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

60 gname field.
61
R. David Murray10a86762010-10-02 16:26:05 +000062- Issue #1050268: parseaddr now correctly quotes double quote and backslash
63 characters that appear inside quoted strings in email addresses.
64
R. David Murray20ad3632010-10-01 15:48:49 +000065- Issue #10004: quoprimime no longer generates a traceback when confronted
66 with invalid characters after '=' in a Q-encoded word.

Antoine Pitrou66b5df62010-09-27 18:16:46 +000068- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
69 received. Now sendall() properly calls signal handlers if necessary,

78
Antoine Pitrou2c7d6852010-09-23 19:55:24 +000079- Issue #9928: Properly initialize the types exported by the bz2 module.
80
Antoine Pitrou6391b342010-09-14 18:48:19 +000081- Issue #9854: The default read() implementation in io.RawIOBase now
82 handles non-blocking readinto() returning None correctly.
83
Antoine Pitrouf7f390a2010-09-14 14:37:18 +000084- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
85 SSLSocket.sendto() to match the corresponding socket methods. Also,
86 fix various SSLSocket methods to raise socket.error rather than an
87 unhelpful TypeError when called on an unconnected socket. Original patch
88 by Andrew Bennetts.
89
Raymond Hettinger74f869e2010-09-13 22:14:36 +000090- Issue #9826: OrderedDict.__repr__ can now handle self-referential
91 values: d['x'] = d.

96 ZipFile.open()) could return more bytes than requested.
97
Raymond Hettinger20397532010-09-12 02:11:45 +000098- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
99 This prevents user-created self-referencing ordered dictionaries from
100 becoming permanently uncollectable GC garbage. The downside is that
101 removing __del__ means that the internal doubly-linked list has to wait for
102 GC collection rather than freeing memory immediately when the refcnt drops
103 to zero.
104
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000105- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
106 different internal state for small values of n. Fixed by salting the
107 value.
108
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000109- Issue #9792: In case of connection failure, socket.create_connection()
110 would swallow the exception and raise a new one, making it impossible
111 to fetch the original errno, or to filter timeout errors. Now the
112 original error is re-raised.
113
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000114- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
115 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
116 be updated back after the system call. Original patch by Brian Brazil.
117
Antoine Pitroudca9de92010-09-04 17:52:26 +0000118- Issue #1100562: Fix deep-copying of objects derived from the list and
119 dict types. Patch by Michele Orrù and Björn Lindqvist.
120
Fred Drakea1e627d2010-09-03 03:55:50 +0000121- Issue #7005: Fixed output of None values for RawConfigParser.write and
122 ConfigParser.write.
123
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000124- Issue #808164: Fixed socket.close to avoid references to globals, to
125 avoid issues when socket.close is called from a __del__ method.
126
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +0000127- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
128 falling into recursion.
129
R. David Murray7c4bf552010-08-25 01:45:57 +0000130- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
131 character years even if the message contains RFC822 two character years.
132
Daniel Stutzbach91287322010-08-24 21:09:30 +0000133- Issue #8750: Fixed MutableSet's methods to correctly handle
134 reflexive operations, namely x -= x and x ^= x.
135
Victor Stinnercaafd772010-09-08 10:51:01 +0000136- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing
Giampaolo Rodolà8664d742010-08-23 22:48:51 +0000137 error handling when accepting a new connection.
138
Giampaolo Rodolà63308d72010-08-23 21:58:47 +0000139- Issue #658749: asyncore's connect() method now correctly interprets winsock
140 errors.

146
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000147- Issue #9617: Signals received during a low-level write operation aren't
148 ignored by the buffered IO layer anymore.
149
Benjamin Peterson52c36052010-08-21 03:03:22 +0000150- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
151 are not held onto after they are deleted elsewhere.
152
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000153- Issue #9626: the view methods for collections.OrderedDict() were returning
154 the unordered versions inherited from dict. Those methods are now
155 overridden to provide ordered views.
156
Éric Araujo0389ae62010-08-14 03:07:46 +0000157- Issue #8688: MANIFEST files created by distutils now include a magic
158 comment indicating they are generated. Manually maintained MANIFESTs
159 without this marker will not be overwritten or removed.
160
Antoine Pitroue1436d12010-08-12 15:25:51 +0000161- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
162 and a BadZipfile error is raised if it doesn't match (as used to be the

164
Antoine Pitroucb4f47c2010-08-11 13:40:17 +0000165- Issue #9550: a BufferedReader could issue an additional read when the
166 original read request had been satisfied, which could block indefinitely
167 when the underlying raw IO channel was e.g. a socket. Report and original
168 patch by Jason V. Miller.
169
Fred Drake0a1fa0e2010-08-10 13:09:54 +0000170- Issue #9551: Don't raise TypeError when setting the value to None for

