Ned Deily18fae3f2013-01-31 01:24:55 -08001743- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1744 In particular, fix extension module build failures when trying to use
1745 32-bit-only installer Pythons on systems with Xcode 4 (currently
1746 OS X 10.8, 10.7, and optionally 10.6).
1747 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1748 * Since Xcode 4 removes ppc support, extension module builds now
1749 check for ppc compiler support and by default remove ppc and
1750 ppc64 archs when they are not available.
1751 * Extension module builds now revert to using system installed
1752 headers and libs (/usr and /System/Library) if the SDK used
1753 to build the interpreter is not installed or has moved.
1754 * Try to avoid building extension modules with deprecated
1755 and problematic Apple llvm-gcc compiler. If original compiler
1756 is not available, use clang instead by default.

2108 int.__pow__. These overflow checks were causing int.__pow__ to produce
2109 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01002110 compiler optimizing the check away. Also fix similar overflow checks
2111 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

2124 cleared by the garbage collector. This fixes a segfault when an instance
2125 and its type get caught in a reference cycle, and the instance's
2126 deallocator calls one of the methods on the type (e.g. when subclassing

Florent Xiclunac2279652012-02-12 14:49:03 +01002180- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002181 has left two versions of customize_compiler, the original in
2182 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01002187- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2188 Distutils-based packages with C extension modules may fail because
2189 Apple has removed gcc-4.2, the version used to build python.org
2190 64-bit/32-bit Pythons. If the user does not explicitly override
2191 the default C compiler by setting the CC environment variable,
2192 Distutils will now attempt to compile extension modules with clang
2193 if gcc-4.2 is required but not found. Also as a convenience, if
2194 the user does explicitly set CC, substitute its value as the default
2195 compiler in the Distutils LDSHARED configuration variable for OS X.
2196 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2197 SDK, neither of which are available in Xcode 4. This change does not
2198 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002448- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2449 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2450 interpreter process. This could cause failures in non-Distutils subprocesses
2451 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002452 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002453 deployment target only in the environment of each build subprocess. It is
2454 still possible to globally override the default by setting
2455 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2456 greater or equal to the default value, the value with which the interpreter
2457 was built.

Barry Warsawc5643282011-07-19 17:06:30 -04002485- sys.setcheckinterval() now updates the current ticker count as well as
2486 updating the check interval, so if the user decreases the check interval,
2487 the ticker doesn't have to wind down to zero from the old starting point
2488 before the new interval takes effect. And if the user increases the
2489 interval, it makes sure the new limit takes effect right away rather have an
2490 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00003470- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3471 This prevents user-created self-referencing ordered dictionaries from
3472 becoming permanently uncollectable GC garbage. The downside is that

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003933- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the

3935 of the number of bytes specified by the start byte.
3936 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3937 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3938 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

3948 objects. (1) The comparison could incorrectly return True in some cases
3949 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

4092 non-float non-integer argument is now converted to an integer (if possible)
4093 using its __int__ method. Previously, only small arguments were treated this
4094 way; larger arguments (those whose __int__ was outside the range of a C long)

4146 operation raises multiple signals and more than one of those signals is
4147 trapped, the specification determines the order in which the signals should be
4148 handled. In many cases this order wasn't being followed, leading to the wrong

Georg Brandlfee0f442010-05-22 21:26:21 +00004293- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00004294 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
4295 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
4296 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

4316Core and Builtins
4317-----------------
4318
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004319- Issue #7301: Add environment variable $PYTHONWARNINGS.
4320
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004321- Issue #8329: Don't return the same lists from select.select when no fds are
4322 changed.
4323
Georg Brandlfee0f442010-05-22 21:26:21 +00004324- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004325 on 64-bit machines. The shift count for either left or right shift is
4326 permitted to be up to sys.maxsize.
4327
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004328- Ensure that tokenization of identifiers is not affected by locale.
4329
Georg Brandlfee0f442010-05-22 21:26:21 +00004330- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00004331
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00004332- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
4333
Georg Brandlfee0f442010-05-22 21:26:21 +00004334- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4335 with a non-empty format string. This is an effort to future-proof user
4336 code. If a derived class does not currently implement __format__ but later
4337 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004338 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004339 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004340
Antoine Pitroua57df2c2010-03-31 21:32:15 +00004341- Issue #8268: Old-style classes (not just instances) now support weak
4342 references.
4343
Georg Brandlfee0f442010-05-22 21:26:21 +00004344- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
4345 is set.

Benjamin Peterson96545892010-03-21 20:21:00 +00004349- Issue #6474: Make error message from passing an inadequate number of keyword
4350 arguments to a function correct.
4351
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00004352- Issue #8164: Don't allow lambda functions to have a docstring.
4353
Victor Stinner66644262010-03-10 22:30:19 +00004354- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00004355 (SIGINT). If an error occurs while importing the site module, the error is
4356 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00004357 module.

