Terry Jan Reedya3ce2e52015-11-21 13:18:50 -0500331- Issue 15348: Stop the debugger engine (normally in a user process)
332 before closing the debugger window (running in the IDLE process).
333 This prevents the RuntimeErrors that were being caught and ignored.
334
335- Issue #24455: Prevent IDLE from hanging when a) closing the shell while the
336 debugger is active (15347); b) closing the debugger with the [X] button
337 (15348); and c) activating the debugger when already active (24455).
338 The patch by Mark Roseman does this by making two changes.
339 1. Suspend and resume the gui.interaction method with the tcl vwait
340 mechanism intended for this purpose (instead of root.mainloop & .quit).
341 2. In gui.run, allow any existing interaction to terminate first.
342
343- Change 'The program' to 'Your program' in an IDLE 'kill program?' message
344 to make it clearer that the program referred to is the currently running

Terry Jan Reedy1b6333a2015-10-04 01:14:45 -0400361- Issue #24820: IDLE now has an 'IDLE Dark' built-in text color theme.
362 It is more or less IDLE Classic inverted, with a cobalt blue background.
363 Strings, comments, keywords, ... are still green, red, orange, ... .
Terry Jan Reedya3ce2e52015-11-21 13:18:50 -0500364 To use it with IDLEs released before November 2015, hit the
365 'Save as New Custom Theme' button and enter a new name,
366 such as 'Custom Dark'. The custom theme will work with any IDLE
367 release, and can be modified.

Terry Jan Reedy0eb8f012015-09-20 23:21:17 -0400417 It looks better than help.txt and will better document Idle as released.
Terry Jan Reedy4dd78872015-09-21 19:28:18 -0400418 The tkinter html viewer that works for this file was written by Mark Roseman.

1806--------
1807
1808- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
1809 and later systems as is currently done for Python 3.x installers.
1810 For 2.7.7 only, we will provide three installers:
1811 the legacy deprecated 10.3+ 32-bit-only format;
1812 the newer 10.5+ 32-bit-only format;
1813 and the unchanged 10.6+ 64-/32-bit format.
1814 Although binary installers will no longer be available from
1815 python.org as of 2.7.8, it will still be possible to build from
1816 source on 10.3.9 and 10.4 systems if necessary.
1817 See Mac/BuildScript/README.txt for more information.

Ned Deily8e60f6e2013-05-30 00:14:29 -07002132- Issue #18098: The deprecated OS X Build Applet.app fails to build on
2133 OS X 10.8 systems because the Apple-deprecated QuickDraw headers have

2140 64-bit/32-bit installer for 10.6+. It is no longer necessary
2141 to install a third-party version of Tcl/Tk 8.5 to work around the
2142 problems in the Apple-supplied Tcl/Tk 8.5 shipped in OS X 10.6
2143 and later releases.

Ned Deilyf84b5312013-10-25 00:44:46 -07002145- Issue #19019: Change the OS X installer build script to use CFLAGS instead
2146 of OPT for special build options. By setting OPT, some compiler-specific
2147 options like -fwrapv were overridden and thus not used, which could result
2148 in broken interpreters when building with clang.

3199 32-bit-only installer Pythons on systems with Xcode 4 (currently
3200 OS X 10.8, 10.7, and optionally 10.6).
3201 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
3202 * Since Xcode 4 removes ppc support, extension module builds now
3203 check for ppc compiler support and by default remove ppc and
3204 ppc64 archs when they are not available.
3205 * Extension module builds now revert to using system installed
3206 headers and libs (/usr and /System/Library) if the SDK used
3207 to build the interpreter is not installed or has moved.
3208 * Try to avoid building extension modules with deprecated
3209 and problematic Apple llvm-gcc compiler. If original compiler
3210 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01003574- Issue #12973: Fix overflow checks that invoked undefined behaviour in
3575 int.__pow__. These overflow checks were causing int.__pow__ to produce
3576 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01003577 compiler optimizing the check away. Also fix similar overflow checks
3578 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
3579 bugs caused test failures with recent versions of Clang.

Florent Xiclunac2279652012-02-12 14:49:03 +01003647- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01003648 has left two versions of customize_compiler, the original in
3649 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01003654- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
3655 Distutils-based packages with C extension modules may fail because
3656 Apple has removed gcc-4.2, the version used to build python.org
3657 64-bit/32-bit Pythons. If the user does not explicitly override
3658 the default C compiler by setting the CC environment variable,
3659 Distutils will now attempt to compile extension modules with clang
3660 if gcc-4.2 is required but not found. Also as a convenience, if
3661 the user does explicitly set CC, substitute its value as the default
3662 compiler in the Distutils LDSHARED configuration variable for OS X.
3663 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
3664 SDK, neither of which are available in Xcode 4. This change does not
3665 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003915- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3916 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3917 interpreter process. This could cause failures in non-Distutils subprocesses
3918 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003919 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003920 deployment target only in the environment of each build subprocess. It is
3921 still possible to globally override the default by setting
3922 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3923 greater or equal to the default value, the value with which the interpreter
3924 was built.

3953 updating the check interval, so if the user decreases the check interval,
3954 the ticker doesn't have to wind down to zero from the old starting point
3955 before the new interval takes effect. And if the user increases the
3956 interval, it makes sure the new limit takes effect right away rather have an
3957 early task switch before recognizing the new interval.

