Easy Daemons...

[chorg]

Anyone have experience with any of the Daemonizing modules? Like Proc::Daemon or Proc::Application? What I need to do is have my perl code running so I can just fire data to be processed at it, without paying the start-up penalty. It would be cool to have all the server trimmings too , like command line args etc...

I've yet to use Proc::Daemon myself, but Search and Super Search on 'daemonize', 'background', and 'fork' turned up the following potentially relevant threads:
• Proc::Daemon
• How do I run a script in the background? How should I run a script as daemon?
• perl daemon
• Is it possible to background a perl script from within itself?
• Background Process
• How do run a subroutine in the background
• How do I fork a daemon process?

Update: and for you Win32 fans out there, try this on for size:   How to hide window with Win32:API?

I read all that stuff, and I'll implement it if I have to, but I always try to avoid re-inventing the wheel. Also, I wanted to see if there were undocumented problems, like the old memory leak problem in Tie::Cache::LRU

ybiC has you covered, and i recommend Proc::Daemon, but if you really want to get a full understanding on daemons and servers (forking, pre-forking, pre-threaded, etc.) then get thee a copy of Network Programming with Perl. You will not regret it. ;)

Yes. The key here is that what I want to do is not write my own daemon code. That is fairly tangential to what I have to do. I just need to pop off a quick little "sumthin sumthin" . If I really need to, I will write a daemon app POSIX style, but my focus is more on what the daemon should do, not how to make it. Thus I just want to knock off a generic module. I've settled on Net::Daemon as the weapon of choice for me today. I'll definitely read the book tho - thanks...
