Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000195- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
196 start byte and the continuation byte(s) are now considered invalid, instead
197 of the number of bytes specified by the start byte.
198 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
199 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
200 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

210 objects. (1) The comparison could incorrectly return True in some cases
211 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
212 (2) The comparison raised an OverflowError for large integers, leading

Mark Dickinson81336372010-05-30 12:12:25 +0000216- Issue #5211: Implicit coercion for the complex type is now completely

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000556 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
557 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
558 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

Benjamin Peterson5da7e7c2010-03-06 22:44:07 +0000573What's New in Python 2.7 beta 1?
574================================
575
Benjamin Petersonfbac6c12010-04-10 16:22:05 +0000576*Release date: 2010-04-10*
Benjamin Peterson5da7e7c2010-03-06 22:44:07 +0000577
578Core and Builtins
579-----------------
580
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000581- Issue #7301: Add environment variable $PYTHONWARNINGS.
582
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000583- Issue #8329: Don't return the same lists from select.select when no fds are
584 changed.
585
Georg Brandlfee0f442010-05-22 21:26:21 +0000586- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000587 on 64-bit machines. The shift count for either left or right shift is
588 permitted to be up to sys.maxsize.
589
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000590- Ensure that tokenization of identifiers is not affected by locale.
591
Georg Brandlfee0f442010-05-22 21:26:21 +0000592- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +0000593
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000594- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
595
Georg Brandlfee0f442010-05-22 21:26:21 +0000596- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
597 with a non-empty format string. This is an effort to future-proof user
598 code. If a derived class does not currently implement __format__ but later
599 adds its own __format__, it would most likely break user code that had
600 supplied a format string. This will be changed to a DeprecationWaring in
601 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000602
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000603- Issue #8268: Old-style classes (not just instances) now support weak

Benjamin Peterson96545892010-03-21 20:21:00 +0000611- Issue #6474: Make error message from passing an inadequate number of keyword
612 arguments to a function correct.
613
Benjamin Peterson0dee9c12010-03-17 20:41:42 +0000614- Issue #8164: Don't allow lambda functions to have a docstring.

627
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000628- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000629 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
630 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000631
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000632- Issue #8310: Allow dis to examine new style classes.
633
Georg Brandlfee0f442010-05-22 21:26:21 +0000634- Issue #8257: The Decimal construct now accepts a float instance directly,
635 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000636
637 >>> Decimal(1.1)
638 Decimal('1.100000000000000088817841970012523233890533447265625')
639
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000640- collections.Counter() now supports a subtract() method.
641
Georg Brandlfee0f442010-05-22 21:26:21 +0000642- The functools module now has a total_ordering() class decorator to simplify
643 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000644
Georg Brandlfee0f442010-05-22 21:26:21 +0000645- The functools module also adds cmp_to_key() as a tool to transition old-style
646 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +0000647
Georg Brandlfee0f442010-05-22 21:26:21 +0000648- Issue #8294: The Fraction constructor now accepts Decimal and float instances
649 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000650
Georg Brandlfee0f442010-05-22 21:26:21 +0000651- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
652 InvalidOperation instead of returning False. (Comparisons involving a quiet
653 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
654 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000655
Georg Brandlfee0f442010-05-22 21:26:21 +0000656- Issue #2531: Comparison operations between floats and Decimal instances now
657 return a result based on the numeric values of the operands; previously they
658 returned an arbitrary result based on the relative ordering of id(float) and
659 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000660
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000661- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000662 argument `-` which tells it to read files to compile from stdin. Each line is
663 read on demand and the named file is compiled immediately. (Original patch by
664 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000665
Georg Brandlfee0f442010-05-22 21:26:21 +0000666- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +0000669- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
670 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +0000671 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +0000672
Georg Brandlfee0f442010-05-22 21:26:21 +0000673- Comparisons using one of <, <=, >, >= between a complex instance and a
674 Fractions instance now raise TypeError instead of returning True/False. This
675 makes Fraction <=> complex comparisons consistent with int <=> complex, float
676 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +0000677

686
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000687- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +0000688 didn't support chflags() (for example ZFS under FreeBSD). The error is now
689 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000690
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000691- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
692 deprecated.
693
Georg Brandlfee0f442010-05-22 21:26:21 +0000694- Issue #7860: platform.uname now reports the correct 'machine' type when Python
695 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +0000696

Antoine Pitroueee91cd2010-03-26 19:27:16 +0000707- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
708 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
709 reads and writes are always retried by OpenSSL itself.

Vinay Sajipecfa08f2010-03-12 09:16:10 +0000731- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +0000732 for ``TimedRotatingFileHandler`` by using the modification time of an existing
733 log file to compute the next rollover time. If the log file does not exist,
734 the current time is used as the basis for the computation.

Georg Brandlba83f822010-03-14 09:50:54 +0000744- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
745 a base64 transfer-encoded payload *after* decoding it; it no longer does.
746 This is a behavior change, so email's minor version number is now bumped, to

Georg Brandlba83f822010-03-14 09:50:54 +0000780- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
781 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
782 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +0000783 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
784 inconsistent: __int__ was used for some integer codes but not for others, and
785 the set of integer codes for which it was used differed between native packing
786 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00001033- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
1034 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1035 returning NULL. The macro now returns a statically allocated empty string
1036 instead.

