Ned Deily18fae3f2013-01-31 01:24:55 -0800807- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
808 In particular, fix extension module build failures when trying to use
809 32-bit-only installer Pythons on systems with Xcode 4 (currently
810 OS X 10.8, 10.7, and optionally 10.6).
811 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
812 * Since Xcode 4 removes ppc support, extension module builds now
813 check for ppc compiler support and by default remove ppc and
814 ppc64 archs when they are not available.
815 * Extension module builds now revert to using system installed
816 headers and libs (/usr and /System/Library) if the SDK used
817 to build the interpreter is not installed or has moved.
818 * Try to avoid building extension modules with deprecated
819 and problematic Apple llvm-gcc compiler. If original compiler
820 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01001177- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001178 has left two versions of customize_compiler, the original in
1179 distutils.sysconfig and another copy in distutils.ccompiler, with some
1180 parts of distutils calling one and others using the other.
1181 Complete the revert back to only having one in distutils.sysconfig as
1182 is the case in 3.x.
1183
Ned Deily0d0ea482012-02-10 12:59:06 +01001184- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1185 Distutils-based packages with C extension modules may fail because
1186 Apple has removed gcc-4.2, the version used to build python.org
1187 64-bit/32-bit Pythons. If the user does not explicitly override
1188 the default C compiler by setting the CC environment variable,
1189 Distutils will now attempt to compile extension modules with clang
1190 if gcc-4.2 is required but not found. Also as a convenience, if
1191 the user does explicitly set CC, substitute its value as the default
1192 compiler in the Distutils LDSHARED configuration variable for OS X.
1193 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1194 SDK, neither of which are available in Xcode 4. This change does not
1195 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001468- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1469 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1470 interpreter process. This could cause failures in non-Distutils subprocesses
1471 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001472 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001473 deployment target only in the environment of each build subprocess. It is
1474 still possible to globally override the default by setting
1475 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1476 greater or equal to the default value, the value with which the interpreter
1477 was built.

1507 the ticker doesn't have to wind down to zero from the old starting point
1508 before the new interval takes effect. And if the user increases the
1509 interval, it makes sure the new limit takes effect right away rather have an
1510 early task switch before recognizing the new interval.

2923-----------------
2924
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002925- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2926 start byte and the continuation byte(s) are now considered invalid, instead
2927 of the number of bytes specified by the start byte.
2928 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2929 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2930 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2931 Previous versions returned a single u'\ufffd'.

2935 arises from the "Overriding __eq__ blocks inheritance ..." warning
2936 when turned into an exception: in this case the exception simply
2937 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002939- Issue #8748: Fix two issues with comparisons between complex and integer
2940 objects. (1) The comparison could incorrectly return True in some cases
2941 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2942 (2) The comparison raised an OverflowError for large integers, leading
2943 to unpredictable exceptions when combining integers and complex objects
2944 in sets or dicts.
2945
Mark Dickinson81336372010-05-30 12:12:25 +00002946- Issue #5211: Implicit coercion for the complex type is now completely
2947 removed. (Coercion for arithmetic operations was already removed in 2.7
2948 alpha 4, but coercion for rich comparisons was accidentally left in.)

3140 handled. In many cases this order wasn't being followed, leading to the wrong
3141 Python exception being raised.

3314 changed.

Georg Brandlfee0f442010-05-22 21:26:21 +00003326- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3327 with a non-empty format string. This is an effort to future-proof user
3328 code. If a derived class does not currently implement __format__ but later
3329 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003330 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003331 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003381- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3382 InvalidOperation instead of returning False. (Comparisons involving a quiet
3383 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3384 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00003386- Issue #2531: Comparison operations between floats and Decimal instances now
3387 return a result based on the numeric values of the operands; previously they
3388 returned an arbitrary result based on the relative ordering of id(float) and
3389 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003391- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003392 argument `-` which tells it to read files to compile from stdin. Each line is
3393 read on demand and the named file is compiled immediately. (Original patch by
3394 Piotr Ożarowski).

3404 Fractions instance now raise TypeError instead of returning True/False. This
3405 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3406 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00003510- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
3511 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the

3515 the set of integer codes for which it was used differed between native packing
3516 and standard packing.)

3845 encoded string for them. This ensures that the upload and register commands
3846 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00003923- The ``__complex__()`` method is now looked up on the class of instances to
3924 make it consistent with other special methods.

