similar to: How to handle exception that is generated in rack middleware before it reach rails app?

I have a Rails app that makes connections to other DBs. There may be multiple users connecting to multiple DBs. The app makes a database connection as part of an action. However, I noticed a problem: there's too many DB connections remaining open, which is causing the DB to not have enough connections remaining for new connections. So the answer is using a shared connection pool.

Hello all, I am using Rails 2.0.2 and Ruby 1.8.7 and I need to make use of rack middleware for integrating an ajax file upload plugin(https:// github.com/valums/file-uploader) with paperclip in Rails( As given in this tutorial:- http://mooooooooooo.wordpress.com/2010/12/03/paperclip-valums%E2%80%99s-file-uploader-and-middleware-continued/). I have referred to the rack-middleware Railscast by

It doesn''t seem like my controller specs are calling my middleware on requests. Has anyone figured out a good way to test middlware with rspec?

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

In 2.3, exceptions raised by controllers under functional tests were by default propagated to the test, but by using rescue_action_in_public! a test could trigger the production, public behavior and then use assert_response or similar to test the expected result. This was implemented via coordination between ActionController::Rescue and ActionController::TestCase::RaiseActionExceptions. This

In Rails 2.3.x, you can override render_optional_error_file like so: # ApplicationController.rb protected def render_optional_error_file(status_code) render :template => "errors/500", :status => 500, :layout => ''application'' end However, Rails 3 no longer has render_optional_error_file. Instead, you need to overriderescue_action_in_public, which I do:

=== 1. Camping on Rack === I''ve just finished rewriting Camping to use Rack in the "core". I got rid of (a little less) than 1kB in camping.rb and removed lots of un-necessary files (lib/server/*.rb, fastcgi.rb & mongrel.rb). bin/camping does now only provide WEBrick, Mongrel and console-support and should only be used in development. It uses Rack::ShowExceptions to catch

I am not sure if this desired feature or not but when we are behind a local proxy ie. Nginx/Varnish then the new ShowException middleware doesn''t seem to properly detect the remote IP address and it appears as if every browser gets a local error page with a stack trace, etc. I''ve opened up a ticket on the rails bug tracker but I also would like to verify that this is in fact a

I was trying to understand how exceptions are caught. There are two rescue.rb files. One is under ActionController. I understand how it is invoked and what it does. But the one under action_dispatch I don''t see how it gets used. I see the autoload for it in actionpack-3.0.3/lib/action_dispatch.rb but I don''t see a Rescue class created anywhere. Can someone help me to

I have a gem, and part of the gem is a piece of rack middleware. In Rails 2.3, I could make the gem set up the middleware without adding anything to config/*.rb in the app. I did this with the following line: ActionController::Dispatcher.middleware.use ''MyMiddleware'' But in Rails 3, this doesn''t work. I''ve tried putting the following into the gem''s

My middleware class "ResponseTimer" doesn''t intercept a request. I don''t know why (the example is from here http://railscasts.com/episodes/151-rack-middleware?view=asciicast; I changed my one a little for Rails 3.2.13 version, the original is for Rails 2.x). So I did as follows: ## in \lib\response_timer.rb ## this is the class of my custom middleware: class

Hi, I just encountered a bit of an issue where we call request.params of an ActionDispatch::Request inside a rack middleware right before a Rails 3.0.3 app. The issue is that the path_parameters never appear in the parameters hash if you call request.params before the rails app. It seems that that the requests.params method memoizes itself in "action_dispatch.request.parameters"

I have a puppetmaster running within passenger+rack. It has been running properly for almost a year and decided to stop working on the weekend.

Hi, unicorn unconditionally sets rack.multiprocess to true in the Rack environment. The Rack spec [0] says the following about the variable: "true if an equivalent application object may be simultaneously invoked by another process, false otherwise." When unicorn is running with a single worker this does not hold so what do you think about setting the variable to false when only a
