[ANN] unicorn 5.4.0 - Rack HTTP server for fast clients and Unix


(Eric Wong) #1

unicorn is an HTTP server for Rack applications designed to only serve
fast clients on low-latency, high-bandwidth connections and take
advantage of features in Unix/Unix-like kernels. Slow clients should
only be served by placing a reverse proxy capable of fully buffering
both the the request and response in between unicorn and slow clients.

Changes:

Rack hijack support improves as the app code can capture and use
the Rack `env' privately without copying it (to avoid clobbering
by another client). Thanks to Sam Saffron for reporting and
testing this new feature:

We also now support $DEBUG being set by the Rack app (instead of
relying on the "-d" CLI switch). Thanks to James P Robinson Jr
for reporting this bug:

  (Coincidentally, this fix will be irrelevant for Ruby 2.5
   which requires 'pp' by default)

There's a few minor test cleanups and documentation updates, too.

All commits since v5.3.1 (2017-10-03):

    reduce method calls with String#start_with?
    require 'pp' if $DEBUG is set by Rack app
    avoid reusing env on hijack
    tests: cleanup some unused variable warnings
    ISSUES: add a note about Debian BTS interopability

Changes:

    unicorn 5.4.1
    
    This release quiets some warnings for Ruby 2.6 preview releases
    and enables tests to pass under Ruby 1.9.3. Otherwise, nothing
    interesting for Ruby 2.0..2.5 users. *YAWN*
    
    Eric Wong (1):
          quiet some mismatched indentation warnings
    
    Fumiaki MATSUSHIMA (1):
          Use IO#wait instead to fix test for Ruby 1.9
