993
994- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
995 and later systems as is currently done for Python 3.x installers.
996 For 2.7.7 only, we will provide three installers:
997 the legacy deprecated 10.3+ 32-bit-only format;
998 the newer 10.5+ 32-bit-only format;
999 and the unchanged 10.6+ 64-/32-bit format.
1000 Although binary installers will no longer be available from
1001 python.org as of 2.7.8, it will still be possible to build from
1002 source on 10.3.9 and 10.4 systems if necessary.
1003 See Mac/BuildScript/README.txt for more information.

2388 * Since Xcode 4 removes ppc support, extension module builds now
2389 check for ppc compiler support and by default remove ppc and
2390 ppc64 archs when they are not available.
2391 * Extension module builds now revert to using system installed
2392 headers and libs (/usr and /System/Library) if the SDK used
2393 to build the interpreter is not installed or has moved.
2394 * Try to avoid building extension modules with deprecated
2395 and problematic Apple llvm-gcc compiler. If original compiler
2396 is not available, use clang instead by default.

2759
Mark Dickinsondbbed042011-09-19 16:38:08 +01002760- Issue #12973: Fix overflow checks that invoked undefined behaviour in
2761 int.__pow__. These overflow checks were causing int.__pow__ to produce
2762 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01002763 compiler optimizing the check away. Also fix similar overflow checks
2764 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
2765 bugs caused test failures with recent versions of Clang.

Antoine Pitrou16166452011-07-12 22:04:20 +02002776- Issue #12149: Update the method cache after a type's dictionnary gets
2777 cleared by the garbage collector. This fixes a segfault when an instance
2778 and its type get caught in a reference cycle, and the instance's
2779 deallocator calls one of the methods on the type (e.g. when subclassing
2780 IOBase). Diagnosis and patch by Davide Rizzo.
2781
Florent Xiclunaa1f948b2012-01-24 21:05:10 +01002782- Issue #12501: Remove Py3k warning for callable. callable() is supported

Victor Stinner08563d92011-05-30 23:44:13 +02002789 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
2790 raw_input() interrupted by CTRL+c.
2791
Łukasz Langa7a153902011-10-18 17:16:00 +02002792- Issue #10860: httplib now correctly handles an empty port after port
2793 delimiter in URLs.
2794

Florent Xiclunac2279652012-02-12 14:49:03 +01002833- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002834 has left two versions of customize_compiler, the original in
2835 distutils.sysconfig and another copy in distutils.ccompiler, with some
2836 parts of distutils calling one and others using the other.
2837 Complete the revert back to only having one in distutils.sysconfig as
2838 is the case in 3.x.
2839
Ned Deily0d0ea482012-02-10 12:59:06 +01002840- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2841 Distutils-based packages with C extension modules may fail because
2842 Apple has removed gcc-4.2, the version used to build python.org
2843 64-bit/32-bit Pythons. If the user does not explicitly override
2844 the default C compiler by setting the CC environment variable,
2845 Distutils will now attempt to compile extension modules with clang
2846 if gcc-4.2 is required but not found. Also as a convenience, if
2847 the user does explicitly set CC, substitute its value as the default
2848 compiler in the Distutils LDSHARED configuration variable for OS X.
2849 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2850 SDK, neither of which are available in Xcode 4. This change does not
2851 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003101- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3102 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3103 interpreter process. This could cause failures in non-Distutils subprocesses
3104 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003105 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003106 deployment target only in the environment of each build subprocess. It is
3107 still possible to globally override the default by setting
3108 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3109 greater or equal to the default value, the value with which the interpreter
3110 was built.

3139 updating the check interval, so if the user decreases the check interval,
3140 the ticker doesn't have to wind down to zero from the old starting point
3141 before the new interval takes effect. And if the user increases the
3142 interval, it makes sure the new limit takes effect right away rather have an
3143 early task switch before recognizing the new interval.

4141 This prevents user-created self-referencing ordered dictionaries from
4142 becoming permanently uncollectable GC garbage. The downside is that
4143 removing __del__ means that the internal doubly-linked list has to wait for
4144 GC collection rather than freeing memory immediately when the refcnt drops
4145 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004603- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4604 start byte and the continuation byte(s) are now considered invalid, instead
4605 of the number of bytes specified by the start byte.
4606 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4607 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4608 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

4618 objects. (1) The comparison could incorrectly return True in some cases
4619 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4620 (2) The comparison raised an OverflowError for large integers, leading

4816 operation raises multiple signals and more than one of those signals is
4817 trapped, the specification determines the order in which the signals should be
4818 handled. In many cases this order wasn't being followed, leading to the wrong

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00004964 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
4965 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
4966 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

4986Core and Builtins
4987-----------------
4988
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004989- Issue #7301: Add environment variable $PYTHONWARNINGS.
4990
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004991- Issue #8329: Don't return the same lists from select.select when no fds are
4992 changed.
4993
Georg Brandlfee0f442010-05-22 21:26:21 +00004994- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004995 on 64-bit machines. The shift count for either left or right shift is
4996 permitted to be up to sys.maxsize.
4997
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004998- Ensure that tokenization of identifiers is not affected by locale.
4999
Georg Brandlfee0f442010-05-22 21:26:21 +00005000- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00005001
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00005002- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
5003
Georg Brandlfee0f442010-05-22 21:26:21 +00005004- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
5005 with a non-empty format string. This is an effort to future-proof user
5006 code. If a derived class does not currently implement __format__ but later
5007 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00005008 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00005009 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00005010
Antoine Pitroua57df2c2010-03-31 21:32:15 +00005011- Issue #8268: Old-style classes (not just instances) now support weak