175
Antoine Pitrou99009162010-08-09 22:51:24 +0000176- Issue #3757: thread-local objects now support cyclic garbage collection.
177 Thread-local objects involved in reference cycles will be deallocated
178 timely by the cyclic GC, even if the underlying thread is still running.
179

190 behavior was wrong.
191

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000909 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
910 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
911 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

931Core and Builtins
932-----------------
933
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000934- Issue #7301: Add environment variable $PYTHONWARNINGS.
935
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000936- Issue #8329: Don't return the same lists from select.select when no fds are
937 changed.
938
Georg Brandlfee0f442010-05-22 21:26:21 +0000939- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000940 on 64-bit machines. The shift count for either left or right shift is
941 permitted to be up to sys.maxsize.
942
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000943- Ensure that tokenization of identifiers is not affected by locale.
944
Georg Brandlfee0f442010-05-22 21:26:21 +0000945- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000947- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
948
Georg Brandlfee0f442010-05-22 21:26:21 +0000949- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
950 with a non-empty format string. This is an effort to future-proof user
951 code. If a derived class does not currently implement __format__ but later
952 adds its own __format__, it would most likely break user code that had
953 supplied a format string. This will be changed to a DeprecationWaring in
954 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000955
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000956- Issue #8268: Old-style classes (not just instances) now support weak

980
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000981- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000982 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and

986
Georg Brandlfee0f442010-05-22 21:26:21 +0000987- Issue #8257: The Decimal construct now accepts a float instance directly,
988 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000989
990 >>> Decimal(1.1)
991 Decimal('1.100000000000000088817841970012523233890533447265625')
992
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000993- collections.Counter() now supports a subtract() method.
994
Georg Brandlfee0f442010-05-22 21:26:21 +0000995- The functools module now has a total_ordering() class decorator to simplify
996 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000997
Georg Brandlfee0f442010-05-22 21:26:21 +0000998- The functools module also adds cmp_to_key() as a tool to transition old-style
999 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001000
Georg Brandlfee0f442010-05-22 21:26:21 +00001001- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1002 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00001003
Georg Brandlfee0f442010-05-22 21:26:21 +00001004- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1005 InvalidOperation instead of returning False. (Comparisons involving a quiet
1006 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1007 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001008
Georg Brandlfee0f442010-05-22 21:26:21 +00001009- Issue #2531: Comparison operations between floats and Decimal instances now
1010 return a result based on the numeric values of the operands; previously they
1011 returned an arbitrary result based on the relative ordering of id(float) and
1012 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001013
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001014- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001015 argument `-` which tells it to read files to compile from stdin. Each line is
1016 read on demand and the named file is compiled immediately. (Original patch by
1017 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001018
Georg Brandlfee0f442010-05-22 21:26:21 +00001019- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00001022- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1023 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001024 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001025
Georg Brandlfee0f442010-05-22 21:26:21 +00001026- Comparisons using one of <, <=, >, >= between a complex instance and a
1027 Fractions instance now raise TypeError instead of returning True/False. This
1028 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1029 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001030

1039
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001040- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001041 didn't support chflags() (for example ZFS under FreeBSD). The error is now
1042 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001043
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00001044- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
1045 deprecated.
1046
Georg Brandlfee0f442010-05-22 21:26:21 +00001047- Issue #7860: platform.uname now reports the correct 'machine' type when Python

Vinay Sajipecfa08f2010-03-12 09:16:10 +00001084- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001085 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1086 log file to compute the next rollover time. If the log file does not exist,
1087 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00001088

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001128- Issue #8300: When passing a non-integer argument to struct.pack with any
1129 integer format code, struct.pack first attempts to convert the non-integer
1130 using its __index__ method. If that method is non-existent or raises
1131 TypeError it goes on to try the __int__ method, as described below.
1132
Georg Brandlba83f822010-03-14 09:50:54 +00001133- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1134 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1135 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001136 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1137 inconsistent: __int__ was used for some integer codes but not for others, and
1138 the set of integer codes for which it was used differed between native packing
1139 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00001347- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
1348 now also used by regrtest to run all the tests in a temporary directory. The
1349 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
1350 Xicluna who helped with the patch.

1367 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00001368 library would return a bogus result; on Solaris, it was possible to crash the
1369 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +00001387- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
1388 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1389 returning NULL. The macro now returns a statically allocated empty string
1390 instead.

1400 strings,
1401 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
1402 numeric strings corresponding to subnormal values,
1403 (3) a memory leak for some values large enough to cause overflow, and
1404 (4) a number of flaws that could lead to incorrectly rounded results.

