Ned Deily657b2de2011-06-28 19:51:30 -0700642- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
643 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
644 interpreter process. This could cause failures in non-Distutils subprocesses
645 and was unreliable since tests or user programs could modify the interpreter
646 environment after Distutils set it. Instead, have Distutils set the the
647 deployment target only in the environment of each build subprocess. It is
648 still possible to globally override the default by setting
649 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
650 greater or equal to the default value, the value with which the interpreter
651 was built.

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002149 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

2492-----------------
2493
Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002494- Issue #10068: Global objects which have reference cycles with their module's
2495 dict are now cleared again. This causes issue #7140 to appear again.
2496
Victor Stinner257d38f2010-10-09 10:12:11 +00002497- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00002498 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00002499
Georg Brandl27a28582010-10-10 09:49:21 +00002500- ast.literal_eval() can now handle negative numbers. It is also a little more
2501 liberal in what it accepts without compromising the safety of the evaluation.
2502 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00002503
Benjamin Peterson970d1882010-10-02 17:55:47 +00002504- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
2505 result metaclasses can now be ABCs (see #9533).
2506
Victor Stinneraef57e32010-10-02 11:50:49 +00002507- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
2508
Victor Stinner5593d8a2010-10-02 11:11:27 +00002509- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00002510 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
2511 32 bits wchar_t (eg. Linux in narrow build).

Victor Stinner137c34c2010-09-29 10:25:54 +00002516- Issue #9979: Create function PyUnicode_AsWideCharString().
2517
Brett Cannon5305a992010-09-27 21:08:38 +00002518- Issue #7397: Mention that importlib.import_module() is probably what someone
2519 really wants to be using in __import__'s docstring.
2520
Georg Brandl27a28582010-10-10 09:49:21 +00002521- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
2522 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +00002523
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002524- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002525 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002526
Brian Curtine8e4b3b2010-09-23 20:04:14 +00002527- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
2528
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002529- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2530 threads are still running. Instead, reinitialize the GIL on a second call to
2531 Py_Initialize().
2532
Georg Brandl27a28582010-10-10 09:49:21 +00002533- All SyntaxErrors now have a column offset and therefore a caret when the error
2534 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00002535
Brett Cannonbc2eff32010-09-19 21:39:02 +00002536- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2537 module that was imported, but instead gets the module from sys.modules.
2538
Nick Coghlan37ee8502010-12-03 14:26:13 +00002539- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00002540 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00002541
Georg Brandl27a28582010-10-10 09:49:21 +00002542- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2543 with a non-empty format string. This is an effort to future-proof user
2544 code. If a derived class does not currently implement __format__ but later
2545 adds its own __format__, it would most likely break user code that had
2546 supplied a format string. This will be changed to a DeprecationWaring in
2547 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002548
Antoine Pitrou1df15362010-09-13 14:16:46 +00002549- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2550 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2551 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2552
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002553- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2554 functions from the libc caused the methods .upper() and lower() to become
2555 locale aware and created subtly wrong results.
2556
Georg Brandl27a28582010-10-10 09:49:21 +00002557- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2558 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002559
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002560- Issue #4617: Previously it was illegal to delete a name from the local
2561 namespace if it occurs as a free variable in a nested block. This limitation
2562 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2563
Georg Brandl27a28582010-10-10 09:49:21 +00002564- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2565 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2566 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2567 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002568
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002569- Issue #9757: memoryview objects get a release() method to release the
2570 underlying buffer (previously this was only done when deallocating the
2571 memoryview), and gain support for the context management protocol.
2572
Antoine Pitrou079ce542010-09-08 12:37:10 +00002573- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2574 thread-local storage key.

