similar to: send_file and locking files after download?

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 have an application which uses send_file to send a ZIP file to the client. This works nicely when it''s run on our development OS-X boxes, using mongrel from script/server, but on our production server, using mongrel behind Apache 2.2. with mod_proxy_balancer, the client gets 1 byte delivered :-( If I use wget -S to the URL in order to see the full headers I see this on

forgive me if this has been resolved already... I have an app that is using sendfile to return large files to customers. We can''t use regular Apache to handle this static content since the files are what the customers are paying for - so it wouldn''t be cool for anyone else to get access to them. The issue is that the mongrel mem footprint gets bloated when the files are

I''m attempting to use send_file to send an image file from public/images. The file is world readable. I keep getting the following error: A ActionController::MissingFile occurred in account#current_logo: Cannot read file public/images/logo.png /usr/lib/ruby/gems/1.8/gems/actionpack-1.12.1/lib/action_controller/streaming.rb:55:in `send_file'' I''ve tried supplying

Or perhaps I am stumbling in newbie fashion (tho I have active_merchant and a store site basically up and running in development mode - still I don''t feel I always understand what is going on.) So, when I have send_file(filename, :type => ''application/x-zip'') redirect :action => index the send_file seems to hang, rather than complete. I''m deducing

Hi, I''ve been using send_file in my Rails application with WEBrick happily to send files of various sizes and kinds. The same code fails to send anything but a 500 error when run under Apache, and a log file message "warning: syswrite for buffered IO". Looking back through the mailing list archives I see that there have been send_file bugs in the past. Can some knowledgeable

Hello guys, I am having the option to download certain folders on my app in zip format. So every time a user requests one I''m doing a system call to zip the folder (ex: system(''cd ''+path+'' && zip ...) and then the send_file method to send it. What happens is that I''m keeping track of disk space so I need to delete the zip immediately. I was

I''m trying to add a link to download a zip file. I created a controller method that makes the call to send_file: def getzip send_file ''file.zip'' end When I navigate to this link I get a MissingFile exception. The file definitely exists (and U triple-checked paths and spelling) and the permissions are 644. I tried moving it to the /public folder and updating the

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

So this is the original code I used, and it worked send_file ''vendor/sprites/not-found.png'', {:filename => "sprite-not-found.png", :type => "image/png", :disposition => "inline"} Now I switched it to this (going to be adding imageMagick) send_data File.read(''vendor/sprites/not-found.png''), {:filename =>

Quirky stuff here, The current setup works fine for Firefox 3.6 and IE 8 but balks on earlier IEs. The files are PDFs, .doc files, and other binaries but up to several MB: A. the users'' problem is a minor IE7 quirk: it works to download files from clicking links, but if you use the URL instead then the browser stops after a fraction of a second. Refreshing or hitting Return again

Hi- I''d like to load a PDF file into a page, in my controller: send_file "/path to/my.pdf", :disposition => "inline" However, instead of rendering inline, it asks to download the file.
