Changes:
unicorn 5.3.0
A couple of portability fixes from Dylan Thacker-Smith and
Jeremy Evans since 5.3.0.pre1 over a week ago, but this looks
ready for a stable release, today.
When I started this over 8 years ago, I wondered if this would
just end up being an April Fools' joke. Guess not. I guess I
somehow tricked people into using a terribly marketed web server
that cannot talk directly to untrusted clients :x Anyways,
unicorn won't be able to handle slow clients 8 years from now,
either, or 80 years from now. And I vow never to learn to use
new-fangled things like epoll, kqueue, or threads :P
Anyways, this is a largish release with several new features,
and no backwards incompatibilities.
Simon Eskildsen contributed heavily using TCP_INFO under Linux
to implement the (now 5 year old) check_client_connection feature:
https://bogomips.org/unicorn/Unicorn/Configurator.html#method-i-check_client_connection
https://bogomips.org/unicorn-public/?q=s:check_client_connection&d:..20170401&x=t
This also led to FreeBSD and OpenBSD portability improvements in
one of our dependencies, raindrops:
https://bogomips.org/raindrops-public/20170323024829.GA5190@dcvr/T/#u
Jeremy Evans contributed several new features. First he
implemented after_worker_exit to aid debugging:
https://bogomips.org/unicorn/Unicorn/Configurator.html#method-i-after_worker_exit
https://bogomips.org/unicorn-public/?q=s:after_worker_exit&d:..20170401&x=t#t
And then security-related features to isolate workers. Workers
may now chroot to drop access to the master filesystem, and the
new after_worker_ready configuration hook now exists to aid with
chroot support in workers:
https://bogomips.org/unicorn/Unicorn/Configurator.html#method-i-after_worker_ready
https://bogomips.org/unicorn/Unicorn/Worker.html#method-i-user
https://bogomips.org/unicorn-public/?q=s:after_worker_ready&d:..20170401&x=t#t
https://bogomips.org/unicorn-public/?q=s:chroot&d:..20170401&x=t#t
Additionally, workers may run in a completely different VM space
(nullifying preload_app and any CoW savings) with the new
worker_exec option:
https://bogomips.org/unicorn/Unicorn/Configurator.html#method-i-worker_exec
https://bogomips.org/unicorn-public/?q=s:worker_exec&d:..20170401&x=t#t
There are also several improvements to FreeBSD and OpenBSD
support with the addition of these features.

rack 2.x exists nowadays still allows rewindable input as an
option, and we will still enable it by default to avoid breaking
any existing code.
Hide the internal documentation since we do not want people
depending on unicorn internals; so there's no reason to confuse
or overwhelm people with documentation about it. Arguably,
TeeInput and StreamInput should not be documented publically at
all, but I guess that ship has long sailed...

Thanks, I'll queue up something like the following patch.
Comments/corrections greatly appreciated:
------------------------------8<-------------------------------
From: Eric Wong <normalperson@yhbt.net>
Subject: [PATCH] doc: update documentation for systemd + PrivateTmp users
The PrivateTmp feature of systemd breaks the usage of /tmp for the
shared Unix domain socket between nginx and unicorn, so discourage the
use of /tmp in that case.
While we're at it, use consistent paths for everything and use an
obviously intended-for-user-customization "/path/to" prefix instead
of "/tmp"

Hi all,
Since some folks have been running Unicorn in production for a while,
we might as well call the next release 1.0.
I have a couple of minor fixes in unicorn.git on top of 0.991.0.
Mainly, there are small compatibility fixes for the future (MRI 1.9.2
and Rubinius) and the past (MRI 1.8.6(!)).
There are also some documentation updates for Rack 1.2, but we should be
compatible with everything from Rack 0.9 (possibly earlier) to the
latest Rack 1.2.
Shortlog since 0.991.0:
Eric Wong (8):
doc: cleanup rdoc escaping in title, hopefully
cleanup: use modules were applicable
t0005: Ruby 1.9.2 $LOAD_PATH fix
http: fix rb_str_set_len() define for 1.8.6
app/exec_cgi: rack.input may not respond to #size
local.mk.sample: add 1.8.6-p114 to "full-test"
tee_input: update documentation for Rack 1.2
FAQ: help folks help themselves for processes dying in a loop
Let us know if there's anything else missing, pipe up within the next 24
hours or so...
You can always email me privately if you don't want your address on the
public mailing list. Don't send HTML mail, though.

Unicorn is a 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:
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.
Eric Wong (26):
cleanup: avoid redundant error checks for fstat
test_helper: connect(2) may fail with EINVAL
GNUmakefile: fix non-portable tar(1) usage
tests: provide a pure Ruby setsid(8) equivalent
more portable symlink awareness for START_CTX[:cwd]
test_signals: avoid portability issues with fchmod(2)
cleanup error handling and make it less noisy
Do not override Dir.chdir in config files
configurator: add "working_directory" directive
configurator: working_directory is expanded
configurator: set ENV["PWD"] with working_directory, too

possible to load code that allows it inside after_fork hooks,
or even just call sched_tool(8).

Unicorn is a Rack HTTP server for Unix and fast clients
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.
Edit: That's not entirely true, I screwed up the package but
you can get them from http://unicorn.bogomips.org/unicorn.1
and http://unicorn.bogomips.org/unicorn_rails.1
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.
Those unfamiliar with Atom or HTTP may finger unicorn@bogomips.org
for the latest announcements.

* HTTP parser C extension should be Rubinius-compatible

Hi all,
I've just pushed out some changes to the C HTTP parser that should make
it compatible with a recent Rubinius[1] using the C API. While I got
the http_parser and http_parser_ng tests to pass with the new changes,
most of the other tests that use pure Ruby actually failed(!).
If anybody wants to pick up where I left off (even if it's to properly
report bugs to the Rubinius team), please do so. I'm not quite
motivated enough to do much more myself for a variety of reasons:
1) non-(CLI|email) bug trackers scare me
2) IRC kills my concentration
3) BDD specs are weird to me[2]
4) lack of folks in need of Rubinius support *right* *now*
I'm sure if more things start using/working-with Rubinius I'd be more
inclined to do more, but right now we're stuck in a Catch-22...
Shortlog of relevant changes pushed out to
git://git.bogomips.org/unicorn tonight:
Eric Wong (6):
http: define OFFT2NUM macro on Rubies without it
http: no-op rb_str_modify() for Rubies without it
http: compile with -fPIC
http: use rb_str_{update,flush} if available
http: create a new string buffer on empty values
Update documentation for Rubinius support status
[1] tested with db612aa62cad9e5cc41a4a4be645642362029d20
[2] to be fair, Unicorn using gmake to parallelize test/unit
is weird to the rest of the world, too
