Florent Xiclunac2279652012-02-12 14:49:03 +0100629- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100630 has left two versions of customize_compiler, the original in
631 distutils.sysconfig and another copy in distutils.ccompiler, with some
632 parts of distutils calling one and others using the other.
633 Complete the revert back to only having one in distutils.sysconfig as
634 is the case in 3.x.
635
Ned Deily0d0ea482012-02-10 12:59:06 +0100636- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
637 Distutils-based packages with C extension modules may fail because
638 Apple has removed gcc-4.2, the version used to build python.org
639 64-bit/32-bit Pythons. If the user does not explicitly override
640 the default C compiler by setting the CC environment variable,
641 Distutils will now attempt to compile extension modules with clang
642 if gcc-4.2 is required but not found. Also as a convenience, if
643 the user does explicitly set CC, substitute its value as the default
644 compiler in the Distutils LDSHARED configuration variable for OS X.
645 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
646 SDK, neither of which are available in Xcode 4. This change does not
647 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700920- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
921 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
922 interpreter process. This could cause failures in non-Distutils subprocesses
923 and was unreliable since tests or user programs could modify the interpreter
924 environment after Distutils set it. Instead, have Distutils set the the
925 deployment target only in the environment of each build subprocess. It is
926 still possible to globally override the default by setting
927 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
928 greater or equal to the default value, the value with which the interpreter
929 was built.

959 the ticker doesn't have to wind down to zero from the old starting point
960 before the new interval takes effect. And if the user increases the
961 interval, it makes sure the new limit takes effect right away rather have an
962 early task switch before recognizing the new interval.

1914 This prevents user-created self-referencing ordered dictionaries from
1915 becoming permanently uncollectable GC garbage. The downside is that

2375-----------------
2376
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002377- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2378 start byte and the continuation byte(s) are now considered invalid, instead
2379 of the number of bytes specified by the start byte.
2380 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2381 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2382 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2383 Previous versions returned a single u'\ufffd'.

Mark Dickinson23f0d6b2010-06-05 11:52:24 +00002385- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00002386 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
2387 arises from the "Overriding __eq__ blocks inheritance ..." warning
2388 when turned into an exception: in this case the exception simply
2389 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002391- Issue #8748: Fix two issues with comparisons between complex and integer
2392 objects. (1) The comparison could incorrectly return True in some cases
2393 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2394 (2) The comparison raised an OverflowError for large integers, leading
2395 to unpredictable exceptions when combining integers and complex objects
2396 in sets or dicts.
2397
Mark Dickinson81336372010-05-30 12:12:25 +00002398- Issue #5211: Implicit coercion for the complex type is now completely
2399 removed. (Coercion for arithmetic operations was already removed in 2.7
2400 alpha 4, but coercion for rich comparisons was accidentally left in.)
2401
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00002402- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

2404
Georg Brandlfee0f442010-05-22 21:26:21 +00002405- Issue #7902: When using explicit relative import syntax, don't try implicit

2779 with a non-empty format string. This is an effort to future-proof user
2780 code. If a derived class does not currently implement __format__ but later
2781 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002782 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002783 Python 3.3 and it will be an error in Python 3.4.

2840 returned an arbitrary result based on the relative ordering of id(float) and
2841 id(Decimal).

Antoine Pitroud840e512010-02-04 20:20:18 +00003268- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00003269 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Georg Brandlba83f822010-03-14 09:50:54 +00003276 file position when calling `truncate()`. It would previously change the file
3277 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003278 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3279

3281 class used to represent files stored inside an archive. The new
3282 implementation is significantly faster and can be wrapped in a

3284 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

3297 encoded string for them. This ensures that the upload and register commands
3298 send the correct values to PyPI without any error.

3373-----------------
3374
Georg Brandlba83f822010-03-14 09:50:54 +00003375- The ``__complex__()`` method is now looked up on the class of instances to
3376 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00003378- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,

3380
Mark Dickinson1b34d252010-01-01 17:27:30 +00003381- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003382 DeprecationWarning when passed a float argument where an integer was expected.
3383 These functions and methods now raise TypeError instead. The majority of the
3384 effects of this change are in the extension modules, but some core functions
3385 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3386 and many unicode/str methods.

3400 of integers: the result of a/b is now correctly rounded for ints a and b (at
3401 least on IEEE 754 platforms), and in particular does not depend on the
3402 internal representation of a long.

