Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000223- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
224 start byte and the continuation byte(s) are now considered invalid, instead
225 of the number of bytes specified by the start byte.
226 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
227 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
228 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
229 Previous versions returned a single u'\ufffd'.

239 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +0000558- On Windows, ctypes does no longer check the stack before and after calling a
559 foreign function. This allows to use the unmodified libffi library.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000584 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

Benjamin Peterson5da7e7c2010-03-06 22:44:07 +0000601What's New in Python 2.7 beta 1?
602================================
603
Benjamin Petersonfbac6c12010-04-10 16:22:05 +0000604*Release date: 2010-04-10*
Benjamin Peterson5da7e7c2010-03-06 22:44:07 +0000605
606Core and Builtins
607-----------------
608
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000609- Issue #7301: Add environment variable $PYTHONWARNINGS.
610
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000611- Issue #8329: Don't return the same lists from select.select when no fds are
612 changed.
613
Georg Brandlfee0f442010-05-22 21:26:21 +0000614- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000615 on 64-bit machines. The shift count for either left or right shift is
616 permitted to be up to sys.maxsize.
617
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000618- Ensure that tokenization of identifiers is not affected by locale.
619
Georg Brandlfee0f442010-05-22 21:26:21 +0000620- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +0000621
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000622- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
623
Georg Brandlfee0f442010-05-22 21:26:21 +0000624- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
625 with a non-empty format string. This is an effort to future-proof user
626 code. If a derived class does not currently implement __format__ but later
627 adds its own __format__, it would most likely break user code that had
628 supplied a format string. This will be changed to a DeprecationWaring in
629 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000630
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000631- Issue #8268: Old-style classes (not just instances) now support weak

655
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000656- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000657 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
658 `ssl.OPENSSL_VERSION_NUMBER`.

661
Georg Brandlfee0f442010-05-22 21:26:21 +0000662- Issue #8257: The Decimal construct now accepts a float instance directly,
663 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000664
665 >>> Decimal(1.1)
666 Decimal('1.100000000000000088817841970012523233890533447265625')
667
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000668- collections.Counter() now supports a subtract() method.
669
Georg Brandlfee0f442010-05-22 21:26:21 +0000670- The functools module now has a total_ordering() class decorator to simplify
671 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000672
Georg Brandlfee0f442010-05-22 21:26:21 +0000673- The functools module also adds cmp_to_key() as a tool to transition old-style
674 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +0000675
Georg Brandlfee0f442010-05-22 21:26:21 +0000676- Issue #8294: The Fraction constructor now accepts Decimal and float instances
677 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000678
Georg Brandlfee0f442010-05-22 21:26:21 +0000679- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
680 InvalidOperation instead of returning False. (Comparisons involving a quiet
681 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
682 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000683
Georg Brandlfee0f442010-05-22 21:26:21 +0000684- Issue #2531: Comparison operations between floats and Decimal instances now
685 return a result based on the numeric values of the operands; previously they
686 returned an arbitrary result based on the relative ordering of id(float) and
687 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000688
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000689- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000690 argument `-` which tells it to read files to compile from stdin. Each line is
691 read on demand and the named file is compiled immediately. (Original patch by
692 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000693
Georg Brandlfee0f442010-05-22 21:26:21 +0000694- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +0000697- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
698 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +0000699 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +0000700
Georg Brandlfee0f442010-05-22 21:26:21 +0000701- Comparisons using one of <, <=, >, >= between a complex instance and a
702 Fractions instance now raise TypeError instead of returning True/False. This
703 makes Fraction <=> complex comparisons consistent with int <=> complex, float
704 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +0000705

714
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000715- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +0000716 didn't support chflags() (for example ZFS under FreeBSD). The error is now
717 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000718
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000719- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

Vinay Sajipecfa08f2010-03-12 09:16:10 +0000759- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +0000760 for ``TimedRotatingFileHandler`` by using the modification time of an existing
761 log file to compute the next rollover time. If the log file does not exist,
762 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000763

773 a base64 transfer-encoded payload *after* decoding it; it no longer does.
774 This is a behavior change, so email's minor version number is now bumped, to

809 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
810 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +0000811 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
812 inconsistent: __int__ was used for some integer codes but not for others, and
813 the set of integer codes for which it was used differed between native packing
814 and standard packing.)

Antoine Pitroubb445a12010-02-05 17:05:54 +00001040- Issue #5677: Explicitly forbid write operations on read-only file objects,
1041 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00001042 library would return a bogus result; on Solaris, it was possible to crash the
1043 interpreter. Patch by Stefan Krah.

1054 very large step value.
Mark Dickinson36ecd672010-01-29 17:11:39 +00001055
Georg Brandlba83f822010-03-14 09:50:54 +00001056- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
1057 and add the additional members returned in an OSVERSIONINFOEX structure. The
1058 new members are service_pack_major, service_pack_minor, suite_mask, and
1059 product_type.

Georg Brandlba83f822010-03-14 09:50:54 +00001061- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
1062 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1063 returning NULL. The macro now returns a statically allocated empty string
1064 instead.
Antoine Pitroue80a6a42010-01-17 12:26:20 +00001065

1074 strings,
1075 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
1076 numeric strings corresponding to subnormal values,
1077 (3) a memory leak for some values large enough to cause overflow, and
1078 (4) a number of flaws that could lead to incorrectly rounded results.
1079
1080- Issue #7319, #7770: Silence ``DeprecationWarning`` by default when the -3
1081 option is not used.

1096 interpreter shutdown.
1097
Georg Brandlba83f822010-03-14 09:50:54 +00001098- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
1099 XML processing instructions and comments. These raw characters are allowed
1100 by the XML specification, and are necessary when outputting e.g. PHP code in
1101 a processing instruction. Patch by Neil Muller.

