650
651- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
652 and later systems as is currently done for Python 3.x installers.
653 For 2.7.7 only, we will provide three installers:
654 the legacy deprecated 10.3+ 32-bit-only format;
655 the newer 10.5+ 32-bit-only format;
656 and the unchanged 10.6+ 64-/32-bit format.
657 Although binary installers will no longer be available from
658 python.org as of 2.7.8, it will still be possible to build from
659 source on 10.3.9 and 10.4 systems if necessary.
660 See Mac/BuildScript/README.txt for more information.

Ned Deily18fae3f2013-01-31 01:24:55 -08002040- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
2041 In particular, fix extension module build failures when trying to use
2042 32-bit-only installer Pythons on systems with Xcode 4 (currently
2043 OS X 10.8, 10.7, and optionally 10.6).
2044 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2045 * Since Xcode 4 removes ppc support, extension module builds now
2046 check for ppc compiler support and by default remove ppc and
2047 ppc64 archs when they are not available.
2048 * Extension module builds now revert to using system installed
2049 headers and libs (/usr and /System/Library) if the SDK used
2050 to build the interpreter is not installed or has moved.
2051 * Try to avoid building extension modules with deprecated
2052 and problematic Apple llvm-gcc compiler. If original compiler
2053 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01002417- Issue #12973: Fix overflow checks that invoked undefined behaviour in
2418 int.__pow__. These overflow checks were causing int.__pow__ to produce
2419 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01002420 compiler optimizing the check away. Also fix similar overflow checks
2421 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
2422 bugs caused test failures with recent versions of Clang.

2434 cleared by the garbage collector. This fixes a segfault when an instance
2435 and its type get caught in a reference cycle, and the instance's
2436 deallocator calls one of the methods on the type (e.g. when subclassing
2437 IOBase). Diagnosis and patch by Davide Rizzo.

Florent Xiclunac2279652012-02-12 14:49:03 +01002490- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002491 has left two versions of customize_compiler, the original in
2492 distutils.sysconfig and another copy in distutils.ccompiler, with some
2493 parts of distutils calling one and others using the other.

2495 is the case in 3.x.
2496
Ned Deily0d0ea482012-02-10 12:59:06 +01002497- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2498 Distutils-based packages with C extension modules may fail because
2499 Apple has removed gcc-4.2, the version used to build python.org
2500 64-bit/32-bit Pythons. If the user does not explicitly override
2501 the default C compiler by setting the CC environment variable,
2502 Distutils will now attempt to compile extension modules with clang
2503 if gcc-4.2 is required but not found. Also as a convenience, if
2504 the user does explicitly set CC, substitute its value as the default
2505 compiler in the Distutils LDSHARED configuration variable for OS X.
2506 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2507 SDK, neither of which are available in Xcode 4. This change does not
2508 attempt to override settings to support their use with Xcode 4.)

2618 arguments with the system default encoding just like the write() method
Éric Araujob21f51a2011-10-23 04:37:51 +02002619 does, instead of converting it to a raw buffer. This also fixes handling of

Ned Deily87e82bb2011-06-28 19:52:59 -07002758- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2759 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2760 interpreter process. This could cause failures in non-Distutils subprocesses
2761 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002762 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002763 deployment target only in the environment of each build subprocess. It is
2764 still possible to globally override the default by setting
2765 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2766 greater or equal to the default value, the value with which the interpreter
2767 was built.

Barry Warsawc5643282011-07-19 17:06:30 -04002795- sys.setcheckinterval() now updates the current ticker count as well as
2796 updating the check interval, so if the user decreases the check interval,
2797 the ticker doesn't have to wind down to zero from the old starting point
2798 before the new interval takes effect. And if the user increases the
2799 interval, it makes sure the new limit takes effect right away rather have an
2800 early task switch before recognizing the new interval.

3787 by Andrew Bennetts.

3796
Raymond Hettinger20397532010-09-12 02:11:45 +00003797- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3798 This prevents user-created self-referencing ordered dictionaries from
3799 becoming permanently uncollectable GC garbage. The downside is that
3800 removing __del__ means that the internal doubly-linked list has to wait for
3801 GC collection rather than freeing memory immediately when the refcnt drops
3802 to zero.

3811 original error is re-raised.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004260- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4261 start byte and the continuation byte(s) are now considered invalid, instead
4262 of the number of bytes specified by the start byte.
4263 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4264 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4265 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

4275 objects. (1) The comparison could incorrectly return True in some cases
4276 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +00004595- On Windows, ctypes does no longer check the stack before and after calling a
4596 foreign function. This allows to use the unmodified libffi library.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00004621 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
4622 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
4623 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

4643Core and Builtins
4644-----------------
4645
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004646- Issue #7301: Add environment variable $PYTHONWARNINGS.
4647
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004648- Issue #8329: Don't return the same lists from select.select when no fds are
4649 changed.
4650
Georg Brandlfee0f442010-05-22 21:26:21 +00004651- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004652 on 64-bit machines. The shift count for either left or right shift is
4653 permitted to be up to sys.maxsize.
4654
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004655- Ensure that tokenization of identifiers is not affected by locale.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00004659- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
4660
Georg Brandlfee0f442010-05-22 21:26:21 +00004661- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4662 with a non-empty format string. This is an effort to future-proof user
4663 code. If a derived class does not currently implement __format__ but later
4664 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004665 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004666 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004667

