136 int.__pow__. These overflow checks were causing int.__pow__ to produce
137 incorrect results with recent versions of Clang, as a result of the

139 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Antoine Pitrou16166452011-07-12 22:04:20 +0200151- Issue #12149: Update the method cache after a type's dictionnary gets
152 cleared by the garbage collector. This fixes a segfault when an instance
153 and its type get caught in a reference cycle, and the instance's
154 deallocator calls one of the methods on the type (e.g. when subclassing
155 IOBase). Diagnosis and patch by Davide Rizzo.

Florent Xiclunac2279652012-02-12 14:49:03 +0100208- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100209 has left two versions of customize_compiler, the original in
210 distutils.sysconfig and another copy in distutils.ccompiler, with some

213 is the case in 3.x.
214
Ned Deily0d0ea482012-02-10 12:59:06 +0100215- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
216 Distutils-based packages with C extension modules may fail because
217 Apple has removed gcc-4.2, the version used to build python.org
218 64-bit/32-bit Pythons. If the user does not explicitly override
219 the default C compiler by setting the CC environment variable,
220 Distutils will now attempt to compile extension modules with clang
221 if gcc-4.2 is required but not found. Also as a convenience, if
222 the user does explicitly set CC, substitute its value as the default
223 compiler in the Distutils LDSHARED configuration variable for OS X.
224 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
225 SDK, neither of which are available in Xcode 4. This change does not
226 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700499- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
500 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
501 interpreter process. This could cause failures in non-Distutils subprocesses
502 and was unreliable since tests or user programs could modify the interpreter
503 environment after Distutils set it. Instead, have Distutils set the the
504 deployment target only in the environment of each build subprocess. It is
505 still possible to globally override the default by setting
506 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
507 greater or equal to the default value, the value with which the interpreter
508 was built.

537 updating the check interval, so if the user decreases the check interval,
538 the ticker doesn't have to wind down to zero from the old starting point
539 before the new interval takes effect. And if the user increases the
540 interval, it makes sure the new limit takes effect right away rather have an
541 early task switch before recognizing the new interval.

1475 by Andrew Bennetts.

1484
Raymond Hettinger20397532010-09-12 02:11:45 +00001485- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1486 This prevents user-created self-referencing ordered dictionaries from
1487 becoming permanently uncollectable GC garbage. The downside is that
1488 removing __del__ means that the internal doubly-linked list has to wait for
1489 GC collection rather than freeing memory immediately when the refcnt drops
1490 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001949- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the

1952 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1953 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

1965 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

2332Core and Builtins
2333-----------------
2334
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002335- Issue #7301: Add environment variable $PYTHONWARNINGS.
2336
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002337- Issue #8329: Don't return the same lists from select.select when no fds are
2338 changed.
2339
Georg Brandlfee0f442010-05-22 21:26:21 +00002340- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002341 on 64-bit machines. The shift count for either left or right shift is
2342 permitted to be up to sys.maxsize.
2343
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002344- Ensure that tokenization of identifiers is not affected by locale.
2345
Georg Brandlfee0f442010-05-22 21:26:21 +00002346- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002347
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002348- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2349
Georg Brandlfee0f442010-05-22 21:26:21 +00002350- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2351 with a non-empty format string. This is an effort to future-proof user
2352 code. If a derived class does not currently implement __format__ but later
2353 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002354 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002355 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002356
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002357- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00002370- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002371 (SIGINT). If an error occurs while importing the site module, the error is
2372 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00002373 module.

2387
Georg Brandlfee0f442010-05-22 21:26:21 +00002388- Issue #8257: The Decimal construct now accepts a float instance directly,
2389 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002390
2391 >>> Decimal(1.1)
2392 Decimal('1.100000000000000088817841970012523233890533447265625')
2393
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002394- collections.Counter() now supports a subtract() method.
2395
Georg Brandlfee0f442010-05-22 21:26:21 +00002396- The functools module now has a total_ordering() class decorator to simplify
2397 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002398
Georg Brandlfee0f442010-05-22 21:26:21 +00002399- The functools module also adds cmp_to_key() as a tool to transition old-style
2400 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002401
Georg Brandlfee0f442010-05-22 21:26:21 +00002402- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2403 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002404
Georg Brandlfee0f442010-05-22 21:26:21 +00002405- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2406 InvalidOperation instead of returning False. (Comparisons involving a quiet
2407 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2408 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002409
Georg Brandlfee0f442010-05-22 21:26:21 +00002410- Issue #2531: Comparison operations between floats and Decimal instances now
2411 return a result based on the numeric values of the operands; previously they
2412 returned an arbitrary result based on the relative ordering of id(float) and
2413 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002414
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002415- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002416 argument `-` which tells it to read files to compile from stdin. Each line is
2417 read on demand and the named file is compiled immediately. (Original patch by
2418 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002419
Georg Brandlfee0f442010-05-22 21:26:21 +00002420- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00002423- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2424 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002425 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002426
Georg Brandlfee0f442010-05-22 21:26:21 +00002427- Comparisons using one of <, <=, >, >= between a complex instance and a
2428 Fractions instance now raise TypeError instead of returning True/False. This
2429 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2430 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00002431

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002441- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00002442 didn't support chflags() (for example ZFS under FreeBSD). The error is now
2443 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002444
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00002445- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

Georg Brandlfee0f442010-05-22 21:26:21 +00002486 for ``TimedRotatingFileHandler`` by using the modification time of an existing
2487 log file to compute the next rollover time. If the log file does not exist,
2488 the current time is used as the basis for the computation.

