Georg Brandl62069d32010-07-31 08:56:11 +0000297- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
298 TypeError instead of giving a DeprecationWarning when a float is parsed using
299 the 'L' code (for long long). (All other integer codes already raise
300 TypeError in this case.)

Georg Brandl62069d32010-07-31 08:56:11 +0000310 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects

Mark Dickinsoncc6a9822010-05-21 14:55:26 +0000326- Issue #8748: Fix two issues with comparisons between complex and integer
327 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +0000328 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
329 (2) The comparison raised an OverflowError for large integers, leading to
330 unpredictable exceptions when combining integers and complex objects in sets
331 or dicts.

661 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
662 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +0000663 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +0000766- The default size of the re module's compiled regular expression cache has been
767 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +0000768 simply clearing the entire cache on overflow to forgetting the least recently
769 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +0000770 applications that use a lot of regular expressions and limits the impact of
771 the performance hit anytime the cache is exceeded.

784 module is renamed to `_datetime` and if available, overrides all classes
785 defined in datetime with fast C impementation. Python implementation is based
786 on the original python prototype for the datetime module by Tim Peters with
787 minor modifications by the PyPy project. The test suite now tests `datetime`
788 module with and without `_datetime` acceleration using the same test cases.

Benjamin Peterson225168e2010-05-06 22:29:53 +00001002- Issue #8603: Support bytes environmental variables on Unix: Add os.environb
1003 mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
1004 file system encoding with the surrogateescape error handler (instead of
1005 utf8/strict) and accepts bytes. posix.environ keys and values are now bytes.

1016
Victor Stinnerd17f2192010-08-15 09:56:07 +00001017- Issue #8390: tarfile uses surrogateescape as the default error handler
Georg Brandl62069d32010-07-31 08:56:11 +00001018 (instead of replace in read mode or strict in write mode).

Georg Brandl62069d32010-07-31 08:56:11 +00001025- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
1026 operation raises multiple signals and more than one of those signals is
1027 trapped, the specification determines the order in which the signals should be
1028 handled. In many cases this order wasn't being followed, leading to the wrong
1029 Python exception being raised.

Georg Brandl62069d32010-07-31 08:56:11 +00001068- Issue #8524: When creating an SSL socket, the timeout value of the original
1069 socket wasn't retained (instead, a socket with a positive timeout would be
1070 turned into a non-blocking SSL socket).

1074
Georg Brandl62069d32010-07-31 08:56:11 +00001075- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Georg Brandl62069d32010-07-31 08:56:11 +00001091- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
1092 non-infinite timeout. Also make that method friendlier with applications
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +00001093 wanting to continue using the socket in clear-text mode, by disabling

Georg Brandl62069d32010-07-31 08:56:11 +00001185- Issue #2531: Comparison operations between floats and Decimal instances now
1186 return a result based on the numeric values of the operands; previously they
1187 returned an arbitrary result based on the relative ordering of id(float) and
1188 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
1189 comparisons.

1204 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1205 <=> complex, and complex <=> complex comparisons.

Tarek Ziadéacafc2d2009-11-29 22:24:57 +00001463- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
1464 ownership when the group is not forced, because the group may be different

Georg Brandl62069d32010-07-31 08:56:11 +00001510- Issue #6816: runpy now provides a run_path function that allows Python code to
1511 execute file paths that refer to source or compiled Python files as well as
1512 zipfiles, directories and other valid sys.path entries that contain a
1513 __main__.py file. This allows applications that run other Python scripts to
Nick Coghlan260bd3e2009-11-16 06:49:25 +00001514 support the same flexibility as the CPython command line itself.
1515

