"""This file implements the chaffing algorithm.
Winnowing and chaffing is a technique for enhancing privacy without requiring
strong encryption. In short, the technique takes a set of authenticated
message blocks (the wheat) and adds a number of chaff blocks which have
randomly chosen data and MAC fields. This means that to an adversary, the
chaff blocks look as valid as the wheat blocks, and so the authentication
would have to be performed on every block. By tailoring the number of chaff
blocks added to the message, the sender can make breaking the message
computationally infeasible. There are many other interesting properties of
the winnow/chaff technique.
For example, say Alice is sending a message to Bob. She packetizes the
message and performs an all-or-nothing transformation on the packets. Then
she authenticates each packet with a message authentication code (MAC). The
MAC is a hash of the data packet, and there is a secret key which she must
share with Bob (key distribution is an exercise left to the reader). She then
adds a serial number to each packet, and sends the packets to Bob.
Bob receives the packets, and using the shared secret authentication key,
authenticates the MACs for each packet. Those packets that have bad MACs are
simply discarded. The remainder are sorted by serial number, and passed
through the reverse all-or-nothing transform. The transform means that an
eavesdropper (say Eve) must acquire all the packets before any of the data can
be read. If even one packet is missing, the data is useless.
There's one twist: by adding chaff packets, Alice and Bob can make Eve's job
much harder, since Eve now has to break the shared secret key, or try every
combination of wheat and chaff packet to read any of the message. The cool
thing is that Bob doesn't need to add any additional code; the chaff packets
are already filtered out because their MACs don't match (in all likelihood --
since the data and MACs for the chaff packets are randomly chosen it is
possible, but very unlikely that a chaff MAC will match the chaff data). And
Alice need not even be the party adding the chaff! She could be completely
unaware that a third party, say Charles, is adding chaff packets to her
messages as they are transmitted.
For more information on winnowing and chaffing see this paper:

The implementation here is similar to the one in PGP. To be
cryptographically strong, it must be difficult to determine the RNG's
output, whether in the future or the past. This is done by using
a cryptographic hash function to "stir" the random data.
Entropy is gathered in the same fashion as PGP; the highest-resolution
clock around is read and the data is added to the random number pool.
A conservative estimate of the entropy is then kept.
If a cryptographically secure random source is available (/dev/urandom
on many Unixes, Windows CryptGenRandom on most Windows), then use
it.
Instance Attributes:
bits : int
Maximum size of pool in bits
bytes : int
Maximum size of pool in bytes
entropy : int

Attributes:
vq: The vq parameter, which is only supported for video feeds, specifies a
search query term. Refer to API documentation for further details.
orderby: The orderby parameter, which is only supported for video feeds,
specifies the value that will be used to sort videos in the search
result set. Valid values for this parameter are relevance, published,
viewCount and rating.
time: The time parameter, which is only available for the top_rated,
top_favorites, most_viewed, most_discussed, most_linked and
most_responded standard feeds, restricts the search to videos uploaded
within the specified time. Valid values for this parameter are today
(1 day), this_week (7 days), this_month (1 month) and all_time.
The default value for this parameter is all_time.
format: The format parameter specifies that videos must be available in a
particular video format. Refer to the API documentation for details.
racy: The racy parameter allows a search result set to include restricted
content as well as standard content. Valid values for this parameter
are include and exclude. By default, restricted content is excluded.
lr: The lr parameter restricts the search to videos that have a title,
description or keywords in a specific language. Valid values for the lr
parameter are ISO 639-1 two-letter language codes.
restriction: The restriction parameter identifies the IP address that
should be used to filter videos that can only be played in specific
countries.
location: A string of geo coordinates. Note that this is not used when the
search is performed but rather to filter the returned videos for ones
that match to the location entered.

