Array#each will do..

Oops

Rack::Utils::HeaderHash is still very expensive in Rack 1.2,
especially for simple things that we want to run as fast as
possible with minimal interference. HeaderHash is unnecessary
for most requests that do not send Content-Range in responses.
|
|
Some middlewares require the Rack env to be preserved all
the way through to close, so we'll ensure all request models
preserve it.
We also need to better response body wrappers/proxies always get
fired properly when returning. IO.copy_stream and "sendfile"
gem users could hit cases where wrappers did not fire properly.
|
|
Use a consistent "Client" naming to reduce confusion
|
|
Needless duplication sucks

Errno::EAGAIN is still a problem under Ruby 1.9.2, so try harder
to avoid it and use kgio methods. Even when 1.9.3 is available,
kgio will still be faster as exceptions are slower than normal
return values.
|
|
Once again we avoid documenting internals on the public
website and use code comments for other developers.
|
|
kgio_trywrite is superior if it is available.
|
|
Despite the large number of changes, most of it is code
movement here.
|
|
We get basic internal API changes from Unicorn,
code simplifications coming next.
|
|
This was always an issue, but not noticed until
0cd65fa1e01be369b270c72053cf21a3d6bcb45f ...

The FileStreamer class of EventMachine (and by extension
NeverBlock) unfortunately doesn't handle this. It's possible
to do with Revactor (since it uses Rev under the covers),
but we'll support what we can easily for now.
|
|
Since we suck at building websites, we just rely on RDoc as a
website builder. And since Rainbows! is an application server
(and not a programming library), our internal API should be of
little interest to end users.
Anybody interested in Rainbows! (or any other project) internals
should be reading the source.
|
|
Cramp monkey patches Rainbows internals for WebSockets
support and we forgot about it. Add a new integration
test to ensure this continues to work in the future
(and force us to update the test for newer Cramp).
|
|
We shouldn't ever spew errors to the stderr/logger
on client disconnects (ECONNRESET/EPIPE/etc...).
|
|
This hopefully allows the "sendfile" gem to be required
anywhere in the Rainbows!/Unicorn config file, and not
have to be required via RUBYOPT or the '-r' command-line
switch.
We also modularize HttpResponse and avoids singleton methods
in the response path. This (hopefully) makes it easier for
individual concurrency models to share code and override
individual methods.
|
|
While these models are designed to work with IO.copy_stream
under Ruby 1.9, it should be possible to run them under Ruby
1.8 without returning corrupt responses. The large file
response test is beefed up to compare SHA1 checksums of
the served file, not just sizes.

It's not worth the trouble and testability since having
a single thread tends to bottleneck if there's a bad
client.
|
|
This is based on an idea I originally had for Unicorn but never
implemented in Unicorn since the benefits were unproven and the
risks were too high.
