12Core and Builtins
13-----------------
14
Mark Dickinsoncb61e5d2010-09-26 10:37:12 +000015- Issue #9869: Make long() and PyNumber_Long return something of type
16 long for a class whose __long__ method returns a plain int. This
17 fixes an interpreter crash when initializing an instance of a long
18 subclass from an object whose __long__ method returns a plain int.
19
Antoine Pitrou0a7b65b2010-09-08 12:40:49 +000020- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
21 thread-local storage key.
22
Victor Stinnercaafd772010-09-08 10:51:01 +000023- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
24 encoding and errors attributes instead of using utf-8 in strict mode, to get
25 the same behaviour than the print statement.
26
Antoine Pitrou9cf85f12010-09-01 21:17:34 +000027- Issue #9737: Fix a crash when trying to delete a slice or an item from
28 a memoryview object.
29
Martin v. Löwis6086b0d2010-08-19 09:09:04 +000030- Restore GIL in nis_cat in case of error.
31
Benjamin Peterson6f3d6a92010-08-25 23:17:42 +000032- Issue #9688: __basicsize__ and __itemsize__ must be accessed as Py_ssize_t.
33
Florent Xicluna172e15f2010-08-09 20:02:00 +000034- Issue #8530: Prevent stringlib fastsearch from reading beyond the front
35 of an array.
36
Raymond Hettinger3ad323e2010-08-06 10:18:56 +000037- Issue #83755: Implicit set-to-frozenset conversion was not thread-safe.
38
Mark Dickinsonaad57bd2010-08-01 10:45:15 +000039- Issue #9416: Fix some issues with complex formatting where the
40 output with no type specifier failed to match the str output:
41
42 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
43 - format(complex(0.0, 2.0), '-') included a sign and parentheses.
44
Antoine Pitrou32669782010-07-11 12:14:05 +000045- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
46 compiler.

49-------
50
Antoine Pitrou66b5df62010-09-27 18:16:46 +000051- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
52 received. Now sendall() properly calls signal handlers if necessary,
53 and retries sending if these returned successfully, including on sockets
54 with a timeout.
55
Vinay Sajip3eac5912010-09-25 17:48:25 +000056- Issue #9947: logging: Fixed locking bug in stopListening.
57
Vinay Sajip546885e2010-09-25 17:42:36 +000058- Issue #9945: logging: Fixed locking bugs in addHandler/removeHandler.
59
Alexander Belopolsky517185e2010-09-24 18:14:18 +000060- Issue #9936: Fixed executable lines' search in the trace module.
61
Antoine Pitrou2c7d6852010-09-23 19:55:24 +000062- Issue #9928: Properly initialize the types exported by the bz2 module.
63
Antoine Pitrou6391b342010-09-14 18:48:19 +000064- Issue #9854: The default read() implementation in io.RawIOBase now
65 handles non-blocking readinto() returning None correctly.
66
Antoine Pitrouf7f390a2010-09-14 14:37:18 +000067- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
68 SSLSocket.sendto() to match the corresponding socket methods. Also,
69 fix various SSLSocket methods to raise socket.error rather than an
70 unhelpful TypeError when called on an unconnected socket. Original patch
71 by Andrew Bennetts.
72
Raymond Hettinger74f869e2010-09-13 22:14:36 +000073- Issue #9826: OrderedDict.__repr__ can now handle self-referential
74 values: d['x'] = d.
75
Victor Stinner8fc843b2010-09-17 23:35:50 +000076- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X.
Victor Stinner46287f52010-09-13 20:31:34 +000077
Antoine Pitroue4195e82010-09-12 14:56:27 +000078- Issue #9837: The read() method of ZipExtFile objects (as returned by
79 ZipFile.open()) could return more bytes than requested.
80
Raymond Hettinger20397532010-09-12 02:11:45 +000081- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
82 This prevents user-created self-referencing ordered dictionaries from
83 becoming permanently uncollectable GC garbage. The downside is that
84 removing __del__ means that the internal doubly-linked list has to wait for
85 GC collection rather than freeing memory immediately when the refcnt drops
86 to zero.
87
Raymond Hettingerffd2a422010-09-10 10:47:22 +000088- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
89 different internal state for small values of n. Fixed by salting the
90 value.
91
Antoine Pitrouc818ed42010-09-07 21:40:25 +000092- Issue #9792: In case of connection failure, socket.create_connection()
93 would swallow the exception and raise a new one, making it impossible
94 to fetch the original errno, or to filter timeout errors. Now the
95 original error is re-raised.
96
Antoine Pitrouf4f61712010-09-07 16:34:47 +000097- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
98 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
99 be updated back after the system call. Original patch by Brian Brazil.
100
Antoine Pitroudca9de92010-09-04 17:52:26 +0000101- Issue #1100562: Fix deep-copying of objects derived from the list and
102 dict types. Patch by Michele Orrù and Björn Lindqvist.
103
Fred Drakea1e627d2010-09-03 03:55:50 +0000104- Issue #7005: Fixed output of None values for RawConfigParser.write and
105 ConfigParser.write.
106
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000107- Issue #808164: Fixed socket.close to avoid references to globals, to
108 avoid issues when socket.close is called from a __del__ method.
109
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +0000110- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
111 falling into recursion.
112
R. David Murray7c4bf552010-08-25 01:45:57 +0000113- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
114 character years even if the message contains RFC822 two character years.
115
Daniel Stutzbach91287322010-08-24 21:09:30 +0000116- Issue #8750: Fixed MutableSet's methods to correctly handle
117 reflexive operations, namely x -= x and x ^= x.
118
Victor Stinnercaafd772010-09-08 10:51:01 +0000119- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing
Giampaolo Rodolà8664d742010-08-23 22:48:51 +0000120 error handling when accepting a new connection.
121
Giampaolo Rodolà63308d72010-08-23 21:58:47 +0000122- Issue #658749: asyncore's connect() method now correctly interprets winsock
123 errors.
124
Vinay Sajip1ddd51f2010-08-23 17:50:30 +0000125- Issue #9501: Fixed logging regressions in cleanup code.
126