Antoine Pitroud840e512010-02-04 20:20:18 +00001109- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00001110 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00001111 Also, raise ValueError rather than TypeError when an unknown TIPC address
1112 type is specified. Patch by Brian Curtin.
1113
Vinay Sajip28c382f2010-02-04 18:48:53 +00001114- logging: Implemented PEP 391.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001116- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001117 file position when calling `truncate()`. It would previously change the file
1118 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001119 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1120
Georg Brandlba83f822010-03-14 09:50:54 +00001121- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1122 class used to represent files stored inside an archive. The new
1123 implementation is significantly faster and can be wrapped in a
1124 ``io.BufferedReader`` object for more speedups. It also solves an issue
1125 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
1126 Patch by Nir Aides.

Benjamin Petersona43f34c2010-01-25 03:31:13 +00001135
Georg Brandlba83f822010-03-14 09:50:54 +00001136- Issue #7748: Since unicode values are supported for some metadata options in
1137 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1138 encoded string for them. This ensures that the upload and register commands
1139 send the correct values to PyPI without any error.

1214-----------------
1215
Georg Brandlba83f822010-03-14 09:50:54 +00001216- The ``__complex__()`` method is now looked up on the class of instances to
1217 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00001218
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001219- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1220 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1221
Mark Dickinson1b34d252010-01-01 17:27:30 +00001222- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001223 DeprecationWarning when passed a float argument where an integer was expected.
1224 These functions and methods now raise TypeError instead. The majority of the
1225 effects of this change are in the extension modules, but some core functions
1226 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1227 and many unicode/str methods.

1241 of integers: the result of a/b is now correctly rounded for ints a and b (at
1242 least on IEEE 754 platforms), and in particular does not depend on the
1243 internal representation of a long.

Ronald Oussoren92919a62009-12-24 13:30:58 +00001250 executables on OSX.
1251
Georg Brandlba83f822010-03-14 09:50:54 +00001252 These executables now work properly with the arch(1) command: ``arch -ppc
1253 python`` will start a universal binary version of python in PPC mode (unlike
1254 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00001255
Georg Brandlba83f822010-03-14 09:50:54 +00001256- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the

1394 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001395
Georg Brandlba83f822010-03-14 09:50:54 +00001396- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1397 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001398

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001409
Georg Brandlba83f822010-03-14 09:50:54 +00001410- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1411 decimal string that's guaranteed to round back to x under correct rounding
1412 (with round-half-to-even rounding mode). Previously it gave a string based on
1413 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1414 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1415 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001416
Georg Brandlba83f822010-03-14 09:50:54 +00001417- Issue #7117: On almost all platforms: float-to-string and string-to-float
1418 conversions within Python are now correctly rounded. Places these conversions
1419 occur include: str for floats and complex numbers; the float and complex
1420 constructors; old-style and new-style numeric formatting; serialization and
1421 deserialization of floats and complex numbers using marshal, pickle and json;
1422 parsing of float and imaginary literals in Python code; Decimal-to-float
1423 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001424
Georg Brandlba83f822010-03-14 09:50:54 +00001425 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1426 providing correctly-rounded strtod and dtoa C functions. This code is
1427 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1428 the C compiler. There may be a small number of platforms on which correct
1429 operation of this code cannot be guaranteed, so the code is not used: notably,
1430 this applies to platforms where the C double format is not IEEE 754 binary64,
1431 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1432 and Python's configure script is unable to determine how to change the FPU
1433 precision. On these platforms conversions use the platform strtod and dtoa,
1434 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001435
Georg Brandlba83f822010-03-14 09:50:54 +00001436- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1437 uses the correctly-rounded string <-> float conversions described above (when
1438 available), and so produces correctly rounded results that will display nicely
1439 under the float repr. There are two related small changes: (1) round now
1440 accepts any class with an ``__index__()`` method for its second argument (but
1441 no longer accepts floats for the second argument), and (2) an excessively
1442 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1443 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001590- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1591 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1592 but with at least one decimal point and with a default precision
1593 of 12. Previously, the behavior the same but with a default precision of 6.
1594 This more closely matches ``str()``, and reduces surprises when adding
1595 alignment flags to the empty presentation type. This also affects the new
1596 complex.__format__ in the same way.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +00001744- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
1745 file with `str' filename on Windows.
1746
Antoine Pitrouaa687902009-01-01 14:11:22 +00001747- Issue #3680: Reference cycles created through a dict, set or deque iterator
1748 did not get collected.
1749
Georg Brandlba83f822010-03-14 09:50:54 +00001750- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where
1751 the tp_hash and tp_dict slots are both NULL.
Nick Coghlan180e4002008-12-30 01:18:48 +00001752
Benjamin Peterson7af65562008-12-29 17:56:58 +00001753- Issue #4764: With io.open, IOError.filename is set when trying to open a
1754 directory on POSIX systems.
1755
Benjamin Petersonfe231b02008-12-29 17:47:42 +00001756- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
1757 systems.
1758
Georg Brandl6425a2f2008-12-28 11:54:53 +00001759- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00001760 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00001761
Skip Montanarof205c132008-12-23 03:30:15 +00001762- Added test case to ensure attempts to read from a file opened for writing
1763 fail.
1764
Georg Brandlba83f822010-03-14 09:50:54 +00001765- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
1766 elapsed times, not only when some objects are uncollectable/unreachable.
1767 Original patch by Neil Schemenauer.
Antoine Pitrou73c0e652008-12-17 22:46:54 +00001768