1423
Georg Brandlba83f822010-03-14 09:50:54 +00001424- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in

Antoine Pitroud840e512010-02-04 20:20:18 +00001435- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00001436 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00001437 Also, raise ValueError rather than TypeError when an unknown TIPC address
1438 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001442- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001443 file position when calling `truncate()`. It would previously change the file
1444 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001445 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1446
Georg Brandlba83f822010-03-14 09:50:54 +00001447- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1448 class used to represent files stored inside an archive. The new
1449 implementation is significantly faster and can be wrapped in a
1450 ``io.BufferedReader`` object for more speedups. It also solves an issue
1451 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
1452 Patch by Nir Aides.
Antoine Pitrou94c33eb2010-01-27 20:59:50 +00001453
Benjamin Peterson2deb5c72010-01-27 02:16:42 +00001454- Issue #7792: Registering non-classes to ABCs raised an obscure error.

Benjamin Petersona43f34c2010-01-25 03:31:13 +00001461
Georg Brandlba83f822010-03-14 09:50:54 +00001462- Issue #7748: Since unicode values are supported for some metadata options in
1463 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1464 encoded string for them. This ensures that the upload and register commands
1465 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00001542- The ``__complex__()`` method is now looked up on the class of instances to
1543 make it consistent with other special methods.

1547
Mark Dickinson1b34d252010-01-01 17:27:30 +00001548- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001549 DeprecationWarning when passed a float argument where an integer was expected.
1550 These functions and methods now raise TypeError instead. The majority of the
1551 effects of this change are in the extension modules, but some core functions
1552 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1553 and many unicode/str methods.

1567 of integers: the result of a/b is now correctly rounded for ints a and b (at
1568 least on IEEE 754 platforms), and in particular does not depend on the
1569 internal representation of a long.

1577
Georg Brandlba83f822010-03-14 09:50:54 +00001578 These executables now work properly with the arch(1) command: ``arch -ppc
1579 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00001736- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1737 decimal string that's guaranteed to round back to x under correct rounding
1738 (with round-half-to-even rounding mode). Previously it gave a string based on
1739 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1740 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1741 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001742
Georg Brandlba83f822010-03-14 09:50:54 +00001743- Issue #7117: On almost all platforms: float-to-string and string-to-float
1744 conversions within Python are now correctly rounded. Places these conversions
1745 occur include: str for floats and complex numbers; the float and complex
1746 constructors; old-style and new-style numeric formatting; serialization and
1747 deserialization of floats and complex numbers using marshal, pickle and json;
1748 parsing of float and imaginary literals in Python code; Decimal-to-float
1749 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001750
Georg Brandlba83f822010-03-14 09:50:54 +00001751 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1752 providing correctly-rounded strtod and dtoa C functions. This code is
1753 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1754 the C compiler. There may be a small number of platforms on which correct
1755 operation of this code cannot be guaranteed, so the code is not used: notably,
1756 this applies to platforms where the C double format is not IEEE 754 binary64,
1757 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1758 and Python's configure script is unable to determine how to change the FPU
1759 precision. On these platforms conversions use the platform strtod and dtoa,
1760 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001761
Georg Brandlba83f822010-03-14 09:50:54 +00001762- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1763 uses the correctly-rounded string <-> float conversions described above (when
1764 available), and so produces correctly rounded results that will display nicely
1765 under the float repr. There are two related small changes: (1) round now
1766 accepts any class with an ``__index__()`` method for its second argument (but
1767 no longer accepts floats for the second argument), and (2) an excessively
1768 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1769 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001916- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1917 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1918 but with at least one decimal point and with a default precision
1919 of 12. Previously, the behavior the same but with a default precision of 6.
1920 This more closely matches ``str()``, and reduces surprises when adding
1921 alignment flags to the empty presentation type. This also affects the new
1922 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00002062- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2063 existing .py counterpart, override the co_filename attributes of all code

2119
Georg Brandlba83f822010-03-14 09:50:54 +00002120- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2121 file objects with closefd=False. The file descriptor is still kept open but
2122 the file object behaves like a closed file. The ``FileIO`` object also got a

2142
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002143- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00002146- On windows, ``os.chdir()`` given unicode was not working if
2147 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2148 this code path is really executed because I cannot move to such directory on
2149 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002151- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2152 element is temporarily replaced with an equivalent frozenset. But the
2153 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00002174- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2175 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2176 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2177 of using the replace error handler in PyUnicode_DecodeUTF8().
2178
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002179- Issue #3739: The unicode-internal encoder now reports the number of characters

2181
Georg Brandlba83f822010-03-14 09:50:54 +00002182- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

2184 gives improved memory leak detection when running under Valgrind, while taking
2185 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00003408 leak-chasing test runs give sensible results. The previous method of reaping
3409 threads could return successfully while some Thread objects were still
3410 referenced. This also introduces a new private function: ``thread._count()``.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00003427- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
3428 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00003429 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
3430 the tests if DISPLAY is defined but can't be used.

