Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000211- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
212 start byte and the continuation byte(s) are now considered invalid, instead
213 of the number of bytes specified by the start byte.
214 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
215 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
216 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
217 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000225- Issue #8748: Fix two issues with comparisons between complex and integer
226 objects. (1) The comparison could incorrectly return True in some cases
227 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
228 (2) The comparison raised an OverflowError for large integers, leading
229 to unpredictable exceptions when combining integers and complex objects

Mark Dickinson81336372010-05-30 12:12:25 +0000232- Issue #5211: Implicit coercion for the complex type is now completely

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000572 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
573 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
574 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

594Core and Builtins
595-----------------
596
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000597- Issue #7301: Add environment variable $PYTHONWARNINGS.
598
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000599- Issue #8329: Don't return the same lists from select.select when no fds are
600 changed.
601
Georg Brandlfee0f442010-05-22 21:26:21 +0000602- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000603 on 64-bit machines. The shift count for either left or right shift is
604 permitted to be up to sys.maxsize.
605
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000606- Ensure that tokenization of identifiers is not affected by locale.
607
Georg Brandlfee0f442010-05-22 21:26:21 +0000608- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +0000609
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000610- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
611
Georg Brandlfee0f442010-05-22 21:26:21 +0000612- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
613 with a non-empty format string. This is an effort to future-proof user
614 code. If a derived class does not currently implement __format__ but later
615 adds its own __format__, it would most likely break user code that had
616 supplied a format string. This will be changed to a DeprecationWaring in
617 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000618
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000619- Issue #8268: Old-style classes (not just instances) now support weak

643
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000644- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000645 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
646 `ssl.OPENSSL_VERSION_NUMBER`.

649
Georg Brandlfee0f442010-05-22 21:26:21 +0000650- Issue #8257: The Decimal construct now accepts a float instance directly,
651 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000652
653 >>> Decimal(1.1)
654 Decimal('1.100000000000000088817841970012523233890533447265625')
655
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000656- collections.Counter() now supports a subtract() method.
657
Georg Brandlfee0f442010-05-22 21:26:21 +0000658- The functools module now has a total_ordering() class decorator to simplify
659 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000660
Georg Brandlfee0f442010-05-22 21:26:21 +0000661- The functools module also adds cmp_to_key() as a tool to transition old-style
662 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +0000663
Georg Brandlfee0f442010-05-22 21:26:21 +0000664- Issue #8294: The Fraction constructor now accepts Decimal and float instances
665 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000666
Georg Brandlfee0f442010-05-22 21:26:21 +0000667- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
668 InvalidOperation instead of returning False. (Comparisons involving a quiet
669 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
670 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000671
Georg Brandlfee0f442010-05-22 21:26:21 +0000672- Issue #2531: Comparison operations between floats and Decimal instances now
673 return a result based on the numeric values of the operands; previously they
674 returned an arbitrary result based on the relative ordering of id(float) and
675 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000676
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000677- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000678 argument `-` which tells it to read files to compile from stdin. Each line is
679 read on demand and the named file is compiled immediately. (Original patch by
680 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000681
Georg Brandlfee0f442010-05-22 21:26:21 +0000682- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +0000685- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
686 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +0000687 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +0000688
Georg Brandlfee0f442010-05-22 21:26:21 +0000689- Comparisons using one of <, <=, >, >= between a complex instance and a
690 Fractions instance now raise TypeError instead of returning True/False. This
691 makes Fraction <=> complex comparisons consistent with int <=> complex, float
692 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +0000693
Michael Foorde6410c52010-03-29 20:04:23 +0000694- Addition of ``WeakSet`` to the ``weakref`` module.

702
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000703- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +0000704 didn't support chflags() (for example ZFS under FreeBSD). The error is now
705 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000706
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000707- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
708 deprecated.
709
Georg Brandlfee0f442010-05-22 21:26:21 +0000710- Issue #7860: platform.uname now reports the correct 'machine' type when Python

Antoine Pitroueee91cd2010-03-26 19:27:16 +0000723- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
724 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
725 reads and writes are always retried by OpenSSL itself.

Victor Stinner75227342010-03-12 14:30:26 +0000746
Vinay Sajipecfa08f2010-03-12 09:16:10 +0000747- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +0000748 for ``TimedRotatingFileHandler`` by using the modification time of an existing
749 log file to compute the next rollover time. If the log file does not exist,
750 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000751
Georg Brandlba83f822010-03-14 09:50:54 +0000752- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Georg Brandlba83f822010-03-14 09:50:54 +0000760- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
761 a base64 transfer-encoded payload *after* decoding it; it no longer does.
762 This is a behavior change, so email's minor version number is now bumped, to
763 version 4.0.2, for the 2.7 release.

