377 int.__pow__. These overflow checks were causing int.__pow__ to produce
378 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100379 compiler optimizing the check away. Also fix similar overflow checks
380 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

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

Ned Deilyc47a4592012-02-11 20:40:24 +0100450 has left two versions of customize_compiler, the original in
451 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +0100456- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
457 Distutils-based packages with C extension modules may fail because
458 Apple has removed gcc-4.2, the version used to build python.org
459 64-bit/32-bit Pythons. If the user does not explicitly override
460 the default C compiler by setting the CC environment variable,
461 Distutils will now attempt to compile extension modules with clang
462 if gcc-4.2 is required but not found. Also as a convenience, if
463 the user does explicitly set CC, substitute its value as the default
464 compiler in the Distutils LDSHARED configuration variable for OS X.
465 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
466 SDK, neither of which are available in Xcode 4. This change does not
467 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700740- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
741 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
742 interpreter process. This could cause failures in non-Distutils subprocesses
743 and was unreliable since tests or user programs could modify the interpreter
744 environment after Distutils set it. Instead, have Distutils set the the
745 deployment target only in the environment of each build subprocess. It is
746 still possible to globally override the default by setting
747 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
748 greater or equal to the default value, the value with which the interpreter
749 was built.

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

1731 This prevents user-created self-referencing ordered dictionaries from
1732 becoming permanently uncollectable GC garbage. The downside is that
1733 removing __del__ means that the internal doubly-linked list has to wait for
1734 GC collection rather than freeing memory immediately when the refcnt drops

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002194- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2195 start byte and the continuation byte(s) are now considered invalid, instead
2196 of the number of bytes specified by the start byte.
2197 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2198 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2199 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002208- Issue #8748: Fix two issues with comparisons between complex and integer
2209 objects. (1) The comparison could incorrectly return True in some cases
2210 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2211 (2) The comparison raised an OverflowError for large integers, leading

Georg Brandlfee0f442010-05-22 21:26:21 +00002352- Issue #1533: Fix inconsistency in range function argument processing: any
2353 non-float non-integer argument is now converted to an integer (if possible)
2354 using its __int__ method. Previously, only small arguments were treated this
2355 way; larger arguments (those whose __int__ was outside the range of a C long)

Georg Brandlfee0f442010-05-22 21:26:21 +00002406- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
2407 operation raises multiple signals and more than one of those signals is
2408 trapped, the specification determines the order in which the signals should be
2409 handled. In many cases this order wasn't being followed, leading to the wrong
2410 Python exception being raised.

2577Core and Builtins
2578-----------------
2579
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002580- Issue #7301: Add environment variable $PYTHONWARNINGS.
2581
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002582- Issue #8329: Don't return the same lists from select.select when no fds are
2583 changed.
2584
Georg Brandlfee0f442010-05-22 21:26:21 +00002585- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002586 on 64-bit machines. The shift count for either left or right shift is
2587 permitted to be up to sys.maxsize.
2588
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002589- Ensure that tokenization of identifiers is not affected by locale.
2590
Georg Brandlfee0f442010-05-22 21:26:21 +00002591- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002592
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002593- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2594
Georg Brandlfee0f442010-05-22 21:26:21 +00002595- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2596 with a non-empty format string. This is an effort to future-proof user
2597 code. If a derived class does not currently implement __format__ but later
2598 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002599 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002600 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002601
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002602- Issue #8268: Old-style classes (not just instances) now support weak
2603 references.
2604
Georg Brandlfee0f442010-05-22 21:26:21 +00002605- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
2606 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00002607
Victor Stinnerc7790ed2010-03-22 12:36:28 +00002608- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +00002609
Benjamin Peterson96545892010-03-21 20:21:00 +00002610- Issue #6474: Make error message from passing an inadequate number of keyword
2611 arguments to a function correct.
2612
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00002613- Issue #8164: Don't allow lambda functions to have a docstring.
2614
Victor Stinner66644262010-03-10 22:30:19 +00002615- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002616 (SIGINT). If an error occurs while importing the site module, the error is
2617 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00002618 module.
2619
Collin Winter001a3952010-03-18 21:54:01 +00002620- Code objects now support weak references.

R. David Murray661303f2010-04-13 20:57:40 +00002625- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
2626
Antoine Pitrouf9de5342010-04-05 21:35:07 +00002627- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00002628 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
2629 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +00002630
Benjamin Peterson76a23c12010-04-04 23:23:22 +00002631- Issue #8310: Allow dis to examine new style classes.
2632
Georg Brandlfee0f442010-05-22 21:26:21 +00002633- Issue #8257: The Decimal construct now accepts a float instance directly,
2634 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002635
2636 >>> Decimal(1.1)
2637 Decimal('1.100000000000000088817841970012523233890533447265625')
2638
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002639- collections.Counter() now supports a subtract() method.
2640
Georg Brandlfee0f442010-05-22 21:26:21 +00002641- The functools module now has a total_ordering() class decorator to simplify
2642 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002643
Georg Brandlfee0f442010-05-22 21:26:21 +00002644- The functools module also adds cmp_to_key() as a tool to transition old-style
2645 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002646
Georg Brandlfee0f442010-05-22 21:26:21 +00002647- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2648 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002649
Georg Brandlfee0f442010-05-22 21:26:21 +00002650- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2651 InvalidOperation instead of returning False. (Comparisons involving a quiet
2652 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2653 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002654
Georg Brandlfee0f442010-05-22 21:26:21 +00002655- Issue #2531: Comparison operations between floats and Decimal instances now
2656 return a result based on the numeric values of the operands; previously they
2657 returned an arbitrary result based on the relative ordering of id(float) and
2658 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002659
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002660- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002661 argument `-` which tells it to read files to compile from stdin. Each line is
2662 read on demand and the named file is compiled immediately. (Original patch by
2663 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002664
Georg Brandlfee0f442010-05-22 21:26:21 +00002665- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
2666 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00002668- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2669 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002670 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002671
Georg Brandlfee0f442010-05-22 21:26:21 +00002672- Comparisons using one of <, <=, >, >= between a complex instance and a
2673 Fractions instance now raise TypeError instead of returning True/False. This
2674 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2675 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00002676
Michael Foorde6410c52010-03-29 20:04:23 +00002677- Addition of ``WeakSet`` to the ``weakref`` module.

