Nadeem Vawda6cad3712012-11-05 00:55:06 +01001455 successive calls after EOF in unused_data, instead of only saving the argument
Nadeem Vawda252f4dc2012-11-11 02:14:15 +01001456 to the last call. decompressobj().flush() now correctly sets unused_data and

Ned Deily18fae3f2013-01-31 01:24:55 -08001780- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1781 In particular, fix extension module build failures when trying to use
1782 32-bit-only installer Pythons on systems with Xcode 4 (currently
1783 OS X 10.8, 10.7, and optionally 10.6).
1784 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1785 * Since Xcode 4 removes ppc support, extension module builds now
1786 check for ppc compiler support and by default remove ppc and
1787 ppc64 archs when they are not available.
1788 * Extension module builds now revert to using system installed
1789 headers and libs (/usr and /System/Library) if the SDK used
1790 to build the interpreter is not installed or has moved.
1791 * Try to avoid building extension modules with deprecated
1792 and problematic Apple llvm-gcc compiler. If original compiler
1793 is not available, use clang instead by default.

2148 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deily0d0ea482012-02-10 12:59:06 +01002224- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2225 Distutils-based packages with C extension modules may fail because
2226 Apple has removed gcc-4.2, the version used to build python.org
2227 64-bit/32-bit Pythons. If the user does not explicitly override
2228 the default C compiler by setting the CC environment variable,
2229 Distutils will now attempt to compile extension modules with clang
2230 if gcc-4.2 is required but not found. Also as a convenience, if
2231 the user does explicitly set CC, substitute its value as the default
2232 compiler in the Distutils LDSHARED configuration variable for OS X.
2233 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2234 SDK, neither of which are available in Xcode 4. This change does not
2235 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002485- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2486 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2487 interpreter process. This could cause failures in non-Distutils subprocesses
2488 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002489 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002490 deployment target only in the environment of each build subprocess. It is
2491 still possible to globally override the default by setting
2492 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2493 greater or equal to the default value, the value with which the interpreter
2494 was built.

2523 updating the check interval, so if the user decreases the check interval,
2524 the ticker doesn't have to wind down to zero from the old starting point
2525 before the new interval takes effect. And if the user increases the
2526 interval, it makes sure the new limit takes effect right away rather have an
2527 early task switch before recognizing the new interval.

3506
Raymond Hettinger20397532010-09-12 02:11:45 +00003507- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3508 This prevents user-created self-referencing ordered dictionaries from
3509 becoming permanently uncollectable GC garbage. The downside is that
3510 removing __del__ means that the internal doubly-linked list has to wait for
3511 GC collection rather than freeing memory immediately when the refcnt drops
3512 to zero.

3973 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3974 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

3986 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00004331 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
4332 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
4333 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

4354-----------------
4355
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004356- Issue #7301: Add environment variable $PYTHONWARNINGS.
4357
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004358- Issue #8329: Don't return the same lists from select.select when no fds are
4359 changed.
4360
Georg Brandlfee0f442010-05-22 21:26:21 +00004361- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004362 on 64-bit machines. The shift count for either left or right shift is
4363 permitted to be up to sys.maxsize.

4370
Georg Brandlfee0f442010-05-22 21:26:21 +00004371- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4372 with a non-empty format string. This is an effort to future-proof user
4373 code. If a derived class does not currently implement __format__ but later
4374 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004375 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004376 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004377

4408
Georg Brandlfee0f442010-05-22 21:26:21 +00004409- Issue #8257: The Decimal construct now accepts a float instance directly,
4410 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004411
4412 >>> Decimal(1.1)
4413 Decimal('1.100000000000000088817841970012523233890533447265625')
4414
Raymond Hettinger34c35b22010-04-03 10:22:00 +00004415- collections.Counter() now supports a subtract() method.
4416
Georg Brandlfee0f442010-05-22 21:26:21 +00004417- The functools module now has a total_ordering() class decorator to simplify
4418 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00004420- The functools module also adds cmp_to_key() as a tool to transition old-style
4421 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00004422
Georg Brandlfee0f442010-05-22 21:26:21 +00004423- Issue #8294: The Fraction constructor now accepts Decimal and float instances
4424 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00004425
Georg Brandlfee0f442010-05-22 21:26:21 +00004426- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4427 InvalidOperation instead of returning False. (Comparisons involving a quiet
4428 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4429 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004430
Georg Brandlfee0f442010-05-22 21:26:21 +00004431- Issue #2531: Comparison operations between floats and Decimal instances now
4432 return a result based on the numeric values of the operands; previously they
4433 returned an arbitrary result based on the relative ordering of id(float) and
4434 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004435
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004436- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004437 argument `-` which tells it to read files to compile from stdin. Each line is
4438 read on demand and the named file is compiled immediately. (Original patch by
4439 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004440
Georg Brandlfee0f442010-05-22 21:26:21 +00004441- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00004444- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4445 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004446 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00004447
Georg Brandlfee0f442010-05-22 21:26:21 +00004448- Comparisons using one of <, <=, >, >= between a complex instance and a
4449 Fractions instance now raise TypeError instead of returning True/False. This
4450 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4451 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00004452

