Perl 5.6 introduced something called interpreter threads. Interpreter
|
|
threads are different from 5005threads (the thread model of Perl 5.005)
|
|
by creating a new Perl interpreter per thread, and not sharing any
|
|
data or state between threads by default.
|
|
|
|
Prior to Perl 5.8, this has only been available to people embedding
|
|
Perl, and for emulating fork() on Windows.
|
|
|
|
The threads API is loosely based on the old Thread.pm API. It is very
|
|
important to note that variables are not shared between threads, all
|
|
variables are by default thread local. To use shared variables one
|
|
must use threads::shared.
|
|
|
|
It is also important to note that you must enable threads by doing use
|
|
threads as early as possible in the script itself, and that it is not
|
|
possible to enable threading inside an eval "", do, require, or use.
|
|
In particular, if you are intending to share variables with
|
|
threads::shared, you must use threads before you use threads::shared.
|
|
(threads will emit a warning if you do it the other way around.)