Victor Stinner66644262010-03-10 22:30:19 +00004681- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00004682 (SIGINT). If an error occurs while importing the site module, the error is

4698
Georg Brandlfee0f442010-05-22 21:26:21 +00004699- Issue #8257: The Decimal construct now accepts a float instance directly,
4700 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004701
4702 >>> Decimal(1.1)
4703 Decimal('1.100000000000000088817841970012523233890533447265625')
4704
Raymond Hettinger34c35b22010-04-03 10:22:00 +00004705- collections.Counter() now supports a subtract() method.
4706
Georg Brandlfee0f442010-05-22 21:26:21 +00004707- The functools module now has a total_ordering() class decorator to simplify
4708 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00004709
Georg Brandlfee0f442010-05-22 21:26:21 +00004710- The functools module also adds cmp_to_key() as a tool to transition old-style
4711 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00004712
Georg Brandlfee0f442010-05-22 21:26:21 +00004713- Issue #8294: The Fraction constructor now accepts Decimal and float instances
4714 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00004715
Georg Brandlfee0f442010-05-22 21:26:21 +00004716- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4717 InvalidOperation instead of returning False. (Comparisons involving a quiet
4718 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4719 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004720
Georg Brandlfee0f442010-05-22 21:26:21 +00004721- Issue #2531: Comparison operations between floats and Decimal instances now
4722 return a result based on the numeric values of the operands; previously they
4723 returned an arbitrary result based on the relative ordering of id(float) and
4724 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004725
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004726- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004727 argument `-` which tells it to read files to compile from stdin. Each line is
4728 read on demand and the named file is compiled immediately. (Original patch by
4729 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004730
Georg Brandlfee0f442010-05-22 21:26:21 +00004731- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00004734- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4735 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004736 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00004737
Georg Brandlfee0f442010-05-22 21:26:21 +00004738- Comparisons using one of <, <=, >, >= between a complex instance and a
4739 Fractions instance now raise TypeError instead of returning True/False. This
4740 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4741 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00004742

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004752- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00004753 didn't support chflags() (for example ZFS under FreeBSD). The error is now
4754 silenced.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00004840- Issue #8300: When passing a non-integer argument to struct.pack with any
4841 integer format code, struct.pack first attempts to convert the non-integer
4842 using its __index__ method. If that method is non-existent or raises
4843 TypeError it goes on to try the __int__ method, as described below.

Georg Brandlba83f822010-03-14 09:50:54 +00004845- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4846 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4847 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004848 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4849 inconsistent: __int__ was used for some integer codes but not for others, and
4850 the set of integer codes for which it was used differed between native packing
4851 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00005060- Issue #6292: For the moment at least, the test suite runs cleanly if python
R. David Murrayf28fd242010-02-23 00:24:49 +00005061 is run with the -OO flag. Tests requiring docstrings are skipped.

Georg Brandlba83f822010-03-14 09:50:54 +00005063- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
5064 now also used by regrtest to run all the tests in a temporary directory. The
5065 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
5066 Xicluna who helped with the patch.

Antoine Pitroubb445a12010-02-05 17:05:54 +00005082- Issue #5677: Explicitly forbid write operations on read-only file objects,
5083 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00005084 library would return a bogus result; on Solaris, it was possible to crash the
5085 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +00005098- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
5099 and add the additional members returned in an OSVERSIONINFOEX structure. The
5100 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00005103- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
5104 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
5105 returning NULL. The macro now returns a statically allocated empty string
5106 instead.

5116 strings,
5117 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
5118 numeric strings corresponding to subnormal values,
5119 (3) a memory leak for some values large enough to cause overflow, and
5120 (4) a number of flaws that could lead to incorrectly rounded results.

5139
Georg Brandlba83f822010-03-14 09:50:54 +00005140- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in

5142 by the XML specification, and are necessary when outputting e.g. PHP code in
5143 a processing instruction. Patch by Neil Muller.

Antoine Pitroud840e512010-02-04 20:20:18 +00005151- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00005152 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00005153 Also, raise ValueError rather than TypeError when an unknown TIPC address
5154 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005158- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00005159 file position when calling `truncate()`. It would previously change the file
5160 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005161 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
5162
Georg Brandlba83f822010-03-14 09:50:54 +00005163- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
5164 class used to represent files stored inside an archive. The new
5165 implementation is significantly faster and can be wrapped in a
5166 ``io.BufferedReader`` object for more speedups. It also solves an issue
5167 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
5168 Patch by Nir Aides.

Benjamin Petersona43f34c2010-01-25 03:31:13 +00005177
Georg Brandlba83f822010-03-14 09:50:54 +00005178- Issue #7748: Since unicode values are supported for some metadata options in
5179 Distutils, the DistributionMetadata get_* methods will now return an utf-8
5180 encoded string for them. This ensures that the upload and register commands
5181 send the correct values to PyPI without any error.