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004462- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00004463 didn't support chflags() (for example ZFS under FreeBSD). The error is now
4464 silenced.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00004550- Issue #8300: When passing a non-integer argument to struct.pack with any
4551 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00004555- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4556 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4557 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004558 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4559 inconsistent: __int__ was used for some integer codes but not for others, and
4560 the set of integer codes for which it was used differed between native packing
4561 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00004773- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
4774 now also used by regrtest to run all the tests in a temporary directory. The
4775 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
4776 Xicluna who helped with the patch.

4793 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00004794 library would return a bogus result; on Solaris, it was possible to crash the

Georg Brandlba83f822010-03-14 09:50:54 +00004813- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4814 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4815 returning NULL. The macro now returns a statically allocated empty string
4816 instead.

4826 strings,
4827 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
4828 numeric strings corresponding to subnormal values,
4829 (3) a memory leak for some values large enough to cause overflow, and
4830 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00004861- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00004862 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00004863 Also, raise ValueError rather than TypeError when an unknown TIPC address
4864 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004868- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004869 file position when calling `truncate()`. It would previously change the file
4870 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004871 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4872
Georg Brandlba83f822010-03-14 09:50:54 +00004873- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4874 class used to represent files stored inside an archive. The new
4875 implementation is significantly faster and can be wrapped in a
4876 ``io.BufferedReader`` object for more speedups. It also solves an issue
4877 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4878 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00004888- Issue #7748: Since unicode values are supported for some metadata options in
4889 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4890 encoded string for them. This ensures that the upload and register commands
4891 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00004968- The ``__complex__()`` method is now looked up on the class of instances to
4969 make it consistent with other special methods.

4973
Mark Dickinson1b34d252010-01-01 17:27:30 +00004974- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004975 DeprecationWarning when passed a float argument where an integer was expected.
4976 These functions and methods now raise TypeError instead. The majority of the
4977 effects of this change are in the extension modules, but some core functions
4978 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4979 and many unicode/str methods.

4993 of integers: the result of a/b is now correctly rounded for ints a and b (at
4994 least on IEEE 754 platforms), and in particular does not depend on the
4995 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00005004 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00005161- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5162 decimal string that's guaranteed to round back to x under correct rounding
5163 (with round-half-to-even rounding mode). Previously it gave a string based on
5164 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5165 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5166 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005167
Georg Brandlba83f822010-03-14 09:50:54 +00005168- Issue #7117: On almost all platforms: float-to-string and string-to-float
5169 conversions within Python are now correctly rounded. Places these conversions
5170 occur include: str for floats and complex numbers; the float and complex
5171 constructors; old-style and new-style numeric formatting; serialization and
5172 deserialization of floats and complex numbers using marshal, pickle and json;
5173 parsing of float and imaginary literals in Python code; Decimal-to-float
5174 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005175
Georg Brandlba83f822010-03-14 09:50:54 +00005176 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5177 providing correctly-rounded strtod and dtoa C functions. This code is
5178 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5179 the C compiler. There may be a small number of platforms on which correct
5180 operation of this code cannot be guaranteed, so the code is not used: notably,
5181 this applies to platforms where the C double format is not IEEE 754 binary64,
5182 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5183 and Python's configure script is unable to determine how to change the FPU
5184 precision. On these platforms conversions use the platform strtod and dtoa,
5185 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005186
Georg Brandlba83f822010-03-14 09:50:54 +00005187- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5188 uses the correctly-rounded string <-> float conversions described above (when
5189 available), and so produces correctly rounded results that will display nicely
5190 under the float repr. There are two related small changes: (1) round now
5191 accepts any class with an ``__index__()`` method for its second argument (but
5192 no longer accepts floats for the second argument), and (2) an excessively
5193 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5194 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005341- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5342 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5343 but with at least one decimal point and with a default precision
5344 of 12. Previously, the behavior the same but with a default precision of 6.
5345 This more closely matches ``str()``, and reduces surprises when adding
5346 alignment flags to the empty presentation type. This also affects the new
5347 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00005487- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
5488 existing .py counterpart, override the co_filename attributes of all code

