Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000216- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
217 start byte and the continuation byte(s) are now considered invalid, instead
218 of the number of bytes specified by the start byte.
219 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
220 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
221 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
222 Previous versions returned a single u'\ufffd'.

231 objects. (1) The comparison could incorrectly return True in some cases
232 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
233 (2) The comparison raised an OverflowError for large integers, leading

Mark Dickinson81336372010-05-30 12:12:25 +0000237- Issue #5211: Implicit coercion for the complex type is now completely

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000577 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
578 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's

599Core and Builtins
600-----------------
601
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000602- Issue #7301: Add environment variable $PYTHONWARNINGS.
603
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000604- Issue #8329: Don't return the same lists from select.select when no fds are
605 changed.
606
Georg Brandlfee0f442010-05-22 21:26:21 +0000607- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000608 on 64-bit machines. The shift count for either left or right shift is
609 permitted to be up to sys.maxsize.
610
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000611- Ensure that tokenization of identifiers is not affected by locale.

Georg Brandlfee0f442010-05-22 21:26:21 +0000613- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +0000614
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000615- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
616
Georg Brandlfee0f442010-05-22 21:26:21 +0000617- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
618 with a non-empty format string. This is an effort to future-proof user
619 code. If a derived class does not currently implement __format__ but later
620 adds its own __format__, it would most likely break user code that had
621 supplied a format string. This will be changed to a DeprecationWaring in
622 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000623
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000624- Issue #8268: Old-style classes (not just instances) now support weak

648
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000649- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000650 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
651 `ssl.OPENSSL_VERSION_NUMBER`.

654
Georg Brandlfee0f442010-05-22 21:26:21 +0000655- Issue #8257: The Decimal construct now accepts a float instance directly,
656 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000657
658 >>> Decimal(1.1)
659 Decimal('1.100000000000000088817841970012523233890533447265625')
660
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000661- collections.Counter() now supports a subtract() method.
662
Georg Brandlfee0f442010-05-22 21:26:21 +0000663- The functools module now has a total_ordering() class decorator to simplify
664 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000665
Georg Brandlfee0f442010-05-22 21:26:21 +0000666- The functools module also adds cmp_to_key() as a tool to transition old-style
667 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +0000668
Georg Brandlfee0f442010-05-22 21:26:21 +0000669- Issue #8294: The Fraction constructor now accepts Decimal and float instances
670 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000671
Georg Brandlfee0f442010-05-22 21:26:21 +0000672- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
673 InvalidOperation instead of returning False. (Comparisons involving a quiet
674 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
675 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000676
Georg Brandlfee0f442010-05-22 21:26:21 +0000677- Issue #2531: Comparison operations between floats and Decimal instances now
678 return a result based on the numeric values of the operands; previously they
679 returned an arbitrary result based on the relative ordering of id(float) and
680 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000681
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000682- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000683 argument `-` which tells it to read files to compile from stdin. Each line is
684 read on demand and the named file is compiled immediately. (Original patch by
685 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000686
Georg Brandlfee0f442010-05-22 21:26:21 +0000687- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +0000690- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
691 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +0000692 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +0000693
Georg Brandlfee0f442010-05-22 21:26:21 +0000694- Comparisons using one of <, <=, >, >= between a complex instance and a
695 Fractions instance now raise TypeError instead of returning True/False. This
696 makes Fraction <=> complex comparisons consistent with int <=> complex, float
697 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +0000698

Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000708- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +0000709 didn't support chflags() (for example ZFS under FreeBSD). The error is now
710 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000711
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000712- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
713 deprecated.

Vinay Sajipecfa08f2010-03-12 09:16:10 +0000752- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +0000753 for ``TimedRotatingFileHandler`` by using the modification time of an existing
754 log file to compute the next rollover time. If the log file does not exist,
755 the current time is used as the basis for the computation.

802 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the

805 inconsistent: __int__ was used for some integer codes but not for others, and
806 the set of integer codes for which it was used differed between native packing
807 and standard packing.)

1207-----------------
1208
Georg Brandlba83f822010-03-14 09:50:54 +00001209- The ``__complex__()`` method is now looked up on the class of instances to
1210 make it consistent with other special methods.

1214
Mark Dickinson1b34d252010-01-01 17:27:30 +00001215- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001216 DeprecationWarning when passed a float argument where an integer was expected.
1217 These functions and methods now raise TypeError instead. The majority of the
1218 effects of this change are in the extension modules, but some core functions
1219 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1220 and many unicode/str methods.

1234 of integers: the result of a/b is now correctly rounded for ints a and b (at
1235 least on IEEE 754 platforms), and in particular does not depend on the
1236 internal representation of a long.

