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 �*/opt/alt/python37/lib64/python3.7/runpy.py�__init__ s z_TempModule.__init__c C sB | j }y| j�tj| � W n tk r0 Y nX | jtj|< | S )N)r r �append�sys�modules�KeyErrorr )r 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 )N)�value�object� _saved_value� _sentinel)r r r r r r / 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 3 s z_ModifiedArgv0.__enter__c G s | j | _| jtjd< d S )Nr )r r r r r! )r r r r r r 9 s z_ModifiedArgv0.__exit__N)r r r r r r r r r r r . 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( r3 c C s^ |dkr |n|j }t|��6}t|��" |jj}t| ||||||� W dQ R X W dQ R X |�� S )z5Helper to run code in new namespace with sys modifiedN)r) r r r �__dict__r3 �copy) r- r. r r/ r0 r1 r2 � temp_module� mod_globalsr r r �_run_module_codeX s r8 c C s0 | � d�r|d��| �d�\}}}|r�y t|� W nH tk rz } z*|jd ksh|j|krj|� |jd �sj� W d d }~X Y nX tj�| �}|d k r�t|d�s�ddl m } dj | |d�}|t |�� yt j�| �}W nJ ttttfk �r } z"d}||� | t| �j| ��| �W d d } ~ X Y nX |d k�r2|d | ��|jd k �r�| d k�sT| �d ��r\|d ��y| d } t| |�S |k �r� } z"| tjk�r�� |d || f ��W d d }~X Y nX |j} | d k�r�|d| ��y| �| �} W n2 tk �r } z|t |��|�W d 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 r0 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 �errorr0 �_�eZexistingr; �msg�specZexZ pkg_main_namer( r- r r r rP f sZ , rP c @ s e Zd ZdZdS )�_ErrorzBError that _run_module_as_main() should report without a tracebackN)r r r r r r r r rW � s rW Tc C s� y0|s| dkr t | t�\} }}ntt�\} }}W n: tk rj } z dtj|f }t�|� W dd}~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.