5544
Georg Brandlba83f822010-03-14 09:50:54 +00005545- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5546 file objects with closefd=False. The file descriptor is still kept open but
5547 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00005571- On windows, ``os.chdir()`` given unicode was not working if

5573 this code path is really executed because I cannot move to such directory on
5574 win2k)

5577 element is temporarily replaced with an equivalent frozenset. But the
5578 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00005599- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5600 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5601 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5602 of using the replace error handler in PyUnicode_DecodeUTF8().
5603
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005604- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00005607- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

5609 gives improved memory leak detection when running under Valgrind, while taking
5610 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00006857 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip

6979
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006980- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6981 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6982 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6983 ``printf`` function, whereas PyString_FromFormat has an independent
6984 implementation and uses "%zd" on all platforms for size_t values.
6985 This makes a difference on win64, where ``printf`` needs "%Id" to display
6986 64bit values.

7004
Vinay Sajip35e3b032008-09-01 14:33:59 +00007005- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007006 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7007 mechanism. In the process, fix a bug where isinstance() and issubclass(),

7009 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7010 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007149What's New in Python 2.6 beta 3?
7150================================
7151
Barry Warsaw07a4a382008-08-21 01:15:08 +00007152*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007153
7154Core and Builtins
7155-----------------
7156
Guido van Rossumf8402962008-08-20 15:01:50 +00007157- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7158 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7159 extensions do not automatically benefit from the class attribute
7160 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7161 to their tp_flags field if they care. This is a backwards
7162 compatibility feature; in 3.0, all types will use the cache by
7163 default.
7164
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007165- Keyword arguments can now follow starred arguments. (``f(a, *args,
7166 keyword=23)`` is now valid syntax.)
7167
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007168- ctypes function pointers that are COM methods have a boolean True
7169 value again.
7170
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007171- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7172 by denying s# to parse objects that have a releasebuffer procedure,
7173 and introducing s*.
7174
Georg Brandl1e13ea92008-08-11 09:07:59 +00007175- Issue #3537: Fix an assertion failure when an empty but presized dict
7176 object was stored in the freelist.
7177
Mark Dickinsonb6467572008-08-04 21:30:09 +00007178- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7179 ValueError consistently across platforms.
7180
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007181- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7182 (64bit Unix, for example), unichr() would truncate its argument and return
7183 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7184
Neal Norwitze7d8be82008-07-31 17:17:14 +00007185- Apply security patches from Apple.
7186
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007187- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7188 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7189
Antoine Pitrou92f82162008-07-25 22:22:08 +00007190- Issue #1819: function calls with several named parameters are now on
7191 average 35% faster (as measured by pybench).
7192
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007193- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7194 the python debugger steps into a class statement: the free variables (local
7195 variables defined in an outer scope) would be deleted from the outer scope.
7196
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007197- Issue #2620: Overflow checking when allocating or reallocating memory
7198 was not always being done properly in some python types and extension
7199 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7200 all been updated to perform better checks and places in the code that
7201 would previously leak memory on the error path when such an allocation
7202 failed have been fixed.
7203

