…llets#3802) isatty() now also catches KeyboardInterrupt (a BaseException, not an Exception). A second Ctrl-C landing while click prints its 'Aborted!' message inside the except Abort block previously raised a KeyboardInterrupt that escaped main() entirely and crashed the process instead of exiting cleanly. Adds regression tests covering both the isatty guard and the echo/abort crash path.

Summary
Fixes #3802. A second
KeyboardInterrupt(Ctrl-C) arriving while click prints its "Aborted!" message during exception handling could crash the process instead of exiting cleanly.Root cause
Click's
except Aborthandler inBaseCommand.main()prints the abort message viaecho("Aborted!"), which callsshould_strip_ansi()→isatty().isatty()guarded onlyexcept Exception, butKeyboardInterruptis aBaseException, so a second Ctrl-C raised while probing the stream'sisattyescapedmain()entirely.Fix
isatty()now also catchesKeyboardInterruptand returnsFalse(its safe default). No behavior change for normal streams.Verification
test_isatty_swallows_keyboard_interruptfails on pristinemain(aKeyboardInterruptis wrongly propagated) and passes with the fix.test_abort_echo_absorbs_keyboard_interrupt_in_isattyexercises theecho("Aborted!")crash path directly.tests/test_compat.py(177) + broad suite (tests/test_termui.py,test_basic.py,test_options.py,test_arguments.py) pass: 1298 passed, 18 skipped.Note: I used AI assistance to help locate and reproduce the failure mode; the fix and tests are mine.
