382 int.__pow__. These overflow checks were causing int.__pow__ to produce
383 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100384 compiler optimizing the check away. Also fix similar overflow checks
385 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

399 and its type get caught in a reference cycle, and the instance's
400 deallocator calls one of the methods on the type (e.g. when subclassing

Ned Deily0d0ea482012-02-10 12:59:06 +0100461- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
462 Distutils-based packages with C extension modules may fail because
463 Apple has removed gcc-4.2, the version used to build python.org
464 64-bit/32-bit Pythons. If the user does not explicitly override
465 the default C compiler by setting the CC environment variable,
466 Distutils will now attempt to compile extension modules with clang
467 if gcc-4.2 is required but not found. Also as a convenience, if
468 the user does explicitly set CC, substitute its value as the default
469 compiler in the Distutils LDSHARED configuration variable for OS X.
470 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
471 SDK, neither of which are available in Xcode 4. This change does not
472 attempt to override settings to support their use with Xcode 4.)

744
Ned Deily87e82bb2011-06-28 19:52:59 -0700745- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
746 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
747 interpreter process. This could cause failures in non-Distutils subprocesses
748 and was unreliable since tests or user programs could modify the interpreter
749 environment after Distutils set it. Instead, have Distutils set the the
750 deployment target only in the environment of each build subprocess. It is
751 still possible to globally override the default by setting
752 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
753 greater or equal to the default value, the value with which the interpreter
754 was built.

764
Victor Stinnerc74a6ba2011-06-17 14:06:27 +0200765- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP

781
Barry Warsawc5643282011-07-19 17:06:30 -0400782- sys.setcheckinterval() now updates the current ticker count as well as
783 updating the check interval, so if the user decreases the check interval,
784 the ticker doesn't have to wind down to zero from the old starting point
785 before the new interval takes effect. And if the user increases the
786 interval, it makes sure the new limit takes effect right away rather have an
787 early task switch before recognizing the new interval.

1736 This prevents user-created self-referencing ordered dictionaries from
1737 becoming permanently uncollectable GC garbage. The downside is that

2198
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002199- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2200 start byte and the continuation byte(s) are now considered invalid, instead
2201 of the number of bytes specified by the start byte.
2202 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2203 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2204 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002213- Issue #8748: Fix two issues with comparisons between complex and integer
2214 objects. (1) The comparison could incorrectly return True in some cases
2215 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2216 (2) The comparison raised an OverflowError for large integers, leading
2217 to unpredictable exceptions when combining integers and complex objects
2218 in sets or dicts.
2219
Mark Dickinson81336372010-05-30 12:12:25 +00002220- Issue #5211: Implicit coercion for the complex type is now completely

2358 non-float non-integer argument is now converted to an integer (if possible)
2359 using its __int__ method. Previously, only small arguments were treated this

Georg Brandlfee0f442010-05-22 21:26:21 +00002411- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
2412 operation raises multiple signals and more than one of those signals is
2413 trapped, the specification determines the order in which the signals should be
2414 handled. In many cases this order wasn't being followed, leading to the wrong

2582Core and Builtins
2583-----------------
2584
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002585- Issue #7301: Add environment variable $PYTHONWARNINGS.
2586
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002587- Issue #8329: Don't return the same lists from select.select when no fds are
2588 changed.
2589
Georg Brandlfee0f442010-05-22 21:26:21 +00002590- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002591 on 64-bit machines. The shift count for either left or right shift is
2592 permitted to be up to sys.maxsize.
2593
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002594- Ensure that tokenization of identifiers is not affected by locale.
2595
Georg Brandlfee0f442010-05-22 21:26:21 +00002596- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002597
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002598- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2599
Georg Brandlfee0f442010-05-22 21:26:21 +00002600- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2601 with a non-empty format string. This is an effort to future-proof user
2602 code. If a derived class does not currently implement __format__ but later
2603 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002604 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002605 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002606
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002607- Issue #8268: Old-style classes (not just instances) now support weak
2608 references.
2609

2611 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00002612
Victor Stinnerc7790ed2010-03-22 12:36:28 +00002613- Issue #1583863: An unicode subclass can now override the __unicode__ method

Benjamin Peterson96545892010-03-21 20:21:00 +00002615- Issue #6474: Make error message from passing an inadequate number of keyword
2616 arguments to a function correct.
2617
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00002618- Issue #8164: Don't allow lambda functions to have a docstring.
2619
Victor Stinner66644262010-03-10 22:30:19 +00002620- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002621 (SIGINT). If an error occurs while importing the site module, the error is
2622 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00002623 module.
2624
Collin Winter001a3952010-03-18 21:54:01 +00002625- Code objects now support weak references.