1244
Georg Brandlba83f822010-03-14 09:50:54 +00001245 These executables now work properly with the arch(1) command: ``arch -ppc
1246 python`` will start a universal binary version of python in PPC mode (unlike

1386 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1387 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001388
Georg Brandlba83f822010-03-14 09:50:54 +00001389- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1390 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001391
Georg Brandlba83f822010-03-14 09:50:54 +00001392- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1393 1e-100 used to raise OverflowError, but now gives the requested 120
1394 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001402
Georg Brandlba83f822010-03-14 09:50:54 +00001403- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1404 decimal string that's guaranteed to round back to x under correct rounding
1405 (with round-half-to-even rounding mode). Previously it gave a string based on
1406 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1407 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1408 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001409
Georg Brandlba83f822010-03-14 09:50:54 +00001410- Issue #7117: On almost all platforms: float-to-string and string-to-float
1411 conversions within Python are now correctly rounded. Places these conversions
1412 occur include: str for floats and complex numbers; the float and complex
1413 constructors; old-style and new-style numeric formatting; serialization and
1414 deserialization of floats and complex numbers using marshal, pickle and json;
1415 parsing of float and imaginary literals in Python code; Decimal-to-float
1416 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001417
Georg Brandlba83f822010-03-14 09:50:54 +00001418 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1419 providing correctly-rounded strtod and dtoa C functions. This code is
1420 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1421 the C compiler. There may be a small number of platforms on which correct
1422 operation of this code cannot be guaranteed, so the code is not used: notably,
1423 this applies to platforms where the C double format is not IEEE 754 binary64,
1424 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1425 and Python's configure script is unable to determine how to change the FPU
1426 precision. On these platforms conversions use the platform strtod and dtoa,
1427 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001428
Georg Brandlba83f822010-03-14 09:50:54 +00001429- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1430 uses the correctly-rounded string <-> float conversions described above (when
1431 available), and so produces correctly rounded results that will display nicely
1432 under the float repr. There are two related small changes: (1) round now
1433 accepts any class with an ``__index__()`` method for its second argument (but
1434 no longer accepts floats for the second argument), and (2) an excessively
1435 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1436 raises an exception.

1439
Georg Brandlba83f822010-03-14 09:50:54 +00001440- Fix several issues with ``compile()``. The input can now contain Windows and

Mark Dickinsonb1d45852009-05-11 15:33:08 +00001578
Georg Brandlba83f822010-03-14 09:50:54 +00001579 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1580 (2) parsing of strings representing infinities and nans was locale aware; and
1581 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00001582
Georg Brandlba83f822010-03-14 09:50:54 +00001583- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1584 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1585 but with at least one decimal point and with a default precision
1586 of 12. Previously, the behavior the same but with a default precision of 6.
1587 This more closely matches ``str()``, and reduces surprises when adding
1588 alignment flags to the empty presentation type. This also affects the new
1589 complex.__format__ in the same way.
1590
1591- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
1592 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00001654 untrackable objects are not tracked by the garbage collector. This can reduce

1663 internal representation of integers, for performance reasons. Base 2**30 is
1664 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandl6425a2f2008-12-28 11:54:53 +00001752- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00001753 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00001754
Skip Montanarof205c132008-12-23 03:30:15 +00001755- Added test case to ensure attempts to read from a file opened for writing
1756 fail.
1757
Georg Brandlba83f822010-03-14 09:50:54 +00001758- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
1759 elapsed times, not only when some objects are uncollectable/unreachable.

Georg Brandlba83f822010-03-14 09:50:54 +00001772- Issue #4445: Replace ``sizeof(PyStringObject)`` with
1773 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1774 instances. On a typical machine this saves 3 bytes of memory (on average) per
1775 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00001777- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1778 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1779 instead of throwing a MemoryError.
1780
Georg Brandlba83f822010-03-14 09:50:54 +00001781- Issue #3689: The list reversed iterator now supports __length_hint__ instead
1782 of __len__. Behavior now matches other reversed iterators.

Benjamin Petersonc078f922008-11-21 22:27:24 +00001784- Issue #4367: Python would segfault during compiling when the unicodedata

1786
Georg Brandlba83f822010-03-14 09:50:54 +00001787- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1788 file objects with closefd=False. The file descriptor is still kept open but
1789 the file object behaves like a closed file. The ``FileIO`` object also got a
1790 new readonly attribute ``closefd``.

