Benjamin Petersone3c10452010-07-03 14:51:25 +00007What's New in Python 2.7.1?
8===========================

13-----------------
14
Antoine Pitrou0a7b65b2010-09-08 12:40:49 +000015- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
16 thread-local storage key.
17
Victor Stinnercaafd772010-09-08 10:51:01 +000018- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
19 encoding and errors attributes instead of using utf-8 in strict mode, to get
20 the same behaviour than the print statement.
21
Antoine Pitrou9cf85f12010-09-01 21:17:34 +000022- Issue #9737: Fix a crash when trying to delete a slice or an item from
23 a memoryview object.
24
Martin v. Löwis6086b0d2010-08-19 09:09:04 +000025- Restore GIL in nis_cat in case of error.
26
Benjamin Peterson6f3d6a92010-08-25 23:17:42 +000027- Issue #9688: __basicsize__ and __itemsize__ must be accessed as Py_ssize_t.
28
Florent Xicluna172e15f2010-08-09 20:02:00 +000029- Issue #8530: Prevent stringlib fastsearch from reading beyond the front
30 of an array.
31
Raymond Hettinger3ad323e2010-08-06 10:18:56 +000032- Issue #83755: Implicit set-to-frozenset conversion was not thread-safe.
33
Mark Dickinsonaad57bd2010-08-01 10:45:15 +000034- Issue #9416: Fix some issues with complex formatting where the
35 output with no type specifier failed to match the str output:
36
37 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
38 - format(complex(0.0, 2.0), '-') included a sign and parentheses.
39
Antoine Pitrou32669782010-07-11 12:14:05 +000040- Issue #7616: Fix copying of overlapping memoryview slices with the Intel

45
Antoine Pitroue4195e82010-09-12 14:56:27 +000046- Issue #9837: The read() method of ZipExtFile objects (as returned by
47 ZipFile.open()) could return more bytes than requested.
48
Raymond Hettinger20397532010-09-12 02:11:45 +000049- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
50 This prevents user-created self-referencing ordered dictionaries from
51 becoming permanently uncollectable GC garbage. The downside is that
52 removing __del__ means that the internal doubly-linked list has to wait for
53 GC collection rather than freeing memory immediately when the refcnt drops
54 to zero.
55
Raymond Hettingerffd2a422010-09-10 10:47:22 +000056- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
57 different internal state for small values of n. Fixed by salting the
58 value.
59
Antoine Pitrouc818ed42010-09-07 21:40:25 +000060- Issue #9792: In case of connection failure, socket.create_connection()
61 would swallow the exception and raise a new one, making it impossible
62 to fetch the original errno, or to filter timeout errors. Now the
63 original error is re-raised.
64
Antoine Pitrouf4f61712010-09-07 16:34:47 +000065- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
66 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
67 be updated back after the system call. Original patch by Brian Brazil.
68
Antoine Pitroudca9de92010-09-04 17:52:26 +000069- Issue #1100562: Fix deep-copying of objects derived from the list and
70 dict types. Patch by Michele Orrù and Björn Lindqvist.
71
Fred Drakea1e627d2010-09-03 03:55:50 +000072- Issue #7005: Fixed output of None values for RawConfigParser.write and
73 ConfigParser.write.
74
Daniel Stutzbach66c981b2010-08-31 20:29:39 +000075- Issue #808164: Fixed socket.close to avoid references to globals, to
76 avoid issues when socket.close is called from a __del__ method.
77
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +000078- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
79 falling into recursion.
80
R. David Murray7c4bf552010-08-25 01:45:57 +000081- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
82 character years even if the message contains RFC822 two character years.
83
Daniel Stutzbach91287322010-08-24 21:09:30 +000084- Issue #8750: Fixed MutableSet's methods to correctly handle
85 reflexive operations, namely x -= x and x ^= x.
86
Victor Stinnercaafd772010-09-08 10:51:01 +000087- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing
Giampaolo Rodolà8664d742010-08-23 22:48:51 +000088 error handling when accepting a new connection.
89
Giampaolo Rodolà63308d72010-08-23 21:58:47 +000090- Issue #658749: asyncore's connect() method now correctly interprets winsock
91 errors.
92
Vinay Sajip1ddd51f2010-08-23 17:50:30 +000093- Issue #9501: Fixed logging regressions in cleanup code.
94

