Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000191- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
192 start byte and the continuation byte(s) are now considered invalid, instead
193 of the number of bytes specified by the start byte.
194 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
195 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
196 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
197 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000205- Issue #8748: Fix two issues with comparisons between complex and integer
206 objects. (1) The comparison could incorrectly return True in some cases
207 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
208 (2) The comparison raised an OverflowError for large integers, leading

210 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +0000212- Issue #5211: Implicit coercion for the complex type is now completely

350 non-float non-integer argument is now converted to an integer (if possible)

405 trapped, the specification determines the order in which the signals should be
406 handled. In many cases this order wasn't being followed, leading to the wrong

Georg Brandlfee0f442010-05-22 21:26:21 +0000551- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000552 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
553 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
554 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

Benjamin Petersonfbac6c12010-04-10 16:22:05 +0000572*Release date: 2010-04-10*
Benjamin Peterson5da7e7c2010-03-06 22:44:07 +0000573
574Core and Builtins
575-----------------
576
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000577- Issue #7301: Add environment variable $PYTHONWARNINGS.
578
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000579- Issue #8329: Don't return the same lists from select.select when no fds are
580 changed.
581
Georg Brandlfee0f442010-05-22 21:26:21 +0000582- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000583 on 64-bit machines. The shift count for either left or right shift is
584 permitted to be up to sys.maxsize.
585
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000586- Ensure that tokenization of identifiers is not affected by locale.
587
Georg Brandlfee0f442010-05-22 21:26:21 +0000588- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +0000589
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000590- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
591
Georg Brandlfee0f442010-05-22 21:26:21 +0000592- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
593 with a non-empty format string. This is an effort to future-proof user
594 code. If a derived class does not currently implement __format__ but later
595 adds its own __format__, it would most likely break user code that had
596 supplied a format string. This will be changed to a DeprecationWaring in
597 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000598
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000599- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinnerc7790ed2010-03-22 12:36:28 +0000605- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +0000606
Benjamin Peterson96545892010-03-21 20:21:00 +0000607- Issue #6474: Make error message from passing an inadequate number of keyword
608 arguments to a function correct.
609
Benjamin Peterson0dee9c12010-03-17 20:41:42 +0000610- Issue #8164: Don't allow lambda functions to have a docstring.

Victor Stinner66644262010-03-10 22:30:19 +0000612- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +0000613 (SIGINT). If an error occurs while importing the site module, the error is
614 printed and Python exits. Initialize the GIL before importing the site

623
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000624- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000625 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
626 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000627
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000628- Issue #8310: Allow dis to examine new style classes.
629
Georg Brandlfee0f442010-05-22 21:26:21 +0000630- Issue #8257: The Decimal construct now accepts a float instance directly,
631 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000632
633 >>> Decimal(1.1)
634 Decimal('1.100000000000000088817841970012523233890533447265625')
635
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000636- collections.Counter() now supports a subtract() method.
637
Georg Brandlfee0f442010-05-22 21:26:21 +0000638- The functools module now has a total_ordering() class decorator to simplify
639 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000640
Georg Brandlfee0f442010-05-22 21:26:21 +0000641- The functools module also adds cmp_to_key() as a tool to transition old-style
642 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +0000643
Georg Brandlfee0f442010-05-22 21:26:21 +0000644- Issue #8294: The Fraction constructor now accepts Decimal and float instances
645 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000646
Georg Brandlfee0f442010-05-22 21:26:21 +0000647- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
648 InvalidOperation instead of returning False. (Comparisons involving a quiet
649 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
650 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000651
Georg Brandlfee0f442010-05-22 21:26:21 +0000652- Issue #2531: Comparison operations between floats and Decimal instances now
653 return a result based on the numeric values of the operands; previously they
654 returned an arbitrary result based on the relative ordering of id(float) and
655 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000656
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000657- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000658 argument `-` which tells it to read files to compile from stdin. Each line is
659 read on demand and the named file is compiled immediately. (Original patch by
660 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000661
Georg Brandlfee0f442010-05-22 21:26:21 +0000662- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +0000665- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
666 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +0000667 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +0000668
Georg Brandlfee0f442010-05-22 21:26:21 +0000669- Comparisons using one of <, <=, >, >= between a complex instance and a
670 Fractions instance now raise TypeError instead of returning True/False. This
671 makes Fraction <=> complex comparisons consistent with int <=> complex, float
672 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +0000673

682
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000683- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +0000684 didn't support chflags() (for example ZFS under FreeBSD). The error is now
685 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000686
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000687- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
688 deprecated.
689
Georg Brandlfee0f442010-05-22 21:26:21 +0000690- Issue #7860: platform.uname now reports the correct 'machine' type when Python
691 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +0000692

697 existing at the same time, causing a Unicode error when configuration code
698 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +0000699

Antoine Pitroueee91cd2010-03-26 19:27:16 +0000703- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
704 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
705 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +0000706

713 memoryviews.
Antoine Pitroud7b731d2010-03-17 22:45:39 +0000714
Matthias Klose8b411682010-03-16 10:48:52 +0000715- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
716 with Tcl/Tk-8.5.