2535 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2536 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002537 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2538 inconsistent: __int__ was used for some integer codes but not for others, and
2539 the set of integer codes for which it was used differed between native packing
2540 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00002749- Issue #6292: For the moment at least, the test suite runs cleanly if python
R. David Murrayf28fd242010-02-23 00:24:49 +00002750 is run with the -OO flag. Tests requiring docstrings are skipped.
2751
Georg Brandlba83f822010-03-14 09:50:54 +00002752- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
2753 now also used by regrtest to run all the tests in a temporary directory. The
2754 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
2755 Xicluna who helped with the patch.

Antoine Pitroubb445a12010-02-05 17:05:54 +00002771- Issue #5677: Explicitly forbid write operations on read-only file objects,
2772 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00002773 library would return a bogus result; on Solaris, it was possible to crash the
2774 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +00002787- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
2788 and add the additional members returned in an OSVERSIONINFOEX structure. The
2789 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00002792- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2793 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2794 returning NULL. The macro now returns a statically allocated empty string
2795 instead.

2805 strings,
2806 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2807 numeric strings corresponding to subnormal values,
2808 (3) a memory leak for some values large enough to cause overflow, and
2809 (4) a number of flaws that could lead to incorrectly rounded results.

2827 interpreter shutdown.
2828
Georg Brandlba83f822010-03-14 09:50:54 +00002829- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in

2831 by the XML specification, and are necessary when outputting e.g. PHP code in
2832 a processing instruction. Patch by Neil Muller.

Antoine Pitroud840e512010-02-04 20:20:18 +00002840- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002841 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00002842 Also, raise ValueError rather than TypeError when an unknown TIPC address
2843 type is specified. Patch by Brian Curtin.
2844
Vinay Sajip28c382f2010-02-04 18:48:53 +00002845- logging: Implemented PEP 391.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002847- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002848 file position when calling `truncate()`. It would previously change the file
2849 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002850 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2851
Georg Brandlba83f822010-03-14 09:50:54 +00002852- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2853 class used to represent files stored inside an archive. The new
2854 implementation is significantly faster and can be wrapped in a
2855 ``io.BufferedReader`` object for more speedups. It also solves an issue
2856 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
2857 Patch by Nir Aides.
Antoine Pitrou94c33eb2010-01-27 20:59:50 +00002858
Benjamin Peterson2deb5c72010-01-27 02:16:42 +00002859- Issue #7792: Registering non-classes to ABCs raised an obscure error.
2860
Georg Brandlba83f822010-03-14 09:50:54 +00002861- Removed the deprecated functions ``verify()`` and ``vereq()`` from

2865 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +00002866
Georg Brandlba83f822010-03-14 09:50:54 +00002867- Issue #7748: Since unicode values are supported for some metadata options in
2868 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2869 encoded string for them. This ensures that the upload and register commands
2870 send the correct values to PyPI without any error.

2946
Georg Brandlba83f822010-03-14 09:50:54 +00002947- The ``__complex__()`` method is now looked up on the class of instances to
2948 make it consistent with other special methods.

2952
Mark Dickinson1b34d252010-01-01 17:27:30 +00002953- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002954 DeprecationWarning when passed a float argument where an integer was expected.
2955 These functions and methods now raise TypeError instead. The majority of the
2956 effects of this change are in the extension modules, but some core functions
2957 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2958 and many unicode/str methods.

2972 of integers: the result of a/b is now correctly rounded for ints a and b (at
2973 least on IEEE 754 platforms), and in particular does not depend on the
2974 internal representation of a long.