Antoine Pitrouf9de5342010-04-05 21:35:07 +00004366- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00004367 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
4368 `ssl.OPENSSL_VERSION_NUMBER`.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00004370- Issue #8310: Allow dis to examine new style classes.
4371
Georg Brandlfee0f442010-05-22 21:26:21 +00004372- Issue #8257: The Decimal construct now accepts a float instance directly,
4373 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004374
4375 >>> Decimal(1.1)
4376 Decimal('1.100000000000000088817841970012523233890533447265625')
4377
Raymond Hettinger34c35b22010-04-03 10:22:00 +00004378- collections.Counter() now supports a subtract() method.
4379
Georg Brandlfee0f442010-05-22 21:26:21 +00004380- The functools module now has a total_ordering() class decorator to simplify
4381 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00004382
Georg Brandlfee0f442010-05-22 21:26:21 +00004383- The functools module also adds cmp_to_key() as a tool to transition old-style
4384 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00004385
Georg Brandlfee0f442010-05-22 21:26:21 +00004386- Issue #8294: The Fraction constructor now accepts Decimal and float instances
4387 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00004388
Georg Brandlfee0f442010-05-22 21:26:21 +00004389- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4390 InvalidOperation instead of returning False. (Comparisons involving a quiet
4391 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4392 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004393
Georg Brandlfee0f442010-05-22 21:26:21 +00004394- Issue #2531: Comparison operations between floats and Decimal instances now
4395 return a result based on the numeric values of the operands; previously they
4396 returned an arbitrary result based on the relative ordering of id(float) and
4397 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004398
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004399- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004400 argument `-` which tells it to read files to compile from stdin. Each line is
4401 read on demand and the named file is compiled immediately. (Original patch by
4402 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004403
Georg Brandlfee0f442010-05-22 21:26:21 +00004404- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
4405 function like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +00004406
Florent Xicluna58b65662010-03-30 16:29:03 +00004407- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4408 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004409 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00004410
Georg Brandlfee0f442010-05-22 21:26:21 +00004411- Comparisons using one of <, <=, >, >= between a complex instance and a
4412 Fractions instance now raise TypeError instead of returning True/False. This
4413 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4414 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00004415
Michael Foorde6410c52010-03-29 20:04:23 +00004416- Addition of ``WeakSet`` to the ``weakref`` module.

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004425- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00004426 didn't support chflags() (for example ZFS under FreeBSD). The error is now
4427 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004428
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00004429- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
4430 deprecated.
4431
Georg Brandlfee0f442010-05-22 21:26:21 +00004432- Issue #7860: platform.uname now reports the correct 'machine' type when Python
4433 is running in WOW64 mode on 64 bit Windows.

4446 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
4447 reads and writes are always retried by OpenSSL itself.

4455 memoryviews.
Antoine Pitroud7b731d2010-03-17 22:45:39 +00004456
Matthias Klose8b411682010-03-16 10:48:52 +00004457- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
4458 with Tcl/Tk-8.5.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00004469- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00004470 for ``TimedRotatingFileHandler`` by using the modification time of an existing
4471 log file to compute the next rollover time. If the log file does not exist,
4472 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00004473
Georg Brandlba83f822010-03-14 09:50:54 +00004474- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Georg Brandlba83f822010-03-14 09:50:54 +00004482- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
4483 a base64 transfer-encoded payload *after* decoding it; it no longer does.
4484 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +00004513- Issue #8300: When passing a non-integer argument to struct.pack with any
4514 integer format code, struct.pack first attempts to convert the non-integer
4515 using its __index__ method. If that method is non-existent or raises
4516 TypeError it goes on to try the __int__ method, as described below.
4517
Georg Brandlba83f822010-03-14 09:50:54 +00004518- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4519 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4520 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004521 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4522 inconsistent: __int__ was used for some integer codes but not for others, and
4523 the set of integer codes for which it was used differed between native packing

4756 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00004757 library would return a bogus result; on Solaris, it was possible to crash the

Georg Brandlba83f822010-03-14 09:50:54 +00004776- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4777 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4778 returning NULL. The macro now returns a statically allocated empty string
4779 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00004832 file position when calling `truncate()`. It would previously change the file
4833 position to the given argument, which goes against the tradition of

4837 class used to represent files stored inside an archive. The new
4838 implementation is significantly faster and can be wrapped in a
4839 ``io.BufferedReader`` object for more speedups. It also solves an issue
4840 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

4853 encoded string for them. This ensures that the upload and register commands
4854 send the correct values to PyPI without any error.

4929-----------------
4930
Georg Brandlba83f822010-03-14 09:50:54 +00004931- The ``__complex__()`` method is now looked up on the class of instances to
4932 make it consistent with other special methods.

4936
Mark Dickinson1b34d252010-01-01 17:27:30 +00004937- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004938 DeprecationWarning when passed a float argument where an integer was expected.
4939 These functions and methods now raise TypeError instead. The majority of the
4940 effects of this change are in the extension modules, but some core functions
4941 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4942 and many unicode/str methods.

4956 of integers: the result of a/b is now correctly rounded for ints a and b (at
4957 least on IEEE 754 platforms), and in particular does not depend on the
4958 internal representation of a long.