5256-----------------
5257
Georg Brandlba83f822010-03-14 09:50:54 +00005258- The ``__complex__()`` method is now looked up on the class of instances to
5259 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00005261- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
5262 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
5263
Mark Dickinson1b34d252010-01-01 17:27:30 +00005264- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005265 DeprecationWarning when passed a float argument where an integer was expected.
5266 These functions and methods now raise TypeError instead. The majority of the
5267 effects of this change are in the extension modules, but some core functions
5268 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5269 and many unicode/str methods.

5283 of integers: the result of a/b is now correctly rounded for ints a and b (at
5284 least on IEEE 754 platforms), and in particular does not depend on the
5285 internal representation of a long.

5293
Georg Brandlba83f822010-03-14 09:50:54 +00005294 These executables now work properly with the arch(1) command: ``arch -ppc
5295 python`` will start a universal binary version of python in PPC mode (unlike
5296 previous releases).

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005436

Georg Brandlba83f822010-03-14 09:50:54 +00005451- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5452 decimal string that's guaranteed to round back to x under correct rounding
5453 (with round-half-to-even rounding mode). Previously it gave a string based on
5454 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5455 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5456 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005457
Georg Brandlba83f822010-03-14 09:50:54 +00005458- Issue #7117: On almost all platforms: float-to-string and string-to-float
5459 conversions within Python are now correctly rounded. Places these conversions
5460 occur include: str for floats and complex numbers; the float and complex
5461 constructors; old-style and new-style numeric formatting; serialization and
5462 deserialization of floats and complex numbers using marshal, pickle and json;
5463 parsing of float and imaginary literals in Python code; Decimal-to-float
5464 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005465
Georg Brandlba83f822010-03-14 09:50:54 +00005466 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5467 providing correctly-rounded strtod and dtoa C functions. This code is
5468 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5469 the C compiler. There may be a small number of platforms on which correct
5470 operation of this code cannot be guaranteed, so the code is not used: notably,
5471 this applies to platforms where the C double format is not IEEE 754 binary64,
5472 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5473 and Python's configure script is unable to determine how to change the FPU
5474 precision. On these platforms conversions use the platform strtod and dtoa,
5475 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005476
Georg Brandlba83f822010-03-14 09:50:54 +00005477- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5478 uses the correctly-rounded string <-> float conversions described above (when
5479 available), and so produces correctly rounded results that will display nicely
5480 under the float repr. There are two related small changes: (1) round now
5481 accepts any class with an ``__index__()`` method for its second argument (but
5482 no longer accepts floats for the second argument), and (2) an excessively
5483 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5484 raises an exception.

5633 but with at least one decimal point and with a default precision
5634 of 12. Previously, the behavior the same but with a default precision of 6.
5635 This more closely matches ``str()``, and reduces surprises when adding

5637 complex.__format__ in the same way.

5770 collecting the oldest generation) so that allocating lots of objects without

Georg Brandlba83f822010-03-14 09:50:54 +00005777- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
5778 existing .py counterpart, override the co_filename attributes of all code
5779 objects if the original filename is obsolete (which can happen if the file has
5780 been renamed, moved, or if it is accessed through different paths). Patch by
5781 Ziga Seilnacht and Jean-Paul Calderone.

Georg Brandlba83f822010-03-14 09:50:54 +00005820- Issue #4445: Replace ``sizeof(PyStringObject)`` with
5821 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
5822 instances. On a typical machine this saves 3 bytes of memory (on average) per

5828
Georg Brandlba83f822010-03-14 09:50:54 +00005829- Issue #3689: The list reversed iterator now supports __length_hint__ instead

5834
Georg Brandlba83f822010-03-14 09:50:54 +00005835- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5836 file objects with closefd=False. The file descriptor is still kept open but
5837 the file object behaves like a closed file. The ``FileIO`` object also got a
5838 new readonly attribute ``closefd``.

5857
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005858- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00005859 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00005861- On windows, ``os.chdir()`` given unicode was not working if
5862 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5863 this code path is really executed because I cannot move to such directory on
5864 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00005866- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5867 element is temporarily replaced with an equivalent frozenset. But the
5868 eventual KeyError would always report the empty ``frozenset()`` as the missing
5869 key. Now it correctly refers to the initial element.

5888
Walter Dörwalded960ac2009-05-03 22:36:33 +00005889- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5890 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5891 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5892 of using the replace error handler in PyUnicode_DecodeUTF8().
5893
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005894- Issue #3739: The unicode-internal encoder now reports the number of characters

5896
Georg Brandlba83f822010-03-14 09:50:54 +00005897- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
5898 allocator will be automatically disabled when running under Valgrind. This
5899 gives improved memory leak detection when running under Valgrind, while taking
5900 advantage of pymalloc at other times.

7148 threads could return successfully while some Thread objects were still
7149 referenced. This also introduces a new private function: ``thread._count()``.

Georg Brandlba83f822010-03-14 09:50:54 +00007168 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
7169 the tests if DISPLAY is defined but can't be used.

