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( t urlparset urlunparse( t ImmutableSetc C s | j � S( N( t next( t o( ( s1 /usr/lib/python2.7/site-packages/pkg_resources.pyt <lambda> s ( t StringIOc B sc | d k rB e j d � } | j } | d k r< | j } n ~ n | d k rW | } n d d Ud S( Ni s exec code in globs, locs( t Nonet syst _getframet f_globalst f_locals( t codet globst locst frame( ( s1 /usr/lib/python2.7/site-packages/pkg_resources.pyt exec_ s ( t BytesIOt execc C sY | d k r t � } n | d k r- | } n t t t | � j � | d � | | � d S( NR ( R t globalsR t compilet opent read( t fnR R ( ( s1 /usr/lib/python2.7/site-packages/pkg_resources.pyt execfile. s ( t utime( t mkdirt renamet unlink( R ( t isdirt spliti t cpythoni� c C s^ t s t d � � n t | � \ } } | rZ | rZ t | � rZ t | � t | | � n d S( Ns* "os.mkdir" not supported on this platform.( t WRITE_SUPPORTt IOErrorR R t _bypass_ensure_directoryR ( t namet modet dirnamet filename( ( s1 /usr/lib/python2.7/site-packages/pkg_resources.pyR" N s c K s> t � } x. | j � D] \ } } | | | <| t | <q Wd S( N( R t itemst _state_vars( t vartypet kwt gR# t val( ( s1 /usr/lib/python2.7/site-packages/pkg_resources.pyt _declare_stateZ s c C sL i } t � } x6 t j � D]( \ } } | d | | | � | | <q W| S( Nt _sget_( R R( R' ( t stateR+ t kt v( ( s1 /usr/lib/python2.7/site-packages/pkg_resources.pyt __getstate__` s c C sJ t � } x: | j � D], \ } } | d t | | | | | � q W| S( Nt _sset_( R R' R( ( R/ R+ R0 R1 ( ( s1 /usr/lib/python2.7/site-packages/pkg_resources.pyt __setstate__g s $c C s | j � S( N( t copy( R, ( ( s1 /usr/lib/python2.7/site-packages/pkg_resources.pyt _sget_dictm s c C s | j � | j | � d S( N( t cleart update( t keyt obR/ ( ( s1 /usr/lib/python2.7/site-packages/pkg_resources.pyt _sset_dictp s c C s | j � S( N( R2 ( R, ( ( s1 /usr/lib/python2.7/site-packages/pkg_resources.pyt _sget_objectt s c C s | j | � d S( N( R4 ( R9 R: R/ ( ( s1 /usr/lib/python2.7/site-packages/pkg_resources.pyt _sset_objectw s c G s d S( N( R ( t args( ( s1 /usr/lib/python2.7/site-packages/pkg_resources.pyR z s c C s{ t � } t j | � } | d k rw t j d k rw y- d d j t � d � | j d � f } Wqw t k rs qw Xn | S( sZ 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.

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 `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.

Resources are extracted to subdirectories of this path based upon information given by the ``IResourceProvider``. You may set this to a temporary directory, but then you must call ``cleanup_resources()`` to delete the extracted files when done. There is no guarantee that ``cleanup_resources()`` will be able to remove all extracted files.

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.
