343 compile() are passed buffer objects. These objects are not necessarily
344 terminated by a null byte, but the functions assumed they were.
345
Serhiy Storchaka5d7d26c2015-11-14 15:14:29 +0200346- Issue #25388: Fixed tokenizer hang when processing undecodable source code

Victor Stinnera87633e2015-10-01 09:57:26 +0200360- Issue #25003: os.urandom() doesn't use getentropy() on Solaris because

377 to check for and handle errors correctly.
378
Benjamin Peterson2c992a02015-05-28 12:45:31 -0500379- Issue #4753: On compilers where it is supported, use "computed gotos" for

421 properly to get the filename of its caller from the stack. This allows it

Terry Jan Reedya3ce2e52015-11-21 13:18:50 -0500562- Issue 15348: Stop the debugger engine (normally in a user process)
563 before closing the debugger window (running in the IDLE process).
564 This prevents the RuntimeErrors that were being caught and ignored.
565
566- Issue #24455: Prevent IDLE from hanging when a) closing the shell while the
567 debugger is active (15347); b) closing the debugger with the [X] button
568 (15348); and c) activating the debugger when already active (24455).
569 The patch by Mark Roseman does this by making two changes.
570 1. Suspend and resume the gui.interaction method with the tcl vwait
571 mechanism intended for this purpose (instead of root.mainloop & .quit).
572 2. In gui.run, allow any existing interaction to terminate first.
573
574- Change 'The program' to 'Your program' in an IDLE 'kill program?' message

Terry Jan Reedy1b6333a2015-10-04 01:14:45 -0400592- Issue #24820: IDLE now has an 'IDLE Dark' built-in text color theme.
593 It is more or less IDLE Classic inverted, with a cobalt blue background.
594 Strings, comments, keywords, ... are still green, red, orange, ... .
Terry Jan Reedya3ce2e52015-11-21 13:18:50 -0500595 To use it with IDLEs released before November 2015, hit the
596 'Save as New Custom Theme' button and enter a new name,
597 such as 'Custom Dark'. The custom theme will work with any IDLE
598 release, and can be modified.

2038
2039- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
2040 and later systems as is currently done for Python 3.x installers.
2041 For 2.7.7 only, we will provide three installers:
2042 the legacy deprecated 10.3+ 32-bit-only format;
2043 the newer 10.5+ 32-bit-only format;
2044 and the unchanged 10.6+ 64-/32-bit format.
2045 Although binary installers will no longer be available from
2046 python.org as of 2.7.8, it will still be possible to build from
2047 source on 10.3.9 and 10.4 systems if necessary.
2048 See Mac/BuildScript/README.txt for more information.

3430 32-bit-only installer Pythons on systems with Xcode 4 (currently
3431 OS X 10.8, 10.7, and optionally 10.6).
3432 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
3433 * Since Xcode 4 removes ppc support, extension module builds now
3434 check for ppc compiler support and by default remove ppc and
3435 ppc64 archs when they are not available.
3436 * Extension module builds now revert to using system installed
3437 headers and libs (/usr and /System/Library) if the SDK used
3438 to build the interpreter is not installed or has moved.
3439 * Try to avoid building extension modules with deprecated
3440 and problematic Apple llvm-gcc compiler. If original compiler
3441 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01003878- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01003879 has left two versions of customize_compiler, the original in
3880 distutils.sysconfig and another copy in distutils.ccompiler, with some
3881 parts of distutils calling one and others using the other.
3882 Complete the revert back to only having one in distutils.sysconfig as
3883 is the case in 3.x.
3884
Ned Deily0d0ea482012-02-10 12:59:06 +01003885- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
3886 Distutils-based packages with C extension modules may fail because
3887 Apple has removed gcc-4.2, the version used to build python.org
3888 64-bit/32-bit Pythons. If the user does not explicitly override
3889 the default C compiler by setting the CC environment variable,
3890 Distutils will now attempt to compile extension modules with clang
3891 if gcc-4.2 is required but not found. Also as a convenience, if
3892 the user does explicitly set CC, substitute its value as the default
3893 compiler in the Distutils LDSHARED configuration variable for OS X.
3894 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
3895 SDK, neither of which are available in Xcode 4. This change does not
3896 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07004146- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
4147 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
4148 interpreter process. This could cause failures in non-Distutils subprocesses
4149 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02004150 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07004151 deployment target only in the environment of each build subprocess. It is
4152 still possible to globally override the default by setting
4153 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
4154 greater or equal to the default value, the value with which the interpreter
4155 was built.

4185 the ticker doesn't have to wind down to zero from the old starting point
4186 before the new interval takes effect. And if the user increases the
4187 interval, it makes sure the new limit takes effect right away rather have an
4188 early task switch before recognizing the new interval.

