pylint . is inconsistent with pylint ../$(basename $(pwd))

[tom-d]

Steps to reproduce

mkdir tmp
touch __init__.py
mkdir tmp/lib
echo 'a = b' > tmp/lib/__init__.py
cd tmp

Current behavior

pylint . && echo $?
0

pylint ../tmp
E0602: Undefined variable 'b' (undefined-variable)

(cd .. && pylint tmp)
E0602: Undefined variable 'b' (undefined-variable)

Expected behavior

pylint .
E0602: Undefined variable 'b' (undefined-variable)

pylint --version output

pylint 2.1.1

correction to the above steps to reproduce..

mkdir tmp
touch tmp/__init__.py
mkdir tmp/lib
echo 'a = b' > tmp/lib/__init__.py
cd tmp

Thanks for creating an issue @tom-d !

This is fixed by using the --recursive=y option, and will be definitely fixed with #5701