1517 connection with another process, rather than looping endlessly. The default

1523
Michael Foord34c94622010-02-10 15:51:42 +00001524- Issue #7893: ``unittest.TextTestResult`` is made public and a ``resultclass``
1525 argument added to the TextTestRunner constructor allowing a different result
1526 class to be used without having to subclass.
Victor Stinnere125f132010-05-15 21:04:43 +00001527
Georg Brandl5f90d792010-08-01 22:31:05 +00001528- Issue #7588: ``unittest.TextTestResult.getDescription`` now includes the test
Michael Foord34c94622010-02-10 15:51:42 +00001529 name in failure reports even if the test has a docstring.
1530
Antoine Pitrou434736a2009-11-10 18:46:01 +00001531- Issue #3001: Add a C implementation of recursive locks which is used by
Georg Brandl62069d32010-07-31 08:56:11 +00001532 default when instantiating a `threading.RLock` object. This makes recursive
1533 locks as fast as regular non-recursive locks (previously, they were slower by
1534 10x to 15x).
Antoine Pitrou434736a2009-11-10 18:46:01 +00001535

1537 those started through `threading.Thread` (for example, using
Antoine Pitroub0872682009-11-09 16:08:16 +00001538 `_thread.start_new_thread()`).
1539

1550 modification is done through it. This fixes inconsistencies and test failures
1551 on systems with slightly bogus mtime behaviour.

Georg Brandl62069d32010-07-31 08:56:11 +00001553- Issue #7246 & Issue #7208: getpass now properly flushes input before reading
1554 from stdin so that existing input does not confuse it and lead to incorrect
1555 entry or an IOError. It also properly flushes it afterwards to avoid the
1556 terminal echoing the input afterwards on OSes such as Solaris.

1560 large arguments (those with coefficient longer than the current precision) in
1561 shift and rotate.

1741
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00001742- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00001743 compared to other unix systems. In particular, os.getgroups() does not reflect
1744 any changes made using os.setgroups() but basicly always returns the same
1745 information as the id command. os.getgroups() can now return more than 16
1746 groups on MacOSX.

Georg Brandl62069d32010-07-31 08:56:11 +00001771- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
1772 Prior to this change, timezone adjustment in utctimetuple() could produce
1773 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
1774 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00001776- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
1777 directive. When the ``%z`` directive is present in the format string, an
1778 aware ``datetime`` object is returned with ``tzinfo`` bound to a
1779 ``datetime.timezone`` instance constructed from the parsed offset. If both
1780 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
1781 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00001783- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00001784 implementing ``datetime.tzinfo`` interface. Instances of the new class,
1785 ``datetime.timezone``, return fixed name and UTC offset from their
1786 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
1787 returns ``None``. A class attribute, ``utc`` contains an instance
1788 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00001804- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
1805 with an improved 'binary-split' algorithm that uses fewer multiplications and
1806 allows many of the multiplications to be performed using plain C integer
1807 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small

Mark Dickinson0381e3f2010-05-08 14:35:02 +00001813- Issue #8644: The accuracy of td.total_seconds() has been improved (by
1814 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00001815 the result is now always correctly rounded, and is equivalent to ``td /
1816 timedelta(seconds=1)``.

1825 integer format code, struct.pack first attempts to convert the non-integer
1826 using its __index__ method. If that method is non-existent or raises
1827 TypeError it goes on to try the __int__ method, as described below.

Mark Dickinson865e01a2009-05-07 16:37:01 +00002391- Issue #5914: Add new C API function PyOS_string_to_double, and
2392 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
2393
Eric Smith741191f2009-05-06 13:08:15 +00002394- Issue #3382: float.__format__, complex.__format__, and %-formatting
2395 no longer map 'F' to 'f'. Because of issue #5859 (below), this only

2397
Mark Hammond5a607a32009-05-06 08:04:54 +00002398- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
2399 in all operations, including splitdrive, split, etc. splitunc() now issues
2400 a PendingDeprecation warning.
2401
Eric Smith63376222009-05-05 14:04:18 +00002402- Issue #5920: For float.__format__, change the behavior with the
2403 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
2404 to be like 'g' but with at least one decimal point and with a
2405 default precision of 12. Previously, the behavior the same but with
2406 a default precision of 6. This more closely matches str(), and
2407 reduces surprises when adding alignment flags to the empty
2408 presentation type. This also affects the new complex.__format__ in
2409 the same way.
2410
Martin v. Löwis011e8422009-05-05 04:43:17 +00002411- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