3436 import both normal and optimised versions of modules. test_heapq and
3437 test_warnings have been adjusted to use it, tests for other modules with both
3438 C and Python implementations in the stdlib can be adjusted to use it over
3439 time.

3551
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003552- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3553 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3554 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3555 ``printf`` function, whereas PyString_FromFormat has an independent
3556 implementation and uses "%zd" on all platforms for size_t values.
3557 This makes a difference on win64, where ``printf`` needs "%Id" to display
3558 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00003560- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3564 object; previously an int would be returned for small values. the __long__
3565 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003575 was correctly parsed but parsing of subsequent arguments failed.

Vinay Sajip35e3b032008-09-01 14:33:59 +00003577- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003578 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3579 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3580 when given a tuple of classes as second argument, were looking up
3581 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3582 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003721What's New in Python 2.6 beta 3?
3722================================
3723
Barry Warsaw07a4a382008-08-21 01:15:08 +00003724*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003725
3726Core and Builtins
3727-----------------
3728
Guido van Rossumf8402962008-08-20 15:01:50 +00003729- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3730 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3731 extensions do not automatically benefit from the class attribute
3732 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3733 to their tp_flags field if they care. This is a backwards
3734 compatibility feature; in 3.0, all types will use the cache by
3735 default.
3736
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003737- Keyword arguments can now follow starred arguments. (``f(a, *args,
3738 keyword=23)`` is now valid syntax.)
3739
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003740- ctypes function pointers that are COM methods have a boolean True
3741 value again.
3742
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003743- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3744 by denying s# to parse objects that have a releasebuffer procedure,
3745 and introducing s*.
3746
Georg Brandl1e13ea92008-08-11 09:07:59 +00003747- Issue #3537: Fix an assertion failure when an empty but presized dict
3748 object was stored in the freelist.
3749
Mark Dickinsonb6467572008-08-04 21:30:09 +00003750- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3751 ValueError consistently across platforms.
3752
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003753- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3754 (64bit Unix, for example), unichr() would truncate its argument and return
3755 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3756
Neal Norwitze7d8be82008-07-31 17:17:14 +00003757- Apply security patches from Apple.
3758
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003759- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3760 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3761
Antoine Pitrou92f82162008-07-25 22:22:08 +00003762- Issue #1819: function calls with several named parameters are now on
3763 average 35% faster (as measured by pybench).
3764
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003765- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3766 the python debugger steps into a class statement: the free variables (local
3767 variables defined in an outer scope) would be deleted from the outer scope.
3768
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003769- Issue #2620: Overflow checking when allocating or reallocating memory
3770 was not always being done properly in some python types and extension
3771 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3772 all been updated to perform better checks and places in the code that
3773 would previously leak memory on the error path when such an allocation
3774 failed have been fixed.

3777-------
3778
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003779- Issue #3612: Added some missing basic types in ctypes.wintypes.
3780
Benjamin Petersone977ad42008-08-20 01:42:01 +00003781- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3782 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3783
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003784- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3785 version reported by these tools does not necessarily follow the python
3786 version numbering scheme, so the module is less strict when parsing it.
3787
Nick Coghlanf70385a2008-08-18 12:42:46 +00003788- Issue #2235: Added Py3k warnings for types which will become unhashable
3789 under the stricter __hash__ inheritance rules in 3.0. Several types
3790 which did not meet the rules for hash invariants and were already
3791 unhashable in 3.0 have now been explicitly flagged as unhashable in
3792 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3793 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3794
Brett Cannon88f801d2008-08-18 00:46:22 +00003795- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3796 imported into the module but exposed as part of the module's API.
3797
Brett Cannon7b96f072008-08-18 00:41:11 +00003798- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3799
Brett Cannon46225e72008-08-18 00:36:52 +00003800- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
3801
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003802- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3803
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003804- Issue #3575: Incremental decoder's decode function now takes bytearray
3805 by using 's*' instead of 't#'.
3806
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003807- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003808 fails unicode conversion on 2nd parameter. (windows only)
3809
Georg Brandl222e2082010-08-01 22:27:39 +00003810- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003811 in a redirect.
3812
Brett Cannonabe423e2008-08-16 21:47:07 +00003813- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003814 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003815
Facundo Batistaeb90b782008-08-16 14:44:07 +00003816- Issue #2776: fixed small issue when handling an URL with double slash
3817 after a 302 response in the case of not going through a proxy.
3818
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003819- Issue #2676: in the email package, content-type parsing was hanging on
3820 pathological input because of quadratic or exponential behaviour of a
3821 regular expression.
3822
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003823- Issue #3476: binary buffered reading through the new "io" library is now
3824 thread-safe.
3825
Brett Cannonbf3157b2008-08-14 05:00:03 +00003826- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3827 since mimetools itself is deprecated. Because modules are cached, all
3828 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3829
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003830- Issue #3134: shutil referenced undefined WindowsError symbol.
3831
Robert Schuppenies14646332008-08-10 11:01:53 +00003832- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3833 menu entries were not deleted.
3834
Brett Cannon83e81842008-08-09 23:30:55 +00003835- Copied the implementation of reduce() to _functools.reduce() to have a
3836 version that did not raise a DeprecationWarning under -3.
3837
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003838- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3839 a MemoryError rather than silently stop the iteration.
3840
Guido van Rossum59ce9012008-08-09 14:55:34 +00003841- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3842 to _sre.compile() will now be rejected. This should not affect anybody
3843 since the re.compile() function never generates invalid re-bytecode.
3844
Skip Montanaroa032bf42008-08-08 22:52:51 +00003845- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3846 upon first access it can be automatically initialized from the csv file if
3847 it wasn't initialized during instantiation.
3848
Brett Cannon3aa2a492008-08-06 22:28:09 +00003849- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3850 the reload() built-in has been removed.
3851
Brett Cannon7e30b672008-08-04 21:52:25 +00003852- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003853 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Brett Cannon7e30b672008-08-04 21:52:25 +00003859
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00003860- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
3861 raised an AttributeError.
3862
Benjamin Peterson01a24322008-07-28 23:35:27 +00003863- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003864 asking for a specific length. This problem only affected files opened
3865 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003866
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003867- Issue #3449: Update decimal module to use most recent specification
3868 (v. 1.68) and tests (v. 2.58) from IBM.
3869
Georg Brandl222e2082010-08-01 22:27:39 +00003870- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00003871

