888 unconsumed_tail. A bug in the handling of MemoryError when setting the

Ned Deily18fae3f2013-01-31 01:24:55 -08001211- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1212 In particular, fix extension module build failures when trying to use
1213 32-bit-only installer Pythons on systems with Xcode 4 (currently
1214 OS X 10.8, 10.7, and optionally 10.6).
1215 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1216 * Since Xcode 4 removes ppc support, extension module builds now
1217 check for ppc compiler support and by default remove ppc and
1218 ppc64 archs when they are not available.
1219 * Extension module builds now revert to using system installed
1220 headers and libs (/usr and /System/Library) if the SDK used
1221 to build the interpreter is not installed or has moved.
1222 * Try to avoid building extension modules with deprecated
1223 and problematic Apple llvm-gcc compiler. If original compiler
1224 is not available, use clang instead by default.

1579 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deily0d0ea482012-02-10 12:59:06 +01001655- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1656 Distutils-based packages with C extension modules may fail because
1657 Apple has removed gcc-4.2, the version used to build python.org
1658 64-bit/32-bit Pythons. If the user does not explicitly override
1659 the default C compiler by setting the CC environment variable,
1660 Distutils will now attempt to compile extension modules with clang
1661 if gcc-4.2 is required but not found. Also as a convenience, if
1662 the user does explicitly set CC, substitute its value as the default
1663 compiler in the Distutils LDSHARED configuration variable for OS X.
1664 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1665 SDK, neither of which are available in Xcode 4. This change does not
1666 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001916- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1917 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1918 interpreter process. This could cause failures in non-Distutils subprocesses
1919 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001920 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001921 deployment target only in the environment of each build subprocess. It is
1922 still possible to globally override the default by setting
1923 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1924 greater or equal to the default value, the value with which the interpreter
1925 was built.

1954 updating the check interval, so if the user decreases the check interval,
1955 the ticker doesn't have to wind down to zero from the old starting point
1956 before the new interval takes effect. And if the user increases the
1957 interval, it makes sure the new limit takes effect right away rather have an
1958 early task switch before recognizing the new interval.

2925 SSLSocket.sendto() to match the corresponding socket methods. Also,
2926 fix various SSLSocket methods to raise socket.error rather than an

2937
Raymond Hettinger20397532010-09-12 02:11:45 +00002938- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2939 This prevents user-created self-referencing ordered dictionaries from
2940 becoming permanently uncollectable GC garbage. The downside is that
2941 removing __del__ means that the internal doubly-linked list has to wait for
2942 GC collection rather than freeing memory immediately when the refcnt drops
2943 to zero.

R. David Murray7c4bf552010-08-25 01:45:57 +00002974- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2975 character years even if the message contains RFC822 two character years.

Antoine Pitrou3ebaed62010-08-21 19:17:25 +00002991- Issue #9617: Signals received during a low-level write operation aren't
2992 ignored by the buffered IO layer anymore.
2993

2996
Raymond Hettingera54b2da2010-08-17 19:03:06 +00002997- Issue #9626: the view methods for collections.OrderedDict() were returning

3012 patch by Jason V. Miller.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003402- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3403 start byte and the continuation byte(s) are now considered invalid, instead
3404 of the number of bytes specified by the start byte.
3405 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3406 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3407 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

3417 objects. (1) The comparison could incorrectly return True in some cases
3418 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00003763 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
3764 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's

3786-----------------
3787
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003788- Issue #7301: Add environment variable $PYTHONWARNINGS.
3789
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003790- Issue #8329: Don't return the same lists from select.select when no fds are
3791 changed.
3792
Georg Brandlfee0f442010-05-22 21:26:21 +00003793- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003794 on 64-bit machines. The shift count for either left or right shift is
3795 permitted to be up to sys.maxsize.
3796
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003797- Ensure that tokenization of identifiers is not affected by locale.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00003801- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
3802
Georg Brandlfee0f442010-05-22 21:26:21 +00003803- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3804 with a non-empty format string. This is an effort to future-proof user
3805 code. If a derived class does not currently implement __format__ but later
3806 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003807 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003808 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003809
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003810- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00003823- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003824 (SIGINT). If an error occurs while importing the site module, the error is

