We can split the process of interpreting configuration files into 2 steps: 1. The parsing the file contents from strings to value objects that can be understand by Python (for example a string with a comma separated list of keywords into an actual Python list of strings). 2. The expansion (or post-processing) of these values according to the semantics ``setuptools`` assign to them (for example a configuration field with the ``file:`` directive should be expanded from a list of file paths to a single string with the contents of those files concatenated) This module focus on the second step, and therefore allow sharing the expansion functions among several configuration file formats. **PRIVATE MODULE**: API reserved for setuptools internal usage only. � N)�iglob)� ConfigParser)� ModuleSpec)�chain) � TYPE_CHECKING�Callable�Dict�Iterable�Iterator�List�Mapping�Optional�Tuple�TypeVar�Union�cast)�Path)� ModuleType)�DistutilsOptionError� )� same_path)�SetuptoolsWarning)� Distribution)�ConfigDiscovery)�DistributionMetadata�_K�_VT)Z covariantc @ sF e Zd ZdZeed�dd�Zeee j e j f d�dd�Z dd � Z d S ) � StaticModulez>Proxy to a module object that avoids executing arbitrary code.)�name�specc C s. t �t�|j��� �}t| ��t� � | ` d S )N) �ast�parse�pathlibr �originZ read_bytes�vars�update�locals�self)r' r r �module� r) �@/tmp/pip-install-251nq386/setuptools/setuptools/config/expand.py�__init__B s zStaticModule.__init__)�returnc # s^ xX| j jD ]L� t� tj�r6� fdd�� jD �E d H q t� tj�r � jr � j� jfV q W d S )Nc 3 s | ]}|� j fV qd S )N)�value)�.0�target)� statementr) r* � <genexpr>J s z1StaticModule._find_assignments.<locals>.<genexpr>) r( �body� isinstancer ZAssign�targetsZ AnnAssignr- r/ )r' r) )r0 r* �_find_assignmentsG s z StaticModule._find_assignmentsc sX yt � fdd�| �� D ��S tk rR } zt| j� d� � ��|�W dd}~X Y nX dS )zHAttempt to load an attribute "statically", via :func:`ast.literal_eval`.c 3 s2 | ]*\}}t |tj�r|j� krt�|�V qd S )N)r3 r �Name�id� literal_eval)r. r/ r- )�attrr) r* r1 R s z+StaticModule.__getattr__.<locals>.<genexpr>z has no attribute N)�nextr5 � Exception�AttributeErrorr )r' r9 �er) )r9 r* � __getattr__N s zStaticModule.__getattr__N) �__name__� __module__� __qualname__�__doc__�strr r+ r r r �ASTr5 r> r) r) r) r* r ? s r )�patterns�root_dirr, c s� ddddddh}g }� p t �� � x�| D ]x�t�fdd�|D ��r|t j�t j�� ���}|�t� fd d�t|d d �D ��� q&t j� �� �� t j d �}|� |� q&W |S ) a Expand the list of glob patterns, but preserving relative paths. :param list[str] patterns: List of glob patterns :param str root_dir: Path to which globs should be relative (current directory by default) :rtype: list �*�?�[�]�{�}c 3 s | ]}|� kV qd S )Nr) )r. �char)r- r) r* r1 j s z glob_relative.<locals>.<genexpr>c 3 s& | ] }t j�|� ��t jd �V qdS )�/N)�os�path�relpath�replace�sep)r. rP )rF r) r* r1 n s T)� recursiverN ) rO �getcwd�anyrP �abspath�join�extend�sortedr rQ rR rS �append)rE rF Zglob_charactersZexpanded_valuesZ glob_pathrP r) )rF r- r* � glob_relativeZ s r\ )� filepathsr, c sR ddl m} tj�� p t�� �� � fdd�|| �D �}d�� fdd�t|�D ��S )z�Return the content of the files concatenated using `` `` as str This function is sandboxed and won't reach anything outside ``root_dir`` (By default ``root_dir`` is the current directory). r )�always_iterablec 3 s | ]}t j�� |�V qd S )N)rO rP rX )r. rP )rF r) r* r1 � s z read_files.<locals>.