14 long for a class whose __long__ method returns a plain int. This
15 fixes an interpreter crash when initializing an instance of a long
16 subclass from an object whose __long__ method returns a plain int.
17
Benjamin Petersona5d5cc42010-10-02 00:08:58 +000018- Issue #10006: type.__abstractmethods__ now raises an AttributeError.
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

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

61 characters that appear inside quoted strings in email addresses.
62
R. David Murray20ad3632010-10-01 15:48:49 +000063- Issue #10004: quoprimime no longer generates a traceback when confronted
64 with invalid characters after '=' in a Q-encoded word.

76
Antoine Pitrou2c7d6852010-09-23 19:55:24 +000077- Issue #9928: Properly initialize the types exported by the bz2 module.
78
Antoine Pitrou6391b342010-09-14 18:48:19 +000079- Issue #9854: The default read() implementation in io.RawIOBase now
80 handles non-blocking readinto() returning None correctly.
81
Antoine Pitrouf7f390a2010-09-14 14:37:18 +000082- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
83 SSLSocket.sendto() to match the corresponding socket methods. Also,
84 fix various SSLSocket methods to raise socket.error rather than an
85 unhelpful TypeError when called on an unconnected socket. Original patch
86 by Andrew Bennetts.
87
Raymond Hettinger74f869e2010-09-13 22:14:36 +000088- Issue #9826: OrderedDict.__repr__ can now handle self-referential
89 values: d['x'] = d.

94 ZipFile.open()) could return more bytes than requested.
95
Raymond Hettinger20397532010-09-12 02:11:45 +000096- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
97 This prevents user-created self-referencing ordered dictionaries from
98 becoming permanently uncollectable GC garbage. The downside is that
99 removing __del__ means that the internal doubly-linked list has to wait for
100 GC collection rather than freeing memory immediately when the refcnt drops
101 to zero.
102
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000103- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
104 different internal state for small values of n. Fixed by salting the
105 value.
106
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000107- Issue #9792: In case of connection failure, socket.create_connection()
108 would swallow the exception and raise a new one, making it impossible
109 to fetch the original errno, or to filter timeout errors. Now the
110 original error is re-raised.
111
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000112- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
113 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
114 be updated back after the system call. Original patch by Brian Brazil.
115
Antoine Pitroudca9de92010-09-04 17:52:26 +0000116- Issue #1100562: Fix deep-copying of objects derived from the list and
117 dict types. Patch by Michele Orrù and Björn Lindqvist.
118
Fred Drakea1e627d2010-09-03 03:55:50 +0000119- Issue #7005: Fixed output of None values for RawConfigParser.write and
120 ConfigParser.write.
121
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000122- Issue #808164: Fixed socket.close to avoid references to globals, to
123 avoid issues when socket.close is called from a __del__ method.
124
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +0000125- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
126 falling into recursion.
127
R. David Murray7c4bf552010-08-25 01:45:57 +0000128- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
129 character years even if the message contains RFC822 two character years.
130
Daniel Stutzbach91287322010-08-24 21:09:30 +0000131- Issue #8750: Fixed MutableSet's methods to correctly handle
132 reflexive operations, namely x -= x and x ^= x.
133
Victor Stinnercaafd772010-09-08 10:51:01 +0000134- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing
Giampaolo Rodolà8664d742010-08-23 22:48:51 +0000135 error handling when accepting a new connection.
136
Giampaolo Rodolà63308d72010-08-23 21:58:47 +0000137- Issue #658749: asyncore's connect() method now correctly interprets winsock
138 errors.

Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000145- Issue #9617: Signals received during a low-level write operation aren't
146 ignored by the buffered IO layer anymore.
147
Benjamin Peterson52c36052010-08-21 03:03:22 +0000148- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
149 are not held onto after they are deleted elsewhere.
150
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000151- Issue #9626: the view methods for collections.OrderedDict() were returning
152 the unordered versions inherited from dict. Those methods are now
153 overridden to provide ordered views.
154
Éric Araujo0389ae62010-08-14 03:07:46 +0000155- Issue #8688: MANIFEST files created by distutils now include a magic
156 comment indicating they are generated. Manually maintained MANIFESTs
157 without this marker will not be overwritten or removed.
158
Antoine Pitroue1436d12010-08-12 15:25:51 +0000159- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
160 and a BadZipfile error is raised if it doesn't match (as used to be the

162
Antoine Pitroucb4f47c2010-08-11 13:40:17 +0000163- Issue #9550: a BufferedReader could issue an additional read when the
164 original read request had been satisfied, which could block indefinitely
165 when the underlying raw IO channel was e.g. a socket. Report and original
166 patch by Jason V. Miller.
167
Fred Drake0a1fa0e2010-08-10 13:09:54 +0000168- Issue #9551: Don't raise TypeError when setting the value to None for

173
Antoine Pitrou99009162010-08-09 22:51:24 +0000174- Issue #3757: thread-local objects now support cyclic garbage collection.
175 Thread-local objects involved in reference cycles will be deallocated
176 timely by the cyclic GC, even if the underlying thread is still running.
177

188 behavior was wrong.
189

540 of the number of bytes specified by the start byte.
541 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
542 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

Georg Brandlfee0f442010-05-22 21:26:21 +0000898- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000899 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
900 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
901 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

