Hello all, Are you aware of the rails ActionController::Base.allow_concurrency option ? If this option is true, rails is able to process simultaneous multiples actions. It appears that rails is thread-safe (if the user application is), and that this option is mostly unknown. Webrick take care of this option in rails-1.1.2/lib/webrick_server.rb at line 80 : REQUEST_MUTEX.lock unless

We are *days* away from the official 0.3.13 release, which will be followed quickly by 0.4 code named Enterprisey Edition 1.2. This latest pre-release update closes off the last of the annoying bugs, and adds one very nasty feature people should check out before we release. Read about Katanas below. ** This release doesn''t have win32 yet. That''ll be uploaded Monday. ** WHAT

Hello Zed ! I''ve experimented a simple but limited performance tweak in the mongrel rails loader. With the following apache 2.2 mod proxy loadbalancer setup : # Redirect all non-static requests to cluster RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f RewriteRule ^/(.*)$ balancer://mongrel_cluster%{REQUEST_URI} [P,QSA,L] We can assume that mongrel is called only when the

Hello Everyone, Francois Simond inadvertently found a way to replicate a rare but deadly bug right as I was working up the official release of Mongrel 0.3.13. This bug only happened to a few people, but thanks to the wonderful fuzzing tool Apache Bench[1] he could replicate the slow select starvation people were seeing. TESTING This bug is now fixed in the current pre-release, and I''d

Hi, I just found something weird for mongrel with static files. Performance endlessly decreases if mongrel serve static files from simultaneous requests : Here is the test setup: Ruby on Rails Mongrel (tested with 1.3.12.4 and 1.3.13-pre installed today) Ubuntu dapper, compiled ruby 1.8.4. http client : while true; do ab -n 1000 -c 30 http://localhost:3000/ 2>/dev/null | grep

Hello Everyone ! Wanted to announce the launch of a new, 100%, Ruby/Rails based shopping system. http://www.rightcart.com (our blog: http://www.rightcartblog.com) It''s basically a shopping widget that allows users to make purchases directly through the widget.... no need to be redirected to a third party shopping cart. You can sell anything you want by upload the products onto the

Hi All, I''m hosting with MediaTemple who are currently using 0.3.3 of mongrel on their GridServer. My rails app has an image upload facility whereby if you upload a large image (e.g. 5Mb) mongrel crashes. I''ve requested an upgrade to the latest version of mongrel but don''t believe that''s going to happen too soon. I''m not getting too much

Hi All, I''ve got a DomU that sometimes goes mad. I can''t ssh or usually even console to it. The time I did manage to console I got a load of dumps about being out of memory and swap, but couldn''t run any commands to find out which process had gone mad :( From Dom0 I can see the DomU at 100% CPU and can only stop it with a destroy. What can I do/check to find

I know I love the new RJS templates but the one annoying thing is that I don''t get the nice Rails error pages anymore when something goes wrong. I wrote up an article with a code snippet for fixing that. Hopefully it will help out some of those as frustrated as I was. http://www.height1percent.com/articles/2006/04/21/improving-debugging-for-ajax-and-rjs -- Posted via

Out of memory? We?ve definitely seen similar symptoms (it?s been a while, so I?m not sure they were identical) for compute nodes running large memory jobs. Noam

Hi everyone, It took me a while to figure this out properly, as I kept getting circular or missing dependencies with video drivers. This set of three patches should simplify the situation a bit, mostly by cleaning up the dependencies around CONFIG_ACPI_VIDEO. With all three patches applied, I no longer run into those related warnings. If everyone agrees on the general direction, I hope we can

Hi all, there was a recent thread[1] on rails-deploy about Ferret in which a lot of people complained of problems using it in production. I''ve been using Ferret (with DRb) for many months now with no serious issues. I''m assuming the posters know what they''re doing so I''m guessing they''re just using Ferret in higher-scale environments than me. I

Hi! I''m using the latest&greatest backgroundrb with rails 2.0.2 on ubuntu dapper. I''ve made an app that lets you run a query on several servers at once, which are selected at runtime. Therefore, for each server that is selected, I spawn a new worker and assign its work. After everything is completed, the workers are deleted. I often get this error:

While we were trying out a new capistrano setup tonight we noticed that the spawner would alternately spawn fcgi processes, then the next time it would kill them, then create, then kill, etc... >From everything I can see/read/know, spawn-fcgi should not affect running processes, right? Anyone else see this weird behavior? For now we are using the ''check the port before
