625
626- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
627 and later systems as is currently done for Python 3.x installers.
628 For 2.7.7 only, we will provide three installers:
629 the legacy deprecated 10.3+ 32-bit-only format;
630 the newer 10.5+ 32-bit-only format;
631 and the unchanged 10.6+ 64-/32-bit format.
632 Although binary installers will no longer be available from
633 python.org as of 2.7.8, it will still be possible to build from
634 source on 10.3.9 and 10.4 systems if necessary.
635 See Mac/BuildScript/README.txt for more information.

2014 32-bit-only installer Pythons on systems with Xcode 4 (currently
2015 OS X 10.8, 10.7, and optionally 10.6).
2016 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2017 * Since Xcode 4 removes ppc support, extension module builds now
2018 check for ppc compiler support and by default remove ppc and
2019 ppc64 archs when they are not available.
2020 * Extension module builds now revert to using system installed
2021 headers and libs (/usr and /System/Library) if the SDK used
2022 to build the interpreter is not installed or has moved.
2023 * Try to avoid building extension modules with deprecated
2024 and problematic Apple llvm-gcc compiler. If original compiler
2025 is not available, use clang instead by default.

2375
Mark Dickinsondbbed042011-09-19 16:38:08 +01002376- Issue #12973: Fix overflow checks that invoked undefined behaviour in
2377 int.__pow__. These overflow checks were causing int.__pow__ to produce
2378 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01002379 compiler optimizing the check away. Also fix similar overflow checks
2380 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
2381 bugs caused test failures with recent versions of Clang.

2393 cleared by the garbage collector. This fixes a segfault when an instance
2394 and its type get caught in a reference cycle, and the instance's
2395 deallocator calls one of the methods on the type (e.g. when subclassing

Florent Xiclunac2279652012-02-12 14:49:03 +01002449- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002450 has left two versions of customize_compiler, the original in
2451 distutils.sysconfig and another copy in distutils.ccompiler, with some
2452 parts of distutils calling one and others using the other.

2454 is the case in 3.x.
2455
Ned Deily0d0ea482012-02-10 12:59:06 +01002456- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2457 Distutils-based packages with C extension modules may fail because
2458 Apple has removed gcc-4.2, the version used to build python.org
2459 64-bit/32-bit Pythons. If the user does not explicitly override
2460 the default C compiler by setting the CC environment variable,
2461 Distutils will now attempt to compile extension modules with clang
2462 if gcc-4.2 is required but not found. Also as a convenience, if
2463 the user does explicitly set CC, substitute its value as the default
2464 compiler in the Distutils LDSHARED configuration variable for OS X.
2465 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2466 SDK, neither of which are available in Xcode 4. This change does not
2467 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002717- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2718 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2719 interpreter process. This could cause failures in non-Distutils subprocesses
2720 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002721 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002722 deployment target only in the environment of each build subprocess. It is
2723 still possible to globally override the default by setting
2724 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2725 greater or equal to the default value, the value with which the interpreter
2726 was built.

2755 updating the check interval, so if the user decreases the check interval,
2756 the ticker doesn't have to wind down to zero from the old starting point
2757 before the new interval takes effect. And if the user increases the
2758 interval, it makes sure the new limit takes effect right away rather have an
2759 early task switch before recognizing the new interval.

3740 This prevents user-created self-referencing ordered dictionaries from
3741 becoming permanently uncollectable GC garbage. The downside is that
3742 removing __del__ means that the internal doubly-linked list has to wait for
3743 GC collection rather than freeing memory immediately when the refcnt drops
3744 to zero.

3752 to fetch the original errno, or to filter timeout errors. Now the
3753 original error is re-raised.

3773 falling into recursion.
3774
R. David Murray7c4bf552010-08-25 01:45:57 +00003775- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004202- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4203 start byte and the continuation byte(s) are now considered invalid, instead
4204 of the number of bytes specified by the start byte.
4205 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4206 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4207 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004216- Issue #8748: Fix two issues with comparisons between complex and integer
4217 objects. (1) The comparison could incorrectly return True in some cases
4218 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4219 (2) The comparison raised an OverflowError for large integers, leading
4220 to unpredictable exceptions when combining integers and complex objects
4221 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00004223- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00004360- Issue #1533: Fix inconsistency in range function argument processing: any
4361 non-float non-integer argument is now converted to an integer (if possible)
4362 using its __int__ method. Previously, only small arguments were treated this
4363 way; larger arguments (those whose __int__ was outside the range of a C long)
4364 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00004372 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +00004373 benefit compared to the dynamic memory allocation fallback. Patch by

4399 messages when accessing undefined class attributes because of the cheap
4400 inheritance with the underlying socket object. The cheap inheritance has been
4401 deprecated.
Giampaolo Rodolàf7454fa2010-05-06 17:57:06 +00004402

Georg Brandlfee0f442010-05-22 21:26:21 +00004414- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4415 operation raises multiple signals and more than one of those signals is
4416 trapped, the specification determines the order in which the signals should be
4417 handled. In many cases this order wasn't being followed, leading to the wrong
4418 Python exception being raised.
Mark Dickinson4f96f5f2010-05-04 14:25:50 +00004419

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004588- Issue #7301: Add environment variable $PYTHONWARNINGS.
4589
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004590- Issue #8329: Don't return the same lists from select.select when no fds are
4591 changed.
4592
Georg Brandlfee0f442010-05-22 21:26:21 +00004593- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004594 on 64-bit machines. The shift count for either left or right shift is
4595 permitted to be up to sys.maxsize.
4596
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004597- Ensure that tokenization of identifiers is not affected by locale.
4598
Georg Brandlfee0f442010-05-22 21:26:21 +00004599- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00004601- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
4602
Georg Brandlfee0f442010-05-22 21:26:21 +00004603- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4604 with a non-empty format string. This is an effort to future-proof user
4605 code. If a derived class does not currently implement __format__ but later
4606 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004607 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004608 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004609
Antoine Pitroua57df2c2010-03-31 21:32:15 +00004610- Issue #8268: Old-style classes (not just instances) now support weak
4611 references.
4612

4622
Victor Stinner66644262010-03-10 22:30:19 +00004623- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00004624 (SIGINT). If an error occurs while importing the site module, the error is
4625 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00004626 module.

