Ah, I was just about to do this and I saw that someone already had. Could someone please pull this so the README looks nice on github? |

We need to ensure the portability of the sd_listen_fds emulation test, too, which didn't get tested on my FreeBSD 10.3 install due to it being on Ruby 2.2 Followup-to: 4ce6b00 ("test_exec: SO_KEEPALIVE value only needs to be true")

A couple of portability fixes from Dylan Thacker-Smith and Jeremy Evans since 5.3.0.pre1 over a week ago, but this looks ready for a stable release, today. When I started this over 8 years ago, I wondered if this would just end up being an April Fools' joke. Guess not. I guess I somehow tricked people into using a terribly marketed web server that cannot talk directly to untrusted clients :x Anyways, unicorn won't be able to handle slow clients 8 years from now, either, or 80 years from now. And I vow never to learn to use new-fangled things like epoll, kqueue, or threads :P Anyways, this is a largish release with several new features, and no backwards incompatibilities. Simon Eskildsen contributed heavily using TCP_INFO under Linux to implement the (now 5 year old) check_client_connection feature: https://bogomips.org/unicorn/Unicorn/Configurator.html#method-i-check_client_connection https://bogomips.org/unicorn-public/?q=s:check_client_connection&d:..20170401&x=t This also led to FreeBSD and OpenBSD portability improvements in one of our dependencies, raindrops: https://bogomips.org/raindrops-public/20170323024829.GA5190@dcvr/T/#u Jeremy Evans contributed several new features. First he implemented after_worker_exit to aid debugging: https://bogomips.org/unicorn/Unicorn/Configurator.html#method-i-after_worker_exit https://bogomips.org/unicorn-public/?q=s:after_worker_exit&d:..20170401&x=t#t And then security-related features to isolate workers. Workers may now chroot to drop access to the master filesystem, and the new after_worker_ready configuration hook now exists to aid with chroot support in workers: https://bogomips.org/unicorn/Unicorn/Configurator.html#method-i-after_worker_ready https://bogomips.org/unicorn/Unicorn/Worker.html#method-i-user https://bogomips.org/unicorn-public/?q=s:after_worker_ready&d:..20170401&x=t#t https://bogomips.org/unicorn-public/?q=s:chroot&d:..20170401&x=t#t Additionally, workers may run in a completely different VM space (nullifying preload_app and any CoW savings) with the new worker_exec option: https://bogomips.org/unicorn/Unicorn/Configurator.html#method-i-worker_exec https://bogomips.org/unicorn-public/?q=s:worker_exec&d:..20170401&x=t#t There are also several improvements to FreeBSD and OpenBSD support with the addition of these features. shortlog of changes since v5.2.0 (2016-10-31): Dylan Thacker-Smith (1): Check for Socket::TCP_INFO constant before trying to get TCP_INFO Eric Wong (30): drop rb_str_set_len compatibility replacement TUNING: document THP caveat for Linux users tee_input: simplify condition for IO#write remove response_start_sent http_request: freeze constant strings passed IO#write Revert "remove response_start_sent" t/t0012-reload-empty-config.sh: access ivars directly if needed t0011-active-unix-socket.sh: fix race condition in test new test for check_client_connection revert signature change to HttpServer#process_client support "struct tcp_info" on non-Linux and Ruby 2.2+ unicorn_http: reduce rb_global_variable calls oob_gc: rely on opt_aref_with optimization on Ruby 2.2+ http_request: reduce insn size for check_client_connection freebsd: avoid EINVAL when setting accept filter test-lib: expr(1) portability fix tests: keep disabled tests defined test_exec: SO_KEEPALIVE value only needs to be true doc: fix links to raindrops project http_request: support proposed Raindrops::TCP states on non-Linux ISSUES: expand on mail archive info + subscription disclaimer test_ccc: use a pipe to synchronize test doc: remove private email support address input: update documentation and hide internals. http_server: initialize @pid ivar gemspec: remove olddoc from build dependency doc: add version annotations for new features unicorn 5.3.0.pre1 doc: note after_worker_exit is also 5.3.0+ test_exec: SO_KEEPALIVE value only needs to be true (take #2) Jeremy Evans (7): Add after_worker_exit configuration option Fix code example in after_worker_exit documentation Add support for chroot to Worker#user Add after_worker_ready configuration option Add worker_exec configuration option Don't pass a block for fork when forking workers Check for SocketError on first ccc attempt Simon Eskildsen (1): check_client_connection: use tcp state on linux