2982
Georg Brandlba83f822010-03-14 09:50:54 +00002983 These executables now work properly with the arch(1) command: ``arch -ppc
2984 python`` will start a universal binary version of python in PPC mode (unlike

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003140
Georg Brandlba83f822010-03-14 09:50:54 +00003141- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3142 decimal string that's guaranteed to round back to x under correct rounding
3143 (with round-half-to-even rounding mode). Previously it gave a string based on
3144 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3145 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3146 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003147
Georg Brandlba83f822010-03-14 09:50:54 +00003148- Issue #7117: On almost all platforms: float-to-string and string-to-float
3149 conversions within Python are now correctly rounded. Places these conversions
3150 occur include: str for floats and complex numbers; the float and complex
3151 constructors; old-style and new-style numeric formatting; serialization and
3152 deserialization of floats and complex numbers using marshal, pickle and json;
3153 parsing of float and imaginary literals in Python code; Decimal-to-float
3154 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003155
Georg Brandlba83f822010-03-14 09:50:54 +00003156 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3157 providing correctly-rounded strtod and dtoa C functions. This code is
3158 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3159 the C compiler. There may be a small number of platforms on which correct
3160 operation of this code cannot be guaranteed, so the code is not used: notably,
3161 this applies to platforms where the C double format is not IEEE 754 binary64,
3162 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3163 and Python's configure script is unable to determine how to change the FPU
3164 precision. On these platforms conversions use the platform strtod and dtoa,
3165 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003166
Georg Brandlba83f822010-03-14 09:50:54 +00003167- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3168 uses the correctly-rounded string <-> float conversions described above (when
3169 available), and so produces correctly rounded results that will display nicely
3170 under the float repr. There are two related small changes: (1) round now
3171 accepts any class with an ``__index__()`` method for its second argument (but
3172 no longer accepts floats for the second argument), and (2) an excessively
3173 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3174 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003321- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3322 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3323 but with at least one decimal point and with a default precision
3324 of 12. Previously, the behavior the same but with a default precision of 6.
3325 This more closely matches ``str()``, and reduces surprises when adding
3326 alignment flags to the empty presentation type. This also affects the new
3327 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00003467- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
3468 existing .py counterpart, override the co_filename attributes of all code

3524
Georg Brandlba83f822010-03-14 09:50:54 +00003525- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3526 file objects with closefd=False. The file descriptor is still kept open but
3527 the file object behaves like a closed file. The ``FileIO`` object also got a
3528 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00003551- On windows, ``os.chdir()`` given unicode was not working if
3552 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3553 this code path is really executed because I cannot move to such directory on
3554 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00003556- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3557 element is temporarily replaced with an equivalent frozenset. But the
3558 eventual KeyError would always report the empty ``frozenset()`` as the missing
3559 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00003579- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3580 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3581 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3582 of using the replace error handler in PyUnicode_DecodeUTF8().
3583
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003584- Issue #3739: The unicode-internal encoder now reports the number of characters

3586
Georg Brandlba83f822010-03-14 09:50:54 +00003587- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

3589 gives improved memory leak detection when running under Valgrind, while taking
3590 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00004813 leak-chasing test runs give sensible results. The previous method of reaping
4814 threads could return successfully while some Thread objects were still
4815 referenced. This also introduces a new private function: ``thread._count()``.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00004832- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
4833 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00004834 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
4835 the tests if DISPLAY is defined but can't be used.

4841 import both normal and optimised versions of modules. test_heapq and
4842 test_warnings have been adjusted to use it, tests for other modules with both
4843 C and Python implementations in the stdlib can be adjusted to use it over
4844 time.

4853 should cause a test to be skipped are now done using import_module from test
4854 support, which does the conversion.

4956
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004957- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4958 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4959 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4960 ``printf`` function, whereas PyString_FromFormat has an independent
4961 implementation and uses "%zd" on all platforms for size_t values.
4962 This makes a difference on win64, where ``printf`` needs "%Id" to display
4963 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00004965- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

4969 object; previously an int would be returned for small values. the __long__
4970 method is allowed to return either an int or a long, but the behaviour of
4971 float objects should not change to respect backward compatibility.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004980 was correctly parsed but parsing of subsequent arguments failed.
4981
Vinay Sajip35e3b032008-09-01 14:33:59 +00004982- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004983 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4984 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4985 when given a tuple of classes as second argument, were looking up
4986 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4987 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005126What's New in Python 2.6 beta 3?
5127================================
5128
Barry Warsaw07a4a382008-08-21 01:15:08 +00005129*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005130
5131Core and Builtins
5132-----------------
5133
Guido van Rossumf8402962008-08-20 15:01:50 +00005134- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5135 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5136 extensions do not automatically benefit from the class attribute
5137 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5138 to their tp_flags field if they care. This is a backwards
5139 compatibility feature; in 3.0, all types will use the cache by
5140 default.
5141
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005142- Keyword arguments can now follow starred arguments. (``f(a, *args,
5143 keyword=23)`` is now valid syntax.)
5144
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005145- ctypes function pointers that are COM methods have a boolean True
5146 value again.
5147
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005148- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5149 by denying s# to parse objects that have a releasebuffer procedure,
5150 and introducing s*.
5151
Georg Brandl1e13ea92008-08-11 09:07:59 +00005152- Issue #3537: Fix an assertion failure when an empty but presized dict
5153 object was stored in the freelist.
5154
Mark Dickinsonb6467572008-08-04 21:30:09 +00005155- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5156 ValueError consistently across platforms.
5157
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005158- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5159 (64bit Unix, for example), unichr() would truncate its argument and return
5160 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5161
Neal Norwitze7d8be82008-07-31 17:17:14 +00005162- Apply security patches from Apple.
5163
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005164- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5165 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5166
Antoine Pitrou92f82162008-07-25 22:22:08 +00005167- Issue #1819: function calls with several named parameters are now on
5168 average 35% faster (as measured by pybench).
5169
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005170- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5171 the python debugger steps into a class statement: the free variables (local
5172 variables defined in an outer scope) would be deleted from the outer scope.
5173
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005174- Issue #2620: Overflow checking when allocating or reallocating memory
5175 was not always being done properly in some python types and extension
5176 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5177 all been updated to perform better checks and places in the code that
5178 would previously leak memory on the error path when such an allocation
5179 failed have been fixed.

