Description: Introduction
        =============
        This Yet-Another-Mechanize implementation aims to give the developper those new
        features:
        
        - It can be proxified
        - It fakes user agent ``by default``
        - It does not handle robots ``by default``
        
        TODO
        =====
        - lxml integration, maybe steal z3c.etestbrowser
        
        
        Tests and Handbook
        ======================
        
        First, we need to instantiate the sources where we come from::
        
        >>> import BaseHTTPServer
        >>> from SimpleHTTPServer import SimpleHTTPRequestHandler
        >>> from collective.anonymousbrowser.browser import Browser, FF2_USERAGENT
        >>> from threading import Thread
        
        Run a basic request printers to check user agent and further requests::
        
        >>> class ReqHandler(SimpleHTTPRequestHandler):
        ...     def do_GET(self):
        ...         self.end_headers()
        ...         self.send_response(200, '\n\n<html>%s</html>' % self.headers)
        >>> httpd  =  BaseHTTPServer.HTTPServer(('', 45678,) , ReqHandler)
        >>> httpd1 =  BaseHTTPServer.HTTPServer(('', 45679,) , ReqHandler)
        >>> httpd2 =  BaseHTTPServer.HTTPServer(('', 45677,) , ReqHandler)
        >>> httpd3 =  BaseHTTPServer.HTTPServer(('', 45676,) , ReqHandler)
        >>> httpd4 =  BaseHTTPServer.HTTPServer(('', 45675,) , ReqHandler)
        >>> for item in (httpd, httpd1, httpd2, httpd3, httpd4):
        ...      t = Thread(target=item.serve_forever)
        ...      t.setDaemon(True)
        ...      t.start()
        
        User Agent
        ------------
        Oh, my god, we have a brand new user agent by default::
        
        >>> br = Browser()
        ...  we can have the output from the config creation there
        >>> br.open('http://localhost:45678')
        >>> FF2_USERAGENT in br.contents
        True
        >>> br2 = Browser('http://localhost:45678')
        >>> FF2_USERAGENT in br2.contents
        True
        
        
        Proxy mode
        ------------
        But, we want to be anonymous, and we ll set a proxy
        To define those proxies, just just a config.ini file like::
        
        [collective.anonymousbrowser]
        proxies =
        host1:port
        host2:port
        
        When the browser has many proxies defined, it will circly through those ones.
        But, it will not use the same host indefinitivly, just set the ``proxy_max_use`` argument::
        
        >>> from StringIO import StringIO
        >>> from tempfile import mkstemp
        >>> __, config = mkstemp()
        >>> open(config, 'w').write("""[collective.anonymousbrowser]
        ... proxies =
        ...     127.0.0.1:45675
        ...     127.0.0.1:45676
        ...     127.0.0.1:45677
        ...     127.0.0.1:45678
        ...     127.0.0.1:45679
        ...     """)
        >>> b = Browser(config=config)
        >>> b._config._sections
        {'collective.anonymousbrowser': {'__name__': 'collective.anonymousbrowser', 'proxies': '\n127.0.0.1:45675\n127.0.0.1:45676\n127.0.0.1:45677\n127.0.0.1:45678\n127.0.0.1:45679'}}
        >>> b.proxies
        ['127.0.0.1:45675', '127.0.0.1:45676', '127.0.0.1:45677', '127.0.0.1:45678', '127.0.0.1:45679']
        >>> b.proxified
        True
        >>> b.open('http://localhost:45678')
        >>> 'Host: localhost:45678' in b.contents
        True
        >>> b._lastproxy['count'] == 1 and b._lastproxy['proxy'] in [0,1,2,3,4]
        True
        
        We can have a normal unproxified browser too ::
        
        >>> b1 = Browser(proxify=False)
        >>> b1.proxified
        False
        
        Next thing to verify is that we have our pseudo-random loop running
        First thing is we will choose 2 times the 2nd proxy, then the third
        And of course, we will set the mocker to change the proxy at each row.::
        
