=== 3.0.1 / 2010-12-03 00:34 UTC ...and only Rainbows! This release fixes HTTP pipelining for requests with bodies for users of synchronous Rainbows! concurrency models. Since Unicorn itself does not support keepalive nor pipelining, Unicorn-only users need not upgrade. === 3.0.0 / 2010-11-20 02:41 UTC 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. === 3.0.0pre2 / 2010-11-19 00:07 UTC This release updates us to the Kgio 2.x series which should play more nicely with other applications. There are also bugfixes from the 2.0.1 release and a small bugfix to the new StreamInput class. The Unicorn 3.x series will supercede the 2.x series while the 1.x series will remain supported indefinitely. === 2.0.1 / 2010-11-17 23:48 UTC This release fixes errors in our own error handling, causing certain errors to not be logged nor responded to correctly. Eric Wong (3): t0012: fix race condition in reload http_server: fix HttpParserError constant resolution tests: add parser error test from Rainbows! === 3.0.0pre1 / 2010-11-17 00:04 UTC 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! Eric Wong (11): t0012: fix race condition in reload enable HTTP keepalive support for all methods http_parser: add HttpParser#next? method tee_input: switch to simpler API for parsing trailers switch versions to 3.0.0pre add stream_input class and build tee_input on it configurator: enable "rewindable_input" directive http_parser: ensure keepalive is disabled when reset *_input: make life easier for subclasses/modules tee_input: restore read position after #size preread_input: no-op for non-rewindable "rack.input" === 2.0.0 / 2010-10-27 23:44 UTC 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. === 1.1.5 / 2010-10-27 23:30 UTC This maintenance release fixes several long-standing but recently-noticed bugs. SIGHUP reloading now correctly restores default values if they're erased or commented-out in the Unicorn configuration file. Delays/slowdowns in signal handling since 0.990 are fixed, too. === 1.0.2 / 2010-10-27 23:12 UTC This is the latest maintenance release of the 1.0.x series. All users are encouraged to upgrade to 1.1.x stable series and report bugs there. Shortlog of changes since 1.0.1: Eric Wong (8): SIGTTIN works after SIGWINCH fix delays in signal handling Rakefile: don't post freshmeat on empty changelogs Rakefile: capture prerelease tags configurator: use "__send__" instead of "send" configurator: reloading with unset values restores default gemspec: depend on Isolate 3.0.0 for dev doc: stop using deprecated rdoc CLI options === 2.0.0pre3 / 2010-10-09 00:06 UTC 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. === 2.0.0pre2 / 2010-10-07 07:23 UTC Internal changes/cleanups for Rainbows! === 2.0.0pre1 / 2010-10-06 01:17 UTC Mostly internal cleanups for future versions of Rainbows! and people trying out Rubinius. There are tiny performance improvements for Ruby 1.9.2 users which may only be noticeable with Rainbows!. There is a new dependency on the "kgio" library for kinder, gentler I/O :) Please report any bugs and portability issues with kgio to the Unicorn mailing list[1]. Unicorn 1.1.x users are NOT required nor even encouraged to upgrade yet. Unicorn 1.1.x will be maintained for the forseeable future. [1] - mongrel-unicorn@rubyforge.org === 1.1.4 / 2010-10-04 20:32 UTC We no longer unlinking actively listening sockets upon startup (but continue to unlink dead ones). This bug could trigger downtime and nginx failures if a user makes an error and attempts to start Unicorn while it is already running. Thanks to Jordan Ritter for the detailed bug report leading to this fix. ref: http://mid.gmane.org/8D95A44B-A098-43BE-B532-7D74BD957F31@darkridge.com There are also minor documentation and test updates pulled in from master. This is hopefully the last bugfix release of the 1.1.x series. === 1.1.3 / 2010-08-28 19:27 UTC This release fixes race conditions during SIGUSR1 log cycling. This bug mainly affects Rainbows! users serving static files, but some Rack apps use threads internally even under Unicorn. Other small fixes: * SIGTTIN works as documented after SIGWINCH * --help output from `unicorn` and `unicorn_rails` is more consistent === 1.1.2 / 2010-07-13 20:04 UTC This release is fixes a long-standing bug where the original PID file is not restored when rolling back from a USR2 upgrade. Presumably most upgrades aren't rolled back, so it took over a year to notice this