Ned Deily18fae3f2013-01-31 01:24:55 -0800896- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
897 In particular, fix extension module build failures when trying to use
898 32-bit-only installer Pythons on systems with Xcode 4 (currently
899 OS X 10.8, 10.7, and optionally 10.6).
900 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
901 * Since Xcode 4 removes ppc support, extension module builds now
902 check for ppc compiler support and by default remove ppc and
903 ppc64 archs when they are not available.
904 * Extension module builds now revert to using system installed
905 headers and libs (/usr and /System/Library) if the SDK used
906 to build the interpreter is not installed or has moved.
907 * Try to avoid building extension modules with deprecated
908 and problematic Apple llvm-gcc compiler. If original compiler
909 is not available, use clang instead by default.

1259
Mark Dickinsondbbed042011-09-19 16:38:08 +01001260- Issue #12973: Fix overflow checks that invoked undefined behaviour in
1261 int.__pow__. These overflow checks were causing int.__pow__ to produce
1262 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001263 compiler optimizing the check away. Also fix similar overflow checks
1264 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
1265 bugs caused test failures with recent versions of Clang.

Antoine Pitrou16166452011-07-12 22:04:20 +02001276- Issue #12149: Update the method cache after a type's dictionnary gets
1277 cleared by the garbage collector. This fixes a segfault when an instance
1278 and its type get caught in a reference cycle, and the instance's
1279 deallocator calls one of the methods on the type (e.g. when subclassing
1280 IOBase). Diagnosis and patch by Davide Rizzo.

Florent Xiclunaa1f948b2012-01-24 21:05:10 +01001282- Issue #12501: Remove Py3k warning for callable. callable() is supported

Victor Stinner08563d92011-05-30 23:44:13 +02001289 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
1290 raw_input() interrupted by CTRL+c.

Florent Xiclunac2279652012-02-12 14:49:03 +01001333- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001334 has left two versions of customize_compiler, the original in
1335 distutils.sysconfig and another copy in distutils.ccompiler, with some
1336 parts of distutils calling one and others using the other.

1338 is the case in 3.x.
1339
Ned Deily0d0ea482012-02-10 12:59:06 +01001340- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1341 Distutils-based packages with C extension modules may fail because
1342 Apple has removed gcc-4.2, the version used to build python.org
1343 64-bit/32-bit Pythons. If the user does not explicitly override
1344 the default C compiler by setting the CC environment variable,
1345 Distutils will now attempt to compile extension modules with clang
1346 if gcc-4.2 is required but not found. Also as a convenience, if
1347 the user does explicitly set CC, substitute its value as the default
1348 compiler in the Distutils LDSHARED configuration variable for OS X.
1349 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1350 SDK, neither of which are available in Xcode 4. This change does not
1351 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001601- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1602 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1603 interpreter process. This could cause failures in non-Distutils subprocesses
1604 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001605 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001606 deployment target only in the environment of each build subprocess. It is
1607 still possible to globally override the default by setting
1608 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1609 greater or equal to the default value, the value with which the interpreter
1610 was built.

1639 updating the check interval, so if the user decreases the check interval,
1640 the ticker doesn't have to wind down to zero from the old starting point
1641 before the new interval takes effect. And if the user increases the
1642 interval, it makes sure the new limit takes effect right away rather have an
1643 early task switch before recognizing the new interval.

2625 becoming permanently uncollectable GC garbage. The downside is that
2626 removing __del__ means that the internal doubly-linked list has to wait for
2627 GC collection rather than freeing memory immediately when the refcnt drops

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003087- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3088 start byte and the continuation byte(s) are now considered invalid, instead
3089 of the number of bytes specified by the start byte.
3090 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3091 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3092 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

3102 objects. (1) The comparison could incorrectly return True in some cases
3103 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3104 (2) The comparison raised an OverflowError for large integers, leading

3300 operation raises multiple signals and more than one of those signals is
3301 trapped, the specification determines the order in which the signals should be

Georg Brandlfee0f442010-05-22 21:26:21 +00003447- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00003448 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
3449 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
3450 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

3470Core and Builtins
3471-----------------
3472
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003473- Issue #7301: Add environment variable $PYTHONWARNINGS.
3474
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003475- Issue #8329: Don't return the same lists from select.select when no fds are
3476 changed.
3477
Georg Brandlfee0f442010-05-22 21:26:21 +00003478- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003479 on 64-bit machines. The shift count for either left or right shift is
3480 permitted to be up to sys.maxsize.
3481
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003482- Ensure that tokenization of identifiers is not affected by locale.
3483
Georg Brandlfee0f442010-05-22 21:26:21 +00003484- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00003485
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00003486- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
3487
Georg Brandlfee0f442010-05-22 21:26:21 +00003488- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3489 with a non-empty format string. This is an effort to future-proof user
3490 code. If a derived class does not currently implement __format__ but later
3491 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003492 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003493 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003494
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003495- Issue #8268: Old-style classes (not just instances) now support weak
3496 references.
3497
Georg Brandlfee0f442010-05-22 21:26:21 +00003498- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
3499 is set.

