389 int.__pow__. These overflow checks were causing int.__pow__ to produce
390 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100391 compiler optimizing the check away. Also fix similar overflow checks
392 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

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

Florent Xiclunac2279652012-02-12 14:49:03 +0100461- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100462 has left two versions of customize_compiler, the original in
463 distutils.sysconfig and another copy in distutils.ccompiler, with some

467
Ned Deily0d0ea482012-02-10 12:59:06 +0100468- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
469 Distutils-based packages with C extension modules may fail because
470 Apple has removed gcc-4.2, the version used to build python.org
471 64-bit/32-bit Pythons. If the user does not explicitly override
472 the default C compiler by setting the CC environment variable,
473 Distutils will now attempt to compile extension modules with clang
474 if gcc-4.2 is required but not found. Also as a convenience, if
475 the user does explicitly set CC, substitute its value as the default
476 compiler in the Distutils LDSHARED configuration variable for OS X.
477 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
478 SDK, neither of which are available in Xcode 4. This change does not
479 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700752- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
753 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
754 interpreter process. This could cause failures in non-Distutils subprocesses
755 and was unreliable since tests or user programs could modify the interpreter
756 environment after Distutils set it. Instead, have Distutils set the the
757 deployment target only in the environment of each build subprocess. It is
758 still possible to globally override the default by setting
759 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
760 greater or equal to the default value, the value with which the interpreter
761 was built.

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

1746 GC collection rather than freeing memory immediately when the refcnt drops

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002206- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2207 start byte and the continuation byte(s) are now considered invalid, instead
2208 of the number of bytes specified by the start byte.
2209 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2210 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2211 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

2221 objects. (1) The comparison could incorrectly return True in some cases
2222 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2223 (2) The comparison raised an OverflowError for large integers, leading

2365 non-float non-integer argument is now converted to an integer (if possible)
2366 using its __int__ method. Previously, only small arguments were treated this
2367 way; larger arguments (those whose __int__ was outside the range of a C long)

2419 operation raises multiple signals and more than one of those signals is
2420 trapped, the specification determines the order in which the signals should be
2421 handled. In many cases this order wasn't being followed, leading to the wrong

Georg Brandlfee0f442010-05-22 21:26:21 +00002566- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002567 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
2568 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
2569 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

2589Core and Builtins
2590-----------------
2591
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002592- Issue #7301: Add environment variable $PYTHONWARNINGS.
2593
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002594- Issue #8329: Don't return the same lists from select.select when no fds are
2595 changed.
2596
Georg Brandlfee0f442010-05-22 21:26:21 +00002597- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002598 on 64-bit machines. The shift count for either left or right shift is
2599 permitted to be up to sys.maxsize.
2600
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002601- Ensure that tokenization of identifiers is not affected by locale.
2602
Georg Brandlfee0f442010-05-22 21:26:21 +00002603- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002604
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002605- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2606
Georg Brandlfee0f442010-05-22 21:26:21 +00002607- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2608 with a non-empty format string. This is an effort to future-proof user
2609 code. If a derived class does not currently implement __format__ but later
2610 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002611 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002612 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002613
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002614- Issue #8268: Old-style classes (not just instances) now support weak
2615 references.
2616
Georg Brandlfee0f442010-05-22 21:26:21 +00002617- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
2618 is set.

2626
Victor Stinner66644262010-03-10 22:30:19 +00002627- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002628 (SIGINT). If an error occurs while importing the site module, the error is
2629 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00002630 module.

Antoine Pitrouf9de5342010-04-05 21:35:07 +00002639- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00002640 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and

Benjamin Peterson76a23c12010-04-04 23:23:22 +00002643- Issue #8310: Allow dis to examine new style classes.
2644
Georg Brandlfee0f442010-05-22 21:26:21 +00002645- Issue #8257: The Decimal construct now accepts a float instance directly,
2646 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002647
2648 >>> Decimal(1.1)
2649 Decimal('1.100000000000000088817841970012523233890533447265625')
2650
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002651- collections.Counter() now supports a subtract() method.
2652
Georg Brandlfee0f442010-05-22 21:26:21 +00002653- The functools module now has a total_ordering() class decorator to simplify
2654 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002655
Georg Brandlfee0f442010-05-22 21:26:21 +00002656- The functools module also adds cmp_to_key() as a tool to transition old-style
2657 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002658
Georg Brandlfee0f442010-05-22 21:26:21 +00002659- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2660 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002661
Georg Brandlfee0f442010-05-22 21:26:21 +00002662- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2663 InvalidOperation instead of returning False. (Comparisons involving a quiet
2664 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2665 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002666
Georg Brandlfee0f442010-05-22 21:26:21 +00002667- Issue #2531: Comparison operations between floats and Decimal instances now
2668 return a result based on the numeric values of the operands; previously they
2669 returned an arbitrary result based on the relative ordering of id(float) and
2670 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002671
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002672- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002673 argument `-` which tells it to read files to compile from stdin. Each line is
2674 read on demand and the named file is compiled immediately. (Original patch by
2675 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002676
Georg Brandlfee0f442010-05-22 21:26:21 +00002677- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
2678 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00002680- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2681 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002682 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002683
Georg Brandlfee0f442010-05-22 21:26:21 +00002684- Comparisons using one of <, <=, >, >= between a complex instance and a
2685 Fractions instance now raise TypeError instead of returning True/False. This
2686 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2687 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00002688