96 module now correctly return a set. (Patch by Eli Bendersky.)
97
Antoine Pitrou3ebaed62010-08-21 19:17:25 +000098- Issue #9617: Signals received during a low-level write operation aren't
99 ignored by the buffered IO layer anymore.
100
Benjamin Peterson52c36052010-08-21 03:03:22 +0000101- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
102 are not held onto after they are deleted elsewhere.
103
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000104- Issue #9626: the view methods for collections.OrderedDict() were returning
105 the unordered versions inherited from dict. Those methods are now
106 overridden to provide ordered views.
107
Éric Araujo0389ae62010-08-14 03:07:46 +0000108- Issue #8688: MANIFEST files created by distutils now include a magic
109 comment indicating they are generated. Manually maintained MANIFESTs
110 without this marker will not be overwritten or removed.
111
Antoine Pitroue1436d12010-08-12 15:25:51 +0000112- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
113 and a BadZipfile error is raised if it doesn't match (as used to be the
114 case in Python 2.5 and earlier).
115
Antoine Pitroucb4f47c2010-08-11 13:40:17 +0000116- Issue #9550: a BufferedReader could issue an additional read when the
117 original read request had been satisfied, which could block indefinitely
118 when the underlying raw IO channel was e.g. a socket. Report and original
119 patch by Jason V. Miller.
120
Fred Drake0a1fa0e2010-08-10 13:09:54 +0000121- Issue #9551: Don't raise TypeError when setting the value to None for

125 Interpreter Lock around all system calls. Original patch by Ryan Kelly.
126
Antoine Pitrou99009162010-08-09 22:51:24 +0000127- Issue #3757: thread-local objects now support cyclic garbage collection.
128 Thread-local objects involved in reference cycles will be deallocated
129 timely by the cyclic GC, even if the underlying thread is still running.
130
Florent Xicluna2f1b1ff2010-08-09 20:46:49 +0000131- Issue #6231: Fix xml.etree.ElementInclude to include the tail of the

140 This is how it is supposed to work, wget and curl do the same. Previous
141 behavior was wrong.
142

475 start byte and the continuation byte(s) are now considered invalid, instead
476 of the number of bytes specified by the start byte.
477 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and

490 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +0000632- Issue #1533: Fix inconsistency in range function argument processing: any
633 non-float non-integer argument is now converted to an integer (if possible)
634 using its __int__ method. Previously, only small arguments were treated this

687 operation raises multiple signals and more than one of those signals is
688 trapped, the specification determines the order in which the signals should be
689 handled. In many cases this order wasn't being followed, leading to the wrong
690 Python exception being raised.

858-----------------
859
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000860- Issue #7301: Add environment variable $PYTHONWARNINGS.
861
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000862- Issue #8329: Don't return the same lists from select.select when no fds are
863 changed.
864
Georg Brandlfee0f442010-05-22 21:26:21 +0000865- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000866 on 64-bit machines. The shift count for either left or right shift is
867 permitted to be up to sys.maxsize.
868
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000869- Ensure that tokenization of identifiers is not affected by locale.
870
Georg Brandlfee0f442010-05-22 21:26:21 +0000871- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +0000872
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000873- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
874
Georg Brandlfee0f442010-05-22 21:26:21 +0000875- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
876 with a non-empty format string. This is an effort to future-proof user
877 code. If a derived class does not currently implement __format__ but later
878 adds its own __format__, it would most likely break user code that had
879 supplied a format string. This will be changed to a DeprecationWaring in
880 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000881
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000882- Issue #8268: Old-style classes (not just instances) now support weak
883 references.
884
Georg Brandlfee0f442010-05-22 21:26:21 +0000885- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
886 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +0000887
Victor Stinnerc7790ed2010-03-22 12:36:28 +0000888- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +0000889
Benjamin Peterson96545892010-03-21 20:21:00 +0000890- Issue #6474: Make error message from passing an inadequate number of keyword
891 arguments to a function correct.
892
Benjamin Peterson0dee9c12010-03-17 20:41:42 +0000893- Issue #8164: Don't allow lambda functions to have a docstring.
894
Victor Stinner66644262010-03-10 22:30:19 +0000895- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +0000896 (SIGINT). If an error occurs while importing the site module, the error is
897 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +0000898 module.

906
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000907- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000908 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
909 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000910

