A bunch of small fixes related to startup/configuration and hot
reload issues with HUP:
* Variables in the user-generated config.ru files no longer
risk clobbering variables used in laucher scripts.
* signal handlers are initialized before the pid file is
dropped, so over-eager firing of init scripts won't
mysteriously nuke a process.
* SIGHUP will return app to original state if an updated
config.ru fails to load due to {Syntax,Load}Error.
* unicorn_rails should be Rails 3 compatible out-of-the-box
('unicorn' works as always, and is recommended for Rails 3)
* unicorn_rails is finally "working_directory"-aware when
generating default temporary paths and pid file
* config.ru encoding is the application's default in 1.9,
not forced to binary like many parts of Unicorn.
* configurator learned to handle the "user" directive outside
of after_fork hook (which will always remain supported).
There are also various internal cleanups and possible speedups.
This maintenance release is intended for users of Rainbows! and Zbatery servers (and anybody else using Unicorn::HttpParser). This memory leak DID NOT affect Unicorn itself: Unicorn always allocates the HttpParser once and always reuses it in every sequential request. This leak affects applications that repeatedly allocate a new HTTP parser. Thus this bug affects _all_ deployments of Rainbows! and Zbatery. These servers allocate a new parser for every client connection to serve clients concurrently. I misread the Data_Make_Struct()/Data_Wrap_Struct() documentation and ended up passing NULL as the "free" argument instead of -1, causing the memory to never be freed. From README.EXT in the MRI source which I misread: > The free argument is the function to free the pointer > allocation. If this is -1, the pointer will be just freed. > The functions mark and free will be called from garbage > collector.
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!).
The HTTP parser now allows (but does not parse) the userinfo component in the very rare requests that send absoluteURIs. Thanks to Scott Chacon for reporting and submitting a test case for this fix. There are also minor documentation updates and tiny cleanups.
Small fixes to our HTTP parser to allows semicolons in PATH_INFO as allowed by RFC 2396, section 3.3. This is low impact for existing apps as semicolons are rarely seen in URIs. Our HTTP parser runs properly under Rubinius 0.13.0 and 1.0.0-rc1 again (though not yet the rest of the server since we rely heavily on signals). Another round of small documentation tweaks and minor cleanups.
Configuration files paths given on the command-line are no
longer expanded. This should make configuration reloads
possible when a non-absolute path is specified for --config-file
and Unicorn was deployed to a symlink directories (as with
Capistrano). Since deployments have always been strongly
encouraged to use absolute paths in the config file, this
change does not affect them.
This is our first gem release using gemcutter.
Eric Wong (3):
SIGNALS: HUP + preload_app cannot reload app code
Do not expand paths given on the shell
GNUmakefile: prep release process for gemcutter
Mostly internal cleanups and documentation updates. Irrelevant
stacktraces from client disconnects/errors while reading
"rack.input" are now cleared to avoid unnecessary noise. If
user switching in workers is used, ownership of logs is now
preserved when reopening worker logs (send USR1 only to the the
master in this case). The timeout config no longer affects long
after_fork hooks or application startups.
New features include the addition of the :umask option for the
"listen" config directive and error reporting for non-portable
socket options.
No ponies have ever been harmed in our development.

The HTTP parser is fix for oddly-aligned reads of trailers (this
technically affects headers, too, but is highly unlikely due to
our non-support of slow clients). This allows our HTTP parser
to better support very slow clients when used by other servers
(like Rainbows!). Fortunately this bug does not appear to lead
to any invalid memory accesses (and potential arbitrary code
execution).
FreeBSD (and possibly other *BSDs) support is improved and and
all the test cases pass under FreeBSD 7.2. Various flavors of
GNU/Linux remains our primary platform for development and
production.
New features added include the "working_directory" directive in
the configurator . Even without specifying a
"working_directory", symlink-aware detection of the current path
no longer depends on /bin/sh so it should work out-of-the-box on
FreeBSD and Solaris and not just systems where /bin/sh is dash,
ksh93 or bash.
User-switching support is finally supported but only intended
for use in the after_fork hook of worker processes. Putting it
in the after_fork hook allows allows users to set things like
CPU affinity[1] on a per-worker basis before dropping
privileges. The master process retains all privileges it
started with.
The ENV["RACK_ENV"] (process-wide) environment variable is now
both read and set for `unicorn' in the same way RAILS_ENV is
used by `unicorn_rails'. This allows the Merb launcher to read
ENV["RACK_ENV"] in config.ru. Other web servers already set
this and there may be applications or libraries that already
rely on this de facto standard.

