    Rainbows! 4.6.0 - fix unicorn 4.8.0 compatibility

    The unicorn 4.8.0 internal changes unfortunately broke some
    unoffically supported behavior we depended on.  This release fixes
    that, but as a result, we lose compatibility of older unicorn
    versions.  (Oops!, oh well... :x)

    There's also minor bugfixes and documentation updates.

    In order to ease transitions to future versions of the GPL, we are
    now "GPLv2 or later" instead of explicitly GPLv2 + GPLv3(-only).
    The old Ruby 1.8 license remains an option.  If the FSF turns out
    a horrible GPLv4, users are free to continue using GPLv2 or GPLv3.

    unicorn 4.8 compatibility + test version bumps

    Internal reworking of unicorn 4.8.0 completely broke us(!).
    This commit fixes things, but it means we no longer support
    unicorn <= 4.7.  Sorry about that.

    error: silence ETIMEDOUT and EHOSTUNREACH errors

    There's nothing we can do about these errors due to
    network failures and bad clients, either, so do not spew
    a backtrace for them.

    license: allow all future versions of the GNU GPL

    There is currently no GPLv4, so this change has no effect at the
    moment.

    In case the GPLv4 arrives and I am not alive to approve/review it,
    the lesser of evils is have give blanket approval of all future GPL
    versions (as published by the FSF).  The worse evil is to be stuck
    with a license which cannot guarantee the Free-ness of this project
    in the future.

    This unfortunately means the FSF can theoretically come out with
    license terms I do not agree with, but the GPLv2 and GPLv3 will
    always be an option to all users.

    This was documented in the unicorn docs, but not Rainbows!
    (The major difference between unicorn and Rainbows! signal
    handling is the deferred handling of SIGUSR1 in unicorn vs
    the immediate handling in Rainbows!)

    Rainbows! 4.5.0 - hijacking support

    This release adds hijacking support for Rack 1.5.x users.
    See Rack documentation for more information about hijacking.
    Lin Jen-Shin also provided the -N/--no-default-middleware option.
    Minor packaging cleanups and new HACKING document.

    There are also some corner-case bugfixes for *Epoll* users
    (sleepy_penguin, these bugs do not affect EM or Cool.io users)
    and test suite portability improvements.

    epoll/*: remove user-space array as active queue

    This prevents pathological starvation cases where the user-space
    ready-list can be repopulated infinitely.  With EPOLLONESHOT,
    epoll itself may be used for this task (at a slightly higher
    cost) by enabling read/write checks, as the epoll ready-list
    preserves event ordering when used with EPOLLONESHOT.

    hijacking support for Rack 1.5.x users

    support.  Older versions of Rack continue to work fine,

    tests: replace non-portable "date +%s" with ruby equivalent

    "date +%s" is not in POSIX (it is in GNU, and at least FreeBSD
    9.0, possibly earlier).  The Ruby equivalent should be
    sufficiently portable between different Ruby versions.

    This change was automated via:
     perl -i -p -e 's/date \+%s/unix_time/' t/*.sh

    tests: remove utee and use tee(1) instead

    POSIX already stipulates tee(1) must be unbuffered.  I think my
    decision to use utee was due to my being misled by a bug in
    older curl where -N did not work as advertised (but --no-buffer
    did).

    Add -N or --no-default-middleware option.

    This would prevent Unicorn (Rainbows) from adding default middleware,
    as if RACK_ENV were always none. (not development nor deployment)

    This is implemented in Unicorn, so we only need to update
    the option parser here.

    epoll: ensure closing of pipelined clients if required

    on_read normally relies on the close checking in on_readable,
    but on_deferred_write_complete may be called from on_writable
    instead (bypassing the close check of on_readable).

    This affects both Epoll and XEpoll users, but only if they
    were sending responses via body#to_path and triggering
    on_deferred_write_complete.

    While we're at it, favor non-recursive want_more instead of
    calling on_readable recursively in ev_write_responses to
    prevent stack growth.

    Rainbows! 4.4.3 - bugfixes for EventMachine users

    This release fixes two EventMachine bugfixes from Lin Jen-Shin
    and Mark J. Titorenko.  There are also some minor cleanups.