issue. Thanks to Lawrence Pit for discovering and reporting this issue. === 1.0.1 / 2010-07-13 20:01 UTC The first maintenance release of 1.0.x, this release is primarily to fix a long-standing bug where the original PID file is not restored when rolling back from a USR2 upgrade. Presumably most upgrades aren't rolled back, so it took over a year to notice this issue. Thanks to Lawrence Pit for discovering and reporting this issue. There is also a pedantic TeeInput bugfix which shouldn't affect real apps from the 1.1.x series and a test case fix for OSX, too. === 1.1.1 / 2010-07-11 02:13 UTC Unicorn::TeeInput constant resolution for Unicorn::ClientError got broken simplifying code for RDoc. This affects users of Rainbows! and Zbatery. === 1.1.0 / 2010-07-08 07:57 UTC This is a small, incremental feature release with some internal changes to better support upcoming versions of the Rainbows! and Zbatery web servers. There is no need to upgrade if you're happy with 1.0.0, but also little danger in upgrading. There is one pedantic bugfix which shouldn't affect anyone and small documentation updates as well. === 1.0.0 / 2010-06-17 09:18 UTC 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. [4] http://github.com/evanphx/rubinius/issues/373 === 0.991.0 / 2010-06-11 02:18 UTC 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. === 0.990.0 / 2010-06-08 09:41 UTC 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 Iñaki 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.

Previously we had complicated ways to avoid loading Rack until after the application was loaded to allow the application to load an alternate version of Rack. However this has proven too error-prone to be worth supporting even though Unicorn does not have strict requirements on currently released Rack versions. If an app requires a different version of Rack than what Unicorn would load by default, it is recommended they only install that version of Rack (and no others) since Unicorn does not have any strict requirements on currently released Rack versions. Rails 2.3.x users should be aware of this as those versions are not compatible with Rack 1.1.0. If it is not possible to only have one Rack version installed "globally", then they should either use Isolate or Bundler and install a private version of Unicorn along with their preferred version of Rack. Users who install in this way are recommended to execute the isolated/bundled version of Unicorn, instead of what would normally be in $PATH. Feedback/tips to mailto:mongrel-unicorn@rubyforge.org from Isolate and Bundler users would be greatly appreciated. === 0.98.0 / 2010-05-05 00:53 UTC 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. === 0.97.1 / 2010-04-19 21:00 UTC This release fixes a denial-of-service vector for derived servers exposed directly to untrusted clients. This bug does not affect most Unicorn deployments as Unicorn is only supported with trusted clients (such as nginx) on a LAN. nginx is known to reject clients that send invalid Content-Length headers, so any deployments on a trusted LAN and/or behind nginx are safe. Servers affected by this bug include (but are not limited to) Rainbows! and Zbatery. This bug does not affect Thin nor Mongrel, as neither got the request body filtering treatment that the Unicorn HTTP parser got in August 2009. The bug fixed in this release could result in a denial-of-service as it would trigger a process-wide assertion instead of raising an exception. For servers such as Rainbows!/Zbatery that serve multiple clients per worker process, this could abort all clients connected to the particular worker process that hit the assertion. === 0.97.0 / 2010-03-01 18:26 UTC 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. === 0.96.1 / 2010-02-13 08:35 UTC 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. === 0.96.0 / 2010-01-08 05:18 UTC 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!). === 0.95.3 / 2009-12-21 21:51 UTC 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. === 0.95.2 / 2009-12-07 09:52 UTC 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. === 0.95.1 / 2009-11-21 21:13 UTC 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 === 0.95.0 / 2009-11-15 22:21 UTC 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! Load Unicorn constants when building app tee_input: fix RDoc argument definition for tee Add FAQ FAQ: fix links to Configurator docs tee_input: better premature disconnect