Wayne Larsen (1):
bin/unicorn: set ENV["RACK_ENV"] on startup
[1] - Unicorn does not support CPU affinity directly, but it is
possible to load code that allows it inside after_fork hooks,
or even just call sched_tool(8).
This release fixes a regression introduced in 0.93.3 where
timed-out worker processes run a chance of not being killed off
at all if they're hung. While it's not ever advisable to have
requests take a long time, we realize it's easy to fix
everything :)
Eric Wong (3):
TODO: remove --kill
fix reliability of timeout kills
TODO: update for next version (possibly 1.0-pre)
This release mainly works around BSD stdio compatibility issues
that affect at least FreeBSD and OS X. While this issues was
documented and fixed in [ruby-core:26300][1], no production
release of MRI 1.8 has it, and users typically upgrade MRI more
slowly than gems. This issue does NOT affect 1.9 users. Thanks
to Vadim Spivak for reporting and testing this issue and Andrey
Stikheev for the fix.
Additionally there are small documentation bits, one error
handling improvement, and one minor change that should improve
reliability of signal delivery.

unicorn 0.93.3
Avoid truncated POST bodies from with URL-encoded forms in Rails
by switching TeeInput to use read-in-full semantics (only) when
a Content-Length: header exists. Chunked request bodies
continue to exhibit readpartial semantics to support
simultaneous bidirectional chunking.
The lack of return value checking in Rails to protect against a
short ios.read(length) is entirely reasonable even if not
pedantically correct. Most ios.read(length) implementations
return the full amount requested except right before EOF.
Also there are some minor documentation improvements.
Eric Wong (8):

unicorn 0.93.2
Fix permissions for release tarballs/gems, no other changes. Thanks to Jay Reitz for reporting this.
The one minor bugfix is only for Rails 2.3.x+ users who set the
RAILS_RELATIVE_URL_ROOT environment variable in a config file.
Users of the "--path" switch or those who set the environment
variable in the shell were unaffected by this bug. Note that we
still don't have relative URL root support for Rails < 2.3, and
are unlikely to bother with it unless there is visible demand
for it.
New features includes support for :tries and :delay when
specifying a "listen" in an after_fork hook. This was inspired
by Chris Wanstrath's example of binding per-worker listen
sockets in a loop while migrating (or upgrading) Unicorn.
Setting a negative value for :tries means we'll retry the listen
indefinitely until the socket becomes available.
So you can do something like this in an after_fork hook:
after_fork do |server, worker|
addr = "127.0.0.1:#{9293 + worker.nr}"
server.listen(addr, :tries => -1, :delay => 5)
end
There's also the usual round of added documentation, packaging
fixes, code cleanups, small fixes and minor performance
improvements that are viewable in the "git log" output.

unicorn 0.93.0
Small fixes and documentation are the focus of this release.
James Golick reported and helped me track down a bug that caused
SIGHUP to drop the default listener (0.0.0.0:8080) if and only
if listeners were completely unspecified in both the
command-line and Unicorn config file. The Unicorn config file
remains the recommended option for specifying listeners as it
allows fine-tuning of the :backlog, :rcvbuf, :sndbuf,
:tcp_nopush, and :tcp_nodelay options.
There are some documentation (and resulting website)
improvements. setup.rb users will notice the new section 1
manpages for `unicorn` and `unicorn_rails`, Rubygems users
will have to install manpages manually or use the website.
The HTTP parser got a 3rd-party code review which resulted in
some cleanups and one insignificant bugfix as a result.
Additionally, the HTTP parser compiles, runs and passes unit
tests under Rubinius. The pure-Ruby parts still do not work yet
and we currently lack the resources/interest to pursue this
further but help will be gladly accepted.
The website now has an Atom feed for new release announcements.

socket handling bugfixes and usability tweaks
Socket handling bugfixes and socket-related usability and
performance tweaks. We no longer trust FD_CLOEXEC to be
inherited across accept(); thanks to Paul Sponagl for diagnosing
this issue on OSX. There are also minor tweaks backported from
0.9.0 to make non-graceful restarts/upgrades go more smoothly.
Eric Wong (6):

unicorn 0.9.1 (merge 0.8.2)
bodies: "Transfer-Encoding: chunked", rewindable streaming
We now have support for "Transfer-Encoding: chunked" bodies in
requests. Not only that, Rack applications reading input bodies
get that data streamed off to the client socket on an as-needed
basis. This allows the application to do things like upload
progress notification and even tunneling of arbitrary stream
protocols via bidirectional chunked encoding.
See Unicorn::App::Inetd and examples/git.ru (including the
comments) for an example of tunneling the git:// protocol over
HTTP.
This release also gives applications the ability to respond
positively to "Expect: 100-continue" headers before being rerun
without closing the socket connection. See Unicorn::App::Inetd
for an example of how this is used.
This release is NOT recommended for production use.
