Core and Builtins

- Issue #10221: dict.pop(k) now has a key error message that includes the
missing key (same message d[k] returns for missing keys).

``file.writelines()`` closes the file.

- Issue #7616: Fix copying of overlapping memoryview slices with the Intel

- Issue #9948: Fixed problem of losing filename case information.

- Issue #10004: quoprimime no longer generates a traceback when confronted
with invalid characters after '=' in a Q-encoded word.

- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
received. Now sendall() properly calls signal handlers if necessary,
and retries sending if these returned successfully, including on sockets
with a timeout.

ZipFile.open()) could return more bytes than requested.

- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
This prevents user-created self-referencing ordered dictionaries from
becoming permanently uncollectable GC garbage. The downside is that
removing __del__ means that the internal doubly-linked list has to wait for
GC collection rather than freeing memory immediately when the refcnt drops
to zero.

- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
different internal state for small values of n. Fixed by salting the

- Issue #9792: In case of connection failure, socket.create_connection()
would swallow the exception and raise a new one, making it impossible
to fetch the original errno, or to filter timeout errors. Now the
original error is re-raised.

- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
be updated back after the system call. Original patch by Brian Brazil.

dict types. Patch by Michele Orr and Bjrn Lindqvist.

- Issue #7005: Fixed output of None values for RawConfigParser.write and

avoid issues when socket.close is called from a __del__ method.

can be set to False to turn off the previously undocumented 'popularity'
heuristic. Patch by Terry Reedy and Eli Bendersky

- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
falling into recursion.

- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four

reflexive operations, namely x -= x and x ^= x.

- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing
error handling when accepting a new connection.

- Issue #658749: asyncore's connect() method now correctly interprets winsock

- Issue #9501: Fixed logging regressions in cleanup code.

- Issue #9214: Set operations on KeysView or ItemsView in the collections
module now correctly return a set. (Patch by Eli Bendersky.)

- Issue #9617: Signals received during a low-level write operation aren't
ignored by the buffered IO layer anymore.

- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
are not held onto after they are deleted elsewhere.

- Issue #9626: the view methods for collections.OrderedDict() were returning
the unordered versions inherited from dict. Those methods are now
overridden to provide ordered views.

- Issue #8688: MANIFEST files created by distutils now include a magic
comment indicating they are generated. Manually maintained MANIFESTs
without this marker will not be overwritten or removed.

- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
and a BadZipfile error is raised if it doesn't match (as used to be the
case in Python 2.5 and earlier).

- Issue #9550: a BufferedReader could issue an additional read when the
original read request had been satisfied, which could block indefinitely
when the underlying raw IO channel was e.g. a socket. Report and original
patch by Jason V. Miller.

- Issue #9551: Don't raise TypeError when setting the value to None for
SafeConfigParser instances constructed with allow_no_value == True.

- Issue #6915: Under Windows, os.listdir() didn't release the Global
Interpreter Lock around all system calls. Original patch by Ryan Kelly.

- Issue #3757: thread-local objects now support cyclic garbage collection.
Thread-local objects involved in reference cycles will be deallocated
timely by the cyclic GC, even if the underlying thread is still running.

- Issue #6231: Fix xml.etree.ElementInclude to include the tail of the
current node.

- Issue #6869: Fix a refcount problem in the _ctypes extension.

- Issue5504 - ctypes should now work with systems where mmap can't be

encoded word encoded in base64 is lacking padding.

XML-RPC request.

- Issue #5542: Remove special logic that closes HTTPConnection socket on EPIPE.