128 module now correctly return a set. (Patch by Eli Bendersky.)
129
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000130- Issue #9617: Signals received during a low-level write operation aren't
131 ignored by the buffered IO layer anymore.
132
Benjamin Peterson52c36052010-08-21 03:03:22 +0000133- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
134 are not held onto after they are deleted elsewhere.
135
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000136- Issue #9626: the view methods for collections.OrderedDict() were returning
137 the unordered versions inherited from dict. Those methods are now
138 overridden to provide ordered views.
139
Éric Araujo0389ae62010-08-14 03:07:46 +0000140- Issue #8688: MANIFEST files created by distutils now include a magic
141 comment indicating they are generated. Manually maintained MANIFESTs
142 without this marker will not be overwritten or removed.
143
Antoine Pitroue1436d12010-08-12 15:25:51 +0000144- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
145 and a BadZipfile error is raised if it doesn't match (as used to be the
146 case in Python 2.5 and earlier).
147
Antoine Pitroucb4f47c2010-08-11 13:40:17 +0000148- Issue #9550: a BufferedReader could issue an additional read when the
149 original read request had been satisfied, which could block indefinitely
150 when the underlying raw IO channel was e.g. a socket. Report and original
151 patch by Jason V. Miller.
152
Fred Drake0a1fa0e2010-08-10 13:09:54 +0000153- Issue #9551: Don't raise TypeError when setting the value to None for

158
Antoine Pitrou99009162010-08-09 22:51:24 +0000159- Issue #3757: thread-local objects now support cyclic garbage collection.
160 Thread-local objects involved in reference cycles will be deallocated
161 timely by the cyclic GC, even if the underlying thread is still running.
162
Florent Xicluna2f1b1ff2010-08-09 20:46:49 +0000163- Issue #6231: Fix xml.etree.ElementInclude to include the tail of the

519 start byte and the continuation byte(s) are now considered invalid, instead
520 of the number of bytes specified by the start byte.
521 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
522 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
523 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

534 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +0000878- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000879 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
880 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
881 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

Benjamin Peterson5da7e7c2010-03-06 22:44:07 +0000900
901Core and Builtins
902-----------------
903
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000904- Issue #7301: Add environment variable $PYTHONWARNINGS.
905
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000906- Issue #8329: Don't return the same lists from select.select when no fds are
907 changed.
908
Georg Brandlfee0f442010-05-22 21:26:21 +0000909- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000910 on 64-bit machines. The shift count for either left or right shift is
911 permitted to be up to sys.maxsize.
912
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000913- Ensure that tokenization of identifiers is not affected by locale.
914
Georg Brandlfee0f442010-05-22 21:26:21 +0000915- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +0000916
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000917- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
918
Georg Brandlfee0f442010-05-22 21:26:21 +0000919- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
920 with a non-empty format string. This is an effort to future-proof user
921 code. If a derived class does not currently implement __format__ but later
922 adds its own __format__, it would most likely break user code that had
923 supplied a format string. This will be changed to a DeprecationWaring in
924 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000925
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000926- Issue #8268: Old-style classes (not just instances) now support weak

Benjamin Peterson96545892010-03-21 20:21:00 +0000934- Issue #6474: Make error message from passing an inadequate number of keyword
935 arguments to a function correct.
936
Benjamin Peterson0dee9c12010-03-17 20:41:42 +0000937- Issue #8164: Don't allow lambda functions to have a docstring.

950
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000951- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000952 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
953 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000954
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000955- Issue #8310: Allow dis to examine new style classes.
956
Georg Brandlfee0f442010-05-22 21:26:21 +0000957- Issue #8257: The Decimal construct now accepts a float instance directly,
958 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000959
960 >>> Decimal(1.1)
961 Decimal('1.100000000000000088817841970012523233890533447265625')
962
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000963- collections.Counter() now supports a subtract() method.
964
Georg Brandlfee0f442010-05-22 21:26:21 +0000965- The functools module now has a total_ordering() class decorator to simplify
966 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000967
Georg Brandlfee0f442010-05-22 21:26:21 +0000968- The functools module also adds cmp_to_key() as a tool to transition old-style
969 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +0000970
Georg Brandlfee0f442010-05-22 21:26:21 +0000971- Issue #8294: The Fraction constructor now accepts Decimal and float instances
972 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000973
Georg Brandlfee0f442010-05-22 21:26:21 +0000974- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
975 InvalidOperation instead of returning False. (Comparisons involving a quiet
976 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
977 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000978
Georg Brandlfee0f442010-05-22 21:26:21 +0000979- Issue #2531: Comparison operations between floats and Decimal instances now
980 return a result based on the numeric values of the operands; previously they
981 returned an arbitrary result based on the relative ordering of id(float) and
982 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000983
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000984- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000985 argument `-` which tells it to read files to compile from stdin. Each line is
986 read on demand and the named file is compiled immediately. (Original patch by
987 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000988
Georg Brandlfee0f442010-05-22 21:26:21 +0000989- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
990 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +0000992- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
993 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +0000994 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +0000995
Georg Brandlfee0f442010-05-22 21:26:21 +0000996- Comparisons using one of <, <=, >, >= between a complex instance and a
997 Fractions instance now raise TypeError instead of returning True/False. This
998 makes Fraction <=> complex comparisons consistent with int <=> complex, float
999 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001000

