1242
1243- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
1244 and later systems as is currently done for Python 3.x installers.
1245 For 2.7.7 only, we will provide three installers:
1246 the legacy deprecated 10.3+ 32-bit-only format;
1247 the newer 10.5+ 32-bit-only format;
1248 and the unchanged 10.6+ 64-/32-bit format.
1249 Although binary installers will no longer be available from
1250 python.org as of 2.7.8, it will still be possible to build from
1251 source on 10.3.9 and 10.4 systems if necessary.
1252 See Mac/BuildScript/README.txt for more information.

2634 32-bit-only installer Pythons on systems with Xcode 4 (currently
2635 OS X 10.8, 10.7, and optionally 10.6).
2636 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2637 * Since Xcode 4 removes ppc support, extension module builds now
2638 check for ppc compiler support and by default remove ppc and
2639 ppc64 archs when they are not available.
2640 * Extension module builds now revert to using system installed
2641 headers and libs (/usr and /System/Library) if the SDK used
2642 to build the interpreter is not installed or has moved.
2643 * Try to avoid building extension modules with deprecated
2644 and problematic Apple llvm-gcc compiler. If original compiler
2645 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01003009- Issue #12973: Fix overflow checks that invoked undefined behaviour in
3010 int.__pow__. These overflow checks were causing int.__pow__ to produce
3011 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01003012 compiler optimizing the check away. Also fix similar overflow checks
3013 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
3014 bugs caused test failures with recent versions of Clang.

Florent Xiclunac2279652012-02-12 14:49:03 +01003082- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01003083 has left two versions of customize_compiler, the original in
3084 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01003089- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
3090 Distutils-based packages with C extension modules may fail because
3091 Apple has removed gcc-4.2, the version used to build python.org
3092 64-bit/32-bit Pythons. If the user does not explicitly override
3093 the default C compiler by setting the CC environment variable,
3094 Distutils will now attempt to compile extension modules with clang
3095 if gcc-4.2 is required but not found. Also as a convenience, if
3096 the user does explicitly set CC, substitute its value as the default
3097 compiler in the Distutils LDSHARED configuration variable for OS X.
3098 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
3099 SDK, neither of which are available in Xcode 4. This change does not
3100 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003350- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3351 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3352 interpreter process. This could cause failures in non-Distutils subprocesses
3353 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003354 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003355 deployment target only in the environment of each build subprocess. It is
3356 still possible to globally override the default by setting
3357 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3358 greater or equal to the default value, the value with which the interpreter
3359 was built.

3389 the ticker doesn't have to wind down to zero from the old starting point
3390 before the new interval takes effect. And if the user increases the
3391 interval, it makes sure the new limit takes effect right away rather have an
3392 early task switch before recognizing the new interval.

4390 This prevents user-created self-referencing ordered dictionaries from
4391 becoming permanently uncollectable GC garbage. The downside is that
4392 removing __del__ means that the internal doubly-linked list has to wait for
4393 GC collection rather than freeing memory immediately when the refcnt drops
4394 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004852- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4853 start byte and the continuation byte(s) are now considered invalid, instead
4854 of the number of bytes specified by the start byte.
4855 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4856 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4857 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004866- Issue #8748: Fix two issues with comparisons between complex and integer
4867 objects. (1) The comparison could incorrectly return True in some cases
4868 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4869 (2) The comparison raised an OverflowError for large integers, leading

Georg Brandlfee0f442010-05-22 21:26:21 +00005010- Issue #1533: Fix inconsistency in range function argument processing: any
5011 non-float non-integer argument is now converted to an integer (if possible)
5012 using its __int__ method. Previously, only small arguments were treated this
5013 way; larger arguments (those whose __int__ was outside the range of a C long)
5014 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00005022 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable

Georg Brandlfee0f442010-05-22 21:26:21 +00005064- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
5065 operation raises multiple signals and more than one of those signals is
5066 trapped, the specification determines the order in which the signals should be
5067 handled. In many cases this order wasn't being followed, leading to the wrong
5068 Python exception being raised.

Georg Brandlfee0f442010-05-22 21:26:21 +00005253- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
5254 with a non-empty format string. This is an effort to future-proof user
5255 code. If a derived class does not currently implement __format__ but later
5256 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00005257 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00005258 Python 3.3 and it will be an error in Python 3.4.

5848-----------------
5849
Georg Brandlba83f822010-03-14 09:50:54 +00005850- The ``__complex__()`` method is now looked up on the class of instances to
5851 make it consistent with other special methods.

5855
Mark Dickinson1b34d252010-01-01 17:27:30 +00005856- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005857 DeprecationWarning when passed a float argument where an integer was expected.
5858 These functions and methods now raise TypeError instead. The majority of the
5859 effects of this change are in the extension modules, but some core functions
5860 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5861 and many unicode/str methods.