1186-----------------
1187
Georg Brandlba83f822010-03-14 09:50:54 +00001188- The ``__complex__()`` method is now looked up on the class of instances to
1189 make it consistent with other special methods.

1193
Mark Dickinson1b34d252010-01-01 17:27:30 +00001194- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001195 DeprecationWarning when passed a float argument where an integer was expected.
1196 These functions and methods now raise TypeError instead. The majority of the
1197 effects of this change are in the extension modules, but some core functions
1198 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1199 and many unicode/str methods.

1213 of integers: the result of a/b is now correctly rounded for ints a and b (at
1214 least on IEEE 754 platforms), and in particular does not depend on the
1215 internal representation of a long.

1223
Georg Brandlba83f822010-03-14 09:50:54 +00001224 These executables now work properly with the arch(1) command: ``arch -ppc

1366 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001367
Georg Brandlba83f822010-03-14 09:50:54 +00001368- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1369 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001370
Georg Brandlba83f822010-03-14 09:50:54 +00001371- Remove restrictions on precision when formatting floats. E.g., "%.120g" %

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001381
Georg Brandlba83f822010-03-14 09:50:54 +00001382- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1383 decimal string that's guaranteed to round back to x under correct rounding
1384 (with round-half-to-even rounding mode). Previously it gave a string based on
1385 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1386 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1387 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001388
Georg Brandlba83f822010-03-14 09:50:54 +00001389- Issue #7117: On almost all platforms: float-to-string and string-to-float
1390 conversions within Python are now correctly rounded. Places these conversions
1391 occur include: str for floats and complex numbers; the float and complex
1392 constructors; old-style and new-style numeric formatting; serialization and
1393 deserialization of floats and complex numbers using marshal, pickle and json;
1394 parsing of float and imaginary literals in Python code; Decimal-to-float
1395 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001396
Georg Brandlba83f822010-03-14 09:50:54 +00001397 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1398 providing correctly-rounded strtod and dtoa C functions. This code is
1399 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1400 the C compiler. There may be a small number of platforms on which correct
1401 operation of this code cannot be guaranteed, so the code is not used: notably,
1402 this applies to platforms where the C double format is not IEEE 754 binary64,
1403 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1404 and Python's configure script is unable to determine how to change the FPU
1405 precision. On these platforms conversions use the platform strtod and dtoa,
1406 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001407
Georg Brandlba83f822010-03-14 09:50:54 +00001408- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1409 uses the correctly-rounded string <-> float conversions described above (when
1410 available), and so produces correctly rounded results that will display nicely
1411 under the float repr. There are two related small changes: (1) round now
1412 accepts any class with an ``__index__()`` method for its second argument (but
1413 no longer accepts floats for the second argument), and (2) an excessively
1414 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1415 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00001557
Georg Brandlba83f822010-03-14 09:50:54 +00001558 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1559 (2) parsing of strings representing infinities and nans was locale aware; and
1560 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001562- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1563 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1564 but with at least one decimal point and with a default precision
1565 of 12. Previously, the behavior the same but with a default precision of 6.
1566 This more closely matches ``str()``, and reduces surprises when adding
1567 alignment flags to the empty presentation type. This also affects the new
1568 complex.__format__ in the same way.
1569
1570- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
1571 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00001633 untrackable objects are not tracked by the garbage collector. This can reduce

1642 internal representation of integers, for performance reasons. Base 2**30 is
1643 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandlba83f822010-03-14 09:50:54 +00001746- Issue #4597: Fixed exception handling when the __exit__ function of a context
1747 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00001748
Georg Brandlba83f822010-03-14 09:50:54 +00001749- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.

Georg Brandlba83f822010-03-14 09:50:54 +00001751- Issue #4445: Replace ``sizeof(PyStringObject)`` with
1752 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1753 instances. On a typical machine this saves 3 bytes of memory (on average) per
1754 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00001756- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1757 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1758 instead of throwing a MemoryError.
1759
Georg Brandlba83f822010-03-14 09:50:54 +00001760- Issue #3689: The list reversed iterator now supports __length_hint__ instead
1761 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00001762
Benjamin Petersonc078f922008-11-21 22:27:24 +00001763- Issue #4367: Python would segfault during compiling when the unicodedata
1764 module couldn't be imported and \N escapes were present.
1765
Georg Brandlba83f822010-03-14 09:50:54 +00001766- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1767 file objects with closefd=False. The file descriptor is still kept open but
1768 the file object behaves like a closed file. The ``FileIO`` object also got a
1769 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00001770
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00001771- Issue #4348: Some bytearray methods returned that didn't cause any change to
1772 the bytearray, returned the same bytearray instead of a copy.
1773
Georg Brandlba83f822010-03-14 09:50:54 +00001774- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

