- 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.
This program does what the old one did, PLUS:
- Supports parallel jobs (like the SunOS yppush)
- Does everything in one proces instead of fork()ing off
children processes as callback listeners (this is done
using async socket I/O).
- Can be used to transmit maps to user-specified hosts.
- Has a much more verbose verbose option.
- Reuses existing code from ypserv and ypxfr.
- Uses some rpcgen-erated code as well.
- Isn't fattening. :)
Note that this is going in /usr/sbin rather than /usr/bin like
the old one. yppush is an administrative command it it's anything.
