2010-10-27doc: stop using deprecated rdoc CLI options
-N and -a switches no longer exist in rdoc 2.5 (cherry picked from commit 054c7df93db61839648925cfd881ae880709a210)
2010-07-11unicorn 1.1.1 - fixing cleanups gone bad :x v1.1.1
Unicorn::TeeInput constant resolution for Unicorn::ClientError got broken simplifying code for RDoc. This affects users of Rainbows! and Zbatery.
2010-06-17unicorn 1.0.0 - yes, this is a real project v1.0.0
There are only minor changes since 0.991.0. For users clinging onto the past, MRI 1.8.6 support has been restored. Users are strongly encouraged to upgrade to the latest 1.8.7, REE or 1.9.1. For users looking towards the future, the core test suite and the Rails 3 (beta) integration tests pass entirely under 1.9.2 preview3. As of the latest rubinius.git[1], Rubinius support is nearly complete as well. Under Rubinius, signals may corrupt responses as they're being written to the socket, but that should be fixable transparently to us[4]. Support for the hardly used, hardly documented[2] embedded command-line switches in rackup config (.ru) files is is also broken under Rubinius. The recently-released Rack 1.2.1 introduced no compatiblity issues[3] in core Unicorn. We remain compatible with all Rack releases starting with 0.9.1 (and possibly before). [1] tested with Rubinius upstream commit cf4a5a759234faa3f7d8a92d68fa89d8c5048f72 [2] lets avoid the Dueling Banjos effect here :x [3] actually, Rack 1.2.1 is broken under 1.8.6.

2010-06-17GNUmakefile: allow RSYNC variable to be overridden
This lets me use RSYNC=echo when testing/editing documentation without actually publishing it.
2010-06-10unicorn 0.991.0 - startup improvements v0.991.0
The "working_directory" configuration parameter is now handled before config.ru. That means "unicorn" and "unicorn_rails" no longer barfs when initially started outside of the configured "working_directory" where a config.ru is required. A huge thanks to Pierre Baillet for catching this ugly UI inconsistency before the big 1.0 release Thanks to Hongli Lai, out-of-the-box Rails 3 (beta) support should be improved for deployments lacking a config.ru There are more new integration tests, cleanups and some documentation improvements.
2010-06-08unicorn 0.990.0 - inching towards 1.0 v0.990.0
Thanks to Augusto Becciu for finding a bug in the HTTP parser that caused a TypeError (and 500) when a rare client set the "Version:" header which conflicts with the HTTP_VERSION header we parse in the first line of the request[1]. Horizontal tabs are now allowed as leading whitespace in header values as according to RFC 2616 as pointed out by IƱaki Baz Castillo[2]. Taking a hint from Rack 1.1, the "logger" configuration parameter no longer requires a "close" method. This means some more Logger replacements may be used. There's a new, optional, Unicorn (and maybe Passenger)-only middleware, Unicorn::OobGC[2] that runs GC outside of the normal request/response cycle to help out memory-hungry applications. Thanks to Luke Melia for being brave enough to test and report back on my big_app_gc.rb monkey patch[3] which lead up to this. Rails 3 (beta) support: Using "unicorn" is still recommended as Rails 3 comes with a config.ru, but "unicorn_rails" is cleaned up a bit and *should* work as well as "unicorn" out-of-the-box. Feedback is much appreciated. Rubinius updates: USR2 binary upgrades are broken due to {TCPServer,UNIXServer}.for_fd[5][6] being broken (differently). Repeatedly hitting the server with signals in a tight loop is unusual and not recommended[7]. There are some workarounds and general code cleanups for other issues[8], as well but things should generally work unless you need USR2 upgrades. Feedback and reports would be greatly appreciated as usual. MRI support: All tests (except old Rails) run and pass under 1.9.2-preview3. 1.8.7 and 1.9.1 work well as usual and will continue to be supported indefinitely. Lets hope this is the last release before 1.0. Please report any issues on the mailing list[9] or email us privately[a]. Don't send HTML mail.