"""Provides HTTP functions for gdata.service to use on Google App Engine
AppEngineHttpClient: Provides an HTTP request method which uses App Engine's
urlfetch API. Set the http_client member of a GDataService object to an
instance of an AppEngineHttpClient to allow the gdata library to run on
Google App Engine.
run_on_appengine: Function which will modify an existing GDataService object
to allow it to run on App Engine. It works by creating a new instance of
the AppEngineHttpClient and replacing the GDataService object's
http_client.
HttpRequest: Function that wraps google.appengine.api.urlfetch.Fetch in a
common interface which is used by gdata.service.GDataService. In other
words, this module can be used as the gdata service request handler so
that all HTTP requests will be performed by the hosting Google App Engine
server.

This class is currently experimental and may change in backwards
incompatible ways.
This class exists to simplify the following three areas involved in using
the Google Data APIs.
CRUD Operations:
The client provides a generic 'request' method for making HTTP requests.
There are a number of convenience methods which are built on top of
request, which include get_feed, get_entry, get_next, post, update, and
delete. These methods contact the Google Data servers.
Auth:
Reading user-specific private data requires authorization from the user as
do any changes to user data. An auth_token object can be passed into any
of the HTTP requests to set the Authorization header in the request.
You may also want to set the auth_token member to a an object which can
use modify_request to set the Authorization header in the HTTP request.
If you are authenticating using the email address and password, you can
use the client_login method to obtain an auth token and set the
auth_token member.
If you are using browser redirects, specifically AuthSub, you will want
to use gdata.gauth.AuthSubToken.from_url to obtain the token after the
redirect, and you will probably want to updgrade this since use token
to a multiple use (session) token using the upgrade_token method.
API Versions:
This client is multi-version capable and can be used with Google Data API
version 1 and version 2. The version should be specified by setting the
api_version member to a string, either '1' or '2'.

See also documentation for atom.client.AtomPubClient.request.
If a 302 redirect is sent from the server to the client, this client

The same request URI and method will be used as in the original request,
but a gsessionid URL parameter will be added to the request URI with
the value provided in the server's 302 redirect response. If the 302
redirect is not in the format specified by the Google Calendar API, a
RedirectError will be raised containing the body of the server's
response.
The method calls the client's modify_request method to make any changes
required by the client before the request is made. For example, a
version 2 client could add a GData-Version: 2 header to the request in
its modify_request method.
Args:
method: str The HTTP verb for this request, usually 'GET', 'POST',
'PUT', or 'DELETE'
uri: atom.http_core.Uri, str, or unicode The URL being requested.

modify_request method. Recommended classes include
gdata.gauth.ClientLoginToken and gdata.gauth.AuthSubToken

http_request: (optional) atom.http_core.HttpRequest
converter: function which takes the body of the response as it's only
argument and returns the desired object.
desired_class: class descended from atom.core.XmlElement to which a
successful response should be converted. If there is no
converter function specified (converter=None) then the
desired_class will be used in calling the
atom.core.parse function. If neither
the desired_class nor the converter is specified, an
HTTP reponse object will be returned.
redirects_remaining: (optional) int, if this number is 0 and the
server sends a 302 redirect, the request method
will raise an exception. This parameter is used in
recursive request calls to avoid an infinite loop.

description of the object's interface) if no converter was

The id_url_string can be used in place of an entry if the batch operation
applies to a URL. For example query and delete operations require just
the URL of an entry, no body is sent in the HTTP request. If an
id_url_string is sent instead of an entry, a BatchEntry is created and
added to the feed.
This method also assigns the desired batch id to the entry so that it
can be referenced in the server's response. If the batch_id_string is
None, this method will assign a batch_id to be the index at which this
entry will be in the feed's entry list.
Args:
entry: BatchEntry, atom.data.Entry, or another Entry flavor (optional)
The entry which will be sent to the server as part of the batch
request. The item must have a valid atom id so that the server
knows which entry this request references.
id_url_string: str (optional) The URL of the entry to be acted on. You
can find this URL in the text member of the atom id for an entry.
If an entry is not sent, this id will be used to construct a new
BatchEntry which will be added to the request feed.
batch_id_string: str (optional) The batch ID to be used to reference
this batch operation in the results feed. If this parameter is None,
the current length of the feed's entry array will be used as a
count. Note that batch_ids should either always be specified or
never, mixing could potentially result in duplicate batch ids.
operation_string: str (optional) The desired batch operation which will
set the batch_operation.type member of the entry. Options are
'insert', 'update', 'delete', and 'query'
Raises:
MissingRequiredParameters: Raised if neither an id_ url_string nor an
entry are provided in the request.
Returns:
The added entry.