4955 This prevents user-created self-referencing ordered dictionaries from
4956 becoming permanently uncollectable GC garbage. The downside is that
4957 removing __del__ means that the internal doubly-linked list has to wait for
4958 GC collection rather than freeing memory immediately when the refcnt drops
4959 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00005417- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
5418 start byte and the continuation byte(s) are now considered invalid, instead
5419 of the number of bytes specified by the start byte.
5420 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
5421 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
5422 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
5423 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00005431- Issue #8748: Fix two issues with comparisons between complex and integer
5432 objects. (1) The comparison could incorrectly return True in some cases
5433 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
5434 (2) The comparison raised an OverflowError for large integers, leading
5435 to unpredictable exceptions when combining integers and complex objects
5436 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00005438- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00005575- Issue #1533: Fix inconsistency in range function argument processing: any
5576 non-float non-integer argument is now converted to an integer (if possible)
5577 using its __int__ method. Previously, only small arguments were treated this
5578 way; larger arguments (those whose __int__ was outside the range of a C long)
5579 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00005808- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00005809 on 64-bit machines. The shift count for either left or right shift is
5810 permitted to be up to sys.maxsize.
5811
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00005812- Ensure that tokenization of identifiers is not affected by locale.
5813
Georg Brandlfee0f442010-05-22 21:26:21 +00005814- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00005815
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00005816- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
5817
Georg Brandlfee0f442010-05-22 21:26:21 +00005818- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
5819 with a non-empty format string. This is an effort to future-proof user
5820 code. If a derived class does not currently implement __format__ but later
5821 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00005822 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00005823 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00005824
Antoine Pitroua57df2c2010-03-31 21:32:15 +00005825- Issue #8268: Old-style classes (not just instances) now support weak
5826 references.
5827
Georg Brandlfee0f442010-05-22 21:26:21 +00005828- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
5829 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00005830

5837
Victor Stinner66644262010-03-10 22:30:19 +00005838- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00005839 (SIGINT). If an error occurs while importing the site module, the error is
5840 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00005841 module.

5849
Antoine Pitrouf9de5342010-04-05 21:35:07 +00005850- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00005851 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and

5855
Georg Brandlfee0f442010-05-22 21:26:21 +00005856- Issue #8257: The Decimal construct now accepts a float instance directly,
5857 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00005858
5859 >>> Decimal(1.1)
5860 Decimal('1.100000000000000088817841970012523233890533447265625')
5861
Raymond Hettinger34c35b22010-04-03 10:22:00 +00005862- collections.Counter() now supports a subtract() method.
5863
Georg Brandlfee0f442010-05-22 21:26:21 +00005864- The functools module now has a total_ordering() class decorator to simplify
5865 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00005866
Georg Brandlfee0f442010-05-22 21:26:21 +00005867- The functools module also adds cmp_to_key() as a tool to transition old-style
5868 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00005869
Georg Brandlfee0f442010-05-22 21:26:21 +00005870- Issue #8294: The Fraction constructor now accepts Decimal and float instances
5871 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00005872
Georg Brandlfee0f442010-05-22 21:26:21 +00005873- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
5874 InvalidOperation instead of returning False. (Comparisons involving a quiet
5875 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
5876 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00005877
Georg Brandlfee0f442010-05-22 21:26:21 +00005878- Issue #2531: Comparison operations between floats and Decimal instances now
5879 return a result based on the numeric values of the operands; previously they
5880 returned an arbitrary result based on the relative ordering of id(float) and
5881 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00005882
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00005883- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00005884 argument `-` which tells it to read files to compile from stdin. Each line is
5885 read on demand and the named file is compiled immediately. (Original patch by
5886 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00005887
Georg Brandlfee0f442010-05-22 21:26:21 +00005888- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
5889 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00005891- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
5892 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00005893 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00005894
Georg Brandlfee0f442010-05-22 21:26:21 +00005895- Comparisons using one of <, <=, >, >= between a complex instance and a
5896 Fractions instance now raise TypeError instead of returning True/False. This
5897 makes Fraction <=> complex comparisons consistent with int <=> complex, float
5898 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00005899

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00005909- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00005910 didn't support chflags() (for example ZFS under FreeBSD). The error is now
5911 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00005912
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00005913- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
5914 deprecated.
5915
Georg Brandlfee0f442010-05-22 21:26:21 +00005916- Issue #7860: platform.uname now reports the correct 'machine' type when Python
5917 is running in WOW64 mode on 64 bit Windows.

Georg Brandlfee0f442010-05-22 21:26:21 +00005954 for ``TimedRotatingFileHandler`` by using the modification time of an existing
5955 log file to compute the next rollover time. If the log file does not exist,
5956 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00005957

Georg Brandlba83f822010-03-14 09:50:54 +00005966- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
5967 a base64 transfer-encoded payload *after* decoding it; it no longer does.
5968 This is a behavior change, so email's minor version number is now bumped, to
5969 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00005997- Issue #8300: When passing a non-integer argument to struct.pack with any
5998 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00006002- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
6003 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
6004 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00006005 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
6006 inconsistent: __int__ was used for some integer codes but not for others, and
6007 the set of integer codes for which it was used differed between native packing
6008 and standard packing.)