1777
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00001778- Issue #4048: The parser module now correctly validates relative imports.
1779
Benjamin Petersondcee09d2008-10-31 02:16:05 +00001780- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1781 exec statement.
1782
Georg Brandlba83f822010-03-14 09:50:54 +00001783- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
1784 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00001785
Benjamin Petersonbdca9422008-10-26 20:21:13 +00001786- Issue #4209: Enabling unicode_literals and the print_function in the same
1787 __future__ import didn't work.
1788
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001789- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00001790 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001791
Georg Brandlba83f822010-03-14 09:50:54 +00001792- On windows, ``os.chdir()`` given unicode was not working if
1793 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1794 this code path is really executed because I cannot move to such directory on
1795 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00001796
Georg Brandlba83f822010-03-14 09:50:54 +00001797- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1798 element is temporarily replaced with an equivalent frozenset. But the
1799 eventual KeyError would always report the empty ``frozenset()`` as the missing
1800 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00001801
Georg Brandlba83f822010-03-14 09:50:54 +00001802- Issue #4509: Various issues surrounding resize of bytearray objects to which
1803 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00001804
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00001805- Issue #4748: Lambda generators no longer return a value.

1808
Gregory P. Smithae91d092009-03-02 05:13:57 +00001809- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
1810
Georg Brandlba83f822010-03-14 09:50:54 +00001811- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
1812 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00001813
Matthias Klose91a3b9e2009-04-05 21:19:13 +00001814- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1815 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00001816
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00001817- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
1818 returned them on 64bit platforms.
1819
Walter Dörwalded960ac2009-05-03 22:36:33 +00001820- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1821 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1822 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1823 of using the replace error handler in PyUnicode_DecodeUTF8().
1824
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001825- Issue #3739: The unicode-internal encoder now reports the number of characters
1826 consumed like any other encoder (instead of the number of bytes).
1827
Georg Brandlba83f822010-03-14 09:50:54 +00001828- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1829 allocator will be automatically disabled when running under Valgrind. This
1830 gives improved memory leak detection when running under Valgrind, while taking
1831 advantage of pymalloc at other times.

Tarek Ziadéa5076a22009-11-29 22:20:30 +00001856- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
1857 ownership when the group is not forced, because the group may be different
1858 from the user's group and inherit from its container when the test is run.

Georg Brandlba83f822010-03-14 09:50:54 +00001900- Issue #6816: runpy now provides a run_path function that allows Python code to
1901 execute file paths that refer to source or compiled Python files as well as
1902 zipfiles, directories and other valid sys.path entries that contain a
Nick Coghlan49868cb2009-11-15 07:30:34 +00001903 __main__.py file. This allows applications that run other Python scripts to
1904 support the same flexibility as the CPython command line itself.
1905
Georg Brandlba83f822010-03-14 09:50:54 +00001906- Issue #7318: multiprocessing now uses a timeout when it fails to establish a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003196- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3197
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003198- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3199 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3200 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3201 ``printf`` function, whereas PyString_FromFormat has an independent
3202 implementation and uses "%zd" on all platforms for size_t values.
3203 This makes a difference on win64, where ``printf`` needs "%Id" to display
3204 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00003206- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3210 object; previously an int would be returned for small values. the __long__
3211 method is allowed to return either an int or a long, but the behaviour of
3212 float objects should not change to respect backward compatibility.
3213
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003214- Issue #3751: str.rpartition would perform a left-partition when called with
3215 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00003220 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003221 was correctly parsed but parsing of subsequent arguments failed.
3222
Vinay Sajip35e3b032008-09-01 14:33:59 +00003223- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003224 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3225 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3226 when given a tuple of classes as second argument, were looking up
3227 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3228 type object.
3229
Neal Norwitz18aa3882008-08-24 05:04:52 +00003230- Fix crashes on memory allocation failure found with failmalloc.

3299 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3300 for catch_warnings() also led to an improvement in the raising of a

3373-----------------
3374
Guido van Rossumf8402962008-08-20 15:01:50 +00003375- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3376 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3377 extensions do not automatically benefit from the class attribute
3378 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3379 to their tp_flags field if they care. This is a backwards
3380 compatibility feature; in 3.0, all types will use the cache by
3381 default.
3382
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003383- Keyword arguments can now follow starred arguments. (``f(a, *args,
3384 keyword=23)`` is now valid syntax.)
3385
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003386- ctypes function pointers that are COM methods have a boolean True
3387 value again.
3388
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003389- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3390 by denying s# to parse objects that have a releasebuffer procedure,
3391 and introducing s*.
3392
Georg Brandl1e13ea92008-08-11 09:07:59 +00003393- Issue #3537: Fix an assertion failure when an empty but presized dict
3394 object was stored in the freelist.

Mark Dickinsonb6467572008-08-04 21:30:09 +00003396- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3397 ValueError consistently across platforms.
3398
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003399- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3400 (64bit Unix, for example), unichr() would truncate its argument and return
3401 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3402
Neal Norwitze7d8be82008-07-31 17:17:14 +00003403- Apply security patches from Apple.
3404
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003405- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

Antoine Pitrou92f82162008-07-25 22:22:08 +00003408- Issue #1819: function calls with several named parameters are now on
3409 average 35% faster (as measured by pybench).
3410
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003411- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3412 the python debugger steps into a class statement: the free variables (local
3413 variables defined in an outer scope) would be deleted from the outer scope.
3414
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003415- Issue #2620: Overflow checking when allocating or reallocating memory
3416 was not always being done properly in some python types and extension
3417 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3418 all been updated to perform better checks and places in the code that
3419 would previously leak memory on the error path when such an allocation
3420 failed have been fixed.

