Severity: 3-Major

Symptoms

When using tmsh interactively in a terminal window, resizing the window can cause problems.

Impact

- If text has been typed, resizing the window will clear the text. - Certain commands such as 'load sys ucs' will be killed prematurely if the window is resized before they finish running. - Resizing the window while using imish or typing 'term len 0' will cause imish to be aborted.

Conditions

1. Run tmsh from a terminal window (or use tmsh as default shell). 2. - Type some text, then resize the window. or - Run a command, and resize the window before it finishes. or - Use a command that adjusts terminal size.

Workaround

Limit window resizing to sitting at an empty tmsh prompt.
