Hey guys, I''m sending USR2 to unicorn after cap deploy, and the old master is getting replaced by a new master that doesn''t work. Here are some similar threads I found ... http://rubyforge.org/pipermail/mongrel-unicorn/2010-October/000733.html http://rubyforge.org/pipermail/mongrel-unicorn/2010-October/000717.html I''m not using Bundler, and I have working_directory

?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

I am using nginx with unicorn as a reverse proxy. Has been fantastic, but needed to look through some code for first time. Using ruby 1.9.3p194 with rails 3.2.9, development mode with ssl enabled, I start unicorn with -d ...and it does not get served up by nginx. Any ideas, or more information needed? Thanks! Jet Below is my unicorn.rb for developent: # config/unicorn.rb env =

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''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

Hi, I''m currently giving Nginx + Unicorn a try, to eventually replace Apache + Passenger. So far so good. I have a Rails 3.2.5 app behind Unicorn, itself behind Nginx. In this Rails app, I have set page caching for some resources. They are created in Rails.root/public/ to be directly available to Nginx. When I first hit such a page, the static cache file is not present, so the Rails

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, For one of our apps we switched to unicorn from mongrel. The unicorn server use to run behind an apache with timeout of 300sec, as sometime the customer may do a large file upload. After we made the switch we started getting lots of Unicorn::ClientShutdown occurred in photos#flash_upload bytes_read=2762663 (pr some other number) We were not able to recreate it in our tests, but support was

I''ve setup nginx with this server { listen 80; server_name unicorn.local; location / { proxy_pass http://unicorn; } } upstream unicorn { server unix:/Users/mattmongeau/projects/test/unicorn/tmp/sockets/unicorn.sock; } When I run unicorn_rails -c config/unicorn.rb -E development I can access the application just fine on unicorn.local When I run unicorn_rails -c

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

Hey everyone, Working on an engine for rails that needs specialized behavior with forking and I had a couple questions. 1. What is the best way to determine whether the app is indeed running inside a unicorn server? Most of the attempts I can find to detect check to see if the main modules for Unicorn are defined, but this really only checks to see that Unicorn is present, not that you are

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

Hi, I have a question about automating the restarting of Unicorn with the following steps, and much appreciate your help. Assumption: (i) "pid" is set to unicorn.pid in the config file; (ii) a Unicorn process is already running. (1) kill -USR2 `cat unicorn.pid` (via Capistrano deployment task for example) (2) Inside the "before_exec" hook in the config file, do: kill -QUIT

Streaming works with Unicorn + Apache. Both with and without deflating. My understanding is that Unicorn + Apache is not a good combination though because Apache does not buffer, and thus Unicorn has no fast client in front. (I don''t know which is the ultimate technical reason Unicorn puts such an emphasis on fast clients, but will do some research about it.) I have seen in

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,

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:
