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

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

65 characters that appear inside quoted strings in email addresses.
66
R. David Murray20ad3632010-10-01 15:48:49 +000067- Issue #10004: quoprimime no longer generates a traceback when confronted

71 received. Now sendall() properly calls signal handlers if necessary,
72 and retries sending if these returned successfully, including on sockets

80
Antoine Pitrou2c7d6852010-09-23 19:55:24 +000081- Issue #9928: Properly initialize the types exported by the bz2 module.
82
Antoine Pitrou6391b342010-09-14 18:48:19 +000083- Issue #9854: The default read() implementation in io.RawIOBase now
84 handles non-blocking readinto() returning None correctly.
85
Antoine Pitrouf7f390a2010-09-14 14:37:18 +000086- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
87 SSLSocket.sendto() to match the corresponding socket methods. Also,
88 fix various SSLSocket methods to raise socket.error rather than an
89 unhelpful TypeError when called on an unconnected socket. Original patch
90 by Andrew Bennetts.
91
Raymond Hettinger74f869e2010-09-13 22:14:36 +000092- Issue #9826: OrderedDict.__repr__ can now handle self-referential
93 values: d['x'] = d.

98 ZipFile.open()) could return more bytes than requested.
99
Raymond Hettinger20397532010-09-12 02:11:45 +0000100- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
101 This prevents user-created self-referencing ordered dictionaries from
102 becoming permanently uncollectable GC garbage. The downside is that
103 removing __del__ means that the internal doubly-linked list has to wait for
104 GC collection rather than freeing memory immediately when the refcnt drops
105 to zero.
106
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000107- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
108 different internal state for small values of n. Fixed by salting the
109 value.
110
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000111- Issue #9792: In case of connection failure, socket.create_connection()
112 would swallow the exception and raise a new one, making it impossible
113 to fetch the original errno, or to filter timeout errors. Now the
114 original error is re-raised.
115
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000116- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
117 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
118 be updated back after the system call. Original patch by Brian Brazil.
119
Antoine Pitroudca9de92010-09-04 17:52:26 +0000120- Issue #1100562: Fix deep-copying of objects derived from the list and
121 dict types. Patch by Michele Orrù and Björn Lindqvist.
122
Fred Drakea1e627d2010-09-03 03:55:50 +0000123- Issue #7005: Fixed output of None values for RawConfigParser.write and
124 ConfigParser.write.
125
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000126- Issue #808164: Fixed socket.close to avoid references to globals, to
127 avoid issues when socket.close is called from a __del__ method.
128
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +0000129- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
130 falling into recursion.
131
R. David Murray7c4bf552010-08-25 01:45:57 +0000132- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
133 character years even if the message contains RFC822 two character years.
134
Daniel Stutzbach91287322010-08-24 21:09:30 +0000135- Issue #8750: Fixed MutableSet's methods to correctly handle
136 reflexive operations, namely x -= x and x ^= x.
137
Victor Stinnercaafd772010-09-08 10:51:01 +0000138- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing
Giampaolo Rodolà8664d742010-08-23 22:48:51 +0000139 error handling when accepting a new connection.
140
Giampaolo Rodolà63308d72010-08-23 21:58:47 +0000141- Issue #658749: asyncore's connect() method now correctly interprets winsock

150 ignored by the buffered IO layer anymore.
151
Benjamin Peterson52c36052010-08-21 03:03:22 +0000152- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
153 are not held onto after they are deleted elsewhere.
154
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000155- Issue #9626: the view methods for collections.OrderedDict() were returning
156 the unordered versions inherited from dict. Those methods are now
157 overridden to provide ordered views.
158
Éric Araujo0389ae62010-08-14 03:07:46 +0000159- Issue #8688: MANIFEST files created by distutils now include a magic
160 comment indicating they are generated. Manually maintained MANIFESTs
161 without this marker will not be overwritten or removed.
162
Antoine Pitroue1436d12010-08-12 15:25:51 +0000163- Issue #7467: when reading a file from a ZIP archive, its CRC is checked

166
Antoine Pitroucb4f47c2010-08-11 13:40:17 +0000167- Issue #9550: a BufferedReader could issue an additional read when the

170 patch by Jason V. Miller.
171
Fred Drake0a1fa0e2010-08-10 13:09:54 +0000172- Issue #9551: Don't raise TypeError when setting the value to None for

177
Antoine Pitrou99009162010-08-09 22:51:24 +0000178- Issue #3757: thread-local objects now support cyclic garbage collection.
179 Thread-local objects involved in reference cycles will be deallocated
180 timely by the cyclic GC, even if the underlying thread is still running.
181

192 behavior was wrong.
193

553 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000911 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
912 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
913 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