3874
Georg Brandlf9efabb2008-07-23 15:16:45 +00003875- Deprecate the "ast" parser function aliases.
3876
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003877- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
3878
3879- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3880 invalid arguments.
3881
3882- Issue #3302: Fix several crashes when calling locale's gettext functions
3883 with None arguments.
3884
3885- Issue #3389: Allow resolving dotted names for handlers in logging
3886 configuration files.
3887

3889
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003890- Issue #3394: zipfile.writestr sets external attributes when passed a
3891 file name rather than a ZipInfo instance, so files are extracted with
3892 mode 0600 rather than 000 under Unix.
3893
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003894- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3895 argument in python 2.5, this broke code that subclassed Popen to include its
3896 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00003906- Issue #2235: the C API function PyObject_HashNotImplemented and its
3907 interaction with the tp_hash slot (added in 2.6b2) are now documented
3908
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003909- Issue #643841: The language reference now provides more detailed
3910 coverage of the lookup process for special methods. The disclaimers
3911 regarding lack of coverage of new-style classes have also been
3912 removed, since the coverage is now fairly reasonable.

3921-----------------
3922
Georg Brandl3e483f62008-07-16 22:57:41 +00003923- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3924 its methods now allow for items objects that can be converted to
3925 an integer using operator.index().
3926
Mark Dickinson64b7e502008-07-16 09:40:03 +00003927- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3928 produced a ValueError instead of giving the correct float.
3929
Eric Smitha5fa5a22008-07-16 00:11:49 +00003930- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3931 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3932
Mark Dickinson7103aa42008-07-15 19:08:33 +00003933- Issue #3008: the float type has a new instance method 'float.hex'
3934 and a new class method 'float.fromhex' to convert floating-point
3935 numbers to and from hexadecimal strings, respectively.
3936
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003937- Issue #2235: __hash__ is once again inherited by default. To allow
3938 collections.Hashable to remain meaningful in the presence of the
3939 default hash implementation (object.__hash__), it is now possible
3940 to explicit block inheritance of hash by setting __hash__=None at
3941 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3942 level.
3943
Nick Coghlanb028f502008-07-13 14:52:36 +00003944- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3945 the parent module cannot be found while performing an absolute import.
3946 This means that an incorrectly defined __package__ attribute will
3947 now only prevent relative imports in that module rather than causing
3948 all imports from that module to fail.
3949
Nick Coghlan14ff9942008-07-08 14:21:42 +00003950- Issue #2517: Allow unicode messages in Exceptions again by correctly
3951 bypassing the instance dictionary when looking up __unicode__ on
3952 new-style classes.
3953
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003954- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3955 set to a custom object whose write() method happens to install
3956 another file in sys.stdout.

3960 another thread's dictionary.
3961
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003962- Issue #3004: Minor change to slice.indices(): the start and stop
3963 arguments are now treated identically, making the behaviour easier
3964 to describe and understand. For example, slice(None, -10,
3965 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3966 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3967 10, -1).
3968
Georg Brandl278fc502008-07-19 12:46:12 +00003969- Issue #3219: Calling a function with repeated keyword arguments,
3970 f(a=2, a=23), would not cause a syntax error. This was a regression
3971 from 2.4 caused by the switch to the new compiler.