921Core and Builtins
922-----------------
923
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000924- Issue #7301: Add environment variable $PYTHONWARNINGS.
925
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000926- Issue #8329: Don't return the same lists from select.select when no fds are
927 changed.
928
Georg Brandlfee0f442010-05-22 21:26:21 +0000929- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000930 on 64-bit machines. The shift count for either left or right shift is
931 permitted to be up to sys.maxsize.
932
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000933- Ensure that tokenization of identifiers is not affected by locale.
934
Georg Brandlfee0f442010-05-22 21:26:21 +0000935- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +0000936
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000937- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
938
Georg Brandlfee0f442010-05-22 21:26:21 +0000939- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
940 with a non-empty format string. This is an effort to future-proof user
941 code. If a derived class does not currently implement __format__ but later
942 adds its own __format__, it would most likely break user code that had
943 supplied a format string. This will be changed to a DeprecationWaring in
944 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000945
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000946- Issue #8268: Old-style classes (not just instances) now support weak

Benjamin Peterson96545892010-03-21 20:21:00 +0000954- Issue #6474: Make error message from passing an inadequate number of keyword
955 arguments to a function correct.
956

970
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000971- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000972 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
973 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000974
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000975- Issue #8310: Allow dis to examine new style classes.
976
Georg Brandlfee0f442010-05-22 21:26:21 +0000977- Issue #8257: The Decimal construct now accepts a float instance directly,
978 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000979
980 >>> Decimal(1.1)
981 Decimal('1.100000000000000088817841970012523233890533447265625')
982
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000983- collections.Counter() now supports a subtract() method.
984
Georg Brandlfee0f442010-05-22 21:26:21 +0000985- The functools module now has a total_ordering() class decorator to simplify
986 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000987
Georg Brandlfee0f442010-05-22 21:26:21 +0000988- The functools module also adds cmp_to_key() as a tool to transition old-style
989 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +0000990
Georg Brandlfee0f442010-05-22 21:26:21 +0000991- Issue #8294: The Fraction constructor now accepts Decimal and float instances
992 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000993
Georg Brandlfee0f442010-05-22 21:26:21 +0000994- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
995 InvalidOperation instead of returning False. (Comparisons involving a quiet
996 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
997 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000998
Georg Brandlfee0f442010-05-22 21:26:21 +0000999- Issue #2531: Comparison operations between floats and Decimal instances now
1000 return a result based on the numeric values of the operands; previously they
1001 returned an arbitrary result based on the relative ordering of id(float) and
1002 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001003
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001004- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001005 argument `-` which tells it to read files to compile from stdin. Each line is
1006 read on demand and the named file is compiled immediately. (Original patch by
1007 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001008
Georg Brandlfee0f442010-05-22 21:26:21 +00001009- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00001012- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1013 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001014 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001015
Georg Brandlfee0f442010-05-22 21:26:21 +00001016- Comparisons using one of <, <=, >, >= between a complex instance and a
1017 Fractions instance now raise TypeError instead of returning True/False. This
1018 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1019 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001020
Michael Foorde6410c52010-03-29 20:04:23 +00001021- Addition of ``WeakSet`` to the ``weakref`` module.

1029
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001030- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001031 didn't support chflags() (for example ZFS under FreeBSD). The error is now
1032 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001033
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00001034- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
1035 deprecated.
1036
Georg Brandlfee0f442010-05-22 21:26:21 +00001037- Issue #7860: platform.uname now reports the correct 'machine' type when Python

1045 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00001046

Vinay Sajipecfa08f2010-03-12 09:16:10 +00001074- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001075 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1076 log file to compute the next rollover time. If the log file does not exist,
1077 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00001078
Georg Brandlba83f822010-03-14 09:50:54 +00001079- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001118- Issue #8300: When passing a non-integer argument to struct.pack with any
1119 integer format code, struct.pack first attempts to convert the non-integer
1120 using its __index__ method. If that method is non-existent or raises
1121 TypeError it goes on to try the __int__ method, as described below.

Georg Brandlba83f822010-03-14 09:50:54 +00001123- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1124 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1125 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001126 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1127 inconsistent: __int__ was used for some integer codes but not for others, and
1128 the set of integer codes for which it was used differed between native packing
1129 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00001337- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
1338 now also used by regrtest to run all the tests in a temporary directory. The
1339 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
1340 Xicluna who helped with the patch.

1378 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1379 returning NULL. The macro now returns a statically allocated empty string
1380 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00001433 file position when calling `truncate()`. It would previously change the file
1434 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001435 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1436
Georg Brandlba83f822010-03-14 09:50:54 +00001437- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1438 class used to represent files stored inside an archive. The new
1439 implementation is significantly faster and can be wrapped in a
1440 ``io.BufferedReader`` object for more speedups. It also solves an issue
1441 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
1442 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00001452- Issue #7748: Since unicode values are supported for some metadata options in
1453 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1454 encoded string for them. This ensures that the upload and register commands
1455 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00001532- The ``__complex__()`` method is now looked up on the class of instances to

1537
Mark Dickinson1b34d252010-01-01 17:27:30 +00001538- Issue #5080: A number of functions and methods previously produced a