1775 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00001776

Georg Brandlba83f822010-03-14 09:50:54 +00001779- Issue #4445: Replace ``sizeof(PyStringObject)`` with
1780 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1781 instances. On a typical machine this saves 3 bytes of memory (on average) per
1782 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00001783
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00001784- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1785 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1786 instead of throwing a MemoryError.
1787
Georg Brandlba83f822010-03-14 09:50:54 +00001788- Issue #3689: The list reversed iterator now supports __length_hint__ instead
1789 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00001790
Benjamin Petersonc078f922008-11-21 22:27:24 +00001791- Issue #4367: Python would segfault during compiling when the unicodedata
1792 module couldn't be imported and \N escapes were present.
1793
Georg Brandlba83f822010-03-14 09:50:54 +00001794- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1795 file objects with closefd=False. The file descriptor is still kept open but
1796 the file object behaves like a closed file. The ``FileIO`` object also got a
1797 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00001798
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00001799- Issue #4348: Some bytearray methods returned that didn't cause any change to
1800 the bytearray, returned the same bytearray instead of a copy.
1801
Georg Brandlba83f822010-03-14 09:50:54 +00001802- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Peterson273c2332008-11-17 22:39:09 +00001804- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1805
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00001806- Issue #4048: The parser module now correctly validates relative imports.
1807
Benjamin Petersondcee09d2008-10-31 02:16:05 +00001808- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1809 exec statement.
1810
Georg Brandlba83f822010-03-14 09:50:54 +00001811- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
1812 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00001813
Benjamin Petersonbdca9422008-10-26 20:21:13 +00001814- Issue #4209: Enabling unicode_literals and the print_function in the same
1815 __future__ import didn't work.
1816
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001817- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00001818 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001819
Georg Brandlba83f822010-03-14 09:50:54 +00001820- On windows, ``os.chdir()`` given unicode was not working if
1821 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1822 this code path is really executed because I cannot move to such directory on
1823 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00001824
Georg Brandlba83f822010-03-14 09:50:54 +00001825- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1826 element is temporarily replaced with an equivalent frozenset. But the
1827 eventual KeyError would always report the empty ``frozenset()`` as the missing
1828 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00001829
Georg Brandlba83f822010-03-14 09:50:54 +00001830- Issue #4509: Various issues surrounding resize of bytearray objects to which
1831 there are buffer exports.

Gregory P. Smithae91d092009-03-02 05:13:57 +00001837- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
1838
Georg Brandlba83f822010-03-14 09:50:54 +00001839- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short

Matthias Kloseedb5e1e2009-04-04 14:18:13 +00001841
Matthias Klose91a3b9e2009-04-05 21:19:13 +00001842- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1843 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00001844
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00001845- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
1846 returned them on 64bit platforms.
1847
Walter Dörwalded960ac2009-05-03 22:36:33 +00001848- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1849 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1850 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1851 of using the replace error handler in PyUnicode_DecodeUTF8().
1852
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001853- Issue #3739: The unicode-internal encoder now reports the number of characters
1854 consumed like any other encoder (instead of the number of bytes).
1855
Georg Brandlba83f822010-03-14 09:50:54 +00001856- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1857 allocator will be automatically disabled when running under Valgrind. This
1858 gives improved memory leak detection when running under Valgrind, while taking
1859 advantage of pymalloc at other times.

Antoine Pitrou4698d992009-05-31 14:20:14 +00003106- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
3107 regression tests in parallel, shortening the total runtime.
3108
Georg Brandlba83f822010-03-14 09:50:54 +00003109- Issue #5354: New test support function import_fresh_module() makes it easy to
3110 import both normal and optimised versions of modules. test_heapq and
3111 test_warnings have been adjusted to use it, tests for other modules with both
3112 C and Python implementations in the stdlib can be adjusted to use it over
3113 time.

Georg Brandlba83f822010-03-14 09:50:54 +00003121- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
3122 should cause a test to be skipped are now done using import_module from test
3123 support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003224- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3225
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003226- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3227 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3228 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3229 ``printf`` function, whereas PyString_FromFormat has an independent
3230 implementation and uses "%zd" on all platforms for size_t values.
3231 This makes a difference on win64, where ``printf`` needs "%Id" to display
3232 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00003234- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3238 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003249 was correctly parsed but parsing of subsequent arguments failed.
3250
Vinay Sajip35e3b032008-09-01 14:33:59 +00003251- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003252 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3253 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3254 when given a tuple of classes as second argument, were looking up
3255 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3256 type object.

3400Core and Builtins
3401-----------------
3402
Guido van Rossumf8402962008-08-20 15:01:50 +00003403- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3404 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3405 extensions do not automatically benefit from the class attribute
3406 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3407 to their tp_flags field if they care. This is a backwards
3408 compatibility feature; in 3.0, all types will use the cache by
3409 default.
3410
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003411- Keyword arguments can now follow starred arguments. (``f(a, *args,
3412 keyword=23)`` is now valid syntax.)
3413
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003414- ctypes function pointers that are COM methods have a boolean True
3415 value again.
3416
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003417- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3418 by denying s# to parse objects that have a releasebuffer procedure,
3419 and introducing s*.
3420
Georg Brandl1e13ea92008-08-11 09:07:59 +00003421- Issue #3537: Fix an assertion failure when an empty but presized dict
3422 object was stored in the freelist.
3423
Mark Dickinsonb6467572008-08-04 21:30:09 +00003424- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3425 ValueError consistently across platforms.
3426
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003427- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3428 (64bit Unix, for example), unichr() would truncate its argument and return
3429 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3430
Neal Norwitze7d8be82008-07-31 17:17:14 +00003431- Apply security patches from Apple.
3432
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003433- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3434 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3435
Antoine Pitrou92f82162008-07-25 22:22:08 +00003436- Issue #1819: function calls with several named parameters are now on
3437 average 35% faster (as measured by pybench).
3438
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003439- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3440 the python debugger steps into a class statement: the free variables (local
3441 variables defined in an outer scope) would be deleted from the outer scope.
3442
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003443- Issue #2620: Overflow checking when allocating or reallocating memory
3444 was not always being done properly in some python types and extension
3445 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3446 all been updated to perform better checks and places in the code that
3447 would previously leak memory on the error path when such an allocation
3448 failed have been fixed.