<genexpr>� c 3 s | ]}t |� �rt|�V qd S )N)� _assert_local� _read_file)r. rP )rF r) r* r1 � s )� setuptools.extern.more_itertoolsr^ rO rP rW rU rX �_filter_existing_files)r] rF r^ Z _filepathsr) )rF r* � read_filesy s rd c c s8 x2| D ]*}t j�|�r |V qt�d|�d�� qW d S )NzFile z cannot be found)rO rP �isfiler �emit)r] rP r) r) r* rc � s rc )�filepathr, c C s" t j| dd�� }|�� S Q R X d S )Nzutf-8)�encoding)�io�open�read)rg �fr) r) r* ra � s ra )rg rF c C s@ t tj�|��t tj�| ��jkr<d| �d|�d�}t|��dS )NzCannot access z (or anything outside �)T)r rO rP rW �parentsr )rg rF �msgr) r) r* r` � s "r` )� attr_desc� package_dirrF c C s� |p t �� }| �� �d�}|�� }d�|�}|p2d}t|||�\}}}t||�}ytt ||�|�S t k r� t ||�} t| |�S X dS )a� Reads the value of an attribute from a module. This function will try to read the attributed statically first (via :func:`ast.literal_eval`), and only evaluate the module if it fails. Examples: read_attr("package.attr") read_attr("package.module.attr") :param str attr_desc: Dot-separated string describing how to reach the attribute (see examples above) :param dict[str, str] package_dir: Mapping of package names to their location in disk (represented by paths relative to ``root_dir``). :param str root_dir: Path to directory containing all the packages in ``package_dir`` (current directory by default). :rtype: str �.r+ N) rO rU �strip�split�poprX � _find_module� _find_spec�getattrr r; � _load_spec) rp rq rF Z attrs_path� attr_name� module_name� _parent_pathrP r r( r) r) r* � read_attr� s r} )r{ � module_pathr, c C s2 t j�| |�}|p t j�| �}|d kr.t| ��|S )N)� importlib�util�spec_from_file_location� find_spec�ModuleNotFoundError)r{ r~ r r) r) r* rw � s rw )r r{ r, c C sF t | d|�}|tjkr tj| S tj�| �}|tj|< | j�|� |S )Nr? )rx �sys�modulesr r� �module_from_spec�loader� exec_module)r r{ r r( r) r) r* ry � s ry )r{ rq rF r, c C s� |}| � d�}|r�|d |kr|||d }|�dd�}t|�dkr^tj�||d �}|d }n|}d�|f|dd� ��} nd|kr�tj�||d �}tjj|f| � d��� }t|� d�tj�|d�ft|� d ���} td d � | D �d�} || | fS ) a0 Given a module (that could normally be imported by ``module_name`` after the build is complete), find the path to the parent directory where it is contained and the canonical name that could be used to import it considering the ``package_dir`` in the build configuration and ``root_dir`` rr r rN � N� z.pyz __init__.pyz.*c s s | ]}t j�|�r|V qd S )N)rO rP re )r. �xr) r) r* r1 � s z _find_module.<locals>.<genexpr>) rt �rsplit�lenrO rP rX r r r: ) r{ rq rF � parent_path� module_partsZ custom_path�parts� parent_moduleZ path_start� candidatesr~ r) r) r* rv � s& rv )�qualified_class_namerq rF r, c C s^ |p t �� }| �d�}| |d d� }| d|� }t|||�\}}}tt||�|�} t| |�S )z@Given a qualified class name, return the associated class objectrr r� N)rO rU �rfindrv ry rw rx ) r� rq rF �idx� class_name�pkg_namer| rP r{ r( r) r) r* � resolve_class� s r� )�valuesrq rF r, c s � �fdd�| � � D �S )z�Given a dictionary mapping command names to strings for qualified class names, apply :func:`resolve_class` to the dict values. c s i | ]\}}t |� ��|�qS r) )r� )r. �k�v)rq rF r) r* � <dictcomp> s z cmdclass.<locals>.