4966
Georg Brandlba83f822010-03-14 09:50:54 +00004967 These executables now work properly with the arch(1) command: ``arch -ppc
4968 python`` will start a universal binary version of python in PPC mode (unlike

5108 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005109
Georg Brandlba83f822010-03-14 09:50:54 +00005110- Remove switch from "%f" formatting to "%g" formatting for floats larger than
5111 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00005112
Georg Brandlba83f822010-03-14 09:50:54 +00005113- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
5114 1e-100 used to raise OverflowError, but now gives the requested 120
5115 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00005123
Georg Brandlba83f822010-03-14 09:50:54 +00005124- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5125 decimal string that's guaranteed to round back to x under correct rounding
5126 (with round-half-to-even rounding mode). Previously it gave a string based on
5127 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5128 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5129 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005130
Georg Brandlba83f822010-03-14 09:50:54 +00005131- Issue #7117: On almost all platforms: float-to-string and string-to-float
5132 conversions within Python are now correctly rounded. Places these conversions
5133 occur include: str for floats and complex numbers; the float and complex
5134 constructors; old-style and new-style numeric formatting; serialization and
5135 deserialization of floats and complex numbers using marshal, pickle and json;
5136 parsing of float and imaginary literals in Python code; Decimal-to-float
5137 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005138
Georg Brandlba83f822010-03-14 09:50:54 +00005139 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5140 providing correctly-rounded strtod and dtoa C functions. This code is
5141 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5142 the C compiler. There may be a small number of platforms on which correct
5143 operation of this code cannot be guaranteed, so the code is not used: notably,
5144 this applies to platforms where the C double format is not IEEE 754 binary64,
5145 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5146 and Python's configure script is unable to determine how to change the FPU
5147 precision. On these platforms conversions use the platform strtod and dtoa,
5148 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005149
Georg Brandlba83f822010-03-14 09:50:54 +00005150- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5151 uses the correctly-rounded string <-> float conversions described above (when
5152 available), and so produces correctly rounded results that will display nicely
5153 under the float repr. There are two related small changes: (1) round now
5154 accepts any class with an ``__index__()`` method for its second argument (but
5155 no longer accepts floats for the second argument), and (2) an excessively
5156 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5157 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005304- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5305 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5306 but with at least one decimal point and with a default precision
5307 of 12. Previously, the behavior the same but with a default precision of 6.
5308 This more closely matches ``str()``, and reduces surprises when adding
5309 alignment flags to the empty presentation type. This also affects the new
5310 complex.__format__ in the same way.

5507
Georg Brandlba83f822010-03-14 09:50:54 +00005508- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5509 file objects with closefd=False. The file descriptor is still kept open but
5510 the file object behaves like a closed file. The ``FileIO`` object also got a
5511 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005531- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00005534- On windows, ``os.chdir()`` given unicode was not working if
5535 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5536 this code path is really executed because I cannot move to such directory on
5537 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00005539- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5540 element is temporarily replaced with an equivalent frozenset. But the
5541 eventual KeyError would always report the empty ``frozenset()`` as the missing
5542 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00005562- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5563 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5564 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5565 of using the replace error handler in PyUnicode_DecodeUTF8().
5566
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005567- Issue #3739: The unicode-internal encoder now reports the number of characters

5569
Georg Brandlba83f822010-03-14 09:50:54 +00005570- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
5571 allocator will be automatically disabled when running under Valgrind. This
5572 gives improved memory leak detection when running under Valgrind, while taking
5573 advantage of pymalloc at other times.

6819 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00006820 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
6821 the tests if DISPLAY is defined but can't be used.

6829 C and Python implementations in the stdlib can be adjusted to use it over
6830 time.

6942
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006943- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6944 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6945 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6946 ``printf`` function, whereas PyString_FromFormat has an independent
6947 implementation and uses "%zd" on all platforms for size_t values.
6948 This makes a difference on win64, where ``printf`` needs "%Id" to display
6949 64bit values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006966 was correctly parsed but parsing of subsequent arguments failed.
6967
Vinay Sajip35e3b032008-09-01 14:33:59 +00006968- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006969 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6970 mechanism. In the process, fix a bug where isinstance() and issubclass(),