Georg Brandlfee0f442010-05-22 21:26:21 +0000913- Issue #8257: The Decimal construct now accepts a float instance directly,
914 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000915
916 >>> Decimal(1.1)
917 Decimal('1.100000000000000088817841970012523233890533447265625')
918
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000919- collections.Counter() now supports a subtract() method.
920
Georg Brandlfee0f442010-05-22 21:26:21 +0000921- The functools module now has a total_ordering() class decorator to simplify
922 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000923
Georg Brandlfee0f442010-05-22 21:26:21 +0000924- The functools module also adds cmp_to_key() as a tool to transition old-style
925 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +0000926
Georg Brandlfee0f442010-05-22 21:26:21 +0000927- Issue #8294: The Fraction constructor now accepts Decimal and float instances
928 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000929
Georg Brandlfee0f442010-05-22 21:26:21 +0000930- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
931 InvalidOperation instead of returning False. (Comparisons involving a quiet
932 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
933 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000934
Georg Brandlfee0f442010-05-22 21:26:21 +0000935- Issue #2531: Comparison operations between floats and Decimal instances now
936 return a result based on the numeric values of the operands; previously they
937 returned an arbitrary result based on the relative ordering of id(float) and
938 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000939
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000940- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000941 argument `-` which tells it to read files to compile from stdin. Each line is
942 read on demand and the named file is compiled immediately. (Original patch by
943 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000944
Georg Brandlfee0f442010-05-22 21:26:21 +0000945- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +0000948- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
949 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +0000950 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +0000951
Georg Brandlfee0f442010-05-22 21:26:21 +0000952- Comparisons using one of <, <=, >, >= between a complex instance and a
953 Fractions instance now raise TypeError instead of returning True/False. This
954 makes Fraction <=> complex comparisons consistent with int <=> complex, float
955 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +0000956

965
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000966- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +0000967 didn't support chflags() (for example ZFS under FreeBSD). The error is now
968 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000969
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000970- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
971 deprecated.
972
Georg Brandlfee0f442010-05-22 21:26:21 +0000973- Issue #7860: platform.uname now reports the correct 'machine' type when Python
974 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +0000975

Victor Stinner75227342010-03-12 14:30:26 +00001009
Vinay Sajipecfa08f2010-03-12 09:16:10 +00001010- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001011 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1012 log file to compute the next rollover time. If the log file does not exist,
1013 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00001014
Georg Brandlba83f822010-03-14 09:50:54 +00001015- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Georg Brandlba83f822010-03-14 09:50:54 +00001023- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
1024 a base64 transfer-encoded payload *after* decoding it; it no longer does.
1025 This is a behavior change, so email's minor version number is now bumped, to
1026 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001054- Issue #8300: When passing a non-integer argument to struct.pack with any
1055 integer format code, struct.pack first attempts to convert the non-integer
1056 using its __index__ method. If that method is non-existent or raises
1057 TypeError it goes on to try the __int__ method, as described below.
1058
Georg Brandlba83f822010-03-14 09:50:54 +00001059- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1060 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1061 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001062 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1063 inconsistent: __int__ was used for some integer codes but not for others, and
1064 the set of integer codes for which it was used differed between native packing
1065 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00001369 file position when calling `truncate()`. It would previously change the file
1370 position to the given argument, which goes against the tradition of

1374 class used to represent files stored inside an archive. The new
1375 implementation is significantly faster and can be wrapped in a

1377 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

1390 encoded string for them. This ensures that the upload and register commands
1391 send the correct values to PyPI without any error.

1466-----------------
1467
Georg Brandlba83f822010-03-14 09:50:54 +00001468- The ``__complex__()`` method is now looked up on the class of instances to
1469 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001471- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,

1473
Mark Dickinson1b34d252010-01-01 17:27:30 +00001474- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001475 DeprecationWarning when passed a float argument where an integer was expected.
1476 These functions and methods now raise TypeError instead. The majority of the
1477 effects of this change are in the extension modules, but some core functions
1478 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1479 and many unicode/str methods.

1493 of integers: the result of a/b is now correctly rounded for ints a and b (at
1494 least on IEEE 754 platforms), and in particular does not depend on the
1495 internal representation of a long.

1503
Georg Brandlba83f822010-03-14 09:50:54 +00001504 These executables now work properly with the arch(1) command: ``arch -ppc
1505 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00001662- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1663 decimal string that's guaranteed to round back to x under correct rounding
1664 (with round-half-to-even rounding mode). Previously it gave a string based on
1665 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1666 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1667 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001668
Georg Brandlba83f822010-03-14 09:50:54 +00001669- Issue #7117: On almost all platforms: float-to-string and string-to-float
1670 conversions within Python are now correctly rounded. Places these conversions
1671 occur include: str for floats and complex numbers; the float and complex
1672 constructors; old-style and new-style numeric formatting; serialization and
1673 deserialization of floats and complex numbers using marshal, pickle and json;
1674 parsing of float and imaginary literals in Python code; Decimal-to-float
1675 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001676
Georg Brandlba83f822010-03-14 09:50:54 +00001677 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1678 providing correctly-rounded strtod and dtoa C functions. This code is
1679 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1680 the C compiler. There may be a small number of platforms on which correct
1681 operation of this code cannot be guaranteed, so the code is not used: notably,
1682 this applies to platforms where the C double format is not IEEE 754 binary64,
1683 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1684 and Python's configure script is unable to determine how to change the FPU
1685 precision. On these platforms conversions use the platform strtod and dtoa,
1686 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001688- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1689 uses the correctly-rounded string <-> float conversions described above (when
1690 available), and so produces correctly rounded results that will display nicely
1691 under the float repr. There are two related small changes: (1) round now
1692 accepts any class with an ``__index__()`` method for its second argument (but
1693 no longer accepts floats for the second argument), and (2) an excessively
1694 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1695 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001838 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1839 (2) parsing of strings representing infinities and nans was locale aware; and
1840 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001842- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1843 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1844 but with at least one decimal point and with a default precision
1845 of 12. Previously, the behavior the same but with a default precision of 6.
1846 This more closely matches ``str()``, and reduces surprises when adding
1847 alignment flags to the empty presentation type. This also affects the new
1848 complex.__format__ in the same way.
1849