3451-------
3452
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003453- Issue #3612: Added some missing basic types in ctypes.wintypes.
3454
Benjamin Petersone977ad42008-08-20 01:42:01 +00003455- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3456 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3457
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003458- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3459 version reported by these tools does not necessarily follow the python
3460 version numbering scheme, so the module is less strict when parsing it.
3461
Nick Coghlanf70385a2008-08-18 12:42:46 +00003462- Issue #2235: Added Py3k warnings for types which will become unhashable
3463 under the stricter __hash__ inheritance rules in 3.0. Several types
3464 which did not meet the rules for hash invariants and were already
3465 unhashable in 3.0 have now been explicitly flagged as unhashable in
3466 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3467 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3468
Brett Cannon88f801d2008-08-18 00:46:22 +00003469- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3470 imported into the module but exposed as part of the module's API.
3471
Brett Cannon7b96f072008-08-18 00:41:11 +00003472- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3473
Brett Cannon46225e72008-08-18 00:36:52 +00003474- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
3475
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003476- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3477
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003478- Issue #3575: Incremental decoder's decode function now takes bytearray
3479 by using 's*' instead of 't#'.
3480
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003481- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003482 fails unicode conversion on 2nd parameter. (windows only)
3483
Facundo Batista94f243a2008-08-17 03:38:39 +00003484- Issue 2464. urllib2 now supports a malformation in the URL received
3485 in a redirect.
3486
Brett Cannonabe423e2008-08-16 21:47:07 +00003487- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003488 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003489
Facundo Batistaeb90b782008-08-16 14:44:07 +00003490- Issue #2776: fixed small issue when handling an URL with double slash
3491 after a 302 response in the case of not going through a proxy.
3492
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003493- Issue #2676: in the email package, content-type parsing was hanging on
3494 pathological input because of quadratic or exponential behaviour of a
3495 regular expression.
3496
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003497- Issue #3476: binary buffered reading through the new "io" library is now
3498 thread-safe.
3499
Brett Cannonbf3157b2008-08-14 05:00:03 +00003500- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3501 since mimetools itself is deprecated. Because modules are cached, all
3502 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3503
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003504- Issue #3134: shutil referenced undefined WindowsError symbol.
3505
Robert Schuppenies14646332008-08-10 11:01:53 +00003506- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3507 menu entries were not deleted.
3508
Brett Cannon83e81842008-08-09 23:30:55 +00003509- Copied the implementation of reduce() to _functools.reduce() to have a
3510 version that did not raise a DeprecationWarning under -3.
3511
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003512- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3513 a MemoryError rather than silently stop the iteration.
3514
Guido van Rossum59ce9012008-08-09 14:55:34 +00003515- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3516 to _sre.compile() will now be rejected. This should not affect anybody
3517 since the re.compile() function never generates invalid re-bytecode.
3518
Skip Montanaroa032bf42008-08-08 22:52:51 +00003519- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3520 upon first access it can be automatically initialized from the csv file if
3521 it wasn't initialized during instantiation.
3522
Brett Cannon3aa2a492008-08-06 22:28:09 +00003523- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3524 the reload() built-in has been removed.
3525
Brett Cannon7e30b672008-08-04 21:52:25 +00003526- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003527 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00003528 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
3529 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
3530 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
3531 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
3532 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00003533
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00003534- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
3535 raised an AttributeError.
3536
Benjamin Peterson01a24322008-07-28 23:35:27 +00003537- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003538 asking for a specific length. This problem only affected files opened
3539 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003540
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003541- Issue #3449: Update decimal module to use most recent specification
3542 (v. 1.68) and tests (v. 2.58) from IBM.
3543
Skip Montanarof9ac43f2008-07-27 00:50:41 +00003544- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
3545
Raymond Hettinger8c664e82008-07-25 18:43:33 +00003546- Issue 1592: Improve error reporting when operations are attempted
3547 on a closed shelf.
3548
Georg Brandlf9efabb2008-07-23 15:16:45 +00003549- Deprecate the "ast" parser function aliases.
3550
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003551- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
3552
3553- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3554 invalid arguments.
3555
3556- Issue #3302: Fix several crashes when calling locale's gettext functions
3557 with None arguments.
3558
3559- Issue #3389: Allow resolving dotted names for handlers in logging
3560 configuration files.
3561
3562- Deprecate the sunaudio module for removal in Python 3.0.
3563
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003564- Issue #3394: zipfile.writestr sets external attributes when passed a
3565 file name rather than a ZipInfo instance, so files are extracted with
3566 mode 0600 rather than 000 under Unix.
3567
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003568- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3569 argument in python 2.5, this broke code that subclassed Popen to include its
3570 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3578-------------
3579
Nick Coghlan6e8fef02008-08-18 13:14:22 +00003580- Issue #2235: the C API function PyObject_HashNotImplemented and its
3581 interaction with the tp_hash slot (added in 2.6b2) are now documented
3582
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003583- Issue #643841: The language reference now provides more detailed
3584 coverage of the lookup process for special methods. The disclaimers
3585 regarding lack of coverage of new-style classes have also been
3586 removed, since the coverage is now fairly reasonable.