Benjamin Peterson46cc6d12008-11-19 21:49:09 +00001792- Issue #4348: Some bytearray methods returned that didn't cause any change to
1793 the bytearray, returned the same bytearray instead of a copy.
1794
Georg Brandlba83f822010-03-14 09:50:54 +00001795- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Petersonbdca9422008-10-26 20:21:13 +00001807- Issue #4209: Enabling unicode_literals and the print_function in the same
1808 __future__ import didn't work.
1809
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001810- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00001811 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001812
Georg Brandlba83f822010-03-14 09:50:54 +00001813- On windows, ``os.chdir()`` given unicode was not working if
1814 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1815 this code path is really executed because I cannot move to such directory on
1816 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00001817
Georg Brandlba83f822010-03-14 09:50:54 +00001818- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1819 element is temporarily replaced with an equivalent frozenset. But the
1820 eventual KeyError would always report the empty ``frozenset()`` as the missing
1821 key. Now it correctly refers to the initial element.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +00001838- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
1839 returned them on 64bit platforms.
1840
Walter Dörwalded960ac2009-05-03 22:36:33 +00001841- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1842 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1843 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1844 of using the replace error handler in PyUnicode_DecodeUTF8().
1845
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001846- Issue #3739: The unicode-internal encoder now reports the number of characters
1847 consumed like any other encoder (instead of the number of bytes).
1848
Georg Brandlba83f822010-03-14 09:50:54 +00001849- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1850 allocator will be automatically disabled when running under Valgrind. This
1851 gives improved memory leak detection when running under Valgrind, while taking
1852 advantage of pymalloc at other times.

3019 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3020 neither __int__ nor __long__, TypeError used to be raised (with a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003217- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3218
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003219- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3220 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3221 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3222 ``printf`` function, whereas PyString_FromFormat has an independent
3223 implementation and uses "%zd" on all platforms for size_t values.
3224 This makes a difference on win64, where ``printf`` needs "%Id" to display
3225 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00003227- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3231 object; previously an int would be returned for small values. the __long__
3232 method is allowed to return either an int or a long, but the behaviour of
3233 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003235- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00003241 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003242 was correctly parsed but parsing of subsequent arguments failed.
3243
Vinay Sajip35e3b032008-09-01 14:33:59 +00003244- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003245 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3246 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3247 when given a tuple of classes as second argument, were looking up
3248 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3249 type object.
3250
Neal Norwitz18aa3882008-08-24 05:04:52 +00003251- Fix crashes on memory allocation failure found with failmalloc.

3394-----------------
3395
Guido van Rossumf8402962008-08-20 15:01:50 +00003396- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3397 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3398 extensions do not automatically benefit from the class attribute
3399 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3400 to their tp_flags field if they care. This is a backwards
3401 compatibility feature; in 3.0, all types will use the cache by
3402 default.
3403
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003404- Keyword arguments can now follow starred arguments. (``f(a, *args,

Thomas Heller0ad5ae02008-08-19 19:25:04 +00003407- ctypes function pointers that are COM methods have a boolean True
3408 value again.
3409
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003410- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3411 by denying s# to parse objects that have a releasebuffer procedure,
3412 and introducing s*.

Georg Brandl1e13ea92008-08-11 09:07:59 +00003414- Issue #3537: Fix an assertion failure when an empty but presized dict
3415 object was stored in the freelist.
3416
Mark Dickinsonb6467572008-08-04 21:30:09 +00003417- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3418 ValueError consistently across platforms.
3419
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003420- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3421 (64bit Unix, for example), unichr() would truncate its argument and return
3422 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3423
Neal Norwitze7d8be82008-07-31 17:17:14 +00003424- Apply security patches from Apple.
3425
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003426- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3427 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3428
Antoine Pitrou92f82162008-07-25 22:22:08 +00003429- Issue #1819: function calls with several named parameters are now on
3430 average 35% faster (as measured by pybench).
3431
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003432- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3433 the python debugger steps into a class statement: the free variables (local
3434 variables defined in an outer scope) would be deleted from the outer scope.
3435
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003436- Issue #2620: Overflow checking when allocating or reallocating memory
3437 was not always being done properly in some python types and extension
3438 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3439 all been updated to perform better checks and places in the code that
3440 would previously leak memory on the error path when such an allocation
3441 failed have been fixed.

3447
Benjamin Petersone977ad42008-08-20 01:42:01 +00003448- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3449 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3450
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003451- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3452 version reported by these tools does not necessarily follow the python
3453 version numbering scheme, so the module is less strict when parsing it.
3454
Nick Coghlanf70385a2008-08-18 12:42:46 +00003455- Issue #2235: Added Py3k warnings for types which will become unhashable
3456 under the stricter __hash__ inheritance rules in 3.0. Several types
3457 which did not meet the rules for hash invariants and were already
3458 unhashable in 3.0 have now been explicitly flagged as unhashable in
3459 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3460 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3461
Brett Cannon88f801d2008-08-18 00:46:22 +00003462- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003471- Issue #3575: Incremental decoder's decode function now takes bytearray
3472 by using 's*' instead of 't#'.
3473
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003474- Issue #2222: Fixed reference leak when occurred os.rename()

3484 after a 302 response in the case of not going through a proxy.
3485
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003486- Issue #2676: in the email package, content-type parsing was hanging on
3487 pathological input because of quadratic or exponential behaviour of a
3488 regular expression.
3489
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003490- Issue #3476: binary buffered reading through the new "io" library is now
3491 thread-safe.
3492
Brett Cannonbf3157b2008-08-14 05:00:03 +00003493- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3494 since mimetools itself is deprecated. Because modules are cached, all
3495 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3496
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003497- Issue #3134: shutil referenced undefined WindowsError symbol.

