Decode the new int_string switch type. + (define_makeflags): Add new int_string switch data to MAKEFLAGS. + (job_fds[]) Array to contain the pipe file descriptors. + (main): Parse the job_slots_str option results. If necessary, + create the pipe and seed it with tokens. Set the non-blocking bit + for the read fd. Enable the signal handler for SIGCHLD even if we + have a non-hanging wait; it's needed to interrupt the select() in + job.c:start_waiting_job(). + + * make.h: Declare job_fds[]. + + * job.h (struct child): Add job_token field to store the token for + this job (if any). + + * job.c (reap_children): When a child is fully reaped, release the + token back into the pipe. + (free_child): If the child to be freed still has a token, put it + back. + (new_job): Initialize the job_token member. + (start_waiting_job): For local jobs, if we're using the pipe, get + a token before we check the load, etc. We do this by performing a + non-blocking read in a loop. If the read fails, no token is + available. Do a select on the fd to wait for a token. We need to + re-enable the signal handler for SIGCHLD even if we have a + non-hanging waitpid() or wait3(), so that the signal will + interrupt the select() and we can wake up to reap children. + (child_handler): Re-enable the signal handler. The count is still + kept although it's not needed or used unless you don't have + waitpid() or wait3(). + 1999-04-03 Paul D.