5873
Georg Brandlba83f822010-03-14 09:50:54 +00005874- Issue #1811: Improve accuracy and cross-platform consistency for true division
5875 of integers: the result of a/b is now correctly rounded for ints a and b (at
5876 least on IEEE 754 platforms), and in particular does not depend on the
5877 internal representation of a long.

5885
Georg Brandlba83f822010-03-14 09:50:54 +00005886 These executables now work properly with the arch(1) command: ``arch -ppc
5887 python`` will start a universal binary version of python in PPC mode (unlike

6027 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00006028
Georg Brandlba83f822010-03-14 09:50:54 +00006029- Remove switch from "%f" formatting to "%g" formatting for floats larger than
6030 1e50 in absolute value.

Georg Brandlba83f822010-03-14 09:50:54 +00006043- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
6044 decimal string that's guaranteed to round back to x under correct rounding
6045 (with round-half-to-even rounding mode). Previously it gave a string based on
6046 rounding x to 17 decimal digits. repr(x) for a complex number behaves
6047 similarly. On platforms where the correctly-rounded strtod and dtoa code is
6048 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006049
Georg Brandlba83f822010-03-14 09:50:54 +00006050- Issue #7117: On almost all platforms: float-to-string and string-to-float
6051 conversions within Python are now correctly rounded. Places these conversions
6052 occur include: str for floats and complex numbers; the float and complex
6053 constructors; old-style and new-style numeric formatting; serialization and
6054 deserialization of floats and complex numbers using marshal, pickle and json;
6055 parsing of float and imaginary literals in Python code; Decimal-to-float
6056 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006057
Georg Brandlba83f822010-03-14 09:50:54 +00006058 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
6059 providing correctly-rounded strtod and dtoa C functions. This code is
6060 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
6061 the C compiler. There may be a small number of platforms on which correct
6062 operation of this code cannot be guaranteed, so the code is not used: notably,
6063 this applies to platforms where the C double format is not IEEE 754 binary64,
6064 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
6065 and Python's configure script is unable to determine how to change the FPU
6066 precision. On these platforms conversions use the platform strtod and dtoa,
6067 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00006069- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
6070 uses the correctly-rounded string <-> float conversions described above (when
6071 available), and so produces correctly rounded results that will display nicely
6072 under the float repr. There are two related small changes: (1) round now
6073 accepts any class with an ``__index__()`` method for its second argument (but
6074 no longer accepts floats for the second argument), and (2) an excessively
6075 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
6076 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00006218
Georg Brandlba83f822010-03-14 09:50:54 +00006219 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
6220 (2) parsing of strings representing infinities and nans was locale aware; and
6221 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00006222
Georg Brandlba83f822010-03-14 09:50:54 +00006223- Issue #5920: For ``float.__format__()``, change the behavior with the empty
6224 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
6225 but with at least one decimal point and with a default precision
6226 of 12. Previously, the behavior the same but with a default precision of 6.
6227 This more closely matches ``str()``, and reduces surprises when adding
6228 alignment flags to the empty presentation type. This also affects the new
6229 complex.__format__ in the same way.
6230
6231- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
6232 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00006294 untrackable objects are not tracked by the garbage collector. This can reduce

6303 internal representation of integers, for performance reasons. Base 2**30 is
6304 enabled by default on 64-bit machines. Add --enable-big-digits option to
6305 configure, which overrides the default. Add sys.long_info structseq to

Georg Brandlba83f822010-03-14 09:50:54 +00006412- Issue #4445: Replace ``sizeof(PyStringObject)`` with
6413 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
6414 instances. On a typical machine this saves 3 bytes of memory (on average) per
6415 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00006417- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

6419 instead of throwing a MemoryError.
6420
Georg Brandlba83f822010-03-14 09:50:54 +00006421- Issue #3689: The list reversed iterator now supports __length_hint__ instead

Benjamin Petersonc078f922008-11-21 22:27:24 +00006424- Issue #4367: Python would segfault during compiling when the unicodedata

6426
Georg Brandlba83f822010-03-14 09:50:54 +00006427- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
6428 file objects with closefd=False. The file descriptor is still kept open but
6429 the file object behaves like a closed file. The ``FileIO`` object also got a
6430 new readonly attribute ``closefd``.