Brett Cannon83e81842008-08-09 23:30:55 +00003502- Copied the implementation of reduce() to _functools.reduce() to have a
3503 version that did not raise a DeprecationWarning under -3.
3504
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003505- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3506 a MemoryError rather than silently stop the iteration.
3507
Guido van Rossum59ce9012008-08-09 14:55:34 +00003508- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3509 to _sre.compile() will now be rejected. This should not affect anybody
3510 since the re.compile() function never generates invalid re-bytecode.
3511
Skip Montanaroa032bf42008-08-08 22:52:51 +00003512- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3513 upon first access it can be automatically initialized from the csv file if
3514 it wasn't initialized during instantiation.
3515
Brett Cannon3aa2a492008-08-06 22:28:09 +00003516- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3517 the reload() built-in has been removed.
3518
Brett Cannon7e30b672008-08-04 21:52:25 +00003519- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003520 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3528 raised an AttributeError.
3529
Benjamin Peterson01a24322008-07-28 23:35:27 +00003530- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003531 asking for a specific length. This problem only affected files opened
3532 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003533

3556
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003557- Issue #3394: zipfile.writestr sets external attributes when passed a
3558 file name rather than a ZipInfo instance, so files are extracted with
3559 mode 0600 rather than 000 under Unix.
3560
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003561- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3562 argument in python 2.5, this broke code that subclassed Popen to include its
3563 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00003573- Issue #2235: the C API function PyObject_HashNotImplemented and its
3574 interaction with the tp_hash slot (added in 2.6b2) are now documented
3575
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003576- Issue #643841: The language reference now provides more detailed
3577 coverage of the lookup process for special methods. The disclaimers
3578 regarding lack of coverage of new-style classes have also been
3579 removed, since the coverage is now fairly reasonable.

3583================================
3584
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003585*Release date: 17-Jul-2008*
3586
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003587Core and Builtins
3588-----------------
3589
Georg Brandl3e483f62008-07-16 22:57:41 +00003590- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3591 its methods now allow for items objects that can be converted to
3592 an integer using operator.index().
3593
Mark Dickinson64b7e502008-07-16 09:40:03 +00003594- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3595 produced a ValueError instead of giving the correct float.
3596
Eric Smitha5fa5a22008-07-16 00:11:49 +00003597- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3598 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3599
Mark Dickinson7103aa42008-07-15 19:08:33 +00003600- Issue #3008: the float type has a new instance method 'float.hex'
3601 and a new class method 'float.fromhex' to convert floating-point
3602 numbers to and from hexadecimal strings, respectively.
3603
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003604- Issue #2235: __hash__ is once again inherited by default. To allow
3605 collections.Hashable to remain meaningful in the presence of the
3606 default hash implementation (object.__hash__), it is now possible
3607 to explicit block inheritance of hash by setting __hash__=None at
3608 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3609 level.
3610
Nick Coghlanb028f502008-07-13 14:52:36 +00003611- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3612 the parent module cannot be found while performing an absolute import.
3613 This means that an incorrectly defined __package__ attribute will
3614 now only prevent relative imports in that module rather than causing
3615 all imports from that module to fail.
3616
Nick Coghlan14ff9942008-07-08 14:21:42 +00003617- Issue #2517: Allow unicode messages in Exceptions again by correctly
3618 bypassing the instance dictionary when looking up __unicode__ on
3619 new-style classes.
3620
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003621- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3622 set to a custom object whose write() method happens to install
3623 another file in sys.stdout.
3624
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003625- Issue #3088: Corrected a race condition in classes derived from
3626 threading.local: the first member set by a thread could be saved in
3627 another thread's dictionary.
3628
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003629- Issue #3004: Minor change to slice.indices(): the start and stop
3630 arguments are now treated identically, making the behaviour easier
3631 to describe and understand. For example, slice(None, -10,
3632 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3633 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3634 10, -1).
3635
Georg Brandl278fc502008-07-19 12:46:12 +00003636- Issue #3219: Calling a function with repeated keyword arguments,
3637 f(a=2, a=23), would not cause a syntax error. This was a regression
3638 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003639
Georg Brandl278fc502008-07-19 12:46:12 +00003640- Issue #2862: Make int and float freelist management consistent with
3641 other freelists. Changes their CompactFreeList apis into
3642 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00003643

3645-------
3646
Thomas Heller57adf222008-08-14 19:10:48 +00003647- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3648 api functions without holding the GIL, which could lead to a fatal
3649 error when they failed.
3650
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003651- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

3660 ForkingPickler.register() to resolve conflict with ctypes.
3661
Vinay Sajip51e65192008-07-18 09:01:10 +00003662- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

3665 a valid dlerror() message.
3666
Thomas Heller2bad6572008-07-15 17:19:50 +00003667- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3668 incomplete structure was created.
3669
Brett Cannon3d0b9f02008-07-13 01:15:07 +00003670- Issue #3339: dummy_thread.acquire() should not return None.