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002698- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00002699 didn't support chflags() (for example ZFS under FreeBSD). The error is now
2700 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002701
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00002702- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
2703 deprecated.
2704
Georg Brandlfee0f442010-05-22 21:26:21 +00002705- Issue #7860: platform.uname now reports the correct 'machine' type when Python

Vinay Sajipecfa08f2010-03-12 09:16:10 +00002742- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00002743 for ``TimedRotatingFileHandler`` by using the modification time of an existing
2744 log file to compute the next rollover time. If the log file does not exist,
2745 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00002746

Georg Brandlba83f822010-03-14 09:50:54 +00002755- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
2756 a base64 transfer-encoded payload *after* decoding it; it no longer does.
2757 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +00002786- Issue #8300: When passing a non-integer argument to struct.pack with any
2787 integer format code, struct.pack first attempts to convert the non-integer
2788 using its __index__ method. If that method is non-existent or raises
2789 TypeError it goes on to try the __int__ method, as described below.
2790
Georg Brandlba83f822010-03-14 09:50:54 +00002791- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2792 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2793 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002794 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2795 inconsistent: __int__ was used for some integer codes but not for others, and
2796 the set of integer codes for which it was used differed between native packing

3029 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00003030 library would return a bogus result; on Solaris, it was possible to crash the

Georg Brandlba83f822010-03-14 09:50:54 +00003049- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
3050 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3051 returning NULL. The macro now returns a statically allocated empty string
3052 instead.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003104- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003105 file position when calling `truncate()`. It would previously change the file
3106 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003107 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

3110 class used to represent files stored inside an archive. The new
3111 implementation is significantly faster and can be wrapped in a
3112 ``io.BufferedReader`` object for more speedups. It also solves an issue
3113 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00003124- Issue #7748: Since unicode values are supported for some metadata options in
3125 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3126 encoded string for them. This ensures that the upload and register commands
3127 send the correct values to PyPI without any error.

3202-----------------
3203
Georg Brandlba83f822010-03-14 09:50:54 +00003204- The ``__complex__()`` method is now looked up on the class of instances to
3205 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00003207- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
3208 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
3209
Mark Dickinson1b34d252010-01-01 17:27:30 +00003210- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003211 DeprecationWarning when passed a float argument where an integer was expected.
3212 These functions and methods now raise TypeError instead. The majority of the
3213 effects of this change are in the extension modules, but some core functions
3214 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3215 and many unicode/str methods.

3229 of integers: the result of a/b is now correctly rounded for ints a and b (at
3230 least on IEEE 754 platforms), and in particular does not depend on the
3231 internal representation of a long.

3239
Georg Brandlba83f822010-03-14 09:50:54 +00003240 These executables now work properly with the arch(1) command: ``arch -ppc
3241 python`` will start a universal binary version of python in PPC mode (unlike
3242 previous releases).

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003383

3385 1e50 in absolute value.

Georg Brandlba83f822010-03-14 09:50:54 +00003398- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3399 decimal string that's guaranteed to round back to x under correct rounding
3400 (with round-half-to-even rounding mode). Previously it gave a string based on
3401 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3402 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3403 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003404
Georg Brandlba83f822010-03-14 09:50:54 +00003405- Issue #7117: On almost all platforms: float-to-string and string-to-float
3406 conversions within Python are now correctly rounded. Places these conversions
3407 occur include: str for floats and complex numbers; the float and complex
3408 constructors; old-style and new-style numeric formatting; serialization and
3409 deserialization of floats and complex numbers using marshal, pickle and json;
3410 parsing of float and imaginary literals in Python code; Decimal-to-float
3411 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003412
Georg Brandlba83f822010-03-14 09:50:54 +00003413 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3414 providing correctly-rounded strtod and dtoa C functions. This code is
3415 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3416 the C compiler. There may be a small number of platforms on which correct
3417 operation of this code cannot be guaranteed, so the code is not used: notably,
3418 this applies to platforms where the C double format is not IEEE 754 binary64,
3419 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3420 and Python's configure script is unable to determine how to change the FPU
3421 precision. On these platforms conversions use the platform strtod and dtoa,
3422 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003424- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3425 uses the correctly-rounded string <-> float conversions described above (when
3426 available), and so produces correctly rounded results that will display nicely
3427 under the float repr. There are two related small changes: (1) round now
3428 accepts any class with an ``__index__()`` method for its second argument (but
3429 no longer accepts floats for the second argument), and (2) an excessively
3430 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3431 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00003573
Georg Brandlba83f822010-03-14 09:50:54 +00003574 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3575 (2) parsing of strings representing infinities and nans was locale aware; and
3576 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00003578- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3579 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3580 but with at least one decimal point and with a default precision
3581 of 12. Previously, the behavior the same but with a default precision of 6.
3582 This more closely matches ``str()``, and reduces surprises when adding
3583 alignment flags to the empty presentation type. This also affects the new
3584 complex.__format__ in the same way.
3585
3586- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Benjamin Peterson7af65562008-12-29 17:56:58 +00003741- Issue #4764: With io.open, IOError.filename is set when trying to open a

3746
Georg Brandl6425a2f2008-12-28 11:54:53 +00003747- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00003748 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00003749
Skip Montanarof205c132008-12-23 03:30:15 +00003750- Added test case to ensure attempts to read from a file opened for writing
3751 fail.
3752
Georg Brandlba83f822010-03-14 09:50:54 +00003753- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
3754 elapsed times, not only when some objects are uncollectable/unreachable.
3755 Original patch by Neil Schemenauer.

