fix(cli): status bar no longer stays hidden after resize during idle - #49105
Merged
Conversation
The classic CLI status bar could vanish for the rest of a session: any terminal reflow (SIGWINCH from a tmux pane change, SSH window restore, font zoom) set _status_bar_suppressed_after_resize=True, but the flag was ONLY cleared on the next *submitted* user input. Resize then sit idle and the bottom chrome rendered at height 0 on every repaint — even with the refresh clock ticking — so the bar was gone until you typed and hit enter. Fix: _recover_after_resize now schedules a debounced unsuppress timer that clears the flag and repaints once the reflow settles (~0.35s), so the bar returns on its own during idle. The next-submit clear stays as a fast path. Fails open: any error in scheduling clears the flag immediately rather than leaving the bar stuck hidden.

Summary
The classic CLI status bar no longer vanishes for the rest of a session after a terminal resize.
_recover_after_resizenow schedules a debounced timer that clears the post-resize suppression once the reflow settles, so the bottom chrome returns on its own during idle.Root cause: any terminal reflow (SIGWINCH from a tmux pane change, SSH window restore, font zoom) set
_status_bar_suppressed_after_resize = True, but the flag was only cleared on the next submitted user input. Resize, then sit idle, and the dynamic status bar + input separators rendered at height 0 on every repaint — even with therefresh_intervalclock ticking — so the bar stayed gone until you typed and hit enter.This is the deeper bug behind the "status bar disappears after a while" reports, separate from the #45592/#48309 refresh-interval default.
Changes
cli.py:_recover_after_resizeschedules_schedule_status_bar_unsuppress(debounced ~0.35s) which clears the flag and repaints. Fails open — any scheduling error clears the flag immediately. New_status_bar_unsuppress_timerinit.tests/cli/test_cli_status_bar.py: regression tests for self-clear during idle (no input) and resize-storm debounce; updated stale docstring.Validation
tests/cli/test_cli_status_bar.pyinvalidate()fires, rule height 0→1The next-submit clear at the input loop stays as a fast path; nothing about the duplicate-bar protection (#19280, #22976) changes — the suppression still covers the reflow window, it just no longer waits for input to end.