Raymond Hettingerb01713e2008-07-10 14:34:57 +00003672- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
3673
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003674- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003675
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003676- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3677 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003678 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003679 content-length. The problem had been corrected in the 2.4 branch, but never
3680 merged into trunk.
3681
Georg Brandle78fbcc2008-07-05 10:13:36 +00003682- Issue #2663: add filtering capability to shutil.copytree().

Georg Brandl5cc774e2008-06-11 20:28:06 +00004088 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004089
4090 This is controlled by the configure argument ``--with-universal-archs``:
4091
4092 - ``--with-universal-archs=all``: install 4-way universal
4093
4094 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4095
4096 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4097
4098 This option should be used in combination with ``--enable-universalsdk=``.
4099
4100 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 +00004150- Issue #1631171: Re-implement the 'warnings' module in C (the
4151 original Python code has been kept as backup). This will allow for
4152 using the 'warning's machinery in such places as the parser where
4153 use of pure Python code is not possible. Both the ``showarning()``
4154 and ``formatwarning()`` gain an optional 'line' argument which is
4155 not called by default for backwards-compatibility reasons. Setting
4156 ``warnings.showwarning()`` to an implementation that lacks support
4157 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004182- The getpass module has been improved on Unix. It now uses /dev/tty
4183 by default and uses stderr instead of stdout. A GetPassWarning is
4184 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004220- Issue #2550: The approach used by client/server code for obtaining
4221 ports to listen on in network-oriented tests has been refined in an
4222 effort to facilitate running multiple instances of the entire
4223 regression test suite in parallel without issue.
4224 test_support.bind_port() has been fixed such that it will always
4225 return a unique port -- which wasn't always the case with the
4226 previous implementation, especially if socket options had been set
4227 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4228 new implementation of bind_port() will actually raise an exception
4229 if it is passed an AF_INET/SOCK_STREAM socket with either the
4230 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4231 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4232 the socket it's been passed. This currently only applies to
4233 Windows. This option prevents any other sockets from binding to the
4234 host/port we've bound to, thus removing the possibility of the
4235 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4236 when a second SOCK_STREAM socket binds and accepts to a host/port
4237 that's already been bound by another socket. The optional preferred
4238 port parameter to bind_port() has been removed. Under no
4239 circumstances should tests be hard coding ports!
4240
4241 test_support.find_unused_port() has also been introduced, which will
4242 pass a temporary socket object to bind_port() in order to obtain an
4243 unused port. The temporary socket object is then closed and
4244 deleted, and the port is returned. This method should only be used
4245 for obtaining an unused port in order to pass to an external program
4246 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4247 a parameter to a server-oriented class that doesn't give you direct
4248 access to the underlying socket used.
4249
4250 Finally, test_support.HOST has been introduced, which should be used
4251 for the host argument of any relevant socket calls (i.e. bind and
4252 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004253