5182-------
5183
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005184- Issue #3612: Added some missing basic types in ctypes.wintypes.
5185
Benjamin Petersone977ad42008-08-20 01:42:01 +00005186- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5187 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5188
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005189- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5190 version reported by these tools does not necessarily follow the python
5191 version numbering scheme, so the module is less strict when parsing it.
5192
Nick Coghlanf70385a2008-08-18 12:42:46 +00005193- Issue #2235: Added Py3k warnings for types which will become unhashable
5194 under the stricter __hash__ inheritance rules in 3.0. Several types
5195 which did not meet the rules for hash invariants and were already
5196 unhashable in 3.0 have now been explicitly flagged as unhashable in
5197 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5198 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5199
Brett Cannon88f801d2008-08-18 00:46:22 +00005200- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5201 imported into the module but exposed as part of the module's API.
5202
Brett Cannon7b96f072008-08-18 00:41:11 +00005203- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5204
Brett Cannon46225e72008-08-18 00:36:52 +00005205- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
5206
Brett Cannon25c9d6a2008-08-17 22:10:11 +00005207- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5208
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005209- Issue #3575: Incremental decoder's decode function now takes bytearray
5210 by using 's*' instead of 't#'.
5211
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005212- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005213 fails unicode conversion on 2nd parameter. (windows only)
5214
Georg Brandl222e2082010-08-01 22:27:39 +00005215- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005216 in a redirect.
5217
Brett Cannonabe423e2008-08-16 21:47:07 +00005218- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005219 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005220
Facundo Batistaeb90b782008-08-16 14:44:07 +00005221- Issue #2776: fixed small issue when handling an URL with double slash
5222 after a 302 response in the case of not going through a proxy.
5223
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005224- Issue #2676: in the email package, content-type parsing was hanging on
5225 pathological input because of quadratic or exponential behaviour of a
5226 regular expression.
5227
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005228- Issue #3476: binary buffered reading through the new "io" library is now
5229 thread-safe.
5230
Brett Cannonbf3157b2008-08-14 05:00:03 +00005231- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5232 since mimetools itself is deprecated. Because modules are cached, all
5233 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5234
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005235- Issue #3134: shutil referenced undefined WindowsError symbol.
5236
Robert Schuppenies14646332008-08-10 11:01:53 +00005237- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5238 menu entries were not deleted.
5239
Brett Cannon83e81842008-08-09 23:30:55 +00005240- Copied the implementation of reduce() to _functools.reduce() to have a
5241 version that did not raise a DeprecationWarning under -3.
5242
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005243- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5244 a MemoryError rather than silently stop the iteration.
5245
Guido van Rossum59ce9012008-08-09 14:55:34 +00005246- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5247 to _sre.compile() will now be rejected. This should not affect anybody
5248 since the re.compile() function never generates invalid re-bytecode.
5249
Skip Montanaroa032bf42008-08-08 22:52:51 +00005250- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5251 upon first access it can be automatically initialized from the csv file if
5252 it wasn't initialized during instantiation.
5253
Brett Cannon3aa2a492008-08-06 22:28:09 +00005254- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5255 the reload() built-in has been removed.
5256
Brett Cannon7e30b672008-08-04 21:52:25 +00005257- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005258 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