3840
Georg Brandlfee0f442010-05-22 21:26:21 +00003841- Issue #8257: The Decimal construct now accepts a float instance directly,
3842 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003843
3844 >>> Decimal(1.1)
3845 Decimal('1.100000000000000088817841970012523233890533447265625')
3846
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003847- collections.Counter() now supports a subtract() method.
3848
Georg Brandlfee0f442010-05-22 21:26:21 +00003849- The functools module now has a total_ordering() class decorator to simplify
3850 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00003852- The functools module also adds cmp_to_key() as a tool to transition old-style
3853 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00003854
Georg Brandlfee0f442010-05-22 21:26:21 +00003855- Issue #8294: The Fraction constructor now accepts Decimal and float instances
3856 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00003857
Georg Brandlfee0f442010-05-22 21:26:21 +00003858- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3859 InvalidOperation instead of returning False. (Comparisons involving a quiet
3860 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3861 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003862
Georg Brandlfee0f442010-05-22 21:26:21 +00003863- Issue #2531: Comparison operations between floats and Decimal instances now
3864 return a result based on the numeric values of the operands; previously they
3865 returned an arbitrary result based on the relative ordering of id(float) and
3866 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003867
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003868- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003869 argument `-` which tells it to read files to compile from stdin. Each line is
3870 read on demand and the named file is compiled immediately. (Original patch by
3871 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003872
Georg Brandlfee0f442010-05-22 21:26:21 +00003873- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00003876- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3877 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003878 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003879
Georg Brandlfee0f442010-05-22 21:26:21 +00003880- Comparisons using one of <, <=, >, >= between a complex instance and a
3881 Fractions instance now raise TypeError instead of returning True/False. This
3882 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3883 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00003884

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003894- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00003895 didn't support chflags() (for example ZFS under FreeBSD). The error is now
3896 silenced.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00003982- Issue #8300: When passing a non-integer argument to struct.pack with any
3983 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00003987- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
3988 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3989 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003990 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3991 inconsistent: __int__ was used for some integer codes but not for others, and
3992 the set of integer codes for which it was used differed between native packing
3993 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00004205- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
4206 now also used by regrtest to run all the tests in a temporary directory. The
4207 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
4208 Xicluna who helped with the patch.

4225 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00004226 library would return a bogus result; on Solaris, it was possible to crash the
4227 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +00004240- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
4241 and add the additional members returned in an OSVERSIONINFOEX structure. The
4242 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00004245- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4246 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4247 returning NULL. The macro now returns a statically allocated empty string
4248 instead.

4258 strings,
4259 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
4260 numeric strings corresponding to subnormal values,
4261 (3) a memory leak for some values large enough to cause overflow, and
4262 (4) a number of flaws that could lead to incorrectly rounded results.

4281
Georg Brandlba83f822010-03-14 09:50:54 +00004282- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in

Antoine Pitroud840e512010-02-04 20:20:18 +00004293- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00004294 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00004295 Also, raise ValueError rather than TypeError when an unknown TIPC address
4296 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004300- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004301 file position when calling `truncate()`. It would previously change the file
4302 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004303 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4304
Georg Brandlba83f822010-03-14 09:50:54 +00004305- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4306 class used to represent files stored inside an archive. The new
4307 implementation is significantly faster and can be wrapped in a
4308 ``io.BufferedReader`` object for more speedups. It also solves an issue
4309 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4310 Patch by Nir Aides.

Benjamin Peterson2deb5c72010-01-27 02:16:42 +00004312- Issue #7792: Registering non-classes to ABCs raised an obscure error.

Benjamin Petersona43f34c2010-01-25 03:31:13 +00004319
Georg Brandlba83f822010-03-14 09:50:54 +00004320- Issue #7748: Since unicode values are supported for some metadata options in
4321 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4322 encoded string for them. This ensures that the upload and register commands
4323 send the correct values to PyPI without any error.

4399
Georg Brandlba83f822010-03-14 09:50:54 +00004400- The ``__complex__()`` method is now looked up on the class of instances to
4401 make it consistent with other special methods.

4405
Mark Dickinson1b34d252010-01-01 17:27:30 +00004406- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004407 DeprecationWarning when passed a float argument where an integer was expected.
4408 These functions and methods now raise TypeError instead. The majority of the
4409 effects of this change are in the extension modules, but some core functions
4410 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4411 and many unicode/str methods.

4425 of integers: the result of a/b is now correctly rounded for ints a and b (at
4426 least on IEEE 754 platforms), and in particular does not depend on the
4427 internal representation of a long.

4435
Georg Brandlba83f822010-03-14 09:50:54 +00004436 These executables now work properly with the arch(1) command: ``arch -ppc
4437 python`` will start a universal binary version of python in PPC mode (unlike
4438 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00004594- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4595 decimal string that's guaranteed to round back to x under correct rounding
4596 (with round-half-to-even rounding mode). Previously it gave a string based on
4597 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4598 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4599 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004600
Georg Brandlba83f822010-03-14 09:50:54 +00004601- Issue #7117: On almost all platforms: float-to-string and string-to-float
4602 conversions within Python are now correctly rounded. Places these conversions
4603 occur include: str for floats and complex numbers; the float and complex
4604 constructors; old-style and new-style numeric formatting; serialization and
4605 deserialization of floats and complex numbers using marshal, pickle and json;
4606 parsing of float and imaginary literals in Python code; Decimal-to-float
4607 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004608
Georg Brandlba83f822010-03-14 09:50:54 +00004609 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4610 providing correctly-rounded strtod and dtoa C functions. This code is
4611 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4612 the C compiler. There may be a small number of platforms on which correct
4613 operation of this code cannot be guaranteed, so the code is not used: notably,
4614 this applies to platforms where the C double format is not IEEE 754 binary64,
4615 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4616 and Python's configure script is unable to determine how to change the FPU
4617 precision. On these platforms conversions use the platform strtod and dtoa,
4618 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004620- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4621 uses the correctly-rounded string <-> float conversions described above (when
4622 available), and so produces correctly rounded results that will display nicely
4623 under the float repr. There are two related small changes: (1) round now
4624 accepts any class with an ``__index__()`` method for its second argument (but
4625 no longer accepts floats for the second argument), and (2) an excessively
4626 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4627 raises an exception.