5038 thread-local storage key.
5039
Victor Stinnercaafd772010-09-08 10:51:01 +00005040- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
5041 encoding and errors attributes instead of using utf-8 in strict mode, to get
5042 the same behaviour than the print statement.
5043
Antoine Pitrou9cf85f12010-09-01 21:17:34 +00005044- Issue #9737: Fix a crash when trying to delete a slice or an item from

5057 output with no type specifier failed to match the str output:
5058
5059 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
5060 - format(complex(0.0, 2.0), '-') included a sign and parentheses.
5061
Antoine Pitrou32669782010-07-11 12:14:05 +00005062- Issue #7616: Fix copying of overlapping memoryview slices with the Intel

5153 with invalid characters after '=' in a Q-encoded word.
5154

5156 received. Now sendall() properly calls signal handlers if necessary,

5169 handles non-blocking readinto() returning None correctly.

5172 SSLSocket.sendto() to match the corresponding socket methods. Also,
5173 fix various SSLSocket methods to raise socket.error rather than an
5174 unhelpful TypeError when called on an unconnected socket. Original patch
5175 by Andrew Bennetts.
5176
Raymond Hettinger74f869e2010-09-13 22:14:36 +00005177- Issue #9826: OrderedDict.__repr__ can now handle self-referential
5178 values: d['x'] = d.
5179
Victor Stinner8fc843b2010-09-17 23:35:50 +00005180- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X.

5184
Raymond Hettinger20397532010-09-12 02:11:45 +00005185- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
5186 This prevents user-created self-referencing ordered dictionaries from
5187 becoming permanently uncollectable GC garbage. The downside is that
5188 removing __del__ means that the internal doubly-linked list has to wait for
5189 GC collection rather than freeing memory immediately when the refcnt drops
5190 to zero.
5191
Raymond Hettingerffd2a422010-09-10 10:47:22 +00005192- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +00005193 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +00005194 value.
5195
Antoine Pitrouc818ed42010-09-07 21:40:25 +00005196- Issue #9792: In case of connection failure, socket.create_connection()
5197 would swallow the exception and raise a new one, making it impossible
5198 to fetch the original errno, or to filter timeout errors. Now the
5199 original error is re-raised.
5200
Antoine Pitrouf4f61712010-09-07 16:34:47 +00005201- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
5202 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
5203 be updated back after the system call. Original patch by Brian Brazil.
5204
Antoine Pitroudca9de92010-09-04 17:52:26 +00005205- Issue #1100562: Fix deep-copying of objects derived from the list and

5209 ConfigParser.write.
5210
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00005211- Issue #808164: Fixed socket.close to avoid references to globals, to
5212 avoid issues when socket.close is called from a __del__ method.
5213
Terry Reedyd2d2ae92010-11-11 23:22:19 +00005214- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which
5215 can be set to False to turn off the previously undocumented 'popularity'
5216 heuristic. Patch by Terry Reedy and Eli Bendersky
5217
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00005218- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
5219 falling into recursion.
5220
R. David Murray7c4bf552010-08-25 01:45:57 +00005221- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
5222 character years even if the message contains RFC822 two character years.
5223
Daniel Stutzbach91287322010-08-24 21:09:30 +00005224- Issue #8750: Fixed MutableSet's methods to correctly handle

5234
Raymond Hettinger917bba12010-08-22 08:01:58 +00005235- Issue #9214: Set operations on KeysView or ItemsView in the collections
5236 module now correctly return a set. (Patch by Eli Bendersky.)
5237
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00005238- Issue #9617: Signals received during a low-level write operation aren't
5239 ignored by the buffered IO layer anymore.
5240
Benjamin Peterson52c36052010-08-21 03:03:22 +00005241- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
5242 are not held onto after they are deleted elsewhere.
5243
Raymond Hettingera54b2da2010-08-17 19:03:06 +00005244- Issue #9626: the view methods for collections.OrderedDict() were returning
5245 the unordered versions inherited from dict. Those methods are now
5246 overridden to provide ordered views.
5247

5249 comment indicating they are generated. Manually maintained MANIFESTs
5250 without this marker will not be overwritten or removed.
5251
Antoine Pitroue1436d12010-08-12 15:25:51 +00005252- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
5253 and a BadZipfile error is raised if it doesn't match (as used to be the
5254 case in Python 2.5 and earlier).
5255
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00005256- Issue #9550: a BufferedReader could issue an additional read when the
5257 original read request had been satisfied, which could block indefinitely
5258 when the underlying raw IO channel was e.g. a socket. Report and original
5259 patch by Jason V. Miller.
5260
Fred Drake0a1fa0e2010-08-10 13:09:54 +00005261- Issue #9551: Don't raise TypeError when setting the value to None for

Senthil Kumarane677ecf2010-08-08 11:56:31 +00005279- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
5280 This is how it is supposed to work, wget and curl do the same. Previous
5281 behavior was wrong.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00005648- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
5649 start byte and the continuation byte(s) are now considered invalid, instead
5650 of the number of bytes specified by the start byte.
5651 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
5652 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
5653 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
5654 Previous versions returned a single u'\ufffd'.

5663 objects. (1) The comparison could incorrectly return True in some cases
5664 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
5665 (2) The comparison raised an OverflowError for large integers, leading

5861 operation raises multiple signals and more than one of those signals is
5862 trapped, the specification determines the order in which the signals should be

6050 with a non-empty format string. This is an effort to future-proof user
6051 code. If a derived class does not currently implement __format__ but later
6052 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00006053 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00006054 Python 3.3 and it will be an error in Python 3.4.