Benjamin Peterson46cc6d12008-11-19 21:49:09 +00006432- Issue #4348: Some bytearray methods returned that didn't cause any change to

6449
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00006450- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00006453- On windows, ``os.chdir()`` given unicode was not working if
6454 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
6455 this code path is really executed because I cannot move to such directory on
6456 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00006457
Georg Brandlba83f822010-03-14 09:50:54 +00006458- Issue #4069: When ``set.remove(element)`` is used with a set element, the
6459 element is temporarily replaced with an equivalent frozenset. But the
6460 eventual KeyError would always report the empty ``frozenset()`` as the missing
6461 key. Now it correctly refers to the initial element.

6479 returned them on 64bit platforms.
6480
Walter Dörwalded960ac2009-05-03 22:36:33 +00006481- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
6482 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6483 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6484 of using the replace error handler in PyUnicode_DecodeUTF8().
6485
Walter Dörwald726ba8e2009-05-06 14:32:35 +00006486- Issue #3739: The unicode-internal encoder now reports the number of characters
6487 consumed like any other encoder (instead of the number of bytes).
6488
Georg Brandlba83f822010-03-14 09:50:54 +00006489- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
6490 allocator will be automatically disabled when running under Valgrind. This
6491 gives improved memory leak detection when running under Valgrind, while taking
6492 advantage of pymalloc at other times.

7780 support, which does the conversion.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007883- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7884 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7885 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7886 ``printf`` function, whereas PyString_FromFormat has an independent
7887 implementation and uses "%zd" on all platforms for size_t values.
7888 This makes a difference on win64, where ``printf`` needs "%Id" to display
7889 64bit values.

Vinay Sajip35e3b032008-09-01 14:33:59 +00007908- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007909 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7910 mechanism. In the process, fix a bug where isinstance() and issubclass(),

7912 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7913 type object.

8058-----------------
8059
Guido van Rossumf8402962008-08-20 15:01:50 +00008060- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
8061 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
8062 extensions do not automatically benefit from the class attribute
8063 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
8064 to their tp_flags field if they care. This is a backwards
8065 compatibility feature; in 3.0, all types will use the cache by
8066 default.
8067
Benjamin Petersonf647dc12008-08-20 01:27:30 +00008068- Keyword arguments can now follow starred arguments. (``f(a, *args,

Mark Dickinsonb6467572008-08-04 21:30:09 +00008081- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
8082 ValueError consistently across platforms.
8083
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00008084- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
8085 (64bit Unix, for example), unichr() would truncate its argument and return
8086 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
8087
Neal Norwitze7d8be82008-07-31 17:17:14 +00008088- Apply security patches from Apple.

Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00008090- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
8091 PyErr_ExceptionMatches returns 0 when an exception occurs there.
8092
Antoine Pitrou92f82162008-07-25 22:22:08 +00008093- Issue #1819: function calls with several named parameters are now on
8094 average 35% faster (as measured by pybench).
8095
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00008096- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
8097 the python debugger steps into a class statement: the free variables (local
8098 variables defined in an outer scope) would be deleted from the outer scope.
8099
Gregory P. Smith0470bab2008-07-22 04:46:32 +00008100- Issue #2620: Overflow checking when allocating or reallocating memory
8101 was not always being done properly in some python types and extension
8102 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
8103 all been updated to perform better checks and places in the code that
8104 would previously leak memory on the error path when such an allocation
8105 failed have been fixed.

8113 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
8114
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00008115- Issue #2234: distutils failed for some versions of the cygwin compiler. The
8116 version reported by these tools does not necessarily follow the python
8117 version numbering scheme, so the module is less strict when parsing it.
8118
Nick Coghlanf70385a2008-08-18 12:42:46 +00008119- Issue #2235: Added Py3k warnings for types which will become unhashable
8120 under the stricter __hash__ inheritance rules in 3.0. Several types
8121 which did not meet the rules for hash invariants and were already
8122 unhashable in 3.0 have now been explicitly flagged as unhashable in
8123 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
8124 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
8125
Brett Cannon88f801d2008-08-18 00:46:22 +00008126- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

Brett Cannonbf3157b2008-08-14 05:00:03 +00008157- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
8158 since mimetools itself is deprecated. Because modules are cached, all
8159 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
8160

8173 to _sre.compile() will now be rejected. This should not affect anybody
8174 since the re.compile() function never generates invalid re-bytecode.
8175
Skip Montanaroa032bf42008-08-08 22:52:51 +00008176- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

8178 it wasn't initialized during instantiation.
8179
Brett Cannon3aa2a492008-08-06 22:28:09 +00008180- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
8181 the reload() built-in has been removed.
8182
Brett Cannon7e30b672008-08-04 21:52:25 +00008183- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00008184 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00008195 asking for a specific length. This problem only affected files opened
8196 using the new "io" module, not the built-in open() function.