4526Core and builtins
4527-----------------
4528
Fred Drakea8ee94b2008-03-01 02:45:07 +00004529- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004530 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004531
Georg Brandlad61bc82008-02-23 15:11:18 +00004532- Issue #2067: file.__exit__() now calls subclasses' close() method.
4533
4534- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004535
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004536- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004537 issue 215555 for a discussion.
4538
Eric Smitha73fbe72008-02-23 03:09:44 +00004539- Added the future_builtins module, which contains hex() and oct().
4540 These are the PEP 3127 version of these functions, designed to be
4541 compatible with the hex() and oct() builtins from Python 3.0. They
4542 differ slightly in their output formats from the existing, unchanged
4543 Python 2.6 builtins. The expected usage of the future_builtins
4544 module is:
4545 from future_builtins import hex, oct
4546
Eric Smith7ef40bf2008-02-20 23:34:22 +00004547- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4548 exponents for exponents with absolute value < 100. Follows C99
4549 standard. This is a change on Windows, which would use 3 digits.
4550 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4551 so that any alterations it does to the resulting string will be
4552 available in stringlib/formatter.h (for float.__format__).
4553
Eric Smith5a3c1352008-02-19 13:21:56 +00004554- Implemented PEP 3101, Advanced String Formatting. This adds a new
4555 builtin format(); a format() method for str and unicode; a
4556 __format__() method to object, str, unicode, int, long, float, and
4557 datetime; the class string.Formatter; and the C API
4558 PyObject_Format().
4559
Georg Brandl3ee81df2008-05-17 18:14:43 +00004560- Fixed several potential crashes, all caused by specially crafted
4561 __del__ methods exploiting objects in temporarily inconsistent
4562 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004563
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004564- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004565 prevent a possible crash: an Abstract Base Class would try to access
4566 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004567
Georg Brandl3ee81df2008-05-17 18:14:43 +00004568- Fixed repr() and str() of complex numbers with infinity or nan as
4569 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004570
Georg Brandl3ee81df2008-05-17 18:14:43 +00004571- Clear all free lists during a gc.collect() of the highest generation
4572 in order to allow pymalloc to free more arenas. Python may give back
4573 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004574
Georg Brandl3ee81df2008-05-17 18:14:43 +00004575- Issue #2045: Fix an infinite recursion triggered when printing a
4576 subclass of collections.defaultdict, if its default_factory is set
4577 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004578
Christian Heimesf75dbef2008-02-08 00:11:31 +00004579- Fixed a minor memory leak in dictobject.c. The content of the free
4580 list was not freed on interpreter shutdown.
4581
Georg Brandl21e99f42010-03-07 15:23:59 +00004582- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004583 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004584
Georg Brandl3ee81df2008-05-17 18:14:43 +00004585- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4586 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004587 to compact the internal free lists of pre-allocted ints and floats.
4588
Georg Brandl3ee81df2008-05-17 18:14:43 +00004589- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4590 calls. Python expected the return type int but the fork familie
4591 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004592
Georg Brandl3ee81df2008-05-17 18:14:43 +00004593- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4594 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004595
Georg Brandl3ee81df2008-05-17 18:14:43 +00004596- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4597 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004598
Georg Brandl3ee81df2008-05-17 18:14:43 +00004599- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4600 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004601
Georg Brandl3ee81df2008-05-17 18:14:43 +00004602- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4603 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004604
Georg Brandl3ee81df2008-05-17 18:14:43 +00004605- Patch #1473257: generator objects gain a gi_code attribute. This is
4606 the same object as the func_code attribute of the function that
4607 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004608
Georg Brandl3ee81df2008-05-17 18:14:43 +00004609- Issue #1920: "while 0" statements were completely removed by the
4610 compiler, even in the presence of an "else" clause, which is
4611 supposed to be run when the condition is false. Now the compiler
4612 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004613
Guido van Rossumeead05f2008-01-24 18:21:02 +00004614- A few crashers fixed: weakref_in_del.py (issue #1377858);
4615 loosing_dict_ref.py (issue #1303614, test67.py);
4616 borrowed_ref_[34].py (not in tracker).
4617
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004618- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004619 suppressed while an extension is loaded by calling SetErrorMode in
4620 dynload_win.c. The error is still reported properly.
4621
Georg Brandl3ee81df2008-05-17 18:14:43 +00004622- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004623 several extension methods and modules do not work without unicode
4624 support.
4625
Georg Brandl26543b12008-01-21 18:36:51 +00004626- Issue #1882: when compiling code from a string, encoding cookies in the
4627 second line of code were not always recognized correctly.
4628
Georg Brandl14404b62008-01-19 19:27:05 +00004629- Issue #1679: "0x" was taken as a valid integer literal.
4630
Georg Brandl6caad7d2008-01-26 14:19:22 +00004631- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004632 added.
4633
Christian Heimesc94e2b52008-01-14 04:13:37 +00004634- sys.float_info / PyFloat_GetInfo: The floating point information
4635 object was converted from a dict to a specialized structseq object.
4636
Georg Brandl3ee81df2008-05-17 18:14:43 +00004637- Patch #1816: Added sys.flags structseq. It exposes the status of
4638 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004639
Georg Brandl3ee81df2008-05-17 18:14:43 +00004640- Objects/structseq.c: Implemented new structseq representation. The
4641 patch makes structseqs (e.g. the return value of os.stat) more
4642 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004643
Georg Brandl3ee81df2008-05-17 18:14:43 +00004644- Patch #1700288: added a type attribute cache that caches method
4645 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004646
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004647- Bug #1776: __import__() no longer accepts filenames on any platform.
4648 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004649
Georg Brandlaed6c662008-01-07 17:25:53 +00004650- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4651
Georg Brandl3ee81df2008-05-17 18:14:43 +00004652- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4653 envvar and sys.dont_write_bytecode attribute. All these can be set
4654 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004655
Georg Brandl3ee81df2008-05-17 18:14:43 +00004656- Improve some exception messages when Windows fails to load an
4657 extension module. Now we get for example '%1 is not a valid Win32
4658 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004659
Georg Brandl3ee81df2008-05-17 18:14:43 +00004660- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004662- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4663 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004664
Christian Heimes0a8143f2007-12-18 23:22:54 +00004665- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004666 and INF. float("nan"), float("inf") and float("-inf") now work on
4667 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004668
Georg Brandl3ee81df2008-05-17 18:14:43 +00004669- Compiler now generates simpler and faster code for dictionary
4670 literals. The oparg for BUILD_MAP now indicates an estimated
4671 dictionary size. There is a new opcode, STORE_MAP, for adding
4672 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004673
Georg Brandl3ee81df2008-05-17 18:14:43 +00004674- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004679- Issue #1538: Avoid copying string in split/rsplit if the split char
4680 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004681
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004682- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004683 SystemError.
4684
Nick Coghlanef01d822007-12-03 12:55:17 +00004685- PEP 366: Allow explicit relative imports when executing modules
4686 inside packages with the -m switch via a new module level
4687 __package__ attribute.
4688
Georg Brandl3ee81df2008-05-17 18:14:43 +00004689- Issue #1402: Fix a crash on exit, when another thread is still
4690 running, and if the deallocation of its frames somehow calls the
4691 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004692