3507
Victor Stinner66644262010-03-10 22:30:19 +00003508- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003509 (SIGINT). If an error occurs while importing the site module, the error is
3510 printed and Python exits. Initialize the GIL before importing the site

Antoine Pitrouf9de5342010-04-05 21:35:07 +00003520- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00003521 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and

Benjamin Peterson76a23c12010-04-04 23:23:22 +00003524- Issue #8310: Allow dis to examine new style classes.
3525
Georg Brandlfee0f442010-05-22 21:26:21 +00003526- Issue #8257: The Decimal construct now accepts a float instance directly,
3527 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003528
3529 >>> Decimal(1.1)
3530 Decimal('1.100000000000000088817841970012523233890533447265625')
3531
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003532- collections.Counter() now supports a subtract() method.
3533
Georg Brandlfee0f442010-05-22 21:26:21 +00003534- The functools module now has a total_ordering() class decorator to simplify
3535 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00003536
Georg Brandlfee0f442010-05-22 21:26:21 +00003537- The functools module also adds cmp_to_key() as a tool to transition old-style
3538 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00003539
Georg Brandlfee0f442010-05-22 21:26:21 +00003540- Issue #8294: The Fraction constructor now accepts Decimal and float instances
3541 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00003542
Georg Brandlfee0f442010-05-22 21:26:21 +00003543- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3544 InvalidOperation instead of returning False. (Comparisons involving a quiet
3545 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3546 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003547
Georg Brandlfee0f442010-05-22 21:26:21 +00003548- Issue #2531: Comparison operations between floats and Decimal instances now
3549 return a result based on the numeric values of the operands; previously they
3550 returned an arbitrary result based on the relative ordering of id(float) and
3551 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003552
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003553- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003554 argument `-` which tells it to read files to compile from stdin. Each line is
3555 read on demand and the named file is compiled immediately. (Original patch by
3556 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003557
Georg Brandlfee0f442010-05-22 21:26:21 +00003558- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
3559 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00003561- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3562 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003563 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003564
Georg Brandlfee0f442010-05-22 21:26:21 +00003565- Comparisons using one of <, <=, >, >= between a complex instance and a
3566 Fractions instance now raise TypeError instead of returning True/False. This
3567 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3568 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00003569
Michael Foorde6410c52010-03-29 20:04:23 +00003570- Addition of ``WeakSet`` to the ``weakref`` module.

Florent Xicluna9e7a4c92010-03-22 16:07:38 +00003583- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
3584 deprecated.
3585
Georg Brandlfee0f442010-05-22 21:26:21 +00003586- Issue #7860: platform.uname now reports the correct 'machine' type when Python

Vinay Sajipecfa08f2010-03-12 09:16:10 +00003623- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00003624 for ``TimedRotatingFileHandler`` by using the modification time of an existing
3625 log file to compute the next rollover time. If the log file does not exist,
3626 the current time is used as the basis for the computation.

3637 a base64 transfer-encoded payload *after* decoding it; it no longer does.
3638 This is a behavior change, so email's minor version number is now bumped, to

3668 integer format code, struct.pack first attempts to convert the non-integer

3670 TypeError it goes on to try the __int__ method, as described below.
3671
Georg Brandlba83f822010-03-14 09:50:54 +00003672- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
3673 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3674 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003675 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3676 inconsistent: __int__ was used for some integer codes but not for others, and
3677 the set of integer codes for which it was used differed between native packing

3910 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00003911 library would return a bogus result; on Solaris, it was possible to crash the

Georg Brandlba83f822010-03-14 09:50:54 +00003930- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
3931 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3932 returning NULL. The macro now returns a statically allocated empty string
3933 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00003986 file position when calling `truncate()`. It would previously change the file
3987 position to the given argument, which goes against the tradition of

3991 class used to represent files stored inside an archive. The new
3992 implementation is significantly faster and can be wrapped in a
3993 ``io.BufferedReader`` object for more speedups. It also solves an issue
3994 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

4007 encoded string for them. This ensures that the upload and register commands
4008 send the correct values to PyPI without any error.

4084
Georg Brandlba83f822010-03-14 09:50:54 +00004085- The ``__complex__()`` method is now looked up on the class of instances to
4086 make it consistent with other special methods.

4090
Mark Dickinson1b34d252010-01-01 17:27:30 +00004091- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004092 DeprecationWarning when passed a float argument where an integer was expected.
4093 These functions and methods now raise TypeError instead. The majority of the
4094 effects of this change are in the extension modules, but some core functions
4095 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4096 and many unicode/str methods.

4110 of integers: the result of a/b is now correctly rounded for ints a and b (at
4111 least on IEEE 754 platforms), and in particular does not depend on the
4112 internal representation of a long.

4120
Georg Brandlba83f822010-03-14 09:50:54 +00004121 These executables now work properly with the arch(1) command: ``arch -ppc
4122 python`` will start a universal binary version of python in PPC mode (unlike

4263 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004264
Georg Brandlba83f822010-03-14 09:50:54 +00004265- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4266 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00004267