4640
Georg Brandlfee0f442010-05-22 21:26:21 +00004641- Issue #8257: The Decimal construct now accepts a float instance directly,
4642 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004643
4644 >>> Decimal(1.1)
4645 Decimal('1.100000000000000088817841970012523233890533447265625')
4646
Raymond Hettinger34c35b22010-04-03 10:22:00 +00004647- collections.Counter() now supports a subtract() method.
4648
Georg Brandlfee0f442010-05-22 21:26:21 +00004649- The functools module now has a total_ordering() class decorator to simplify
4650 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00004651
Georg Brandlfee0f442010-05-22 21:26:21 +00004652- The functools module also adds cmp_to_key() as a tool to transition old-style
4653 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00004654
Georg Brandlfee0f442010-05-22 21:26:21 +00004655- Issue #8294: The Fraction constructor now accepts Decimal and float instances
4656 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00004657
Georg Brandlfee0f442010-05-22 21:26:21 +00004658- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4659 InvalidOperation instead of returning False. (Comparisons involving a quiet
4660 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4661 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004662
Georg Brandlfee0f442010-05-22 21:26:21 +00004663- Issue #2531: Comparison operations between floats and Decimal instances now
4664 return a result based on the numeric values of the operands; previously they
4665 returned an arbitrary result based on the relative ordering of id(float) and
4666 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004667
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004668- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004669 argument `-` which tells it to read files to compile from stdin. Each line is
4670 read on demand and the named file is compiled immediately. (Original patch by
4671 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004672
Georg Brandlfee0f442010-05-22 21:26:21 +00004673- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
4674 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00004676- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4677 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004678 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00004679
Georg Brandlfee0f442010-05-22 21:26:21 +00004680- Comparisons using one of <, <=, >, >= between a complex instance and a
4681 Fractions instance now raise TypeError instead of returning True/False. This
4682 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4683 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00004684

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004694- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00004695 didn't support chflags() (for example ZFS under FreeBSD). The error is now
4696 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004697
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00004698- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
4699 deprecated.
4700

Georg Brandlfee0f442010-05-22 21:26:21 +00004739 for ``TimedRotatingFileHandler`` by using the modification time of an existing
4740 log file to compute the next rollover time. If the log file does not exist,
4741 the current time is used as the basis for the computation.

Georg Brandlba83f822010-03-14 09:50:54 +00004751- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
4752 a base64 transfer-encoded payload *after* decoding it; it no longer does.
4753 This is a behavior change, so email's minor version number is now bumped, to
4754 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00004782- Issue #8300: When passing a non-integer argument to struct.pack with any
4783 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00004787- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4788 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4789 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004790 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4791 inconsistent: __int__ was used for some integer codes but not for others, and
4792 the set of integer codes for which it was used differed between native packing
4793 and standard packing.)

5198-----------------
5199
Georg Brandlba83f822010-03-14 09:50:54 +00005200- The ``__complex__()`` method is now looked up on the class of instances to
5201 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00005203- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,

5205
Mark Dickinson1b34d252010-01-01 17:27:30 +00005206- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005207 DeprecationWarning when passed a float argument where an integer was expected.
5208 These functions and methods now raise TypeError instead. The majority of the
5209 effects of this change are in the extension modules, but some core functions
5210 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5211 and many unicode/str methods.

5222 used to drop the time part of the result.
5223
Georg Brandlba83f822010-03-14 09:50:54 +00005224- Issue #1811: Improve accuracy and cross-platform consistency for true division
5225 of integers: the result of a/b is now correctly rounded for ints a and b (at
5226 least on IEEE 754 platforms), and in particular does not depend on the
5227 internal representation of a long.

5235
Georg Brandlba83f822010-03-14 09:50:54 +00005236 These executables now work properly with the arch(1) command: ``arch -ppc
5237 python`` will start a universal binary version of python in PPC mode (unlike

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005378

Georg Brandlba83f822010-03-14 09:50:54 +00005393- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5394 decimal string that's guaranteed to round back to x under correct rounding
5395 (with round-half-to-even rounding mode). Previously it gave a string based on
5396 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5397 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5398 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005399
Georg Brandlba83f822010-03-14 09:50:54 +00005400- Issue #7117: On almost all platforms: float-to-string and string-to-float
5401 conversions within Python are now correctly rounded. Places these conversions
5402 occur include: str for floats and complex numbers; the float and complex
5403 constructors; old-style and new-style numeric formatting; serialization and
5404 deserialization of floats and complex numbers using marshal, pickle and json;
5405 parsing of float and imaginary literals in Python code; Decimal-to-float
5406 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005407
Georg Brandlba83f822010-03-14 09:50:54 +00005408 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5409 providing correctly-rounded strtod and dtoa C functions. This code is
5410 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5411 the C compiler. There may be a small number of platforms on which correct
5412 operation of this code cannot be guaranteed, so the code is not used: notably,
5413 this applies to platforms where the C double format is not IEEE 754 binary64,
5414 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5415 and Python's configure script is unable to determine how to change the FPU
5416 precision. On these platforms conversions use the platform strtod and dtoa,
5417 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005419- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5420 uses the correctly-rounded string <-> float conversions described above (when
5421 available), and so produces correctly rounded results that will display nicely
5422 under the float repr. There are two related small changes: (1) round now
5423 accepts any class with an ``__index__()`` method for its second argument (but
5424 no longer accepts floats for the second argument), and (2) an excessively
5425 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5426 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00005568
Georg Brandlba83f822010-03-14 09:50:54 +00005569 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
5570 (2) parsing of strings representing infinities and nans was locale aware; and
5571 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00005573- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5574 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5575 but with at least one decimal point and with a default precision
5576 of 12. Previously, the behavior the same but with a default precision of 6.
5577 This more closely matches ``str()``, and reduces surprises when adding
5578 alignment flags to the empty presentation type. This also affects the new
5579 complex.__format__ in the same way.
5580
5581- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
5582 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00005644 untrackable objects are not tracked by the garbage collector. This can reduce