Georg Brandlba83f822010-03-14 09:50:54 +00002031- Issue #4445: Replace ``sizeof(PyStringObject)`` with
2032 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2033 instances. On a typical machine this saves 3 bytes of memory (on average) per

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002036- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

2045
Georg Brandlba83f822010-03-14 09:50:54 +00002046- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2047 file objects with closefd=False. The file descriptor is still kept open but
2048 the file object behaves like a closed file. The ``FileIO`` object also got a
2049 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00002072- On windows, ``os.chdir()`` given unicode was not working if

2074 this code path is really executed because I cannot move to such directory on

Georg Brandlba83f822010-03-14 09:50:54 +00002077- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2078 element is temporarily replaced with an equivalent frozenset. But the
2079 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00002100- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2101 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2102 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2103 of using the replace error handler in PyUnicode_DecodeUTF8().
2104
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002105- Issue #3739: The unicode-internal encoder now reports the number of characters

2107
Georg Brandlba83f822010-03-14 09:50:54 +00002108- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

2110 gives improved memory leak detection when running under Valgrind, while taking
2111 advantage of pymalloc at other times.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003476- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3477
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003478- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3479 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3480 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3481 ``printf`` function, whereas PyString_FromFormat has an independent
3482 implementation and uses "%zd" on all platforms for size_t values.
3483 This makes a difference on win64, where ``printf`` needs "%Id" to display
3484 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00003486- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3490 object; previously an int would be returned for small values. the __long__
3491 method is allowed to return either an int or a long, but the behaviour of
3492 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003494- Issue #3751: str.rpartition would perform a left-partition when called with

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003501 was correctly parsed but parsing of subsequent arguments failed.
3502
Vinay Sajip35e3b032008-09-01 14:33:59 +00003503- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003504 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3505 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3506 when given a tuple of classes as second argument, were looking up
3507 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3508 type object.

3653-----------------
3654
Guido van Rossumf8402962008-08-20 15:01:50 +00003655- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3656 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3657 extensions do not automatically benefit from the class attribute
3658 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3659 to their tp_flags field if they care. This is a backwards
3660 compatibility feature; in 3.0, all types will use the cache by
3661 default.
3662
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003663- Keyword arguments can now follow starred arguments. (``f(a, *args,
3664 keyword=23)`` is now valid syntax.)
3665
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003666- ctypes function pointers that are COM methods have a boolean True
3667 value again.

3678
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003679- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3680 (64bit Unix, for example), unichr() would truncate its argument and return
3681 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Neal Norwitze7d8be82008-07-31 17:17:14 +00003683- Apply security patches from Apple.
3684
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003685- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

Antoine Pitrou92f82162008-07-25 22:22:08 +00003688- Issue #1819: function calls with several named parameters are now on

3690
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003691- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3692 the python debugger steps into a class statement: the free variables (local

Gregory P. Smith0470bab2008-07-22 04:46:32 +00003695- Issue #2620: Overflow checking when allocating or reallocating memory
3696 was not always being done properly in some python types and extension
3697 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3698 all been updated to perform better checks and places in the code that
3699 would previously leak memory on the error path when such an allocation
3700 failed have been fixed.

3708 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3709
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003710- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3711 version reported by these tools does not necessarily follow the python
3712 version numbering scheme, so the module is less strict when parsing it.
3713
Nick Coghlanf70385a2008-08-18 12:42:46 +00003714- Issue #2235: Added Py3k warnings for types which will become unhashable
3715 under the stricter __hash__ inheritance rules in 3.0. Several types
3716 which did not meet the rules for hash invariants and were already
3717 unhashable in 3.0 have now been explicitly flagged as unhashable in
3718 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3719 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3720
Brett Cannon88f801d2008-08-18 00:46:22 +00003721- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

3753 since mimetools itself is deprecated. Because modules are cached, all
3754 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3755

3765 a MemoryError rather than silently stop the iteration.
3766
Guido van Rossum59ce9012008-08-09 14:55:34 +00003767- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3768 to _sre.compile() will now be rejected. This should not affect anybody
3769 since the re.compile() function never generates invalid re-bytecode.
3770
Skip Montanaroa032bf42008-08-08 22:52:51 +00003771- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3772 upon first access it can be automatically initialized from the csv file if
3773 it wasn't initialized during instantiation.
3774
Brett Cannon3aa2a492008-08-06 22:28:09 +00003775- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3776 the reload() built-in has been removed.
3777
Brett Cannon7e30b672008-08-04 21:52:25 +00003778- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003779 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3787 raised an AttributeError.
3788

Antoine Pitroude781a42008-08-09 12:43:23 +00003790 asking for a specific length. This problem only affected files opened
3791 using the new "io" module, not the built-in open() function.

