|send_file and very large files||theG||4/23/10 1:14 PM|
I am using sinatra and send_file for a download process. Versions as
[2010-04-23 20:51:43] INFO WEBrick 1.3.1
== Sinatra/1.0 has taken the stage on 8030 for development with backup
[2010-04-23 20:51:43] INFO ruby 1.9.1 (2009-12-07) [x86_64-linux]
When i serve a large file say 500MB, sinatra seems to take ages to
start 'streaming' it. ie. in IE and FF the prompt does not come up for
a while (or not at all).
Now i read something about streaming and send_file is supposed to
chunk 8K or something. But it doesn't look like it's working. Also i
read about proxying the request to say apache.
1) is something wrong with send_file ?
2) how do you do the proxying thing to apache. i need the external url
to not detect the fact that something else is serving the file

I was also seeing the same thing. After a bit of exploring, I think
this is only a problem with Webrick and Thin. If you run Mongrel or
Passenger, send_file should work properly and stream the contents of
the file without first reading it all into memory. Perhaps this caveat
could be documented in send_file's API docs?
Here's a thread about Thin's issue with Rack and streaming files:

it seemed to have worked. i had to patch one of the source files in
mongrel under ruby 1.9.1.