7188 support, which does the conversion.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007291- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7292 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7293 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7294 ``printf`` function, whereas PyString_FromFormat has an independent
7295 implementation and uses "%zd" on all platforms for size_t values.
7296 This makes a difference on win64, where ``printf`` needs "%Id" to display
7297 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00007299- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

7303 object; previously an int would be returned for small values. the __long__
7304 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007314 was correctly parsed but parsing of subsequent arguments failed.
7315
Vinay Sajip35e3b032008-09-01 14:33:59 +00007316- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007317 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7318 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7319 when given a tuple of classes as second argument, were looking up
7320 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7321 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007460What's New in Python 2.6 beta 3?
7461================================
7462
Barry Warsaw07a4a382008-08-21 01:15:08 +00007463*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007464
7465Core and Builtins
7466-----------------
7467
Guido van Rossumf8402962008-08-20 15:01:50 +00007468- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7469 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7470 extensions do not automatically benefit from the class attribute
7471 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7472 to their tp_flags field if they care. This is a backwards
7473 compatibility feature; in 3.0, all types will use the cache by
7474 default.
7475
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007476- Keyword arguments can now follow starred arguments. (``f(a, *args,
7477 keyword=23)`` is now valid syntax.)
7478
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007479- ctypes function pointers that are COM methods have a boolean True
7480 value again.
7481
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007482- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7483 by denying s# to parse objects that have a releasebuffer procedure,
7484 and introducing s*.
7485
Georg Brandl1e13ea92008-08-11 09:07:59 +00007486- Issue #3537: Fix an assertion failure when an empty but presized dict
7487 object was stored in the freelist.
7488
Mark Dickinsonb6467572008-08-04 21:30:09 +00007489- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7490 ValueError consistently across platforms.
7491
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007492- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7493 (64bit Unix, for example), unichr() would truncate its argument and return
7494 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7495
Neal Norwitze7d8be82008-07-31 17:17:14 +00007496- Apply security patches from Apple.
7497
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007498- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7499 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7500
Antoine Pitrou92f82162008-07-25 22:22:08 +00007501- Issue #1819: function calls with several named parameters are now on
7502 average 35% faster (as measured by pybench).
7503
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007504- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7505 the python debugger steps into a class statement: the free variables (local
7506 variables defined in an outer scope) would be deleted from the outer scope.
7507
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007508- Issue #2620: Overflow checking when allocating or reallocating memory
7509 was not always being done properly in some python types and extension
7510 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7511 all been updated to perform better checks and places in the code that
7512 would previously leak memory on the error path when such an allocation
7513 failed have been fixed.

7516-------
7517
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007518- Issue #3612: Added some missing basic types in ctypes.wintypes.
7519
Benjamin Petersone977ad42008-08-20 01:42:01 +00007520- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7521 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7522
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007523- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7524 version reported by these tools does not necessarily follow the python
7525 version numbering scheme, so the module is less strict when parsing it.
7526
Nick Coghlanf70385a2008-08-18 12:42:46 +00007527- Issue #2235: Added Py3k warnings for types which will become unhashable
7528 under the stricter __hash__ inheritance rules in 3.0. Several types
7529 which did not meet the rules for hash invariants and were already
7530 unhashable in 3.0 have now been explicitly flagged as unhashable in
7531 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7532 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7533
Brett Cannon88f801d2008-08-18 00:46:22 +00007534- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7535 imported into the module but exposed as part of the module's API.
7536
Brett Cannon7b96f072008-08-18 00:41:11 +00007537- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7538
Brett Cannon46225e72008-08-18 00:36:52 +00007539- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
7540
Brett Cannon25c9d6a2008-08-17 22:10:11 +00007541- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7542
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007543- Issue #3575: Incremental decoder's decode function now takes bytearray
7544 by using 's*' instead of 't#'.
7545
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007546- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007547 fails unicode conversion on 2nd parameter. (windows only)
7548
Georg Brandl222e2082010-08-01 22:27:39 +00007549- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007550 in a redirect.
7551
Brett Cannonabe423e2008-08-16 21:47:07 +00007552- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007553 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007554
Facundo Batistaeb90b782008-08-16 14:44:07 +00007555- Issue #2776: fixed small issue when handling an URL with double slash
7556 after a 302 response in the case of not going through a proxy.
7557
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007558- Issue #2676: in the email package, content-type parsing was hanging on
7559 pathological input because of quadratic or exponential behaviour of a
7560 regular expression.
7561
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007562- Issue #3476: binary buffered reading through the new "io" library is now
7563 thread-safe.
7564
Brett Cannonbf3157b2008-08-14 05:00:03 +00007565- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7566 since mimetools itself is deprecated. Because modules are cached, all
7567 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7568
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007569- Issue #3134: shutil referenced undefined WindowsError symbol.
7570
Robert Schuppenies14646332008-08-10 11:01:53 +00007571- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7572 menu entries were not deleted.
7573
Brett Cannon83e81842008-08-09 23:30:55 +00007574- Copied the implementation of reduce() to _functools.reduce() to have a
7575 version that did not raise a DeprecationWarning under -3.
7576
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007577- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7578 a MemoryError rather than silently stop the iteration.
7579
Guido van Rossum59ce9012008-08-09 14:55:34 +00007580- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7581 to _sre.compile() will now be rejected. This should not affect anybody
7582 since the re.compile() function never generates invalid re-bytecode.
7583
Skip Montanaroa032bf42008-08-08 22:52:51 +00007584- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7585 upon first access it can be automatically initialized from the csv file if
7586 it wasn't initialized during instantiation.
7587
Brett Cannon3aa2a492008-08-06 22:28:09 +00007588- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7589 the reload() built-in has been removed.
7590
Brett Cannon7e30b672008-08-04 21:52:25 +00007591- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007592 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Brett Cannon7e30b672008-08-04 21:52:25 +00007598
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00007599- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
7600 raised an AttributeError.
7601
Benjamin Peterson01a24322008-07-28 23:35:27 +00007602- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00007603 asking for a specific length. This problem only affected files opened
7604 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007605
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00007606- Issue #3449: Update decimal module to use most recent specification
7607 (v. 1.68) and tests (v. 2.58) from IBM.
7608
Georg Brandl222e2082010-08-01 22:27:39 +00007609- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00007610