6270 including:
Mark Dickinson8efef5c2010-01-12 22:23:56 +00006271
Georg Brandlba83f822010-03-14 09:50:54 +00006272 (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
6273 strings,
6274 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
6275 numeric strings corresponding to subnormal values,
6276 (3) a memory leak for some values large enough to cause overflow, and
6277 (4) a number of flaws that could lead to incorrectly rounded results.

Georg Brandlba83f822010-03-14 09:50:54 +00006316 file position when calling `truncate()`. It would previously change the file
6317 position to the given argument, which goes against the tradition of

6412Core and Builtins
6413-----------------
6414
Georg Brandlba83f822010-03-14 09:50:54 +00006415- The ``__complex__()`` method is now looked up on the class of instances to
6416 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00006418- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
6419 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
6420
Mark Dickinson1b34d252010-01-01 17:27:30 +00006421- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00006422 DeprecationWarning when passed a float argument where an integer was expected.
6423 These functions and methods now raise TypeError instead. The majority of the
6424 effects of this change are in the extension modules, but some core functions
6425 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
6426 and many unicode/str methods.

6437 used to drop the time part of the result.
6438
Georg Brandlba83f822010-03-14 09:50:54 +00006439- Issue #1811: Improve accuracy and cross-platform consistency for true division
6440 of integers: the result of a/b is now correctly rounded for ints a and b (at
6441 least on IEEE 754 platforms), and in particular does not depend on the
6442 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00006443
Georg Brandlba83f822010-03-14 09:50:54 +00006444- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the

Ronald Oussoren92919a62009-12-24 13:30:58 +00006449 executables on OSX.
6450
Georg Brandlba83f822010-03-14 09:50:54 +00006451 These executables now work properly with the arch(1) command: ``arch -ppc
6452 python`` will start a universal binary version of python in PPC mode (unlike
6453 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00006608- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
6609 decimal string that's guaranteed to round back to x under correct rounding
6610 (with round-half-to-even rounding mode). Previously it gave a string based on
6611 rounding x to 17 decimal digits. repr(x) for a complex number behaves
6612 similarly. On platforms where the correctly-rounded strtod and dtoa code is
6613 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006614
Georg Brandlba83f822010-03-14 09:50:54 +00006615- Issue #7117: On almost all platforms: float-to-string and string-to-float
6616 conversions within Python are now correctly rounded. Places these conversions
6617 occur include: str for floats and complex numbers; the float and complex
6618 constructors; old-style and new-style numeric formatting; serialization and
6619 deserialization of floats and complex numbers using marshal, pickle and json;
6620 parsing of float and imaginary literals in Python code; Decimal-to-float
6621 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006622
Georg Brandlba83f822010-03-14 09:50:54 +00006623 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
6624 providing correctly-rounded strtod and dtoa C functions. This code is
6625 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
6626 the C compiler. There may be a small number of platforms on which correct
6627 operation of this code cannot be guaranteed, so the code is not used: notably,
6628 this applies to platforms where the C double format is not IEEE 754 binary64,
6629 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
6630 and Python's configure script is unable to determine how to change the FPU
6631 precision. On these platforms conversions use the platform strtod and dtoa,
6632 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00006634- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
6635 uses the correctly-rounded string <-> float conversions described above (when
6636 available), and so produces correctly rounded results that will display nicely
6637 under the float repr. There are two related small changes: (1) round now
6638 accepts any class with an ``__index__()`` method for its second argument (but
6639 no longer accepts floats for the second argument), and (2) an excessively
6640 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
6641 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00006784 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
6785 (2) parsing of strings representing infinities and nans was locale aware; and
6786 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00006788- Issue #5920: For ``float.__format__()``, change the behavior with the empty
6789 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
6790 but with at least one decimal point and with a default precision
6791 of 12. Previously, the behavior the same but with a default precision of 6.
6792 This more closely matches ``str()``, and reduces surprises when adding
6793 alignment flags to the empty presentation type. This also affects the new
6794 complex.__format__ in the same way.
6795
6796- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00006977- Issue #4445: Replace ``sizeof(PyStringObject)`` with
6978 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
6979 instances. On a typical machine this saves 3 bytes of memory (on average) per
6980 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00006982- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

6991
Georg Brandlba83f822010-03-14 09:50:54 +00006992- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
6993 file objects with closefd=False. The file descriptor is still kept open but
6994 the file object behaves like a closed file. The ``FileIO`` object also got a
6995 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00007018- On windows, ``os.chdir()`` given unicode was not working if

7020 this code path is really executed because I cannot move to such directory on
7021 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00007023- Issue #4069: When ``set.remove(element)`` is used with a set element, the
7024 element is temporarily replaced with an equivalent frozenset. But the
7025 eventual KeyError would always report the empty ``frozenset()`` as the missing
7026 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00007046- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
7047 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
7048 step. This avoids problems with counting UTF-8 bytes that ignores the effect
7049 of using the replace error handler in PyUnicode_DecodeUTF8().
7050
Walter Dörwald726ba8e2009-05-06 14:32:35 +00007051- Issue #3739: The unicode-internal encoder now reports the number of characters

7053
Georg Brandlba83f822010-03-14 09:50:54 +00007054- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
7055 allocator will be automatically disabled when running under Valgrind. This
7056 gives improved memory leak detection when running under Valgrind, while taking
7057 advantage of pymalloc at other times.

