Ned Deily657b2de2011-06-28 19:51:30 -0700640- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
641 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
642 interpreter process. This could cause failures in non-Distutils subprocesses
643 and was unreliable since tests or user programs could modify the interpreter
644 environment after Distutils set it. Instead, have Distutils set the the
645 deployment target only in the environment of each build subprocess. It is
646 still possible to globally override the default by setting
647 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
648 greater or equal to the default value, the value with which the interpreter
649 was built.

2491
Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002492- Issue #10068: Global objects which have reference cycles with their module's
2493 dict are now cleared again. This causes issue #7140 to appear again.
2494
Victor Stinner257d38f2010-10-09 10:12:11 +00002495- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00002496 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00002497
Georg Brandl27a28582010-10-10 09:49:21 +00002498- ast.literal_eval() can now handle negative numbers. It is also a little more
2499 liberal in what it accepts without compromising the safety of the evaluation.
2500 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00002501
Benjamin Peterson970d1882010-10-02 17:55:47 +00002502- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
2503 result metaclasses can now be ABCs (see #9533).
2504
Victor Stinneraef57e32010-10-02 11:50:49 +00002505- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
2506
Victor Stinner5593d8a2010-10-02 11:11:27 +00002507- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00002508 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
2509 32 bits wchar_t (eg. Linux in narrow build).

2515
Brett Cannon5305a992010-09-27 21:08:38 +00002516- Issue #7397: Mention that importlib.import_module() is probably what someone
2517 really wants to be using in __import__'s docstring.
2518
Georg Brandl27a28582010-10-10 09:49:21 +00002519- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
2520 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +00002521
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002522- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002523 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002524
Brian Curtine8e4b3b2010-09-23 20:04:14 +00002525- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
2526
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002527- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2528 threads are still running. Instead, reinitialize the GIL on a second call to
2529 Py_Initialize().
2530
Georg Brandl27a28582010-10-10 09:49:21 +00002531- All SyntaxErrors now have a column offset and therefore a caret when the error
2532 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00002533
Brett Cannonbc2eff32010-09-19 21:39:02 +00002534- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2535 module that was imported, but instead gets the module from sys.modules.
2536
Nick Coghlan37ee8502010-12-03 14:26:13 +00002537- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00002538 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00002539
Georg Brandl27a28582010-10-10 09:49:21 +00002540- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2541 with a non-empty format string. This is an effort to future-proof user
2542 code. If a derived class does not currently implement __format__ but later
2543 adds its own __format__, it would most likely break user code that had
2544 supplied a format string. This will be changed to a DeprecationWaring in
2545 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002546
Antoine Pitrou1df15362010-09-13 14:16:46 +00002547- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2548 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2549 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2550
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002551- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2552 functions from the libc caused the methods .upper() and lower() to become
2553 locale aware and created subtly wrong results.
2554
Georg Brandl27a28582010-10-10 09:49:21 +00002555- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2556 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002557
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002558- Issue #4617: Previously it was illegal to delete a name from the local
2559 namespace if it occurs as a free variable in a nested block. This limitation
2560 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2561
Georg Brandl27a28582010-10-10 09:49:21 +00002562- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2563 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2564 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2565 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002566
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002567- Issue #9757: memoryview objects get a release() method to release the
2568 underlying buffer (previously this was only done when deallocating the
2569 memoryview), and gain support for the context management protocol.
2570
Antoine Pitrou079ce542010-09-08 12:37:10 +00002571- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2572 thread-local storage key.

R. David Murray96fd54e2010-10-08 15:55:28 +00002588- Issue #4661: email can now parse bytes input and generate either converted
2589 7bit output or bytes output. Email version bumped to 5.1.0.
2590
Antoine Pitrou59fdd672010-10-08 10:37:08 +00002591- Issue #1589: Add ssl.match_hostname(), to help implement server identity

2593
Antoine Pitrou7980eaa2010-10-06 21:21:18 +00002594- Issue #9759: GzipFile now raises ValueError when an operation is attempted

2596
Éric Araujo6108bf52010-10-04 23:52:37 +00002597- Issue #9042: Fix interaction of custom translation classes and caching in
2598 gettext.
2599
Éric Araujoef777bd2010-10-05 00:04:20 +00002600- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002601 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002602 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002603 replacement for old handle_accept() and avoids the user to call accept()
2604 directly.