5261 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
5262 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
5263 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00005264
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00005265- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
5266 raised an AttributeError.
5267
Benjamin Peterson01a24322008-07-28 23:35:27 +00005268- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00005269 asking for a specific length. This problem only affected files opened
5270 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005271
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00005272- Issue #3449: Update decimal module to use most recent specification
5273 (v. 1.68) and tests (v. 2.58) from IBM.
5274
Georg Brandl222e2082010-08-01 22:27:39 +00005275- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00005276
Georg Brandl222e2082010-08-01 22:27:39 +00005277- Issue #1592: Improve error reporting when operations are attempted
Raymond Hettinger8c664e82008-07-25 18:43:33 +00005278 on a closed shelf.
5279
Georg Brandlf9efabb2008-07-23 15:16:45 +00005280- Deprecate the "ast" parser function aliases.
5281
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005282- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
5283
5284- Issue #3303: Fix a crash in locale.strcoll() when calling it with
5285 invalid arguments.
5286
5287- Issue #3302: Fix several crashes when calling locale's gettext functions
5288 with None arguments.
5289
5290- Issue #3389: Allow resolving dotted names for handlers in logging
5291 configuration files.
5292
5293- Deprecate the sunaudio module for removal in Python 3.0.
5294
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005295- Issue #3394: zipfile.writestr sets external attributes when passed a
5296 file name rather than a ZipInfo instance, so files are extracted with
5297 mode 0600 rather than 000 under Unix.
5298
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005299- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5300 argument in python 2.5, this broke code that subclassed Popen to include its
5301 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00005311- Issue #2235: the C API function PyObject_HashNotImplemented and its
5312 interaction with the tp_hash slot (added in 2.6b2) are now documented
5313
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005314- Issue #643841: The language reference now provides more detailed
5315 coverage of the lookup process for special methods. The disclaimers
5316 regarding lack of coverage of new-style classes have also been
5317 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005320What's New in Python 2.6 beta 2?
5321================================
5322
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005323*Release date: 17-Jul-2008*
5324
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005325Core and Builtins
5326-----------------
5327
Georg Brandl3e483f62008-07-16 22:57:41 +00005328- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5329 its methods now allow for items objects that can be converted to
5330 an integer using operator.index().
5331
Mark Dickinson64b7e502008-07-16 09:40:03 +00005332- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5333 produced a ValueError instead of giving the correct float.
5334
Eric Smitha5fa5a22008-07-16 00:11:49 +00005335- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5336 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5337
Mark Dickinson7103aa42008-07-15 19:08:33 +00005338- Issue #3008: the float type has a new instance method 'float.hex'
5339 and a new class method 'float.fromhex' to convert floating-point
5340 numbers to and from hexadecimal strings, respectively.
5341
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005342- Issue #2235: __hash__ is once again inherited by default. To allow
5343 collections.Hashable to remain meaningful in the presence of the
5344 default hash implementation (object.__hash__), it is now possible
5345 to explicit block inheritance of hash by setting __hash__=None at
5346 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5347 level.
5348
Nick Coghlanb028f502008-07-13 14:52:36 +00005349- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5350 the parent module cannot be found while performing an absolute import.
5351 This means that an incorrectly defined __package__ attribute will
5352 now only prevent relative imports in that module rather than causing
5353 all imports from that module to fail.
5354
Nick Coghlan14ff9942008-07-08 14:21:42 +00005355- Issue #2517: Allow unicode messages in Exceptions again by correctly
5356 bypassing the instance dictionary when looking up __unicode__ on
5357 new-style classes.
5358
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005359- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5360 set to a custom object whose write() method happens to install
5361 another file in sys.stdout.
5362
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005363- Issue #3088: Corrected a race condition in classes derived from
5364 threading.local: the first member set by a thread could be saved in
5365 another thread's dictionary.
5366
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005367- Issue #3004: Minor change to slice.indices(): the start and stop
5368 arguments are now treated identically, making the behaviour easier
5369 to describe and understand. For example, slice(None, -10,
5370 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5371 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5372 10, -1).
5373
Georg Brandl278fc502008-07-19 12:46:12 +00005374- Issue #3219: Calling a function with repeated keyword arguments,
5375 f(a=2, a=23), would not cause a syntax error. This was a regression
5376 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00005378- Issue #2862: Make int and float freelist management consistent with
5379 other freelists. Changes their CompactFreeList apis into
5380 ClearFreeList apis and calls them via gc.collect().

5386 api functions without holding the GIL, which could lead to a fatal
5387 error when they failed.
5388
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005389- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Georg Brandl5cc774e2008-06-11 20:28:06 +00005826 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005827
5828 This is controlled by the configure argument ``--with-universal-archs``:
5829
5830 - ``--with-universal-archs=all``: install 4-way universal
5831
5832 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5833
5834 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5835
5836 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005888- Issue #1631171: Re-implement the 'warnings' module in C (the
5889 original Python code has been kept as backup). This will allow for
5890 using the 'warning's machinery in such places as the parser where
5891 use of pure Python code is not possible. Both the ``showarning()``
5892 and ``formatwarning()`` gain an optional 'line' argument which is
5893 not called by default for backwards-compatibility reasons. Setting
5894 ``warnings.showwarning()`` to an implementation that lacks support
5895 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithaa63d0d2008-04-06 23:11:17 +00005941- Issue #815646: Individual file objects may now be used from multiple
5942 threads at once without fear of crashing the Python interpreter. If
5943 file.close() is called while an object is in use by another thread
5944 an IOError exception will be raised and the file will not be closed.

