similar to: LLD: Using sendfile(2) to copy file contents

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

I now have an implementation of FileOutputBuffer (OutputBuffer was already taken).

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.

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.

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

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

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

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 -

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

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

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

Hello Experts: I understand from the samba code (3.0.25) that we use sendfile during client's Read operation. Is there a reason for not using the same for write operation? Is it to do with header processing etc. Thanks for your feedback!

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

Hello, I had problems with speed of Samba, so I was looking for some solution and I had discovered "use sendfile" configuration option. I was checking all Samba release notes and I had discovered, that from some version (older than is in CentOS repo) this option was turned on as default. So my question is, why in CentOS 5.3 is that option in default set to off? Thank you for responses

Hey - I need your input regarding a problem I''ve come across. I''ll first explain what the problem is, and what I think the solution is. If I misunderstood how things work, please let me know. # The problem I''m using Dragonfly (on-the-fly file processing) to serve images. Dragonfly uses Rack::Cache to cache the processed images so subsequent requests are served by

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

i wrote a little camping app which serves the css, js and images statically using the Static class example i found on the camping wiki. everything works perfectly on my mac. once on windows the static files don''t get served. a 404 is returned. i have tried running the app using camping, webrick and mongrel, all give the same 404 response. here is an example value of X-Sendfile.