handling tee_input: don't shadow struct members raise Unicorn::ClientShutdown if client aborts in TeeInput tee_input: fix comment from an intermediate commit FAQ: additional notes on getting HTTPS redirects right configurator: update RDoc and comments in examples bump version to 0.95.0pre configurator: listen :umask parameter for UNIX sockets preserve user/group ownership when reopening logs old_rails/static: avoid freezing strings old_rails: autoload Static const: no need to freeze HTTP_EXPECT test_server: ensure stderr is written to before reading tee_input: expand client error handling replace "rescue => e" with "rescue Object => e" socket_helper: do not hide errors when setting socket options socket_helper: RDoc for constants ClientShutdown: RDoc Rakefile: add raa_update task tee_input: client_error always raises === 0.94.0 / 2009-11-05 09:52 UTC 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). === 0.93.5 / 2009-10-29 21:41 UTC 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) === 0.93.4 / 2009-10-27 07:57 UTC 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. Andrey Stikheev (1): workaround FreeBSD/OSX IO bug for large uploads Eric Wong (7): DESIGN: address concerns about on-demand and thundering herd README: alter reply conventions for the mailing list configurator: stop testing for non-portable listens KNOWN_ISSUES: document Rack gem issue w/Rails 2.3.2 stop continually resends signals during shutdowns add news bodies to site NEWS.atom.xml configurator: fix broken example in RDoc Suraj N. Kurapati (1): show configuration file path in errors instead of '(eval)' [1] http://redmine.ruby-lang.org/issues/show/2267 === 0.93.3 / 2009-10-09 22:50 UTC This release fixes compatibility with OpenBSD (and possibly other Unices with stricter fchmod(2) implementations) thanks to Jeremy Evans. Additionally there are small documentation changes all around. Eric Wong (12): doc: expand on the SELF_PIPE description fchmod heartbeat flips between 0/1 for compatibility examples/init.sh: remove "set -u" configurator: update with nginx fail_timeout=0 example PHILOSOPHY: clarify experience other deployments PHILOSOPHY: plug the Rainbows! spin-off project README: remove unnecessary and extraneous dash DESIGN: clarification and possibly improve HTML validity README: remove the "non-existent" part README: emphasize the "fast clients"-only part drop the whitespace cleaner for Ragel->C unicorn 0.93.3 === 0.93.2 / 2009-10-07 08:45 UTC 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): Fix NEWS generation on single-paragraph tag messages Include GPLv2 in docs doc: make it clear contributors retain copyrights TODO: removed Rainbows! (see rainbows.rubyforge.org) Document the START_CTX hash contents more-compatible TeeInput#read for POSTs with Content-Length tests for read-in-full vs readpartial semantics unicorn 0.93.2 === 0.93.1 / 2009-10-03 01:17 UTC Fix permissions for release tarballs/gems, no other changes. Thanks to Jay Reitz for reporting this. === 0.93.0 / 2009-10-02 21:04 UTC 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. Eric Wong (55): build: hardcode the canonical git URL build: manifest dropped manpages build: smaller ChangeLog doc/LATEST: remove trailing newline http: don't force -fPIC if it can't be used .gitignore on *.rbc files Rubinius generates README/gemspec: a better description, hopefully GNUmakefile: add missing .manifest dep on test installs Add HACKING document configurator: fix user switch example in RDoc local.mk.sample: time and perms enforcement unicorn_rails: show "RAILS_ENV" in help message gemspec: compatibility with older Rubygems Split out KNOWN_ISSUES document KNOWN_ISSUES: add notes about the "isolate" gem gemspec: fix test_files regexp match gemspec: remove tests that fork from test_files test_signals: ensure we can parse pids in response GNUmakefile: cleanup test/manifest generation util: remove APPEND_FLAGS constant http_request: simplify and remove handle_body method http_response: simplify and remove const dependencies local.mk.sample: fix .js times TUNING: notes about benchmarking a high :backlog HttpServer#listen accepts :tries and :delay parameters "make install" avoids installing multiple .so objects Use Configurator#expand_addr in HttpServer#listen configurator: move initialization stuff to #initialize Remove "Z" constant for binary strings cgi_wrapper: don't warn about stdoutput usage cgi_wrapper: simplify status handling