3410
Georg Brandlba83f822010-03-14 09:50:54 +00003411 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00003548- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
3549 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003550
Georg Brandlba83f822010-03-14 09:50:54 +00003551- Issue #3382: 'F' formatting for float and complex now convert the result to
3552 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
3553 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003554
Georg Brandlba83f822010-03-14 09:50:54 +00003555- Remove switch from "%f" formatting to "%g" formatting for floats larger than
3556 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00003557
Georg Brandlba83f822010-03-14 09:50:54 +00003558- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
3559 1e-100 used to raise OverflowError, but now gives the requested 120
3560 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00003561
Georg Brandlba83f822010-03-14 09:50:54 +00003562- Add Py3k warnings for parameter names in parentheses.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +00003563
Georg Brandlba83f822010-03-14 09:50:54 +00003564- Issue #7362: Give a proper error message for ``def f((x)=3): pass``.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +00003565
Georg Brandlba83f822010-03-14 09:50:54 +00003566- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
3567 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003568
Georg Brandlba83f822010-03-14 09:50:54 +00003569- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3570 decimal string that's guaranteed to round back to x under correct rounding
3571 (with round-half-to-even rounding mode). Previously it gave a string based on
3572 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3573 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3574 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003575
Georg Brandlba83f822010-03-14 09:50:54 +00003576- Issue #7117: On almost all platforms: float-to-string and string-to-float
3577 conversions within Python are now correctly rounded. Places these conversions
3578 occur include: str for floats and complex numbers; the float and complex
3579 constructors; old-style and new-style numeric formatting; serialization and
3580 deserialization of floats and complex numbers using marshal, pickle and json;
3581 parsing of float and imaginary literals in Python code; Decimal-to-float
3582 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003583
Georg Brandlba83f822010-03-14 09:50:54 +00003584 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3585 providing correctly-rounded strtod and dtoa C functions. This code is
3586 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3587 the C compiler. There may be a small number of platforms on which correct
3588 operation of this code cannot be guaranteed, so the code is not used: notably,
3589 this applies to platforms where the C double format is not IEEE 754 binary64,
3590 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3591 and Python's configure script is unable to determine how to change the FPU
3592 precision. On these platforms conversions use the platform strtod and dtoa,
3593 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003594
Georg Brandlba83f822010-03-14 09:50:54 +00003595- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3596 uses the correctly-rounded string <-> float conversions described above (when
3597 available), and so produces correctly rounded results that will display nicely
3598 under the float repr. There are two related small changes: (1) round now
3599 accepts any class with an ``__index__()`` method for its second argument (but
3600 no longer accepts floats for the second argument), and (2) an excessively
3601 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3602 raises an exception.
Mark Dickinsonbd15a062009-11-18 19:33:35 +00003603
Philip Jenveyfab8be22009-11-17 02:42:26 +00003604- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
3605
Georg Brandlba83f822010-03-14 09:50:54 +00003606- Fix several issues with ``compile()``. The input can now contain Windows and
3607 Mac newlines and is no longer required to end in a newline.
Benjamin Petersone36199b2009-11-12 23:39:44 +00003608
Georg Brandlba83f822010-03-14 09:50:54 +00003609- Remove length limitation when constructing a complex number from a unicode
3610 string.
Mark Dickinsonc04c7c52009-10-26 22:28:14 +00003611
Georg Brandlba83f822010-03-14 09:50:54 +00003612- Issue #7244: ``itertools.izip_longest()`` no longer ignores exceptions raised
3613 during the formation of an output tuple.
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +00003614
Mark Dickinson8d87dc02009-10-25 20:39:06 +00003615- Issue #1087418: Boost performance of bitwise operations for longs.
3616
Georg Brandlba83f822010-03-14 09:50:54 +00003617- Issue #1722344: ``threading._shutdown()`` is now called in ``Py_Finalize()``,
3618 which fixes the problem of some exceptions being thrown at shutdown when the
3619 interpreter is killed. Patch by Adam Olsen.

Georg Brandlba83f822010-03-14 09:50:54 +00003621- Issue #7168: Document ``PyFloat_AsString()`` and ``PyFloat_AsReprString()``,
3622 and note that they are unsafe and deprecated.
Eric Smithc12781a2009-10-19 14:38:14 +00003623

Georg Brandlba83f822010-03-14 09:50:54 +00003627- Issue #7140: The ``__dict__`` of a module should not be cleared unless the
3628 module is the only object holding a reference to it.
Benjamin Peterson196b0922009-10-15 15:44:46 +00003629
Georg Brandlba83f822010-03-14 09:50:54 +00003630- Issue #1754094: Improve the stack depth calculation in the compiler. There
3631 should be no other effect than a small decrease in memory use. Patch by
3632 Christopher Tur Lesniewski-Laas.
Neil Schemenauer7fdd1cb2009-10-14 17:17:14 +00003633
Georg Brandlba83f822010-03-14 09:50:54 +00003634- Issue #7084: Fix a (very unlikely) crash when printing a list from one thread,
3635 and mutating it from another one. Patch by Scott Dial.
Antoine Pitroubeaf6a02009-10-11 21:03:26 +00003636
Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +00003637- Issue #1571184: The Unicode database contains properties for more characters.
3638 The tables for code points representing numeric values, white spaces or line
3639 breaks are now generated from the official Unicode Character Database files,
3640 and include information from the Unihan.txt file.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00003744
Georg Brandlba83f822010-03-14 09:50:54 +00003745 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3746 (2) parsing of strings representing infinities and nans was locale aware; and

