RubyForge: Mongrel: File Release Notes and Changelog

Notes:
Release Name: 0.96.0

Notes:
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.

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

Changes:

This release includes small changes for things allowed by Rack
1.1.  It is also now easier to detect if daemonized process
fails to start.  Manpages received some minor updates as well.

Rack 1.1 allowed us to make the following environment changes:

* "rack.logger" is now set to the "logger" specified in
  the Unicorn config file.  This defaults to a Logger
  instance pointing to $stderr.

* "rack.version" is now at [1,1].  Unicorn remains
  compatible with previous Rack versions if your app
  depends on it.

While only specified since Rack 1.1, Unicorn has always exposed
"rack.input" in binary mode (and has ridiculous integration
tests that go outside of Ruby to prove it!).

    unicorn 0.96.0 - Rack 1.1 bump
    
    This release includes small changes for things allowed by Rack
    1.1.  It is also now easier to detect if daemonized process
    fails to start.  Manpages received some minor updates as well.
    
    Rack 1.1 allowed us to make the following environment changes:
    
    * "rack.logger" is now set to the "logger" specified in
      the Unicorn config file.  This defaults to a Logger
      instance pointing to $stderr.
    
    * "rack.version" is now at [1,1].  Unicorn remains
      compatible with previous Rack versions if your app
      depends on it.
    
    While only specified since Rack 1.1, Unicorn has always exposed
    "rack.input" in binary mode (and has ridiculous integration
    tests that go outside of Ruby to prove it!).

    http_response: disallow blank, multi-value headers
    
    The HeaderHash optimizations in Rack 1.1 interact badly with
    Rails 2.3.5 (and possibly other frameworks/apps) which set
    multi-value "Set-Cookie" headers without relying on the proper
    methods provided by Rack::Utils.
    
    While this is an issue with Rails not using properly, there
    may be similar apps that make this mistake and Rack::Lint
    does not guard against it.

    launcher: no point in sync-ing $stdin
    
    Inspection of the MRI source reveals that IO#sync=true only
    appears to only apply for writes.  Though it could eventually
    make sense to disable read buffering by setting IO#sync=true,
    it does not appear to happen.
    
    Of course we never read from $stdin anyways....

    Rainbows! does not yet know about ready_pipe, and will probably

    clarify errors when listeners fail to bind
    
    When using multiple listeners, the log messages can be
    potentially misleading as to which listener fails to bind:
    
    Before:
    
      INFO -- : unlinking existing socket=/tmp/unicorn.sock
      INFO -- : listening on addr=/tmp/unicorn.sock fd=3
      unicorn/socket_helper.rb:110:in `initialize': Permission denied - bind(2) (Errno::EACCES)
    
    After:
    
      INFO -- : unlinking existing socket=/tmp/openxdms.sock
      INFO -- : listening on addr=/tmp/openxdms.sock fd=3
      FATAL -- : error adding listener addr=0.0.0.0:84
      unicorn/socket_helper.rb:110:in `initialize': Permission denied - bind(2) (Errno::EACCES)

    launcher: descriptive error message on startup failure
    
    Rather than erroring out with a non-descript EOFError,
    show a warning message telling users to check the logs
    instead.

    Avoid leaking ready pipe file descriptor to workers
    
    Otherwise the original spawner process may not notice the close
    as it's still being shared by workers.  While we're at it, avoid
    confusing the original spawner by using readpartial instead of
    sysread.

    exit with failure if master dies when daemonized
    
    This behavior change also means our grandparent (launched
    from a controlling terminal or script) will wait until
    the master process is ready before returning.
    
    Thanks to Iñaki Baz Castillo for the initial implementations
    and inspiration.

    bump "rack.version" env to [1,1]
    
    This will match what's in Rack the 1.1.0 release.

    recommending Dir.chdir and Process::UID.change_privilege
    is bad.

    set env["rack.logger"] for applications
    
    rack.git upstream has it, so it will likely be in Rack 1.1