795
Georg Brandlba83f822010-03-14 09:50:54 +0000796- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
797 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
798 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +0000799 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
800 inconsistent: __int__ was used for some integer codes but not for others, and
801 the set of integer codes for which it was used differed between native packing

1202-----------------
1203
Georg Brandlba83f822010-03-14 09:50:54 +00001204- The ``__complex__()`` method is now looked up on the class of instances to
1205 make it consistent with other special methods.

1209
Mark Dickinson1b34d252010-01-01 17:27:30 +00001210- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001211 DeprecationWarning when passed a float argument where an integer was expected.
1212 These functions and methods now raise TypeError instead. The majority of the
1213 effects of this change are in the extension modules, but some core functions
1214 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1215 and many unicode/str methods.

1229 of integers: the result of a/b is now correctly rounded for ints a and b (at
1230 least on IEEE 754 platforms), and in particular does not depend on the
1231 internal representation of a long.

1239
Georg Brandlba83f822010-03-14 09:50:54 +00001240 These executables now work properly with the arch(1) command: ``arch -ppc
1241 python`` will start a universal binary version of python in PPC mode (unlike

1382 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001383
Georg Brandlba83f822010-03-14 09:50:54 +00001384- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1385 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001386
Georg Brandlba83f822010-03-14 09:50:54 +00001387- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1388 1e-100 used to raise OverflowError, but now gives the requested 120
1389 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001397
Georg Brandlba83f822010-03-14 09:50:54 +00001398- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1399 decimal string that's guaranteed to round back to x under correct rounding
1400 (with round-half-to-even rounding mode). Previously it gave a string based on
1401 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1402 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1403 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001404
Georg Brandlba83f822010-03-14 09:50:54 +00001405- Issue #7117: On almost all platforms: float-to-string and string-to-float
1406 conversions within Python are now correctly rounded. Places these conversions
1407 occur include: str for floats and complex numbers; the float and complex
1408 constructors; old-style and new-style numeric formatting; serialization and
1409 deserialization of floats and complex numbers using marshal, pickle and json;
1410 parsing of float and imaginary literals in Python code; Decimal-to-float
1411 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001412
Georg Brandlba83f822010-03-14 09:50:54 +00001413 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1414 providing correctly-rounded strtod and dtoa C functions. This code is
1415 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1416 the C compiler. There may be a small number of platforms on which correct
1417 operation of this code cannot be guaranteed, so the code is not used: notably,
1418 this applies to platforms where the C double format is not IEEE 754 binary64,
1419 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1420 and Python's configure script is unable to determine how to change the FPU
1421 precision. On these platforms conversions use the platform strtod and dtoa,
1422 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001424- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1425 uses the correctly-rounded string <-> float conversions described above (when
1426 available), and so produces correctly rounded results that will display nicely
1427 under the float repr. There are two related small changes: (1) round now
1428 accepts any class with an ``__index__()`` method for its second argument (but
1429 no longer accepts floats for the second argument), and (2) an excessively
1430 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1431 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00001573
Georg Brandlba83f822010-03-14 09:50:54 +00001574 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1575 (2) parsing of strings representing infinities and nans was locale aware; and
1576 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001578- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1579 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1580 but with at least one decimal point and with a default precision
1581 of 12. Previously, the behavior the same but with a default precision of 6.
1582 This more closely matches ``str()``, and reduces surprises when adding
1583 alignment flags to the empty presentation type. This also affects the new
1584 complex.__format__ in the same way.
1585
1586- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
1587 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00001649 untrackable objects are not tracked by the garbage collector. This can reduce
1650 the size of collections and therefore the garbage collection overhead on

1658 internal representation of integers, for performance reasons. Base 2**30 is
1659 enabled by default on 64-bit machines. Add --enable-big-digits option to
1660 configure, which overrides the default. Add sys.long_info structseq to

Georg Brandlba83f822010-03-14 09:50:54 +00001782- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1783 file objects with closefd=False. The file descriptor is still kept open but
1784 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00001808- On windows, ``os.chdir()`` given unicode was not working if
1809 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1810 this code path is really executed because I cannot move to such directory on
1811 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001813- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1814 element is temporarily replaced with an equivalent frozenset. But the
1815 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00001836- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1837 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1838 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1839 of using the replace error handler in PyUnicode_DecodeUTF8().
1840
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001841- Issue #3739: The unicode-internal encoder now reports the number of characters

1843
Georg Brandlba83f822010-03-14 09:50:54 +00001844- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

1846 gives improved memory leak detection when running under Valgrind, while taking
1847 advantage of pymalloc at other times.

