Unicorn 4.3.0 - Rack HTTP server for fast clients and Unix

Ruby
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.

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.

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.