    Lin Jen-Shin (1):
          event_machine: avoid close on deferred response

    Mark J. Titorenko (1):
          event_machine: join reactor_thread if it is already running

     make -C t ThreadPool.t0005-large-file-response.sh

    event_machine: join reactor_thread if it is already running

    ...rather than falling through worker_loop

    Prior to the application of this patch, if an EventMachine
    reactor_thread has already been started elsewhere before the
    worker_loop is entered, the worker_loop exits as a second call
    to EM.run does not block the current thread.

    This patch causes the worker_loop thread to join the
    reactor_thread if it is running.

    fiber_pool: take Fibers from larger pools faster

    Array#pop can be significantly faster than Array#shift on large
    arrays (especially since we push into the Array).  This is
    because Array#shift needs to shift all elements in the array,
    and Array#pop only needs to shorten the array by one element.
    The Fiber stack may also be hotter in CPU caches when we choose
    the most-frequently used stack.

    Rainbows! 4.3.1 - small bugfix

    This release fixes a potential reentrancy deadlock when
    using the default logger from the Ruby standard library.

commit 71b4507755f2bd279adb14e6cdc90e1380efa247
Author: Eric Wong <normalperson@yhbt.net>
Date:   Tue Aug 30 16:18:21 2011 -0700

    avoid potential Logger deadlock in SIGQUIT and SIGUSR1

    If any combination of SIGQUIT and SIGUSR1 are sent to a
    Rainbows! worker in a /very/ short period of time, the Mutex
    used by the default Logger implementation may deadlock since
    Mutex synchronization is not reentrant-safe.

    Users of alternative logger implementations (or monkey-patched
    ones) are possibly not affected.  Users of the logger_mp_safe.rb
    monkey-patch distributed[1] with unicorn are not affected.

    There are only some minor cleanups in this release and a bump to

    Fix Fiber* and WriterThread* breakage from removing io/wait

    This fixes up breakage introduced in commit
    905f0ff393629ddb4d70e3dc221b016128c47415 to switch to
    kgio for timed, synchronous waiting.

    require kgio 2.5 for kgio_wait_readable(timeout)

    Since kgio_wait_*able in kgio 2.5 takes an optional timeout
    argument, we no longer have to load the extra "io/wait" module.
    This saves us a small amount of some memory and also removes the
    extra ioctl(FIONREAD) syscall IO#wait enforces.

    Like IO#wait in Ruby 1.9.3dev, kgio_wait_readable may use
    ppoll() to wait on high-numbered file descriptors as efficiently
    as it waits on low-numbered descriptors.

    Rainbows! 4.0.0 - MOAR concurrency for MOAR COARS

    Rainbows! now scales to more than 1024 worker processes without
    special privileges.  To enable this, Rainbows! now depends on
    Unicorn 4.x and thus raindrops[1].

    client_max_header_size directive is added to limit per-client
    memory usage in headers.

    An experimental StreamResponseEpoll concurrency option now
    exists to buffer outgoing responses without any thread-safe
    dependencies.  Unlike the rest of Rainbows! which works fine
    without nginx, this concurrency option is /only/ supported
    behind nginx, even more strongly so than Unicorn itself.
    non-nginx LAN clients are NOT supported for this.  This relies
    on the sleepy_penguin[2] RubyGem (and Linux).

    There are some minor bug fixes and cleanups all around.  See
    "git log v3.4.0.." for details.

    XEpollThreadPool, XEpollThreadSpawn.

    Kgio.autopush now works properly for all multi-threaded
    concurrency models (if you're using :tcp_nopush).

    xepoll_thread_pool/client: improve autopush support

    We need to trigger a recv() to uncork the response.
    This won't affect fairness (much) since all recv()s
    are non-blocking and a successful header parse will
    put us in the back of the queue.