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001711
Georg Brandlba83f822010-03-14 09:50:54 +00001712- Remove switch from "%f" formatting to "%g" formatting for floats larger than

Georg Brandlba83f822010-03-14 09:50:54 +00001726- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1727 decimal string that's guaranteed to round back to x under correct rounding
1728 (with round-half-to-even rounding mode). Previously it gave a string based on
1729 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1730 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1731 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001732
Georg Brandlba83f822010-03-14 09:50:54 +00001733- Issue #7117: On almost all platforms: float-to-string and string-to-float
1734 conversions within Python are now correctly rounded. Places these conversions
1735 occur include: str for floats and complex numbers; the float and complex
1736 constructors; old-style and new-style numeric formatting; serialization and
1737 deserialization of floats and complex numbers using marshal, pickle and json;
1738 parsing of float and imaginary literals in Python code; Decimal-to-float
1739 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001740
Georg Brandlba83f822010-03-14 09:50:54 +00001741 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1742 providing correctly-rounded strtod and dtoa C functions. This code is
1743 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1744 the C compiler. There may be a small number of platforms on which correct
1745 operation of this code cannot be guaranteed, so the code is not used: notably,
1746 this applies to platforms where the C double format is not IEEE 754 binary64,
1747 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1748 and Python's configure script is unable to determine how to change the FPU
1749 precision. On these platforms conversions use the platform strtod and dtoa,
1750 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001751
Georg Brandlba83f822010-03-14 09:50:54 +00001752- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1753 uses the correctly-rounded string <-> float conversions described above (when
1754 available), and so produces correctly rounded results that will display nicely
1755 under the float repr. There are two related small changes: (1) round now
1756 accepts any class with an ``__index__()`` method for its second argument (but
1757 no longer accepts floats for the second argument), and (2) an excessively
1758 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1759 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001902 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1903 (2) parsing of strings representing infinities and nans was locale aware; and
1904 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001906- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1907 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1908 but with at least one decimal point and with a default precision
1909 of 12. Previously, the behavior the same but with a default precision of 6.
1910 This more closely matches ``str()``, and reduces surprises when adding
1911 alignment flags to the empty presentation type. This also affects the new
1912 complex.__format__ in the same way.
1913
1914- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
1915 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00001977 untrackable objects are not tracked by the garbage collector. This can reduce

2051
Georg Brandlba83f822010-03-14 09:50:54 +00002052- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2053 existing .py counterpart, override the co_filename attributes of all code
2054 objects if the original filename is obsolete (which can happen if the file has
2055 been renamed, moved, or if it is accessed through different paths). Patch by
2056 Ziga Seilnacht and Jean-Paul Calderone.

Georg Brandl6425a2f2008-12-28 11:54:53 +00002075- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00002076 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.

Georg Brandlba83f822010-03-14 09:50:54 +00002095- Issue #4445: Replace ``sizeof(PyStringObject)`` with
2096 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2097 instances. On a typical machine this saves 3 bytes of memory (on average) per
2098 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002100- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
2101 interpreter to abort ("Fatal Python error: Could not reset the stack!")
2102 instead of throwing a MemoryError.
2103
Georg Brandlba83f822010-03-14 09:50:54 +00002104- Issue #3689: The list reversed iterator now supports __length_hint__ instead

Benjamin Petersonc078f922008-11-21 22:27:24 +00002107- Issue #4367: Python would segfault during compiling when the unicodedata

2109
Georg Brandlba83f822010-03-14 09:50:54 +00002110- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2111 file objects with closefd=False. The file descriptor is still kept open but
2112 the file object behaves like a closed file. The ``FileIO`` object also got a
2113 new readonly attribute ``closefd``.

Benjamin Peterson46cc6d12008-11-19 21:49:09 +00002115- Issue #4348: Some bytearray methods returned that didn't cause any change to
2116 the bytearray, returned the same bytearray instead of a copy.
2117

Benjamin Petersonbdca9422008-10-26 20:21:13 +00002130- Issue #4209: Enabling unicode_literals and the print_function in the same
2131 __future__ import didn't work.
2132
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002133- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00002134 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00002136- On windows, ``os.chdir()`` given unicode was not working if
2137 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2138 this code path is really executed because I cannot move to such directory on
2139 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00002140
Georg Brandlba83f822010-03-14 09:50:54 +00002141- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2142 element is temporarily replaced with an equivalent frozenset. But the
2143 eventual KeyError would always report the empty ``frozenset()`` as the missing
2144 key. Now it correctly refers to the initial element.

2162 returned them on 64bit platforms.
2163
Walter Dörwalded960ac2009-05-03 22:36:33 +00002164- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2165 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2166 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2167 of using the replace error handler in PyUnicode_DecodeUTF8().
2168
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002169- Issue #3739: The unicode-internal encoder now reports the number of characters
2170 consumed like any other encoder (instead of the number of bytes).
2171
Georg Brandlba83f822010-03-14 09:50:54 +00002172- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2173 allocator will be automatically disabled when running under Valgrind. This
2174 gives improved memory leak detection when running under Valgrind, while taking
2175 advantage of pymalloc at other times.

3406 __all__ attribute, rather than using a hardcoded and incomplete list.
3407
R. David Murray14dcd432009-10-14 13:58:07 +00003408- Issue #7058: Added save/restore for things like sys.argv and cwd to
3409 runtest_inner in regrtest, with warnings if the called test modifies them,
3410 and a new section in the summary report at the end.

