799 32-bit-only installer Pythons on systems with Xcode 4 (currently
800 OS X 10.8, 10.7, and optionally 10.6).
801 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
802 * Since Xcode 4 removes ppc support, extension module builds now
803 check for ppc compiler support and by default remove ppc and
804 ppc64 archs when they are not available.
805 * Extension module builds now revert to using system installed
806 headers and libs (/usr and /System/Library) if the SDK used
807 to build the interpreter is not installed or has moved.
808 * Try to avoid building extension modules with deprecated
809 and problematic Apple llvm-gcc compiler. If original compiler
810 is not available, use clang instead by default.

1156 distutils.sysconfig and another copy in distutils.ccompiler, with some
1157 parts of distutils calling one and others using the other.
1158 Complete the revert back to only having one in distutils.sysconfig as
1159 is the case in 3.x.

Ned Deily0d0ea482012-02-10 12:59:06 +01001161- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1162 Distutils-based packages with C extension modules may fail because
1163 Apple has removed gcc-4.2, the version used to build python.org
1164 64-bit/32-bit Pythons. If the user does not explicitly override
1165 the default C compiler by setting the CC environment variable,
1166 Distutils will now attempt to compile extension modules with clang
1167 if gcc-4.2 is required but not found. Also as a convenience, if
1168 the user does explicitly set CC, substitute its value as the default
1169 compiler in the Distutils LDSHARED configuration variable for OS X.
1170 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1171 SDK, neither of which are available in Xcode 4. This change does not
1172 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001445- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1446 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1447 interpreter process. This could cause failures in non-Distutils subprocesses
1448 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001449 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001450 deployment target only in the environment of each build subprocess. It is
1451 still possible to globally override the default by setting
1452 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1453 greater or equal to the default value, the value with which the interpreter
1454 was built.

1484 the ticker doesn't have to wind down to zero from the old starting point
1485 before the new interval takes effect. And if the user increases the
1486 interval, it makes sure the new limit takes effect right away rather have an
1487 early task switch before recognizing the new interval.

2439 This prevents user-created self-referencing ordered dictionaries from
2440 becoming permanently uncollectable GC garbage. The downside is that

2900-----------------
2901
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002902- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2903 start byte and the continuation byte(s) are now considered invalid, instead
2904 of the number of bytes specified by the start byte.
2905 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2906 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2907 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2908 Previous versions returned a single u'\ufffd'.
2909
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00002910- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00002911 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
2912 arises from the "Overriding __eq__ blocks inheritance ..." warning
2913 when turned into an exception: in this case the exception simply
2914 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00002915
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002916- Issue #8748: Fix two issues with comparisons between complex and integer
2917 objects. (1) The comparison could incorrectly return True in some cases
2918 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2919 (2) The comparison raised an OverflowError for large integers, leading
2920 to unpredictable exceptions when combining integers and complex objects
2921 in sets or dicts.
2922
Mark Dickinson81336372010-05-30 12:12:25 +00002923- Issue #5211: Implicit coercion for the complex type is now completely
2924 removed. (Coercion for arithmetic operations was already removed in 2.7
2925 alpha 4, but coercion for rich comparisons was accidentally left in.)
2926
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00002927- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
2928 and error handler, instead of writing to the C stderr file in utf-8
2929
Georg Brandlfee0f442010-05-22 21:26:21 +00002930- Issue #7902: When using explicit relative import syntax, don't try implicit

Georg Brandlfee0f442010-05-22 21:26:21 +00003303- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3304 with a non-empty format string. This is an effort to future-proof user
3305 code. If a derived class does not currently implement __format__ but later
3306 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003307 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003308 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003369 argument `-` which tells it to read files to compile from stdin. Each line is
3370 read on demand and the named file is compiled immediately. (Original patch by
3371 Piotr Ożarowski).

3381 Fractions instance now raise TypeError instead of returning True/False. This
3382 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3383 <=> complex, and complex <=> complex comparisons.

3746 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3747 returning NULL. The macro now returns a statically allocated empty string
3748 instead.

3758 strings,
3759 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
3760 numeric strings corresponding to subnormal values,
3761 (3) a memory leak for some values large enough to cause overflow, and
3762 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00003793- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00003794 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00003795 Also, raise ValueError rather than TypeError when an unknown TIPC address
3796 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003800- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003801 file position when calling `truncate()`. It would previously change the file
3802 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003803 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3804

3806 class used to represent files stored inside an archive. The new
3807 implementation is significantly faster and can be wrapped in a
3808 ``io.BufferedReader`` object for more speedups. It also solves an issue
3809 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
3810 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00003820- Issue #7748: Since unicode values are supported for some metadata options in
3821 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3822 encoded string for them. This ensures that the upload and register commands
3823 send the correct values to PyPI without any error.

