...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 have. Any inputs on that, or data I can provide around this issue? Best Regards, Avner Cohen

?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 corre...

...n sorting out the issue would be greatly appreciated. We are following EngineYard''s instructions for loading unicorn via bundle exec: http://docs.engineyard.com/appcloud/howtos/cutomization/customize-unicorn So far we''ve tried deploying with the unicorn config set to both "preload_app true" and "preload_app false". (unicorn.rb being used: https://gist.github.com/9a208e3d1d1e44161018) When "preload_app true" is used the "uninitialized constant Prefix::OurCustomApi (NameError)" log entry/stacktrace appears once. And the workers never load the in...

Unicorn users: The pread(2)/pwrite(2) syscalls are very useful for making libraries like this one (that rely on an on-disk database) compatible with preload_app. TokyoCabinet is a great example of a library that''s already compatible with Unicorn+preload_app out-of-the-box. ----- Forwarded message from Eric Wong <normalperson at yhbt.net> ----- From: Eric Wong <normalperson at yhbt.net> To: Clifford Heath <clifford.heath at gmai...

Hi all, I''m fighting with the after_fork hook and my sinatra application.

We now give an example of how a before_fork hook can be used to incrementally migrate off the old code base without hitting a thundering herd (especially in the "preload_app false") case. Also comment on the per-worker listen usage in the RDoc, not just a hidden comment. --- I just pushed this out earlier, this example was inspired by Chris Wanstrath''s before_fork hook but modified to use SIGTTOU instead of SIGQUIT for all but the last worker to mini...

Hi all, I''m having issues with Unicorn and connecting to RabbitMQ using the tmm1-amqp gem. I''ve tried lots of approaches. The classic initializer with Thread.new { EM.run } for the Rails app and even tried using the Qusion library. (https://github.com/danielsdeleo/qusion) I''ve made a simple mod to Qusion for it to monkey patch unicorn too. The code looks

...port, the errors are rendered as normal with a 500 page, the same port, throught nginx, shows errors like you do in development. The app is rails latest (not 3), i run it with unicorn_rails -E production -c /root/pbr/current/config/unicorn.rb -D and unicorn.rb looks like.. worker_processes (20) preload_app(true) Im thinking it could be a permissions problem, the rails directory is in under root, nginx runs as user nginx, but i have given chown permission the the directory?

...n) for rb_thread_call_without_gvl (and similar) functions extensions. Most notably, this fixes compatibility with newer versions of the ''pg'' gem which will cancel a running DB query if signaled[1]. This also has the nice side-effect of allowing a premature master death (assuming preload_app didn''t cause the master to spawn off rogue child daemons). Note: users should also refrain from using "killall" if using the ''pg'' gem or something like it. Unfortunately, this increases FD usage in the master as the writable end of the pipe is preserved in the...

If I''m running two rails apps on the same server using Unicorn, I have to run two instances of Unicorn, right? If so, then here''s a place where passenger might win in terms of memory use, as the rails code will be loaded into memory twice, right? I''m still probably going with Unicorn, but just exploring this first. Thanks, John