3014 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3015 neither __int__ nor __long__, TypeError used to be raised (with a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003212- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3213
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003214- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3215 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3216 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3217 ``printf`` function, whereas PyString_FromFormat has an independent
3218 implementation and uses "%zd" on all platforms for size_t values.
3219 This makes a difference on win64, where ``printf`` needs "%Id" to display
3220 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00003222- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3226 object; previously an int would be returned for small values. the __long__
3227 method is allowed to return either an int or a long, but the behaviour of
3228 float objects should not change to respect backward compatibility.
3229
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003230- Issue #3751: str.rpartition would perform a left-partition when called with
3231 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00003236 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003237 was correctly parsed but parsing of subsequent arguments failed.
3238
Vinay Sajip35e3b032008-09-01 14:33:59 +00003239- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003240 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3241 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3242 when given a tuple of classes as second argument, were looking up
3243 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3244 type object.
3245
Neal Norwitz18aa3882008-08-24 05:04:52 +00003246- Fix crashes on memory allocation failure found with failmalloc.

3315 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3316 for catch_warnings() also led to an improvement in the raising of a

3389-----------------
3390
Guido van Rossumf8402962008-08-20 15:01:50 +00003391- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3392 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3393 extensions do not automatically benefit from the class attribute
3394 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3395 to their tp_flags field if they care. This is a backwards
3396 compatibility feature; in 3.0, all types will use the cache by
3397 default.
3398
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003399- Keyword arguments can now follow starred arguments. (``f(a, *args,
3400 keyword=23)`` is now valid syntax.)
3401
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003402- ctypes function pointers that are COM methods have a boolean True

Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003405- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3406 by denying s# to parse objects that have a releasebuffer procedure,
3407 and introducing s*.

Georg Brandl1e13ea92008-08-11 09:07:59 +00003409- Issue #3537: Fix an assertion failure when an empty but presized dict
3410 object was stored in the freelist.
3411
Mark Dickinsonb6467572008-08-04 21:30:09 +00003412- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3413 ValueError consistently across platforms.
3414
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003415- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3416 (64bit Unix, for example), unichr() would truncate its argument and return
3417 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3418
Neal Norwitze7d8be82008-07-31 17:17:14 +00003419- Apply security patches from Apple.
3420
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003421- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3422 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3423
Antoine Pitrou92f82162008-07-25 22:22:08 +00003424- Issue #1819: function calls with several named parameters are now on
3425 average 35% faster (as measured by pybench).
3426
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003427- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3428 the python debugger steps into a class statement: the free variables (local
3429 variables defined in an outer scope) would be deleted from the outer scope.
3430
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003431- Issue #2620: Overflow checking when allocating or reallocating memory
3432 was not always being done properly in some python types and extension
3433 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3434 all been updated to perform better checks and places in the code that
3435 would previously leak memory on the error path when such an allocation
3436 failed have been fixed.

3442
Benjamin Petersone977ad42008-08-20 01:42:01 +00003443- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3444 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3445
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003446- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3447 version reported by these tools does not necessarily follow the python
3448 version numbering scheme, so the module is less strict when parsing it.
3449
Nick Coghlanf70385a2008-08-18 12:42:46 +00003450- Issue #2235: Added Py3k warnings for types which will become unhashable
3451 under the stricter __hash__ inheritance rules in 3.0. Several types
3452 which did not meet the rules for hash invariants and were already
3453 unhashable in 3.0 have now been explicitly flagged as unhashable in
3454 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3455 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3456
Brett Cannon88f801d2008-08-18 00:46:22 +00003457- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3458 imported into the module but exposed as part of the module's API.

3480
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003481- Issue #2676: in the email package, content-type parsing was hanging on

3483 regular expression.
3484
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003485- Issue #3476: binary buffered reading through the new "io" library is now
3486 thread-safe.
3487
Brett Cannonbf3157b2008-08-14 05:00:03 +00003488- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3489 since mimetools itself is deprecated. Because modules are cached, all
3490 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3491
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003492- Issue #3134: shutil referenced undefined WindowsError symbol.