3899
Georg Brandlba83f822010-03-14 09:50:54 +00003900- The ``__complex__()`` method is now looked up on the class of instances to
3901 make it consistent with other special methods.

3905
Mark Dickinson1b34d252010-01-01 17:27:30 +00003906- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003907 DeprecationWarning when passed a float argument where an integer was expected.
3908 These functions and methods now raise TypeError instead. The majority of the
3909 effects of this change are in the extension modules, but some core functions
3910 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3911 and many unicode/str methods.

3925 of integers: the result of a/b is now correctly rounded for ints a and b (at
3926 least on IEEE 754 platforms), and in particular does not depend on the
3927 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00003936 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00004094- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4095 decimal string that's guaranteed to round back to x under correct rounding
4096 (with round-half-to-even rounding mode). Previously it gave a string based on
4097 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4098 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4099 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00004101- Issue #7117: On almost all platforms: float-to-string and string-to-float
4102 conversions within Python are now correctly rounded. Places these conversions
4103 occur include: str for floats and complex numbers; the float and complex
4104 constructors; old-style and new-style numeric formatting; serialization and
4105 deserialization of floats and complex numbers using marshal, pickle and json;
4106 parsing of float and imaginary literals in Python code; Decimal-to-float
4107 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004108
Georg Brandlba83f822010-03-14 09:50:54 +00004109 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4110 providing correctly-rounded strtod and dtoa C functions. This code is
4111 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4112 the C compiler. There may be a small number of platforms on which correct
4113 operation of this code cannot be guaranteed, so the code is not used: notably,
4114 this applies to platforms where the C double format is not IEEE 754 binary64,
4115 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4116 and Python's configure script is unable to determine how to change the FPU
4117 precision. On these platforms conversions use the platform strtod and dtoa,
4118 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004120- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4121 uses the correctly-rounded string <-> float conversions described above (when
4122 available), and so produces correctly rounded results that will display nicely
4123 under the float repr. There are two related small changes: (1) round now
4124 accepts any class with an ``__index__()`` method for its second argument (but
4125 no longer accepts floats for the second argument), and (2) an excessively
4126 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4127 raises an exception.

5710 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
5711 neither __int__ nor __long__, TypeError used to be raised (with a

Georg Brandlba83f822010-03-14 09:50:54 +00005766 leak-chasing test runs give sensible results. The previous method of reaping
5767 threads could return successfully while some Thread objects were still
5768 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00005769
Georg Brandlba83f822010-03-14 09:50:54 +00005770- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer

Georg Brandlba83f822010-03-14 09:50:54 +00005787 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005910- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

5912 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5913 ``printf`` function, whereas PyString_FromFormat has an independent
5914 implementation and uses "%zd" on all platforms for size_t values.

5923 method is allowed to return either an int or a long, but the behaviour of
5924 float objects should not change to respect backward compatibility.
5925
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005926- Issue #3751: str.rpartition would perform a left-partition when called with
5927 a unicode argument.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005931- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00005932 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005933 was correctly parsed but parsing of subsequent arguments failed.
5934
Vinay Sajip35e3b032008-09-01 14:33:59 +00005935- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005936 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5937 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5938 when given a tuple of classes as second argument, were looking up
5939 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5940 type object.
5941
Neal Norwitz18aa3882008-08-24 05:04:52 +00005942- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006011 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6012 for catch_warnings() also led to an improvement in the raising of a
6013 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006079What's New in Python 2.6 beta 3?
6080================================
6081
Barry Warsaw07a4a382008-08-21 01:15:08 +00006082*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006083
6084Core and Builtins
6085-----------------
6086
Guido van Rossumf8402962008-08-20 15:01:50 +00006087- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6088 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6089 extensions do not automatically benefit from the class attribute
6090 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6091 to their tp_flags field if they care. This is a backwards
6092 compatibility feature; in 3.0, all types will use the cache by
6093 default.
6094
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006095- Keyword arguments can now follow starred arguments. (``f(a, *args,
6096 keyword=23)`` is now valid syntax.)
6097
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006098- ctypes function pointers that are COM methods have a boolean True
6099 value again.
6100
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006101- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6102 by denying s# to parse objects that have a releasebuffer procedure,
6103 and introducing s*.
6104
Georg Brandl1e13ea92008-08-11 09:07:59 +00006105- Issue #3537: Fix an assertion failure when an empty but presized dict
6106 object was stored in the freelist.
6107
Mark Dickinsonb6467572008-08-04 21:30:09 +00006108- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6109 ValueError consistently across platforms.
6110
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006111- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6112 (64bit Unix, for example), unichr() would truncate its argument and return
6113 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6114
Neal Norwitze7d8be82008-07-31 17:17:14 +00006115- Apply security patches from Apple.
6116
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006117- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6118 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6119
Antoine Pitrou92f82162008-07-25 22:22:08 +00006120- Issue #1819: function calls with several named parameters are now on
6121 average 35% faster (as measured by pybench).
6122
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006123- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6124 the python debugger steps into a class statement: the free variables (local
6125 variables defined in an outer scope) would be deleted from the outer scope.
6126
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006127- Issue #2620: Overflow checking when allocating or reallocating memory
6128 was not always being done properly in some python types and extension
6129 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6130 all been updated to perform better checks and places in the code that
6131 would previously leak memory on the error path when such an allocation
6132 failed have been fixed.