Georg Brandlba83f822010-03-14 09:50:54 +00003749- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3750 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3751 but with at least one decimal point and with a default precision
3752 of 12. Previously, the behavior the same but with a default precision of 6.
3753 This more closely matches ``str()``, and reduces surprises when adding
3754 alignment flags to the empty presentation type. This also affects the new
3755 complex.__format__ in the same way.
3756
3757- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Walter Dörwalded960ac2009-05-03 22:36:33 +00004007- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4008 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

4017 gives improved memory leak detection when running under Valgrind, while taking
4018 advantage of pymalloc at other times.

5184 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
5185 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
5186 neither __int__ nor __long__, TypeError used to be raised (with a

Georg Brandlba83f822010-03-14 09:50:54 +00005241 leak-chasing test runs give sensible results. The previous method of reaping
5242 threads could return successfully while some Thread objects were still
5243 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00005244
Georg Brandlba83f822010-03-14 09:50:54 +00005245- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer

5261 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00005262 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005385- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

5387 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5388 ``printf`` function, whereas PyString_FromFormat has an independent
5389 implementation and uses "%zd" on all platforms for size_t values.
5390 This makes a difference on win64, where ``printf`` needs "%Id" to display

5399 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005401- Issue #3751: str.rpartition would perform a left-partition when called with
5402 a unicode argument.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005406- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00005407 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005408 was correctly parsed but parsing of subsequent arguments failed.
5409
Vinay Sajip35e3b032008-09-01 14:33:59 +00005410- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005411 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5412 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5413 when given a tuple of classes as second argument, were looking up
5414 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5415 type object.
5416
Neal Norwitz18aa3882008-08-24 05:04:52 +00005417- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005486 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5487 for catch_warnings() also led to an improvement in the raising of a
5488 DeprecationWarning related to warnings.warn_explicit().
5489

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005554What's New in Python 2.6 beta 3?
5555================================
5556
Barry Warsaw07a4a382008-08-21 01:15:08 +00005557*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005558
5559Core and Builtins
5560-----------------
5561
Guido van Rossumf8402962008-08-20 15:01:50 +00005562- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5563 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5564 extensions do not automatically benefit from the class attribute
5565 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5566 to their tp_flags field if they care. This is a backwards
5567 compatibility feature; in 3.0, all types will use the cache by
5568 default.
5569
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005570- Keyword arguments can now follow starred arguments. (``f(a, *args,
5571 keyword=23)`` is now valid syntax.)
5572
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005573- ctypes function pointers that are COM methods have a boolean True
5574 value again.
5575
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005576- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5577 by denying s# to parse objects that have a releasebuffer procedure,
5578 and introducing s*.
5579
Georg Brandl1e13ea92008-08-11 09:07:59 +00005580- Issue #3537: Fix an assertion failure when an empty but presized dict
5581 object was stored in the freelist.
5582
Mark Dickinsonb6467572008-08-04 21:30:09 +00005583- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5584 ValueError consistently across platforms.
5585
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005586- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5587 (64bit Unix, for example), unichr() would truncate its argument and return
5588 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5589
Neal Norwitze7d8be82008-07-31 17:17:14 +00005590- Apply security patches from Apple.
5591
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005592- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5593 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5594
Antoine Pitrou92f82162008-07-25 22:22:08 +00005595- Issue #1819: function calls with several named parameters are now on
5596 average 35% faster (as measured by pybench).
5597
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005598- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5599 the python debugger steps into a class statement: the free variables (local
5600 variables defined in an outer scope) would be deleted from the outer scope.
5601
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005602- Issue #2620: Overflow checking when allocating or reallocating memory
5603 was not always being done properly in some python types and extension
5604 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5605 all been updated to perform better checks and places in the code that
5606 would previously leak memory on the error path when such an allocation
5607 failed have been fixed.