933Core and Builtins
934-----------------
935
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000936- Issue #7301: Add environment variable $PYTHONWARNINGS.
937
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000938- Issue #8329: Don't return the same lists from select.select when no fds are
939 changed.
940
Georg Brandlfee0f442010-05-22 21:26:21 +0000941- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000942 on 64-bit machines. The shift count for either left or right shift is
943 permitted to be up to sys.maxsize.
944
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000945- Ensure that tokenization of identifiers is not affected by locale.
946
Georg Brandlfee0f442010-05-22 21:26:21 +0000947- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000949- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
950
Georg Brandlfee0f442010-05-22 21:26:21 +0000951- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
952 with a non-empty format string. This is an effort to future-proof user
953 code. If a derived class does not currently implement __format__ but later
954 adds its own __format__, it would most likely break user code that had
955 supplied a format string. This will be changed to a DeprecationWaring in
956 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000957
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000958- Issue #8268: Old-style classes (not just instances) now support weak

982
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000983- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000984 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and

988
Georg Brandlfee0f442010-05-22 21:26:21 +0000989- Issue #8257: The Decimal construct now accepts a float instance directly,
990 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000991
992 >>> Decimal(1.1)
993 Decimal('1.100000000000000088817841970012523233890533447265625')
994
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000995- collections.Counter() now supports a subtract() method.
996
Georg Brandlfee0f442010-05-22 21:26:21 +0000997- The functools module now has a total_ordering() class decorator to simplify
998 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000999
Georg Brandlfee0f442010-05-22 21:26:21 +00001000- The functools module also adds cmp_to_key() as a tool to transition old-style
1001 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001002
Georg Brandlfee0f442010-05-22 21:26:21 +00001003- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1004 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00001005
Georg Brandlfee0f442010-05-22 21:26:21 +00001006- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1007 InvalidOperation instead of returning False. (Comparisons involving a quiet
1008 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1009 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001010
Georg Brandlfee0f442010-05-22 21:26:21 +00001011- Issue #2531: Comparison operations between floats and Decimal instances now
1012 return a result based on the numeric values of the operands; previously they
1013 returned an arbitrary result based on the relative ordering of id(float) and
1014 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001015
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001016- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001017 argument `-` which tells it to read files to compile from stdin. Each line is
1018 read on demand and the named file is compiled immediately. (Original patch by
1019 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001020
Georg Brandlfee0f442010-05-22 21:26:21 +00001021- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00001024- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1025 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001026 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001027
Georg Brandlfee0f442010-05-22 21:26:21 +00001028- Comparisons using one of <, <=, >, >= between a complex instance and a
1029 Fractions instance now raise TypeError instead of returning True/False. This
1030 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1031 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001032
Michael Foorde6410c52010-03-29 20:04:23 +00001033- Addition of ``WeakSet`` to the ``weakref`` module.

1041
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001042- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001043 didn't support chflags() (for example ZFS under FreeBSD). The error is now
1044 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001045
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00001046- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
1047 deprecated.
1048
Georg Brandlfee0f442010-05-22 21:26:21 +00001049- Issue #7860: platform.uname now reports the correct 'machine' type when Python

Vinay Sajipecfa08f2010-03-12 09:16:10 +00001086- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001087 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1088 log file to compute the next rollover time. If the log file does not exist,
1089 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00001090

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001130- Issue #8300: When passing a non-integer argument to struct.pack with any
1131 integer format code, struct.pack first attempts to convert the non-integer
1132 using its __index__ method. If that method is non-existent or raises
1133 TypeError it goes on to try the __int__ method, as described below.
1134
Georg Brandlba83f822010-03-14 09:50:54 +00001135- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1136 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1137 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001138 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1139 inconsistent: __int__ was used for some integer codes but not for others, and
1140 the set of integer codes for which it was used differed between native packing
1141 and standard packing.)

1369 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00001370 library would return a bogus result; on Solaris, it was possible to crash the

Georg Brandlba83f822010-03-14 09:50:54 +00001389- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
1390 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1391 returning NULL. The macro now returns a statically allocated empty string
1392 instead.

1402 strings,
1403 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
1404 numeric strings corresponding to subnormal values,
1405 (3) a memory leak for some values large enough to cause overflow, and
1406 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00001437- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00001438 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001444- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001445 file position when calling `truncate()`. It would previously change the file
1446 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001447 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1448
Georg Brandlba83f822010-03-14 09:50:54 +00001449- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1450 class used to represent files stored inside an archive. The new
1451 implementation is significantly faster and can be wrapped in a
1452 ``io.BufferedReader`` object for more speedups. It also solves an issue
1453 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
1454 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00001464- Issue #7748: Since unicode values are supported for some metadata options in
1465 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1466 encoded string for them. This ensures that the upload and register commands
1467 send the correct values to PyPI without any error.

1552 These functions and methods now raise TypeError instead. The majority of the
1553 effects of this change are in the extension modules, but some core functions
1554 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1555 and many unicode/str methods.

1569 of integers: the result of a/b is now correctly rounded for ints a and b (at
1570 least on IEEE 754 platforms), and in particular does not depend on the
1571 internal representation of a long.

