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

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

529 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +0000873- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000874 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
875 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
876 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

896Core and Builtins
897-----------------
898
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000899- Issue #7301: Add environment variable $PYTHONWARNINGS.
900
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000901- Issue #8329: Don't return the same lists from select.select when no fds are
902 changed.
903
Georg Brandlfee0f442010-05-22 21:26:21 +0000904- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000905 on 64-bit machines. The shift count for either left or right shift is
906 permitted to be up to sys.maxsize.
907
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000908- Ensure that tokenization of identifiers is not affected by locale.
909
Georg Brandlfee0f442010-05-22 21:26:21 +0000910- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +0000911
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000912- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
913
Georg Brandlfee0f442010-05-22 21:26:21 +0000914- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
915 with a non-empty format string. This is an effort to future-proof user
916 code. If a derived class does not currently implement __format__ but later
917 adds its own __format__, it would most likely break user code that had
918 supplied a format string. This will be changed to a DeprecationWaring in
919 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000920
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000921- Issue #8268: Old-style classes (not just instances) now support weak

945
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000946- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000947 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
948 `ssl.OPENSSL_VERSION_NUMBER`.

951
Georg Brandlfee0f442010-05-22 21:26:21 +0000952- Issue #8257: The Decimal construct now accepts a float instance directly,
953 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000954
955 >>> Decimal(1.1)
956 Decimal('1.100000000000000088817841970012523233890533447265625')
957
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000958- collections.Counter() now supports a subtract() method.
959
Georg Brandlfee0f442010-05-22 21:26:21 +0000960- The functools module now has a total_ordering() class decorator to simplify
961 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000962
Georg Brandlfee0f442010-05-22 21:26:21 +0000963- The functools module also adds cmp_to_key() as a tool to transition old-style
964 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +0000965
Georg Brandlfee0f442010-05-22 21:26:21 +0000966- Issue #8294: The Fraction constructor now accepts Decimal and float instances
967 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000968
Georg Brandlfee0f442010-05-22 21:26:21 +0000969- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
970 InvalidOperation instead of returning False. (Comparisons involving a quiet
971 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
972 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000973
Georg Brandlfee0f442010-05-22 21:26:21 +0000974- Issue #2531: Comparison operations between floats and Decimal instances now
975 return a result based on the numeric values of the operands; previously they
976 returned an arbitrary result based on the relative ordering of id(float) and
977 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000978
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000979- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000980 argument `-` which tells it to read files to compile from stdin. Each line is
981 read on demand and the named file is compiled immediately. (Original patch by
982 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000983
Georg Brandlfee0f442010-05-22 21:26:21 +0000984- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +0000987- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
988 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +0000989 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandlfee0f442010-05-22 21:26:21 +0000991- Comparisons using one of <, <=, >, >= between a complex instance and a
992 Fractions instance now raise TypeError instead of returning True/False. This
993 makes Fraction <=> complex comparisons consistent with int <=> complex, float
994 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +0000995
Michael Foorde6410c52010-03-29 20:04:23 +0000996- Addition of ``WeakSet`` to the ``weakref`` module.

1004
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001005- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001006 didn't support chflags() (for example ZFS under FreeBSD). The error is now
1007 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001008
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00001009- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
1010 deprecated.
1011
Georg Brandlfee0f442010-05-22 21:26:21 +00001012- Issue #7860: platform.uname now reports the correct 'machine' type when Python

Vinay Sajipecfa08f2010-03-12 09:16:10 +00001049- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001050 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1051 log file to compute the next rollover time. If the log file does not exist,
1052 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00001053
Georg Brandlba83f822010-03-14 09:50:54 +00001054- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Georg Brandlba83f822010-03-14 09:50:54 +00001062- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
1063 a base64 transfer-encoded payload *after* decoding it; it no longer does.
1064 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001093- Issue #8300: When passing a non-integer argument to struct.pack with any
1094 integer format code, struct.pack first attempts to convert the non-integer
1095 using its __index__ method. If that method is non-existent or raises
1096 TypeError it goes on to try the __int__ method, as described below.
1097
Georg Brandlba83f822010-03-14 09:50:54 +00001098- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1099 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1100 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001101 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1102 inconsistent: __int__ was used for some integer codes but not for others, and
1103 the set of integer codes for which it was used differed between native packing

1505-----------------
1506
Georg Brandlba83f822010-03-14 09:50:54 +00001507- The ``__complex__()`` method is now looked up on the class of instances to
1508 make it consistent with other special methods.

