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.