5653 internal representation of integers, for performance reasons. Base 2**30 is
5654 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandlba83f822010-03-14 09:50:54 +00005762- Issue #4445: Replace ``sizeof(PyStringObject)`` with
5763 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
5764 instances. On a typical machine this saves 3 bytes of memory (on average) per
5765 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00005767- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

5769 instead of throwing a MemoryError.
5770
Georg Brandlba83f822010-03-14 09:50:54 +00005771- Issue #3689: The list reversed iterator now supports __length_hint__ instead

Benjamin Petersonc078f922008-11-21 22:27:24 +00005774- Issue #4367: Python would segfault during compiling when the unicodedata

5776
Georg Brandlba83f822010-03-14 09:50:54 +00005777- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5778 file objects with closefd=False. The file descriptor is still kept open but
5779 the file object behaves like a closed file. The ``FileIO`` object also got a
5780 new readonly attribute ``closefd``.

Benjamin Peterson46cc6d12008-11-19 21:49:09 +00005782- Issue #4348: Some bytearray methods returned that didn't cause any change to

5799
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005800- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00005803- On windows, ``os.chdir()`` given unicode was not working if
5804 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5805 this code path is really executed because I cannot move to such directory on
5806 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00005807
Georg Brandlba83f822010-03-14 09:50:54 +00005808- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5809 element is temporarily replaced with an equivalent frozenset. But the
5810 eventual KeyError would always report the empty ``frozenset()`` as the missing
5811 key. Now it correctly refers to the initial element.

5829 returned them on 64bit platforms.
5830
Walter Dörwalded960ac2009-05-03 22:36:33 +00005831- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5832 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5833 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5834 of using the replace error handler in PyUnicode_DecodeUTF8().
5835
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005836- Issue #3739: The unicode-internal encoder now reports the number of characters
5837 consumed like any other encoder (instead of the number of bytes).
5838
Georg Brandlba83f822010-03-14 09:50:54 +00005839- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
5840 allocator will be automatically disabled when running under Valgrind. This
5841 gives improved memory leak detection when running under Valgrind, while taking
5842 advantage of pymalloc at other times.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00007210- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
7211
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007212- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7213 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7214 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7215 ``printf`` function, whereas PyString_FromFormat has an independent
7216 implementation and uses "%zd" on all platforms for size_t values.
7217 This makes a difference on win64, where ``printf`` needs "%Id" to display
7218 64bit values.
7219
Benjamin Peterson97179b02008-09-09 20:55:01 +00007220- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

7224 object; previously an int would be returned for small values. the __long__
7225 method is allowed to return either an int or a long, but the behaviour of
7226 float objects should not change to respect backward compatibility.
7227
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00007228- Issue #3751: str.rpartition would perform a left-partition when called with
7229 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00007234 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007235 was correctly parsed but parsing of subsequent arguments failed.
7236
Vinay Sajip35e3b032008-09-01 14:33:59 +00007237- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007238 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7239 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7240 when given a tuple of classes as second argument, were looking up
7241 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7242 type object.
7243
Neal Norwitz18aa3882008-08-24 05:04:52 +00007244- Fix crashes on memory allocation failure found with failmalloc.
7245
7246- Fix memory leaks found with valgrind and update suppressions file.

Brett Cannon1eaf0742008-09-02 01:25:16 +00007313 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7314 for catch_warnings() also led to an improvement in the raising of a

7387-----------------
7388
Guido van Rossumf8402962008-08-20 15:01:50 +00007389- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7390 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7391 extensions do not automatically benefit from the class attribute
7392 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7393 to their tp_flags field if they care. This is a backwards
7394 compatibility feature; in 3.0, all types will use the cache by
7395 default.
7396
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007397- Keyword arguments can now follow starred arguments. (``f(a, *args,
7398 keyword=23)`` is now valid syntax.)
7399
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007400- ctypes function pointers that are COM methods have a boolean True
7401 value again.
7402
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007403- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7404 by denying s# to parse objects that have a releasebuffer procedure,

Mark Dickinsonb6467572008-08-04 21:30:09 +00007410- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7411 ValueError consistently across platforms.
7412
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007413- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7414 (64bit Unix, for example), unichr() would truncate its argument and return
7415 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7416
Neal Norwitze7d8be82008-07-31 17:17:14 +00007417- Apply security patches from Apple.

Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007419- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7420 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7421
Antoine Pitrou92f82162008-07-25 22:22:08 +00007422- Issue #1819: function calls with several named parameters are now on
7423 average 35% faster (as measured by pybench).
7424
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007425- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7426 the python debugger steps into a class statement: the free variables (local
7427 variables defined in an outer scope) would be deleted from the outer scope.
7428
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007429- Issue #2620: Overflow checking when allocating or reallocating memory
7430 was not always being done properly in some python types and extension
7431 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7432 all been updated to perform better checks and places in the code that
7433 would previously leak memory on the error path when such an allocation
7434 failed have been fixed.