1512
Mark Dickinson1b34d252010-01-01 17:27:30 +00001513- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001514 DeprecationWarning when passed a float argument where an integer was expected.
1515 These functions and methods now raise TypeError instead. The majority of the
1516 effects of this change are in the extension modules, but some core functions
1517 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1518 and many unicode/str methods.

1532 of integers: the result of a/b is now correctly rounded for ints a and b (at
1533 least on IEEE 754 platforms), and in particular does not depend on the
1534 internal representation of a long.

1542
Georg Brandlba83f822010-03-14 09:50:54 +00001543 These executables now work properly with the arch(1) command: ``arch -ppc
1544 python`` will start a universal binary version of python in PPC mode (unlike

1685 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001686

1688 1e50 in absolute value.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001700
Georg Brandlba83f822010-03-14 09:50:54 +00001701- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1702 decimal string that's guaranteed to round back to x under correct rounding
1703 (with round-half-to-even rounding mode). Previously it gave a string based on
1704 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1705 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1706 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001707
Georg Brandlba83f822010-03-14 09:50:54 +00001708- Issue #7117: On almost all platforms: float-to-string and string-to-float
1709 conversions within Python are now correctly rounded. Places these conversions
1710 occur include: str for floats and complex numbers; the float and complex
1711 constructors; old-style and new-style numeric formatting; serialization and
1712 deserialization of floats and complex numbers using marshal, pickle and json;
1713 parsing of float and imaginary literals in Python code; Decimal-to-float
1714 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001715
Georg Brandlba83f822010-03-14 09:50:54 +00001716 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1717 providing correctly-rounded strtod and dtoa C functions. This code is
1718 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1719 the C compiler. There may be a small number of platforms on which correct
1720 operation of this code cannot be guaranteed, so the code is not used: notably,
1721 this applies to platforms where the C double format is not IEEE 754 binary64,
1722 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1723 and Python's configure script is unable to determine how to change the FPU
1724 precision. On these platforms conversions use the platform strtod and dtoa,
1725 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001726
Georg Brandlba83f822010-03-14 09:50:54 +00001727- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1728 uses the correctly-rounded string <-> float conversions described above (when
1729 available), and so produces correctly rounded results that will display nicely
1730 under the float repr. There are two related small changes: (1) round now
1731 accepts any class with an ``__index__()`` method for its second argument (but
1732 no longer accepts floats for the second argument), and (2) an excessively
1733 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1734 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001881- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1882 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1883 but with at least one decimal point and with a default precision
1884 of 12. Previously, the behavior the same but with a default precision of 6.
1885 This more closely matches ``str()``, and reduces surprises when adding
1886 alignment flags to the empty presentation type. This also affects the new
1887 complex.__format__ in the same way.

2084
Georg Brandlba83f822010-03-14 09:50:54 +00002085- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2086 file objects with closefd=False. The file descriptor is still kept open but
2087 the file object behaves like a closed file. The ``FileIO`` object also got a
2088 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002108- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00002111- On windows, ``os.chdir()`` given unicode was not working if
2112 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2113 this code path is really executed because I cannot move to such directory on
2114 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002116- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2117 element is temporarily replaced with an equivalent frozenset. But the
2118 eventual KeyError would always report the empty ``frozenset()`` as the missing
2119 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00002139- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2140 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2141 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2142 of using the replace error handler in PyUnicode_DecodeUTF8().
2143
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002144- Issue #3739: The unicode-internal encoder now reports the number of characters

2146
Georg Brandlba83f822010-03-14 09:50:54 +00002147- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2148 allocator will be automatically disabled when running under Valgrind. This
2149 gives improved memory leak detection when running under Valgrind, while taking
2150 advantage of pymalloc at other times.

3395 the tests if DISPLAY is defined but can't be used.

Antoine Pitrou4698d992009-05-31 14:20:14 +00003397- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
3398 regression tests in parallel, shortening the total runtime.
3399
Georg Brandlba83f822010-03-14 09:50:54 +00003400- Issue #5354: New test support function import_fresh_module() makes it easy to
3401 import both normal and optimised versions of modules. test_heapq and
3402 test_warnings have been adjusted to use it, tests for other modules with both
3403 C and Python implementations in the stdlib can be adjusted to use it over
3404 time.

Georg Brandlba83f822010-03-14 09:50:54 +00003412- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
3413 should cause a test to be skipped are now done using import_module from test
3414 support, which does the conversion.