6135-------
6136
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006137- Issue #3612: Added some missing basic types in ctypes.wintypes.
6138
Benjamin Petersone977ad42008-08-20 01:42:01 +00006139- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6140 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6141
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006142- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6143 version reported by these tools does not necessarily follow the python
6144 version numbering scheme, so the module is less strict when parsing it.
6145
Nick Coghlanf70385a2008-08-18 12:42:46 +00006146- Issue #2235: Added Py3k warnings for types which will become unhashable
6147 under the stricter __hash__ inheritance rules in 3.0. Several types
6148 which did not meet the rules for hash invariants and were already
6149 unhashable in 3.0 have now been explicitly flagged as unhashable in
6150 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6151 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6152
Brett Cannon88f801d2008-08-18 00:46:22 +00006153- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6154 imported into the module but exposed as part of the module's API.
6155
Brett Cannon7b96f072008-08-18 00:41:11 +00006156- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6157
Brett Cannon46225e72008-08-18 00:36:52 +00006158- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

6161
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006162- Issue #3575: Incremental decoder's decode function now takes bytearray
6163 by using 's*' instead of 't#'.
6164
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006165- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006166 fails unicode conversion on 2nd parameter. (windows only)
6167
Georg Brandl222e2082010-08-01 22:27:39 +00006168- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006169 in a redirect.
6170
Brett Cannonabe423e2008-08-16 21:47:07 +00006171- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006172 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006173
Facundo Batistaeb90b782008-08-16 14:44:07 +00006174- Issue #2776: fixed small issue when handling an URL with double slash
6175 after a 302 response in the case of not going through a proxy.
6176
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006177- Issue #2676: in the email package, content-type parsing was hanging on
6178 pathological input because of quadratic or exponential behaviour of a
6179 regular expression.
6180
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006181- Issue #3476: binary buffered reading through the new "io" library is now
6182 thread-safe.
6183
Brett Cannonbf3157b2008-08-14 05:00:03 +00006184- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6185 since mimetools itself is deprecated. Because modules are cached, all
6186 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6187
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006188- Issue #3134: shutil referenced undefined WindowsError symbol.
6189
Robert Schuppenies14646332008-08-10 11:01:53 +00006190- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6191 menu entries were not deleted.
6192
Brett Cannon83e81842008-08-09 23:30:55 +00006193- Copied the implementation of reduce() to _functools.reduce() to have a
6194 version that did not raise a DeprecationWarning under -3.
6195
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006196- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6197 a MemoryError rather than silently stop the iteration.
6198
Guido van Rossum59ce9012008-08-09 14:55:34 +00006199- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6200 to _sre.compile() will now be rejected. This should not affect anybody
6201 since the re.compile() function never generates invalid re-bytecode.
6202
Skip Montanaroa032bf42008-08-08 22:52:51 +00006203- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6204 upon first access it can be automatically initialized from the csv file if
6205 it wasn't initialized during instantiation.