3817 file name rather than a ZipInfo instance, so files are extracted with
3818 mode 0600 rather than 000 under Unix.
3819
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003820- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3821 argument in python 2.5, this broke code that subclassed Popen to include its

3833 interaction with the tp_hash slot (added in 2.6b2) are now documented
3834
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003835- Issue #643841: The language reference now provides more detailed
3836 coverage of the lookup process for special methods. The disclaimers
3837 regarding lack of coverage of new-style classes have also been
3838 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003846Core and Builtins
3847-----------------
3848
Georg Brandl3e483f62008-07-16 22:57:41 +00003849- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3850 its methods now allow for items objects that can be converted to
3851 an integer using operator.index().
3852
Mark Dickinson64b7e502008-07-16 09:40:03 +00003853- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3854 produced a ValueError instead of giving the correct float.
3855
Eric Smitha5fa5a22008-07-16 00:11:49 +00003856- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3857 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3858
Mark Dickinson7103aa42008-07-15 19:08:33 +00003859- Issue #3008: the float type has a new instance method 'float.hex'
3860 and a new class method 'float.fromhex' to convert floating-point
3861 numbers to and from hexadecimal strings, respectively.
3862
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003863- Issue #2235: __hash__ is once again inherited by default. To allow
3864 collections.Hashable to remain meaningful in the presence of the
3865 default hash implementation (object.__hash__), it is now possible
3866 to explicit block inheritance of hash by setting __hash__=None at
3867 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3868 level.
3869
Nick Coghlanb028f502008-07-13 14:52:36 +00003870- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3871 the parent module cannot be found while performing an absolute import.
3872 This means that an incorrectly defined __package__ attribute will
3873 now only prevent relative imports in that module rather than causing
3874 all imports from that module to fail.
3875
Nick Coghlan14ff9942008-07-08 14:21:42 +00003876- Issue #2517: Allow unicode messages in Exceptions again by correctly
3877 bypassing the instance dictionary when looking up __unicode__ on
3878 new-style classes.
3879
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003880- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3881 set to a custom object whose write() method happens to install
3882 another file in sys.stdout.
3883
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003884- Issue #3088: Corrected a race condition in classes derived from
3885 threading.local: the first member set by a thread could be saved in
3886 another thread's dictionary.
3887
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003888- Issue #3004: Minor change to slice.indices(): the start and stop
3889 arguments are now treated identically, making the behaviour easier
3890 to describe and understand. For example, slice(None, -10,
3891 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3892 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3893 10, -1).
3894
Georg Brandl278fc502008-07-19 12:46:12 +00003895- Issue #3219: Calling a function with repeated keyword arguments,
3896 f(a=2, a=23), would not cause a syntax error. This was a regression
3897 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003898
Georg Brandl278fc502008-07-19 12:46:12 +00003899- Issue #2862: Make int and float freelist management consistent with
3900 other freelists. Changes their CompactFreeList apis into
3901 ClearFreeList apis and calls them via gc.collect().

3907 api functions without holding the GIL, which could lead to a fatal
3908 error when they failed.
3909
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003910- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

3919 ForkingPickler.register() to resolve conflict with ctypes.
3920
Vinay Sajip51e65192008-07-18 09:01:10 +00003921- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00003923- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3924 a valid dlerror() message.
3925
Thomas Heller2bad6572008-07-15 17:19:50 +00003926- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3927 incomplete structure was created.
3928

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003933- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003934
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003935- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3936 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003937 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003938 content-length. The problem had been corrected in the 2.4 branch, but never
3939 merged into trunk.
3940

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003954- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