3516
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003517- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3518 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3519 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3520 ``printf`` function, whereas PyString_FromFormat has an independent
3521 implementation and uses "%zd" on all platforms for size_t values.
3522 This makes a difference on win64, where ``printf`` needs "%Id" to display
3523 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00003525- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3529 object; previously an int would be returned for small values. the __long__
3530 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003540 was correctly parsed but parsing of subsequent arguments failed.
3541
Vinay Sajip35e3b032008-09-01 14:33:59 +00003542- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003543 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3544 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3545 when given a tuple of classes as second argument, were looking up
3546 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3547 type object.
3548
Neal Norwitz18aa3882008-08-24 05:04:52 +00003549- Fix crashes on memory allocation failure found with failmalloc.

3687================================
3688
Barry Warsaw07a4a382008-08-21 01:15:08 +00003689*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003690
3691Core and Builtins
3692-----------------
3693
Guido van Rossumf8402962008-08-20 15:01:50 +00003694- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3695 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3696 extensions do not automatically benefit from the class attribute
3697 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3698 to their tp_flags field if they care. This is a backwards
3699 compatibility feature; in 3.0, all types will use the cache by
3700 default.
3701
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003702- Keyword arguments can now follow starred arguments. (``f(a, *args,
3703 keyword=23)`` is now valid syntax.)
3704
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003705- ctypes function pointers that are COM methods have a boolean True
3706 value again.
3707
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003708- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3709 by denying s# to parse objects that have a releasebuffer procedure,
3710 and introducing s*.
3711
Georg Brandl1e13ea92008-08-11 09:07:59 +00003712- Issue #3537: Fix an assertion failure when an empty but presized dict
3713 object was stored in the freelist.
3714
Mark Dickinsonb6467572008-08-04 21:30:09 +00003715- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3716 ValueError consistently across platforms.
3717
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003718- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3719 (64bit Unix, for example), unichr() would truncate its argument and return
3720 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3721
Neal Norwitze7d8be82008-07-31 17:17:14 +00003722- Apply security patches from Apple.
3723
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003724- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3725 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3726
Antoine Pitrou92f82162008-07-25 22:22:08 +00003727- Issue #1819: function calls with several named parameters are now on
3728 average 35% faster (as measured by pybench).
3729
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003730- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3731 the python debugger steps into a class statement: the free variables (local
3732 variables defined in an outer scope) would be deleted from the outer scope.
3733
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003734- Issue #2620: Overflow checking when allocating or reallocating memory
3735 was not always being done properly in some python types and extension
3736 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3737 all been updated to perform better checks and places in the code that
3738 would previously leak memory on the error path when such an allocation
3739 failed have been fixed.
3740
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003741Library
3742-------
3743
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003744- Issue #3612: Added some missing basic types in ctypes.wintypes.
3745
Benjamin Petersone977ad42008-08-20 01:42:01 +00003746- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3747 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3748
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003749- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3750 version reported by these tools does not necessarily follow the python
3751 version numbering scheme, so the module is less strict when parsing it.
3752
Nick Coghlanf70385a2008-08-18 12:42:46 +00003753- Issue #2235: Added Py3k warnings for types which will become unhashable
3754 under the stricter __hash__ inheritance rules in 3.0. Several types
3755 which did not meet the rules for hash invariants and were already
3756 unhashable in 3.0 have now been explicitly flagged as unhashable in
3757 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3758 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3759
Brett Cannon88f801d2008-08-18 00:46:22 +00003760- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3761 imported into the module but exposed as part of the module's API.
3762
Brett Cannon7b96f072008-08-18 00:41:11 +00003763- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3764
Brett Cannon46225e72008-08-18 00:36:52 +00003765- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
3766
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003767- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3768
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003769- Issue #3575: Incremental decoder's decode function now takes bytearray
3770 by using 's*' instead of 't#'.
3771
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003772- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003773 fails unicode conversion on 2nd parameter. (windows only)
3774
Georg Brandl222e2082010-08-01 22:27:39 +00003775- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003776 in a redirect.
3777
Brett Cannonabe423e2008-08-16 21:47:07 +00003778- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003779 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003780
Facundo Batistaeb90b782008-08-16 14:44:07 +00003781- Issue #2776: fixed small issue when handling an URL with double slash
3782 after a 302 response in the case of not going through a proxy.
3783
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003784- Issue #2676: in the email package, content-type parsing was hanging on
3785 pathological input because of quadratic or exponential behaviour of a
3786 regular expression.
3787
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003788- Issue #3476: binary buffered reading through the new "io" library is now
3789 thread-safe.
3790
Brett Cannonbf3157b2008-08-14 05:00:03 +00003791- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3792 since mimetools itself is deprecated. Because modules are cached, all
3793 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3794
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003795- Issue #3134: shutil referenced undefined WindowsError symbol.
3796
Robert Schuppenies14646332008-08-10 11:01:53 +00003797- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3798 menu entries were not deleted.
3799
Brett Cannon83e81842008-08-09 23:30:55 +00003800- Copied the implementation of reduce() to _functools.reduce() to have a
3801 version that did not raise a DeprecationWarning under -3.
3802
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003803- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3804 a MemoryError rather than silently stop the iteration.
3805
Guido van Rossum59ce9012008-08-09 14:55:34 +00003806- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3807 to _sre.compile() will now be rejected. This should not affect anybody
3808 since the re.compile() function never generates invalid re-bytecode.
3809
Skip Montanaroa032bf42008-08-08 22:52:51 +00003810- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3811 upon first access it can be automatically initialized from the csv file if
3812 it wasn't initialized during instantiation.
3813
Brett Cannon3aa2a492008-08-06 22:28:09 +00003814- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3815 the reload() built-in has been removed.
3816
Brett Cannon7e30b672008-08-04 21:52:25 +00003817- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003818 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00003819 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
3820 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
3821 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
3822 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
3823 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00003824
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00003825- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
3826 raised an AttributeError.
3827
Benjamin Peterson01a24322008-07-28 23:35:27 +00003828- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003829 asking for a specific length. This problem only affected files opened
3830 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003831
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003832- Issue #3449: Update decimal module to use most recent specification
3833 (v. 1.68) and tests (v. 2.58) from IBM.
3834
Georg Brandl222e2082010-08-01 22:27:39 +00003835- Issue #3437: Bug fix in robotparser parsing of Allow: lines.

