Public bug reported: When using LWP::UserAgent on SSL connections with keep-alive enabled the connection will hang or terminate with an error. This bug was introduced between 10.04 and 12.04.
The attached program ssl-keep-alive.pl run on 12.04 demonstrates the problem. An example run with keep-alive disabled produces the following output (where the first argument is the URL and the second is 0 to disable keep-alive or 1 to enable it): $ ./ssl-keep-alive.pl https://bugs.launchpad.net/ubuntu/+source/libnet-http-perl/+bug/1057609 0 starting GET ... done (elapsed time so far: 2 seconds) starting GET ... done (elapsed time so far: 4 seconds) starting GET ... done (elapsed time so far: 5 seconds) starting GET ... done (elapsed time so far: 6 seconds) starting GET ... done (elapsed time so far: 8 seconds) $ Enabling keep-alive produces differing output: $ ./ssl-keep-alive.pl https://bugs.launchpad.net/ubuntu/+source/libnet-http-perl/+bug/1057609 1 starting GET ... done (elapsed time so far: 2 seconds) starting GET ... done (elapsed time so far: 2 seconds) starting GET ... done (elapsed time so far: 3 seconds) starting GET ... done (elapsed time so far: 3 seconds) starting GET ... done (elapsed time so far: 3 seconds) $ ./ssl-keep-alive.pl https://bugs.launchpad.net/ubuntu/+source/libnet-http-perl/+bug/1057609 1 starting GET ... done (elapsed time so far: 17 seconds) starting GET ... 500 Server closed connection without sending any data back $ Using the latest Net::HTTP::Method module (version 6.06) fixes the problem. See https://rt.cpan.org/Public/Bug/Display.html?id=81237 for details of this bug. Upgrading package libnet-http-perl to the latest upstream version 6.06 not only will fix this problem but also address bug 1057609 (https://bugs.launchpad.net/ubuntu/+source/libnet-http- perl/+bug/1057609). ** Affects: libnet-http-perl (Ubuntu) Importance: Undecided Status: New ** Attachment added: "ssl-keep-alive.pl" https://bugs.launchpad.net/bugs/1161640/+attachment/3604833/+files/ssl-keep-alive.pl -- You received this bug notification because you are a member of Debian Perl Group, which is subscribed to libnet-http-perl in Ubuntu. https://bugs.launchpad.net/bugs/1161640 Title: LWP::UserAgent hangs on SSL connections with keep-alive enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libnet-http-perl/+bug/1161640/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~pkg-perl-maintainers Post to : [email protected] Unsubscribe : https://launchpad.net/~pkg-perl-maintainers More help : https://help.launchpad.net/ListHelp