3498 version that did not raise a DeprecationWarning under -3.
3499
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003500- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3501 a MemoryError rather than silently stop the iteration.
3502
Guido van Rossum59ce9012008-08-09 14:55:34 +00003503- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3504 to _sre.compile() will now be rejected. This should not affect anybody
3505 since the re.compile() function never generates invalid re-bytecode.
3506
Skip Montanaroa032bf42008-08-08 22:52:51 +00003507- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3508 upon first access it can be automatically initialized from the csv file if
3509 it wasn't initialized during instantiation.
3510
Brett Cannon3aa2a492008-08-06 22:28:09 +00003511- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3512 the reload() built-in has been removed.
3513
Brett Cannon7e30b672008-08-04 21:52:25 +00003514- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003515 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3523 raised an AttributeError.
3524
Benjamin Peterson01a24322008-07-28 23:35:27 +00003525- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003526 asking for a specific length. This problem only affected files opened
3527 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003528

3551
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003552- Issue #3394: zipfile.writestr sets external attributes when passed a
3553 file name rather than a ZipInfo instance, so files are extracted with
3554 mode 0600 rather than 000 under Unix.
3555
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003556- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3557 argument in python 2.5, this broke code that subclassed Popen to include its
3558 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00003568- Issue #2235: the C API function PyObject_HashNotImplemented and its
3569 interaction with the tp_hash slot (added in 2.6b2) are now documented
3570
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003571- Issue #643841: The language reference now provides more detailed
3572 coverage of the lookup process for special methods. The disclaimers
3573 regarding lack of coverage of new-style classes have also been
3574 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003582Core and Builtins
3583-----------------
3584
Georg Brandl3e483f62008-07-16 22:57:41 +00003585- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3586 its methods now allow for items objects that can be converted to
3587 an integer using operator.index().
3588
Mark Dickinson64b7e502008-07-16 09:40:03 +00003589- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3590 produced a ValueError instead of giving the correct float.
3591
Eric Smitha5fa5a22008-07-16 00:11:49 +00003592- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3593 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3594
Mark Dickinson7103aa42008-07-15 19:08:33 +00003595- Issue #3008: the float type has a new instance method 'float.hex'
3596 and a new class method 'float.fromhex' to convert floating-point
3597 numbers to and from hexadecimal strings, respectively.
3598
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003599- Issue #2235: __hash__ is once again inherited by default. To allow
3600 collections.Hashable to remain meaningful in the presence of the
3601 default hash implementation (object.__hash__), it is now possible
3602 to explicit block inheritance of hash by setting __hash__=None at
3603 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3604 level.
3605
Nick Coghlanb028f502008-07-13 14:52:36 +00003606- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3607 the parent module cannot be found while performing an absolute import.
3608 This means that an incorrectly defined __package__ attribute will
3609 now only prevent relative imports in that module rather than causing
3610 all imports from that module to fail.
3611
Nick Coghlan14ff9942008-07-08 14:21:42 +00003612- Issue #2517: Allow unicode messages in Exceptions again by correctly
3613 bypassing the instance dictionary when looking up __unicode__ on
3614 new-style classes.
3615
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003616- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3617 set to a custom object whose write() method happens to install
3618 another file in sys.stdout.
3619
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003620- Issue #3088: Corrected a race condition in classes derived from
3621 threading.local: the first member set by a thread could be saved in
3622 another thread's dictionary.
3623
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003624- Issue #3004: Minor change to slice.indices(): the start and stop
3625 arguments are now treated identically, making the behaviour easier
3626 to describe and understand. For example, slice(None, -10,
3627 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3628 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3629 10, -1).
3630
Georg Brandl278fc502008-07-19 12:46:12 +00003631- Issue #3219: Calling a function with repeated keyword arguments,
3632 f(a=2, a=23), would not cause a syntax error. This was a regression
3633 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003634
Georg Brandl278fc502008-07-19 12:46:12 +00003635- Issue #2862: Make int and float freelist management consistent with
3636 other freelists. Changes their CompactFreeList apis into
3637 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00003638

3640-------
3641
Thomas Heller57adf222008-08-14 19:10:48 +00003642- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3643 api functions without holding the GIL, which could lead to a fatal
3644 error when they failed.
3645
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003646- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

3655 ForkingPickler.register() to resolve conflict with ctypes.
3656
Vinay Sajip51e65192008-07-18 09:01:10 +00003657- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00003659- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3660 a valid dlerror() message.
3661
Thomas Heller2bad6572008-07-15 17:19:50 +00003662- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3663 incomplete structure was created.
3664
Brett Cannon3d0b9f02008-07-13 01:15:07 +00003665- Issue #3339: dummy_thread.acquire() should not return None.
3666
Raymond Hettingerb01713e2008-07-10 14:34:57 +00003667- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
3668
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003669- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003670
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003671- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3672 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003673 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003674 content-length. The problem had been corrected in the 2.4 branch, but never
3675 merged into trunk.
3676
Georg Brandle78fbcc2008-07-05 10:13:36 +00003677- Issue #2663: add filtering capability to shutil.copytree().