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00004278
Georg Brandlba83f822010-03-14 09:50:54 +00004279- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4280 decimal string that's guaranteed to round back to x under correct rounding
4281 (with round-half-to-even rounding mode). Previously it gave a string based on
4282 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4283 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4284 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004285
Georg Brandlba83f822010-03-14 09:50:54 +00004286- Issue #7117: On almost all platforms: float-to-string and string-to-float
4287 conversions within Python are now correctly rounded. Places these conversions
4288 occur include: str for floats and complex numbers; the float and complex
4289 constructors; old-style and new-style numeric formatting; serialization and
4290 deserialization of floats and complex numbers using marshal, pickle and json;
4291 parsing of float and imaginary literals in Python code; Decimal-to-float
4292 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004293
Georg Brandlba83f822010-03-14 09:50:54 +00004294 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4295 providing correctly-rounded strtod and dtoa C functions. This code is
4296 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4297 the C compiler. There may be a small number of platforms on which correct
4298 operation of this code cannot be guaranteed, so the code is not used: notably,
4299 this applies to platforms where the C double format is not IEEE 754 binary64,
4300 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4301 and Python's configure script is unable to determine how to change the FPU
4302 precision. On these platforms conversions use the platform strtod and dtoa,
4303 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004305- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4306 uses the correctly-rounded string <-> float conversions described above (when
4307 available), and so produces correctly rounded results that will display nicely
4308 under the float repr. There are two related small changes: (1) round now
4309 accepts any class with an ``__index__()`` method for its second argument (but
4310 no longer accepts floats for the second argument), and (2) an excessively
4311 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4312 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00004454
Georg Brandlba83f822010-03-14 09:50:54 +00004455 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4456 (2) parsing of strings representing infinities and nans was locale aware; and
4457 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004459- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4460 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4461 but with at least one decimal point and with a default precision
4462 of 12. Previously, the behavior the same but with a default precision of 6.
4463 This more closely matches ``str()``, and reduces surprises when adding
4464 alignment flags to the empty presentation type. This also affects the new
4465 complex.__format__ in the same way.
4466
4467- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
4468 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00004530 untrackable objects are not tracked by the garbage collector. This can reduce

4539 internal representation of integers, for performance reasons. Base 2**30 is
4540 enabled by default on 64-bit machines. Add --enable-big-digits option to

4627
Georg Brandl6425a2f2008-12-28 11:54:53 +00004628- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00004629 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00004630
Skip Montanarof205c132008-12-23 03:30:15 +00004631- Added test case to ensure attempts to read from a file opened for writing
4632 fail.
4633
Georg Brandlba83f822010-03-14 09:50:54 +00004634- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
4635 elapsed times, not only when some objects are uncollectable/unreachable.

Georg Brandlba83f822010-03-14 09:50:54 +00004648- Issue #4445: Replace ``sizeof(PyStringObject)`` with
4649 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
4650 instances. On a typical machine this saves 3 bytes of memory (on average) per
4651 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00004653- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
4654 interpreter to abort ("Fatal Python error: Could not reset the stack!")
4655 instead of throwing a MemoryError.
4656
Georg Brandlba83f822010-03-14 09:50:54 +00004657- Issue #3689: The list reversed iterator now supports __length_hint__ instead

Benjamin Petersonc078f922008-11-21 22:27:24 +00004660- Issue #4367: Python would segfault during compiling when the unicodedata

4662
Georg Brandlba83f822010-03-14 09:50:54 +00004663- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4664 file objects with closefd=False. The file descriptor is still kept open but
4665 the file object behaves like a closed file. The ``FileIO`` object also got a
4666 new readonly attribute ``closefd``.

Benjamin Peterson46cc6d12008-11-19 21:49:09 +00004668- Issue #4348: Some bytearray methods returned that didn't cause any change to
4669 the bytearray, returned the same bytearray instead of a copy.
4670
Georg Brandlba83f822010-03-14 09:50:54 +00004671- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Petersonbdca9422008-10-26 20:21:13 +00004683- Issue #4209: Enabling unicode_literals and the print_function in the same
4684 __future__ import didn't work.
4685
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004686- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00004687 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004688
Georg Brandlba83f822010-03-14 09:50:54 +00004689- On windows, ``os.chdir()`` given unicode was not working if
4690 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4691 this code path is really executed because I cannot move to such directory on
4692 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00004693
Georg Brandlba83f822010-03-14 09:50:54 +00004694- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4695 element is temporarily replaced with an equivalent frozenset. But the
4696 eventual KeyError would always report the empty ``frozenset()`` as the missing
4697 key. Now it correctly refers to the initial element.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +00004714- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
4715 returned them on 64bit platforms.
4716
Walter Dörwalded960ac2009-05-03 22:36:33 +00004717- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4718 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4719 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4720 of using the replace error handler in PyUnicode_DecodeUTF8().
4721
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004722- Issue #3739: The unicode-internal encoder now reports the number of characters
4723 consumed like any other encoder (instead of the number of bytes).
4724
Georg Brandlba83f822010-03-14 09:50:54 +00004725- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4726 allocator will be automatically disabled when running under Valgrind. This
4727 gives improved memory leak detection when running under Valgrind, while taking
4728 advantage of pymalloc at other times.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00005973- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
5974 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00005975 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
5976 the tests if DISPLAY is defined but can't be used.

Georg Brandlba83f822010-03-14 09:50:54 +00005981- Issue #5354: New test support function import_fresh_module() makes it easy to
5982 import both normal and optimised versions of modules. test_heapq and
5983 test_warnings have been adjusted to use it, tests for other modules with both
5984 C and Python implementations in the stdlib can be adjusted to use it over
5985 time.

Georg Brandlba83f822010-03-14 09:50:54 +00005993- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
5994 should cause a test to be skipped are now done using import_module from test
5995 support, which does the conversion.

6097
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006098- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6099 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6100 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6101 ``printf`` function, whereas PyString_FromFormat has an independent
6102 implementation and uses "%zd" on all platforms for size_t values.
6103 This makes a difference on win64, where ``printf`` needs "%Id" to display
6104 64bit values.

