Hello all, Last week, I finally decided to put into motion some ideas I''ve been kicking around for a year in my head since last year... Basically I don''t want to have to deal with threads or support platforms that rely on or encourage threads. Especially given MRI 1.9 where kernel threads are more difficult to debug than green ones. Given the limited scope of this project,

This means we no longer waste an extra file descriptor per worker process in the master. Now there''s no need to set a higher file descriptor limit for systems running >= 1024 workers. --- I just pushed this out to git://bogomips.org/unicorn.git and it''ll be in Unicorn 4.x. The subset of raindrops used by Unicorn should work on all machines with mmap(2) +

Hi, I''m wondering why SIGINT and SIGTERM both were chosen for the quick shutdown? I agree with SIGINT but not with SIGTERM. A lot of unix tools send SIGTERM as default (kill, runit among some) and it seems to be the standard way of telling a process to quit gracefully but not among Ruby people (there are a few other ruby processes behaving the same way). I just think it''s weird

We''re using unicornctl restart with the default before/after hook behavior, which is to reap old Unicorn workers via SIGQUIT after the new one has finished booting. Unfortunately, while the new workers are forking and begin processing requests, we''re still seeing significant spikes in our haproxy request queue. It seems as if after we restart, the unwarmed workers get swamped by

Has anyone seen anything like this before? I can get it to happen all the time if I issue a HEAD request, but it only happens very intermittently on GET requests. I''m using Ruby 1.9.2p180. Any ideas on where to start debugging? 204.93.223.151, 10.195.114.81 - - [11/Aug/2011 21:03:50] "GET / HTTP/1.0" 200 37902 0.5316 app error: Content-Length header was 37902, but should be

Installing from RubyGems.org: gem install --pre unicorn >From db919d18e01f6b2339915cbd057fba9dc040988b Mon Sep 17 00:00:00 2001 From: Eric Wong <normalperson at yhbt.net> Date: Tue, 29 Jan 2013 21:02:55 +0000 Subject: [PATCH] unicorn 4.6.0pre1 - hijacking support This pre-release adds hijacking support for Rack 1.5 users. See Rack documentation for more information about hijacking.

If unicorn doesn''t get terminated cleanly (for example if the machine has its power interrupted) and the pid in the pidfile gets used by another process, the current unicorn code will exit and not start a server. This tiny patch fixes that behaviour. --- lib/unicorn/http_server.rb | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/lib/unicorn/http_server.rb

Hey guys, Started running unicorn in a production server like two weeks ago. It''s been running smoothly, but looking at the logs found 44 exceptions like this: E, [2010-06-02T16:17:15.117071 #22680] ERROR -- : Read error: #<TypeError: can''t modify frozen string> E, [2010-06-02T16:17:15.117270 #22680] ERROR -- :

We''ve been running unicorn-3.6.2 on REE 1.8.7 2011.12 in production for quite some time and we use monit to monitor each unicorn worker. Occasionally, I''ll get a notification that a worker has timed-out and has been re-spawned. In all these cases, when I look at the rails logs, I can see the last request that the worker handled, and they all have appeared to complete

Changes: Rewindable "rack.input" may be disabled via the "rewindable_input false" directive in the configuration file. This will violate Rack::Lint for Rack 1.x applications, but can reduce I/O for applications that do not need a rewindable input. This release updates us to the Kgio 2.x series which should play more nicely with other libraries and applications. There are

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

Hi all, I''ve pushed the following patch out go git://git.bogomips.org/unicorn along with a few other Rails-related test updates. This is more of a shotgun fix (but less code is better :) since I haven''t been able to reproduce the brokeness people have been seeing with "unicorn_rails" and Rails 3 betas. Even though "unicorn" works perfectly well for Rails3,

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, This morning, while checking for a correct deployment, we found out that the Unicorns we are using were sending 500 Internal errors very frequently to the HAProxy that sits in front of them. After some investigation, It turned out that HAProxy checks the backend by opening and closing a connection to the unicorn. Unfortunately the Unicorns we use ( v 0.990.0 ) will try to reply to this probe

Hi, A couple days ago, I was trying to run Unicorn for Ramaze, and found that `Unicorn.run'' didn''t share the same interface with other Rack handlers, i.e. `options[:Host]'' and `options[:Port]'' Because of this, I can''t just use: Rack::Handler.register(''unicorn'', ''Unicorn'') And invoke this:
