Martin Panter0d84ea72016-05-22 03:11:44 +0000898- Issue #15348: Stop the debugger engine (normally in a user process)
Terry Jan Reedya3ce2e52015-11-21 13:18:50 -0500899 before closing the debugger window (running in the IDLE process).
900 This prevents the RuntimeErrors that were being caught and ignored.
901
902- Issue #24455: Prevent IDLE from hanging when a) closing the shell while the
903 debugger is active (15347); b) closing the debugger with the [X] button
904 (15348); and c) activating the debugger when already active (24455).
905 The patch by Mark Roseman does this by making two changes.
906 1. Suspend and resume the gui.interaction method with the tcl vwait
907 mechanism intended for this purpose (instead of root.mainloop & .quit).
908 2. In gui.run, allow any existing interaction to terminate first.
909
910- Change 'The program' to 'Your program' in an IDLE 'kill program?' message
911 to make it clearer that the program referred to is the currently running
912 user program, not IDLE itself.

2374
2375- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
2376 and later systems as is currently done for Python 3.x installers.
2377 For 2.7.7 only, we will provide three installers:
2378 the legacy deprecated 10.3+ 32-bit-only format;
2379 the newer 10.5+ 32-bit-only format;
2380 and the unchanged 10.6+ 64-/32-bit format.
2381 Although binary installers will no longer be available from
2382 python.org as of 2.7.8, it will still be possible to build from
2383 source on 10.3.9 and 10.4 systems if necessary.
2384 See Mac/BuildScript/README.txt for more information.

2714 options like -fwrapv were overridden and thus not used, which could result
2715 in broken interpreters when building with clang.

3766 32-bit-only installer Pythons on systems with Xcode 4 (currently
3767 OS X 10.8, 10.7, and optionally 10.6).
3768 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
3769 * Since Xcode 4 removes ppc support, extension module builds now
3770 check for ppc compiler support and by default remove ppc and
3771 ppc64 archs when they are not available.
3772 * Extension module builds now revert to using system installed
3773 headers and libs (/usr and /System/Library) if the SDK used
3774 to build the interpreter is not installed or has moved.
3775 * Try to avoid building extension modules with deprecated
3776 and problematic Apple llvm-gcc compiler. If original compiler
3777 is not available, use clang instead by default.

4143 incorrect results with recent versions of Clang, as a result of the

4145 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deilyc47a4592012-02-11 20:40:24 +01004215 has left two versions of customize_compiler, the original in

Ned Deily0d0ea482012-02-10 12:59:06 +01004221- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
4222 Distutils-based packages with C extension modules may fail because
4223 Apple has removed gcc-4.2, the version used to build python.org
4224 64-bit/32-bit Pythons. If the user does not explicitly override
4225 the default C compiler by setting the CC environment variable,
4226 Distutils will now attempt to compile extension modules with clang
4227 if gcc-4.2 is required but not found. Also as a convenience, if
4228 the user does explicitly set CC, substitute its value as the default
4229 compiler in the Distutils LDSHARED configuration variable for OS X.
4230 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
4231 SDK, neither of which are available in Xcode 4. This change does not
4232 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07004482- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
4483 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
4484 interpreter process. This could cause failures in non-Distutils subprocesses
4485 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02004486 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07004487 deployment target only in the environment of each build subprocess. It is
4488 still possible to globally override the default by setting
4489 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
4490 greater or equal to the default value, the value with which the interpreter
4491 was built.

4521 the ticker doesn't have to wind down to zero from the old starting point
4522 before the new interval takes effect. And if the user increases the
4523 interval, it makes sure the new limit takes effect right away rather have an
4524 early task switch before recognizing the new interval.

5522 This prevents user-created self-referencing ordered dictionaries from
5523 becoming permanently uncollectable GC garbage. The downside is that
5524 removing __del__ means that the internal doubly-linked list has to wait for
5525 GC collection rather than freeing memory immediately when the refcnt drops

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00005984- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
5985 start byte and the continuation byte(s) are now considered invalid, instead
5986 of the number of bytes specified by the start byte.
5987 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
5988 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
5989 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

5999 objects. (1) The comparison could incorrectly return True in some cases
6000 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
6001 (2) The comparison raised an OverflowError for large integers, leading

6115 instead of two in a non-framework build.

Georg Brandlfee0f442010-05-22 21:26:21 +00006142- Issue #1533: Fix inconsistency in range function argument processing: any
6143 non-float non-integer argument is now converted to an integer (if possible)
6144 using its __int__ method. Previously, only small arguments were treated this
6145 way; larger arguments (those whose __int__ was outside the range of a C long)

Georg Brandlfee0f442010-05-22 21:26:21 +00006196- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
6197 operation raises multiple signals and more than one of those signals is
6198 trapped, the specification determines the order in which the signals should be
6199 handled. In many cases this order wasn't being followed, leading to the wrong

Georg Brandlfee0f442010-05-22 21:26:21 +00006344- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00006345 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
6346 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
6347 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

