Thu 26 May 2011 12:51:22 PM UTC, comment #3: The problem appears to be caused by (or at least related to) the parser thread getting stuck in the "aborting" state after being killed upon successful authentication. The following patch exposes the issue as a hang on Ruby 1.9.2, but runs normally on 1.8.7 and 1.9.1. module Jabber class Stream def stop @parser_thread.kill @parser_thread.join # <-- Wait for original parser thread to die before continuing @parser = nil end end end	Tim Jensen <tjensen>
Fri 13 May 2011 08:35:48 PM UTC, comment #2: The server is ejabberd version 2.1.2-2, running on Ubuntu 10.04.2 LTS.	Tim Jensen <tjensen>
Fri 13 May 2011 08:19:59 PM UTC, comment #1: The following monkey-patch instrumentation of REXML is sufficient to make the problem disappear: module REXML::Parsers class BaseParser alias_method :the_real_pull, :pull def pull puts "PULL START #{Thread.current}" the_real_pull ensure puts "PULL END: #{Thread.current}" end end end	Tim Jensen <tjensen>
Fri 13 May 2011 08:05:31 PM UTC, original submission: I'm trying to use XMPP4R 0.5 with Ruby 1.9.2-p180 on Windows 7, but I am observing a REXML exception during the authentication step. The error appears to be timing sensitive because it occurs about 90% of the time and monkey patching REXML to produce debug output makes the issue disappear. I have attached a small script to reproduce the error. I have also attached the output from running the script with Ruby 1.9.2-p180 on Windows 7. This issue does not occur with Ruby 1.8.7-p334 on Windows 7. This issue does not occur with Ruby 1.9.2-p180 on Linux. This issue does not occur with Ruby 1.8.7-p334 on Linux.	Anonymous