1009
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001010- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001011 didn't support chflags() (for example ZFS under FreeBSD). The error is now
1012 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001013
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00001014- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
1015 deprecated.
1016
Georg Brandlfee0f442010-05-22 21:26:21 +00001017- Issue #7860: platform.uname now reports the correct 'machine' type when Python

Vinay Sajipecfa08f2010-03-12 09:16:10 +00001054- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001055 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1056 log file to compute the next rollover time. If the log file does not exist,
1057 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00001058
Georg Brandlba83f822010-03-14 09:50:54 +00001059- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Georg Brandlba83f822010-03-14 09:50:54 +00001067- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
1068 a base64 transfer-encoded payload *after* decoding it; it no longer does.
1069 This is a behavior change, so email's minor version number is now bumped, to
1070 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001098- Issue #8300: When passing a non-integer argument to struct.pack with any
1099 integer format code, struct.pack first attempts to convert the non-integer
1100 using its __index__ method. If that method is non-existent or raises
1101 TypeError it goes on to try the __int__ method, as described below.
1102
Georg Brandlba83f822010-03-14 09:50:54 +00001103- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1104 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1105 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001106 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1107 inconsistent: __int__ was used for some integer codes but not for others, and

Georg Brandlba83f822010-03-14 09:50:54 +00001512- The ``__complex__()`` method is now looked up on the class of instances to
1513 make it consistent with other special methods.

1517
Mark Dickinson1b34d252010-01-01 17:27:30 +00001518- Issue #5080: A number of functions and methods previously produced a

1520 These functions and methods now raise TypeError instead. The majority of the
1521 effects of this change are in the extension modules, but some core functions
1522 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1523 and many unicode/str methods.

1537 of integers: the result of a/b is now correctly rounded for ints a and b (at
1538 least on IEEE 754 platforms), and in particular does not depend on the
1539 internal representation of a long.

1547
Georg Brandlba83f822010-03-14 09:50:54 +00001548 These executables now work properly with the arch(1) command: ``arch -ppc
1549 python`` will start a universal binary version of python in PPC mode (unlike

1690 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001691
Georg Brandlba83f822010-03-14 09:50:54 +00001692- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1693 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001694
Georg Brandlba83f822010-03-14 09:50:54 +00001695- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1696 1e-100 used to raise OverflowError, but now gives the requested 120
1697 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001705
Georg Brandlba83f822010-03-14 09:50:54 +00001706- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1707 decimal string that's guaranteed to round back to x under correct rounding
1708 (with round-half-to-even rounding mode). Previously it gave a string based on
1709 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1710 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1711 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001712
Georg Brandlba83f822010-03-14 09:50:54 +00001713- Issue #7117: On almost all platforms: float-to-string and string-to-float
1714 conversions within Python are now correctly rounded. Places these conversions
1715 occur include: str for floats and complex numbers; the float and complex
1716 constructors; old-style and new-style numeric formatting; serialization and
1717 deserialization of floats and complex numbers using marshal, pickle and json;
1718 parsing of float and imaginary literals in Python code; Decimal-to-float
1719 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001720
Georg Brandlba83f822010-03-14 09:50:54 +00001721 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1722 providing correctly-rounded strtod and dtoa C functions. This code is
1723 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1724 the C compiler. There may be a small number of platforms on which correct
1725 operation of this code cannot be guaranteed, so the code is not used: notably,
1726 this applies to platforms where the C double format is not IEEE 754 binary64,
1727 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1728 and Python's configure script is unable to determine how to change the FPU
1729 precision. On these platforms conversions use the platform strtod and dtoa,
1730 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001731
Georg Brandlba83f822010-03-14 09:50:54 +00001732- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1733 uses the correctly-rounded string <-> float conversions described above (when
1734 available), and so produces correctly rounded results that will display nicely
1735 under the float repr. There are two related small changes: (1) round now
1736 accepts any class with an ``__index__()`` method for its second argument (but
1737 no longer accepts floats for the second argument), and (2) an excessively
1738 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1739 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001886- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1887 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1888 but with at least one decimal point and with a default precision
1889 of 12. Previously, the behavior the same but with a default precision of 6.
1890 This more closely matches ``str()``, and reduces surprises when adding
1891 alignment flags to the empty presentation type. This also affects the new
1892 complex.__format__ in the same way.

2089
Georg Brandlba83f822010-03-14 09:50:54 +00002090- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2091 file objects with closefd=False. The file descriptor is still kept open but
2092 the file object behaves like a closed file. The ``FileIO`` object also got a
2093 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002113- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00002116- On windows, ``os.chdir()`` given unicode was not working if
2117 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2118 this code path is really executed because I cannot move to such directory on
2119 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002121- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2122 element is temporarily replaced with an equivalent frozenset. But the
2123 eventual KeyError would always report the empty ``frozenset()`` as the missing
2124 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00002144- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2145 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2146 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2147 of using the replace error handler in PyUnicode_DecodeUTF8().
2148
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002149- Issue #3739: The unicode-internal encoder now reports the number of characters

2151
Georg Brandlba83f822010-03-14 09:50:54 +00002152- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2153 allocator will be automatically disabled when running under Valgrind. This
2154 gives improved memory leak detection when running under Valgrind, while taking
2155 advantage of pymalloc at other times.

3400 the tests if DISPLAY is defined but can't be used.