Vinay Sajipecfa08f2010-03-12 09:16:10 +0000727- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +0000728 for ``TimedRotatingFileHandler`` by using the modification time of an existing
729 log file to compute the next rollover time. If the log file does not exist,
730 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000731
Georg Brandlba83f822010-03-14 09:50:54 +0000732- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Georg Brandlba83f822010-03-14 09:50:54 +0000740- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
741 a base64 transfer-encoded payload *after* decoding it; it no longer does.
742 This is a behavior change, so email's minor version number is now bumped, to
743 version 4.0.2, for the 2.7 release.

775
Georg Brandlba83f822010-03-14 09:50:54 +0000776- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
777 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
778 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +0000779 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
780 inconsistent: __int__ was used for some integer codes but not for others, and
781 the set of integer codes for which it was used differed between native packing
782 and standard packing.)

1182-----------------
1183
Georg Brandlba83f822010-03-14 09:50:54 +00001184- The ``__complex__()`` method is now looked up on the class of instances to
1185 make it consistent with other special methods.

1189
Mark Dickinson1b34d252010-01-01 17:27:30 +00001190- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001191 DeprecationWarning when passed a float argument where an integer was expected.
1192 These functions and methods now raise TypeError instead. The majority of the
1193 effects of this change are in the extension modules, but some core functions
1194 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1195 and many unicode/str methods.

1209 of integers: the result of a/b is now correctly rounded for ints a and b (at
1210 least on IEEE 754 platforms), and in particular does not depend on the
1211 internal representation of a long.

1219
Georg Brandlba83f822010-03-14 09:50:54 +00001220 These executables now work properly with the arch(1) command: ``arch -ppc
1221 python`` will start a universal binary version of python in PPC mode (unlike

1362 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001363
Georg Brandlba83f822010-03-14 09:50:54 +00001364- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1365 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001366

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001377
Georg Brandlba83f822010-03-14 09:50:54 +00001378- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1379 decimal string that's guaranteed to round back to x under correct rounding
1380 (with round-half-to-even rounding mode). Previously it gave a string based on
1381 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1382 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1383 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001384
Georg Brandlba83f822010-03-14 09:50:54 +00001385- Issue #7117: On almost all platforms: float-to-string and string-to-float
1386 conversions within Python are now correctly rounded. Places these conversions
1387 occur include: str for floats and complex numbers; the float and complex
1388 constructors; old-style and new-style numeric formatting; serialization and
1389 deserialization of floats and complex numbers using marshal, pickle and json;
1390 parsing of float and imaginary literals in Python code; Decimal-to-float
1391 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001392
Georg Brandlba83f822010-03-14 09:50:54 +00001393 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1394 providing correctly-rounded strtod and dtoa C functions. This code is
1395 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1396 the C compiler. There may be a small number of platforms on which correct
1397 operation of this code cannot be guaranteed, so the code is not used: notably,
1398 this applies to platforms where the C double format is not IEEE 754 binary64,
1399 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1400 and Python's configure script is unable to determine how to change the FPU
1401 precision. On these platforms conversions use the platform strtod and dtoa,
1402 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001404- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1405 uses the correctly-rounded string <-> float conversions described above (when
1406 available), and so produces correctly rounded results that will display nicely
1407 under the float repr. There are two related small changes: (1) round now
1408 accepts any class with an ``__index__()`` method for its second argument (but
1409 no longer accepts floats for the second argument), and (2) an excessively
1410 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1411 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001554 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1555 (2) parsing of strings representing infinities and nans was locale aware; and
1556 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001558- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1559 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1560 but with at least one decimal point and with a default precision
1561 of 12. Previously, the behavior the same but with a default precision of 6.
1562 This more closely matches ``str()``, and reduces surprises when adding
1563 alignment flags to the empty presentation type. This also affects the new
1564 complex.__format__ in the same way.
1565
1566- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00001747- Issue #4445: Replace ``sizeof(PyStringObject)`` with
1748 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1749 instances. On a typical machine this saves 3 bytes of memory (on average) per
1750 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00001752- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

1754 instead of throwing a MemoryError.
1755
Georg Brandlba83f822010-03-14 09:50:54 +00001756- Issue #3689: The list reversed iterator now supports __length_hint__ instead

1761
Georg Brandlba83f822010-03-14 09:50:54 +00001762- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1763 file objects with closefd=False. The file descriptor is still kept open but
1764 the file object behaves like a closed file. The ``FileIO`` object also got a
1765 new readonly attribute ``closefd``.

1784
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001785- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00001788- On windows, ``os.chdir()`` given unicode was not working if
1789 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1790 this code path is really executed because I cannot move to such directory on
1791 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001793- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1794 element is temporarily replaced with an equivalent frozenset. But the
1795 eventual KeyError would always report the empty ``frozenset()`` as the missing
1796 key. Now it correctly refers to the initial element.

1815
Walter Dörwalded960ac2009-05-03 22:36:33 +00001816- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1817 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1818 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1819 of using the replace error handler in PyUnicode_DecodeUTF8().
1820
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001821- Issue #3739: The unicode-internal encoder now reports the number of characters
1822 consumed like any other encoder (instead of the number of bytes).
1823
Georg Brandlba83f822010-03-14 09:50:54 +00001824- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1825 allocator will be automatically disabled when running under Valgrind. This
1826 gives improved memory leak detection when running under Valgrind, while taking
1827 advantage of pymalloc at other times.

Antoine Pitrou3c9f5412008-09-13 20:30:30 +00003173 AttributeError instead of RuntimeError, depending in which C API call
3174 exactly the recursion limit is exceeded. Consequently, both exception types

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003192- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3193
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003194- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3195 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3196 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3197 ``printf`` function, whereas PyString_FromFormat has an independent
3198 implementation and uses "%zd" on all platforms for size_t values.
3199 This makes a difference on win64, where ``printf`` needs "%Id" to display
3200 64bit values.
3201
Benjamin Peterson97179b02008-09-09 20:55:01 +00003202- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3206 object; previously an int would be returned for small values. the __long__
3207 method is allowed to return either an int or a long, but the behaviour of
3208 float objects should not change to respect backward compatibility.
3209
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003210- Issue #3751: str.rpartition would perform a left-partition when called with
3211 a unicode argument.
3212
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00003213- Issue #3683: Fix compilation when --without-threads is given.

Vinay Sajip35e3b032008-09-01 14:33:59 +00003216 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003217 was correctly parsed but parsing of subsequent arguments failed.
3218
Vinay Sajip35e3b032008-09-01 14:33:59 +00003219- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003220 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3221 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3222 when given a tuple of classes as second argument, were looking up
3223 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3224 type object.
3225
Neal Norwitz18aa3882008-08-24 05:04:52 +00003226- Fix crashes on memory allocation failure found with failmalloc.
3227
3228- Fix memory leaks found with valgrind and update suppressions file.
3229
3230- Fix compiler warnings in opt mode which would lead to invalid memory reads.
3231
3232- Fix problem using wrong name in decimal module reported by pychecker.

Gregory P. Smith980b99b2008-09-07 05:15:18 +00003243- Issue #1204: The configure script now tests for additional libraries
3244 that may be required when linking against readline. This fixes issues
3245 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Nick Coghland2e09382008-09-11 12:11:06 +00003268- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00003269 return a list or None rather than a custom object.
3270
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00003271- Issue #1638033: Cookie.Morsel gained the httponly attribute.

3295 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3296 for catch_warnings() also led to an improvement in the raising of a
3297 DeprecationWarning related to warnings.warn_explicit().

3369-----------------
3370
Guido van Rossumf8402962008-08-20 15:01:50 +00003371- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3372 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3373 extensions do not automatically benefit from the class attribute
3374 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3375 to their tp_flags field if they care. This is a backwards
3376 compatibility feature; in 3.0, all types will use the cache by
3377 default.
3378
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003379- Keyword arguments can now follow starred arguments. (``f(a, *args,
3380 keyword=23)`` is now valid syntax.)
3381
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003382- ctypes function pointers that are COM methods have a boolean True
3383 value again.
3384
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003385- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3386 by denying s# to parse objects that have a releasebuffer procedure,
3387 and introducing s*.
3388
Georg Brandl1e13ea92008-08-11 09:07:59 +00003389- Issue #3537: Fix an assertion failure when an empty but presized dict
3390 object was stored in the freelist.
3391
Mark Dickinsonb6467572008-08-04 21:30:09 +00003392- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3393 ValueError consistently across platforms.
3394
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003395- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3396 (64bit Unix, for example), unichr() would truncate its argument and return
3397 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3398
Neal Norwitze7d8be82008-07-31 17:17:14 +00003399- Apply security patches from Apple.
3400
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003401- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3402 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3403
Antoine Pitrou92f82162008-07-25 22:22:08 +00003404- Issue #1819: function calls with several named parameters are now on

Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003407- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3408 the python debugger steps into a class statement: the free variables (local
3409 variables defined in an outer scope) would be deleted from the outer scope.
3410
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003411- Issue #2620: Overflow checking when allocating or reallocating memory
3412 was not always being done properly in some python types and extension
3413 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3414 all been updated to perform better checks and places in the code that
3415 would previously leak memory on the error path when such an allocation
3416 failed have been fixed.

3422
Benjamin Petersone977ad42008-08-20 01:42:01 +00003423- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3424 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3425
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003426- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3427 version reported by these tools does not necessarily follow the python
3428 version numbering scheme, so the module is less strict when parsing it.
3429
Nick Coghlanf70385a2008-08-18 12:42:46 +00003430- Issue #2235: Added Py3k warnings for types which will become unhashable
3431 under the stricter __hash__ inheritance rules in 3.0. Several types
3432 which did not meet the rules for hash invariants and were already
3433 unhashable in 3.0 have now been explicitly flagged as unhashable in
3434 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3435 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3436
Brett Cannon88f801d2008-08-18 00:46:22 +00003437- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

3459 after a 302 response in the case of not going through a proxy.
3460
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003461- Issue #2676: in the email package, content-type parsing was hanging on
3462 pathological input because of quadratic or exponential behaviour of a
3463 regular expression.
3464

3466 thread-safe.
3467
Brett Cannonbf3157b2008-08-14 05:00:03 +00003468- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3469 since mimetools itself is deprecated. Because modules are cached, all
3470 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3471
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003472- Issue #3134: shutil referenced undefined WindowsError symbol.

3478 version that did not raise a DeprecationWarning under -3.
3479

3481 a MemoryError rather than silently stop the iteration.
3482
Guido van Rossum59ce9012008-08-09 14:55:34 +00003483- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3484 to _sre.compile() will now be rejected. This should not affect anybody
3485 since the re.compile() function never generates invalid re-bytecode.
3486
Skip Montanaroa032bf42008-08-08 22:52:51 +00003487- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3488 upon first access it can be automatically initialized from the csv file if
3489 it wasn't initialized during instantiation.
3490
Brett Cannon3aa2a492008-08-06 22:28:09 +00003491- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3492 the reload() built-in has been removed.
3493
Brett Cannon7e30b672008-08-04 21:52:25 +00003494- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003495 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3503 raised an AttributeError.
3504
Benjamin Peterson01a24322008-07-28 23:35:27 +00003505- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003506 asking for a specific length. This problem only affected files opened
3507 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003508

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003532- Issue #3394: zipfile.writestr sets external attributes when passed a
3533 file name rather than a ZipInfo instance, so files are extracted with
3534 mode 0600 rather than 000 under Unix.
3535
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003536- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3537 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00003548- Issue #2235: the C API function PyObject_HashNotImplemented and its
3549 interaction with the tp_hash slot (added in 2.6b2) are now documented
3550
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003551- Issue #643841: The language reference now provides more detailed
3552 coverage of the lookup process for special methods. The disclaimers
3553 regarding lack of coverage of new-style classes have also been
3554 removed, since the coverage is now fairly reasonable.

