new - name. Add a new flag (PID_EXECED) for process_state.