Brett Cannone7e941e2009-09-03 21:25:21 +00003414- Issue #6806: test_platform failed under OS X 10.6.0 because ``sw_ver`` leaves
3415 off the trailing 0 in the version number.
3416
Guilherme Polo7f146ab2009-06-21 17:22:50 +00003417- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
3418 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00003419 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
3420 the tests if DISPLAY is defined but can't be used.

Antoine Pitrou4698d992009-05-31 14:20:14 +00003422- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
3423 regression tests in parallel, shortening the total runtime.
3424
Georg Brandlba83f822010-03-14 09:50:54 +00003425- Issue #5354: New test support function import_fresh_module() makes it easy to
3426 import both normal and optimised versions of modules. test_heapq and
3427 test_warnings have been adjusted to use it, tests for other modules with both
3428 C and Python implementations in the stdlib can be adjusted to use it over
3429 time.

3436
Georg Brandlba83f822010-03-14 09:50:54 +00003437- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
3438 should cause a test to be skipped are now done using import_module from test
3439 support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003540- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3541
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003542- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3543 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3544 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3545 ``printf`` function, whereas PyString_FromFormat has an independent
3546 implementation and uses "%zd" on all platforms for size_t values.
3547 This makes a difference on win64, where ``printf`` needs "%Id" to display
3548 64bit values.
3549
Benjamin Peterson97179b02008-09-09 20:55:01 +00003550- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3554 object; previously an int would be returned for small values. the __long__
3555 method is allowed to return either an int or a long, but the behaviour of
3556 float objects should not change to respect backward compatibility.
3557
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003558- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00003564 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003565 was correctly parsed but parsing of subsequent arguments failed.
3566
Vinay Sajip35e3b032008-09-01 14:33:59 +00003567- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003568 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3569 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3570 when given a tuple of classes as second argument, were looking up
3571 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3572 type object.
3573
Neal Norwitz18aa3882008-08-24 05:04:52 +00003574- Fix crashes on memory allocation failure found with failmalloc.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003711What's New in Python 2.6 beta 3?
3712================================
3713
Barry Warsaw07a4a382008-08-21 01:15:08 +00003714*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003715
3716Core and Builtins
3717-----------------
3718
Guido van Rossumf8402962008-08-20 15:01:50 +00003719- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3720 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3721 extensions do not automatically benefit from the class attribute
3722 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3723 to their tp_flags field if they care. This is a backwards
3724 compatibility feature; in 3.0, all types will use the cache by
3725 default.
3726
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003727- Keyword arguments can now follow starred arguments. (``f(a, *args,
3728 keyword=23)`` is now valid syntax.)
3729
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003730- ctypes function pointers that are COM methods have a boolean True
3731 value again.
3732
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003733- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3734 by denying s# to parse objects that have a releasebuffer procedure,
3735 and introducing s*.
3736
Georg Brandl1e13ea92008-08-11 09:07:59 +00003737- Issue #3537: Fix an assertion failure when an empty but presized dict
3738 object was stored in the freelist.
3739
Mark Dickinsonb6467572008-08-04 21:30:09 +00003740- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3741 ValueError consistently across platforms.
3742
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003743- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3744 (64bit Unix, for example), unichr() would truncate its argument and return
3745 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3746
Neal Norwitze7d8be82008-07-31 17:17:14 +00003747- Apply security patches from Apple.
3748
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003749- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3750 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3751
Antoine Pitrou92f82162008-07-25 22:22:08 +00003752- Issue #1819: function calls with several named parameters are now on
3753 average 35% faster (as measured by pybench).
3754
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003755- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3756 the python debugger steps into a class statement: the free variables (local
3757 variables defined in an outer scope) would be deleted from the outer scope.
3758
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003759- Issue #2620: Overflow checking when allocating or reallocating memory
3760 was not always being done properly in some python types and extension
3761 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3762 all been updated to perform better checks and places in the code that
3763 would previously leak memory on the error path when such an allocation
3764 failed have been fixed.

