unicorn 4.2.0
The GPLv3 is now an option to the Unicorn license. The existing GPLv2
and Ruby-only terms will always remain options, but the GPLv3 is
preferred.
Daemonization is correctly detected on all terminals for development
use (Brian P O'Rourke).
Unicorn::OobGC respects applications that disable GC entirely
during application dispatch (Yuichi Tateno).
Many test fixes for OpenBSD, which may help other *BSDs, too.
(Jeremy Evans).
There is now _optional_ SSL support (via the "kgio-monkey"
RubyGem). On fast, secure LANs, SSL is only intended for
detecting data corruption that weak TCP checksums cannot detect.
Our SSL support is remains unaudited by security experts.
There are also some minor bugfixes and documentation
improvements.
Ruby 2.0.0dev also has a copy-on-write friendly GC which can save memory
when combined with "preload_app true", so if you're in the mood, start
testing Unicorn with the latest Ruby!

quiet possible IOError from SIGUSR1 (reopen logs)
It's possible for a SIGUSR1 signal to be received in the
worker immediately before calling IO.select. In that case,
do not clutter logging with IOError and just process the
reopen log request.

socket_helper: set SO_KEEPALIVE on TCP sockets
Even LANs can break or be unreliable sometimes and socket
disconnect messages get lost, which means we fall back to
the global (kill -9) timeout in Unicorn.
While the default global timeout is much shorter (60s) than
typical TCP timeouts, some HTTP application dispatches take much
I/O or computational time (streaming many gigabytes), so the
global timeout becomes ineffective.
Under Linux, sysadmins are encouraged to lower the default
net.ipv4.tcp_keepalive_* knobs in sysctl. There should be
similar knobs in other operating systems (the default keepalive
intervals are usually ridiculously high, too high for anything).
When the listen socket has SO_KEEPALIVE set, the flag should be
inherited by accept()-ed sockets.

tests: just use the sha1sum implemented in Ruby
The output of SHA1 command-line tools is too unstable and
I'm more comfortable with Ruby 1.9 encoding support than
I was in 2009.
Jeremy Evans noted the output of "openssl sha1" has
changed since I last used it.

configurator: limit timeout to 30 days
There's no practical difference between a timeout of 30 days and
68 years from an HTTP server standpoint.
POSIX limits us to 31 days, actually, but there could be
rounding error with floats used in Ruby time calculations and
there's no real difference between 30 and 31 days, either...
Thanks to Jeremy Evans for pointing out large values will throw
EINVAL (on select(2) under OpenBSD with Ruby 1.9.3 and
RangeError on older Rubies.

This will also be the foundation of SSL support in Rainbows!

Unicorn on LANs to meet certain security/auditing requirements.
Of course, Nightmare! (in whatever form) should also be able to
use it.

Links: add a link to the UnXF middleware
Since unicorn is designed to be deployed behind nginx (or
similar), X-Forwarded-* headers are common and Rack applications
may blindly trust spoofed X-Forwarded-* headers. UnXF provides
a central place for managing that trust by using rpatricia.

unicorn 4.1.1 - fix last-resort timeout accuracy
The last-resort timeout mechanism was inaccurate and often
delayed in activation since the 2.0.0 release. It is now fixed
and remains power-efficient in idle situations, especially with
the wakeup reduction in MRI 1.9.3+.
There is also a new document on application timeouts
intended to discourage the reliance on this last-resort
mechanism. It is visible on the web at:

unicorn 4.1.0 - small updates and fixes
* Rack::Chunked and Rack::ContentLength middlewares are loaded
by default for RACK_ENV=(development|deployment) users to match
Rack::Server behavior. As before, use RACK_ENV=none if you want
fine-grained control of your middleware. This should also
help users of Rainbows! and Zbatery.
* CTL characters are now rejected from HTTP header values
* Exception messages are now filtered for [:cntrl:] characters
since application/middleware authors may forget to do so
* Workers will now terminate properly if a SIGQUIT/SIGTERM/SIGINT
is received while during worker process initialization.
* close-on-exec is explicitly disabled to future-proof against
Ruby 2.0 changes [ruby-core:38140]