R. David Murrayb18500d2009-05-04 22:59:07 +00002413- Issue #5890: in subclasses of 'property' the __doc__ attribute was
2414 shadowed by classtype's, even if it was None. property now
2415 inserts the __doc__ into the subclass instance __dict__.
2416
Antoine Pitrou244651a2009-05-04 18:56:13 +00002417- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

Benjamin Petersond2e0c792009-05-01 20:40:59 +00002422- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
2423 received a new method, detach(). detach() disconnects the underlying stream
2424 from the buffer or text IO and returns it.
2425
Mark Dickinson33841c32009-05-01 15:37:04 +00002426- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
2427 floats with absolute value over 1e50. Also remove length
2428 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
2429 12.34 no longer raise an exception.

2435 never gives more than the requested number of significant digits.
2436
Eric Smith6dc46f52009-04-27 20:39:49 +00002437- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

2443 titlecase, but not their own uppercase.
2444

2446
Mark Dickinsonad476da2009-04-23 19:14:16 +00002447- Issue #5816: complex(repr(z)) now recovers z exactly, even when
2448 z involves nans, infs or negative zeros.
2449
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00002450- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00002451
Mark Dickinsone6a076d2009-04-18 11:48:33 +00002452- Issue #1869 (and many duplicates): make round(x, n) correctly
2453 rounded for a float x, by using the decimal <-> binary conversions
2454 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2455 consistently agrees with format(x, '.2f').
2456
Benjamin Petersonae937c02009-04-18 20:54:08 +00002457- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

2461
Eric Smith35e84722009-04-16 20:21:28 +00002462- Issue #5515: str.format() type 'n' combined with commas and leading
2463 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002464
2465- Implement PEP 378, Format Specifier for Thousands Separator, for
2466 floats.

Mark Dickinson3370cce2009-04-17 22:40:53 +00002468- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002469 1e11, not 1e12. This avoids printing 13 significant digits in
2470 situations where only 12 of them are correct. Example problem
2471 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2472 long time.)
2473
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002474- Issue #1580: On most platforms, use a 'short' float repr: for a
2475 finite float x, repr(x) now outputs a string based on the shortest
2476 sequence of decimal digits that rounds to x. Previous behaviour was
2477 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002478 Another minor difference is that the new repr switches to
2479 exponential notation at 1e16 instead of the previous 1e17; this
2480 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002481
2482 There's a new sys attribute sys.float_repr_style, which takes
2483 the value 'short' to indicate that we're using short float repr,
2484 and 'legacy' if the short float repr isn't available for one
2485 reason or another.
2486
2487 The float repr change involves incorporating David Gay's 'perfect
2488 rounding' code into the Python core (it's in Python/dtoa.c). As a
2489 secondary consequence, all string-to-float and float-to-string
2490 conversions (including all float formatting operations) will be
2491 correctly rounded on these platforms.
2492
Georg Brandl5f90d792010-08-01 22:31:05 +00002493 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002494 this change does not apply.

2497
Georg Brandlabc38772009-04-12 15:51:51 +00002498- The string.maketrans() function is deprecated; there is a new static method
2499 maketrans() on the bytes and bytearray classes. This removes confusion about
2500 the types string.maketrans() is supposed to work with, and mirrors the
2501 methods available on the str class.

2793 rotating the object pointer by 4 bits to the right.
2794
Mark Dickinson87ec0852009-02-09 17:15:59 +00002795- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002807
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002808- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002809 were suppressing all exceptions. These include list() and bytearray().

2815 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2816 evaluation loop is compiled with a new dispatch mechanism which gives
2817 speedups of up to 20%, depending on the system, on various benchmarks.
2818
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002819- Issue #4874: Most builtin decoders now reject unicode input.