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00004696 attribute of an empty cell object.
4697
Georg Brandl3ee81df2008-05-17 18:14:43 +00004698- Issue #1460: The utf-7 incremental decoder did not accept truncated
4699 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00004700
Georg Brandl3ee81df2008-05-17 18:14:43 +00004701- Patch #1739468: Directories and zipfiles containing a __main__.py
4702 file can now be directly executed by passing their name to the
4703 interpreter. The directory/zipfile is automatically inserted as the
4704 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004705
Georg Brandl3ee81df2008-05-17 18:14:43 +00004706- Issue #1265: Fix a problem with sys.settrace, if the tracing
4707 function uses a generator expression when at the same time the
4708 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004709
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004710- sets and frozensets now have an isdisjoint() method.
4711
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004712- optimize the performance of builtin.sum().
4713
Neal Norwitz44f326e2007-10-05 05:29:17 +00004714- Fix warnings found by the new version of the Coverity checker.
4715
Georg Brandl21e99f42010-03-07 15:23:59 +00004716- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004717 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4718 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004719
Georg Brandl3ee81df2008-05-17 18:14:43 +00004720- Issue #1686386: Tuple's tp_repr did not take into account the
4721 possibility of having a self-referential tuple, which is possible
4722 from C code. Nor did object's tp_str consider that a type's tp_str
4723 could do something that could lead to an inifinite recursion.
4724 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4725 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004726
Georg Brandl3ee81df2008-05-17 18:14:43 +00004727- Issue #1164: It was possible to trigger deadlock when using the
4728 'print' statement to write to a file since the GIL was not released
4729 as needed. Now PyObject_Print() does the right thing along with
4730 various tp_print implementations of the built-in types and those in
4731 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004732
Georg Brandl3ee81df2008-05-17 18:14:43 +00004733- Issue #1147: Exceptions were directly allowing string exceptions in
4734 their throw() method even though string exceptions no longer
4735 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004736

Brett Cannon1e534b52007-09-07 04:18:30 +00004740- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004741 PyObject_Call() never calling back out to Python code to trigger
4742 recursion depth updates/checks. Required the creation of a static
4743 RuntimeError instance in case normalizing an exception put the
4744 recursion check value past its limit. Fixes crashers
4745 infinite_rec_(1|2|4|5).py.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004761 __*__ attributes. (Some already existed, e.g., __doc__ and
4762 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004763
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004764- Add -3 option to the interpreter to warn about features that are

Georg Brandl3ee81df2008-05-17 18:14:43 +00004771 "except E as target:". This is to provide forwards compatibility
4772 with Python 3.0.

Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004780 setting a plain string, ie don't expand to single letter identifiers.
4781
Raymond Hettinger13936692007-04-11 18:40:58 +00004782- Request #1191699: Slices can now be pickled.

4792
Guido van Rossum143b5642007-03-23 04:58:42 +00004793- Bug #1683368: The object.__init__() and object.__new__() methods are
4794 now stricter in rejecting excess arguments. The only time when
4795 either allows excess arguments is when it is not overridden and the
4796 other one is. For backwards compatibility, when both are
4797 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004798 warning later). Also, type.__init__() insists on the same signature
4799 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004800
Georg Brandl3ee81df2008-05-17 18:14:43 +00004801- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4802 object to complex using its __complex__() method before falling back
4803 to the __float__() method. Therefore, the functions in the cmath
4804 module now can operate on objects that define a __complex__()
4805 method.