6110 object; previously an int would be returned for small values. the __long__
6111 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006121 was correctly parsed but parsing of subsequent arguments failed.
6122
Vinay Sajip35e3b032008-09-01 14:33:59 +00006123- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006124 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6125 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6126 when given a tuple of classes as second argument, were looking up
6127 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6128 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006267What's New in Python 2.6 beta 3?
6268================================
6269
Barry Warsaw07a4a382008-08-21 01:15:08 +00006270*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006271
6272Core and Builtins
6273-----------------
6274
Guido van Rossumf8402962008-08-20 15:01:50 +00006275- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6276 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6277 extensions do not automatically benefit from the class attribute
6278 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6279 to their tp_flags field if they care. This is a backwards
6280 compatibility feature; in 3.0, all types will use the cache by
6281 default.
6282
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006283- Keyword arguments can now follow starred arguments. (``f(a, *args,
6284 keyword=23)`` is now valid syntax.)
6285
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006286- ctypes function pointers that are COM methods have a boolean True
6287 value again.
6288
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006289- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6290 by denying s# to parse objects that have a releasebuffer procedure,
6291 and introducing s*.
6292
Georg Brandl1e13ea92008-08-11 09:07:59 +00006293- Issue #3537: Fix an assertion failure when an empty but presized dict
6294 object was stored in the freelist.
6295
Mark Dickinsonb6467572008-08-04 21:30:09 +00006296- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6297 ValueError consistently across platforms.
6298
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006299- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6300 (64bit Unix, for example), unichr() would truncate its argument and return
6301 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6302
Neal Norwitze7d8be82008-07-31 17:17:14 +00006303- Apply security patches from Apple.
6304
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006305- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6306 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6307
Antoine Pitrou92f82162008-07-25 22:22:08 +00006308- Issue #1819: function calls with several named parameters are now on
6309 average 35% faster (as measured by pybench).
6310
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006311- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6312 the python debugger steps into a class statement: the free variables (local
6313 variables defined in an outer scope) would be deleted from the outer scope.
6314
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006315- Issue #2620: Overflow checking when allocating or reallocating memory
6316 was not always being done properly in some python types and extension
6317 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6318 all been updated to perform better checks and places in the code that
6319 would previously leak memory on the error path when such an allocation
6320 failed have been fixed.
6321
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006322Library
6323-------
6324
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006325- Issue #3612: Added some missing basic types in ctypes.wintypes.
6326
Benjamin Petersone977ad42008-08-20 01:42:01 +00006327- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6328 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6329
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006330- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6331 version reported by these tools does not necessarily follow the python
6332 version numbering scheme, so the module is less strict when parsing it.
6333
Nick Coghlanf70385a2008-08-18 12:42:46 +00006334- Issue #2235: Added Py3k warnings for types which will become unhashable
6335 under the stricter __hash__ inheritance rules in 3.0. Several types
6336 which did not meet the rules for hash invariants and were already
6337 unhashable in 3.0 have now been explicitly flagged as unhashable in
6338 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6339 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6340
Brett Cannon88f801d2008-08-18 00:46:22 +00006341- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6342 imported into the module but exposed as part of the module's API.
6343
Brett Cannon7b96f072008-08-18 00:41:11 +00006344- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6345
Brett Cannon46225e72008-08-18 00:36:52 +00006346- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
6347
Brett Cannon25c9d6a2008-08-17 22:10:11 +00006348- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6349
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006350- Issue #3575: Incremental decoder's decode function now takes bytearray
6351 by using 's*' instead of 't#'.
6352
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006353- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006354 fails unicode conversion on 2nd parameter. (windows only)
6355
Georg Brandl222e2082010-08-01 22:27:39 +00006356- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006357 in a redirect.
6358
Brett Cannonabe423e2008-08-16 21:47:07 +00006359- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006360 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006361
Facundo Batistaeb90b782008-08-16 14:44:07 +00006362- Issue #2776: fixed small issue when handling an URL with double slash
6363 after a 302 response in the case of not going through a proxy.
6364
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006365- Issue #2676: in the email package, content-type parsing was hanging on
6366 pathological input because of quadratic or exponential behaviour of a
6367 regular expression.
6368
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006369- Issue #3476: binary buffered reading through the new "io" library is now
6370 thread-safe.
6371
Brett Cannonbf3157b2008-08-14 05:00:03 +00006372- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6373 since mimetools itself is deprecated. Because modules are cached, all
6374 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6375
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006376- Issue #3134: shutil referenced undefined WindowsError symbol.
6377
Robert Schuppenies14646332008-08-10 11:01:53 +00006378- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6379 menu entries were not deleted.
6380
Brett Cannon83e81842008-08-09 23:30:55 +00006381- Copied the implementation of reduce() to _functools.reduce() to have a
6382 version that did not raise a DeprecationWarning under -3.
6383
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006384- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6385 a MemoryError rather than silently stop the iteration.
6386
Guido van Rossum59ce9012008-08-09 14:55:34 +00006387- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6388 to _sre.compile() will now be rejected. This should not affect anybody
6389 since the re.compile() function never generates invalid re-bytecode.
6390
Skip Montanaroa032bf42008-08-08 22:52:51 +00006391- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6392 upon first access it can be automatically initialized from the csv file if
6393 it wasn't initialized during instantiation.
6394
Brett Cannon3aa2a492008-08-06 22:28:09 +00006395- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6396 the reload() built-in has been removed.
6397
Brett Cannon7e30b672008-08-04 21:52:25 +00006398- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006399 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00006400 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
6401 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
6402 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
6403 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
6404 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00006405
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00006406- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
6407 raised an AttributeError.
6408
Benjamin Peterson01a24322008-07-28 23:35:27 +00006409- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00006410 asking for a specific length. This problem only affected files opened
6411 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006412
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00006413- Issue #3449: Update decimal module to use most recent specification
6414 (v. 1.68) and tests (v. 2.58) from IBM.
6415
Georg Brandl222e2082010-08-01 22:27:39 +00006416- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00006417