Lars Gustäbel331b8002010-10-04 15:18:47 +00002606- Issue #9065: tarfile no longer uses "root" as the default for the uname and

R. David Murray5397e862010-10-02 15:58:26 +00002612- Issue #1050268: parseaddr now correctly quotes double quote and backslash

Georg Brandl27a28582010-10-10 09:49:21 +00002615- Issue #10004: quoprimime no longer generates a traceback when confronted with

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002627- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002628 retry the select() loop instead of bailing out. This is because select() can
2629 incorrectly report a socket as ready for reading (for example, if it received
2630 some data with an invalid checksum).

Georg Brandl27a28582010-10-10 09:49:21 +00002690- Issue #1552: socket.socketpair() now returns regular socket.socket objects
2691 supporting the whole socket API (rather than the "raw" _socket.socket
2692 objects).
Antoine Pitrou9e0b8642010-09-14 18:00:02 +00002693
Georg Brandl27a28582010-10-10 09:49:21 +00002694- Issue #9853: Fix the signature of SSLSocket.recvfrom() and SSLSocket.sendto()
2695 to match the corresponding socket methods.

Éric Araujod8c73c62011-03-21 03:15:22 +01002697- Issue #9840: Added a decorator to reprlib for wrapping __repr__ methods to make
Georg Brandl27a28582010-10-10 09:49:21 +00002698 them handle recursive calls within the same thread.

Victor Stinnerccb706c2010-09-13 19:41:36 +00002703
Antoine Pitrou6464d5f2010-09-12 14:51:20 +00002704- Issue #9837: The read() method of ZipExtFile objects (as returned by
2705 ZipFile.open()) could return more bytes than requested.
2706
Georg Brandl27a28582010-10-10 09:49:21 +00002707- Issue #9826: OrderedDict.__repr__ can now handle self-referential values:
2708 d['x'] = d.
Raymond Hettingerdc08a142010-09-12 05:15:22 +00002709
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002710- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002711 it possible for the user to create self-referencing ordered dictionaries which
2712 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002713 approach of using weakref proxies so that reference cycles never get created
2714 in the first place.
2715
Victor Stinnercb043522010-09-10 23:49:04 +00002716- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2717 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00002718 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00002719
Georg Brandl27a28582010-10-10 09:49:21 +00002720- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2721 environment variable to set the filesystem encoding at Python startup.
2722 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2723 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00002724
Georg Brandl27a28582010-10-10 09:49:21 +00002725- Issue #9410: Various optimizations to the pickle module, leading to speedups
2726 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
2727 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +00002728
Georg Brandl27a28582010-10-10 09:49:21 +00002729- The pprint module now supports printing OrderedDicts in their given order
2730 (formerly, it would sort the keys).
Raymond Hettingerbad3c882010-09-09 12:31:00 +00002731
Vinay Sajip121a1c42010-09-08 10:46:15 +00002732- Logging: Added QueueHandler class to facilitate logging usage with
2733 multiprocessing.
2734
Georg Brandl27a28582010-10-10 09:49:21 +00002735- Issue #9707: Rewritten reference implementation of threading.local which is
2736 friendlier towards reference cycles. This change is not normally visible
2737 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002738
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002739- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2740 still return the id of the parent process after it has exited. This process
2741 id may even have been reused by another unrelated process.
2742
Georg Brandl27a28582010-10-10 09:49:21 +00002743- Issue #9792: In case of connection failure, socket.create_connection() would
2744 swallow the exception and raise a new one, making it impossible to fetch the
2745 original errno, or to filter timeout errors. Now the original error is
2746 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002748- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2749 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2750 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +00002751
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002752- Updates to the random module:
2753
Georg Brandl27a28582010-10-10 09:49:21 +00002754 * Document which parts of the module are guaranteed to stay the same across
2755 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002756
Georg Brandl27a28582010-10-10 09:49:21 +00002757 * Update the seed() method to use all of the bits in a string instead of just
2758 the hash value. This makes better use of the seed value and assures the
2759 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002760
Georg Brandl27a28582010-10-10 09:49:21 +00002761 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2762 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2763 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002764
2765 * Improved documentation of arguments to randrange(). Issue #9379.