4776 but with at least one decimal point and with a default precision
4777 of 12. Previously, the behavior the same but with a default precision of 6.
4778 This more closely matches ``str()``, and reduces surprises when adding

Georg Brandlba83f822010-03-14 09:50:54 +00004920- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
4921 existing .py counterpart, override the co_filename attributes of all code

4977
Georg Brandlba83f822010-03-14 09:50:54 +00004978- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4979 file objects with closefd=False. The file descriptor is still kept open but
4980 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00005004- On windows, ``os.chdir()`` given unicode was not working if

5006 this code path is really executed because I cannot move to such directory on
5007 win2k)

Walter Dörwalded960ac2009-05-03 22:36:33 +00005032- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5033 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5034 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5035 of using the replace error handler in PyUnicode_DecodeUTF8().
5036
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005037- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00005040- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

5042 gives improved memory leak detection when running under Valgrind, while taking
5043 advantage of pymalloc at other times.

6289 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00006290 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
6291 the tests if DISPLAY is defined but can't be used.

6412
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006413- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6414 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6415 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6416 ``printf`` function, whereas PyString_FromFormat has an independent
6417 implementation and uses "%zd" on all platforms for size_t values.
6418 This makes a difference on win64, where ``printf`` needs "%Id" to display
6419 64bit values.

6425 object; previously an int would be returned for small values. the __long__
6426 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006436 was correctly parsed but parsing of subsequent arguments failed.
6437
Vinay Sajip35e3b032008-09-01 14:33:59 +00006438- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006439 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6440 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6441 when given a tuple of classes as second argument, were looking up
6442 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6443 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006582What's New in Python 2.6 beta 3?
6583================================
6584
Barry Warsaw07a4a382008-08-21 01:15:08 +00006585*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006586
6587Core and Builtins
6588-----------------
6589
Guido van Rossumf8402962008-08-20 15:01:50 +00006590- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6591 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6592 extensions do not automatically benefit from the class attribute
6593 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6594 to their tp_flags field if they care. This is a backwards
6595 compatibility feature; in 3.0, all types will use the cache by
6596 default.
6597
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006598- Keyword arguments can now follow starred arguments. (``f(a, *args,
6599 keyword=23)`` is now valid syntax.)
6600
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006601- ctypes function pointers that are COM methods have a boolean True
6602 value again.
6603
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006604- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6605 by denying s# to parse objects that have a releasebuffer procedure,
6606 and introducing s*.
6607
Georg Brandl1e13ea92008-08-11 09:07:59 +00006608- Issue #3537: Fix an assertion failure when an empty but presized dict
6609 object was stored in the freelist.
6610
Mark Dickinsonb6467572008-08-04 21:30:09 +00006611- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6612 ValueError consistently across platforms.
6613
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006614- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6615 (64bit Unix, for example), unichr() would truncate its argument and return
6616 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6617
Neal Norwitze7d8be82008-07-31 17:17:14 +00006618- Apply security patches from Apple.
6619
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006620- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6621 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6622
Antoine Pitrou92f82162008-07-25 22:22:08 +00006623- Issue #1819: function calls with several named parameters are now on
6624 average 35% faster (as measured by pybench).
6625
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006626- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6627 the python debugger steps into a class statement: the free variables (local
6628 variables defined in an outer scope) would be deleted from the outer scope.
6629
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006630- Issue #2620: Overflow checking when allocating or reallocating memory
6631 was not always being done properly in some python types and extension
6632 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6633 all been updated to perform better checks and places in the code that
6634 would previously leak memory on the error path when such an allocation
6635 failed have been fixed.

