Interactive Shell

It would be nice to automate this, but for now we should do basic manual testing upon release:

• Hit Tab for completions
• Hit tab in the middle of the line
• Hit tab on second line
• Change the window size and hit tab again

Signals:

• Ctrl-C, Ctrl-\ in the shell
• sleep 5, Ctrl-Z, then fg
• Start cat and run Ctrl-C, Ctrl-Z, Ctrl-\
• Start cat | head and run Ctrl-C, Ctrl-Z, Ctrl-\
• Start a builtin read and run Ctrl-C, Ctrl-Z, Ctrl-\
• sleep 5 &, then wait
  • then Ctrl-C
• time for i in $(seq 1000000); do true; done and Ctrl-C -- busy loop should be cancellable. (zsh has problems here.)
• Test signal in NON-interactive shell:
  • osh -c 'sleep 5' and then Ctrl-C
  • demo/ctrl-c.sh loop, then Ctrl-C
• User handlers: trap 'echo hi' INT, and then hit Ctrl-C
  • demo/trap.sh sigint-batch, sigterm-batch

SIGWINCH:

• Resize window and hit tab in a directory with many entries

Other:

• Ctrl-D to exit shell