3839
Georg Brandlf9efabb2008-07-23 15:16:45 +00003840- Deprecate the "ast" parser function aliases.
3841
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003842- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
3843
3844- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3845 invalid arguments.
3846
3847- Issue #3302: Fix several crashes when calling locale's gettext functions
3848 with None arguments.
3849

3851 configuration files.
3852

3854
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003855- Issue #3394: zipfile.writestr sets external attributes when passed a
3856 file name rather than a ZipInfo instance, so files are extracted with
3857 mode 0600 rather than 000 under Unix.
3858
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003859- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3860 argument in python 2.5, this broke code that subclassed Popen to include its
3861 own poll method. Fixed my moving _deadstate to an _internal_poll method.
3862
Martin v. Löwis8dbf3642008-08-01 14:10:26 +00003863Build
3864-----

3869-------------
3870
Nick Coghlan6e8fef02008-08-18 13:14:22 +00003871- Issue #2235: the C API function PyObject_HashNotImplemented and its
3872 interaction with the tp_hash slot (added in 2.6b2) are now documented
3873
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003874- Issue #643841: The language reference now provides more detailed
3875 coverage of the lookup process for special methods. The disclaimers
3876 regarding lack of coverage of new-style classes have also been
3877 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003880What's New in Python 2.6 beta 2?
3881================================
3882
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003883*Release date: 17-Jul-2008*
3884
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003885Core and Builtins
3886-----------------
3887
Georg Brandl3e483f62008-07-16 22:57:41 +00003888- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3889 its methods now allow for items objects that can be converted to
3890 an integer using operator.index().
3891
Mark Dickinson64b7e502008-07-16 09:40:03 +00003892- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3893 produced a ValueError instead of giving the correct float.
3894
Eric Smitha5fa5a22008-07-16 00:11:49 +00003895- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3896 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3897
Mark Dickinson7103aa42008-07-15 19:08:33 +00003898- Issue #3008: the float type has a new instance method 'float.hex'
3899 and a new class method 'float.fromhex' to convert floating-point
3900 numbers to and from hexadecimal strings, respectively.
3901
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003902- Issue #2235: __hash__ is once again inherited by default. To allow
3903 collections.Hashable to remain meaningful in the presence of the
3904 default hash implementation (object.__hash__), it is now possible
3905 to explicit block inheritance of hash by setting __hash__=None at
3906 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3907 level.
3908
Nick Coghlanb028f502008-07-13 14:52:36 +00003909- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3910 the parent module cannot be found while performing an absolute import.
3911 This means that an incorrectly defined __package__ attribute will
3912 now only prevent relative imports in that module rather than causing
3913 all imports from that module to fail.
3914
Nick Coghlan14ff9942008-07-08 14:21:42 +00003915- Issue #2517: Allow unicode messages in Exceptions again by correctly
3916 bypassing the instance dictionary when looking up __unicode__ on
3917 new-style classes.
3918
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003919- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3920 set to a custom object whose write() method happens to install
3921 another file in sys.stdout.
3922
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003923- Issue #3088: Corrected a race condition in classes derived from
3924 threading.local: the first member set by a thread could be saved in
3925 another thread's dictionary.
3926
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003927- Issue #3004: Minor change to slice.indices(): the start and stop
3928 arguments are now treated identically, making the behaviour easier
3929 to describe and understand. For example, slice(None, -10,
3930 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3931 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3932 10, -1).
3933
Georg Brandl278fc502008-07-19 12:46:12 +00003934- Issue #3219: Calling a function with repeated keyword arguments,
3935 f(a=2, a=23), would not cause a syntax error. This was a regression
3936 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003937
Georg Brandl278fc502008-07-19 12:46:12 +00003938- Issue #2862: Make int and float freelist management consistent with
3939 other freelists. Changes their CompactFreeList apis into
3940 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00003941