3928
Mark Dickinson1b34d252010-01-01 17:27:30 +00003929- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003930 DeprecationWarning when passed a float argument where an integer was expected.
3931 These functions and methods now raise TypeError instead. The majority of the
3932 effects of this change are in the extension modules, but some core functions
3933 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3934 and many unicode/str methods.

3949 least on IEEE 754 platforms), and in particular does not depend on the
3950 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00004096- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
4097 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004098
Georg Brandlba83f822010-03-14 09:50:54 +00004099- Issue #3382: 'F' formatting for float and complex now convert the result to
4100 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
4101 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004102
Georg Brandlba83f822010-03-14 09:50:54 +00004103- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4104 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00004105
Georg Brandlba83f822010-03-14 09:50:54 +00004106- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
4107 1e-100 used to raise OverflowError, but now gives the requested 120
4108 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00004109
Georg Brandlba83f822010-03-14 09:50:54 +00004110- Add Py3k warnings for parameter names in parentheses.

Benjamin Peterson89b1a5c2009-11-19 22:58:01 +00004113
Georg Brandlba83f822010-03-14 09:50:54 +00004114- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
4115 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00004116
Georg Brandlba83f822010-03-14 09:50:54 +00004117- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4118 decimal string that's guaranteed to round back to x under correct rounding
4119 (with round-half-to-even rounding mode). Previously it gave a string based on
4120 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4121 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4122 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004123
Georg Brandlba83f822010-03-14 09:50:54 +00004124- Issue #7117: On almost all platforms: float-to-string and string-to-float
4125 conversions within Python are now correctly rounded. Places these conversions
4126 occur include: str for floats and complex numbers; the float and complex
4127 constructors; old-style and new-style numeric formatting; serialization and
4128 deserialization of floats and complex numbers using marshal, pickle and json;
4129 parsing of float and imaginary literals in Python code; Decimal-to-float
4130 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004131
Georg Brandlba83f822010-03-14 09:50:54 +00004132 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4133 providing correctly-rounded strtod and dtoa C functions. This code is
4134 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4135 the C compiler. There may be a small number of platforms on which correct
4136 operation of this code cannot be guaranteed, so the code is not used: notably,
4137 this applies to platforms where the C double format is not IEEE 754 binary64,
4138 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4139 and Python's configure script is unable to determine how to change the FPU
4140 precision. On these platforms conversions use the platform strtod and dtoa,
4141 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004142
Georg Brandlba83f822010-03-14 09:50:54 +00004143- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4144 uses the correctly-rounded string <-> float conversions described above (when
4145 available), and so produces correctly rounded results that will display nicely
4146 under the float repr. There are two related small changes: (1) round now
4147 accepts any class with an ``__index__()`` method for its second argument (but
4148 no longer accepts floats for the second argument), and (2) an excessively
4149 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4150 raises an exception.

4153
Georg Brandlba83f822010-03-14 09:50:54 +00004154- Fix several issues with ``compile()``. The input can now contain Windows and
4155 Mac newlines and is no longer required to end in a newline.
Benjamin Petersone36199b2009-11-12 23:39:44 +00004156

4186 The tables for code points representing numeric values, white spaces or line
4187 breaks are now generated from the official Unicode Character Database files,
4188 and include information from the Unihan.txt file.

Georg Brandlba83f822010-03-14 09:50:54 +00004297- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4298 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4299 but with at least one decimal point and with a default precision
4300 of 12. Previously, the behavior the same but with a default precision of 6.
4301 This more closely matches ``str()``, and reduces surprises when adding