7440
Benjamin Petersone977ad42008-08-20 01:42:01 +00007441- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7442 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7443
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007444- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7445 version reported by these tools does not necessarily follow the python
7446 version numbering scheme, so the module is less strict when parsing it.
7447
Nick Coghlanf70385a2008-08-18 12:42:46 +00007448- Issue #2235: Added Py3k warnings for types which will become unhashable
7449 under the stricter __hash__ inheritance rules in 3.0. Several types
7450 which did not meet the rules for hash invariants and were already
7451 unhashable in 3.0 have now been explicitly flagged as unhashable in
7452 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7453 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7454
Brett Cannon88f801d2008-08-18 00:46:22 +00007455- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7456 imported into the module but exposed as part of the module's API.
7457

7477 after a 302 response in the case of not going through a proxy.
7478
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007479- Issue #2676: in the email package, content-type parsing was hanging on
7480 pathological input because of quadratic or exponential behaviour of a
7481 regular expression.
7482
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007483- Issue #3476: binary buffered reading through the new "io" library is now
7484 thread-safe.
7485
Brett Cannonbf3157b2008-08-14 05:00:03 +00007486- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7487 since mimetools itself is deprecated. Because modules are cached, all
7488 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7489
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007490- Issue #3134: shutil referenced undefined WindowsError symbol.

7493 menu entries were not deleted.
7494
Brett Cannon83e81842008-08-09 23:30:55 +00007495- Copied the implementation of reduce() to _functools.reduce() to have a

7497
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007498- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7499 a MemoryError rather than silently stop the iteration.
7500
Guido van Rossum59ce9012008-08-09 14:55:34 +00007501- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7502 to _sre.compile() will now be rejected. This should not affect anybody
7503 since the re.compile() function never generates invalid re-bytecode.
7504
Skip Montanaroa032bf42008-08-08 22:52:51 +00007505- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7506 upon first access it can be automatically initialized from the csv file if
7507 it wasn't initialized during instantiation.
7508
Brett Cannon3aa2a492008-08-06 22:28:09 +00007509- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7510 the reload() built-in has been removed.
7511
Brett Cannon7e30b672008-08-04 21:52:25 +00007512- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007513 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

7521 raised an AttributeError.
7522
Benjamin Peterson01a24322008-07-28 23:35:27 +00007523- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00007524 asking for a specific length. This problem only affected files opened
7525 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007526

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00007550- Issue #3394: zipfile.writestr sets external attributes when passed a
7551 file name rather than a ZipInfo instance, so files are extracted with
7552 mode 0600 rather than 000 under Unix.
7553
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007554- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7555 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00007566- Issue #2235: the C API function PyObject_HashNotImplemented and its
7567 interaction with the tp_hash slot (added in 2.6b2) are now documented
7568
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007569- Issue #643841: The language reference now provides more detailed
7570 coverage of the lookup process for special methods. The disclaimers
7571 regarding lack of coverage of new-style classes have also been
7572 removed, since the coverage is now fairly reasonable.

7576================================
7577
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007578*Release date: 17-Jul-2008*
7579
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007580Core and Builtins
7581-----------------
7582
Georg Brandl3e483f62008-07-16 22:57:41 +00007583- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7584 its methods now allow for items objects that can be converted to
7585 an integer using operator.index().
7586
Mark Dickinson64b7e502008-07-16 09:40:03 +00007587- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7588 produced a ValueError instead of giving the correct float.
7589
Eric Smitha5fa5a22008-07-16 00:11:49 +00007590- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7591 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7592
Mark Dickinson7103aa42008-07-15 19:08:33 +00007593- Issue #3008: the float type has a new instance method 'float.hex'
7594 and a new class method 'float.fromhex' to convert floating-point
7595 numbers to and from hexadecimal strings, respectively.
7596
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007597- Issue #2235: __hash__ is once again inherited by default. To allow
7598 collections.Hashable to remain meaningful in the presence of the
7599 default hash implementation (object.__hash__), it is now possible
7600 to explicit block inheritance of hash by setting __hash__=None at
7601 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7602 level.
7603
Nick Coghlanb028f502008-07-13 14:52:36 +00007604- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7605 the parent module cannot be found while performing an absolute import.
7606 This means that an incorrectly defined __package__ attribute will
7607 now only prevent relative imports in that module rather than causing
7608 all imports from that module to fail.
7609
Nick Coghlan14ff9942008-07-08 14:21:42 +00007610- Issue #2517: Allow unicode messages in Exceptions again by correctly
7611 bypassing the instance dictionary when looking up __unicode__ on
7612 new-style classes.
7613
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007614- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7615 set to a custom object whose write() method happens to install
7616 another file in sys.stdout.
7617
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007618- Issue #3088: Corrected a race condition in classes derived from
7619 threading.local: the first member set by a thread could be saved in
7620 another thread's dictionary.
7621
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007622- Issue #3004: Minor change to slice.indices(): the start and stop
7623 arguments are now treated identically, making the behaviour easier
7624 to describe and understand. For example, slice(None, -10,
7625 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7626 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7627 10, -1).
7628
Georg Brandl278fc502008-07-19 12:46:12 +00007629- Issue #3219: Calling a function with repeated keyword arguments,
7630 f(a=2, a=23), would not cause a syntax error. This was a regression
7631 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007632
Georg Brandl278fc502008-07-19 12:46:12 +00007633- Issue #2862: Make int and float freelist management consistent with
7634 other freelists. Changes their CompactFreeList apis into
7635 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00007636