6972 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6973 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007112What's New in Python 2.6 beta 3?
7113================================
7114
Barry Warsaw07a4a382008-08-21 01:15:08 +00007115*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007116
7117Core and Builtins
7118-----------------
7119
Guido van Rossumf8402962008-08-20 15:01:50 +00007120- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7121 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7122 extensions do not automatically benefit from the class attribute
7123 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7124 to their tp_flags field if they care. This is a backwards
7125 compatibility feature; in 3.0, all types will use the cache by
7126 default.
7127
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007128- Keyword arguments can now follow starred arguments. (``f(a, *args,
7129 keyword=23)`` is now valid syntax.)
7130
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007131- ctypes function pointers that are COM methods have a boolean True
7132 value again.
7133
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007134- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7135 by denying s# to parse objects that have a releasebuffer procedure,
7136 and introducing s*.
7137
Georg Brandl1e13ea92008-08-11 09:07:59 +00007138- Issue #3537: Fix an assertion failure when an empty but presized dict
7139 object was stored in the freelist.
7140
Mark Dickinsonb6467572008-08-04 21:30:09 +00007141- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7142 ValueError consistently across platforms.
7143
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007144- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7145 (64bit Unix, for example), unichr() would truncate its argument and return
7146 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7147
Neal Norwitze7d8be82008-07-31 17:17:14 +00007148- Apply security patches from Apple.
7149
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007150- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7151 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7152
Antoine Pitrou92f82162008-07-25 22:22:08 +00007153- Issue #1819: function calls with several named parameters are now on
7154 average 35% faster (as measured by pybench).
7155
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007156- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7157 the python debugger steps into a class statement: the free variables (local
7158 variables defined in an outer scope) would be deleted from the outer scope.
7159
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007160- Issue #2620: Overflow checking when allocating or reallocating memory
7161 was not always being done properly in some python types and extension
7162 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7163 all been updated to perform better checks and places in the code that
7164 would previously leak memory on the error path when such an allocation
7165 failed have been fixed.
7166
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007167Library
7168-------
7169
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007170- Issue #3612: Added some missing basic types in ctypes.wintypes.
7171
Benjamin Petersone977ad42008-08-20 01:42:01 +00007172- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7173 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7174
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007175- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7176 version reported by these tools does not necessarily follow the python
7177 version numbering scheme, so the module is less strict when parsing it.
7178
Nick Coghlanf70385a2008-08-18 12:42:46 +00007179- Issue #2235: Added Py3k warnings for types which will become unhashable
7180 under the stricter __hash__ inheritance rules in 3.0. Several types
7181 which did not meet the rules for hash invariants and were already
7182 unhashable in 3.0 have now been explicitly flagged as unhashable in
7183 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7184 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7185
Brett Cannon88f801d2008-08-18 00:46:22 +00007186- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7187 imported into the module but exposed as part of the module's API.
7188
Brett Cannon7b96f072008-08-18 00:41:11 +00007189- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7190
Brett Cannon46225e72008-08-18 00:36:52 +00007191- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
7192
Brett Cannon25c9d6a2008-08-17 22:10:11 +00007193- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7194
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007195- Issue #3575: Incremental decoder's decode function now takes bytearray
7196 by using 's*' instead of 't#'.
7197
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007198- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007199 fails unicode conversion on 2nd parameter. (windows only)
7200
Georg Brandl222e2082010-08-01 22:27:39 +00007201- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007202 in a redirect.
7203
Brett Cannonabe423e2008-08-16 21:47:07 +00007204- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007205 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007206
Facundo Batistaeb90b782008-08-16 14:44:07 +00007207- Issue #2776: fixed small issue when handling an URL with double slash
7208 after a 302 response in the case of not going through a proxy.
7209
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007210- Issue #2676: in the email package, content-type parsing was hanging on
7211 pathological input because of quadratic or exponential behaviour of a
7212 regular expression.
7213
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007214- Issue #3476: binary buffered reading through the new "io" library is now
7215 thread-safe.
7216
Brett Cannonbf3157b2008-08-14 05:00:03 +00007217- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7218 since mimetools itself is deprecated. Because modules are cached, all
7219 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7220
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007221- Issue #3134: shutil referenced undefined WindowsError symbol.
7222
Robert Schuppenies14646332008-08-10 11:01:53 +00007223- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7224 menu entries were not deleted.
7225
Brett Cannon83e81842008-08-09 23:30:55 +00007226- Copied the implementation of reduce() to _functools.reduce() to have a
7227 version that did not raise a DeprecationWarning under -3.
7228
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007229- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7230 a MemoryError rather than silently stop the iteration.
7231
Guido van Rossum59ce9012008-08-09 14:55:34 +00007232- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7233 to _sre.compile() will now be rejected. This should not affect anybody
7234 since the re.compile() function never generates invalid re-bytecode.
7235
Skip Montanaroa032bf42008-08-08 22:52:51 +00007236- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7237 upon first access it can be automatically initialized from the csv file if
7238 it wasn't initialized during instantiation.
7239
Brett Cannon3aa2a492008-08-06 22:28:09 +00007240- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7241 the reload() built-in has been removed.
7242
Brett Cannon7e30b672008-08-04 21:52:25 +00007243- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007244 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00007245 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
7246 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
7247 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
7248 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
7249 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00007250
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00007251- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
7252 raised an AttributeError.
7253
Benjamin Peterson01a24322008-07-28 23:35:27 +00007254- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00007255 asking for a specific length. This problem only affected files opened
7256 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007257
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00007258- Issue #3449: Update decimal module to use most recent specification
7259 (v. 1.68) and tests (v. 2.58) from IBM.
7260
Georg Brandl222e2082010-08-01 22:27:39 +00007261- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00007262
Georg Brandl222e2082010-08-01 22:27:39 +00007263- Issue #1592: Improve error reporting when operations are attempted
Raymond Hettinger8c664e82008-07-25 18:43:33 +00007264 on a closed shelf.
7265
Georg Brandlf9efabb2008-07-23 15:16:45 +00007266- Deprecate the "ast" parser function aliases.
7267
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007268- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
7269
7270- Issue #3303: Fix a crash in locale.strcoll() when calling it with
7271 invalid arguments.
7272
7273- Issue #3302: Fix several crashes when calling locale's gettext functions
7274 with None arguments.
7275
7276- Issue #3389: Allow resolving dotted names for handlers in logging
7277 configuration files.
7278
7279- Deprecate the sunaudio module for removal in Python 3.0.
7280
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00007281- Issue #3394: zipfile.writestr sets external attributes when passed a
7282 file name rather than a ZipInfo instance, so files are extracted with
7283 mode 0600 rather than 000 under Unix.
7284
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007285- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7286 argument in python 2.5, this broke code that subclassed Popen to include its
7287 own poll method. Fixed my moving _deadstate to an _internal_poll method.

