The package resource API expects resource names to have their path parts separated with ``/``, *not* whatever the local path separator is. Do not use os.path operations to manipulate resource names being passed into the API. The package resource API is designed to work with normal filesystem packages, .egg files, and unpacked .egg files. It can also work in a limited way with .zip files and with custom PEP 302 loaders that support the ``get_data()`` method. i N( u get_importer( u urlparseu urlunparse( u ImmutableSetc C s | j � S( N( u next( u o( ( u2 /tmp/pip-zej_zi-build/pip/_vendor/pkg_resources.pyu <lambda>- s u <lambda>( u StringIO( u BytesIOc C sY | d k r t � } n | d k r- | } n t t t | � j � | d � | | � d S( Nu exec( u Noneu globalsu execu compileu openu read( u fnu globsu locs( ( u2 /tmp/pip-zej_zi-build/pip/_vendor/pkg_resources.pyu execfile2 s u execfile( u utime( u mkdiru renameu unlink( u open( u isdiru spliti u cpythoni� c C s^ t s t d � � n t | � \ } } | rZ | rZ t | � rZ t | � t | | � n d S( Nu* "os.mkdir" not supported on this platform.( u WRITE_SUPPORTu IOErroru splitu isdiru _bypass_ensure_directoryu mkdir( u nameu modeu dirnameu filename( ( u2 /tmp/pip-zej_zi-build/pip/_vendor/pkg_resources.pyu _bypass_ensure_directoryP s u _bypass_ensure_directoryc K s- t � j | � t j t j | | � � d S( N( u globalsu updateu _state_varsu dictu fromkeys( u vartypeu kw( ( u2 /tmp/pip-zej_zi-build/pip/_vendor/pkg_resources.pyu _declare_state\ s u _declare_statec C sL i } t � } x6 t j � D]( \ } } | d | | | � | | <q W| S( Nu _sget_( u globalsu _state_varsu items( u stateu gu ku v( ( u2 /tmp/pip-zej_zi-build/pip/_vendor/pkg_resources.pyu __getstate__` s u __getstate__c C sJ t � } x: | j � D], \ } } | d t | | | | | � q W| S( Nu _sset_( u globalsu itemsu _state_vars( u stateu gu ku v( ( u2 /tmp/pip-zej_zi-build/pip/_vendor/pkg_resources.pyu __setstate__g s $u __setstate__c C s | j � S( N( u copy( u val( ( u2 /tmp/pip-zej_zi-build/pip/_vendor/pkg_resources.pyu _sget_dictm s u _sget_dictc C s | j � | j | � d S( N( u clearu update( u keyu obu state( ( u2 /tmp/pip-zej_zi-build/pip/_vendor/pkg_resources.pyu _sset_dictp s u _sset_dictc C s | j � S( N( u __getstate__( u val( ( u2 /tmp/pip-zej_zi-build/pip/_vendor/pkg_resources.pyu _sget_objectt s u _sget_objectc C s | j | � d S( N( u __setstate__( u keyu obu state( ( u2 /tmp/pip-zej_zi-build/pip/_vendor/pkg_resources.pyu _sset_objectw s u _sset_objectc G s d S( N( u None( u args( ( u2 /tmp/pip-zej_zi-build/pip/_vendor/pkg_resources.pyu <lambda>z s c C s� t � } t j | � } | d k r~ t j d k r~ y3 d d j t � d d � � | j d � f } Wq~ t k rz Yq~ Xn | S( uZ Return this platform's maximum compatible version. distutils.util.get_platform() normally reports the minimum version of Mac OS X that would be required to *use* extensions produced by distutils. But what we want when checking compatibility is to know the version of Mac OS X that we are *running*. To allow usage of packages that explicitly require a newer version of Mac OS X, we must also know the current version of the OS.

The `full_env`, if supplied, should be an ``Environment`` contains all currently-available distributions. If `full_env` is not supplied, one is created automatically from the ``WorkingSet`` this method is called on, which will typically mean that every directory on ``sys.path`` will be scanned for distributions. `installer` is a standard installer callback as used by the ``resolve()`` method. The `fallback` flag indicates whether we should attempt to resolve older versions of a plugin if the newest version cannot be resolved. This method returns a 2-tuple: (`distributions`, `error_info`), where `distributions` is a list of the distributions found in `plugin_env` that were loadable, along with any other distributions that are needed to resolve their dependencies. `error_info` is a dictionary mapping unloadable plugin distributions to an exception instance describing the error that occurred.