R. David Murray661303f2010-04-13 20:57:40 +00002630- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
2631
Antoine Pitrouf9de5342010-04-05 21:35:07 +00002632- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00002633 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
2634 `ssl.OPENSSL_VERSION_NUMBER`.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00002636- Issue #8310: Allow dis to examine new style classes.
2637
Georg Brandlfee0f442010-05-22 21:26:21 +00002638- Issue #8257: The Decimal construct now accepts a float instance directly,
2639 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002640
2641 >>> Decimal(1.1)
2642 Decimal('1.100000000000000088817841970012523233890533447265625')
2643
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002644- collections.Counter() now supports a subtract() method.
2645
Georg Brandlfee0f442010-05-22 21:26:21 +00002646- The functools module now has a total_ordering() class decorator to simplify
2647 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002648
Georg Brandlfee0f442010-05-22 21:26:21 +00002649- The functools module also adds cmp_to_key() as a tool to transition old-style
2650 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002651
Georg Brandlfee0f442010-05-22 21:26:21 +00002652- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2653 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002654
Georg Brandlfee0f442010-05-22 21:26:21 +00002655- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2656 InvalidOperation instead of returning False. (Comparisons involving a quiet
2657 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2658 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002659
Georg Brandlfee0f442010-05-22 21:26:21 +00002660- Issue #2531: Comparison operations between floats and Decimal instances now
2661 return a result based on the numeric values of the operands; previously they
2662 returned an arbitrary result based on the relative ordering of id(float) and
2663 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002664
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002665- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002666 argument `-` which tells it to read files to compile from stdin. Each line is
2667 read on demand and the named file is compiled immediately. (Original patch by
2668 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002669
Georg Brandlfee0f442010-05-22 21:26:21 +00002670- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
2671 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00002673- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2674 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002675 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002676
Georg Brandlfee0f442010-05-22 21:26:21 +00002677- Comparisons using one of <, <=, >, >= between a complex instance and a
2678 Fractions instance now raise TypeError instead of returning True/False. This
2679 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2680 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00002681
Michael Foorde6410c52010-03-29 20:04:23 +00002682- Addition of ``WeakSet`` to the ``weakref`` module.

2690
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002691- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00002692 didn't support chflags() (for example ZFS under FreeBSD). The error is now
2693 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002694
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00002695- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
2696 deprecated.
2697
Georg Brandlfee0f442010-05-22 21:26:21 +00002698- Issue #7860: platform.uname now reports the correct 'machine' type when Python
2699 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00002700

2705 existing at the same time, causing a Unicode error when configuration code
2706 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00002707
Georg Brandlfee0f442010-05-22 21:26:21 +00002708- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
2709 when logging occurs.

2712 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
2713 reads and writes are always retried by OpenSSL itself.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00002735- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00002736 for ``TimedRotatingFileHandler`` by using the modification time of an existing
2737 log file to compute the next rollover time. If the log file does not exist,
2738 the current time is used as the basis for the computation.

Georg Brandlba83f822010-03-14 09:50:54 +00002748- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
2749 a base64 transfer-encoded payload *after* decoding it; it no longer does.
2750 This is a behavior change, so email's minor version number is now bumped, to

Georg Brandlba83f822010-03-14 09:50:54 +00002784- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2785 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2786 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002787 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2788 inconsistent: __int__ was used for some integer codes but not for others, and
2789 the set of integer codes for which it was used differed between native packing
2790 and standard packing.)

3195-----------------
3196
Georg Brandlba83f822010-03-14 09:50:54 +00003197- The ``__complex__()`` method is now looked up on the class of instances to
3198 make it consistent with other special methods.

3202
Mark Dickinson1b34d252010-01-01 17:27:30 +00003203- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003204 DeprecationWarning when passed a float argument where an integer was expected.
3205 These functions and methods now raise TypeError instead. The majority of the
3206 effects of this change are in the extension modules, but some core functions
3207 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3208 and many unicode/str methods.

3222 of integers: the result of a/b is now correctly rounded for ints a and b (at
3223 least on IEEE 754 platforms), and in particular does not depend on the
3224 internal representation of a long.

3232
Georg Brandlba83f822010-03-14 09:50:54 +00003233 These executables now work properly with the arch(1) command: ``arch -ppc

3375 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003376
Georg Brandlba83f822010-03-14 09:50:54 +00003377- Remove switch from "%f" formatting to "%g" formatting for floats larger than
3378 1e50 in absolute value.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003390
Georg Brandlba83f822010-03-14 09:50:54 +00003391- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3392 decimal string that's guaranteed to round back to x under correct rounding
3393 (with round-half-to-even rounding mode). Previously it gave a string based on
3394 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3395 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3396 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003397
Georg Brandlba83f822010-03-14 09:50:54 +00003398- Issue #7117: On almost all platforms: float-to-string and string-to-float
3399 conversions within Python are now correctly rounded. Places these conversions
3400 occur include: str for floats and complex numbers; the float and complex
3401 constructors; old-style and new-style numeric formatting; serialization and
3402 deserialization of floats and complex numbers using marshal, pickle and json;
3403 parsing of float and imaginary literals in Python code; Decimal-to-float
3404 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003405
Georg Brandlba83f822010-03-14 09:50:54 +00003406 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3407 providing correctly-rounded strtod and dtoa C functions. This code is
3408 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3409 the C compiler. There may be a small number of platforms on which correct
3410 operation of this code cannot be guaranteed, so the code is not used: notably,
3411 this applies to platforms where the C double format is not IEEE 754 binary64,
3412 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3413 and Python's configure script is unable to determine how to change the FPU
3414 precision. On these platforms conversions use the platform strtod and dtoa,
3415 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003417- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3418 uses the correctly-rounded string <-> float conversions described above (when
3419 available), and so produces correctly rounded results that will display nicely
3420 under the float repr. There are two related small changes: (1) round now
3421 accepts any class with an ``__index__()`` method for its second argument (but
3422 no longer accepts floats for the second argument), and (2) an excessively
3423 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3424 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00003566
Georg Brandlba83f822010-03-14 09:50:54 +00003567 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3568 (2) parsing of strings representing infinities and nans was locale aware; and
3569 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00003570
Georg Brandlba83f822010-03-14 09:50:54 +00003571- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3572 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3573 but with at least one decimal point and with a default precision
3574 of 12. Previously, the behavior the same but with a default precision of 6.
3575 This more closely matches ``str()``, and reduces surprises when adding
3576 alignment flags to the empty presentation type. This also affects the new
3577 complex.__format__ in the same way.
3578
3579- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
3580 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00003642 untrackable objects are not tracked by the garbage collector. This can reduce