Benjamin Peterson5da7e7c2010-03-06 22:44:07 +00006366
6367Core and Builtins
6368-----------------
6369
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00006370- Issue #7301: Add environment variable $PYTHONWARNINGS.
6371
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00006372- Issue #8329: Don't return the same lists from select.select when no fds are
6373 changed.
6374
Georg Brandlfee0f442010-05-22 21:26:21 +00006375- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00006376 on 64-bit machines. The shift count for either left or right shift is
6377 permitted to be up to sys.maxsize.
6378
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00006379- Ensure that tokenization of identifiers is not affected by locale.
6380
Georg Brandlfee0f442010-05-22 21:26:21 +00006381- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00006382
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00006383- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
6384
Georg Brandlfee0f442010-05-22 21:26:21 +00006385- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
6386 with a non-empty format string. This is an effort to future-proof user
6387 code. If a derived class does not currently implement __format__ but later
6388 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00006389 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00006390 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00006391
Antoine Pitroua57df2c2010-03-31 21:32:15 +00006392- Issue #8268: Old-style classes (not just instances) now support weak
6393 references.
6394
Georg Brandlfee0f442010-05-22 21:26:21 +00006395- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
6396 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00006397

6401 arguments to a function correct.
6402
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00006403- Issue #8164: Don't allow lambda functions to have a docstring.
6404
Victor Stinner66644262010-03-10 22:30:19 +00006405- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00006406 (SIGINT). If an error occurs while importing the site module, the error is
6407 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00006408 module.
6409
Collin Winter001a3952010-03-18 21:54:01 +00006410- Code objects now support weak references.

R. David Murray661303f2010-04-13 20:57:40 +00006415- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
6416
Antoine Pitrouf9de5342010-04-05 21:35:07 +00006417- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00006418 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
6419 `ssl.OPENSSL_VERSION_NUMBER`.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00006421- Issue #8310: Allow dis to examine new style classes.
6422
Georg Brandlfee0f442010-05-22 21:26:21 +00006423- Issue #8257: The Decimal construct now accepts a float instance directly,
6424 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00006425
6426 >>> Decimal(1.1)
6427 Decimal('1.100000000000000088817841970012523233890533447265625')
6428
Raymond Hettinger34c35b22010-04-03 10:22:00 +00006429- collections.Counter() now supports a subtract() method.
6430
Georg Brandlfee0f442010-05-22 21:26:21 +00006431- The functools module now has a total_ordering() class decorator to simplify
6432 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00006433
Georg Brandlfee0f442010-05-22 21:26:21 +00006434- The functools module also adds cmp_to_key() as a tool to transition old-style
6435 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00006436
Georg Brandlfee0f442010-05-22 21:26:21 +00006437- Issue #8294: The Fraction constructor now accepts Decimal and float instances
6438 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00006439
Georg Brandlfee0f442010-05-22 21:26:21 +00006440- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
6441 InvalidOperation instead of returning False. (Comparisons involving a quiet
6442 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
6443 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00006444
Georg Brandlfee0f442010-05-22 21:26:21 +00006445- Issue #2531: Comparison operations between floats and Decimal instances now
6446 return a result based on the numeric values of the operands; previously they
6447 returned an arbitrary result based on the relative ordering of id(float) and
6448 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00006449
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00006450- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00006451 argument `-` which tells it to read files to compile from stdin. Each line is
6452 read on demand and the named file is compiled immediately. (Original patch by
6453 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00006454
Georg Brandlfee0f442010-05-22 21:26:21 +00006455- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
6456 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00006458- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
6459 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00006460 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00006461
Georg Brandlfee0f442010-05-22 21:26:21 +00006462- Comparisons using one of <, <=, >, >= between a complex instance and a
6463 Fractions instance now raise TypeError instead of returning True/False. This
6464 makes Fraction <=> complex comparisons consistent with int <=> complex, float
6465 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00006466

6475
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00006476- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00006477 didn't support chflags() (for example ZFS under FreeBSD). The error is now
6478 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00006479
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00006480- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
6481 deprecated.
6482
Georg Brandlfee0f442010-05-22 21:26:21 +00006483- Issue #7860: platform.uname now reports the correct 'machine' type when Python

6491 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00006492
Georg Brandlfee0f442010-05-22 21:26:21 +00006493- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
6494 when logging occurs.

Georg Brandlfee0f442010-05-22 21:26:21 +00006518 for ``TimedRotatingFileHandler`` by using the modification time of an existing
6519 log file to compute the next rollover time. If the log file does not exist,
6520 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00006521
Georg Brandlba83f822010-03-14 09:50:54 +00006522- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Mark Dickinson4846a8e2010-04-03 14:05:10 +00006561- Issue #8300: When passing a non-integer argument to struct.pack with any
6562 integer format code, struct.pack first attempts to convert the non-integer

6567 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
6568 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00006569 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
6570 inconsistent: __int__ was used for some integer codes but not for others, and
6571 the set of integer codes for which it was used differed between native packing
6572 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00006880 file position when calling `truncate()`. It would previously change the file
6881 position to the given argument, which goes against the tradition of

Martin Panterb362f752015-11-02 03:37:02 +00006886 implementation is significantly faster and can be wrapped in an
Georg Brandlba83f822010-03-14 09:50:54 +00006887 ``io.BufferedReader`` object for more speedups. It also solves an issue
6888 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

6977-----------------
6978
Georg Brandlba83f822010-03-14 09:50:54 +00006979- The ``__complex__()`` method is now looked up on the class of instances to
6980 make it consistent with other special methods.

6984
Mark Dickinson1b34d252010-01-01 17:27:30 +00006985- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00006986 DeprecationWarning when passed a float argument where an integer was expected.
6987 These functions and methods now raise TypeError instead. The majority of the
6988 effects of this change are in the extension modules, but some core functions
6989 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
6990 and many unicode/str methods.