"""The gd:recurrence element.
Represents the dates and times when a recurring event takes place.
The string that defines the recurrence consists of a set of properties,
each of which is defined in the iCalendar standard (RFC 2445).
Specifically, the string usually begins with a DTSTART property that
indicates the starting time of the first instance of the event, and
often a DTEND property or a DURATION property to indicate when the
first instance ends. Next come RRULE, RDATE, EXRULE, and/or EXDATE
properties, which collectively define a recurring event and its
exceptions (but see below). (See section 4.8.5 of RFC 2445 for more
information about these recurrence component properties.) Last comes a
VTIMEZONE component, providing detailed timezone rules for any timezone
ID mentioned in the preceding properties.
Google services like Google Calendar don't generally generate EXRULE
and EXDATE properties to represent exceptions to recurring events;
instead, they generate <gd:recurrenceException> elements. However,
Google services may include EXRULE and/or EXDATE properties anyway;
for example, users can import events and exceptions into Calendar, and
if those imported events contain EXRULE or EXDATE properties, then
Calendar will provide those properties when it sends a <gd:recurrence>
element.
Note the the use of <gd:recurrenceException> means that you can't be
sure just from examining a <gd:recurrence> element whether there are
any exceptions to the recurrence description. To ensure that you find
all exceptions, look for <gd:recurrenceException> elements in the feed,
and use their <gd:originalEvent> elements to match them up with
<gd:recurrence> elements.
"""

class RecurrenceException(atom.core.XmlElement):
"""The gd:recurrenceException element.
Represents an event that's an exception to a recurring event-that is,
an instance of a recurring event in which one or more aspects of the
recurring event (such as attendance list, time, or location) have been
changed.
Contains a <gd:originalEvent> element that specifies the original
recurring event that this event is an exception to.
When you change an instance of a recurring event, that instance becomes
an exception. Depending on what change you made to it, the exception
behaves in either of two different ways when the original recurring
event is changed:
- If you add, change, or remove comments, attendees, or attendee
responses, then the exception remains tied to the original event, and
changes to the original event also change the exception.
- If you make any other changes to the exception (such as changing the
time or location) then the instance becomes "specialized," which means
that it's no longer as tightly tied to the original event. If you
change the original event, specialized exceptions don't change. But
see below.
For example, say you have a meeting every Tuesday and Thursday at
2:00 p.m. If you change the attendance list for this Thursday's meeting
(but not for the regularly scheduled meeting), then it becomes an
exception. If you change the time for this Thursday's meeting (but not
for the regularly scheduled meeting), then it becomes specialized.
Regardless of whether an exception is specialized or not, if you do
something that deletes the instance that the exception was derived from,
then the exception is deleted. Note that changing the day or time of a
recurring event deletes all instances, and creates new ones.
For example, after you've specialized this Thursday's meeting, say you
change the recurring meeting to happen on Monday, Wednesday, and Friday.
That change deletes all of the recurring instances of the
Tuesday/Thursday meeting, including the specialized one.
If a particular instance of a recurring event is deleted, then that
instance appears as a <gd:recurrenceException> containing a
<gd:entryLink> that has its <gd:eventStatus> set to
"http://schemas.google.com/g/2005#event.canceled". (For more

This module contains a client and other classes which make working with the
Google Documents List Data API and the Google Spreadsheets Data API look a
bit more like working with a heirarchical database. Using the DatabaseClient,
you can create or find spreadsheets and use them like a database, with
worksheets representing tables and rows representing records.
Example Usage:
# Create a new database, a new table, and add records.