4420 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004421 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004422
4423 This is controlled by the configure argument ``--with-universal-archs``:
4424
4425 - ``--with-universal-archs=all``: install 4-way universal
4426
4427 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4428
4429 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4430
4431 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004483- Issue #1631171: Re-implement the 'warnings' module in C (the
4484 original Python code has been kept as backup). This will allow for
4485 using the 'warning's machinery in such places as the parser where
4486 use of pure Python code is not possible. Both the ``showarning()``
4487 and ``formatwarning()`` gain an optional 'line' argument which is
4488 not called by default for backwards-compatibility reasons. Setting
4489 ``warnings.showwarning()`` to an implementation that lacks support
4490 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004515- The getpass module has been improved on Unix. It now uses /dev/tty
4516 by default and uses stderr instead of stdout. A GetPassWarning is

Georg Brandl3ee81df2008-05-17 18:14:43 +00004545- Issue #2385: distutils.core.run_script() makes __file__ available,
4546 so the controlled environment will more closely mirror the typical
4547 script environment. This supports setup.py scripts that refer to
4548 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004553- Issue #2550: The approach used by client/server code for obtaining
4554 ports to listen on in network-oriented tests has been refined in an
4555 effort to facilitate running multiple instances of the entire
4556 regression test suite in parallel without issue.
4557 test_support.bind_port() has been fixed such that it will always
4558 return a unique port -- which wasn't always the case with the
4559 previous implementation, especially if socket options had been set
4560 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4561 new implementation of bind_port() will actually raise an exception
4562 if it is passed an AF_INET/SOCK_STREAM socket with either the
4563 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4564 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4565 the socket it's been passed. This currently only applies to
4566 Windows. This option prevents any other sockets from binding to the
4567 host/port we've bound to, thus removing the possibility of the
4568 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4569 when a second SOCK_STREAM socket binds and accepts to a host/port
4570 that's already been bound by another socket. The optional preferred
4571 port parameter to bind_port() has been removed. Under no
4572 circumstances should tests be hard coding ports!
4573
4574 test_support.find_unused_port() has also been introduced, which will
4575 pass a temporary socket object to bind_port() in order to obtain an
4576 unused port. The temporary socket object is then closed and
4577 deleted, and the port is returned. This method should only be used
4578 for obtaining an unused port in order to pass to an external program
4579 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4580 a parameter to a server-oriented class that doesn't give you direct
4581 access to the underlying socket used.
4582
4583 Finally, test_support.HOST has been introduced, which should be used
4584 for the host argument of any relevant socket calls (i.e. bind and
4585 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004586
4587 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004588 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004589 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4590 test_asynchat and test_socket_ssl.
4591
Georg Brandl3ee81df2008-05-17 18:14:43 +00004592 It is now possible for multiple instances of the regression test
4593 suite to run in parallel without issue.

Thomas Heller78b8f442008-03-05 14:53:39 +00004797- The bundled libffi copy is now in sync with the recently released
4798 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004799 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
4800 files are used. On all linux systems the --with-system-ffi
4801 configure option defaults to "yes".

Fred Drakea8ee94b2008-03-01 02:45:07 +00004862- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004863 644. The mode is now inherited from the py file.

Eric Smitha73fbe72008-02-23 03:09:44 +00004872- Added the future_builtins module, which contains hex() and oct().
4873 These are the PEP 3127 version of these functions, designed to be
4874 compatible with the hex() and oct() builtins from Python 3.0. They
4875 differ slightly in their output formats from the existing, unchanged
4876 Python 2.6 builtins. The expected usage of the future_builtins
4877 module is:
4878 from future_builtins import hex, oct
4879
Eric Smith7ef40bf2008-02-20 23:34:22 +00004880- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4881 exponents for exponents with absolute value < 100. Follows C99
4882 standard. This is a change on Windows, which would use 3 digits.
4883 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4884 so that any alterations it does to the resulting string will be
4885 available in stringlib/formatter.h (for float.__format__).
4886
Eric Smith5a3c1352008-02-19 13:21:56 +00004887- Implemented PEP 3101, Advanced String Formatting. This adds a new
4888 builtin format(); a format() method for str and unicode; a
4889 __format__() method to object, str, unicode, int, long, float, and
4890 datetime; the class string.Formatter; and the C API
4891 PyObject_Format().
4892
Georg Brandl3ee81df2008-05-17 18:14:43 +00004893- Fixed several potential crashes, all caused by specially crafted
4894 __del__ methods exploiting objects in temporarily inconsistent
4895 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004896
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004897- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004898 prevent a possible crash: an Abstract Base Class would try to access
4899 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004900