7004 of integers: the result of a/b is now correctly rounded for ints a and b (at
7005 least on IEEE 754 platforms), and in particular does not depend on the
7006 internal representation of a long.

7014
Georg Brandlba83f822010-03-14 09:50:54 +00007015 These executables now work properly with the arch(1) command: ``arch -ppc
7016 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00007172- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
7173 decimal string that's guaranteed to round back to x under correct rounding
7174 (with round-half-to-even rounding mode). Previously it gave a string based on
7175 rounding x to 17 decimal digits. repr(x) for a complex number behaves
7176 similarly. On platforms where the correctly-rounded strtod and dtoa code is
7177 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00007178
Georg Brandlba83f822010-03-14 09:50:54 +00007179- Issue #7117: On almost all platforms: float-to-string and string-to-float
7180 conversions within Python are now correctly rounded. Places these conversions
7181 occur include: str for floats and complex numbers; the float and complex
7182 constructors; old-style and new-style numeric formatting; serialization and
7183 deserialization of floats and complex numbers using marshal, pickle and json;
7184 parsing of float and imaginary literals in Python code; Decimal-to-float
7185 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00007186
Georg Brandlba83f822010-03-14 09:50:54 +00007187 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
7188 providing correctly-rounded strtod and dtoa C functions. This code is
7189 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
7190 the C compiler. There may be a small number of platforms on which correct
7191 operation of this code cannot be guaranteed, so the code is not used: notably,
7192 this applies to platforms where the C double format is not IEEE 754 binary64,
7193 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
7194 and Python's configure script is unable to determine how to change the FPU
7195 precision. On these platforms conversions use the platform strtod and dtoa,
7196 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00007197
Georg Brandlba83f822010-03-14 09:50:54 +00007198- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
7199 uses the correctly-rounded string <-> float conversions described above (when
7200 available), and so produces correctly rounded results that will display nicely
7201 under the float repr. There are two related small changes: (1) round now
7202 accepts any class with an ``__index__()`` method for its second argument (but
7203 no longer accepts floats for the second argument), and (2) an excessively
7204 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
7205 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00007352- Issue #5920: For ``float.__format__()``, change the behavior with the empty
7353 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
7354 but with at least one decimal point and with a default precision
7355 of 12. Previously, the behavior the same but with a default precision of 6.
7356 This more closely matches ``str()``, and reduces surprises when adding
7357 alignment flags to the empty presentation type. This also affects the new
7358 complex.__format__ in the same way.

7555
Georg Brandlba83f822010-03-14 09:50:54 +00007556- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
7557 file objects with closefd=False. The file descriptor is still kept open but
7558 the file object behaves like a closed file. The ``FileIO`` object also got a
7559 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00007579- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00007582- On windows, ``os.chdir()`` given unicode was not working if
7583 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
7584 this code path is really executed because I cannot move to such directory on
7585 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00007587- Issue #4069: When ``set.remove(element)`` is used with a set element, the
7588 element is temporarily replaced with an equivalent frozenset. But the
7589 eventual KeyError would always report the empty ``frozenset()`` as the missing
7590 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00007610- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
7611 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
7612 step. This avoids problems with counting UTF-8 bytes that ignores the effect
7613 of using the replace error handler in PyUnicode_DecodeUTF8().
7614
Walter Dörwald726ba8e2009-05-06 14:32:35 +00007615- Issue #3739: The unicode-internal encoder now reports the number of characters

7617
Georg Brandlba83f822010-03-14 09:50:54 +00007618- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

7620 gives improved memory leak detection when running under Valgrind, while taking
7621 advantage of pymalloc at other times.

8888 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00008889 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
8890 the tests if DISPLAY is defined but can't be used.

Georg Brandlba83f822010-03-14 09:50:54 +00008895- Issue #5354: New test support function import_fresh_module() makes it easy to
8896 import both normal and optimised versions of modules. test_heapq and

8898 C and Python implementations in the stdlib can be adjusted to use it over
8899 time.

8908 should cause a test to be skipped are now done using import_module from test
8909 support, which does the conversion.

9011
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00009012- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
9013 PyString_FromFormat or PyErr_Format to display size_t values. The macro
9014 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
9015 ``printf`` function, whereas PyString_FromFormat has an independent
9016 implementation and uses "%zd" on all platforms for size_t values.
9017 This makes a difference on win64, where ``printf`` needs "%Id" to display
9018 64bit values.
9019
Benjamin Peterson97179b02008-09-09 20:55:01 +00009020- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

9024 object; previously an int would be returned for small values. the __long__
9025 method is allowed to return either an int or a long, but the behaviour of
9026 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00009028- Issue #3751: str.rpartition would perform a left-partition when called with