3956
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003957- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl5cc774e2008-06-11 20:28:06 +00004347 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004348
4349 This is controlled by the configure argument ``--with-universal-archs``:
4350
4351 - ``--with-universal-archs=all``: install 4-way universal
4352
4353 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4354
4355 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4356
4357 This option should be used in combination with ``--enable-universalsdk=``.
4358
4359 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 +00004409- Issue #1631171: Re-implement the 'warnings' module in C (the
4410 original Python code has been kept as backup). This will allow for
4411 using the 'warning's machinery in such places as the parser where
4412 use of pure Python code is not possible. Both the ``showarning()``
4413 and ``formatwarning()`` gain an optional 'line' argument which is
4414 not called by default for backwards-compatibility reasons. Setting
4415 ``warnings.showwarning()`` to an implementation that lacks support
4416 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004479- Issue #2550: The approach used by client/server code for obtaining
4480 ports to listen on in network-oriented tests has been refined in an
4481 effort to facilitate running multiple instances of the entire
4482 regression test suite in parallel without issue.
4483 test_support.bind_port() has been fixed such that it will always
4484 return a unique port -- which wasn't always the case with the
4485 previous implementation, especially if socket options had been set
4486 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4487 new implementation of bind_port() will actually raise an exception
4488 if it is passed an AF_INET/SOCK_STREAM socket with either the
4489 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4490 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4491 the socket it's been passed. This currently only applies to
4492 Windows. This option prevents any other sockets from binding to the
4493 host/port we've bound to, thus removing the possibility of the
4494 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4495 when a second SOCK_STREAM socket binds and accepts to a host/port
4496 that's already been bound by another socket. The optional preferred
4497 port parameter to bind_port() has been removed. Under no
4498 circumstances should tests be hard coding ports!
4499
4500 test_support.find_unused_port() has also been introduced, which will
4501 pass a temporary socket object to bind_port() in order to obtain an
4502 unused port. The temporary socket object is then closed and
4503 deleted, and the port is returned. This method should only be used
4504 for obtaining an unused port in order to pass to an external program
4505 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4506 a parameter to a server-oriented class that doesn't give you direct
4507 access to the underlying socket used.
4508
4509 Finally, test_support.HOST has been introduced, which should be used
4510 for the host argument of any relevant socket calls (i.e. bind and
4511 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004512
4513 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004514 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004515 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4516 test_asynchat and test_socket_ssl.
4517
Georg Brandl3ee81df2008-05-17 18:14:43 +00004518 It is now possible for multiple instances of the regression test