Georg Brandl3ee81df2008-05-17 18:14:43 +00004904- Clear all free lists during a gc.collect() of the highest generation
4905 in order to allow pymalloc to free more arenas. Python may give back
4906 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004907
Georg Brandl3ee81df2008-05-17 18:14:43 +00004908- Issue #2045: Fix an infinite recursion triggered when printing a
4909 subclass of collections.defaultdict, if its default_factory is set
4910 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004911
Christian Heimesf75dbef2008-02-08 00:11:31 +00004912- Fixed a minor memory leak in dictobject.c. The content of the free
4913 list was not freed on interpreter shutdown.
4914
Georg Brandl21e99f42010-03-07 15:23:59 +00004915- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004916 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004917
Georg Brandl3ee81df2008-05-17 18:14:43 +00004918- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4919 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004920 to compact the internal free lists of pre-allocted ints and floats.
4921
Georg Brandl3ee81df2008-05-17 18:14:43 +00004922- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4923 calls. Python expected the return type int but the fork familie
4924 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004925
Georg Brandl3ee81df2008-05-17 18:14:43 +00004926- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00004938- Patch #1473257: generator objects gain a gi_code attribute. This is
4939 the same object as the func_code attribute of the function that
4940 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004941
Georg Brandl3ee81df2008-05-17 18:14:43 +00004942- Issue #1920: "while 0" statements were completely removed by the
4943 compiler, even in the presence of an "else" clause, which is
4944 supposed to be run when the condition is false. Now the compiler
4945 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004946
Guido van Rossumeead05f2008-01-24 18:21:02 +00004947- A few crashers fixed: weakref_in_del.py (issue #1377858);
4948 loosing_dict_ref.py (issue #1303614, test67.py);
4949 borrowed_ref_[34].py (not in tracker).
4950
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004951- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004952 suppressed while an extension is loaded by calling SetErrorMode in
4953 dynload_win.c. The error is still reported properly.
4954
Georg Brandl3ee81df2008-05-17 18:14:43 +00004955- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004956 several extension methods and modules do not work without unicode
4957 support.
4958
Georg Brandl26543b12008-01-21 18:36:51 +00004959- Issue #1882: when compiling code from a string, encoding cookies in the
4960 second line of code were not always recognized correctly.
4961
Georg Brandl14404b62008-01-19 19:27:05 +00004962- Issue #1679: "0x" was taken as a valid integer literal.
4963
Georg Brandl6caad7d2008-01-26 14:19:22 +00004964- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004965 added.
4966
Christian Heimesc94e2b52008-01-14 04:13:37 +00004967- sys.float_info / PyFloat_GetInfo: The floating point information
4968 object was converted from a dict to a specialized structseq object.
4969
Georg Brandl3ee81df2008-05-17 18:14:43 +00004970- Patch #1816: Added sys.flags structseq. It exposes the status of
4971 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004972
Georg Brandl3ee81df2008-05-17 18:14:43 +00004973- Objects/structseq.c: Implemented new structseq representation. The

4975 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004976
Georg Brandl3ee81df2008-05-17 18:14:43 +00004977- Patch #1700288: added a type attribute cache that caches method

5003 literals. The oparg for BUILD_MAP now indicates an estimated
5004 dictionary size. There is a new opcode, STORE_MAP, for adding
5005 entries to the dictionary.

5041 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005042
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005043- sets and frozensets now have an isdisjoint() method.

5048
Georg Brandl21e99f42010-03-07 15:23:59 +00005049- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005050 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5051 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005052
Georg Brandl3ee81df2008-05-17 18:14:43 +00005053- Issue #1686386: Tuple's tp_repr did not take into account the
5054 possibility of having a self-referential tuple, which is possible
5055 from C code. Nor did object's tp_str consider that a type's tp_str
5056 could do something that could lead to an inifinite recursion.
5057 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5058 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005059
Georg Brandl3ee81df2008-05-17 18:14:43 +00005060- Issue #1164: It was possible to trigger deadlock when using the
5061 'print' statement to write to a file since the GIL was not released
5062 as needed. Now PyObject_Print() does the right thing along with
5063 various tp_print implementations of the built-in types and those in
5064 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005065
Georg Brandl3ee81df2008-05-17 18:14:43 +00005066- Issue #1147: Exceptions were directly allowing string exceptions in

5068 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00005072
Brett Cannon1e534b52007-09-07 04:18:30 +00005073- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005074 PyObject_Call() never calling back out to Python code to trigger
5075 recursion depth updates/checks. Required the creation of a static
5076 RuntimeError instance in case normalizing an exception put the
5077 recursion check value past its limit. Fixes crashers
5078 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00005093- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005094 __*__ attributes. (Some already existed, e.g., __doc__ and
5095 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005096
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005097- Add -3 option to the interpreter to warn about features that are

5101 calls.
5102
Collin Winter62903052007-05-18 23:11:24 +00005103- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005104 "except E as target:". This is to provide forwards compatibility
5105 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005112- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005113 setting a plain string, ie don't expand to single letter identifiers.
5114
Raymond Hettinger13936692007-04-11 18:40:58 +00005115- Request #1191699: Slices can now be pickled.
5116
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005117- Request #1193128: str.translate() now allows a None argument for