6105 InvalidOperation instead of returning False. (Comparisons involving a quiet
6106 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
6107 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00006109- Issue #2531: Comparison operations between floats and Decimal instances now
6110 return a result based on the numeric values of the operands; previously they
6111 returned an arbitrary result based on the relative ordering of id(float) and
6112 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00006115 argument `-` which tells it to read files to compile from stdin. Each line is
6116 read on demand and the named file is compiled immediately. (Original patch by
6117 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00006126- Comparisons using one of <, <=, >, >= between a complex instance and a
6127 Fractions instance now raise TypeError instead of returning True/False. This
6128 makes Fraction <=> complex comparisons consistent with int <=> complex, float
6129 <=> complex, and complex <=> complex comparisons.

6229 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00006233- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
6234 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
6235 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00006236 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
6237 inconsistent: __int__ was used for some integer codes but not for others, and
6238 the set of integer codes for which it was used differed between native packing
6239 and standard packing.)

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00006546- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00006547 file position when calling `truncate()`. It would previously change the file
6548 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00006549 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Georg Brandlba83f822010-03-14 09:50:54 +00006551- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
6552 class used to represent files stored inside an archive. The new
6553 implementation is significantly faster and can be wrapped in a
6554 ``io.BufferedReader`` object for more speedups. It also solves an issue
6555 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

6645
Georg Brandlba83f822010-03-14 09:50:54 +00006646- The ``__complex__()`` method is now looked up on the class of instances to
6647 make it consistent with other special methods.

6651
Mark Dickinson1b34d252010-01-01 17:27:30 +00006652- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00006653 DeprecationWarning when passed a float argument where an integer was expected.
6654 These functions and methods now raise TypeError instead. The majority of the
6655 effects of this change are in the extension modules, but some core functions
6656 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
6657 and many unicode/str methods.

6671 of integers: the result of a/b is now correctly rounded for ints a and b (at
6672 least on IEEE 754 platforms), and in particular does not depend on the
6673 internal representation of a long.

6681
Georg Brandlba83f822010-03-14 09:50:54 +00006682 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00006821- Issue #3382: 'F' formatting for float and complex now convert the result to
6822 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
6823 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00006824
Georg Brandlba83f822010-03-14 09:50:54 +00006825- Remove switch from "%f" formatting to "%g" formatting for floats larger than
6826 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00006827
Georg Brandlba83f822010-03-14 09:50:54 +00006828- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
6829 1e-100 used to raise OverflowError, but now gives the requested 120
6830 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00006838
Georg Brandlba83f822010-03-14 09:50:54 +00006839- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
6840 decimal string that's guaranteed to round back to x under correct rounding
6841 (with round-half-to-even rounding mode). Previously it gave a string based on
6842 rounding x to 17 decimal digits. repr(x) for a complex number behaves
6843 similarly. On platforms where the correctly-rounded strtod and dtoa code is
6844 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006845
Georg Brandlba83f822010-03-14 09:50:54 +00006846- Issue #7117: On almost all platforms: float-to-string and string-to-float
6847 conversions within Python are now correctly rounded. Places these conversions
6848 occur include: str for floats and complex numbers; the float and complex
6849 constructors; old-style and new-style numeric formatting; serialization and
6850 deserialization of floats and complex numbers using marshal, pickle and json;
6851 parsing of float and imaginary literals in Python code; Decimal-to-float
6852 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006853
Georg Brandlba83f822010-03-14 09:50:54 +00006854 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
6855 providing correctly-rounded strtod and dtoa C functions. This code is
6856 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
6857 the C compiler. There may be a small number of platforms on which correct
6858 operation of this code cannot be guaranteed, so the code is not used: notably,
6859 this applies to platforms where the C double format is not IEEE 754 binary64,
6860 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
6861 and Python's configure script is unable to determine how to change the FPU
6862 precision. On these platforms conversions use the platform strtod and dtoa,
6863 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006864
Georg Brandlba83f822010-03-14 09:50:54 +00006865- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
6866 uses the correctly-rounded string <-> float conversions described above (when
6867 available), and so produces correctly rounded results that will display nicely
6868 under the float repr. There are two related small changes: (1) round now
6869 accepts any class with an ``__index__()`` method for its second argument (but
6870 no longer accepts floats for the second argument), and (2) an excessively
6871 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
6872 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00007013- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00007014
Georg Brandlba83f822010-03-14 09:50:54 +00007015 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
7016 (2) parsing of strings representing infinities and nans was locale aware; and
7017 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00007019- Issue #5920: For ``float.__format__()``, change the behavior with the empty
7020 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
7021 but with at least one decimal point and with a default precision
7022 of 12. Previously, the behavior the same but with a default precision of 6.
7023 This more closely matches ``str()``, and reduces surprises when adding
7024 alignment flags to the empty presentation type. This also affects the new
7025 complex.__format__ in the same way.
7026
7027- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
7028 classtype's, even if it was None. property now inserts the __doc__ into the
7029 subclass instance __dict__.

