Rails "render: text => proc" in 2.2.2 and 2.3.2
I am experiencing something that I cannot explain with Rails 2.3.2. I created a new application with one controller and one action to narrow it down. My entire controller is as follows.
class LinesController < ApplicationController
def show
respond_to do |format|
format.html { render :text => proc {|response, output|
10.times do |i|
output.write("This is line #{i}\n")
output.flush
end
}
}
end
end
end
When I run this under Rails 2.2.2, I see the following answer.
$ curl http://localhost:3002/lines
This is line 0
This is line 1
This is line 2
This is line 3
This is line 4
This is line 5
This is line 6
This is line 7
This is line 8
This is line 9
However, when I run it under Rails 2.3.2, I get this instead.
$ curl http://localhost:3002/lines
curl: (18) transfer closed with outstanding read data remaining
If I hit this with a browser, I only see the first line.
This is line 0
Please note that my sample code is directly from the Rails documentation for render , except that I have reduced the number of lines from 10 million to 10.
I suspect the answer lies somewhere in the flush () method, but I'm currently stuck trying to dig up the explanation from the source code.
