Set PS4 in stack.sh to provide additional debug info
Add:
export PS4='+(${BASH_SOURCE}:${LINENO}): ${FUNCNAME[0]:+${FUNCNAME[0]}(): }'
To stack.sh to provide additional debug info. This will show the
filename, line number, function name, and the content of the line.
An example output line:
+++(/opt/stack/old/devstack/functions-common:675): get_field(): local data field