Antoine Pitrou4698d992009-05-31 14:20:14 +00003402- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
3403 regression tests in parallel, shortening the total runtime.
3404
Georg Brandlba83f822010-03-14 09:50:54 +00003405- Issue #5354: New test support function import_fresh_module() makes it easy to
3406 import both normal and optimised versions of modules. test_heapq and
3407 test_warnings have been adjusted to use it, tests for other modules with both
3408 C and Python implementations in the stdlib can be adjusted to use it over
3409 time.

3418 should cause a test to be skipped are now done using import_module from test
3419 support, which does the conversion.

3521
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003522- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3523 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3524 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3525 ``printf`` function, whereas PyString_FromFormat has an independent
3526 implementation and uses "%zd" on all platforms for size_t values.
3527 This makes a difference on win64, where ``printf`` needs "%Id" to display
3528 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00003530- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3534 object; previously an int would be returned for small values. the __long__
3535 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003545 was correctly parsed but parsing of subsequent arguments failed.
3546
Vinay Sajip35e3b032008-09-01 14:33:59 +00003547- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003548 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3549 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3550 when given a tuple of classes as second argument, were looking up
3551 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3552 type object.
3553

3692================================
3693
Barry Warsaw07a4a382008-08-21 01:15:08 +00003694*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003695
3696Core and Builtins
3697-----------------
3698
Guido van Rossumf8402962008-08-20 15:01:50 +00003699- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3700 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3701 extensions do not automatically benefit from the class attribute
3702 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3703 to their tp_flags field if they care. This is a backwards
3704 compatibility feature; in 3.0, all types will use the cache by
3705 default.
3706
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003707- Keyword arguments can now follow starred arguments. (``f(a, *args,
3708 keyword=23)`` is now valid syntax.)
3709
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003710- ctypes function pointers that are COM methods have a boolean True
3711 value again.
3712
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003713- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3714 by denying s# to parse objects that have a releasebuffer procedure,
3715 and introducing s*.
3716
Georg Brandl1e13ea92008-08-11 09:07:59 +00003717- Issue #3537: Fix an assertion failure when an empty but presized dict
3718 object was stored in the freelist.
3719
Mark Dickinsonb6467572008-08-04 21:30:09 +00003720- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3721 ValueError consistently across platforms.
3722
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003723- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3724 (64bit Unix, for example), unichr() would truncate its argument and return
3725 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3726
Neal Norwitze7d8be82008-07-31 17:17:14 +00003727- Apply security patches from Apple.
3728
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003729- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3730 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3731
Antoine Pitrou92f82162008-07-25 22:22:08 +00003732- Issue #1819: function calls with several named parameters are now on
3733 average 35% faster (as measured by pybench).
3734
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003735- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3736 the python debugger steps into a class statement: the free variables (local
3737 variables defined in an outer scope) would be deleted from the outer scope.
3738
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003739- Issue #2620: Overflow checking when allocating or reallocating memory
3740 was not always being done properly in some python types and extension
3741 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3742 all been updated to perform better checks and places in the code that
3743 would previously leak memory on the error path when such an allocation
3744 failed have been fixed.
3745
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003746Library
3747-------
3748
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003749- Issue #3612: Added some missing basic types in ctypes.wintypes.
3750
Benjamin Petersone977ad42008-08-20 01:42:01 +00003751- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3752 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3753
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003754- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3755 version reported by these tools does not necessarily follow the python
3756 version numbering scheme, so the module is less strict when parsing it.
3757
Nick Coghlanf70385a2008-08-18 12:42:46 +00003758- Issue #2235: Added Py3k warnings for types which will become unhashable
3759 under the stricter __hash__ inheritance rules in 3.0. Several types
3760 which did not meet the rules for hash invariants and were already
3761 unhashable in 3.0 have now been explicitly flagged as unhashable in
3762 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3763 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3764
Brett Cannon88f801d2008-08-18 00:46:22 +00003765- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3766 imported into the module but exposed as part of the module's API.
3767
Brett Cannon7b96f072008-08-18 00:41:11 +00003768- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3769
Brett Cannon46225e72008-08-18 00:36:52 +00003770- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
3771
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003772- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3773
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003774- Issue #3575: Incremental decoder's decode function now takes bytearray
3775 by using 's*' instead of 't#'.
3776
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003777- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003778 fails unicode conversion on 2nd parameter. (windows only)
3779
Georg Brandl222e2082010-08-01 22:27:39 +00003780- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003781 in a redirect.
3782
Brett Cannonabe423e2008-08-16 21:47:07 +00003783- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003784 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003785
Facundo Batistaeb90b782008-08-16 14:44:07 +00003786- Issue #2776: fixed small issue when handling an URL with double slash
3787 after a 302 response in the case of not going through a proxy.
3788
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003789- Issue #2676: in the email package, content-type parsing was hanging on
3790 pathological input because of quadratic or exponential behaviour of a
3791 regular expression.
3792
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003793- Issue #3476: binary buffered reading through the new "io" library is now
3794 thread-safe.
3795
Brett Cannonbf3157b2008-08-14 05:00:03 +00003796- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3797 since mimetools itself is deprecated. Because modules are cached, all
3798 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3799
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003800- Issue #3134: shutil referenced undefined WindowsError symbol.
3801
Robert Schuppenies14646332008-08-10 11:01:53 +00003802- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3803 menu entries were not deleted.
3804
Brett Cannon83e81842008-08-09 23:30:55 +00003805- Copied the implementation of reduce() to _functools.reduce() to have a
3806 version that did not raise a DeprecationWarning under -3.
3807
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003808- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3809 a MemoryError rather than silently stop the iteration.
3810
Guido van Rossum59ce9012008-08-09 14:55:34 +00003811- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3812 to _sre.compile() will now be rejected. This should not affect anybody
3813 since the re.compile() function never generates invalid re-bytecode.
3814
Skip Montanaroa032bf42008-08-08 22:52:51 +00003815- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3816 upon first access it can be automatically initialized from the csv file if
3817 it wasn't initialized during instantiation.
3818
Brett Cannon3aa2a492008-08-06 22:28:09 +00003819- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3820 the reload() built-in has been removed.
3821
Brett Cannon7e30b672008-08-04 21:52:25 +00003822- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003823 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00003824 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
3825 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
3826 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
3827 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
3828 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00003829
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00003830- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
3831 raised an AttributeError.
3832
Benjamin Peterson01a24322008-07-28 23:35:27 +00003833- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003834 asking for a specific length. This problem only affected files opened
3835 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003836
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003837- Issue #3449: Update decimal module to use most recent specification
3838 (v. 1.68) and tests (v. 2.58) from IBM.
3839
Georg Brandl222e2082010-08-01 22:27:39 +00003840- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00003841