Georg Brandlba83f822010-03-14 09:50:54 +00003767- Issue #4445: Replace ``sizeof(PyStringObject)`` with
3768 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
3769 instances. On a typical machine this saves 3 bytes of memory (on average) per
3770 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00003772- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
3773 interpreter to abort ("Fatal Python error: Could not reset the stack!")
3774 instead of throwing a MemoryError.
3775
Georg Brandlba83f822010-03-14 09:50:54 +00003776- Issue #3689: The list reversed iterator now supports __length_hint__ instead
3777 of __len__. Behavior now matches other reversed iterators.

Benjamin Petersonc078f922008-11-21 22:27:24 +00003779- Issue #4367: Python would segfault during compiling when the unicodedata
3780 module couldn't be imported and \N escapes were present.
3781
Georg Brandlba83f822010-03-14 09:50:54 +00003782- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3783 file objects with closefd=False. The file descriptor is still kept open but
3784 the file object behaves like a closed file. The ``FileIO`` object also got a
3785 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00003786
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00003787- Issue #4348: Some bytearray methods returned that didn't cause any change to
3788 the bytearray, returned the same bytearray instead of a copy.
3789
Georg Brandlba83f822010-03-14 09:50:54 +00003790- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Petersondcee09d2008-10-31 02:16:05 +00003796- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

Benjamin Petersonbdca9422008-10-26 20:21:13 +00003802- Issue #4209: Enabling unicode_literals and the print_function in the same
3803 __future__ import didn't work.
3804
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003805- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00003806 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003807
Georg Brandlba83f822010-03-14 09:50:54 +00003808- On windows, ``os.chdir()`` given unicode was not working if
3809 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3810 this code path is really executed because I cannot move to such directory on
3811 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00003812
Georg Brandlba83f822010-03-14 09:50:54 +00003813- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3814 element is temporarily replaced with an equivalent frozenset. But the
3815 eventual KeyError would always report the empty ``frozenset()`` as the missing
3816 key. Now it correctly refers to the initial element.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +00003833- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
3834 returned them on 64bit platforms.
3835
Walter Dörwalded960ac2009-05-03 22:36:33 +00003836- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3837 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3838 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3839 of using the replace error handler in PyUnicode_DecodeUTF8().
3840
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003841- Issue #3739: The unicode-internal encoder now reports the number of characters
3842 consumed like any other encoder (instead of the number of bytes).
3843
Georg Brandlba83f822010-03-14 09:50:54 +00003844- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3845 allocator will be automatically disabled when running under Valgrind. This
3846 gives improved memory leak detection when running under Valgrind, while taking
3847 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00005091 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
5092 the tests if DISPLAY is defined but can't be used.

Antoine Pitrou4698d992009-05-31 14:20:14 +00005094- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
5095 regression tests in parallel, shortening the total runtime.
5096
Georg Brandlba83f822010-03-14 09:50:54 +00005097- Issue #5354: New test support function import_fresh_module() makes it easy to
5098 import both normal and optimised versions of modules. test_heapq and
5099 test_warnings have been adjusted to use it, tests for other modules with both
5100 C and Python implementations in the stdlib can be adjusted to use it over
5101 time.

5110 should cause a test to be skipped are now done using import_module from test
5111 support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005212- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5213
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005214- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5215 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5216 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5217 ``printf`` function, whereas PyString_FromFormat has an independent
5218 implementation and uses "%zd" on all platforms for size_t values.
5219 This makes a difference on win64, where ``printf`` needs "%Id" to display
5220 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00005222- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