5023
Victor Stinner66644262010-03-10 22:30:19 +00005024- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00005025 (SIGINT). If an error occurs while importing the site module, the error is
5026 printed and Python exits. Initialize the GIL before importing the site

5041
Georg Brandlfee0f442010-05-22 21:26:21 +00005042- Issue #8257: The Decimal construct now accepts a float instance directly,
5043 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00005044
5045 >>> Decimal(1.1)
5046 Decimal('1.100000000000000088817841970012523233890533447265625')
5047
Raymond Hettinger34c35b22010-04-03 10:22:00 +00005048- collections.Counter() now supports a subtract() method.
5049
Georg Brandlfee0f442010-05-22 21:26:21 +00005050- The functools module now has a total_ordering() class decorator to simplify
5051 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00005052
Georg Brandlfee0f442010-05-22 21:26:21 +00005053- The functools module also adds cmp_to_key() as a tool to transition old-style
5054 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00005055
Georg Brandlfee0f442010-05-22 21:26:21 +00005056- Issue #8294: The Fraction constructor now accepts Decimal and float instances
5057 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00005058
Georg Brandlfee0f442010-05-22 21:26:21 +00005059- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
5060 InvalidOperation instead of returning False. (Comparisons involving a quiet
5061 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
5062 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00005063
Georg Brandlfee0f442010-05-22 21:26:21 +00005064- Issue #2531: Comparison operations between floats and Decimal instances now
5065 return a result based on the numeric values of the operands; previously they
5066 returned an arbitrary result based on the relative ordering of id(float) and
5067 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00005068
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00005069- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00005070 argument `-` which tells it to read files to compile from stdin. Each line is
5071 read on demand and the named file is compiled immediately. (Original patch by
5072 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00005073
Georg Brandlfee0f442010-05-22 21:26:21 +00005074- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00005077- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
5078 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00005079 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00005080
Georg Brandlfee0f442010-05-22 21:26:21 +00005081- Comparisons using one of <, <=, >, >= between a complex instance and a
5082 Fractions instance now raise TypeError instead of returning True/False. This
5083 makes Fraction <=> complex comparisons consistent with int <=> complex, float
5084 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00005085

5193 the set of integer codes for which it was used differed between native packing
5194 and standard packing.)

Antoine Pitroubb445a12010-02-05 17:05:54 +00005425- Issue #5677: Explicitly forbid write operations on read-only file objects,
5426 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00005427 library would return a bogus result; on Solaris, it was possible to crash the
5428 interpreter. Patch by Stefan Krah.

5439 very large step value.
Mark Dickinson36ecd672010-01-29 17:11:39 +00005440
Georg Brandlba83f822010-03-14 09:50:54 +00005441- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
5442 and add the additional members returned in an OSVERSIONINFOEX structure. The
5443 new members are service_pack_major, service_pack_minor, suite_mask, and
5444 product_type.
Eric Smithee931b72010-01-27 00:28:29 +00005445
Georg Brandlba83f822010-03-14 09:50:54 +00005446- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
5447 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
5448 returning NULL. The macro now returns a statically allocated empty string
5449 instead.
Antoine Pitroue80a6a42010-01-17 12:26:20 +00005450
Antoine Pitrou64672132010-01-13 07:55:48 +00005451- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

Georg Brandlba83f822010-03-14 09:50:54 +00005458 (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
5459 strings,
5460 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
5461 numeric strings corresponding to subnormal values,
5462 (3) a memory leak for some values large enough to cause overflow, and
5463 (4) a number of flaws that could lead to incorrectly rounded results.
5464
5465- Issue #7319, #7770: Silence ``DeprecationWarning`` by default when the -3
5466 option is not used.
Brett Cannon6fdd3dc2010-01-10 02:56:19 +00005467

5479
R. David Murray63e4fd72010-02-10 22:42:04 +00005480- Issue #7835: shelve should no longer produce mysterious warnings during
5481 interpreter shutdown.
5482
Georg Brandlba83f822010-03-14 09:50:54 +00005483- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
5484 XML processing instructions and comments. These raw characters are allowed
5485 by the XML specification, and are necessary when outputting e.g. PHP code in
5486 a processing instruction. Patch by Neil Muller.
Antoine Pitrou42fb6ab2010-02-09 17:08:05 +00005487

