What are the best method to wrap perl code in timeout sections?
What I'm currently using is:
{
local $SIG{ALRM} = sub { die "alarm timeout" };
alarm $timeout;
# Here goes the code that can hang,
#for example network connections
die $@ if $@ && $@ !~ /alarm timeout/;
}
Unfortunatelly this doesn't work that well, especially if you're trying to be generic and you've got no control over the block to protect - this block affects the code inside, for example sleep start behaving erradically, if the code inside rewrites DIE subroutine you can also get in trobule..etc.
I started using Event module, which defines it's own method for timeing out, (they put it in Event::Stats, which is like the first place I would look for it...), but the module is written in C and so is it's timeout ...AFAIK.
