IronRuby 4.0.1

IronRuby 4.0.1 fixes pipes and sockets on macOS, where Puma could not start,
IO#write_nonblock on sockets, which cut large responses short, and a SQLite crash on
Linux. All of them were found by @rubys while serving Rails
apps that Roundhouse transpiles to plain Ruby.

Fixes

• Pipes to child processes work on macOS (#12). Backticks, %x(), IO.popen and
  Open3 failed with Errno::EINVAL: IronRuby passed Linux's value of O_CLOEXEC to
  pipe2, and macOS numbers the flag differently. On macOS, core/io/pipe_spec,
  core/kernel/backtick_spec and library/open3 now pass.
• Socket addresses on macOS and the BSDs (#13). Every address the kernel returned
  (getsockname, accept, recvfrom) raised unknown address family: 528, because a BSD
  sockaddr starts with a length byte; Puma could not bind. On macOS, ruby/spec
  library/socket errors fall from 838 to 178.
• IO#write_nonblock on a socket returns what the kernel took (#14). It claimed the
  whole string even when the kernel accepted only part of it, and the rest was lost: Puma
  responses larger than the socket's send buffer arrived truncated, on Linux and macOS.
  CI now checks that what write_nonblock claims is what the peer receives, on Linux and
  Windows (#15); Winsock takes a non-blocking send whole or refuses it, so Windows did not
  lose bytes.
• SQLite no longer crashes on Linux once another library has loaded the system SQLite
  (SQLitePCL.raw#682), libvips
  through ruby-vips for one. SQLitePCLRaw's libe_sqlite3.so is linked without
  -Bsymbolic, so its calls into itself could bind to the other copy, and
  SQLite3::Database.new segfaulted. The Linux archive now carries a libe_sqlite3.so
  built from the same SQLite 3.53.3 with the same compile options, linked -Bsymbolic.
  The release build checks that SQLite reports the same version and options from both, and
  that the rebuilt one still answers with the system's libsqlite3 preloaded. Windows and
  macOS were not affected.

Linux and Windows behave as in 4.0.0 apart from #14. The full status is in the
README.

Also new

• Issues are open.
• The launch video
  has music now, and plays inline in the README as a teaser.

Music in the launch video: Edvard Grieg, In the Hall of the Mountain King, played by the
Czech National Symphony Orchestra for Musopen; public domain, from
classicals.de.