Antoine Pitroudbec7802010-10-10 09:37:12 +00002588- Issue #9437: Fix building C extensions with non-default LDFLAGS.
2589
R. David Murray96fd54e2010-10-08 15:55:28 +00002590- Issue #4661: email can now parse bytes input and generate either converted
2591 7bit output or bytes output. Email version bumped to 5.1.0.
2592
Antoine Pitrou59fdd672010-10-08 10:37:08 +00002593- Issue #1589: Add ssl.match_hostname(), to help implement server identity
2594 verification for higher-level protocols.
2595
Antoine Pitrou7980eaa2010-10-06 21:21:18 +00002596- Issue #9759: GzipFile now raises ValueError when an operation is attempted
2597 after the file is closed. Patch by Jeffrey Finkelstein.
2598
Éric Araujo6108bf52010-10-04 23:52:37 +00002599- Issue #9042: Fix interaction of custom translation classes and caching in
2600 gettext.
2601
Éric Araujoef777bd2010-10-05 00:04:20 +00002602- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002603 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002604 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002605 replacement for old handle_accept() and avoids the user to call accept()
2606 directly.
2607
Lars Gustäbel331b8002010-10-04 15:18:47 +00002608- Issue #9065: tarfile no longer uses "root" as the default for the uname and

2612 an environment that does not have docutils. Patch by Arfrever.
Tarek Ziadé4bcceef2010-10-03 14:18:09 +00002613
R. David Murray5397e862010-10-02 15:58:26 +00002614- Issue #1050268: parseaddr now correctly quotes double quote and backslash
2615 characters that appear inside quoted strings in email addresses.
2616
Georg Brandl27a28582010-10-10 09:49:21 +00002617- Issue #10004: quoprimime no longer generates a traceback when confronted with

2624 conforms to the philosophy of bytes and unicode separation in Python 3. A
2625 test suite has also been added.

Antoine Pitrouc3ed2e72010-09-29 10:49:46 +00002627- Issue #9962: GzipFile now has the peek() method.
2628
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002629- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002630 retry the select() loop instead of bailing out. This is because select() can
2631 incorrectly report a socket as ready for reading (for example, if it received
2632 some data with an invalid checksum).
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002633
Hirokazu Yamamotocc868d42010-09-28 21:08:38 +00002634- Issue #3612: Added new types to ctypes.wintypes. (CHAR and pointers)

Georg Brandl27a28582010-10-10 09:49:21 +00002692- Issue #1552: socket.socketpair() now returns regular socket.socket objects
2693 supporting the whole socket API (rather than the "raw" _socket.socket
2694 objects).
Antoine Pitrou9e0b8642010-09-14 18:00:02 +00002695
Georg Brandl27a28582010-10-10 09:49:21 +00002696- Issue #9853: Fix the signature of SSLSocket.recvfrom() and SSLSocket.sendto()

Éric Araujod8c73c62011-03-21 03:15:22 +01002699- Issue #9840: Added a decorator to reprlib for wrapping __repr__ methods to make
Georg Brandl27a28582010-10-10 09:49:21 +00002700 them handle recursive calls within the same thread.

Victor Stinnerccb706c2010-09-13 19:41:36 +00002705
Antoine Pitrou6464d5f2010-09-12 14:51:20 +00002706- Issue #9837: The read() method of ZipExtFile objects (as returned by
2707 ZipFile.open()) could return more bytes than requested.
2708
Georg Brandl27a28582010-10-10 09:49:21 +00002709- Issue #9826: OrderedDict.__repr__ can now handle self-referential values:
2710 d['x'] = d.
Raymond Hettingerdc08a142010-09-12 05:15:22 +00002711
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002712- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002713 it possible for the user to create self-referencing ordered dictionaries which
2714 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002715 approach of using weakref proxies so that reference cycles never get created
2716 in the first place.
2717
Victor Stinnercb043522010-09-10 23:49:04 +00002718- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2719 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00002720 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00002721
Georg Brandl27a28582010-10-10 09:49:21 +00002722- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2723 environment variable to set the filesystem encoding at Python startup.
2724 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2725 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00002726
Georg Brandl27a28582010-10-10 09:49:21 +00002727- Issue #9410: Various optimizations to the pickle module, leading to speedups
2728 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
2729 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +00002730
Georg Brandl27a28582010-10-10 09:49:21 +00002731- The pprint module now supports printing OrderedDicts in their given order
2732 (formerly, it would sort the keys).
Raymond Hettingerbad3c882010-09-09 12:31:00 +00002733
Vinay Sajip121a1c42010-09-08 10:46:15 +00002734- Logging: Added QueueHandler class to facilitate logging usage with
2735 multiprocessing.
2736
Georg Brandl27a28582010-10-10 09:49:21 +00002737- Issue #9707: Rewritten reference implementation of threading.local which is
2738 friendlier towards reference cycles. This change is not normally visible
2739 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002740
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002741- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2742 still return the id of the parent process after it has exited. This process
2743 id may even have been reused by another unrelated process.
2744
Georg Brandl27a28582010-10-10 09:49:21 +00002745- Issue #9792: In case of connection failure, socket.create_connection() would
2746 swallow the exception and raise a new one, making it impossible to fetch the
2747 original errno, or to filter timeout errors. Now the original error is
2748 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002750- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2751 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2752 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +00002753
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002754- Updates to the random module:
2755
Georg Brandl27a28582010-10-10 09:49:21 +00002756 * Document which parts of the module are guaranteed to stay the same across
2757 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002758
Georg Brandl27a28582010-10-10 09:49:21 +00002759 * Update the seed() method to use all of the bits in a string instead of just
2760 the hash value. This makes better use of the seed value and assures the
2761 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002762
Georg Brandl27a28582010-10-10 09:49:21 +00002763 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2764 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2765 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002766
2767 * Improved documentation of arguments to randrange(). Issue #9379.