7295-------------
7296
Nick Coghlan6e8fef02008-08-18 13:14:22 +00007297- Issue #2235: the C API function PyObject_HashNotImplemented and its
7298 interaction with the tp_hash slot (added in 2.6b2) are now documented
7299
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007300- Issue #643841: The language reference now provides more detailed
7301 coverage of the lookup process for special methods. The disclaimers
7302 regarding lack of coverage of new-style classes have also been
7303 removed, since the coverage is now fairly reasonable.

7307================================
7308
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007309*Release date: 17-Jul-2008*
7310
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007311Core and Builtins
7312-----------------
7313
Georg Brandl3e483f62008-07-16 22:57:41 +00007314- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7315 its methods now allow for items objects that can be converted to
7316 an integer using operator.index().
7317
Mark Dickinson64b7e502008-07-16 09:40:03 +00007318- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7319 produced a ValueError instead of giving the correct float.
7320
Eric Smitha5fa5a22008-07-16 00:11:49 +00007321- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7322 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7323
Mark Dickinson7103aa42008-07-15 19:08:33 +00007324- Issue #3008: the float type has a new instance method 'float.hex'
7325 and a new class method 'float.fromhex' to convert floating-point
7326 numbers to and from hexadecimal strings, respectively.
7327
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007328- Issue #2235: __hash__ is once again inherited by default. To allow
7329 collections.Hashable to remain meaningful in the presence of the
7330 default hash implementation (object.__hash__), it is now possible
7331 to explicit block inheritance of hash by setting __hash__=None at
7332 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7333 level.
7334
Nick Coghlanb028f502008-07-13 14:52:36 +00007335- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7336 the parent module cannot be found while performing an absolute import.
7337 This means that an incorrectly defined __package__ attribute will
7338 now only prevent relative imports in that module rather than causing
7339 all imports from that module to fail.
7340
Nick Coghlan14ff9942008-07-08 14:21:42 +00007341- Issue #2517: Allow unicode messages in Exceptions again by correctly
7342 bypassing the instance dictionary when looking up __unicode__ on
7343 new-style classes.
7344
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007345- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7346 set to a custom object whose write() method happens to install
7347 another file in sys.stdout.
7348
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007349- Issue #3088: Corrected a race condition in classes derived from
7350 threading.local: the first member set by a thread could be saved in
7351 another thread's dictionary.
7352
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007353- Issue #3004: Minor change to slice.indices(): the start and stop
7354 arguments are now treated identically, making the behaviour easier
7355 to describe and understand. For example, slice(None, -10,
7356 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7357 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7358 10, -1).
7359
Georg Brandl278fc502008-07-19 12:46:12 +00007360- Issue #3219: Calling a function with repeated keyword arguments,
7361 f(a=2, a=23), would not cause a syntax error. This was a regression
7362 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007363
Georg Brandl278fc502008-07-19 12:46:12 +00007364- Issue #2862: Make int and float freelist management consistent with
7365 other freelists. Changes their CompactFreeList apis into
7366 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00007371- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
7372 api functions without holding the GIL, which could lead to a fatal
7373 error when they failed.
7374
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007375- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

7389 a valid dlerror() message.
7390
Thomas Heller2bad6572008-07-15 17:19:50 +00007391- Issue #3258: Fixed a crash when a ctypes POINTER type to an
7392 incomplete structure was created.

7807
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007808- On MacOS X it is now possible to install the framework in 64-bit
7809 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007810 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007811
7812 This is controlled by the configure argument ``--with-universal-archs``:
7813
7814 - ``--with-universal-archs=all``: install 4-way universal
7815
7816 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7817
7818 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7819
7820 This option should be used in combination with ``--enable-universalsdk=``.
7821
7822 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

7858 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00007859
Christian Heimese74c8f22008-04-19 02:23:57 +00007860- Added kill, terminate and send_signal(sig) to subprocess.Popen.
7861
Georg Brandl3ee81df2008-05-17 18:14:43 +00007862- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
7863 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00007864

Georg Brandl3ee81df2008-05-17 18:14:43 +00007871- Issue #1631171: Re-implement the 'warnings' module in C (the
7872 original Python code has been kept as backup). This will allow for
7873 using the 'warning's machinery in such places as the parser where
7874 use of pure Python code is not possible. Both the ``showarning()``
7875 and ``formatwarning()`` gain an optional 'line' argument which is
7876 not called by default for backwards-compatibility reasons. Setting
7877 ``warnings.showwarning()`` to an implementation that lacks support
7878 for the ``line`` argument will raise a DeprecationWarning.