    Rainbows! 3.3.0 - doc improvements and more

    * improved documentation all around, suggestions/comments to further
      improve documentation is greatly welcome at: rainbows-talk@rubyforge.org

    * added GPLv3 option to the license (now (Ruby|GPLv2|GPLv3), though
      Unicorn is still (Ruby|GPLv2) for now)

    * added client_header_buffer_size config directive (default 1K)

    * small default header buffer size (16K => 1K) to reduce memory usage,
      Rails apps with cookie sessions may want to increase this (~2K)

    * all concurrency models default to 50 connections per process

    * all concurrency models with a secondary :pool_size parameter also
      default to 50 (threads/fibers/whatever)

    * RLIMIT_NOFILE and RLIMIT_NPROC are automatically increased if needed

    * Rainbows::ThreadTimeout middleware rewritten, still not recommended,
      lazy people should be using Unicorn anyways :)

    * Several experimental Linux-only edge-triggered epoll options:
      XEpollThreadSpawn, XEpollThreadPool, XEpoll, and Epoll.
      The latter two were in previous releases but never announced.
      These require the "sleepy_penguin", "raindrops", and "sendfile" RubyGems

    === Deprecations

    * Rainbows::Fiber::IO* APIs all deprecated, Rainbows! will avoid
      having any concurrency model-specific APIs in the future and
      also avoid introducing new APIs for applications.

    * Fiber-based concurrency models are no longer recommended, they're
      too fragile for most apps, use at your own risk (they'll continue to
      be supported, however).  Linux NPTL + Ruby 1.9 is pretty lightweight
      and will be even lighter in Ruby 1.9.3 if you're careful with stack
      usage in your C extensions.

    response_body.each calls which are compatible with all Rack
    servers (to workaround bugs in IO.copy_stream under 1.9.2-p180).

    xepoll: cleanup acceptor logic

    worker_yield is safer than setting a threshold with multiple
    acceptors when thread limits are hit.  Also, avoid sleep +
    Thread#run since it's potentially racy if threads are extremely
    unfairly scheduled.

    Same things applied to xepoll_thread_spawn.

    xepoll_thread_spawn: rework acceptor logic

    Infinite sleep is too dangerous due to possible race conditions,
    so use worker_yield which is safer and cheaper in the general
    case.  We can also avoid sleeping on new threads by only
    spawning when the client module is included.

    Rainbows! 3.2.0 - trying to send files to slow clients

    We now use IO#trysendfile in the sendfile 1.1.0 to reduce the
    cost of generating backtraces for slow clients (from EAGAIN).
    Nothing new for people not serving static files (but more
    on the way).

    Existing "sendfile" gem users must upgrade to 1.1.0
    or risk being left without sendfile support at all:

    switch from IO#sendfile_nonblock to IO#trysendfile

    IO#trysendfile does not raise exceptions for common EAGAIN
    errors, making it far less expensive to use with the following
    concurrency models:

    * Coolio
    * CoolioFiberSpawn
    * Revactor
    * FiberSpawn
    * FiberPool

    This requires the new sendfile 1.1.0 RubyGem and removes support
    for the sendfile 1.0.0.  All sendfile users must upgrade or be
    left without sendfile(2) support.  IO#sendfile behaves the same
    if you're using a multi-threaded concurrency option, but we
    don't detect nor use it unless IO#trysendfile exists.

    Rainbows! 3.1.0 - minor updates

    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 severalnew 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.

    initial XAcceptEpoll concurrency model

    Edge-triggered epoll concurrency model with blocking accept() in
    a (hopefully) native thread.  This is recommended over Epoll for
    Ruby 1.9 users as it can workaround accept()-scalability issues
    on multicore machines.

    Rainbows! 3.0.0 - serving the fastest apps to slow clients faster!

    There is one incompatible change: We no longer assume application
    authors are crazy and use strangely-cased headers for "Content-Length",
    "Transfer-Encoding", and "Range".  This allows us to avoid the
    case-insensitivity of Rack::Utils::HeaderHash for a speed boost on the
    few apps that already serve thousands of requests/second per-worker.

    :Coolio got "async.callback" support like :EventMachine, but it
    currently lacks EM::Deferrables which would allow us to call
    "succeed"/"fail" callbacks.  This means only one-shot response writes
    are supported.