3558================================
3559
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003560*Release date: 17-Jul-2008*
3561
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003562Core and Builtins
3563-----------------
3564
Georg Brandl3e483f62008-07-16 22:57:41 +00003565- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3566 its methods now allow for items objects that can be converted to
3567 an integer using operator.index().
3568
Mark Dickinson64b7e502008-07-16 09:40:03 +00003569- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3570 produced a ValueError instead of giving the correct float.
3571
Eric Smitha5fa5a22008-07-16 00:11:49 +00003572- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3573 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3574
Mark Dickinson7103aa42008-07-15 19:08:33 +00003575- Issue #3008: the float type has a new instance method 'float.hex'
3576 and a new class method 'float.fromhex' to convert floating-point
3577 numbers to and from hexadecimal strings, respectively.
3578
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003579- Issue #2235: __hash__ is once again inherited by default. To allow
3580 collections.Hashable to remain meaningful in the presence of the
3581 default hash implementation (object.__hash__), it is now possible
3582 to explicit block inheritance of hash by setting __hash__=None at
3583 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3584 level.
3585
Nick Coghlanb028f502008-07-13 14:52:36 +00003586- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3587 the parent module cannot be found while performing an absolute import.
3588 This means that an incorrectly defined __package__ attribute will
3589 now only prevent relative imports in that module rather than causing
3590 all imports from that module to fail.
3591
Nick Coghlan14ff9942008-07-08 14:21:42 +00003592- Issue #2517: Allow unicode messages in Exceptions again by correctly
3593 bypassing the instance dictionary when looking up __unicode__ on
3594 new-style classes.
3595
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003596- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3597 set to a custom object whose write() method happens to install
3598 another file in sys.stdout.
3599
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003600- Issue #3088: Corrected a race condition in classes derived from
3601 threading.local: the first member set by a thread could be saved in
3602 another thread's dictionary.
3603
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003604- Issue #3004: Minor change to slice.indices(): the start and stop
3605 arguments are now treated identically, making the behaviour easier
3606 to describe and understand. For example, slice(None, -10,
3607 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3608 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3609 10, -1).
3610
Georg Brandl278fc502008-07-19 12:46:12 +00003611- Issue #3219: Calling a function with repeated keyword arguments,
3612 f(a=2, a=23), would not cause a syntax error. This was a regression
3613 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003614
Georg Brandl278fc502008-07-19 12:46:12 +00003615- Issue #2862: Make int and float freelist management consistent with
3616 other freelists. Changes their CompactFreeList apis into
3617 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00003618

3620-------
3621
Thomas Heller57adf222008-08-14 19:10:48 +00003622- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3623 api functions without holding the GIL, which could lead to a fatal
3624 error when they failed.
3625
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003626- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00003634- Issue #3125: Remove copy_reg in multiprocessing and replace it with
3635 ForkingPickler.register() to resolve conflict with ctypes.
3636
Vinay Sajip51e65192008-07-18 09:01:10 +00003637- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00003638
Thomas Heller880f5292008-07-15 19:39:38 +00003639- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3640 a valid dlerror() message.
3641
Thomas Heller2bad6572008-07-15 17:19:50 +00003642- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3643 incomplete structure was created.
3644
Brett Cannon3d0b9f02008-07-13 01:15:07 +00003645- Issue #3339: dummy_thread.acquire() should not return None.

Raymond Hettingerb01713e2008-07-10 14:34:57 +00003647- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
3648
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003649- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003650
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003651- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3652 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003653 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003654 content-length. The problem had been corrected in the 2.4 branch, but never
3655 merged into trunk.
3656
Georg Brandle78fbcc2008-07-05 10:13:36 +00003657- Issue #2663: add filtering capability to shutil.copytree().

Vinay Sajip51e65192008-07-18 09:01:10 +00003667- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003668 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00003669
Nick Coghlanc060b0e2008-07-02 13:09:19 +00003670- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3671 handling is now the same as that of other special attributes like __name__).
3672
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003673- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
3674 removal in Python 3.0 in favor of urllib2.urlopen().

3685 default https port (443).
3686
Gregory P. Smithdb3409c2008-07-17 03:13:05 +00003687- Issue #874900: after an os.fork() call the threading module state is cleaned

