1. Writing web application
on Perl6
(In progress)

2. MoarVM’s IO has an
issue.
https://github.com/MoarVM/MoarVM/issues/165

3. Can’t pass fd between
threads

4. orz

5. But we can call libc
methods via NativeCall

6. First, call fork(2) via
NativeCall

7. sub fork()
returns Int
is native
{ ... }

8. Easy.

9. 2nd, call waitpid(2)
via NativeCall

10. module private {
our sub waitpid(Int $pid, CArray[int]
$status, Int $options)
returns Int is native { ... }
}
sub waitpid(Int $pid, Int $options) is export {
my $status = CArray[int].new;
$status[0] = 0;
my $ret_pid = private::waitpid($pid, $status,
$options);
return ($ret_pid, $status[0]);
}

11. Easy!(Patches welcome…)

12. Then,

13. Let’s implement BSD
sockets wrapper.

14. I don’t recommend to
use NativeCall directly.

15. There’s too many C types/
structs.
Too many wrapper types…

16. Write dll in C.
And call it via NativeCall.

17. Raw::Socket
BSD socket wrapper for Perl6

18. Then, write httpd.

19. Support features
• parse request
• send response
• pre-fork
• shotgun - reload code
• Win32 support ← NEW!