5610-------
5611
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005612- Issue #3612: Added some missing basic types in ctypes.wintypes.
5613
Benjamin Petersone977ad42008-08-20 01:42:01 +00005614- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5615 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5616
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005617- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5618 version reported by these tools does not necessarily follow the python
5619 version numbering scheme, so the module is less strict when parsing it.
5620
Nick Coghlanf70385a2008-08-18 12:42:46 +00005621- Issue #2235: Added Py3k warnings for types which will become unhashable
5622 under the stricter __hash__ inheritance rules in 3.0. Several types
5623 which did not meet the rules for hash invariants and were already
5624 unhashable in 3.0 have now been explicitly flagged as unhashable in
5625 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5626 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5627
Brett Cannon88f801d2008-08-18 00:46:22 +00005628- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5629 imported into the module but exposed as part of the module's API.
5630
Brett Cannon7b96f072008-08-18 00:41:11 +00005631- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5632
Brett Cannon46225e72008-08-18 00:36:52 +00005633- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005635- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5636
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005637- Issue #3575: Incremental decoder's decode function now takes bytearray
5638 by using 's*' instead of 't#'.
5639
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005640- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005641 fails unicode conversion on 2nd parameter. (windows only)
5642
Georg Brandl222e2082010-08-01 22:27:39 +00005643- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005644 in a redirect.
5645
Brett Cannonabe423e2008-08-16 21:47:07 +00005646- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005647 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005648
Facundo Batistaeb90b782008-08-16 14:44:07 +00005649- Issue #2776: fixed small issue when handling an URL with double slash
5650 after a 302 response in the case of not going through a proxy.
5651
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005652- Issue #2676: in the email package, content-type parsing was hanging on
5653 pathological input because of quadratic or exponential behaviour of a
5654 regular expression.
5655
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005656- Issue #3476: binary buffered reading through the new "io" library is now
5657 thread-safe.
5658
Brett Cannonbf3157b2008-08-14 05:00:03 +00005659- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5660 since mimetools itself is deprecated. Because modules are cached, all
5661 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5662
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005663- Issue #3134: shutil referenced undefined WindowsError symbol.
5664
Robert Schuppenies14646332008-08-10 11:01:53 +00005665- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5666 menu entries were not deleted.
5667
Brett Cannon83e81842008-08-09 23:30:55 +00005668- Copied the implementation of reduce() to _functools.reduce() to have a
5669 version that did not raise a DeprecationWarning under -3.
5670
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005671- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5672 a MemoryError rather than silently stop the iteration.
5673
Guido van Rossum59ce9012008-08-09 14:55:34 +00005674- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5675 to _sre.compile() will now be rejected. This should not affect anybody
5676 since the re.compile() function never generates invalid re-bytecode.
5677
Skip Montanaroa032bf42008-08-08 22:52:51 +00005678- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5679 upon first access it can be automatically initialized from the csv file if
5680 it wasn't initialized during instantiation.
5681
Brett Cannon3aa2a492008-08-06 22:28:09 +00005682- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as

5754-----------------
5755
Georg Brandl3e483f62008-07-16 22:57:41 +00005756- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5757 its methods now allow for items objects that can be converted to
5758 an integer using operator.index().
5759
Mark Dickinson64b7e502008-07-16 09:40:03 +00005760- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5761 produced a ValueError instead of giving the correct float.
5762
Eric Smitha5fa5a22008-07-16 00:11:49 +00005763- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5764 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5765
Mark Dickinson7103aa42008-07-15 19:08:33 +00005766- Issue #3008: the float type has a new instance method 'float.hex'
5767 and a new class method 'float.fromhex' to convert floating-point
5768 numbers to and from hexadecimal strings, respectively.
5769
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005770- Issue #2235: __hash__ is once again inherited by default. To allow
5771 collections.Hashable to remain meaningful in the presence of the
5772 default hash implementation (object.__hash__), it is now possible
5773 to explicit block inheritance of hash by setting __hash__=None at
5774 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5775 level.
5776
Nick Coghlanb028f502008-07-13 14:52:36 +00005777- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5778 the parent module cannot be found while performing an absolute import.
5779 This means that an incorrectly defined __package__ attribute will
5780 now only prevent relative imports in that module rather than causing
5781 all imports from that module to fail.
5782
Nick Coghlan14ff9942008-07-08 14:21:42 +00005783- Issue #2517: Allow unicode messages in Exceptions again by correctly

5793 another thread's dictionary.
5794
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005795- Issue #3004: Minor change to slice.indices(): the start and stop
5796 arguments are now treated identically, making the behaviour easier
5797 to describe and understand. For example, slice(None, -10,
5798 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5799 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5800 10, -1).
5801
Georg Brandl278fc502008-07-19 12:46:12 +00005802- Issue #3219: Calling a function with repeated keyword arguments,
5803 f(a=2, a=23), would not cause a syntax error. This was a regression
5804 from 2.4 caused by the switch to the new compiler.

