"""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

TODO: (here and __init__)
* search based on label, review, or other annotations (possible?)
* edit (specifically, Put requests) seem to fail effect a change
Problems With API:
* Adding a book with a review to the library adds a note, not a review.
This does not get included in the returned item. You see this by
looking at My Library through the website.
* Editing a review never edits a review (unless it is freshly added, but
see above). More generally,
* a Put request with changed annotations (label/rating/review) does NOT
change the data. Note: Put requests only work on the href from
GetEditLink (as per the spec). Do not try to PUT to the annotate or
library feeds, this will cause a 400 Invalid URI Bad Request response.
Attempting to Post to one of the feeds with the updated annotations
does not update them. See the following for (hopefully) a follow up:
google.com/support/forum/p/booksearch-apis/thread?tid=27fd7f68de438fc8
* Attempts to workaround the edit problem continue to fail. For example,
removing the item, editing the data, readding the item, gives us only
our originally added data (annotations). This occurs even if we
completely shut python down, refetch the book from the public feed,
and re-add it. There is some kind of persistence going on that I
cannot change. This is likely due to the annotations being cached in
the annotation feed and the inability to edit (see Put, above)
* GetAnnotationLink has www.books.... as the server, but hitting www...
results in a bad URI error.
* Spec indicates there may be multiple labels, but there does not seem
to be a way to get the server to accept multiple labels, nor does the
web interface have an obvious way to have multiple labels. Multiple
labels are never returned.

If the handshake completes without raising an exception, then a TLS

connection as if it were a socket.
This class provides both synchronous and asynchronous versions of
its key functions. The synchronous versions should be used when
writing single-or multi-threaded code using blocking sockets. The
asynchronous versions should be used when performing asynchronous,
event-based I/O with non-blocking sockets.
Asynchronous I/O is a complicated subject; typically, you should
not use the asynchronous functions directly, but should use some
framework like asyncore or Twisted which TLS Lite integrates with

associated with usernames. If the client performs a
shared-key handshake, the session's sharedKeyUsername
attribute will be set.

requests server certificate authentication.

@param reqCert: Whether to request client certificate
authentication. This only applies if the client chooses server
certificate authentication; if the client chooses SRP or
shared-key authentication, this will be ignored. If the client
performs a client certificate authentication, the sessions's
clientCertChain attribute will be set.

The client can resume sessions from this cache. Alternatively,
if the client performs a full handshake, a new session will be

the ciphersuites and SSL/TLS version chosen by the server.

@type session: L{tlslite.Session.Session}
@ivar session: The session corresponding to this connection.
Due to TLS session resumption, multiple connections can correspond
to the same underlying session.
@type version: tuple
@ivar version: The TLS version being used for this connection.
(3,0) means SSL 3.0, and (3,1) means TLS 1.0.
@type closed: bool
@ivar closed: If this connection is closed.
@type resumed: bool
@ivar resumed: If this connection is based on a resumed session.
@type allegedSharedKeyUsername: str or None
@ivar allegedSharedKeyUsername: This is set to the shared-key
username asserted by the client, whether the handshake succeeded or
not. If the handshake fails, this can be inspected to
determine if a guessing attack is in progress against a particular
user account.
@type allegedSrpUsername: str or None
@ivar allegedSrpUsername: This is set to the SRP username
asserted by the client, whether the handshake succeeded or not.
If the handshake fails, this can be inspected to determine
if a guessing attack is in progress against a particular user
account.
@type closeSocket: bool
@ivar closeSocket: If the socket should be closed when the
connection is closed (writable).
If you set this to True, TLS Lite will assume the responsibility of
closing the socket when the TLS Connection is shutdown (either
through an error or through the user calling close()). The default
is False.
@type ignoreAbruptClose: bool
@ivar ignoreAbruptClose: If an abrupt close of the socket should
raise an error (writable).
If you set this to True, TLS Lite will not raise a
L{tlslite.errors.TLSAbruptCloseError} exception if the underlying
socket is unexpectedly closed. Such an unexpected closure could be
caused by an attacker. However, it also occurs with some incorrect
TLS implementations.
You should set this to True only if you're not worried about an
attacker truncating the connection, and only if necessary to avoid
spurious errors. The default is False.

"""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()
x509.parse(s)

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.