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00009035 was correctly parsed but parsing of subsequent arguments failed.
9036
Vinay Sajip35e3b032008-09-01 14:33:59 +00009037- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00009038 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
9039 mechanism. In the process, fix a bug where isinstance() and issubclass(),
9040 when given a tuple of classes as second argument, were looking up
9041 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
9042 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00009181What's New in Python 2.6 beta 3?
9182================================
9183
Barry Warsaw07a4a382008-08-21 01:15:08 +00009184*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00009185
9186Core and Builtins
9187-----------------
9188
Guido van Rossumf8402962008-08-20 15:01:50 +00009189- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
9190 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
9191 extensions do not automatically benefit from the class attribute
9192 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
9193 to their tp_flags field if they care. This is a backwards
9194 compatibility feature; in 3.0, all types will use the cache by
9195 default.
9196
Benjamin Petersonf647dc12008-08-20 01:27:30 +00009197- Keyword arguments can now follow starred arguments. (``f(a, *args,
9198 keyword=23)`` is now valid syntax.)
9199
Thomas Heller0ad5ae02008-08-19 19:25:04 +00009200- ctypes function pointers that are COM methods have a boolean True
9201 value again.
9202
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00009203- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
9204 by denying s# to parse objects that have a releasebuffer procedure,
9205 and introducing s*.
9206
Georg Brandl1e13ea92008-08-11 09:07:59 +00009207- Issue #3537: Fix an assertion failure when an empty but presized dict
9208 object was stored in the freelist.
9209
Mark Dickinsonb6467572008-08-04 21:30:09 +00009210- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
9211 ValueError consistently across platforms.
9212
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00009213- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
9214 (64bit Unix, for example), unichr() would truncate its argument and return
9215 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
9216
Neal Norwitze7d8be82008-07-31 17:17:14 +00009217- Apply security patches from Apple.
9218
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00009219- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
9220 PyErr_ExceptionMatches returns 0 when an exception occurs there.
9221
Antoine Pitrou92f82162008-07-25 22:22:08 +00009222- Issue #1819: function calls with several named parameters are now on
9223 average 35% faster (as measured by pybench).
9224
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00009225- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
9226 the python debugger steps into a class statement: the free variables (local
9227 variables defined in an outer scope) would be deleted from the outer scope.
9228
Gregory P. Smith0470bab2008-07-22 04:46:32 +00009229- Issue #2620: Overflow checking when allocating or reallocating memory
9230 was not always being done properly in some python types and extension
9231 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
9232 all been updated to perform better checks and places in the code that
9233 would previously leak memory on the error path when such an allocation
9234 failed have been fixed.
9235
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00009236Library
9237-------
9238
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00009239- Issue #3612: Added some missing basic types in ctypes.wintypes.
9240
Benjamin Petersone977ad42008-08-20 01:42:01 +00009241- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
9242 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
9243
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00009244- Issue #2234: distutils failed for some versions of the cygwin compiler. The
9245 version reported by these tools does not necessarily follow the python
9246 version numbering scheme, so the module is less strict when parsing it.
9247
Nick Coghlanf70385a2008-08-18 12:42:46 +00009248- Issue #2235: Added Py3k warnings for types which will become unhashable
9249 under the stricter __hash__ inheritance rules in 3.0. Several types
9250 which did not meet the rules for hash invariants and were already
9251 unhashable in 3.0 have now been explicitly flagged as unhashable in
9252 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
9253 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
9254
Brett Cannon88f801d2008-08-18 00:46:22 +00009255- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
9256 imported into the module but exposed as part of the module's API.
9257
Brett Cannon7b96f072008-08-18 00:41:11 +00009258- Remove an unneeded import of abc.ABCMeta from 'inspect'.
9259
Brett Cannon46225e72008-08-18 00:36:52 +00009260- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
9261
Brett Cannon25c9d6a2008-08-17 22:10:11 +00009262- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
9263
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00009264- Issue #3575: Incremental decoder's decode function now takes bytearray
9265 by using 's*' instead of 't#'.
9266
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00009267- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00009268 fails unicode conversion on 2nd parameter. (windows only)
9269
Georg Brandl222e2082010-08-01 22:27:39 +00009270- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00009271 in a redirect.
9272
Brett Cannonabe423e2008-08-16 21:47:07 +00009273- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00009274 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00009275
Martin Panter6a8163a2016-04-15 02:14:19 +00009276- Issue #2776: fixed small issue when handling a URL with double slash
Facundo Batistaeb90b782008-08-16 14:44:07 +00009277 after a 302 response in the case of not going through a proxy.
9278
Antoine Pitroub90a8be2008-08-15 21:03:21 +00009279- Issue #2676: in the email package, content-type parsing was hanging on
9280 pathological input because of quadratic or exponential behaviour of a
9281 regular expression.
9282
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00009283- Issue #3476: binary buffered reading through the new "io" library is now
9284 thread-safe.
9285
Brett Cannonbf3157b2008-08-14 05:00:03 +00009286- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
9287 since mimetools itself is deprecated. Because modules are cached, all
9288 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
9289
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00009290- Issue #3134: shutil referenced undefined WindowsError symbol.
9291
Robert Schuppenies14646332008-08-10 11:01:53 +00009292- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
9293 menu entries were not deleted.
9294
Brett Cannon83e81842008-08-09 23:30:55 +00009295- Copied the implementation of reduce() to _functools.reduce() to have a
9296 version that did not raise a DeprecationWarning under -3.
9297
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00009298- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
9299 a MemoryError rather than silently stop the iteration.
9300
Guido van Rossum59ce9012008-08-09 14:55:34 +00009301- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
9302 to _sre.compile() will now be rejected. This should not affect anybody
9303 since the re.compile() function never generates invalid re-bytecode.
9304
Skip Montanaroa032bf42008-08-08 22:52:51 +00009305- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
9306 upon first access it can be automatically initialized from the csv file if
9307 it wasn't initialized during instantiation.
9308
Brett Cannon3aa2a492008-08-06 22:28:09 +00009309- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
9310 the reload() built-in has been removed.
9311
Brett Cannon7e30b672008-08-04 21:52:25 +00009312- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00009313 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Brett Cannon7e30b672008-08-04 21:52:25 +00009319
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00009320- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
9321 raised an AttributeError.
9322
Benjamin Peterson01a24322008-07-28 23:35:27 +00009323- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00009324 asking for a specific length. This problem only affected files opened
9325 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00009326
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00009327- Issue #3449: Update decimal module to use most recent specification
9328 (v. 1.68) and tests (v. 2.58) from IBM.
9329
Georg Brandl222e2082010-08-01 22:27:39 +00009330- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00009331