2773 cases now also have assertWarns and assertWarnsRegexp methods to check that a
2774 given warning type was triggered by the code under test.

2778 writable.

Antoine Pitrou0d739d72010-09-05 23:01:12 +00002782- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +00002783 unsupported operation is attempted (for example, writing to a file open only
2784 for reading).

Gregory P. Smith13b55292010-09-06 08:30:23 +00002786- hashlib has two new constant attributes: algorithms_guaranteed and
2787 algorithms_avaiable that respectively list the names of hash algorithms
2788 guaranteed to exist in all Python implementations and the names of hash
2789 algorithms available in the current process.
2790
Brian Quinlanaf38dc52010-09-21 12:28:43 +00002791- A new package ``concurrent.futures`` as defined by PEP 3148.

Georg Brandl649971e2010-09-05 17:06:50 +00002881- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
2882 the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our

Georg Brandl649971e2010-09-05 17:06:50 +00002894- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
2895 now removed, since their effect was inexistent in 3.x (the default encoding is

Georg Brandl649971e2010-09-05 17:06:50 +00002901- Issue #5553: The Py_LOCAL_INLINE macro now results in inlining on most
2902 platforms. Previously, it inlined only when using Microsoft Visual C.

2918 return characters from the full Unicode range, even on narrow unicode builds
2919 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2920 in Python is that unicodedata.numeric() now returns the correct value for
2921 large code points, and repr() may consider more characters as printable.
2922
Victor Stinner6c00c142010-08-17 23:37:11 +00002923- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

2925 unencodable filenames. Deprecate PyModule_GetFilename() in favor on the new
2926 function.

Georg Brandl649971e2010-09-05 17:06:50 +00002932- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when searching for
2933 the module file to be executed with the -m command line option.
Nick Coghland26c18a2010-08-17 13:06:11 +00002934

Ezio Melotti57221d02010-07-01 07:32:02 +00003301- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003302 start byte and the continuation byte(s) are now considered invalid, instead of
3303 the number of bytes specified by the start byte. E.g.:
3304 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3305 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3306 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3307 returned a single u'\ufffd'.

3336
Georg Brandl62069d32010-07-31 08:56:11 +00003337- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003338 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3339 location of the raised exception.
3340
Victor Stinner313a1202010-06-11 23:56:51 +00003341- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode

Georg Brandl62069d32010-07-31 08:56:11 +00003350- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3351 TypeError instead of giving a DeprecationWarning when a float is parsed using
3352 the 'L' code (for long long). (All other integer codes already raise
3353 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003354
Victor Stinner600d3be2010-06-10 12:00:55 +00003355- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3356 enable shortcuts for upper case encoding name. Add also a shortcut for
3357 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3358
Georg Brandl62069d32010-07-31 08:56:11 +00003359- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3360 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003361
3362- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003363 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003364 like bytearray.
3365
Georg Brandl62069d32010-07-31 08:56:11 +00003366- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003367 used anymore and it was never documented.
3368
Georg Brandl62069d32010-07-31 08:56:11 +00003369- In str.format(), raise a ValueError when indexes to arguments are too large.

