From 0adbeeb0c92c6de2e4a148e4b54d56cd4a325800 Mon Sep 17 00:00:00 2001 From: Yehuda Katz Date: Mon, 10 Aug 2009 11:40:41 -0400 Subject: Got overhead down from 127 to 85. All tests pass: * Tentatively replaced HeaderHash with SimpleHeaderHash, which does not preserve case but does handle converting Arrays to Strings in to_hash. This requires further discussion. * Moved default_charset to ActionDispatch::Response to avoid having to hop over to ActionController. Ideally, this would be a constant on AD::Response, but some tests expect to be able to change it dynamically and I didn't want to change them yet. * Completely override #initialize from Rack::Response. Previously, it was creating a HeaderHash, and then we were creating an entirely new one. There is no way to call super without incurring the overhead of creating a HeaderHash. * Override #write from Rack::Response. Its implementation tracks Content-Length, and doing so adds additional overhead that could be mooted if other middleware changes the body. It is more efficiently done at the top-level server. * Change sending_file to an instance_variable instead of header inspection. In general, if a state is important, it should be set as a property of the response not reconstructed later. * Set the Etag to @body instead of .body. AS::Cache.expand_cache_key handles Arrays fine, and it's more efficient to let it handle the body parts, since it is not forced to create a joined String. * If we detect the default cache control case, just set it, rather than setting the constituent parts and then running the normal (expensive) code to generate the string. --- actionpack/lib/action_controller/metal/streaming.rb | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'actionpack/lib/action_controller/metal/streaming.rb') diff --git a/actionpack/lib/action_controller/metal/streaming.rb b/actionpack/lib/action_controller/metal/streaming.rb index 57318e8747..4761763a26 100644 --- a/actionpack/lib/action_controller/metal/streaming.rb +++ b/actionpack/lib/action_controller/metal/streaming.rb @@ -145,7 +145,6 @@ module ActionController #:nodoc: def send_data(data, options = {}) #:doc: logger.info "Sending data #{options[:filename]}" if logger send_file_headers! options.merge(:length => data.bytesize) - @performed_render = false render :status => options[:status], :text => data end @@ -175,6 +174,8 @@ module ActionController #:nodoc: 'Content-Transfer-Encoding' => 'binary' ) + response.sending_file = true + # Fix a problem with IE 6.0 on opening downloaded files: # If Cache-Control: no-cache is set (which Rails does by default), # IE removes the file it just downloaded from its cache immediately -- cgit v1.2.3