Rack::Chunked and ContentLength middlewares by default
This is needed to match the behavior of Rack::Server for
RACK_ENV=(deployment|development), actually. This won't
affect users of other RACK_ENV values.
This change has minor performance consequences, so users
negatively affected should set RACK_ENV to "none" instead for
full control of their middleware stack.
This mainly affects Rainbows!/Zbatery users since they have
persistent connections and /need/ Content-Length or
Transfer-Encoding:chunked headers.

future-proof against close-on-exec by default
Setting the close-on-exec flag by default and closing
non-standard descriptors is proposed for Ruby 1.9.4/2.0.0.
Since Unicorn is one of the few apps to rely on FD inheritance
across exec(), we need to workaround this by redirecting each
listener FD to itself for Kernel#exec.
Ruby supports a hash as the final argument to Kernel#exec since
at least 1.9.1 (nobody cares for 1.9.0 anymore). This allows
users to backport close-on-exec by default patches to older
1.9.x installs without breaking anything.

RFC 2616 doesn't appear to allow most CTL bytes even though

allow "\t" (HT, 09) since it's LWS and allowed by RFC 2616.

unicorn 4.0.0 - for mythical hardware!
A single Unicorn instance may manage more than 1024 workers
without needing privileges to modify resource limits. As a
result of this, the "raindrops"[1] gem/library is now a required
dependency.
TCP socket defaults now favor low latency to mimic UNIX domain
socket behavior (tcp_nodelay: true, tcp_nopush: false). This
hurts throughput, users who want to favor throughput should
specify "tcp_nodelay: false, tcp_nopush: true" in the listen
directive.
Error logging is more consistent and all lines should be
formatted correctly in backtraces. This may break the
behavior of some log parsers.
The call stack is smaller and thus easier to examine backtraces
when debugging Rack applications.
There are some internal API changes and cleanups, but none that
affect applications designed for Rack. See "git log v3.7.0.."
for details.
For users who cannot install kgio[2] or raindrops, Unicorn 1.1.x
remains supported indefinitely. Unicorn 3.x will remain
supported if there is demand. We expect raindrops to introduce
fewer portability problems than kgio did, however.

spawned processes, but at least we avoid the extra overhead of
creating an array every time.

reenable heartbeat checking for idle workers
Some applications/libraries may launch background threads which
can lock up the process. So we can't disable heartbeat checking
just because the main thread is sleeping. This also has the
side effect of reducing master process wakeups when all workers
are idle.

http_server: avoid race conditions on SIGQUIT
We don't want the Worker#tick= assignment to trigger after we
accept a client, since we'd drop that request when we raise the
exception that breaks us out of the worker loop.
Also, we don't want to enter IO.select with an empty LISTENERS
array so we can fail with IOError or Errno::EBADF.

error logging is more consistent
Backtraces are now formatted properly (with timestamps) and
exceptions will be logged more consistently and similar to
Logger defaults:
"#{exc.message} (#{e.class})"
backtrace.each { |line| ... }
This may break some existing monitoring scripts, but errors
will be more standardized and easier to check moving forward.

unicorn 3.6.2 - fix Unicorn::OobGC module
The optional Unicorn::OobGC module is reimplemented to fix
breakage that appeared in v3.3.1. There are also minor
documentation updates, but no code changes as of 3.6.1 for
non-OobGC users.
There is also a v1.1.7 release to fix the same OobGC breakage
that appeared for 1.1.x users in the v1.1.6 release.

unicorn 1.1.7 - major fixes to minor components
No changes to the core code, so this release only affects users
of the Unicorn::OobGC and Unicorn::ExecCGI modules.
Unicorn::OobGC was totally broken by the fix in the v1.1.6
release and is now reimplemented. Unicorn::ExecCGI (which
hardly anybody uses) now returns proper HTTP status codes.