Raymond Hettinger8c664e82008-07-25 18:43:33 +00006419 on a closed shelf.
6420
Georg Brandlf9efabb2008-07-23 15:16:45 +00006421- Deprecate the "ast" parser function aliases.
6422
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006423- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
6424
6425- Issue #3303: Fix a crash in locale.strcoll() when calling it with
6426 invalid arguments.
6427
6428- Issue #3302: Fix several crashes when calling locale's gettext functions
6429 with None arguments.
6430
6431- Issue #3389: Allow resolving dotted names for handlers in logging
6432 configuration files.
6433
6434- Deprecate the sunaudio module for removal in Python 3.0.
6435
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006436- Issue #3394: zipfile.writestr sets external attributes when passed a
6437 file name rather than a ZipInfo instance, so files are extracted with
6438 mode 0600 rather than 000 under Unix.
6439
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006440- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6441 argument in python 2.5, this broke code that subclassed Popen to include its
6442 own poll method. Fixed my moving _deadstate to an _internal_poll method.

6450-------------
6451
Nick Coghlan6e8fef02008-08-18 13:14:22 +00006452- Issue #2235: the C API function PyObject_HashNotImplemented and its
6453 interaction with the tp_hash slot (added in 2.6b2) are now documented
6454
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006455- Issue #643841: The language reference now provides more detailed
6456 coverage of the lookup process for special methods. The disclaimers
6457 regarding lack of coverage of new-style classes have also been
6458 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006461What's New in Python 2.6 beta 2?
6462================================
6463
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006464*Release date: 17-Jul-2008*
6465
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006466Core and Builtins
6467-----------------
6468
Georg Brandl3e483f62008-07-16 22:57:41 +00006469- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6470 its methods now allow for items objects that can be converted to
6471 an integer using operator.index().
6472
Mark Dickinson64b7e502008-07-16 09:40:03 +00006473- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6474 produced a ValueError instead of giving the correct float.
6475
Eric Smitha5fa5a22008-07-16 00:11:49 +00006476- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6477 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6478
Mark Dickinson7103aa42008-07-15 19:08:33 +00006479- Issue #3008: the float type has a new instance method 'float.hex'
6480 and a new class method 'float.fromhex' to convert floating-point
6481 numbers to and from hexadecimal strings, respectively.
6482
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006483- Issue #2235: __hash__ is once again inherited by default. To allow
6484 collections.Hashable to remain meaningful in the presence of the
6485 default hash implementation (object.__hash__), it is now possible
6486 to explicit block inheritance of hash by setting __hash__=None at
6487 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6488 level.
6489
Nick Coghlanb028f502008-07-13 14:52:36 +00006490- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6491 the parent module cannot be found while performing an absolute import.
6492 This means that an incorrectly defined __package__ attribute will
6493 now only prevent relative imports in that module rather than causing
6494 all imports from that module to fail.
6495
Nick Coghlan14ff9942008-07-08 14:21:42 +00006496- Issue #2517: Allow unicode messages in Exceptions again by correctly
6497 bypassing the instance dictionary when looking up __unicode__ on
6498 new-style classes.
6499
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006500- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6501 set to a custom object whose write() method happens to install
6502 another file in sys.stdout.
6503
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006504- Issue #3088: Corrected a race condition in classes derived from
6505 threading.local: the first member set by a thread could be saved in
6506 another thread's dictionary.
6507
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006508- Issue #3004: Minor change to slice.indices(): the start and stop
6509 arguments are now treated identically, making the behaviour easier
6510 to describe and understand. For example, slice(None, -10,
6511 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6512 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6513 10, -1).
6514
Georg Brandl278fc502008-07-19 12:46:12 +00006515- Issue #3219: Calling a function with repeated keyword arguments,
6516 f(a=2, a=23), would not cause a syntax error. This was a regression
6517 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006518
Georg Brandl278fc502008-07-19 12:46:12 +00006519- Issue #2862: Make int and float freelist management consistent with
6520 other freelists. Changes their CompactFreeList apis into
6521 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00006522

6525
Thomas Heller57adf222008-08-14 19:10:48 +00006526- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6527 api functions without holding the GIL, which could lead to a fatal
6528 error when they failed.
6529
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006530- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00006538- Issue #3125: Remove copy_reg in multiprocessing and replace it with
6539 ForkingPickler.register() to resolve conflict with ctypes.
6540
Vinay Sajip51e65192008-07-18 09:01:10 +00006541- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

6544 a valid dlerror() message.
6545
Thomas Heller2bad6572008-07-15 17:19:50 +00006546- Issue #3258: Fixed a crash when a ctypes POINTER type to an
6547 incomplete structure was created.
6548
Brett Cannon3d0b9f02008-07-13 01:15:07 +00006549- Issue #3339: dummy_thread.acquire() should not return None.

