in thread Force 2 'ctrl-c's to kill program

Must get my head around what it is doing now.

$SIG{ INT } = sub { ## State makes $last a closure; that is a variable that remember' +s its value ## between invocations of the subroutine state $last = 0; ## if the time now is greater than 2 seconds later than the last +time we saw a ^C if( ( time - $last ) > 2 ) { ## Overwrite the last time with the current time $last = time; ## And just return; ignoring this ^C return; } ## However, if it is less than 2 seconds; die. die 'Interupted by ^C^C'; };

    Ah, that makes a lot of sense. "State" was new to me (not using 5.010 yet) so threw me a little. Cheers

[erix]: "code of someone that died" -- kinda nice if your code stops working too
[erix]: hard to implement, hmm
[Corion]: erix: Well, they also seem to have changed the server, or some software, or whatever, and seem to be in the process of changing the DB schema from having the "username" as primary key to something else.
[Corion]: Far too many things being done at once, or maybe only now has it become apparent that nobody knows that piece of software anymore
[marto]: good morning all
[Corion]: I consider having an abstract key as userid in your system good, because the "real" company-wide (or even larger) user id will likely not fit your criteria well
[Corion]: A good morning marto!