oob_gc: reimplement to fix breakage and add tests
This was broken since v3.3.1[1] and v1.1.6[2] since nginx relies on
a closed socket (and not Content-Length/Transfer-Encoding) to
detect a response completion. We have to close the client
socket before invoking GC to ensure the client sees the response
in a timely manner.

oob_gc: reimplement to fix breakage and add tests
This was broken since v3.3.1[1] since nginx relies on a closed
socket (and not Content-Length/Transfer-Encoding) to detect
a response completion. We have to close the client socket
before invoking GC to ensure the client sees the response
in a timely manner.

configurator: attempt to clarify :tcp_nopush/:tcp_nodelay
These options will probably be more important as interest in
streaming responses in Rails 3.1 develops.
I consider the respective defaults for Unicorn (designed to run
behind nginx) and Rainbows! (designed to run standalone) to be
the best choices in their respective environments.

examples/nginx.conf: clarify proxy_buffering for Rails 3.1
I've tested with nginx 1.0.0 and confirmed "proxy_buffering off;"
can cause Unicorn to block on a slow client reading a
large response. While there's a potential (client-visible)
performance improvement with Rails 3.1 streaming responses, it
can also hurt the server with slow clients.
Rainbows! with (ThreadSpawn or ThreadPool) is probably the best
way to do streaming responses efficiently from all angles (from
a server, client and programmer time perspective).

unicorn 3.6.1 - fix OpenSSL PRNG workaround
Our attempt in 3.6.0 to workaround a problem with the OpenSSL
PRNG actually made the problem worse. This release corrects the
workaround to properly reseed the OpenSSL PRNG after forking.

properly reseed OpenSSL::Random after forking
Using the return value of Kernel#srand actually made the
problem worse. Using the value of Kernel#rand is required
to actually get a random value to seed the OpenSSL PRNG.

unicorn 3.6.0 - small fixes, PRNG workarounds
Mainly small fixes, improvements, and workarounds for fork() issues
with pseudo-random number generators shipped with Ruby (Kernel#rand,
OpenSSL::Random (used by SecureRandom and also by Rails).
The PRNG issues are documented in depth here (and links to Ruby Redmine):
http://bogomips.org/unicorn.git/commit?id=1107ede7
http://bogomips.org/unicorn.git/commit?id=b3241621
If you're too lazy to upgrade, you can just do this in your after_fork
hooks:
after_fork do |server,worker|
tmp = srand
OpenSSL::Random.seed(tmp.to_s) if defined?(OpenSSL::Random)
end
There are also small log reopening (SIGUSR1) improvements:
* relative paths may also be reopened, there's a small chance this
will break with a handful of setups, but unlikely. This should
make configuration easier especially since the "working_directory"
configurator directive exists. Brought up by Matthew Kocher:
http://thread.gmane.org/gmane.comp.lang.ruby.unicorn.general/900
* workers will just die (and restart) if log reopening fails for
any reason (including user error). This is to workaround the issue
reported by Emmanuel Gomez:

reseed OpenSSL PRNG upon fork() of workers
OpenSSL seeds its PRNG with the process ID, so if a process ID
is recycled, there's a chance of indepedent workers getting
repeated PRNG sequences over a long time period iff the same
PID is used.
This only affects deployments that meet both of the following
conditions:
1) OpenSSL::Random.random_bytes is called before forking
2) worker (but not master) processes are die unexpectedly
The SecureRandom module in Ruby (and Rails) uses the OpenSSL
PRNG if available. SecureRandom is used by Rails and called
when the application is loaded, so most Rails apps with
frequently dying worker processes are affected.
Of course dying worker processes are bad and entirely the
fault of bad application/library code, not the fault of
Unicorn.
Thanks for Alexander Dymo for reporting this.