6638-------
6639
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006640- Issue #3612: Added some missing basic types in ctypes.wintypes.
6641
Benjamin Petersone977ad42008-08-20 01:42:01 +00006642- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6643 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6644
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006645- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6646 version reported by these tools does not necessarily follow the python
6647 version numbering scheme, so the module is less strict when parsing it.
6648
Nick Coghlanf70385a2008-08-18 12:42:46 +00006649- Issue #2235: Added Py3k warnings for types which will become unhashable
6650 under the stricter __hash__ inheritance rules in 3.0. Several types
6651 which did not meet the rules for hash invariants and were already
6652 unhashable in 3.0 have now been explicitly flagged as unhashable in
6653 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6654 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6655
Brett Cannon88f801d2008-08-18 00:46:22 +00006656- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6657 imported into the module but exposed as part of the module's API.
6658
Brett Cannon7b96f072008-08-18 00:41:11 +00006659- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6660
Brett Cannon46225e72008-08-18 00:36:52 +00006661- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
6662
Brett Cannon25c9d6a2008-08-17 22:10:11 +00006663- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6664
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006665- Issue #3575: Incremental decoder's decode function now takes bytearray
6666 by using 's*' instead of 't#'.
6667
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006668- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006669 fails unicode conversion on 2nd parameter. (windows only)
6670
Georg Brandl222e2082010-08-01 22:27:39 +00006671- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006672 in a redirect.
6673
Brett Cannonabe423e2008-08-16 21:47:07 +00006674- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006675 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006676
Facundo Batistaeb90b782008-08-16 14:44:07 +00006677- Issue #2776: fixed small issue when handling an URL with double slash
6678 after a 302 response in the case of not going through a proxy.
6679
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006680- Issue #2676: in the email package, content-type parsing was hanging on
6681 pathological input because of quadratic or exponential behaviour of a
6682 regular expression.
6683
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006684- Issue #3476: binary buffered reading through the new "io" library is now
6685 thread-safe.
6686
Brett Cannonbf3157b2008-08-14 05:00:03 +00006687- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6688 since mimetools itself is deprecated. Because modules are cached, all
6689 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6690
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006691- Issue #3134: shutil referenced undefined WindowsError symbol.
6692
Robert Schuppenies14646332008-08-10 11:01:53 +00006693- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6694 menu entries were not deleted.
6695
Brett Cannon83e81842008-08-09 23:30:55 +00006696- Copied the implementation of reduce() to _functools.reduce() to have a
6697 version that did not raise a DeprecationWarning under -3.
6698
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006699- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6700 a MemoryError rather than silently stop the iteration.
6701
Guido van Rossum59ce9012008-08-09 14:55:34 +00006702- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6703 to _sre.compile() will now be rejected. This should not affect anybody
6704 since the re.compile() function never generates invalid re-bytecode.
6705
Skip Montanaroa032bf42008-08-08 22:52:51 +00006706- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6707 upon first access it can be automatically initialized from the csv file if
6708 it wasn't initialized during instantiation.
6709
Brett Cannon3aa2a492008-08-06 22:28:09 +00006710- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6711 the reload() built-in has been removed.
6712
Brett Cannon7e30b672008-08-04 21:52:25 +00006713- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006714 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Brett Cannon7e30b672008-08-04 21:52:25 +00006720
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00006721- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
6722 raised an AttributeError.
6723
Benjamin Peterson01a24322008-07-28 23:35:27 +00006724- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00006725 asking for a specific length. This problem only affected files opened
6726 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006727
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00006728- Issue #3449: Update decimal module to use most recent specification
6729 (v. 1.68) and tests (v. 2.58) from IBM.
6730
Georg Brandl222e2082010-08-01 22:27:39 +00006731- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00006732

6735
Georg Brandlf9efabb2008-07-23 15:16:45 +00006736- Deprecate the "ast" parser function aliases.
6737
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006738- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
6739
6740- Issue #3303: Fix a crash in locale.strcoll() when calling it with
6741 invalid arguments.
6742
6743- Issue #3302: Fix several crashes when calling locale's gettext functions
6744 with None arguments.
6745
6746- Issue #3389: Allow resolving dotted names for handlers in logging
6747 configuration files.
6748
6749- Deprecate the sunaudio module for removal in Python 3.0.
6750
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006751- Issue #3394: zipfile.writestr sets external attributes when passed a
6752 file name rather than a ZipInfo instance, so files are extracted with
6753 mode 0600 rather than 000 under Unix.
6754
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006755- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6756 argument in python 2.5, this broke code that subclassed Popen to include its
6757 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00006767- Issue #2235: the C API function PyObject_HashNotImplemented and its
6768 interaction with the tp_hash slot (added in 2.6b2) are now documented
6769
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006770- Issue #643841: The language reference now provides more detailed
6771 coverage of the lookup process for special methods. The disclaimers
6772 regarding lack of coverage of new-style classes have also been
6773 removed, since the coverage is now fairly reasonable.