9334
Georg Brandlf9efabb2008-07-23 15:16:45 +00009335- Deprecate the "ast" parser function aliases.
9336
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00009337- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
9338
9339- Issue #3303: Fix a crash in locale.strcoll() when calling it with
9340 invalid arguments.
9341
9342- Issue #3302: Fix several crashes when calling locale's gettext functions
9343 with None arguments.
9344
9345- Issue #3389: Allow resolving dotted names for handlers in logging
9346 configuration files.
9347
9348- Deprecate the sunaudio module for removal in Python 3.0.
9349
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00009350- Issue #3394: zipfile.writestr sets external attributes when passed a
9351 file name rather than a ZipInfo instance, so files are extracted with
9352 mode 0600 rather than 000 under Unix.
9353
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00009354- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
9355 argument in python 2.5, this broke code that subclassed Popen to include its
9356 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00009366- Issue #2235: the C API function PyObject_HashNotImplemented and its
9367 interaction with the tp_hash slot (added in 2.6b2) are now documented
9368
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00009369- Issue #643841: The language reference now provides more detailed
9370 coverage of the lookup process for special methods. The disclaimers
9371 regarding lack of coverage of new-style classes have also been
9372 removed, since the coverage is now fairly reasonable.

9381-----------------
9382
Georg Brandl3e483f62008-07-16 22:57:41 +00009383- Issue #3156: Fix inconsistent behavior of the bytearray type: all
9384 its methods now allow for items objects that can be converted to
9385 an integer using operator.index().
9386
Mark Dickinson64b7e502008-07-16 09:40:03 +00009387- Issue #3360: Fix incorrect parsing of '020000000000.0', which
9388 produced a ValueError instead of giving the correct float.
9389
Eric Smitha5fa5a22008-07-16 00:11:49 +00009390- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
9391 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
9392
Mark Dickinson7103aa42008-07-15 19:08:33 +00009393- Issue #3008: the float type has a new instance method 'float.hex'
9394 and a new class method 'float.fromhex' to convert floating-point
9395 numbers to and from hexadecimal strings, respectively.
9396
Nick Coghlan6d6bd442008-07-15 15:40:22 +00009397- Issue #2235: __hash__ is once again inherited by default. To allow
9398 collections.Hashable to remain meaningful in the presence of the
9399 default hash implementation (object.__hash__), it is now possible
9400 to explicit block inheritance of hash by setting __hash__=None at
9401 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
9402 level.
9403
Nick Coghlanb028f502008-07-13 14:52:36 +00009404- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
9405 the parent module cannot be found while performing an absolute import.
9406 This means that an incorrectly defined __package__ attribute will
9407 now only prevent relative imports in that module rather than causing
9408 all imports from that module to fail.
9409
Nick Coghlan14ff9942008-07-08 14:21:42 +00009410- Issue #2517: Allow unicode messages in Exceptions again by correctly
9411 bypassing the instance dictionary when looking up __unicode__ on
9412 new-style classes.

9420 another thread's dictionary.
9421
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00009422- Issue #3004: Minor change to slice.indices(): the start and stop
9423 arguments are now treated identically, making the behaviour easier
9424 to describe and understand. For example, slice(None, -10,
9425 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
9426 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
9427 10, -1).
9428
Georg Brandl278fc502008-07-19 12:46:12 +00009429- Issue #3219: Calling a function with repeated keyword arguments,