3595-----------------
3596
Georg Brandl3e483f62008-07-16 22:57:41 +00003597- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3598 its methods now allow for items objects that can be converted to
3599 an integer using operator.index().
3600
Mark Dickinson64b7e502008-07-16 09:40:03 +00003601- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3602 produced a ValueError instead of giving the correct float.
3603
Eric Smitha5fa5a22008-07-16 00:11:49 +00003604- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3605 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3606
Mark Dickinson7103aa42008-07-15 19:08:33 +00003607- Issue #3008: the float type has a new instance method 'float.hex'
3608 and a new class method 'float.fromhex' to convert floating-point
3609 numbers to and from hexadecimal strings, respectively.
3610
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003611- Issue #2235: __hash__ is once again inherited by default. To allow
3612 collections.Hashable to remain meaningful in the presence of the
3613 default hash implementation (object.__hash__), it is now possible
3614 to explicit block inheritance of hash by setting __hash__=None at
3615 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3616 level.
3617
Nick Coghlanb028f502008-07-13 14:52:36 +00003618- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3619 the parent module cannot be found while performing an absolute import.
3620 This means that an incorrectly defined __package__ attribute will
3621 now only prevent relative imports in that module rather than causing
3622 all imports from that module to fail.
3623
Nick Coghlan14ff9942008-07-08 14:21:42 +00003624- Issue #2517: Allow unicode messages in Exceptions again by correctly
3625 bypassing the instance dictionary when looking up __unicode__ on
3626 new-style classes.
3627
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003628- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3629 set to a custom object whose write() method happens to install
3630 another file in sys.stdout.
3631
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003632- Issue #3088: Corrected a race condition in classes derived from
3633 threading.local: the first member set by a thread could be saved in
3634 another thread's dictionary.
3635
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003636- Issue #3004: Minor change to slice.indices(): the start and stop
3637 arguments are now treated identically, making the behaviour easier
3638 to describe and understand. For example, slice(None, -10,
3639 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3640 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3641 10, -1).
3642
Georg Brandl278fc502008-07-19 12:46:12 +00003643- Issue #3219: Calling a function with repeated keyword arguments,
3644 f(a=2, a=23), would not cause a syntax error. This was a regression
3645 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003646
Georg Brandl278fc502008-07-19 12:46:12 +00003647- Issue #2862: Make int and float freelist management consistent with
3648 other freelists. Changes their CompactFreeList apis into
3649 ClearFreeList apis and calls them via gc.collect().

3652-------
3653
Thomas Heller57adf222008-08-14 19:10:48 +00003654- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3655 api functions without holding the GIL, which could lead to a fatal
3656 error when they failed.
3657
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003658- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00003666- Issue #3125: Remove copy_reg in multiprocessing and replace it with
3667 ForkingPickler.register() to resolve conflict with ctypes.
3668
Vinay Sajip51e65192008-07-18 09:01:10 +00003669- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00003670
Thomas Heller880f5292008-07-15 19:39:38 +00003671- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3672 a valid dlerror() message.
3673
Thomas Heller2bad6572008-07-15 17:19:50 +00003674- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3675 incomplete structure was created.
3676
Brett Cannon3d0b9f02008-07-13 01:15:07 +00003677- Issue #3339: dummy_thread.acquire() should not return None.
3678
Raymond Hettingerb01713e2008-07-10 14:34:57 +00003679- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
3680
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003681- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003682
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003683- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3684 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003685 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003686 content-length. The problem had been corrected in the 2.4 branch, but never

4094 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004095 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004096
4097 This is controlled by the configure argument ``--with-universal-archs``:
4098
4099 - ``--with-universal-archs=all``: install 4-way universal
4100
4101 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4102
4103 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4104
4105 This option should be used in combination with ``--enable-universalsdk=``.
4106
4107 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00004157- Issue #1631171: Re-implement the 'warnings' module in C (the
4158 original Python code has been kept as backup). This will allow for
4159 using the 'warning's machinery in such places as the parser where
4160 use of pure Python code is not possible. Both the ``showarning()``
4161 and ``formatwarning()`` gain an optional 'line' argument which is
4162 not called by default for backwards-compatibility reasons. Setting
4163 ``warnings.showwarning()`` to an implementation that lacks support
4164 for the ``line`` argument will raise a DeprecationWarning.

4188
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004189- The getpass module has been improved on Unix. It now uses /dev/tty
4190 by default and uses stderr instead of stdout. A GetPassWarning is
4191 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004206- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004207 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004227- Issue #2550: The approach used by client/server code for obtaining
4228 ports to listen on in network-oriented tests has been refined in an
4229 effort to facilitate running multiple instances of the entire
4230 regression test suite in parallel without issue.
4231 test_support.bind_port() has been fixed such that it will always
4232 return a unique port -- which wasn't always the case with the
4233 previous implementation, especially if socket options had been set
4234 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4235 new implementation of bind_port() will actually raise an exception
4236 if it is passed an AF_INET/SOCK_STREAM socket with either the
4237 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4238 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4239 the socket it's been passed. This currently only applies to
4240 Windows. This option prevents any other sockets from binding to the
4241 host/port we've bound to, thus removing the possibility of the
4242 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4243 when a second SOCK_STREAM socket binds and accepts to a host/port
4244 that's already been bound by another socket. The optional preferred
4245 port parameter to bind_port() has been removed. Under no
4246 circumstances should tests be hard coding ports!
4247
4248 test_support.find_unused_port() has also been introduced, which will
4249 pass a temporary socket object to bind_port() in order to obtain an
4250 unused port. The temporary socket object is then closed and
4251 deleted, and the port is returned. This method should only be used
4252 for obtaining an unused port in order to pass to an external program
4253 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4254 a parameter to a server-oriented class that doesn't give you direct
4255 access to the underlying socket used.
4256
4257 Finally, test_support.HOST has been introduced, which should be used
4258 for the host argument of any relevant socket calls (i.e. bind and
4259 connect).

