Ned Deily18fae3f2013-01-31 01:24:55 -08001740- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1741 In particular, fix extension module build failures when trying to use
1742 32-bit-only installer Pythons on systems with Xcode 4 (currently
1743 OS X 10.8, 10.7, and optionally 10.6).
1744 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1745 * Since Xcode 4 removes ppc support, extension module builds now
1746 check for ppc compiler support and by default remove ppc and
1747 ppc64 archs when they are not available.
1748 * Extension module builds now revert to using system installed
1749 headers and libs (/usr and /System/Library) if the SDK used
1750 to build the interpreter is not installed or has moved.
1751 * Try to avoid building extension modules with deprecated
1752 and problematic Apple llvm-gcc compiler. If original compiler
1753 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01002104- Issue #12973: Fix overflow checks that invoked undefined behaviour in
2105 int.__pow__. These overflow checks were causing int.__pow__ to produce
2106 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01002107 compiler optimizing the check away. Also fix similar overflow checks
2108 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

2121 cleared by the garbage collector. This fixes a segfault when an instance
2122 and its type get caught in a reference cycle, and the instance's
2123 deallocator calls one of the methods on the type (e.g. when subclassing
2124 IOBase). Diagnosis and patch by Davide Rizzo.

Florent Xiclunac2279652012-02-12 14:49:03 +01002177- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002178 has left two versions of customize_compiler, the original in
2179 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01002184- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2185 Distutils-based packages with C extension modules may fail because
2186 Apple has removed gcc-4.2, the version used to build python.org
2187 64-bit/32-bit Pythons. If the user does not explicitly override
2188 the default C compiler by setting the CC environment variable,
2189 Distutils will now attempt to compile extension modules with clang
2190 if gcc-4.2 is required but not found. Also as a convenience, if
2191 the user does explicitly set CC, substitute its value as the default
2192 compiler in the Distutils LDSHARED configuration variable for OS X.
2193 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2194 SDK, neither of which are available in Xcode 4. This change does not
2195 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002445- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2446 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2447 interpreter process. This could cause failures in non-Distutils subprocesses
2448 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002449 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002450 deployment target only in the environment of each build subprocess. It is
2451 still possible to globally override the default by setting
2452 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2453 greater or equal to the default value, the value with which the interpreter
2454 was built.

Barry Warsawc5643282011-07-19 17:06:30 -04002482- sys.setcheckinterval() now updates the current ticker count as well as
2483 updating the check interval, so if the user decreases the check interval,
2484 the ticker doesn't have to wind down to zero from the old starting point
2485 before the new interval takes effect. And if the user increases the
2486 interval, it makes sure the new limit takes effect right away rather have an
2487 early task switch before recognizing the new interval.

3468 This prevents user-created self-referencing ordered dictionaries from
3469 becoming permanently uncollectable GC garbage. The downside is that

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003930- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3931 start byte and the continuation byte(s) are now considered invalid, instead
3932 of the number of bytes specified by the start byte.
3933 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3934 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3935 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

3945 objects. (1) The comparison could incorrectly return True in some cases
3946 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3947 (2) The comparison raised an OverflowError for large integers, leading

4089 non-float non-integer argument is now converted to an integer (if possible)
4090 using its __int__ method. Previously, only small arguments were treated this
4091 way; larger arguments (those whose __int__ was outside the range of a C long)

Georg Brandlfee0f442010-05-22 21:26:21 +00004142- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4143 operation raises multiple signals and more than one of those signals is
4144 trapped, the specification determines the order in which the signals should be
4145 handled. In many cases this order wasn't being followed, leading to the wrong

Georg Brandlfee0f442010-05-22 21:26:21 +00004290- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00004291 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
4292 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
4293 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

4313Core and Builtins
4314-----------------
4315
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004316- Issue #7301: Add environment variable $PYTHONWARNINGS.
4317
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004318- Issue #8329: Don't return the same lists from select.select when no fds are
4319 changed.
4320
Georg Brandlfee0f442010-05-22 21:26:21 +00004321- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004322 on 64-bit machines. The shift count for either left or right shift is
4323 permitted to be up to sys.maxsize.
4324
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004325- Ensure that tokenization of identifiers is not affected by locale.
4326
Georg Brandlfee0f442010-05-22 21:26:21 +00004327- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00004328
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00004329- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
4330
Georg Brandlfee0f442010-05-22 21:26:21 +00004331- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4332 with a non-empty format string. This is an effort to future-proof user
4333 code. If a derived class does not currently implement __format__ but later
4334 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004335 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004336 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004337
Antoine Pitroua57df2c2010-03-31 21:32:15 +00004338- Issue #8268: Old-style classes (not just instances) now support weak
4339 references.
4340
Georg Brandlfee0f442010-05-22 21:26:21 +00004341- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
4342 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00004343

Benjamin Peterson96545892010-03-21 20:21:00 +00004346- Issue #6474: Make error message from passing an inadequate number of keyword
4347 arguments to a function correct.
4348
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00004349- Issue #8164: Don't allow lambda functions to have a docstring.
4350
Victor Stinner66644262010-03-10 22:30:19 +00004351- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00004352 (SIGINT). If an error occurs while importing the site module, the error is
4353 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00004354 module.

4362
Antoine Pitrouf9de5342010-04-05 21:35:07 +00004363- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00004364 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
4365 `ssl.OPENSSL_VERSION_NUMBER`.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00004367- Issue #8310: Allow dis to examine new style classes.
4368
Georg Brandlfee0f442010-05-22 21:26:21 +00004369- Issue #8257: The Decimal construct now accepts a float instance directly,
4370 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004371
4372 >>> Decimal(1.1)
4373 Decimal('1.100000000000000088817841970012523233890533447265625')
4374
Raymond Hettinger34c35b22010-04-03 10:22:00 +00004375- collections.Counter() now supports a subtract() method.
4376
Georg Brandlfee0f442010-05-22 21:26:21 +00004377- The functools module now has a total_ordering() class decorator to simplify
4378 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00004379
Georg Brandlfee0f442010-05-22 21:26:21 +00004380- The functools module also adds cmp_to_key() as a tool to transition old-style
4381 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00004382
Georg Brandlfee0f442010-05-22 21:26:21 +00004383- Issue #8294: The Fraction constructor now accepts Decimal and float instances
4384 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00004385
Georg Brandlfee0f442010-05-22 21:26:21 +00004386- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4387 InvalidOperation instead of returning False. (Comparisons involving a quiet
4388 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4389 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004390
Georg Brandlfee0f442010-05-22 21:26:21 +00004391- Issue #2531: Comparison operations between floats and Decimal instances now
4392 return a result based on the numeric values of the operands; previously they
4393 returned an arbitrary result based on the relative ordering of id(float) and
4394 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004395
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004396- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004397 argument `-` which tells it to read files to compile from stdin. Each line is
4398 read on demand and the named file is compiled immediately. (Original patch by
4399 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004400
Georg Brandlfee0f442010-05-22 21:26:21 +00004401- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
4402 function like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +00004403
Florent Xicluna58b65662010-03-30 16:29:03 +00004404- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4405 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004406 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00004407
Georg Brandlfee0f442010-05-22 21:26:21 +00004408- Comparisons using one of <, <=, >, >= between a complex instance and a
4409 Fractions instance now raise TypeError instead of returning True/False. This
4410 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4411 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00004412
Michael Foorde6410c52010-03-29 20:04:23 +00004413- Addition of ``WeakSet`` to the ``weakref`` module.

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004422- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00004423 didn't support chflags() (for example ZFS under FreeBSD). The error is now
4424 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004425
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00004426- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
4427 deprecated.
4428
Georg Brandlfee0f442010-05-22 21:26:21 +00004429- Issue #7860: platform.uname now reports the correct 'machine' type when Python
4430 is running in WOW64 mode on 64 bit Windows.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00004466- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00004467 for ``TimedRotatingFileHandler`` by using the modification time of an existing
4468 log file to compute the next rollover time. If the log file does not exist,
4469 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00004470

Georg Brandlba83f822010-03-14 09:50:54 +00004479- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
4480 a base64 transfer-encoded payload *after* decoding it; it no longer does.
4481 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +00004510- Issue #8300: When passing a non-integer argument to struct.pack with any
4511 integer format code, struct.pack first attempts to convert the non-integer
4512 using its __index__ method. If that method is non-existent or raises
4513 TypeError it goes on to try the __int__ method, as described below.
4514
Georg Brandlba83f822010-03-14 09:50:54 +00004515- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4516 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4517 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004518 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4519 inconsistent: __int__ was used for some integer codes but not for others, and
4520 the set of integer codes for which it was used differed between native packing

4753 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00004754 library would return a bogus result; on Solaris, it was possible to crash the

Georg Brandlba83f822010-03-14 09:50:54 +00004773- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4774 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4775 returning NULL. The macro now returns a statically allocated empty string
4776 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00004829 file position when calling `truncate()`. It would previously change the file
4830 position to the given argument, which goes against the tradition of

4834 class used to represent files stored inside an archive. The new
4835 implementation is significantly faster and can be wrapped in a
4836 ``io.BufferedReader`` object for more speedups. It also solves an issue
4837 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

4850 encoded string for them. This ensures that the upload and register commands
4851 send the correct values to PyPI without any error.

4926-----------------
4927
Georg Brandlba83f822010-03-14 09:50:54 +00004928- The ``__complex__()`` method is now looked up on the class of instances to
4929 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004931- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
4932 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
4933
Mark Dickinson1b34d252010-01-01 17:27:30 +00004934- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004935 DeprecationWarning when passed a float argument where an integer was expected.
4936 These functions and methods now raise TypeError instead. The majority of the
4937 effects of this change are in the extension modules, but some core functions
4938 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4939 and many unicode/str methods.

4953 of integers: the result of a/b is now correctly rounded for ints a and b (at
4954 least on IEEE 754 platforms), and in particular does not depend on the
4955 internal representation of a long.