2685
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002686- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00002687 didn't support chflags() (for example ZFS under FreeBSD). The error is now
2688 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002689
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00002690- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
2691 deprecated.
2692
Georg Brandlfee0f442010-05-22 21:26:21 +00002693- Issue #7860: platform.uname now reports the correct 'machine' type when Python
2694 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00002695

Georg Brandlfee0f442010-05-22 21:26:21 +00002699- Issue #8201: logging: Handle situation of non-ASCII and Unicode logger names
2700 existing at the same time, causing a Unicode error when configuration code
2701 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00002702
Georg Brandlfee0f442010-05-22 21:26:21 +00002703- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
2704 when logging occurs.
Vinay Sajip3017a7b2010-03-22 12:33:08 +00002705
Antoine Pitroueee91cd2010-03-26 19:27:16 +00002706- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
2707 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
2708 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +00002709
Florent Xiclunacf82fa62010-03-21 12:27:20 +00002710- Issue #8179: Fix macpath.realpath() on a non-existing path.

Georg Brandlfee0f442010-05-22 21:26:21 +00002714- Issue #8104: socket.recv_into() and socket.recvfrom_into() now support writing
2715 into objects supporting the new buffer API, for example bytearrays or
2716 memoryviews.
Antoine Pitroud7b731d2010-03-17 22:45:39 +00002717
Matthias Klose8b411682010-03-16 10:48:52 +00002718- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
2719 with Tcl/Tk-8.5.
2720

2724 locale.
Matthias Klose358e7ff2010-03-15 13:42:23 +00002725
Georg Brandlfee0f442010-05-22 21:26:21 +00002726- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been set

Vinay Sajipecfa08f2010-03-12 09:16:10 +00002730- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00002731 for ``TimedRotatingFileHandler`` by using the modification time of an existing
2732 log file to compute the next rollover time. If the log file does not exist,
2733 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00002734
Georg Brandlba83f822010-03-14 09:50:54 +00002735- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

2742
Georg Brandlba83f822010-03-14 09:50:54 +00002743- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
2744 a base64 transfer-encoded payload *after* decoding it; it no longer does.
2745 This is a behavior change, so email's minor version number is now bumped, to
2746 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +00002747

Mark Dickinson4846a8e2010-04-03 14:05:10 +00002774- Issue #8300: When passing a non-integer argument to struct.pack with any
2775 integer format code, struct.pack first attempts to convert the non-integer
2776 using its __index__ method. If that method is non-existent or raises
2777 TypeError it goes on to try the __int__ method, as described below.
2778
Georg Brandlba83f822010-03-14 09:50:54 +00002779- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2780 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2781 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002782 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2783 inconsistent: __int__ was used for some integer codes but not for others, and
2784 the set of integer codes for which it was used differed between native packing
2785 and standard packing.)

3190-----------------
3191
Georg Brandlba83f822010-03-14 09:50:54 +00003192- The ``__complex__()`` method is now looked up on the class of instances to
3193 make it consistent with other special methods.

3197
Mark Dickinson1b34d252010-01-01 17:27:30 +00003198- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003199 DeprecationWarning when passed a float argument where an integer was expected.
3200 These functions and methods now raise TypeError instead. The majority of the
3201 effects of this change are in the extension modules, but some core functions
3202 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3203 and many unicode/str methods.

3217 of integers: the result of a/b is now correctly rounded for ints a and b (at
3218 least on IEEE 754 platforms), and in particular does not depend on the
3219 internal representation of a long.