4822
Georg Brandl7b9c5552007-03-12 14:30:05 +00004823- Bug #1678647: write a newline after printing an exception in any
4824 case, even when converting the value to a string failed.
4825
Georg Brandl871f1bc2007-03-12 13:17:36 +00004826- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004827 its argument, if it exists. If not, it will work like before. This
4828 allows customizing the output of dir() in the presence of a
4829 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004830
Collin Winter276887b2007-03-12 16:11:39 +00004831- Patch #922167: Python no longer segfaults when faced with infinitely
4832 self-recursive reload() calls (as reported by bug #742342).

4838 parthensized forms. This means complex(repr(x)) now works instead of
4839 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004840
Georg Brandlaa2321b2007-03-07 00:40:28 +00004841- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004842 makes the filenames the warning module prints much more sensible
4843 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004844

Georg Brandl0fca97a2007-03-05 22:28:08 +00004856- Patch #1674228: when assigning a slice (old-style), check for the
4857 sq_ass_slice instead of the sq_slice slot.
4858
Georg Brandl3ee81df2008-05-17 18:14:43 +00004859- When printing an unraisable error, don't print exceptions. before

5484
Georg Brandl3ee81df2008-05-17 18:14:43 +00005485- unittest now verifies more of its assumptions. In particular,

5487 accepted in TestSuite.addTest(). This should cause no
5488 incompatibility since it never made sense with ordinary subclasses
5489 -- the failure just occurred later, with a more cumbersome
5490 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005771- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5772 with RFC 3207 and forgets any knowledge obtained from the server not
5773 obtained from the TLS negotiation itself. Patch contributed by Bill
5774 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005775
Georg Brandl3ee81df2008-05-17 18:14:43 +00005776- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005777 that the SMTP.starttls() caller no longer needs to call ehlo()
5778 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005779 does not claim to support starttls. Adds the
5780 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5861 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5862 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00005879 time so that opening a database previously created with the DB_DUP
5880 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5881 opens. Specifically: dictionary assignment to a DB object will
5882 replace all values for a given key when the database allows
5883 duplicate values. DB users should use DB.put(k, v) when they want
5884 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005885

5891 characters with ASCII value less than 32. Also, it correctly quotes
5892 dots only if they occur on a single line, as opposed to the previous
5893 behavior of quoting dots if they are the second character of any
5894 line.

6217-----
6218
Georg Brandl3ee81df2008-05-17 18:14:43 +00006219- Unified naming convention for free lists and their limits. All free
6220 lists in Object/ are named ``free_list``, the counter ``numfree``
6221 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
6222 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00006223
Georg Brandl3ee81df2008-05-17 18:14:43 +00006224- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6225 to ``PyTuple_SetItem``, it can be used to populate a brand new
6226 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00006227
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006228- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00006229
Georg Brandl3ee81df2008-05-17 18:14:43 +00006230- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
6231 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
6232 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006233
6234- Patch #1720595: add T_BOOL to the range of structmember types.
6235
6236- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
6237 ``PyFloat_GetInfo()`` to the float API.
6238
Georg Brandl3ee81df2008-05-17 18:14:43 +00006239- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6240 of w# format code incorrectly truncated the length to an int, even
6241 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6242 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006243
Georg Brandl3ee81df2008-05-17 18:14:43 +00006244- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
6245 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006246
Georg Brandl3ee81df2008-05-17 18:14:43 +00006247- PEP 3123: Provide forward compatibility with Python 3.0, while
6248 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
6249 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006250
Georg Brandl3ee81df2008-05-17 18:14:43 +00006251- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
6252 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006253
6254- Patch #1733960: Allow T_LONGLONG to accept ints.
6255
6256- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
6257
Christian Heimes000a0742008-01-03 22:16:32 +00006258- Added a new API function ``PyImport_ImportModuleNoBlock``.
6259
Georg Brandl6caad7d2008-01-26 14:19:22 +00006260- Bug #1637022: Prefix AST symbols with _Py_.
6261
6262- Fix some leftovers from the conversion from int to Py_ssize_t
6263 (relevant to strings and sequences of more than 2**31 items).
6264
6265- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6266 outside of pystate.c and should not be necessary.
6267
Georg Brandl3ee81df2008-05-17 18:14:43 +00006268- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6269 absolute imports. In earlier versions they might have used relative
6270 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006271
Georg Brandl3ee81df2008-05-17 18:14:43 +00006272- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6273 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006274
Georg Brandl3ee81df2008-05-17 18:14:43 +00006275- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
6276 macro so it can be used as an expression.

6281
Georg Brandl3ee81df2008-05-17 18:14:43 +00006282- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
6283 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6284 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6285 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00006286
Georg Brandl3ee81df2008-05-17 18:14:43 +00006287- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
6288 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006300- Removed the macfs module. It had been deprecated since Python 2.5.
6301 This lead to the deprecation of macostools.touched() as it relied
6302 solely on macfs and was a no-op under OS X.