8248 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
8249 neither __int__ nor __long__, TypeError used to be raised (with a
8250 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
8251 struct.error in other cases.

8254 argument with an __int__ method can be packed, but use of this feature

8447
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00008448- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
8449 PyString_FromFormat or PyErr_Format to display size_t values. The macro
8450 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
8451 ``printf`` function, whereas PyString_FromFormat has an independent
8452 implementation and uses "%zd" on all platforms for size_t values.
8453 This makes a difference on win64, where ``printf`` needs "%Id" to display
8454 64bit values.

8460 object; previously an int would be returned for small values. the __long__
8461 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00008471 was correctly parsed but parsing of subsequent arguments failed.
8472
Vinay Sajip35e3b032008-09-01 14:33:59 +00008473- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00008474 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
8475 mechanism. In the process, fix a bug where isinstance() and issubclass(),
8476 when given a tuple of classes as second argument, were looking up
8477 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
8478 type object.

Guido van Rossumf8402962008-08-20 15:01:50 +00008625- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
8626 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
8627 extensions do not automatically benefit from the class attribute
8628 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
8629 to their tp_flags field if they care. This is a backwards
8630 compatibility feature; in 3.0, all types will use the cache by
8631 default.
8632
Benjamin Petersonf647dc12008-08-20 01:27:30 +00008633- Keyword arguments can now follow starred arguments. (``f(a, *args,

8644 object was stored in the freelist.
8645
Mark Dickinsonb6467572008-08-04 21:30:09 +00008646- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
8647 ValueError consistently across platforms.
8648
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00008649- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
8650 (64bit Unix, for example), unichr() would truncate its argument and return
8651 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
8652
Neal Norwitze7d8be82008-07-31 17:17:14 +00008653- Apply security patches from Apple.
8654
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00008655- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
8656 PyErr_ExceptionMatches returns 0 when an exception occurs there.
8657
Antoine Pitrou92f82162008-07-25 22:22:08 +00008658- Issue #1819: function calls with several named parameters are now on
8659 average 35% faster (as measured by pybench).
8660
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00008661- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
8662 the python debugger steps into a class statement: the free variables (local
8663 variables defined in an outer scope) would be deleted from the outer scope.
8664
Gregory P. Smith0470bab2008-07-22 04:46:32 +00008665- Issue #2620: Overflow checking when allocating or reallocating memory
8666 was not always being done properly in some python types and extension
8667 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
8668 all been updated to perform better checks and places in the code that
8669 would previously leak memory on the error path when such an allocation
8670 failed have been fixed.

8676
Benjamin Petersone977ad42008-08-20 01:42:01 +00008677- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
8678 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
8679
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00008680- Issue #2234: distutils failed for some versions of the cygwin compiler. The
8681 version reported by these tools does not necessarily follow the python
8682 version numbering scheme, so the module is less strict when parsing it.
8683
Nick Coghlanf70385a2008-08-18 12:42:46 +00008684- Issue #2235: Added Py3k warnings for types which will become unhashable
8685 under the stricter __hash__ inheritance rules in 3.0. Several types
8686 which did not meet the rules for hash invariants and were already
8687 unhashable in 3.0 have now been explicitly flagged as unhashable in
8688 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
8689 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
8690
Brett Cannon88f801d2008-08-18 00:46:22 +00008691- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
8692 imported into the module but exposed as part of the module's API.

Brett Cannonbf3157b2008-08-14 05:00:03 +00008722- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
8723 since mimetools itself is deprecated. Because modules are cached, all
8724 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
8725

8735 a MemoryError rather than silently stop the iteration.
8736
Guido van Rossum59ce9012008-08-09 14:55:34 +00008737- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
8738 to _sre.compile() will now be rejected. This should not affect anybody
8739 since the re.compile() function never generates invalid re-bytecode.

8743 it wasn't initialized during instantiation.
8744
Brett Cannon3aa2a492008-08-06 22:28:09 +00008745- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
8746 the reload() built-in has been removed.
8747
Brett Cannon7e30b672008-08-04 21:52:25 +00008748- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00008760 asking for a specific length. This problem only affected files opened
8761 using the new "io" module, not the built-in open() function.

8787 file name rather than a ZipInfo instance, so files are extracted with
8788 mode 0600 rather than 000 under Unix.
8789
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00008790- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

Nick Coghlan6e8fef02008-08-18 13:14:22 +00008802- Issue #2235: the C API function PyObject_HashNotImplemented and its
8803 interaction with the tp_hash slot (added in 2.6b2) are now documented
8804
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00008805- Issue #643841: The language reference now provides more detailed
8806 coverage of the lookup process for special methods. The disclaimers
8807 regarding lack of coverage of new-style classes have also been
8808 removed, since the coverage is now fairly reasonable.