7638-------
7639
Thomas Heller57adf222008-08-14 19:10:48 +00007640- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
7641 api functions without holding the GIL, which could lead to a fatal
7642 error when they failed.
7643
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007644- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00007652- Issue #3125: Remove copy_reg in multiprocessing and replace it with
7653 ForkingPickler.register() to resolve conflict with ctypes.
7654
Vinay Sajip51e65192008-07-18 09:01:10 +00007655- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00007656
Thomas Heller880f5292008-07-15 19:39:38 +00007657- Issue #3313: Fixed a crash when a failed dlopen() call does not set
7658 a valid dlerror() message.
7659
Thomas Heller2bad6572008-07-15 17:19:50 +00007660- Issue #3258: Fixed a crash when a ctypes POINTER type to an
7661 incomplete structure was created.
7662
Brett Cannon3d0b9f02008-07-13 01:15:07 +00007663- Issue #3339: dummy_thread.acquire() should not return None.

7666
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007667- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00007668
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007669- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7670 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007671 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007672 content-length. The problem had been corrected in the 2.4 branch, but never
7673 merged into trunk.
7674
Georg Brandle78fbcc2008-07-05 10:13:36 +00007675- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007686 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00007687
Nick Coghlanc060b0e2008-07-02 13:09:19 +00007688- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
7689 handling is now the same as that of other special attributes like __name__).
7690
Brett Cannon8bb8fa52008-07-02 01:57:08 +00007691- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
7692 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00008079 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008080
8081 This is controlled by the configure argument ``--with-universal-archs``:
8082
8083 - ``--with-universal-archs=all``: install 4-way universal
8084
8085 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8086
8087 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8088
8089 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008140- Issue #1631171: Re-implement the 'warnings' module in C (the
8141 original Python code has been kept as backup). This will allow for
8142 using the 'warning's machinery in such places as the parser where
8143 use of pure Python code is not possible. Both the ``showarning()``
8144 and ``formatwarning()`` gain an optional 'line' argument which is
8145 not called by default for backwards-compatibility reasons. Setting
8146 ``warnings.showwarning()`` to an implementation that lacks support
8147 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008210- Issue #2550: The approach used by client/server code for obtaining
8211 ports to listen on in network-oriented tests has been refined in an
8212 effort to facilitate running multiple instances of the entire
8213 regression test suite in parallel without issue.
8214 test_support.bind_port() has been fixed such that it will always
8215 return a unique port -- which wasn't always the case with the
8216 previous implementation, especially if socket options had been set
8217 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8218 new implementation of bind_port() will actually raise an exception
8219 if it is passed an AF_INET/SOCK_STREAM socket with either the
8220 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8221 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8222 the socket it's been passed. This currently only applies to
8223 Windows. This option prevents any other sockets from binding to the
8224 host/port we've bound to, thus removing the possibility of the
8225 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8226 when a second SOCK_STREAM socket binds and accepts to a host/port
8227 that's already been bound by another socket. The optional preferred
8228 port parameter to bind_port() has been removed. Under no
8229 circumstances should tests be hard coding ports!
8230
8231 test_support.find_unused_port() has also been introduced, which will
8232 pass a temporary socket object to bind_port() in order to obtain an
8233 unused port. The temporary socket object is then closed and
8234 deleted, and the port is returned. This method should only be used
8235 for obtaining an unused port in order to pass to an external program
8236 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8237 a parameter to a server-oriented class that doesn't give you direct
8238 access to the underlying socket used.
8239
8240 Finally, test_support.HOST has been introduced, which should be used
8241 for the host argument of any relevant socket calls (i.e. bind and
8242 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008243
8244 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008245 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

8247 test_asynchat and test_socket_ssl.
8248
Georg Brandl3ee81df2008-05-17 18:14:43 +00008249 It is now possible for multiple instances of the regression test
8250 suite to run in parallel without issue.

