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. 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) /opt/alt/python27/lib64/python2.7/site.pyt makepathO 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) /opt/alt/python27/lib64/python2.7/site.pyt abs__file__X 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) /opt/alt/python27/lib64/python2.7/site.pyt removeduppathsc 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) /opt/alt/python27/lib64/python2.7/site.pyt _init_pathinfov 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) /opt/alt/python27/lib64/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.