2771 cases now also have assertWarns and assertWarnsRegexp methods to check that a
2772 given warning type was triggered by the code under test.

Antoine Pitrou0d739d72010-09-05 23:01:12 +00002780- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +00002781 unsupported operation is attempted (for example, writing to a file open only
2782 for reading).

Gregory P. Smith13b55292010-09-06 08:30:23 +00002784- hashlib has two new constant attributes: algorithms_guaranteed and
2785 algorithms_avaiable that respectively list the names of hash algorithms
2786 guaranteed to exist in all Python implementations and the names of hash
2787 algorithms available in the current process.
2788
Brian Quinlanaf38dc52010-09-21 12:28:43 +00002789- A new package ``concurrent.futures`` as defined by PEP 3148.

Georg Brandl649971e2010-09-05 17:06:50 +00002879- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
2880 the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our
2881 bytecode is a bit simplified. Patch by Demur Rumed.

Georg Brandl649971e2010-09-05 17:06:50 +00002892- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
2893 now removed, since their effect was inexistent in 3.x (the default encoding is
2894 hardcoded to utf-8 and cannot be changed).
Antoine Pitroufce7fd62010-09-01 18:54:56 +00002895
Antoine Pitroub0fa8312010-09-01 15:10:12 +00002896- Issue #7415: PyUnicode_FromEncodedObject() now uses the new buffer API

2898
Georg Brandl649971e2010-09-05 17:06:50 +00002899- Issue #5553: The Py_LOCAL_INLINE macro now results in inlining on most
2900 platforms. Previously, it inlined only when using Microsoft Visual C.

2916 return characters from the full Unicode range, even on narrow unicode builds
2917 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2918 in Python is that unicodedata.numeric() now returns the correct value for
2919 large code points, and repr() may consider more characters as printable.
2920
Victor Stinner6c00c142010-08-17 23:37:11 +00002921- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename
2922 as a unicode object, instead of a byte string. Function needed to support
2923 unencodable filenames. Deprecate PyModule_GetFilename() in favor on the new
2924 function.
2925
Victor Stinner6961bd62010-08-17 22:26:51 +00002926- Issue #8063: Call _PyGILState_Init() earlier in Py_InitializeEx().

Georg Brandl649971e2010-09-05 17:06:50 +00002930- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when searching for
2931 the module file to be executed with the -m command line option.
Nick Coghland26c18a2010-08-17 13:06:11 +00002932

Ezio Melotti57221d02010-07-01 07:32:02 +00003299- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003300 start byte and the continuation byte(s) are now considered invalid, instead of
3301 the number of bytes specified by the start byte. E.g.:
3302 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3303 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3304 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3305 returned a single u'\ufffd'.

3334
Georg Brandl62069d32010-07-31 08:56:11 +00003335- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003336 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module

Georg Brandl62069d32010-07-31 08:56:11 +00003348- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3349 TypeError instead of giving a DeprecationWarning when a float is parsed using
3350 the 'L' code (for long long). (All other integer codes already raise
3351 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003352
Victor Stinner600d3be2010-06-10 12:00:55 +00003353- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3354 enable shortcuts for upper case encoding name. Add also a shortcut for
3355 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3356
Georg Brandl62069d32010-07-31 08:56:11 +00003357- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3358 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003359
3360- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003361 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003362 like bytearray.
3363
Georg Brandl62069d32010-07-31 08:56:11 +00003364- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003365 used anymore and it was never documented.

Georg Brandl62069d32010-07-31 08:56:11 +00003372- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3373 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3374 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3375 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003376
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003377- Issue #8748: Fix two issues with comparisons between complex and integer
3378 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003379 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3380 (2) The comparison raised an OverflowError for large integers, leading to
3381 unpredictable exceptions when combining integers and complex objects in sets
3382 or dicts.