7205-------
7206
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007207- Issue #3612: Added some missing basic types in ctypes.wintypes.
7208
Benjamin Petersone977ad42008-08-20 01:42:01 +00007209- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7210 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7211
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007212- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7213 version reported by these tools does not necessarily follow the python
7214 version numbering scheme, so the module is less strict when parsing it.
7215
Nick Coghlanf70385a2008-08-18 12:42:46 +00007216- Issue #2235: Added Py3k warnings for types which will become unhashable
7217 under the stricter __hash__ inheritance rules in 3.0. Several types
7218 which did not meet the rules for hash invariants and were already
7219 unhashable in 3.0 have now been explicitly flagged as unhashable in
7220 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7221 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7222
Brett Cannon88f801d2008-08-18 00:46:22 +00007223- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7224 imported into the module but exposed as part of the module's API.
7225
Brett Cannon7b96f072008-08-18 00:41:11 +00007226- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7227
Brett Cannon46225e72008-08-18 00:36:52 +00007228- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
7229
Brett Cannon25c9d6a2008-08-17 22:10:11 +00007230- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7231
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007232- Issue #3575: Incremental decoder's decode function now takes bytearray
7233 by using 's*' instead of 't#'.
7234
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007235- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007236 fails unicode conversion on 2nd parameter. (windows only)
7237
Georg Brandl222e2082010-08-01 22:27:39 +00007238- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007239 in a redirect.
7240
Brett Cannonabe423e2008-08-16 21:47:07 +00007241- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007242 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007243
Facundo Batistaeb90b782008-08-16 14:44:07 +00007244- Issue #2776: fixed small issue when handling an URL with double slash
7245 after a 302 response in the case of not going through a proxy.
7246
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007247- Issue #2676: in the email package, content-type parsing was hanging on
7248 pathological input because of quadratic or exponential behaviour of a
7249 regular expression.
7250
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007251- Issue #3476: binary buffered reading through the new "io" library is now
7252 thread-safe.
7253
Brett Cannonbf3157b2008-08-14 05:00:03 +00007254- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7255 since mimetools itself is deprecated. Because modules are cached, all
7256 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7257
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007258- Issue #3134: shutil referenced undefined WindowsError symbol.
7259
Robert Schuppenies14646332008-08-10 11:01:53 +00007260- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7261 menu entries were not deleted.
7262
Brett Cannon83e81842008-08-09 23:30:55 +00007263- Copied the implementation of reduce() to _functools.reduce() to have a
7264 version that did not raise a DeprecationWarning under -3.
7265
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007266- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7267 a MemoryError rather than silently stop the iteration.
7268
Guido van Rossum59ce9012008-08-09 14:55:34 +00007269- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7270 to _sre.compile() will now be rejected. This should not affect anybody
7271 since the re.compile() function never generates invalid re-bytecode.
7272
Skip Montanaroa032bf42008-08-08 22:52:51 +00007273- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7274 upon first access it can be automatically initialized from the csv file if
7275 it wasn't initialized during instantiation.
7276
Brett Cannon3aa2a492008-08-06 22:28:09 +00007277- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7278 the reload() built-in has been removed.
7279
Brett Cannon7e30b672008-08-04 21:52:25 +00007280- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007281 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

7284 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
7285 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
7286 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00007287
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00007288- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
7289 raised an AttributeError.
7290
Benjamin Peterson01a24322008-07-28 23:35:27 +00007291- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00007292 asking for a specific length. This problem only affected files opened
7293 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007294
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00007295- Issue #3449: Update decimal module to use most recent specification
7296 (v. 1.68) and tests (v. 2.58) from IBM.
7297
Georg Brandl222e2082010-08-01 22:27:39 +00007298- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00007299

Raymond Hettinger8c664e82008-07-25 18:43:33 +00007301 on a closed shelf.
7302
Georg Brandlf9efabb2008-07-23 15:16:45 +00007303- Deprecate the "ast" parser function aliases.
7304
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007305- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
7306
7307- Issue #3303: Fix a crash in locale.strcoll() when calling it with
7308 invalid arguments.
7309
7310- Issue #3302: Fix several crashes when calling locale's gettext functions
7311 with None arguments.
7312
7313- Issue #3389: Allow resolving dotted names for handlers in logging
7314 configuration files.
7315
7316- Deprecate the sunaudio module for removal in Python 3.0.
7317
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00007318- Issue #3394: zipfile.writestr sets external attributes when passed a
7319 file name rather than a ZipInfo instance, so files are extracted with
7320 mode 0600 rather than 000 under Unix.
7321
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007322- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7323 argument in python 2.5, this broke code that subclassed Popen to include its
7324 own poll method. Fixed my moving _deadstate to an _internal_poll method.

7333
Nick Coghlan6e8fef02008-08-18 13:14:22 +00007334- Issue #2235: the C API function PyObject_HashNotImplemented and its
7335 interaction with the tp_hash slot (added in 2.6b2) are now documented
7336
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007337- Issue #643841: The language reference now provides more detailed
7338 coverage of the lookup process for special methods. The disclaimers
7339 regarding lack of coverage of new-style classes have also been
7340 removed, since the coverage is now fairly reasonable.