5807 other freelists. Changes their CompactFreeList apis into

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005842- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5843 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005844 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005845 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005861- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

6249
Brett Cannonb61d8012008-05-11 23:39:04 +00006250- ``Lib/lib-old`` is now added to sys.path.
6251
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006252- On MacOS X it is now possible to install the framework in 64-bit
6253 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006254 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006255
6256 This is controlled by the configure argument ``--with-universal-archs``:
6257
6258 - ``--with-universal-archs=all``: install 4-way universal
6259
6260 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6261
6262 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6263
6264 This option should be used in combination with ``--enable-universalsdk=``.
6265
6266 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

6271
Georg Brandl74a1dea2008-05-28 11:21:39 +00006272- Add ``PyType_Modified()`` as a public API to clear the type cache.
6273
6274- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00006275
6276- The PyString functions have been renamed to PyBytes. A batch of
6277 defines were added so that the linker still sees the original
6278 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006316- Issue #1631171: Re-implement the 'warnings' module in C (the
6317 original Python code has been kept as backup). This will allow for
6318 using the 'warning's machinery in such places as the parser where
6319 use of pure Python code is not possible. Both the ``showarning()``
6320 and ``formatwarning()`` gain an optional 'line' argument which is
6321 not called by default for backwards-compatibility reasons. Setting
6322 ``warnings.showwarning()`` to an implementation that lacks support
6323 for the ``line`` argument will raise a DeprecationWarning.

6347
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00006348- The getpass module has been improved on Unix. It now uses /dev/tty
6349 by default and uses stderr instead of stdout. A GetPassWarning is
6350 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00006351

6363 removed and replaced by pure python code.
Amaury Forgeot d'Arc02f33b42008-04-08 23:10:07 +00006364
Georg Brandl3ee81df2008-05-17 18:14:43 +00006365- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00006366 extension modules between 32 and 64 bit platforms. See the distutls

6379 so the controlled environment will more closely mirror the typical
6380 script environment. This supports setup.py scripts that refer to
6381 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006386- Issue #2550: The approach used by client/server code for obtaining
6387 ports to listen on in network-oriented tests has been refined in an
6388 effort to facilitate running multiple instances of the entire
6389 regression test suite in parallel without issue.
6390 test_support.bind_port() has been fixed such that it will always
6391 return a unique port -- which wasn't always the case with the
6392 previous implementation, especially if socket options had been set
6393 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6394 new implementation of bind_port() will actually raise an exception
6395 if it is passed an AF_INET/SOCK_STREAM socket with either the
6396 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6397 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6398 the socket it's been passed. This currently only applies to
6399 Windows. This option prevents any other sockets from binding to the
6400 host/port we've bound to, thus removing the possibility of the
6401 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6402 when a second SOCK_STREAM socket binds and accepts to a host/port
6403 that's already been bound by another socket. The optional preferred
6404 port parameter to bind_port() has been removed. Under no
6405 circumstances should tests be hard coding ports!
6406
6407 test_support.find_unused_port() has also been introduced, which will
6408 pass a temporary socket object to bind_port() in order to obtain an
6409 unused port. The temporary socket object is then closed and
6410 deleted, and the port is returned. This method should only be used
6411 for obtaining an unused port in order to pass to an external program
6412 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6413 a parameter to a server-oriented class that doesn't give you direct
6414 access to the underlying socket used.
6415
6416 Finally, test_support.HOST has been introduced, which should be used
6417 for the host argument of any relevant socket calls (i.e. bind and
6418 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006419
6420 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006421 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006422 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6423 test_asynchat and test_socket_ssl.
6424
Georg Brandl3ee81df2008-05-17 18:14:43 +00006425 It is now possible for multiple instances of the regression test
6426 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006705- Added the future_builtins module, which contains hex() and oct().
6706 These are the PEP 3127 version of these functions, designed to be
6707 compatible with the hex() and oct() builtins from Python 3.0. They
6708 differ slightly in their output formats from the existing, unchanged
6709 Python 2.6 builtins. The expected usage of the future_builtins
6710 module is:
6711 from future_builtins import hex, oct
6712
Eric Smith7ef40bf2008-02-20 23:34:22 +00006713- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6714 exponents for exponents with absolute value < 100. Follows C99
6715 standard. This is a change on Windows, which would use 3 digits.
6716 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6717 so that any alterations it does to the resulting string will be
6718 available in stringlib/formatter.h (for float.__format__).
6719
Eric Smith5a3c1352008-02-19 13:21:56 +00006720- Implemented PEP 3101, Advanced String Formatting. This adds a new
6721 builtin format(); a format() method for str and unicode; a
6722 __format__() method to object, str, unicode, int, long, float, and
6723 datetime; the class string.Formatter; and the C API
6724 PyObject_Format().
6725
Georg Brandl3ee81df2008-05-17 18:14:43 +00006726- Fixed several potential crashes, all caused by specially crafted
6727 __del__ methods exploiting objects in temporarily inconsistent
6728 state.