6782-----------------
6783
Georg Brandl3e483f62008-07-16 22:57:41 +00006784- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6785 its methods now allow for items objects that can be converted to
6786 an integer using operator.index().
6787
Mark Dickinson64b7e502008-07-16 09:40:03 +00006788- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6789 produced a ValueError instead of giving the correct float.
6790
Eric Smitha5fa5a22008-07-16 00:11:49 +00006791- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6792 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6793
Mark Dickinson7103aa42008-07-15 19:08:33 +00006794- Issue #3008: the float type has a new instance method 'float.hex'
6795 and a new class method 'float.fromhex' to convert floating-point
6796 numbers to and from hexadecimal strings, respectively.
6797
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006798- Issue #2235: __hash__ is once again inherited by default. To allow
6799 collections.Hashable to remain meaningful in the presence of the
6800 default hash implementation (object.__hash__), it is now possible
6801 to explicit block inheritance of hash by setting __hash__=None at
6802 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6803 level.
6804
Nick Coghlanb028f502008-07-13 14:52:36 +00006805- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6806 the parent module cannot be found while performing an absolute import.
6807 This means that an incorrectly defined __package__ attribute will
6808 now only prevent relative imports in that module rather than causing
6809 all imports from that module to fail.
6810
Nick Coghlan14ff9942008-07-08 14:21:42 +00006811- Issue #2517: Allow unicode messages in Exceptions again by correctly
6812 bypassing the instance dictionary when looking up __unicode__ on
6813 new-style classes.
6814
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006815- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6816 set to a custom object whose write() method happens to install
6817 another file in sys.stdout.

6821 another thread's dictionary.
6822
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006823- Issue #3004: Minor change to slice.indices(): the start and stop
6824 arguments are now treated identically, making the behaviour easier
6825 to describe and understand. For example, slice(None, -10,
6826 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6827 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6828 10, -1).
6829
Georg Brandl278fc502008-07-19 12:46:12 +00006830- Issue #3219: Calling a function with repeated keyword arguments,
6831 f(a=2, a=23), would not cause a syntax error. This was a regression
6832 from 2.4 caused by the switch to the new compiler.

7281 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007282 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007283
7284 This is controlled by the configure argument ``--with-universal-archs``:
7285
7286 - ``--with-universal-archs=all``: install 4-way universal
7287
7288 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7289
7290 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7291
7292 This option should be used in combination with ``--enable-universalsdk=``.
7293
7294 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

7331 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00007332
Christian Heimese74c8f22008-04-19 02:23:57 +00007333- Added kill, terminate and send_signal(sig) to subprocess.Popen.
7334

Georg Brandl3ee81df2008-05-17 18:14:43 +00007344- Issue #1631171: Re-implement the 'warnings' module in C (the
7345 original Python code has been kept as backup). This will allow for
7346 using the 'warning's machinery in such places as the parser where
7347 use of pure Python code is not possible. Both the ``showarning()``
7348 and ``formatwarning()`` gain an optional 'line' argument which is
7349 not called by default for backwards-compatibility reasons. Setting
7350 ``warnings.showwarning()`` to an implementation that lacks support
7351 for the ``line`` argument will raise a DeprecationWarning.

7375
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007376- The getpass module has been improved on Unix. It now uses /dev/tty
7377 by default and uses stderr instead of stdout. A GetPassWarning is
7378 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007406- Issue #2385: distutils.core.run_script() makes __file__ available,
7407 so the controlled environment will more closely mirror the typical
7408 script environment. This supports setup.py scripts that refer to
7409 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007414- Issue #2550: The approach used by client/server code for obtaining
7415 ports to listen on in network-oriented tests has been refined in an
7416 effort to facilitate running multiple instances of the entire
7417 regression test suite in parallel without issue.
7418 test_support.bind_port() has been fixed such that it will always
7419 return a unique port -- which wasn't always the case with the
7420 previous implementation, especially if socket options had been set
7421 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7422 new implementation of bind_port() will actually raise an exception
7423 if it is passed an AF_INET/SOCK_STREAM socket with either the
7424 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7425 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7426 the socket it's been passed. This currently only applies to
7427 Windows. This option prevents any other sockets from binding to the
7428 host/port we've bound to, thus removing the possibility of the
7429 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7430 when a second SOCK_STREAM socket binds and accepts to a host/port
7431 that's already been bound by another socket. The optional preferred
7432 port parameter to bind_port() has been removed. Under no
7433 circumstances should tests be hard coding ports!
7434
7435 test_support.find_unused_port() has also been introduced, which will
7436 pass a temporary socket object to bind_port() in order to obtain an
7437 unused port. The temporary socket object is then closed and
7438 deleted, and the port is returned. This method should only be used
7439 for obtaining an unused port in order to pass to an external program
7440 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7441 a parameter to a server-oriented class that doesn't give you direct
7442 access to the underlying socket used.
7443
7444 Finally, test_support.HOST has been introduced, which should be used
7445 for the host argument of any relevant socket calls (i.e. bind and
7446 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007447
7448 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007449 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007450 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7451 test_asynchat and test_socket_ssl.
7452
Georg Brandl3ee81df2008-05-17 18:14:43 +00007453 It is now possible for multiple instances of the regression test
7454 suite to run in parallel without issue.