8517-----------------
8518
Fred Drakea8ee94b2008-03-01 02:45:07 +00008519- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00008520 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00008521
Georg Brandlad61bc82008-02-23 15:11:18 +00008522- Issue #2067: file.__exit__() now calls subclasses' close() method.
8523
8524- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00008525
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008526- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00008527 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00008528
Eric Smitha73fbe72008-02-23 03:09:44 +00008529- Added the future_builtins module, which contains hex() and oct().
8530 These are the PEP 3127 version of these functions, designed to be
8531 compatible with the hex() and oct() builtins from Python 3.0. They
8532 differ slightly in their output formats from the existing, unchanged
8533 Python 2.6 builtins. The expected usage of the future_builtins
8534 module is:
8535 from future_builtins import hex, oct
8536
Eric Smith7ef40bf2008-02-20 23:34:22 +00008537- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8538 exponents for exponents with absolute value < 100. Follows C99
8539 standard. This is a change on Windows, which would use 3 digits.
8540 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8541 so that any alterations it does to the resulting string will be
8542 available in stringlib/formatter.h (for float.__format__).
8543
Eric Smith5a3c1352008-02-19 13:21:56 +00008544- Implemented PEP 3101, Advanced String Formatting. This adds a new
8545 builtin format(); a format() method for str and unicode; a
8546 __format__() method to object, str, unicode, int, long, float, and
8547 datetime; the class string.Formatter; and the C API
8548 PyObject_Format().
8549
Georg Brandl3ee81df2008-05-17 18:14:43 +00008550- Fixed several potential crashes, all caused by specially crafted
8551 __del__ methods exploiting objects in temporarily inconsistent
8552 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008553
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008554- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008555 prevent a possible crash: an Abstract Base Class would try to access
8556 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008557
Georg Brandl3ee81df2008-05-17 18:14:43 +00008558- Fixed repr() and str() of complex numbers with infinity or nan as
8559 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00008560
Georg Brandl3ee81df2008-05-17 18:14:43 +00008561- Clear all free lists during a gc.collect() of the highest generation
8562 in order to allow pymalloc to free more arenas. Python may give back
8563 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008564
Georg Brandl3ee81df2008-05-17 18:14:43 +00008565- Issue #2045: Fix an infinite recursion triggered when printing a
8566 subclass of collections.defaultdict, if its default_factory is set
8567 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008568
Christian Heimesf75dbef2008-02-08 00:11:31 +00008569- Fixed a minor memory leak in dictobject.c. The content of the free
8570 list was not freed on interpreter shutdown.
8571
Georg Brandl21e99f42010-03-07 15:23:59 +00008572- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008573 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008574
Georg Brandl3ee81df2008-05-17 18:14:43 +00008575- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8576 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008577 to compact the internal free lists of pre-allocted ints and floats.
8578
Georg Brandl3ee81df2008-05-17 18:14:43 +00008579- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8580 calls. Python expected the return type int but the fork familie
8581 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008582
Georg Brandl3ee81df2008-05-17 18:14:43 +00008583- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8584 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008585
Georg Brandl3ee81df2008-05-17 18:14:43 +00008586- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8587 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00008588
Georg Brandl3ee81df2008-05-17 18:14:43 +00008589- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8590 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00008591
Georg Brandl3ee81df2008-05-17 18:14:43 +00008592- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8593 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008594
Georg Brandl3ee81df2008-05-17 18:14:43 +00008595- Patch #1473257: generator objects gain a gi_code attribute. This is
8596 the same object as the func_code attribute of the function that
8597 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008598
Georg Brandl3ee81df2008-05-17 18:14:43 +00008599- Issue #1920: "while 0" statements were completely removed by the
8600 compiler, even in the presence of an "else" clause, which is
8601 supposed to be run when the condition is false. Now the compiler
8602 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008603
Guido van Rossumeead05f2008-01-24 18:21:02 +00008604- A few crashers fixed: weakref_in_del.py (issue #1377858);
8605 loosing_dict_ref.py (issue #1303614, test67.py);
8606 borrowed_ref_[34].py (not in tracker).
8607
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008608- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008609 suppressed while an extension is loaded by calling SetErrorMode in
8610 dynload_win.c. The error is still reported properly.
8611
Georg Brandl3ee81df2008-05-17 18:14:43 +00008612- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008613 several extension methods and modules do not work without unicode
8614 support.
8615
Georg Brandl26543b12008-01-21 18:36:51 +00008616- Issue #1882: when compiling code from a string, encoding cookies in the
8617 second line of code were not always recognized correctly.
8618
Georg Brandl14404b62008-01-19 19:27:05 +00008619- Issue #1679: "0x" was taken as a valid integer literal.
8620
Georg Brandl6caad7d2008-01-26 14:19:22 +00008621- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008622 added.
8623
Christian Heimesc94e2b52008-01-14 04:13:37 +00008624- sys.float_info / PyFloat_GetInfo: The floating point information
8625 object was converted from a dict to a specialized structseq object.
8626
Georg Brandl3ee81df2008-05-17 18:14:43 +00008627- Patch #1816: Added sys.flags structseq. It exposes the status of
8628 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008629
Georg Brandl3ee81df2008-05-17 18:14:43 +00008630- Objects/structseq.c: Implemented new structseq representation. The
8631 patch makes structseqs (e.g. the return value of os.stat) more
8632 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008633
Georg Brandl3ee81df2008-05-17 18:14:43 +00008634- Patch #1700288: added a type attribute cache that caches method
8635 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008636
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008637- Bug #1776: __import__() no longer accepts filenames on any platform.
8638 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008639
Georg Brandlaed6c662008-01-07 17:25:53 +00008640- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8641
Georg Brandl3ee81df2008-05-17 18:14:43 +00008642- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8643 envvar and sys.dont_write_bytecode attribute. All these can be set
8644 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008645
Georg Brandl3ee81df2008-05-17 18:14:43 +00008646- Improve some exception messages when Windows fails to load an
8647 extension module. Now we get for example '%1 is not a valid Win32
8648 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008649
Georg Brandl3ee81df2008-05-17 18:14:43 +00008650- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008652- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
8653 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008654
Christian Heimes0a8143f2007-12-18 23:22:54 +00008655- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008656 and INF. float("nan"), float("inf") and float("-inf") now work on
8657 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008658
Georg Brandl3ee81df2008-05-17 18:14:43 +00008659- Compiler now generates simpler and faster code for dictionary
8660 literals. The oparg for BUILD_MAP now indicates an estimated
8661 dictionary size. There is a new opcode, STORE_MAP, for adding
8662 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00008663
Georg Brandl3ee81df2008-05-17 18:14:43 +00008664- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00008665
Georg Brandl3ee81df2008-05-17 18:14:43 +00008666- Issue #1620: New property decorator syntax was modifying the
8667 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00008668
Georg Brandl3ee81df2008-05-17 18:14:43 +00008669- Issue #1538: Avoid copying string in split/rsplit if the split char
8670 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00008671
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00008672- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00008673 SystemError.
8674
Nick Coghlanef01d822007-12-03 12:55:17 +00008675- PEP 366: Allow explicit relative imports when executing modules

8677 __package__ attribute.
8678
Georg Brandl3ee81df2008-05-17 18:14:43 +00008679- Issue #1402: Fix a crash on exit, when another thread is still
8680 running, and if the deallocation of its frames somehow calls the
8681 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00008682