Georg Brandl5cc774e2008-06-11 20:28:06 +00004063 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004064
4065 This is controlled by the configure argument ``--with-universal-archs``:
4066
4067 - ``--with-universal-archs=all``: install 4-way universal
4068
4069 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4070
4071 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4072
4073 This option should be used in combination with ``--enable-universalsdk=``.
4074
4075 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 +00004125- Issue #1631171: Re-implement the 'warnings' module in C (the
4126 original Python code has been kept as backup). This will allow for
4127 using the 'warning's machinery in such places as the parser where
4128 use of pure Python code is not possible. Both the ``showarning()``
4129 and ``formatwarning()`` gain an optional 'line' argument which is
4130 not called by default for backwards-compatibility reasons. Setting
4131 ``warnings.showwarning()`` to an implementation that lacks support
4132 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004195- Issue #2550: The approach used by client/server code for obtaining
4196 ports to listen on in network-oriented tests has been refined in an
4197 effort to facilitate running multiple instances of the entire
4198 regression test suite in parallel without issue.
4199 test_support.bind_port() has been fixed such that it will always
4200 return a unique port -- which wasn't always the case with the
4201 previous implementation, especially if socket options had been set
4202 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4203 new implementation of bind_port() will actually raise an exception
4204 if it is passed an AF_INET/SOCK_STREAM socket with either the
4205 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4206 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4207 the socket it's been passed. This currently only applies to
4208 Windows. This option prevents any other sockets from binding to the
4209 host/port we've bound to, thus removing the possibility of the
4210 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4211 when a second SOCK_STREAM socket binds and accepts to a host/port
4212 that's already been bound by another socket. The optional preferred
4213 port parameter to bind_port() has been removed. Under no
4214 circumstances should tests be hard coding ports!
4215
4216 test_support.find_unused_port() has also been introduced, which will
4217 pass a temporary socket object to bind_port() in order to obtain an
4218 unused port. The temporary socket object is then closed and
4219 deleted, and the port is returned. This method should only be used
4220 for obtaining an unused port in order to pass to an external program
4221 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4222 a parameter to a server-oriented class that doesn't give you direct
4223 access to the underlying socket used.
4224
4225 Finally, test_support.HOST has been introduced, which should be used
4226 for the host argument of any relevant socket calls (i.e. bind and
4227 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004228
4229 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004230 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004231 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4232 test_asynchat and test_socket_ssl.
4233
Georg Brandl3ee81df2008-05-17 18:14:43 +00004234 It is now possible for multiple instances of the regression test

Fred Drakea8ee94b2008-03-01 02:45:07 +00004504- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004505 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004506
Georg Brandlad61bc82008-02-23 15:11:18 +00004507- Issue #2067: file.__exit__() now calls subclasses' close() method.
4508
4509- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004510
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004511- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004512 issue 215555 for a discussion.
4513
Eric Smitha73fbe72008-02-23 03:09:44 +00004514- Added the future_builtins module, which contains hex() and oct().
4515 These are the PEP 3127 version of these functions, designed to be
4516 compatible with the hex() and oct() builtins from Python 3.0. They
4517 differ slightly in their output formats from the existing, unchanged
4518 Python 2.6 builtins. The expected usage of the future_builtins
4519 module is:
4520 from future_builtins import hex, oct
4521
Eric Smith7ef40bf2008-02-20 23:34:22 +00004522- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4523 exponents for exponents with absolute value < 100. Follows C99
4524 standard. This is a change on Windows, which would use 3 digits.
4525 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4526 so that any alterations it does to the resulting string will be
4527 available in stringlib/formatter.h (for float.__format__).
4528
Eric Smith5a3c1352008-02-19 13:21:56 +00004529- Implemented PEP 3101, Advanced String Formatting. This adds a new
4530 builtin format(); a format() method for str and unicode; a
4531 __format__() method to object, str, unicode, int, long, float, and
4532 datetime; the class string.Formatter; and the C API
4533 PyObject_Format().
4534
Georg Brandl3ee81df2008-05-17 18:14:43 +00004535- Fixed several potential crashes, all caused by specially crafted
4536 __del__ methods exploiting objects in temporarily inconsistent
4537 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004538
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004539- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004540 prevent a possible crash: an Abstract Base Class would try to access
4541 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004542
Georg Brandl3ee81df2008-05-17 18:14:43 +00004543- Fixed repr() and str() of complex numbers with infinity or nan as
4544 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004545
Georg Brandl3ee81df2008-05-17 18:14:43 +00004546- Clear all free lists during a gc.collect() of the highest generation
4547 in order to allow pymalloc to free more arenas. Python may give back
4548 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004549
Georg Brandl3ee81df2008-05-17 18:14:43 +00004550- Issue #2045: Fix an infinite recursion triggered when printing a
4551 subclass of collections.defaultdict, if its default_factory is set
4552 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004553
Christian Heimesf75dbef2008-02-08 00:11:31 +00004554- Fixed a minor memory leak in dictobject.c. The content of the free
4555 list was not freed on interpreter shutdown.
4556
Georg Brandl21e99f42010-03-07 15:23:59 +00004557- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004558 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004559
Georg Brandl3ee81df2008-05-17 18:14:43 +00004560- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4561 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004562 to compact the internal free lists of pre-allocted ints and floats.
4563
Georg Brandl3ee81df2008-05-17 18:14:43 +00004564- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4565 calls. Python expected the return type int but the fork familie
4566 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004567
Georg Brandl3ee81df2008-05-17 18:14:43 +00004568- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4569 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004570
Georg Brandl3ee81df2008-05-17 18:14:43 +00004571- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4572 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004573
Georg Brandl3ee81df2008-05-17 18:14:43 +00004574- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4575 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004576
Georg Brandl3ee81df2008-05-17 18:14:43 +00004577- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4578 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004579
Georg Brandl3ee81df2008-05-17 18:14:43 +00004580- Patch #1473257: generator objects gain a gi_code attribute. This is
4581 the same object as the func_code attribute of the function that
4582 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004583
Georg Brandl3ee81df2008-05-17 18:14:43 +00004584- Issue #1920: "while 0" statements were completely removed by the
4585 compiler, even in the presence of an "else" clause, which is
4586 supposed to be run when the condition is false. Now the compiler
4587 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004588
Guido van Rossumeead05f2008-01-24 18:21:02 +00004589- A few crashers fixed: weakref_in_del.py (issue #1377858);
4590 loosing_dict_ref.py (issue #1303614, test67.py);
4591 borrowed_ref_[34].py (not in tracker).
4592
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004593- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004594 suppressed while an extension is loaded by calling SetErrorMode in
4595 dynload_win.c. The error is still reported properly.
4596
Georg Brandl3ee81df2008-05-17 18:14:43 +00004597- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004598 several extension methods and modules do not work without unicode
4599 support.
4600
Georg Brandl26543b12008-01-21 18:36:51 +00004601- Issue #1882: when compiling code from a string, encoding cookies in the
4602 second line of code were not always recognized correctly.
4603
Georg Brandl14404b62008-01-19 19:27:05 +00004604- Issue #1679: "0x" was taken as a valid integer literal.
4605
Georg Brandl6caad7d2008-01-26 14:19:22 +00004606- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004607 added.
4608
Christian Heimesc94e2b52008-01-14 04:13:37 +00004609- sys.float_info / PyFloat_GetInfo: The floating point information
4610 object was converted from a dict to a specialized structseq object.
4611
Georg Brandl3ee81df2008-05-17 18:14:43 +00004612- Patch #1816: Added sys.flags structseq. It exposes the status of
4613 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004614
Georg Brandl3ee81df2008-05-17 18:14:43 +00004615- Objects/structseq.c: Implemented new structseq representation. The
4616 patch makes structseqs (e.g. the return value of os.stat) more
4617 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004618
Georg Brandl3ee81df2008-05-17 18:14:43 +00004619- Patch #1700288: added a type attribute cache that caches method
4620 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004621
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004622- Bug #1776: __import__() no longer accepts filenames on any platform.
4623 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004624

