against a SimpleXMLRPCServer in a separate thread.  Because of
problems with WSAEWOULDBLOCK (error 10035) being raised by the server
on Windows, these new tests are skipped on win32. [GSoC - Alan McIntyre]

test.test_support.catch_warning is more full-featured and provides the same
functionality.

Since guard_warnings_filter was added in 2.6 there is no
backwards-compatibility issues.

in PythonCmd().

Fixes #1730114.

The value is always written to the returned pointer if getting it was
successful, even if a warning causes an error. (This probably doesn't matter
as the caller will probably discard the value.)

Will backport.

GB18030 extension in encoding. (bug reported by Bjorn Stabell)

DebuggingServerTests, construct SMTP objects with a localhost argument
to avoid abysmally long FQDN lookups (not relevant to items under
test) on some machines that would cause the test to fail. Moved server
setup code in the server function inside the try block to avoid the
possibility of setup failure hanging the test.  Minor edits to conform
to PEP 8. [GSoC - Alan McIntyre]

overrides asyncore.dispatcher.handle_expt to do nothing, since
select.poll gives a POLLHUP error at the completion of these tests.
Added timeout & count arguments to several asyncore.loop calls to
avoid the possibility of a test hanging up a build. [GSoC - Alan

Resolves patch 1761803.

find_prefix_at_end function. Check behavior of a string given as a
producer.  Added tests for behavior of asynchat.async_chat when given
int, long, and None terminator arguments. Added usepoll attribute to
TestAsynchat to allow running the asynchat tests with poll support
chosen whether it's available or not (improves coverage of asyncore
code). [GSoC - Alan McIntyre]

so that the event gets set if a failure occurs during server setup
(otherwise the test will block forever).  Changed to let the OS assign
the server port number, and client side of test waits for port number
assignment before proceeding. The test data in DispatcherWithSendTests
is also sent in multiple send() calls instead of one to make sure this
works properly. [GSoC - Alan McIntyre]