Neal Norwitz2b0bea52008-04-25 03:40:17 +00007900- Issue #2682: ctypes callback functions no longer contain a cyclic
Thomas Hellerbf027c42008-04-24 18:14:19 +00007901 reference to themselves.
7902
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007903- The getpass module has been improved on Unix. It now uses /dev/tty
7904 by default and uses stderr instead of stdout. A GetPassWarning is
7905 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00007906

7917 implementation detail of the public ``types`` module, has been
7918 removed and replaced by pure python code.
Amaury Forgeot d'Arc02f33b42008-04-08 23:10:07 +00007919
Georg Brandl3ee81df2008-05-17 18:14:43 +00007920- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007921 extension modules between 32 and 64 bit platforms. See the distutls
7922 build documentation for more information.

7934 so the controlled environment will more closely mirror the typical
7935 script environment. This supports setup.py scripts that refer to
7936 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007941- Issue #2550: The approach used by client/server code for obtaining
7942 ports to listen on in network-oriented tests has been refined in an
7943 effort to facilitate running multiple instances of the entire
7944 regression test suite in parallel without issue.
7945 test_support.bind_port() has been fixed such that it will always
7946 return a unique port -- which wasn't always the case with the
7947 previous implementation, especially if socket options had been set
7948 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7949 new implementation of bind_port() will actually raise an exception
7950 if it is passed an AF_INET/SOCK_STREAM socket with either the
7951 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7952 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7953 the socket it's been passed. This currently only applies to
7954 Windows. This option prevents any other sockets from binding to the
7955 host/port we've bound to, thus removing the possibility of the
7956 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7957 when a second SOCK_STREAM socket binds and accepts to a host/port
7958 that's already been bound by another socket. The optional preferred
7959 port parameter to bind_port() has been removed. Under no
7960 circumstances should tests be hard coding ports!
7961
7962 test_support.find_unused_port() has also been introduced, which will
7963 pass a temporary socket object to bind_port() in order to obtain an
7964 unused port. The temporary socket object is then closed and
7965 deleted, and the port is returned. This method should only be used
7966 for obtaining an unused port in order to pass to an external program
7967 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7968 a parameter to a server-oriented class that doesn't give you direct
7969 access to the underlying socket used.
7970
7971 Finally, test_support.HOST has been introduced, which should be used
7972 for the host argument of any relevant socket calls (i.e. bind and
7973 connect).

8249
Fred Drakea8ee94b2008-03-01 02:45:07 +00008250- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00008251 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00008252
Georg Brandlad61bc82008-02-23 15:11:18 +00008253- Issue #2067: file.__exit__() now calls subclasses' close() method.
8254
8255- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00008256
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008257- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00008258 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00008259
Eric Smitha73fbe72008-02-23 03:09:44 +00008260- Added the future_builtins module, which contains hex() and oct().
8261 These are the PEP 3127 version of these functions, designed to be
8262 compatible with the hex() and oct() builtins from Python 3.0. They
8263 differ slightly in their output formats from the existing, unchanged
8264 Python 2.6 builtins. The expected usage of the future_builtins
8265 module is:
8266 from future_builtins import hex, oct
8267
Eric Smith7ef40bf2008-02-20 23:34:22 +00008268- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8269 exponents for exponents with absolute value < 100. Follows C99
8270 standard. This is a change on Windows, which would use 3 digits.
8271 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8272 so that any alterations it does to the resulting string will be
8273 available in stringlib/formatter.h (for float.__format__).
8274
Eric Smith5a3c1352008-02-19 13:21:56 +00008275- Implemented PEP 3101, Advanced String Formatting. This adds a new
8276 builtin format(); a format() method for str and unicode; a
8277 __format__() method to object, str, unicode, int, long, float, and
8278 datetime; the class string.Formatter; and the C API
8279 PyObject_Format().
8280
Georg Brandl3ee81df2008-05-17 18:14:43 +00008281- Fixed several potential crashes, all caused by specially crafted
8282 __del__ methods exploiting objects in temporarily inconsistent
8283 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008284
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008285- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008286 prevent a possible crash: an Abstract Base Class would try to access
8287 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008288
Georg Brandl3ee81df2008-05-17 18:14:43 +00008289- Fixed repr() and str() of complex numbers with infinity or nan as
8290 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00008291
Georg Brandl3ee81df2008-05-17 18:14:43 +00008292- Clear all free lists during a gc.collect() of the highest generation
8293 in order to allow pymalloc to free more arenas. Python may give back
8294 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008295
Georg Brandl3ee81df2008-05-17 18:14:43 +00008296- Issue #2045: Fix an infinite recursion triggered when printing a
8297 subclass of collections.defaultdict, if its default_factory is set
8298 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008299
Christian Heimesf75dbef2008-02-08 00:11:31 +00008300- Fixed a minor memory leak in dictobject.c. The content of the free
8301 list was not freed on interpreter shutdown.
8302
Georg Brandl21e99f42010-03-07 15:23:59 +00008303- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008304 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008305
Georg Brandl3ee81df2008-05-17 18:14:43 +00008306- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8307 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008308 to compact the internal free lists of pre-allocted ints and floats.
8309
Georg Brandl3ee81df2008-05-17 18:14:43 +00008310- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8311 calls. Python expected the return type int but the fork familie
8312 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008313
Georg Brandl3ee81df2008-05-17 18:14:43 +00008314- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8315 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008316
Georg Brandl3ee81df2008-05-17 18:14:43 +00008317- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8318 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00008319
Georg Brandl3ee81df2008-05-17 18:14:43 +00008320- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8321 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00008322
Georg Brandl3ee81df2008-05-17 18:14:43 +00008323- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8324 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008325
Georg Brandl3ee81df2008-05-17 18:14:43 +00008326- Patch #1473257: generator objects gain a gi_code attribute. This is
8327 the same object as the func_code attribute of the function that
8328 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008329
Georg Brandl3ee81df2008-05-17 18:14:43 +00008330- Issue #1920: "while 0" statements were completely removed by the
8331 compiler, even in the presence of an "else" clause, which is
8332 supposed to be run when the condition is false. Now the compiler
8333 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008334
Guido van Rossumeead05f2008-01-24 18:21:02 +00008335- A few crashers fixed: weakref_in_del.py (issue #1377858);
8336 loosing_dict_ref.py (issue #1303614, test67.py);
8337 borrowed_ref_[34].py (not in tracker).
8338
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008339- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008340 suppressed while an extension is loaded by calling SetErrorMode in
8341 dynload_win.c. The error is still reported properly.
8342
Georg Brandl3ee81df2008-05-17 18:14:43 +00008343- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008344 several extension methods and modules do not work without unicode
8345 support.
8346
Georg Brandl26543b12008-01-21 18:36:51 +00008347- Issue #1882: when compiling code from a string, encoding cookies in the
8348 second line of code were not always recognized correctly.
8349
Georg Brandl14404b62008-01-19 19:27:05 +00008350- Issue #1679: "0x" was taken as a valid integer literal.
8351
Georg Brandl6caad7d2008-01-26 14:19:22 +00008352- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008353 added.
8354
Christian Heimesc94e2b52008-01-14 04:13:37 +00008355- sys.float_info / PyFloat_GetInfo: The floating point information
8356 object was converted from a dict to a specialized structseq object.
8357
Georg Brandl3ee81df2008-05-17 18:14:43 +00008358- Patch #1816: Added sys.flags structseq. It exposes the status of
8359 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008360
Georg Brandl3ee81df2008-05-17 18:14:43 +00008361- Objects/structseq.c: Implemented new structseq representation. The
8362 patch makes structseqs (e.g. the return value of os.stat) more
8363 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008364
Georg Brandl3ee81df2008-05-17 18:14:43 +00008365- Patch #1700288: added a type attribute cache that caches method
8366 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008367
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008368- Bug #1776: __import__() no longer accepts filenames on any platform.
8369 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008370

