Rails+Mongrel+Lighthttpd: Ruby-Sendfile Problem

Rails
#1

Hello,

I have a working mongrel cluster and want to use Lighty as the frontend
webserver. I want ligthttpd to deliver the static content.
So I did

gem install sendfile --remote

Everything installed.

But if I run the tests like

gem check sendfile --test --debug

i get the following error message:

Exception `Errno::ENOSYS’ at ./test/test_sendfile.rb:75 - Function not
implemented - sendfile

If I use lighttpd with mongrel and sendfile I do have similary error
messages in my mongrel log.

Does anybody know what is wrong?

Cheers, Feurio

My configuration is:

Debian Sarge
Rails 1.1.2
mongrel (0.3.13.3)
mongrel_cluster (0.2.0)
sendfile (0.9.2)
lighttpd-1.4.11

Means that your OS don’t have it, which I don’t quite get since you’re
running Linux.

My configuration is:

Debian Sarge

^^^ Nobody except debian people knows what this means. Which version of
Linux is it? Can you do uname -a and send me that?

the uname -a output is

Linux v330.v330.vanager.de 2.4.20-021stab028.19.777-enterprise #1 SMP
Wed Oct 19 13:05:01 MSD 2005 i686 GNU/Linux

I don´t understand the missing filesend support, too.

…maybe it is because this is a VPS. Could this be the reason?

No, unless debian went as far as to remove sendfile (wouldn’t surprise
me really). I’ll have to confirm that sendfile is actually in the 2.4
kernel.

looks like there could be a problem with lighttpd and debian 3.1 aka
sarge. i looked for lighttpd and in their project-management “trac” you
can find this:
http://trac.lighttpd.net/trac/ticket/328
seems like your problem could be related to this one, as they keep
getting errors like:
“sendfile failed: Function not implemented”
why don’t you try one of their workarounds or another version of
lighttpd oder kernel!?

none

According to this article sendfile is definetly in the linux 2.4.x
kernel:

http://linux.omnipotent.net/article.php?article_id=11706

Until now I couldn´t specific information about debian sarge & kernel &
sendfile…

Is this functionality something you could turn on and off? Maybe it is
just disabled with my system?