in response cgi_wrapper: use Array#concat instead of += server: correctly unset reexec_pid on child death configurator: update and modernize examples configurator: add colons in front of listen() options configurator: remove DEFAULT_LOGGER constant gemspec: clarify commented-out licenses section Add makefile targets for non-release installs cleanup: use question mark op for 1-byte comparisons RDoc for Unicorn::HttpServer::Worker small cleanup to pid file handling + documentation rails: RAILS_RELATIVE_URL_ROOT may be set in Unicorn config unicorn_rails: undeprecate --path switch manpages: document environment variables README: remove reference to different versions Avoid a small window when a pid file can be empty configurator: update some migration examples configurator: listen :delay must be Numeric test: don't rely on .manifest for test install SIGNALS: state that we stole semantics from nginx const: DEFAULT_PORT as a string doesn't make sense test_helper: unused_port rejects 8080 unconditionally GNUmakefile: SINCE variable may be unset tests: GIT-VERSION-GEN is a test install dependency unicorn 0.93.0 === 0.92.0 / 2009-09-18 21:40 UTC 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. Those unfamiliar with Atom or HTTP may finger unicorn@bogomips.org for the latest announcements. Eric Wong (53): README: update with current version http: cleanup and avoid potential signedness warning http: clarify the setting of the actual header in the hash http: switch to macros for bitflag handling http: refactor keepalive tracking to functions http: use explicit elses for readability http: remove needless goto http: extra assertion when advancing p manually http: verbose assertions http: NIL_P(var) instead of var == Qnil http: rb_gc_mark already ignores immediates http: ignore Host: continuation lines with absolute URIs doc/SIGNALS: fix the no-longer-true bit about socket options "encoding: binary" comments for all sources (1.9) http_response: don't "rescue nil" for body.close CONTRIBUTORS: fix capitalization for why http: support Rubies without the OBJ_FROZEN macro 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 http: cleanup assertion for memoized header strings http: add #endif comment labels where appropriate Add .mailmap file for "git shortlog" and other tools Update Manifest with mailmap Fix comment about speculative accept() SIGNALS: use "Unicorn" when referring to the web server Add new Documentation section for manpages test_exec: add extra tests for HUP and preload_app socket_helper: (FreeBSD) don't freeze the accept filter constant Avoid freezing objects that don't benefit from it SIGHUP no longer drops lone, default listener doc: generate ChangeLog and NEWS file for RDoc Remove Echoe and roll our own packaging/release... unicorn_rails: close parentheses in help message launchers: deprecate ambiguous -P/--p* switches man1/unicorn: avoid unnecessary emphasis Add unicorn_rails(1) manpage Documentation: don't force --rsyncable flag with gzip(1) Simplify and standardize manpages build/install GNUmakefile: package .tgz includes all generated files doc: begin integration of HTML manpages into RDoc Update TODO html: add Atom feeds doc: latest news is available through finger NEWS.atom: file timestamp matches latest entry pandoc needs the standalone switch for manpages man1/unicorn: split out RACK ENVIRONMENT section man1/unicorn_rails: fix unescaped underscore NEWS.atom.xml only lists the first 10 entries unicorn 0.92.0 === 0.10.3r / 2009-09-09 00:09 UTC Removes the Rev monkey patch, rev 0.3.0 is out now so we can just depend on that instead of monkey patching it. Experimental HTTP keepalive/pipelining support has arrived as well. Three features from mainline Unicorn are now working again with this branch: * Deadlocked workers can be detected by the master and nuked * multiple (TCP) listeners per process * graceful shutdown This (pre-)release does NOT feature HTTP/0.9 support that Unicorn 0.91.0 had, expect that when this branch is ready for merging with mainline. === 0.91.0 / 2009-09-04 19:04 UTC HTTP/0.9 support, multiline header support, small fixes 18 years too late, Unicorn finally gets HTTP/0.9 support as HTTP was implemented in 1991. Eric Wong (16): Documentation updates examples/echo: "Expect:" value is case-insensitive http: make strings independent before modification http: support for multi-line HTTP headers tee_input: fix rdoc unicorn_http: "fix" const warning