[ANN] unicorn 4.3.0 - Rack HTTP server for fast clients and Unix

ruby-talk
1

Unicorn is an HTTP server for Rack applications designed to only serve
fast clients on low-latency, high-bandwidth connections and take
advantage of features in Unix/Unix-like kernels. Slow clients should
only be served by placing a reverse proxy capable of fully buffering
both the the request and response in between \Unicorn and slow clients.

* mongrel-unicorn@rubyforge.org
* git://bogomips.org/unicorn.git
* http://unicorn.bogomips.org/NEWS.atom.xml

Changes:

* PATH_INFO (aka REQUEST_PATH) increased to 4096 (from 1024).
  This allows requests with longer path components and matches
  the system PATH_MAX value common to GNU/Linux systems for
  serving filesystem components with long names.

* Apps that fork() (but do not exec()) internally for background
  tasks now indicate the end-of-request immediately after
  writing the Rack response.

Thanks to Hongli Lai, Lawrence Pit, Patrick Wenger and Nuo Yan
for their valuable feedback for this release.

Changes:

* Call shutdown(2) if a client EOFs on us during upload.
  We can avoid holding a socket open if the Rack app forked a
  process during uploads.

* ignore potential Errno::ENOTCONN errors (from shutdown(2)).
  Even on LANs, connections can occasionally be accept()-ed but
  be unusable afterwards.
