( [id://3333]=superdoc: print w/replies, xml ) Need Help??

Fellow monks,

I am trying to implement a HTTP-Request (GET) to an unreliable server. The problem is that the server will occasionally deadlock and the request will never succeed. That is the programm runs forever.

Update

To clarify the problem: connect is succesfull (200 OK). But while retrieving the content of the response, the server stucks. Then the connection hangs forever.

I just want to skip the blocking page, that is terminate that request on my side, and do the next request or stop the programm.

DNS is working fine.

Setting a timeout ( $ua->timeout() ) or an alarm doesn't work.

I am aware of Get Timout with LWP which adresses the same problem.

There's a similar thread at StackOverFlow: True timeout on LWP::UserAgent request method which suggests using SigAction.

Is there a convenient way to put LWP::UserAgent or WWW::Mechanize in nonblocking mode (like IO::Socket::INET )?

Update

As of perrin's reply:

I've tested it on a W2003 Server with Activstate Perl 5.8.8 and 5.10.0.1004 and on Linux 2.6.24-19-generic with Perl 5.8.8 and 5.10.

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