3682
3683- Issue #1746: Correct handling of zipfile archive comments (previously
3684 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00003685 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00003686
Vinay Sajip51e65192008-07-18 09:01:10 +00003687- Issue #449227: The rlcompleter module now adds "(" to callable objects

4082 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004083 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004084
4085 This is controlled by the configure argument ``--with-universal-archs``:
4086
4087 - ``--with-universal-archs=all``: install 4-way universal
4088
4089 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4090
4091 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4092
4093 This option should be used in combination with ``--enable-universalsdk=``.
4094
4095 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 +00004145- Issue #1631171: Re-implement the 'warnings' module in C (the
4146 original Python code has been kept as backup). This will allow for
4147 using the 'warning's machinery in such places as the parser where
4148 use of pure Python code is not possible. Both the ``showarning()``
4149 and ``formatwarning()`` gain an optional 'line' argument which is
4150 not called by default for backwards-compatibility reasons. Setting
4151 ``warnings.showwarning()`` to an implementation that lacks support
4152 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004215- Issue #2550: The approach used by client/server code for obtaining
4216 ports to listen on in network-oriented tests has been refined in an
4217 effort to facilitate running multiple instances of the entire
4218 regression test suite in parallel without issue.
4219 test_support.bind_port() has been fixed such that it will always
4220 return a unique port -- which wasn't always the case with the
4221 previous implementation, especially if socket options had been set
4222 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4223 new implementation of bind_port() will actually raise an exception
4224 if it is passed an AF_INET/SOCK_STREAM socket with either the
4225 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4226 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4227 the socket it's been passed. This currently only applies to
4228 Windows. This option prevents any other sockets from binding to the
4229 host/port we've bound to, thus removing the possibility of the
4230 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4231 when a second SOCK_STREAM socket binds and accepts to a host/port
4232 that's already been bound by another socket. The optional preferred
4233 port parameter to bind_port() has been removed. Under no
4234 circumstances should tests be hard coding ports!
4235
4236 test_support.find_unused_port() has also been introduced, which will
4237 pass a temporary socket object to bind_port() in order to obtain an
4238 unused port. The temporary socket object is then closed and
4239 deleted, and the port is returned. This method should only be used
4240 for obtaining an unused port in order to pass to an external program
4241 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4242 a parameter to a server-oriented class that doesn't give you direct
4243 access to the underlying socket used.
4244
4245 Finally, test_support.HOST has been introduced, which should be used
4246 for the host argument of any relevant socket calls (i.e. bind and
4247 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004248