3844
Georg Brandlf9efabb2008-07-23 15:16:45 +00003845- Deprecate the "ast" parser function aliases.
3846
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003847- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
3848
3849- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3850 invalid arguments.
3851
3852- Issue #3302: Fix several crashes when calling locale's gettext functions
3853 with None arguments.
3854
3855- Issue #3389: Allow resolving dotted names for handlers in logging
3856 configuration files.
3857

3859
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003860- Issue #3394: zipfile.writestr sets external attributes when passed a
3861 file name rather than a ZipInfo instance, so files are extracted with
3862 mode 0600 rather than 000 under Unix.
3863
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003864- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3865 argument in python 2.5, this broke code that subclassed Popen to include its
3866 own poll method. Fixed my moving _deadstate to an _internal_poll method.
3867
Martin v. Löwis8dbf3642008-08-01 14:10:26 +00003868Build

3874-------------
3875
Nick Coghlan6e8fef02008-08-18 13:14:22 +00003876- Issue #2235: the C API function PyObject_HashNotImplemented and its
3877 interaction with the tp_hash slot (added in 2.6b2) are now documented
3878
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003879- Issue #643841: The language reference now provides more detailed
3880 coverage of the lookup process for special methods. The disclaimers
3881 regarding lack of coverage of new-style classes have also been
3882 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003885What's New in Python 2.6 beta 2?
3886================================
3887
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003888*Release date: 17-Jul-2008*
3889
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003890Core and Builtins
3891-----------------
3892
Georg Brandl3e483f62008-07-16 22:57:41 +00003893- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3894 its methods now allow for items objects that can be converted to
3895 an integer using operator.index().
3896
Mark Dickinson64b7e502008-07-16 09:40:03 +00003897- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3898 produced a ValueError instead of giving the correct float.
3899
Eric Smitha5fa5a22008-07-16 00:11:49 +00003900- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3901 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3902
Mark Dickinson7103aa42008-07-15 19:08:33 +00003903- Issue #3008: the float type has a new instance method 'float.hex'
3904 and a new class method 'float.fromhex' to convert floating-point
3905 numbers to and from hexadecimal strings, respectively.
3906
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003907- Issue #2235: __hash__ is once again inherited by default. To allow
3908 collections.Hashable to remain meaningful in the presence of the
3909 default hash implementation (object.__hash__), it is now possible
3910 to explicit block inheritance of hash by setting __hash__=None at
3911 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3912 level.
3913
Nick Coghlanb028f502008-07-13 14:52:36 +00003914- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3915 the parent module cannot be found while performing an absolute import.
3916 This means that an incorrectly defined __package__ attribute will
3917 now only prevent relative imports in that module rather than causing
3918 all imports from that module to fail.
3919
Nick Coghlan14ff9942008-07-08 14:21:42 +00003920- Issue #2517: Allow unicode messages in Exceptions again by correctly
3921 bypassing the instance dictionary when looking up __unicode__ on
3922 new-style classes.
3923
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003924- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3925 set to a custom object whose write() method happens to install
3926 another file in sys.stdout.
3927
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003928- Issue #3088: Corrected a race condition in classes derived from
3929 threading.local: the first member set by a thread could be saved in
3930 another thread's dictionary.
3931
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003932- Issue #3004: Minor change to slice.indices(): the start and stop
3933 arguments are now treated identically, making the behaviour easier
3934 to describe and understand. For example, slice(None, -10,
3935 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3936 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3937 10, -1).
3938
Georg Brandl278fc502008-07-19 12:46:12 +00003939- Issue #3219: Calling a function with repeated keyword arguments,
3940 f(a=2, a=23), would not cause a syntax error. This was a regression
3941 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003942
Georg Brandl278fc502008-07-19 12:46:12 +00003943- Issue #2862: Make int and float freelist management consistent with
3944 other freelists. Changes their CompactFreeList apis into
3945 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00003946

3949
Thomas Heller57adf222008-08-14 19:10:48 +00003950- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3951 api functions without holding the GIL, which could lead to a fatal
3952 error when they failed.
3953
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003954- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00003962- Issue #3125: Remove copy_reg in multiprocessing and replace it with
3963 ForkingPickler.register() to resolve conflict with ctypes.
3964
Vinay Sajip51e65192008-07-18 09:01:10 +00003965- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

3968 a valid dlerror() message.
3969
Thomas Heller2bad6572008-07-15 17:19:50 +00003970- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3971 incomplete structure was created.
3972

Raymond Hettingerb01713e2008-07-10 14:34:57 +00003975- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
3976