3768
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003769- Issue #3612: Added some missing basic types in ctypes.wintypes.
3770
Benjamin Petersone977ad42008-08-20 01:42:01 +00003771- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3772 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3773
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003774- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3775 version reported by these tools does not necessarily follow the python
3776 version numbering scheme, so the module is less strict when parsing it.
3777
Nick Coghlanf70385a2008-08-18 12:42:46 +00003778- Issue #2235: Added Py3k warnings for types which will become unhashable
3779 under the stricter __hash__ inheritance rules in 3.0. Several types
3780 which did not meet the rules for hash invariants and were already
3781 unhashable in 3.0 have now been explicitly flagged as unhashable in
3782 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3783 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3784
Brett Cannon88f801d2008-08-18 00:46:22 +00003785- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3786 imported into the module but exposed as part of the module's API.
3787
Brett Cannon7b96f072008-08-18 00:41:11 +00003788- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3789
Brett Cannon46225e72008-08-18 00:36:52 +00003790- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
3791
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003792- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3793
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003794- Issue #3575: Incremental decoder's decode function now takes bytearray
3795 by using 's*' instead of 't#'.
3796
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003797- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003798 fails unicode conversion on 2nd parameter. (windows only)
3799
Georg Brandl222e2082010-08-01 22:27:39 +00003800- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003801 in a redirect.
3802
Brett Cannonabe423e2008-08-16 21:47:07 +00003803- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003804 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003805
Facundo Batistaeb90b782008-08-16 14:44:07 +00003806- Issue #2776: fixed small issue when handling an URL with double slash
3807 after a 302 response in the case of not going through a proxy.
3808
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003809- Issue #2676: in the email package, content-type parsing was hanging on
3810 pathological input because of quadratic or exponential behaviour of a
3811 regular expression.
3812
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003813- Issue #3476: binary buffered reading through the new "io" library is now
3814 thread-safe.
3815
Brett Cannonbf3157b2008-08-14 05:00:03 +00003816- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3817 since mimetools itself is deprecated. Because modules are cached, all
3818 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3819
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003820- Issue #3134: shutil referenced undefined WindowsError symbol.
3821
Robert Schuppenies14646332008-08-10 11:01:53 +00003822- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3823 menu entries were not deleted.
3824
Brett Cannon83e81842008-08-09 23:30:55 +00003825- Copied the implementation of reduce() to _functools.reduce() to have a
3826 version that did not raise a DeprecationWarning under -3.
3827
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003828- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3829 a MemoryError rather than silently stop the iteration.
3830
Guido van Rossum59ce9012008-08-09 14:55:34 +00003831- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3832 to _sre.compile() will now be rejected. This should not affect anybody
3833 since the re.compile() function never generates invalid re-bytecode.
3834
Skip Montanaroa032bf42008-08-08 22:52:51 +00003835- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3836 upon first access it can be automatically initialized from the csv file if
3837 it wasn't initialized during instantiation.
3838
Brett Cannon3aa2a492008-08-06 22:28:09 +00003839- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3840 the reload() built-in has been removed.
3841
Brett Cannon7e30b672008-08-04 21:52:25 +00003842- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003843 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3851 raised an AttributeError.
3852
Benjamin Peterson01a24322008-07-28 23:35:27 +00003853- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003854 asking for a specific length. This problem only affected files opened
3855 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003856
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003857- Issue #3449: Update decimal module to use most recent specification
3858 (v. 1.68) and tests (v. 2.58) from IBM.
3859
Georg Brandl222e2082010-08-01 22:27:39 +00003860- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00003861

3868
3869- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3870 invalid arguments.
3871
3872- Issue #3302: Fix several crashes when calling locale's gettext functions
3873 with None arguments.
3874
3875- Issue #3389: Allow resolving dotted names for handlers in logging
3876 configuration files.
3877
3878- Deprecate the sunaudio module for removal in Python 3.0.
3879
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003880- Issue #3394: zipfile.writestr sets external attributes when passed a
3881 file name rather than a ZipInfo instance, so files are extracted with
3882 mode 0600 rather than 000 under Unix.
3883
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003884- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3885 argument in python 2.5, this broke code that subclassed Popen to include its
3886 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00003896- Issue #2235: the C API function PyObject_HashNotImplemented and its
3897 interaction with the tp_hash slot (added in 2.6b2) are now documented
3898
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003899- Issue #643841: The language reference now provides more detailed
3900 coverage of the lookup process for special methods. The disclaimers
3901 regarding lack of coverage of new-style classes have also been
3902 removed, since the coverage is now fairly reasonable.

3911-----------------
3912
Georg Brandl3e483f62008-07-16 22:57:41 +00003913- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3914 its methods now allow for items objects that can be converted to
3915 an integer using operator.index().
3916
Mark Dickinson64b7e502008-07-16 09:40:03 +00003917- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3918 produced a ValueError instead of giving the correct float.
3919
Eric Smitha5fa5a22008-07-16 00:11:49 +00003920- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3921 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3922
Mark Dickinson7103aa42008-07-15 19:08:33 +00003923- Issue #3008: the float type has a new instance method 'float.hex'
3924 and a new class method 'float.fromhex' to convert floating-point
3925 numbers to and from hexadecimal strings, respectively.
3926
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003927- Issue #2235: __hash__ is once again inherited by default. To allow
3928 collections.Hashable to remain meaningful in the presence of the
3929 default hash implementation (object.__hash__), it is now possible
3930 to explicit block inheritance of hash by setting __hash__=None at
3931 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3932 level.
3933
Nick Coghlanb028f502008-07-13 14:52:36 +00003934- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3935 the parent module cannot be found while performing an absolute import.
3936 This means that an incorrectly defined __package__ attribute will
3937 now only prevent relative imports in that module rather than causing
3938 all imports from that module to fail.
3939
Nick Coghlan14ff9942008-07-08 14:21:42 +00003940- Issue #2517: Allow unicode messages in Exceptions again by correctly
3941 bypassing the instance dictionary when looking up __unicode__ on
3942 new-style classes.

3950 another thread's dictionary.
3951
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003952- Issue #3004: Minor change to slice.indices(): the start and stop
3953 arguments are now treated identically, making the behaviour easier
3954 to describe and understand. For example, slice(None, -10,
3955 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3956 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3957 10, -1).
3958
Georg Brandl278fc502008-07-19 12:46:12 +00003959- Issue #3219: Calling a function with repeated keyword arguments,

3961 from 2.4 caused by the switch to the new compiler.