3820 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003821 applications that use a lot of regular expressions and limits the impact of
3822 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00004231- Issue #7279: Comparisons involving a Decimal signaling NaN now signal

Georg Brandl62069d32010-07-31 08:56:11 +00004236- Issue #2531: Comparison operations between floats and Decimal instances now
4237 return a result based on the numeric values of the operands; previously they
4238 returned an arbitrary result based on the relative ordering of id(float) and
4239 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4240 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004241
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004242- Added a subtract() method to collections.Counter().
4243
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004244- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004245 argument `-` which tells it to read files to compile from stdin. Each line is

4255 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4256 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004303- subprocess.Popen now has restore_signals and start_new_session features. The
4304 default of restore_signals=True is a new behavior compared to earlier Python
4305 versions. This means that signals such as SIGPIPE are not ignored by default
4306 in subprocesses launched by Python (Issue #1652).

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004799- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004800 compared to other unix systems. In particular, os.getgroups() does not reflect
4801 any changes made using os.setgroups() but basicly always returns the same
4802 information as the id command. os.getgroups() can now return more than 16
4803 groups on MacOSX.

Georg Brandl62069d32010-07-31 08:56:11 +00004828- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
4829 Prior to this change, timezone adjustment in utctimetuple() could produce
4830 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
4831 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00004833- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
4834 directive. When the ``%z`` directive is present in the format string, an
4835 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4836 ``datetime.timezone`` instance constructed from the parsed offset. If both
4837 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4838 name, but ``%Z`` data without ``%z`` is discarded.
Alexander Belopolskyca94f552010-06-17 18:30:34 +00004839
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00004840- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00004841 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4842 ``datetime.timezone``, return fixed name and UTC offset from their
4843 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4844 returns ``None``. A class attribute, ``utc`` contains an instance
4845 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00004861- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
4862 with an improved 'binary-split' algorithm that uses fewer multiplications and
4863 allows many of the multiplications to be performed using plain C integer
4864 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
4865 arguments.

4869
Mark Dickinson0381e3f2010-05-08 14:35:02 +00004870- Issue #8644: The accuracy of td.total_seconds() has been improved (by
4871 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00004872 the result is now always correctly rounded, and is equivalent to ``td /
4873 timedelta(seconds=1)``.

Mark Dickinsonc5935772010-04-03 15:54:36 +00004881- Issue #8300: When passing a non-integer argument to struct.pack with any
4882 integer format code, struct.pack first attempts to convert the non-integer
4883 using its __index__ method. If that method is non-existent or raises
4884 TypeError it goes on to try the __int__ method, as described below.

5159 threads could return successfully while some Thread objects were still

Georg Brandl62069d32010-07-31 08:56:11 +00005170 runtest_inner in regrtest, with warnings if the called test modifies them, and

5265 are always None now.
5266
Antoine Pitroud9dfaa92009-06-04 20:32:06 +00005267- Issue #6137: The pickle module now translates module names when loading
5268 or dumping pickles with a 2.x-compatible protocol, in order to make data
5269 sharing and migration easier. This behaviour can be disabled using the
5270 new `fix_imports` optional argument.

5275 base64.{encode,decode}bytes which reflects what type they accept and return.
5276 The old names are still there as deprecated aliases.
5277

5323
Eric Smith41669ca2009-05-23 14:23:22 +00005324- Issue #6089: Fixed str.format with certain invalid field specifiers
5325 that would raise SystemError.
5326
Raymond Hettinger2bcde142009-05-29 04:52:27 +00005327- Issue #5982: staticmethod and classmethod now expose the wrapped
5328 function with __func__.
5329
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00005330- Added support for multiple context managers in the same with-statement.
5331 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00005333- Issue #5829: complex("1e500") no longer raises OverflowError. This
5334 makes it consistent with float("1e500") and interpretation of real
5335 and imaginary literals.
5336
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00005337- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

Mark Dickinsond1ec8b22009-05-11 15:45:15 +00005341- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
5342 (1) inf and nan strings with trailing whitespace were incorrectly
5343 rejected; (2) parsing of strings representing infinities and nans
5344 was locale aware; and (3) the interpretation of fromhex('-nan')
5345 didn't match that of float('-nan').

