2026-10-24-gemini-cli-preview-forwards-parent-signals-nightly-blocks-further-work-after-cancellation

Preview forwards parent signals; nightly blocks further work after cancellation. The bootstrap parent forwards termination signals to the child, with Windows-specific handling for interrupt/quit. Nightly installs headless termination handlers even without a TTY, checks cancellation before consuming more responses and before scheduling tool calls, and returns cancellation-shaped output. The latest UI repair stops continuation processing and suppresses automatic nudges after cancellation and other terminal outcomes. Stable’s history repair in section 2 does not include these execution-loop changes.

Channel: preview-or-beta. Half: both. Date: 2026-10-23.

Operator consequence: Test the nightly with the actual supervisor, piped input and output mode before relying on cancellation as a run boundary. Test that no new tool begins after cancellation as well as whether the already-running process stops. The implementation reduces the need to watch for a cancelled agent restarting itself; it does not establish process-tree termination across every platform or tool.