4410 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004411 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004412
4413 This is controlled by the configure argument ``--with-universal-archs``:
4414
4415 - ``--with-universal-archs=all``: install 4-way universal
4416
4417 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4418
4419 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4420
4421 This option should be used in combination with ``--enable-universalsdk=``.
4422
4423 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

4460 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00004461
Christian Heimese74c8f22008-04-19 02:23:57 +00004462- Added kill, terminate and send_signal(sig) to subprocess.Popen.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004473- Issue #1631171: Re-implement the 'warnings' module in C (the
4474 original Python code has been kept as backup). This will allow for
4475 using the 'warning's machinery in such places as the parser where
4476 use of pure Python code is not possible. Both the ``showarning()``
4477 and ``formatwarning()`` gain an optional 'line' argument which is
4478 not called by default for backwards-compatibility reasons. Setting
4479 ``warnings.showwarning()`` to an implementation that lacks support
4480 for the ``line`` argument will raise a DeprecationWarning.

4504
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004505- The getpass module has been improved on Unix. It now uses /dev/tty
4506 by default and uses stderr instead of stdout. A GetPassWarning is
4507 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004522- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004523 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004535- Issue #2385: distutils.core.run_script() makes __file__ available,
4536 so the controlled environment will more closely mirror the typical
4537 script environment. This supports setup.py scripts that refer to
4538 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004543- Issue #2550: The approach used by client/server code for obtaining
4544 ports to listen on in network-oriented tests has been refined in an
4545 effort to facilitate running multiple instances of the entire
4546 regression test suite in parallel without issue.
4547 test_support.bind_port() has been fixed such that it will always
4548 return a unique port -- which wasn't always the case with the
4549 previous implementation, especially if socket options had been set
4550 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4551 new implementation of bind_port() will actually raise an exception
4552 if it is passed an AF_INET/SOCK_STREAM socket with either the
4553 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4554 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4555 the socket it's been passed. This currently only applies to
4556 Windows. This option prevents any other sockets from binding to the
4557 host/port we've bound to, thus removing the possibility of the
4558 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4559 when a second SOCK_STREAM socket binds and accepts to a host/port
4560 that's already been bound by another socket. The optional preferred
4561 port parameter to bind_port() has been removed. Under no
4562 circumstances should tests be hard coding ports!
4563
4564 test_support.find_unused_port() has also been introduced, which will
4565 pass a temporary socket object to bind_port() in order to obtain an
4566 unused port. The temporary socket object is then closed and
4567 deleted, and the port is returned. This method should only be used
4568 for obtaining an unused port in order to pass to an external program
4569 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4570 a parameter to a server-oriented class that doesn't give you direct
4571 access to the underlying socket used.
4572
4573 Finally, test_support.HOST has been introduced, which should be used
4574 for the host argument of any relevant socket calls (i.e. bind and
4575 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004576
4577 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004578 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004579 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4580 test_asynchat and test_socket_ssl.
4581
Georg Brandl3ee81df2008-05-17 18:14:43 +00004582 It is now possible for multiple instances of the regression test
4583 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00004862- Added the future_builtins module, which contains hex() and oct().
4863 These are the PEP 3127 version of these functions, designed to be
4864 compatible with the hex() and oct() builtins from Python 3.0. They
4865 differ slightly in their output formats from the existing, unchanged
4866 Python 2.6 builtins. The expected usage of the future_builtins
4867 module is:
4868 from future_builtins import hex, oct
4869
Eric Smith7ef40bf2008-02-20 23:34:22 +00004870- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4871 exponents for exponents with absolute value < 100. Follows C99
4872 standard. This is a change on Windows, which would use 3 digits.
4873 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4874 so that any alterations it does to the resulting string will be
4875 available in stringlib/formatter.h (for float.__format__).
4876
Eric Smith5a3c1352008-02-19 13:21:56 +00004877- Implemented PEP 3101, Advanced String Formatting. This adds a new
4878 builtin format(); a format() method for str and unicode; a
4879 __format__() method to object, str, unicode, int, long, float, and
4880 datetime; the class string.Formatter; and the C API
4881 PyObject_Format().
4882
Georg Brandl3ee81df2008-05-17 18:14:43 +00004883- Fixed several potential crashes, all caused by specially crafted
4884 __del__ methods exploiting objects in temporarily inconsistent
4885 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004886
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004887- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004888 prevent a possible crash: an Abstract Base Class would try to access
4889 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004890

