fix(terminal): swallow Ctrl+Z in agent sessions so it cannot suspend a running CLI
|
|
|
|
Ctrl+Z raises SIGTSTP on the pane's tty. In a `shell` session that is ordinary job control and
|
|
is left alone, but in an agent session suspending the CLI stops an unattended loop dead with no
|
|
visible output, the same failure shape as an XOFF freeze. The key is now swallowed in
|
|
`attachCustomKeyEventHandler` for every non-shell mode, and unconditionally in the
|
|
subagent/teammate terminals, which always run an agent CLI. The match is case-insensitive,
|
|
because Caps Lock flips `ev.key` to `'Z'` without setting `shiftKey` and a plain `=== 'z'`
|
|
check would let exactly the keystroke this exists to catch through.
|
|
|
|
This is defence in depth rather than a fix for the steady state: an agent CLI holds its tty in
|
|
raw mode with ISIG off, where ^Z is already inert. It covers the moments that are not the
|
|
steady state: the window before the CLI takes the tty at startup, and any point where it hands
|
|
the tty back. Two input paths are deliberately not covered and still reach the PTY: the mobile
|
|
keyboard accessory bar's one-shot Ctrl, and the CJK composition textarea when `cjkInputEnabled`
|
|
is on. Both are separate choke points to the PTY, and both are worth covering if this ever
|
|
turns out to matter in practice.