3943-------
3944
Thomas Heller57adf222008-08-14 19:10:48 +00003945- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3946 api functions without holding the GIL, which could lead to a fatal
3947 error when they failed.
3948
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003949- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00003957- Issue #3125: Remove copy_reg in multiprocessing and replace it with
3958 ForkingPickler.register() to resolve conflict with ctypes.
3959
Vinay Sajip51e65192008-07-18 09:01:10 +00003960- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00003962- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3963 a valid dlerror() message.
3964
Thomas Heller2bad6572008-07-15 17:19:50 +00003965- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3966 incomplete structure was created.
3967
Brett Cannon3d0b9f02008-07-13 01:15:07 +00003968- Issue #3339: dummy_thread.acquire() should not return None.

4383
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004384- On MacOS X it is now possible to install the framework in 64-bit
4385 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004386 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004387
4388 This is controlled by the configure argument ``--with-universal-archs``:
4389
4390 - ``--with-universal-archs=all``: install 4-way universal
4391
4392 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4393
4394 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4395
4396 This option should be used in combination with ``--enable-universalsdk=``.
4397
4398 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

4435 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00004436
Christian Heimese74c8f22008-04-19 02:23:57 +00004437- Added kill, terminate and send_signal(sig) to subprocess.Popen.
4438
Georg Brandl3ee81df2008-05-17 18:14:43 +00004439- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
4440 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00004441
Georg Brandl3ee81df2008-05-17 18:14:43 +00004442- Four new methods were added to the math and cmath modules: acosh,

Georg Brandl3ee81df2008-05-17 18:14:43 +00004448- Issue #1631171: Re-implement the 'warnings' module in C (the
4449 original Python code has been kept as backup). This will allow for
4450 using the 'warning's machinery in such places as the parser where
4451 use of pure Python code is not possible. Both the ``showarning()``
4452 and ``formatwarning()`` gain an optional 'line' argument which is
4453 not called by default for backwards-compatibility reasons. Setting
4454 ``warnings.showwarning()`` to an implementation that lacks support
4455 for the ``line`` argument will raise a DeprecationWarning.

4479
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004480- The getpass module has been improved on Unix. It now uses /dev/tty
4481 by default and uses stderr instead of stdout. A GetPassWarning is
4482 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00004483

4495 removed and replaced by pure python code.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004497- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004498 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004518- Issue #2550: The approach used by client/server code for obtaining
4519 ports to listen on in network-oriented tests has been refined in an
4520 effort to facilitate running multiple instances of the entire
4521 regression test suite in parallel without issue.
4522 test_support.bind_port() has been fixed such that it will always
4523 return a unique port -- which wasn't always the case with the
4524 previous implementation, especially if socket options had been set
4525 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4526 new implementation of bind_port() will actually raise an exception
4527 if it is passed an AF_INET/SOCK_STREAM socket with either the
4528 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4529 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4530 the socket it's been passed. This currently only applies to
4531 Windows. This option prevents any other sockets from binding to the
4532 host/port we've bound to, thus removing the possibility of the
4533 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4534 when a second SOCK_STREAM socket binds and accepts to a host/port
4535 that's already been bound by another socket. The optional preferred
4536 port parameter to bind_port() has been removed. Under no
4537 circumstances should tests be hard coding ports!
4538
4539 test_support.find_unused_port() has also been introduced, which will
4540 pass a temporary socket object to bind_port() in order to obtain an
4541 unused port. The temporary socket object is then closed and
4542 deleted, and the port is returned. This method should only be used
4543 for obtaining an unused port in order to pass to an external program
4544 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4545 a parameter to a server-oriented class that doesn't give you direct
4546 access to the underlying socket used.
4547
4548 Finally, test_support.HOST has been introduced, which should be used
4549 for the host argument of any relevant socket calls (i.e. bind and
4550 connect).

