[ANN] yahns 1.17.0 -_- sleepy app server for Ruby

(Eric Wong) #1

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.

*zzzzzzz*