8812================================
8813
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00008814*Release date: 17-Jul-2008*
8815
Raymond Hettingere3ae6552008-06-20 04:18:15 +00008816Core and Builtins
8817-----------------
8818
Georg Brandl3e483f62008-07-16 22:57:41 +00008819- Issue #3156: Fix inconsistent behavior of the bytearray type: all
8820 its methods now allow for items objects that can be converted to
8821 an integer using operator.index().
8822
Mark Dickinson64b7e502008-07-16 09:40:03 +00008823- Issue #3360: Fix incorrect parsing of '020000000000.0', which
8824 produced a ValueError instead of giving the correct float.
8825
Eric Smitha5fa5a22008-07-16 00:11:49 +00008826- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
8827 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
8828
Mark Dickinson7103aa42008-07-15 19:08:33 +00008829- Issue #3008: the float type has a new instance method 'float.hex'
8830 and a new class method 'float.fromhex' to convert floating-point
8831 numbers to and from hexadecimal strings, respectively.
8832
Nick Coghlan6d6bd442008-07-15 15:40:22 +00008833- Issue #2235: __hash__ is once again inherited by default. To allow
8834 collections.Hashable to remain meaningful in the presence of the
8835 default hash implementation (object.__hash__), it is now possible
8836 to explicit block inheritance of hash by setting __hash__=None at
8837 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8838 level.
8839
Nick Coghlanb028f502008-07-13 14:52:36 +00008840- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8841 the parent module cannot be found while performing an absolute import.
8842 This means that an incorrectly defined __package__ attribute will
8843 now only prevent relative imports in that module rather than causing
8844 all imports from that module to fail.
8845
Nick Coghlan14ff9942008-07-08 14:21:42 +00008846- Issue #2517: Allow unicode messages in Exceptions again by correctly
8847 bypassing the instance dictionary when looking up __unicode__ on
8848 new-style classes.
8849
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00008850- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
8851 set to a custom object whose write() method happens to install
8852 another file in sys.stdout.
8853
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00008854- Issue #3088: Corrected a race condition in classes derived from
8855 threading.local: the first member set by a thread could be saved in
8856 another thread's dictionary.
8857
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008858- Issue #3004: Minor change to slice.indices(): the start and stop
8859 arguments are now treated identically, making the behaviour easier
8860 to describe and understand. For example, slice(None, -10,
8861 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8862 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8863 10, -1).
8864
Georg Brandl278fc502008-07-19 12:46:12 +00008865- Issue #3219: Calling a function with repeated keyword arguments,
8866 f(a=2, a=23), would not cause a syntax error. This was a regression
8867 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00008868
Georg Brandl278fc502008-07-19 12:46:12 +00008869- Issue #2862: Make int and float freelist management consistent with
8870 other freelists. Changes their CompactFreeList apis into
8871 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00008872

8874-------
8875
Thomas Heller57adf222008-08-14 19:10:48 +00008876- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
8877 api functions without holding the GIL, which could lead to a fatal
8878 error when they failed.
8879
Martin v. Löwisaabf4042008-08-02 07:20:25 +00008880- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

8889 ForkingPickler.register() to resolve conflict with ctypes.
8890
Vinay Sajip51e65192008-07-18 09:01:10 +00008891- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00008893- Issue #3313: Fixed a crash when a failed dlopen() call does not set
8894 a valid dlerror() message.
8895
Thomas Heller2bad6572008-07-15 17:19:50 +00008896- Issue #3258: Fixed a crash when a ctypes POINTER type to an
8897 incomplete structure was created.
8898
Brett Cannon3d0b9f02008-07-13 01:15:07 +00008899- Issue #3339: dummy_thread.acquire() should not return None.

8902
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008903- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00008904
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008905- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
8906 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008907 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008908 content-length. The problem had been corrected in the 2.4 branch, but never
8909 merged into trunk.
8910
Georg Brandle78fbcc2008-07-05 10:13:36 +00008911- Issue #2663: add filtering capability to shutil.copytree().

9312
Ronald Oussoren5640ce22008-06-05 12:58:24 +00009313- On MacOS X it is now possible to install the framework in 64-bit
9314 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00009315 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00009316
9317 This is controlled by the configure argument ``--with-universal-archs``:
9318
9319 - ``--with-universal-archs=all``: install 4-way universal
9320
9321 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
9322
9323 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
9324
9325 This option should be used in combination with ``--enable-universalsdk=``.
9326
9327 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 +00009376- Issue #1631171: Re-implement the 'warnings' module in C (the
9377 original Python code has been kept as backup). This will allow for
9378 using the 'warning's machinery in such places as the parser where
9379 use of pure Python code is not possible. Both the ``showarning()``
9380 and ``formatwarning()`` gain an optional 'line' argument which is
9381 not called by default for backwards-compatibility reasons. Setting
9382 ``warnings.showwarning()`` to an implementation that lacks support
9383 for the ``line`` argument will raise a DeprecationWarning.

9407
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00009408- The getpass module has been improved on Unix. It now uses /dev/tty
9409 by default and uses stderr instead of stdout. A GetPassWarning is
9410 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009425- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00009426 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00009446- Issue #2550: The approach used by client/server code for obtaining
9447 ports to listen on in network-oriented tests has been refined in an
9448 effort to facilitate running multiple instances of the entire
9449 regression test suite in parallel without issue.
9450 test_support.bind_port() has been fixed such that it will always
9451 return a unique port -- which wasn't always the case with the
9452 previous implementation, especially if socket options had been set
9453 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
9454 new implementation of bind_port() will actually raise an exception
9455 if it is passed an AF_INET/SOCK_STREAM socket with either the
9456 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
9457 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
9458 the socket it's been passed. This currently only applies to
9459 Windows. This option prevents any other sockets from binding to the
9460 host/port we've bound to, thus removing the possibility of the
9461 'non-deterministic' behaviour, as Microsoft puts it, that occurs
9462 when a second SOCK_STREAM socket binds and accepts to a host/port
9463 that's already been bound by another socket. The optional preferred
9464 port parameter to bind_port() has been removed. Under no
9465 circumstances should tests be hard coding ports!
9466
9467 test_support.find_unused_port() has also been introduced, which will
9468 pass a temporary socket object to bind_port() in order to obtain an
9469 unused port. The temporary socket object is then closed and
9470 deleted, and the port is returned. This method should only be used
9471 for obtaining an unused port in order to pass to an external program
9472 (i.e. the -accept [port] argument to openssl's s_server mode) or as
9473 a parameter to a server-oriented class that doesn't give you direct
9474 access to the underlying socket used.
9475
9476 Finally, test_support.HOST has been introduced, which should be used
9477 for the host argument of any relevant socket calls (i.e. bind and
9478 connect).