3651 internal representation of integers, for performance reasons. Base 2**30 is
3652 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandl6425a2f2008-12-28 11:54:53 +00003740- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00003741 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00003742
Skip Montanarof205c132008-12-23 03:30:15 +00003743- Added test case to ensure attempts to read from a file opened for writing
3744 fail.
3745
Georg Brandlba83f822010-03-14 09:50:54 +00003746- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
3747 elapsed times, not only when some objects are uncollectable/unreachable.
3748 Original patch by Neil Schemenauer.
Antoine Pitrou73c0e652008-12-17 22:46:54 +00003749
Mark Dickinson1a707982008-12-17 16:14:37 +00003750- Issue #3439: Add a bit_length method to int and long.
3751
Georg Brandlba83f822010-03-14 09:50:54 +00003752- Issue #2183: Simplify and optimize bytecode for list comprehensions. Original
3753 patch by Neal Norwitz.
Antoine Pitroud0c35152008-12-17 00:38:28 +00003754
Georg Brandlba83f822010-03-14 09:50:54 +00003755- Issue #4597: Fixed exception handling when the __exit__ function of a context
3756 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00003757
Georg Brandlba83f822010-03-14 09:50:54 +00003758- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00003759
Georg Brandlba83f822010-03-14 09:50:54 +00003760- Issue #4445: Replace ``sizeof(PyStringObject)`` with
3761 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
3762 instances. On a typical machine this saves 3 bytes of memory (on average) per
3763 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00003764
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00003765- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
3766 interpreter to abort ("Fatal Python error: Could not reset the stack!")
3767 instead of throwing a MemoryError.
3768
Georg Brandlba83f822010-03-14 09:50:54 +00003769- Issue #3689: The list reversed iterator now supports __length_hint__ instead
3770 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00003771
Benjamin Petersonc078f922008-11-21 22:27:24 +00003772- Issue #4367: Python would segfault during compiling when the unicodedata
3773 module couldn't be imported and \N escapes were present.
3774
Georg Brandlba83f822010-03-14 09:50:54 +00003775- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3776 file objects with closefd=False. The file descriptor is still kept open but
3777 the file object behaves like a closed file. The ``FileIO`` object also got a
3778 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00003779
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00003780- Issue #4348: Some bytearray methods returned that didn't cause any change to
3781 the bytearray, returned the same bytearray instead of a copy.
3782
Georg Brandlba83f822010-03-14 09:50:54 +00003783- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Peterson273c2332008-11-17 22:39:09 +00003785- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
3786
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00003787- Issue #4048: The parser module now correctly validates relative imports.
3788
Benjamin Petersondcee09d2008-10-31 02:16:05 +00003789- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
3790 exec statement.
3791
Georg Brandlba83f822010-03-14 09:50:54 +00003792- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
3793 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00003794
Benjamin Petersonbdca9422008-10-26 20:21:13 +00003795- Issue #4209: Enabling unicode_literals and the print_function in the same
3796 __future__ import didn't work.
3797
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003798- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00003799 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003800
Georg Brandlba83f822010-03-14 09:50:54 +00003801- On windows, ``os.chdir()`` given unicode was not working if
3802 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3803 this code path is really executed because I cannot move to such directory on
3804 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00003805
Georg Brandlba83f822010-03-14 09:50:54 +00003806- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3807 element is temporarily replaced with an equivalent frozenset. But the
3808 eventual KeyError would always report the empty ``frozenset()`` as the missing
3809 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00003810
Georg Brandlba83f822010-03-14 09:50:54 +00003811- Issue #4509: Various issues surrounding resize of bytearray objects to which
3812 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00003813
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00003814- Issue #4748: Lambda generators no longer return a value.