Georg Brandlba83f822010-03-14 09:50:54 +00005492- Issue #7851: logging: Clarification on logging configuration files.
Vinay Sajip0e6e97d2010-02-04 20:23:45 +00005493
Antoine Pitroud840e512010-02-04 20:20:18 +00005494- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00005495 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00005496 Also, raise ValueError rather than TypeError when an unknown TIPC address
5497 type is specified. Patch by Brian Curtin.
5498
Vinay Sajip28c382f2010-02-04 18:48:53 +00005499- logging: Implemented PEP 391.
5500
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005501- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00005502 file position when calling `truncate()`. It would previously change the file
5503 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005504 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
5505
Georg Brandlba83f822010-03-14 09:50:54 +00005506- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
5507 class used to represent files stored inside an archive. The new
5508 implementation is significantly faster and can be wrapped in a
5509 ``io.BufferedReader`` object for more speedups. It also solves an issue
5510 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
5511 Patch by Nir Aides.
Antoine Pitrou94c33eb2010-01-27 20:59:50 +00005512
Benjamin Peterson2deb5c72010-01-27 02:16:42 +00005513- Issue #7792: Registering non-classes to ABCs raised an obscure error.
5514
Georg Brandlba83f822010-03-14 09:50:54 +00005515- Removed the deprecated functions ``verify()`` and ``vereq()`` from
5516 Lib/test/test_support.py.

Georg Brandlba83f822010-03-14 09:50:54 +00005518- Issue #7773: Fix an UnboundLocalError in ``platform.linux_distribution()``
5519 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +00005520
Georg Brandlba83f822010-03-14 09:50:54 +00005521- Issue #7748: Since unicode values are supported for some metadata options in
5522 Distutils, the DistributionMetadata get_* methods will now return an utf-8
5523 encoded string for them. This ensures that the upload and register commands
5524 send the correct values to PyPI without any error.
Tarek Ziadéf14c7fc2010-01-24 00:33:32 +00005525

R. David Murrayed44dfa2010-01-16 05:15:17 +00005527 headers in multipart/signed MIME parts, which fixes one of the sources of
5528 invalid modifications to such parts by Generator.

5599-----------------
5600
Georg Brandlba83f822010-03-14 09:50:54 +00005601- The ``__complex__()`` method is now looked up on the class of instances to
5602 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00005603
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00005604- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
5605 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
5606
Mark Dickinson1b34d252010-01-01 17:27:30 +00005607- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005608 DeprecationWarning when passed a float argument where an integer was expected.
5609 These functions and methods now raise TypeError instead. The majority of the
5610 effects of this change are in the extension modules, but some core functions
5611 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5612 and many unicode/str methods.

5636
Georg Brandlba83f822010-03-14 09:50:54 +00005637 These executables now work properly with the arch(1) command: ``arch -ppc
5638 python`` will start a universal binary version of python in PPC mode (unlike
5639 previous releases).

5778 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005779

5781 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00005782

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00005793
Georg Brandlba83f822010-03-14 09:50:54 +00005794- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5795 decimal string that's guaranteed to round back to x under correct rounding
5796 (with round-half-to-even rounding mode). Previously it gave a string based on
5797 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5798 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5799 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005800
Georg Brandlba83f822010-03-14 09:50:54 +00005801- Issue #7117: On almost all platforms: float-to-string and string-to-float
5802 conversions within Python are now correctly rounded. Places these conversions
5803 occur include: str for floats and complex numbers; the float and complex
5804 constructors; old-style and new-style numeric formatting; serialization and
5805 deserialization of floats and complex numbers using marshal, pickle and json;
5806 parsing of float and imaginary literals in Python code; Decimal-to-float
5807 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005808
Georg Brandlba83f822010-03-14 09:50:54 +00005809 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5810 providing correctly-rounded strtod and dtoa C functions. This code is
5811 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5812 the C compiler. There may be a small number of platforms on which correct
5813 operation of this code cannot be guaranteed, so the code is not used: notably,
5814 this applies to platforms where the C double format is not IEEE 754 binary64,
5815 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5816 and Python's configure script is unable to determine how to change the FPU
5817 precision. On these platforms conversions use the platform strtod and dtoa,
5818 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005819
Georg Brandlba83f822010-03-14 09:50:54 +00005820- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5821 uses the correctly-rounded string <-> float conversions described above (when
5822 available), and so produces correctly rounded results that will display nicely
5823 under the float repr. There are two related small changes: (1) round now
5824 accepts any class with an ``__index__()`` method for its second argument (but
5825 no longer accepts floats for the second argument), and (2) an excessively
5826 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5827 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005970 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
5971 (2) parsing of strings representing infinities and nans was locale aware; and
5972 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00005974- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5975 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5976 but with at least one decimal point and with a default precision
5977 of 12. Previously, the behavior the same but with a default precision of 6.
5978 This more closely matches ``str()``, and reduces surprises when adding
5979 alignment flags to the empty presentation type. This also affects the new
5980 complex.__format__ in the same way.
5981
5982- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00006178- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
6179 file objects with closefd=False. The file descriptor is still kept open but
6180 the file object behaves like a closed file. The ``FileIO`` object also got a

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00006201- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00006204- On windows, ``os.chdir()`` given unicode was not working if

6206 this code path is really executed because I cannot move to such directory on
6207 win2k)

6210 element is temporarily replaced with an equivalent frozenset. But the
6211 eventual KeyError would always report the empty ``frozenset()`` as the missing
6212 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00006232- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
6233 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6234 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6235 of using the replace error handler in PyUnicode_DecodeUTF8().
6236
Walter Dörwald726ba8e2009-05-06 14:32:35 +00006237- Issue #3739: The unicode-internal encoder now reports the number of characters

6239
Georg Brandlba83f822010-03-14 09:50:54 +00006240- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

6242 gives improved memory leak detection when running under Valgrind, while taking
6243 advantage of pymalloc at other times.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00007509- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
7510 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00007511 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
7512 the tests if DISPLAY is defined but can't be used.