5226 object; previously an int would be returned for small values. the __long__
5227 method is allowed to return either an int or a long, but the behaviour of
5228 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005230- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00005236 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005237 was correctly parsed but parsing of subsequent arguments failed.
5238
Vinay Sajip35e3b032008-09-01 14:33:59 +00005239- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005240 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5241 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5242 when given a tuple of classes as second argument, were looking up
5243 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5244 type object.
5245
Neal Norwitz18aa3882008-08-24 05:04:52 +00005246- Fix crashes on memory allocation failure found with failmalloc.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005383What's New in Python 2.6 beta 3?
5384================================
5385
Barry Warsaw07a4a382008-08-21 01:15:08 +00005386*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005387
5388Core and Builtins
5389-----------------
5390
Guido van Rossumf8402962008-08-20 15:01:50 +00005391- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5392 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5393 extensions do not automatically benefit from the class attribute
5394 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5395 to their tp_flags field if they care. This is a backwards
5396 compatibility feature; in 3.0, all types will use the cache by
5397 default.
5398
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005399- Keyword arguments can now follow starred arguments. (``f(a, *args,
5400 keyword=23)`` is now valid syntax.)
5401
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005402- ctypes function pointers that are COM methods have a boolean True
5403 value again.
5404
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005405- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5406 by denying s# to parse objects that have a releasebuffer procedure,
5407 and introducing s*.
5408
Georg Brandl1e13ea92008-08-11 09:07:59 +00005409- Issue #3537: Fix an assertion failure when an empty but presized dict
5410 object was stored in the freelist.
5411
Mark Dickinsonb6467572008-08-04 21:30:09 +00005412- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5413 ValueError consistently across platforms.
5414
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005415- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5416 (64bit Unix, for example), unichr() would truncate its argument and return
5417 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5418
Neal Norwitze7d8be82008-07-31 17:17:14 +00005419- Apply security patches from Apple.
5420
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005421- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5422 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5423
Antoine Pitrou92f82162008-07-25 22:22:08 +00005424- Issue #1819: function calls with several named parameters are now on
5425 average 35% faster (as measured by pybench).
5426
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005427- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5428 the python debugger steps into a class statement: the free variables (local
5429 variables defined in an outer scope) would be deleted from the outer scope.
5430
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005431- Issue #2620: Overflow checking when allocating or reallocating memory
5432 was not always being done properly in some python types and extension
5433 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5434 all been updated to perform better checks and places in the code that
5435 would previously leak memory on the error path when such an allocation
5436 failed have been fixed.
5437
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005438Library
5439-------
5440
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005441- Issue #3612: Added some missing basic types in ctypes.wintypes.
5442
Benjamin Petersone977ad42008-08-20 01:42:01 +00005443- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5444 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5445
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005446- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5447 version reported by these tools does not necessarily follow the python
5448 version numbering scheme, so the module is less strict when parsing it.
5449
Nick Coghlanf70385a2008-08-18 12:42:46 +00005450- Issue #2235: Added Py3k warnings for types which will become unhashable
5451 under the stricter __hash__ inheritance rules in 3.0. Several types
5452 which did not meet the rules for hash invariants and were already
5453 unhashable in 3.0 have now been explicitly flagged as unhashable in
5454 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5455 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5456
Brett Cannon88f801d2008-08-18 00:46:22 +00005457- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5458 imported into the module but exposed as part of the module's API.
5459
Brett Cannon7b96f072008-08-18 00:41:11 +00005460- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5461
Brett Cannon46225e72008-08-18 00:36:52 +00005462- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
5463
Brett Cannon25c9d6a2008-08-17 22:10:11 +00005464- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5465
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005466- Issue #3575: Incremental decoder's decode function now takes bytearray
5467 by using 's*' instead of 't#'.
5468
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005469- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005470 fails unicode conversion on 2nd parameter. (windows only)
5471
Georg Brandl222e2082010-08-01 22:27:39 +00005472- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005473 in a redirect.
5474
Brett Cannonabe423e2008-08-16 21:47:07 +00005475- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005476 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005477
Facundo Batistaeb90b782008-08-16 14:44:07 +00005478- Issue #2776: fixed small issue when handling an URL with double slash
5479 after a 302 response in the case of not going through a proxy.
5480
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005481- Issue #2676: in the email package, content-type parsing was hanging on
5482 pathological input because of quadratic or exponential behaviour of a
5483 regular expression.
5484
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005485- Issue #3476: binary buffered reading through the new "io" library is now
5486 thread-safe.
5487
Brett Cannonbf3157b2008-08-14 05:00:03 +00005488- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5489 since mimetools itself is deprecated. Because modules are cached, all
5490 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5491
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005492- Issue #3134: shutil referenced undefined WindowsError symbol.
5493
Robert Schuppenies14646332008-08-10 11:01:53 +00005494- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5495 menu entries were not deleted.
5496
Brett Cannon83e81842008-08-09 23:30:55 +00005497- Copied the implementation of reduce() to _functools.reduce() to have a
5498 version that did not raise a DeprecationWarning under -3.
5499
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005500- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5501 a MemoryError rather than silently stop the iteration.
5502
Guido van Rossum59ce9012008-08-09 14:55:34 +00005503- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5504 to _sre.compile() will now be rejected. This should not affect anybody
5505 since the re.compile() function never generates invalid re-bytecode.
5506
Skip Montanaroa032bf42008-08-08 22:52:51 +00005507- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5508 upon first access it can be automatically initialized from the csv file if
5509 it wasn't initialized during instantiation.
5510
Brett Cannon3aa2a492008-08-06 22:28:09 +00005511- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5512 the reload() built-in has been removed.
5513
Brett Cannon7e30b672008-08-04 21:52:25 +00005514- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005515 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00005516 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
5517 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
5518 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
5519 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
5520 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00005521
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00005522- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
5523 raised an AttributeError.
5524
Benjamin Peterson01a24322008-07-28 23:35:27 +00005525- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00005526 asking for a specific length. This problem only affected files opened
5527 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005528
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00005529- Issue #3449: Update decimal module to use most recent specification
5530 (v. 1.68) and tests (v. 2.58) from IBM.
5531
Georg Brandl222e2082010-08-01 22:27:39 +00005532- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00005533

Raymond Hettinger8c664e82008-07-25 18:43:33 +00005535 on a closed shelf.
5536
Georg Brandlf9efabb2008-07-23 15:16:45 +00005537- Deprecate the "ast" parser function aliases.
5538
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005539- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
5540
5541- Issue #3303: Fix a crash in locale.strcoll() when calling it with
5542 invalid arguments.
5543
5544- Issue #3302: Fix several crashes when calling locale's gettext functions
5545 with None arguments.
5546
5547- Issue #3389: Allow resolving dotted names for handlers in logging
5548 configuration files.
5549

5551
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005552- Issue #3394: zipfile.writestr sets external attributes when passed a
5553 file name rather than a ZipInfo instance, so files are extracted with
5554 mode 0600 rather than 000 under Unix.
5555
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005556- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5557 argument in python 2.5, this broke code that subclassed Popen to include its
5558 own poll method. Fixed my moving _deadstate to an _internal_poll method.
5559
Martin v. Löwis8dbf3642008-08-01 14:10:26 +00005560Build
5561-----

