I am just getting into web servers/web applications and rails as well so bear with me. I am trying to write a web app that, based on a users input from the browser, will perform some task, and update the browser (ala ajax style) as needed and/or provide a way for the user to control the background task. Now, I have more experience with java servlets, which makes this easy enough for a beginner.

Does anyone know whether the mongrel upload progress plugin works with nginx? It works fine for my app under pound, but not with nginx. I am using DRb to handle the uploads as detailed at http://mongrel.rubyforge.org/docs/upload_progress.html . If I am using pound I can see the uploads with irb -r lib/upload_client.rb , but cannot if I am using nginx. Does anyone know anything more about this

My application is going to have a work queue of scheduled tasks stored in the DB. This work queue will be shared across multiple Rails app servers. I need a way to ensure that no two servers get the same jobs if multiple servers pop jobs off the top of the queue simultaneously. Is there a fairly simple way to acheive this? Or do I need to come up with some fancy secondary server to dispatch

Folks- I just commited another revision of the plugin. Nothing huge in this update but some extra features. Acl lists are now configurable in the config file. So you will want to blow away and recreate your config file again. Thanks to Georg Friedrich for this. And I applied Gunter Ladwig''s patch for singleton worker classes. These are workers that only have one instance of

I have looked through the docs, looked at the code, even gave a cursory (2 page) glance at google, and it is not clear to me what SpecServer is or what it is for. Is it meant to speed up the execution of specs in a rails environment by doing some magic on the database? Or I am thinking it keeps a copy of Rails running to avoid the rails reload delay... Is there any documentation on this so I

Hello, Thank you so very much for Backgroundrb. Good Stuff. A general question: Do: - calling ''teminate'' within a worker - calling delete_worker through MiddleMan - letting the :ttl expire - calling MiddleMan.gc! (with an appropriate timestamp) All accomplish the same thing? And here''s a bonus feature request: It''d be cool if you could specify how many

I ma trying to get this upload working, http://mongrel.rubyforge.org/docs/upload_progress.html, ....after starting from the command line, mongrel_rails start -d -p 3001 -S config/mongrel_upload_progress.conf I get this eror in the browser, NameError uninitialized constant UploadProgressRailsController RAILS_ROOT: /usr/opt/tomcat/workspace/upload/config/..

I''m using a cluster of mongrels behind an apache 1.3 proxy pass. I''ve been passing the request to pen, which in turn balances the cluster of mongrels. Now, I''d like to be able to use a different server to send the static files created by the rails application, so I tried to replace pen with nginx. Everything seems to work fine except the environment variable REMOTE_ADDR.

Hi everybody, I just suscribe to the list because I have a problem using mongrel and mongrel_cluster... I setup a server (debian unstable wich provide apache 2.2.3 as a pakage) but I have an error when I try to access my application : ERROR 403 : Forbidden, You don''t have permission to access / on this server. When I check apache''s logs I found that : [warn] proxy: No

I just switched to Mongrel, and it''s been working much better than my previous lighttpd/fastcgi setup. So thanks for the awesomeness. My current problem: once or twice an hour, I get following error in production Mongrel timed out this thread: too many open files I never get it in testing or on our staging server. Any ideas what would cause that? It doesn''t *appear*

I blogged about some of the problems with aaf in production (http://www.jroller.com/BrightCandle) yesterday but inspired by the poitive response I thought I would share the perceived problems and discuss some of the potential solutions to help newcomers and make aaf work as if by magic just like Rails does. All of these problems boil down to one simple problem, running acts as ferret in a

Hi, Are there any recommendations as to what is currently the most stable setup is for mongrel & apache? I read somewhere (probably here) that you should avoid using PStore for sessions. Are there any more of such recommendations? Also, what is currently the safest version of mongrel to use in production? Jeroen

I have a very strange problem here. I do not get this. So any help is greatly appreciated. Basically I have a model that calls a method in the background process in the "after_save" method. Let''s call the model products. So what happens is this: 1. I create a new product. 2. Everything works and the product is saved with id 13. 3. A method is called in my background

Hi all, Tried out the mongrel upload progress plugin with Drb and it works great on my OSX development box, but when putting it into production (Ubuntu Dapper), uploads complete but the app isn''t returning any values for upload progress, and uploads are not showing up in the queue when running upload_client.rb. Before anyone asks, yes, I''m running both the mongrel instances and

I''d like to use Mongrel_cluster with SSL on a green-field application (it can be configured however is best - initially, "ease of setup" is important, but then soon after will be scaling and response time). I''ve read a lot of emails on this topic, and checked out the Mongrel pages, etc, but I''m left with this question of what is recommended: For a

Alright folks, after nearly a month of pounding and beating up the Mongrel 1.0 RC1 release we''re putting out the official 1.0.1 release. Read all about it at the (much funnier) news posting: http://mongrel.rubyforge.org/news.html For those people in a hurry, the gems should hit the mirrors and you can install using your usual commands. Refer the the above page for more help.

Hi all, If you are using Pound / Pen or another load balancer, I believe you should read this: http://blog.teksol.info/articles/2006/08/25/subversion-metadata-exposure-on-mongrel My article refers to Dan Benjamin''s http://hivelogic.com/articles/2006/04/30/preventing_svn_exposure My point is that even though we are preventing Apache from serving anything except a select few file

I wrote an x-sendfile thing for the railshandler to get mongrel to catch the response header and stream out files from an application I''m writing but I''m pretty sure that zed said he''d built in x-sendfile somewhere already. I couldn''t find it, could someone lead me to it? Does mongrel work with SSL? If not is anyone interested in having someone write in SSL

I''m trying to do some initial benchmarking of our setup, mainly just to establish baselines. I''m essentially using the process Zed outlines in a previous message: http://rubyforge.org/pipermail/mongrel-users/2006-May/000200.html What I''m running into is that Mongrel appears only half as fast as Apache when serving a small static HTML file. If I then add in Apache with

Hi all, I just wanted to let you know that I built some Debian (Sarge) packages to allow an apt-get only installation of Mongrel, Ruby and friends. Also contained is an init script that is capable of managing multiple applications. Support for the Pen load balancer is also included. More info can be found there:
