Yahns 1.4.0 -_- sleepy app server for Ruby

A Free Software, multi-threaded, non-blocking network application server
designed for low idle power consumption. It is primarily optimized
for applications with occasional users which see little or no traffic.
yahns currently hosts Rack/HTTP applications, but may eventually support
other application types. Unlike some existing servers, yahns is
extremely sensitive to fatal bugs in the applications it hosts.

Changes:

Minor internal cleanups and bugfixes.

* http_client: clear some internal ivars on rack.hijack
* README: minor updates
* extras/autoindex: do not link beyond top-level
* extras/autoindex: fix misnamed variable
* extras/autoindex: integrate with TryGzipStatic
* queue: remove TODO comment for kqueue
* switch to require_relative for internal requires
* README: add OpenSSL exception
* stream_input: favor str.clear instead of str.replace('')
* http_response: skip Date header case-insensitively

Please note the disclaimer:

yahns is extremely sensitive to fatal bugs in the apps it hosts.
There
is no (and never will be) any built-in “watchdog”-type feature to kill
stuck processes/threads. Each yahns process may be handling thousands
of clients; unexpectedly killing the process will abort all of those
connections. Lives may be lost!

yahns hackers are not responsible for your application/library bugs.
Use an application server which is tolerant of buggy applications
if you cannot be bothered to fix all your fatal bugs.