5566-------------
5567
Nick Coghlan6e8fef02008-08-18 13:14:22 +00005568- Issue #2235: the C API function PyObject_HashNotImplemented and its
5569 interaction with the tp_hash slot (added in 2.6b2) are now documented
5570
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005571- Issue #643841: The language reference now provides more detailed
5572 coverage of the lookup process for special methods. The disclaimers
5573 regarding lack of coverage of new-style classes have also been
5574 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005577What's New in Python 2.6 beta 2?
5578================================
5579
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005580*Release date: 17-Jul-2008*
5581
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005582Core and Builtins
5583-----------------
5584
Georg Brandl3e483f62008-07-16 22:57:41 +00005585- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5586 its methods now allow for items objects that can be converted to
5587 an integer using operator.index().
5588
Mark Dickinson64b7e502008-07-16 09:40:03 +00005589- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5590 produced a ValueError instead of giving the correct float.
5591
Eric Smitha5fa5a22008-07-16 00:11:49 +00005592- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5593 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5594
Mark Dickinson7103aa42008-07-15 19:08:33 +00005595- Issue #3008: the float type has a new instance method 'float.hex'
5596 and a new class method 'float.fromhex' to convert floating-point
5597 numbers to and from hexadecimal strings, respectively.
5598
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005599- Issue #2235: __hash__ is once again inherited by default. To allow
5600 collections.Hashable to remain meaningful in the presence of the
5601 default hash implementation (object.__hash__), it is now possible
5602 to explicit block inheritance of hash by setting __hash__=None at
5603 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5604 level.
5605
Nick Coghlanb028f502008-07-13 14:52:36 +00005606- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5607 the parent module cannot be found while performing an absolute import.
5608 This means that an incorrectly defined __package__ attribute will
5609 now only prevent relative imports in that module rather than causing
5610 all imports from that module to fail.
5611
Nick Coghlan14ff9942008-07-08 14:21:42 +00005612- Issue #2517: Allow unicode messages in Exceptions again by correctly
5613 bypassing the instance dictionary when looking up __unicode__ on
5614 new-style classes.
5615
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005616- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5617 set to a custom object whose write() method happens to install
5618 another file in sys.stdout.
5619
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005620- Issue #3088: Corrected a race condition in classes derived from
5621 threading.local: the first member set by a thread could be saved in
5622 another thread's dictionary.
5623
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005624- Issue #3004: Minor change to slice.indices(): the start and stop
5625 arguments are now treated identically, making the behaviour easier
5626 to describe and understand. For example, slice(None, -10,
5627 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5628 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5629 10, -1).
5630
Georg Brandl278fc502008-07-19 12:46:12 +00005631- Issue #3219: Calling a function with repeated keyword arguments,
5632 f(a=2, a=23), would not cause a syntax error. This was a regression
5633 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005634
Georg Brandl278fc502008-07-19 12:46:12 +00005635- Issue #2862: Make int and float freelist management consistent with
5636 other freelists. Changes their CompactFreeList apis into
5637 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00005638

5640-------
5641
Thomas Heller57adf222008-08-14 19:10:48 +00005642- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5643 api functions without holding the GIL, which could lead to a fatal
5644 error when they failed.
5645
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005646- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

5655 ForkingPickler.register() to resolve conflict with ctypes.
5656
Vinay Sajip51e65192008-07-18 09:01:10 +00005657- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

5660 a valid dlerror() message.
5661
Thomas Heller2bad6572008-07-15 17:19:50 +00005662- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5663 incomplete structure was created.

Raymond Hettingerb01713e2008-07-10 14:34:57 +00005667- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
5668

6080
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006081- On MacOS X it is now possible to install the framework in 64-bit
6082 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006083 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006084
6085 This is controlled by the configure argument ``--with-universal-archs``:
6086
6087 - ``--with-universal-archs=all``: install 4-way universal
6088
6089 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6090
6091 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6092
6093 This option should be used in combination with ``--enable-universalsdk=``.
6094
6095 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 +00006131- Issue #2670: Fix a failure in urllib2.build_opener(), when passed
6132 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00006133
Christian Heimese74c8f22008-04-19 02:23:57 +00006134- Added kill, terminate and send_signal(sig) to subprocess.Popen.
6135
Georg Brandl3ee81df2008-05-17 18:14:43 +00006136- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
6137 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00006138
Georg Brandl3ee81df2008-05-17 18:14:43 +00006139- Four new methods were added to the math and cmath modules: acosh,

Georg Brandl3ee81df2008-05-17 18:14:43 +00006145- Issue #1631171: Re-implement the 'warnings' module in C (the
6146 original Python code has been kept as backup). This will allow for
6147 using the 'warning's machinery in such places as the parser where
6148 use of pure Python code is not possible. Both the ``showarning()``
6149 and ``formatwarning()`` gain an optional 'line' argument which is
6150 not called by default for backwards-compatibility reasons. Setting
6151 ``warnings.showwarning()`` to an implementation that lacks support
6152 for the ``line`` argument will raise a DeprecationWarning.