7722
Fred Drakea8ee94b2008-03-01 02:45:07 +00007723- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007724 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00007726- Issue #2067: file.__exit__() now calls subclasses' close() method.
7727
7728- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00007729
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007730- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00007731 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00007732
Eric Smitha73fbe72008-02-23 03:09:44 +00007733- Added the future_builtins module, which contains hex() and oct().
7734 These are the PEP 3127 version of these functions, designed to be
7735 compatible with the hex() and oct() builtins from Python 3.0. They
7736 differ slightly in their output formats from the existing, unchanged
7737 Python 2.6 builtins. The expected usage of the future_builtins
7738 module is:
7739 from future_builtins import hex, oct
7740
Eric Smith7ef40bf2008-02-20 23:34:22 +00007741- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7742 exponents for exponents with absolute value < 100. Follows C99
7743 standard. This is a change on Windows, which would use 3 digits.
7744 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7745 so that any alterations it does to the resulting string will be
7746 available in stringlib/formatter.h (for float.__format__).
7747
Eric Smith5a3c1352008-02-19 13:21:56 +00007748- Implemented PEP 3101, Advanced String Formatting. This adds a new
7749 builtin format(); a format() method for str and unicode; a
7750 __format__() method to object, str, unicode, int, long, float, and
7751 datetime; the class string.Formatter; and the C API
7752 PyObject_Format().
7753
Georg Brandl3ee81df2008-05-17 18:14:43 +00007754- Fixed several potential crashes, all caused by specially crafted
7755 __del__ methods exploiting objects in temporarily inconsistent
7756 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007757
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007758- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007759 prevent a possible crash: an Abstract Base Class would try to access
7760 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007761
Georg Brandl3ee81df2008-05-17 18:14:43 +00007762- Fixed repr() and str() of complex numbers with infinity or nan as
7763 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007765- Clear all free lists during a gc.collect() of the highest generation
7766 in order to allow pymalloc to free more arenas. Python may give back
7767 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007768
Georg Brandl3ee81df2008-05-17 18:14:43 +00007769- Issue #2045: Fix an infinite recursion triggered when printing a
7770 subclass of collections.defaultdict, if its default_factory is set
7771 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007772
Christian Heimesf75dbef2008-02-08 00:11:31 +00007773- Fixed a minor memory leak in dictobject.c. The content of the free
7774 list was not freed on interpreter shutdown.
7775
Georg Brandl21e99f42010-03-07 15:23:59 +00007776- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007777 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007778
Georg Brandl3ee81df2008-05-17 18:14:43 +00007779- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7780 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007781 to compact the internal free lists of pre-allocted ints and floats.
7782
Georg Brandl3ee81df2008-05-17 18:14:43 +00007783- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7784 calls. Python expected the return type int but the fork familie
7785 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007786
Georg Brandl3ee81df2008-05-17 18:14:43 +00007787- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7788 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007799- Patch #1473257: generator objects gain a gi_code attribute. This is
7800 the same object as the func_code attribute of the function that
7801 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007802
Georg Brandl3ee81df2008-05-17 18:14:43 +00007803- Issue #1920: "while 0" statements were completely removed by the
7804 compiler, even in the presence of an "else" clause, which is
7805 supposed to be run when the condition is false. Now the compiler
7806 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007807
Guido van Rossumeead05f2008-01-24 18:21:02 +00007808- A few crashers fixed: weakref_in_del.py (issue #1377858);
7809 loosing_dict_ref.py (issue #1303614, test67.py);
7810 borrowed_ref_[34].py (not in tracker).
7811
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007812- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007813 suppressed while an extension is loaded by calling SetErrorMode in
7814 dynload_win.c. The error is still reported properly.
7815
Georg Brandl3ee81df2008-05-17 18:14:43 +00007816- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007817 several extension methods and modules do not work without unicode
7818 support.
7819
Georg Brandl26543b12008-01-21 18:36:51 +00007820- Issue #1882: when compiling code from a string, encoding cookies in the
7821 second line of code were not always recognized correctly.
7822
Georg Brandl14404b62008-01-19 19:27:05 +00007823- Issue #1679: "0x" was taken as a valid integer literal.
7824
Georg Brandl6caad7d2008-01-26 14:19:22 +00007825- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007826 added.
7827
Christian Heimesc94e2b52008-01-14 04:13:37 +00007828- sys.float_info / PyFloat_GetInfo: The floating point information
7829 object was converted from a dict to a specialized structseq object.
7830
Georg Brandl3ee81df2008-05-17 18:14:43 +00007831- Patch #1816: Added sys.flags structseq. It exposes the status of
7832 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007833
Georg Brandl3ee81df2008-05-17 18:14:43 +00007834- Objects/structseq.c: Implemented new structseq representation. The
7835 patch makes structseqs (e.g. the return value of os.stat) more
7836 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007837
Georg Brandl3ee81df2008-05-17 18:14:43 +00007838- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00007850- Improve some exception messages when Windows fails to load an
7851 extension module. Now we get for example '%1 is not a valid Win32
7852 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007860 and INF. float("nan"), float("inf") and float("-inf") now work on
7861 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007862
Georg Brandl3ee81df2008-05-17 18:14:43 +00007863- Compiler now generates simpler and faster code for dictionary
7864 literals. The oparg for BUILD_MAP now indicates an estimated
7865 dictionary size. There is a new opcode, STORE_MAP, for adding
7866 entries to the dictionary.