2010-06-08cleanup makefiles, restore aggregation screwup
The publish_doc target belongs in main, since other people may update the website. local.mk.sample enables a subset of tests for Rubinius and allows them to run in parallel with the MRI tests. And it was NOT a UUoC after all, there are multiple files to aggregate :x
2010-06-08GNUmakefile: add test-all and test-integration targets
Long overdue
2010-06-08update test infrastructure to run Rubinius tests
In parallel with other of Rubies, of course. We need to rely on RUBY_ENGINE since RUBY_VERSION is 1.8.7 and that conflicts with the most popular MRI version. Since Rubinius doesn't support some command-line options, we still need to rely on MRI for a few things. Also fixing an embarrassing UUoC in the process.
2010-06-03move Rails 2.3.x test to Rails 2.3.8
This allows us to gets rid of the Rack 1.0.1 dependency when running Rails tests since previous versions of Rails 2.3.x needed Rack 1.0.1, where as Rails 2.2.x and below could be used with any version of Rack (under Unicorn only).
2010-05-06GNUmakefile: update RAA and Freshmeat on release
2010-05-04unicorn 0.98.0 v0.98.0
Deployments that suspend or hibernate servers should no longer have workers killed off (and restarted) upon resuming. For Linux users of {raindrops}[http://raindrops.bogomips.org/] (v0.2.0+) configuration is easier as raindrops can now automatically detect the active listeners on the server via the new Unicorn.listener_names singleton method. For the pedantic, chunked request bodies without trailers are no longer allowed to omit the final CRLF. This shouldn't affect any real and RFC-compliant clients out there. Chunked requests with trailers have always worked and continue to work the same way. The rest are mostly small internal cleanups and documentation fixes. See the commit logs for full details.
2010-04-26GNUmakefile: fix backwards compat links for manpages
2010-04-26GNUmakefile: rdoc 2.5.x compatibility
2010-04-26GNUmakefile: avoid FS namespace conflict
'tmp' may be a directory when using rake-compiler (or isolate), so avoid naming a file 'tmp'
2010-03-01unicorn 0.97.0 - polishing and cleaning up v0.97.0
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.
2010-02-17tests: import basic TAP library from Rainbows!
2010-02-17GNUmakefile: remove old, lower-case variables
We started using upper-case variables a while back, so just remove the backwards-compatibility clutter.
2010-01-07unicorn 0.96.0 - Rack 1.1 bump v0.96.0
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!).
2010-01-05NEWS: generation depends on .manifest
2009-12-21build: favor upper-case variable names in Makefiles
It should be more compatible and easier to express that they're overridable to hackers. We keep the lower-case versions around in case people depend on them.

2009-11-15unicorn 0.95.0 v0.95.0
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. Eric Wong (28): unicorn.1: document RACK_ENV changes in 0.94.0 HACKING: update with "gmake" in examples don't nuke children for long after_fork and app loads local.mk.sample: steal some updates from Rainbows!

2009-11-05unicorn 0.94.0 v0.94.0
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 configurator: working_directory affects pid, std{err,out}_paths configurator: update documentation for working_directory TODO: remove working_directory bit, done Util.reopen_logs: remove needless Range worker: user/group switching for after_fork hooks Fix autoload of Etc in Worker for Ruby 1.9 bin/unicorn: allow RACK_ENV to be passed from parent tests for RACK_ENV preservation http: allow headers/trailers to be written byte-wise http: extra test for bytewise chunked bodies tee_input: do not clobber trailer buffer on partial uploads test_exec: ensure master is killed after test Util::tmpio returns a TmpIO that responds to #size TODO: remove user-switching bit, done unicorn 0.94.0 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).
2009-10-30tests: provide a pure Ruby setsid(8) equivalent
setsid(8) is non-portable, but we depend on Ruby already and it's trivial to implement; so just use the Ruby-only version
2009-10-30GNUmakefile: fix non-portable tar(1) usage
Explicitly specify that we mean to use stdin/stdout since not all tar(1) implementations default to it.
2009-10-09drop the whitespace cleaner for Ragel->C
Generated C code is no longer checked into git so it doesn't matter.
2009-10-05Include GPLv2 in docs
Even though we don't RDoc it, our RDoc still links to it.
2009-10-02verify liberal file permissions when packaging
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.
2009-10-02unicorn 0.93.0 v0.93.0
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.

2009-10-02tests: GIT-VERSION-GEN is a test install dependency
2009-10-02GNUmakefile: SINCE variable may be unset
Makes it easier for new projects with no tags yet to reuse this snippet.
2009-10-02test: don't rely on .manifest for test install
This lets us run tests out-of-the-box on fresh checkouts and minimizes the overhead needed for creating/updating the test installs.
2009-09-30Add makefile targets for non-release installs
This should make it easier to test and run unreleased versions.
2009-09-27"make install" avoids installing multiple .so objects
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.
2009-09-27GNUmakefile: cleanup test/manifest generation
The .manifest dependencies were causing unnecessarily copies for the tests to run.
2009-09-18GNUmakefile: add missing .manifest dep on test installs
Now tests run after a clean checkout (as long as rack libraries are in $LOAD_PATH, probably via RUBYLIB).
2009-09-18build: smaller ChangeLog
No need to bloat our tarballs too much with information people are unlikely to ever read, NEWS is more user-oriented.
2009-09-18build: manifest dropped manpages
$(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.
2009-09-18build: hardcode the canonical git URL
I just distributed a tarball with my local FS path in the documentation :(
2009-09-18doc: latest news is available through finger
We're expanding our target audience to folks that do not use HTTP (yet).
2009-09-18html: add Atom feeds
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!
2009-09-17doc: begin integration of HTML manpages into RDoc
Kinda sorta works, still some Markdown => HTML formatting issues to work out but it gives the site a reasonably consistent look.
2009-09-17GNUmakefile: package .tgz includes all generated files
Additionally, force ourselves to verify our working tree against $(VERSION) when doing releases because we don't want to screw that up.
2009-09-17Simplify and standardize manpages build/install
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.