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00008686 attribute of an empty cell object.
8687
Georg Brandl3ee81df2008-05-17 18:14:43 +00008688- Issue #1460: The utf-7 incremental decoder did not accept truncated
8689 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00008690
Georg Brandl3ee81df2008-05-17 18:14:43 +00008691- Patch #1739468: Directories and zipfiles containing a __main__.py
8692 file can now be directly executed by passing their name to the
8693 interpreter. The directory/zipfile is automatically inserted as the
8694 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008695
Georg Brandl3ee81df2008-05-17 18:14:43 +00008696- Issue #1265: Fix a problem with sys.settrace, if the tracing
8697 function uses a generator expression when at the same time the
8698 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008699
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008700- sets and frozensets now have an isdisjoint() method.
8701
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008702- optimize the performance of builtin.sum().
8703
Neal Norwitz44f326e2007-10-05 05:29:17 +00008704- Fix warnings found by the new version of the Coverity checker.
8705
Georg Brandl21e99f42010-03-07 15:23:59 +00008706- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008707 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8708 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008709
Georg Brandl3ee81df2008-05-17 18:14:43 +00008710- Issue #1686386: Tuple's tp_repr did not take into account the
8711 possibility of having a self-referential tuple, which is possible
8712 from C code. Nor did object's tp_str consider that a type's tp_str
8713 could do something that could lead to an inifinite recursion.
8714 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8715 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008716
Georg Brandl3ee81df2008-05-17 18:14:43 +00008717- Issue #1164: It was possible to trigger deadlock when using the
8718 'print' statement to write to a file since the GIL was not released
8719 as needed. Now PyObject_Print() does the right thing along with
8720 various tp_print implementations of the built-in types and those in
8721 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008722
Georg Brandl3ee81df2008-05-17 18:14:43 +00008723- Issue #1147: Exceptions were directly allowing string exceptions in
8724 their throw() method even though string exceptions no longer
8725 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008726
Georg Brandl3ee81df2008-05-17 18:14:43 +00008727- Issue #1096: Prevent a segfault from getting the repr of a very
8728 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008729
Brett Cannon1e534b52007-09-07 04:18:30 +00008730- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008731 PyObject_Call() never calling back out to Python code to trigger
8732 recursion depth updates/checks. Required the creation of a static
8733 RuntimeError instance in case normalizing an exception put the
8734 recursion check value past its limit. Fixes crashers
8735 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008736
Georg Brandl3ee81df2008-05-17 18:14:43 +00008737- Patch #1031213: Decode source line in SyntaxErrors back to its

8741 with %G.
8742
Georg Brandl3ee81df2008-05-17 18:14:43 +00008743- Prevent expandtabs() on string and unicode objects from causing a
8744 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00008745
Georg Brandl3ee81df2008-05-17 18:14:43 +00008746- Issue #1733488: Fix compilation of bufferobject.c on AIX.

Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008754- Add -3 option to the interpreter to warn about features that are
8755 deprecated and will be changed/removed in Python 3.0.
8756
Georg Brandl2134e752007-05-21 20:34:16 +00008757- Patch #1686487: you can now pass any mapping after '**' in function
8758 calls.
8759
Collin Winter62903052007-05-18 23:11:24 +00008760- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008761 "except E as target:". This is to provide forwards compatibility
8762 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008763
Brett Cannon229cee22007-05-05 01:34:02 +00008764- Deprecate BaseException.message as per PEP 352.
8765
Georg Brandl3ee81df2008-05-17 18:14:43 +00008766- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008767 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008768
Vinay Sajip8549ce32007-05-06 17:53:37 +00008769- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008770 setting a plain string, ie don't expand to single letter identifiers.
8771
Raymond Hettinger13936692007-04-11 18:40:58 +00008772- Request #1191699: Slices can now be pickled.
8773
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008774- Request #1193128: str.translate() now allows a None argument for
8775 translations that only remove characters without re-mapping the
8776 remaining characters.
8777
Georg Brandl5cb76c12007-03-21 09:00:39 +00008778- Patch #1682205: a TypeError while unpacking an iterable is no longer
8779 masked by a generic one with the message "unpack non-sequence".
8780
Neal Norwitzaa754b72007-03-21 06:39:48 +00008781- Remove unused file Python/fmod.c.
8782
Guido van Rossum143b5642007-03-23 04:58:42 +00008783- Bug #1683368: The object.__init__() and object.__new__() methods are
8784 now stricter in rejecting excess arguments. The only time when
8785 either allows excess arguments is when it is not overridden and the
8786 other one is. For backwards compatibility, when both are
8787 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008788 warning later). Also, type.__init__() insists on the same signature
8789 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008790
Georg Brandl3ee81df2008-05-17 18:14:43 +00008791- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8792 object to complex using its __complex__() method before falling back
8793 to the __float__() method. Therefore, the functions in the cmath
8794 module now can operate on objects that define a __complex__()
8795 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008796
Georg Brandl3ee81df2008-05-17 18:14:43 +00008797- Patch #1623563: allow __class__ assignment for classes with
8798 __slots__. The old and the new class are still required to have the
8799 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008800

8805 ``object.__reduce_ex__()`` is called with an object that is faking
8806 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00008807
Georg Brandl3ee81df2008-05-17 18:14:43 +00008808- Patch #1680015: Don't modify __slots__ tuple if it contains an

8812
Georg Brandl7b9c5552007-03-12 14:30:05 +00008813- Bug #1678647: write a newline after printing an exception in any
8814 case, even when converting the value to a string failed.
8815
Georg Brandl871f1bc2007-03-12 13:17:36 +00008816- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008817 its argument, if it exists. If not, it will work like before. This
8818 allows customizing the output of dir() in the presence of a
8819 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00008820
Collin Winter276887b2007-03-12 16:11:39 +00008821- Patch #922167: Python no longer segfaults when faced with infinitely
8822 self-recursive reload() calls (as reported by bug #742342).
8823
Georg Brandl3ee81df2008-05-17 18:14:43 +00008824- Patch #1675981: remove unreachable code from ``type.__new__()``
8825 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008827- Patch #1491866: change the complex() constructor to allow
8828 parthensized forms. This means complex(repr(x)) now works instead of
8829 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008830
Georg Brandlaa2321b2007-03-07 00:40:28 +00008831- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008832 makes the filenames the warning module prints much more sensible
8833 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008834
Georg Brandl49aafc92007-03-07 00:34:46 +00008835- Variant of patch #697613: don't exit the interpreter on a SystemExit
8836 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00008837 variable is given, but break into the interactive interpreter just
8838 like on other exceptions or normal program exit.