3426
Benjamin Petersone977ad42008-08-20 01:42:01 +00003427- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3428 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3429
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003430- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3431 version reported by these tools does not necessarily follow the python
3432 version numbering scheme, so the module is less strict when parsing it.
3433
Nick Coghlanf70385a2008-08-18 12:42:46 +00003434- Issue #2235: Added Py3k warnings for types which will become unhashable
3435 under the stricter __hash__ inheritance rules in 3.0. Several types
3436 which did not meet the rules for hash invariants and were already
3437 unhashable in 3.0 have now been explicitly flagged as unhashable in
3438 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3439 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3440
Brett Cannon88f801d2008-08-18 00:46:22 +00003441- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3442 imported into the module but exposed as part of the module's API.
3443
Brett Cannon7b96f072008-08-18 00:41:11 +00003444- Remove an unneeded import of abc.ABCMeta from 'inspect'.

Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003450- Issue #3575: Incremental decoder's decode function now takes bytearray
3451 by using 's*' instead of 't#'.
3452
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003453- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003454 fails unicode conversion on 2nd parameter. (windows only)
3455
Facundo Batista94f243a2008-08-17 03:38:39 +00003456- Issue 2464. urllib2 now supports a malformation in the URL received
3457 in a redirect.

3463 after a 302 response in the case of not going through a proxy.
3464
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003465- Issue #2676: in the email package, content-type parsing was hanging on
3466 pathological input because of quadratic or exponential behaviour of a
3467 regular expression.
3468
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003469- Issue #3476: binary buffered reading through the new "io" library is now
3470 thread-safe.
3471
Brett Cannonbf3157b2008-08-14 05:00:03 +00003472- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3473 since mimetools itself is deprecated. Because modules are cached, all
3474 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3475
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003476- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00003478- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3479 menu entries were not deleted.
3480
Brett Cannon83e81842008-08-09 23:30:55 +00003481- Copied the implementation of reduce() to _functools.reduce() to have a
3482 version that did not raise a DeprecationWarning under -3.
3483
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003484- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3485 a MemoryError rather than silently stop the iteration.
3486
Guido van Rossum59ce9012008-08-09 14:55:34 +00003487- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3488 to _sre.compile() will now be rejected. This should not affect anybody
3489 since the re.compile() function never generates invalid re-bytecode.
3490
Skip Montanaroa032bf42008-08-08 22:52:51 +00003491- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3492 upon first access it can be automatically initialized from the csv file if
3493 it wasn't initialized during instantiation.
3494
Brett Cannon3aa2a492008-08-06 22:28:09 +00003495- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3496 the reload() built-in has been removed.
3497
Brett Cannon7e30b672008-08-04 21:52:25 +00003498- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003499 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3507 raised an AttributeError.
3508
Benjamin Peterson01a24322008-07-28 23:35:27 +00003509- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003510 asking for a specific length. This problem only affected files opened
3511 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003512

3535
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003536- Issue #3394: zipfile.writestr sets external attributes when passed a
3537 file name rather than a ZipInfo instance, so files are extracted with
3538 mode 0600 rather than 000 under Unix.
3539
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003540- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3541 argument in python 2.5, this broke code that subclassed Popen to include its
3542 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3550-------------
3551
Nick Coghlan6e8fef02008-08-18 13:14:22 +00003552- Issue #2235: the C API function PyObject_HashNotImplemented and its
3553 interaction with the tp_hash slot (added in 2.6b2) are now documented
3554
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003555- Issue #643841: The language reference now provides more detailed
3556 coverage of the lookup process for special methods. The disclaimers
3557 regarding lack of coverage of new-style classes have also been
3558 removed, since the coverage is now fairly reasonable.

