This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
- Remove unused 'pid' member from the jobs structure. (This was left over
from an earlier incarnation of the program that used multiple processes.)
- Remove #ifdef'ed longjmp() stuff.
- Print warning message if the 'pushing' host is not the master for
a map being pushed but don't bail out. (While yppush should only
be used on an NIS master, using it elsewhere is not an unpardonable sin.)
yppush.8:
- Fix a couple of mind-os.
Makefile
- Change format to hopefully ease bootstrapping. (Suggested by wollman.)
Other Makefiles should follow.
- Don't do longjmp()s from inside a signal handler. Even though I got
things to work the way I wanted, it's bad karma.
- Remember to clear the sa_mask with sigemptyset() before masking signals
when using sigaction() to set up the SIGIO handler.
- Break out of the wait loop in yppush_exit() when the five minute
timeout expires instead of looping around for another pass. If ypxfr
on the other end fails somehow and never sends a response, we don't
want to wait around forever.