Georg Brandlba83f822010-03-14 09:50:54 +00007090 untrackable objects are not tracked by the garbage collector. This can reduce
7091 the size of collections and therefore the garbage collection overhead on

7099 internal representation of integers, for performance reasons. Base 2**30 is
7100 enabled by default on 64-bit machines. Add --enable-big-digits option to
7101 configure, which overrides the default. Add sys.long_info structseq to
7102 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00007249- On windows, ``os.chdir()`` given unicode was not working if

7251 this code path is really executed because I cannot move to such directory on
7252 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00007254- Issue #4069: When ``set.remove(element)`` is used with a set element, the
7255 element is temporarily replaced with an equivalent frozenset. But the
7256 eventual KeyError would always report the empty ``frozenset()`` as the missing
7257 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00007277- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
7278 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
7279 step. This avoids problems with counting UTF-8 bytes that ignores the effect
7280 of using the replace error handler in PyUnicode_DecodeUTF8().

Walter Dörwald726ba8e2009-05-06 14:32:35 +00007282- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00007285- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

7287 gives improved memory leak detection when running under Valgrind, while taking
7288 advantage of pymalloc at other times.

8479 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
8480 neither __int__ nor __long__, TypeError used to be raised (with a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00008677- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
8678
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00008679- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
8680 PyString_FromFormat or PyErr_Format to display size_t values. The macro
8681 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
8682 ``printf`` function, whereas PyString_FromFormat has an independent
8683 implementation and uses "%zd" on all platforms for size_t values.
8684 This makes a difference on win64, where ``printf`` needs "%Id" to display
8685 64bit values.
8686
Benjamin Peterson97179b02008-09-09 20:55:01 +00008687- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00008690- Issue #3777: long() applied to a float object now always return a long
8691 object; previously an int would be returned for small values. the __long__
8692 method is allowed to return either an int or a long, but the behaviour of
8693 float objects should not change to respect backward compatibility.
8694
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00008695- Issue #3751: str.rpartition would perform a left-partition when called with
8696 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00008701 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00008702 was correctly parsed but parsing of subsequent arguments failed.
8703
Vinay Sajip35e3b032008-09-01 14:33:59 +00008704- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00008705 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
8706 mechanism. In the process, fix a bug where isinstance() and issubclass(),
8707 when given a tuple of classes as second argument, were looking up
8708 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
8709 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00008780 warnings.catch_warnings() along with some API cleanup. Expanding the tests
8781 for catch_warnings() also led to an improvement in the raising of a

8854-----------------
8855
Guido van Rossumf8402962008-08-20 15:01:50 +00008856- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
8857 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
8858 extensions do not automatically benefit from the class attribute
8859 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
8860 to their tp_flags field if they care. This is a backwards
8861 compatibility feature; in 3.0, all types will use the cache by
8862 default.
8863
Benjamin Petersonf647dc12008-08-20 01:27:30 +00008864- Keyword arguments can now follow starred arguments. (``f(a, *args,
8865 keyword=23)`` is now valid syntax.)
8866
Thomas Heller0ad5ae02008-08-19 19:25:04 +00008867- ctypes function pointers that are COM methods have a boolean True
8868 value again.
8869
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00008870- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
8871 by denying s# to parse objects that have a releasebuffer procedure,
8872 and introducing s*.
8873
Georg Brandl1e13ea92008-08-11 09:07:59 +00008874- Issue #3537: Fix an assertion failure when an empty but presized dict
8875 object was stored in the freelist.
8876
Mark Dickinsonb6467572008-08-04 21:30:09 +00008877- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
8878 ValueError consistently across platforms.
8879
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00008880- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
8881 (64bit Unix, for example), unichr() would truncate its argument and return
8882 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
8883
Neal Norwitze7d8be82008-07-31 17:17:14 +00008884- Apply security patches from Apple.
8885
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00008886- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
8887 PyErr_ExceptionMatches returns 0 when an exception occurs there.
8888
Antoine Pitrou92f82162008-07-25 22:22:08 +00008889- Issue #1819: function calls with several named parameters are now on
8890 average 35% faster (as measured by pybench).
8891
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00008892- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
8893 the python debugger steps into a class statement: the free variables (local
8894 variables defined in an outer scope) would be deleted from the outer scope.
8895
Gregory P. Smith0470bab2008-07-22 04:46:32 +00008896- Issue #2620: Overflow checking when allocating or reallocating memory
8897 was not always being done properly in some python types and extension
8898 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
8899 all been updated to perform better checks and places in the code that
8900 would previously leak memory on the error path when such an allocation
8901 failed have been fixed.