4825-----------------
4826
Fred Drakea8ee94b2008-03-01 02:45:07 +00004827- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004828 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004829
Georg Brandlad61bc82008-02-23 15:11:18 +00004830- Issue #2067: file.__exit__() now calls subclasses' close() method.
4831
4832- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004833
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004834- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00004835 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00004836
Eric Smitha73fbe72008-02-23 03:09:44 +00004837- Added the future_builtins module, which contains hex() and oct().
4838 These are the PEP 3127 version of these functions, designed to be
4839 compatible with the hex() and oct() builtins from Python 3.0. They
4840 differ slightly in their output formats from the existing, unchanged
4841 Python 2.6 builtins. The expected usage of the future_builtins
4842 module is:
4843 from future_builtins import hex, oct
4844
Eric Smith7ef40bf2008-02-20 23:34:22 +00004845- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4846 exponents for exponents with absolute value < 100. Follows C99
4847 standard. This is a change on Windows, which would use 3 digits.
4848 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4849 so that any alterations it does to the resulting string will be
4850 available in stringlib/formatter.h (for float.__format__).
4851
Eric Smith5a3c1352008-02-19 13:21:56 +00004852- Implemented PEP 3101, Advanced String Formatting. This adds a new
4853 builtin format(); a format() method for str and unicode; a
4854 __format__() method to object, str, unicode, int, long, float, and
4855 datetime; the class string.Formatter; and the C API
4856 PyObject_Format().
4857
Georg Brandl3ee81df2008-05-17 18:14:43 +00004858- Fixed several potential crashes, all caused by specially crafted
4859 __del__ methods exploiting objects in temporarily inconsistent
4860 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004861
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004862- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004863 prevent a possible crash: an Abstract Base Class would try to access
4864 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004865
Georg Brandl3ee81df2008-05-17 18:14:43 +00004866- Fixed repr() and str() of complex numbers with infinity or nan as
4867 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004868
Georg Brandl3ee81df2008-05-17 18:14:43 +00004869- Clear all free lists during a gc.collect() of the highest generation
4870 in order to allow pymalloc to free more arenas. Python may give back
4871 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004872
Georg Brandl3ee81df2008-05-17 18:14:43 +00004873- Issue #2045: Fix an infinite recursion triggered when printing a
4874 subclass of collections.defaultdict, if its default_factory is set
4875 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004876
Christian Heimesf75dbef2008-02-08 00:11:31 +00004877- Fixed a minor memory leak in dictobject.c. The content of the free
4878 list was not freed on interpreter shutdown.
4879
Georg Brandl21e99f42010-03-07 15:23:59 +00004880- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004881 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004882
Georg Brandl3ee81df2008-05-17 18:14:43 +00004883- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4884 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004885 to compact the internal free lists of pre-allocted ints and floats.
4886
Georg Brandl3ee81df2008-05-17 18:14:43 +00004887- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4888 calls. Python expected the return type int but the fork familie
4889 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004890
Georg Brandl3ee81df2008-05-17 18:14:43 +00004891- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4892 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004893
Georg Brandl3ee81df2008-05-17 18:14:43 +00004894- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4895 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004896

4898 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004899
Georg Brandl3ee81df2008-05-17 18:14:43 +00004900- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4901 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004902
Georg Brandl3ee81df2008-05-17 18:14:43 +00004903- Patch #1473257: generator objects gain a gi_code attribute. This is
4904 the same object as the func_code attribute of the function that
4905 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004906
Georg Brandl3ee81df2008-05-17 18:14:43 +00004907- Issue #1920: "while 0" statements were completely removed by the
4908 compiler, even in the presence of an "else" clause, which is
4909 supposed to be run when the condition is false. Now the compiler
4910 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004911
Guido van Rossumeead05f2008-01-24 18:21:02 +00004912- A few crashers fixed: weakref_in_del.py (issue #1377858);
4913 loosing_dict_ref.py (issue #1303614, test67.py);
4914 borrowed_ref_[34].py (not in tracker).
4915
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004916- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004917 suppressed while an extension is loaded by calling SetErrorMode in
4918 dynload_win.c. The error is still reported properly.
4919
Georg Brandl3ee81df2008-05-17 18:14:43 +00004920- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004921 several extension methods and modules do not work without unicode
4922 support.
4923
Georg Brandl26543b12008-01-21 18:36:51 +00004924- Issue #1882: when compiling code from a string, encoding cookies in the
4925 second line of code were not always recognized correctly.
4926
Georg Brandl14404b62008-01-19 19:27:05 +00004927- Issue #1679: "0x" was taken as a valid integer literal.
4928
Georg Brandl6caad7d2008-01-26 14:19:22 +00004929- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004930 added.
4931
Christian Heimesc94e2b52008-01-14 04:13:37 +00004932- sys.float_info / PyFloat_GetInfo: The floating point information
4933 object was converted from a dict to a specialized structseq object.
4934
Georg Brandl3ee81df2008-05-17 18:14:43 +00004935- Patch #1816: Added sys.flags structseq. It exposes the status of
4936 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004937
Georg Brandl3ee81df2008-05-17 18:14:43 +00004938- Objects/structseq.c: Implemented new structseq representation. The
4939 patch makes structseqs (e.g. the return value of os.stat) more
4940 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004941
Georg Brandl3ee81df2008-05-17 18:14:43 +00004942- Patch #1700288: added a type attribute cache that caches method
4943 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004944
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004945- Bug #1776: __import__() no longer accepts filenames on any platform.
4946 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004947