Antoine Pitroude781a42008-08-09 12:43:23 +00006222 asking for a specific length. This problem only affected files opened

6279-----------------
6280
Georg Brandl3e483f62008-07-16 22:57:41 +00006281- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6282 its methods now allow for items objects that can be converted to
6283 an integer using operator.index().
6284
Mark Dickinson64b7e502008-07-16 09:40:03 +00006285- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6286 produced a ValueError instead of giving the correct float.
6287
Eric Smitha5fa5a22008-07-16 00:11:49 +00006288- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6289 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6290
Mark Dickinson7103aa42008-07-15 19:08:33 +00006291- Issue #3008: the float type has a new instance method 'float.hex'
6292 and a new class method 'float.fromhex' to convert floating-point
6293 numbers to and from hexadecimal strings, respectively.
6294
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006295- Issue #2235: __hash__ is once again inherited by default. To allow
6296 collections.Hashable to remain meaningful in the presence of the
6297 default hash implementation (object.__hash__), it is now possible
6298 to explicit block inheritance of hash by setting __hash__=None at
6299 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6300 level.
6301
Nick Coghlanb028f502008-07-13 14:52:36 +00006302- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6303 the parent module cannot be found while performing an absolute import.
6304 This means that an incorrectly defined __package__ attribute will
6305 now only prevent relative imports in that module rather than causing
6306 all imports from that module to fail.
6307
Nick Coghlan14ff9942008-07-08 14:21:42 +00006308- Issue #2517: Allow unicode messages in Exceptions again by correctly

6318 another thread's dictionary.
6319
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006320- Issue #3004: Minor change to slice.indices(): the start and stop
6321 arguments are now treated identically, making the behaviour easier
6322 to describe and understand. For example, slice(None, -10,
6323 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6324 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6325 10, -1).
6326
Georg Brandl278fc502008-07-19 12:46:12 +00006327- Issue #3219: Calling a function with repeated keyword arguments,
6328 f(a=2, a=23), would not cause a syntax error. This was a regression
6329 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00006331- Issue #2862: Make int and float freelist management consistent with
6332 other freelists. Changes their CompactFreeList apis into

6340 error when they failed.
6341
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006342- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006367- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6368 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006369 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006370 content-length. The problem had been corrected in the 2.4 branch, but never
6371 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006386- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

6774
Brett Cannonb61d8012008-05-11 23:39:04 +00006775- ``Lib/lib-old`` is now added to sys.path.
6776
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006777- On MacOS X it is now possible to install the framework in 64-bit
6778 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006779 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006780
6781 This is controlled by the configure argument ``--with-universal-archs``:
6782
6783 - ``--with-universal-archs=all``: install 4-way universal
6784
6785 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6786
6787 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6788
6789 This option should be used in combination with ``--enable-universalsdk=``.
6790
6791 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

6799- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00006800
6801- The PyString functions have been renamed to PyBytes. A batch of
6802 defines were added so that the linker still sees the original
6803 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006841- Issue #1631171: Re-implement the 'warnings' module in C (the
6842 original Python code has been kept as backup). This will allow for
6843 using the 'warning's machinery in such places as the parser where
6844 use of pure Python code is not possible. Both the ``showarning()``
6845 and ``formatwarning()`` gain an optional 'line' argument which is
6846 not called by default for backwards-compatibility reasons. Setting
6847 ``warnings.showwarning()`` to an implementation that lacks support
6848 for the ``line`` argument will raise a DeprecationWarning.

6872
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00006873- The getpass module has been improved on Unix. It now uses /dev/tty
6874 by default and uses stderr instead of stdout. A GetPassWarning is
6875 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006890- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00006891 extension modules between 32 and 64 bit platforms. See the distutls