9753-----------------
9754
Fred Drakea8ee94b2008-03-01 02:45:07 +00009755- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00009756 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00009757
Georg Brandlad61bc82008-02-23 15:11:18 +00009758- Issue #2067: file.__exit__() now calls subclasses' close() method.
9759
9760- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00009761
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009762- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00009763 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00009764
Eric Smitha73fbe72008-02-23 03:09:44 +00009765- Added the future_builtins module, which contains hex() and oct().
9766 These are the PEP 3127 version of these functions, designed to be
9767 compatible with the hex() and oct() builtins from Python 3.0. They
9768 differ slightly in their output formats from the existing, unchanged
9769 Python 2.6 builtins. The expected usage of the future_builtins
9770 module is:
9771 from future_builtins import hex, oct
9772
Eric Smith7ef40bf2008-02-20 23:34:22 +00009773- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
9774 exponents for exponents with absolute value < 100. Follows C99
9775 standard. This is a change on Windows, which would use 3 digits.
9776 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
9777 so that any alterations it does to the resulting string will be
9778 available in stringlib/formatter.h (for float.__format__).
9779
Eric Smith5a3c1352008-02-19 13:21:56 +00009780- Implemented PEP 3101, Advanced String Formatting. This adds a new
9781 builtin format(); a format() method for str and unicode; a
9782 __format__() method to object, str, unicode, int, long, float, and
9783 datetime; the class string.Formatter; and the C API
9784 PyObject_Format().
9785
Georg Brandl3ee81df2008-05-17 18:14:43 +00009786- Fixed several potential crashes, all caused by specially crafted
9787 __del__ methods exploiting objects in temporarily inconsistent
9788 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00009789
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009790- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00009791 prevent a possible crash: an Abstract Base Class would try to access
9792 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00009793
Georg Brandl3ee81df2008-05-17 18:14:43 +00009794- Fixed repr() and str() of complex numbers with infinity or nan as
9795 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00009796
Georg Brandl3ee81df2008-05-17 18:14:43 +00009797- Clear all free lists during a gc.collect() of the highest generation
9798 in order to allow pymalloc to free more arenas. Python may give back
9799 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00009800
Georg Brandl3ee81df2008-05-17 18:14:43 +00009801- Issue #2045: Fix an infinite recursion triggered when printing a
9802 subclass of collections.defaultdict, if its default_factory is set
9803 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00009804
Christian Heimesf75dbef2008-02-08 00:11:31 +00009805- Fixed a minor memory leak in dictobject.c. The content of the free
9806 list was not freed on interpreter shutdown.
9807
Georg Brandl21e99f42010-03-07 15:23:59 +00009808- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00009809 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00009810
Georg Brandl3ee81df2008-05-17 18:14:43 +00009811- Patch #1953: Added ``sys._compact_freelists()`` and the C API
9812 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00009813 to compact the internal free lists of pre-allocted ints and floats.
9814
Georg Brandl3ee81df2008-05-17 18:14:43 +00009815- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
9816 calls. Python expected the return type int but the fork familie
9817 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00009818
Georg Brandl3ee81df2008-05-17 18:14:43 +00009819- Issue #1678380: Fix a bug that identifies 0j and -0j when they
9820 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00009821
Georg Brandl3ee81df2008-05-17 18:14:43 +00009822- Issue #2025: Add tuple.count() and tuple.index() methods to comply
9823 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00009824
Georg Brandl3ee81df2008-05-17 18:14:43 +00009825- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
9826 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00009827
Georg Brandl3ee81df2008-05-17 18:14:43 +00009828- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
9829 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00009830
Georg Brandl3ee81df2008-05-17 18:14:43 +00009831- Patch #1473257: generator objects gain a gi_code attribute. This is
9832 the same object as the func_code attribute of the function that
9833 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00009834
Georg Brandl3ee81df2008-05-17 18:14:43 +00009835- Issue #1920: "while 0" statements were completely removed by the
9836 compiler, even in the presence of an "else" clause, which is
9837 supposed to be run when the condition is false. Now the compiler
9838 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009839
Guido van Rossumeead05f2008-01-24 18:21:02 +00009840- A few crashers fixed: weakref_in_del.py (issue #1377858);
9841 loosing_dict_ref.py (issue #1303614, test67.py);
9842 borrowed_ref_[34].py (not in tracker).
9843
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00009844- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00009845 suppressed while an extension is loaded by calling SetErrorMode in
9846 dynload_win.c. The error is still reported properly.
9847
Georg Brandl3ee81df2008-05-17 18:14:43 +00009848- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009849 several extension methods and modules do not work without unicode
9850 support.
9851
Georg Brandl26543b12008-01-21 18:36:51 +00009852- Issue #1882: when compiling code from a string, encoding cookies in the
9853 second line of code were not always recognized correctly.
9854
Georg Brandl14404b62008-01-19 19:27:05 +00009855- Issue #1679: "0x" was taken as a valid integer literal.
9856
Georg Brandl6caad7d2008-01-26 14:19:22 +00009857- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009858 added.
9859
Christian Heimesc94e2b52008-01-14 04:13:37 +00009860- sys.float_info / PyFloat_GetInfo: The floating point information
9861 object was converted from a dict to a specialized structseq object.
9862
Georg Brandl3ee81df2008-05-17 18:14:43 +00009863- Patch #1816: Added sys.flags structseq. It exposes the status of
9864 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009865
Georg Brandl3ee81df2008-05-17 18:14:43 +00009866- Objects/structseq.c: Implemented new structseq representation. The
9867 patch makes structseqs (e.g. the return value of os.stat) more
9868 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009869
Georg Brandl3ee81df2008-05-17 18:14:43 +00009870- Patch #1700288: added a type attribute cache that caches method
9871 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00009872
Neal Norwitz3fc15b82008-01-10 05:42:58 +00009873- Bug #1776: __import__() no longer accepts filenames on any platform.
9874 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00009875
Georg Brandlaed6c662008-01-07 17:25:53 +00009876- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
9877
Georg Brandl3ee81df2008-05-17 18:14:43 +00009878- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
9879 envvar and sys.dont_write_bytecode attribute. All these can be set
9880 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00009881
Georg Brandl3ee81df2008-05-17 18:14:43 +00009882- Improve some exception messages when Windows fails to load an
9883 extension module. Now we get for example '%1 is not a valid Win32
9884 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00009885
Georg Brandl3ee81df2008-05-17 18:14:43 +00009886- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009888- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
9889 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00009890
Christian Heimes0a8143f2007-12-18 23:22:54 +00009891- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00009892 and INF. float("nan"), float("inf") and float("-inf") now work on
9893 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009894
Georg Brandl3ee81df2008-05-17 18:14:43 +00009895- Compiler now generates simpler and faster code for dictionary
9896 literals. The oparg for BUILD_MAP now indicates an estimated
9897 dictionary size. There is a new opcode, STORE_MAP, for adding
9898 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00009899
Georg Brandl3ee81df2008-05-17 18:14:43 +00009900- Issue #1638: %zd configure test fails on Linux.