7516
Georg Brandlba83f822010-03-14 09:50:54 +00007517- Issue #5354: New test support function import_fresh_module() makes it easy to
7518 import both normal and optimised versions of modules. test_heapq and
7519 test_warnings have been adjusted to use it, tests for other modules with both
7520 C and Python implementations in the stdlib can be adjusted to use it over
7521 time.

Georg Brandlba83f822010-03-14 09:50:54 +00007529- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
7530 should cause a test to be skipped are now done using import_module from test
7531 support, which does the conversion.

7633
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007634- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7635 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7636 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7637 ``printf`` function, whereas PyString_FromFormat has an independent
7638 implementation and uses "%zd" on all platforms for size_t values.
7639 This makes a difference on win64, where ``printf`` needs "%Id" to display
7640 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00007642- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

7646 object; previously an int would be returned for small values. the __long__
7647 method is allowed to return either an int or a long, but the behaviour of
7648 float objects should not change to respect backward compatibility.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007657 was correctly parsed but parsing of subsequent arguments failed.
7658
Vinay Sajip35e3b032008-09-01 14:33:59 +00007659- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007660 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7661 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7662 when given a tuple of classes as second argument, were looking up
7663 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7664 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007803What's New in Python 2.6 beta 3?
7804================================
7805
Barry Warsaw07a4a382008-08-21 01:15:08 +00007806*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007807
7808Core and Builtins
7809-----------------
7810
Guido van Rossumf8402962008-08-20 15:01:50 +00007811- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7812 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7813 extensions do not automatically benefit from the class attribute
7814 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7815 to their tp_flags field if they care. This is a backwards
7816 compatibility feature; in 3.0, all types will use the cache by
7817 default.
7818
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007819- Keyword arguments can now follow starred arguments. (``f(a, *args,
7820 keyword=23)`` is now valid syntax.)
7821
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007822- ctypes function pointers that are COM methods have a boolean True
7823 value again.
7824
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007825- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7826 by denying s# to parse objects that have a releasebuffer procedure,
7827 and introducing s*.
7828
Georg Brandl1e13ea92008-08-11 09:07:59 +00007829- Issue #3537: Fix an assertion failure when an empty but presized dict
7830 object was stored in the freelist.
7831
Mark Dickinsonb6467572008-08-04 21:30:09 +00007832- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7833 ValueError consistently across platforms.
7834
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007835- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7836 (64bit Unix, for example), unichr() would truncate its argument and return
7837 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7838
Neal Norwitze7d8be82008-07-31 17:17:14 +00007839- Apply security patches from Apple.
7840
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007841- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7842 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7843
Antoine Pitrou92f82162008-07-25 22:22:08 +00007844- Issue #1819: function calls with several named parameters are now on
7845 average 35% faster (as measured by pybench).
7846
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007847- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7848 the python debugger steps into a class statement: the free variables (local
7849 variables defined in an outer scope) would be deleted from the outer scope.
7850
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007851- Issue #2620: Overflow checking when allocating or reallocating memory
7852 was not always being done properly in some python types and extension
7853 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7854 all been updated to perform better checks and places in the code that
7855 would previously leak memory on the error path when such an allocation
7856 failed have been fixed.

7859-------
7860
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007861- Issue #3612: Added some missing basic types in ctypes.wintypes.
7862
Benjamin Petersone977ad42008-08-20 01:42:01 +00007863- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7864 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7865
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007866- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7867 version reported by these tools does not necessarily follow the python
7868 version numbering scheme, so the module is less strict when parsing it.
7869
Nick Coghlanf70385a2008-08-18 12:42:46 +00007870- Issue #2235: Added Py3k warnings for types which will become unhashable
7871 under the stricter __hash__ inheritance rules in 3.0. Several types
7872 which did not meet the rules for hash invariants and were already
7873 unhashable in 3.0 have now been explicitly flagged as unhashable in
7874 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7875 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7876
Brett Cannon88f801d2008-08-18 00:46:22 +00007877- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7878 imported into the module but exposed as part of the module's API.
7879
Brett Cannon7b96f072008-08-18 00:41:11 +00007880- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7881
Brett Cannon46225e72008-08-18 00:36:52 +00007882- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
7883
Brett Cannon25c9d6a2008-08-17 22:10:11 +00007884- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7885
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007886- Issue #3575: Incremental decoder's decode function now takes bytearray
7887 by using 's*' instead of 't#'.
7888
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007889- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007890 fails unicode conversion on 2nd parameter. (windows only)
7891
Georg Brandl222e2082010-08-01 22:27:39 +00007892- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007893 in a redirect.
7894
Brett Cannonabe423e2008-08-16 21:47:07 +00007895- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007896 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007897
Facundo Batistaeb90b782008-08-16 14:44:07 +00007898- Issue #2776: fixed small issue when handling an URL with double slash
7899 after a 302 response in the case of not going through a proxy.
7900
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007901- Issue #2676: in the email package, content-type parsing was hanging on
7902 pathological input because of quadratic or exponential behaviour of a
7903 regular expression.
7904
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007905- Issue #3476: binary buffered reading through the new "io" library is now
7906 thread-safe.
7907
Brett Cannonbf3157b2008-08-14 05:00:03 +00007908- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7909 since mimetools itself is deprecated. Because modules are cached, all
7910 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7911
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007912- Issue #3134: shutil referenced undefined WindowsError symbol.
7913
Robert Schuppenies14646332008-08-10 11:01:53 +00007914- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7915 menu entries were not deleted.
7916
Brett Cannon83e81842008-08-09 23:30:55 +00007917- Copied the implementation of reduce() to _functools.reduce() to have a
7918 version that did not raise a DeprecationWarning under -3.
7919
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007920- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7921 a MemoryError rather than silently stop the iteration.
7922
Guido van Rossum59ce9012008-08-09 14:55:34 +00007923- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7924 to _sre.compile() will now be rejected. This should not affect anybody
7925 since the re.compile() function never generates invalid re-bytecode.
7926
Skip Montanaroa032bf42008-08-08 22:52:51 +00007927- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7928 upon first access it can be automatically initialized from the csv file if
7929 it wasn't initialized during instantiation.
7930
Brett Cannon3aa2a492008-08-06 22:28:09 +00007931- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7932 the reload() built-in has been removed.
7933
Brett Cannon7e30b672008-08-04 21:52:25 +00007934- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007935 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