<dictcomp>)�items)r� rq rF r) )rq rF r* �cmdclass s r� )� namespaces�fill_package_dirrF )r� rF r, c s ddl m} ddlm}m} | r.ddl m} n ddl m} |pBtj}|� ddg�}g } |dkrbi n|}t |||���� t � �d kr�t � fd d �d|fD ��r�|� d � d � x^� D ]V} t|| �} |j| f|�} | �| � | r�|�d �| ks�tj�| |�s�|�|| | �� q�W | S ) a Works similarly to :func:`setuptools.find_packages`, but with all arguments given as keyword arguments. Moreover, ``where`` can be given as a list (the results will be simply concatenated). When the additional keyword argument ``namespaces`` is ``True``, it will behave like :func:`setuptools.find_namespace_packages`` (i.e. include implicit namespaces as per :pep:`420`). The ``where`` argument will be considered relative to ``root_dir`` (or the current working directory when ``root_dir`` is not given). If the ``fill_package_dir`` argument is passed, this function will consider it as a similar data structure to the ``package_dir`` configuration parameter add fill-in any missing package location. :rtype: list r )�construct_package_dir)�unique_everseenr^ )�PEP420PackageFinder)� PackageFinder�whererr Nr� c 3 s | ]}t � d |� V qdS )r N)� _same_path)r. r� )�searchr) r* r1 = s z find_packages.<locals>.<genexpr>r� )�setuptools.discoveryr� rb r� r^ r� r� rO �curdirru �listr� �all� setdefault� _nest_path�findrY �getrP �samefiler% ) r� r� rF �kwargsr� r� r^ r� r� �packagesrP Z package_path�pkgsr) )r� r* � find_packages s* & r� )�parentrP r, c C s& |dkr | n t j�| |�}t j�|�S )N> r� rr )rO rP rX �normpath)r� rP r) r) r* r� M s r� )r- r, c C sV t | �r| � } tttttf | �} t| t�sRt| d�rJd�t t| ��} nd| } | S )z`When getting the version directly from an attribute, it should be normalised to string. �__iter__rr z%s) �callabler r r rC �intr3 �hasattrrX �map)r- r) r) r* �versionR s r� )� package_datar, c C s d| kr| � d�| d< | S )NrG r� )ru )r� r) r) r* �canonic_package_datad s r� )� data_filesrF r, c s$ t | t�r| S � fdd�| �� D �S )z�For compatibility with ``setup.py``, ``data_files`` should be a list of pairs instead of a dict.

Given the contents of entry-points file, process it into a 2-level dictionary (``dict[str, dict[str, str]]``).

Therefore in some cases we will need to run autodiscovery during the evaluation of the configuration. However, it is better to postpone calling package discovery as much as possible, because some parameters can influence it (e.g. ``package_dir``), and those might not have been processed yet. r )� distributionc C s || _ d| _d S )NF)�_dist�_called)r' r� r) r) r* r+ � s z!EnsurePackagesDiscovered.__init__c C s | j sd| _ | jjdd� dS )zBTrigger the automatic package discovery, if it is still necessary.TF)r N)r� r� � set_defaults)r' r) r) r* �__call__� s z!EnsurePackagesDiscovered.__call__c C s | S )Nr) )r' r) r) r* � __enter__� s z"EnsurePackagesDiscovered.__enter__c C s | j r| jj�� d S )N)r� r� r� Z analyse_name)r' Z _exc_typeZ _exc_valueZ _tracebackr) r) r* �__exit__� s z!EnsurePackagesDiscovered.__exit__)r, c C s | � | j j}|d kri S |S )N)r� rq )r' Zpkg_dirr) r) r* �_get_package_dir� s z)EnsurePackagesDiscovered._get_package_dirc C s t | j�S )zCProxy to ``package_dir`` that may trigger auto-discovery when used.)�LazyMappingProxyr� )r' r) r) r* rq � s z$EnsurePackagesDiscovered.package_dirN) r? r@ rA rB r+ r� r� r� r rC r� �propertyrq r) r) r) r* r� � s r� c @ st e Zd ZdZeg eeef f d�dd�Zeeef d�dd�Z eed�d d �Z e d�d d �Z e e d�d d�ZdS )r� a� Mapping proxy that delays resolving the target object, until really needed. >>> def obtain_mapping(): ... print("Running expensive function!") ... return {"key": "value", "other key": "other value"} >>> mapping = LazyMappingProxy(obtain_mapping) >>> mapping["key"] Running expensive function!