Georg Brandl62069d32010-07-31 08:56:11 +00003374- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3375 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3376 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3377 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003378
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003379- Issue #8748: Fix two issues with comparisons between complex and integer
3380 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003381 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3382 (2) The comparison raised an OverflowError for large integers, leading to
3383 unpredictable exceptions when combining integers and complex objects in sets
3384 or dicts.

Georg Brandl62069d32010-07-31 08:56:11 +00003823 applications that use a lot of regular expressions and limits the impact of
3824 the performance hit anytime the cache is exceeded.

Raymond Hettingerc50846a2010-04-05 18:56:31 +00004222- Add functools.total_ordering() and functools.cmp_to_key().

Georg Brandl62069d32010-07-31 08:56:11 +00004233- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4234 InvalidOperation instead of returning False. (Comparisons involving a quiet
4235 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4236 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00004238- Issue #2531: Comparison operations between floats and Decimal instances now
4239 return a result based on the numeric values of the operands; previously they
4240 returned an arbitrary result based on the relative ordering of id(float) and
4241 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4242 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004243
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004244- Added a subtract() method to collections.Counter().
4245
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004246- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004247 argument `-` which tells it to read files to compile from stdin. Each line is

Florent Xicluna806d8cf2010-03-30 19:34:18 +00004251- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

4257 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4258 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004305- subprocess.Popen now has restore_signals and start_new_session features. The
4306 default of restore_signals=True is a new behavior compared to earlier Python
4307 versions. This means that signals such as SIGPIPE are not ignored by default
4308 in subprocesses launched by Python (Issue #1652).

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004801- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004802 compared to other unix systems. In particular, os.getgroups() does not reflect
4803 any changes made using os.setgroups() but basicly always returns the same
4804 information as the id command. os.getgroups() can now return more than 16
4805 groups on MacOSX.

Georg Brandl62069d32010-07-31 08:56:11 +00004830- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
4831 Prior to this change, timezone adjustment in utctimetuple() could produce
4832 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
4833 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00004835- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
4836 directive. When the ``%z`` directive is present in the format string, an
4837 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4838 ``datetime.timezone`` instance constructed from the parsed offset. If both
4839 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4840 name, but ``%Z`` data without ``%z`` is discarded.
Alexander Belopolskyca94f552010-06-17 18:30:34 +00004841
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00004842- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00004843 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4844 ``datetime.timezone``, return fixed name and UTC offset from their
4845 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4846 returns ``None``. A class attribute, ``utc`` contains an instance
4847 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00004863- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
4864 with an improved 'binary-split' algorithm that uses fewer multiplications and
4865 allows many of the multiplications to be performed using plain C integer
4866 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
4867 arguments.

4871
Mark Dickinson0381e3f2010-05-08 14:35:02 +00004872- Issue #8644: The accuracy of td.total_seconds() has been improved (by
4873 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00004874 the result is now always correctly rounded, and is equivalent to ``td /
4875 timedelta(seconds=1)``.

Mark Dickinsonc5935772010-04-03 15:54:36 +00004883- Issue #8300: When passing a non-integer argument to struct.pack with any
4884 integer format code, struct.pack first attempts to convert the non-integer
4885 using its __index__ method. If that method is non-existent or raises
4886 TypeError it goes on to try the __int__ method, as described below.

5161 threads could return successfully while some Thread objects were still

Georg Brandl62069d32010-07-31 08:56:11 +00005172 runtest_inner in regrtest, with warnings if the called test modifies them, and

5267 are always None now.
5268
Antoine Pitroud9dfaa92009-06-04 20:32:06 +00005269- Issue #6137: The pickle module now translates module names when loading
5270 or dumping pickles with a 2.x-compatible protocol, in order to make data
5271 sharing and migration easier. This behaviour can be disabled using the
5272 new `fix_imports` optional argument.

