Shell integration breaks existing DEBUG traps in bash #146873
Description
Issue Type: Bug
- Add
trap something DEBUGto your .bashrc - Enable shell integration in VSCode
- Launch a shell in VSCode
- Observe that
somethingdoes not get called; the shell integration script has replaced your DEBUG trap with its own
In the case of PROMPT_COMMAND, VSCode goes to some effort to preserve an existing one, but in bash it shows no such consideration for DEBUG traps.
Preserving an existing DEBUG trap is possible; both iTerm2's shell integration and starship.rs do so. An existing DEBUG trap can be detected with trap -p DEBUG.