5948 Modules/_ctypes/libffi/configure.ac.
5949
Georg Brandl3ee81df2008-05-17 18:14:43 +00005950- Issue #2385: distutils.core.run_script() makes __file__ available,
5951 so the controlled environment will more closely mirror the typical
5952 script environment. This supports setup.py scripts that refer to
5953 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005958- Issue #2550: The approach used by client/server code for obtaining
5959 ports to listen on in network-oriented tests has been refined in an
5960 effort to facilitate running multiple instances of the entire
5961 regression test suite in parallel without issue.
5962 test_support.bind_port() has been fixed such that it will always
5963 return a unique port -- which wasn't always the case with the
5964 previous implementation, especially if socket options had been set
5965 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5966 new implementation of bind_port() will actually raise an exception
5967 if it is passed an AF_INET/SOCK_STREAM socket with either the
5968 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5969 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5970 the socket it's been passed. This currently only applies to
5971 Windows. This option prevents any other sockets from binding to the
5972 host/port we've bound to, thus removing the possibility of the
5973 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5974 when a second SOCK_STREAM socket binds and accepts to a host/port
5975 that's already been bound by another socket. The optional preferred
5976 port parameter to bind_port() has been removed. Under no
5977 circumstances should tests be hard coding ports!
5978
5979 test_support.find_unused_port() has also been introduced, which will
5980 pass a temporary socket object to bind_port() in order to obtain an
5981 unused port. The temporary socket object is then closed and
5982 deleted, and the port is returned. This method should only be used
5983 for obtaining an unused port in order to pass to an external program
5984 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5985 a parameter to a server-oriented class that doesn't give you direct
5986 access to the underlying socket used.
5987
5988 Finally, test_support.HOST has been introduced, which should be used
5989 for the host argument of any relevant socket calls (i.e. bind and
5990 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005991
5992 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005993 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005994 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5995 test_asynchat and test_socket_ssl.
5996
Georg Brandl3ee81df2008-05-17 18:14:43 +00005997 It is now possible for multiple instances of the regression test
5998 suite to run in parallel without issue.

Thomas Heller78b8f442008-03-05 14:53:39 +00006202- The bundled libffi copy is now in sync with the recently released
6203 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006204 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
6205 files are used. On all linux systems the --with-system-ffi
6206 configure option defaults to "yes".

Fred Drakea8ee94b2008-03-01 02:45:07 +00006267- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00006268 644. The mode is now inherited from the py file.

Eric Smitha73fbe72008-02-23 03:09:44 +00006277- Added the future_builtins module, which contains hex() and oct().
6278 These are the PEP 3127 version of these functions, designed to be
6279 compatible with the hex() and oct() builtins from Python 3.0. They
6280 differ slightly in their output formats from the existing, unchanged
6281 Python 2.6 builtins. The expected usage of the future_builtins
6282 module is:
6283 from future_builtins import hex, oct
6284
Eric Smith7ef40bf2008-02-20 23:34:22 +00006285- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6286 exponents for exponents with absolute value < 100. Follows C99
6287 standard. This is a change on Windows, which would use 3 digits.
6288 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6289 so that any alterations it does to the resulting string will be
6290 available in stringlib/formatter.h (for float.__format__).
6291
Eric Smith5a3c1352008-02-19 13:21:56 +00006292- Implemented PEP 3101, Advanced String Formatting. This adds a new
6293 builtin format(); a format() method for str and unicode; a
6294 __format__() method to object, str, unicode, int, long, float, and
6295 datetime; the class string.Formatter; and the C API
6296 PyObject_Format().
6297
Georg Brandl3ee81df2008-05-17 18:14:43 +00006298- Fixed several potential crashes, all caused by specially crafted
6299 __del__ methods exploiting objects in temporarily inconsistent
6300 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006301
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006302- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006303 prevent a possible crash: an Abstract Base Class would try to access
6304 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006305

