Recently I've seen several suggestions on this list for the enabling of "use sendfile" as a means to improve throughput. I thought this was peculiar since the doc says it is enabled by default. I guess it isn't. On both RHEL4 (Samba v3.0.10) and Fedora Core 4 (Samba v3.0.14) the entry for "use sendfile" in the smb.conf says: Default: use sendfile = yes Hmm.

Hi everyone, I try to use the "X-Sendfile" header, but it doesn''t work as expected. In my controller: path = "/home/bruno/file.tar.gz" headers[''X-Sendfile''] = path headers[''Content-Type''] = "application/octet-stream" headers[''Content-Length''] = File.size(path) render :nothing => true When I request

Aloha. The current CVS snapshot and 1.0-test14 will not build on Solaris 8 because it does not provide a sendfile() funtion. It just has sendfilev(). Solaris 9 has sendfile(), though. Using the old sendfile-util.c from 1.0-test1 and setting HAVE_SOLARIS_SENDFILEV instead of HAVE_LINUX_SENDFILE in config.h works. Greetings, Andy.

Hi Folks, I''ve been getting reports of people with serious stability problems in Mongrel. These problems go away instantly when they remove ruby-sendfile. If your mongrel starts up saying that you have "sendfile installed" and that it is using it then **you are wrong**. Remove the gem and don''t use it. I''ll be investigating why it doesn''t really

Hi I''m currently trying to use X-Sendfile to take some load off my rails app, unfortunately in my development environment mongrel is happily passing through the x-sendfile header, presumably for the (non- existant) proxy to handle the header. Is there some way to make mongrel process the x-sendfile header itself? Thanks jebw

I have found a package called sendfile that let you send files over network. It installs a prog called sendfile to send and a daemon called sendfiled, called on demand by inetd. I''d like to know if this package is security safe C.Leroy Source can be found at URL: ftp://ftp2.ibp.fr/pub/linux/sunsite/Incoming/sendfile-1.5.tar.gz

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 -

I wrote an x-sendfile thing for the railshandler to get mongrel to catch the response header and stream out files from an application I''m writing but I''m pretty sure that zed said he''d built in x-sendfile somewhere already. I couldn''t find it, could someone lead me to it? Does mongrel work with SSL? If not is anyone interested in having someone write in SSL

This is a short summary of an experiment that I did for the linker. One of the major tasks of the linker is to copy file contents from input object files to an output file. I was wondering what's the fastest way to copy data from one file to another, so I conducted an experiment. Currently, LLD copies file contents using memcpy (input files and an output file are mapped to memory.)

I have a fix for the sendfile.c code for HP-UX - length not properly specified prior to call. I've also added code to support the AIX send_file() function and configure.in code to check for AIX specific send_file API and sets AIX_SENDFILE_API if successful. Could you consider this patch for 3.0.11? I also sent a web/cgi.c patch for "struct var" last week with respect to compile

Hi all, sendfile() could be enabled in NGINX(https://www.sobyte.net/post/2022-08/nginx-send/). It could improves the performance since it could optimize to transfer data to user space. Up to now, sendfile() isn?t supported in OpenSSH yet. Will it be supported in the future? Best Regards Haojian

Greetings! Is there a way to get RoR to redirect_to another action after doing a sendfile? My little app lets the user enter a bunch of data and then creates an XML file from it. I''m using sendfile to let the user download the XML file. Once they download the file I want to take them to a new view that presents a logout button that will trigger a cleanup. But it looks like RoR

Looking at the code for ActionController#send_file I see that it is using ruby to send the file contents. Linux supports a sendfile() OS call. The implementation of Linux sendfile() is extremely fast and very CPU efficient, far faster than what can be done in user space. Does Windows support a sendfile() equivalent call? I haven''t been working with ruby long enough to know how it handles

Mates, I'm trying to learn a little more. I have 3.0.7 running on Mandrake 7.2. I could see all the shares, but couldn't access the files "sendfile failed". I set use sendfile = No and all is well. I have a separate system Suse 9.0 pro with use sendfile = yes and I have no problems. What is the difference??? -- David C. Rankin, J.D., P.E. RANKIN * BERTIN, PLLC 510 Ochiltree

I''ve had a right fun few days at work trying to figure out why our Rails app (which isn''t under very heavy load) kept eating memory and bringing our server to our knees. Eventually I traced it to send_file (which was in a way a relief as it wasn''t down to my coding ;) -- every time a user started downloading, the memory consumed by the app would jump, and

forgive me if this has been resolved already... I have an app that is using sendfile to return large files to customers. We can''t use regular Apache to handle this static content since the files are what the customers are paying for - so it wouldn''t be cool for anyone else to get access to them. The issue is that the mongrel mem footprint gets bloated when the files are

Why in smbd/reply.c does send_file_readX only use sendfile if write cache size is 0? <snip> if (chain_size ==0 && (CVAL(inbuf,smb_vwv0) == 0xFF) && lp_use_sendfile( SNUM(conn)) && (lp_write_cache_size(SNUM(conn)) == 0) ) { </snip> While its true send_file_readX works regardless of the state of oplocks (which is cool!) the smb.conf.5

As to leave an opportunity for the kernel, I think mmap+write would be enough. Because the kernel knows what address is mmap'ed, it can detect that write's source is actually a mmap'ed file and if that's the case it can optimize as it does for sendfile. It seems that Linux doesn't do that now, though. I haven't thought about using non-temporal stores. It may work as we

Hey, We are blocked on a bug fixed by RHEL in https://rhn.redhat.com/errata/RHBA-2012-0362.html. Specifically, the splice code in sendfile() incorrectly updating the offset position on the write side, Red Hat BZ#771868. I have not been able to figure out if this bugfix is included in any CentOS releases. If you are better at reading release notes than me, could you please help me out and let me
