This allows Python code to play nicely with non-filesystem based PEP 302 importers when locating support scripts as well as when importing modules. � N)� read_code� get_importer� run_module�run_pathc @ s( e Zd ZdZdd� Zdd� Zdd� ZdS ) � _TempModulezCTemporarily replace a module in sys.modules with an empty namespacec C s || _ t�|�| _g | _d S �N)�mod_name�types� ModuleType�module� _saved_module��selfr � r � /usr/lib64/python3.8/runpy.py�__init__ s z_TempModule.__init__c C sB | j }z| j�tj| � W n tk r0 Y nX | jtj|< | S r )r r �append�sys�modules�KeyErrorr r r r r � __enter__ s z_TempModule.__enter__c G s. | j r| j d tj| j< n tj| j= g | _ d S �Nr )r r r r �r �argsr r r �__exit__) s z_TempModule.__exit__N)�__name__� __module__� __qualname__�__doc__r r r r r r r r s r c @ s$ e Zd Zdd� Zdd� Zdd� ZdS )�_ModifiedArgv0c C s || _ t� | _| _d S r )�value�object� _saved_value� _sentinel)r r r r r r 1 s z_ModifiedArgv0.__init__c C s0 | j | jk rtd��tjd | _ | jtjd< d S )Nz Already preserving saved valuer )r" r# � RuntimeErrorr �argvr )r r r r r 5 s z_ModifiedArgv0.__enter__c G s | j | _| jtjd< d S r )r# r r" r r% r r r r r ; s z_ModifiedArgv0.__exit__N)r r r r r r r r r r r 0 s r c C sn |dk r|� |� |dkr(d}|}d} n |j}|j}|j} |dkrH|j}|j ||| d|||d� t| |� |S )z)Helper to run code in nominated namespaceN)r �__file__� __cached__r � __loader__� __package__�__spec__)�update�loader�origin�cached�parent�exec) �codeZ run_globals� init_globalsr �mod_spec�pkg_name� script_namer, �fnamer. r r r � _run_code@ s* � r7 c C s^ |dkr |n|j }t|��6}t|��" |jj}t| ||||||� W 5 Q R X W 5 Q R X |�� S )z5Helper to run code in new namespace with sys modifiedN)r- r r r �__dict__r7 �copy) r1 r2 r r3 r4 r5 r6 � temp_module� mod_globalsr r r �_run_module_codeZ s �r< c C s2 | � d�r|d��| �d�\}}}|r�z t|� W nH tk rz } z*|jd ksh|j|krj|� |jd �sj� W 5 d }~X Y nX tj�| �}|d k r�t|d�s�ddl m } dj | |d�}|t |�� zt j�| �}W nJ ttttfk �r } z"d}||� | t| �j| ��| �W 5 d } ~ X Y nX |d k�r2|d | ��|jd k �r�| d k�sT| �d ��r\|d ��z| d } t| |�W S |k �r� } z"| tjk�r�� |d || f ��W 5 d }~X Y nX |j} | d k�r�|d| ��z| �| �} W n2 tk �r } z|t |��|�W 5 d }~X Y nX | d k�r(|d| ��| || fS )N�.z#Relative module names not supported�__path__r )�warnz�{mod_name!r} found in sys.modules after import of package {pkg_name!r}, but prior to execution of {mod_name!r}; this may result in unpredictable behaviour)r r4 z:Error while finding module specification for {!r} ({}: {})zNo module named %s�__main__z .__main__z%Cannot use package as __main__ modulez3%s; %r is a package and cannot be directly executedz0%r is a namespace package and cannot be executedz No code object available for %s)� startswith� rpartition� __import__� ImportError�namer r �get�hasattr�warningsr? �format�RuntimeWarning� importlib�util� find_spec�AttributeError� TypeError� ValueError�typer �submodule_search_locations�endswith�_get_module_detailsr, �get_code) r �errorr4 �_�eZexistingr? �msg�specZexZ pkg_main_namer, r1 r r r rT h sd � � , � � rT c @ s e Zd ZdZdS )�_ErrorzBError that _run_module_as_main() should report without a tracebackN)r r r r r r r r r[ � s r[ Tc C s� z0|s| dkr t | t�\} }}ntt�\} }}W n: tk rj } z dtj|f }t�|� W 5 d}~X Y nX tjd j}|r�|jtj d< t ||dd|�S )a� Runs the designated module in the __main__ namespace Note that the executed module will have full access to the __main__ namespace.
