From cd8a874d18fe01e11bb57b91186b6c9f712a4b3f Mon Sep 17 00:00:00 2001 From: Eric Wong Date: Thu, 10 Mar 2011 15:06:10 -0800 Subject: switch from IO#sendfile_nonblock to IO#trysendfile IO#trysendfile does not raise exceptions for common EAGAIN errors, making it far less expensive to use with the following concurrency models: * Coolio * CoolioFiberSpawn * Revactor * FiberSpawn * FiberPool This requires the new sendfile 1.1.0 RubyGem and removes support for the sendfile 1.0.0. All sendfile users must upgrade or be left without sendfile(2) support. IO#sendfile behaves the same if you're using a multi-threaded concurrency option, but we don't detect nor use it unless IO#trysendfile exists. --- lib/rainbows/stream_file.rb | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'lib/rainbows/stream_file.rb') diff --git a/lib/rainbows/stream_file.rb b/lib/rainbows/stream_file.rb index 11c84d4..4a77a2f 100644 --- a/lib/rainbows/stream_file.rb +++ b/lib/rainbows/stream_file.rb @@ -1,7 +1,7 @@ # -*- encoding: binary -*- # :enddoc: -# Used to keep track of file offsets in IO#sendfile_nonblock + evented +# Used to keep track of file offsets in IO#trysendfile + evented # models.
