Net::Server - how to hook post_accept

Heya
I'm using Net::Server with the PreFork personality - and I'm trying to
hook post_accept. I would like have my proc called each time there is a
new connection.

What is the way to do this? The documentation doesn't provide it - and
I can't seem to find the answer online..

I tried to do a

sub post_accept {
<>
}

but it seems to break the flow - and lock up the connection.. nothing
else gets handled (process_request never gets called, etc.) if I define
this sub. If I don't include the post_accept proc, my process_request
gets called just fine... How come I can hook process_request without
breaking the flow, but not post_accept?

How do I get the callback/hook whenever a new connection appears?

thanks!
Jon

Define a sub post_accept_hook, rather than overriding post_accept in your
subclass.

http://search.cpan.org/~rhandom/Net-Server-0.94/lib/Net/Serv er.pm
"
$self->post_accept_hook()

This hook occurs after a client has connected to the server. At this point
STDIN and STDOUT are mapped to the client socket. This hook occurs before the
processing of the request.

For some reason - if i define post_accept_hook - it never gets called!
i just tried it again - and i can't seem to get that thing called.

How come the docs define

sub process_request {
}

and not process_request_hook?

there seems to be an inconsistency?
sub process_request { } works great - and its the same type of hook!

They're not really the same type of hook. The *_hook subs are for doing
additional stuff after the server personality has handled that part of the
request cycle.

process_request is where you plug in your user code to do something useful
once the server has handled all the network stuff - so there isn't a
process_request_hook.

There does seem to be a call to $self->post_accept_hook in
run_client_connection in Net::Server, although I remember seeing a problem in
at least one version of Net::Server where one of the documented hook subs
wasn't called.

Re: Net::Server - how to hook post_accept

Ah - I got it.

works now. I guess i was just confused as to when to add the _hook to
the end of the sub.