7940 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00007941
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00007942- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
7943 raised an AttributeError.
7944
Benjamin Peterson01a24322008-07-28 23:35:27 +00007945- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00007946 asking for a specific length. This problem only affected files opened
7947 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007948
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00007949- Issue #3449: Update decimal module to use most recent specification
7950 (v. 1.68) and tests (v. 2.58) from IBM.
7951
Georg Brandl222e2082010-08-01 22:27:39 +00007952- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00007953

7956
Georg Brandlf9efabb2008-07-23 15:16:45 +00007957- Deprecate the "ast" parser function aliases.
7958
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007959- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
7960
7961- Issue #3303: Fix a crash in locale.strcoll() when calling it with
7962 invalid arguments.
7963
7964- Issue #3302: Fix several crashes when calling locale's gettext functions
7965 with None arguments.
7966
7967- Issue #3389: Allow resolving dotted names for handlers in logging
7968 configuration files.
7969
7970- Deprecate the sunaudio module for removal in Python 3.0.
7971
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00007972- Issue #3394: zipfile.writestr sets external attributes when passed a
7973 file name rather than a ZipInfo instance, so files are extracted with
7974 mode 0600 rather than 000 under Unix.
7975
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007976- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7977 argument in python 2.5, this broke code that subclassed Popen to include its
7978 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00007988- Issue #2235: the C API function PyObject_HashNotImplemented and its
7989 interaction with the tp_hash slot (added in 2.6b2) are now documented
7990
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007991- Issue #643841: The language reference now provides more detailed
7992 coverage of the lookup process for special methods. The disclaimers
7993 regarding lack of coverage of new-style classes have also been
7994 removed, since the coverage is now fairly reasonable.

8003-----------------
8004
Georg Brandl3e483f62008-07-16 22:57:41 +00008005- Issue #3156: Fix inconsistent behavior of the bytearray type: all
8006 its methods now allow for items objects that can be converted to
8007 an integer using operator.index().
8008
Mark Dickinson64b7e502008-07-16 09:40:03 +00008009- Issue #3360: Fix incorrect parsing of '020000000000.0', which
8010 produced a ValueError instead of giving the correct float.
8011
Eric Smitha5fa5a22008-07-16 00:11:49 +00008012- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
8013 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
8014
Mark Dickinson7103aa42008-07-15 19:08:33 +00008015- Issue #3008: the float type has a new instance method 'float.hex'
8016 and a new class method 'float.fromhex' to convert floating-point
8017 numbers to and from hexadecimal strings, respectively.
8018
Nick Coghlan6d6bd442008-07-15 15:40:22 +00008019- Issue #2235: __hash__ is once again inherited by default. To allow
8020 collections.Hashable to remain meaningful in the presence of the
8021 default hash implementation (object.__hash__), it is now possible
8022 to explicit block inheritance of hash by setting __hash__=None at
8023 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8024 level.
8025
Nick Coghlanb028f502008-07-13 14:52:36 +00008026- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8027 the parent module cannot be found while performing an absolute import.
8028 This means that an incorrectly defined __package__ attribute will
8029 now only prevent relative imports in that module rather than causing
8030 all imports from that module to fail.
8031
Nick Coghlan14ff9942008-07-08 14:21:42 +00008032- Issue #2517: Allow unicode messages in Exceptions again by correctly
8033 bypassing the instance dictionary when looking up __unicode__ on
8034 new-style classes.
8035
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00008036- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
8037 set to a custom object whose write() method happens to install
8038 another file in sys.stdout.

8042 another thread's dictionary.
8043
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008044- Issue #3004: Minor change to slice.indices(): the start and stop
8045 arguments are now treated identically, making the behaviour easier
8046 to describe and understand. For example, slice(None, -10,
8047 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8048 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8049 10, -1).
8050
Georg Brandl278fc502008-07-19 12:46:12 +00008051- Issue #3219: Calling a function with repeated keyword arguments,
8052 f(a=2, a=23), would not cause a syntax error. This was a regression
8053 from 2.4 caused by the switch to the new compiler.

