similar to: Rack-Cache and Streaming... incompatible?

Hey - I need your input regarding a problem I''ve come across. I''ll first explain what the problem is, and what I think the solution is. If I misunderstood how things work, please let me know. # The problem I''m using Dragonfly (on-the-fly file processing) to serve images. Dragonfly uses Rack::Cache to cache the processed images so subsequent requests are served by

I know that we can use config.exception_app to set up custom exception handling and also use rescue_from. However, I have an issue that there is malformed request (testing generated request) that caused Rails Rack middleware to throw an exception when Rack''s parse_query method. Here is the detail of the problem:

I am working on a streaming download (CSV) from Rails 3.2 and am coming up against an issue of the initial page request taking a long time. The following controller code illustrates my issue: self.response_body = Enumerator.new do |y| 10_000_000.times do y << "Hello World" end end With the above, the response does seem like its streaming

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. Now I''m getting the Purple "Ruby (Rack) application could not be started" screen with Error: no such file to load -- rack Application: /data1/rack/puppetmaster The backtrace is uninspiring.

Hi, I''ve been trying to incorporate https://github.com/wycats/rack-offline into my app. I followed the example in the readme that shows how to cache application.css and application.js files and that works. When I go to my browser in production mode, though, and turn off my network connection, then reload the app, the app is reloaded successfully, except for the images. I think I

I''m trying to use Camping from Magnus'' repo (1.9.300) but running the blog.rb example (or anything for that matter) gives me Rack::Lint::LintError at / Content-Length header was 0, but should be 548 Ruby C:/ruby-1.8.7/lib/ruby/gems/1.8/gems/rack-0.9.1/lib/rack/lint.rb: in assert, line 16 Web GET localhost/ There are no errors on the camping output so I suspect something has

The Rails on Rack documentation is still using the "ActionController::Dispatcher" class but it no longer exists, I can update the documentation, I just wanted to discuss what''s the best way to do it, I''ve tested with "run Rails.application" as well as with "run MyAppName::Application" (just like the generated config.ru file does it), what do you

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

Hey, I''m not sure I fully appreciate the best use(s) for Rack apps (e.g., Sinatra apps) in a Rails (3.1) application... Scenario: I have in mind a bunch of RESTful controller actions linked to models -- all for providing an API. Approach 1: handle each resource from its own mounted Rack app: + ''Rails 3 in Action'' advises mounted rack apps for Rails APIs because they

I get this error can''t activate rack (~> 1.0.1), already activated rack-1.2.2 It appears that puppet-dashboard uses rack 1.0.1 but passenger 3.0.7 needs to use rack1.2.2 Is there a way around this or make dashboard use rack 1.2.2? -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

Hi, I have a rails 2.3.8 app which has rack 1.1.0. I get parse_multipart error. There''s a new release of rack 1.2.0 which might fix the multipart error. The question is how I upgrade the rack? I froze the rails. I did "gem update rack" and it upgraded rack to 1.2.0. But my rails app still uses rack 1.1. How do I set the rails app use rack 1.2.0? Thanks. Sam -- Posted via

Hi folks, Here''s my basic issue, hopefully this is clear. I''m trying to submit some UTF-8 values in my query string, but they are coming out mangled on the other end. It *seems* like the problem is that what Rack::Utils.unescape() pushes out gets converted to UTF-8 somewhere in the chain (using 3.0.7, and Ruby 1.9.2, by the way), and it''s mangling characters which are

Hi all, sorry for the OT. Is IBM and Dell 42U rack compatible in dimension, rails, etc? Can we put IBM servers into Dell rack? Google says it depends. Much appreciated if you can share your experience. http://www.server-racks.com/why-all-racks-are-not-created-equal.html Thank you.

A big theme from RailsConf a few weeks ago was the arrival of Rack in Rails as of version 2.3. The first topic that seemed to pique developer interest was Rails Metal -- especially the speed bump of using a lighter stack for high volume URIs. While this is a useful upgrade to Rails, the architectural shift provided by Rack brings new flexibility. Read more about the value of mounting Rack