7345
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007346*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00007348Core and Builtins
7349-----------------
7350
Georg Brandl3e483f62008-07-16 22:57:41 +00007351- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7352 its methods now allow for items objects that can be converted to
7353 an integer using operator.index().
7354
Mark Dickinson64b7e502008-07-16 09:40:03 +00007355- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7356 produced a ValueError instead of giving the correct float.
7357
Eric Smitha5fa5a22008-07-16 00:11:49 +00007358- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7359 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7360
Mark Dickinson7103aa42008-07-15 19:08:33 +00007361- Issue #3008: the float type has a new instance method 'float.hex'
7362 and a new class method 'float.fromhex' to convert floating-point
7363 numbers to and from hexadecimal strings, respectively.
7364
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007365- Issue #2235: __hash__ is once again inherited by default. To allow
7366 collections.Hashable to remain meaningful in the presence of the
7367 default hash implementation (object.__hash__), it is now possible
7368 to explicit block inheritance of hash by setting __hash__=None at
7369 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7370 level.
7371
Nick Coghlanb028f502008-07-13 14:52:36 +00007372- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7373 the parent module cannot be found while performing an absolute import.
7374 This means that an incorrectly defined __package__ attribute will
7375 now only prevent relative imports in that module rather than causing
7376 all imports from that module to fail.
7377
Nick Coghlan14ff9942008-07-08 14:21:42 +00007378- Issue #2517: Allow unicode messages in Exceptions again by correctly
7379 bypassing the instance dictionary when looking up __unicode__ on
7380 new-style classes.
7381
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007382- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7383 set to a custom object whose write() method happens to install
7384 another file in sys.stdout.

Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007386- Issue #3088: Corrected a race condition in classes derived from
7387 threading.local: the first member set by a thread could be saved in
7388 another thread's dictionary.
7389
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007390- Issue #3004: Minor change to slice.indices(): the start and stop
7391 arguments are now treated identically, making the behaviour easier
7392 to describe and understand. For example, slice(None, -10,
7393 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7394 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7395 10, -1).
7396
Georg Brandl278fc502008-07-19 12:46:12 +00007397- Issue #3219: Calling a function with repeated keyword arguments,
7398 f(a=2, a=23), would not cause a syntax error. This was a regression
7399 from 2.4 caused by the switch to the new compiler.

7410 error when they failed.

Georg Brandl5cc774e2008-06-11 20:28:06 +00007847 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007848
7849 This is controlled by the configure argument ``--with-universal-archs``:
7850
7851 - ``--with-universal-archs=all``: install 4-way universal
7852
7853 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7854
7855 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7856
7857 This option should be used in combination with ``--enable-universalsdk=``.
7858
7859 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00007908- Issue #1631171: Re-implement the 'warnings' module in C (the
7909 original Python code has been kept as backup). This will allow for
7910 using the 'warning's machinery in such places as the parser where
7911 use of pure Python code is not possible. Both the ``showarning()``
7912 and ``formatwarning()`` gain an optional 'line' argument which is
7913 not called by default for backwards-compatibility reasons. Setting
7914 ``warnings.showwarning()`` to an implementation that lacks support
7915 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007970- Issue #2385: distutils.core.run_script() makes __file__ available,
7971 so the controlled environment will more closely mirror the typical
7972 script environment. This supports setup.py scripts that refer to
7973 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007978- Issue #2550: The approach used by client/server code for obtaining
7979 ports to listen on in network-oriented tests has been refined in an
7980 effort to facilitate running multiple instances of the entire
7981 regression test suite in parallel without issue.
7982 test_support.bind_port() has been fixed such that it will always
7983 return a unique port -- which wasn't always the case with the
7984 previous implementation, especially if socket options had been set
7985 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7986 new implementation of bind_port() will actually raise an exception
7987 if it is passed an AF_INET/SOCK_STREAM socket with either the
7988 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7989 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7990 the socket it's been passed. This currently only applies to
7991 Windows. This option prevents any other sockets from binding to the
7992 host/port we've bound to, thus removing the possibility of the
7993 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7994 when a second SOCK_STREAM socket binds and accepts to a host/port
7995 that's already been bound by another socket. The optional preferred
7996 port parameter to bind_port() has been removed. Under no
7997 circumstances should tests be hard coding ports!
7998
7999 test_support.find_unused_port() has also been introduced, which will
8000 pass a temporary socket object to bind_port() in order to obtain an
8001 unused port. The temporary socket object is then closed and
8002 deleted, and the port is returned. This method should only be used
8003 for obtaining an unused port in order to pass to an external program
8004 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8005 a parameter to a server-oriented class that doesn't give you direct
8006 access to the underlying socket used.
8007
8008 Finally, test_support.HOST has been introduced, which should be used
8009 for the host argument of any relevant socket calls (i.e. bind and
8010 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008011
8012 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008013 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008014 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8015 test_asynchat and test_socket_ssl.
8016
Georg Brandl3ee81df2008-05-17 18:14:43 +00008017 It is now possible for multiple instances of the regression test
8018 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008297- Added the future_builtins module, which contains hex() and oct().
8298 These are the PEP 3127 version of these functions, designed to be
8299 compatible with the hex() and oct() builtins from Python 3.0. They
8300 differ slightly in their output formats from the existing, unchanged
8301 Python 2.6 builtins. The expected usage of the future_builtins
8302 module is:
8303 from future_builtins import hex, oct
8304
Eric Smith7ef40bf2008-02-20 23:34:22 +00008305- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8306 exponents for exponents with absolute value < 100. Follows C99
8307 standard. This is a change on Windows, which would use 3 digits.
8308 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8309 so that any alterations it does to the resulting string will be
8310 available in stringlib/formatter.h (for float.__format__).
8311
Eric Smith5a3c1352008-02-19 13:21:56 +00008312- Implemented PEP 3101, Advanced String Formatting. This adds a new
8313 builtin format(); a format() method for str and unicode; a
8314 __format__() method to object, str, unicode, int, long, float, and
8315 datetime; the class string.Formatter; and the C API
8316 PyObject_Format().
8317
Georg Brandl3ee81df2008-05-17 18:14:43 +00008318- Fixed several potential crashes, all caused by specially crafted
8319 __del__ methods exploiting objects in temporarily inconsistent
8320 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008321
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008322- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008323 prevent a possible crash: an Abstract Base Class would try to access
8324 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008325