unicorn 3.4.0 - for people with very big LANs
* IPv6 support in the HTTP hostname parser and configuration
language. Configurator syntax for "listen" addresses should
be the same as nginx. Even though we support IPv6, we will
never support non-LAN/localhost clients connecting to Unicorn.
* TCP_NOPUSH/TCP_CORK is enabled by default to optimize
for bandwidth usage and avoid unnecessary wakeups in nginx.
* Updated KNOWN_ISSUES document for bugs in recent Ruby 1.8.7
(RNG needs reset after fork) and nginx+sendfile()+FreeBSD 8.
* examples/nginx.conf updated for modern stable versions of nginx.
* "Status" in headers no longer ignored in the response,
Rack::Lint already enforces this so we don't duplicate
the work.
* All tests pass under Ruby 1.9.3dev
* various bugfixes in the (mostly unused) ExecCGI class that
powers http://bogomips.org/unicorn.git

nginx proxy server if nginx is over TCP. Mongrel 1.x had
TCP_CORK enabled by default, too.

http_response: implement httpdate in C
This can return a static string and be significantly
faster as it reduces object allocations and Ruby method
calls for the fastest websites that serve thousands of

It assumes the Ruby runtime is single-threaded, but that
is the case of Ruby 1.8 and 1.9 and also what Unicorn
is all about. This change is safe for Rainbows! under 1.8
and 1.9.

one to be valid.
Additionally, respect X-Forwarded-SSL as it may be passed with

http: support keepalive_requests directive
This limits the number of keepalive requests of a single
connection to prevent a single client from monopolizing server
resources. On multi-process servers (e.g. Rainbows!) with many
keepalive clients per worker process, this can force a client to
reconnect and increase its chances of being accepted on a
less-busy worker process.
This directive is named after the nginx directive which
is identical in function.

patterns and Configurator examples in the FAQ should be fixed

In case a request sends the header and buffer as one packet,
TeeInput relying on accounting info from StreamInput is harmful

env["rack.input"].rewind before to read.

unicorn 3.0.0 - disable rewindable input!
Rewindable "rack.input" may be disabled via the
"rewindable_input false" directive in the configuration file.
This will violate Rack::Lint for Rack 1.x applications, but can
reduce I/O for applications that do not need a rewindable
input.
This release updates us to the Kgio 2.x series which should play
more nicely with other libraries and applications. There are
also internal cleanups and improvements for future versions of
Rainbows!
The Unicorn 3.x series supercedes the 2.x series
while the 1.x series will remain supported indefinitely.

unicorn 3.0.0pre1
Rewindable "rack.input" may be disabled via the
"rewindable_input false" directive in the configuration file.
This will violate Rack::Lint for Rack 1.x applications, but
can reduce I/O for applications that do not need it.
There are also internal cleanups and enhancements for future
versions of Rainbows!

preread_input: no-op for non-rewindable "rack.input"
We may get "rack.input" objects that are not rewindable
in the future, so be prepared for those and do no harm.

tee_input: restore read position after #size
It's possible for an application to call size after it has read
a few bytes/lines, so do not screw up a user's read offset when
consuming input.

*_input: make life easier for subclasses/modules
Avoid having specific knowledge of internals in TeeInput
and instead move that to StreamInput when dealing with
byte counts. This makes things easier for Rainbows! which
will need to extends these classes.

configurator: enable "rewindable_input" directive
This allows users to override the current Rack spec and disable
the rewindable input requirement. This can allow applications
to use less I/O to minimize the performance impact when
processing uploads.

add stream_input class and build tee_input on it
We will eventually expose a Unicorn::StreamInput object as
"rack.input" for Rack 2.x applications. StreamInput allows
applications to avoid buffering input to disk, removing the
(potentially expensive) rewindability requirement of Rack 1.x.
TeeInput is also rewritten to build off StreamInput for
simplicity. The only regression is that TeeInput#rewind forces
us to consume an unconsumed stream before returning, a
negligible price to pay for decreased complexity.

unicorn 2.0.0 - mostly internal cleanups
Despite the version number, this release mostly features
internal cleanups for future versions of Rainbows!. User
visible changes include reductions in CPU wakeups on idle sites
using high timeouts.
Barring possible portability issues due to the introduction of
the kgio library, this release should be ready for all to use.
However, 1.1.x (and possibly 1.0.x) will continue to be
maintained. Unicorn 1.1.5 and 1.0.2 have also been released
with bugfixes found during development of 2.0.0.

