That's just a wrapper around POSIX sigaction(), right? As I
understand it that's equivalent to the old unsafe signals in Perl
before 5.8. I'd rather avoid that if it all possible!
Yes, when you're under 5.8+, it's the POSIX routines.
From the POD:
Unfortunately, at least with perl 5.8.0, the result is that
doing this
effectively reverts to the 'unsafe' signals behavior. It is
not clear
whether this would be the case in perl 5.8.2, since safe flag
can be
used to ask for safe signal handling. I suspect this
separates the the
logic of which "sa_flags" are used install the handler, and
whether
deferred signal is used.
You've got a catch-22: If you ALWAYS want the signal to fire on time,
then you should expect unsafe signals.
Just clean up after yourself.
Personally, when coding DBIx::HA I couldn't find another way.