6176
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00006177- The getpass module has been improved on Unix. It now uses /dev/tty
6178 by default and uses stderr instead of stdout. A GetPassWarning is
6179 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00006180

Georg Brandl3ee81df2008-05-17 18:14:43 +00006194- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00006195 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00006215- Issue #2550: The approach used by client/server code for obtaining
6216 ports to listen on in network-oriented tests has been refined in an
6217 effort to facilitate running multiple instances of the entire
6218 regression test suite in parallel without issue.
6219 test_support.bind_port() has been fixed such that it will always
6220 return a unique port -- which wasn't always the case with the
6221 previous implementation, especially if socket options had been set
6222 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6223 new implementation of bind_port() will actually raise an exception
6224 if it is passed an AF_INET/SOCK_STREAM socket with either the
6225 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6226 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6227 the socket it's been passed. This currently only applies to
6228 Windows. This option prevents any other sockets from binding to the
6229 host/port we've bound to, thus removing the possibility of the
6230 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6231 when a second SOCK_STREAM socket binds and accepts to a host/port
6232 that's already been bound by another socket. The optional preferred
6233 port parameter to bind_port() has been removed. Under no
6234 circumstances should tests be hard coding ports!
6235
6236 test_support.find_unused_port() has also been introduced, which will
6237 pass a temporary socket object to bind_port() in order to obtain an
6238 unused port. The temporary socket object is then closed and
6239 deleted, and the port is returned. This method should only be used
6240 for obtaining an unused port in order to pass to an external program
6241 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6242 a parameter to a server-oriented class that doesn't give you direct
6243 access to the underlying socket used.
6244
6245 Finally, test_support.HOST has been introduced, which should be used
6246 for the host argument of any relevant socket calls (i.e. bind and
6247 connect).

6252 test_asynchat and test_socket_ssl.
6253

6255 suite to run in parallel without issue.

6522-----------------
6523
Fred Drakea8ee94b2008-03-01 02:45:07 +00006524- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00006525 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00006526
Georg Brandlad61bc82008-02-23 15:11:18 +00006527- Issue #2067: file.__exit__() now calls subclasses' close() method.
6528
6529- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00006530
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006531- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00006532 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00006533
Eric Smitha73fbe72008-02-23 03:09:44 +00006534- Added the future_builtins module, which contains hex() and oct().
6535 These are the PEP 3127 version of these functions, designed to be
6536 compatible with the hex() and oct() builtins from Python 3.0. They
6537 differ slightly in their output formats from the existing, unchanged
6538 Python 2.6 builtins. The expected usage of the future_builtins
6539 module is:
6540 from future_builtins import hex, oct
6541
Eric Smith7ef40bf2008-02-20 23:34:22 +00006542- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6543 exponents for exponents with absolute value < 100. Follows C99
6544 standard. This is a change on Windows, which would use 3 digits.
6545 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6546 so that any alterations it does to the resulting string will be
6547 available in stringlib/formatter.h (for float.__format__).
6548
Eric Smith5a3c1352008-02-19 13:21:56 +00006549- Implemented PEP 3101, Advanced String Formatting. This adds a new
6550 builtin format(); a format() method for str and unicode; a
6551 __format__() method to object, str, unicode, int, long, float, and
6552 datetime; the class string.Formatter; and the C API
6553 PyObject_Format().
6554
Georg Brandl3ee81df2008-05-17 18:14:43 +00006555- Fixed several potential crashes, all caused by specially crafted
6556 __del__ methods exploiting objects in temporarily inconsistent
6557 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006558
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006559- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006560 prevent a possible crash: an Abstract Base Class would try to access
6561 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006562
Georg Brandl3ee81df2008-05-17 18:14:43 +00006563- Fixed repr() and str() of complex numbers with infinity or nan as
6564 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00006565
Georg Brandl3ee81df2008-05-17 18:14:43 +00006566- Clear all free lists during a gc.collect() of the highest generation
6567 in order to allow pymalloc to free more arenas. Python may give back
6568 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006569
Georg Brandl3ee81df2008-05-17 18:14:43 +00006570- Issue #2045: Fix an infinite recursion triggered when printing a
6571 subclass of collections.defaultdict, if its default_factory is set
6572 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006573
Christian Heimesf75dbef2008-02-08 00:11:31 +00006574- Fixed a minor memory leak in dictobject.c. The content of the free
6575 list was not freed on interpreter shutdown.
6576
Georg Brandl21e99f42010-03-07 15:23:59 +00006577- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006578 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006579
Georg Brandl3ee81df2008-05-17 18:14:43 +00006580- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6581 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006582 to compact the internal free lists of pre-allocted ints and floats.
6583
Georg Brandl3ee81df2008-05-17 18:14:43 +00006584- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6585 calls. Python expected the return type int but the fork familie
6586 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006587
Georg Brandl3ee81df2008-05-17 18:14:43 +00006588- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6589 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006590
Georg Brandl3ee81df2008-05-17 18:14:43 +00006591- Issue #2025: Add tuple.count() and tuple.index() methods to comply
6592 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00006593
Georg Brandl3ee81df2008-05-17 18:14:43 +00006594- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
6595 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00006596
Georg Brandl3ee81df2008-05-17 18:14:43 +00006597- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6598 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006599
Georg Brandl3ee81df2008-05-17 18:14:43 +00006600- Patch #1473257: generator objects gain a gi_code attribute. This is
6601 the same object as the func_code attribute of the function that
6602 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006603
Georg Brandl3ee81df2008-05-17 18:14:43 +00006604- Issue #1920: "while 0" statements were completely removed by the
6605 compiler, even in the presence of an "else" clause, which is
6606 supposed to be run when the condition is false. Now the compiler
6607 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006608
Guido van Rossumeead05f2008-01-24 18:21:02 +00006609- A few crashers fixed: weakref_in_del.py (issue #1377858);
6610 loosing_dict_ref.py (issue #1303614, test67.py);
6611 borrowed_ref_[34].py (not in tracker).
6612
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006613- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006614 suppressed while an extension is loaded by calling SetErrorMode in
6615 dynload_win.c. The error is still reported properly.
6616
Georg Brandl3ee81df2008-05-17 18:14:43 +00006617- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006618 several extension methods and modules do not work without unicode
6619 support.
6620
Georg Brandl26543b12008-01-21 18:36:51 +00006621- Issue #1882: when compiling code from a string, encoding cookies in the
6622 second line of code were not always recognized correctly.
6623
Georg Brandl14404b62008-01-19 19:27:05 +00006624- Issue #1679: "0x" was taken as a valid integer literal.
6625
Georg Brandl6caad7d2008-01-26 14:19:22 +00006626- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006627 added.
6628
Christian Heimesc94e2b52008-01-14 04:13:37 +00006629- sys.float_info / PyFloat_GetInfo: The floating point information
6630 object was converted from a dict to a specialized structseq object.
6631
Georg Brandl3ee81df2008-05-17 18:14:43 +00006632- Patch #1816: Added sys.flags structseq. It exposes the status of
6633 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006634
Georg Brandl3ee81df2008-05-17 18:14:43 +00006635- Objects/structseq.c: Implemented new structseq representation. The
6636 patch makes structseqs (e.g. the return value of os.stat) more
6637 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006638
Georg Brandl3ee81df2008-05-17 18:14:43 +00006639- Patch #1700288: added a type attribute cache that caches method
6640 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006641
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006642- Bug #1776: __import__() no longer accepts filenames on any platform.
6643 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006644