Georg Brandl3ee81df2008-05-17 18:14:43 +00004894- Clear all free lists during a gc.collect() of the highest generation
4895 in order to allow pymalloc to free more arenas. Python may give back
4896 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004897
Georg Brandl3ee81df2008-05-17 18:14:43 +00004898- Issue #2045: Fix an infinite recursion triggered when printing a
4899 subclass of collections.defaultdict, if its default_factory is set
4900 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004901
Christian Heimesf75dbef2008-02-08 00:11:31 +00004902- Fixed a minor memory leak in dictobject.c. The content of the free
4903 list was not freed on interpreter shutdown.
4904
Georg Brandl21e99f42010-03-07 15:23:59 +00004905- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004906 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004907
Georg Brandl3ee81df2008-05-17 18:14:43 +00004908- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4909 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004910 to compact the internal free lists of pre-allocted ints and floats.
4911
Georg Brandl3ee81df2008-05-17 18:14:43 +00004912- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4913 calls. Python expected the return type int but the fork familie
4914 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004915
Georg Brandl3ee81df2008-05-17 18:14:43 +00004916- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00004928- Patch #1473257: generator objects gain a gi_code attribute. This is
4929 the same object as the func_code attribute of the function that
4930 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004931
Georg Brandl3ee81df2008-05-17 18:14:43 +00004932- Issue #1920: "while 0" statements were completely removed by the
4933 compiler, even in the presence of an "else" clause, which is
4934 supposed to be run when the condition is false. Now the compiler
4935 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004936
Guido van Rossumeead05f2008-01-24 18:21:02 +00004937- A few crashers fixed: weakref_in_del.py (issue #1377858);
4938 loosing_dict_ref.py (issue #1303614, test67.py);
4939 borrowed_ref_[34].py (not in tracker).
4940
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004941- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004942 suppressed while an extension is loaded by calling SetErrorMode in
4943 dynload_win.c. The error is still reported properly.
4944
Georg Brandl3ee81df2008-05-17 18:14:43 +00004945- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004946 several extension methods and modules do not work without unicode
4947 support.
4948
Georg Brandl26543b12008-01-21 18:36:51 +00004949- Issue #1882: when compiling code from a string, encoding cookies in the
4950 second line of code were not always recognized correctly.
4951
Georg Brandl14404b62008-01-19 19:27:05 +00004952- Issue #1679: "0x" was taken as a valid integer literal.
4953
Georg Brandl6caad7d2008-01-26 14:19:22 +00004954- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004955 added.
4956
Christian Heimesc94e2b52008-01-14 04:13:37 +00004957- sys.float_info / PyFloat_GetInfo: The floating point information
4958 object was converted from a dict to a specialized structseq object.
4959
Georg Brandl3ee81df2008-05-17 18:14:43 +00004960- Patch #1816: Added sys.flags structseq. It exposes the status of
4961 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004962
Georg Brandl3ee81df2008-05-17 18:14:43 +00004963- Objects/structseq.c: Implemented new structseq representation. The

4965 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004966
Georg Brandl3ee81df2008-05-17 18:14:43 +00004967- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00004989 and INF. float("nan"), float("inf") and float("-inf") now work on
4990 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004991
Georg Brandl3ee81df2008-05-17 18:14:43 +00004992- Compiler now generates simpler and faster code for dictionary
4993 literals. The oparg for BUILD_MAP now indicates an estimated
4994 dictionary size. There is a new opcode, STORE_MAP, for adding
4995 entries to the dictionary.

Georg Brandl21e99f42010-03-07 15:23:59 +00005039- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005040 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5041 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005042
Georg Brandl3ee81df2008-05-17 18:14:43 +00005043- Issue #1686386: Tuple's tp_repr did not take into account the
5044 possibility of having a self-referential tuple, which is possible
5045 from C code. Nor did object's tp_str consider that a type's tp_str
5046 could do something that could lead to an inifinite recursion.
5047 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5048 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005049
Georg Brandl3ee81df2008-05-17 18:14:43 +00005050- Issue #1164: It was possible to trigger deadlock when using the
5051 'print' statement to write to a file since the GIL was not released
5052 as needed. Now PyObject_Print() does the right thing along with
5053 various tp_print implementations of the built-in types and those in
5054 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005055
Georg Brandl3ee81df2008-05-17 18:14:43 +00005056- Issue #1147: Exceptions were directly allowing string exceptions in
5057 their throw() method even though string exceptions no longer
5058 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005059
Georg Brandl3ee81df2008-05-17 18:14:43 +00005060- Issue #1096: Prevent a segfault from getting the repr of a very
5061 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005062
Brett Cannon1e534b52007-09-07 04:18:30 +00005063- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005064 PyObject_Call() never calling back out to Python code to trigger
5065 recursion depth updates/checks. Required the creation of a static
5066 RuntimeError instance in case normalizing an exception put the
5067 recursion check value past its limit. Fixes crashers
5068 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005069

Neal Norwitz0ac60192007-05-27 04:08:54 +00005083- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005084 __*__ attributes. (Some already existed, e.g., __doc__ and
5085 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005086
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005087- Add -3 option to the interpreter to warn about features that are
5088 deprecated and will be changed/removed in Python 3.0.
5089
Georg Brandl2134e752007-05-21 20:34:16 +00005090- Patch #1686487: you can now pass any mapping after '**' in function
5091 calls.
5092
Collin Winter62903052007-05-18 23:11:24 +00005093- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005094 "except E as target:". This is to provide forwards compatibility
5095 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005096
Brett Cannon229cee22007-05-05 01:34:02 +00005097- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005102- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005103 setting a plain string, ie don't expand to single letter identifiers.
5104
Raymond Hettinger13936692007-04-11 18:40:58 +00005105- Request #1191699: Slices can now be pickled.
5106
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005107- Request #1193128: str.translate() now allows a None argument for
5108 translations that only remove characters without re-mapping the
5109 remaining characters.
5110
Georg Brandl5cb76c12007-03-21 09:00:39 +00005111- Patch #1682205: a TypeError while unpacking an iterable is no longer