9877 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00009878 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00009879
9880 This is controlled by the configure argument ``--with-universal-archs``:
9881
9882 - ``--with-universal-archs=all``: install 4-way universal
9883
9884 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
9885
9886 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
9887
9888 This option should be used in combination with ``--enable-universalsdk=``.
9889
9890 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 +00009939- Issue #1631171: Re-implement the 'warnings' module in C (the
9940 original Python code has been kept as backup). This will allow for
9941 using the 'warning's machinery in such places as the parser where
9942 use of pure Python code is not possible. Both the ``showarning()``
9943 and ``formatwarning()`` gain an optional 'line' argument which is
9944 not called by default for backwards-compatibility reasons. Setting
9945 ``warnings.showwarning()`` to an implementation that lacks support
9946 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010001- Issue #2385: distutils.core.run_script() makes __file__ available,
10002 so the controlled environment will more closely mirror the typical
10003 script environment. This supports setup.py scripts that refer to
10004 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010009- Issue #2550: The approach used by client/server code for obtaining
10010 ports to listen on in network-oriented tests has been refined in an
10011 effort to facilitate running multiple instances of the entire
10012 regression test suite in parallel without issue.
10013 test_support.bind_port() has been fixed such that it will always
10014 return a unique port -- which wasn't always the case with the
10015 previous implementation, especially if socket options had been set
10016 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
10017 new implementation of bind_port() will actually raise an exception
10018 if it is passed an AF_INET/SOCK_STREAM socket with either the
10019 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
10020 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
10021 the socket it's been passed. This currently only applies to
10022 Windows. This option prevents any other sockets from binding to the
10023 host/port we've bound to, thus removing the possibility of the
10024 'non-deterministic' behaviour, as Microsoft puts it, that occurs
10025 when a second SOCK_STREAM socket binds and accepts to a host/port
10026 that's already been bound by another socket. The optional preferred
10027 port parameter to bind_port() has been removed. Under no
10028 circumstances should tests be hard coding ports!
10029
10030 test_support.find_unused_port() has also been introduced, which will
10031 pass a temporary socket object to bind_port() in order to obtain an
10032 unused port. The temporary socket object is then closed and
10033 deleted, and the port is returned. This method should only be used
10034 for obtaining an unused port in order to pass to an external program
10035 (i.e. the -accept [port] argument to openssl's s_server mode) or as
10036 a parameter to a server-oriented class that doesn't give you direct
10037 access to the underlying socket used.
10038
10039 Finally, test_support.HOST has been introduced, which should be used
10040 for the host argument of any relevant socket calls (i.e. bind and
10041 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +000010042
10043 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +000010044 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +000010045 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
10046 test_asynchat and test_socket_ssl.
10047
Georg Brandl3ee81df2008-05-17 18:14:43 +000010048 It is now possible for multiple instances of the regression test
10049 suite to run in parallel without issue.

10254 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +000010255 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
10256 files are used. On all linux systems the --with-system-ffi
10257 configure option defaults to "yes".

10317
Fred Drakea8ee94b2008-03-01 02:45:07 +000010318- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +000010319 644. The mode is now inherited from the py file.

Vinay Sajipb7edfc42008-04-02 21:10:23 +000010325- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +000010326 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +000010327
Eric Smitha73fbe72008-02-23 03:09:44 +000010328- Added the future_builtins module, which contains hex() and oct().
10329 These are the PEP 3127 version of these functions, designed to be
10330 compatible with the hex() and oct() builtins from Python 3.0. They
10331 differ slightly in their output formats from the existing, unchanged
10332 Python 2.6 builtins. The expected usage of the future_builtins
10333 module is:
10334 from future_builtins import hex, oct
10335
Martin Pantera850ef62016-07-28 01:11:04 +000010336- Issue #1600: Modified PyOS_ascii_formatd to use at most 2 digit
Eric Smith7ef40bf2008-02-20 23:34:22 +000010337 exponents for exponents with absolute value < 100. Follows C99
10338 standard. This is a change on Windows, which would use 3 digits.
10339 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
10340 so that any alterations it does to the resulting string will be
10341 available in stringlib/formatter.h (for float.__format__).
10342
Eric Smith5a3c1352008-02-19 13:21:56 +000010343- Implemented PEP 3101, Advanced String Formatting. This adds a new
10344 builtin format(); a format() method for str and unicode; a
10345 __format__() method to object, str, unicode, int, long, float, and
10346 datetime; the class string.Formatter; and the C API
10347 PyObject_Format().
10348
Georg Brandl3ee81df2008-05-17 18:14:43 +000010349- Fixed several potential crashes, all caused by specially crafted
10350 __del__ methods exploiting objects in temporarily inconsistent
10351 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +000010352
Vinay Sajipb7edfc42008-04-02 21:10:23 +000010353- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +000010354 prevent a possible crash: an Abstract Base Class would try to access
10355 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +000010356

10358 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +000010359
Georg Brandl3ee81df2008-05-17 18:14:43 +000010360- Clear all free lists during a gc.collect() of the highest generation
10361 in order to allow pymalloc to free more arenas. Python may give back
10362 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +000010363
Georg Brandl3ee81df2008-05-17 18:14:43 +000010364- Issue #2045: Fix an infinite recursion triggered when printing a
10365 subclass of collections.defaultdict, if its default_factory is set
10366 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +000010367
Christian Heimesf75dbef2008-02-08 00:11:31 +000010368- Fixed a minor memory leak in dictobject.c. The content of the free
10369 list was not freed on interpreter shutdown.
10370
Georg Brandl21e99f42010-03-07 15:23:59 +000010371- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +000010372 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +000010373
Georg Brandl3ee81df2008-05-17 18:14:43 +000010374- Patch #1953: Added ``sys._compact_freelists()`` and the C API
10375 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +000010376 to compact the internal free lists of pre-allocted ints and floats.
10377
Georg Brandl3ee81df2008-05-17 18:14:43 +000010378- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
10379 calls. Python expected the return type int but the fork familie
10380 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +000010381
Georg Brandl3ee81df2008-05-17 18:14:43 +000010382- Issue #1678380: Fix a bug that identifies 0j and -0j when they
10383 appear in the same code unit.