4521Core and builtins
4522-----------------
4523
Fred Drakea8ee94b2008-03-01 02:45:07 +00004524- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004525 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004526
Georg Brandlad61bc82008-02-23 15:11:18 +00004527- Issue #2067: file.__exit__() now calls subclasses' close() method.
4528
4529- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004530
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004531- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004532 issue 215555 for a discussion.
4533
Eric Smitha73fbe72008-02-23 03:09:44 +00004534- Added the future_builtins module, which contains hex() and oct().
4535 These are the PEP 3127 version of these functions, designed to be
4536 compatible with the hex() and oct() builtins from Python 3.0. They
4537 differ slightly in their output formats from the existing, unchanged
4538 Python 2.6 builtins. The expected usage of the future_builtins
4539 module is:
4540 from future_builtins import hex, oct
4541
Eric Smith7ef40bf2008-02-20 23:34:22 +00004542- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4543 exponents for exponents with absolute value < 100. Follows C99
4544 standard. This is a change on Windows, which would use 3 digits.
4545 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4546 so that any alterations it does to the resulting string will be
4547 available in stringlib/formatter.h (for float.__format__).
4548
Eric Smith5a3c1352008-02-19 13:21:56 +00004549- Implemented PEP 3101, Advanced String Formatting. This adds a new
4550 builtin format(); a format() method for str and unicode; a
4551 __format__() method to object, str, unicode, int, long, float, and
4552 datetime; the class string.Formatter; and the C API
4553 PyObject_Format().
4554
Georg Brandl3ee81df2008-05-17 18:14:43 +00004555- Fixed several potential crashes, all caused by specially crafted
4556 __del__ methods exploiting objects in temporarily inconsistent
4557 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004558
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004559- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004560 prevent a possible crash: an Abstract Base Class would try to access
4561 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004562
Georg Brandl3ee81df2008-05-17 18:14:43 +00004563- Fixed repr() and str() of complex numbers with infinity or nan as
4564 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004565
Georg Brandl3ee81df2008-05-17 18:14:43 +00004566- Clear all free lists during a gc.collect() of the highest generation
4567 in order to allow pymalloc to free more arenas. Python may give back
4568 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004569
Georg Brandl3ee81df2008-05-17 18:14:43 +00004570- Issue #2045: Fix an infinite recursion triggered when printing a
4571 subclass of collections.defaultdict, if its default_factory is set
4572 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004573
Christian Heimesf75dbef2008-02-08 00:11:31 +00004574- Fixed a minor memory leak in dictobject.c. The content of the free
4575 list was not freed on interpreter shutdown.
4576
Georg Brandl21e99f42010-03-07 15:23:59 +00004577- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004578 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004579
Georg Brandl3ee81df2008-05-17 18:14:43 +00004580- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4581 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004582 to compact the internal free lists of pre-allocted ints and floats.
4583
Georg Brandl3ee81df2008-05-17 18:14:43 +00004584- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4585 calls. Python expected the return type int but the fork familie
4586 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004587
Georg Brandl3ee81df2008-05-17 18:14:43 +00004588- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4589 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004590
Georg Brandl3ee81df2008-05-17 18:14:43 +00004591- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4592 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004593
Georg Brandl3ee81df2008-05-17 18:14:43 +00004594- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4595 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004596
Georg Brandl3ee81df2008-05-17 18:14:43 +00004597- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4598 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004599
Georg Brandl3ee81df2008-05-17 18:14:43 +00004600- Patch #1473257: generator objects gain a gi_code attribute. This is
4601 the same object as the func_code attribute of the function that
4602 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004603
Georg Brandl3ee81df2008-05-17 18:14:43 +00004604- Issue #1920: "while 0" statements were completely removed by the
4605 compiler, even in the presence of an "else" clause, which is
4606 supposed to be run when the condition is false. Now the compiler
4607 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004608
Guido van Rossumeead05f2008-01-24 18:21:02 +00004609- A few crashers fixed: weakref_in_del.py (issue #1377858);
4610 loosing_dict_ref.py (issue #1303614, test67.py);
4611 borrowed_ref_[34].py (not in tracker).
4612
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004613- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004614 suppressed while an extension is loaded by calling SetErrorMode in
4615 dynload_win.c. The error is still reported properly.
4616
Georg Brandl3ee81df2008-05-17 18:14:43 +00004617- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004618 several extension methods and modules do not work without unicode
4619 support.
4620
Georg Brandl26543b12008-01-21 18:36:51 +00004621- Issue #1882: when compiling code from a string, encoding cookies in the
4622 second line of code were not always recognized correctly.
4623
Georg Brandl14404b62008-01-19 19:27:05 +00004624- Issue #1679: "0x" was taken as a valid integer literal.
4625
Georg Brandl6caad7d2008-01-26 14:19:22 +00004626- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004627 added.
4628
Christian Heimesc94e2b52008-01-14 04:13:37 +00004629- sys.float_info / PyFloat_GetInfo: The floating point information
4630 object was converted from a dict to a specialized structseq object.
4631
Georg Brandl3ee81df2008-05-17 18:14:43 +00004632- Patch #1816: Added sys.flags structseq. It exposes the status of
4633 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004634
Georg Brandl3ee81df2008-05-17 18:14:43 +00004635- Objects/structseq.c: Implemented new structseq representation. The
4636 patch makes structseqs (e.g. the return value of os.stat) more
4637 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004638
Georg Brandl3ee81df2008-05-17 18:14:43 +00004639- Patch #1700288: added a type attribute cache that caches method
4640 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004641
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004642- Bug #1776: __import__() no longer accepts filenames on any platform.
4643 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004644
Georg Brandlaed6c662008-01-07 17:25:53 +00004645- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4646
Georg Brandl3ee81df2008-05-17 18:14:43 +00004647- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4648 envvar and sys.dont_write_bytecode attribute. All these can be set
4649 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004650
Georg Brandl3ee81df2008-05-17 18:14:43 +00004651- Improve some exception messages when Windows fails to load an
4652 extension module. Now we get for example '%1 is not a valid Win32
4653 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004654
Georg Brandl3ee81df2008-05-17 18:14:43 +00004655- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004657- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4658 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004659
Christian Heimes0a8143f2007-12-18 23:22:54 +00004660- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004661 and INF. float("nan"), float("inf") and float("-inf") now work on
4662 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004663
Georg Brandl3ee81df2008-05-17 18:14:43 +00004664- Compiler now generates simpler and faster code for dictionary
4665 literals. The oparg for BUILD_MAP now indicates an estimated
4666 dictionary size. There is a new opcode, STORE_MAP, for adding
4667 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004668
Georg Brandl3ee81df2008-05-17 18:14:43 +00004669- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004674- Issue #1538: Avoid copying string in split/rsplit if the split char
4675 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004676
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004677- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004678 SystemError.
4679
Nick Coghlanef01d822007-12-03 12:55:17 +00004680- PEP 366: Allow explicit relative imports when executing modules
4681 inside packages with the -m switch via a new module level
4682 __package__ attribute.
4683
Georg Brandl3ee81df2008-05-17 18:14:43 +00004684- Issue #1402: Fix a crash on exit, when another thread is still
4685 running, and if the deallocation of its frames somehow calls the
4686 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004687