8844 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00008845
Georg Brandl0fca97a2007-03-05 22:28:08 +00008846- Patch #1674228: when assigning a slice (old-style), check for the
8847 sq_ass_slice instead of the sq_slice slot.
8848
Georg Brandl3ee81df2008-05-17 18:14:43 +00008849- When printing an unraisable error, don't print exceptions. before
8850 the name. This duplicates the behavior whening normally printing
8851 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00008852
Georg Brandl3ee81df2008-05-17 18:14:43 +00008853- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00008859- Bug #1377858: Fix the segfaulting of the interpreter when an object
8860 created a weakref on itself during a __del__ call for new-style
8861 classes (classic classes still have the bug).
Brett Cannonf5bee302007-01-23 23:21:22 +00008862
Martin v. Löwis6c5c5022007-01-23 21:11:47 +00008863- Bug #1579370: Make PyTraceBack_Here use the current thread, not the

Georg Brandl2c1375c2006-10-12 11:27:59 +00008901- Bug #1545497: when given an explicit base, int() did ignore NULs
8902 embedded in the string to convert.
8903
Georg Brandl846f73a2006-10-08 07:11:54 +00008904- Bug #1569998: break inside a try statement (outside a loop) is now
8905 recognized and rejected.
8906

8910 were fixed to not rely on undefined behaviour of the C compiler
8911 anymore.

8915
Georg Brandl5d59c092006-09-30 08:43:30 +00008916- Patch #1567691: super() and new.instancemethod() now don't accept

Georg Brandl4e933132006-09-06 20:05:58 +00008934- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
8935 Also make sure that every exception class has __module__ set to

Neal Norwitzdac090d2006-09-05 03:53:08 +00008951- Bug #1520864: unpacking singleton tuples in list comprehensions and
Georg Brandl3ee81df2008-05-17 18:14:43 +00008952 generator expressions (x for x, in ... ) works again. Fixing this
8953 problem required changing the .pyc magic number. This means that
8954 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009754- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9755 with RFC 3207 and forgets any knowledge obtained from the server not
9756 obtained from the TLS negotiation itself. Patch contributed by Bill
9757 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009758
Georg Brandl3ee81df2008-05-17 18:14:43 +00009759- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009760 that the SMTP.starttls() caller no longer needs to call ehlo()
9761 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009762 does not claim to support starttls. Adds the
9763 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

9844 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9845 silently miscode subclasses of those types. Now, it raises a
9846 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009847

Georg Brandl3ee81df2008-05-17 18:14:43 +00009862 time so that opening a database previously created with the DB_DUP
9863 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9864 opens. Specifically: dictionary assignment to a DB object will
9865 replace all values for a given key when the database allows
9866 duplicate values. DB users should use DB.put(k, v) when they want
9867 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009868

9874 characters with ASCII value less than 32. Also, it correctly quotes
9875 dots only if they occur on a single line, as opposed to the previous
9876 behavior of quoting dots if they are the second character of any
9877 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009878

10219 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
10220 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010221
10222- Patch #1720595: add T_BOOL to the range of structmember types.
10223
10224- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
10225 ``PyFloat_GetInfo()`` to the float API.
10226
Georg Brandl3ee81df2008-05-17 18:14:43 +000010227- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
10228 of w# format code incorrectly truncated the length to an int, even
10229 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10230 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010231
Georg Brandl3ee81df2008-05-17 18:14:43 +000010232- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
10233 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010234
Georg Brandl3ee81df2008-05-17 18:14:43 +000010235- PEP 3123: Provide forward compatibility with Python 3.0, while
10236 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
10237 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010238
Georg Brandl3ee81df2008-05-17 18:14:43 +000010239- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
10240 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010241
10242- Patch #1733960: Allow T_LONGLONG to accept ints.
10243
10244- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
10245
Christian Heimes000a0742008-01-03 22:16:32 +000010246- Added a new API function ``PyImport_ImportModuleNoBlock``.
10247
Georg Brandl6caad7d2008-01-26 14:19:22 +000010248- Bug #1637022: Prefix AST symbols with _Py_.
10249
10250- Fix some leftovers from the conversion from int to Py_ssize_t
10251 (relevant to strings and sequences of more than 2**31 items).
10252
10253- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10254 outside of pystate.c and should not be necessary.
10255
Georg Brandl3ee81df2008-05-17 18:14:43 +000010256- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10257 absolute imports. In earlier versions they might have used relative
10258 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010259
Georg Brandl3ee81df2008-05-17 18:14:43 +000010260- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10261 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010262
Georg Brandl3ee81df2008-05-17 18:14:43 +000010263- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
10264 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010269- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10270 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10271 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10272 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010273
Georg Brandl3ee81df2008-05-17 18:14:43 +000010274- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
10275 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010286- Removed the macfs module. It had been deprecated since Python 2.5.
10287 This lead to the deprecation of macostools.touched() as it relied
10288 solely on macfs and was a no-op under OS X.