Neal Norwitz44f326e2007-10-05 05:29:17 +00007908- Fix warnings found by the new version of the Coverity checker.
7909
Georg Brandl21e99f42010-03-07 15:23:59 +00007910- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007911 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7912 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007913
Georg Brandl3ee81df2008-05-17 18:14:43 +00007914- Issue #1686386: Tuple's tp_repr did not take into account the
7915 possibility of having a self-referential tuple, which is possible
7916 from C code. Nor did object's tp_str consider that a type's tp_str
7917 could do something that could lead to an inifinite recursion.
7918 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7919 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007920
Georg Brandl3ee81df2008-05-17 18:14:43 +00007921- Issue #1164: It was possible to trigger deadlock when using the
7922 'print' statement to write to a file since the GIL was not released
7923 as needed. Now PyObject_Print() does the right thing along with
7924 various tp_print implementations of the built-in types and those in
7925 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007926
Georg Brandl3ee81df2008-05-17 18:14:43 +00007927- Issue #1147: Exceptions were directly allowing string exceptions in
7928 their throw() method even though string exceptions no longer
7929 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007930
Georg Brandl3ee81df2008-05-17 18:14:43 +00007931- Issue #1096: Prevent a segfault from getting the repr of a very
7932 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007933
Brett Cannon1e534b52007-09-07 04:18:30 +00007934- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007935 PyObject_Call() never calling back out to Python code to trigger
7936 recursion depth updates/checks. Required the creation of a static
7937 RuntimeError instance in case normalizing an exception put the
7938 recursion check value past its limit. Fixes crashers
7939 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007940
Georg Brandl3ee81df2008-05-17 18:14:43 +00007941- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00007954- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007955 __*__ attributes. (Some already existed, e.g., __doc__ and
7956 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007957
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007958- Add -3 option to the interpreter to warn about features that are
7959 deprecated and will be changed/removed in Python 3.0.
7960
Georg Brandl2134e752007-05-21 20:34:16 +00007961- Patch #1686487: you can now pass any mapping after '**' in function
7962 calls.
7963
Collin Winter62903052007-05-18 23:11:24 +00007964- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007965 "except E as target:". This is to provide forwards compatibility
7966 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007967
Brett Cannon229cee22007-05-05 01:34:02 +00007968- Deprecate BaseException.message as per PEP 352.
7969
Georg Brandl3ee81df2008-05-17 18:14:43 +00007970- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007971 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007972
Vinay Sajip8549ce32007-05-06 17:53:37 +00007973- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007974 setting a plain string, ie don't expand to single letter identifiers.
7975
Raymond Hettinger13936692007-04-11 18:40:58 +00007976- Request #1191699: Slices can now be pickled.
7977
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007978- Request #1193128: str.translate() now allows a None argument for
7979 translations that only remove characters without re-mapping the
7980 remaining characters.
7981
Georg Brandl5cb76c12007-03-21 09:00:39 +00007982- Patch #1682205: a TypeError while unpacking an iterable is no longer
7983 masked by a generic one with the message "unpack non-sequence".
7984
Neal Norwitzaa754b72007-03-21 06:39:48 +00007985- Remove unused file Python/fmod.c.
7986
Guido van Rossum143b5642007-03-23 04:58:42 +00007987- Bug #1683368: The object.__init__() and object.__new__() methods are
7988 now stricter in rejecting excess arguments. The only time when
7989 either allows excess arguments is when it is not overridden and the
7990 other one is. For backwards compatibility, when both are
7991 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007992 warning later). Also, type.__init__() insists on the same signature
7993 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007994
Georg Brandl3ee81df2008-05-17 18:14:43 +00007995- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7996 object to complex using its __complex__() method before falling back
7997 to the __float__() method. Therefore, the functions in the cmath
7998 module now can operate on objects that define a __complex__()
7999 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008000
Georg Brandl3ee81df2008-05-17 18:14:43 +00008001- Patch #1623563: allow __class__ assignment for classes with
8002 __slots__. The old and the new class are still required to have the
8003 same slot names.