6904 so the controlled environment will more closely mirror the typical
6905 script environment. This supports setup.py scripts that refer to
6906 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006911- Issue #2550: The approach used by client/server code for obtaining
6912 ports to listen on in network-oriented tests has been refined in an
6913 effort to facilitate running multiple instances of the entire
6914 regression test suite in parallel without issue.
6915 test_support.bind_port() has been fixed such that it will always
6916 return a unique port -- which wasn't always the case with the
6917 previous implementation, especially if socket options had been set
6918 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6919 new implementation of bind_port() will actually raise an exception
6920 if it is passed an AF_INET/SOCK_STREAM socket with either the
6921 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6922 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6923 the socket it's been passed. This currently only applies to
6924 Windows. This option prevents any other sockets from binding to the
6925 host/port we've bound to, thus removing the possibility of the
6926 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6927 when a second SOCK_STREAM socket binds and accepts to a host/port
6928 that's already been bound by another socket. The optional preferred
6929 port parameter to bind_port() has been removed. Under no
6930 circumstances should tests be hard coding ports!
6931
6932 test_support.find_unused_port() has also been introduced, which will
6933 pass a temporary socket object to bind_port() in order to obtain an
6934 unused port. The temporary socket object is then closed and
6935 deleted, and the port is returned. This method should only be used
6936 for obtaining an unused port in order to pass to an external program
6937 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6938 a parameter to a server-oriented class that doesn't give you direct
6939 access to the underlying socket used.
6940
6941 Finally, test_support.HOST has been introduced, which should be used
6942 for the host argument of any relevant socket calls (i.e. bind and
6943 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006944
6945 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006946 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006947 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6948 test_asynchat and test_socket_ssl.
6949
Georg Brandl3ee81df2008-05-17 18:14:43 +00006950 It is now possible for multiple instances of the regression test
6951 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00007230- Added the future_builtins module, which contains hex() and oct().
7231 These are the PEP 3127 version of these functions, designed to be
7232 compatible with the hex() and oct() builtins from Python 3.0. They
7233 differ slightly in their output formats from the existing, unchanged
7234 Python 2.6 builtins. The expected usage of the future_builtins
7235 module is:
7236 from future_builtins import hex, oct
7237
Eric Smith7ef40bf2008-02-20 23:34:22 +00007238- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7239 exponents for exponents with absolute value < 100. Follows C99
7240 standard. This is a change on Windows, which would use 3 digits.
7241 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7242 so that any alterations it does to the resulting string will be
7243 available in stringlib/formatter.h (for float.__format__).
7244
Eric Smith5a3c1352008-02-19 13:21:56 +00007245- Implemented PEP 3101, Advanced String Formatting. This adds a new
7246 builtin format(); a format() method for str and unicode; a
7247 __format__() method to object, str, unicode, int, long, float, and
7248 datetime; the class string.Formatter; and the C API
7249 PyObject_Format().
7250
Georg Brandl3ee81df2008-05-17 18:14:43 +00007251- Fixed several potential crashes, all caused by specially crafted
7252 __del__ methods exploiting objects in temporarily inconsistent
7253 state.

7264 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007265
Georg Brandl3ee81df2008-05-17 18:14:43 +00007266- Issue #2045: Fix an infinite recursion triggered when printing a
7267 subclass of collections.defaultdict, if its default_factory is set
7268 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007269
Christian Heimesf75dbef2008-02-08 00:11:31 +00007270- Fixed a minor memory leak in dictobject.c. The content of the free
7271 list was not freed on interpreter shutdown.
7272
Georg Brandl21e99f42010-03-07 15:23:59 +00007273- Limit free list of method and built-in function objects to 256

7277 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007278 to compact the internal free lists of pre-allocted ints and floats.
7279
Georg Brandl3ee81df2008-05-17 18:14:43 +00007280- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7281 calls. Python expected the return type int but the fork familie
7282 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007290- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
7291 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00007292
Georg Brandl3ee81df2008-05-17 18:14:43 +00007293- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7294 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007295
Georg Brandl3ee81df2008-05-17 18:14:43 +00007296- Patch #1473257: generator objects gain a gi_code attribute. This is
7297 the same object as the func_code attribute of the function that
7298 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007299
Georg Brandl3ee81df2008-05-17 18:14:43 +00007300- Issue #1920: "while 0" statements were completely removed by the
7301 compiler, even in the presence of an "else" clause, which is
7302 supposed to be run when the condition is false. Now the compiler
7303 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007304
Guido van Rossumeead05f2008-01-24 18:21:02 +00007305- A few crashers fixed: weakref_in_del.py (issue #1377858);
7306 loosing_dict_ref.py (issue #1303614, test67.py);
7307 borrowed_ref_[34].py (not in tracker).
7308
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007309- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007310 suppressed while an extension is loaded by calling SetErrorMode in
7311 dynload_win.c. The error is still reported properly.
7312
Georg Brandl3ee81df2008-05-17 18:14:43 +00007313- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007314 several extension methods and modules do not work without unicode
7315 support.
7316
Georg Brandl26543b12008-01-21 18:36:51 +00007317- Issue #1882: when compiling code from a string, encoding cookies in the
7318 second line of code were not always recognized correctly.
7319
Georg Brandl14404b62008-01-19 19:27:05 +00007320- Issue #1679: "0x" was taken as a valid integer literal.
7321
Georg Brandl6caad7d2008-01-26 14:19:22 +00007322- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007323 added.
7324
Christian Heimesc94e2b52008-01-14 04:13:37 +00007325- sys.float_info / PyFloat_GetInfo: The floating point information
7326 object was converted from a dict to a specialized structseq object.
7327
Georg Brandl3ee81df2008-05-17 18:14:43 +00007328- Patch #1816: Added sys.flags structseq. It exposes the status of
7329 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007330
Georg Brandl3ee81df2008-05-17 18:14:43 +00007331- