FreeBSD Port: swatch-3.0.8

[goblin]

Hello joseph,

at first, sorry for my poor english, but i hope
you can understand me :)

i have some problems using this program, and fixed it,
but it is a little boring to patch swatch on each cvsup %(
so i ask you to apply my patch to this port plz
(current patch is for swatch-3.0.8_1)

here are the problems:

1. using sendmail program
here is swatch.conf example
----------------
watchfor /blin/
        echo
        mail addresses=goblin\@nnt.ru
----------------
it sends mail on first occurence of blin, but then it hangs
in wait() state, waiting while sendmail process is finished
(while it is already died)
patch is to add

local $SIG{CHLD} = 'default';
before open(SENDMAIL, "| /usr/sbin/sendmail...")
so wait() returns successfully on sendmail's exit

2.
while using tail cmd, it does not like any signals,
so on kill -HUP <swatch.pl pid>, it sends SIGTERM
to child .swatch.pid process, but
in function goodbye() it hangs on exit(0),
because /usr/bin/tail still works...

patch is to start /usr/bin/tail not like
open (TAIL, "/usr/bin/tail |")

but fork-exec with saving child pid and kill TAIL process in
goodbye

all works fine (kill -1 <swatch pid, .swatch.pid pid>)

3. and, may be, it is useful to start tail with not -n 1,
but -n 0, but it is ... as you wish

Best regards,