3817
Gregory P. Smithae91d092009-03-02 05:13:57 +00003818- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
3819
Georg Brandlba83f822010-03-14 09:50:54 +00003820- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
3821 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00003822
Matthias Klose91a3b9e2009-04-05 21:19:13 +00003823- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
3824 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00003825
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00003826- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
3827 returned them on 64bit platforms.
3828
Walter Dörwalded960ac2009-05-03 22:36:33 +00003829- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3830 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3831 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3832 of using the replace error handler in PyUnicode_DecodeUTF8().
3833
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003834- Issue #3739: The unicode-internal encoder now reports the number of characters
3835 consumed like any other encoder (instead of the number of bytes).
3836
Georg Brandlba83f822010-03-14 09:50:54 +00003837- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3838 allocator will be automatically disabled when running under Valgrind. This
3839 gives improved memory leak detection when running under Valgrind, while taking
3840 advantage of pymalloc at other times.

Tarek Ziadéa5076a22009-11-29 22:20:30 +00003865- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
3866 ownership when the group is not forced, because the group may be different
3867 from the user's group and inherit from its container when the test is run.

3911 zipfiles, directories and other valid sys.path entries that contain a
Nick Coghlan49868cb2009-11-15 07:30:34 +00003912 __main__.py file. This allows applications that run other Python scripts to

5007 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
5008 neither __int__ nor __long__, TypeError used to be raised (with a
5009 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
5010 struct.error in other cases.

5206
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005207- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5208 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5209 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5210 ``printf`` function, whereas PyString_FromFormat has an independent
5211 implementation and uses "%zd" on all platforms for size_t values.
5212 This makes a difference on win64, where ``printf`` needs "%Id" to display
5213 64bit values.

5219 object; previously an int would be returned for small values. the __long__
5220 method is allowed to return either an int or a long, but the behaviour of

Vinay Sajip35e3b032008-09-01 14:33:59 +00005229 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005230 was correctly parsed but parsing of subsequent arguments failed.
5231
Vinay Sajip35e3b032008-09-01 14:33:59 +00005232- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005233 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5234 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5235 when given a tuple of classes as second argument, were looking up
5236 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5237 type object.
5238
Neal Norwitz18aa3882008-08-24 05:04:52 +00005239- Fix crashes on memory allocation failure found with failmalloc.

5382-----------------
5383
Guido van Rossumf8402962008-08-20 15:01:50 +00005384- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5385 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5386 extensions do not automatically benefit from the class attribute
5387 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5388 to their tp_flags field if they care. This is a backwards
5389 compatibility feature; in 3.0, all types will use the cache by
5390 default.
5391
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005392- Keyword arguments can now follow starred arguments. (``f(a, *args,

5394
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005395- ctypes function pointers that are COM methods have a boolean True

Georg Brandl1e13ea92008-08-11 09:07:59 +00005402- Issue #3537: Fix an assertion failure when an empty but presized dict
5403 object was stored in the freelist.
5404
Mark Dickinsonb6467572008-08-04 21:30:09 +00005405- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5406 ValueError consistently across platforms.
5407
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005408- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5409 (64bit Unix, for example), unichr() would truncate its argument and return
5410 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5411
Neal Norwitze7d8be82008-07-31 17:17:14 +00005412- Apply security patches from Apple.

Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005414- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5415 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5416
Antoine Pitrou92f82162008-07-25 22:22:08 +00005417- Issue #1819: function calls with several named parameters are now on
5418 average 35% faster (as measured by pybench).
5419
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005420- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5421 the python debugger steps into a class statement: the free variables (local
5422 variables defined in an outer scope) would be deleted from the outer scope.
5423
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005424- Issue #2620: Overflow checking when allocating or reallocating memory
5425 was not always being done properly in some python types and extension
5426 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5427 all been updated to perform better checks and places in the code that
5428 would previously leak memory on the error path when such an allocation
5429 failed have been fixed.

Benjamin Petersone977ad42008-08-20 01:42:01 +00005436- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5437 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5438
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005439- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5440 version reported by these tools does not necessarily follow the python
5441 version numbering scheme, so the module is less strict when parsing it.
5442
Nick Coghlanf70385a2008-08-18 12:42:46 +00005443- Issue #2235: Added Py3k warnings for types which will become unhashable
5444 under the stricter __hash__ inheritance rules in 3.0. Several types
5445 which did not meet the rules for hash invariants and were already
5446 unhashable in 3.0 have now been explicitly flagged as unhashable in
5447 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5448 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5449
Brett Cannon88f801d2008-08-18 00:46:22 +00005450- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

Brett Cannonbf3157b2008-08-14 05:00:03 +00005481- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5482 since mimetools itself is deprecated. Because modules are cached, all
5483 subsequent imports of rfc822 will not raise a visible DeprecationWarning.

5497 to _sre.compile() will now be rejected. This should not affect anybody
5498 since the re.compile() function never generates invalid re-bytecode.
5499
Skip Montanaroa032bf42008-08-08 22:52:51 +00005500- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

5502 it wasn't initialized during instantiation.
5503
Brett Cannon3aa2a492008-08-06 22:28:09 +00005504- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5505 the reload() built-in has been removed.
5506
Brett Cannon7e30b672008-08-04 21:52:25 +00005507- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00005519 asking for a specific length. This problem only affected files opened
5520 using the new "io" module, not the built-in open() function.