1579
Georg Brandlba83f822010-03-14 09:50:54 +00001580 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00001738- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1739 decimal string that's guaranteed to round back to x under correct rounding
1740 (with round-half-to-even rounding mode). Previously it gave a string based on
1741 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1742 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1743 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001744
Georg Brandlba83f822010-03-14 09:50:54 +00001745- Issue #7117: On almost all platforms: float-to-string and string-to-float
1746 conversions within Python are now correctly rounded. Places these conversions
1747 occur include: str for floats and complex numbers; the float and complex
1748 constructors; old-style and new-style numeric formatting; serialization and
1749 deserialization of floats and complex numbers using marshal, pickle and json;
1750 parsing of float and imaginary literals in Python code; Decimal-to-float
1751 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001752
Georg Brandlba83f822010-03-14 09:50:54 +00001753 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1754 providing correctly-rounded strtod and dtoa C functions. This code is
1755 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1756 the C compiler. There may be a small number of platforms on which correct
1757 operation of this code cannot be guaranteed, so the code is not used: notably,
1758 this applies to platforms where the C double format is not IEEE 754 binary64,
1759 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1760 and Python's configure script is unable to determine how to change the FPU
1761 precision. On these platforms conversions use the platform strtod and dtoa,
1762 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001764- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1765 uses the correctly-rounded string <-> float conversions described above (when
1766 available), and so produces correctly rounded results that will display nicely
1767 under the float repr. There are two related small changes: (1) round now
1768 accepts any class with an ``__index__()`` method for its second argument (but
1769 no longer accepts floats for the second argument), and (2) an excessively
1770 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1771 raises an exception.

1921 of 12. Previously, the behavior the same but with a default precision of 6.
1922 This more closely matches ``str()``, and reduces surprises when adding

Georg Brandlba83f822010-03-14 09:50:54 +00002045- Issue #4935: The overflow checking code in the expandtabs() method common to
2046 str, bytes and bytearray could be optimized away by the compiler, letting the
2047 interpreter segfault instead of raising an error.

2063
Georg Brandlba83f822010-03-14 09:50:54 +00002064- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2065 existing .py counterpart, override the co_filename attributes of all code
2066 objects if the original filename is obsolete (which can happen if the file has
2067 been renamed, moved, or if it is accessed through different paths). Patch by

2108 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2109 instances. On a typical machine this saves 3 bytes of memory (on average) per

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002112- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

2114 instead of throwing a MemoryError.
2115
Georg Brandlba83f822010-03-14 09:50:54 +00002116- Issue #3689: The list reversed iterator now supports __length_hint__ instead

2121
Georg Brandlba83f822010-03-14 09:50:54 +00002122- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2123 file objects with closefd=False. The file descriptor is still kept open but
2124 the file object behaves like a closed file. The ``FileIO`` object also got a
2125 new readonly attribute ``closefd``.

2144
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002145- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00002146 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00002148- On windows, ``os.chdir()`` given unicode was not working if
2149 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2150 this code path is really executed because I cannot move to such directory on
2151 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002153- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2154 element is temporarily replaced with an equivalent frozenset. But the
2155 eventual KeyError would always report the empty ``frozenset()`` as the missing
2156 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00002176- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2177 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2178 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2179 of using the replace error handler in PyUnicode_DecodeUTF8().
2180
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002181- Issue #3739: The unicode-internal encoder now reports the number of characters

2183
Georg Brandlba83f822010-03-14 09:50:54 +00002184- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2185 allocator will be automatically disabled when running under Valgrind. This
2186 gives improved memory leak detection when running under Valgrind, while taking
2187 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00003410 leak-chasing test runs give sensible results. The previous method of reaping
3411 threads could return successfully while some Thread objects were still
3412 referenced. This also introduces a new private function: ``thread._count()``.

R. David Murray14dcd432009-10-14 13:58:07 +00003420- Issue #7058: Added save/restore for things like sys.argv and cwd to

3422 and a new section in the summary report at the end.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00003429- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
3430 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00003431 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
3432 the tests if DISPLAY is defined but can't be used.

Georg Brandlba83f822010-03-14 09:50:54 +00003437- Issue #5354: New test support function import_fresh_module() makes it easy to
3438 import both normal and optimised versions of modules. test_heapq and
3439 test_warnings have been adjusted to use it, tests for other modules with both
3440 C and Python implementations in the stdlib can be adjusted to use it over
3441 time.

Georg Brandlba83f822010-03-14 09:50:54 +00003449- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
3450 should cause a test to be skipped are now done using import_module from test
3451 support, which does the conversion.

3553
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003554- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3555 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3556 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3557 ``printf`` function, whereas PyString_FromFormat has an independent
3558 implementation and uses "%zd" on all platforms for size_t values.
3559 This makes a difference on win64, where ``printf`` needs "%Id" to display
3560 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00003562- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3566 object; previously an int would be returned for small values. the __long__
3567 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003577 was correctly parsed but parsing of subsequent arguments failed.