4949
Georg Brandl3ee81df2008-05-17 18:14:43 +00004950- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4951 envvar and sys.dont_write_bytecode attribute. All these can be set
4952 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004953
Georg Brandl3ee81df2008-05-17 18:14:43 +00004954- Improve some exception messages when Windows fails to load an
4955 extension module. Now we get for example '%1 is not a valid Win32
4956 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004957
Georg Brandl3ee81df2008-05-17 18:14:43 +00004958- Bug #1481296: Fixed long(float('nan')) != 0L.

4961 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004962
Christian Heimes0a8143f2007-12-18 23:22:54 +00004963- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004964 and INF. float("nan"), float("inf") and float("-inf") now work on
4965 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004966
Georg Brandl3ee81df2008-05-17 18:14:43 +00004967- Compiler now generates simpler and faster code for dictionary
4968 literals. The oparg for BUILD_MAP now indicates an estimated
4969 dictionary size. There is a new opcode, STORE_MAP, for adding
4970 entries to the dictionary.

5002 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005003
Georg Brandl3ee81df2008-05-17 18:14:43 +00005004- Issue #1265: Fix a problem with sys.settrace, if the tracing
5005 function uses a generator expression when at the same time the
5006 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005007
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005008- sets and frozensets now have an isdisjoint() method.

5013
Georg Brandl21e99f42010-03-07 15:23:59 +00005014- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005015 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5016 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005017
Georg Brandl3ee81df2008-05-17 18:14:43 +00005018- Issue #1686386: Tuple's tp_repr did not take into account the
5019 possibility of having a self-referential tuple, which is possible
5020 from C code. Nor did object's tp_str consider that a type's tp_str
5021 could do something that could lead to an inifinite recursion.
5022 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5023 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005024
Georg Brandl3ee81df2008-05-17 18:14:43 +00005025- Issue #1164: It was possible to trigger deadlock when using the
5026 'print' statement to write to a file since the GIL was not released
5027 as needed. Now PyObject_Print() does the right thing along with
5028 various tp_print implementations of the built-in types and those in
5029 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005031- Issue #1147: Exceptions were directly allowing string exceptions in
5032 their throw() method even though string exceptions no longer
5033 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005035- Issue #1096: Prevent a segfault from getting the repr of a very
5036 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005037
Brett Cannon1e534b52007-09-07 04:18:30 +00005038- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005039 PyObject_Call() never calling back out to Python code to trigger
5040 recursion depth updates/checks. Required the creation of a static
5041 RuntimeError instance in case normalizing an exception put the
5042 recursion check value past its limit. Fixes crashers
5043 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00005058- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005059 __*__ attributes. (Some already existed, e.g., __doc__ and
5060 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005061
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005062- Add -3 option to the interpreter to warn about features that are

5064
Georg Brandl2134e752007-05-21 20:34:16 +00005065- Patch #1686487: you can now pass any mapping after '**' in function
5066 calls.
5067
Collin Winter62903052007-05-18 23:11:24 +00005068- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005069 "except E as target:". This is to provide forwards compatibility
5070 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005071
Brett Cannon229cee22007-05-05 01:34:02 +00005072- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005077- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005078 setting a plain string, ie don't expand to single letter identifiers.
5079
Raymond Hettinger13936692007-04-11 18:40:58 +00005080- Request #1191699: Slices can now be pickled.
5081
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005082- Request #1193128: str.translate() now allows a None argument for
5083 translations that only remove characters without re-mapping the
5084 remaining characters.
5085
Georg Brandl5cb76c12007-03-21 09:00:39 +00005086- Patch #1682205: a TypeError while unpacking an iterable is no longer