4963
Georg Brandlba83f822010-03-14 09:50:54 +00004964 These executables now work properly with the arch(1) command: ``arch -ppc
4965 python`` will start a universal binary version of python in PPC mode (unlike

5105 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005106
Georg Brandlba83f822010-03-14 09:50:54 +00005107- Remove switch from "%f" formatting to "%g" formatting for floats larger than
5108 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00005109

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00005120
Georg Brandlba83f822010-03-14 09:50:54 +00005121- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5122 decimal string that's guaranteed to round back to x under correct rounding
5123 (with round-half-to-even rounding mode). Previously it gave a string based on
5124 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5125 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5126 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005127
Georg Brandlba83f822010-03-14 09:50:54 +00005128- Issue #7117: On almost all platforms: float-to-string and string-to-float
5129 conversions within Python are now correctly rounded. Places these conversions
5130 occur include: str for floats and complex numbers; the float and complex
5131 constructors; old-style and new-style numeric formatting; serialization and
5132 deserialization of floats and complex numbers using marshal, pickle and json;
5133 parsing of float and imaginary literals in Python code; Decimal-to-float
5134 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005135
Georg Brandlba83f822010-03-14 09:50:54 +00005136 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5137 providing correctly-rounded strtod and dtoa C functions. This code is
5138 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5139 the C compiler. There may be a small number of platforms on which correct
5140 operation of this code cannot be guaranteed, so the code is not used: notably,
5141 this applies to platforms where the C double format is not IEEE 754 binary64,
5142 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5143 and Python's configure script is unable to determine how to change the FPU
5144 precision. On these platforms conversions use the platform strtod and dtoa,
5145 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005146
Georg Brandlba83f822010-03-14 09:50:54 +00005147- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5148 uses the correctly-rounded string <-> float conversions described above (when
5149 available), and so produces correctly rounded results that will display nicely
5150 under the float repr. There are two related small changes: (1) round now
5151 accepts any class with an ``__index__()`` method for its second argument (but
5152 no longer accepts floats for the second argument), and (2) an excessively
5153 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5154 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005301- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5302 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5303 but with at least one decimal point and with a default precision
5304 of 12. Previously, the behavior the same but with a default precision of 6.
5305 This more closely matches ``str()``, and reduces surprises when adding
5306 alignment flags to the empty presentation type. This also affects the new
5307 complex.__format__ in the same way.

5504
Georg Brandlba83f822010-03-14 09:50:54 +00005505- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5506 file objects with closefd=False. The file descriptor is still kept open but
5507 the file object behaves like a closed file. The ``FileIO`` object also got a
5508 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005528- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00005531- On windows, ``os.chdir()`` given unicode was not working if
5532 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5533 this code path is really executed because I cannot move to such directory on
5534 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00005536- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5537 element is temporarily replaced with an equivalent frozenset. But the
5538 eventual KeyError would always report the empty ``frozenset()`` as the missing
5539 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00005559- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5560 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5561 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5562 of using the replace error handler in PyUnicode_DecodeUTF8().
5563
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005564- Issue #3739: The unicode-internal encoder now reports the number of characters

5566
Georg Brandlba83f822010-03-14 09:50:54 +00005567- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
5568 allocator will be automatically disabled when running under Valgrind. This
5569 gives improved memory leak detection when running under Valgrind, while taking
5570 advantage of pymalloc at other times.

6816 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00006817 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
6818 the tests if DISPLAY is defined but can't be used.

6826 C and Python implementations in the stdlib can be adjusted to use it over
6827 time.

6939
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006940- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6941 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6942 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6943 ``printf`` function, whereas PyString_FromFormat has an independent
6944 implementation and uses "%zd" on all platforms for size_t values.
6945 This makes a difference on win64, where ``printf`` needs "%Id" to display
6946 64bit values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006963 was correctly parsed but parsing of subsequent arguments failed.
6964
Vinay Sajip35e3b032008-09-01 14:33:59 +00006965- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006966 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6967 mechanism. In the process, fix a bug where isinstance() and issubclass(),

6969 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6970 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007109What's New in Python 2.6 beta 3?
7110================================
7111
Barry Warsaw07a4a382008-08-21 01:15:08 +00007112*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007113
7114Core and Builtins
7115-----------------
7116
Guido van Rossumf8402962008-08-20 15:01:50 +00007117- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7118 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7119 extensions do not automatically benefit from the class attribute
7120 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7121 to their tp_flags field if they care. This is a backwards
7122 compatibility feature; in 3.0, all types will use the cache by
7123 default.
7124
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007125- Keyword arguments can now follow starred arguments. (``f(a, *args,
7126 keyword=23)`` is now valid syntax.)
7127
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007128- ctypes function pointers that are COM methods have a boolean True
7129 value again.
7130
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007131- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7132 by denying s# to parse objects that have a releasebuffer procedure,
7133 and introducing s*.
7134
Georg Brandl1e13ea92008-08-11 09:07:59 +00007135- Issue #3537: Fix an assertion failure when an empty but presized dict
7136 object was stored in the freelist.
7137
Mark Dickinsonb6467572008-08-04 21:30:09 +00007138- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7139 ValueError consistently across platforms.
7140
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007141- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7142 (64bit Unix, for example), unichr() would truncate its argument and return
7143 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7144
Neal Norwitze7d8be82008-07-31 17:17:14 +00007145- Apply security patches from Apple.
7146
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007147- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7148 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7149
Antoine Pitrou92f82162008-07-25 22:22:08 +00007150- Issue #1819: function calls with several named parameters are now on
7151 average 35% faster (as measured by pybench).
7152
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007153- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7154 the python debugger steps into a class statement: the free variables (local
7155 variables defined in an outer scope) would be deleted from the outer scope.
7156
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007157- Issue #2620: Overflow checking when allocating or reallocating memory
7158 was not always being done properly in some python types and extension
7159 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7160 all been updated to perform better checks and places in the code that
7161 would previously leak memory on the error path when such an allocation
7162 failed have been fixed.
7163
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007164Library
7165-------
7166
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007167- Issue #3612: Added some missing basic types in ctypes.wintypes.
7168
Benjamin Petersone977ad42008-08-20 01:42:01 +00007169- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7170 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7171
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007172- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7173 version reported by these tools does not necessarily follow the python
7174 version numbering scheme, so the module is less strict when parsing it.
7175
Nick Coghlanf70385a2008-08-18 12:42:46 +00007176- Issue #2235: Added Py3k warnings for types which will become unhashable
7177 under the stricter __hash__ inheritance rules in 3.0. Several types
7178 which did not meet the rules for hash invariants and were already
7179 unhashable in 3.0 have now been explicitly flagged as unhashable in
7180 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7181 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7182
Brett Cannon88f801d2008-08-18 00:46:22 +00007183- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7184 imported into the module but exposed as part of the module's API.
7185
Brett Cannon7b96f072008-08-18 00:41:11 +00007186- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7187
Brett Cannon46225e72008-08-18 00:36:52 +00007188- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
7189
Brett Cannon25c9d6a2008-08-17 22:10:11 +00007190- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7191
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007192- Issue #3575: Incremental decoder's decode function now takes bytearray
7193 by using 's*' instead of 't#'.
7194
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007195- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007196 fails unicode conversion on 2nd parameter. (windows only)
7197
Georg Brandl222e2082010-08-01 22:27:39 +00007198- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007199 in a redirect.
7200
Brett Cannonabe423e2008-08-16 21:47:07 +00007201- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007202 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007203
Facundo Batistaeb90b782008-08-16 14:44:07 +00007204- Issue #2776: fixed small issue when handling an URL with double slash
7205 after a 302 response in the case of not going through a proxy.
7206
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007207- Issue #2676: in the email package, content-type parsing was hanging on
7208 pathological input because of quadratic or exponential behaviour of a
7209 regular expression.
7210
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007211- Issue #3476: binary buffered reading through the new "io" library is now
7212 thread-safe.
7213
Brett Cannonbf3157b2008-08-14 05:00:03 +00007214- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7215 since mimetools itself is deprecated. Because modules are cached, all
7216 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7217
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007218- Issue #3134: shutil referenced undefined WindowsError symbol.
7219
Robert Schuppenies14646332008-08-10 11:01:53 +00007220- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7221 menu entries were not deleted.
7222
Brett Cannon83e81842008-08-09 23:30:55 +00007223- Copied the implementation of reduce() to _functools.reduce() to have a
7224 version that did not raise a DeprecationWarning under -3.
7225
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007226- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7227 a MemoryError rather than silently stop the iteration.
7228
Guido van Rossum59ce9012008-08-09 14:55:34 +00007229- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7230 to _sre.compile() will now be rejected. This should not affect anybody
7231 since the re.compile() function never generates invalid re-bytecode.
7232
Skip Montanaroa032bf42008-08-08 22:52:51 +00007233- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7234 upon first access it can be automatically initialized from the csv file if
7235 it wasn't initialized during instantiation.
7236
Brett Cannon3aa2a492008-08-06 22:28:09 +00007237- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7238 the reload() built-in has been removed.
7239
Brett Cannon7e30b672008-08-04 21:52:25 +00007240- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007241 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00007242 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
7243 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
7244 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
7245 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
7246 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00007247
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00007248- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
7249 raised an AttributeError.
7250
Benjamin Peterson01a24322008-07-28 23:35:27 +00007251- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00007252 asking for a specific length. This problem only affected files opened
7253 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007254
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00007255- Issue #3449: Update decimal module to use most recent specification
7256 (v. 1.68) and tests (v. 2.58) from IBM.
7257
Georg Brandl222e2082010-08-01 22:27:39 +00007258- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00007259

Raymond Hettinger8c664e82008-07-25 18:43:33 +00007261 on a closed shelf.
7262
Georg Brandlf9efabb2008-07-23 15:16:45 +00007263- Deprecate the "ast" parser function aliases.
7264
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007265- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
7266
7267- Issue #3303: Fix a crash in locale.strcoll() when calling it with
7268 invalid arguments.
7269
7270- Issue #3302: Fix several crashes when calling locale's gettext functions
7271 with None arguments.
7272
7273- Issue #3389: Allow resolving dotted names for handlers in logging
7274 configuration files.
7275
7276- Deprecate the sunaudio module for removal in Python 3.0.
7277
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00007278- Issue #3394: zipfile.writestr sets external attributes when passed a
7279 file name rather than a ZipInfo instance, so files are extracted with
7280 mode 0600 rather than 000 under Unix.
7281
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007282- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7283 argument in python 2.5, this broke code that subclassed Popen to include its
7284 own poll method. Fixed my moving _deadstate to an _internal_poll method.

