The change to use the newer httplib interface admitted the possibility
that we'd get an HTTP/1.1 chunked response, but the code didn't handle
it correctly. The raw socket object can't be pass to addinfourl(),
because it would read the undecoded response. Instead, addinfourl()
must call HTTPResponse.read(), which will handle the decoding.
One extra wrinkle is that the HTTPReponse object can't be passed to
addinfourl() either, because it doesn't implement readline() or
readlines(). As a quick hack, use socket._fileobject(), which
implements those methods on top of a read buffer. (suggested by mwh)
Finally, add some tests based on test_urllibnet.
Thanks to Andrew Sawyers for originally reporting the chunked problem.
Invoke the standard error handlers for non-200 responses.
Always supply a "Connection: close" header to prevent the server from
leaving the connection open. Downstream users of the socket may
attempt recv()/read() with no arguments, which would block if the
connection were kept open.
John J. Lee writes: "the patch makes it possible to implement
functionality like HTTP cookie handling, Refresh handling,
etc. etc. using handler objects. At the moment urllib2's handler
objects aren't quite up to the job, which results in a lot of
cut-n-paste and subclassing. I believe the changes are
backwards-compatible, with the exception of people who've
reimplemented build_opener()'s functionality -- those people would
need to call opener.add_handler(HTTPErrorProcessor).
The main change is allowing handlers to implement
methods like:
http_request(request)
http_response(request, response)
In addition to the usual
http_open(request)
http_error{_*}(...)
"
Note that the change isn't well documented at least in part because
handlers aren't well documented at all. Need to fix this.
Add a bunch of new tests. It appears that none of these tests
actually use the network, so they don't need to be guarded by a
resource flag.
imports e.g. test_support must do so using an absolute package name
such as "import test.test_support" or "from test import test_support".
This also updates the README in Lib/test, and gets rid of the
duplicate data dirctory in Lib/test/data (replaced by
Lib/email/test/data).
Now Tim and Jack can have at it. :)
