Because of the automatic import, this is no longer necessary (but code that does it still works). This will append site-specific paths to the module search path. On Unix (including Mac OSX), it starts with sys.prefix and sys.exec_prefix (if different) and appends lib/python<version>/site-packages as well as lib/site-python. On other platforms (such as Windows), it tries each of the prefixes directly, as well as with lib/site-packages appended. The resulting directories, if they exist, are appended to sys.path, and also inspected for path configuration files. For Debian and derivatives, this sys.path is augmented with directories for packages distributed within the distribution. Local addons go into /usr/local/lib/python<version>/dist-packages, Debian addons install into /usr/{lib,share}/python<version>/dist-packages. /usr/lib/python<version>/site-packages is not used. A path configuration file is a file whose name has the form <package>.pth; its contents are additional directories (one per line) to be added to sys.path. Non-existing directories (or non-directories) are never added to sys.path; no directory is added to sys.path more than once. Blank lines and lines beginning with '#' are skipped. Lines starting with 'import' are executed. For example, suppose sys.prefix and sys.exec_prefix are set to /usr/local and there is a directory /usr/local/lib/python2.5/site-packages with three subdirectories, foo, bar and spam, and two path configuration files, foo.pth and bar.pth. Assume foo.pth contains the following: # foo package configuration foo bar bletch and bar.pth contains: # bar package configuration bar Then the following directories are added to sys.path, in this order: /usr/local/lib/python2.5/site-packages/bar /usr/local/lib/python2.5/site-packages/foo Note that bletch is omitted because it doesn't exist; bar precedes foo because bar.pth comes alphabetically before foo.pth; and spam is omitted because it is not mentioned in either path configuration file. After these path manipulations, an attempt is made to import a module named sitecustomize, which can perform arbitrary additional site-specific customizations. If this import fails with an ImportError exception, it is silently ignored. i����Nc G sR t j j | � } y t j j | � } Wn t k r; n X| t j j | � f S( N( t ost patht joint abspatht OSErrort normcase( t pathst dir( ( s /usr/lib/python2.7/site.pyt makepathU s c C si xb t j j � D]Q } t | d � r+ q n y t j j | j � | _ Wq t t f k r` q Xq Wd S( s6 Set all module' __file__ attribute to an absolute patht __loader__N( t syst modulest valuest hasattrR R R t __file__t AttributeErrorR ( t m( ( s /usr/lib/python2.7/site.pyt abs__file__^ s c C sl g } t � } xL t j D]A } t | � \ } } | | k r | j | � | j | � q q W| t j (| S( sK Remove duplicate entries from sys.path along with making them absolute( t setR R R t appendt add( t Lt known_pathsR t dircase( ( s /usr/lib/python2.7/site.pyt removeduppathsi s c C sp t � } x` t j D]U } y8 t j j | � rP t | � \ } } | j | � n Wq t k rg q q Xq W| S( sD Return a set containing all existing directory entries from sys.path( R R R R t isdirR R t TypeError( t dR R ( ( s /usr/lib/python2.7/site.pyt _init_pathinfo| s c B s� | d k r e � d } n d } e j j | | � } y e | d � } Wn e k r^ d SX| �@x8e | � D]*\ } } | j d � r� qs n y� | j d � r� | d Uws n | j � } e | | � \ } } | | k re j j | � re j j | � | j | � n Wqs e k r�} e j d j | d | � IJxE e j e j � � D]. } x% | j � D] } e j d | IJqlWqYWe j d IJPqs Xqs WWd QX| r�d } n | S( s� Process a .pth file within the site-packages directory: For each line in the file, either combine it with sitedir to a path and add that to known_paths, or execute it if it starts with 'import '. i i t rUNt #s import s import s" Error processing line {:d} of {}: s s Remainder of file ignored( s import s import ( t NoneR R R R t opent IOErrort enumeratet startswitht rstripR t existsR R R t Exceptiont stderrt formatt tracebackt format_exceptiont exc_infot splitlines( t sitedirt nameR t resett fullnamet ft nt lineR R t errt record( ( s /usr/lib/python2.7/site.pyt addpackage� sB c C s� | d k r t � } d } n d } t | � \ } } | | k rU t j j | � n y t j | � } Wn t j k r d SXt j d } g | D] } | j | � r� | ^ q� } x$ t | � D] } t | | | � q� W| r� d } n | S( sT Add 'sitedir' argument to sys.path if missing and handle .pth files in 'sitedir'i i Nt pth( R R R R R R R t listdirt errort extsept endswitht sortedR6 ( R- R R/ t sitedircaset namest dotpthR.