3227
Georg Brandlba83f822010-03-14 09:50:54 +00003228 These executables now work properly with the arch(1) command: ``arch -ppc
3229 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00003368- Issue #3382: 'F' formatting for float and complex now convert the result to
3369 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
3370 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003371
Georg Brandlba83f822010-03-14 09:50:54 +00003372- Remove switch from "%f" formatting to "%g" formatting for floats larger than
3373 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00003374
Georg Brandlba83f822010-03-14 09:50:54 +00003375- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
3376 1e-100 used to raise OverflowError, but now gives the requested 120
3377 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003385
Georg Brandlba83f822010-03-14 09:50:54 +00003386- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3387 decimal string that's guaranteed to round back to x under correct rounding
3388 (with round-half-to-even rounding mode). Previously it gave a string based on
3389 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3390 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3391 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003392
Georg Brandlba83f822010-03-14 09:50:54 +00003393- Issue #7117: On almost all platforms: float-to-string and string-to-float
3394 conversions within Python are now correctly rounded. Places these conversions
3395 occur include: str for floats and complex numbers; the float and complex
3396 constructors; old-style and new-style numeric formatting; serialization and
3397 deserialization of floats and complex numbers using marshal, pickle and json;
3398 parsing of float and imaginary literals in Python code; Decimal-to-float
3399 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003400
Georg Brandlba83f822010-03-14 09:50:54 +00003401 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3402 providing correctly-rounded strtod and dtoa C functions. This code is
3403 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3404 the C compiler. There may be a small number of platforms on which correct
3405 operation of this code cannot be guaranteed, so the code is not used: notably,
3406 this applies to platforms where the C double format is not IEEE 754 binary64,
3407 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3408 and Python's configure script is unable to determine how to change the FPU
3409 precision. On these platforms conversions use the platform strtod and dtoa,
3410 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003411
Georg Brandlba83f822010-03-14 09:50:54 +00003412- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3413 uses the correctly-rounded string <-> float conversions described above (when
3414 available), and so produces correctly rounded results that will display nicely
3415 under the float repr. There are two related small changes: (1) round now
3416 accepts any class with an ``__index__()`` method for its second argument (but
3417 no longer accepts floats for the second argument), and (2) an excessively
3418 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3419 raises an exception.

3422
Georg Brandlba83f822010-03-14 09:50:54 +00003423- Fix several issues with ``compile()``. The input can now contain Windows and

Mark Dickinsonb1d45852009-05-11 15:33:08 +00003561
Georg Brandlba83f822010-03-14 09:50:54 +00003562 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3563 (2) parsing of strings representing infinities and nans was locale aware; and
3564 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00003565
Georg Brandlba83f822010-03-14 09:50:54 +00003566- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3567 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3568 but with at least one decimal point and with a default precision
3569 of 12. Previously, the behavior the same but with a default precision of 6.
3570 This more closely matches ``str()``, and reduces surprises when adding
3571 alignment flags to the empty presentation type. This also affects the new
3572 complex.__format__ in the same way.
3573
3574- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
3575 classtype's, even if it was None. property now inserts the __doc__ into the

3646 internal representation of integers, for performance reasons. Base 2**30 is
3647 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandl6425a2f2008-12-28 11:54:53 +00003735- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00003736 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00003737
Skip Montanarof205c132008-12-23 03:30:15 +00003738- Added test case to ensure attempts to read from a file opened for writing
3739 fail.
3740
Georg Brandlba83f822010-03-14 09:50:54 +00003741- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
3742 elapsed times, not only when some objects are uncollectable/unreachable.
3743 Original patch by Neil Schemenauer.
Antoine Pitrou73c0e652008-12-17 22:46:54 +00003744
Mark Dickinson1a707982008-12-17 16:14:37 +00003745- Issue #3439: Add a bit_length method to int and long.
3746
Georg Brandlba83f822010-03-14 09:50:54 +00003747- Issue #2183: Simplify and optimize bytecode for list comprehensions. Original
3748 patch by Neal Norwitz.
Antoine Pitroud0c35152008-12-17 00:38:28 +00003749
Georg Brandlba83f822010-03-14 09:50:54 +00003750- Issue #4597: Fixed exception handling when the __exit__ function of a context
3751 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00003752
Georg Brandlba83f822010-03-14 09:50:54 +00003753- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00003754
Georg Brandlba83f822010-03-14 09:50:54 +00003755- Issue #4445: Replace ``sizeof(PyStringObject)`` with
3756 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
3757 instances. On a typical machine this saves 3 bytes of memory (on average) per
3758 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00003759
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00003760- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
3761 interpreter to abort ("Fatal Python error: Could not reset the stack!")
3762 instead of throwing a MemoryError.
3763
Georg Brandlba83f822010-03-14 09:50:54 +00003764- Issue #3689: The list reversed iterator now supports __length_hint__ instead
3765 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00003766
Benjamin Petersonc078f922008-11-21 22:27:24 +00003767- Issue #4367: Python would segfault during compiling when the unicodedata
3768 module couldn't be imported and \N escapes were present.
3769
Georg Brandlba83f822010-03-14 09:50:54 +00003770- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3771 file objects with closefd=False. The file descriptor is still kept open but
3772 the file object behaves like a closed file. The ``FileIO`` object also got a
3773 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00003774
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00003775- Issue #4348: Some bytearray methods returned that didn't cause any change to
3776 the bytearray, returned the same bytearray instead of a copy.
3777
Georg Brandlba83f822010-03-14 09:50:54 +00003778- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Peterson273c2332008-11-17 22:39:09 +00003780- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
3781
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00003782- Issue #4048: The parser module now correctly validates relative imports.
3783
Benjamin Petersondcee09d2008-10-31 02:16:05 +00003784- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
3785 exec statement.
3786
Georg Brandlba83f822010-03-14 09:50:54 +00003787- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
3788 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00003789
Benjamin Petersonbdca9422008-10-26 20:21:13 +00003790- Issue #4209: Enabling unicode_literals and the print_function in the same
3791 __future__ import didn't work.
3792
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003793- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00003794 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003795
Georg Brandlba83f822010-03-14 09:50:54 +00003796- On windows, ``os.chdir()`` given unicode was not working if
3797 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3798 this code path is really executed because I cannot move to such directory on
3799 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00003800
Georg Brandlba83f822010-03-14 09:50:54 +00003801- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3802 element is temporarily replaced with an equivalent frozenset. But the
3803 eventual KeyError would always report the empty ``frozenset()`` as the missing
3804 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00003805
Georg Brandlba83f822010-03-14 09:50:54 +00003806- Issue #4509: Various issues surrounding resize of bytearray objects to which
3807 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00003808
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00003809- Issue #4748: Lambda generators no longer return a value.