8222 file name rather than a ZipInfo instance, so files are extracted with
8223 mode 0600 rather than 000 under Unix.
8224
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00008225- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
8226 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00008237- Issue #2235: the C API function PyObject_HashNotImplemented and its
8238 interaction with the tp_hash slot (added in 2.6b2) are now documented
8239
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00008240- Issue #643841: The language reference now provides more detailed
8241 coverage of the lookup process for special methods. The disclaimers
8242 regarding lack of coverage of new-style classes have also been
8243 removed, since the coverage is now fairly reasonable.

8247================================
8248
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00008249*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00008251Core and Builtins
8252-----------------
8253
Georg Brandl3e483f62008-07-16 22:57:41 +00008254- Issue #3156: Fix inconsistent behavior of the bytearray type: all
8255 its methods now allow for items objects that can be converted to
8256 an integer using operator.index().
8257
Mark Dickinson64b7e502008-07-16 09:40:03 +00008258- Issue #3360: Fix incorrect parsing of '020000000000.0', which
8259 produced a ValueError instead of giving the correct float.
8260
Eric Smitha5fa5a22008-07-16 00:11:49 +00008261- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
8262 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
8263
Mark Dickinson7103aa42008-07-15 19:08:33 +00008264- Issue #3008: the float type has a new instance method 'float.hex'
8265 and a new class method 'float.fromhex' to convert floating-point
8266 numbers to and from hexadecimal strings, respectively.
8267
Nick Coghlan6d6bd442008-07-15 15:40:22 +00008268- Issue #2235: __hash__ is once again inherited by default. To allow
8269 collections.Hashable to remain meaningful in the presence of the
8270 default hash implementation (object.__hash__), it is now possible
8271 to explicit block inheritance of hash by setting __hash__=None at
8272 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8273 level.
8274
Nick Coghlanb028f502008-07-13 14:52:36 +00008275- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8276 the parent module cannot be found while performing an absolute import.
8277 This means that an incorrectly defined __package__ attribute will
8278 now only prevent relative imports in that module rather than causing
8279 all imports from that module to fail.
8280
Nick Coghlan14ff9942008-07-08 14:21:42 +00008281- Issue #2517: Allow unicode messages in Exceptions again by correctly
8282 bypassing the instance dictionary when looking up __unicode__ on
8283 new-style classes.
8284
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00008285- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
8286 set to a custom object whose write() method happens to install
8287 another file in sys.stdout.
8288
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00008289- Issue #3088: Corrected a race condition in classes derived from
8290 threading.local: the first member set by a thread could be saved in
8291 another thread's dictionary.
8292
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008293- Issue #3004: Minor change to slice.indices(): the start and stop
8294 arguments are now treated identically, making the behaviour easier
8295 to describe and understand. For example, slice(None, -10,
8296 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8297 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8298 10, -1).
8299
Georg Brandl278fc502008-07-19 12:46:12 +00008300- Issue #3219: Calling a function with repeated keyword arguments,
8301 f(a=2, a=23), would not cause a syntax error. This was a regression
8302 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00008303
Georg Brandl278fc502008-07-19 12:46:12 +00008304- Issue #2862: Make int and float freelist management consistent with
8305 other freelists. Changes their CompactFreeList apis into
8306 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00008307

8310
Thomas Heller57adf222008-08-14 19:10:48 +00008311- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
8312 api functions without holding the GIL, which could lead to a fatal
8313 error when they failed.
8314
Martin v. Löwisaabf4042008-08-02 07:20:25 +00008315- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

8324 ForkingPickler.register() to resolve conflict with ctypes.
8325
Vinay Sajip51e65192008-07-18 09:01:10 +00008326- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00008327
Thomas Heller880f5292008-07-15 19:39:38 +00008328- Issue #3313: Fixed a crash when a failed dlopen() call does not set
8329 a valid dlerror() message.
8330
Thomas Heller2bad6572008-07-15 17:19:50 +00008331- Issue #3258: Fixed a crash when a ctypes POINTER type to an
8332 incomplete structure was created.
8333
Brett Cannon3d0b9f02008-07-13 01:15:07 +00008334- Issue #3339: dummy_thread.acquire() should not return None.

8337
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008338- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00008339
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008340- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
8341 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008342 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008343 content-length. The problem had been corrected in the 2.4 branch, but never
8344 merged into trunk.
8345
Georg Brandle78fbcc2008-07-05 10:13:36 +00008346- Issue #2663: add filtering capability to shutil.copytree().