Georg Brandl3ee81df2008-05-17 18:14:43 +00006309- Clear all free lists during a gc.collect() of the highest generation
6310 in order to allow pymalloc to free more arenas. Python may give back
6311 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006312
Georg Brandl3ee81df2008-05-17 18:14:43 +00006313- Issue #2045: Fix an infinite recursion triggered when printing a
6314 subclass of collections.defaultdict, if its default_factory is set
6315 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006316
Christian Heimesf75dbef2008-02-08 00:11:31 +00006317- Fixed a minor memory leak in dictobject.c. The content of the free
6318 list was not freed on interpreter shutdown.
6319
Georg Brandl21e99f42010-03-07 15:23:59 +00006320- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006321 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006322
Georg Brandl3ee81df2008-05-17 18:14:43 +00006323- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6324 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006325 to compact the internal free lists of pre-allocted ints and floats.
6326
Georg Brandl3ee81df2008-05-17 18:14:43 +00006327- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6328 calls. Python expected the return type int but the fork familie
6329 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006330
Georg Brandl3ee81df2008-05-17 18:14:43 +00006331- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00006343- Patch #1473257: generator objects gain a gi_code attribute. This is
6344 the same object as the func_code attribute of the function that
6345 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006346
Georg Brandl3ee81df2008-05-17 18:14:43 +00006347- Issue #1920: "while 0" statements were completely removed by the
6348 compiler, even in the presence of an "else" clause, which is
6349 supposed to be run when the condition is false. Now the compiler
6350 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006351
Guido van Rossumeead05f2008-01-24 18:21:02 +00006352- A few crashers fixed: weakref_in_del.py (issue #1377858);
6353 loosing_dict_ref.py (issue #1303614, test67.py);
6354 borrowed_ref_[34].py (not in tracker).
6355
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006356- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006357 suppressed while an extension is loaded by calling SetErrorMode in
6358 dynload_win.c. The error is still reported properly.
6359
Georg Brandl3ee81df2008-05-17 18:14:43 +00006360- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006361 several extension methods and modules do not work without unicode
6362 support.
6363
Georg Brandl26543b12008-01-21 18:36:51 +00006364- Issue #1882: when compiling code from a string, encoding cookies in the
6365 second line of code were not always recognized correctly.
6366
Georg Brandl14404b62008-01-19 19:27:05 +00006367- Issue #1679: "0x" was taken as a valid integer literal.
6368
Georg Brandl6caad7d2008-01-26 14:19:22 +00006369- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006370 added.
6371
Christian Heimesc94e2b52008-01-14 04:13:37 +00006372- sys.float_info / PyFloat_GetInfo: The floating point information
6373 object was converted from a dict to a specialized structseq object.
6374
Georg Brandl3ee81df2008-05-17 18:14:43 +00006375- Patch #1816: Added sys.flags structseq. It exposes the status of
6376 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006377
Georg Brandl3ee81df2008-05-17 18:14:43 +00006378- Objects/structseq.c: Implemented new structseq representation. The
6379 patch makes structseqs (e.g. the return value of os.stat) more
6380 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006381
Georg Brandl3ee81df2008-05-17 18:14:43 +00006382- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00006404 and INF. float("nan"), float("inf") and float("-inf") now work on
6405 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006406
Georg Brandl3ee81df2008-05-17 18:14:43 +00006407- Compiler now generates simpler and faster code for dictionary
6408 literals. The oparg for BUILD_MAP now indicates an estimated
6409 dictionary size. There is a new opcode, STORE_MAP, for adding
6410 entries to the dictionary.

6446 executed code is closing a paused generator.

6453
Georg Brandl21e99f42010-03-07 15:23:59 +00006454- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006455 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6456 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006457
Georg Brandl3ee81df2008-05-17 18:14:43 +00006458- Issue #1686386: Tuple's tp_repr did not take into account the
6459 possibility of having a self-referential tuple, which is possible
6460 from C code. Nor did object's tp_str consider that a type's tp_str
6461 could do something that could lead to an inifinite recursion.
6462 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6463 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006464
Georg Brandl3ee81df2008-05-17 18:14:43 +00006465- Issue #1164: It was possible to trigger deadlock when using the
6466 'print' statement to write to a file since the GIL was not released
6467 as needed. Now PyObject_Print() does the right thing along with
6468 various tp_print implementations of the built-in types and those in
6469 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006470
Georg Brandl3ee81df2008-05-17 18:14:43 +00006471- Issue #1147: Exceptions were directly allowing string exceptions in
6472 their throw() method even though string exceptions no longer
6473 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00006477
Brett Cannon1e534b52007-09-07 04:18:30 +00006478- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006479 PyObject_Call() never calling back out to Python code to trigger
6480 recursion depth updates/checks. Required the creation of a static
6481 RuntimeError instance in case normalizing an exception put the
6482 recursion check value past its limit. Fixes crashers
6483 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00006498- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006499 __*__ attributes. (Some already existed, e.g., __doc__ and
6500 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006501
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006502- Add -3 option to the interpreter to warn about features that are
6503 deprecated and will be changed/removed in Python 3.0.
6504
Georg Brandl2134e752007-05-21 20:34:16 +00006505- Patch #1686487: you can now pass any mapping after '**' in function
6506 calls.
6507
Collin Winter62903052007-05-18 23:11:24 +00006508- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006509 "except E as target:". This is to provide forwards compatibility
6510 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006517- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006518 setting a plain string, ie don't expand to single letter identifiers.
6519
Raymond Hettinger13936692007-04-11 18:40:58 +00006520- Request #1191699: Slices can now be pickled.
6521
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006522- Request #1193128: str.translate() now allows a None argument for
6523 translations that only remove characters without re-mapping the
6524 remaining characters.
6525
Georg Brandl5cb76c12007-03-21 09:00:39 +00006526- Patch #1682205: a TypeError while unpacking an iterable is no longer

6530
Guido van Rossum143b5642007-03-23 04:58:42 +00006531- Bug #1683368: The object.__init__() and object.__new__() methods are
6532 now stricter in rejecting excess arguments. The only time when
6533 either allows excess arguments is when it is not overridden and the
6534 other one is. For backwards compatibility, when both are
6535 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006536 warning later). Also, type.__init__() insists on the same signature
6537 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006538
Georg Brandl3ee81df2008-05-17 18:14:43 +00006539- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6540 object to complex using its __complex__() method before falling back
6541 to the __float__() method. Therefore, the functions in the cmath
6542 module now can operate on objects that define a __complex__()
6543 method.