8907
Benjamin Petersone977ad42008-08-20 01:42:01 +00008908- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
8909 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
8910
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00008911- Issue #2234: distutils failed for some versions of the cygwin compiler. The
8912 version reported by these tools does not necessarily follow the python
8913 version numbering scheme, so the module is less strict when parsing it.
8914
Nick Coghlanf70385a2008-08-18 12:42:46 +00008915- Issue #2235: Added Py3k warnings for types which will become unhashable
8916 under the stricter __hash__ inheritance rules in 3.0. Several types
8917 which did not meet the rules for hash invariants and were already
8918 unhashable in 3.0 have now been explicitly flagged as unhashable in
8919 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
8920 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)

Antoine Pitroude781a42008-08-09 12:43:23 +00008991 asking for a specific length. This problem only affected files opened

9034 interaction with the tp_hash slot (added in 2.6b2) are now documented
9035
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00009036- Issue #643841: The language reference now provides more detailed

9043================================
9044
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00009045*Release date: 17-Jul-2008*
9046
Raymond Hettingere3ae6552008-06-20 04:18:15 +00009047Core and Builtins
9048-----------------
9049
Georg Brandl3e483f62008-07-16 22:57:41 +00009050- Issue #3156: Fix inconsistent behavior of the bytearray type: all
9051 its methods now allow for items objects that can be converted to
9052 an integer using operator.index().
9053
Mark Dickinson64b7e502008-07-16 09:40:03 +00009054- Issue #3360: Fix incorrect parsing of '020000000000.0', which
9055 produced a ValueError instead of giving the correct float.
9056
Eric Smitha5fa5a22008-07-16 00:11:49 +00009057- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
9058 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
9059
Mark Dickinson7103aa42008-07-15 19:08:33 +00009060- Issue #3008: the float type has a new instance method 'float.hex'
9061 and a new class method 'float.fromhex' to convert floating-point
9062 numbers to and from hexadecimal strings, respectively.
9063
Nick Coghlan6d6bd442008-07-15 15:40:22 +00009064- Issue #2235: __hash__ is once again inherited by default. To allow
9065 collections.Hashable to remain meaningful in the presence of the
9066 default hash implementation (object.__hash__), it is now possible
9067 to explicit block inheritance of hash by setting __hash__=None at
9068 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
9069 level.
9070
Nick Coghlanb028f502008-07-13 14:52:36 +00009071- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
9072 the parent module cannot be found while performing an absolute import.
9073 This means that an incorrectly defined __package__ attribute will
9074 now only prevent relative imports in that module rather than causing
9075 all imports from that module to fail.
9076
Nick Coghlan14ff9942008-07-08 14:21:42 +00009077- Issue #2517: Allow unicode messages in Exceptions again by correctly
9078 bypassing the instance dictionary when looking up __unicode__ on
9079 new-style classes.
9080
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00009081- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
9082 set to a custom object whose write() method happens to install
9083 another file in sys.stdout.
9084
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00009085- Issue #3088: Corrected a race condition in classes derived from
9086 threading.local: the first member set by a thread could be saved in
9087 another thread's dictionary.
9088
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00009089- Issue #3004: Minor change to slice.indices(): the start and stop
9090 arguments are now treated identically, making the behaviour easier
9091 to describe and understand. For example, slice(None, -10,
9092 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
9093 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
9094 10, -1).
9095
Georg Brandl278fc502008-07-19 12:46:12 +00009096- Issue #3219: Calling a function with repeated keyword arguments,
9097 f(a=2, a=23), would not cause a syntax error. This was a regression
9098 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00009099
Georg Brandl278fc502008-07-19 12:46:12 +00009100- Issue #2862: Make int and float freelist management consistent with
9101 other freelists. Changes their CompactFreeList apis into
9102 ClearFreeList apis and calls them via gc.collect().

9108 api functions without holding the GIL, which could lead to a fatal
9109 error when they failed.
9110
Martin v. Löwisaabf4042008-08-02 07:20:25 +00009111- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00009136- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
9137 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00009138 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00009139 content-length. The problem had been corrected in the 2.4 branch, but never
9140 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00009155- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Ronald Oussoren5640ce22008-06-05 12:58:24 +00009544- On MacOS X it is now possible to install the framework in 64-bit
9545 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00009546 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00009547
9548 This is controlled by the configure argument ``--with-universal-archs``:
9549
9550 - ``--with-universal-archs=all``: install 4-way universal
9551
9552 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
9553
9554 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
9555
9556 This option should be used in combination with ``--enable-universalsdk=``.
9557
9558 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 +00009607- Issue #1631171: Re-implement the 'warnings' module in C (the
9608 original Python code has been kept as backup). This will allow for
9609 using the 'warning's machinery in such places as the parser where
9610 use of pure Python code is not possible. Both the ``showarning()``
9611 and ``formatwarning()`` gain an optional 'line' argument which is
9612 not called by default for backwards-compatibility reasons. Setting
9613 ``warnings.showwarning()`` to an implementation that lacks support
9614 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009677- Issue #2550: The approach used by client/server code for obtaining
9678 ports to listen on in network-oriented tests has been refined in an
9679 effort to facilitate running multiple instances of the entire
9680 regression test suite in parallel without issue.
9681 test_support.bind_port() has been fixed such that it will always
9682 return a unique port -- which wasn't always the case with the
9683 previous implementation, especially if socket options had been set
9684 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
9685 new implementation of bind_port() will actually raise an exception
9686 if it is passed an AF_INET/SOCK_STREAM socket with either the
9687 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
9688 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
9689 the socket it's been passed. This currently only applies to
9690 Windows. This option prevents any other sockets from binding to the
9691 host/port we've bound to, thus removing the possibility of the
9692 'non-deterministic' behaviour, as Microsoft puts it, that occurs
9693 when a second SOCK_STREAM socket binds and accepts to a host/port
9694 that's already been bound by another socket. The optional preferred
9695 port parameter to bind_port() has been removed. Under no
9696 circumstances should tests be hard coding ports!
9697
9698 test_support.find_unused_port() has also been introduced, which will
9699 pass a temporary socket object to bind_port() in order to obtain an
9700 unused port. The temporary socket object is then closed and
9701 deleted, and the port is returned. This method should only be used
9702 for obtaining an unused port in order to pass to an external program
9703 (i.e. the -accept [port] argument to openssl's s_server mode) or as
9704 a parameter to a server-oriented class that doesn't give you direct
9705 access to the underlying socket used.
9706
9707 Finally, test_support.HOST has been introduced, which should be used
9708 for the host argument of any relevant socket calls (i.e. bind and
9709 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00009710
9711 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00009712 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00009713 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
9714 test_asynchat and test_socket_ssl.
9715
Georg Brandl3ee81df2008-05-17 18:14:43 +00009716 It is now possible for multiple instances of the regression test
9717 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00009771- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00009772 \Uxxxxxxxx did not accept values outside the Basic Multilingual
9773 Plane. This affected raw unicode literals and the
9774 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
9775 this case, like normal unicode literals and the 'unicode-escape'
9776 codec.