5325
Eric Smith41669ca2009-05-23 14:23:22 +00005326- Issue #6089: Fixed str.format with certain invalid field specifiers
5327 that would raise SystemError.
5328
Raymond Hettinger2bcde142009-05-29 04:52:27 +00005329- Issue #5982: staticmethod and classmethod now expose the wrapped
5330 function with __func__.
5331
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00005332- Added support for multiple context managers in the same with-statement.
5333 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00005335- Issue #5829: complex("1e500") no longer raises OverflowError. This
5336 makes it consistent with float("1e500") and interpretation of real
5337 and imaginary literals.
5338
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00005339- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

Mark Dickinsond1ec8b22009-05-11 15:45:15 +00005343- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
5344 (1) inf and nan strings with trailing whitespace were incorrectly
5345 rejected; (2) parsing of strings representing infinities and nans
5346 was locale aware; and (3) the interpretation of fromhex('-nan')
5347 didn't match that of float('-nan').

5353
R. David Murrayfb123912009-05-28 18:19:00 +00005354- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
5355
R. David Murray1f1b9d32009-05-27 20:56:59 +00005356- Issue #6121: pydoc now ignores leading and trailing spaces in the

5363 names: cls, self, tuple, itemgetter, and property.
5364
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00005365- In unittest, using a skipping decorator on a class is now equivalent to
5366 skipping every test on the class. The ClassTestSuite class has been removed.
5367
Martin v. Löwis70ccd162009-05-24 19:47:22 +00005368- Issue #6050: Don't fail extracting a directory from a zipfile if
5369 the directory already exists.
5370
Antoine Pitrou61f77b52009-05-24 15:46:13 +00005371- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
5372 than an int, which makes some operations possible under 64-bit Linux (e.g.
5373 DN_MULTISHOT with F_NOTIFY).
5374
Antoine Pitrou716c4442009-05-23 19:04:03 +00005375- Issue #5761: Add the name of the underlying file to the repr() of various
5376 IO objects.
5377

5379 by Musashi Tamura, tests by Marcin Bachry.
5380
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00005381- Issue #1983: Fix functions taking or returning a process identifier to use
5382 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
5383 a process identifier type wider than the standard C integer type.
5384
R. David Murray87e20742009-05-23 01:30:26 +00005385- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

5396
Antoine Pitroue4501852009-05-14 18:55:55 +00005397- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
5398 library. This means, for example, that opening an UTF-16 text file in
5399 append mode doesn't add a BOM at the end of the file if the file isn't
5400 empty.
5401
R. David Murray74b89242009-05-13 17:33:03 +00005402- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
5403 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
5404 corrects a pydoc regression.
5405
Georg Brandl5f90d792010-08-01 22:31:05 +00005406- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00005407 now it does. This also means getfp method now returns the real fp.