        >>> import mocker
        >>> import random
        >>> mocked = mocker.Mocker()
        >>> custom_random_int = mocked.replace('random.randint')
        >>> custom_random_int(0, 4)
        <mocker.Mock ...
        >>> mocked.result(2)
        >>> custom_random_int(0,1)
        <mocker.Mock ...
        >>> mocked.result(0)
        >>> custom_random_int(0, 4)
        <mocker.Mock ...
        >>> mocked.result(2)
        >>> custom_random_int(0,1)
        <mocker.Mock ...
        >>> mocked.result(0)
        >>> custom_random_int(0, 4)
        <mocker.Mock ...
        >>> mocked.result(2)
        >>> custom_random_int(0,1)
        <mocker.Mock ...
        >>> mocked.result(0)
        >>> custom_random_int(0, 4)
        <mocker.Mock ...
        >>> mocked.result(3)
        >>> custom_random_int(0,1)
        <mocker.Mock ...
        >>> mocked.result(0)
        >>> custom_random_int(0, 4)
        <mocker.Mock ...
        >>> mocked.result(4)
        >>> custom_random_int(0,1)
        <mocker.Mock ...
        >>> mocked.result(0)
        >>> custom_random_int(0, 4)
        <mocker.Mock ...
        >>> mocked.result(2)
        >>> custom_random_int(0,1)
        <mocker.Mock ...
        >>> mocked.result(0)
        >>> custom_random_int(0, 4)
        <mocker.Mock ...
        >>> mocked.result(1)
        >>> custom_random_int(0,1)
        <mocker.Mock ...
        >>> mocked.result(0)
        >>> mocked.replay()
        >>> b = Browser('http://localhost:45678', config=config)
        >>> b.open('http://localhost:45678')
        >>> b._lastproxy
        {'count': 1, 'proxy': 2}
        >>> b.open('http://localhost:45678')
        >>> b._lastproxy
        {'count': 2, 'proxy': 2}
        >>> b.open('http://localhost:45678')
        >>> b._lastproxy
        {'count': 3, 'proxy': 2}
        >>> b.open('http://localhost:45678')
        >>> b._lastproxy
        {'count': 1, 'proxy': 0}
        >>> b.open('http://localhost:45678')
        >>> b._lastproxy
        {'count': 1, 'proxy': 3}
        >>> b.open('http://localhost:45678')
        >>> b._lastproxy
        {'count': 1, 'proxy': 4}
        >>> b.open('http://localhost:45678')
        >>> b._lastproxy
        {'count': 1, 'proxy': 2}
        >>> b.open('http://localhost:45678')
        >>> b._lastproxy
        {'count': 1, 'proxy': 1}
        >>> mocked.restore()
        
        If the proxies are dead, we remove them from the list::
        
        >>> __, config = mkstemp()
        >>> open(config, 'w').write("""[collective.anonymousbrowser]
        ... proxies =

        ...     127.0.0.1:35676
        ...     127.0.0.1:35677
        ...     127.0.0.1:45678
        ...     """)
        >>> mybrowser = Browser(config=config)
        >>> mybrowser.proxies
        ['127.0.0.1:35675', '127.0.0.1:35676', '127.0.0.1:35677', '127.0.0.1:45678']
        >>> mybrowser.open('http://localhost:45678')
        >>> mybrowser.proxies
        ['127.0.0.1:45678']
        >>> mybrowser.proxies = ['127.0.0.1:34785']
        >>> mybrowser.open('http://localhost:45678')
        Traceback (most recent call last):
        ...
        Exception: There are no valid proxies left
        
        
        The loop is recursion protected. If we return always the same host, so the chooser cannot choose anything else.
        It will loop until it crashes or it handle the recursion::
        
        >>> def randomint(a,b):
        ...     return 2
        >>> import random; random.randint = randomint
        >>> b2 = Browser(config=config)
        >>> b2.proxy_max_use
        3
        >>> b2._lastproxy['count']
        0
        >>> b2.chooseProxy()
        '...
        >>> b2._lastproxy['count']
        1
        >>> b2.chooseProxy()
        '...
        >>> b2._lastproxy['count']
        2
        >>> b2.chooseProxy()
        '...
        >>> b2._lastproxy['count']
        3
        >>> b2.chooseProxy()
        '...
        >>> b2.chooseProxy()
        Ho, seems we got the max wills to choose, something has gone wrong