5934 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5935 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5936 ``printf`` function, whereas PyString_FromFormat has an independent
5937 implementation and uses "%zd" on all platforms for size_t values.
5938 This makes a difference on win64, where ``printf`` needs "%Id" to display
5939 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00005941- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
5942 error.
5943
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00005944- Issue #3777: long() applied to a float object now always return a long
5945 object; previously an int would be returned for small values. the __long__
5946 method is allowed to return either an int or a long, but the behaviour of
5947 float objects should not change to respect backward compatibility.
5948
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005949- Issue #3751: str.rpartition would perform a left-partition when called with
5950 a unicode argument.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005954- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00005955 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005956 was correctly parsed but parsing of subsequent arguments failed.
5957
Vinay Sajip35e3b032008-09-01 14:33:59 +00005958- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005959 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5960 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5961 when given a tuple of classes as second argument, were looking up
5962 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5963 type object.
5964
Neal Norwitz18aa3882008-08-24 05:04:52 +00005965- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006034 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6035 for catch_warnings() also led to an improvement in the raising of a
6036 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006102What's New in Python 2.6 beta 3?
6103================================
6104
Barry Warsaw07a4a382008-08-21 01:15:08 +00006105*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006106
6107Core and Builtins
6108-----------------
6109
Guido van Rossumf8402962008-08-20 15:01:50 +00006110- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6111 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6112 extensions do not automatically benefit from the class attribute
6113 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6114 to their tp_flags field if they care. This is a backwards
6115 compatibility feature; in 3.0, all types will use the cache by
6116 default.
6117
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006118- Keyword arguments can now follow starred arguments. (``f(a, *args,
6119 keyword=23)`` is now valid syntax.)
6120
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006121- ctypes function pointers that are COM methods have a boolean True
6122 value again.
6123
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006124- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6125 by denying s# to parse objects that have a releasebuffer procedure,
6126 and introducing s*.
6127
Georg Brandl1e13ea92008-08-11 09:07:59 +00006128- Issue #3537: Fix an assertion failure when an empty but presized dict
6129 object was stored in the freelist.
6130
Mark Dickinsonb6467572008-08-04 21:30:09 +00006131- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6132 ValueError consistently across platforms.
6133
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006134- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6135 (64bit Unix, for example), unichr() would truncate its argument and return
6136 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6137
Neal Norwitze7d8be82008-07-31 17:17:14 +00006138- Apply security patches from Apple.
6139
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006140- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6141 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6142
Antoine Pitrou92f82162008-07-25 22:22:08 +00006143- Issue #1819: function calls with several named parameters are now on
6144 average 35% faster (as measured by pybench).
6145
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006146- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6147 the python debugger steps into a class statement: the free variables (local
6148 variables defined in an outer scope) would be deleted from the outer scope.
6149
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006150- Issue #2620: Overflow checking when allocating or reallocating memory
6151 was not always being done properly in some python types and extension
6152 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6153 all been updated to perform better checks and places in the code that
6154 would previously leak memory on the error path when such an allocation
6155 failed have been fixed.

6159
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006160- Issue #3612: Added some missing basic types in ctypes.wintypes.
6161
Benjamin Petersone977ad42008-08-20 01:42:01 +00006162- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6163 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6164
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006165- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6166 version reported by these tools does not necessarily follow the python
6167 version numbering scheme, so the module is less strict when parsing it.
6168
Nick Coghlanf70385a2008-08-18 12:42:46 +00006169- Issue #2235: Added Py3k warnings for types which will become unhashable
6170 under the stricter __hash__ inheritance rules in 3.0. Several types
6171 which did not meet the rules for hash invariants and were already
6172 unhashable in 3.0 have now been explicitly flagged as unhashable in
6173 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6174 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6175
Brett Cannon88f801d2008-08-18 00:46:22 +00006176- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

6184
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006185- Issue #3575: Incremental decoder's decode function now takes bytearray
6186 by using 's*' instead of 't#'.
6187
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006188- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006189 fails unicode conversion on 2nd parameter. (windows only)
6190
Georg Brandl222e2082010-08-01 22:27:39 +00006191- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006192 in a redirect.
6193

Brett Cannon721b1452008-08-16 22:00:27 +00006195 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006196
Facundo Batistaeb90b782008-08-16 14:44:07 +00006197- Issue #2776: fixed small issue when handling an URL with double slash
6198 after a 302 response in the case of not going through a proxy.
6199
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006200- Issue #2676: in the email package, content-type parsing was hanging on
6201 pathological input because of quadratic or exponential behaviour of a
6202 regular expression.
6203
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006204- Issue #3476: binary buffered reading through the new "io" library is now
6205 thread-safe.
6206
Brett Cannonbf3157b2008-08-14 05:00:03 +00006207- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6208 since mimetools itself is deprecated. Because modules are cached, all
6209 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6210
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006211- Issue #3134: shutil referenced undefined WindowsError symbol.
6212
Robert Schuppenies14646332008-08-10 11:01:53 +00006213- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6214 menu entries were not deleted.
6215
Brett Cannon83e81842008-08-09 23:30:55 +00006216- Copied the implementation of reduce() to _functools.reduce() to have a
6217 version that did not raise a DeprecationWarning under -3.