http: extension-methods allow any tokens http: support for simple HTTP/0.9 GET requests test_http_parser_ng: fix failing HTTP/0.9 test case launcher: defer daemonized redirects until config is read test to ensure stderr goes *somewhere* when daemonized http: SERVER_PROTOCOL matches HTTP_VERSION http: add HttpParser#headers? method Support HTTP/0.9 entity-body-only responses Redirect files in binary mode unicorn 0.91.0 === 0.10.2r / 2009-08-18 22:28 UTC Two botched releases in one day, hopefully this is the last... Eric Wong (3): rainbows: monkey-patch Rev::TCPListener for now rainbows: make the embedded SHA1 app Rack::Lint-safe unicorn 0.10.2r === 0.10.1r / 2009-08-18 22:01 UTC Ruby 1.9 only, again Eric Wong (2): Actually hook up Rainbows to the rest of the beast unicorn 0.10.1r === 0.10.0r / 2009-08-18 21:41 UTC This "release" is for Ruby 1.9 only === 0.90.0 / 2009-08-17 00:24 UTC switch chunking+trailer handling to Ragel, v0.8.4 fixes Moved chunked decoding and trailer parsing over to C/Ragel. Minor bug fixes, internal code cleanups, and API changes. Eric Wong (55): README: update version numbers for website Update Rails tests to run on Rails 2.3.3.1 README: latest stable version is 0.8.4 unicorn_http: small cleanups and size reduction Remove Ragel-generated file from version control unicorn_http: remove typedef from http_parser unicorn_http: update copyright unicorn_http: change "global_" prefix to "g_" unicorn_http: add helpful macros extconf: SIZEOF_OFF_T should be a ruby.h macro Refactoring unicorn_http C/Ragel code http: find_common_field_value => find_common_field http: split uncommon_field into a separate function http: remove some redundant functions http: "hp" denotes http_parser structs for consistency http: small cleanup in "https" detection http: minor cleanup of http_field handling http: split out server params handling http: move global initialization code http: cleanup setting for common values => globals http: remove noise functions http: move non-Ruby-specific macros c_util.h http: prepare http_parser struct for body processing http: generic C string vs VALUEs comparison function http: process Content-Length and Transfer-Encoding http: preliminary chunk decoding test_upload: extra CRLF is needed Switch to Ragel/C-based chunk/trailer parser http: unit tests for overflow and bad lengths http: add test for invalid trailer http: join repeated headers with a comma test_util: explicitly close tempfiles for GC-safety test_exec: wait for worker readiness Documentation updates test_signals: unlink log files of KILL-ed process http: rename read_body to filter_body http: add CONST_MEM_EQ macro http: add "HttpParser#keepalive?" method http: freeze fields when creating them, always README: everybody loves Ruby DSLs http_request: reinstate empty StringIO optimization tee_input: make interface more usable outside of Unicorn Drop the micro benchmarks http: fix warning when sizeof(off_t) == sizeof(long long) GNUmakefile: Fix "install" target Fix documentation for Util.reopen_logs http_response: pass through unknown status codes const: remove unused constants update TODO http: support for "Connection: keep-alive" TODO: remove keep-alive/pipelining Make launchers __END__-aware Remove explicit requires for Rack things app/inetd: explicitly close pipe descriptors on CatBody#close unicorn 0.90.0 === 0.8.4 / 2009-08-06 22:48 UTC pass through unknown HTTP status codes This release allows graceful degradation in case a user is using a status code not defined by Rack::Utils::HTTP_STATUS_CODES. A patch has been submitted[1] upstream to Rack but this issue may still affect users of yet-to-be-standardized status codes. Eric Wong (2): http_response: pass through unknown status codes unicorn 0.8.4 [1] - http://rack.lighthouseapp.com/projects/22435-rack/tickets/70 === 0.9.2 / 2009-07-20 01:29 UTC Ruby 1.9.2 preview1 compatibility This release mainly fixes compatibility issues the Ruby 1.9.2 preview1 release (and one existing 1.9.x issue). Note that Rails 2.3.2.1 does NOT appear to work with Ruby 1.9.2 preview1, but that is outside the scope of this project. The 0.9.x series (including this release) is only recommended for development/experimental use. This series is NOT recommended for production use, use 0.8.x instead. Eric Wong (10): README: add Gmane newsgroup info README: update about development/stable versions Rename unicorn/http11 => unicorn_http move all #gets logic to tee_input