Vinay Sajip35e3b032008-09-01 14:33:59 +00003579- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003580 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3581 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3582 when given a tuple of classes as second argument, were looking up
3583 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3584 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003723What's New in Python 2.6 beta 3?
3724================================
3725
Barry Warsaw07a4a382008-08-21 01:15:08 +00003726*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003727
3728Core and Builtins
3729-----------------
3730
Guido van Rossumf8402962008-08-20 15:01:50 +00003731- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3732 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3733 extensions do not automatically benefit from the class attribute
3734 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3735 to their tp_flags field if they care. This is a backwards
3736 compatibility feature; in 3.0, all types will use the cache by
3737 default.
3738
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003739- Keyword arguments can now follow starred arguments. (``f(a, *args,
3740 keyword=23)`` is now valid syntax.)
3741
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003742- ctypes function pointers that are COM methods have a boolean True
3743 value again.
3744
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003745- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3746 by denying s# to parse objects that have a releasebuffer procedure,
3747 and introducing s*.
3748
Georg Brandl1e13ea92008-08-11 09:07:59 +00003749- Issue #3537: Fix an assertion failure when an empty but presized dict
3750 object was stored in the freelist.
3751
Mark Dickinsonb6467572008-08-04 21:30:09 +00003752- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3753 ValueError consistently across platforms.
3754
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003755- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3756 (64bit Unix, for example), unichr() would truncate its argument and return
3757 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3758
Neal Norwitze7d8be82008-07-31 17:17:14 +00003759- Apply security patches from Apple.
3760
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003761- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3762 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3763
Antoine Pitrou92f82162008-07-25 22:22:08 +00003764- Issue #1819: function calls with several named parameters are now on
3765 average 35% faster (as measured by pybench).
3766
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003767- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3768 the python debugger steps into a class statement: the free variables (local
3769 variables defined in an outer scope) would be deleted from the outer scope.
3770
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003771- Issue #2620: Overflow checking when allocating or reallocating memory
3772 was not always being done properly in some python types and extension
3773 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3774 all been updated to perform better checks and places in the code that
3775 would previously leak memory on the error path when such an allocation
3776 failed have been fixed.

3779-------
3780
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003781- Issue #3612: Added some missing basic types in ctypes.wintypes.
3782
Benjamin Petersone977ad42008-08-20 01:42:01 +00003783- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3784 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3785
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003786- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3787 version reported by these tools does not necessarily follow the python
3788 version numbering scheme, so the module is less strict when parsing it.
3789
Nick Coghlanf70385a2008-08-18 12:42:46 +00003790- Issue #2235: Added Py3k warnings for types which will become unhashable
3791 under the stricter __hash__ inheritance rules in 3.0. Several types
3792 which did not meet the rules for hash invariants and were already
3793 unhashable in 3.0 have now been explicitly flagged as unhashable in
3794 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3795 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3796
Brett Cannon88f801d2008-08-18 00:46:22 +00003797- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3798 imported into the module but exposed as part of the module's API.
3799
Brett Cannon7b96f072008-08-18 00:41:11 +00003800- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3801
Brett Cannon46225e72008-08-18 00:36:52 +00003802- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
3803
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003804- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3805
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003806- Issue #3575: Incremental decoder's decode function now takes bytearray
3807 by using 's*' instead of 't#'.
3808
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003809- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003810 fails unicode conversion on 2nd parameter. (windows only)
3811
Georg Brandl222e2082010-08-01 22:27:39 +00003812- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003813 in a redirect.
3814
Brett Cannonabe423e2008-08-16 21:47:07 +00003815- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003816 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003817
Facundo Batistaeb90b782008-08-16 14:44:07 +00003818- Issue #2776: fixed small issue when handling an URL with double slash
3819 after a 302 response in the case of not going through a proxy.
3820
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003821- Issue #2676: in the email package, content-type parsing was hanging on
3822 pathological input because of quadratic or exponential behaviour of a
3823 regular expression.
3824
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003825- Issue #3476: binary buffered reading through the new "io" library is now
3826 thread-safe.
3827
Brett Cannonbf3157b2008-08-14 05:00:03 +00003828- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3829 since mimetools itself is deprecated. Because modules are cached, all
3830 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3831
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003832- Issue #3134: shutil referenced undefined WindowsError symbol.
3833
Robert Schuppenies14646332008-08-10 11:01:53 +00003834- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3835 menu entries were not deleted.
3836
Brett Cannon83e81842008-08-09 23:30:55 +00003837- Copied the implementation of reduce() to _functools.reduce() to have a
3838 version that did not raise a DeprecationWarning under -3.
3839
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003840- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3841 a MemoryError rather than silently stop the iteration.
3842
Guido van Rossum59ce9012008-08-09 14:55:34 +00003843- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3844 to _sre.compile() will now be rejected. This should not affect anybody
3845 since the re.compile() function never generates invalid re-bytecode.
3846
Skip Montanaroa032bf42008-08-08 22:52:51 +00003847- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3848 upon first access it can be automatically initialized from the csv file if
3849 it wasn't initialized during instantiation.
3850
Brett Cannon3aa2a492008-08-06 22:28:09 +00003851- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3852 the reload() built-in has been removed.
3853
Brett Cannon7e30b672008-08-04 21:52:25 +00003854- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003855 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3858 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
3859 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
3860 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00003861
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00003862- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
3863 raised an AttributeError.
3864
Benjamin Peterson01a24322008-07-28 23:35:27 +00003865- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003866 asking for a specific length. This problem only affected files opened
3867 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003868
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003869- Issue #3449: Update decimal module to use most recent specification
3870 (v. 1.68) and tests (v. 2.58) from IBM.
3871
Georg Brandl222e2082010-08-01 22:27:39 +00003872- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00003873