It is *possible* to create pathological version coding schemes that will fool this parser, but they should be very rare in practice. The returned value will be a tuple of strings. Numeric portions of the version are padded to 8 digits so they will compare numerically, but without relying on how numbers compare relative to strings. Dots are dropped, but dashes are retained. Trailing zeros between alpha segments or dashes are suppressed, so that e.g. "2.4.0" is considered the same as "2.4". Alphanumeric parts are lower-cased. The algorithm assumes that strings like "-" and any alpha string that alphabetically follows "final" represents a "patch level". So, "2.4-1" is assumed to be a branch or patch of "2.4", and therefore "2.4.1" is considered newer than "2.4-1", which in turn is newer than "2.4". Strings like "a", "b", "c", "alpha", "beta", "candidate" and so on (that come before "final" alphabetically) are assumed to be pre-release versions, so that the version "2.4" is considered newer than "2.4a1". Finally, to handle miscellaneous cases, the strings "pre", "preview", and "rc" are treated as if they were "c", i.e. as though they were release candidates, and therefore are not as new as a version string that does not contain them, and "dev" is replaced with an '@' so that it sorts lower than than any other pre-release tag. u *u *finali u *final-u 00000000i����i����( u _parse_version_partsu loweru startswithu popu appendu tuple( u su partsu part( ( u2 /tmp/pip-zej_zi-build/pip/_vendor/pkg_resources.pyu parse_version� s c B s� | Ee Z d Z d Z f f d d d � Z d d � Z d d � Z d d d d d � Z d d d d � Z e d d d � � Z e d d d � � Z e d d d � � Z d S( u EntryPointu3 Object representing an advertised importable objectc C sn t | � s t d | � � n | | _ | | _ t | � | _ t j d d j | � � j | _ | | _ d S( Nu Invalid module nameu x[%s]u ,( u MODULEu ValueErroru nameu module_nameu tupleu attrsu Requirementu parseu joinu extrasu dist( u selfu nameu module_nameu attrsu extrasu dist( ( u2 /tmp/pip-zej_zi-build/pip/_vendor/pkg_resources.pyu __init__ s "u EntryPoint.__init__c C sf d | j | j f } | j r< | d d j | j � 7} n | j rb | d d j | j � 7} n | S( Nu %s = %su :u .u [%s]u ,( u nameu module_nameu attrsu joinu extras( u selfu s( ( u2 /tmp/pip-zej_zi-build/pip/_vendor/pkg_resources.pyu __str__ s u EntryPoint.__str__c C s d t | � S( Nu EntryPoint.parse(%r)( u str( u self( ( u2 /tmp/pip-zej_zi-build/pip/_vendor/pkg_resources.pyu __repr__# s u EntryPoint.__repr__c C s� | r | j | | � n t | j t � t � d g � } xO | j D]D } y t | | � } WqD t k r� t d | | f � � YqD XqD W| S( Nu __name__u %r has no %r attribute( u requireu __import__u module_nameu globalsu attrsu getattru AttributeErroru ImportError( u selfu requireu envu installeru entryu attr( ( u2 /tmp/pip-zej_zi-build/pip/_vendor/pkg_resources.pyu load& s ! u EntryPoint.loadc C s] | j r% | j r% t d | � � n t t t j t j | j j | j � | | � � � d S( Nu& Can't require() without a distribution( u extrasu distu UnknownExtrau listu mapu working_setu addu resolveu requires( u selfu envu installer( ( u2 /tmp/pip-zej_zi-build/pip/_vendor/pkg_resources.pyu require0 s u EntryPoint.requirec C s y� f } } | j d d � \ } } d | k rz | j d d � \ } } t j d | � } | j rn t � n | j } n d | k r� | j d d � \ } } t | j � � s� t � n | j � j d � } n Wn! t k r� t d | � � Yn# X| | j � | j � | | | � Sd S( u Parse a single entry point from string `src` Entry point syntax follows the form:: name = some.module:some.attr [extra1,extra2] The entry name and module name are required, but the ``:attrs`` and ``[extras]`` parts are optional u =i u [u x[u :u .u9 EntryPoint must be in 'name=module:attrs [extras]' formatN( u splitu Requirementu parseu specsu ValueErroru extrasu MODULEu rstripu strip( u clsu srcu distu attrsu extrasu nameu valueu req( ( u2 /tmp/pip-zej_zi-build/pip/_vendor/pkg_resources.pyu parse6 s& u EntryPoint.parsec C s� t | � s t d | � � n i } xZ t | � D]L } | j | | � } | j | k rp t d | | j � � n | | | j <q1 W| S( u Parse an entry point groupu Invalid group nameu Duplicate entry point( u MODULEu ValueErroru yield_linesu parseu name( u clsu groupu linesu distu thisu lineu ep( ( u2 /tmp/pip-zej_zi-build/pip/_vendor/pkg_resources.pyu parse_groupV s u EntryPoint.parse_groupc C s� t | t � r | j � } n t | � } i } x~ | D]v \ } } | d k rj | s[ q7 n t d � � n | j � } | | k r� t d | � � n | j | | | � | | <q7 W| S( u!
