I''ve had a right fun few days at work trying to figure out why our Rails app (which isn''t under very heavy load) kept eating memory and bringing our server to our knees. Eventually I traced it to send_file (which was in a way a relief as it wasn''t down to my coding ;) -- every time a user started downloading, the memory consumed by the app would jump, and

I''m writing an app for a blood exam center, where people can go and check the results without going physically there. The customers log in the system and a pdf download is offered to them. The downloads though will not be stored in the db but in the filesystem. How can I allow people to download files only if they''re authorised? I obviously can''t store all the files in

Looking at the code for ActionController#send_file I see that it is using ruby to send the file contents. Linux supports a sendfile() OS call. The implementation of Linux sendfile() is extremely fast and very CPU efficient, far faster than what can be done in user space. Does Windows support a sendfile() equivalent call? I haven''t been working with ruby long enough to know how it handles

Hi there, I am working in a RoR application which allows certain users to upload files. Currently I store these files in a directory called "files". This directory is located in the RoR application directory: rails/rails_application/files So users don''t have access to them. Now I want users to be able to download some of these files (they will search based on some

Greetings all, I''ve got an app in production at dreamhost, but I can''t seem to force FCGI on it. I have it enabled for the domain in the admin panel, have checked the file permissions in my public folder, and tried firing the scripts from the command line. When firing either dispatch.cgi, or dispatch.fcgi from the command line, I get a 500 internal server error on BOTH.

I''m having tons of problems with fcgi on apache2. The app didn''t crash over the weekend when it wasn''t used. I ran it this morning and it was fine. It''s an inhouse app so it wasn''t used for 3 days over the weekend. It did however crash today. Does this sound like a bad fcgi setup or just a very buggy fcgi/Apache combo? Charlie Bowman

I installed mod_fcgid yesterday. It works great for my Rails app. But in my fastcgi.crash.log is constantly get this output: [23/May/2006:08:12:07 :: 29040] starting [23/May/2006:08:18:48 :: 29040] asked to terminate immediately [23/May/2006:08:18:48 :: 29040] terminated by explicit exit [23/May/2006:08:22:03 :: 29391] starting It also shows up in the Apache error log. Is this normal? Or should I

Hello all. Time for an all night installation campfire (no pun intended) story. I just helped a customer migrate from a single box to a 5 box system. 2 Lighty 2 FCGI 1 DB Everything went quite well. I scripted everything so it would be easy to add more boxes in the future. 3 scripts, one for each box type above. Then came time to get the site working. :-) Lighty came up easily. The DB came up

Hi All, has anyone ever seen it when they vist the URL in the applicaion that it just tries to download the FCGI dispatch file?

Hi, I just installed mod_fcgid on my apache2 server. When I try to load my application I get an "Application error - Rails application failed ..." message. In my Apache2 error-log it says: Premature end of script headers dispatch.fcgi mod_fcgid process /data/www/app/dispacth.fcgi exit (communication error), terminated by calling exit(), return code 1 Any help with this would be

Hi, i''m wondering how to setup a staging site for my RoR app. Right now i run webrick on my laptop to develop, then i svn commit my changes to the production server. However i need to make my development environment available to others and not just for me on my laptop. I have RoR setup on a hosted vps server which runs in production environment. Its on apache 1.3 and mysql. How can i

Hi there, The default recipe expects you to be able to access your web server directly from your local machine. On our web server, for security purposes, it is only possible to ssh to it through one particular ip (which is also a remote machine.) The capistrano source is so compact and tidy it looks very hackable. But rather than messing around I thought I''d ask first if anyone else

I''m having trouble uploading 2+ files simultaneously (from different client machines)... the upload page just hangs... I''m running... - ruby 1.8.4 (2005-12-24) [i686-linux] - rails 1.1.4 - red hat el 4 - apache - fcgi (0.8.7, 0.8.6.1) - firefox 1.5.0.5 - httpd.conf <IfModule mod_fastcgi.c> FastCgiIpcDir /tmp/fcgi_ipc/ AddHandler fastcgi-script .fcgi FastCGIConfig

Hi I am running ruby 1.8.4 and rails 1.0.0 with Apache 2. I made a simple rails application called demo and also created a controller called say and an action called hello which is working fine using webrick. To run it under Apache I created a symlink demo1 which is linked to the demo/public directory. If I run it using www.example.com/demo1 then I get the "Rails- Welcome Aboard"

Hello, It seems that there is a small probability of collisions among uuid''s produced by uuidtools'' UUID.random_create() running in concurrent user processes on a host (fcgi)? The ~2 bytes extracted from the randomized clock_sequence make a collision unlikely. http://rubyforge.org/frs/download.php/8572/uuidtools-1.0.0.zip Do I miss something? DD -- Posted via

I''m doing a fotolog for a company. It''s expected to manage about 100k of connections per day and about 1500 concurrents connections. What hardware should I buy to manage those numbers of connections? I''m planning to use slackware + lighttpd + fastcgi, but perhaps we will have to reuse some scripts in php, in that case I would use slackware + apache + mod_php + fastcgi

Why isnt the RoR community focusing on robust and scalable mod_perl style of Apache environment, rather then splintering all over the place with lighthttp, mongrel, WEBrick, SCGI, fcgi, etc??? Its frustrating as someone who is trying to migrate to RoR. Its very unlikely I would ever get a contract to work on any webserver except Apache, so it would seem logicaly to focus all our efforts to

If I were to serve files, would send_file via rails be slow? I think they will be 200mb avi files. Would it be better to send them via /public ? But I would like to track the clicks on each file - which makes me think that I can''t serve them out on /public as those clicks will not go through my application. Any help or suggestions? -- Posted via http://www.ruby-forum.com/.

Following the instructions on Hivelogic, everything works flawlessly on my Powerbook until I do the ''sudo gem install fcgi. I''m getting no-definition errors all over the place.