4388
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004389- On MacOS X it is now possible to install the framework in 64-bit
4390 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004391 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004392
4393 This is controlled by the configure argument ``--with-universal-archs``:
4394
4395 - ``--with-universal-archs=all``: install 4-way universal
4396
4397 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4398
4399 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4400
4401 This option should be used in combination with ``--enable-universalsdk=``.
4402
4403 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 +00004439- Issue #2670: Fix a failure in urllib2.build_opener(), when passed
4440 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00004441
Christian Heimese74c8f22008-04-19 02:23:57 +00004442- Added kill, terminate and send_signal(sig) to subprocess.Popen.
4443
Georg Brandl3ee81df2008-05-17 18:14:43 +00004444- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
4445 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00004446
Georg Brandl3ee81df2008-05-17 18:14:43 +00004447- Four new methods were added to the math and cmath modules: acosh,

Georg Brandl3ee81df2008-05-17 18:14:43 +00004453- Issue #1631171: Re-implement the 'warnings' module in C (the
4454 original Python code has been kept as backup). This will allow for
4455 using the 'warning's machinery in such places as the parser where
4456 use of pure Python code is not possible. Both the ``showarning()``
4457 and ``formatwarning()`` gain an optional 'line' argument which is
4458 not called by default for backwards-compatibility reasons. Setting
4459 ``warnings.showwarning()`` to an implementation that lacks support
4460 for the ``line`` argument will raise a DeprecationWarning.

Thomas Hellerbf027c42008-04-24 18:14:19 +00004483 reference to themselves.
4484
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004485- The getpass module has been improved on Unix. It now uses /dev/tty
4486 by default and uses stderr instead of stdout. A GetPassWarning is
4487 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00004488

4499 implementation detail of the public ``types`` module, has been
4500 removed and replaced by pure python code.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004502- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004503 extension modules between 32 and 64 bit platforms. See the distutls
4504 build documentation for more information.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004523- Issue #2550: The approach used by client/server code for obtaining
4524 ports to listen on in network-oriented tests has been refined in an
4525 effort to facilitate running multiple instances of the entire
4526 regression test suite in parallel without issue.
4527 test_support.bind_port() has been fixed such that it will always
4528 return a unique port -- which wasn't always the case with the
4529 previous implementation, especially if socket options had been set
4530 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4531 new implementation of bind_port() will actually raise an exception
4532 if it is passed an AF_INET/SOCK_STREAM socket with either the
4533 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4534 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4535 the socket it's been passed. This currently only applies to
4536 Windows. This option prevents any other sockets from binding to the
4537 host/port we've bound to, thus removing the possibility of the
4538 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4539 when a second SOCK_STREAM socket binds and accepts to a host/port
4540 that's already been bound by another socket. The optional preferred
4541 port parameter to bind_port() has been removed. Under no
4542 circumstances should tests be hard coding ports!
4543
4544 test_support.find_unused_port() has also been introduced, which will
4545 pass a temporary socket object to bind_port() in order to obtain an
4546 unused port. The temporary socket object is then closed and
4547 deleted, and the port is returned. This method should only be used
4548 for obtaining an unused port in order to pass to an external program
4549 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4550 a parameter to a server-oriented class that doesn't give you direct
4551 access to the underlying socket used.
4552
4553 Finally, test_support.HOST has been introduced, which should be used
4554 for the host argument of any relevant socket calls (i.e. bind and
4555 connect).

4831
Fred Drakea8ee94b2008-03-01 02:45:07 +00004832- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004833 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004834
Georg Brandlad61bc82008-02-23 15:11:18 +00004835- Issue #2067: file.__exit__() now calls subclasses' close() method.
4836
4837- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004838
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004839- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00004840 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00004841
Eric Smitha73fbe72008-02-23 03:09:44 +00004842- Added the future_builtins module, which contains hex() and oct().
4843 These are the PEP 3127 version of these functions, designed to be
4844 compatible with the hex() and oct() builtins from Python 3.0. They
4845 differ slightly in their output formats from the existing, unchanged
4846 Python 2.6 builtins. The expected usage of the future_builtins
4847 module is:
4848 from future_builtins import hex, oct
4849
Eric Smith7ef40bf2008-02-20 23:34:22 +00004850- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4851 exponents for exponents with absolute value < 100. Follows C99
4852 standard. This is a change on Windows, which would use 3 digits.
4853 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4854 so that any alterations it does to the resulting string will be
4855 available in stringlib/formatter.h (for float.__format__).
4856
Eric Smith5a3c1352008-02-19 13:21:56 +00004857- Implemented PEP 3101, Advanced String Formatting. This adds a new
4858 builtin format(); a format() method for str and unicode; a
4859 __format__() method to object, str, unicode, int, long, float, and
4860 datetime; the class string.Formatter; and the C API
4861 PyObject_Format().
4862
Georg Brandl3ee81df2008-05-17 18:14:43 +00004863- Fixed several potential crashes, all caused by specially crafted
4864 __del__ methods exploiting objects in temporarily inconsistent
4865 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004866
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004867- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004868 prevent a possible crash: an Abstract Base Class would try to access
4869 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004870
Georg Brandl3ee81df2008-05-17 18:14:43 +00004871- Fixed repr() and str() of complex numbers with infinity or nan as
4872 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004873
Georg Brandl3ee81df2008-05-17 18:14:43 +00004874- Clear all free lists during a gc.collect() of the highest generation
4875 in order to allow pymalloc to free more arenas. Python may give back
4876 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004877
Georg Brandl3ee81df2008-05-17 18:14:43 +00004878- Issue #2045: Fix an infinite recursion triggered when printing a
4879 subclass of collections.defaultdict, if its default_factory is set
4880 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004881
Christian Heimesf75dbef2008-02-08 00:11:31 +00004882- Fixed a minor memory leak in dictobject.c. The content of the free
4883 list was not freed on interpreter shutdown.
4884
Georg Brandl21e99f42010-03-07 15:23:59 +00004885- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004886 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004887
Georg Brandl3ee81df2008-05-17 18:14:43 +00004888- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4889 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004890 to compact the internal free lists of pre-allocted ints and floats.
4891
Georg Brandl3ee81df2008-05-17 18:14:43 +00004892- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4893 calls. Python expected the return type int but the fork familie
4894 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004895
Georg Brandl3ee81df2008-05-17 18:14:43 +00004896- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4897 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004898
Georg Brandl3ee81df2008-05-17 18:14:43 +00004899- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4900 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004901

