Hello Michael, Thank you for your reply.

ResponseIO enables to choose a function which sends files with minimum system calls for WAI users.

I have already implemented this both in wai and warp, and confirmed that this works well.

Obviously getting sendfile and Warp to be more efficient should be a goal here (which I know you're already following up on). My question is, barring issues with the sendfile package, is there any other use case for this constructor? I'm hesitant to add it, because it does not have a natural implementation for anything but a standalone server (i.e., CGI, FastCGI, wai-test will always have trouble with this). I just want to clarify the need before we make any changes.

If the sendfile library will be faster, this constructor is not necessary. I also agree that making the sendfile library faster is a right way to go. But I cannot contact the authors of the sendfile library. Do you have any advices on what I should do? --Kazu

Hello,

Well, if the authors of sendfile aren't responsive, another possibility would be to have Warp use your more efficient sendfile code directly (either by releasing it as its own package, or by moving that code into the Warp codebase). I would prefer this approach to changing WAI. Thoughts?

Please tell me which OSes Warp should support? I can provide sendfile functions to Linux/FreeBSD/MacOS but I cannot do for Windows. If Unix-like OSes are enough, I will take this approach. --Kazu

Conditional compilation should work fine but IIRC conditional dependencies aren't supported. You'll probably need to retain the sendFile dependency even if you integrate 山本様's code. Then just use his via conditional compilation as an optimization. Max On Jun 7, 2011, at 13:23, Michael Snoyman wrote:

I think it should be possible to use conditional compilation to use your code for relevant OSes, and otherwise fall back to the sendfile package.