configurator: reloading with unset values restores default
If a configuration directive is set at startup and later
unset, it correctly restores the original default value
as if it had never been set in the first place.
This applies to the majority of the configuration values with
a few exceptions:
* This only applies to stderr_path and stdout_path when
daemonized (the usual case, they'll be redirected to
"/dev/null"). When NOT daemonized, we cannot easily redirect
back to the original stdout/stderr destinations.
* Unsetting working_directory does not restore the
original working directory where Unicorn was started.
As far as we can tell unsetting this after setting it is
rarely desirable and greatly increases the probability of
user error.

master: remove limit on queued signals
If a moronic sysadmin is sending too many signals, just let them
do it. It's likely something is terribly wrong when the server
is overloaded with signals, so don't try to protect users from
it. This will also help in case where TTOU signals are sent too
quickly during shutdown, although sleeping between kill(2)
syscalls is always a good idea because of how non-real-time
signals are delivered.

unicorn 2.0.0pre3 - more small fixes
There is a new Unicorn::PrereadInput middleware to which allows
input bodies to be drained off the socket and buffered to disk
(or memory) before dispatching the application.
HTTP Pipelining behavior is fixed for Rainbows! There
are some small Kgio fixes and updates for Rainbows!
users as well.

accessor methods) are also slightly faster, so use them in
the criticial process_client code path.

http_response: avoid singleton method
There's no need for a response class or object since Rack just
uses an array as the response. So use a procedural style which
allows for easier understanding.
We shall also support keepalive/pipelining in the future, too.

avoid unlinking actively listening sockets
While we've always unlinked dead sockets from nuked/leftover
processes, blindly unlinking them can cause unnecessary failures
when an active process is already listening on them. We now
make a simple connect(2) check to ensure the socket is not in
use before unlinking it.
Thanks to Jordan Ritter for the detailed bug report leading to
this fix.

IOError may occur due to race conditions as another thread

to check.
Errno::EBADF may occur in some applications that close a file
descriptor without notifying Ruby (or if two IO objects refer to
the same descriptor, possibly one of them using IO#for_fd).

SIGHUP deals w/ dual master pid path scenario
As described in our SIGNALS documentation, sending SIGHUP to the
old master (to respawn SIGWINCH-ed children) while the new
master (spawned from SIGUSR2) is active is useful for backing
out of an upgrade before sending SIGQUIT to the new master.
Unfortunately, the SIGHUP signal to the old master will cause
the ".oldbin" pid file to be reset to the non-".oldbin" version
and thus attempt to clobber the pid file in use by the
to-be-terminated new master process.
Thanks to the previous commit to prevent redaemonization in the
new master, the old master can reliably detect if the new master
is active while it is reloading the config file.
Thanks to Lawrence Pit for discovering this bug.

launcher: do not re-daemonize when USR2 upgrading
This was accidentally enabled when ready_pipe was developed.
While re-daemonizing appears harmless in most cases this makes
detecting backed-out upgrades from the original master process
impossible.

tee_input: safer record separator ($/) handling
Different threads may change $/ during execution, so cache it at
function entry to a local variable for safety. $/ may also be
of a non-binary encoding, so rely on Rack::Utils.bytesize to
portably capture the correct size.
Our string slicing is always safe from 1.9 encoding: both our
socket and backing temporary file are opened in binary mode,
so we'll always be dealing with binary strings in this class
(in accordance to the Rack spec).

socket_helper: tunables for tcp_defer_accept/accept_filter
Under Linux, this allows users to tune the time (in seconds) to
defer connections before allowing them to be accepted. The
behavior of TCP_DEFER_ACCEPT changed with Linux 2.6.32 and idle
connections may still be accept()-ed after the specified value
in seconds. A small value of '1' remains the default for
Unicorn as Unicorn does not worry about slow clients. Higher
values provide better DoS protection for Rainbows! but also
increases kernel memory usage.
Allowing "dataready" for FreeBSD accept filters will allow
SSL sockets to be used in the future for HTTPS, too.