4903 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004904
Georg Brandl3ee81df2008-05-17 18:14:43 +00004905- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4906 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004907
Georg Brandl3ee81df2008-05-17 18:14:43 +00004908- Patch #1473257: generator objects gain a gi_code attribute. This is
4909 the same object as the func_code attribute of the function that
4910 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004911
Georg Brandl3ee81df2008-05-17 18:14:43 +00004912- Issue #1920: "while 0" statements were completely removed by the
4913 compiler, even in the presence of an "else" clause, which is
4914 supposed to be run when the condition is false. Now the compiler
4915 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004916
Guido van Rossumeead05f2008-01-24 18:21:02 +00004917- A few crashers fixed: weakref_in_del.py (issue #1377858);
4918 loosing_dict_ref.py (issue #1303614, test67.py);
4919 borrowed_ref_[34].py (not in tracker).
4920
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004921- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004922 suppressed while an extension is loaded by calling SetErrorMode in
4923 dynload_win.c. The error is still reported properly.
4924
Georg Brandl3ee81df2008-05-17 18:14:43 +00004925- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004926 several extension methods and modules do not work without unicode
4927 support.
4928
Georg Brandl26543b12008-01-21 18:36:51 +00004929- Issue #1882: when compiling code from a string, encoding cookies in the
4930 second line of code were not always recognized correctly.
4931
Georg Brandl14404b62008-01-19 19:27:05 +00004932- Issue #1679: "0x" was taken as a valid integer literal.
4933
Georg Brandl6caad7d2008-01-26 14:19:22 +00004934- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004935 added.
4936
Christian Heimesc94e2b52008-01-14 04:13:37 +00004937- sys.float_info / PyFloat_GetInfo: The floating point information
4938 object was converted from a dict to a specialized structseq object.
4939
Georg Brandl3ee81df2008-05-17 18:14:43 +00004940- Patch #1816: Added sys.flags structseq. It exposes the status of
4941 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004942
Georg Brandl3ee81df2008-05-17 18:14:43 +00004943- Objects/structseq.c: Implemented new structseq representation. The
4944 patch makes structseqs (e.g. the return value of os.stat) more
4945 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004946
Georg Brandl3ee81df2008-05-17 18:14:43 +00004947- Patch #1700288: added a type attribute cache that caches method
4948 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004949
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004950- Bug #1776: __import__() no longer accepts filenames on any platform.

4954
Georg Brandl3ee81df2008-05-17 18:14:43 +00004955- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4956 envvar and sys.dont_write_bytecode attribute. All these can be set
4957 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004958
Georg Brandl3ee81df2008-05-17 18:14:43 +00004959- Improve some exception messages when Windows fails to load an
4960 extension module. Now we get for example '%1 is not a valid Win32
4961 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004962
Georg Brandl3ee81df2008-05-17 18:14:43 +00004963- Bug #1481296: Fixed long(float('nan')) != 0L.

4966 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004967
Christian Heimes0a8143f2007-12-18 23:22:54 +00004968- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004969 and INF. float("nan"), float("inf") and float("-inf") now work on
4970 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004971
Georg Brandl3ee81df2008-05-17 18:14:43 +00004972- Compiler now generates simpler and faster code for dictionary
4973 literals. The oparg for BUILD_MAP now indicates an estimated
4974 dictionary size. There is a new opcode, STORE_MAP, for adding
4975 entries to the dictionary.

5007 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005008
Georg Brandl3ee81df2008-05-17 18:14:43 +00005009- Issue #1265: Fix a problem with sys.settrace, if the tracing
5010 function uses a generator expression when at the same time the
5011 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005012
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005013- sets and frozensets now have an isdisjoint() method.
5014

Georg Brandl3ee81df2008-05-17 18:14:43 +00005020 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5021 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005022
Georg Brandl3ee81df2008-05-17 18:14:43 +00005023- Issue #1686386: Tuple's tp_repr did not take into account the
5024 possibility of having a self-referential tuple, which is possible
5025 from C code. Nor did object's tp_str consider that a type's tp_str
5026 could do something that could lead to an inifinite recursion.
5027 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5028 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005029
Georg Brandl3ee81df2008-05-17 18:14:43 +00005030- Issue #1164: It was possible to trigger deadlock when using the
5031 'print' statement to write to a file since the GIL was not released
5032 as needed. Now PyObject_Print() does the right thing along with
5033 various tp_print implementations of the built-in types and those in
5034 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005036- Issue #1147: Exceptions were directly allowing string exceptions in
5037 their throw() method even though string exceptions no longer
5038 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005040- Issue #1096: Prevent a segfault from getting the repr of a very
5041 deeply nested list by using the recursion counter.