3812
Gregory P. Smithae91d092009-03-02 05:13:57 +00003813- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
3814
Georg Brandlba83f822010-03-14 09:50:54 +00003815- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
3816 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00003817
Matthias Klose91a3b9e2009-04-05 21:19:13 +00003818- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
3819 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00003820
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00003821- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
3822 returned them on 64bit platforms.
3823
Walter Dörwalded960ac2009-05-03 22:36:33 +00003824- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3825 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3826 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3827 of using the replace error handler in PyUnicode_DecodeUTF8().
3828
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003829- Issue #3739: The unicode-internal encoder now reports the number of characters
3830 consumed like any other encoder (instead of the number of bytes).
3831
Georg Brandlba83f822010-03-14 09:50:54 +00003832- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3833 allocator will be automatically disabled when running under Valgrind. This
3834 gives improved memory leak detection when running under Valgrind, while taking
3835 advantage of pymalloc at other times.

3862 from the user's group and inherit from its container when the test is run.

5002 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
5003 neither __int__ nor __long__, TypeError used to be raised (with a
5004 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
5005 struct.error in other cases.

5098 should cause a test to be skipped are now done using import_module from test
5099 support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005200- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5201
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005202- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5203 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5204 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5205 ``printf`` function, whereas PyString_FromFormat has an independent
5206 implementation and uses "%zd" on all platforms for size_t values.
5207 This makes a difference on win64, where ``printf`` needs "%Id" to display
5208 64bit values.

5214 object; previously an int would be returned for small values. the __long__
5215 method is allowed to return either an int or a long, but the behaviour of

Vinay Sajip35e3b032008-09-01 14:33:59 +00005224 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005225 was correctly parsed but parsing of subsequent arguments failed.
5226
Vinay Sajip35e3b032008-09-01 14:33:59 +00005227- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005228 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5229 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5230 when given a tuple of classes as second argument, were looking up
5231 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5232 type object.
5233
Neal Norwitz18aa3882008-08-24 05:04:52 +00005234- Fix crashes on memory allocation failure found with failmalloc.

5377-----------------
5378
Guido van Rossumf8402962008-08-20 15:01:50 +00005379- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5380 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5381 extensions do not automatically benefit from the class attribute
5382 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5383 to their tp_flags field if they care. This is a backwards
5384 compatibility feature; in 3.0, all types will use the cache by
5385 default.
5386
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005387- Keyword arguments can now follow starred arguments. (``f(a, *args,
5388 keyword=23)`` is now valid syntax.)
5389
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005390- ctypes function pointers that are COM methods have a boolean True

Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005393- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5394 by denying s# to parse objects that have a releasebuffer procedure,
5395 and introducing s*.

Georg Brandl1e13ea92008-08-11 09:07:59 +00005397- Issue #3537: Fix an assertion failure when an empty but presized dict
5398 object was stored in the freelist.
5399
Mark Dickinsonb6467572008-08-04 21:30:09 +00005400- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5401 ValueError consistently across platforms.
5402
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005403- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5404 (64bit Unix, for example), unichr() would truncate its argument and return
5405 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5406
Neal Norwitze7d8be82008-07-31 17:17:14 +00005407- Apply security patches from Apple.
5408
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005409- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5410 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5411
Antoine Pitrou92f82162008-07-25 22:22:08 +00005412- Issue #1819: function calls with several named parameters are now on
5413 average 35% faster (as measured by pybench).
5414
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005415- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5416 the python debugger steps into a class statement: the free variables (local
5417 variables defined in an outer scope) would be deleted from the outer scope.
5418
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005419- Issue #2620: Overflow checking when allocating or reallocating memory
5420 was not always being done properly in some python types and extension
5421 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5422 all been updated to perform better checks and places in the code that
5423 would previously leak memory on the error path when such an allocation
5424 failed have been fixed.

5430
Benjamin Petersone977ad42008-08-20 01:42:01 +00005431- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5432 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5433
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005434- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5435 version reported by these tools does not necessarily follow the python
5436 version numbering scheme, so the module is less strict when parsing it.
5437
Nick Coghlanf70385a2008-08-18 12:42:46 +00005438- Issue #2235: Added Py3k warnings for types which will become unhashable
5439 under the stricter __hash__ inheritance rules in 3.0. Several types
5440 which did not meet the rules for hash invariants and were already
5441 unhashable in 3.0 have now been explicitly flagged as unhashable in
5442 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5443 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5444
Brett Cannon88f801d2008-08-18 00:46:22 +00005445- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

5474 thread-safe.
5475
Brett Cannonbf3157b2008-08-14 05:00:03 +00005476- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5477 since mimetools itself is deprecated. Because modules are cached, all
5478 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5479
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005480- Issue #3134: shutil referenced undefined WindowsError symbol.