Antoine Pitroude781a42008-08-09 12:43:23 +00006245 asking for a specific length. This problem only affected files opened

6289
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006290- Issue #643841: The language reference now provides more detailed
6291 coverage of the lookup process for special methods. The disclaimers
6292 regarding lack of coverage of new-style classes have also been

6298
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006299*Release date: 17-Jul-2008*

6302-----------------
6303
Georg Brandl3e483f62008-07-16 22:57:41 +00006304- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6305 its methods now allow for items objects that can be converted to
6306 an integer using operator.index().
6307
Mark Dickinson64b7e502008-07-16 09:40:03 +00006308- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6309 produced a ValueError instead of giving the correct float.
6310
Eric Smitha5fa5a22008-07-16 00:11:49 +00006311- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6312 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6313
Mark Dickinson7103aa42008-07-15 19:08:33 +00006314- Issue #3008: the float type has a new instance method 'float.hex'
6315 and a new class method 'float.fromhex' to convert floating-point
6316 numbers to and from hexadecimal strings, respectively.
6317
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006318- Issue #2235: __hash__ is once again inherited by default. To allow
6319 collections.Hashable to remain meaningful in the presence of the
6320 default hash implementation (object.__hash__), it is now possible
6321 to explicit block inheritance of hash by setting __hash__=None at
6322 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6323 level.
6324
Nick Coghlanb028f502008-07-13 14:52:36 +00006325- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6326 the parent module cannot be found while performing an absolute import.
6327 This means that an incorrectly defined __package__ attribute will
6328 now only prevent relative imports in that module rather than causing
6329 all imports from that module to fail.
6330
Nick Coghlan14ff9942008-07-08 14:21:42 +00006331- Issue #2517: Allow unicode messages in Exceptions again by correctly

6341 another thread's dictionary.
6342
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006343- Issue #3004: Minor change to slice.indices(): the start and stop
6344 arguments are now treated identically, making the behaviour easier
6345 to describe and understand. For example, slice(None, -10,
6346 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6347 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6348 10, -1).
6349
Georg Brandl278fc502008-07-19 12:46:12 +00006350- Issue #3219: Calling a function with repeated keyword arguments,
6351 f(a=2, a=23), would not cause a syntax error. This was a regression
6352 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006353
Georg Brandl278fc502008-07-19 12:46:12 +00006354- Issue #2862: Make int and float freelist management consistent with
6355 other freelists. Changes their CompactFreeList apis into

6362 api functions without holding the GIL, which could lead to a fatal
6363 error when they failed.
6364
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006365- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006390- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6391 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006392 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006393 content-length. The problem had been corrected in the 2.4 branch, but never
6394 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006409- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

6797
Brett Cannonb61d8012008-05-11 23:39:04 +00006798- ``Lib/lib-old`` is now added to sys.path.
6799
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006800- On MacOS X it is now possible to install the framework in 64-bit
6801 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006802 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006803
6804 This is controlled by the configure argument ``--with-universal-archs``:
6805
6806 - ``--with-universal-archs=all``: install 4-way universal
6807
6808 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6809
6810 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6811
6812 This option should be used in combination with ``--enable-universalsdk=``.
6813
6814 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00006823
6824- The PyString functions have been renamed to PyBytes. A batch of
6825 defines were added so that the linker still sees the original
6826 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006864- Issue #1631171: Re-implement the 'warnings' module in C (the
6865 original Python code has been kept as backup). This will allow for
6866 using the 'warning's machinery in such places as the parser where
6867 use of pure Python code is not possible. Both the ``showarning()``
6868 and ``formatwarning()`` gain an optional 'line' argument which is
6869 not called by default for backwards-compatibility reasons. Setting
6870 ``warnings.showwarning()`` to an implementation that lacks support
6871 for the ``line`` argument will raise a DeprecationWarning.

6895
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00006896- The getpass module has been improved on Unix. It now uses /dev/tty
6897 by default and uses stderr instead of stdout. A GetPassWarning is
6898 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00006899

6910 implementation detail of the public ``types`` module, has been
6911 removed and replaced by pure python code.
Amaury Forgeot d'Arc02f33b42008-04-08 23:10:07 +00006912
Georg Brandl3ee81df2008-05-17 18:14:43 +00006913- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00006914 extension modules between 32 and 64 bit platforms. See the distutls
6915 build documentation for more information.

6918 threads at once without fear of crashing the Python interpreter. If
6919 file.close() is called while an object is in use by another thread
6920 an IOError exception will be raised and the file will not be closed.
6921
Thomas Hellerf7906482008-04-04 19:43:25 +00006922- The bundled libffi copy is now in sync with the recently released

6927 so the controlled environment will more closely mirror the typical
6928 script environment. This supports setup.py scripts that refer to
6929 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006934- Issue #2550: The approach used by client/server code for obtaining
6935 ports to listen on in network-oriented tests has been refined in an
6936 effort to facilitate running multiple instances of the entire
6937 regression test suite in parallel without issue.
6938 test_support.bind_port() has been fixed such that it will always
6939 return a unique port -- which wasn't always the case with the
6940 previous implementation, especially if socket options had been set
6941 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6942 new implementation of bind_port() will actually raise an exception
6943 if it is passed an AF_INET/SOCK_STREAM socket with either the
6944 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6945 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6946 the socket it's been passed. This currently only applies to
6947 Windows. This option prevents any other sockets from binding to the
6948 host/port we've bound to, thus removing the possibility of the
6949 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6950 when a second SOCK_STREAM socket binds and accepts to a host/port
6951 that's already been bound by another socket. The optional preferred
6952 port parameter to bind_port() has been removed. Under no
6953 circumstances should tests be hard coding ports!
6954
6955 test_support.find_unused_port() has also been introduced, which will
6956 pass a temporary socket object to bind_port() in order to obtain an
6957 unused port. The temporary socket object is then closed and
6958 deleted, and the port is returned. This method should only be used
6959 for obtaining an unused port in order to pass to an external program
6960 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6961 a parameter to a server-oriented class that doesn't give you direct
6962 access to the underlying socket used.
6963
6964 Finally, test_support.HOST has been introduced, which should be used
6965 for the host argument of any relevant socket calls (i.e. bind and
6966 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006967
6968 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006969 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006970 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6971 test_asynchat and test_socket_ssl.
6972
Georg Brandl3ee81df2008-05-17 18:14:43 +00006973 It is now possible for multiple instances of the regression test
6974 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00007253- Added the future_builtins module, which contains hex() and oct().
7254 These are the PEP 3127 version of these functions, designed to be
7255 compatible with the hex() and oct() builtins from Python 3.0. They
7256 differ slightly in their output formats from the existing, unchanged
7257 Python 2.6 builtins. The expected usage of the future_builtins
7258 module is:
7259 from future_builtins import hex, oct
7260
Eric Smith7ef40bf2008-02-20 23:34:22 +00007261- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7262 exponents for exponents with absolute value < 100. Follows C99
7263 standard. This is a change on Windows, which would use 3 digits.
7264 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7265 so that any alterations it does to the resulting string will be
7266 available in stringlib/formatter.h (for float.__format__).
7267
Eric Smith5a3c1352008-02-19 13:21:56 +00007268- Implemented PEP 3101, Advanced String Formatting. This adds a new
7269 builtin format(); a format() method for str and unicode; a
7270 __format__() method to object, str, unicode, int, long, float, and
7271 datetime; the class string.Formatter; and the C API
7272 PyObject_Format().
7273
Georg Brandl3ee81df2008-05-17 18:14:43 +00007274- Fixed several potential crashes, all caused by specially crafted
7275 __del__ methods exploiting objects in temporarily inconsistent
7276 state.

7286 in order to allow pymalloc to free more arenas. Python may give back
7287 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007288
Georg Brandl3ee81df2008-05-17 18:14:43 +00007289- Issue #2045: Fix an infinite recursion triggered when printing a
7290 subclass of collections.defaultdict, if its default_factory is set
7291 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007292
Christian Heimesf75dbef2008-02-08 00:11:31 +00007293- Fixed a minor memory leak in dictobject.c. The content of the free
7294 list was not freed on interpreter shutdown.
7295
Georg Brandl21e99f42010-03-07 15:23:59 +00007296- Limit free list of method and built-in function objects to 256

7300 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007301 to compact the internal free lists of pre-allocted ints and floats.
7302
Georg Brandl3ee81df2008-05-17 18:14:43 +00007303- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7304 calls. Python expected the return type int but the fork familie

Georg Brandl3ee81df2008-05-17 18:14:43 +00007316- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7317 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007318
Georg Brandl3ee81df2008-05-17 18:14:43 +00007319- Patch #1473257: generator objects gain a gi_code attribute. This is
7320 the same object as the func_code attribute of the function that
7321 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007322
Georg Brandl3ee81df2008-05-17 18:14:43 +00007323- Issue #1920: "while 0" statements were completely removed by the
7324 compiler, even in the presence of an "else" clause, which is
7325 supposed to be run when the condition is false. Now the compiler
7326 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007327
Guido van Rossumeead05f2008-01-24 18:21:02 +00007328- A few crashers fixed: weakref_in_del.py (issue #1377858);
7329 loosing_dict_ref.py (issue #1303614, test67.py);
7330 borrowed_ref_[34].py (not in tracker).
7331
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007332- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007333 suppressed while an extension is loaded by calling SetErrorMode in
7334 dynload_win.c. The error is still reported properly.
7335
Georg Brandl3ee81df2008-05-17 18:14:43 +00007336- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007337 several extension methods and modules do not work without unicode
7338 support.
7339
Georg Brandl26543b12008-01-21 18:36:51 +00007340- Issue #1882: when compiling code from a string, encoding cookies in the
7341 second line of code were not always recognized correctly.
7342
Georg Brandl14404b62008-01-19 19:27:05 +00007343- Issue #1679: "0x" was taken as a valid integer literal.
7344
Georg Brandl6caad7d2008-01-26 14:19:22 +00007345- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007346 added.
7347
Christian Heimesc94e2b52008-01-14 04:13:37 +00007348- sys.float_info / PyFloat_GetInfo: The floating point information
7349 object was converted from a dict to a specialized structseq object.
7350
Georg Brandl3ee81df2008-05-17 18:14:43 +00007351- Patch #1816: Added sys.flags structseq. It exposes the status of
7352 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007353
Georg Brandl3ee81df2008-05-17 18:14:43 +00007354- Objects/structseq.c: Implemented new structseq representation. The
7355 patch makes structseqs (e.g. the return value of os.stat) more
7356 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007357
Georg Brandl3ee81df2008-05-17 18:14:43 +00007358- Patch #1700288: added a type attribute cache that caches method
7359 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007360
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007361- Bug #1776: __import__() no longer accepts filenames on any platform.
7362 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007363
Georg Brandlaed6c662008-01-07 17:25:53 +00007364- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7365
Georg Brandl3ee81df2008-05-17 18:14:43 +00007366- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7367 envvar and sys.dont_write_bytecode attribute. All these can be set
7368 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007369
Georg Brandl3ee81df2008-05-17 18:14:43 +00007370- Improve some exception messages when Windows fails to load an
7371 extension module. Now we get for example '%1 is not a valid Win32
7372 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00007379- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007380 and INF. float("nan"), float("inf") and float("-inf") now work on
7381 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007382
Georg Brandl3ee81df2008-05-17 18:14:43 +00007383- Compiler now generates simpler and faster code for dictionary
7384 literals. The oparg for BUILD_MAP now indicates an estimated
7385 dictionary size. There is a new opcode, STORE_MAP, for adding
7386 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007415- Patch #1739468: Directories and zipfiles containing a __main__.py
7416 file can now be directly executed by passing their name to the
7417 interpreter. The directory/zipfile is automatically inserted as the
7418 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007419
Georg Brandl3ee81df2008-05-17 18:14:43 +00007420- Issue #1265: Fix a problem with sys.settrace, if the tracing
7421 function uses a generator expression when at the same time the
7422 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007423
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007424- sets and frozensets now have an isdisjoint() method.
7425
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007426- optimize the performance of builtin.sum().
7427
Neal Norwitz44f326e2007-10-05 05:29:17 +00007428- Fix warnings found by the new version of the Coverity checker.
7429
Georg Brandl21e99f42010-03-07 15:23:59 +00007430- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007431 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7432 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007433
Georg Brandl3ee81df2008-05-17 18:14:43 +00007434- Issue #1686386: Tuple's tp_repr did not take into account the
7435 possibility of having a self-referential tuple, which is possible
7436 from C code. Nor did object's tp_str consider that a type's tp_str
7437 could do something that could lead to an inifinite recursion.
7438 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7439 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007440
Georg Brandl3ee81df2008-05-17 18:14:43 +00007441- Issue #1164: It was possible to trigger deadlock when using the
7442 'print' statement to write to a file since the GIL was not released
7443 as needed. Now PyObject_Print() does the right thing along with
7444 various tp_print implementations of the built-in types and those in
7445 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007446
Georg Brandl3ee81df2008-05-17 18:14:43 +00007447- Issue #1147: Exceptions were directly allowing string exceptions in
7448 their throw() method even though string exceptions no longer
7449 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007450
Georg Brandl3ee81df2008-05-17 18:14:43 +00007451- Issue #1096: Prevent a segfault from getting the repr of a very
7452 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007453
Brett Cannon1e534b52007-09-07 04:18:30 +00007454- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007455 PyObject_Call() never calling back out to Python code to trigger
7456 recursion depth updates/checks. Required the creation of a static
7457 RuntimeError instance in case normalizing an exception put the
7458 recursion check value past its limit. Fixes crashers
7459 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007460