8500 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00008501 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008502
8503 This is controlled by the configure argument ``--with-universal-archs``:
8504
8505 - ``--with-universal-archs=all``: install 4-way universal
8506
8507 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8508
8509 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8510
8511 This option should be used in combination with ``--enable-universalsdk=``.
8512
8513 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00008548- Issue #2670: Fix a failure in urllib2.build_opener(), when passed
8549 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00008550
Christian Heimese74c8f22008-04-19 02:23:57 +00008551- Added kill, terminate and send_signal(sig) to subprocess.Popen.

8554 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00008555

Georg Brandl3ee81df2008-05-17 18:14:43 +00008562- Issue #1631171: Re-implement the 'warnings' module in C (the
8563 original Python code has been kept as backup). This will allow for
8564 using the 'warning's machinery in such places as the parser where
8565 use of pure Python code is not possible. Both the ``showarning()``
8566 and ``formatwarning()`` gain an optional 'line' argument which is
8567 not called by default for backwards-compatibility reasons. Setting
8568 ``warnings.showwarning()`` to an implementation that lacks support
8569 for the ``line`` argument will raise a DeprecationWarning.

8593
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00008594- The getpass module has been improved on Unix. It now uses /dev/tty
8595 by default and uses stderr instead of stdout. A GetPassWarning is
8596 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00008597

Georg Brandl3ee81df2008-05-17 18:14:43 +00008611- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00008612 extension modules between 32 and 64 bit platforms. See the distutls

8626 script environment. This supports setup.py scripts that refer to
8627 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008632- Issue #2550: The approach used by client/server code for obtaining
8633 ports to listen on in network-oriented tests has been refined in an
8634 effort to facilitate running multiple instances of the entire
8635 regression test suite in parallel without issue.
8636 test_support.bind_port() has been fixed such that it will always
8637 return a unique port -- which wasn't always the case with the
8638 previous implementation, especially if socket options had been set
8639 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8640 new implementation of bind_port() will actually raise an exception
8641 if it is passed an AF_INET/SOCK_STREAM socket with either the
8642 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8643 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8644 the socket it's been passed. This currently only applies to
8645 Windows. This option prevents any other sockets from binding to the
8646 host/port we've bound to, thus removing the possibility of the
8647 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8648 when a second SOCK_STREAM socket binds and accepts to a host/port
8649 that's already been bound by another socket. The optional preferred
8650 port parameter to bind_port() has been removed. Under no
8651 circumstances should tests be hard coding ports!
8652
8653 test_support.find_unused_port() has also been introduced, which will
8654 pass a temporary socket object to bind_port() in order to obtain an
8655 unused port. The temporary socket object is then closed and
8656 deleted, and the port is returned. This method should only be used
8657 for obtaining an unused port in order to pass to an external program
8658 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8659 a parameter to a server-oriented class that doesn't give you direct
8660 access to the underlying socket used.
8661
8662 Finally, test_support.HOST has been introduced, which should be used
8663 for the host argument of any relevant socket calls (i.e. bind and
8664 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008665
8666 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008667 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008668 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8669 test_asynchat and test_socket_ssl.
8670
Georg Brandl3ee81df2008-05-17 18:14:43 +00008671 It is now possible for multiple instances of the regression test
8672 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008951- Added the future_builtins module, which contains hex() and oct().
8952 These are the PEP 3127 version of these functions, designed to be
8953 compatible with the hex() and oct() builtins from Python 3.0. They
8954 differ slightly in their output formats from the existing, unchanged
8955 Python 2.6 builtins. The expected usage of the future_builtins
8956 module is:
8957 from future_builtins import hex, oct
8958
Eric Smith7ef40bf2008-02-20 23:34:22 +00008959- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8960 exponents for exponents with absolute value < 100. Follows C99
8961 standard. This is a change on Windows, which would use 3 digits.
8962 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8963 so that any alterations it does to the resulting string will be
8964 available in stringlib/formatter.h (for float.__format__).
8965
Eric Smith5a3c1352008-02-19 13:21:56 +00008966- Implemented PEP 3101, Advanced String Formatting. This adds a new
8967 builtin format(); a format() method for str and unicode; a
8968 __format__() method to object, str, unicode, int, long, float, and
8969 datetime; the class string.Formatter; and the C API
8970 PyObject_Format().
8971
Georg Brandl3ee81df2008-05-17 18:14:43 +00008972- Fixed several potential crashes, all caused by specially crafted
8973 __del__ methods exploiting objects in temporarily inconsistent
8974 state.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00008976- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008977 prevent a possible crash: an Abstract Base Class would try to access
8978 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008979

Georg Brandl3ee81df2008-05-17 18:14:43 +00008983- Clear all free lists during a gc.collect() of the highest generation
8984 in order to allow pymalloc to free more arenas. Python may give back
8985 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008986
Georg Brandl3ee81df2008-05-17 18:14:43 +00008987- Issue #2045: Fix an infinite recursion triggered when printing a
8988 subclass of collections.defaultdict, if its default_factory is set
8989 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008990
Christian Heimesf75dbef2008-02-08 00:11:31 +00008991- Fixed a minor memory leak in dictobject.c. The content of the free
8992 list was not freed on interpreter shutdown.
8993
Georg Brandl21e99f42010-03-07 15:23:59 +00008994- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008995 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008996
Georg Brandl3ee81df2008-05-17 18:14:43 +00008997- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8998 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008999 to compact the internal free lists of pre-allocted ints and floats.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009001- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
9002 calls. Python expected the return type int but the fork familie
9003 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00009004
Georg Brandl3ee81df2008-05-17 18:14:43 +00009005- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00009017- Patch #1473257: generator objects gain a gi_code attribute. This is
9018 the same object as the func_code attribute of the function that
9019 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00009020
Georg Brandl3ee81df2008-05-17 18:14:43 +00009021- Issue #1920: "while 0" statements were completely removed by the
9022 compiler, even in the presence of an "else" clause, which is
9023 supposed to be run when the condition is false. Now the compiler
9024 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009025
Guido van Rossumeead05f2008-01-24 18:21:02 +00009026- A few crashers fixed: weakref_in_del.py (issue #1377858);
9027 loosing_dict_ref.py (issue #1303614, test67.py);
9028 borrowed_ref_[34].py (not in tracker).
9029
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00009030- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00009031 suppressed while an extension is loaded by calling SetErrorMode in
9032 dynload_win.c. The error is still reported properly.
9033
Georg Brandl3ee81df2008-05-17 18:14:43 +00009034- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009035 several extension methods and modules do not work without unicode
9036 support.
9037
Georg Brandl26543b12008-01-21 18:36:51 +00009038- Issue #1882: when compiling code from a string, encoding cookies in the
9039 second line of code were not always recognized correctly.
9040
Georg Brandl14404b62008-01-19 19:27:05 +00009041- Issue #1679: "0x" was taken as a valid integer literal.
9042
Georg Brandl6caad7d2008-01-26 14:19:22 +00009043- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009044 added.
9045
Christian Heimesc94e2b52008-01-14 04:13:37 +00009046- sys.float_info / PyFloat_GetInfo: The floating point information
9047 object was converted from a dict to a specialized structseq object.
9048
Georg Brandl3ee81df2008-05-17 18:14:43 +00009049- Patch #1816: Added sys.flags structseq. It exposes the status of
9050 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009051
Georg Brandl3ee81df2008-05-17 18:14:43 +00009052- Objects/structseq.c: Implemented new structseq representation. The

9054 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009055
Georg Brandl3ee81df2008-05-17 18:14:43 +00009056- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00009078 and INF. float("nan"), float("inf") and float("-inf") now work on
9079 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009080
Georg Brandl3ee81df2008-05-17 18:14:43 +00009081- Compiler now generates simpler and faster code for dictionary
9082 literals. The oparg for BUILD_MAP now indicates an estimated
9083 dictionary size. There is a new opcode, STORE_MAP, for adding
9084 entries to the dictionary.

Georg Brandl21e99f42010-03-07 15:23:59 +00009128- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009129 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9130 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009131
Georg Brandl3ee81df2008-05-17 18:14:43 +00009132- Issue #1686386: Tuple's tp_repr did not take into account the
9133 possibility of having a self-referential tuple, which is possible
9134 from C code. Nor did object's tp_str consider that a type's tp_str
9135 could do something that could lead to an inifinite recursion.
9136 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9137 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009138
Georg Brandl3ee81df2008-05-17 18:14:43 +00009139- Issue #1164: It was possible to trigger deadlock when using the
9140 'print' statement to write to a file since the GIL was not released
9141 as needed. Now PyObject_Print() does the right thing along with
9142 various tp_print implementations of the built-in types and those in
9143 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009144
Georg Brandl3ee81df2008-05-17 18:14:43 +00009145- Issue #1147: Exceptions were directly allowing string exceptions in
9146 their throw() method even though string exceptions no longer
9147 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00009148
Georg Brandl3ee81df2008-05-17 18:14:43 +00009149- Issue #1096: Prevent a segfault from getting the repr of a very
9150 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00009151
Brett Cannon1e534b52007-09-07 04:18:30 +00009152- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009153 PyObject_Call() never calling back out to Python code to trigger
9154 recursion depth updates/checks. Required the creation of a static
9155 RuntimeError instance in case normalizing an exception put the
9156 recursion check value past its limit. Fixes crashers
9157 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00009158

Neal Norwitz0ac60192007-05-27 04:08:54 +00009172- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00009173 __*__ attributes. (Some already existed, e.g., __doc__ and
9174 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00009175
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00009176- Add -3 option to the interpreter to warn about features that are
9177 deprecated and will be changed/removed in Python 3.0.
9178
Georg Brandl2134e752007-05-21 20:34:16 +00009179- Patch #1686487: you can now pass any mapping after '**' in function
9180 calls.
9181
Collin Winter62903052007-05-18 23:11:24 +00009182- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009183 "except E as target:". This is to provide forwards compatibility
9184 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00009191- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009192 setting a plain string, ie don't expand to single letter identifiers.
9193
Raymond Hettinger13936692007-04-11 18:40:58 +00009194- Request #1191699: Slices can now be pickled.
9195
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00009196- Request #1193128: str.translate() now allows a None argument for
9197 translations that only remove characters without re-mapping the
9198 remaining characters.
9199
Georg Brandl5cb76c12007-03-21 09:00:39 +00009200- Patch #1682205: a TypeError while unpacking an iterable is no longer