5489 a MemoryError rather than silently stop the iteration.
5490
Guido van Rossum59ce9012008-08-09 14:55:34 +00005491- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5492 to _sre.compile() will now be rejected. This should not affect anybody
5493 since the re.compile() function never generates invalid re-bytecode.
5494
Skip Montanaroa032bf42008-08-08 22:52:51 +00005495- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5496 upon first access it can be automatically initialized from the csv file if
5497 it wasn't initialized during instantiation.
5498
Brett Cannon3aa2a492008-08-06 22:28:09 +00005499- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5500 the reload() built-in has been removed.
5501
Brett Cannon7e30b672008-08-04 21:52:25 +00005502- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005503 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00005514 asking for a specific length. This problem only affected files opened
5515 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005516

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005540- Issue #3394: zipfile.writestr sets external attributes when passed a
5541 file name rather than a ZipInfo instance, so files are extracted with
5542 mode 0600 rather than 000 under Unix.
5543
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005544- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5545 argument in python 2.5, this broke code that subclassed Popen to include its
5546 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00005556- Issue #2235: the C API function PyObject_HashNotImplemented and its
5557 interaction with the tp_hash slot (added in 2.6b2) are now documented
5558
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005559- Issue #643841: The language reference now provides more detailed
5560 coverage of the lookup process for special methods. The disclaimers
5561 regarding lack of coverage of new-style classes have also been
5562 removed, since the coverage is now fairly reasonable.

5566================================
5567
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005568*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005570Core and Builtins
5571-----------------
5572
Georg Brandl3e483f62008-07-16 22:57:41 +00005573- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5574 its methods now allow for items objects that can be converted to
5575 an integer using operator.index().
5576
Mark Dickinson64b7e502008-07-16 09:40:03 +00005577- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5578 produced a ValueError instead of giving the correct float.
5579
Eric Smitha5fa5a22008-07-16 00:11:49 +00005580- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5581 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5582
Mark Dickinson7103aa42008-07-15 19:08:33 +00005583- Issue #3008: the float type has a new instance method 'float.hex'
5584 and a new class method 'float.fromhex' to convert floating-point
5585 numbers to and from hexadecimal strings, respectively.
5586
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005587- Issue #2235: __hash__ is once again inherited by default. To allow
5588 collections.Hashable to remain meaningful in the presence of the
5589 default hash implementation (object.__hash__), it is now possible
5590 to explicit block inheritance of hash by setting __hash__=None at
5591 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5592 level.
5593
Nick Coghlanb028f502008-07-13 14:52:36 +00005594- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5595 the parent module cannot be found while performing an absolute import.
5596 This means that an incorrectly defined __package__ attribute will
5597 now only prevent relative imports in that module rather than causing
5598 all imports from that module to fail.
5599
Nick Coghlan14ff9942008-07-08 14:21:42 +00005600- Issue #2517: Allow unicode messages in Exceptions again by correctly
5601 bypassing the instance dictionary when looking up __unicode__ on
5602 new-style classes.
5603
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005604- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5605 set to a custom object whose write() method happens to install
5606 another file in sys.stdout.
5607
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005608- Issue #3088: Corrected a race condition in classes derived from
5609 threading.local: the first member set by a thread could be saved in
5610 another thread's dictionary.
5611
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005612- Issue #3004: Minor change to slice.indices(): the start and stop
5613 arguments are now treated identically, making the behaviour easier
5614 to describe and understand. For example, slice(None, -10,
5615 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5616 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5617 10, -1).
5618
Georg Brandl278fc502008-07-19 12:46:12 +00005619- Issue #3219: Calling a function with repeated keyword arguments,
5620 f(a=2, a=23), would not cause a syntax error. This was a regression
5621 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005622
Georg Brandl278fc502008-07-19 12:46:12 +00005623- Issue #2862: Make int and float freelist management consistent with
5624 other freelists. Changes their CompactFreeList apis into
5625 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00005626

5628-------
5629
Thomas Heller57adf222008-08-14 19:10:48 +00005630- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5631 api functions without holding the GIL, which could lead to a fatal
5632 error when they failed.
5633
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005634- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

5643 ForkingPickler.register() to resolve conflict with ctypes.
5644
Vinay Sajip51e65192008-07-18 09:01:10 +00005645- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00005646
Thomas Heller880f5292008-07-15 19:39:38 +00005647- Issue #3313: Fixed a crash when a failed dlopen() call does not set
5648 a valid dlerror() message.
5649
Thomas Heller2bad6572008-07-15 17:19:50 +00005650- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5651 incomplete structure was created.
5652
Brett Cannon3d0b9f02008-07-13 01:15:07 +00005653- Issue #3339: dummy_thread.acquire() should not return None.

5656
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005657- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00005658
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005659- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5660 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005661 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005662 content-length. The problem had been corrected in the 2.4 branch, but never
5663 merged into trunk.
5664
Georg Brandle78fbcc2008-07-05 10:13:36 +00005665- Issue #2663: add filtering capability to shutil.copytree().

6068
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006069- On MacOS X it is now possible to install the framework in 64-bit
6070 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006071 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006072
6073 This is controlled by the configure argument ``--with-universal-archs``:
6074
6075 - ``--with-universal-archs=all``: install 4-way universal
6076
6077 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6078
6079 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6080
6081 This option should be used in combination with ``--enable-universalsdk=``.
6082
6083 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 +00006133- Issue #1631171: Re-implement the 'warnings' module in C (the
6134 original Python code has been kept as backup). This will allow for
6135 using the 'warning's machinery in such places as the parser where
6136 use of pure Python code is not possible. Both the ``showarning()``
6137 and ``formatwarning()`` gain an optional 'line' argument which is
6138 not called by default for backwards-compatibility reasons. Setting
6139 ``warnings.showwarning()`` to an implementation that lacks support
6140 for the ``line`` argument will raise a DeprecationWarning.