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00004691 attribute of an empty cell object.
4692
Georg Brandl3ee81df2008-05-17 18:14:43 +00004693- Issue #1460: The utf-7 incremental decoder did not accept truncated
4694 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00004695
Georg Brandl3ee81df2008-05-17 18:14:43 +00004696- Patch #1739468: Directories and zipfiles containing a __main__.py
4697 file can now be directly executed by passing their name to the
4698 interpreter. The directory/zipfile is automatically inserted as the
4699 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004700
Georg Brandl3ee81df2008-05-17 18:14:43 +00004701- Issue #1265: Fix a problem with sys.settrace, if the tracing
4702 function uses a generator expression when at the same time the
4703 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004704
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004705- sets and frozensets now have an isdisjoint() method.
4706
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004707- optimize the performance of builtin.sum().
4708
Neal Norwitz44f326e2007-10-05 05:29:17 +00004709- Fix warnings found by the new version of the Coverity checker.
4710
Georg Brandl21e99f42010-03-07 15:23:59 +00004711- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004712 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4713 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004714
Georg Brandl3ee81df2008-05-17 18:14:43 +00004715- Issue #1686386: Tuple's tp_repr did not take into account the
4716 possibility of having a self-referential tuple, which is possible
4717 from C code. Nor did object's tp_str consider that a type's tp_str
4718 could do something that could lead to an inifinite recursion.
4719 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4720 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004721
Georg Brandl3ee81df2008-05-17 18:14:43 +00004722- Issue #1164: It was possible to trigger deadlock when using the
4723 'print' statement to write to a file since the GIL was not released
4724 as needed. Now PyObject_Print() does the right thing along with
4725 various tp_print implementations of the built-in types and those in
4726 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004727
Georg Brandl3ee81df2008-05-17 18:14:43 +00004728- Issue #1147: Exceptions were directly allowing string exceptions in
4729 their throw() method even though string exceptions no longer
4730 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004731

Brett Cannon1e534b52007-09-07 04:18:30 +00004735- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004736 PyObject_Call() never calling back out to Python code to trigger
4737 recursion depth updates/checks. Required the creation of a static
4738 RuntimeError instance in case normalizing an exception put the
4739 recursion check value past its limit. Fixes crashers
4740 infinite_rec_(1|2|4|5).py.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004756 __*__ attributes. (Some already existed, e.g., __doc__ and
4757 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004758
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004759- Add -3 option to the interpreter to warn about features that are

Georg Brandl3ee81df2008-05-17 18:14:43 +00004766 "except E as target:". This is to provide forwards compatibility
4767 with Python 3.0.

Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004775 setting a plain string, ie don't expand to single letter identifiers.
4776
Raymond Hettinger13936692007-04-11 18:40:58 +00004777- Request #1191699: Slices can now be pickled.

4787
Guido van Rossum143b5642007-03-23 04:58:42 +00004788- Bug #1683368: The object.__init__() and object.__new__() methods are
4789 now stricter in rejecting excess arguments. The only time when
4790 either allows excess arguments is when it is not overridden and the
4791 other one is. For backwards compatibility, when both are
4792 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004793 warning later). Also, type.__init__() insists on the same signature
4794 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004795
Georg Brandl3ee81df2008-05-17 18:14:43 +00004796- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4797 object to complex using its __complex__() method before falling back
4798 to the __float__() method. Therefore, the functions in the cmath
4799 module now can operate on objects that define a __complex__()
4800 method.

4817
Georg Brandl7b9c5552007-03-12 14:30:05 +00004818- Bug #1678647: write a newline after printing an exception in any
4819 case, even when converting the value to a string failed.
4820
Georg Brandl871f1bc2007-03-12 13:17:36 +00004821- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004822 its argument, if it exists. If not, it will work like before. This
4823 allows customizing the output of dir() in the presence of a
4824 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004825
Collin Winter276887b2007-03-12 16:11:39 +00004826- Patch #922167: Python no longer segfaults when faced with infinitely
4827 self-recursive reload() calls (as reported by bug #742342).