9906 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00009907
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00009908- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00009909 SystemError.
9910
Nick Coghlanef01d822007-12-03 12:55:17 +00009911- PEP 366: Allow explicit relative imports when executing modules
9912 inside packages with the -m switch via a new module level
9913 __package__ attribute.
9914
Georg Brandl3ee81df2008-05-17 18:14:43 +00009915- Issue #1402: Fix a crash on exit, when another thread is still
9916 running, and if the deallocation of its frames somehow calls the
9917 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00009918

9928 file can now be directly executed by passing their name to the
9929 interpreter. The directory/zipfile is automatically inserted as the
9930 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00009931
Georg Brandl3ee81df2008-05-17 18:14:43 +00009932- Issue #1265: Fix a problem with sys.settrace, if the tracing
9933 function uses a generator expression when at the same time the
9934 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00009935
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00009936- sets and frozensets now have an isdisjoint() method.
9937
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00009938- optimize the performance of builtin.sum().
9939
Neal Norwitz44f326e2007-10-05 05:29:17 +00009940- Fix warnings found by the new version of the Coverity checker.
9941
Georg Brandl21e99f42010-03-07 15:23:59 +00009942- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009943 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9944 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009945
Georg Brandl3ee81df2008-05-17 18:14:43 +00009946- Issue #1686386: Tuple's tp_repr did not take into account the
9947 possibility of having a self-referential tuple, which is possible
9948 from C code. Nor did object's tp_str consider that a type's tp_str
9949 could do something that could lead to an inifinite recursion.
9950 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9951 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009952
Georg Brandl3ee81df2008-05-17 18:14:43 +00009953- Issue #1164: It was possible to trigger deadlock when using the
9954 'print' statement to write to a file since the GIL was not released
9955 as needed. Now PyObject_Print() does the right thing along with
9956 various tp_print implementations of the built-in types and those in
9957 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009958
Georg Brandl3ee81df2008-05-17 18:14:43 +00009959- Issue #1147: Exceptions were directly allowing string exceptions in
9960 their throw() method even though string exceptions no longer
9961 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00009962
Georg Brandl3ee81df2008-05-17 18:14:43 +00009963- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00009966- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009967 PyObject_Call() never calling back out to Python code to trigger
9968 recursion depth updates/checks. Required the creation of a static
9969 RuntimeError instance in case normalizing an exception put the
9970 recursion check value past its limit. Fixes crashers
9971 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00009972

Georg Brandl3ee81df2008-05-17 18:14:43 +00009987 __*__ attributes. (Some already existed, e.g., __doc__ and
9988 __name__.)