5546 file name rather than a ZipInfo instance, so files are extracted with
5547 mode 0600 rather than 000 under Unix.
5548
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005549- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5550 argument in python 2.5, this broke code that subclassed Popen to include its

5562 interaction with the tp_hash slot (added in 2.6b2) are now documented
5563
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005564- Issue #643841: The language reference now provides more detailed
5565 coverage of the lookup process for special methods. The disclaimers
5566 regarding lack of coverage of new-style classes have also been
5567 removed, since the coverage is now fairly reasonable.

5571================================
5572
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005573*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005575Core and Builtins
5576-----------------
5577
Georg Brandl3e483f62008-07-16 22:57:41 +00005578- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5579 its methods now allow for items objects that can be converted to
5580 an integer using operator.index().
5581
Mark Dickinson64b7e502008-07-16 09:40:03 +00005582- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5583 produced a ValueError instead of giving the correct float.
5584
Eric Smitha5fa5a22008-07-16 00:11:49 +00005585- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5586 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5587
Mark Dickinson7103aa42008-07-15 19:08:33 +00005588- Issue #3008: the float type has a new instance method 'float.hex'
5589 and a new class method 'float.fromhex' to convert floating-point
5590 numbers to and from hexadecimal strings, respectively.
5591
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005592- Issue #2235: __hash__ is once again inherited by default. To allow
5593 collections.Hashable to remain meaningful in the presence of the
5594 default hash implementation (object.__hash__), it is now possible
5595 to explicit block inheritance of hash by setting __hash__=None at
5596 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5597 level.
5598
Nick Coghlanb028f502008-07-13 14:52:36 +00005599- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5600 the parent module cannot be found while performing an absolute import.
5601 This means that an incorrectly defined __package__ attribute will
5602 now only prevent relative imports in that module rather than causing
5603 all imports from that module to fail.
5604
Nick Coghlan14ff9942008-07-08 14:21:42 +00005605- Issue #2517: Allow unicode messages in Exceptions again by correctly
5606 bypassing the instance dictionary when looking up __unicode__ on
5607 new-style classes.
5608
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005609- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5610 set to a custom object whose write() method happens to install
5611 another file in sys.stdout.
5612
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005613- Issue #3088: Corrected a race condition in classes derived from
5614 threading.local: the first member set by a thread could be saved in
5615 another thread's dictionary.
5616
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005617- Issue #3004: Minor change to slice.indices(): the start and stop
5618 arguments are now treated identically, making the behaviour easier
5619 to describe and understand. For example, slice(None, -10,
5620 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5621 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5622 10, -1).
5623
Georg Brandl278fc502008-07-19 12:46:12 +00005624- Issue #3219: Calling a function with repeated keyword arguments,
5625 f(a=2, a=23), would not cause a syntax error. This was a regression
5626 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005627
Georg Brandl278fc502008-07-19 12:46:12 +00005628- Issue #2862: Make int and float freelist management consistent with
5629 other freelists. Changes their CompactFreeList apis into
5630 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00005631

5634
Thomas Heller57adf222008-08-14 19:10:48 +00005635- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5636 api functions without holding the GIL, which could lead to a fatal
5637 error when they failed.
5638
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005639- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

5648 ForkingPickler.register() to resolve conflict with ctypes.
5649
Vinay Sajip51e65192008-07-18 09:01:10 +00005650- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00005652- Issue #3313: Fixed a crash when a failed dlopen() call does not set
5653 a valid dlerror() message.
5654
Thomas Heller2bad6572008-07-15 17:19:50 +00005655- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5656 incomplete structure was created.
5657
Brett Cannon3d0b9f02008-07-13 01:15:07 +00005658- Issue #3339: dummy_thread.acquire() should not return None.

5661
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005662- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00005663
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005664- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5665 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005666 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005667 content-length. The problem had been corrected in the 2.4 branch, but never
5668 merged into trunk.
5669
Georg Brandle78fbcc2008-07-05 10:13:36 +00005670- Issue #2663: add filtering capability to shutil.copytree().

6075 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006076 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006077
6078 This is controlled by the configure argument ``--with-universal-archs``:
6079
6080 - ``--with-universal-archs=all``: install 4-way universal
6081
6082 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6083
6084 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6085
6086 This option should be used in combination with ``--enable-universalsdk=``.
6087
6088 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 +00006138- Issue #1631171: Re-implement the 'warnings' module in C (the
6139 original Python code has been kept as backup). This will allow for
6140 using the 'warning's machinery in such places as the parser where
6141 use of pure Python code is not possible. Both the ``showarning()``
6142 and ``formatwarning()`` gain an optional 'line' argument which is
6143 not called by default for backwards-compatibility reasons. Setting
6144 ``warnings.showwarning()`` to an implementation that lacks support
6145 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006208- Issue #2550: The approach used by client/server code for obtaining
6209 ports to listen on in network-oriented tests has been refined in an
6210 effort to facilitate running multiple instances of the entire
6211 regression test suite in parallel without issue.
6212 test_support.bind_port() has been fixed such that it will always
6213 return a unique port -- which wasn't always the case with the
6214 previous implementation, especially if socket options had been set
6215 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6216 new implementation of bind_port() will actually raise an exception
6217 if it is passed an AF_INET/SOCK_STREAM socket with either the
6218 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6219 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6220 the socket it's been passed. This currently only applies to
6221 Windows. This option prevents any other sockets from binding to the
6222 host/port we've bound to, thus removing the possibility of the
6223 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6224 when a second SOCK_STREAM socket binds and accepts to a host/port
6225 that's already been bound by another socket. The optional preferred
6226 port parameter to bind_port() has been removed. Under no
6227 circumstances should tests be hard coding ports!
6228
6229 test_support.find_unused_port() has also been introduced, which will
6230 pass a temporary socket object to bind_port() in order to obtain an
6231 unused port. The temporary socket object is then closed and
6232 deleted, and the port is returned. This method should only be used
6233 for obtaining an unused port in order to pass to an external program
6234 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6235 a parameter to a server-oriented class that doesn't give you direct
6236 access to the underlying socket used.
6237
6238 Finally, test_support.HOST has been introduced, which should be used
6239 for the host argument of any relevant socket calls (i.e. bind and
6240 connect).