7613
Georg Brandlf9efabb2008-07-23 15:16:45 +00007614- Deprecate the "ast" parser function aliases.
7615
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007616- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
7617
7618- Issue #3303: Fix a crash in locale.strcoll() when calling it with
7619 invalid arguments.
7620
7621- Issue #3302: Fix several crashes when calling locale's gettext functions
7622 with None arguments.
7623
7624- Issue #3389: Allow resolving dotted names for handlers in logging
7625 configuration files.
7626
7627- Deprecate the sunaudio module for removal in Python 3.0.
7628
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00007629- Issue #3394: zipfile.writestr sets external attributes when passed a
7630 file name rather than a ZipInfo instance, so files are extracted with
7631 mode 0600 rather than 000 under Unix.
7632
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007633- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7634 argument in python 2.5, this broke code that subclassed Popen to include its
7635 own poll method. Fixed my moving _deadstate to an _internal_poll method.

7646 interaction with the tp_hash slot (added in 2.6b2) are now documented
7647
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007648- Issue #643841: The language reference now provides more detailed
7649 coverage of the lookup process for special methods. The disclaimers
7650 regarding lack of coverage of new-style classes have also been
7651 removed, since the coverage is now fairly reasonable.

7656
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007657*Release date: 17-Jul-2008*
7658
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007659Core and Builtins
7660-----------------
7661
Georg Brandl3e483f62008-07-16 22:57:41 +00007662- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7663 its methods now allow for items objects that can be converted to
7664 an integer using operator.index().
7665
Mark Dickinson64b7e502008-07-16 09:40:03 +00007666- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7667 produced a ValueError instead of giving the correct float.
7668
Eric Smitha5fa5a22008-07-16 00:11:49 +00007669- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7670 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7671
Mark Dickinson7103aa42008-07-15 19:08:33 +00007672- Issue #3008: the float type has a new instance method 'float.hex'
7673 and a new class method 'float.fromhex' to convert floating-point
7674 numbers to and from hexadecimal strings, respectively.
7675
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007676- Issue #2235: __hash__ is once again inherited by default. To allow
7677 collections.Hashable to remain meaningful in the presence of the
7678 default hash implementation (object.__hash__), it is now possible
7679 to explicit block inheritance of hash by setting __hash__=None at
7680 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7681 level.
7682
Nick Coghlanb028f502008-07-13 14:52:36 +00007683- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7684 the parent module cannot be found while performing an absolute import.
7685 This means that an incorrectly defined __package__ attribute will
7686 now only prevent relative imports in that module rather than causing
7687 all imports from that module to fail.
7688
Nick Coghlan14ff9942008-07-08 14:21:42 +00007689- Issue #2517: Allow unicode messages in Exceptions again by correctly
7690 bypassing the instance dictionary when looking up __unicode__ on
7691 new-style classes.
7692
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007693- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7694 set to a custom object whose write() method happens to install
7695 another file in sys.stdout.
7696
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007697- Issue #3088: Corrected a race condition in classes derived from
7698 threading.local: the first member set by a thread could be saved in
7699 another thread's dictionary.
7700
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007701- Issue #3004: Minor change to slice.indices(): the start and stop
7702 arguments are now treated identically, making the behaviour easier
7703 to describe and understand. For example, slice(None, -10,
7704 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7705 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7706 10, -1).
7707
Georg Brandl278fc502008-07-19 12:46:12 +00007708- Issue #3219: Calling a function with repeated keyword arguments,
7709 f(a=2, a=23), would not cause a syntax error. This was a regression
7710 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00008158 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008159
8160 This is controlled by the configure argument ``--with-universal-archs``:
8161
8162 - ``--with-universal-archs=all``: install 4-way universal
8163
8164 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8165
8166 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8167
8168 This option should be used in combination with ``--enable-universalsdk=``.
8169

