similar to: Upstart

Hi, I''m deploying Unicorn on a Rails application with RUnit. Technically I''m using Chef''s deployment tools, if any of you are familiar with it (https://github.com/opscode-cookbooks/application_ruby) but to be clear they aren''t doing anything magical, so this is purely an issue with RUnit and Unicorn. The TL;DR of the following post, which has lots of

I cannot find any good example of a unicorn upstart task that works properly for the following: * Upstart will restart if unicorn dies * Can send USR2 signal to unicorn to do a no downtime deploys * Able to stop upstart job, even after a deploy I have tried the following: expect fork respawn setuid www-data chdir /var/www/app/current exec bundle exec unicorn_rails -E production -c

Hi, Unicorn is saying it''s terminating but it''s not actually. Check out the gist:?https://gist.github.com/1104930 Using: - Ruby 1.9.2p180 - unicorn 4.0.1 - kgio 2.6.0 - bundler 1.0.15 - Linux maynard 2.6.38-10-generic #46-Ubuntu SMP Tue Jun 28 15:07:17 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux Please let me know if there''s any other info I can provide. Thanks, Jesse

First off thanks very much for all the hard work on unicorn. Alas, we''ve encountered an issue where unicorn fails to spawn new workers that have loaded the incoming revision on a capistrano deploy. I''m not entirely sure the issue is due to unicorn as it appears that bundler was responsible for a similar issue in the past:

?Hi, I was wondering if anyone has managed to get the preload_app and SIGUSR2 combination working well with upstart? My issue currently is that when I perform a SIGUSR2 against the master, check everything''s working and close off the old master, upstart then attempts to restart it because the original PID/binary are no longer running. What is the correct way of handling this? In my

Hello! Can anyone explain why my Unicorn installation (for RoR site) have so many worker threads? * screenshot: http://i.stack.imgur.com/U9TFR.png * unicorn.rb: https://gist.github.com/907th/4995323 Thanks!

Hi, I''m trying to use unicorn in a test deployment of a Rails app that uses Mongoid, so Activerecord isn''t included in the app. When I start unicorn through Capistrano though, the stderr log fills up endlessly with identical ActiveRecord-related errors: I, [2012-12-05T04:19:25.375952 #5096] INFO -- : Refreshing Gem list I, [2012-12-05T04:19:32.941249 #5096] INFO -- :

hi. i''ve been trying to upgrade my stack to ruby 2.0 but keep getting this on ubuntu (not on my local os x): /hello/shared/bundle/ruby/2.0.0/gems/unicorn-4.6.3/lib/unicorn/http_server.rb:746:in `for_fd'': Bad file descriptor (Errno::EBADF) from /hello/shared/bundle/ruby/2.0.0/gems/unicorn-4.6.3/lib/unicorn/http_server.rb:746:in `block in inherit_listeners!'' from

I am having issues when using unicorn with a Capistrano deployment. >From what I have been able to understand Capistrano uses a scheme in wich every release is deployed inside the releases directory under a unique name and if the transaction was successful, creates a symlink named current that will point to that release. So I end up with a deployment directory such as:

Hi All, as I can see on https://github.com/defunkt/unicorn/blob/master/lib/unicorn.rb#L53 the?Rack::CommonLogger used only in development env and in weird evn called "deployment". Any chance to add "production" to this case? Serg Podtynnyi

hey, i am a big unicorn fan -- i have been running it in production since late 2010, and it is happily handling (literally) billions of backend requests for a popular facebook game. i also <3 unicorns in general ..... so i decided to make an awesome t- shirt, sporting the "Angry Unicorn" that you may remember from github error pages. i hope some of you might like it as well:

Unicorn is an HTTP server for Rack applications designed to only serve fast clients on low-latency, high-bandwidth connections and take advantage of features in Unix/Unix-like kernels. Slow clients should only be served by placing a reverse proxy capable of fully buffering both the the request and response in between Unicorn and slow clients. * http://unicorn.bogomips.org/ * mongrel-unicorn at

I have strange error that happens after couple of hours. Some instances start to respond on any request with status code 500. Log file unicorn.stderr.log gets populated with this error: app error: undefined method `each'' for nil:NilClass (NoMethodError) /usr/local/lib/ruby/gems/1.9.1/gems/rack-1.1.2/lib/rack/utils.rb:267:in `initialize''

Hi, I followed the procedure to replace a running unicorn. Works fine, except for one thing: after I decide to back out, ie I send a HUP to the old master followed by a QUIT to the new master, then: 1. the new master does die, and the old master does work again 2. the "old" master keeps running with a process name of "master (old)" 3. the "old" master keeps

Hi, I am getting failing tests on both OSX and debian squeeze, but the errors are different. On both my machines, it is commit 7c125886b5862bf20711bae22e6697ad46141434 that breaks the tests. I am using an old(ish) version of ruby: 1.9.3p125, but I don''t think that should matter. The error I get when I test 4.7.0 on OSX 10.7.5: : Finished tests in 0.041678s, 263.9282 tests/s,

Hi, We recently made the switch to 1.9 for our large rails 2.3.14 project and ran into some strange behavior from the unicorns where encoding problem would cause blank 500 pages to be "randomly" served to users (we run ~10 x 5 unicorn workers behind our load balancer). We found that unicorn workers were dying when someone requested a url with utf-8 in it, and died in such a way that

Hi, We''ve just migrated one of our rails applications from nginx/passenger running on REE 1.8.7 Ubuntu 8.04 to unicorn running on MRI 1.9.3 on Ubuntu 10.04. The app makes a number of calls to internal services using curb. Our deployment script stops unicorn by sending SIGQUIT to the unicorn master, sleeps for a few seconds to ensure that HAProxy has taken the node out of service and

Hey all, Below is a proposed patch I worked on over the weekend. Just adding a note here to mention that I''m currently not a subscriber to the mailing list, so please CC me on any replies. Let me know what you all think. This change was made on a local topic branch off of the maint branch. If you''d like to view the change on GitHub, you can do so here:

Hello all, I''m wondering if you deploy nginx: 1) on the same machine that runs unicorn (exclusively proxying to that) 2) on a different machine that doesn''t run unicorn 3) both, nginx could forward to either to localhost or another host on the same LAN And of course, the reason(s) you chose what you chose. I''m inclined to believe many folks are on 1) simply

Greetings, I''m getting this - ActiveModel::MissingAttributeError: missing attribute: some_attr - on a random basis under a unicorn server, running rails 3.2 and ruby 1.9.3 As the case of the last poster in the following thread - https://github.com/rails/rails/issues/1906 - I too am able to resolve this issue by settingpreload_app to false. However, this is not the behaviour I want to