7292-------------
7293
Nick Coghlan6e8fef02008-08-18 13:14:22 +00007294- Issue #2235: the C API function PyObject_HashNotImplemented and its
7295 interaction with the tp_hash slot (added in 2.6b2) are now documented
7296
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007297- Issue #643841: The language reference now provides more detailed
7298 coverage of the lookup process for special methods. The disclaimers
7299 regarding lack of coverage of new-style classes have also been
7300 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00007303What's New in Python 2.6 beta 2?
7304================================
7305
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007306*Release date: 17-Jul-2008*
7307
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007308Core and Builtins
7309-----------------
7310
Georg Brandl3e483f62008-07-16 22:57:41 +00007311- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7312 its methods now allow for items objects that can be converted to
7313 an integer using operator.index().
7314
Mark Dickinson64b7e502008-07-16 09:40:03 +00007315- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7316 produced a ValueError instead of giving the correct float.
7317
Eric Smitha5fa5a22008-07-16 00:11:49 +00007318- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7319 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7320
Mark Dickinson7103aa42008-07-15 19:08:33 +00007321- Issue #3008: the float type has a new instance method 'float.hex'
7322 and a new class method 'float.fromhex' to convert floating-point
7323 numbers to and from hexadecimal strings, respectively.
7324
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007325- Issue #2235: __hash__ is once again inherited by default. To allow
7326 collections.Hashable to remain meaningful in the presence of the
7327 default hash implementation (object.__hash__), it is now possible
7328 to explicit block inheritance of hash by setting __hash__=None at
7329 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7330 level.
7331
Nick Coghlanb028f502008-07-13 14:52:36 +00007332- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7333 the parent module cannot be found while performing an absolute import.
7334 This means that an incorrectly defined __package__ attribute will
7335 now only prevent relative imports in that module rather than causing
7336 all imports from that module to fail.
7337
Nick Coghlan14ff9942008-07-08 14:21:42 +00007338- Issue #2517: Allow unicode messages in Exceptions again by correctly
7339 bypassing the instance dictionary when looking up __unicode__ on
7340 new-style classes.
7341
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007342- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7343 set to a custom object whose write() method happens to install
7344 another file in sys.stdout.
7345
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007346- Issue #3088: Corrected a race condition in classes derived from
7347 threading.local: the first member set by a thread could be saved in
7348 another thread's dictionary.
7349
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007350- Issue #3004: Minor change to slice.indices(): the start and stop
7351 arguments are now treated identically, making the behaviour easier
7352 to describe and understand. For example, slice(None, -10,
7353 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7354 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7355 10, -1).
7356
Georg Brandl278fc502008-07-19 12:46:12 +00007357- Issue #3219: Calling a function with repeated keyword arguments,
7358 f(a=2, a=23), would not cause a syntax error. This was a regression
7359 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007360
Georg Brandl278fc502008-07-19 12:46:12 +00007361- Issue #2862: Make int and float freelist management consistent with
7362 other freelists. Changes their CompactFreeList apis into
7363 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00007364

7367
Thomas Heller57adf222008-08-14 19:10:48 +00007368- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
7369 api functions without holding the GIL, which could lead to a fatal
7370 error when they failed.
7371
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007372- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00007380- Issue #3125: Remove copy_reg in multiprocessing and replace it with
7381 ForkingPickler.register() to resolve conflict with ctypes.
7382
Vinay Sajip51e65192008-07-18 09:01:10 +00007383- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

7386 a valid dlerror() message.
7387
Thomas Heller2bad6572008-07-15 17:19:50 +00007388- Issue #3258: Fixed a crash when a ctypes POINTER type to an
7389 incomplete structure was created.
7390
Brett Cannon3d0b9f02008-07-13 01:15:07 +00007391- Issue #3339: dummy_thread.acquire() should not return None.

7804
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007805- On MacOS X it is now possible to install the framework in 64-bit
7806 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007807 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007808
7809 This is controlled by the configure argument ``--with-universal-archs``:
7810
7811 - ``--with-universal-archs=all``: install 4-way universal
7812
7813 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7814
7815 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7816
7817 This option should be used in combination with ``--enable-universalsdk=``.
7818
7819 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

7855 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00007856
Christian Heimese74c8f22008-04-19 02:23:57 +00007857- Added kill, terminate and send_signal(sig) to subprocess.Popen.
7858
Georg Brandl3ee81df2008-05-17 18:14:43 +00007859- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
7860 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00007861

Georg Brandl3ee81df2008-05-17 18:14:43 +00007868- Issue #1631171: Re-implement the 'warnings' module in C (the
7869 original Python code has been kept as backup). This will allow for
7870 using the 'warning's machinery in such places as the parser where
7871 use of pure Python code is not possible. Both the ``showarning()``
7872 and ``formatwarning()`` gain an optional 'line' argument which is
7873 not called by default for backwards-compatibility reasons. Setting
7874 ``warnings.showwarning()`` to an implementation that lacks support
7875 for the ``line`` argument will raise a DeprecationWarning.