6554 its type.

6560
Georg Brandl7b9c5552007-03-12 14:30:05 +00006561- Bug #1678647: write a newline after printing an exception in any
6562 case, even when converting the value to a string failed.
6563
Georg Brandl871f1bc2007-03-12 13:17:36 +00006564- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006565 its argument, if it exists. If not, it will work like before. This
6566 allows customizing the output of dir() in the presence of a
6567 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006575- Patch #1491866: change the complex() constructor to allow
6576 parthensized forms. This means complex(repr(x)) now works instead of
6577 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006578
Georg Brandlaa2321b2007-03-07 00:40:28 +00006579- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006580 makes the filenames the warning module prints much more sensible
6581 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00006594- Patch #1674228: when assigning a slice (old-style), check for the
6595 sq_ass_slice instead of the sq_slice slot.
6596
Georg Brandl3ee81df2008-05-17 18:14:43 +00006597- When printing an unraisable error, don't print exceptions. before
6598 the name. This duplicates the behavior whening normally printing
6599 exceptions.

7227 -- the failure just occurred later, with a more cumbersome
7228 exception.

7441 partial fix for Bug #1574584.
7442
Georg Brandl3ee81df2008-05-17 18:14:43 +00007443- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007509- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7510 with RFC 3207 and forgets any knowledge obtained from the server not
7511 obtained from the TLS negotiation itself. Patch contributed by Bill
7512 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007513
Georg Brandl3ee81df2008-05-17 18:14:43 +00007514- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007515 that the SMTP.starttls() caller no longer needs to call ehlo()
7516 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007517 does not claim to support starttls. Adds the
7518 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
7519 Fenner.

Georg Brandl56112892008-01-20 13:59:46 +00007556- Patch #1648: added ``sys.getprofile()`` and ``sys.gettrace()``.
7557
Georg Brandl3ee81df2008-05-17 18:14:43 +00007558- Patch #1663329: added ``os.closerange()`` function to quickly close

Georg Brandl3ee81df2008-05-17 18:14:43 +00007561- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00007562 works as expected. ``mmap.find`` also takes an optional ``end``
7563 parameter.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007573- itertools.chain() now has an alternate constructor,

7588 contents before adding elements from the iterable. This fix brings
7589 the behavior into line with that for list.__init__().

7599 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7600 silently miscode subclasses of those types. Now, it raises a
7601 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007602

Georg Brandl3ee81df2008-05-17 18:14:43 +00007617 time so that opening a database previously created with the DB_DUP
7618 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7619 opens. Specifically: dictionary assignment to a DB object will
7620 replace all values for a given key when the database allows
7621 duplicate values. DB users should use DB.put(k, v) when they want
7622 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007623

7629 characters with ASCII value less than 32. Also, it correctly quotes
7630 dots only if they occur on a single line, as opposed to the previous
7631 behavior of quoting dots if they are the second character of any
7632 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007633

7956
Georg Brandl3ee81df2008-05-17 18:14:43 +00007957- Unified naming convention for free lists and their limits. All free
7958 lists in Object/ are named ``free_list``, the counter ``numfree``
7959 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
7960 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00007961
Georg Brandl3ee81df2008-05-17 18:14:43 +00007962- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7963 to ``PyTuple_SetItem``, it can be used to populate a brand new
7964 frozenset; but it does not steal a reference to the added item.

7976
Georg Brandl3ee81df2008-05-17 18:14:43 +00007977- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7978 of w# format code incorrectly truncated the length to an int, even
7979 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7980 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007981
Georg Brandl3ee81df2008-05-17 18:14:43 +00007982- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

8000- Fix some leftovers from the conversion from int to Py_ssize_t
8001 (relevant to strings and sequences of more than 2**31 items).
8002
8003- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8004 outside of pystate.c and should not be necessary.
8005
Georg Brandl3ee81df2008-05-17 18:14:43 +00008006- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8007 absolute imports. In earlier versions they might have used relative
8008 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008009
Georg Brandl3ee81df2008-05-17 18:14:43 +00008010- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8011 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008012
Georg Brandl3ee81df2008-05-17 18:14:43 +00008013- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

8021 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
8022 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
8023 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00008024

Georg Brandl3ee81df2008-05-17 18:14:43 +00008038- Removed the macfs module. It had been deprecated since Python 2.5.
8039 This lead to the deprecation of macostools.touched() as it relied
8040 solely on macfs and was a no-op under OS X.