Georg Brandl3ee81df2008-05-17 18:14:43 +00008329- Clear all free lists during a gc.collect() of the highest generation
8330 in order to allow pymalloc to free more arenas. Python may give back
8331 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008332
Georg Brandl3ee81df2008-05-17 18:14:43 +00008333- Issue #2045: Fix an infinite recursion triggered when printing a
8334 subclass of collections.defaultdict, if its default_factory is set
8335 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008336
Christian Heimesf75dbef2008-02-08 00:11:31 +00008337- Fixed a minor memory leak in dictobject.c. The content of the free
8338 list was not freed on interpreter shutdown.
8339
Georg Brandl21e99f42010-03-07 15:23:59 +00008340- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008341 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008342
Georg Brandl3ee81df2008-05-17 18:14:43 +00008343- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8344 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008345 to compact the internal free lists of pre-allocted ints and floats.
8346
Georg Brandl3ee81df2008-05-17 18:14:43 +00008347- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8348 calls. Python expected the return type int but the fork familie
8349 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008350
Georg Brandl3ee81df2008-05-17 18:14:43 +00008351- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00008363- Patch #1473257: generator objects gain a gi_code attribute. This is
8364 the same object as the func_code attribute of the function that
8365 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008366
Georg Brandl3ee81df2008-05-17 18:14:43 +00008367- Issue #1920: "while 0" statements were completely removed by the
8368 compiler, even in the presence of an "else" clause, which is
8369 supposed to be run when the condition is false. Now the compiler
8370 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008371
Guido van Rossumeead05f2008-01-24 18:21:02 +00008372- A few crashers fixed: weakref_in_del.py (issue #1377858);
8373 loosing_dict_ref.py (issue #1303614, test67.py);
8374 borrowed_ref_[34].py (not in tracker).
8375
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008376- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008377 suppressed while an extension is loaded by calling SetErrorMode in
8378 dynload_win.c. The error is still reported properly.
8379
Georg Brandl3ee81df2008-05-17 18:14:43 +00008380- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008381 several extension methods and modules do not work without unicode
8382 support.
8383
Georg Brandl26543b12008-01-21 18:36:51 +00008384- Issue #1882: when compiling code from a string, encoding cookies in the
8385 second line of code were not always recognized correctly.
8386
Georg Brandl14404b62008-01-19 19:27:05 +00008387- Issue #1679: "0x" was taken as a valid integer literal.
8388
Georg Brandl6caad7d2008-01-26 14:19:22 +00008389- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008390 added.
8391
Christian Heimesc94e2b52008-01-14 04:13:37 +00008392- sys.float_info / PyFloat_GetInfo: The floating point information
8393 object was converted from a dict to a specialized structseq object.
8394
Georg Brandl3ee81df2008-05-17 18:14:43 +00008395- Patch #1816: Added sys.flags structseq. It exposes the status of
8396 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008397
Georg Brandl3ee81df2008-05-17 18:14:43 +00008398- Objects/structseq.c: Implemented new structseq representation. The
8399 patch makes structseqs (e.g. the return value of os.stat) more
8400 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008401
Georg Brandl3ee81df2008-05-17 18:14:43 +00008402- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00008424 and INF. float("nan"), float("inf") and float("-inf") now work on
8425 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008426
Georg Brandl3ee81df2008-05-17 18:14:43 +00008427- Compiler now generates simpler and faster code for dictionary
8428 literals. The oparg for BUILD_MAP now indicates an estimated
8429 dictionary size. There is a new opcode, STORE_MAP, for adding
8430 entries to the dictionary.