Martin v. Löwisb6a748b2009-05-29 15:23:17 +00005350- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
5351
R. David Murrayfb123912009-05-28 18:19:00 +00005352- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
5353
R. David Murray1f1b9d32009-05-27 20:56:59 +00005354- Issue #6121: pydoc now ignores leading and trailing spaces in the

5361 names: cls, self, tuple, itemgetter, and property.
5362
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00005363- In unittest, using a skipping decorator on a class is now equivalent to
5364 skipping every test on the class. The ClassTestSuite class has been removed.
5365
Martin v. Löwis70ccd162009-05-24 19:47:22 +00005366- Issue #6050: Don't fail extracting a directory from a zipfile if
5367 the directory already exists.
5368
Antoine Pitrou61f77b52009-05-24 15:46:13 +00005369- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
5370 than an int, which makes some operations possible under 64-bit Linux (e.g.
5371 DN_MULTISHOT with F_NOTIFY).
5372
Antoine Pitrou716c4442009-05-23 19:04:03 +00005373- Issue #5761: Add the name of the underlying file to the repr() of various
5374 IO objects.
5375
R. David Murraycaa27b72009-05-23 18:49:56 +00005376- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
5377 by Musashi Tamura, tests by Marcin Bachry.
5378
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00005379- Issue #1983: Fix functions taking or returning a process identifier to use
5380 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
5381 a process identifier type wider than the standard C integer type.
5382
R. David Murray87e20742009-05-23 01:30:26 +00005383- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

5394
Antoine Pitroue4501852009-05-14 18:55:55 +00005395- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
5396 library. This means, for example, that opening an UTF-16 text file in
5397 append mode doesn't add a BOM at the end of the file if the file isn't
5398 empty.
5399
R. David Murray74b89242009-05-13 17:33:03 +00005400- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
5401 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
5402 corrects a pydoc regression.
5403
Georg Brandl5f90d792010-08-01 22:31:05 +00005404- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00005405 now it does. This also means getfp method now returns the real fp.

Georg Brandl5f90d792010-08-01 22:31:05 +00005437- Issue #5442: Tests for importlib were not properly skipping case-sensitivity
Brett Cannon1262e7c2009-05-11 01:47:11 +00005438 tests on darwin even when the OS was installed on a case-sensitive