Georg Brandl5cc774e2008-06-11 20:28:06 +00008750 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008751
8752 This is controlled by the configure argument ``--with-universal-archs``:
8753
8754 - ``--with-universal-archs=all``: install 4-way universal
8755
8756 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8757
8758 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8759
8760 This option should be used in combination with ``--enable-universalsdk=``.
8761
8762 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 +00008811- Issue #1631171: Re-implement the 'warnings' module in C (the
8812 original Python code has been kept as backup). This will allow for
8813 using the 'warning's machinery in such places as the parser where
8814 use of pure Python code is not possible. Both the ``showarning()``
8815 and ``formatwarning()`` gain an optional 'line' argument which is
8816 not called by default for backwards-compatibility reasons. Setting
8817 ``warnings.showwarning()`` to an implementation that lacks support
8818 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008881- Issue #2550: The approach used by client/server code for obtaining
8882 ports to listen on in network-oriented tests has been refined in an
8883 effort to facilitate running multiple instances of the entire
8884 regression test suite in parallel without issue.
8885 test_support.bind_port() has been fixed such that it will always
8886 return a unique port -- which wasn't always the case with the
8887 previous implementation, especially if socket options had been set
8888 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8889 new implementation of bind_port() will actually raise an exception
8890 if it is passed an AF_INET/SOCK_STREAM socket with either the
8891 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8892 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8893 the socket it's been passed. This currently only applies to
8894 Windows. This option prevents any other sockets from binding to the
8895 host/port we've bound to, thus removing the possibility of the
8896 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8897 when a second SOCK_STREAM socket binds and accepts to a host/port
8898 that's already been bound by another socket. The optional preferred
8899 port parameter to bind_port() has been removed. Under no
8900 circumstances should tests be hard coding ports!
8901
8902 test_support.find_unused_port() has also been introduced, which will
8903 pass a temporary socket object to bind_port() in order to obtain an
8904 unused port. The temporary socket object is then closed and
8905 deleted, and the port is returned. This method should only be used
8906 for obtaining an unused port in order to pass to an external program
8907 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8908 a parameter to a server-oriented class that doesn't give you direct
8909 access to the underlying socket used.
8910
8911 Finally, test_support.HOST has been introduced, which should be used
8912 for the host argument of any relevant socket calls (i.e. bind and
8913 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008914

