What's New in Python 2.7.1 release candidate 1?
===============================================

*Release date: 2010-11-13*

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).

- Issue #10125: Don't segfault when the iterator passed to
``file.writelines()`` closes the file.

- Issue #10186: Fix the SyntaxError caret when the offset is equal to the
length of the offending line.

- Issue #9997: Don't let the name "top" have special significance in scope
resolution.

- Issue #9862: Compensate for broken PIPE_BUF in AIX by hard coding
its value as the default 512 when compiling on AIX.

- Issue #9675: CObject use is marked as a Py3k warning, not a deprecation
warning.

long for a class whose __long__ method returns a plain int. This
fixes an interpreter crash when initializing an instance of a long
subclass from an object whose __long__ method returns a plain int.

- Issue #10006: type.__abstractmethods__ now raises an AttributeError.

- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
thread-local storage key.

encoding and errors attributes instead of using utf-8 in strict mode, to get
the same behaviour than the print statement.

a memoryview object.

- Restore GIL in nis_cat in case of error.

- Issue #9688: __basicsize__ and __itemsize__ must be accessed as Py_ssize_t.

- format(complex(0.0, 2.0), '-') included a sign and parentheses.

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

Library
-------

- Issue 9926: Wrapped TestSuite subclass does not get __call__ executed

EWOULDBLOCK/ECONNABORTED on incomplete connection attempt but returns None
instead.

for append that isn't seekable. Patch by Brian Brazil.

- Issue #6105: json.dumps now respects OrderedDict's iteration order.

- Issue #9295: Fix a crash under Windows when calling close() on a file
object with custom buffering from two threads at once.

end of the "file" in cStringIO.

- 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.

- Issue #9947: logging: Fixed locking bug in stopListening.

- Issue #9945: logging: Fixed locking bugs in addHandler/removeHandler.

- Issue #9936: Fixed executable lines' search in the trace module.

handles non-blocking readinto() returning None correctly.

- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
SSLSocket.sendto() to match the corresponding socket methods. Also,
fix various SSLSocket methods to raise socket.error rather than an
unhelpful TypeError when called on an unconnected socket. Original patch
by Andrew Bennetts.

values: d['x'] = d.

- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X.

- Issue #9837: The read() method of ZipExtFile objects (as returned by
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
value.

- 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.

- Issue #1100562: Fix deep-copying of objects derived from the list and
dict types. Patch by Michele Orr and Bjrn Lindqvist.

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

- Issue #808164: Fixed socket.close to avoid references to globals, to
avoid issues when socket.close is called from a __del__ method.

- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which
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
character years even if the message contains RFC822 two character years.

- Issue #8750: Fixed MutableSet's methods to correctly handle
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
errors.

- 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
PROT_WRITE and PROT_EXEC.

- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
This is how it is supposed to work, wget and curl do the same. Previous
behavior was wrong.

- Issue #2944: asyncore doesn't handle connection refused correctly.

- Issue #3196: email header decoding is now forgiving if an RFC2047
encoded word encoded in base64 is lacking padding.

- Issue #9444: Argparse now uses the first element of prefix_chars as

the command line.

regular expressions.

entries, consider the first one.

- Issue #8397: Raise an error when attempting to mix iteration and regular
reads on a BZ2File object, rather than returning incorrect results.

- Issue #5294: Fix the behavior of pdb's "continue" command when called
in the top-level debugged frame.

- Issue #5727: Restore the ability to use readline when calling into pdb
in doctests.

- Issue #6719: In pdb, do not stop somewhere in the encodings machinery

utf-16 incremental encoders.

- Issue #7113: Speed up loading in ConfigParser. Patch by ukasz Langa.

- Issue #3704: cookielib was not properly handling URLs with a / in the
parameters.

- Issue #9032: XML-RPC client retries the request on EPIPE error. The EPIPE
error occurs when the server closes the socket and the client sends a big
XML-RPC request.

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

- Issue #4629: getopt raises an error if an argument ends with = whereas getopt
doesn't except a value (eg. --help= is rejected if getopt uses ['help='] long
options).

- Issue #7895: platform.mac_ver() no longer crashes after calling os.fork()