4626
Georg Brandl3ee81df2008-05-17 18:14:43 +00004627- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4628 envvar and sys.dont_write_bytecode attribute. All these can be set
4629 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004630
Georg Brandl3ee81df2008-05-17 18:14:43 +00004631- Improve some exception messages when Windows fails to load an
4632 extension module. Now we get for example '%1 is not a valid Win32
4633 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004634
Georg Brandl3ee81df2008-05-17 18:14:43 +00004635- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004637- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4638 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004639
Christian Heimes0a8143f2007-12-18 23:22:54 +00004640- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004641 and INF. float("nan"), float("inf") and float("-inf") now work on
4642 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004643
Georg Brandl3ee81df2008-05-17 18:14:43 +00004644- Compiler now generates simpler and faster code for dictionary
4645 literals. The oparg for BUILD_MAP now indicates an estimated
4646 dictionary size. There is a new opcode, STORE_MAP, for adding
4647 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004648
Georg Brandl3ee81df2008-05-17 18:14:43 +00004649- Issue #1638: %zd configure test fails on Linux.

4677 file can now be directly executed by passing their name to the
4678 interpreter. The directory/zipfile is automatically inserted as the
4679 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004680
Georg Brandl3ee81df2008-05-17 18:14:43 +00004681- Issue #1265: Fix a problem with sys.settrace, if the tracing
4682 function uses a generator expression when at the same time the
4683 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004684
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004685- sets and frozensets now have an isdisjoint() method.
4686
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004687- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00004689- Fix warnings found by the new version of the Coverity checker.
4690
Georg Brandl21e99f42010-03-07 15:23:59 +00004691- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004692 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4693 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004694
Georg Brandl3ee81df2008-05-17 18:14:43 +00004695- Issue #1686386: Tuple's tp_repr did not take into account the
4696 possibility of having a self-referential tuple, which is possible
4697 from C code. Nor did object's tp_str consider that a type's tp_str
4698 could do something that could lead to an inifinite recursion.
4699 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4700 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004701
Georg Brandl3ee81df2008-05-17 18:14:43 +00004702- Issue #1164: It was possible to trigger deadlock when using the
4703 'print' statement to write to a file since the GIL was not released
4704 as needed. Now PyObject_Print() does the right thing along with
4705 various tp_print implementations of the built-in types and those in
4706 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004707
Georg Brandl3ee81df2008-05-17 18:14:43 +00004708- Issue #1147: Exceptions were directly allowing string exceptions in
4709 their throw() method even though string exceptions no longer
4710 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004711

