Now that upstream curl supports this functionality, there's
no reason to duplicate it here as an example.
|
|
Eventually this (and ChunkedReader) may be done in C/Ragel
along with the existing HttpParser.
|
|
Just clarifying the license terms of the new code. Other files
should really have this notice in there as well.
|
|
This includes an example of tunneling the git protocol inside a
TE:chunked HTTP request. The example is unfortunately contrived
in that it relies on the custom examples/cat-chunk-proxy.rb
script in the client. My initial wish was to have a generic
tool like curl(1) operate like this:
cat > ~/bin/cat-chunk-proxy.sh <<EOF
#!/bin/sh
exec curl -sfNT- http://$1:$2/
EOF
chmod +x ~/bin/cat-chunk-proxy.sh
GIT_PROXY_COMMAND=cat-chunk-proxy.sh git clone git://0:8080/foo
Unfortunately, curl will attempt a blocking read on stdin before
reading the TCP socket; causing the git-clone consumer to
starve. This does not appear to be a problem with the new
server code for handling chunked requests.

This adds support for handling POST/PUT request bodies sent with
chunked transfer encodings ("Transfer-Encoding: chunked").
Attention has been paid to ensure that a client cannot OOM us by
sending an extremely large chunk.
This implementation is pure Ruby as the Ragel-based
implementation in rfuzz didn't offer a streaming interface. It
should be reasonably close to RFC-compliant but please test it
in an attempt to break it.
The more interesting part is the ability to stream data to the
hosted Rack application as it is being transferred to the
server. This can be done regardless if the input is chunked or
not, enabling the streaming of POST/PUT bodies can allow the
hosted Rack application to process input as it receives it. See
examples/echo.ru for an example echo server over HTTP.
Enabling streaming also allows Rack applications to support
upload progress monitoring previously supported by Mongrel
handlers.
Since Rack specifies that the input needs to be rewindable, this
input is written to a temporary file (a la tee(1)) as it is
streamed to the application the first time. Subsequent rewinded
reads will read from the temporary file instead of the socket.
Streaming input to the application is disabled by default since
applications may not necessarily read the entire input body
before returning. Since this is a completely new feature we've
never seen in any Ruby HTTP application server before, we're
taking the safe route by leaving it disabled by default.
Enabling this can only be done globally by changing the
Unicorn HttpRequest::DEFAULTS hash:
Unicorn::HttpRequest::DEFAULTS["unicorn.stream_input"] = true
Similarly, a Rack application can check if streaming input
is enabled by checking the value of the "unicorn.stream_input"
key in the environment hashed passed to it.
All of this code has only been lightly tested and test coverage
is lacking at the moment.

Ensure we preserve both internal and external encodings
when reopening logs.
|
|
Most of this should be applicable to Mongrel and other
web servers, too.
|
|
We no longer have anything outside of SocketHelper module in
that file, so just give it a more obvious name.

bind_listen takes a hash as its second parameter now, allowing
the addition of :sndbuf and :rcvbuf options to specify the size
of the buffers in bytes. These correspond to the SO_SNDBUF and
SO_RCVBUF options via setsockopt(2) respectively.
This also adds support for per-listener backlogs to be used.
However, this is only an internal API change and the changes
have not yet been exposed to the user via Unicorn::Configurator,
yet.
Also add a bunch of SocketHelper tests

This test requires Rack to be loaded and will not
run without it. This also seems broken on 1.9 still
with Rack 0.9.1...
|
|
This is a Rack handler that passes Rack::Lint running cgit
and so it has been lightly tested. No other CGI executables
have been run with it.
|
|
The daemonization logic between unicorn and unicorn_rails
scripts can definitely be shared.
Again: our daemonization logic is slightly non-standard since
our executables are designed to run in APP_ROOT/RAILS_ROOT and
not "/" like "normal" UNIX daemons.
|
|
|
|
It is no longer relevant (or working) with rackup compatibility.
|
|
The LICENSE file is pretty much the same text, so there's no
point in having both files other than making the licensing terms
ambiguous. COPYING only specifies "GPL" while LICENSE specifies
"GPL2" specifically.
|
|
Also, update the Manifest
|
|
Since I use it myself and also in the tests, we
might as well implement it correctly as a class method
so people can run it in their trap('USR2') hooks.
|
|
Avoid conflicting with existing (and future) Mongrel installs in
case either changes. Of course, this also allows us more
freedom to experiment and break the API if needed...
However, I'm only planning on making minor changes to
remove the amount of C code we have to maintain and
possibly some minor performance improvements.
|
|
|
|
Add a make task for updating it, too.
|
|
We're not using them and they don't seem useful in any
shape or form...
|
|
All tests for threading and semaphores have been removed. One
test was changed because it depended on a shared variable.
Tests will be replaced with tests to do process management
instead.
|
|
Avoid conflicting with existing Mongrel libraries since
we'll be incompatible and break things w/o disrupting
Mongrel installations.

Supporting corporate enterprise platforms isn't my style :P

Almost nirvana for CI.