Fred Drakea8ee94b2008-03-01 02:45:07 +00004788- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004789 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004790
Georg Brandlad61bc82008-02-23 15:11:18 +00004791- Issue #2067: file.__exit__() now calls subclasses' close() method.
4792
4793- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004794
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004795- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00004796 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00004797
Eric Smitha73fbe72008-02-23 03:09:44 +00004798- Added the future_builtins module, which contains hex() and oct().
4799 These are the PEP 3127 version of these functions, designed to be
4800 compatible with the hex() and oct() builtins from Python 3.0. They
4801 differ slightly in their output formats from the existing, unchanged
4802 Python 2.6 builtins. The expected usage of the future_builtins
4803 module is:
4804 from future_builtins import hex, oct
4805
Eric Smith7ef40bf2008-02-20 23:34:22 +00004806- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4807 exponents for exponents with absolute value < 100. Follows C99
4808 standard. This is a change on Windows, which would use 3 digits.
4809 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4810 so that any alterations it does to the resulting string will be
4811 available in stringlib/formatter.h (for float.__format__).
4812
Eric Smith5a3c1352008-02-19 13:21:56 +00004813- Implemented PEP 3101, Advanced String Formatting. This adds a new
4814 builtin format(); a format() method for str and unicode; a
4815 __format__() method to object, str, unicode, int, long, float, and
4816 datetime; the class string.Formatter; and the C API
4817 PyObject_Format().
4818
Georg Brandl3ee81df2008-05-17 18:14:43 +00004819- Fixed several potential crashes, all caused by specially crafted
4820 __del__ methods exploiting objects in temporarily inconsistent
4821 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004822
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004823- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004824 prevent a possible crash: an Abstract Base Class would try to access
4825 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004826
Georg Brandl3ee81df2008-05-17 18:14:43 +00004827- Fixed repr() and str() of complex numbers with infinity or nan as
4828 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004829
Georg Brandl3ee81df2008-05-17 18:14:43 +00004830- Clear all free lists during a gc.collect() of the highest generation
4831 in order to allow pymalloc to free more arenas. Python may give back
4832 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004833
Georg Brandl3ee81df2008-05-17 18:14:43 +00004834- Issue #2045: Fix an infinite recursion triggered when printing a
4835 subclass of collections.defaultdict, if its default_factory is set
4836 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004837
Christian Heimesf75dbef2008-02-08 00:11:31 +00004838- Fixed a minor memory leak in dictobject.c. The content of the free
4839 list was not freed on interpreter shutdown.
4840
Georg Brandl21e99f42010-03-07 15:23:59 +00004841- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004842 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004843
Georg Brandl3ee81df2008-05-17 18:14:43 +00004844- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4845 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004846 to compact the internal free lists of pre-allocted ints and floats.
4847
Georg Brandl3ee81df2008-05-17 18:14:43 +00004848- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4849 calls. Python expected the return type int but the fork familie
4850 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004851
Georg Brandl3ee81df2008-05-17 18:14:43 +00004852- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4853 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004854
Georg Brandl3ee81df2008-05-17 18:14:43 +00004855- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4856 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004857
Georg Brandl3ee81df2008-05-17 18:14:43 +00004858- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4859 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00004861- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4862 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004863
Georg Brandl3ee81df2008-05-17 18:14:43 +00004864- Patch #1473257: generator objects gain a gi_code attribute. This is
4865 the same object as the func_code attribute of the function that
4866 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004867
Georg Brandl3ee81df2008-05-17 18:14:43 +00004868- Issue #1920: "while 0" statements were completely removed by the
4869 compiler, even in the presence of an "else" clause, which is
4870 supposed to be run when the condition is false. Now the compiler
4871 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004872
Guido van Rossumeead05f2008-01-24 18:21:02 +00004873- A few crashers fixed: weakref_in_del.py (issue #1377858);
4874 loosing_dict_ref.py (issue #1303614, test67.py);
4875 borrowed_ref_[34].py (not in tracker).
4876
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004877- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004878 suppressed while an extension is loaded by calling SetErrorMode in
4879 dynload_win.c. The error is still reported properly.
4880
Georg Brandl3ee81df2008-05-17 18:14:43 +00004881- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004882 several extension methods and modules do not work without unicode
4883 support.
4884
Georg Brandl26543b12008-01-21 18:36:51 +00004885- Issue #1882: when compiling code from a string, encoding cookies in the
4886 second line of code were not always recognized correctly.
4887
Georg Brandl14404b62008-01-19 19:27:05 +00004888- Issue #1679: "0x" was taken as a valid integer literal.
4889
Georg Brandl6caad7d2008-01-26 14:19:22 +00004890- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004891 added.
4892
Christian Heimesc94e2b52008-01-14 04:13:37 +00004893- sys.float_info / PyFloat_GetInfo: The floating point information
4894 object was converted from a dict to a specialized structseq object.
4895
Georg Brandl3ee81df2008-05-17 18:14:43 +00004896- Patch #1816: Added sys.flags structseq. It exposes the status of
4897 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004898
Georg Brandl3ee81df2008-05-17 18:14:43 +00004899- Objects/structseq.c: Implemented new structseq representation. The
4900 patch makes structseqs (e.g. the return value of os.stat) more
4901 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004902
Georg Brandl3ee81df2008-05-17 18:14:43 +00004903- Patch #1700288: added a type attribute cache that caches method
4904 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004905
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004906- Bug #1776: __import__() no longer accepts filenames on any platform.
4907 The first parameter to __import__() must be a valid module name.

4910
Georg Brandl3ee81df2008-05-17 18:14:43 +00004911- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4912 envvar and sys.dont_write_bytecode attribute. All these can be set
4913 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004914
Georg Brandl3ee81df2008-05-17 18:14:43 +00004915- Improve some exception messages when Windows fails to load an
4916 extension module. Now we get for example '%1 is not a valid Win32
4917 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004918
Georg Brandl3ee81df2008-05-17 18:14:43 +00004919- Bug #1481296: Fixed long(float('nan')) != 0L.

4922 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004923
Christian Heimes0a8143f2007-12-18 23:22:54 +00004924- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004925 and INF. float("nan"), float("inf") and float("-inf") now work on
4926 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004927
Georg Brandl3ee81df2008-05-17 18:14:43 +00004928- Compiler now generates simpler and faster code for dictionary
4929 literals. The oparg for BUILD_MAP now indicates an estimated
4930 dictionary size. There is a new opcode, STORE_MAP, for adding
4931 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004932

4961 file can now be directly executed by passing their name to the
4962 interpreter. The directory/zipfile is automatically inserted as the
4963 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004964
Georg Brandl3ee81df2008-05-17 18:14:43 +00004965- Issue #1265: Fix a problem with sys.settrace, if the tracing
4966 function uses a generator expression when at the same time the
4967 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004968
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004969- sets and frozensets now have an isdisjoint() method.
4970
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004971- optimize the performance of builtin.sum().