Georg Brandl3ee81df2008-05-17 18:14:43 +00008219- Issue #1631171: Re-implement the 'warnings' module in C (the
8220 original Python code has been kept as backup). This will allow for
8221 using the 'warning's machinery in such places as the parser where
8222 use of pure Python code is not possible. Both the ``showarning()``
8223 and ``formatwarning()`` gain an optional 'line' argument which is
8224 not called by default for backwards-compatibility reasons. Setting
8225 ``warnings.showwarning()`` to an implementation that lacks support
8226 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008289- Issue #2550: The approach used by client/server code for obtaining
8290 ports to listen on in network-oriented tests has been refined in an
8291 effort to facilitate running multiple instances of the entire
8292 regression test suite in parallel without issue.
8293 test_support.bind_port() has been fixed such that it will always
8294 return a unique port -- which wasn't always the case with the
8295 previous implementation, especially if socket options had been set
8296 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8297 new implementation of bind_port() will actually raise an exception
8298 if it is passed an AF_INET/SOCK_STREAM socket with either the
8299 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8300 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8301 the socket it's been passed. This currently only applies to
8302 Windows. This option prevents any other sockets from binding to the
8303 host/port we've bound to, thus removing the possibility of the
8304 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8305 when a second SOCK_STREAM socket binds and accepts to a host/port
8306 that's already been bound by another socket. The optional preferred
8307 port parameter to bind_port() has been removed. Under no
8308 circumstances should tests be hard coding ports!
8309
8310 test_support.find_unused_port() has also been introduced, which will
8311 pass a temporary socket object to bind_port() in order to obtain an
8312 unused port. The temporary socket object is then closed and
8313 deleted, and the port is returned. This method should only be used
8314 for obtaining an unused port in order to pass to an external program
8315 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8316 a parameter to a server-oriented class that doesn't give you direct
8317 access to the underlying socket used.
8318
8319 Finally, test_support.HOST has been introduced, which should be used
8320 for the host argument of any relevant socket calls (i.e. bind and
8321 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008322
8323 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008324 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008325 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8326 test_asynchat and test_socket_ssl.
8327
Georg Brandl3ee81df2008-05-17 18:14:43 +00008328 It is now possible for multiple instances of the regression test
8329 suite to run in parallel without issue.

Thomas Heller78b8f442008-03-05 14:53:39 +00008533- The bundled libffi copy is now in sync with the recently released
8534 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008535 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
8536 files are used. On all linux systems the --with-system-ffi
8537 configure option defaults to "yes".

Eric Smitha73fbe72008-02-23 03:09:44 +00008608- Added the future_builtins module, which contains hex() and oct().
8609 These are the PEP 3127 version of these functions, designed to be
8610 compatible with the hex() and oct() builtins from Python 3.0. They
8611 differ slightly in their output formats from the existing, unchanged
8612 Python 2.6 builtins. The expected usage of the future_builtins
8613 module is:
8614 from future_builtins import hex, oct
8615
Eric Smith7ef40bf2008-02-20 23:34:22 +00008616- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8617 exponents for exponents with absolute value < 100. Follows C99
8618 standard. This is a change on Windows, which would use 3 digits.
8619 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8620 so that any alterations it does to the resulting string will be
8621 available in stringlib/formatter.h (for float.__format__).
8622
Eric Smith5a3c1352008-02-19 13:21:56 +00008623- Implemented PEP 3101, Advanced String Formatting. This adds a new
8624 builtin format(); a format() method for str and unicode; a
8625 __format__() method to object, str, unicode, int, long, float, and
8626 datetime; the class string.Formatter; and the C API
8627 PyObject_Format().
8628
Georg Brandl3ee81df2008-05-17 18:14:43 +00008629- Fixed several potential crashes, all caused by specially crafted
8630 __del__ methods exploiting objects in temporarily inconsistent
8631 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008632
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008633- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008634 prevent a possible crash: an Abstract Base Class would try to access
8635 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008636