6738 in order to allow pymalloc to free more arenas. Python may give back
6739 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006740
Georg Brandl3ee81df2008-05-17 18:14:43 +00006741- Issue #2045: Fix an infinite recursion triggered when printing a
6742 subclass of collections.defaultdict, if its default_factory is set
6743 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006744
Christian Heimesf75dbef2008-02-08 00:11:31 +00006745- Fixed a minor memory leak in dictobject.c. The content of the free
6746 list was not freed on interpreter shutdown.
6747
Georg Brandl21e99f42010-03-07 15:23:59 +00006748- Limit free list of method and built-in function objects to 256

6752 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006753 to compact the internal free lists of pre-allocted ints and floats.
6754
Georg Brandl3ee81df2008-05-17 18:14:43 +00006755- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6756 calls. Python expected the return type int but the fork familie
6757 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006765- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
6766 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00006767
Georg Brandl3ee81df2008-05-17 18:14:43 +00006768- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6769 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006770
Georg Brandl3ee81df2008-05-17 18:14:43 +00006771- Patch #1473257: generator objects gain a gi_code attribute. This is
6772 the same object as the func_code attribute of the function that
6773 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006774
Georg Brandl3ee81df2008-05-17 18:14:43 +00006775- Issue #1920: "while 0" statements were completely removed by the
6776 compiler, even in the presence of an "else" clause, which is
6777 supposed to be run when the condition is false. Now the compiler
6778 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006779
Guido van Rossumeead05f2008-01-24 18:21:02 +00006780- A few crashers fixed: weakref_in_del.py (issue #1377858);
6781 loosing_dict_ref.py (issue #1303614, test67.py);
6782 borrowed_ref_[34].py (not in tracker).
6783
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006784- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006785 suppressed while an extension is loaded by calling SetErrorMode in
6786 dynload_win.c. The error is still reported properly.
6787
Georg Brandl3ee81df2008-05-17 18:14:43 +00006788- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006789 several extension methods and modules do not work without unicode
6790 support.
6791
Georg Brandl26543b12008-01-21 18:36:51 +00006792- Issue #1882: when compiling code from a string, encoding cookies in the
6793 second line of code were not always recognized correctly.
6794
Georg Brandl14404b62008-01-19 19:27:05 +00006795- Issue #1679: "0x" was taken as a valid integer literal.
6796
Georg Brandl6caad7d2008-01-26 14:19:22 +00006797- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006798 added.
6799
Christian Heimesc94e2b52008-01-14 04:13:37 +00006800- sys.float_info / PyFloat_GetInfo: The floating point information
6801 object was converted from a dict to a specialized structseq object.
6802
Georg Brandl3ee81df2008-05-17 18:14:43 +00006803- Patch #1816: Added sys.flags structseq. It exposes the status of
6804 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006805
Georg Brandl3ee81df2008-05-17 18:14:43 +00006806- Objects/structseq.c: Implemented new structseq representation. The
6807 patch makes structseqs (e.g. the return value of os.stat) more
6808 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006809
Georg Brandl3ee81df2008-05-17 18:14:43 +00006810- Patch #1700288: added a type attribute cache that caches method
6811 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006812
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006813- Bug #1776: __import__() no longer accepts filenames on any platform.
6814 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006815
Georg Brandlaed6c662008-01-07 17:25:53 +00006816- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6817
Georg Brandl3ee81df2008-05-17 18:14:43 +00006818- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6819 envvar and sys.dont_write_bytecode attribute. All these can be set
6820 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006821
Georg Brandl3ee81df2008-05-17 18:14:43 +00006822- Improve some exception messages when Windows fails to load an
6823 extension module. Now we get for example '%1 is not a valid Win32
6824 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006825
Georg Brandl3ee81df2008-05-17 18:14:43 +00006826- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006828- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
6829 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006830
Christian Heimes0a8143f2007-12-18 23:22:54 +00006831- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006832 and INF. float("nan"), float("inf") and float("-inf") now work on
6833 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006834
Georg Brandl3ee81df2008-05-17 18:14:43 +00006835- Compiler now generates simpler and faster code for dictionary
6836 literals. The oparg for BUILD_MAP now indicates an estimated
6837 dictionary size. There is a new opcode, STORE_MAP, for adding
6838 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00006839
Georg Brandl3ee81df2008-05-17 18:14:43 +00006840- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006845- Issue #1538: Avoid copying string in split/rsplit if the split char
6846 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00006847
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00006848- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00006849 SystemError.
6850
Nick Coghlanef01d822007-12-03 12:55:17 +00006851- PEP 366: Allow explicit relative imports when executing modules
6852 inside packages with the -m switch via a new module level
6853 __package__ attribute.
6854