4974
Georg Brandl21e99f42010-03-07 15:23:59 +00004975- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004976 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4977 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004978
Georg Brandl3ee81df2008-05-17 18:14:43 +00004979- Issue #1686386: Tuple's tp_repr did not take into account the
4980 possibility of having a self-referential tuple, which is possible
4981 from C code. Nor did object's tp_str consider that a type's tp_str
4982 could do something that could lead to an inifinite recursion.
4983 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4984 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004985
Georg Brandl3ee81df2008-05-17 18:14:43 +00004986- Issue #1164: It was possible to trigger deadlock when using the
4987 'print' statement to write to a file since the GIL was not released
4988 as needed. Now PyObject_Print() does the right thing along with
4989 various tp_print implementations of the built-in types and those in
4990 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004991
Georg Brandl3ee81df2008-05-17 18:14:43 +00004992- Issue #1147: Exceptions were directly allowing string exceptions in
4993 their throw() method even though string exceptions no longer
4994 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004995

Brett Cannon1e534b52007-09-07 04:18:30 +00004999- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005000 PyObject_Call() never calling back out to Python code to trigger
5001 recursion depth updates/checks. Required the creation of a static
5002 RuntimeError instance in case normalizing an exception put the
5003 recursion check value past its limit. Fixes crashers
5004 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005005

Georg Brandl3ee81df2008-05-17 18:14:43 +00005020 __*__ attributes. (Some already existed, e.g., __doc__ and
5021 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005022
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005023- Add -3 option to the interpreter to warn about features that are
5024 deprecated and will be changed/removed in Python 3.0.
5025
Georg Brandl2134e752007-05-21 20:34:16 +00005026- Patch #1686487: you can now pass any mapping after '**' in function
5027 calls.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005030 "except E as target:". This is to provide forwards compatibility
5031 with Python 3.0.

Guido van Rossum143b5642007-03-23 04:58:42 +00005052- Bug #1683368: The object.__init__() and object.__new__() methods are
5053 now stricter in rejecting excess arguments. The only time when
5054 either allows excess arguments is when it is not overridden and the
5055 other one is. For backwards compatibility, when both are
5056 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005057 warning later). Also, type.__init__() insists on the same signature
5058 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005060- Patch #1675423: PyComplex_AsCComplex() now tries to convert an

5062 to the __float__() method. Therefore, the functions in the cmath
5063 module now can operate on objects that define a __complex__()
5064 method.

5084
Georg Brandl871f1bc2007-03-12 13:17:36 +00005085- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005086 its argument, if it exists. If not, it will work like before. This
5087 allows customizing the output of dir() in the presence of a

5098 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00005100- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005101 makes the filenames the warning module prints much more sensible
5102 when a PYTHONSTARTUP file is used.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005653 AttributeError instead of an IOError when the server's response

5745 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00006030- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6031 with RFC 3207 and forgets any knowledge obtained from the server not
6032 obtained from the TLS negotiation itself. Patch contributed by Bill
6033 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006034
Georg Brandl3ee81df2008-05-17 18:14:43 +00006035- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006036 that the SMTP.starttls() caller no longer needs to call ehlo()
6037 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006038 does not claim to support starttls. Adds the
6039 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

6120 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6121 silently miscode subclasses of those types. Now, it raises a
6122 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006123

Georg Brandl3ee81df2008-05-17 18:14:43 +00006138 time so that opening a database previously created with the DB_DUP
6139 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6140 opens. Specifically: dictionary assignment to a DB object will
6141 replace all values for a given key when the database allows
6142 duplicate values. DB users should use DB.put(k, v) when they want
6143 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006144

6150 characters with ASCII value less than 32. Also, it correctly quotes
6151 dots only if they occur on a single line, as opposed to the previous
6152 behavior of quoting dots if they are the second character of any
6153 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006154

6496 ``PyFloat_GetInfo()`` to the float API.
6497
Georg Brandl3ee81df2008-05-17 18:14:43 +00006498- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6499 of w# format code incorrectly truncated the length to an int, even
6500 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6501 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006503- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
6504 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006506- PEP 3123: Provide forward compatibility with Python 3.0, while
6507 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
6508 and PyVarObject_HEAD_INIT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006510- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
6511 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006512
6513- Patch #1733960: Allow T_LONGLONG to accept ints.
6514
6515- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
6516
Christian Heimes000a0742008-01-03 22:16:32 +00006517- Added a new API function ``PyImport_ImportModuleNoBlock``.

6520
6521- Fix some leftovers from the conversion from int to Py_ssize_t
6522 (relevant to strings and sequences of more than 2**31 items).
6523
6524- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6525 outside of pystate.c and should not be necessary.
6526
Georg Brandl3ee81df2008-05-17 18:14:43 +00006527- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do

Georg Brandl3ee81df2008-05-17 18:14:43 +00006531- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6532 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006533
Georg Brandl3ee81df2008-05-17 18:14:43 +00006534- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00006541- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
6542 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6543 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6544 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006559- Removed the macfs module. It had been deprecated since Python 2.5.
6560 This lead to the deprecation of macostools.touched() as it relied
6561 solely on macfs and was a no-op under OS X.