6516
Fred Drakea8ee94b2008-03-01 02:45:07 +00006517- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00006518 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00006519
Georg Brandlad61bc82008-02-23 15:11:18 +00006520- Issue #2067: file.__exit__() now calls subclasses' close() method.
6521
6522- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00006523
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006524- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00006525 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00006526
Eric Smitha73fbe72008-02-23 03:09:44 +00006527- Added the future_builtins module, which contains hex() and oct().
6528 These are the PEP 3127 version of these functions, designed to be
6529 compatible with the hex() and oct() builtins from Python 3.0. They
6530 differ slightly in their output formats from the existing, unchanged
6531 Python 2.6 builtins. The expected usage of the future_builtins
6532 module is:
6533 from future_builtins import hex, oct
6534
Eric Smith7ef40bf2008-02-20 23:34:22 +00006535- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6536 exponents for exponents with absolute value < 100. Follows C99
6537 standard. This is a change on Windows, which would use 3 digits.
6538 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6539 so that any alterations it does to the resulting string will be
6540 available in stringlib/formatter.h (for float.__format__).
6541
Eric Smith5a3c1352008-02-19 13:21:56 +00006542- Implemented PEP 3101, Advanced String Formatting. This adds a new
6543 builtin format(); a format() method for str and unicode; a
6544 __format__() method to object, str, unicode, int, long, float, and
6545 datetime; the class string.Formatter; and the C API
6546 PyObject_Format().
6547
Georg Brandl3ee81df2008-05-17 18:14:43 +00006548- Fixed several potential crashes, all caused by specially crafted
6549 __del__ methods exploiting objects in temporarily inconsistent
6550 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006551
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006552- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006553 prevent a possible crash: an Abstract Base Class would try to access
6554 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006555
Georg Brandl3ee81df2008-05-17 18:14:43 +00006556- Fixed repr() and str() of complex numbers with infinity or nan as
6557 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00006558
Georg Brandl3ee81df2008-05-17 18:14:43 +00006559- Clear all free lists during a gc.collect() of the highest generation
6560 in order to allow pymalloc to free more arenas. Python may give back
6561 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006562
Georg Brandl3ee81df2008-05-17 18:14:43 +00006563- Issue #2045: Fix an infinite recursion triggered when printing a
6564 subclass of collections.defaultdict, if its default_factory is set
6565 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006566
Christian Heimesf75dbef2008-02-08 00:11:31 +00006567- Fixed a minor memory leak in dictobject.c. The content of the free
6568 list was not freed on interpreter shutdown.
6569
Georg Brandl21e99f42010-03-07 15:23:59 +00006570- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006571 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006572
Georg Brandl3ee81df2008-05-17 18:14:43 +00006573- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6574 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006575 to compact the internal free lists of pre-allocted ints and floats.
6576
Georg Brandl3ee81df2008-05-17 18:14:43 +00006577- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6578 calls. Python expected the return type int but the fork familie
6579 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006580
Georg Brandl3ee81df2008-05-17 18:14:43 +00006581- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6582 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006583
Georg Brandl3ee81df2008-05-17 18:14:43 +00006584- Issue #2025: Add tuple.count() and tuple.index() methods to comply
6585 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00006586
Georg Brandl3ee81df2008-05-17 18:14:43 +00006587- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
6588 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00006589
Georg Brandl3ee81df2008-05-17 18:14:43 +00006590- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6591 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006592
Georg Brandl3ee81df2008-05-17 18:14:43 +00006593- Patch #1473257: generator objects gain a gi_code attribute. This is
6594 the same object as the func_code attribute of the function that
6595 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006596
Georg Brandl3ee81df2008-05-17 18:14:43 +00006597- Issue #1920: "while 0" statements were completely removed by the
6598 compiler, even in the presence of an "else" clause, which is
6599 supposed to be run when the condition is false. Now the compiler
6600 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006601
Guido van Rossumeead05f2008-01-24 18:21:02 +00006602- A few crashers fixed: weakref_in_del.py (issue #1377858);
6603 loosing_dict_ref.py (issue #1303614, test67.py);
6604 borrowed_ref_[34].py (not in tracker).
6605
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006606- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006607 suppressed while an extension is loaded by calling SetErrorMode in
6608 dynload_win.c. The error is still reported properly.
6609
Georg Brandl3ee81df2008-05-17 18:14:43 +00006610- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006611 several extension methods and modules do not work without unicode
6612 support.
6613
Georg Brandl26543b12008-01-21 18:36:51 +00006614- Issue #1882: when compiling code from a string, encoding cookies in the
6615 second line of code were not always recognized correctly.
6616
Georg Brandl14404b62008-01-19 19:27:05 +00006617- Issue #1679: "0x" was taken as a valid integer literal.
6618
Georg Brandl6caad7d2008-01-26 14:19:22 +00006619- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006620 added.
6621
Christian Heimesc94e2b52008-01-14 04:13:37 +00006622- sys.float_info / PyFloat_GetInfo: The floating point information
6623 object was converted from a dict to a specialized structseq object.
6624
Georg Brandl3ee81df2008-05-17 18:14:43 +00006625- Patch #1816: Added sys.flags structseq. It exposes the status of
6626 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006627
Georg Brandl3ee81df2008-05-17 18:14:43 +00006628- Objects/structseq.c: Implemented new structseq representation. The
6629 patch makes structseqs (e.g. the return value of os.stat) more
6630 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006631
Georg Brandl3ee81df2008-05-17 18:14:43 +00006632- Patch #1700288: added a type attribute cache that caches method
6633 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006634
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006635- Bug #1776: __import__() no longer accepts filenames on any platform.
6636 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006637
Georg Brandlaed6c662008-01-07 17:25:53 +00006638- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6639
Georg Brandl3ee81df2008-05-17 18:14:43 +00006640- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6641 envvar and sys.dont_write_bytecode attribute. All these can be set
6642 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006643
Georg Brandl3ee81df2008-05-17 18:14:43 +00006644- Improve some exception messages when Windows fails to load an
6645 extension module. Now we get for example '%1 is not a valid Win32
6646 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006647
Georg Brandl3ee81df2008-05-17 18:14:43 +00006648- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006650- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
6651 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006652
Christian Heimes0a8143f2007-12-18 23:22:54 +00006653- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006654 and INF. float("nan"), float("inf") and float("-inf") now work on
6655 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006656
Georg Brandl3ee81df2008-05-17 18:14:43 +00006657- Compiler now generates simpler and faster code for dictionary
6658 literals. The oparg for BUILD_MAP now indicates an estimated
6659 dictionary size. There is a new opcode, STORE_MAP, for adding
6660 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00006661
Georg Brandl3ee81df2008-05-17 18:14:43 +00006662- Issue #1638: %zd configure test fails on Linux.

6672
Nick Coghlanef01d822007-12-03 12:55:17 +00006673- PEP 366: Allow explicit relative imports when executing modules
6674 inside packages with the -m switch via a new module level
6675 __package__ attribute.
6676
Georg Brandl3ee81df2008-05-17 18:14:43 +00006677- Issue #1402: Fix a crash on exit, when another thread is still
6678 running, and if the deallocation of its frames somehow calls the
6679 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00006680

Georg Brandl3ee81df2008-05-17 18:14:43 +00006694- Issue #1265: Fix a problem with sys.settrace, if the tracing
6695 function uses a generator expression when at the same time the
6696 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006697
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006698- sets and frozensets now have an isdisjoint() method.
6699
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006700- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00006702- Fix warnings found by the new version of the Coverity checker.
6703
Georg Brandl21e99f42010-03-07 15:23:59 +00006704- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006705 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6706 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006707
Georg Brandl3ee81df2008-05-17 18:14:43 +00006708- Issue #1686386: Tuple's tp_repr did not take into account the
6709 possibility of having a self-referential tuple, which is possible
6710 from C code. Nor did object's tp_str consider that a type's tp_str
6711 could do something that could lead to an inifinite recursion.
6712 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6713 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006714
Georg Brandl3ee81df2008-05-17 18:14:43 +00006715- Issue #1164: It was possible to trigger deadlock when using the
6716 'print' statement to write to a file since the GIL was not released
6717 as needed. Now PyObject_Print() does the right thing along with
6718 various tp_print implementations of the built-in types and those in
6719 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006720
Georg Brandl3ee81df2008-05-17 18:14:43 +00006721- Issue #1147: Exceptions were directly allowing string exceptions in
6722 their throw() method even though string exceptions no longer
6723 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006724

Brett Cannon1e534b52007-09-07 04:18:30 +00006728- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006729 PyObject_Call() never calling back out to Python code to trigger
6730 recursion depth updates/checks. Required the creation of a static
6731 RuntimeError instance in case normalizing an exception put the

Georg Brandl3ee81df2008-05-17 18:14:43 +00006749 __*__ attributes. (Some already existed, e.g., __doc__ and
6750 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006751

6760 with Python 3.0.