6646
Georg Brandl3ee81df2008-05-17 18:14:43 +00006647- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6648 envvar and sys.dont_write_bytecode attribute. All these can be set
6649 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006650
Georg Brandl3ee81df2008-05-17 18:14:43 +00006651- Improve some exception messages when Windows fails to load an
6652 extension module. Now we get for example '%1 is not a valid Win32
6653 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006654
Georg Brandl3ee81df2008-05-17 18:14:43 +00006655- Bug #1481296: Fixed long(float('nan')) != 0L.

6658 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006659
Christian Heimes0a8143f2007-12-18 23:22:54 +00006660- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006661 and INF. float("nan"), float("inf") and float("-inf") now work on
6662 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006663
Georg Brandl3ee81df2008-05-17 18:14:43 +00006664- Compiler now generates simpler and faster code for dictionary
6665 literals. The oparg for BUILD_MAP now indicates an estimated
6666 dictionary size. There is a new opcode, STORE_MAP, for adding
6667 entries to the dictionary.

6699 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006700
Georg Brandl3ee81df2008-05-17 18:14:43 +00006701- Issue #1265: Fix a problem with sys.settrace, if the tracing
6702 function uses a generator expression when at the same time the
6703 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006704
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006705- sets and frozensets now have an isdisjoint() method.

6710
Georg Brandl21e99f42010-03-07 15:23:59 +00006711- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006712 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6713 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006714
Georg Brandl3ee81df2008-05-17 18:14:43 +00006715- Issue #1686386: Tuple's tp_repr did not take into account the
6716 possibility of having a self-referential tuple, which is possible
6717 from C code. Nor did object's tp_str consider that a type's tp_str
6718 could do something that could lead to an inifinite recursion.
6719 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6720 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006721
Georg Brandl3ee81df2008-05-17 18:14:43 +00006722- Issue #1164: It was possible to trigger deadlock when using the
6723 'print' statement to write to a file since the GIL was not released
6724 as needed. Now PyObject_Print() does the right thing along with
6725 various tp_print implementations of the built-in types and those in
6726 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006728- Issue #1147: Exceptions were directly allowing string exceptions in
6729 their throw() method even though string exceptions no longer
6730 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006732- Issue #1096: Prevent a segfault from getting the repr of a very
6733 deeply nested list by using the recursion counter.

Brett Cannon1e534b52007-09-07 04:18:30 +00006735- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006736 PyObject_Call() never calling back out to Python code to trigger
6737 recursion depth updates/checks. Required the creation of a static
6738 RuntimeError instance in case normalizing an exception put the
6739 recursion check value past its limit. Fixes crashers
6740 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00006755- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006756 __*__ attributes. (Some already existed, e.g., __doc__ and
6757 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006758
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006759- Add -3 option to the interpreter to warn about features that are
6760 deprecated and will be changed/removed in Python 3.0.
6761
Georg Brandl2134e752007-05-21 20:34:16 +00006762- Patch #1686487: you can now pass any mapping after '**' in function
6763 calls.
6764
Collin Winter62903052007-05-18 23:11:24 +00006765- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006766 "except E as target:". This is to provide forwards compatibility
6767 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006768
Brett Cannon229cee22007-05-05 01:34:02 +00006769- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006774- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006775 setting a plain string, ie don't expand to single letter identifiers.
6776
Raymond Hettinger13936692007-04-11 18:40:58 +00006777- Request #1191699: Slices can now be pickled.
6778
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006779- Request #1193128: str.translate() now allows a None argument for
6780 translations that only remove characters without re-mapping the
6781 remaining characters.
6782
Georg Brandl5cb76c12007-03-21 09:00:39 +00006783- Patch #1682205: a TypeError while unpacking an iterable is no longer

