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:
yahns 1.11.0 - more minor updates
There's some minor test case fixes and documentation updates.
For OpenSSL users running the Ruby 2.3.0 preview releases,
we now use `exception: false' for for accept_nonblock to reduce
exceptions. Non-SSL I/O still uses kgio for now.
6 changes since 1.10.0:
wbuf: fix typo in bug check for sendfile gem
test_wbuf: deal with proper zero-copy for Unix sockets
README: clarify and update copyright year
doc: document and reference sd_listen_fds(3) behavior
test_server: fix race condition in hooks test
openssl_client: use `exception: false' for accept_nonblock
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.

Ruby 2.3 will support this feature to reduce allocations
for common errors.