5119 remaining characters.
5120
Georg Brandl5cb76c12007-03-21 09:00:39 +00005121- Patch #1682205: a TypeError while unpacking an iterable is no longer

5125
Guido van Rossum143b5642007-03-23 04:58:42 +00005126- Bug #1683368: The object.__init__() and object.__new__() methods are
5127 now stricter in rejecting excess arguments. The only time when
5128 either allows excess arguments is when it is not overridden and the
5129 other one is. For backwards compatibility, when both are
5130 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005131 warning later). Also, type.__init__() insists on the same signature
5132 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005133
Georg Brandl3ee81df2008-05-17 18:14:43 +00005134- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5135 object to complex using its __complex__() method before falling back
5136 to the __float__() method. Therefore, the functions in the cmath
5137 module now can operate on objects that define a __complex__()
5138 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00005156- Bug #1678647: write a newline after printing an exception in any
5157 case, even when converting the value to a string failed.
5158
Georg Brandl871f1bc2007-03-12 13:17:36 +00005159- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005160 its argument, if it exists. If not, it will work like before. This
5161 allows customizing the output of dir() in the presence of a
5162 __getattr__().

5172 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005173
Georg Brandlaa2321b2007-03-07 00:40:28 +00005174- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005175 makes the filenames the warning module prints much more sensible
5176 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00005189- Patch #1674228: when assigning a slice (old-style), check for the
5190 sq_ass_slice instead of the sq_slice slot.
5191
Georg Brandl3ee81df2008-05-17 18:14:43 +00005192- When printing an unraisable error, don't print exceptions. before
5193 the name. This duplicates the behavior whening normally printing
5194 exceptions.

5822 -- the failure just occurred later, with a more cumbersome
5823 exception.

6036 partial fix for Bug #1574584.
6037
Georg Brandl3ee81df2008-05-17 18:14:43 +00006038- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006104- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6105 with RFC 3207 and forgets any knowledge obtained from the server not
6106 obtained from the TLS negotiation itself. Patch contributed by Bill
6107 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006108
Georg Brandl3ee81df2008-05-17 18:14:43 +00006109- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006110 that the SMTP.starttls() caller no longer needs to call ehlo()
6111 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006112 does not claim to support starttls. Adds the
6113 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
6114 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006156- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00006157 works as expected. ``mmap.find`` also takes an optional ``end``
6158 parameter.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006168- itertools.chain() now has an alternate constructor,

6183 contents before adding elements from the iterable. This fix brings
6184 the behavior into line with that for list.__init__().

6194 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6195 silently miscode subclasses of those types. Now, it raises a
6196 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006197

Georg Brandl3ee81df2008-05-17 18:14:43 +00006212 time so that opening a database previously created with the DB_DUP
6213 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6214 opens. Specifically: dictionary assignment to a DB object will
6215 replace all values for a given key when the database allows
6216 duplicate values. DB users should use DB.put(k, v) when they want
6217 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006218

6224 characters with ASCII value less than 32. Also, it correctly quotes
6225 dots only if they occur on a single line, as opposed to the previous
6226 behavior of quoting dots if they are the second character of any
6227 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006228

6550-----
6551
Georg Brandl3ee81df2008-05-17 18:14:43 +00006552- Unified naming convention for free lists and their limits. All free
6553 lists in Object/ are named ``free_list``, the counter ``numfree``
6554 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
6555 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00006556
Georg Brandl3ee81df2008-05-17 18:14:43 +00006557- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6558 to ``PyTuple_SetItem``, it can be used to populate a brand new
6559 frozenset; but it does not steal a reference to the added item.

6571
Georg Brandl3ee81df2008-05-17 18:14:43 +00006572- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6573 of w# format code incorrectly truncated the length to an int, even
6574 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6575 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006576
Georg Brandl3ee81df2008-05-17 18:14:43 +00006577- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

6595- Fix some leftovers from the conversion from int to Py_ssize_t
6596 (relevant to strings and sequences of more than 2**31 items).
6597
6598- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6599 outside of pystate.c and should not be necessary.
6600
Georg Brandl3ee81df2008-05-17 18:14:43 +00006601- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6602 absolute imports. In earlier versions they might have used relative
6603 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006604
Georg Brandl3ee81df2008-05-17 18:14:43 +00006605- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6606 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006607
Georg Brandl3ee81df2008-05-17 18:14:43 +00006608- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

6618 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00006619

Georg Brandl3ee81df2008-05-17 18:14:43 +00006633- Removed the macfs module. It had been deprecated since Python 2.5.
6634 This lead to the deprecation of macostools.touched() as it relied
6635 solely on macfs and was a no-op under OS X.