2825
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002826- Issue #4838: When a module is deallocated, free the memory backing the
2827 optional module state data.
2828
Mark Dickinson8055afd2009-01-17 10:04:45 +00002829- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2830 type to (void *).
2831
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002832- Issue #4935: The overflow checking code in the expandtabs() method common
2833 to str, bytes and bytearray could be optimized away by the compiler, letting
2834 the interpreter segfault instead of raising an error.
2835
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002836- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2837 __next__ method.
2838
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002839- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2840 function no longer attempt to call the __long__ slot to convert an object
2841 to an integer. Only the __int__ and __trunc__ slots are examined.
2842
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002843- Issue #4893: Use NT threading on CE.
2844

2846
Antoine Pitrouab868312009-01-10 15:40:25 +00002847- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2848 common cases are optimized thanks to a dedicated fast path and a moderate
2849 amount of loop unrolling.
2850
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002851- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2852 collecting the oldest generation) so that allocating lots of objects without
2853 destroying them does not show quadratic performance. Based on a proposal by
2854 Martin von Löwis at
2855 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2856
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002857- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002858 having been closed (for instance, a read() call could return some
2859 previously buffered data). Patch by Dmitry Vasiliev.
2860
Antoine Pitrou05608432009-01-09 18:53:14 +00002861- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2862 flag to work properly. Furthermore, when specifying -u, the text stdout
2863 and stderr streams have line-by-line buffering enabled (the default being
2864 to buffer arbitrary chunks of data).
2865
Raymond Hettinger35631532009-01-09 03:58:09 +00002866- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2867 instead of ints (reducing its size from 4 to 8 times thereby reducing
2868 Python's overall memory).
2869
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002870- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2871 an existing .py counterpart, override the co_filename attributes of all
2872 code objects if the original filename is obsolete (which can happen if the
2873 file has been renamed, moved, or if it is accessed through different paths).
2874 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2875
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002876- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2877 one byte. Also fixes the meaning of len() so that it returns the number of
2878 items, rather than the size in bytes.
2879
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002880- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2881
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002882- Issue #4747: When the terminal does not use utf-8, executing a script with
2883 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2884
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002885- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002886 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002887
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002888- Issue #3680: Reference cycles created through a dict, set or deque iterator
2889 did not get collected.
2890
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002891- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2892 where the tp_hash and tp_dict slots are both NULL.
2893
Georg Brandlccc47b62008-12-28 11:44:14 +00002894- Issue #4759: None is now allowed as the first argument of
2895 bytearray.translate(). It was always allowed for bytes.translate().
2896
Skip Montanaro80072cb2008-12-23 03:51:14 +00002897- Added test case to ensure attempts to read from a file opened for writing
2898 fail.
2899
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002900- Issue #3106: Speedup some comparisons (str/str and int/int).

2904
Antoine Pitrou621601a2008-12-17 23:18:19 +00002905- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2906 print elapsed times, not only when some objects are uncollectable /
2907 unreachable. Original patch by Neil Schemenauer.
2908
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002909- Issue #3439: Add a bit_length method to int.
2910
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002911- Issue #2173: When getting device encoding, check that return value of
2912 nl_langinfo is not the empty string. This was causing silent build
2913 failures on OS X.
2914
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002915- Issue #4597: Fixed several opcodes that weren't always propagating
2916 exceptions.
2917
2918- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002919 context manager returns a value that cannot be converted to a bool.
2920
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002921- Issue #4445: Replace "sizeof(PyBytesObject)" with
2922 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2923 bytes instances. On a typical machine this saves 3 bytes of memory
2924 (on average) per allocation of a bytes instance.
2925
Christian Heimesa872de52008-12-05 08:26:55 +00002926- Issue #4533: File read operation was dreadfully slow due to a slowly
2927 growing read buffer. Fixed by using the same growth rate algorithm as
2928 Python 2.x.
2929
Antoine Pitrou5504e892008-12-06 21:27:53 +00002930- Issue #4509: Various issues surrounding resize of bytearray objects to
2931 which there are buffer exports (e.g. memoryview instances).
2932
Georg Brandlf9734072008-12-07 15:30:06 +00002933- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2934 method on file objects with closefd=False. The file descriptor is still
2935 kept open but the file object behaves like a closed file. The ``FileIO``
2936 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002937
Antoine Pitroubc420402008-12-07 20:14:49 +00002938- Issue #4569: Interpreter crash when mutating a memoryview with an item size
2939 larger than 1.

2944
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002945- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2946 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2947 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2948 of using the replace error handler in PyUnicode_DecodeUTF8().