Warnings:
Care should be exercised when using this module on spreadsheets
which contain formulas. This module treats all rows as containing text and
updating a row will overwrite any formula with the output of the formula.
The intended use case is to allow easy storage of text data in a spreadsheet.
Error: Domain specific extension of Exception.
BadCredentials: Error raised is username or password was incorrect.
CaptchaRequired: Raised if a login attempt failed and a CAPTCHA challenge

},

"commentCount": 22,
"favoriteCount": 201
}

},

You would do the following:
x = gdata.core.parse_json(the_above_string)
# Gives you 800
x.data.total_items
# Should be 22
x.data.items[0].comment_count
# The apiVersion is '2.0'
x.api_version
To create a Jsonc object which would produce the above JSON, you would do:
gdata.core.Jsonc(
api_version='2.0',
data=gdata.core.Jsonc(
total_items=800,
items=[
gdata.core.Jsonc(
view_count=220101,
comment_count=22,
favorite_count=201,
content={
'1': ('rtsp://v5.cache3.c.youtube.com'

x.api_version = '2.0'
x.data = gdata.core.Jsonc()
x.data.total_items = 800
x.data.items = []
# etc.
How it works:
The JSON-C data is stored in an internal dictionary (._dict) and the
getattr, setattr, and delattr methods rewrite the name which you provide
to mirror the expected format in JSON-C. (For more details on name
conversion see _to_jsonc_name.) You may also access members using
getitem, setitem, delitem as you would for a dictionary. For example
x.data.total_items is equivalent to x['data']['totalItems']
(Not all dict methods are supported so if you need something other than
the item operations, then you will want to use the ._dict member).
You may need to use getitem or the _dict member to access certain
properties in cases where the JSON-C syntax does not map neatly to Python
objects. For example the YouTube Video feed has some JSON like this:
"content": {"1": "rtsp://v5.cache3.c.youtube.com..."...}
You cannot do x.content.1 in Python, so you would use the getitem as
follows:
x.content['1']
or you could use the _dict member as follows:
x.content._dict['1']
If you need to create a new object with such a mapping you could use.
x.content = gdata.core.Jsonc(_dict={'1': 'rtsp://cache3.c.youtube.com...'})

"""This class can be "mixed in" with an
L{asyncore.dispatcher} to add TLS support.
This class essentially sits between the dispatcher and the select
loop, intercepting events and only calling the dispatcher when
applicable.
In the case of handle_read(), a read operation will be activated,
and when it completes, the bytes will be placed in a buffer where
the dispatcher can retrieve them by calling recv(), and the
dispatcher's handle_read() will be called.
In the case of handle_write(), the dispatcher's handle_write() will
be called, and when it calls send(), a write operation will be
activated.
To use this class, you must combine it with an asyncore.dispatcher,
and pass in a handshake operation with setServerHandshakeOp().
Below is an example of using this class with medusa. This class is
mixed in with http_channel to create http_tls_channel. Note:
1. the mix-in is listed first in the inheritance list
2. the input buffer size must be at least 16K, otherwise the
dispatcher might not read all the bytes from the TLS layer,
leaving some bytes in limbo.
3. IE seems to have a problem receiving a whole HTTP response in a
single TLS record, so HTML pages containing '\\r\\n\\r\\n' won't
be displayed on IE.
Add the following text into 'start_medusa.py', in the 'HTTP Server'
section::
from tlslite.api import *
s = open("./serverX509Cert.pem").read()
x509 = X509()

If the TLS layer raises an exception, the exception will be caught
in asyncore.dispatcher, which will call close() on this class. The
TLS layer always closes the TLS connection before raising an
exception, so the close operation will complete right away, causing
asyncore.dispatcher.close() to be called, which closes the socket
and removes this instance from the asyncore loop.