9187Core and builtins
9188-----------------
9189
Fred Drakea8ee94b2008-03-01 02:45:07 +00009190- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00009191 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00009192
Georg Brandlad61bc82008-02-23 15:11:18 +00009193- Issue #2067: file.__exit__() now calls subclasses' close() method.
9194
9195- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00009196
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009197- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00009198 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00009199
Eric Smitha73fbe72008-02-23 03:09:44 +00009200- Added the future_builtins module, which contains hex() and oct().
9201 These are the PEP 3127 version of these functions, designed to be
9202 compatible with the hex() and oct() builtins from Python 3.0. They
9203 differ slightly in their output formats from the existing, unchanged
9204 Python 2.6 builtins. The expected usage of the future_builtins
9205 module is:
9206 from future_builtins import hex, oct
9207
Eric Smith7ef40bf2008-02-20 23:34:22 +00009208- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
9209 exponents for exponents with absolute value < 100. Follows C99
9210 standard. This is a change on Windows, which would use 3 digits.
9211 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
9212 so that any alterations it does to the resulting string will be
9213 available in stringlib/formatter.h (for float.__format__).
9214
Eric Smith5a3c1352008-02-19 13:21:56 +00009215- Implemented PEP 3101, Advanced String Formatting. This adds a new
9216 builtin format(); a format() method for str and unicode; a
9217 __format__() method to object, str, unicode, int, long, float, and
9218 datetime; the class string.Formatter; and the C API
9219 PyObject_Format().
9220
Georg Brandl3ee81df2008-05-17 18:14:43 +00009221- Fixed several potential crashes, all caused by specially crafted
9222 __del__ methods exploiting objects in temporarily inconsistent
9223 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00009224
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009225- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00009226 prevent a possible crash: an Abstract Base Class would try to access
9227 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00009228
Georg Brandl3ee81df2008-05-17 18:14:43 +00009229- Fixed repr() and str() of complex numbers with infinity or nan as
9230 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00009231
Georg Brandl3ee81df2008-05-17 18:14:43 +00009232- Clear all free lists during a gc.collect() of the highest generation
9233 in order to allow pymalloc to free more arenas. Python may give back
9234 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00009235
Georg Brandl3ee81df2008-05-17 18:14:43 +00009236- Issue #2045: Fix an infinite recursion triggered when printing a
9237 subclass of collections.defaultdict, if its default_factory is set
9238 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00009239
Christian Heimesf75dbef2008-02-08 00:11:31 +00009240- Fixed a minor memory leak in dictobject.c. The content of the free
9241 list was not freed on interpreter shutdown.
9242
Georg Brandl21e99f42010-03-07 15:23:59 +00009243- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00009244 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00009245
Georg Brandl3ee81df2008-05-17 18:14:43 +00009246- Patch #1953: Added ``sys._compact_freelists()`` and the C API
9247 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00009248 to compact the internal free lists of pre-allocted ints and floats.
9249
Georg Brandl3ee81df2008-05-17 18:14:43 +00009250- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
9251 calls. Python expected the return type int but the fork familie
9252 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00009253
Georg Brandl3ee81df2008-05-17 18:14:43 +00009254- Issue #1678380: Fix a bug that identifies 0j and -0j when they
9255 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00009256
Georg Brandl3ee81df2008-05-17 18:14:43 +00009257- Issue #2025: Add tuple.count() and tuple.index() methods to comply
9258 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00009259
Georg Brandl3ee81df2008-05-17 18:14:43 +00009260- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
9261 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00009262
Georg Brandl3ee81df2008-05-17 18:14:43 +00009263- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
9264 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00009265
Georg Brandl3ee81df2008-05-17 18:14:43 +00009266- Patch #1473257: generator objects gain a gi_code attribute. This is
9267 the same object as the func_code attribute of the function that
9268 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00009269
Georg Brandl3ee81df2008-05-17 18:14:43 +00009270- Issue #1920: "while 0" statements were completely removed by the
9271 compiler, even in the presence of an "else" clause, which is
9272 supposed to be run when the condition is false. Now the compiler
9273 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009274
Guido van Rossumeead05f2008-01-24 18:21:02 +00009275- A few crashers fixed: weakref_in_del.py (issue #1377858);
9276 loosing_dict_ref.py (issue #1303614, test67.py);
9277 borrowed_ref_[34].py (not in tracker).
9278
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00009279- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00009280 suppressed while an extension is loaded by calling SetErrorMode in
9281 dynload_win.c. The error is still reported properly.
9282
Georg Brandl3ee81df2008-05-17 18:14:43 +00009283- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009284 several extension methods and modules do not work without unicode
9285 support.
9286
Georg Brandl26543b12008-01-21 18:36:51 +00009287- Issue #1882: when compiling code from a string, encoding cookies in the
9288 second line of code were not always recognized correctly.
9289
Georg Brandl14404b62008-01-19 19:27:05 +00009290- Issue #1679: "0x" was taken as a valid integer literal.
9291
Georg Brandl6caad7d2008-01-26 14:19:22 +00009292- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009293 added.
9294
Christian Heimesc94e2b52008-01-14 04:13:37 +00009295- sys.float_info / PyFloat_GetInfo: The floating point information
9296 object was converted from a dict to a specialized structseq object.
9297
Georg Brandl3ee81df2008-05-17 18:14:43 +00009298- Patch #1816: Added sys.flags structseq. It exposes the status of
9299 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009300
Georg Brandl3ee81df2008-05-17 18:14:43 +00009301- Objects/structseq.c: Implemented new structseq representation. The
9302 patch makes structseqs (e.g. the return value of os.stat) more
9303 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009304
Georg Brandl3ee81df2008-05-17 18:14:43 +00009305- Patch #1700288: added a type attribute cache that caches method
9306 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00009307
Neal Norwitz3fc15b82008-01-10 05:42:58 +00009308- Bug #1776: __import__() no longer accepts filenames on any platform.
9309 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00009310
Georg Brandlaed6c662008-01-07 17:25:53 +00009311- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
9312
Georg Brandl3ee81df2008-05-17 18:14:43 +00009313- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
9314 envvar and sys.dont_write_bytecode attribute. All these can be set
9315 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00009316
Georg Brandl3ee81df2008-05-17 18:14:43 +00009317- Improve some exception messages when Windows fails to load an
9318 extension module. Now we get for example '%1 is not a valid Win32
9319 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00009320
Georg Brandl3ee81df2008-05-17 18:14:43 +00009321- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009323- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
9324 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00009325
Christian Heimes0a8143f2007-12-18 23:22:54 +00009326- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00009327 and INF. float("nan"), float("inf") and float("-inf") now work on
9328 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009329
Georg Brandl3ee81df2008-05-17 18:14:43 +00009330- Compiler now generates simpler and faster code for dictionary
9331 literals. The oparg for BUILD_MAP now indicates an estimated
9332 dictionary size. There is a new opcode, STORE_MAP, for adding
9333 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00009334
Georg Brandl3ee81df2008-05-17 18:14:43 +00009335- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00009336
Georg Brandl3ee81df2008-05-17 18:14:43 +00009337- Issue #1620: New property decorator syntax was modifying the
9338 decorator in place instead of creating a new decorator object.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009340- Issue #1538: Avoid copying string in split/rsplit if the split char
9341 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00009342
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00009343- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00009344 SystemError.
9345
Nick Coghlanef01d822007-12-03 12:55:17 +00009346- PEP 366: Allow explicit relative imports when executing modules
9347 inside packages with the -m switch via a new module level
9348 __package__ attribute.
9349
Georg Brandl3ee81df2008-05-17 18:14:43 +00009350- Issue #1402: Fix a crash on exit, when another thread is still
9351 running, and if the deallocation of its frames somehow calls the
9352 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00009353