Neal Norwitz44f326e2007-10-05 05:29:17 +00008472- Fix warnings found by the new version of the Coverity checker.
8473
Georg Brandl21e99f42010-03-07 15:23:59 +00008474- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008475 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8476 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008477
Georg Brandl3ee81df2008-05-17 18:14:43 +00008478- Issue #1686386: Tuple's tp_repr did not take into account the
8479 possibility of having a self-referential tuple, which is possible
8480 from C code. Nor did object's tp_str consider that a type's tp_str
8481 could do something that could lead to an inifinite recursion.
8482 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8483 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008484
Georg Brandl3ee81df2008-05-17 18:14:43 +00008485- Issue #1164: It was possible to trigger deadlock when using the
8486 'print' statement to write to a file since the GIL was not released
8487 as needed. Now PyObject_Print() does the right thing along with
8488 various tp_print implementations of the built-in types and those in
8489 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008490
Georg Brandl3ee81df2008-05-17 18:14:43 +00008491- Issue #1147: Exceptions were directly allowing string exceptions in
8492 their throw() method even though string exceptions no longer
8493 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008494
Georg Brandl3ee81df2008-05-17 18:14:43 +00008495- Issue #1096: Prevent a segfault from getting the repr of a very
8496 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008497
Brett Cannon1e534b52007-09-07 04:18:30 +00008498- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008499 PyObject_Call() never calling back out to Python code to trigger
8500 recursion depth updates/checks. Required the creation of a static
8501 RuntimeError instance in case normalizing an exception put the
8502 recursion check value past its limit. Fixes crashers
8503 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008504

Neal Norwitz0ac60192007-05-27 04:08:54 +00008518- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008519 __*__ attributes. (Some already existed, e.g., __doc__ and
8520 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008521
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008522- Add -3 option to the interpreter to warn about features that are
8523 deprecated and will be changed/removed in Python 3.0.
8524
Georg Brandl2134e752007-05-21 20:34:16 +00008525- Patch #1686487: you can now pass any mapping after '**' in function
8526 calls.
8527
Collin Winter62903052007-05-18 23:11:24 +00008528- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008529 "except E as target:". This is to provide forwards compatibility
8530 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008531
Brett Cannon229cee22007-05-05 01:34:02 +00008532- Deprecate BaseException.message as per PEP 352.
8533
Georg Brandl3ee81df2008-05-17 18:14:43 +00008534- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008535 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008537- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008538 setting a plain string, ie don't expand to single letter identifiers.
8539
Raymond Hettinger13936692007-04-11 18:40:58 +00008540- Request #1191699: Slices can now be pickled.
8541
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008542- Request #1193128: str.translate() now allows a None argument for
8543 translations that only remove characters without re-mapping the
8544 remaining characters.
8545
Georg Brandl5cb76c12007-03-21 09:00:39 +00008546- Patch #1682205: a TypeError while unpacking an iterable is no longer

8550
Guido van Rossum143b5642007-03-23 04:58:42 +00008551- Bug #1683368: The object.__init__() and object.__new__() methods are
8552 now stricter in rejecting excess arguments. The only time when
8553 either allows excess arguments is when it is not overridden and the
8554 other one is. For backwards compatibility, when both are
8555 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008556 warning later). Also, type.__init__() insists on the same signature
8557 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008558
Georg Brandl3ee81df2008-05-17 18:14:43 +00008559- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8560 object to complex using its __complex__() method before falling back
8561 to the __float__() method. Therefore, the functions in the cmath
8562 module now can operate on objects that define a __complex__()
8563 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008564
Georg Brandl3ee81df2008-05-17 18:14:43 +00008565- Patch #1623563: allow __class__ assignment for classes with
8566 __slots__. The old and the new class are still required to have the
8567 same slot names.

