Assumes everything in the tarball is prefixed with a common directory. That common path is stripped and the contents are extracted to ``target_dir``, similar to passing ``-C {target} --strip-components 1`` to the ``tar`` command. Uses the streaming protocol to extract the contents from a stream in a single pass without loading the whole file into memory. >>> import urllib.request >>> url = getfixture('tarfile_served') >>> target = getfixture('tmp_path') / 'out' >>> tb = tarball(url, target_dir=target) >>> import pathlib >>> with tb as extracted: ... contents = pathlib.Path(extracted, 'contents.txt').read_text(encoding='utf-8') >>> assert not os.path.exists(extracted) If the target is not specified, contents are extracted to a directory relative to the current working directory named after the name of the file as extracted from the URL. >>> target = getfixture('tmp_path') >>> with pushd(target), tarball(url): ... target.joinpath('served').is_dir() True Nz.tar.gz� z.tgzzr|*)�fileobj�mode)�path�filter)r r �basename�replace�mkdir�urllib�request�urlopenr �open� extractall�strip_first_component�shutil�rmtree)�urlr �req�tfr r r �tarball) s " ,r$ ztarfile.TarInfo)�memberr c C s | j �dd�\}| _ | S )N�/� )�name�split)r% r �_r r r r W s r c G s dd� }t �|t| ��S )a� Compose any number of dependent context managers into a single one. The last, innermost context manager may take arbitrary arguments, but each successive context manager should accept the result from the previous as a single parameter. Like :func:`jaraco.functools.compose`, behavior works from right to left, so the context manager should be indicated from outermost to innermost. Example, to create a context manager to change to a temporary directory: >>> temp_dir_as_cwd = _compose(pushd, temp_dir) >>> with temp_dir_as_cwd() as dir: ... assert os.path.samefile(os.getcwd(), dir) c s � �fdd�}t �|�S )Nc ? s` � | i |���>}�|��}|V W d � n1 s40 Y W d � n1 sR0 Y d S �Nr )�args�kwargsZsaved�res��inner�outerr r �composedt s z/_compose.<locals>.compose_two.<locals>.composed)� contextlib�contextmanager)r0 r1 r2 r r/ r � compose_twos s z _compose.<locals>.compose_two)� functools�reduce�reversed)Zcmgrsr5 r r r �_compose_ s r9 c C sT |\}}}| t jt jt jfv rN|jtjkrNt �|tjtj B tj B � | |� n� dS )z> Add support for removing read-only files on Windows.