5448Core and Builtins
5449-----------------
5450
Mark Dickinson865e01a2009-05-07 16:37:01 +00005451- Issue #5914: Add new C API function PyOS_string_to_double, and
5452 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5453
Eric Smith741191f2009-05-06 13:08:15 +00005454- Issue #3382: float.__format__, complex.__format__, and %-formatting
5455 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5456 affects nan -> NAN and inf -> INF.
5457
Mark Hammond5a607a32009-05-06 08:04:54 +00005458- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5459 in all operations, including splitdrive, split, etc. splitunc() now issues
5460 a PendingDeprecation warning.
5461
Eric Smith63376222009-05-05 14:04:18 +00005462- Issue #5920: For float.__format__, change the behavior with the
5463 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5464 to be like 'g' but with at least one decimal point and with a
5465 default precision of 12. Previously, the behavior the same but with
5466 a default precision of 6. This more closely matches str(), and
5467 reduces surprises when adding alignment flags to the empty
5468 presentation type. This also affects the new complex.__format__ in
5469 the same way.
5470
Martin v. Löwis011e8422009-05-05 04:43:17 +00005471- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5472
R. David Murrayb18500d2009-05-04 22:59:07 +00005473- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5474 shadowed by classtype's, even if it was None. property now
5475 inserts the __doc__ into the subclass instance __dict__.
5476
Antoine Pitrou244651a2009-05-04 18:56:13 +00005477- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5478 sequences. Patch by Nick Barnes and Victor Stinner.
5479
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005480- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005481
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005482- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5483 received a new method, detach(). detach() disconnects the underlying stream
5484 from the buffer or text IO and returns it.
5485
Mark Dickinson33841c32009-05-01 15:37:04 +00005486- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5487 floats with absolute value over 1e50. Also remove length
5488 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5489 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005490
Eric Smith741191f2009-05-06 13:08:15 +00005491- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005492 format(complex(1, 2./3), '.5') now produces a sensible result.
5493
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005494- Issue #5864: Fix empty format code formatting for floats so that it
5495 never gives more than the requested number of significant digits.
5496
Eric Smith6dc46f52009-04-27 20:39:49 +00005497- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5498 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5499
Eric Smithcc32a112009-04-26 21:35:14 +00005500- Issue #5835: Deprecate PyOS_ascii_formatd.
5501
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005502- Issue #4971: Fix titlecase for characters that are their own
5503 titlecase, but not their own uppercase.
5504
Benjamin Peterson193152c2009-04-25 01:08:45 +00005505- Issue #5283: Setting __class__ in __del__ caused a segfault.
5506
Mark Dickinsonad476da2009-04-23 19:14:16 +00005507- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5508 z involves nans, infs or negative zeros.
5509
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005510- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005511
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005512- Issue #1869 (and many duplicates): make round(x, n) correctly
5513 rounded for a float x, by using the decimal <-> binary conversions
5514 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5515 consistently agrees with format(x, '.2f').
5516
Benjamin Petersonae937c02009-04-18 20:54:08 +00005517- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5518 some builtin types.
5519
Eric Smith0923d1d2009-04-16 20:16:10 +00005520- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5521
Eric Smith35e84722009-04-16 20:21:28 +00005522- Issue #5515: str.format() type 'n' combined with commas and leading
5523 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005524
5525- Implement PEP 378, Format Specifier for Thousands Separator, for
5526 floats.
5527
Mark Dickinson3370cce2009-04-17 22:40:53 +00005528- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005529 1e11, not 1e12. This avoids printing 13 significant digits in
5530 situations where only 12 of them are correct. Example problem
5531 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5532 long time.)
5533
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005534- Issue #1580: On most platforms, use a 'short' float repr: for a
5535 finite float x, repr(x) now outputs a string based on the shortest
5536 sequence of decimal digits that rounds to x. Previous behaviour was
5537 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005538 Another minor difference is that the new repr switches to
5539 exponential notation at 1e16 instead of the previous 1e17; this
5540 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005541
5542 There's a new sys attribute sys.float_repr_style, which takes
5543 the value 'short' to indicate that we're using short float repr,
5544 and 'legacy' if the short float repr isn't available for one
5545 reason or another.
5546
5547 The float repr change involves incorporating David Gay's 'perfect
5548 rounding' code into the Python core (it's in Python/dtoa.c). As a
5549 secondary consequence, all string-to-float and float-to-string
5550 conversions (including all float formatting operations) will be
5551 correctly rounded on these platforms.
5552
Georg Brandl5f90d792010-08-01 22:31:05 +00005553 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005554 this change does not apply.
5555
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005556- Issue #5759: float() didn't call __float__ on str subclasses.
5557

5560 the types string.maketrans() is supposed to work with, and mirrors the
5561 methods available on the str class.

Mark Dickinson87ec0852009-02-09 17:15:59 +00005855- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5856 it now forces its argument to double before testing for infinity.
5857
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005858- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonc008a172009-02-01 13:59:22 +00005863- Issue #1717: Removed builtin cmp() function, dropped tp_compare
5864 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00005865 the type definition cmpfunc. The tp_compare slot has been renamed

Georg Brandl1cdd83c2009-04-05 20:24:29 +00005868- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005869 were suppressing all exceptions. These include list() and bytearray().
5870
Mark Dickinson1124e712009-01-28 21:25:58 +00005871- Issue #4707: round(x, n) now returns an integer if x is an integer.
5872 Previously it returned a float.
5873
Antoine Pitroub52ec782009-01-25 16:34:23 +00005874- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5875 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5876 evaluation loop is compiled with a new dispatch mechanism which gives
5877 speedups of up to 20%, depending on the system, on various benchmarks.