4833 parthensized forms. This means complex(repr(x)) now works instead of
4834 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004835
Georg Brandlaa2321b2007-03-07 00:40:28 +00004836- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004837 makes the filenames the warning module prints much more sensible
4838 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004839

Georg Brandl0fca97a2007-03-05 22:28:08 +00004851- Patch #1674228: when assigning a slice (old-style), check for the
4852 sq_ass_slice instead of the sq_slice slot.
4853
Georg Brandl3ee81df2008-05-17 18:14:43 +00004854- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00005480- unittest now verifies more of its assumptions. In particular,

5482 accepted in TestSuite.addTest(). This should cause no
5483 incompatibility since it never made sense with ordinary subclasses
5484 -- the failure just occurred later, with a more cumbersome
5485 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005766- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5767 with RFC 3207 and forgets any knowledge obtained from the server not
5768 obtained from the TLS negotiation itself. Patch contributed by Bill
5769 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005770
Georg Brandl3ee81df2008-05-17 18:14:43 +00005771- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005772 that the SMTP.starttls() caller no longer needs to call ehlo()
5773 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005774 does not claim to support starttls. Adds the
5775 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00005830- itertools.chain() now has an alternate constructor,

5856 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5857 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00005874 time so that opening a database previously created with the DB_DUP
5875 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5876 opens. Specifically: dictionary assignment to a DB object will
5877 replace all values for a given key when the database allows
5878 duplicate values. DB users should use DB.put(k, v) when they want
5879 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005880

5886 characters with ASCII value less than 32. Also, it correctly quotes
5887 dots only if they occur on a single line, as opposed to the previous
5888 behavior of quoting dots if they are the second character of any
5889 line.

6213
Georg Brandl3ee81df2008-05-17 18:14:43 +00006214- Unified naming convention for free lists and their limits. All free
6215 lists in Object/ are named ``free_list``, the counter ``numfree``
6216 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
6217 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00006218
Georg Brandl3ee81df2008-05-17 18:14:43 +00006219- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6220 to ``PyTuple_SetItem``, it can be used to populate a brand new
6221 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00006222
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006223- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00006224
Georg Brandl3ee81df2008-05-17 18:14:43 +00006225- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
6226 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
6227 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006228
6229- Patch #1720595: add T_BOOL to the range of structmember types.
6230
6231- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
6232 ``PyFloat_GetInfo()`` to the float API.
6233
Georg Brandl3ee81df2008-05-17 18:14:43 +00006234- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6235 of w# format code incorrectly truncated the length to an int, even
6236 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6237 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006238
Georg Brandl3ee81df2008-05-17 18:14:43 +00006239- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
6240 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006241
Georg Brandl3ee81df2008-05-17 18:14:43 +00006242- PEP 3123: Provide forward compatibility with Python 3.0, while
6243 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
6244 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006245
Georg Brandl3ee81df2008-05-17 18:14:43 +00006246- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
6247 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006248
6249- Patch #1733960: Allow T_LONGLONG to accept ints.
6250
6251- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
6252
Christian Heimes000a0742008-01-03 22:16:32 +00006253- Added a new API function ``PyImport_ImportModuleNoBlock``.
6254
Georg Brandl6caad7d2008-01-26 14:19:22 +00006255- Bug #1637022: Prefix AST symbols with _Py_.
6256
6257- Fix some leftovers from the conversion from int to Py_ssize_t
6258 (relevant to strings and sequences of more than 2**31 items).
6259
6260- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6261 outside of pystate.c and should not be necessary.
6262
Georg Brandl3ee81df2008-05-17 18:14:43 +00006263- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6264 absolute imports. In earlier versions they might have used relative
6265 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006266
Georg Brandl3ee81df2008-05-17 18:14:43 +00006267- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6268 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006269
Georg Brandl3ee81df2008-05-17 18:14:43 +00006270- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
6271 macro so it can be used as an expression.

6276
Georg Brandl3ee81df2008-05-17 18:14:43 +00006277- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
6278 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6279 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6280 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00006281
Georg Brandl3ee81df2008-05-17 18:14:43 +00006282- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
6283 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006295- Removed the macfs module. It had been deprecated since Python 2.5.
6296 This lead to the deprecation of macostools.touched() as it relied
6297 solely on macfs and was a no-op under OS X.