Thomas Hellerbf027c42008-04-24 18:14:19 +00007898 reference to themselves.
7899
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007900- The getpass module has been improved on Unix. It now uses /dev/tty
7901 by default and uses stderr instead of stdout. A GetPassWarning is
7902 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00007903

Georg Brandl3ee81df2008-05-17 18:14:43 +00007917- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007918 extension modules between 32 and 64 bit platforms. See the distutls
7919 build documentation for more information.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007938- Issue #2550: The approach used by client/server code for obtaining
7939 ports to listen on in network-oriented tests has been refined in an
7940 effort to facilitate running multiple instances of the entire
7941 regression test suite in parallel without issue.
7942 test_support.bind_port() has been fixed such that it will always
7943 return a unique port -- which wasn't always the case with the
7944 previous implementation, especially if socket options had been set
7945 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7946 new implementation of bind_port() will actually raise an exception
7947 if it is passed an AF_INET/SOCK_STREAM socket with either the
7948 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7949 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7950 the socket it's been passed. This currently only applies to
7951 Windows. This option prevents any other sockets from binding to the
7952 host/port we've bound to, thus removing the possibility of the
7953 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7954 when a second SOCK_STREAM socket binds and accepts to a host/port
7955 that's already been bound by another socket. The optional preferred
7956 port parameter to bind_port() has been removed. Under no
7957 circumstances should tests be hard coding ports!
7958
7959 test_support.find_unused_port() has also been introduced, which will
7960 pass a temporary socket object to bind_port() in order to obtain an
7961 unused port. The temporary socket object is then closed and
7962 deleted, and the port is returned. This method should only be used
7963 for obtaining an unused port in order to pass to an external program
7964 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7965 a parameter to a server-oriented class that doesn't give you direct
7966 access to the underlying socket used.
7967
7968 Finally, test_support.HOST has been introduced, which should be used
7969 for the host argument of any relevant socket calls (i.e. bind and
7970 connect).

7975 test_asynchat and test_socket_ssl.
7976

7978 suite to run in parallel without issue.

8246
Fred Drakea8ee94b2008-03-01 02:45:07 +00008247- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00008248 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00008249
Georg Brandlad61bc82008-02-23 15:11:18 +00008250- Issue #2067: file.__exit__() now calls subclasses' close() method.
8251
8252- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00008253
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008254- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00008255 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00008256
Eric Smitha73fbe72008-02-23 03:09:44 +00008257- Added the future_builtins module, which contains hex() and oct().
8258 These are the PEP 3127 version of these functions, designed to be
8259 compatible with the hex() and oct() builtins from Python 3.0. They
8260 differ slightly in their output formats from the existing, unchanged
8261 Python 2.6 builtins. The expected usage of the future_builtins
8262 module is:
8263 from future_builtins import hex, oct
8264
Eric Smith7ef40bf2008-02-20 23:34:22 +00008265- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8266 exponents for exponents with absolute value < 100. Follows C99
8267 standard. This is a change on Windows, which would use 3 digits.
8268 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8269 so that any alterations it does to the resulting string will be
8270 available in stringlib/formatter.h (for float.__format__).
8271
Eric Smith5a3c1352008-02-19 13:21:56 +00008272- Implemented PEP 3101, Advanced String Formatting. This adds a new
8273 builtin format(); a format() method for str and unicode; a
8274 __format__() method to object, str, unicode, int, long, float, and
8275 datetime; the class string.Formatter; and the C API
8276 PyObject_Format().
8277
Georg Brandl3ee81df2008-05-17 18:14:43 +00008278- Fixed several potential crashes, all caused by specially crafted
8279 __del__ methods exploiting objects in temporarily inconsistent
8280 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008281
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008282- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008283 prevent a possible crash: an Abstract Base Class would try to access
8284 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008285
Georg Brandl3ee81df2008-05-17 18:14:43 +00008286- Fixed repr() and str() of complex numbers with infinity or nan as
8287 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00008288
Georg Brandl3ee81df2008-05-17 18:14:43 +00008289- Clear all free lists during a gc.collect() of the highest generation
8290 in order to allow pymalloc to free more arenas. Python may give back
8291 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008292
Georg Brandl3ee81df2008-05-17 18:14:43 +00008293- Issue #2045: Fix an infinite recursion triggered when printing a
8294 subclass of collections.defaultdict, if its default_factory is set
8295 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008296
Christian Heimesf75dbef2008-02-08 00:11:31 +00008297- Fixed a minor memory leak in dictobject.c. The content of the free
8298 list was not freed on interpreter shutdown.
8299
Georg Brandl21e99f42010-03-07 15:23:59 +00008300- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008301 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008302
Georg Brandl3ee81df2008-05-17 18:14:43 +00008303- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8304 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008305 to compact the internal free lists of pre-allocted ints and floats.
8306
Georg Brandl3ee81df2008-05-17 18:14:43 +00008307- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8308 calls. Python expected the return type int but the fork familie
8309 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008310
Georg Brandl3ee81df2008-05-17 18:14:43 +00008311- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8312 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008313
Georg Brandl3ee81df2008-05-17 18:14:43 +00008314- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8315 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00008316
Georg Brandl3ee81df2008-05-17 18:14:43 +00008317- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8318 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00008319
Georg Brandl3ee81df2008-05-17 18:14:43 +00008320- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8321 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008322
Georg Brandl3ee81df2008-05-17 18:14:43 +00008323- Patch #1473257: generator objects gain a gi_code attribute. This is
8324 the same object as the func_code attribute of the function that
8325 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008326
Georg Brandl3ee81df2008-05-17 18:14:43 +00008327- Issue #1920: "while 0" statements were completely removed by the
8328 compiler, even in the presence of an "else" clause, which is
8329 supposed to be run when the condition is false. Now the compiler
8330 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008331
Guido van Rossumeead05f2008-01-24 18:21:02 +00008332- A few crashers fixed: weakref_in_del.py (issue #1377858);
8333 loosing_dict_ref.py (issue #1303614, test67.py);
8334 borrowed_ref_[34].py (not in tracker).
8335
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008336- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008337 suppressed while an extension is loaded by calling SetErrorMode in
8338 dynload_win.c. The error is still reported properly.
8339
Georg Brandl3ee81df2008-05-17 18:14:43 +00008340- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008341 several extension methods and modules do not work without unicode
8342 support.
8343
Georg Brandl26543b12008-01-21 18:36:51 +00008344- Issue #1882: when compiling code from a string, encoding cookies in the
8345 second line of code were not always recognized correctly.
8346
Georg Brandl14404b62008-01-19 19:27:05 +00008347- Issue #1679: "0x" was taken as a valid integer literal.
8348
Georg Brandl6caad7d2008-01-26 14:19:22 +00008349- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008350 added.
8351
Christian Heimesc94e2b52008-01-14 04:13:37 +00008352- sys.float_info / PyFloat_GetInfo: The floating point information
8353 object was converted from a dict to a specialized structseq object.
8354
Georg Brandl3ee81df2008-05-17 18:14:43 +00008355- Patch #1816: Added sys.flags structseq. It exposes the status of
8356 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008357
Georg Brandl3ee81df2008-05-17 18:14:43 +00008358- Objects/structseq.c: Implemented new structseq representation. The
8359 patch makes structseqs (e.g. the return value of os.stat) more
8360 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008361
Georg Brandl3ee81df2008-05-17 18:14:43 +00008362- Patch #1700288: added a type attribute cache that caches method
8363 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008364
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008365- Bug #1776: __import__() no longer accepts filenames on any platform.
8366 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008367