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00006862 attribute of an empty cell object.
6863
Georg Brandl3ee81df2008-05-17 18:14:43 +00006864- Issue #1460: The utf-7 incremental decoder did not accept truncated
6865 input. It now correctly saves its state between chunks of data.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006867- Patch #1739468: Directories and zipfiles containing a __main__.py
6868 file can now be directly executed by passing their name to the
6869 interpreter. The directory/zipfile is automatically inserted as the
6870 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006871
Georg Brandl3ee81df2008-05-17 18:14:43 +00006872- Issue #1265: Fix a problem with sys.settrace, if the tracing
6873 function uses a generator expression when at the same time the
6874 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006875
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006876- sets and frozensets now have an isdisjoint() method.
6877
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006878- optimize the performance of builtin.sum().
6879
Neal Norwitz44f326e2007-10-05 05:29:17 +00006880- Fix warnings found by the new version of the Coverity checker.
6881
Georg Brandl21e99f42010-03-07 15:23:59 +00006882- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006883 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6884 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006885
Georg Brandl3ee81df2008-05-17 18:14:43 +00006886- Issue #1686386: Tuple's tp_repr did not take into account the
6887 possibility of having a self-referential tuple, which is possible
6888 from C code. Nor did object's tp_str consider that a type's tp_str
6889 could do something that could lead to an inifinite recursion.
6890 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6891 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006892
Georg Brandl3ee81df2008-05-17 18:14:43 +00006893- Issue #1164: It was possible to trigger deadlock when using the
6894 'print' statement to write to a file since the GIL was not released
6895 as needed. Now PyObject_Print() does the right thing along with
6896 various tp_print implementations of the built-in types and those in
6897 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006898
Georg Brandl3ee81df2008-05-17 18:14:43 +00006899- Issue #1147: Exceptions were directly allowing string exceptions in
6900 their throw() method even though string exceptions no longer
6901 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006902
Georg Brandl3ee81df2008-05-17 18:14:43 +00006903- Issue #1096: Prevent a segfault from getting the repr of a very
6904 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006905
Brett Cannon1e534b52007-09-07 04:18:30 +00006906- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006907 PyObject_Call() never calling back out to Python code to trigger
6908 recursion depth updates/checks. Required the creation of a static
6909 RuntimeError instance in case normalizing an exception put the
6910 recursion check value past its limit. Fixes crashers
6911 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006912
Georg Brandl3ee81df2008-05-17 18:14:43 +00006913- Patch #1031213: Decode source line in SyntaxErrors back to its

6917 with %G.
6918
Georg Brandl3ee81df2008-05-17 18:14:43 +00006919- Prevent expandtabs() on string and unicode objects from causing a
6920 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00006921

Neal Norwitz0ac60192007-05-27 04:08:54 +00006926- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006927 __*__ attributes. (Some already existed, e.g., __doc__ and
6928 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006929
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006930- Add -3 option to the interpreter to warn about features that are
6931 deprecated and will be changed/removed in Python 3.0.
6932
Georg Brandl2134e752007-05-21 20:34:16 +00006933- Patch #1686487: you can now pass any mapping after '**' in function
6934 calls.
6935
Collin Winter62903052007-05-18 23:11:24 +00006936- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006937 "except E as target:". This is to provide forwards compatibility
6938 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006939
Brett Cannon229cee22007-05-05 01:34:02 +00006940- Deprecate BaseException.message as per PEP 352.
6941
Georg Brandl3ee81df2008-05-17 18:14:43 +00006942- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006943 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006944
Vinay Sajip8549ce32007-05-06 17:53:37 +00006945- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006946 setting a plain string, ie don't expand to single letter identifiers.
6947
Raymond Hettinger13936692007-04-11 18:40:58 +00006948- Request #1191699: Slices can now be pickled.
6949
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006950- Request #1193128: str.translate() now allows a None argument for
6951 translations that only remove characters without re-mapping the
6952 remaining characters.
6953
Georg Brandl5cb76c12007-03-21 09:00:39 +00006954- Patch #1682205: a TypeError while unpacking an iterable is no longer
6955 masked by a generic one with the message "unpack non-sequence".
6956
Neal Norwitzaa754b72007-03-21 06:39:48 +00006957- Remove unused file Python/fmod.c.
6958
Guido van Rossum143b5642007-03-23 04:58:42 +00006959- Bug #1683368: The object.__init__() and object.__new__() methods are
6960 now stricter in rejecting excess arguments. The only time when
6961 either allows excess arguments is when it is not overridden and the
6962 other one is. For backwards compatibility, when both are
6963 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006964 warning later). Also, type.__init__() insists on the same signature
6965 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006966
Georg Brandl3ee81df2008-05-17 18:14:43 +00006967- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6968 object to complex using its __complex__() method before falling back
6969 to the __float__() method. Therefore, the functions in the cmath
6970 module now can operate on objects that define a __complex__()
6971 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006972
Georg Brandl3ee81df2008-05-17 18:14:43 +00006973- Patch #1623563: allow __class__ assignment for classes with
6974 __slots__. The old and the new class are still required to have the
6975 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006976
Georg Brandl3ee81df2008-05-17 18:14:43 +00006977- Patch #1642547: Fix an error/crash when encountering syntax errors