Georg Brandl3ee81df2008-05-17 18:14:43 +00009997 "except E as target:". This is to provide forwards compatibility
9998 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010002- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +000010003 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +000010004
Vinay Sajip8549ce32007-05-06 17:53:37 +000010005- When __slots__ are set to a unicode string, make it work the same as

Serhiy Storchaka16870742015-08-09 13:07:06 +030010010- Request #1193128: str.translate() now allows a None argument for
Raymond Hettinger4db5fe92007-04-12 04:10:00 +000010011 translations that only remove characters without re-mapping the
10012 remaining characters.
10013
Georg Brandl5cb76c12007-03-21 09:00:39 +000010014- Patch #1682205: a TypeError while unpacking an iterable is no longer

10018
Guido van Rossum143b5642007-03-23 04:58:42 +000010019- Bug #1683368: The object.__init__() and object.__new__() methods are
10020 now stricter in rejecting excess arguments. The only time when
10021 either allows excess arguments is when it is not overridden and the
10022 other one is. For backwards compatibility, when both are
10023 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +000010024 warning later). Also, type.__init__() insists on the same signature
10025 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +000010027- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
10028 object to complex using its __complex__() method before falling back
10029 to the __float__() method. Therefore, the functions in the cmath
10030 module now can operate on objects that define a __complex__()
10031 method.

Georg Brandl5240d742007-03-13 20:46:32 +000010047- Patch #1444529: the builtin compile() now accepts keyword arguments.
10048
Georg Brandl7b9c5552007-03-12 14:30:05 +000010049- Bug #1678647: write a newline after printing an exception in any
10050 case, even when converting the value to a string failed.
10051
Georg Brandl871f1bc2007-03-12 13:17:36 +000010052- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +000010053 its argument, if it exists. If not, it will work like before. This
10054 allows customizing the output of dir() in the presence of a
10055 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +000010056

10064 parthensized forms. This means complex(repr(x)) now works instead of
10065 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +000010066
Georg Brandlaa2321b2007-03-07 00:40:28 +000010067- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +000010068 makes the filenames the warning module prints much more sensible
10069 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +000010070

Georg Brandl0fca97a2007-03-05 22:28:08 +000010082- Patch #1674228: when assigning a slice (old-style), check for the

10084
Georg Brandl3ee81df2008-05-17 18:14:43 +000010085- When printing an unraisable error, don't print exceptions. before

10983 the first chunk fed to the decoder started with a BOM, but was
10984 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +000010985
Georg Brandl3ee81df2008-05-17 18:14:43 +000010986- The implementation of UnicodeError objects has been simplified

Georg Brandl3ee81df2008-05-17 18:14:43 +000010995- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +000010996 that the SMTP.starttls() caller no longer needs to call ehlo()
10997 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +000010998 does not claim to support starttls. Adds the
10999 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +000011042- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +000011043 works as expected. ``mmap.find`` also takes an optional ``end``

11080 complex, tuple, list, dict, set, and frozenset. Formerly, it would
11081 silently miscode subclasses of those types. Now, it raises a
11082 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +000011083

Georg Brandl3ee81df2008-05-17 18:14:43 +000011098 time so that opening a database previously created with the DB_DUP
11099 or DB_DUPSORT flag set will keep the proper behavior on subsequent
11100 opens. Specifically: dictionary assignment to a DB object will
11101 replace all values for a given key when the database allows
11102 duplicate values. DB users should use DB.put(k, v) when they want
11103 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +000011104

11110 characters with ASCII value less than 32. Also, it correctly quotes
11111 dots only if they occur on a single line, as opposed to the previous
11112 behavior of quoting dots if they are the second character of any
11113 line.
Georg Brandl4aef7272007-03-13 22:49:43 +000011114

11442
Georg Brandl3ee81df2008-05-17 18:14:43 +000011443- Unified naming convention for free lists and their limits. All free
11444 lists in Object/ are named ``free_list``, the counter ``numfree``
11445 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
11446 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +000011447
Georg Brandl3ee81df2008-05-17 18:14:43 +000011448- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
11449 to ``PyTuple_SetItem``, it can be used to populate a brand new
11450 frozenset; but it does not steal a reference to the added item.

11459
11460- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
11461 ``PyFloat_GetInfo()`` to the float API.
11462
Georg Brandl3ee81df2008-05-17 18:14:43 +000011463- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
11464 of w# format code incorrectly truncated the length to an int, even
11465 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
11466 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +000011467
Georg Brandl3ee81df2008-05-17 18:14:43 +000011468- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

11485
11486- Fix some leftovers from the conversion from int to Py_ssize_t
11487 (relevant to strings and sequences of more than 2**31 items).
11488
11489- Make _PyGILState_NoteThreadState() static, it was not used anywhere
11490 outside of pystate.c and should not be necessary.
11491
Georg Brandl3ee81df2008-05-17 18:14:43 +000011492- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
11493 absolute imports. In earlier versions they might have used relative
11494 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000011495
Georg Brandl3ee81df2008-05-17 18:14:43 +000011496- Added case insensitive comparison methods ``PyOS_stricmp(char*,
11497 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000011498
Georg Brandl3ee81df2008-05-17 18:14:43 +000011499- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +000011505- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
11506 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
11507 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
11508 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000011509

Georg Brandl3ee81df2008-05-17 18:14:43 +000011522- Removed the macfs module. It had been deprecated since Python 2.5.
11523 This lead to the deprecation of macostools.touched() as it relied
11524 solely on macfs and was a no-op under OS X.