8369
Georg Brandl3ee81df2008-05-17 18:14:43 +00008370- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8371 envvar and sys.dont_write_bytecode attribute. All these can be set
8372 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008373
Georg Brandl3ee81df2008-05-17 18:14:43 +00008374- Improve some exception messages when Windows fails to load an
8375 extension module. Now we get for example '%1 is not a valid Win32
8376 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008377
Georg Brandl3ee81df2008-05-17 18:14:43 +00008378- Bug #1481296: Fixed long(float('nan')) != 0L.

8381 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008382
Christian Heimes0a8143f2007-12-18 23:22:54 +00008383- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008384 and INF. float("nan"), float("inf") and float("-inf") now work on
8385 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008386
Georg Brandl3ee81df2008-05-17 18:14:43 +00008387- Compiler now generates simpler and faster code for dictionary
8388 literals. The oparg for BUILD_MAP now indicates an estimated
8389 dictionary size. There is a new opcode, STORE_MAP, for adding
8390 entries to the dictionary.

8422 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008423
Georg Brandl3ee81df2008-05-17 18:14:43 +00008424- Issue #1265: Fix a problem with sys.settrace, if the tracing
8425 function uses a generator expression when at the same time the
8426 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008427
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008428- sets and frozensets now have an isdisjoint() method.
8429
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008430- optimize the performance of builtin.sum().

8433
Georg Brandl21e99f42010-03-07 15:23:59 +00008434- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008435 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8436 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008437
Georg Brandl3ee81df2008-05-17 18:14:43 +00008438- Issue #1686386: Tuple's tp_repr did not take into account the
8439 possibility of having a self-referential tuple, which is possible
8440 from C code. Nor did object's tp_str consider that a type's tp_str
8441 could do something that could lead to an inifinite recursion.
8442 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8443 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008444
Georg Brandl3ee81df2008-05-17 18:14:43 +00008445- Issue #1164: It was possible to trigger deadlock when using the
8446 'print' statement to write to a file since the GIL was not released
8447 as needed. Now PyObject_Print() does the right thing along with
8448 various tp_print implementations of the built-in types and those in
8449 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008451- Issue #1147: Exceptions were directly allowing string exceptions in
8452 their throw() method even though string exceptions no longer
8453 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +00008458- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008459 PyObject_Call() never calling back out to Python code to trigger
8460 recursion depth updates/checks. Required the creation of a static
8461 RuntimeError instance in case normalizing an exception put the
8462 recursion check value past its limit. Fixes crashers
8463 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00008478- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008479 __*__ attributes. (Some already existed, e.g., __doc__ and
8480 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008481
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008482- Add -3 option to the interpreter to warn about features that are