4533Core and builtins
4534-----------------
4535
Fred Drakea8ee94b2008-03-01 02:45:07 +00004536- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004537 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004538
Georg Brandlad61bc82008-02-23 15:11:18 +00004539- Issue #2067: file.__exit__() now calls subclasses' close() method.
4540
4541- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004542
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004543- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004544 issue 215555 for a discussion.
4545
Eric Smitha73fbe72008-02-23 03:09:44 +00004546- Added the future_builtins module, which contains hex() and oct().
4547 These are the PEP 3127 version of these functions, designed to be
4548 compatible with the hex() and oct() builtins from Python 3.0. They
4549 differ slightly in their output formats from the existing, unchanged
4550 Python 2.6 builtins. The expected usage of the future_builtins
4551 module is:
4552 from future_builtins import hex, oct
4553
Eric Smith7ef40bf2008-02-20 23:34:22 +00004554- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4555 exponents for exponents with absolute value < 100. Follows C99
4556 standard. This is a change on Windows, which would use 3 digits.
4557 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4558 so that any alterations it does to the resulting string will be
4559 available in stringlib/formatter.h (for float.__format__).
4560
Eric Smith5a3c1352008-02-19 13:21:56 +00004561- Implemented PEP 3101, Advanced String Formatting. This adds a new
4562 builtin format(); a format() method for str and unicode; a
4563 __format__() method to object, str, unicode, int, long, float, and
4564 datetime; the class string.Formatter; and the C API
4565 PyObject_Format().
4566
Georg Brandl3ee81df2008-05-17 18:14:43 +00004567- Fixed several potential crashes, all caused by specially crafted
4568 __del__ methods exploiting objects in temporarily inconsistent
4569 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004570
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004571- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004572 prevent a possible crash: an Abstract Base Class would try to access
4573 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004574
Georg Brandl3ee81df2008-05-17 18:14:43 +00004575- Fixed repr() and str() of complex numbers with infinity or nan as
4576 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004577
Georg Brandl3ee81df2008-05-17 18:14:43 +00004578- Clear all free lists during a gc.collect() of the highest generation
4579 in order to allow pymalloc to free more arenas. Python may give back
4580 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004581
Georg Brandl3ee81df2008-05-17 18:14:43 +00004582- Issue #2045: Fix an infinite recursion triggered when printing a
4583 subclass of collections.defaultdict, if its default_factory is set
4584 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004585
Christian Heimesf75dbef2008-02-08 00:11:31 +00004586- Fixed a minor memory leak in dictobject.c. The content of the free
4587 list was not freed on interpreter shutdown.
4588
Georg Brandl21e99f42010-03-07 15:23:59 +00004589- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004590 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004591
Georg Brandl3ee81df2008-05-17 18:14:43 +00004592- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4593 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004594 to compact the internal free lists of pre-allocted ints and floats.
4595
Georg Brandl3ee81df2008-05-17 18:14:43 +00004596- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4597 calls. Python expected the return type int but the fork familie
4598 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004599
Georg Brandl3ee81df2008-05-17 18:14:43 +00004600- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4601 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004602
Georg Brandl3ee81df2008-05-17 18:14:43 +00004603- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4604 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004605
Georg Brandl3ee81df2008-05-17 18:14:43 +00004606- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4607 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004608
Georg Brandl3ee81df2008-05-17 18:14:43 +00004609- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4610 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004611
Georg Brandl3ee81df2008-05-17 18:14:43 +00004612- Patch #1473257: generator objects gain a gi_code attribute. This is
4613 the same object as the func_code attribute of the function that
4614 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004615
Georg Brandl3ee81df2008-05-17 18:14:43 +00004616- Issue #1920: "while 0" statements were completely removed by the
4617 compiler, even in the presence of an "else" clause, which is
4618 supposed to be run when the condition is false. Now the compiler
4619 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004620
Guido van Rossumeead05f2008-01-24 18:21:02 +00004621- A few crashers fixed: weakref_in_del.py (issue #1377858);
4622 loosing_dict_ref.py (issue #1303614, test67.py);
4623 borrowed_ref_[34].py (not in tracker).
4624
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004625- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004626 suppressed while an extension is loaded by calling SetErrorMode in
4627 dynload_win.c. The error is still reported properly.
4628
Georg Brandl3ee81df2008-05-17 18:14:43 +00004629- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004630 several extension methods and modules do not work without unicode
4631 support.
4632
Georg Brandl26543b12008-01-21 18:36:51 +00004633- Issue #1882: when compiling code from a string, encoding cookies in the
4634 second line of code were not always recognized correctly.
4635
Georg Brandl14404b62008-01-19 19:27:05 +00004636- Issue #1679: "0x" was taken as a valid integer literal.
4637
Georg Brandl6caad7d2008-01-26 14:19:22 +00004638- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004639 added.
4640
Christian Heimesc94e2b52008-01-14 04:13:37 +00004641- sys.float_info / PyFloat_GetInfo: The floating point information
4642 object was converted from a dict to a specialized structseq object.
4643
Georg Brandl3ee81df2008-05-17 18:14:43 +00004644- Patch #1816: Added sys.flags structseq. It exposes the status of
4645 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004646
Georg Brandl3ee81df2008-05-17 18:14:43 +00004647- Objects/structseq.c: Implemented new structseq representation. The
4648 patch makes structseqs (e.g. the return value of os.stat) more
4649 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004650
Georg Brandl3ee81df2008-05-17 18:14:43 +00004651- Patch #1700288: added a type attribute cache that caches method
4652 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004653
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004654- Bug #1776: __import__() no longer accepts filenames on any platform.
4655 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004656
Georg Brandlaed6c662008-01-07 17:25:53 +00004657- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4658
Georg Brandl3ee81df2008-05-17 18:14:43 +00004659- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4660 envvar and sys.dont_write_bytecode attribute. All these can be set
4661 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004662
Georg Brandl3ee81df2008-05-17 18:14:43 +00004663- Improve some exception messages when Windows fails to load an
4664 extension module. Now we get for example '%1 is not a valid Win32
4665 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004666
Georg Brandl3ee81df2008-05-17 18:14:43 +00004667- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004669- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4670 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004671
Christian Heimes0a8143f2007-12-18 23:22:54 +00004672- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004673 and INF. float("nan"), float("inf") and float("-inf") now work on
4674 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004675
Georg Brandl3ee81df2008-05-17 18:14:43 +00004676- Compiler now generates simpler and faster code for dictionary
4677 literals. The oparg for BUILD_MAP now indicates an estimated
4678 dictionary size. There is a new opcode, STORE_MAP, for adding
4679 entries to the dictionary.