8372
Georg Brandl3ee81df2008-05-17 18:14:43 +00008373- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8374 envvar and sys.dont_write_bytecode attribute. All these can be set
8375 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008376
Georg Brandl3ee81df2008-05-17 18:14:43 +00008377- Improve some exception messages when Windows fails to load an
8378 extension module. Now we get for example '%1 is not a valid Win32
8379 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008380
Georg Brandl3ee81df2008-05-17 18:14:43 +00008381- Bug #1481296: Fixed long(float('nan')) != 0L.

8384 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008385
Christian Heimes0a8143f2007-12-18 23:22:54 +00008386- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008387 and INF. float("nan"), float("inf") and float("-inf") now work on
8388 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008389
Georg Brandl3ee81df2008-05-17 18:14:43 +00008390- Compiler now generates simpler and faster code for dictionary
8391 literals. The oparg for BUILD_MAP now indicates an estimated
8392 dictionary size. There is a new opcode, STORE_MAP, for adding
8393 entries to the dictionary.

8425 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008426
Georg Brandl3ee81df2008-05-17 18:14:43 +00008427- Issue #1265: Fix a problem with sys.settrace, if the tracing
8428 function uses a generator expression when at the same time the
8429 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008430
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008431- sets and frozensets now have an isdisjoint() method.
8432

8436
Georg Brandl21e99f42010-03-07 15:23:59 +00008437- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008438 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8439 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008440
Georg Brandl3ee81df2008-05-17 18:14:43 +00008441- Issue #1686386: Tuple's tp_repr did not take into account the
8442 possibility of having a self-referential tuple, which is possible
8443 from C code. Nor did object's tp_str consider that a type's tp_str
8444 could do something that could lead to an inifinite recursion.
8445 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8446 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008447
Georg Brandl3ee81df2008-05-17 18:14:43 +00008448- Issue #1164: It was possible to trigger deadlock when using the
8449 'print' statement to write to a file since the GIL was not released
8450 as needed. Now PyObject_Print() does the right thing along with
8451 various tp_print implementations of the built-in types and those in
8452 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008454- Issue #1147: Exceptions were directly allowing string exceptions in
8455 their throw() method even though string exceptions no longer
8456 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +00008461- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008462 PyObject_Call() never calling back out to Python code to trigger
8463 recursion depth updates/checks. Required the creation of a static
8464 RuntimeError instance in case normalizing an exception put the
8465 recursion check value past its limit. Fixes crashers
8466 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00008481- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008482 __*__ attributes. (Some already existed, e.g., __doc__ and
8483 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008484
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008485- Add -3 option to the interpreter to warn about features that are

