Re^2: Threads From Hell #1: How To Share A Hash

[karlgoethebier]

"...whatever it was, it wasn't doing anything useful."

Well, i would say it depends.

It was for learning purposes, a kind of finger exercise.

I didn't mention that i don't have any experience using threads in Perl. My first approach.

I always felt like i'll miss something if i don't go over that next bridge.

My little effort was also inspired by my last thread about P::FM, because that stuff doesn't work on windows. I am sorry that i can't show the error messages, because i don't have a windows box with Perl installed at my disposal tonight.

Also pure curiosity played a role. I have a basic understanding how a counting semaphore works but this stuff is still a kind of magic for me.

And the code i figured out looks very similar to my forking example and doesn't perform so bad.

That's why i couldn't resist.

My very best regards, Karl

So... you were trying to restrict the number of concurrent threads to 4? Yes. It works for that purpose.

(I originally thought is was some attempt to prevent concurrent access to the shared hash; ie. a substitute for lock. My mistake.)