Brett Cannon1e534b52007-09-07 04:18:30 +00004715- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004716 PyObject_Call() never calling back out to Python code to trigger
4717 recursion depth updates/checks. Required the creation of a static
4718 RuntimeError instance in case normalizing an exception put the
4719 recursion check value past its limit. Fixes crashers
4720 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004721

Neal Norwitz0ac60192007-05-27 04:08:54 +00004735- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004736 __*__ attributes. (Some already existed, e.g., __doc__ and
4737 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004738
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004739- Add -3 option to the interpreter to warn about features that are
4740 deprecated and will be changed/removed in Python 3.0.
4741
Georg Brandl2134e752007-05-21 20:34:16 +00004742- Patch #1686487: you can now pass any mapping after '**' in function
4743 calls.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004746 "except E as target:". This is to provide forwards compatibility
4747 with Python 3.0.

Guido van Rossum143b5642007-03-23 04:58:42 +00004768- Bug #1683368: The object.__init__() and object.__new__() methods are
4769 now stricter in rejecting excess arguments. The only time when
4770 either allows excess arguments is when it is not overridden and the
4771 other one is. For backwards compatibility, when both are
4772 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004773 warning later). Also, type.__init__() insists on the same signature
4774 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004776- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4777 object to complex using its __complex__() method before falling back
4778 to the __float__() method. Therefore, the functions in the cmath
4779 module now can operate on objects that define a __complex__()
4780 method.

4800
Georg Brandl871f1bc2007-03-12 13:17:36 +00004801- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004802 its argument, if it exists. If not, it will work like before. This
4803 allows customizing the output of dir() in the presence of a

4814 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00004816- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004817 makes the filenames the warning module prints much more sensible
4818 when a PYTHONSTARTUP file is used.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005369 AttributeError instead of an IOError when the server's response

5461 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00005746- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5747 with RFC 3207 and forgets any knowledge obtained from the server not
5748 obtained from the TLS negotiation itself. Patch contributed by Bill
5749 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005750
Georg Brandl3ee81df2008-05-17 18:14:43 +00005751- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005752 that the SMTP.starttls() caller no longer needs to call ehlo()
5753 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005754 does not claim to support starttls. Adds the
5755 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5836 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5837 silently miscode subclasses of those types. Now, it raises a
5838 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005839

Georg Brandl3ee81df2008-05-17 18:14:43 +00005854 time so that opening a database previously created with the DB_DUP
5855 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5856 opens. Specifically: dictionary assignment to a DB object will
5857 replace all values for a given key when the database allows
5858 duplicate values. DB users should use DB.put(k, v) when they want
5859 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005860

5866 characters with ASCII value less than 32. Also, it correctly quotes
5867 dots only if they occur on a single line, as opposed to the previous
5868 behavior of quoting dots if they are the second character of any
5869 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005870

Georg Brandl3ee81df2008-05-17 18:14:43 +00006214- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6215 of w# format code incorrectly truncated the length to an int, even
6216 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6217 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006219- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
6220 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006226- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
6227 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006228
6229- Patch #1733960: Allow T_LONGLONG to accept ints.
6230
6231- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.

6236
6237- Fix some leftovers from the conversion from int to Py_ssize_t
6238 (relevant to strings and sequences of more than 2**31 items).
6239
6240- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6241 outside of pystate.c and should not be necessary.
6242
Georg Brandl3ee81df2008-05-17 18:14:43 +00006243- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6244 absolute imports. In earlier versions they might have used relative
6245 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006246
Georg Brandl3ee81df2008-05-17 18:14:43 +00006247- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6248 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006249
Georg Brandl3ee81df2008-05-17 18:14:43 +00006250- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00006257- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
6258 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6259 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6260 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006275- Removed the macfs module. It had been deprecated since Python 2.5.
6276 This lead to the deprecation of macostools.touched() as it relied
6277 solely on macfs and was a no-op under OS X.
