I am doing work in a thread that calls log4r. At the end of the thread call, I call Thread.current().exit() as I want to make sure that the thread dies. However, this call seems to deadlock with log4r. Is there a bug in log4r or is there some call I should make before called .exit()? Thanks. I am using: log4r (1.1.7) ruby 1.8.7 (2009-06-12 patchlevel 174) [x86_64-linux] gem 1.3.5 Trace: *** glibc detected *** ruby: double free or corruption (fasttop): 0x00000000008faf60 *** =======

Add A Comment:
Date: 2010-10-20 23:54 Sender: Seth Goings Sorry - didn't see your comment about the thread locking fix being initially tested. I pulled the repo, installed it, and all is well. What's the life status of this project?
Date: 2010-10-20 23:32 Sender: Seth Goings I ran into this issue with 1.1.8 and Ruby 1.9.1-p378 as well - but using log inheritance. Here's the error I got: <internal:prelude>:6:in `lock': deadlock; recursive locking (ThreadError) from <internal:prelude>:6:in `synchronize' from <internal:prelude>:20:in `exclusive' from C:/Ruby191/lib/ruby/gems/1.9.1/gems/log4r-1.1.8/lib/ log4r/repository.rb:34:in `[]' from C:/Ruby191/lib/ruby/gems/1.9.1/gems/log4r-1.1.8/lib/ log4r/repository.rb:75:in `block in find_ancestor' from <internal:prelude>:21:in `block in exclusive' from <internal:prelude>:8:in `synchronize' from <internal:prelude>:20:in `exclusive' from C:/Ruby191/lib/ruby/gems/1.9.1/gems/log4r-1.1.8/lib/ log4r/repository.rb:73:in `find_ancestor' from C:/Ruby191/lib/ruby/gems/1.9.1/gems/log4r-1.1.8/lib/ log4r/logger.rb:62:in `deal_with_inheritance' from C:/Ruby191/lib/ruby/gems/1.9.1/gems/log4r-1.1.8/lib/ log4r/logger.rb:36:in `initialize' from C:/Documents and Settings/Administrator/My Documents/NetBeansProjects/Log4rtest/lib/main.rb:6:in `new' from C:/Documents and Settings/Administrator/My Documents/NetBeansProjects/Log4rtest/lib/main.rb:6:in `<main>' Here's my testcase: ----------------------- require 'log4r' include Log4r parent_log = Logger.new("Main") parent_log.add(FileOutputter.new(parent_log, :filename => "Main.log", :trunc => true)) log = Logger.new("Main::Child") log.add(FileOutputter.new(log, :filename => "Child.log", :trunc => true)) log.info("Got to this point.") ------------------ I see that the log4r code on GitHub has a possible fix for this, but I wasn't sure if it was a good one. Please tell me if it's a good idea to pull 1.1.9 alpha, since RubyForge (and therefore gem installs) only has 1.1.8 at the current time. A gem, of course, would be much appreciated, since at current time this is a pretty serious issue. :-)
Date: 2010-06-08 07:55 Sender: Yann Golanski Yes, of course. I will clone the repository and try it.
Date: 2010-06-08 05:47 Sender: Colby Gutierrez-Kraybill I've switched log4r to use Monitor instead of Mutex directly. Initial testing seems to be good so far. If you're still available for helping test the changes out, that would be grand. I've pushed the changes into the current head of the git tree for log4r. You can get it either from rubyforge or github, depending on what you prefer: git://rubyforge.org/log4r.git or git://github.com/colbygk/log4r.git Thanks - Colby
Date: 2010-04-13 10:01 Sender: Yann Golanski If you wanted me to help test it, let me know. I am happy to do so.
Date: 2010-04-12 21:31 Sender: Colby Gutierrez-Kraybill This makes sense to me. It may be that section of code pre-dates the Monitor class. The next release is planned to flesh out testing and re-organize the layout of the source tree (moving src/**/* into lib). The usage of mutex directly is dropped in favor of a Monitor mixin, I'd like the test the living crap out of it before release.
Date: 2010-04-08 14:12 Sender: Yann Golanski Another crash... Trace below. I had a look at the source and you use the Mutex class which is not re-entering, as opposed to Monitor which is. I wonder if that maybe the problem? I shall hack the source and see if I can get this bug to re-appear -- which sadly is none trivial. deadlock 0x7fa37bcf57a8: sleep:- - /home/sentinel/.gem/ruby/1.8/gems/log4r-1.1.7/src/log4r/outputter /outputter.rb:128 deadlock 0x7fa37bcf95d8: sleep:- -

Date: 2010-04-01 07:52 Sender: Yann Golanski Thanks. The code that does this is convoluted and has many threads. I suspect it maybe something with threads which is causing side effect problems. Tracking it down for a test while nice is rather hard. I am using RollingFileOutputter. However, most of the code running log4r is really trivial and I can paste it here. I start the logger with: config = { "filename" => "#{File.dirname(__FILE__)}/../log/NetworkSystemMonitor.log&q uot;, "maxtime" => 86400, "trunc" => false, :formatter => Log4r::PatternFormatter.new(:pattern => "%d [%7.7l %C] - %m") } logger = Log4r::Logger.new('mainLogger') logger.outputters = Log4r::RollingFileOutputter.new("mainLogger", config) logger.level = Log4r::INFO Once that is done, each of my class has a logger created by: @logger = Log4r::Logger.new "mainLogger::CheckerMinion <#{Process.pid}>" To be fair, the Process.pdf is just that one class as there are many many of them. The minions do a check (like ping a host) then die. All the other calls are based on @logger(info|error|fatal|...) and thus I suspect pretty well tested. The only other instance is a flush called as such: @logger.outputters.each {|i| i.flush()} before the minion thread calls Thread.current().exit() Does that help?
Date: 2010-04-01 03:43 Sender: Colby Gutierrez-Kraybill Which actual outputter are you using? outputter.rb is the 'abstract' class, from which all implementations of outputters are derived. Looking at the traces above, it looks like you're calling outputter directly instead of a specific outputter implementation such as syslogoutputter or consoleoutputters, etc.. If you could, please include a refined test case that reproduces the bug. If you don't wish to post it to rubyforge, you could email it to me directly.