3562================================
3563
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003564*Release date: 17-Jul-2008*
3565
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003566Core and Builtins
3567-----------------
3568
Georg Brandl3e483f62008-07-16 22:57:41 +00003569- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3570 its methods now allow for items objects that can be converted to
3571 an integer using operator.index().
3572
Mark Dickinson64b7e502008-07-16 09:40:03 +00003573- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3574 produced a ValueError instead of giving the correct float.
3575
Eric Smitha5fa5a22008-07-16 00:11:49 +00003576- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3577 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3578
Mark Dickinson7103aa42008-07-15 19:08:33 +00003579- Issue #3008: the float type has a new instance method 'float.hex'
3580 and a new class method 'float.fromhex' to convert floating-point
3581 numbers to and from hexadecimal strings, respectively.
3582
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003583- Issue #2235: __hash__ is once again inherited by default. To allow
3584 collections.Hashable to remain meaningful in the presence of the
3585 default hash implementation (object.__hash__), it is now possible
3586 to explicit block inheritance of hash by setting __hash__=None at
3587 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3588 level.
3589
Nick Coghlanb028f502008-07-13 14:52:36 +00003590- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3591 the parent module cannot be found while performing an absolute import.
3592 This means that an incorrectly defined __package__ attribute will
3593 now only prevent relative imports in that module rather than causing
3594 all imports from that module to fail.
3595
Nick Coghlan14ff9942008-07-08 14:21:42 +00003596- Issue #2517: Allow unicode messages in Exceptions again by correctly
3597 bypassing the instance dictionary when looking up __unicode__ on
3598 new-style classes.
3599
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003600- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3601 set to a custom object whose write() method happens to install
3602 another file in sys.stdout.
3603
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003604- Issue #3088: Corrected a race condition in classes derived from
3605 threading.local: the first member set by a thread could be saved in
3606 another thread's dictionary.
3607
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003608- Issue #3004: Minor change to slice.indices(): the start and stop
3609 arguments are now treated identically, making the behaviour easier
3610 to describe and understand. For example, slice(None, -10,
3611 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3612 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3613 10, -1).
3614
Georg Brandl278fc502008-07-19 12:46:12 +00003615- Issue #3219: Calling a function with repeated keyword arguments,
3616 f(a=2, a=23), would not cause a syntax error. This was a regression
3617 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003618
Georg Brandl278fc502008-07-19 12:46:12 +00003619- Issue #2862: Make int and float freelist management consistent with
3620 other freelists. Changes their CompactFreeList apis into
3621 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00003622

3624-------
3625
Thomas Heller57adf222008-08-14 19:10:48 +00003626- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3627 api functions without holding the GIL, which could lead to a fatal
3628 error when they failed.
3629
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003630- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00003638- Issue #3125: Remove copy_reg in multiprocessing and replace it with
3639 ForkingPickler.register() to resolve conflict with ctypes.
3640
Vinay Sajip51e65192008-07-18 09:01:10 +00003641- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00003642
Thomas Heller880f5292008-07-15 19:39:38 +00003643- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3644 a valid dlerror() message.
3645
Thomas Heller2bad6572008-07-15 17:19:50 +00003646- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3647 incomplete structure was created.
3648
Brett Cannon3d0b9f02008-07-13 01:15:07 +00003649- Issue #3339: dummy_thread.acquire() should not return None.
3650
Raymond Hettingerb01713e2008-07-10 14:34:57 +00003651- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
3652
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003653- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003654
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003655- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3656 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003657 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003658 content-length. The problem had been corrected in the 2.4 branch, but never
3659 merged into trunk.
3660
Georg Brandle78fbcc2008-07-05 10:13:36 +00003661- Issue #2663: add filtering capability to shutil.copytree().

3667- Issue #1746: Correct handling of zipfile archive comments (previously
3668 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00003669 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00003670
Vinay Sajip51e65192008-07-18 09:01:10 +00003671- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003672 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00003673
Nick Coghlanc060b0e2008-07-02 13:09:19 +00003674- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3675 handling is now the same as that of other special attributes like __name__).
3676
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003677- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
3678 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00004067 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004068
4069 This is controlled by the configure argument ``--with-universal-archs``:
4070
4071 - ``--with-universal-archs=all``: install 4-way universal
4072
4073 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4074
4075 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4076
4077 This option should be used in combination with ``--enable-universalsdk=``.
4078
4079 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00004129- Issue #1631171: Re-implement the 'warnings' module in C (the
4130 original Python code has been kept as backup). This will allow for
4131 using the 'warning's machinery in such places as the parser where
4132 use of pure Python code is not possible. Both the ``showarning()``
4133 and ``formatwarning()`` gain an optional 'line' argument which is
4134 not called by default for backwards-compatibility reasons. Setting
4135 ``warnings.showwarning()`` to an implementation that lacks support
4136 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004199- Issue #2550: The approach used by client/server code for obtaining
4200 ports to listen on in network-oriented tests has been refined in an
4201 effort to facilitate running multiple instances of the entire
4202 regression test suite in parallel without issue.
4203 test_support.bind_port() has been fixed such that it will always
4204 return a unique port -- which wasn't always the case with the
4205 previous implementation, especially if socket options had been set
4206 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4207 new implementation of bind_port() will actually raise an exception
4208 if it is passed an AF_INET/SOCK_STREAM socket with either the
4209 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4210 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4211 the socket it's been passed. This currently only applies to
4212 Windows. This option prevents any other sockets from binding to the
4213 host/port we've bound to, thus removing the possibility of the
4214 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4215 when a second SOCK_STREAM socket binds and accepts to a host/port
4216 that's already been bound by another socket. The optional preferred
4217 port parameter to bind_port() has been removed. Under no
4218 circumstances should tests be hard coding ports!
4219
4220 test_support.find_unused_port() has also been introduced, which will
4221 pass a temporary socket object to bind_port() in order to obtain an
4222 unused port. The temporary socket object is then closed and
4223 deleted, and the port is returned. This method should only be used
4224 for obtaining an unused port in order to pass to an external program
4225 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4226 a parameter to a server-oriented class that doesn't give you direct
4227 access to the underlying socket used.
4228
4229 Finally, test_support.HOST has been introduced, which should be used
4230 for the host argument of any relevant socket calls (i.e. bind and
4231 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004232
4233 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004234 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

4236 test_asynchat and test_socket_ssl.
4237
Georg Brandl3ee81df2008-05-17 18:14:43 +00004238 It is now possible for multiple instances of the regression test
4239 suite to run in parallel without issue.