6164
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00006165- The getpass module has been improved on Unix. It now uses /dev/tty
6166 by default and uses stderr instead of stdout. A GetPassWarning is
6167 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006203- Issue #2550: The approach used by client/server code for obtaining
6204 ports to listen on in network-oriented tests has been refined in an
6205 effort to facilitate running multiple instances of the entire
6206 regression test suite in parallel without issue.
6207 test_support.bind_port() has been fixed such that it will always
6208 return a unique port -- which wasn't always the case with the
6209 previous implementation, especially if socket options had been set
6210 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6211 new implementation of bind_port() will actually raise an exception
6212 if it is passed an AF_INET/SOCK_STREAM socket with either the
6213 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6214 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6215 the socket it's been passed. This currently only applies to
6216 Windows. This option prevents any other sockets from binding to the
6217 host/port we've bound to, thus removing the possibility of the
6218 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6219 when a second SOCK_STREAM socket binds and accepts to a host/port
6220 that's already been bound by another socket. The optional preferred
6221 port parameter to bind_port() has been removed. Under no
6222 circumstances should tests be hard coding ports!
6223
6224 test_support.find_unused_port() has also been introduced, which will
6225 pass a temporary socket object to bind_port() in order to obtain an
6226 unused port. The temporary socket object is then closed and
6227 deleted, and the port is returned. This method should only be used
6228 for obtaining an unused port in order to pass to an external program
6229 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6230 a parameter to a server-oriented class that doesn't give you direct
6231 access to the underlying socket used.
6232
6233 Finally, test_support.HOST has been introduced, which should be used
6234 for the host argument of any relevant socket calls (i.e. bind and
6235 connect).

