Earth day release of a server designed for low energy use!
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:
This releases includes a few kqueue-related bugfixes from
Lin Jen-Shin <godfat@godfat.org>. There's also some
shutdown_timeout-related bugfixes and some cleanups to
reduce dependencies on kgio.
extras/exec_cgi and extras/autoindex both got some minor
updates; the latter of which defaults to a dark scheme to save
power on OLED and CRT displays (it is Earth Day, after all :>)
Eric Wong (25):
doc: fix git URLs in README and HACKING
http_client: do not warn on do_pread overreach
remove IO#close_on_exec= calls
yahns/worker: shrink pipe under Linux
test/test_extras_exec_cgi.rb: improve test reliability
extras/exec_cgi: remove kgio dependency
extras/exec_cgi: update copyright year and use SPDX
extras/exec_cgi: @body_tip is always set
extras/exec_cgi: support Process.spawn options (e.g. RLIMIT_*)
server_mp: favor "Kernel#select" instead of "IO.select"
server_mp: remove redundant srand call
extras/exec_cgi: remove unecessary .freeze calls
server: respect shutdown_timeout
server: extra shutdown timeout debugging
wbuf: use IO#write directly in Ruby 2.5+ for writev
worker: rely on F_SETPIPE_SZ to set mininum value
remove calls to kgio_wait_* able
do not shutdown until listeners are all stopped
README: remove SMTP-based subscription info
sigevent_*: fixup non-eventfd path
README: note HTTPS support for HTTP/1.1
extras/autoindex: use dark colors by default
doc: update homepage to point to cgit install
doc: update wording to avoid "mailing list"
doc: remove inaccurate comment about "GNU-ism"
Lin Jen-Shin (2):
Add QueueQuitter#closed? to queue_quitter_pipe.rb
@srv.shutdown could raise Errno::ENOTCONN
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.

Otherwise, listeners may still be injecting into the queue
and new clients may be accepted.

It seems there is still a bug in the proxy code which causes
this timeout expiries to be missed.

Graceful shutdown is still a bit tricky...