10392 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +000010393
Georg Brandl3ee81df2008-05-17 18:14:43 +000010394- Patch #1473257: generator objects gain a gi_code attribute. This is
10395 the same object as the func_code attribute of the function that
10396 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +000010397
Georg Brandl3ee81df2008-05-17 18:14:43 +000010398- Issue #1920: "while 0" statements were completely removed by the
10399 compiler, even in the presence of an "else" clause, which is
10400 supposed to be run when the condition is false. Now the compiler
10401 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +000010402
Guido van Rossumeead05f2008-01-24 18:21:02 +000010403- A few crashers fixed: weakref_in_del.py (issue #1377858);
10404 loosing_dict_ref.py (issue #1303614, test67.py);
10405 borrowed_ref_[34].py (not in tracker).
10406
Vinay Sajipd7cf32e2008-01-24 12:43:33 +000010407- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +000010408 suppressed while an extension is loaded by calling SetErrorMode in
10409 dynload_win.c. The error is still reported properly.
10410
Georg Brandl3ee81df2008-05-17 18:14:43 +000010411- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +000010412 several extension methods and modules do not work without unicode
10413 support.
10414
Georg Brandl26543b12008-01-21 18:36:51 +000010415- Issue #1882: when compiling code from a string, encoding cookies in the
10416 second line of code were not always recognized correctly.
10417
Georg Brandl14404b62008-01-19 19:27:05 +000010418- Issue #1679: "0x" was taken as a valid integer literal.
10419
Georg Brandl6caad7d2008-01-26 14:19:22 +000010420- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +000010421 added.
10422
Christian Heimesc94e2b52008-01-14 04:13:37 +000010423- sys.float_info / PyFloat_GetInfo: The floating point information
10424 object was converted from a dict to a specialized structseq object.
10425
Georg Brandl3ee81df2008-05-17 18:14:43 +000010426- Patch #1816: Added sys.flags structseq. It exposes the status of
10427 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +000010428
Georg Brandl3ee81df2008-05-17 18:14:43 +000010429- Objects/structseq.c: Implemented new structseq representation. The

10431 readable.
Christian Heimes9c201962008-01-14 03:33:52 +000010432
Georg Brandl3ee81df2008-05-17 18:14:43 +000010433- Patch #1700288: added a type attribute cache that caches method

10442 envvar and sys.dont_write_bytecode attribute. All these can be set
10443 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +000010444
Georg Brandl3ee81df2008-05-17 18:14:43 +000010445- Improve some exception messages when Windows fails to load an
10446 extension module. Now we get for example '%1 is not a valid Win32
10447 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +000010448

Christian Heimes0a8143f2007-12-18 23:22:54 +000010454- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +000010455 and INF. float("nan"), float("inf") and float("-inf") now work on
10456 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +000010457
Georg Brandl3ee81df2008-05-17 18:14:43 +000010458- Compiler now generates simpler and faster code for dictionary
10459 literals. The oparg for BUILD_MAP now indicates an estimated
10460 dictionary size. There is a new opcode, STORE_MAP, for adding
10461 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010490- Patch #1739468: Directories and zipfiles containing a __main__.py
10491 file can now be directly executed by passing their name to the
10492 interpreter. The directory/zipfile is automatically inserted as the
10493 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010495- Issue #1265: Fix a problem with sys.settrace, if the tracing
10496 function uses a generator expression when at the same time the
10497 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +000010498
Raymond Hettinger1760c8a2007-11-08 02:52:43 +000010499- sets and frozensets now have an isdisjoint() method.
10500
Raymond Hettinger3f8caa32007-10-24 01:28:33 +000010501- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +000010503- Fix warnings found by the new version of the Coverity checker.
10504
Georg Brandl21e99f42010-03-07 15:23:59 +000010505- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +000010506 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
10507 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +000010508
Georg Brandl3ee81df2008-05-17 18:14:43 +000010509- Issue #1686386: Tuple's tp_repr did not take into account the
10510 possibility of having a self-referential tuple, which is possible
10511 from C code. Nor did object's tp_str consider that a type's tp_str
10512 could do something that could lead to an inifinite recursion.
10513 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
10514 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +000010515
Georg Brandl3ee81df2008-05-17 18:14:43 +000010516- Issue #1164: It was possible to trigger deadlock when using the
10517 'print' statement to write to a file since the GIL was not released
10518 as needed. Now PyObject_Print() does the right thing along with
10519 various tp_print implementations of the built-in types and those in
10520 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +000010521
Georg Brandl3ee81df2008-05-17 18:14:43 +000010522- Issue #1147: Exceptions were directly allowing string exceptions in
10523 their throw() method even though string exceptions no longer
10524 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +000010525
Georg Brandl3ee81df2008-05-17 18:14:43 +000010526- Issue #1096: Prevent a segfault from getting the repr of a very
10527 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +000010528
Brett Cannon1e534b52007-09-07 04:18:30 +000010529- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +000010530 PyObject_Call() never calling back out to Python code to trigger
10531 recursion depth updates/checks. Required the creation of a static
10532 RuntimeError instance in case normalizing an exception put the
10533 recursion check value past its limit. Fixes crashers
10534 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +000010535

Neal Norwitz0ac60192007-05-27 04:08:54 +000010549- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +000010550 __*__ attributes. (Some already existed, e.g., __doc__ and
10551 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +000010552
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +000010553- Add -3 option to the interpreter to warn about features that are
10554 deprecated and will be changed/removed in Python 3.0.
10555
Georg Brandl2134e752007-05-21 20:34:16 +000010556- Patch #1686487: you can now pass any mapping after '**' in function
10557 calls.
10558
Collin Winter62903052007-05-18 23:11:24 +000010559- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +000010560 "except E as target:". This is to provide forwards compatibility
10561 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +000010562
Brett Cannon229cee22007-05-05 01:34:02 +000010563- Deprecate BaseException.message as per PEP 352.
10564
Georg Brandl3ee81df2008-05-17 18:14:43 +000010565- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +000010566 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +000010567
Vinay Sajip8549ce32007-05-06 17:53:37 +000010568- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +000010569 setting a plain string, ie don't expand to single letter identifiers.
10570
Serhiy Storchaka16870742015-08-09 13:07:06 +030010571- Request #1191699: Slices can now be pickled.