8489 calls.
8490
Collin Winter62903052007-05-18 23:11:24 +00008491- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008492 "except E as target:". This is to provide forwards compatibility
8493 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008494
Brett Cannon229cee22007-05-05 01:34:02 +00008495- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008500- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008501 setting a plain string, ie don't expand to single letter identifiers.
8502
Raymond Hettinger13936692007-04-11 18:40:58 +00008503- Request #1191699: Slices can now be pickled.
8504
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008505- Request #1193128: str.translate() now allows a None argument for
8506 translations that only remove characters without re-mapping the
8507 remaining characters.
8508
Georg Brandl5cb76c12007-03-21 09:00:39 +00008509- Patch #1682205: a TypeError while unpacking an iterable is no longer

8513
Guido van Rossum143b5642007-03-23 04:58:42 +00008514- Bug #1683368: The object.__init__() and object.__new__() methods are
8515 now stricter in rejecting excess arguments. The only time when
8516 either allows excess arguments is when it is not overridden and the
8517 other one is. For backwards compatibility, when both are
8518 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008519 warning later). Also, type.__init__() insists on the same signature
8520 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008521
Georg Brandl3ee81df2008-05-17 18:14:43 +00008522- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8523 object to complex using its __complex__() method before falling back
8524 to the __float__() method. Therefore, the functions in the cmath
8525 module now can operate on objects that define a __complex__()
8526 method.

8537 its type.

8543
Georg Brandl7b9c5552007-03-12 14:30:05 +00008544- Bug #1678647: write a newline after printing an exception in any
8545 case, even when converting the value to a string failed.
8546
Georg Brandl871f1bc2007-03-12 13:17:36 +00008547- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008548 its argument, if it exists. If not, it will work like before. This
8549 allows customizing the output of dir() in the presence of a
8550 __getattr__().

8559 parthensized forms. This means complex(repr(x)) now works instead of
8560 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008561
Georg Brandlaa2321b2007-03-07 00:40:28 +00008562- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008563 makes the filenames the warning module prints much more sensible
8564 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00008577- Patch #1674228: when assigning a slice (old-style), check for the
8578 sq_ass_slice instead of the sq_slice slot.
8579
Georg Brandl3ee81df2008-05-17 18:14:43 +00008580- When printing an unraisable error, don't print exceptions. before

9190 Python would crash instead of raising an error.
9191

9207 accepted in TestSuite.addTest(). This should cause no
9208 incompatibility since it never made sense with ordinary subclasses
9209 -- the failure just occurred later, with a more cumbersome
9210 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009485- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9486 with RFC 3207 and forgets any knowledge obtained from the server not
9487 obtained from the TLS negotiation itself. Patch contributed by Bill
9488 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009489
Georg Brandl3ee81df2008-05-17 18:14:43 +00009490- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009491 that the SMTP.starttls() caller no longer needs to call ehlo()
9492 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009493 does not claim to support starttls. Adds the
9494 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

9575 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9576 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00009593 time so that opening a database previously created with the DB_DUP
9594 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9595 opens. Specifically: dictionary assignment to a DB object will
9596 replace all values for a given key when the database allows
9597 duplicate values. DB users should use DB.put(k, v) when they want
9598 to store duplicates; not DB[k] = v.

9605 characters with ASCII value less than 32. Also, it correctly quotes
9606 dots only if they occur on a single line, as opposed to the previous
9607 behavior of quoting dots if they are the second character of any
9608 line.

9936-----
9937
Georg Brandl3ee81df2008-05-17 18:14:43 +00009938- Unified naming convention for free lists and their limits. All free
9939 lists in Object/ are named ``free_list``, the counter ``numfree``
9940 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
9941 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009942
Georg Brandl3ee81df2008-05-17 18:14:43 +00009943- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9944 to ``PyTuple_SetItem``, it can be used to populate a brand new
9945 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00009946
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009947- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009949- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
9950 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
9951 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009952
9953- Patch #1720595: add T_BOOL to the range of structmember types.
9954
9955- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9956 ``PyFloat_GetInfo()`` to the float API.
9957
Georg Brandl3ee81df2008-05-17 18:14:43 +00009958- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9959 of w# format code incorrectly truncated the length to an int, even
9960 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9961 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009962
Georg Brandl3ee81df2008-05-17 18:14:43 +00009963- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
9964 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009966- PEP 3123: Provide forward compatibility with Python 3.0, while
9967 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
9968 and PyVarObject_HEAD_INIT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009970- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
9971 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009972
9973- Patch #1733960: Allow T_LONGLONG to accept ints.

9981- Fix some leftovers from the conversion from int to Py_ssize_t
9982 (relevant to strings and sequences of more than 2**31 items).
9983
9984- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9985 outside of pystate.c and should not be necessary.
9986
Georg Brandl3ee81df2008-05-17 18:14:43 +00009987- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9988 absolute imports. In earlier versions they might have used relative
9989 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009990
Georg Brandl3ee81df2008-05-17 18:14:43 +00009991- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9992 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009993
Georg Brandl3ee81df2008-05-17 18:14:43 +00009994- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +000010000- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10001 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10002 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10003 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010004
Georg Brandl3ee81df2008-05-17 18:14:43 +000010005- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +000010017- Removed the macfs module. It had been deprecated since Python 2.5.
10018 This lead to the deprecation of macostools.touched() as it relied
10019 solely on macfs and was a no-op under OS X.
