So says the project website and documentation
|
|
Also re-add RubyForge gem upload for now since some folks
may still want to download from there.
|
|

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).
|
|
setsid(8) is non-portable, but we depend on Ruby already and
it's trivial to implement; so just use the Ruby-only version
|
|
Explicitly specify that we mean to use stdin/stdout since
not all tar(1) implementations default to it.
|
|
Generated C code is no longer checked into git so it
doesn't matter.
|
|
Even though we don't RDoc it, our RDoc still links to it.
|
|
Prevent non-umask 0022 shells from generating releases.
Thanks for Jay Reitz for spotting this and reporting
promptly to me; all of my Ruby and gem installations
are done as a regular user so I never would've noticed.

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.

Makes it easier for new projects with no tags yet to reuse
this snippet.
|
|
This lets us run tests out-of-the-box on fresh checkouts and
minimizes the overhead needed for creating/updating the test
installs.
|
|
This should make it easier to test and run unreleased
versions.
|
|
Sometimes we test with unicorn_http.so in lib, but that
gets mistakenly picked up by setup.rb and can wreak havoc
for on upgrades if ABIs change.
|
|
The .manifest dependencies were causing unnecessarily copies for
the tests to run.
|
|
Now tests run after a clean checkout (as long as rack libraries
are in $LOAD_PATH, probably via RUBYLIB).
|
|
No need to bloat our tarballs too much with information people
are unlikely to ever read, NEWS is more user-oriented.
|
|
$(wildcard) is evaluated as soon as the target command
is called, resulting in the manpages not being globbed
since we just generated them. Also, bundle manpages
with documentation.
|
|
I just distributed a tarball with my local FS path
in the documentation :(
|
|
We're expanding our target audience to folks that do not use
HTTP (yet).
|
|
The ChangeLog feed points to the cgit repository viewer
and the NEWS one is its own feed of tags. Web 2.0 here
we come!
|
|
Kinda sorta works, still some Markdown => HTML formatting issues
to work out but it gives the site a reasonably consistent look.
|
|
Additionally, force ourselves to verify our working tree against
$(VERSION) when doing releases because we don't want to screw
that up.
|
|
setup.rb users will now be able to install manpages under
man/man1 automatically, no solution for Rubygems users yet.
gzipped manpages are no longer created by default, either,
it's probably up to distros to do it.

* Manifest/CHANGELOG can be maintainance is painful.
I really hate having those in the source tree when
I have a version control system that already:
1) encourages me to make meaningful commits
2) is highly scriptable for generating manifests/changelogs
* hand-rolled gemspec allows more control for specifying
pre-release gem versions
* Less magic over what the `rubyforge` command does, being
able to spawn $VISUAL on changelogs/release notes and make
edits on them is nice.
Additionally I still strongly prefer GNU make over Rake for many
tasks since it offers better parallelization and some things are
easier *for me* in shell than Ruby.
|
|
No point in having those files under revision control or
repeating work to generate them.
|
|
* Documented Unicorn::HttpParser API methods
* Keep GPL2 (COPYING) as-is without RDoc formatting.
* The auto-generated index.html is stupid, replace it with
README which looks saner.
|

More tightly integrate the C/Ruby portions with C/Ragel to avoid
the confusing the flow. Split out some files into hopefully
logical areas so it's easier to focus on more
interesting/volatile code.
|
|
But keep it in the Manifest
|
|
test/test_helper doesn't seem to be required correctly anymore,
since we know our own module/test names don't conflict, just
fix RUBYLIB to include $(test_prefix)
With test_util.rb, using #reopen with Tempfile objects seems
prone to the objects being closed. Not completely sure what is
going on but I'll just sidestep around it since I've stopped
trusting Tempfile by now...
|
|
We couldn't do proper namespacing for the C module so there was
a potential conflict with Init_http11() in Mongrel. This was
needed because Mongrel's HTTP parser could be used in some
applications and we may be unfortunate enough need to support
them.
|
|
This can allow you to run make with:
TRACER='strace -f -o $(t).strace -s 100000'
to debug a test failure (it should be usable with truss,
ltrace, and other similar tools).
|
|
|
|
Easier to maintain and add new executables this way
|
|
|
|
Installation dependencies weren't being resolved correctly
(since "install-test") wasn't .PHONY. Removed the
"install-test" target entirely since it should never
be invoked by hand.
On the other hand, "ragel" can be useful to invoke by hand
so add a target for that.
|
|
There's no point in having redefinable callbacks if they're
always going to be pointed to the same function. This reduces
the size of the http_parser structure to half its original size.
This change may actually make more sense in servers Mongrel/Thin
than Unicorn since Unicorn only has one parser per-process while
other servers can have hundreds or even thousands.
|
|
It's fast under 1.8, but 1.9 performance is really
terrible, so run the tests in parallel.
|
|
I have a nice hook in git that complains when trailing
whitespace is present.
|
|
|
|
|
|
The $(test_prefix)/.stamp file must be a dependency of the
parent make process otherwise the slow %.n children won't be
able to communicate the dependency up to the other non-slow
tests.
|
|
Run tests with warnings so we detect stupid things like this.
|
|
As usual, spit out all the test output if something fails. But
allow people who like to see things scroll by see things scroll
by. Quiet down the Rails tests by default, too.

It was wrapping in my 80 column terminal when prefixed
with some text.
