30 | |
31 | This module collection manages coroutines. Coroutines are similar to |

32 | threads but don't (in general) run in parallel at the same time even |
32 | manpage. This manpage mainly contains reference information. |
33 | on SMP machines. The specific flavor of coroutine used in this module |
|
|
34 | also guarantees you that it will not switch between coroutines unless |
|
|
35 | necessary, at easily-identified points in your program, so locking and |
|
|
36 | parallel access are rarely an issue, making coroutine programming much |
|
|
37 | safer and easier than threads programming. |
|
|
38 | |
33 | |
39 | Unlike a normal perl program, however, coroutines allow you to have |
34 | This module collection manages continuations in general, most often |
40 | multiple running interpreters that share data, which is especially useful |
35 | in the form of cooperative threads (also called coroutines in the |
41 | to code pseudo-parallel processes and for event-based programming, such as |
36 | documentation). They are similar to kernel threads but don't (in general) |
42 | multiple HTTP-GET requests running concurrently. See L<Coro::AnyEvent> to |
37 | run in parallel at the same time even on SMP machines. The specific flavor |
43 | learn more. |
38 | of thread offered by this module also guarantees you that it will not |
|
|
39 | switch between threads unless necessary, at easily-identified points in |
|
|
40 | your program, so locking and parallel access are rarely an issue, making |
|
|
41 | thread programming much safer and easier than using other thread models. |
44 | |
42 | |
45 | Coroutines are also useful because Perl has no support for threads (the so |
43 | Unlike the so-called "Perl threads" (which are not actually real threads |
46 | called "threads" that perl offers are nothing more than the (bad) process |
44 | but only the windows process emulation ported to unix), Coro provides a |
47 | emulation coming from the Windows platform: On standard operating systems |
45 | full shared address space, which makes communication between threads |
48 | they serve no purpose whatsoever, except by making your programs slow and |
46 | very easy. And threads are fast, too: disabling the Windows process |
49 | making them use a lot of memory. Best disable them when building perl, or |
47 | emulation code in your perl and using Coro can easily result in a two to |
50 | aks your software vendor/distributor to do it for you). |
48 | four times speed increase for your programs. |
51 | |
49 | |
|
|
50 | Coro achieves that by supporting multiple running interpreters that share |
|
|
51 | data, which is especially useful to code pseudo-parallel processes and |
|
|
52 | for event-based programming, such as multiple HTTP-GET requests running |
|
|
53 | concurrently. See L<Coro::AnyEvent> to learn more on how to integrate Coro |
|
|
54 | into an event-based environment. |
