If the backing stream for a :terminal was closed (e.g. if the shell exits unexpectedly) there may be pending input on the loop which will be processed before the terminal close event (which is queued on the same loop). terminal_send checks term->closed but this does not reflect the state of the underlying streams. The terminal.c module in fact has no knowledge of the streams (this seems intentional: it is abstracted as TerminalOption.write_cb). The SIGCHLD handler (pty_process_unix.c) is executed immediately, and it triggers a stream teardown so Stream.closed=false (TerminalJobData.in.closed). When the pending writes are handled by eval.c:term_write, wstream_write() aborts because it sees the closed Stream. To avoid that, this commit checks Stream.closed in eval:term_write() before writing to the WStream. (As hinted above, we cannot do this in terminal:terminal_send() because that module cannot inspect the underlying streams.)

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 UIs without modifications to the core
- Improve extensibility with a new plugin architecture
For more details, see the wiki!
What's been done so far
- RPC API based on MessagePack
- Embedded terminal emulator
- Asynchronous job control
- Shared data (shada) among multiple editor instances
- XDG base directories support
- libuv-based platform/OS/"mch" layer
- Pushdown automaton input model
- 1000s of new tests
- Legacy tests converted to Lua tests
See :help nvim-features for a comprehensive list.
What's being worked on now
See the Roadmap.
How do I get it?
There is a formula for OSX/homebrew, a PKGBUILD for Arch Linux, RPM, deb, and more. See the wiki!