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00009357 attribute of an empty cell object.
9358
Georg Brandl3ee81df2008-05-17 18:14:43 +00009359- Issue #1460: The utf-7 incremental decoder did not accept truncated
9360 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00009361
Georg Brandl3ee81df2008-05-17 18:14:43 +00009362- Patch #1739468: Directories and zipfiles containing a __main__.py
9363 file can now be directly executed by passing their name to the
9364 interpreter. The directory/zipfile is automatically inserted as the
9365 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00009366
Georg Brandl3ee81df2008-05-17 18:14:43 +00009367- Issue #1265: Fix a problem with sys.settrace, if the tracing
9368 function uses a generator expression when at the same time the
9369 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00009370
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00009371- sets and frozensets now have an isdisjoint() method.
9372
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00009373- optimize the performance of builtin.sum().
9374
Neal Norwitz44f326e2007-10-05 05:29:17 +00009375- Fix warnings found by the new version of the Coverity checker.
9376
Georg Brandl21e99f42010-03-07 15:23:59 +00009377- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009378 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9379 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009380
Georg Brandl3ee81df2008-05-17 18:14:43 +00009381- Issue #1686386: Tuple's tp_repr did not take into account the
9382 possibility of having a self-referential tuple, which is possible
9383 from C code. Nor did object's tp_str consider that a type's tp_str
9384 could do something that could lead to an inifinite recursion.
9385 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9386 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009387
Georg Brandl3ee81df2008-05-17 18:14:43 +00009388- Issue #1164: It was possible to trigger deadlock when using the
9389 'print' statement to write to a file since the GIL was not released
9390 as needed. Now PyObject_Print() does the right thing along with
9391 various tp_print implementations of the built-in types and those in
9392 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009393
Georg Brandl3ee81df2008-05-17 18:14:43 +00009394- Issue #1147: Exceptions were directly allowing string exceptions in
9395 their throw() method even though string exceptions no longer
9396 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00009397
Georg Brandl3ee81df2008-05-17 18:14:43 +00009398- Issue #1096: Prevent a segfault from getting the repr of a very
9399 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00009400
Brett Cannon1e534b52007-09-07 04:18:30 +00009401- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009402 PyObject_Call() never calling back out to Python code to trigger
9403 recursion depth updates/checks. Required the creation of a static
9404 RuntimeError instance in case normalizing an exception put the
9405 recursion check value past its limit. Fixes crashers
9406 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00009407

Neal Norwitz0ac60192007-05-27 04:08:54 +00009421- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00009422 __*__ attributes. (Some already existed, e.g., __doc__ and
9423 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00009424
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00009425- Add -3 option to the interpreter to warn about features that are

9430
Collin Winter62903052007-05-18 23:11:24 +00009431- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009432 "except E as target:". This is to provide forwards compatibility
9433 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00009434
Brett Cannon229cee22007-05-05 01:34:02 +00009435- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00009440- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009441 setting a plain string, ie don't expand to single letter identifiers.
9442
Raymond Hettinger13936692007-04-11 18:40:58 +00009443- Request #1191699: Slices can now be pickled.
9444
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00009445- Request #1193128: str.translate() now allows a None argument for

9453
Guido van Rossum143b5642007-03-23 04:58:42 +00009454- Bug #1683368: The object.__init__() and object.__new__() methods are
9455 now stricter in rejecting excess arguments. The only time when
9456 either allows excess arguments is when it is not overridden and the
9457 other one is. For backwards compatibility, when both are
9458 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009459 warning later). Also, type.__init__() insists on the same signature
9460 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00009461
Georg Brandl3ee81df2008-05-17 18:14:43 +00009462- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9463 object to complex using its __complex__() method before falling back
9464 to the __float__() method. Therefore, the functions in the cmath
9465 module now can operate on objects that define a __complex__()
9466 method.
Georg Brandl2b869942007-03-17 16:08:45 +00009467

9469 __slots__. The old and the new class are still required to have the
9470 same slot names.