6510-----------------
6511
Fred Drakea8ee94b2008-03-01 02:45:07 +00006512- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00006513 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00006514
Georg Brandlad61bc82008-02-23 15:11:18 +00006515- Issue #2067: file.__exit__() now calls subclasses' close() method.
6516
6517- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00006518
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006519- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00006520 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00006521
Eric Smitha73fbe72008-02-23 03:09:44 +00006522- Added the future_builtins module, which contains hex() and oct().
6523 These are the PEP 3127 version of these functions, designed to be
6524 compatible with the hex() and oct() builtins from Python 3.0. They
6525 differ slightly in their output formats from the existing, unchanged
6526 Python 2.6 builtins. The expected usage of the future_builtins
6527 module is:
6528 from future_builtins import hex, oct
6529
Eric Smith7ef40bf2008-02-20 23:34:22 +00006530- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6531 exponents for exponents with absolute value < 100. Follows C99
6532 standard. This is a change on Windows, which would use 3 digits.
6533 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6534 so that any alterations it does to the resulting string will be
6535 available in stringlib/formatter.h (for float.__format__).
6536
Eric Smith5a3c1352008-02-19 13:21:56 +00006537- Implemented PEP 3101, Advanced String Formatting. This adds a new
6538 builtin format(); a format() method for str and unicode; a
6539 __format__() method to object, str, unicode, int, long, float, and
6540 datetime; the class string.Formatter; and the C API
6541 PyObject_Format().
6542
Georg Brandl3ee81df2008-05-17 18:14:43 +00006543- Fixed several potential crashes, all caused by specially crafted
6544 __del__ methods exploiting objects in temporarily inconsistent
6545 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006546
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006547- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006548 prevent a possible crash: an Abstract Base Class would try to access
6549 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006550
Georg Brandl3ee81df2008-05-17 18:14:43 +00006551- Fixed repr() and str() of complex numbers with infinity or nan as
6552 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00006553
Georg Brandl3ee81df2008-05-17 18:14:43 +00006554- Clear all free lists during a gc.collect() of the highest generation
6555 in order to allow pymalloc to free more arenas. Python may give back
6556 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006557
Georg Brandl3ee81df2008-05-17 18:14:43 +00006558- Issue #2045: Fix an infinite recursion triggered when printing a
6559 subclass of collections.defaultdict, if its default_factory is set
6560 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006561
Christian Heimesf75dbef2008-02-08 00:11:31 +00006562- Fixed a minor memory leak in dictobject.c. The content of the free
6563 list was not freed on interpreter shutdown.
6564
Georg Brandl21e99f42010-03-07 15:23:59 +00006565- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006566 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006567
Georg Brandl3ee81df2008-05-17 18:14:43 +00006568- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6569 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006570 to compact the internal free lists of pre-allocted ints and floats.
6571
Georg Brandl3ee81df2008-05-17 18:14:43 +00006572- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6573 calls. Python expected the return type int but the fork familie
6574 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006575
Georg Brandl3ee81df2008-05-17 18:14:43 +00006576- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6577 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006578
Georg Brandl3ee81df2008-05-17 18:14:43 +00006579- Issue #2025: Add tuple.count() and tuple.index() methods to comply
6580 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00006581
Georg Brandl3ee81df2008-05-17 18:14:43 +00006582- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
6583 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00006584
Georg Brandl3ee81df2008-05-17 18:14:43 +00006585- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6586 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006587
Georg Brandl3ee81df2008-05-17 18:14:43 +00006588- Patch #1473257: generator objects gain a gi_code attribute. This is
6589 the same object as the func_code attribute of the function that
6590 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006591
Georg Brandl3ee81df2008-05-17 18:14:43 +00006592- Issue #1920: "while 0" statements were completely removed by the
6593 compiler, even in the presence of an "else" clause, which is
6594 supposed to be run when the condition is false. Now the compiler
6595 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006596
Guido van Rossumeead05f2008-01-24 18:21:02 +00006597- A few crashers fixed: weakref_in_del.py (issue #1377858);
6598 loosing_dict_ref.py (issue #1303614, test67.py);
6599 borrowed_ref_[34].py (not in tracker).
6600
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006601- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006602 suppressed while an extension is loaded by calling SetErrorMode in
6603 dynload_win.c. The error is still reported properly.
6604
Georg Brandl3ee81df2008-05-17 18:14:43 +00006605- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006606 several extension methods and modules do not work without unicode
6607 support.
6608
Georg Brandl26543b12008-01-21 18:36:51 +00006609- Issue #1882: when compiling code from a string, encoding cookies in the
6610 second line of code were not always recognized correctly.
6611
Georg Brandl14404b62008-01-19 19:27:05 +00006612- Issue #1679: "0x" was taken as a valid integer literal.
6613
Georg Brandl6caad7d2008-01-26 14:19:22 +00006614- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006615 added.
6616
Christian Heimesc94e2b52008-01-14 04:13:37 +00006617- sys.float_info / PyFloat_GetInfo: The floating point information
6618 object was converted from a dict to a specialized structseq object.
6619
Georg Brandl3ee81df2008-05-17 18:14:43 +00006620- Patch #1816: Added sys.flags structseq. It exposes the status of
6621 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006622
Georg Brandl3ee81df2008-05-17 18:14:43 +00006623- Objects/structseq.c: Implemented new structseq representation. The
6624 patch makes structseqs (e.g. the return value of os.stat) more
6625 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006626
Georg Brandl3ee81df2008-05-17 18:14:43 +00006627- Patch #1700288: added a type attribute cache that caches method
6628 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006629
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006630- Bug #1776: __import__() no longer accepts filenames on any platform.
6631 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006632
Georg Brandlaed6c662008-01-07 17:25:53 +00006633- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6634
Georg Brandl3ee81df2008-05-17 18:14:43 +00006635- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6636 envvar and sys.dont_write_bytecode attribute. All these can be set
6637 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006638
Georg Brandl3ee81df2008-05-17 18:14:43 +00006639- Improve some exception messages when Windows fails to load an
6640 extension module. Now we get for example '%1 is not a valid Win32
6641 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006642
Georg Brandl3ee81df2008-05-17 18:14:43 +00006643- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006645- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
6646 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006647
Christian Heimes0a8143f2007-12-18 23:22:54 +00006648- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006649 and INF. float("nan"), float("inf") and float("-inf") now work on
6650 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006651
Georg Brandl3ee81df2008-05-17 18:14:43 +00006652- Compiler now generates simpler and faster code for dictionary
6653 literals. The oparg for BUILD_MAP now indicates an estimated
6654 dictionary size. There is a new opcode, STORE_MAP, for adding
6655 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00006656
Georg Brandl3ee81df2008-05-17 18:14:43 +00006657- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006662- Issue #1538: Avoid copying string in split/rsplit if the split char
6663 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00006664
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00006665- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00006666 SystemError.
6667
Nick Coghlanef01d822007-12-03 12:55:17 +00006668- PEP 366: Allow explicit relative imports when executing modules
6669 inside packages with the -m switch via a new module level
6670 __package__ attribute.
6671
Georg Brandl3ee81df2008-05-17 18:14:43 +00006672- Issue #1402: Fix a crash on exit, when another thread is still
6673 running, and if the deallocation of its frames somehow calls the
6674 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00006675

6685 file can now be directly executed by passing their name to the
6686 interpreter. The directory/zipfile is automatically inserted as the
6687 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006688
Georg Brandl3ee81df2008-05-17 18:14:43 +00006689- Issue #1265: Fix a problem with sys.settrace, if the tracing
6690 function uses a generator expression when at the same time the
6691 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006692
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006693- sets and frozensets now have an isdisjoint() method.
6694
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006695- optimize the performance of builtin.sum().
6696
Neal Norwitz44f326e2007-10-05 05:29:17 +00006697- Fix warnings found by the new version of the Coverity checker.
6698
Georg Brandl21e99f42010-03-07 15:23:59 +00006699- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006700 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6701 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006702
Georg Brandl3ee81df2008-05-17 18:14:43 +00006703- Issue #1686386: Tuple's tp_repr did not take into account the
6704 possibility of having a self-referential tuple, which is possible
6705 from C code. Nor did object's tp_str consider that a type's tp_str
6706 could do something that could lead to an inifinite recursion.
6707 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6708 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006709
Georg Brandl3ee81df2008-05-17 18:14:43 +00006710- Issue #1164: It was possible to trigger deadlock when using the
6711 'print' statement to write to a file since the GIL was not released
6712 as needed. Now PyObject_Print() does the right thing along with
6713 various tp_print implementations of the built-in types and those in
6714 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006715
Georg Brandl3ee81df2008-05-17 18:14:43 +00006716- Issue #1147: Exceptions were directly allowing string exceptions in
6717 their throw() method even though string exceptions no longer
6718 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006719

Brett Cannon1e534b52007-09-07 04:18:30 +00006723- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006724 PyObject_Call() never calling back out to Python code to trigger
6725 recursion depth updates/checks. Required the creation of a static
6726 RuntimeError instance in case normalizing an exception put the

Georg Brandl3ee81df2008-05-17 18:14:43 +00006744 __*__ attributes. (Some already existed, e.g., __doc__ and
6745 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006746

6755 with Python 3.0.

Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006763 setting a plain string, ie don't expand to single letter identifiers.
6764
Raymond Hettinger13936692007-04-11 18:40:58 +00006765- Request #1191699: Slices can now be pickled.

6775
Guido van Rossum143b5642007-03-23 04:58:42 +00006776- Bug #1683368: The object.__init__() and object.__new__() methods are
6777 now stricter in rejecting excess arguments. The only time when
6778 either allows excess arguments is when it is not overridden and the
6779 other one is. For backwards compatibility, when both are
6780 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006781 warning later). Also, type.__init__() insists on the same signature
6782 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006783
Georg Brandl3ee81df2008-05-17 18:14:43 +00006784- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6785 object to complex using its __complex__() method before falling back
6786 to the __float__() method. Therefore, the functions in the cmath
6787 module now can operate on objects that define a __complex__()
6788 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00006806- Bug #1678647: write a newline after printing an exception in any
6807 case, even when converting the value to a string failed.
6808
Georg Brandl871f1bc2007-03-12 13:17:36 +00006809- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006810 its argument, if it exists. If not, it will work like before. This
6811 allows customizing the output of dir() in the presence of a
6812 __getattr__().

6822 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006823
Georg Brandlaa2321b2007-03-07 00:40:28 +00006824- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006825 makes the filenames the warning module prints much more sensible
6826 when a PYTHONSTARTUP file is used.

6840 sq_ass_slice instead of the sq_slice slot.
6841
Georg Brandl3ee81df2008-05-17 18:14:43 +00006842- When printing an unraisable error, don't print exceptions. before

7470 accepted in TestSuite.addTest(). This should cause no
7471 incompatibility since it never made sense with ordinary subclasses
7472 -- the failure just occurred later, with a more cumbersome
7473 exception.

7757 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007758
Georg Brandl3ee81df2008-05-17 18:14:43 +00007759- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007760 that the SMTP.starttls() caller no longer needs to call ehlo()
7761 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007762 does not claim to support starttls. Adds the
7763 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

7844 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7845 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00007862 time so that opening a database previously created with the DB_DUP
7863 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7864 opens. Specifically: dictionary assignment to a DB object will
7865 replace all values for a given key when the database allows
7866 duplicate values. DB users should use DB.put(k, v) when they want
7867 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007868

7874 characters with ASCII value less than 32. Also, it correctly quotes
7875 dots only if they occur on a single line, as opposed to the previous
7876 behavior of quoting dots if they are the second character of any
7877 line.

8200-----
8201
Georg Brandl3ee81df2008-05-17 18:14:43 +00008202- Unified naming convention for free lists and their limits. All free
8203 lists in Object/ are named ``free_list``, the counter ``numfree``
8204 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
8205 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00008206
Georg Brandl3ee81df2008-05-17 18:14:43 +00008207- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8208 to ``PyTuple_SetItem``, it can be used to populate a brand new
8209 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00008210
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008211- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00008212
Georg Brandl3ee81df2008-05-17 18:14:43 +00008213- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
8214 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
8215 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008216
8217- Patch #1720595: add T_BOOL to the range of structmember types.
8218
8219- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
8220 ``PyFloat_GetInfo()`` to the float API.
8221
Georg Brandl3ee81df2008-05-17 18:14:43 +00008222- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8223 of w# format code incorrectly truncated the length to an int, even
8224 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8225 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008226
Georg Brandl3ee81df2008-05-17 18:14:43 +00008227- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
8228 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008229
Georg Brandl3ee81df2008-05-17 18:14:43 +00008230- PEP 3123: Provide forward compatibility with Python 3.0, while
8231 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
8232 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008233
Georg Brandl3ee81df2008-05-17 18:14:43 +00008234- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
8235 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008236
8237- Patch #1733960: Allow T_LONGLONG to accept ints.
8238
8239- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
8240
Christian Heimes000a0742008-01-03 22:16:32 +00008241- Added a new API function ``PyImport_ImportModuleNoBlock``.
8242
Georg Brandl6caad7d2008-01-26 14:19:22 +00008243- Bug #1637022: Prefix AST symbols with _Py_.
8244
8245- Fix some leftovers from the conversion from int to Py_ssize_t
8246 (relevant to strings and sequences of more than 2**31 items).
8247
8248- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8249 outside of pystate.c and should not be necessary.
8250
Georg Brandl3ee81df2008-05-17 18:14:43 +00008251- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8252 absolute imports. In earlier versions they might have used relative
8253 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008254
Georg Brandl3ee81df2008-05-17 18:14:43 +00008255- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8256 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008257
Georg Brandl3ee81df2008-05-17 18:14:43 +00008258- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
8259 macro so it can be used as an expression.

8264
Georg Brandl3ee81df2008-05-17 18:14:43 +00008265- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
8266 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
8267 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
8268 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00008269
Georg Brandl3ee81df2008-05-17 18:14:43 +00008270- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
8271 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008283- Removed the macfs module. It had been deprecated since Python 2.5.
8284 This lead to the deprecation of macostools.touched() as it relied
8285 solely on macfs and was a no-op under OS X.