5450Core and Builtins
5451-----------------
5452
Mark Dickinson865e01a2009-05-07 16:37:01 +00005453- Issue #5914: Add new C API function PyOS_string_to_double, and
5454 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5455
Eric Smith741191f2009-05-06 13:08:15 +00005456- Issue #3382: float.__format__, complex.__format__, and %-formatting
5457 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5458 affects nan -> NAN and inf -> INF.
5459
Mark Hammond5a607a32009-05-06 08:04:54 +00005460- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5461 in all operations, including splitdrive, split, etc. splitunc() now issues
5462 a PendingDeprecation warning.
5463
Eric Smith63376222009-05-05 14:04:18 +00005464- Issue #5920: For float.__format__, change the behavior with the
5465 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5466 to be like 'g' but with at least one decimal point and with a
5467 default precision of 12. Previously, the behavior the same but with
5468 a default precision of 6. This more closely matches str(), and
5469 reduces surprises when adding alignment flags to the empty
5470 presentation type. This also affects the new complex.__format__ in
5471 the same way.
5472
Martin v. Löwis011e8422009-05-05 04:43:17 +00005473- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5474
R. David Murrayb18500d2009-05-04 22:59:07 +00005475- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5476 shadowed by classtype's, even if it was None. property now
5477 inserts the __doc__ into the subclass instance __dict__.
5478
Antoine Pitrou244651a2009-05-04 18:56:13 +00005479- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5480 sequences. Patch by Nick Barnes and Victor Stinner.
5481
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005482- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005483
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005484- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5485 received a new method, detach(). detach() disconnects the underlying stream
5486 from the buffer or text IO and returns it.
5487
Mark Dickinson33841c32009-05-01 15:37:04 +00005488- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5489 floats with absolute value over 1e50. Also remove length
5490 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5491 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005492
Eric Smith741191f2009-05-06 13:08:15 +00005493- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005494 format(complex(1, 2./3), '.5') now produces a sensible result.
5495
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005496- Issue #5864: Fix empty format code formatting for floats so that it
5497 never gives more than the requested number of significant digits.
5498
Eric Smith6dc46f52009-04-27 20:39:49 +00005499- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5500 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5501
Eric Smithcc32a112009-04-26 21:35:14 +00005502- Issue #5835: Deprecate PyOS_ascii_formatd.
5503
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005504- Issue #4971: Fix titlecase for characters that are their own
5505 titlecase, but not their own uppercase.
5506
Benjamin Peterson193152c2009-04-25 01:08:45 +00005507- Issue #5283: Setting __class__ in __del__ caused a segfault.
5508
Mark Dickinsonad476da2009-04-23 19:14:16 +00005509- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5510 z involves nans, infs or negative zeros.
5511
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005512- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005513
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005514- Issue #1869 (and many duplicates): make round(x, n) correctly
5515 rounded for a float x, by using the decimal <-> binary conversions
5516 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5517 consistently agrees with format(x, '.2f').
5518
Benjamin Petersonae937c02009-04-18 20:54:08 +00005519- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5520 some builtin types.
5521
Eric Smith0923d1d2009-04-16 20:16:10 +00005522- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5523
Eric Smith35e84722009-04-16 20:21:28 +00005524- Issue #5515: str.format() type 'n' combined with commas and leading
5525 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005526
5527- Implement PEP 378, Format Specifier for Thousands Separator, for
5528 floats.
5529
Mark Dickinson3370cce2009-04-17 22:40:53 +00005530- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005531 1e11, not 1e12. This avoids printing 13 significant digits in
5532 situations where only 12 of them are correct. Example problem
5533 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5534 long time.)
5535
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005536- Issue #1580: On most platforms, use a 'short' float repr: for a
5537 finite float x, repr(x) now outputs a string based on the shortest
5538 sequence of decimal digits that rounds to x. Previous behaviour was
5539 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005540 Another minor difference is that the new repr switches to
5541 exponential notation at 1e16 instead of the previous 1e17; this
5542 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005543
5544 There's a new sys attribute sys.float_repr_style, which takes
5545 the value 'short' to indicate that we're using short float repr,
5546 and 'legacy' if the short float repr isn't available for one
5547 reason or another.
5548
5549 The float repr change involves incorporating David Gay's 'perfect
5550 rounding' code into the Python core (it's in Python/dtoa.c). As a
5551 secondary consequence, all string-to-float and float-to-string
5552 conversions (including all float formatting operations) will be
5553 correctly rounded on these platforms.
5554
Georg Brandl5f90d792010-08-01 22:31:05 +00005555 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005556 this change does not apply.
5557
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005558- Issue #5759: float() didn't call __float__ on str subclasses.
5559

5562 the types string.maketrans() is supposed to work with, and mirrors the
5563 methods available on the str class.

Mark Dickinson87ec0852009-02-09 17:15:59 +00005857- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5858 it now forces its argument to double before testing for infinity.
5859
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005860- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5861 returns a non-number type.

Mark Dickinsonc008a172009-02-01 13:59:22 +00005865- Issue #1717: Removed builtin cmp() function, dropped tp_compare
5866 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00005867 the type definition cmpfunc. The tp_compare slot has been renamed
5868 to tp_reserved, and is reserved for future usage.

Georg Brandl1cdd83c2009-04-05 20:24:29 +00005870- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005871 were suppressing all exceptions. These include list() and bytearray().
5872
Mark Dickinson1124e712009-01-28 21:25:58 +00005873- Issue #4707: round(x, n) now returns an integer if x is an integer.
5874 Previously it returned a float.
5875
Antoine Pitroub52ec782009-01-25 16:34:23 +00005876- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5877 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5878 evaluation loop is compiled with a new dispatch mechanism which gives
5879 speedups of up to 20%, depending on the system, on various benchmarks.

