It's nearly there. The new test case in C03traps.ztst succeeds.
But if a function defined with sticky emulation sets a POSIX trap, and
that function is called from native zsh, then the old behaviour returns
and a subsequent function-local trap wipes out the global POSIX trap. So
this still kills my POSIX library functions that set a trap.
New test script that does not succeed yet:
#! Src/zsh -f
echo entering program
emulate sh -c 'spt() { trap "echo POSIX exit trap triggered" EXIT; }'
fn() {
trap "echo native zsh function-local exit trap triggered" EXIT
echo entering native zsh function
}
spt
fn
echo exiting program
Expected output is identical to that of the C03traps.ztst test case.
Many thanks,