5888
Mark Dickinson8055afd2009-01-17 10:04:45 +00005889- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005890 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005891
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005892- Issue #4935: The overflow checking code in the expandtabs() method common
5893 to str, bytes and bytearray could be optimized away by the compiler, letting
5894 the interpreter segfault instead of raising an error.
5895
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005896- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5897 __next__ method.
5898
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005899- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5900 function no longer attempt to call the __long__ slot to convert an object
5901 to an integer. Only the __int__ and __trunc__ slots are examined.

5906
Antoine Pitrouab868312009-01-10 15:40:25 +00005907- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5908 common cases are optimized thanks to a dedicated fast path and a moderate
5909 amount of loop unrolling.
5910
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005911- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5912 collecting the oldest generation) so that allocating lots of objects without
5913 destroying them does not show quadratic performance. Based on a proposal by
5914 Martin von Löwis at
5915 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5916
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005917- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005918 having been closed (for instance, a read() call could return some
5919 previously buffered data). Patch by Dmitry Vasiliev.
5920
Antoine Pitrou05608432009-01-09 18:53:14 +00005921- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5922 flag to work properly. Furthermore, when specifying -u, the text stdout
5923 and stderr streams have line-by-line buffering enabled (the default being
5924 to buffer arbitrary chunks of data).
5925
Raymond Hettinger35631532009-01-09 03:58:09 +00005926- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5927 instead of ints (reducing its size from 4 to 8 times thereby reducing
5928 Python's overall memory).
5929
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005930- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5931 an existing .py counterpart, override the co_filename attributes of all
5932 code objects if the original filename is obsolete (which can happen if the
5933 file has been renamed, moved, or if it is accessed through different paths).
5934 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5935
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005936- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5937 one byte. Also fixes the meaning of len() so that it returns the number of
5938 items, rather than the size in bytes.
5939
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005940- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5941
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005942- Issue #4747: When the terminal does not use utf-8, executing a script with
5943 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5944
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005945- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed

5949 did not get collected.
5950
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005951- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5952 where the tp_hash and tp_dict slots are both NULL.
5953
Georg Brandlccc47b62008-12-28 11:44:14 +00005954- Issue #4759: None is now allowed as the first argument of
5955 bytearray.translate(). It was always allowed for bytes.translate().
5956
Skip Montanaro80072cb2008-12-23 03:51:14 +00005957- Added test case to ensure attempts to read from a file opened for writing
5958 fail.

5964
Antoine Pitrou621601a2008-12-17 23:18:19 +00005965- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

5970
Mark Dickinsonda2706b2008-12-11 18:03:03 +00005971- Issue #2173: When getting device encoding, check that return value of
5972 nl_langinfo is not the empty string. This was causing silent build
5973 failures on OS X.
5974
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005975- Issue #4597: Fixed several opcodes that weren't always propagating
5976 exceptions.
5977
5978- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005979 context manager returns a value that cannot be converted to a bool.
5980
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005981- Issue #4445: Replace "sizeof(PyBytesObject)" with
5982 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5983 bytes instances. On a typical machine this saves 3 bytes of memory
5984 (on average) per allocation of a bytes instance.
5985
Christian Heimesa872de52008-12-05 08:26:55 +00005986- Issue #4533: File read operation was dreadfully slow due to a slowly
5987 growing read buffer. Fixed by using the same growth rate algorithm as
5988 Python 2.x.
5989
Antoine Pitrou5504e892008-12-06 21:27:53 +00005990- Issue #4509: Various issues surrounding resize of bytearray objects to
5991 which there are buffer exports (e.g. memoryview instances).
5992
Georg Brandlf9734072008-12-07 15:30:06 +00005993- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5994 method on file objects with closefd=False. The file descriptor is still
5995 kept open but the file object behaves like a closed file. The ``FileIO``
5996 object also got a new readonly attribute ``closefd``.

Walter Dörwaldc1651a02009-05-03 22:55:55 +00006005- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6006 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6007 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6008 of using the replace error handler in PyUnicode_DecodeUTF8().