    There are numerous internal code cleanups and several bugfixes for
    handling partial static file responses.

    disable Nagle's algorithm by default

    Nagle's algorithm is harmful with the write-write-read sequence
    during keepalive, so we disable it performance for users using
    keepalive.  We always write headers with a separate write
    because Rack response bodies may not always be ready for writing
    when headers are.

    This requires Unicorn 3.3.0

    a good response.

    416 responses without a body should respond with a zero
    Content-Length and a Content-Range that allows clients
    to specify a proper range in the future.

    rfc2616, section 14.16 says:
    > A server sending a response with status code 416 (Requested
    > range not satisfiable) SHOULD include a Content-Range field
    > with a byte-range- resp-spec of "*". The instance-length
    > specifies the current length of the selected resource.

    Rainbows! 2.1.0 - Cool.io, bugfixes and more!

    Cool.io (new version of Rev) support is explicitly added
    (it always worked before).  ":Coolio" may be used in place
    of ":Rev" anywhere in your Rainbows! config file.

    There is a new "keepalive_requests" config directive to limit
    the number of requests a single connection may make (default:
    100, same as nginx).  This may be useful for better
    load-balancing characteristics.

    The old "Rev" prefixes remain supported as long as Cool.io
    remains compatible with Rev (likely forever).

    Bug fixes:

    * Rainbows::ThreadTimeout middleware with multiple clients
    * large, pipelined upload errors with Revactor+Coolio(Rev)
    * high CPU usage for maintaining idle keepalive on *Fiber*
    * needless ThreadPool wakeups
    * request env prematurely cleared keepalive requests,
      breaking some middlewares such as Clogger.
    * "close" not called on body if wrapper and sendfile used together

    Various code cleanups, and our RDoc website is JavaScript-free.
    See the ChangeLog or git for all changes.

    several response body#close fixes

    Some middlewares require the Rack env to be preserved all
    the way through to close, so we'll ensure all request models
    preserve it.

    We also need to better response body wrappers/proxies always get
    fired properly when returning.  IO.copy_stream and "sendfile"
    gem users could hit cases where wrappers did not fire properly.

    coolio_fiber_spawn: decrease CPU usage for keepalive

    Blindly resuming fibers every second is a waste of cycles, we
    can use the ZZ hash in regular FiberSpawn to resume expired

    heartbeat, there's no reason to have separate timers and
    classes here.

    thread_timeout: avoid a threading bug under 1.9

    Because of the lack of GVL-releasing syscalls in this branch
    of the thread loop, we need Thread.pass to ensure other threads
    get scheduled appropriately under 1.9.  This is likely a threading
    bug in 1.9 that warrants further investigation when we're in a
    better mood.

    Rainbows! 2.0.0 - minority rules!

    This release is targeted at the minority of web applications
    that deal heavily with uploads.

    Thanks to Unicorn 3.x, we now support HTTP keepalive for
    requests with bodies as long as the application consumes them.
    Unicorn 3.x also allows disabling the rewindability requirement
    of "rack.input" (in violation of the Rack 1.x spec).

    The global client_body_max_size may also be applied per-endpoint
    using the Rainbows::MaxBody middleware described in:

      http://rainbows.rubyforge.org/Rainbows/MaxBody.html

    max_body: rewrite wrappers to be safer

    To avoid denial-of-service attacks, the wrappers need to
    intercept requests *before* they hit the memory allocator, so we
    need to reimplement the read(all) and gets cases to use
    smaller buffers whenever the application does not specify one.

    Rack::Lint-compatible input object).

    avoid Errno::EAGAIN, harder

    Errno::EAGAIN is still a problem under Ruby 1.9.2, so try harder
    to avoid it and use kgio methods.  Even when 1.9.3 is available,
    kgio will still be faster as exceptions are slower than normal
    return values.

    Rainbows! 1.0.0 - internal cleanups

    This release is merely a milestone in our evolving internal API.
    Use of kgio may result in performance improvements under Ruby
    1.9.2 with non-blocking I/O-intensive workloads.

    The only bugfix is that SIGHUP reloads restores defaults on
    unset settings.  A similar fix is included in Unicorn 2.0.0
    as well.