9483
Georg Brandl7b9c5552007-03-12 14:30:05 +00009484- Bug #1678647: write a newline after printing an exception in any
9485 case, even when converting the value to a string failed.
9486
Georg Brandl871f1bc2007-03-12 13:17:36 +00009487- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009488 its argument, if it exists. If not, it will work like before. This
9489 allows customizing the output of dir() in the presence of a
9490 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00009491
Collin Winter276887b2007-03-12 16:11:39 +00009492- Patch #922167: Python no longer segfaults when faced with infinitely
9493 self-recursive reload() calls (as reported by bug #742342).

9499 parthensized forms. This means complex(repr(x)) now works instead of
9500 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00009501
Georg Brandlaa2321b2007-03-07 00:40:28 +00009502- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009503 makes the filenames the warning module prints much more sensible
9504 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00009505

Georg Brandl0fca97a2007-03-05 22:28:08 +00009517- Patch #1674228: when assigning a slice (old-style), check for the
9518 sq_ass_slice instead of the sq_slice slot.
9519
Georg Brandl3ee81df2008-05-17 18:14:43 +00009520- When printing an unraisable error, don't print exceptions. before

10144
Georg Brandl3ee81df2008-05-17 18:14:43 +000010145- unittest now verifies more of its assumptions. In particular,
10146 TestCase and TestSuite subclasses (not instances) are no longer
10147 accepted in TestSuite.addTest(). This should cause no
10148 incompatibility since it never made sense with ordinary subclasses
10149 -- the failure just occurred later, with a more cumbersome
10150 exception.

10419 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +000010420
Georg Brandl3ee81df2008-05-17 18:14:43 +000010421- The implementation of UnicodeError objects has been simplified

Georg Brandl3ee81df2008-05-17 18:14:43 +000010430- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +000010431 that the SMTP.starttls() caller no longer needs to call ehlo()
10432 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +000010433 does not claim to support starttls. Adds the
10434 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +000010477- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +000010478 works as expected. ``mmap.find`` also takes an optional ``end``

10515 complex, tuple, list, dict, set, and frozenset. Formerly, it would
10516 silently miscode subclasses of those types. Now, it raises a
10517 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +000010518

Georg Brandl3ee81df2008-05-17 18:14:43 +000010533 time so that opening a database previously created with the DB_DUP
10534 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10535 opens. Specifically: dictionary assignment to a DB object will
10536 replace all values for a given key when the database allows
10537 duplicate values. DB users should use DB.put(k, v) when they want
10538 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010539

10545 characters with ASCII value less than 32. Also, it correctly quotes
10546 dots only if they occur on a single line, as opposed to the previous
10547 behavior of quoting dots if they are the second character of any
10548 line.
Georg Brandl4aef7272007-03-13 22:49:43 +000010549

10877
Georg Brandl3ee81df2008-05-17 18:14:43 +000010878- Unified naming convention for free lists and their limits. All free
10879 lists in Object/ are named ``free_list``, the counter ``numfree``
10880 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
10881 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +000010882
Georg Brandl3ee81df2008-05-17 18:14:43 +000010883- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
10884 to ``PyTuple_SetItem``, it can be used to populate a brand new
10885 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +000010886
Vinay Sajipb7edfc42008-04-02 21:10:23 +000010887- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

10890 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
10891 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010892
10893- Patch #1720595: add T_BOOL to the range of structmember types.
10894
10895- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
10896 ``PyFloat_GetInfo()`` to the float API.
10897
Georg Brandl3ee81df2008-05-17 18:14:43 +000010898- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
10899 of w# format code incorrectly truncated the length to an int, even
10900 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10901 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010902
Georg Brandl3ee81df2008-05-17 18:14:43 +000010903- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
10904 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010906- PEP 3123: Provide forward compatibility with Python 3.0, while
10907 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
10908 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010909
Georg Brandl3ee81df2008-05-17 18:14:43 +000010910- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
10911 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010912
10913- Patch #1733960: Allow T_LONGLONG to accept ints.

10920
10921- Fix some leftovers from the conversion from int to Py_ssize_t
10922 (relevant to strings and sequences of more than 2**31 items).
10923
10924- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10925 outside of pystate.c and should not be necessary.
10926
Georg Brandl3ee81df2008-05-17 18:14:43 +000010927- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10928 absolute imports. In earlier versions they might have used relative
10929 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010930
Georg Brandl3ee81df2008-05-17 18:14:43 +000010931- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10932 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010933
Georg Brandl3ee81df2008-05-17 18:14:43 +000010934- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +000010940- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10941 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10942 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10943 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010944
Georg Brandl3ee81df2008-05-17 18:14:43 +000010945- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +000010957- Removed the macfs module. It had been deprecated since Python 2.5.
10958 This lead to the deprecation of macostools.touched() as it relied
10959 solely on macfs and was a no-op under OS X.
