This module is NOT meant to be directly imported! It has been designed such that it can be bootstrapped into Python as the implementation of import. As such it requires the injection of specific modules and attributes in order to work. One should use importlib as the public-facing version of this module.

A module's spec is the source for information about the module. For data associated with the module, including source, use the spec's loader. `name` is the absolute name of the module. `loader` is the loader to use when loading the module. `parent` is the name of the package the module is in. The parent is derived from the name. `is_package` determines if the module is considered a package or not. On modules this is reflected by the `__path__` attribute. `origin` is the specific location used by the loader from which to load the module, if that information is available. When filename is set, origin will match. `has_location` indicates that a spec's "origin" reflects a location. When this is True, `__file__` attribute of the module is set. `cached` is the location of the cached bytecode file, if any. It corresponds to the `__cached__` attribute. `submodule_search_locations` is the sequence of path entries to search when importing submodules. If set, is_package should be True--and False otherwise. Packages are simply modules that (may) have submodules. If a spec has a non-None value in `submodule_search_locations`, the import system will consider modules loaded from the spec as packages. Only finders (see importlib.abc.MetaPathFinder and importlib.abc.PathEntryFinder) should modify ModuleSpec instances. �originN� loader_state� is_packagec C sO | | _ | | _ | | _ | | _ | r0 g n d | _ d | _ d | _ d S)NF)r rl rt ru �submodule_search_locations� _set_fileattr�_cached)r r rl rt ru rv r r r r t s zModuleSpec.__init__c C s� d j | j � d j | j � g } | j d k rL | j d j | j � � | j d k rt | j d j | j � � d j | j j d j | � � S)Nz name={!r}z loader={!r}z origin={!r}z submodule_search_locations={}z{}({})z, ) r7 r rl rt �appendrw � __class__r �join)r r r r r r9 � s zModuleSpec.__repr__c C s� | j } yk | j | j k or | j | j k or | j | j k or | | j k or | j | j k or | j | j k SWn t k r� d SYn Xd S)NF)rw r rl rt �cached� has_locationri )r �other�smslr r r �__eq__� s zModuleSpec.__eq__c C sU | j d k rN | j d k rN | j rN t d k r9 t � t j | j � | _ | j S)N)ry rt rx �_bootstrap_external�NotImplementedError� _get_cached)r r r r r} � s zModuleSpec.cachedc C s | | _ d S)N)ry )r r} r r r r} � s c C s. | j d k r# | j j d � d S| j Sd S)z The name of the module's parent.N�.r$ )rw r � rpartition)r r r r �parent� s zModuleSpec.parentc C s | j S)N)rx )r r r r r~ � s zModuleSpec.has_locationc C s t | � | _ d S)N)�boolrx )r �valuer r r r~ � s ) r r r r r r9 r� �propertyr} �setterr� r~ r r r r rs O s # rs rt rv c C s� t | d � rn t d k r! t � t j } | d k rF | | d | �S| rR g n d } | | d | d | �S| d k r� t | d � r� y | j | � } Wq� t k r� d } Yq� Xn d } t | | d | d | �S)z5Return a module spec based on various loader methods.� get_filenameNrl rw rv Frt )r r� r� �spec_from_file_locationrv rV rs )r rl rt rv r� �searchr r r r^ � s" r^ c 5 C sv y | j } Wn t k r!

The 'globals' argument is used to infer where the import is occurring from to handle relative imports. The 'locals' argument is ignored. The 'fromlist' argument specifies what should exist as attributes on the module being imported (e.g. ``from module import <fromlist>``). The 'level' argument represents the package location to import from in a relative import (e.g. ``from ..pkg import mod`` would have a 'level' of 2). r$ Nr� )r� r� � partitionr� r r r r� ) r r� �localsr� r� rb �globals_r� �cut_offr r r � __import__ s #(r� c C s5 t j | � } | d k r+ t d | � � t | � S)Nzno built-in module named )r� r� rV r� )r ra r r r �_builtin_from_name5 s r� c C sJ | a | a t t � } x{ t j j � D]j \ } } t | | � r( | t j k r[ t } n t j | � r( t } n q( t | | � } t | | � q( Wt j t } xI d D]A } | t j k r� t | � } n t j | } t | | | � q� Wy t d � } Wn t k rd } Yn Xt | d | � t d � } t | d | � d S)z�Setup importlib by importing needed built-in modules and injecting them into the global namespace.
