Justin M. Keyes 8a782f1699 input: set input stream to blocking on exit 
If stdin is non-blocking, many tools (e.g. cat(1), read(1)) which assume
that stdin is blocking, will break in odd ways:

  read: read error: 0: Resource temporarily unavailable
  cat: -: Resource temporarily unavailable
  rm: error closing file

libuv puts stdin in nonblocking mode, and leaves it that way at exit
(this is apparently by design). So, before this commit, this always
works (because the shell clobbers O_NONBLOCK):

  $ nvim --cmd q
  $ read

...but these forms do _not_ work:

  $ nvim --cmd q && read
  $ echo foo | nvim --cmd q && read
  $ nvim && read

After this commit, all of the above forms work.

Background:

437b4397b9 (diff-41f4d294430cd8c36538999d62681ae2)
https://github.com/fish-shell/fish-shell/issues/176#issuecomment-15800155

- bash (and other shells: zsh, tcsh, fish), upon returning to the
  foreground, always sets fd 0 back to blocking mode. This practice only
  applies to stdin, _not_ stdout or stderr (in practice these fds may be
  affected anyways).
- bash/zsh/tcsh/fish do _not_ restore the non-blocking status of stdin
  when _resuming a job_.
- We do _not_ save/restore the original flags visible to
  fcntl(F_[SG]ETFL), because (counterintuitively) that isn't expected.

Closes #2086
Closes #2377

Note: The following implementation of stream_set_blocking() was
discarded, because it resulted in a failed libuv assertion[1]:

  int stream_set_blocking(int fd, bool blocking)
  {
    uv_pipe_t stream;
    uv_pipe_init(uv_default_loop(), &stream, 0);
    uv_pipe_open(&stream, fd);
    int retval = uv_stream_set_blocking((uv_stream_t *)&stream, blocking);
    uv_close((uv_handle_t *)&stream, NULL);
    return retval;
  }

[1] .deps/build/src/libuv/src/unix/core.c:833: uv__io_stop: Assertion `loop->watchers[w->fd] == w' failed.

Neovim is a project that seeks to aggressively refactor Vim in order to:

  • Simplify maintenance and encourage contributions
  • Split the work between multiple developers
  • Enable the implementation of new/modern user interfaces without any modifications to the core source
  • Improve extensibility with a new plugin architecture

For lots more details, see the wiki!

What's been done so far

See the progress page for a comprehensive list.

Throughput Graph

What's being worked on now

  • Port all IO to libuv
  • Convert legacy tests to Lua tests
  • VimL => Lua translator

How do I get it?

There is a formula for OSX/homebrew, a PKGBUILD for Arch Linux, RPM, deb, and more. See the wiki!

Contributing

...would be awesome! See the wiki for more details.