4507
Fred Drakea8ee94b2008-03-01 02:45:07 +00004508- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004509 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004510
Georg Brandlad61bc82008-02-23 15:11:18 +00004511- Issue #2067: file.__exit__() now calls subclasses' close() method.
4512
4513- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004514
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004515- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004516 issue 215555 for a discussion.
4517
Eric Smitha73fbe72008-02-23 03:09:44 +00004518- Added the future_builtins module, which contains hex() and oct().
4519 These are the PEP 3127 version of these functions, designed to be
4520 compatible with the hex() and oct() builtins from Python 3.0. They
4521 differ slightly in their output formats from the existing, unchanged
4522 Python 2.6 builtins. The expected usage of the future_builtins
4523 module is:
4524 from future_builtins import hex, oct
4525
Eric Smith7ef40bf2008-02-20 23:34:22 +00004526- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4527 exponents for exponents with absolute value < 100. Follows C99
4528 standard. This is a change on Windows, which would use 3 digits.
4529 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4530 so that any alterations it does to the resulting string will be
4531 available in stringlib/formatter.h (for float.__format__).
4532
Eric Smith5a3c1352008-02-19 13:21:56 +00004533- Implemented PEP 3101, Advanced String Formatting. This adds a new
4534 builtin format(); a format() method for str and unicode; a
4535 __format__() method to object, str, unicode, int, long, float, and
4536 datetime; the class string.Formatter; and the C API
4537 PyObject_Format().
4538
Georg Brandl3ee81df2008-05-17 18:14:43 +00004539- Fixed several potential crashes, all caused by specially crafted
4540 __del__ methods exploiting objects in temporarily inconsistent
4541 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004542
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004543- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004544 prevent a possible crash: an Abstract Base Class would try to access
4545 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004546
Georg Brandl3ee81df2008-05-17 18:14:43 +00004547- Fixed repr() and str() of complex numbers with infinity or nan as
4548 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004549
Georg Brandl3ee81df2008-05-17 18:14:43 +00004550- Clear all free lists during a gc.collect() of the highest generation
4551 in order to allow pymalloc to free more arenas. Python may give back
4552 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004553
Georg Brandl3ee81df2008-05-17 18:14:43 +00004554- Issue #2045: Fix an infinite recursion triggered when printing a
4555 subclass of collections.defaultdict, if its default_factory is set
4556 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004557
Christian Heimesf75dbef2008-02-08 00:11:31 +00004558- Fixed a minor memory leak in dictobject.c. The content of the free
4559 list was not freed on interpreter shutdown.
4560
Georg Brandl21e99f42010-03-07 15:23:59 +00004561- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004562 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004563
Georg Brandl3ee81df2008-05-17 18:14:43 +00004564- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4565 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004566 to compact the internal free lists of pre-allocted ints and floats.
4567
Georg Brandl3ee81df2008-05-17 18:14:43 +00004568- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4569 calls. Python expected the return type int but the fork familie
4570 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004571
Georg Brandl3ee81df2008-05-17 18:14:43 +00004572- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4573 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004574
Georg Brandl3ee81df2008-05-17 18:14:43 +00004575- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4576 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004577
Georg Brandl3ee81df2008-05-17 18:14:43 +00004578- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4579 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004580
Georg Brandl3ee81df2008-05-17 18:14:43 +00004581- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4582 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004583
Georg Brandl3ee81df2008-05-17 18:14:43 +00004584- Patch #1473257: generator objects gain a gi_code attribute. This is
4585 the same object as the func_code attribute of the function that
4586 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004587
Georg Brandl3ee81df2008-05-17 18:14:43 +00004588- Issue #1920: "while 0" statements were completely removed by the
4589 compiler, even in the presence of an "else" clause, which is
4590 supposed to be run when the condition is false. Now the compiler
4591 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004592
Guido van Rossumeead05f2008-01-24 18:21:02 +00004593- A few crashers fixed: weakref_in_del.py (issue #1377858);
4594 loosing_dict_ref.py (issue #1303614, test67.py);
4595 borrowed_ref_[34].py (not in tracker).
4596
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004597- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004598 suppressed while an extension is loaded by calling SetErrorMode in
4599 dynload_win.c. The error is still reported properly.
4600
Georg Brandl3ee81df2008-05-17 18:14:43 +00004601- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004602 several extension methods and modules do not work without unicode
4603 support.
4604
Georg Brandl26543b12008-01-21 18:36:51 +00004605- Issue #1882: when compiling code from a string, encoding cookies in the
4606 second line of code were not always recognized correctly.
4607
Georg Brandl14404b62008-01-19 19:27:05 +00004608- Issue #1679: "0x" was taken as a valid integer literal.
4609
Georg Brandl6caad7d2008-01-26 14:19:22 +00004610- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004611 added.
4612
Christian Heimesc94e2b52008-01-14 04:13:37 +00004613- sys.float_info / PyFloat_GetInfo: The floating point information
4614 object was converted from a dict to a specialized structseq object.
4615
Georg Brandl3ee81df2008-05-17 18:14:43 +00004616- Patch #1816: Added sys.flags structseq. It exposes the status of
4617 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004618
Georg Brandl3ee81df2008-05-17 18:14:43 +00004619- Objects/structseq.c: Implemented new structseq representation. The
4620 patch makes structseqs (e.g. the return value of os.stat) more
4621 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004622
Georg Brandl3ee81df2008-05-17 18:14:43 +00004623- Patch #1700288: added a type attribute cache that caches method
4624 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004625
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004626- Bug #1776: __import__() no longer accepts filenames on any platform.
4627 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004628
Georg Brandlaed6c662008-01-07 17:25:53 +00004629- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4630
Georg Brandl3ee81df2008-05-17 18:14:43 +00004631- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4632 envvar and sys.dont_write_bytecode attribute. All these can be set
4633 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004634
Georg Brandl3ee81df2008-05-17 18:14:43 +00004635- Improve some exception messages when Windows fails to load an
4636 extension module. Now we get for example '%1 is not a valid Win32
4637 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004638
Georg Brandl3ee81df2008-05-17 18:14:43 +00004639- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004641- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4642 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004643
Christian Heimes0a8143f2007-12-18 23:22:54 +00004644- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004645 and INF. float("nan"), float("inf") and float("-inf") now work on
4646 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004647
Georg Brandl3ee81df2008-05-17 18:14:43 +00004648- Compiler now generates simpler and faster code for dictionary
4649 literals. The oparg for BUILD_MAP now indicates an estimated
4650 dictionary size. There is a new opcode, STORE_MAP, for adding
4651 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004652
Georg Brandl3ee81df2008-05-17 18:14:43 +00004653- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004658- Issue #1538: Avoid copying string in split/rsplit if the split char
4659 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004660
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004661- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004662 SystemError.
4663
Nick Coghlanef01d822007-12-03 12:55:17 +00004664- PEP 366: Allow explicit relative imports when executing modules