3876
Georg Brandlf9efabb2008-07-23 15:16:45 +00003877- Deprecate the "ast" parser function aliases.
3878
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003879- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
3880
3881- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3882 invalid arguments.
3883
3884- Issue #3302: Fix several crashes when calling locale's gettext functions
3885 with None arguments.
3886
3887- Issue #3389: Allow resolving dotted names for handlers in logging
3888 configuration files.
3889
3890- Deprecate the sunaudio module for removal in Python 3.0.
3891
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003892- Issue #3394: zipfile.writestr sets external attributes when passed a
3893 file name rather than a ZipInfo instance, so files are extracted with
3894 mode 0600 rather than 000 under Unix.
3895
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003896- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3897 argument in python 2.5, this broke code that subclassed Popen to include its
3898 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3909 interaction with the tp_hash slot (added in 2.6b2) are now documented
3910
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003911- Issue #643841: The language reference now provides more detailed
3912 coverage of the lookup process for special methods. The disclaimers
3913 regarding lack of coverage of new-style classes have also been
3914 removed, since the coverage is now fairly reasonable.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003920*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003922Core and Builtins
3923-----------------
3924
Georg Brandl3e483f62008-07-16 22:57:41 +00003925- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3926 its methods now allow for items objects that can be converted to
3927 an integer using operator.index().
3928
Mark Dickinson64b7e502008-07-16 09:40:03 +00003929- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3930 produced a ValueError instead of giving the correct float.
3931
Eric Smitha5fa5a22008-07-16 00:11:49 +00003932- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3933 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3934
Mark Dickinson7103aa42008-07-15 19:08:33 +00003935- Issue #3008: the float type has a new instance method 'float.hex'
3936 and a new class method 'float.fromhex' to convert floating-point
3937 numbers to and from hexadecimal strings, respectively.
3938
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003939- Issue #2235: __hash__ is once again inherited by default. To allow
3940 collections.Hashable to remain meaningful in the presence of the
3941 default hash implementation (object.__hash__), it is now possible
3942 to explicit block inheritance of hash by setting __hash__=None at
3943 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3944 level.
3945
Nick Coghlanb028f502008-07-13 14:52:36 +00003946- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3947 the parent module cannot be found while performing an absolute import.
3948 This means that an incorrectly defined __package__ attribute will
3949 now only prevent relative imports in that module rather than causing
3950 all imports from that module to fail.
3951
Nick Coghlan14ff9942008-07-08 14:21:42 +00003952- Issue #2517: Allow unicode messages in Exceptions again by correctly
3953 bypassing the instance dictionary when looking up __unicode__ on
3954 new-style classes.
3955
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003956- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3957 set to a custom object whose write() method happens to install
3958 another file in sys.stdout.

3962 another thread's dictionary.
3963
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003964- Issue #3004: Minor change to slice.indices(): the start and stop
3965 arguments are now treated identically, making the behaviour easier
3966 to describe and understand. For example, slice(None, -10,
3967 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3968 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3969 10, -1).
3970
Georg Brandl278fc502008-07-19 12:46:12 +00003971- Issue #3219: Calling a function with repeated keyword arguments,
3972 f(a=2, a=23), would not cause a syntax error. This was a regression
3973 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00004423 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004424
4425 This is controlled by the configure argument ``--with-universal-archs``:
4426
4427 - ``--with-universal-archs=all``: install 4-way universal
4428
4429 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4430
4431 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4432
4433 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004485- Issue #1631171: Re-implement the 'warnings' module in C (the
4486 original Python code has been kept as backup). This will allow for
4487 using the 'warning's machinery in such places as the parser where
4488 use of pure Python code is not possible. Both the ``showarning()``
4489 and ``formatwarning()`` gain an optional 'line' argument which is
4490 not called by default for backwards-compatibility reasons. Setting
4491 ``warnings.showwarning()`` to an implementation that lacks support
4492 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004555- Issue #2550: The approach used by client/server code for obtaining
4556 ports to listen on in network-oriented tests has been refined in an
4557 effort to facilitate running multiple instances of the entire
4558 regression test suite in parallel without issue.
4559 test_support.bind_port() has been fixed such that it will always
4560 return a unique port -- which wasn't always the case with the
4561 previous implementation, especially if socket options had been set
4562 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4563 new implementation of bind_port() will actually raise an exception
4564 if it is passed an AF_INET/SOCK_STREAM socket with either the
4565 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4566 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4567 the socket it's been passed. This currently only applies to
4568 Windows. This option prevents any other sockets from binding to the
4569 host/port we've bound to, thus removing the possibility of the
4570 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4571 when a second SOCK_STREAM socket binds and accepts to a host/port
4572 that's already been bound by another socket. The optional preferred
4573 port parameter to bind_port() has been removed. Under no
4574 circumstances should tests be hard coding ports!
4575
4576 test_support.find_unused_port() has also been introduced, which will
4577 pass a temporary socket object to bind_port() in order to obtain an
4578 unused port. The temporary socket object is then closed and
4579 deleted, and the port is returned. This method should only be used
4580 for obtaining an unused port in order to pass to an external program
4581 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4582 a parameter to a server-oriented class that doesn't give you direct
4583 access to the underlying socket used.
4584
4585 Finally, test_support.HOST has been introduced, which should be used
4586 for the host argument of any relevant socket calls (i.e. bind and
4587 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004588
4589 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004590 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004591 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4592 test_asynchat and test_socket_ssl.
4593
Georg Brandl3ee81df2008-05-17 18:14:43 +00004594 It is now possible for multiple instances of the regression test
4595 suite to run in parallel without issue.