Georg Brandl3ee81df2008-05-17 18:14:43 +00008640- Clear all free lists during a gc.collect() of the highest generation
8641 in order to allow pymalloc to free more arenas. Python may give back
8642 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008643
Georg Brandl3ee81df2008-05-17 18:14:43 +00008644- Issue #2045: Fix an infinite recursion triggered when printing a
8645 subclass of collections.defaultdict, if its default_factory is set
8646 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008647
Christian Heimesf75dbef2008-02-08 00:11:31 +00008648- Fixed a minor memory leak in dictobject.c. The content of the free
8649 list was not freed on interpreter shutdown.
8650
Georg Brandl21e99f42010-03-07 15:23:59 +00008651- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008652 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008653
Georg Brandl3ee81df2008-05-17 18:14:43 +00008654- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8655 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008656 to compact the internal free lists of pre-allocted ints and floats.
8657
Georg Brandl3ee81df2008-05-17 18:14:43 +00008658- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8659 calls. Python expected the return type int but the fork familie
8660 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008661
Georg Brandl3ee81df2008-05-17 18:14:43 +00008662- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8663 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008674- Patch #1473257: generator objects gain a gi_code attribute. This is
8675 the same object as the func_code attribute of the function that
8676 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008677
Georg Brandl3ee81df2008-05-17 18:14:43 +00008678- Issue #1920: "while 0" statements were completely removed by the
8679 compiler, even in the presence of an "else" clause, which is
8680 supposed to be run when the condition is false. Now the compiler
8681 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008682
Guido van Rossumeead05f2008-01-24 18:21:02 +00008683- A few crashers fixed: weakref_in_del.py (issue #1377858);
8684 loosing_dict_ref.py (issue #1303614, test67.py);
8685 borrowed_ref_[34].py (not in tracker).
8686
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008687- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008688 suppressed while an extension is loaded by calling SetErrorMode in
8689 dynload_win.c. The error is still reported properly.
8690
Georg Brandl3ee81df2008-05-17 18:14:43 +00008691- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008692 several extension methods and modules do not work without unicode
8693 support.
8694
Georg Brandl26543b12008-01-21 18:36:51 +00008695- Issue #1882: when compiling code from a string, encoding cookies in the
8696 second line of code were not always recognized correctly.
8697
Georg Brandl14404b62008-01-19 19:27:05 +00008698- Issue #1679: "0x" was taken as a valid integer literal.
8699
Georg Brandl6caad7d2008-01-26 14:19:22 +00008700- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008701 added.
8702
Christian Heimesc94e2b52008-01-14 04:13:37 +00008703- sys.float_info / PyFloat_GetInfo: The floating point information
8704 object was converted from a dict to a specialized structseq object.
8705
Georg Brandl3ee81df2008-05-17 18:14:43 +00008706- Patch #1816: Added sys.flags structseq. It exposes the status of
8707 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008708
Georg Brandl3ee81df2008-05-17 18:14:43 +00008709- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00008735 and INF. float("nan"), float("inf") and float("-inf") now work on
8736 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008737
Georg Brandl3ee81df2008-05-17 18:14:43 +00008738- Compiler now generates simpler and faster code for dictionary
8739 literals. The oparg for BUILD_MAP now indicates an estimated
8740 dictionary size. There is a new opcode, STORE_MAP, for adding
8741 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008770- Patch #1739468: Directories and zipfiles containing a __main__.py
8771 file can now be directly executed by passing their name to the
8772 interpreter. The directory/zipfile is automatically inserted as the
8773 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008775- Issue #1265: Fix a problem with sys.settrace, if the tracing
8776 function uses a generator expression when at the same time the
8777 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008778
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008779- sets and frozensets now have an isdisjoint() method.

8784
Georg Brandl21e99f42010-03-07 15:23:59 +00008785- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008786 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8787 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008788
Georg Brandl3ee81df2008-05-17 18:14:43 +00008789- Issue #1686386: Tuple's tp_repr did not take into account the
8790 possibility of having a self-referential tuple, which is possible
8791 from C code. Nor did object's tp_str consider that a type's tp_str
8792 could do something that could lead to an inifinite recursion.
8793 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8794 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008795
Georg Brandl3ee81df2008-05-17 18:14:43 +00008796- Issue #1164: It was possible to trigger deadlock when using the
8797 'print' statement to write to a file since the GIL was not released
8798 as needed. Now PyObject_Print() does the right thing along with
8799 various tp_print implementations of the built-in types and those in
8800 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008801
Georg Brandl3ee81df2008-05-17 18:14:43 +00008802- Issue #1147: Exceptions were directly allowing string exceptions in
8803 their throw() method even though string exceptions no longer
8804 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008805
Georg Brandl3ee81df2008-05-17 18:14:43 +00008806- Issue #1096: Prevent a segfault from getting the repr of a very
8807 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008808
Brett Cannon1e534b52007-09-07 04:18:30 +00008809- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008810 PyObject_Call() never calling back out to Python code to trigger
8811 recursion depth updates/checks. Required the creation of a static
8812 RuntimeError instance in case normalizing an exception put the
8813 recursion check value past its limit. Fixes crashers
8814 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008815

Neal Norwitz0ac60192007-05-27 04:08:54 +00008829- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008830 __*__ attributes. (Some already existed, e.g., __doc__ and
8831 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008832
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008833- Add -3 option to the interpreter to warn about features that are
8834 deprecated and will be changed/removed in Python 3.0.
8835
Georg Brandl2134e752007-05-21 20:34:16 +00008836- Patch #1686487: you can now pass any mapping after '**' in function
8837 calls.
8838
Collin Winter62903052007-05-18 23:11:24 +00008839- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008840 "except E as target:". This is to provide forwards compatibility
8841 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008842
Brett Cannon229cee22007-05-05 01:34:02 +00008843- Deprecate BaseException.message as per PEP 352.
8844
Georg Brandl3ee81df2008-05-17 18:14:43 +00008845- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008846 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008847
Vinay Sajip8549ce32007-05-06 17:53:37 +00008848- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008849 setting a plain string, ie don't expand to single letter identifiers.
8850
Raymond Hettinger13936692007-04-11 18:40:58 +00008851- Request #1191699: Slices can now be pickled.
8852
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008853- Request #1193128: str.translate() now allows a None argument for
8854 translations that only remove characters without re-mapping the
8855 remaining characters.
8856
Georg Brandl5cb76c12007-03-21 09:00:39 +00008857- Patch #1682205: a TypeError while unpacking an iterable is no longer
8858 masked by a generic one with the message "unpack non-sequence".
8859