9999 differ slightly in their output formats from the existing, unchanged
10000 Python 2.6 builtins. The expected usage of the future_builtins
10001 module is:
10002 from future_builtins import hex, oct
10003
Eric Smith7ef40bf2008-02-20 23:34:22 +000010004- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
10005 exponents for exponents with absolute value < 100. Follows C99
10006 standard. This is a change on Windows, which would use 3 digits.
10007 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
10008 so that any alterations it does to the resulting string will be
10009 available in stringlib/formatter.h (for float.__format__).
10010
Eric Smith5a3c1352008-02-19 13:21:56 +000010011- Implemented PEP 3101, Advanced String Formatting. This adds a new
10012 builtin format(); a format() method for str and unicode; a
10013 __format__() method to object, str, unicode, int, long, float, and
10014 datetime; the class string.Formatter; and the C API
10015 PyObject_Format().
10016
Georg Brandl3ee81df2008-05-17 18:14:43 +000010017- Fixed several potential crashes, all caused by specially crafted
10018 __del__ methods exploiting objects in temporarily inconsistent
10019 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +000010020
Vinay Sajipb7edfc42008-04-02 21:10:23 +000010021- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +000010022 prevent a possible crash: an Abstract Base Class would try to access
10023 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +000010024

Georg Brandl3ee81df2008-05-17 18:14:43 +000010028- Clear all free lists during a gc.collect() of the highest generation
10029 in order to allow pymalloc to free more arenas. Python may give back
10030 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +000010031
Georg Brandl3ee81df2008-05-17 18:14:43 +000010032- Issue #2045: Fix an infinite recursion triggered when printing a
10033 subclass of collections.defaultdict, if its default_factory is set
10034 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +000010035
Christian Heimesf75dbef2008-02-08 00:11:31 +000010036- Fixed a minor memory leak in dictobject.c. The content of the free
10037 list was not freed on interpreter shutdown.
10038
Georg Brandl21e99f42010-03-07 15:23:59 +000010039- Limit free list of method and built-in function objects to 256

Georg Brandl3ee81df2008-05-17 18:14:43 +000010062- Patch #1473257: generator objects gain a gi_code attribute. This is
10063 the same object as the func_code attribute of the function that
10064 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +000010065
Georg Brandl3ee81df2008-05-17 18:14:43 +000010066- Issue #1920: "while 0" statements were completely removed by the
10067 compiler, even in the presence of an "else" clause, which is
10068 supposed to be run when the condition is false. Now the compiler
10069 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +000010070

10074
Vinay Sajipd7cf32e2008-01-24 12:43:33 +000010075- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +000010076 suppressed while an extension is loaded by calling SetErrorMode in
10077 dynload_win.c. The error is still reported properly.
10078
Georg Brandl3ee81df2008-05-17 18:14:43 +000010079- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +000010080 several extension methods and modules do not work without unicode
10081 support.
10082
Georg Brandl26543b12008-01-21 18:36:51 +000010083- Issue #1882: when compiling code from a string, encoding cookies in the

10085
Georg Brandl14404b62008-01-19 19:27:05 +000010086- Issue #1679: "0x" was taken as a valid integer literal.
10087
Georg Brandl6caad7d2008-01-26 14:19:22 +000010088- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +000010089 added.
10090
Christian Heimesc94e2b52008-01-14 04:13:37 +000010091- sys.float_info / PyFloat_GetInfo: The floating point information
10092 object was converted from a dict to a specialized structseq object.
10093
Georg Brandl3ee81df2008-05-17 18:14:43 +000010094- Patch #1816: Added sys.flags structseq. It exposes the status of
10095 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +000010096
Georg Brandl3ee81df2008-05-17 18:14:43 +000010097- Objects/structseq.c: Implemented new structseq representation. The
10098 patch makes structseqs (e.g. the return value of os.stat) more
10099 readable.
Christian Heimes9c201962008-01-14 03:33:52 +000010100
Georg Brandl3ee81df2008-05-17 18:14:43 +000010101- Patch #1700288: added a type attribute cache that caches method
10102 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +000010103
Neal Norwitz3fc15b82008-01-10 05:42:58 +000010104- Bug #1776: __import__() no longer accepts filenames on any platform.