Thomas Heller78b8f442008-03-05 14:53:39 +00004799- The bundled libffi copy is now in sync with the recently released
4800 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004801 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
4802 files are used. On all linux systems the --with-system-ffi
4803 configure option defaults to "yes".

Fred Drakea8ee94b2008-03-01 02:45:07 +00004864- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004865 644. The mode is now inherited from the py file.

Facundo Batistafc2d0102008-02-23 12:01:13 +00004873
Eric Smitha73fbe72008-02-23 03:09:44 +00004874- Added the future_builtins module, which contains hex() and oct().
4875 These are the PEP 3127 version of these functions, designed to be
4876 compatible with the hex() and oct() builtins from Python 3.0. They
4877 differ slightly in their output formats from the existing, unchanged
4878 Python 2.6 builtins. The expected usage of the future_builtins
4879 module is:
4880 from future_builtins import hex, oct
4881
Eric Smith7ef40bf2008-02-20 23:34:22 +00004882- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4883 exponents for exponents with absolute value < 100. Follows C99
4884 standard. This is a change on Windows, which would use 3 digits.
4885 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4886 so that any alterations it does to the resulting string will be
4887 available in stringlib/formatter.h (for float.__format__).
4888
Eric Smith5a3c1352008-02-19 13:21:56 +00004889- Implemented PEP 3101, Advanced String Formatting. This adds a new
4890 builtin format(); a format() method for str and unicode; a
4891 __format__() method to object, str, unicode, int, long, float, and
4892 datetime; the class string.Formatter; and the C API
4893 PyObject_Format().
4894
Georg Brandl3ee81df2008-05-17 18:14:43 +00004895- Fixed several potential crashes, all caused by specially crafted
4896 __del__ methods exploiting objects in temporarily inconsistent
4897 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004898
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004899- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004900 prevent a possible crash: an Abstract Base Class would try to access
4901 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004902

Georg Brandl3ee81df2008-05-17 18:14:43 +00004906- Clear all free lists during a gc.collect() of the highest generation
4907 in order to allow pymalloc to free more arenas. Python may give back
4908 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004909
Georg Brandl3ee81df2008-05-17 18:14:43 +00004910- Issue #2045: Fix an infinite recursion triggered when printing a
4911 subclass of collections.defaultdict, if its default_factory is set
4912 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004913
Christian Heimesf75dbef2008-02-08 00:11:31 +00004914- Fixed a minor memory leak in dictobject.c. The content of the free
4915 list was not freed on interpreter shutdown.
4916
Georg Brandl21e99f42010-03-07 15:23:59 +00004917- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004918 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004919
Georg Brandl3ee81df2008-05-17 18:14:43 +00004920- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4921 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004922 to compact the internal free lists of pre-allocted ints and floats.
4923
Georg Brandl3ee81df2008-05-17 18:14:43 +00004924- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4925 calls. Python expected the return type int but the fork familie
4926 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004927
Georg Brandl3ee81df2008-05-17 18:14:43 +00004928- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4929 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004940- Patch #1473257: generator objects gain a gi_code attribute. This is
4941 the same object as the func_code attribute of the function that
4942 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004943
Georg Brandl3ee81df2008-05-17 18:14:43 +00004944- Issue #1920: "while 0" statements were completely removed by the
4945 compiler, even in the presence of an "else" clause, which is
4946 supposed to be run when the condition is false. Now the compiler
4947 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004948
Guido van Rossumeead05f2008-01-24 18:21:02 +00004949- A few crashers fixed: weakref_in_del.py (issue #1377858);
4950 loosing_dict_ref.py (issue #1303614, test67.py);
4951 borrowed_ref_[34].py (not in tracker).
4952
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004953- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004954 suppressed while an extension is loaded by calling SetErrorMode in