6966 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006967 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006968
6969 This is controlled by the configure argument ``--with-universal-archs``:
6970
6971 - ``--with-universal-archs=all``: install 4-way universal
6972
6973 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6974
6975 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6976
6977 This option should be used in combination with ``--enable-universalsdk=``.
6978
6979 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

7016 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00007017
Christian Heimese74c8f22008-04-19 02:23:57 +00007018- Added kill, terminate and send_signal(sig) to subprocess.Popen.
7019
Georg Brandl3ee81df2008-05-17 18:14:43 +00007020- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
7021 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00007022

Georg Brandl3ee81df2008-05-17 18:14:43 +00007029- Issue #1631171: Re-implement the 'warnings' module in C (the
7030 original Python code has been kept as backup). This will allow for
7031 using the 'warning's machinery in such places as the parser where
7032 use of pure Python code is not possible. Both the ``showarning()``
7033 and ``formatwarning()`` gain an optional 'line' argument which is
7034 not called by default for backwards-compatibility reasons. Setting
7035 ``warnings.showwarning()`` to an implementation that lacks support
7036 for the ``line`` argument will raise a DeprecationWarning.

7060
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007061- The getpass module has been improved on Unix. It now uses /dev/tty
7062 by default and uses stderr instead of stdout. A GetPassWarning is
7063 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00007064

Georg Brandl3ee81df2008-05-17 18:14:43 +00007078- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007079 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00007099- Issue #2550: The approach used by client/server code for obtaining
7100 ports to listen on in network-oriented tests has been refined in an
7101 effort to facilitate running multiple instances of the entire
7102 regression test suite in parallel without issue.
7103 test_support.bind_port() has been fixed such that it will always
7104 return a unique port -- which wasn't always the case with the
7105 previous implementation, especially if socket options had been set
7106 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7107 new implementation of bind_port() will actually raise an exception
7108 if it is passed an AF_INET/SOCK_STREAM socket with either the
7109 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7110 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7111 the socket it's been passed. This currently only applies to
7112 Windows. This option prevents any other sockets from binding to the
7113 host/port we've bound to, thus removing the possibility of the
7114 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7115 when a second SOCK_STREAM socket binds and accepts to a host/port
7116 that's already been bound by another socket. The optional preferred
7117 port parameter to bind_port() has been removed. Under no
7118 circumstances should tests be hard coding ports!
7119
7120 test_support.find_unused_port() has also been introduced, which will
7121 pass a temporary socket object to bind_port() in order to obtain an
7122 unused port. The temporary socket object is then closed and
7123 deleted, and the port is returned. This method should only be used
7124 for obtaining an unused port in order to pass to an external program
7125 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7126 a parameter to a server-oriented class that doesn't give you direct
7127 access to the underlying socket used.
7128
7129 Finally, test_support.HOST has been introduced, which should be used
7130 for the host argument of any relevant socket calls (i.e. bind and
7131 connect).

7139 suite to run in parallel without issue.

7407
Fred Drakea8ee94b2008-03-01 02:45:07 +00007408- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007409 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00007410
Georg Brandlad61bc82008-02-23 15:11:18 +00007411- Issue #2067: file.__exit__() now calls subclasses' close() method.
7412
7413- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00007414
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007415- Issue #1881: An internal parser limit has been increased. Also see

Facundo Batistafc2d0102008-02-23 12:01:13 +00007417
Eric Smitha73fbe72008-02-23 03:09:44 +00007418- Added the future_builtins module, which contains hex() and oct().
7419 These are the PEP 3127 version of these functions, designed to be
7420 compatible with the hex() and oct() builtins from Python 3.0. They
7421 differ slightly in their output formats from the existing, unchanged
7422 Python 2.6 builtins. The expected usage of the future_builtins
7423 module is:
7424 from future_builtins import hex, oct
7425
Eric Smith7ef40bf2008-02-20 23:34:22 +00007426- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7427 exponents for exponents with absolute value < 100. Follows C99
7428 standard. This is a change on Windows, which would use 3 digits.
7429 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7430 so that any alterations it does to the resulting string will be
7431 available in stringlib/formatter.h (for float.__format__).
7432
Eric Smith5a3c1352008-02-19 13:21:56 +00007433- Implemented PEP 3101, Advanced String Formatting. This adds a new
7434 builtin format(); a format() method for str and unicode; a
7435 __format__() method to object, str, unicode, int, long, float, and
7436 datetime; the class string.Formatter; and the C API
7437 PyObject_Format().
7438
Georg Brandl3ee81df2008-05-17 18:14:43 +00007439- Fixed several potential crashes, all caused by specially crafted
7440 __del__ methods exploiting objects in temporarily inconsistent
7441 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007442
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007443- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007444 prevent a possible crash: an Abstract Base Class would try to access
7445 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007446
Georg Brandl3ee81df2008-05-17 18:14:43 +00007447- Fixed repr() and str() of complex numbers with infinity or nan as
7448 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00007449
Georg Brandl3ee81df2008-05-17 18:14:43 +00007450- Clear all free lists during a gc.collect() of the highest generation
7451 in order to allow pymalloc to free more arenas. Python may give back
7452 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007453
Georg Brandl3ee81df2008-05-17 18:14:43 +00007454- Issue #2045: Fix an infinite recursion triggered when printing a
7455 subclass of collections.defaultdict, if its default_factory is set
7456 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007457
Christian Heimesf75dbef2008-02-08 00:11:31 +00007458- Fixed a minor memory leak in dictobject.c. The content of the free
7459 list was not freed on interpreter shutdown.
7460
Georg Brandl21e99f42010-03-07 15:23:59 +00007461- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007462 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007463
Georg Brandl3ee81df2008-05-17 18:14:43 +00007464- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7465 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007466 to compact the internal free lists of pre-allocted ints and floats.
7467
Georg Brandl3ee81df2008-05-17 18:14:43 +00007468- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7469 calls. Python expected the return type int but the fork familie
7470 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007471
Georg Brandl3ee81df2008-05-17 18:14:43 +00007472- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7473 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007474
Georg Brandl3ee81df2008-05-17 18:14:43 +00007475- Issue #2025: Add tuple.count() and tuple.index() methods to comply
7476 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00007477