out of chunked_reader http_request: don't support apps that close env["rack.input"] HttpRequest: no need for a temporary variable Remove core Tempfile dependency (1.9.2-preview1 compat) fix tests to run correctly under 1.9.2preview1 app/exec_cgi: fix 1.9 compatibility unicorn 0.9.2 === 0.8.3 / 2009-07-20 01:26 UTC Ruby 1.9.2 preview1 compatibility This release fixes compatibility issues the Ruby 1.9.2 preview1 release (and one existing 1.9.x issue). Note that Rails 2.3.2.1 does NOT appear to work with Ruby 1.9.2 preview1, but that is outside the scope of this project. Eric Wong (4): Remove core Tempfile dependency (1.9.2-preview1 compat) fix tests to run correctly under 1.9.2preview1 app/exec_cgi: fix 1.9 compatibility unicorn 0.8.3 === 0.8.2 / 2009-07-09 08:59 UTC 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): Unbind listeners as before stopping workers Retry listen() on EADDRINUSE 5 times every 500ms Re-add support for non-portable socket options Minor cleanups to core always set FD_CLOEXEC on sockets post-accept() unicorn 0.8.2 === 0.9.1 / 2009-07-09 08:49 UTC FD_CLOEXEC portability fix (v0.8.2 port) Minor cleanups, set FD_CLOEXEC on accepted listen sockets instead of relying on the flag to be inherited across accept. The 0.9.x series (including this release) is NOT recommended for production use, try 0.8.x instead. Eric Wong (10): Avoid temporary array creation Favor Struct members to instance variables Minor cleanups to core Unbind listeners as before stopping workers Retry listen() on EADDRINUSE 5 times ever 500ms Re-add support for non-portable socket options Minor cleanups to core (cherry picked from commit ec70433f84664af0dff1336845ddd51f50a714a3) always set FD_CLOEXEC on sockets post-accept() unicorn 0.8.2 unicorn 0.9.1 (merge 0.8.2) === 0.9.0 / 2009-07-01 22:24 UTC 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. Eric Wong (43): http_request: no need to reset the request http_request: StringIO is binary for empty bodies (1.9) http_request: fix typo for 1.9 Transfer-Encoding: chunked streaming input support Unicorn::App::Inetd: reinventing Unix, poorly :) README: update with mailing list info local.mk.sample: publish_doc gzips all html, js, css Put copyright text in new files, include GPL2 text examples/cat-chunk-proxy: link to proposed curl(1) patch Update TODO Avoid duplicating the "Z" constant Optimize body-less GET/HEAD requests (again) tee_input: Don't expose the @rd object as a return value exec_cgi: small cleanups README: another note about older Sinatra tee_input: avoid defining a @rd.size method Make TeeInput easier to use test_upload: add tests for chunked encoding GNUmakefile: more stringent error checking in tests test_upload: fix ECONNRESET with 1.9 GNUmakefile: allow TRACER= to be specified for tests test_rails: workaround long-standing 1.9 bug tee_input: avoid rereading fresh data "Fix" tests that break with stream_input=false inetd: fix broken constant references configurator: provide stream_input (true|false) option chunked_reader: simpler interface http_request: force BUFFER to be Encoding::BINARY ACK clients on "Expect: 100-continue" header Only send "100 Continue" when no body has been sent http_request: tighter Transfer-Encoding: "chunked" check Add trailer_parser for parsing trailers chunked_reader: Add test for chunk parse failure TeeInput: use only one IO for tempfile trailer_parser: set keys with "HTTP_" prefix TrailerParser integration into ChunkedReader Unbind listeners as before stopping workers Retry listen() on EADDRINUSE 5 times ever 500ms Re-add support for non-portable socket options Move "Expect: 100-continue" handling to the app tee_input: avoid ignoring initial body blob Force streaming input onto apps by default unicorn 0.9.0 === 0.8.1 / 2009-05-28 21:45 UTC safer timeout handling, more consistent reload behavior This release features safer, more descriptive timeout handling, more consistent reload behavior, and is a miniscule amount faster on "Hello World" benchmarks Eric Wong (7): doc: cleanup summary/description Fix potential race condition in timeout handling SIGHUP reloads app even if preload_app is true Make our HttpRequest object a global constant Avoid instance variables lookups in a critical path Consistent logger assignment for multiple objects unicorn 0.8.1 === 0.8.0 / 2009-05-26 22:59 UTC enforce Rack dependency, minor performance improvements and fixes The RubyGem now has a hard dependency on Rack.
