init-hook no longer supports quoted code

[mathiasritter]

Bug Report

Since pylint version 2.14.2, the init-hook no longer supports quoted code. This is because with PR #6944, the function call to utils._unquote in pylint/config/config_initialization.py was removed: https://github.com/PyCQA/pylint/pull/6944/files#diff-dd2760aa48f0278b8c66e126913d22c0f9749cca892ef3c4104b957f4c899f68L48-R48

Example

To reproduce this bug, I created a small example repository with the following contents:

src/
    mypackage/
        file1.py
        file2.py
.pylintrc

The contents of file1.py are:

from mypackage.file2 import its_true

The contents of file2.py are:

its_true = True

The contents of .pylintrc are:

[MASTER]
init-hook='import sys; sys.path.append("src")'  # Note that code is quoted
disable=missing-module-docstring,unused-import

The purpose of the init-hook is to add the src directory to the python path, so pylint can locate all imports correctly.

Current Behaviour

When invoking pylint in the repository root with src/mypackage/file1.py, it is unable to import mypackage.file2:

❯ pylint src/mypackage/file1.py
************* Module file1
src/mypackage/file1.py:1:0: E0401: Unable to import 'mypackage.file2' (import-error)

However, pylint is able to import mypackage.file2 if I either

• unquote the init-hook code or
• downgrade pylint to version <= 2.14.1

Expected Behaviour

When running pylint src/mypackage/file1.py, pylint should be able to import mypackage.file2.

Environment Information

pylint version 2.14.2
python version 3.10.5
macOS version 12.3.1