9204
Guido van Rossum143b5642007-03-23 04:58:42 +00009205- Bug #1683368: The object.__init__() and object.__new__() methods are
9206 now stricter in rejecting excess arguments. The only time when
9207 either allows excess arguments is when it is not overridden and the
9208 other one is. For backwards compatibility, when both are
9209 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009210 warning later). Also, type.__init__() insists on the same signature
9211 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00009212
Georg Brandl3ee81df2008-05-17 18:14:43 +00009213- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9214 object to complex using its __complex__() method before falling back
9215 to the __float__() method. Therefore, the functions in the cmath
9216 module now can operate on objects that define a __complex__()
9217 method.

9228 its type.

9234
Georg Brandl7b9c5552007-03-12 14:30:05 +00009235- Bug #1678647: write a newline after printing an exception in any
9236 case, even when converting the value to a string failed.
9237
Georg Brandl871f1bc2007-03-12 13:17:36 +00009238- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009239 its argument, if it exists. If not, it will work like before. This
9240 allows customizing the output of dir() in the presence of a
9241 __getattr__().

9250 parthensized forms. This means complex(repr(x)) now works instead of
9251 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00009252
Georg Brandlaa2321b2007-03-07 00:40:28 +00009253- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009254 makes the filenames the warning module prints much more sensible
9255 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00009256

Georg Brandl0fca97a2007-03-05 22:28:08 +00009268- Patch #1674228: when assigning a slice (old-style), check for the
9269 sq_ass_slice instead of the sq_slice slot.
9270
Georg Brandl3ee81df2008-05-17 18:14:43 +00009271- When printing an unraisable error, don't print exceptions. before
9272 the name. This duplicates the behavior whening normally printing
9273 exceptions.

10114 partial fix for Bug #1574584.
10115
Georg Brandl3ee81df2008-05-17 18:14:43 +000010116- Fix turtle so that time.sleep is imported for the entire library.

10169 the first chunk fed to the decoder started with a BOM, but was
10170 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +000010171
Georg Brandl3ee81df2008-05-17 18:14:43 +000010172- The implementation of UnicodeError objects has been simplified
10173 (start and end attributes are now stored directly as Py_ssize_t
10174 members).

10179 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +000010180
Georg Brandl3ee81df2008-05-17 18:14:43 +000010181- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +000010182 that the SMTP.starttls() caller no longer needs to call ehlo()
10183 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +000010184 does not claim to support starttls. Adds the
10185 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
10186 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010228- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +000010229 works as expected. ``mmap.find`` also takes an optional ``end``

10266 complex, tuple, list, dict, set, and frozenset. Formerly, it would
10267 silently miscode subclasses of those types. Now, it raises a
10268 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +000010269

Georg Brandl3ee81df2008-05-17 18:14:43 +000010284 time so that opening a database previously created with the DB_DUP
10285 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10286 opens. Specifically: dictionary assignment to a DB object will
10287 replace all values for a given key when the database allows
10288 duplicate values. DB users should use DB.put(k, v) when they want
10289 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010290

Georg Brandl3ee81df2008-05-17 18:14:43 +000010295- Patch #1185447: binascii.b2a_qp() now correctly quotes binary
10296 characters with ASCII value less than 32. Also, it correctly quotes
10297 dots only if they occur on a single line, as opposed to the previous
10298 behavior of quoting dots if they are the second character of any
10299 line.
Georg Brandl4aef7272007-03-13 22:49:43 +000010300

10628
Georg Brandl3ee81df2008-05-17 18:14:43 +000010629- Unified naming convention for free lists and their limits. All free
10630 lists in Object/ are named ``free_list``, the counter ``numfree``
10631 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
10632 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +000010633
Georg Brandl3ee81df2008-05-17 18:14:43 +000010634- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
10635 to ``PyTuple_SetItem``, it can be used to populate a brand new

10648
Georg Brandl3ee81df2008-05-17 18:14:43 +000010649- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
10650 of w# format code incorrectly truncated the length to an int, even
10651 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10652 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010653
Georg Brandl3ee81df2008-05-17 18:14:43 +000010654- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

10671
10672- Fix some leftovers from the conversion from int to Py_ssize_t
10673 (relevant to strings and sequences of more than 2**31 items).
10674
10675- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10676 outside of pystate.c and should not be necessary.
10677
Georg Brandl3ee81df2008-05-17 18:14:43 +000010678- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10679 absolute imports. In earlier versions they might have used relative
10680 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010681
Georg Brandl3ee81df2008-05-17 18:14:43 +000010682- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10683 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010684
Georg Brandl3ee81df2008-05-17 18:14:43 +000010685- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +000010691- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10692 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10693 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10694 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010695

Georg Brandl3ee81df2008-05-17 18:14:43 +000010708- Removed the macfs module. It had been deprecated since Python 2.5.
10709 This lead to the deprecation of macostools.touched() as it relied
10710 solely on macfs and was a no-op under OS X.
