[BUG] REPL exit when pressing Ctrl-\

[knuesel]

Details

• Atom version: 1.45
• Julia version: 1.4
• OS: Ubuntu 18.04
• Package versions:
  • Atom.jl: 0.12.10
  • julia-client: 0.12.4
  • ink: 0.12.3

Steps to reproduce

1. Start a long-running call in the Juno REPL, for example sleep(10)
2. Press Ctrl-\

This sends SIGQUIT to the Julia process, resulting in Julia exiting:

julia> sleep(5)
^\
signal (3): Quit
in expression starting at none:0
pthread_cond_wait at /lib/x86_64-linux-gnu/libpthread.so.0 (unknown line)
uv_cond_wait at /workspace/srcdir/libuv/src/unix/thread.c:827
...
Julia has exited.
Press Enter to start a new session.

This might not be a bug technically as it is the expected behavior in a regular terminal. But in Atom Ctrl-\ is used to toggle the tree view, so it is likely to surprise and annoy Juno users.

This can be fixed by adding "Ctrl-\\" to whitelistedKeybindingsREPL.
