Is the signal handler supposed to work like this?by dpmott (Scribe) |

dpmott has asked for the wisdom of the Perl Monks concerning the following question: The short question is this: should spawning a thread change how signal handlers behave? See below for a working code snippet. So, I was banging my head against the keyboard trying to remember how to read in a series of lines from STDIN with Win32 ActivePerl. After much googling, I realize that I've only ever gotten characters with Term::ReadKey, and that isn't even close to what I wanted. Apparently, nothing is. All I wanted to do was this, and be able to type ctrl-D to signify that I was done: (Somebody let me know if I missed the obvious boat here; I couldn't find the way to do this.) So, I decided to go with ctrl-C: Hmmm... that doesn't work either. It kills my script. I soon came to realize that I'm using that nifty new Perl v5.8.8 with "safe" signals, and I suspect that this was getting in the way. Sadly, Perl::Unsafe::Signals isn't available via ppm for ActivePerl, so I didn't get to find out either way. What I did discover, quite by accident was that spawning a thread changes the behavior of the signal handler: So, I'm left wondering if that was supposed to work that way?