Georg Brandl3ee81df2008-05-17 18:14:43 +00007481- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7482 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007483
Georg Brandl3ee81df2008-05-17 18:14:43 +00007484- Patch #1473257: generator objects gain a gi_code attribute. This is
7485 the same object as the func_code attribute of the function that
7486 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007487
Georg Brandl3ee81df2008-05-17 18:14:43 +00007488- Issue #1920: "while 0" statements were completely removed by the
7489 compiler, even in the presence of an "else" clause, which is
7490 supposed to be run when the condition is false. Now the compiler
7491 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007492
Guido van Rossumeead05f2008-01-24 18:21:02 +00007493- A few crashers fixed: weakref_in_del.py (issue #1377858);
7494 loosing_dict_ref.py (issue #1303614, test67.py);
7495 borrowed_ref_[34].py (not in tracker).
7496
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007497- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007498 suppressed while an extension is loaded by calling SetErrorMode in
7499 dynload_win.c. The error is still reported properly.
7500
Georg Brandl3ee81df2008-05-17 18:14:43 +00007501- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007502 several extension methods and modules do not work without unicode
7503 support.
7504
Georg Brandl26543b12008-01-21 18:36:51 +00007505- Issue #1882: when compiling code from a string, encoding cookies in the
7506 second line of code were not always recognized correctly.
7507
Georg Brandl14404b62008-01-19 19:27:05 +00007508- Issue #1679: "0x" was taken as a valid integer literal.
7509
Georg Brandl6caad7d2008-01-26 14:19:22 +00007510- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007511 added.
7512
Christian Heimesc94e2b52008-01-14 04:13:37 +00007513- sys.float_info / PyFloat_GetInfo: The floating point information
7514 object was converted from a dict to a specialized structseq object.
7515
Georg Brandl3ee81df2008-05-17 18:14:43 +00007516- Patch #1816: Added sys.flags structseq. It exposes the status of
7517 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007518
Georg Brandl3ee81df2008-05-17 18:14:43 +00007519- Objects/structseq.c: Implemented new structseq representation. The
7520 patch makes structseqs (e.g. the return value of os.stat) more
7521 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007522
Georg Brandl3ee81df2008-05-17 18:14:43 +00007523- Patch #1700288: added a type attribute cache that caches method
7524 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007525
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007526- Bug #1776: __import__() no longer accepts filenames on any platform.

7530
Georg Brandl3ee81df2008-05-17 18:14:43 +00007531- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7532 envvar and sys.dont_write_bytecode attribute. All these can be set
7533 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007534
Georg Brandl3ee81df2008-05-17 18:14:43 +00007535- Improve some exception messages when Windows fails to load an
7536 extension module. Now we get for example '%1 is not a valid Win32
7537 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007538
Georg Brandl3ee81df2008-05-17 18:14:43 +00007539- Bug #1481296: Fixed long(float('nan')) != 0L.

7542 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007543
Christian Heimes0a8143f2007-12-18 23:22:54 +00007544- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007545 and INF. float("nan"), float("inf") and float("-inf") now work on
7546 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007547
Georg Brandl3ee81df2008-05-17 18:14:43 +00007548- Compiler now generates simpler and faster code for dictionary
7549 literals. The oparg for BUILD_MAP now indicates an estimated
7550 dictionary size. There is a new opcode, STORE_MAP, for adding
7551 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007585- Issue #1265: Fix a problem with sys.settrace, if the tracing
7586 function uses a generator expression when at the same time the
7587 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007588
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007589- sets and frozensets now have an isdisjoint() method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007596 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7597 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007598
Georg Brandl3ee81df2008-05-17 18:14:43 +00007599- Issue #1686386: Tuple's tp_repr did not take into account the
7600 possibility of having a self-referential tuple, which is possible
7601 from C code. Nor did object's tp_str consider that a type's tp_str
7602 could do something that could lead to an inifinite recursion.
7603 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7604 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007605
Georg Brandl3ee81df2008-05-17 18:14:43 +00007606- Issue #1164: It was possible to trigger deadlock when using the
7607 'print' statement to write to a file since the GIL was not released
7608 as needed. Now PyObject_Print() does the right thing along with
7609 various tp_print implementations of the built-in types and those in
7610 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007612- Issue #1147: Exceptions were directly allowing string exceptions in
7613 their throw() method even though string exceptions no longer
7614 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +00007619- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007620 PyObject_Call() never calling back out to Python code to trigger
7621 recursion depth updates/checks. Required the creation of a static
7622 RuntimeError instance in case normalizing an exception put the
7623 recursion check value past its limit. Fixes crashers
7624 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00007639- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007640 __*__ attributes. (Some already existed, e.g., __doc__ and
7641 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007642
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007643- Add -3 option to the interpreter to warn about features that are