4666 __package__ attribute.
4667
Georg Brandl3ee81df2008-05-17 18:14:43 +00004668- Issue #1402: Fix a crash on exit, when another thread is still
4669 running, and if the deallocation of its frames somehow calls the
4670 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004671

4681 file can now be directly executed by passing their name to the
4682 interpreter. The directory/zipfile is automatically inserted as the
4683 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004684
Georg Brandl3ee81df2008-05-17 18:14:43 +00004685- Issue #1265: Fix a problem with sys.settrace, if the tracing
4686 function uses a generator expression when at the same time the
4687 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004688
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004689- sets and frozensets now have an isdisjoint() method.
4690
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004691- optimize the performance of builtin.sum().
4692
Neal Norwitz44f326e2007-10-05 05:29:17 +00004693- Fix warnings found by the new version of the Coverity checker.
4694
Georg Brandl21e99f42010-03-07 15:23:59 +00004695- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004696 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4697 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004698
Georg Brandl3ee81df2008-05-17 18:14:43 +00004699- Issue #1686386: Tuple's tp_repr did not take into account the
4700 possibility of having a self-referential tuple, which is possible
4701 from C code. Nor did object's tp_str consider that a type's tp_str
4702 could do something that could lead to an inifinite recursion.
4703 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4704 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004705
Georg Brandl3ee81df2008-05-17 18:14:43 +00004706- Issue #1164: It was possible to trigger deadlock when using the
4707 'print' statement to write to a file since the GIL was not released
4708 as needed. Now PyObject_Print() does the right thing along with
4709 various tp_print implementations of the built-in types and those in
4710 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004711
Georg Brandl3ee81df2008-05-17 18:14:43 +00004712- Issue #1147: Exceptions were directly allowing string exceptions in
4713 their throw() method even though string exceptions no longer
4714 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004715
Georg Brandl3ee81df2008-05-17 18:14:43 +00004716- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00004719- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004720 PyObject_Call() never calling back out to Python code to trigger
4721 recursion depth updates/checks. Required the creation of a static
4722 RuntimeError instance in case normalizing an exception put the
4723 recursion check value past its limit. Fixes crashers
4724 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004725
Georg Brandl3ee81df2008-05-17 18:14:43 +00004726- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004739- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004740 __*__ attributes. (Some already existed, e.g., __doc__ and
4741 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004742
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004743- Add -3 option to the interpreter to warn about features that are
4744 deprecated and will be changed/removed in Python 3.0.
4745

Collin Winter62903052007-05-18 23:11:24 +00004749- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004750 "except E as target:". This is to provide forwards compatibility
4751 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004752
Brett Cannon229cee22007-05-05 01:34:02 +00004753- Deprecate BaseException.message as per PEP 352.
4754
Georg Brandl3ee81df2008-05-17 18:14:43 +00004755- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004756 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004757
Vinay Sajip8549ce32007-05-06 17:53:37 +00004758- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004759 setting a plain string, ie don't expand to single letter identifiers.
4760
Raymond Hettinger13936692007-04-11 18:40:58 +00004761- Request #1191699: Slices can now be pickled.

Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004763- Request #1193128: str.translate() now allows a None argument for
4764 translations that only remove characters without re-mapping the
4765 remaining characters.
4766
Georg Brandl5cb76c12007-03-21 09:00:39 +00004767- Patch #1682205: a TypeError while unpacking an iterable is no longer

4771
Guido van Rossum143b5642007-03-23 04:58:42 +00004772- Bug #1683368: The object.__init__() and object.__new__() methods are
4773 now stricter in rejecting excess arguments. The only time when
4774 either allows excess arguments is when it is not overridden and the
4775 other one is. For backwards compatibility, when both are
4776 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004777 warning later). Also, type.__init__() insists on the same signature
4778 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004779
Georg Brandl3ee81df2008-05-17 18:14:43 +00004780- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4781 object to complex using its __complex__() method before falling back
4782 to the __float__() method. Therefore, the functions in the cmath
4783 module now can operate on objects that define a __complex__()
4784 method.

4788 same slot names.

4801
Georg Brandl7b9c5552007-03-12 14:30:05 +00004802- Bug #1678647: write a newline after printing an exception in any
4803 case, even when converting the value to a string failed.
4804
Georg Brandl871f1bc2007-03-12 13:17:36 +00004805- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004806 its argument, if it exists. If not, it will work like before. This
4807 allows customizing the output of dir() in the presence of a
4808 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00004810- Patch #922167: Python no longer segfaults when faced with infinitely
4811 self-recursive reload() calls (as reported by bug #742342).

4817 parthensized forms. This means complex(repr(x)) now works instead of
4818 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004819
Georg Brandlaa2321b2007-03-07 00:40:28 +00004820- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004821 makes the filenames the warning module prints much more sensible
4822 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004823

Georg Brandl0fca97a2007-03-05 22:28:08 +00004835- Patch #1674228: when assigning a slice (old-style), check for the
4836 sq_ass_slice instead of the sq_slice slot.
4837
Georg Brandl3ee81df2008-05-17 18:14:43 +00004838- When printing an unraisable error, don't print exceptions. before
4839 the name. This duplicates the behavior whening normally printing
4840 exceptions.

4849 created a weakref on itself during a __del__ call for new-style
4850 classes (classic classes still have the bug).

4891 embedded in the string to convert.
4892
Georg Brandl846f73a2006-10-08 07:11:54 +00004893- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00004941 generator expressions (x for x, in ... ) works again. Fixing this
4942 problem required changing the .pyc magic number. This means that
4943 .pyc files generated before 2.5c2 will be regenerated.

5465 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00005750- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5751 with RFC 3207 and forgets any knowledge obtained from the server not
5752 obtained from the TLS negotiation itself. Patch contributed by Bill
5753 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005754

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005756 that the SMTP.starttls() caller no longer needs to call ehlo()
5757 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005758 does not claim to support starttls. Adds the

5840 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5841 silently miscode subclasses of those types. Now, it raises a
5842 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005843

Georg Brandl3ee81df2008-05-17 18:14:43 +00005858 time so that opening a database previously created with the DB_DUP
5859 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5860 opens. Specifically: dictionary assignment to a DB object will
5861 replace all values for a given key when the database allows
5862 duplicate values. DB users should use DB.put(k, v) when they want
5863 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005864

5870 characters with ASCII value less than 32. Also, it correctly quotes
5871 dots only if they occur on a single line, as opposed to the previous
5872 behavior of quoting dots if they are the second character of any
5873 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005874

6211 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006212
6213- Patch #1720595: add T_BOOL to the range of structmember types.
6214
6215- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
6216 ``PyFloat_GetInfo()`` to the float API.
6217
Georg Brandl3ee81df2008-05-17 18:14:43 +00006218- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6219 of w# format code incorrectly truncated the length to an int, even
6220 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6221 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006222
Georg Brandl3ee81df2008-05-17 18:14:43 +00006223- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
6224 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006226- PEP 3123: Provide forward compatibility with Python 3.0, while
6227 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
6228 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006229
Georg Brandl3ee81df2008-05-17 18:14:43 +00006230- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
6231 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006232
6233- Patch #1733960: Allow T_LONGLONG to accept ints.
6234
6235- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
6236
Christian Heimes000a0742008-01-03 22:16:32 +00006237- Added a new API function ``PyImport_ImportModuleNoBlock``.
6238
Georg Brandl6caad7d2008-01-26 14:19:22 +00006239- Bug #1637022: Prefix AST symbols with _Py_.
6240
6241- Fix some leftovers from the conversion from int to Py_ssize_t
6242 (relevant to strings and sequences of more than 2**31 items).
6243
6244- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6245 outside of pystate.c and should not be necessary.
6246
Georg Brandl3ee81df2008-05-17 18:14:43 +00006247- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6248 absolute imports. In earlier versions they might have used relative
6249 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006250
Georg Brandl3ee81df2008-05-17 18:14:43 +00006251- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6252 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006253
Georg Brandl3ee81df2008-05-17 18:14:43 +00006254- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
6255 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006261- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
6262 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6263 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6264 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006279- Removed the macfs module. It had been deprecated since Python 2.5.
6280 This lead to the deprecation of macostools.touched() as it relied
6281 solely on macfs and was a no-op under OS X.