Mark Dickinson8055afd2009-01-17 10:04:45 +00005891- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005892 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005893
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005894- Issue #4935: The overflow checking code in the expandtabs() method common
5895 to str, bytes and bytearray could be optimized away by the compiler, letting
5896 the interpreter segfault instead of raising an error.
5897
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005898- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5899 __next__ method.
5900
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005901- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5902 function no longer attempt to call the __long__ slot to convert an object
5903 to an integer. Only the __int__ and __trunc__ slots are examined.

5908
Antoine Pitrouab868312009-01-10 15:40:25 +00005909- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5910 common cases are optimized thanks to a dedicated fast path and a moderate
5911 amount of loop unrolling.
5912
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005913- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5914 collecting the oldest generation) so that allocating lots of objects without
5915 destroying them does not show quadratic performance. Based on a proposal by
5916 Martin von Löwis at
5917 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5918
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005919- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005920 having been closed (for instance, a read() call could return some
5921 previously buffered data). Patch by Dmitry Vasiliev.
5922
Antoine Pitrou05608432009-01-09 18:53:14 +00005923- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5924 flag to work properly. Furthermore, when specifying -u, the text stdout
5925 and stderr streams have line-by-line buffering enabled (the default being
5926 to buffer arbitrary chunks of data).
5927
Raymond Hettinger35631532009-01-09 03:58:09 +00005928- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5929 instead of ints (reducing its size from 4 to 8 times thereby reducing
5930 Python's overall memory).
5931
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005932- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5933 an existing .py counterpart, override the co_filename attributes of all
5934 code objects if the original filename is obsolete (which can happen if the
5935 file has been renamed, moved, or if it is accessed through different paths).
5936 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5937
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005938- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5939 one byte. Also fixes the meaning of len() so that it returns the number of
5940 items, rather than the size in bytes.
5941
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005942- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5943
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005944- Issue #4747: When the terminal does not use utf-8, executing a script with
5945 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5946
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005947- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed

5951 did not get collected.
5952
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005953- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5954 where the tp_hash and tp_dict slots are both NULL.
5955
Georg Brandlccc47b62008-12-28 11:44:14 +00005956- Issue #4759: None is now allowed as the first argument of
5957 bytearray.translate(). It was always allowed for bytes.translate().
5958
Skip Montanaro80072cb2008-12-23 03:51:14 +00005959- Added test case to ensure attempts to read from a file opened for writing
5960 fail.

Mark Dickinsonda2706b2008-12-11 18:03:03 +00005973- Issue #2173: When getting device encoding, check that return value of
5974 nl_langinfo is not the empty string. This was causing silent build
5975 failures on OS X.
5976
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005977- Issue #4597: Fixed several opcodes that weren't always propagating
5978 exceptions.
5979
5980- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005981 context manager returns a value that cannot be converted to a bool.
5982
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005983- Issue #4445: Replace "sizeof(PyBytesObject)" with
5984 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5985 bytes instances. On a typical machine this saves 3 bytes of memory
5986 (on average) per allocation of a bytes instance.
5987
Christian Heimesa872de52008-12-05 08:26:55 +00005988- Issue #4533: File read operation was dreadfully slow due to a slowly
5989 growing read buffer. Fixed by using the same growth rate algorithm as
5990 Python 2.x.
5991
Antoine Pitrou5504e892008-12-06 21:27:53 +00005992- Issue #4509: Various issues surrounding resize of bytearray objects to
5993 which there are buffer exports (e.g. memoryview instances).
5994
Georg Brandlf9734072008-12-07 15:30:06 +00005995- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5996 method on file objects with closefd=False. The file descriptor is still
5997 kept open but the file object behaves like a closed file. The ``FileIO``
5998 object also got a new readonly attribute ``closefd``.

Walter Dörwaldc1651a02009-05-03 22:55:55 +00006007- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6008 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6009 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6010 of using the replace error handler in PyUnicode_DecodeUTF8().