5115
Guido van Rossum143b5642007-03-23 04:58:42 +00005116- Bug #1683368: The object.__init__() and object.__new__() methods are
5117 now stricter in rejecting excess arguments. The only time when
5118 either allows excess arguments is when it is not overridden and the
5119 other one is. For backwards compatibility, when both are
5120 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005121 warning later). Also, type.__init__() insists on the same signature
5122 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005123
Georg Brandl3ee81df2008-05-17 18:14:43 +00005124- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5125 object to complex using its __complex__() method before falling back
5126 to the __float__() method. Therefore, the functions in the cmath
5127 module now can operate on objects that define a __complex__()
5128 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005129
Georg Brandl3ee81df2008-05-17 18:14:43 +00005130- Patch #1623563: allow __class__ assignment for classes with

5139 its type.

5145
Georg Brandl7b9c5552007-03-12 14:30:05 +00005146- Bug #1678647: write a newline after printing an exception in any
5147 case, even when converting the value to a string failed.
5148
Georg Brandl871f1bc2007-03-12 13:17:36 +00005149- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005150 its argument, if it exists. If not, it will work like before. This
5151 allows customizing the output of dir() in the presence of a
5152 __getattr__().

5161 parthensized forms. This means complex(repr(x)) now works instead of
5162 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005163
Georg Brandlaa2321b2007-03-07 00:40:28 +00005164- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005165 makes the filenames the warning module prints much more sensible
5166 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005167

Georg Brandl0fca97a2007-03-05 22:28:08 +00005179- Patch #1674228: when assigning a slice (old-style), check for the
5180 sq_ass_slice instead of the sq_slice slot.
5181
Georg Brandl3ee81df2008-05-17 18:14:43 +00005182- When printing an unraisable error, don't print exceptions. before
5183 the name. This duplicates the behavior whening normally printing
5184 exceptions.

5813 exception.

6026 partial fix for Bug #1574584.
6027
Georg Brandl3ee81df2008-05-17 18:14:43 +00006028- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006094- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6095 with RFC 3207 and forgets any knowledge obtained from the server not
6096 obtained from the TLS negotiation itself. Patch contributed by Bill
6097 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006098
Georg Brandl3ee81df2008-05-17 18:14:43 +00006099- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006100 that the SMTP.starttls() caller no longer needs to call ehlo()
6101 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006102 does not claim to support starttls. Adds the
6103 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
6104 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006158- itertools.chain() now has an alternate constructor,

6184 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6185 silently miscode subclasses of those types. Now, it raises a
6186 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006187

Georg Brandl3ee81df2008-05-17 18:14:43 +00006202 time so that opening a database previously created with the DB_DUP
6203 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6204 opens. Specifically: dictionary assignment to a DB object will
6205 replace all values for a given key when the database allows
6206 duplicate values. DB users should use DB.put(k, v) when they want
6207 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006208

6214 characters with ASCII value less than 32. Also, it correctly quotes
6215 dots only if they occur on a single line, as opposed to the previous
6216 behavior of quoting dots if they are the second character of any
6217 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006218

6540-----
6541
Georg Brandl3ee81df2008-05-17 18:14:43 +00006542- Unified naming convention for free lists and their limits. All free
6543 lists in Object/ are named ``free_list``, the counter ``numfree``
6544 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
6545 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00006546
Georg Brandl3ee81df2008-05-17 18:14:43 +00006547- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6548 to ``PyTuple_SetItem``, it can be used to populate a brand new
6549 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00006550
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006551- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

6554 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
6555 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006556
6557- Patch #1720595: add T_BOOL to the range of structmember types.
6558
6559- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
6560 ``PyFloat_GetInfo()`` to the float API.
6561
Georg Brandl3ee81df2008-05-17 18:14:43 +00006562- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6563 of w# format code incorrectly truncated the length to an int, even
6564 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6565 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006566
Georg Brandl3ee81df2008-05-17 18:14:43 +00006567- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
6568 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006570- PEP 3123: Provide forward compatibility with Python 3.0, while
6571 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
6572 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006573
Georg Brandl3ee81df2008-05-17 18:14:43 +00006574- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
6575 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006576
6577- Patch #1733960: Allow T_LONGLONG to accept ints.

6584
6585- Fix some leftovers from the conversion from int to Py_ssize_t
6586 (relevant to strings and sequences of more than 2**31 items).
6587
6588- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6589 outside of pystate.c and should not be necessary.
6590
Georg Brandl3ee81df2008-05-17 18:14:43 +00006591- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6592 absolute imports. In earlier versions they might have used relative
6593 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006594
Georg Brandl3ee81df2008-05-17 18:14:43 +00006595- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6596 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006597
Georg Brandl3ee81df2008-05-17 18:14:43 +00006598- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
6599 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006605- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
6606 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6607 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6608 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00006609

Georg Brandl3ee81df2008-05-17 18:14:43 +00006623- Removed the macfs module. It had been deprecated since Python 2.5.
6624 This lead to the deprecation of macostools.touched() as it relied
6625 solely on macfs and was a no-op under OS X.