10108
Georg Brandl3ee81df2008-05-17 18:14:43 +000010109- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
10110 envvar and sys.dont_write_bytecode attribute. All these can be set
10111 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +000010112
Georg Brandl3ee81df2008-05-17 18:14:43 +000010113- Improve some exception messages when Windows fails to load an
10114 extension module. Now we get for example '%1 is not a valid Win32
10115 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +000010116

Christian Heimes0a8143f2007-12-18 23:22:54 +000010122- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +000010123 and INF. float("nan"), float("inf") and float("-inf") now work on
10124 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +000010125
Georg Brandl3ee81df2008-05-17 18:14:43 +000010126- Compiler now generates simpler and faster code for dictionary
10127 literals. The oparg for BUILD_MAP now indicates an estimated
10128 dictionary size. There is a new opcode, STORE_MAP, for adding
10129 entries to the dictionary.

10164 function uses a generator expression when at the same time the
10165 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +000010166
Raymond Hettinger1760c8a2007-11-08 02:52:43 +000010167- sets and frozensets now have an isdisjoint() method.

10172
Georg Brandl21e99f42010-03-07 15:23:59 +000010173- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +000010174 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
10175 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +000010176
Georg Brandl3ee81df2008-05-17 18:14:43 +000010177- Issue #1686386: Tuple's tp_repr did not take into account the
10178 possibility of having a self-referential tuple, which is possible
10179 from C code. Nor did object's tp_str consider that a type's tp_str
10180 could do something that could lead to an inifinite recursion.
10181 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
10182 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +000010183
Georg Brandl3ee81df2008-05-17 18:14:43 +000010184- Issue #1164: It was possible to trigger deadlock when using the
10185 'print' statement to write to a file since the GIL was not released
10186 as needed. Now PyObject_Print() does the right thing along with
10187 various tp_print implementations of the built-in types and those in
10188 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +000010189
Georg Brandl3ee81df2008-05-17 18:14:43 +000010190- Issue #1147: Exceptions were directly allowing string exceptions in

Georg Brandl3ee81df2008-05-17 18:14:43 +000010198 PyObject_Call() never calling back out to Python code to trigger
10199 recursion depth updates/checks. Required the creation of a static
10200 RuntimeError instance in case normalizing an exception put the
10201 recursion check value past its limit. Fixes crashers
10202 infinite_rec_(1|2|4|5).py.

10225 calls.
10226
Collin Winter62903052007-05-18 23:11:24 +000010227- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +000010228 "except E as target:". This is to provide forwards compatibility
10229 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010233- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +000010234 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +000010235
Vinay Sajip8549ce32007-05-06 17:53:37 +000010236- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +000010237 setting a plain string, ie don't expand to single letter identifiers.

Serhiy Storchaka16870742015-08-09 13:07:06 +030010241- Request #1193128: str.translate() now allows a None argument for
Raymond Hettinger4db5fe92007-04-12 04:10:00 +000010242 translations that only remove characters without re-mapping the
10243 remaining characters.
10244
Georg Brandl5cb76c12007-03-21 09:00:39 +000010245- Patch #1682205: a TypeError while unpacking an iterable is no longer
10246 masked by a generic one with the message "unpack non-sequence".
10247

10249
Guido van Rossum143b5642007-03-23 04:58:42 +000010250- Bug #1683368: The object.__init__() and object.__new__() methods are
10251 now stricter in rejecting excess arguments. The only time when
10252 either allows excess arguments is when it is not overridden and the
10253 other one is. For backwards compatibility, when both are
10254 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +000010255 warning later). Also, type.__init__() insists on the same signature
10256 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +000010258- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
10259 object to complex using its __complex__() method before falling back
10260 to the __float__() method. Therefore, the functions in the cmath
10261 module now can operate on objects that define a __complex__()
10262 method.

10282
Georg Brandl871f1bc2007-03-12 13:17:36 +000010283- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +000010284 its argument, if it exists. If not, it will work like before. This
10285 allows customizing the output of dir() in the presence of a
10286 __getattr__().

10295 parthensized forms. This means complex(repr(x)) now works instead of
10296 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +000010297
Georg Brandlaa2321b2007-03-07 00:40:28 +000010298- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +000010299 makes the filenames the warning module prints much more sensible
10300 when a PYTHONSTARTUP file is used.

10311 condition.
Georg Brandl098cd692007-03-06 12:17:50 +000010312
Georg Brandl0fca97a2007-03-05 22:28:08 +000010313- Patch #1674228: when assigning a slice (old-style), check for the

10315
Georg Brandl3ee81df2008-05-17 18:14:43 +000010316- When printing an unraisable error, don't print exceptions. before

10327 created a weakref on itself during a __del__ call for new-style
10328 classes (classic classes still have the bug).