4956
Georg Brandl3ee81df2008-05-17 18:14:43 +00004957- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004958 several extension methods and modules do not work without unicode
4959 support.
4960
Georg Brandl26543b12008-01-21 18:36:51 +00004961- Issue #1882: when compiling code from a string, encoding cookies in the
4962 second line of code were not always recognized correctly.
4963
Georg Brandl14404b62008-01-19 19:27:05 +00004964- Issue #1679: "0x" was taken as a valid integer literal.
4965
Georg Brandl6caad7d2008-01-26 14:19:22 +00004966- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004967 added.
4968
Christian Heimesc94e2b52008-01-14 04:13:37 +00004969- sys.float_info / PyFloat_GetInfo: The floating point information
4970 object was converted from a dict to a specialized structseq object.
4971
Georg Brandl3ee81df2008-05-17 18:14:43 +00004972- Patch #1816: Added sys.flags structseq. It exposes the status of
4973 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004974
Georg Brandl3ee81df2008-05-17 18:14:43 +00004975- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00005001 and INF. float("nan"), float("inf") and float("-inf") now work on
5002 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005003
Georg Brandl3ee81df2008-05-17 18:14:43 +00005004- Compiler now generates simpler and faster code for dictionary
5005 literals. The oparg for BUILD_MAP now indicates an estimated
5006 dictionary size. There is a new opcode, STORE_MAP, for adding
5007 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005036- Patch #1739468: Directories and zipfiles containing a __main__.py
5037 file can now be directly executed by passing their name to the
5038 interpreter. The directory/zipfile is automatically inserted as the
5039 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005041- Issue #1265: Fix a problem with sys.settrace, if the tracing
5042 function uses a generator expression when at the same time the
5043 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005044
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005045- sets and frozensets now have an isdisjoint() method.
5046

5048
Neal Norwitz44f326e2007-10-05 05:29:17 +00005049- Fix warnings found by the new version of the Coverity checker.
5050
Georg Brandl21e99f42010-03-07 15:23:59 +00005051- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005052 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5053 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005054
Georg Brandl3ee81df2008-05-17 18:14:43 +00005055- Issue #1686386: Tuple's tp_repr did not take into account the
5056 possibility of having a self-referential tuple, which is possible
5057 from C code. Nor did object's tp_str consider that a type's tp_str
5058 could do something that could lead to an inifinite recursion.
5059 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5060 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005061
Georg Brandl3ee81df2008-05-17 18:14:43 +00005062- Issue #1164: It was possible to trigger deadlock when using the
5063 'print' statement to write to a file since the GIL was not released
5064 as needed. Now PyObject_Print() does the right thing along with
5065 various tp_print implementations of the built-in types and those in
5066 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005067
Georg Brandl3ee81df2008-05-17 18:14:43 +00005068- Issue #1147: Exceptions were directly allowing string exceptions in
5069 their throw() method even though string exceptions no longer
5070 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005071
Georg Brandl3ee81df2008-05-17 18:14:43 +00005072- Issue #1096: Prevent a segfault from getting the repr of a very
5073 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005074
Brett Cannon1e534b52007-09-07 04:18:30 +00005075- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005076 PyObject_Call() never calling back out to Python code to trigger
5077 recursion depth updates/checks. Required the creation of a static
5078 RuntimeError instance in case normalizing an exception put the
5079 recursion check value past its limit. Fixes crashers
5080 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005081
Georg Brandl3ee81df2008-05-17 18:14:43 +00005082- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00005095- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005096 __*__ attributes. (Some already existed, e.g., __doc__ and
5097 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005098
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005099- Add -3 option to the interpreter to warn about features that are
5100 deprecated and will be changed/removed in Python 3.0.
5101
Georg Brandl2134e752007-05-21 20:34:16 +00005102- Patch #1686487: you can now pass any mapping after '**' in function
5103 calls.
5104
Collin Winter62903052007-05-18 23:11:24 +00005105- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005106 "except E as target:". This is to provide forwards compatibility
5107 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005108
Brett Cannon229cee22007-05-05 01:34:02 +00005109- Deprecate BaseException.message as per PEP 352.
5110
Georg Brandl3ee81df2008-05-17 18:14:43 +00005111- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005112 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005113
Vinay Sajip8549ce32007-05-06 17:53:37 +00005114- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005115 setting a plain string, ie don't expand to single letter identifiers.
5116
Raymond Hettinger13936692007-04-11 18:40:58 +00005117- Request #1191699: Slices can now be pickled.
5118
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005119- Request #1193128: str.translate() now allows a None argument for
5120 translations that only remove characters without re-mapping the
5121 remaining characters.
5122
Georg Brandl5cb76c12007-03-21 09:00:39 +00005123- Patch #1682205: a TypeError while unpacking an iterable is no longer