6981 ``object.__reduce_ex__()`` is called with an object that is faking
6982 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00006983
Georg Brandl3ee81df2008-05-17 18:14:43 +00006984- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00006987- Patch #1444529: the builtin compile() now accepts keyword arguments.
6988
Georg Brandl7b9c5552007-03-12 14:30:05 +00006989- Bug #1678647: write a newline after printing an exception in any
6990 case, even when converting the value to a string failed.
6991
Georg Brandl871f1bc2007-03-12 13:17:36 +00006992- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006993 its argument, if it exists. If not, it will work like before. This
6994 allows customizing the output of dir() in the presence of a
6995 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00006996
Collin Winter276887b2007-03-12 16:11:39 +00006997- Patch #922167: Python no longer segfaults when faced with infinitely
6998 self-recursive reload() calls (as reported by bug #742342).
6999
Georg Brandl3ee81df2008-05-17 18:14:43 +00007000- Patch #1675981: remove unreachable code from ``type.__new__()``
7001 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00007002
Georg Brandl3ee81df2008-05-17 18:14:43 +00007003- Patch #1491866: change the complex() constructor to allow

7516 ".cpp" too.
7517
Facundo Batistad918a652007-04-24 13:54:38 +00007518- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007519 the client's request was successfully received, understood, and
7520 accepted. Now in these cases no error is raised in urllib (issue
7521 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00007522

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00007529- Added a timeout parameter to the constructor of other protocols
7530 (telnetlib, ftplib, smtplib and poplib). This is second part of the
7531 work started with create_connection() and timeout in httplib, and
7532 closes patch #723312.
7533
Vinay Sajip8549ce32007-05-06 17:53:37 +00007534- Patch #1676823: Added create_connection() to socket.py, which may be
7535 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00007536 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00007537
Martin v. Löwis0af33882007-03-23 13:27:15 +00007538- Bug #978833: Revert r50844, as it broke _socketobject.dup.

7558
Georg Brandlf66b6032007-03-14 08:27:52 +00007559- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00007560 AttributeError instead of an IOError when the server's response
7561 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00007562
Georg Brandl3ee81df2008-05-17 18:14:43 +00007563- Patch #957650: "%var%" environment variable references are now
7564 properly expanded in ntpath.expandvars(), also "~user" home
7565 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00007566
Georg Brandl3ee81df2008-05-17 18:14:43 +00007567- Patch #1429539: pdb now correctly initializes the __main__ module
7568 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00007569 correctly now.
7570
Georg Brandlbad6f192007-03-13 21:32:56 +00007571- The nonobvious commands.getstatus() function is now deprecated.

7577
Georg Brandl3ee81df2008-05-17 18:14:43 +00007578- Patch #1530482: add pydoc.render_doc() which returns the
7579 documentation for a thing instead of paging it to stdout, which
7580 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00007581
Georg Brandl3ee81df2008-05-17 18:14:43 +00007582- Patch #1533909: the timeit module now accepts callables in addition

7588 parameter which can be set to False to prevent the default
7589 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00007591- Patch #1581073: add a flag to textwrap that prevents the dropping of
7592 whitespace while wrapping.
7593
Georg Brandl92a6bae2007-03-13 17:43:32 +00007594- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007595 are set for invalid interpolation sequences that would lead to
7596 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00007597

7610
Georg Brandl94fe3f52007-03-13 09:32:11 +00007611- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00007612 field names in its exception message if you try to write a record
7613 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00007631

7639 returned string up to the first NUL character.
7640

7650
Georg Brandl3ee81df2008-05-17 18:14:43 +00007651- unittest now verifies more of its assumptions. In particular,
7652 TestCase and TestSuite subclasses (not instances) are no longer
7653 accepted in TestSuite.addTest(). This should cause no
7654 incompatibility since it never made sense with ordinary subclasses
7655 -- the failure just occurred later, with a more cumbersome
7656 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00007657

7665 given a unicode argument and os.listdir() returns unicode filenames.
7666
Georg Brandl3ee81df2008-05-17 18:14:43 +00007667- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00008045 time so that opening a database previously created with the DB_DUP
8046 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8047 opens. Specifically: dictionary assignment to a DB object will
8048 replace all values for a given key when the database allows
8049 duplicate values. DB users should use DB.put(k, v) when they want
8050 to store duplicates; not DB[k] = v.

8057 characters with ASCII value less than 32. Also, it correctly quotes
8058 dots only if they occur on a single line, as opposed to the previous
8059 behavior of quoting dots if they are the second character of any
8060 line.