8861
Guido van Rossum143b5642007-03-23 04:58:42 +00008862- Bug #1683368: The object.__init__() and object.__new__() methods are
8863 now stricter in rejecting excess arguments. The only time when
8864 either allows excess arguments is when it is not overridden and the
8865 other one is. For backwards compatibility, when both are
8866 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008867 warning later). Also, type.__init__() insists on the same signature
8868 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008869
Georg Brandl3ee81df2008-05-17 18:14:43 +00008870- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8871 object to complex using its __complex__() method before falling back
8872 to the __float__() method. Therefore, the functions in the cmath
8873 module now can operate on objects that define a __complex__()
8874 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008875
Georg Brandl3ee81df2008-05-17 18:14:43 +00008876- Patch #1623563: allow __class__ assignment for classes with
8877 __slots__. The old and the new class are still required to have the
8878 same slot names.

8884 ``object.__reduce_ex__()`` is called with an object that is faking
8885 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00008886
Georg Brandl3ee81df2008-05-17 18:14:43 +00008887- Patch #1680015: Don't modify __slots__ tuple if it contains an

8891
Georg Brandl7b9c5552007-03-12 14:30:05 +00008892- Bug #1678647: write a newline after printing an exception in any
8893 case, even when converting the value to a string failed.
8894
Georg Brandl871f1bc2007-03-12 13:17:36 +00008895- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008896 its argument, if it exists. If not, it will work like before. This
8897 allows customizing the output of dir() in the presence of a
8898 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008906- Patch #1491866: change the complex() constructor to allow
8907 parthensized forms. This means complex(repr(x)) now works instead of
8908 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008909
Georg Brandlaa2321b2007-03-07 00:40:28 +00008910- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008911 makes the filenames the warning module prints much more sensible
8912 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008913

Georg Brandl0fca97a2007-03-05 22:28:08 +00008925- Patch #1674228: when assigning a slice (old-style), check for the
8926 sq_ass_slice instead of the sq_slice slot.
8927
Georg Brandl3ee81df2008-05-17 18:14:43 +00008928- When printing an unraisable error, don't print exceptions. before
8929 the name. This duplicates the behavior whening normally printing
8930 exceptions.

9557 -- the failure just occurred later, with a more cumbersome
9558 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009833- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9834 with RFC 3207 and forgets any knowledge obtained from the server not
9835 obtained from the TLS negotiation itself. Patch contributed by Bill
9836 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009837
Georg Brandl3ee81df2008-05-17 18:14:43 +00009838- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009839 that the SMTP.starttls() caller no longer needs to call ehlo()
9840 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009841 does not claim to support starttls. Adds the
9842 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
9843 Fenner.

9923 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9924 silently miscode subclasses of those types. Now, it raises a
9925 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009926

Georg Brandl3ee81df2008-05-17 18:14:43 +00009941 time so that opening a database previously created with the DB_DUP
9942 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9943 opens. Specifically: dictionary assignment to a DB object will
9944 replace all values for a given key when the database allows
9945 duplicate values. DB users should use DB.put(k, v) when they want
9946 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009947

9953 characters with ASCII value less than 32. Also, it correctly quotes
9954 dots only if they occur on a single line, as opposed to the previous
9955 behavior of quoting dots if they are the second character of any
9956 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009957

10285
Georg Brandl3ee81df2008-05-17 18:14:43 +000010286- Unified naming convention for free lists and their limits. All free
10287 lists in Object/ are named ``free_list``, the counter ``numfree``
10288 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
10289 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +000010290
Georg Brandl3ee81df2008-05-17 18:14:43 +000010291- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
10292 to ``PyTuple_SetItem``, it can be used to populate a brand new

10305
Georg Brandl3ee81df2008-05-17 18:14:43 +000010306- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
10307 of w# format code incorrectly truncated the length to an int, even
10308 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10309 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010310
Georg Brandl3ee81df2008-05-17 18:14:43 +000010311- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

10328
10329- Fix some leftovers from the conversion from int to Py_ssize_t
10330 (relevant to strings and sequences of more than 2**31 items).
10331
10332- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10333 outside of pystate.c and should not be necessary.
10334
Georg Brandl3ee81df2008-05-17 18:14:43 +000010335- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10336 absolute imports. In earlier versions they might have used relative
10337 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010338
Georg Brandl3ee81df2008-05-17 18:14:43 +000010339- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10340 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010341
Georg Brandl3ee81df2008-05-17 18:14:43 +000010342- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +000010348- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10349 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10350 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10351 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010352

Georg Brandl3ee81df2008-05-17 18:14:43 +000010365- Removed the macfs module. It had been deprecated since Python 2.5.
10366 This lead to the deprecation of macostools.touched() as it relied
10367 solely on macfs and was a no-op under OS X.
