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
|
|
If a configuration directive is set at startup and later
unset, it correctly restores the original default value
as if it had never been set in the first place.
This applies to the majority of the configuration values with
a few exceptions:
* This only applies to stderr_path and stdout_path when
daemonized (the usual case, they'll be redirected to
"/dev/null"). When NOT daemonized, we cannot easily redirect
back to the original stdout/stderr destinations.
* Unsetting working_directory does not restore the
original working directory where Unicorn was started.
As far as we can tell unsetting this after setting it is
rarely desirable and greatly increases the probability of
user error.
(cherry picked from commit 51b2b90284000aee8d79b37a5406173c45ae212d)

It's less ambiguous since this is a network server after all.
(cherry picked from commit f62c5850d7d17d7b5e301a494f8bdf5be3674411)
|
|
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.
|
|
This was accidentally enabled when ready_pipe was developed.
While re-daemonizing appears harmless in most cases this makes
detecting backed-out upgrades from the original master process
impossible.
(cherry picked from commit 3f0f9d6d72cf17b34c130b86eb933bbc513b24b3)

Different threads may change $/ during execution, so cache it at
function entry to a local variable for safety. $/ may also be
of a non-binary encoding, so rely on Rack::Utils.bytesize to
portably capture the correct size.
Our string slicing is always safe from 1.9 encoding: both our
socket and backing temporary file are opened in binary mode,
so we'll always be dealing with binary strings in this class
(in accordance to the Rack spec).
(cherry picked from commit 1cd698f8c7938b1f19e9ba091708cb4515187939)

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.

While log reopening worked reliably for newly-created File
objects in the unit tests, the $stderr and $stdout handles that
get redirected did not get reopened reliably under Rubinius.
We work around this by relying on Rubinius internals and
directly setting the @path instance variable. This is harmless
for MRI and should be harmless for other any other Ruby
implementations we'll eventually support.

Rack 1.2 removed the +size+ method requirement, but we'll
still support it since Rack 1.2 doesn't _prohibit_ it, and
Rack 1.[01] applications will continue to exist for a while.
|
|
Rack 1.2 no longer requires "rack.input" objects respond
to size.
|
|
No point in having namespaces be classes when we never
create instances of them...
|
|
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.
|
|
While we're at it, inform people of why they might use
a symlink
|
|
|
|
|
|
Since we added support for the "working_directory" parameter, it
often became unclear where/when certain paths would be bound.
There are some extremely nasty dependencies and ordering issues
when doing this. It's all pretty fragile, but works for now
and we even have a full integration test to keep it working.
I plan on cleaning this up 2.x.x to be less offensive to look
at (Rainbows! and Zbatery are a bit tied to this at the moment).
Thanks to Pierre Baillet for reporting this.

Rainbows! and Zbatery have long been upgraded to
pass options to us.

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].

Since we accidentally dropped open_args a while back, nothing
seems to have broken :x So apparently MRI preserves it for us,
and test/unit/test_util.rb agrees.
|
|
Creating File objects while iterating ObjectSpace for File
objects may hit subtle bugs. It may only be safe in MRI, and
even then it's not behavior that sounds sane to rely on. So
stop doing it.
|

IO#reopen in Rubinius seems to munge the O_APPEND flag when passed a
path, however passing an actual IO object. However, at the system call
level, everything is the same.

...than "test ?r" and "test ?w"
Not everybody comes from a Unix shell programming background,
even though they *should* ;)
|
|
Rack::Lint in Rack 1.1.0 does not require a "close" method for
env["rack.logger"], and we never explicitly close our logger,
either. This more easily allows the use of alternative
Logger-like implementations such as SyslogLogger.
|
|
While second nature to myself, stderr_path may be an
overlooked configuration parameter for some users. Also,
add a minimal sample configuration file that is shorter
and hopefully less intimidating to new users.
|
|
This middleware allows configurable out-of-band garbage
collection outside of the normal request/response cycle.
It offers configurable paths (to only GC on expensive actions)
and intervals to limit GC frequency.
It is only expected to work well with Unicorn, as it would
hurt performance on single-threaded servers if they
have keepalive enabled. Obviously this does not work well
for multi-threaded or evented servers that serve multiple
clients at once.
|
|
Starting with this release, we'll always load Rack up front at
startup.
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.

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.
|
|
This is useful as a :listeners argument when setting up
Raindrops::Middleware (http://raindrops.bogomips.org/),
as it can be done automatically.

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.

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.
|
|
Allowing the "user" directive outside of after_fork reduces the
cognitive overhead for folks that do not need the complexity of
*_fork hooks. Using Worker#user remains supported as it offers
fine-grained control of user switching.
|
|
It's a waste of memory bandwidth to do memcpy() when we know
Unicorn::HttpParser (via rb_str_resize()) will allocate new
memory for the string for us. An empty String is "free",
as we've already paid the Object cost regardless.
|
|
We'll use struct members exclusively from now on instead of
throwing ivars into the mix. This allows us to _unofficially_
support direct access to more members easily. Unofficial
extensions may include the ability to splice(2)/tee(2) for
better performance.
This also makes our object size smaller across all Ruby
implementations as well, too (helps Rainbows! out).
|
|
The temporary paths we create to mimic script/server-emulation
did not work when working_directory was used. Now we defer
path creation until after working_directory is bound.
|
|
no point in using "next" here
|
|
Copy-on-write will always invalidate it regardless, and
the first request is likely to be slow for any app.
|
|
This constant hasn't been in active use in our Ruby code for
ages now. All HTTP header constraints are defined in the
C/Ragel HTTP parser and we have tests for them, so there's
no need to repeat ourselves.
|
|
There may be some large-ish internal changes for 0.97.0
|
|
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!).
|
|
* rack-1.1:
http_response: disallow blank, multi-value headers
local.mk.sample: use rack-1.1.0
bump "rack.version" env to [1,1]
set env["rack.logger"] for applications
|
|
The HeaderHash optimizations in Rack 1.1 interact badly with
Rails 2.3.5 (and possibly other frameworks/apps) which set
multi-value "Set-Cookie" headers without relying on the proper
methods provided by Rack::Utils.
While this is an issue with Rails not using properly, there
may be similar apps that make this mistake and Rack::Lint
does not guard against it.

Inspection of the MRI source reveals that IO#sync=true only
appears to only apply for writes. Though it could eventually
make sense to disable read buffering by setting IO#sync=true,
it does not appear to happen.
Of course we never read from $stdin anyways....
|
|
Rainbows! does not yet know about ready_pipe, and will probably
not know about it until Unicorn 0.97.0
|
|
Rather than erroring out with a non-descript EOFError,
show a warning message telling users to check the logs
instead.

Otherwise the original spawner process may not notice the close
as it's still being shared by workers. While we're at it, avoid
confusing the original spawner by using readpartial instead of
sysread.
|
|
This behavior change also means our grandparent (launched
from a controlling terminal or script) will wait until
the master process is ready before returning.
Thanks to Iñaki Baz Castillo for the initial implementations
and inspiration.
|
|
This will match what's in Rack the 1.1.0 release.
|
|
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.