Georg Brandl2c1375c2006-10-12 11:27:59 +000010368- Bug #1545497: when given an explicit base, int() did ignore NULs
10369 embedded in the string to convert.
10370
Georg Brandl846f73a2006-10-08 07:11:54 +000010371- Bug #1569998: break inside a try statement (outside a loop) is now

Armin Rigo7ccbca92006-10-04 12:17:45 +000010376- A number of places, including integer negation and absolute value,
10377 were fixed to not rely on undefined behaviour of the C compiler
10378 anymore.

Georg Brandl4e933132006-09-06 20:05:58 +000010401- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010419 generator expressions (x for x, in ... ) works again. Fixing this
10420 problem required changing the .pyc magic number. This means that
10421 .pyc files generated before 2.5c2 will be regenerated.

Martin v. Löwis05c075d2007-03-07 11:04:33 +000010939- Bug #1115886: os.path.splitext('.cshrc') gives now ('.cshrc', '').
10940
Georg Brandl3ee81df2008-05-17 18:14:43 +000010941- unittest now verifies more of its assumptions. In particular,
10942 TestCase and TestSuite subclasses (not instances) are no longer
10943 accepted in TestSuite.addTest(). This should cause no
10944 incompatibility since it never made sense with ordinary subclasses
10945 -- the failure just occurred later, with a more cumbersome
10946 exception.

11215 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +000011216
Georg Brandl3ee81df2008-05-17 18:14:43 +000011217- The implementation of UnicodeError objects has been simplified

Georg Brandl3ee81df2008-05-17 18:14:43 +000011226- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +000011227 that the SMTP.starttls() caller no longer needs to call ehlo()
11228 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +000011229 does not claim to support starttls. Adds the
11230 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +000011273- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +000011274 works as expected. ``mmap.find`` also takes an optional ``end``

11311 complex, tuple, list, dict, set, and frozenset. Formerly, it would
11312 silently miscode subclasses of those types. Now, it raises a
11313 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +000011314

Georg Brandl3ee81df2008-05-17 18:14:43 +000011329 time so that opening a database previously created with the DB_DUP
11330 or DB_DUPSORT flag set will keep the proper behavior on subsequent
11331 opens. Specifically: dictionary assignment to a DB object will
11332 replace all values for a given key when the database allows
11333 duplicate values. DB users should use DB.put(k, v) when they want
11334 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +000011335

11341 characters with ASCII value less than 32. Also, it correctly quotes
11342 dots only if they occur on a single line, as opposed to the previous
11343 behavior of quoting dots if they are the second character of any
11344 line.
Georg Brandl4aef7272007-03-13 22:49:43 +000011345

Neal Norwitz92422fb2006-08-18 03:57:54 +000011671C API
11672-----
11673
Georg Brandl3ee81df2008-05-17 18:14:43 +000011674- Unified naming convention for free lists and their limits. All free
11675 lists in Object/ are named ``free_list``, the counter ``numfree``
11676 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
11677 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +000011678
Georg Brandl3ee81df2008-05-17 18:14:43 +000011679- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
11680 to ``PyTuple_SetItem``, it can be used to populate a brand new
11681 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +000011682
Vinay Sajipb7edfc42008-04-02 21:10:23 +000011683- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +000011685- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
11686 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
11687 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +000011688
11689- Patch #1720595: add T_BOOL to the range of structmember types.
11690
11691- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
11692 ``PyFloat_GetInfo()`` to the float API.
11693
Georg Brandl3ee81df2008-05-17 18:14:43 +000011694- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
11695 of w# format code incorrectly truncated the length to an int, even
11696 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
11697 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +000011698
Georg Brandl3ee81df2008-05-17 18:14:43 +000011699- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
11700 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000011701
Georg Brandl3ee81df2008-05-17 18:14:43 +000011702- PEP 3123: Provide forward compatibility with Python 3.0, while
11703 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
11704 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000011705
Georg Brandl3ee81df2008-05-17 18:14:43 +000011706- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
11707 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +000011708
11709- Patch #1733960: Allow T_LONGLONG to accept ints.
11710
11711- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
11712

11716
11717- Fix some leftovers from the conversion from int to Py_ssize_t
11718 (relevant to strings and sequences of more than 2**31 items).
11719
11720- Make _PyGILState_NoteThreadState() static, it was not used anywhere
11721 outside of pystate.c and should not be necessary.
11722
Georg Brandl3ee81df2008-05-17 18:14:43 +000011723- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
11724 absolute imports. In earlier versions they might have used relative
11725 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000011726
Georg Brandl3ee81df2008-05-17 18:14:43 +000011727- Added case insensitive comparison methods ``PyOS_stricmp(char*,
11728 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000011729
Georg Brandl3ee81df2008-05-17 18:14:43 +000011730- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
11731 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +000011736- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
11737 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
11738 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
11739 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000011740
Georg Brandl3ee81df2008-05-17 18:14:43 +000011741- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +000011753- Removed the macfs module. It had been deprecated since Python 2.5.
11754 This lead to the deprecation of macostools.touched() as it relied
11755 solely on macfs and was a no-op under OS X.
