Message-ID: <20110201214117.GA4059@dcvr.yhbt.net> Hi all, are there real-world examples of people using multiple Transfer-Encodings in the same request? rfc2616 seems to allow it as long as chunked is also used, but we don't have support for anything other than chunked. Heck, the only example I can think of for chunked requests in the request is "curl -T-" to make PUT requests from stdin (I use that every single day, but I don't think the rest of the world does). -- Eric Wong From normalperson at yhbt.net Tue Feb 1 21:58:11 2011 From: normalperson at yhbt.net (Eric Wong) Date: Tue, 1 Feb 2011 18:58:11 -0800 Subject: preliminary reverse proxy Rack application Message-ID: <20110202025811.GA26963@dcvr.yhbt.net> Hi all, since some folks have been interested in reverse proxies, I just pushed this out to rainbows.git http://bogomips.org/rainbows.git/commit/?id=130d086666ccd825fcb13c It's a fairly big patch but basically works assuming the backend is behaving and terminating requests. ----------- commit message ------------- This can be a starting point for developing Cool.io or EventMachine-based reverse proxy applications on Rainbows! Eventually Rainbows! could replace nginx for Unicorn users! Just don't consider this code production ready, yet, at all, it doesn't handle any sort of failover and has no automated tests, yet. --- The RDoc in lib/rainbows/reverse_proxy.rb explains the rest examples/reverse_proxy.ru | 9 ++ lib/rainbows.rb | 1 + lib/rainbows/reverse_proxy.rb | 185 +++++++++++++++++++++++++++ lib/rainbows/reverse_proxy/coolio.rb | 61 +++++++++ lib/rainbows/reverse_proxy/ev_client.rb | 39 ++++++ lib/rainbows/reverse_proxy/event_machine.rb | 46 +++++++ lib/rainbows/reverse_proxy/multi_thread.rb | 6 + lib/rainbows/reverse_proxy/synchronous.rb | 21 +++ 8 files changed, 368 insertions(+), 0 deletions(-) create mode 100644 examples/reverse_proxy.ru create mode 100644 lib/rainbows/reverse_proxy.rb create mode 100644 lib/rainbows/reverse_proxy/coolio.rb create mode 100644 lib/rainbows/reverse_proxy/ev_client.rb create mode 100644 lib/rainbows/reverse_proxy/event_machine.rb create mode 100644 lib/rainbows/reverse_proxy/multi_thread.rb create mode 100644 lib/rainbows/reverse_proxy/synchronous.rb -- Eric Wong From normalperson at yhbt.net Wed Feb 2 21:54:15 2011 From: normalperson at yhbt.net (Eric Wong) Date: Wed, 2 Feb 2011 18:54:15 -0800 Subject: Page request roundtrip time increases substantially after a bit of use In-Reply-To: <20110125213835.GA9421@dcvr.yhbt.net> References: <571697.98064.qm@web63303.mail.re1.yahoo.com> <20110124215440.GA25489@dcvr.yhbt.net> <20110125001107.GA1921@dcvr.yhbt.net> <288407.18061.qm@web63303.mail.re1.yahoo.com> <20110125035048.GA8124@dcvr.yhbt.net> <20110125213835.GA9421@dcvr.yhbt.net> Message-ID: <20110203025415.GA3812@dcvr.yhbt.net> Eric Wong wrote: > Let me know if you or anybody else can reproduce this more reliably or > if you figured it was something unique to your setup.

I know how to keep rainbows happy though. So what I do is make sure that rainbows is tasked with closing all connections ... the client doesn't cut off the long polls; that goes pretty far.

It is based on Unicorn, but designed to handle applications that expect long request/response times and/or slow clients. Zbatery is Rainbows! for people without enough memory to fork() * http://rainbows.rubyforge.org/ * http://zbatery.bogomip.org/ (no that's not missing an "s", Zbatery is single process, get it?) * rainbows-talk at rubyforge.org - both project share the same mailing list * git://bogomips.org/rainbows.git * git://bogomips.org/zbatery.git (Shorter git URLs than before \o/) Changes: Small bug fixes that have been sitting around, not much but it's already been one month since our last release. * Unicorn dependency updated to 3.4.0, so we get IPv6 support and Kgio.autopush support for ":tcp_nopush => true" users. * Optional :pool_size argument is fixed for NeverBlock and CoolioThreadPool users. * Mostly minor internal code cleanups * Sunshowers support removed, it was out-of-date and unmaintained. Cramp remains supported for now. * X-Rainbows-* response headers support removed, nobody used it. There are several new features in this release not documented here. Consider any new features not mentioned in these release notes to be subject to removal/renaming in future releases. -- Eric Wong From ganrendetain79daias at yahoo.com Fri Feb 18 14:25:38 2011 From: ganrendetain79daias at yahoo.com (Jason) Date: Sat, 19 Feb 2011 03:25:38 +0800 Subject: =?GB2312?B?RGlnaXRhbCBQaG90byBFZGl0aW5nIFNlcnZpY2VzIC0gUGhvdG8gQ3V0b3V0?= Message-ID: <325cc0c2-4682-44cb-9fc9-7e65a2f97f9d@LJO-SBS1.ljonj.local> Digital Photo Editing Services : We are a China based Imaging Professionals.