5090
Guido van Rossum143b5642007-03-23 04:58:42 +00005091- Bug #1683368: The object.__init__() and object.__new__() methods are
5092 now stricter in rejecting excess arguments. The only time when
5093 either allows excess arguments is when it is not overridden and the
5094 other one is. For backwards compatibility, when both are
5095 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005096 warning later). Also, type.__init__() insists on the same signature
5097 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005098
Georg Brandl3ee81df2008-05-17 18:14:43 +00005099- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5100 object to complex using its __complex__() method before falling back
5101 to the __float__() method. Therefore, the functions in the cmath
5102 module now can operate on objects that define a __complex__()
5103 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00005121- Bug #1678647: write a newline after printing an exception in any
5122 case, even when converting the value to a string failed.
5123
Georg Brandl871f1bc2007-03-12 13:17:36 +00005124- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005125 its argument, if it exists. If not, it will work like before. This
5126 allows customizing the output of dir() in the presence of a
5127 __getattr__().

5136 parthensized forms. This means complex(repr(x)) now works instead of
5137 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005138
Georg Brandlaa2321b2007-03-07 00:40:28 +00005139- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005140 makes the filenames the warning module prints much more sensible
5141 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00005154- Patch #1674228: when assigning a slice (old-style), check for the
5155 sq_ass_slice instead of the sq_slice slot.
5156
Georg Brandl3ee81df2008-05-17 18:14:43 +00005157- When printing an unraisable error, don't print exceptions. before

5768 Python would crash instead of raising an error.
5769

5785 accepted in TestSuite.addTest(). This should cause no
5786 incompatibility since it never made sense with ordinary subclasses
5787 -- the failure just occurred later, with a more cumbersome
5788 exception.

6071 obtained from the TLS negotiation itself. Patch contributed by Bill
6072 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006073
Georg Brandl3ee81df2008-05-17 18:14:43 +00006074- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006075 that the SMTP.starttls() caller no longer needs to call ehlo()
6076 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006077 does not claim to support starttls. Adds the
6078 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00006177 time so that opening a database previously created with the DB_DUP
6178 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6179 opens. Specifically: dictionary assignment to a DB object will
6180 replace all values for a given key when the database allows
6181 duplicate values. DB users should use DB.put(k, v) when they want
6182 to store duplicates; not DB[k] = v.

6189 characters with ASCII value less than 32. Also, it correctly quotes
6190 dots only if they occur on a single line, as opposed to the previous
6191 behavior of quoting dots if they are the second character of any
6192 line.

6515-----
6516
Georg Brandl3ee81df2008-05-17 18:14:43 +00006517- Unified naming convention for free lists and their limits. All free
6518 lists in Object/ are named ``free_list``, the counter ``numfree``
6519 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
6520 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00006521
Georg Brandl3ee81df2008-05-17 18:14:43 +00006522- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6523 to ``PyTuple_SetItem``, it can be used to populate a brand new
6524 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00006525
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006526- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006528- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
6529 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
6530 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006531
6532- Patch #1720595: add T_BOOL to the range of structmember types.
6533
6534- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
6535 ``PyFloat_GetInfo()`` to the float API.
6536
Georg Brandl3ee81df2008-05-17 18:14:43 +00006537- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6538 of w# format code incorrectly truncated the length to an int, even
6539 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6540 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006541
Georg Brandl3ee81df2008-05-17 18:14:43 +00006542- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
6543 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006544
Georg Brandl3ee81df2008-05-17 18:14:43 +00006545- PEP 3123: Provide forward compatibility with Python 3.0, while
6546 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
6547 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006548
Georg Brandl3ee81df2008-05-17 18:14:43 +00006549- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
6550 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006551
6552- Patch #1733960: Allow T_LONGLONG to accept ints.
6553
6554- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
6555
Christian Heimes000a0742008-01-03 22:16:32 +00006556- Added a new API function ``PyImport_ImportModuleNoBlock``.

6559
6560- Fix some leftovers from the conversion from int to Py_ssize_t
6561 (relevant to strings and sequences of more than 2**31 items).
6562
6563- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6564 outside of pystate.c and should not be necessary.
6565
Georg Brandl3ee81df2008-05-17 18:14:43 +00006566- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6567 absolute imports. In earlier versions they might have used relative
6568 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006569
Georg Brandl3ee81df2008-05-17 18:14:43 +00006570- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6571 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006572
Georg Brandl3ee81df2008-05-17 18:14:43 +00006573- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
6574 macro so it can be used as an expression.

6579
Georg Brandl3ee81df2008-05-17 18:14:43 +00006580- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
6581 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6582 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6583 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00006584
Georg Brandl3ee81df2008-05-17 18:14:43 +00006585- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00006598- Removed the macfs module. It had been deprecated since Python 2.5.
6599 This lead to the deprecation of macostools.touched() as it relied
6600 solely on macfs and was a no-op under OS X.