8573 ``object.__reduce_ex__()`` is called with an object that is faking
8574 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00008575
Georg Brandl3ee81df2008-05-17 18:14:43 +00008576- Patch #1680015: Don't modify __slots__ tuple if it contains an

8580
Georg Brandl7b9c5552007-03-12 14:30:05 +00008581- Bug #1678647: write a newline after printing an exception in any
8582 case, even when converting the value to a string failed.
8583
Georg Brandl871f1bc2007-03-12 13:17:36 +00008584- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008585 its argument, if it exists. If not, it will work like before. This
8586 allows customizing the output of dir() in the presence of a
8587 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008595- Patch #1491866: change the complex() constructor to allow
8596 parthensized forms. This means complex(repr(x)) now works instead of
8597 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008598
Georg Brandlaa2321b2007-03-07 00:40:28 +00008599- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008600 makes the filenames the warning module prints much more sensible
8601 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008602

Georg Brandl0fca97a2007-03-05 22:28:08 +00008614- Patch #1674228: when assigning a slice (old-style), check for the
8615 sq_ass_slice instead of the sq_slice slot.
8616
Georg Brandl3ee81df2008-05-17 18:14:43 +00008617- When printing an unraisable error, don't print exceptions. before
8618 the name. This duplicates the behavior whening normally printing
8619 exceptions.

9246 -- the failure just occurred later, with a more cumbersome
9247 exception.

Thomas Hellerd2ea4a22006-10-17 19:30:48 +00009458- ctypes callback functions only support 'fundamental' data types as
9459 result type. Raise an error when something else is used. This is a
9460 partial fix for Bug #1574584.
9461
Georg Brandl3ee81df2008-05-17 18:14:43 +00009462- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009518- The implementation of UnicodeError objects has been simplified
9519 (start and end attributes are now stored directly as Py_ssize_t
9520 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00009521
Georg Brandl3ee81df2008-05-17 18:14:43 +00009522- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9523 with RFC 3207 and forgets any knowledge obtained from the server not
9524 obtained from the TLS negotiation itself. Patch contributed by Bill
9525 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009526
Georg Brandl3ee81df2008-05-17 18:14:43 +00009527- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009528 that the SMTP.starttls() caller no longer needs to call ehlo()
9529 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009530 does not claim to support starttls. Adds the
9531 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
9532 Fenner.

9570
Georg Brandl3ee81df2008-05-17 18:14:43 +00009571- Patch #1663329: added ``os.closerange()`` function to quickly close

Georg Brandl3ee81df2008-05-17 18:14:43 +00009574- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00009575 works as expected. ``mmap.find`` also takes an optional ``end``

9601 contents before adding elements from the iterable. This fix brings
9602 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00009603
Georg Brandl3ee81df2008-05-17 18:14:43 +00009604- Added wide char functions to msvcrt module: getwch, getwche, putwch

9612 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9613 silently miscode subclasses of those types. Now, it raises a
9614 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009615

Georg Brandl3ee81df2008-05-17 18:14:43 +00009630 time so that opening a database previously created with the DB_DUP
9631 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9632 opens. Specifically: dictionary assignment to a DB object will
9633 replace all values for a given key when the database allows
9634 duplicate values. DB users should use DB.put(k, v) when they want
9635 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009636

9642 characters with ASCII value less than 32. Also, it correctly quotes
9643 dots only if they occur on a single line, as opposed to the previous
9644 behavior of quoting dots if they are the second character of any
9645 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009646

9973-----
9974
Georg Brandl3ee81df2008-05-17 18:14:43 +00009975- Unified naming convention for free lists and their limits. All free
9976 lists in Object/ are named ``free_list``, the counter ``numfree``
9977 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
9978 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009979
Georg Brandl3ee81df2008-05-17 18:14:43 +00009980- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9981 to ``PyTuple_SetItem``, it can be used to populate a brand new
9982 frozenset; but it does not steal a reference to the added item.

9991
9992- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9993 ``PyFloat_GetInfo()`` to the float API.
9994
Georg Brandl3ee81df2008-05-17 18:14:43 +00009995- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9996 of w# format code incorrectly truncated the length to an int, even
9997 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9998 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009999
Georg Brandl3ee81df2008-05-17 18:14:43 +000010000- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

10017
10018- Fix some leftovers from the conversion from int to Py_ssize_t
10019 (relevant to strings and sequences of more than 2**31 items).
10020
10021- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10022 outside of pystate.c and should not be necessary.
10023
Georg Brandl3ee81df2008-05-17 18:14:43 +000010024- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10025 absolute imports. In earlier versions they might have used relative
10026 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010027
Georg Brandl3ee81df2008-05-17 18:14:43 +000010028- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10029 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010030
Georg Brandl3ee81df2008-05-17 18:14:43 +000010031- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +000010037- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10038 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10039 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10040 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010041

Georg Brandl3ee81df2008-05-17 18:14:43 +000010054- Removed the macfs module. It had been deprecated since Python 2.5.
10055 This lead to the deprecation of macostools.touched() as it relied
10056 solely on macfs and was a no-op under OS X.