8486 calls.
8487
Collin Winter62903052007-05-18 23:11:24 +00008488- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008489 "except E as target:". This is to provide forwards compatibility
8490 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008491
Brett Cannon229cee22007-05-05 01:34:02 +00008492- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008497- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008498 setting a plain string, ie don't expand to single letter identifiers.
8499
Raymond Hettinger13936692007-04-11 18:40:58 +00008500- Request #1191699: Slices can now be pickled.
8501
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008502- Request #1193128: str.translate() now allows a None argument for
8503 translations that only remove characters without re-mapping the
8504 remaining characters.
8505
Georg Brandl5cb76c12007-03-21 09:00:39 +00008506- Patch #1682205: a TypeError while unpacking an iterable is no longer

8510
Guido van Rossum143b5642007-03-23 04:58:42 +00008511- Bug #1683368: The object.__init__() and object.__new__() methods are
8512 now stricter in rejecting excess arguments. The only time when
8513 either allows excess arguments is when it is not overridden and the
8514 other one is. For backwards compatibility, when both are
8515 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008516 warning later). Also, type.__init__() insists on the same signature
8517 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008518
Georg Brandl3ee81df2008-05-17 18:14:43 +00008519- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8520 object to complex using its __complex__() method before falling back
8521 to the __float__() method. Therefore, the functions in the cmath
8522 module now can operate on objects that define a __complex__()
8523 method.

8534 its type.

Georg Brandl7b9c5552007-03-12 14:30:05 +00008541- Bug #1678647: write a newline after printing an exception in any
8542 case, even when converting the value to a string failed.
8543
Georg Brandl871f1bc2007-03-12 13:17:36 +00008544- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008545 its argument, if it exists. If not, it will work like before. This
8546 allows customizing the output of dir() in the presence of a
8547 __getattr__().

8556 parthensized forms. This means complex(repr(x)) now works instead of
8557 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008558
Georg Brandlaa2321b2007-03-07 00:40:28 +00008559- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008560 makes the filenames the warning module prints much more sensible
8561 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00008574- Patch #1674228: when assigning a slice (old-style), check for the
8575 sq_ass_slice instead of the sq_slice slot.
8576
Georg Brandl3ee81df2008-05-17 18:14:43 +00008577- When printing an unraisable error, don't print exceptions. before

9187 Python would crash instead of raising an error.
9188

9204 accepted in TestSuite.addTest(). This should cause no
9205 incompatibility since it never made sense with ordinary subclasses
9206 -- the failure just occurred later, with a more cumbersome
9207 exception.

9485 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009486
Georg Brandl3ee81df2008-05-17 18:14:43 +00009487- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009488 that the SMTP.starttls() caller no longer needs to call ehlo()
9489 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009490 does not claim to support starttls. Adds the
9491 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00009590 time so that opening a database previously created with the DB_DUP
9591 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9592 opens. Specifically: dictionary assignment to a DB object will
9593 replace all values for a given key when the database allows
9594 duplicate values. DB users should use DB.put(k, v) when they want
9595 to store duplicates; not DB[k] = v.

9602 characters with ASCII value less than 32. Also, it correctly quotes
9603 dots only if they occur on a single line, as opposed to the previous
9604 behavior of quoting dots if they are the second character of any
9605 line.

9933-----
9934
Georg Brandl3ee81df2008-05-17 18:14:43 +00009935- Unified naming convention for free lists and their limits. All free
9936 lists in Object/ are named ``free_list``, the counter ``numfree``
9937 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
9938 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009939
Georg Brandl3ee81df2008-05-17 18:14:43 +00009940- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9941 to ``PyTuple_SetItem``, it can be used to populate a brand new
9942 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00009943
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009944- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009946- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
9947 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
9948 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009949
9950- Patch #1720595: add T_BOOL to the range of structmember types.
9951
9952- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9953 ``PyFloat_GetInfo()`` to the float API.
9954
Georg Brandl3ee81df2008-05-17 18:14:43 +00009955- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9956 of w# format code incorrectly truncated the length to an int, even
9957 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9958 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009959
Georg Brandl3ee81df2008-05-17 18:14:43 +00009960- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

9968 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009969
9970- Patch #1733960: Allow T_LONGLONG to accept ints.

9978- Fix some leftovers from the conversion from int to Py_ssize_t
9979 (relevant to strings and sequences of more than 2**31 items).
9980
9981- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9982 outside of pystate.c and should not be necessary.
9983
Georg Brandl3ee81df2008-05-17 18:14:43 +00009984- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9985 absolute imports. In earlier versions they might have used relative
9986 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009987
Georg Brandl3ee81df2008-05-17 18:14:43 +00009988- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9989 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009990
Georg Brandl3ee81df2008-05-17 18:14:43 +00009991- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00009997- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
9998 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
9999 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10000 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010001
Georg Brandl3ee81df2008-05-17 18:14:43 +000010002- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +000010014- Removed the macfs module. It had been deprecated since Python 2.5.
10015 This lead to the deprecation of macostools.touched() as it relied
10016 solely on macfs and was a no-op under OS X.