4691
Nick Coghlanef01d822007-12-03 12:55:17 +00004692- PEP 366: Allow explicit relative imports when executing modules
4693 inside packages with the -m switch via a new module level
4694 __package__ attribute.
4695
Georg Brandl3ee81df2008-05-17 18:14:43 +00004696- Issue #1402: Fix a crash on exit, when another thread is still
4697 running, and if the deallocation of its frames somehow calls the
4698 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004699

4709 file can now be directly executed by passing their name to the
4710 interpreter. The directory/zipfile is automatically inserted as the
4711 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004712
Georg Brandl3ee81df2008-05-17 18:14:43 +00004713- Issue #1265: Fix a problem with sys.settrace, if the tracing
4714 function uses a generator expression when at the same time the
4715 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004716
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004717- sets and frozensets now have an isdisjoint() method.
4718
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004719- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00004721- Fix warnings found by the new version of the Coverity checker.
4722
Georg Brandl21e99f42010-03-07 15:23:59 +00004723- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004724 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4725 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004726
Georg Brandl3ee81df2008-05-17 18:14:43 +00004727- Issue #1686386: Tuple's tp_repr did not take into account the
4728 possibility of having a self-referential tuple, which is possible
4729 from C code. Nor did object's tp_str consider that a type's tp_str
4730 could do something that could lead to an inifinite recursion.
4731 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4732 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004733
Georg Brandl3ee81df2008-05-17 18:14:43 +00004734- Issue #1164: It was possible to trigger deadlock when using the
4735 'print' statement to write to a file since the GIL was not released
4736 as needed. Now PyObject_Print() does the right thing along with
4737 various tp_print implementations of the built-in types and those in
4738 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004739
Georg Brandl3ee81df2008-05-17 18:14:43 +00004740- Issue #1147: Exceptions were directly allowing string exceptions in

Georg Brandl3ee81df2008-05-17 18:14:43 +00004748 PyObject_Call() never calling back out to Python code to trigger
4749 recursion depth updates/checks. Required the creation of a static
4750 RuntimeError instance in case normalizing an exception put the
4751 recursion check value past its limit. Fixes crashers
4752 infinite_rec_(1|2|4|5).py.

4758 with %G.
4759
Georg Brandl3ee81df2008-05-17 18:14:43 +00004760- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00004767- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004768 __*__ attributes. (Some already existed, e.g., __doc__ and
4769 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004770
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004771- Add -3 option to the interpreter to warn about features that are
4772 deprecated and will be changed/removed in Python 3.0.
4773
Georg Brandl2134e752007-05-21 20:34:16 +00004774- Patch #1686487: you can now pass any mapping after '**' in function
4775 calls.
4776
Collin Winter62903052007-05-18 23:11:24 +00004777- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004778 "except E as target:". This is to provide forwards compatibility
4779 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004780
Brett Cannon229cee22007-05-05 01:34:02 +00004781- Deprecate BaseException.message as per PEP 352.
4782
Georg Brandl3ee81df2008-05-17 18:14:43 +00004783- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004784 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004785
Vinay Sajip8549ce32007-05-06 17:53:37 +00004786- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004787 setting a plain string, ie don't expand to single letter identifiers.
4788
Raymond Hettinger13936692007-04-11 18:40:58 +00004789- Request #1191699: Slices can now be pickled.
4790
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004791- Request #1193128: str.translate() now allows a None argument for
4792 translations that only remove characters without re-mapping the
4793 remaining characters.
4794
Georg Brandl5cb76c12007-03-21 09:00:39 +00004795- Patch #1682205: a TypeError while unpacking an iterable is no longer
4796 masked by a generic one with the message "unpack non-sequence".
4797
Neal Norwitzaa754b72007-03-21 06:39:48 +00004798- Remove unused file Python/fmod.c.
4799
Guido van Rossum143b5642007-03-23 04:58:42 +00004800- Bug #1683368: The object.__init__() and object.__new__() methods are
4801 now stricter in rejecting excess arguments. The only time when
4802 either allows excess arguments is when it is not overridden and the
4803 other one is. For backwards compatibility, when both are
4804 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004805 warning later). Also, type.__init__() insists on the same signature
4806 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004807
Georg Brandl3ee81df2008-05-17 18:14:43 +00004808- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4809 object to complex using its __complex__() method before falling back
4810 to the __float__() method. Therefore, the functions in the cmath
4811 module now can operate on objects that define a __complex__()
4812 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004813
Georg Brandl3ee81df2008-05-17 18:14:43 +00004814- Patch #1623563: allow __class__ assignment for classes with
4815 __slots__. The old and the new class are still required to have the
4816 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004817

4822 ``object.__reduce_ex__()`` is called with an object that is faking
4823 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004824
Georg Brandl3ee81df2008-05-17 18:14:43 +00004825- Patch #1680015: Don't modify __slots__ tuple if it contains an