6780
Guido van Rossum143b5642007-03-23 04:58:42 +00006781- Bug #1683368: The object.__init__() and object.__new__() methods are
6782 now stricter in rejecting excess arguments. The only time when
6783 either allows excess arguments is when it is not overridden and the
6784 other one is. For backwards compatibility, when both are
6785 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006786 warning later). Also, type.__init__() insists on the same signature
6787 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006789- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6790 object to complex using its __complex__() method before falling back
6791 to the __float__() method. Therefore, the functions in the cmath
6792 module now can operate on objects that define a __complex__()
6793 method.

6810
Georg Brandl7b9c5552007-03-12 14:30:05 +00006811- Bug #1678647: write a newline after printing an exception in any
6812 case, even when converting the value to a string failed.
6813
Georg Brandl871f1bc2007-03-12 13:17:36 +00006814- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006815 its argument, if it exists. If not, it will work like before. This
6816 allows customizing the output of dir() in the presence of a
6817 __getattr__().

6827 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006828
Georg Brandlaa2321b2007-03-07 00:40:28 +00006829- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006830 makes the filenames the warning module prints much more sensible
6831 when a PYTHONSTARTUP file is used.

6845 sq_ass_slice instead of the sq_slice slot.
6846
Georg Brandl3ee81df2008-05-17 18:14:43 +00006847- When printing an unraisable error, don't print exceptions. before

7475 accepted in TestSuite.addTest(). This should cause no
7476 incompatibility since it never made sense with ordinary subclasses
7477 -- the failure just occurred later, with a more cumbersome
7478 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007759- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7760 with RFC 3207 and forgets any knowledge obtained from the server not
7761 obtained from the TLS negotiation itself. Patch contributed by Bill
7762 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007763
Georg Brandl3ee81df2008-05-17 18:14:43 +00007764- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007765 that the SMTP.starttls() caller no longer needs to call ehlo()
7766 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007767 does not claim to support starttls. Adds the
7768 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

7849 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7850 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00007867 time so that opening a database previously created with the DB_DUP
7868 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7869 opens. Specifically: dictionary assignment to a DB object will
7870 replace all values for a given key when the database allows
7871 duplicate values. DB users should use DB.put(k, v) when they want
7872 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007873

7879 characters with ASCII value less than 32. Also, it correctly quotes
7880 dots only if they occur on a single line, as opposed to the previous
7881 behavior of quoting dots if they are the second character of any
7882 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007883

Georg Brandl3ee81df2008-05-17 18:14:43 +00008199- Makefile.pre.in(buildbottest): Run an optional script
8200 pybuildbot.identify to include some information about the build
8201 environment.

8205-----
8206
Georg Brandl3ee81df2008-05-17 18:14:43 +00008207- Unified naming convention for free lists and their limits. All free
8208 lists in Object/ are named ``free_list``, the counter ``numfree``
8209 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
8210 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00008211
Georg Brandl3ee81df2008-05-17 18:14:43 +00008212- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8213 to ``PyTuple_SetItem``, it can be used to populate a brand new
8214 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00008215
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008216- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00008217
Georg Brandl3ee81df2008-05-17 18:14:43 +00008218- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
8219 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
8220 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008221
8222- Patch #1720595: add T_BOOL to the range of structmember types.
8223
8224- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
8225 ``PyFloat_GetInfo()`` to the float API.
8226
Georg Brandl3ee81df2008-05-17 18:14:43 +00008227- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8228 of w# format code incorrectly truncated the length to an int, even
8229 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8230 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008231
Georg Brandl3ee81df2008-05-17 18:14:43 +00008232- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
8233 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008234
Georg Brandl3ee81df2008-05-17 18:14:43 +00008235- PEP 3123: Provide forward compatibility with Python 3.0, while
8236 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
8237 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008238
Georg Brandl3ee81df2008-05-17 18:14:43 +00008239- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
8240 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008241
8242- Patch #1733960: Allow T_LONGLONG to accept ints.
8243
8244- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
8245
Christian Heimes000a0742008-01-03 22:16:32 +00008246- Added a new API function ``PyImport_ImportModuleNoBlock``.
8247
Georg Brandl6caad7d2008-01-26 14:19:22 +00008248- Bug #1637022: Prefix AST symbols with _Py_.
8249
8250- Fix some leftovers from the conversion from int to Py_ssize_t
8251 (relevant to strings and sequences of more than 2**31 items).
8252
8253- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8254 outside of pystate.c and should not be necessary.
8255
Georg Brandl3ee81df2008-05-17 18:14:43 +00008256- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8257 absolute imports. In earlier versions they might have used relative
8258 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008259
Georg Brandl3ee81df2008-05-17 18:14:43 +00008260- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8261 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008262
Georg Brandl3ee81df2008-05-17 18:14:43 +00008263- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
8264 macro so it can be used as an expression.

8269
Georg Brandl3ee81df2008-05-17 18:14:43 +00008270- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
8271 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
8272 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
8273 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00008274
Georg Brandl3ee81df2008-05-17 18:14:43 +00008275- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
8276 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008288- Removed the macfs module. It had been deprecated since Python 2.5.
8289 This lead to the deprecation of macostools.touched() as it relied
8290 solely on macfs and was a no-op under OS X.
