Hi all,
I'm noticing some odd behavior in an ERR trap with errtrace. It's
present in bash 3.2 and as well as 4.2. The simplest reproduction is
as follows:
------8<----------------------
#!/bin/bash
somefunc() {
false
echo "shouldn't see this"
}
set -E
trap -- 'return 1' ERR
somefunc
echo "should see this"
------8<----------------------
Both versions of bash throw an error, though fwiw the line number
differs: bash4 blames the line of where the trap is fired versus bash3
which blames the line where the trap is declared. The entire output of
the script is:
foo: line 4: return: can only `return' from a function or sourced
script
should see this
So, both versions give the intended behavior of returning from the
function despite the error. imo, there's a bug here somewhere, I'm
just not sure if it's the faulty error being thrown or if I shouldn't
be expecting the trap to work as it is when it's declared outside of a
function.
Regards,
Dave