4829
Georg Brandl7b9c5552007-03-12 14:30:05 +00004830- Bug #1678647: write a newline after printing an exception in any
4831 case, even when converting the value to a string failed.
4832
Georg Brandl871f1bc2007-03-12 13:17:36 +00004833- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004834 its argument, if it exists. If not, it will work like before. This
4835 allows customizing the output of dir() in the presence of a
4836 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004837
Collin Winter276887b2007-03-12 16:11:39 +00004838- Patch #922167: Python no longer segfaults when faced with infinitely
4839 self-recursive reload() calls (as reported by bug #742342).
4840

4845 parthensized forms. This means complex(repr(x)) now works instead of
4846 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004847
Georg Brandlaa2321b2007-03-07 00:40:28 +00004848- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004849 makes the filenames the warning module prints much more sensible
4850 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004851
Georg Brandl49aafc92007-03-07 00:34:46 +00004852- Variant of patch #697613: don't exit the interpreter on a SystemExit
4853 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004854 variable is given, but break into the interactive interpreter just
4855 like on other exceptions or normal program exit.

4861 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00004862
Georg Brandl0fca97a2007-03-05 22:28:08 +00004863- Patch #1674228: when assigning a slice (old-style), check for the
4864 sq_ass_slice instead of the sq_slice slot.
4865
Georg Brandl3ee81df2008-05-17 18:14:43 +00004866- When printing an unraisable error, don't print exceptions. before
4867 the name. This duplicates the behavior whening normally printing
4868 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004876- Bug #1377858: Fix the segfaulting of the interpreter when an object
4877 created a weakref on itself during a __del__ call for new-style
4878 classes (classic classes still have the bug).

5477 Python would crash instead of raising an error.
5478

Georg Brandl3ee81df2008-05-17 18:14:43 +00005492- unittest now verifies more of its assumptions. In particular,
5493 TestCase and TestSuite subclasses (not instances) are no longer
5494 accepted in TestSuite.addTest(). This should cause no
5495 incompatibility since it never made sense with ordinary subclasses
5496 -- the failure just occurred later, with a more cumbersome
5497 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005778- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5779 with RFC 3207 and forgets any knowledge obtained from the server not
5780 obtained from the TLS negotiation itself. Patch contributed by Bill
5781 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005782
Georg Brandl3ee81df2008-05-17 18:14:43 +00005783- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005784 that the SMTP.starttls() caller no longer needs to call ehlo()
5785 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005786 does not claim to support starttls. Adds the
5787 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5868 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5869 silently miscode subclasses of those types. Now, it raises a
5870 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005871

Georg Brandl3ee81df2008-05-17 18:14:43 +00005886 time so that opening a database previously created with the DB_DUP
5887 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5888 opens. Specifically: dictionary assignment to a DB object will
5889 replace all values for a given key when the database allows
5890 duplicate values. DB users should use DB.put(k, v) when they want
5891 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005892

5898 characters with ASCII value less than 32. Also, it correctly quotes
5899 dots only if they occur on a single line, as opposed to the previous
5900 behavior of quoting dots if they are the second character of any
5901 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005902

Neal Norwitz92422fb2006-08-18 03:57:54 +00006223C API
6224-----
6225
Georg Brandl3ee81df2008-05-17 18:14:43 +00006226- Unified naming convention for free lists and their limits. All free
6227 lists in Object/ are named ``free_list``, the counter ``numfree``
6228 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
6229 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00006230
Georg Brandl3ee81df2008-05-17 18:14:43 +00006231- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6232 to ``PyTuple_SetItem``, it can be used to populate a brand new
6233 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00006234
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006235- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006237- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
6238 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
6239 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006240
6241- Patch #1720595: add T_BOOL to the range of structmember types.
6242
6243- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
6244 ``PyFloat_GetInfo()`` to the float API.
6245
Georg Brandl3ee81df2008-05-17 18:14:43 +00006246- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6247 of w# format code incorrectly truncated the length to an int, even
6248 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6249 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006250
Georg Brandl3ee81df2008-05-17 18:14:43 +00006251- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
6252 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006254- PEP 3123: Provide forward compatibility with Python 3.0, while
6255 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
6256 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006257
Georg Brandl3ee81df2008-05-17 18:14:43 +00006258- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
6259 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006260
6261- Patch #1733960: Allow T_LONGLONG to accept ints.
6262
6263- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
6264
Christian Heimes000a0742008-01-03 22:16:32 +00006265- Added a new API function ``PyImport_ImportModuleNoBlock``.

6268
6269- Fix some leftovers from the conversion from int to Py_ssize_t
6270 (relevant to strings and sequences of more than 2**31 items).
6271
6272- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6273 outside of pystate.c and should not be necessary.
6274
Georg Brandl3ee81df2008-05-17 18:14:43 +00006275- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6276 absolute imports. In earlier versions they might have used relative
6277 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006278
Georg Brandl3ee81df2008-05-17 18:14:43 +00006279- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6280 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006281
Georg Brandl3ee81df2008-05-17 18:14:43 +00006282- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
6283 macro so it can be used as an expression.

6288
Georg Brandl3ee81df2008-05-17 18:14:43 +00006289- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
6290 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6291 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6292 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00006293
Georg Brandl3ee81df2008-05-17 18:14:43 +00006294- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Brett Cannon791d56f2007-05-31 19:40:42 +00006305- buildtools now raises a DeprecationWarning.
6306
Georg Brandl3ee81df2008-05-17 18:14:43 +00006307- Removed the macfs module. It had been deprecated since Python 2.5.
6308 This lead to the deprecation of macostools.touched() as it relied
6309 solely on macfs and was a no-op under OS X.