6785
Neal Norwitzaa754b72007-03-21 06:39:48 +00006786- Remove unused file Python/fmod.c.
6787
Guido van Rossum143b5642007-03-23 04:58:42 +00006788- Bug #1683368: The object.__init__() and object.__new__() methods are
6789 now stricter in rejecting excess arguments. The only time when
6790 either allows excess arguments is when it is not overridden and the
6791 other one is. For backwards compatibility, when both are
6792 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006793 warning later). Also, type.__init__() insists on the same signature
6794 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006795
Georg Brandl3ee81df2008-05-17 18:14:43 +00006796- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6797 object to complex using its __complex__() method before falling back
6798 to the __float__() method. Therefore, the functions in the cmath
6799 module now can operate on objects that define a __complex__()
6800 method.

6817
Georg Brandl7b9c5552007-03-12 14:30:05 +00006818- Bug #1678647: write a newline after printing an exception in any
6819 case, even when converting the value to a string failed.
6820
Georg Brandl871f1bc2007-03-12 13:17:36 +00006821- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006822 its argument, if it exists. If not, it will work like before. This
6823 allows customizing the output of dir() in the presence of a
6824 __getattr__().

6833 parthensized forms. This means complex(repr(x)) now works instead of
6834 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006835
Georg Brandlaa2321b2007-03-07 00:40:28 +00006836- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006837 makes the filenames the warning module prints much more sensible
6838 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006839

Georg Brandl0fca97a2007-03-05 22:28:08 +00006851- Patch #1674228: when assigning a slice (old-style), check for the
6852 sq_ass_slice instead of the sq_slice slot.
6853
Georg Brandl3ee81df2008-05-17 18:14:43 +00006854- When printing an unraisable error, don't print exceptions. before

7465 Python would crash instead of raising an error.
7466

7479
Georg Brandl3ee81df2008-05-17 18:14:43 +00007480- unittest now verifies more of its assumptions. In particular,

7482 accepted in TestSuite.addTest(). This should cause no
7483 incompatibility since it never made sense with ordinary subclasses
7484 -- the failure just occurred later, with a more cumbersome
7485 exception.

7768 obtained from the TLS negotiation itself. Patch contributed by Bill
7769 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007770
Georg Brandl3ee81df2008-05-17 18:14:43 +00007771- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007772 that the SMTP.starttls() caller no longer needs to call ehlo()
7773 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007774 does not claim to support starttls. Adds the
7775 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

7856 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7857 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00007874 time so that opening a database previously created with the DB_DUP
7875 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7876 opens. Specifically: dictionary assignment to a DB object will
7877 replace all values for a given key when the database allows
7878 duplicate values. DB users should use DB.put(k, v) when they want
7879 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007880

7886 characters with ASCII value less than 32. Also, it correctly quotes
7887 dots only if they occur on a single line, as opposed to the previous
7888 behavior of quoting dots if they are the second character of any
7889 line.

8212-----
8213
Georg Brandl3ee81df2008-05-17 18:14:43 +00008214- Unified naming convention for free lists and their limits. All free
8215 lists in Object/ are named ``free_list``, the counter ``numfree``
8216 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
8217 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00008218
Georg Brandl3ee81df2008-05-17 18:14:43 +00008219- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8220 to ``PyTuple_SetItem``, it can be used to populate a brand new
8221 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00008222
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008223- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008225- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
8226 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
8227 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008228
8229- Patch #1720595: add T_BOOL to the range of structmember types.
8230
8231- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
8232 ``PyFloat_GetInfo()`` to the float API.
8233
Georg Brandl3ee81df2008-05-17 18:14:43 +00008234- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8235 of w# format code incorrectly truncated the length to an int, even
8236 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8237 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008238
Georg Brandl3ee81df2008-05-17 18:14:43 +00008239- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
8240 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008241
Georg Brandl3ee81df2008-05-17 18:14:43 +00008242- PEP 3123: Provide forward compatibility with Python 3.0, while
8243 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
8244 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008245
Georg Brandl3ee81df2008-05-17 18:14:43 +00008246- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
8247 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008248
8249- Patch #1733960: Allow T_LONGLONG to accept ints.
8250
8251- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
8252
Christian Heimes000a0742008-01-03 22:16:32 +00008253- Added a new API function ``PyImport_ImportModuleNoBlock``.

8256
8257- Fix some leftovers from the conversion from int to Py_ssize_t
8258 (relevant to strings and sequences of more than 2**31 items).
8259
8260- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8261 outside of pystate.c and should not be necessary.
8262
Georg Brandl3ee81df2008-05-17 18:14:43 +00008263- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8264 absolute imports. In earlier versions they might have used relative
8265 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008266
Georg Brandl3ee81df2008-05-17 18:14:43 +00008267- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8268 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008269
Georg Brandl3ee81df2008-05-17 18:14:43 +00008270- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
8271 macro so it can be used as an expression.

8276
Georg Brandl3ee81df2008-05-17 18:14:43 +00008277- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
8278 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
8279 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
8280 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00008281
Georg Brandl3ee81df2008-05-17 18:14:43 +00008282- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00008295- Removed the macfs module. It had been deprecated since Python 2.5.
8296 This lead to the deprecation of macostools.touched() as it relied
8297 solely on macfs and was a no-op under OS X.