8009 ``object.__reduce_ex__()`` is called with an object that is faking
8010 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00008011
Georg Brandl3ee81df2008-05-17 18:14:43 +00008012- Patch #1680015: Don't modify __slots__ tuple if it contains an

8016
Georg Brandl7b9c5552007-03-12 14:30:05 +00008017- Bug #1678647: write a newline after printing an exception in any
8018 case, even when converting the value to a string failed.
8019
Georg Brandl871f1bc2007-03-12 13:17:36 +00008020- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008021 its argument, if it exists. If not, it will work like before. This
8022 allows customizing the output of dir() in the presence of a
8023 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00008024
Collin Winter276887b2007-03-12 16:11:39 +00008025- Patch #922167: Python no longer segfaults when faced with infinitely
8026 self-recursive reload() calls (as reported by bug #742342).
8027

Georg Brandl3ee81df2008-05-17 18:14:43 +00008031- Patch #1491866: change the complex() constructor to allow
8032 parthensized forms. This means complex(repr(x)) now works instead of
8033 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008034
Georg Brandlaa2321b2007-03-07 00:40:28 +00008035- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008036 makes the filenames the warning module prints much more sensible
8037 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008038
Georg Brandl49aafc92007-03-07 00:34:46 +00008039- Variant of patch #697613: don't exit the interpreter on a SystemExit
8040 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00008041 variable is given, but break into the interactive interpreter just
8042 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00008050- Patch #1674228: when assigning a slice (old-style), check for the
8051 sq_ass_slice instead of the sq_slice slot.
8052
Georg Brandl3ee81df2008-05-17 18:14:43 +00008053- When printing an unraisable error, don't print exceptions. before
8054 the name. This duplicates the behavior whening normally printing
8055 exceptions.

8684 exception.

8957 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00008958
Georg Brandl3ee81df2008-05-17 18:14:43 +00008959- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8960 with RFC 3207 and forgets any knowledge obtained from the server not
8961 obtained from the TLS negotiation itself. Patch contributed by Bill
8962 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008963
Georg Brandl3ee81df2008-05-17 18:14:43 +00008964- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008965 that the SMTP.starttls() caller no longer needs to call ehlo()
8966 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008967 does not claim to support starttls. Adds the
8968 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
8969 Fenner.

9049 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9050 silently miscode subclasses of those types. Now, it raises a
9051 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009052

Georg Brandl3ee81df2008-05-17 18:14:43 +00009067 time so that opening a database previously created with the DB_DUP
9068 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9069 opens. Specifically: dictionary assignment to a DB object will
9070 replace all values for a given key when the database allows
9071 duplicate values. DB users should use DB.put(k, v) when they want
9072 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009073

9079 characters with ASCII value less than 32. Also, it correctly quotes
9080 dots only if they occur on a single line, as opposed to the previous
9081 behavior of quoting dots if they are the second character of any
9082 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009083

9379 returned by python-config if Python was built with --enable-shared
9380 because that prevented the shared library from being used.

9414-----
9415
Georg Brandl3ee81df2008-05-17 18:14:43 +00009416- Unified naming convention for free lists and their limits. All free
9417 lists in Object/ are named ``free_list``, the counter ``numfree``
9418 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
9419 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009420
Georg Brandl3ee81df2008-05-17 18:14:43 +00009421- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9422 to ``PyTuple_SetItem``, it can be used to populate a brand new
9423 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00009424
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009425- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

9428 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
9429 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009430
9431- Patch #1720595: add T_BOOL to the range of structmember types.
9432
9433- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9434 ``PyFloat_GetInfo()`` to the float API.
9435
Georg Brandl3ee81df2008-05-17 18:14:43 +00009436- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9437 of w# format code incorrectly truncated the length to an int, even
9438 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9439 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009440
Georg Brandl3ee81df2008-05-17 18:14:43 +00009441- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
9442 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009444- PEP 3123: Provide forward compatibility with Python 3.0, while
9445 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
9446 and PyVarObject_HEAD_INIT.

9458
9459- Fix some leftovers from the conversion from int to Py_ssize_t
9460 (relevant to strings and sequences of more than 2**31 items).
9461
9462- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9463 outside of pystate.c and should not be necessary.
9464
Georg Brandl3ee81df2008-05-17 18:14:43 +00009465- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9466 absolute imports. In earlier versions they might have used relative
9467 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009468
Georg Brandl3ee81df2008-05-17 18:14:43 +00009469- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9470 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009471
Georg Brandl3ee81df2008-05-17 18:14:43 +00009472- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00009479- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
9480 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
9481 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
9482 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00009483

Georg Brandl3ee81df2008-05-17 18:14:43 +00009497- Removed the macfs module. It had been deprecated since Python 2.5.
9498 This lead to the deprecation of macostools.touched() as it relied
9499 solely on macfs and was a no-op under OS X.