5125
Neal Norwitzaa754b72007-03-21 06:39:48 +00005126- Remove unused file Python/fmod.c.
5127
Guido van Rossum143b5642007-03-23 04:58:42 +00005128- Bug #1683368: The object.__init__() and object.__new__() methods are
5129 now stricter in rejecting excess arguments. The only time when
5130 either allows excess arguments is when it is not overridden and the
5131 other one is. For backwards compatibility, when both are
5132 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005133 warning later). Also, type.__init__() insists on the same signature
5134 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005135
Georg Brandl3ee81df2008-05-17 18:14:43 +00005136- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5137 object to complex using its __complex__() method before falling back
5138 to the __float__() method. Therefore, the functions in the cmath
5139 module now can operate on objects that define a __complex__()
5140 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005141
Georg Brandl3ee81df2008-05-17 18:14:43 +00005142- Patch #1623563: allow __class__ assignment for classes with
5143 __slots__. The old and the new class are still required to have the
5144 same slot names.

5150 ``object.__reduce_ex__()`` is called with an object that is faking
5151 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005152
Georg Brandl3ee81df2008-05-17 18:14:43 +00005153- Patch #1680015: Don't modify __slots__ tuple if it contains an

5157
Georg Brandl7b9c5552007-03-12 14:30:05 +00005158- Bug #1678647: write a newline after printing an exception in any
5159 case, even when converting the value to a string failed.
5160
Georg Brandl871f1bc2007-03-12 13:17:36 +00005161- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005162 its argument, if it exists. If not, it will work like before. This
5163 allows customizing the output of dir() in the presence of a
5164 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005172- Patch #1491866: change the complex() constructor to allow
5173 parthensized forms. This means complex(repr(x)) now works instead of
5174 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005175
Georg Brandlaa2321b2007-03-07 00:40:28 +00005176- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005177 makes the filenames the warning module prints much more sensible
5178 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005179

Georg Brandl0fca97a2007-03-05 22:28:08 +00005191- Patch #1674228: when assigning a slice (old-style), check for the
5192 sq_ass_slice instead of the sq_slice slot.
5193
Georg Brandl3ee81df2008-05-17 18:14:43 +00005194- When printing an unraisable error, don't print exceptions. before
5195 the name. This duplicates the behavior whening normally printing
5196 exceptions.

5824 -- the failure just occurred later, with a more cumbersome
5825 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006106- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6107 with RFC 3207 and forgets any knowledge obtained from the server not
6108 obtained from the TLS negotiation itself. Patch contributed by Bill
6109 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006110
Georg Brandl3ee81df2008-05-17 18:14:43 +00006111- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006112 that the SMTP.starttls() caller no longer needs to call ehlo()
6113 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006114 does not claim to support starttls. Adds the
6115 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

6196 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6197 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00006199

Georg Brandl3ee81df2008-05-17 18:14:43 +00006214 time so that opening a database previously created with the DB_DUP
6215 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6216 opens. Specifically: dictionary assignment to a DB object will
6217 replace all values for a given key when the database allows
6218 duplicate values. DB users should use DB.put(k, v) when they want
6219 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006220

6226 characters with ASCII value less than 32. Also, it correctly quotes
6227 dots only if they occur on a single line, as opposed to the previous
6228 behavior of quoting dots if they are the second character of any
6229 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006230

6552-----
6553
Georg Brandl3ee81df2008-05-17 18:14:43 +00006554- Unified naming convention for free lists and their limits. All free
6555 lists in Object/ are named ``free_list``, the counter ``numfree``
6556 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
6557 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00006558
Georg Brandl3ee81df2008-05-17 18:14:43 +00006559- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6560 to ``PyTuple_SetItem``, it can be used to populate a brand new
6561 frozenset; but it does not steal a reference to the added item.

6573
Georg Brandl3ee81df2008-05-17 18:14:43 +00006574- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6575 of w# format code incorrectly truncated the length to an int, even
6576 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6577 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006578
Georg Brandl3ee81df2008-05-17 18:14:43 +00006579- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

6596
6597- Fix some leftovers from the conversion from int to Py_ssize_t
6598 (relevant to strings and sequences of more than 2**31 items).
6599
6600- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6601 outside of pystate.c and should not be necessary.
6602
Georg Brandl3ee81df2008-05-17 18:14:43 +00006603- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6604 absolute imports. In earlier versions they might have used relative
6605 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006606
Georg Brandl3ee81df2008-05-17 18:14:43 +00006607- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6608 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006609
Georg Brandl3ee81df2008-05-17 18:14:43 +00006610- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00006617- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
6618 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6619 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6620 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00006621

6634
Georg Brandl3ee81df2008-05-17 18:14:43 +00006635- Removed the macfs module. It had been deprecated since Python 2.5.
6636 This lead to the deprecation of macostools.touched() as it relied
6637 solely on macfs and was a no-op under OS X.