Serhiy Storchaka16870742015-08-09 13:07:06 +030010573- Request #1193128: str.translate() now allows a None argument for
Raymond Hettinger4db5fe92007-04-12 04:10:00 +000010574 translations that only remove characters without re-mapping the
10575 remaining characters.
10576
Georg Brandl5cb76c12007-03-21 09:00:39 +000010577- Patch #1682205: a TypeError while unpacking an iterable is no longer
10578 masked by a generic one with the message "unpack non-sequence".
10579
Neal Norwitzaa754b72007-03-21 06:39:48 +000010580- Remove unused file Python/fmod.c.
10581
Guido van Rossum143b5642007-03-23 04:58:42 +000010582- Bug #1683368: The object.__init__() and object.__new__() methods are
10583 now stricter in rejecting excess arguments. The only time when
10584 either allows excess arguments is when it is not overridden and the
10585 other one is. For backwards compatibility, when both are
10586 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +000010587 warning later). Also, type.__init__() insists on the same signature
10588 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +000010589
Georg Brandl3ee81df2008-05-17 18:14:43 +000010590- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
10591 object to complex using its __complex__() method before falling back
10592 to the __float__() method. Therefore, the functions in the cmath
10593 module now can operate on objects that define a __complex__()
10594 method.
Georg Brandl2b869942007-03-17 16:08:45 +000010595
Georg Brandl3ee81df2008-05-17 18:14:43 +000010596- Patch #1623563: allow __class__ assignment for classes with
10597 __slots__. The old and the new class are still required to have the
10598 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +000010599

10604 ``object.__reduce_ex__()`` is called with an object that is faking
10605 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +000010606
Martin Panter6a8163a2016-04-15 02:14:19 +000010607- Patch #1680015: Don't modify __slots__ tuple if it contains a
Georg Brandl3ee81df2008-05-17 18:14:43 +000010608 unicode name.
Žiga Seilnacht71436f02007-03-14 12:24:09 +000010609
Georg Brandl5240d742007-03-13 20:46:32 +000010610- Patch #1444529: the builtin compile() now accepts keyword arguments.
10611
Georg Brandl7b9c5552007-03-12 14:30:05 +000010612- Bug #1678647: write a newline after printing an exception in any
10613 case, even when converting the value to a string failed.
10614
Georg Brandl871f1bc2007-03-12 13:17:36 +000010615- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +000010616 its argument, if it exists. If not, it will work like before. This
10617 allows customizing the output of dir() in the presence of a
10618 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +000010619

Georg Brandl3ee81df2008-05-17 18:14:43 +000010626- Patch #1491866: change the complex() constructor to allow
10627 parthensized forms. This means complex(repr(x)) now works instead of
10628 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +000010629
Georg Brandlaa2321b2007-03-07 00:40:28 +000010630- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +000010631 makes the filenames the warning module prints much more sensible
10632 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +000010633
Georg Brandl49aafc92007-03-07 00:34:46 +000010634- Variant of patch #697613: don't exit the interpreter on a SystemExit
10635 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +000010636 variable is given, but break into the interactive interpreter just
10637 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010642- Bug #1674503: close the file opened by execfile() in an error
10643 condition.
Georg Brandl098cd692007-03-06 12:17:50 +000010644
Georg Brandl0fca97a2007-03-05 22:28:08 +000010645- Patch #1674228: when assigning a slice (old-style), check for the

10647
Georg Brandl3ee81df2008-05-17 18:14:43 +000010648- When printing an unraisable error, don't print exceptions. before
10649 the name. This duplicates the behavior whening normally printing
10650 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +000011200- Patch #1530482: add pydoc.render_doc() which returns the
11201 documentation for a thing instead of paging it to stdout, which

11215
Georg Brandl92a6bae2007-03-13 17:43:32 +000011216- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +000011217 are set for invalid interpolation sequences that would lead to
11218 errors on reading back those values.

Georg Brandl3ee81df2008-05-17 18:14:43 +000011273- unittest now verifies more of its assumptions. In particular,
11274 TestCase and TestSuite subclasses (not instances) are no longer
11275 accepted in TestSuite.addTest(). This should cause no
11276 incompatibility since it never made sense with ordinary subclasses
11277 -- the failure just occurred later, with a more cumbersome
11278 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +000011559 that the SMTP.starttls() caller no longer needs to call ehlo()
11560 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +000011561 does not claim to support starttls. Adds the

Gregory P. Smithec10a4a2007-11-05 02:32:26 +000011660- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +000011661 time so that opening a database previously created with the DB_DUP
11662 or DB_DUPSORT flag set will keep the proper behavior on subsequent
11663 opens. Specifically: dictionary assignment to a DB object will
11664 replace all values for a given key when the database allows
11665 duplicate values. DB users should use DB.put(k, v) when they want
11666 to store duplicates; not DB[k] = v.

12027 of w# format code incorrectly truncated the length to an int, even
12028 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
12029 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +000012059- Added case insensitive comparison methods ``PyOS_stricmp(char*,
12060 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