7647 calls.
7648
Collin Winter62903052007-05-18 23:11:24 +00007649- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007650 "except E as target:". This is to provide forwards compatibility
7651 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007652
Brett Cannon229cee22007-05-05 01:34:02 +00007653- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007658- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007659 setting a plain string, ie don't expand to single letter identifiers.
7660
Raymond Hettinger13936692007-04-11 18:40:58 +00007661- Request #1191699: Slices can now be pickled.
7662
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007663- Request #1193128: str.translate() now allows a None argument for
7664 translations that only remove characters without re-mapping the
7665 remaining characters.
7666
Georg Brandl5cb76c12007-03-21 09:00:39 +00007667- Patch #1682205: a TypeError while unpacking an iterable is no longer

7671
Guido van Rossum143b5642007-03-23 04:58:42 +00007672- Bug #1683368: The object.__init__() and object.__new__() methods are
7673 now stricter in rejecting excess arguments. The only time when
7674 either allows excess arguments is when it is not overridden and the
7675 other one is. For backwards compatibility, when both are
7676 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007677 warning later). Also, type.__init__() insists on the same signature
7678 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007679
Georg Brandl3ee81df2008-05-17 18:14:43 +00007680- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7681 object to complex using its __complex__() method before falling back
7682 to the __float__() method. Therefore, the functions in the cmath
7683 module now can operate on objects that define a __complex__()
7684 method.

7695 its type.

Georg Brandl7b9c5552007-03-12 14:30:05 +00007702- Bug #1678647: write a newline after printing an exception in any
7703 case, even when converting the value to a string failed.
7704
Georg Brandl871f1bc2007-03-12 13:17:36 +00007705- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007706 its argument, if it exists. If not, it will work like before. This
7707 allows customizing the output of dir() in the presence of a
7708 __getattr__().

7717 parthensized forms. This means complex(repr(x)) now works instead of
7718 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007719
Georg Brandlaa2321b2007-03-07 00:40:28 +00007720- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007721 makes the filenames the warning module prints much more sensible
7722 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00007735- Patch #1674228: when assigning a slice (old-style), check for the
7736 sq_ass_slice instead of the sq_slice slot.
7737
Georg Brandl3ee81df2008-05-17 18:14:43 +00007738- When printing an unraisable error, don't print exceptions. before

8349 Python would crash instead of raising an error.
8350

8366 accepted in TestSuite.addTest(). This should cause no
8367 incompatibility since it never made sense with ordinary subclasses
8368 -- the failure just occurred later, with a more cumbersome
8369 exception.

8647 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008648
Georg Brandl3ee81df2008-05-17 18:14:43 +00008649- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008650 that the SMTP.starttls() caller no longer needs to call ehlo()
8651 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008652 does not claim to support starttls. Adds the
8653 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00008752 time so that opening a database previously created with the DB_DUP
8753 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8754 opens. Specifically: dictionary assignment to a DB object will
8755 replace all values for a given key when the database allows
8756 duplicate values. DB users should use DB.put(k, v) when they want
8757 to store duplicates; not DB[k] = v.

8764 characters with ASCII value less than 32. Also, it correctly quotes
8765 dots only if they occur on a single line, as opposed to the previous
8766 behavior of quoting dots if they are the second character of any
8767 line.

9099-----
9100
Georg Brandl3ee81df2008-05-17 18:14:43 +00009101- Unified naming convention for free lists and their limits. All free
9102 lists in Object/ are named ``free_list``, the counter ``numfree``
9103 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
9104 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009105
Georg Brandl3ee81df2008-05-17 18:14:43 +00009106- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9107 to ``PyTuple_SetItem``, it can be used to populate a brand new
9108 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00009109
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009110- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009112- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
9113 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
9114 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009115
9116- Patch #1720595: add T_BOOL to the range of structmember types.
9117
9118- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9119 ``PyFloat_GetInfo()`` to the float API.
9120
Georg Brandl3ee81df2008-05-17 18:14:43 +00009121- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9122 of w# format code incorrectly truncated the length to an int, even
9123 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9124 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009125
Georg Brandl3ee81df2008-05-17 18:14:43 +00009126- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
9127 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009128
Georg Brandl3ee81df2008-05-17 18:14:43 +00009129- PEP 3123: Provide forward compatibility with Python 3.0, while
9130 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
9131 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009132
Georg Brandl3ee81df2008-05-17 18:14:43 +00009133- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
9134 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009135
9136- Patch #1733960: Allow T_LONGLONG to accept ints.
9137
9138- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
9139

9143
9144- Fix some leftovers from the conversion from int to Py_ssize_t
9145 (relevant to strings and sequences of more than 2**31 items).
9146
9147- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9148 outside of pystate.c and should not be necessary.
9149
Georg Brandl3ee81df2008-05-17 18:14:43 +00009150- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9151 absolute imports. In earlier versions they might have used relative
9152 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009153
Georg Brandl3ee81df2008-05-17 18:14:43 +00009154- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9155 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009156
Georg Brandl3ee81df2008-05-17 18:14:43 +00009157- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
9158 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009164- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
9165 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
9166 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
9167 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00009168
Georg Brandl3ee81df2008-05-17 18:14:43 +00009169- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00009182- Removed the macfs module. It had been deprecated since Python 2.5.
9183 This lead to the deprecation of macostools.touched() as it relied
9184 solely on macfs and was a no-op under OS X.