Neal Norwitz0ac60192007-05-27 04:08:54 +00007474- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007475 __*__ attributes. (Some already existed, e.g., __doc__ and
7476 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007477
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007478- Add -3 option to the interpreter to warn about features that are
7479 deprecated and will be changed/removed in Python 3.0.
7480
Georg Brandl2134e752007-05-21 20:34:16 +00007481- Patch #1686487: you can now pass any mapping after '**' in function
7482 calls.
7483
Collin Winter62903052007-05-18 23:11:24 +00007484- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007485 "except E as target:". This is to provide forwards compatibility
7486 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00007488- Deprecate BaseException.message as per PEP 352.
7489
Georg Brandl3ee81df2008-05-17 18:14:43 +00007490- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007491 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007492
Vinay Sajip8549ce32007-05-06 17:53:37 +00007493- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007494 setting a plain string, ie don't expand to single letter identifiers.
7495
Raymond Hettinger13936692007-04-11 18:40:58 +00007496- Request #1191699: Slices can now be pickled.
7497
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007498- Request #1193128: str.translate() now allows a None argument for
7499 translations that only remove characters without re-mapping the
7500 remaining characters.
7501
Georg Brandl5cb76c12007-03-21 09:00:39 +00007502- Patch #1682205: a TypeError while unpacking an iterable is no longer
7503 masked by a generic one with the message "unpack non-sequence".
7504
Neal Norwitzaa754b72007-03-21 06:39:48 +00007505- Remove unused file Python/fmod.c.
7506
Guido van Rossum143b5642007-03-23 04:58:42 +00007507- Bug #1683368: The object.__init__() and object.__new__() methods are
7508 now stricter in rejecting excess arguments. The only time when
7509 either allows excess arguments is when it is not overridden and the
7510 other one is. For backwards compatibility, when both are
7511 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007512 warning later). Also, type.__init__() insists on the same signature
7513 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007514
Georg Brandl3ee81df2008-05-17 18:14:43 +00007515- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7516 object to complex using its __complex__() method before falling back
7517 to the __float__() method. Therefore, the functions in the cmath
7518 module now can operate on objects that define a __complex__()
7519 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007521- Patch #1623563: allow __class__ assignment for classes with
7522 __slots__. The old and the new class are still required to have the
7523 same slot names.

7529 ``object.__reduce_ex__()`` is called with an object that is faking
7530 its type.

7536
Georg Brandl7b9c5552007-03-12 14:30:05 +00007537- Bug #1678647: write a newline after printing an exception in any
7538 case, even when converting the value to a string failed.
7539
Georg Brandl871f1bc2007-03-12 13:17:36 +00007540- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007541 its argument, if it exists. If not, it will work like before. This
7542 allows customizing the output of dir() in the presence of a
7543 __getattr__().

Georg Brandl4e933132006-09-06 20:05:58 +00007658- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007676 generator expressions (x for x, in ... ) works again. Fixing this
7677 problem required changing the .pyc magic number. This means that

Georg Brandl3ee81df2008-05-17 18:14:43 +00008067 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00008108 AttributeError instead of an IOError when the server's response
8109 didn't contain a valid HTTP status line.

8200 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00008593 time so that opening a database previously created with the DB_DUP
8594 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8595 opens. Specifically: dictionary assignment to a DB object will
8596 replace all values for a given key when the database allows
8597 duplicate values. DB users should use DB.put(k, v) when they want
8598 to store duplicates; not DB[k] = v.

8605 characters with ASCII value less than 32. Also, it correctly quotes
8606 dots only if they occur on a single line, as opposed to the previous
8607 behavior of quoting dots if they are the second character of any
8608 line.