Brett Cannon1e534b52007-09-07 04:18:30 +00005043- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005044 PyObject_Call() never calling back out to Python code to trigger
5045 recursion depth updates/checks. Required the creation of a static
5046 RuntimeError instance in case normalizing an exception put the
5047 recursion check value past its limit. Fixes crashers
5048 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00005063- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005064 __*__ attributes. (Some already existed, e.g., __doc__ and
5065 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005066
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005067- Add -3 option to the interpreter to warn about features that are

5071 calls.
5072
Collin Winter62903052007-05-18 23:11:24 +00005073- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005074 "except E as target:". This is to provide forwards compatibility
5075 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005076
Brett Cannon229cee22007-05-05 01:34:02 +00005077- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005082- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005083 setting a plain string, ie don't expand to single letter identifiers.
5084
Raymond Hettinger13936692007-04-11 18:40:58 +00005085- Request #1191699: Slices can now be pickled.
5086
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005087- Request #1193128: str.translate() now allows a None argument for
5088 translations that only remove characters without re-mapping the
5089 remaining characters.
5090
Georg Brandl5cb76c12007-03-21 09:00:39 +00005091- Patch #1682205: a TypeError while unpacking an iterable is no longer

5095
Guido van Rossum143b5642007-03-23 04:58:42 +00005096- Bug #1683368: The object.__init__() and object.__new__() methods are
5097 now stricter in rejecting excess arguments. The only time when
5098 either allows excess arguments is when it is not overridden and the
5099 other one is. For backwards compatibility, when both are
5100 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005101 warning later). Also, type.__init__() insists on the same signature
5102 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005103
Georg Brandl3ee81df2008-05-17 18:14:43 +00005104- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5105 object to complex using its __complex__() method before falling back
5106 to the __float__() method. Therefore, the functions in the cmath
5107 module now can operate on objects that define a __complex__()
5108 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00005126- Bug #1678647: write a newline after printing an exception in any
5127 case, even when converting the value to a string failed.
5128
Georg Brandl871f1bc2007-03-12 13:17:36 +00005129- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005130 its argument, if it exists. If not, it will work like before. This
5131 allows customizing the output of dir() in the presence of a
5132 __getattr__().

5141 parthensized forms. This means complex(repr(x)) now works instead of
5142 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005143
Georg Brandlaa2321b2007-03-07 00:40:28 +00005144- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005145 makes the filenames the warning module prints much more sensible
5146 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00005159- Patch #1674228: when assigning a slice (old-style), check for the
5160 sq_ass_slice instead of the sq_slice slot.
5161
Georg Brandl3ee81df2008-05-17 18:14:43 +00005162- When printing an unraisable error, don't print exceptions. before

5773 Python would crash instead of raising an error.
5774

5791 incompatibility since it never made sense with ordinary subclasses
5792 -- the failure just occurred later, with a more cumbersome
5793 exception.

6076 obtained from the TLS negotiation itself. Patch contributed by Bill
6077 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006078
Georg Brandl3ee81df2008-05-17 18:14:43 +00006079- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006080 that the SMTP.starttls() caller no longer needs to call ehlo()
6081 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006082 does not claim to support starttls. Adds the
6083 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

6164 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6165 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00006182 time so that opening a database previously created with the DB_DUP
6183 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6184 opens. Specifically: dictionary assignment to a DB object will
6185 replace all values for a given key when the database allows
6186 duplicate values. DB users should use DB.put(k, v) when they want
6187 to store duplicates; not DB[k] = v.

6194 characters with ASCII value less than 32. Also, it correctly quotes
6195 dots only if they occur on a single line, as opposed to the previous
6196 behavior of quoting dots if they are the second character of any
6197 line.

6520-----
6521
Georg Brandl3ee81df2008-05-17 18:14:43 +00006522- Unified naming convention for free lists and their limits. All free
6523 lists in Object/ are named ``free_list``, the counter ``numfree``
6524 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
6525 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00006526
Georg Brandl3ee81df2008-05-17 18:14:43 +00006527- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6528 to ``PyTuple_SetItem``, it can be used to populate a brand new
6529 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00006530
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006531- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006533- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
6534 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
6535 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006536
6537- Patch #1720595: add T_BOOL to the range of structmember types.
6538
6539- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
6540 ``PyFloat_GetInfo()`` to the float API.
6541
Georg Brandl3ee81df2008-05-17 18:14:43 +00006542- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6543 of w# format code incorrectly truncated the length to an int, even
6544 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6545 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006546
Georg Brandl3ee81df2008-05-17 18:14:43 +00006547- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
6548 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006549
Georg Brandl3ee81df2008-05-17 18:14:43 +00006550- PEP 3123: Provide forward compatibility with Python 3.0, while
6551 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
6552 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006553
Georg Brandl3ee81df2008-05-17 18:14:43 +00006554- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
6555 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006556
6557- Patch #1733960: Allow T_LONGLONG to accept ints.
6558
6559- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
6560
Christian Heimes000a0742008-01-03 22:16:32 +00006561- Added a new API function ``PyImport_ImportModuleNoBlock``.

6564
6565- Fix some leftovers from the conversion from int to Py_ssize_t
6566 (relevant to strings and sequences of more than 2**31 items).
6567
6568- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6569 outside of pystate.c and should not be necessary.
6570
Georg Brandl3ee81df2008-05-17 18:14:43 +00006571- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6572 absolute imports. In earlier versions they might have used relative
6573 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006574
Georg Brandl3ee81df2008-05-17 18:14:43 +00006575- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6576 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006577
Georg Brandl3ee81df2008-05-17 18:14:43 +00006578- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
6579 macro so it can be used as an expression.

6584
Georg Brandl3ee81df2008-05-17 18:14:43 +00006585- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
6586 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6587 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6588 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00006589
Georg Brandl3ee81df2008-05-17 18:14:43 +00006590- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00006603- Removed the macfs module. It had been deprecated since Python 2.5.
6604 This lead to the deprecation of macostools.touched() as it relied
6605 solely on macfs and was a no-op under OS X.
