Re: Timeout for connect in Anyevent::HTTP. Help, please.

[Tanktalus]

Just a brief look at AnyEvent::HTTP's fine documentation indicates a timeout key. This timeout value is used (and reset) at various stages of the connection, but may suffice for you.

If not that, then you may need to get a bunch more complex, creating your own timer for on_prepare, keeping the guard object for the overall http_request, and destroying the guard if the timeout happens. I'm not going to provide an example of that only because it's probably more complex than required, so it'd be a waste of time to create it.

About a simple timeout all clear (Documentation: "timeout => $seconds The time-out to use for various stages - each connect attempt will reset the timeout, as will read or write activity, ie this is not an overall timeout." ) But how to set overall timeout, which does not reset?

[Tanktalus]

Without testing anything:

my $w;
my $cv = http_request GET => $url, ..., sub { $w = undef; callback(...
+) }; # kill the watcher when we're done
$w  = AE::timer $timeout, 0, sub { $cv = undef }; # kill the http requ
+est after $timeout seconds

However, that may not work depending on what else you're doing - if you're waiting on $cv->recv, you may want to use $cv->send() if $cv inside the timer callback to trigger that.

Basically, start the request, then start the timer, then wait, and when the http request returns, clear the $cv variable and/or clear $w to terminate the timer. There are a few things to pay attention to here, to clear cv's and watchers at the appropriate time, but it should otherwise be straight forward.
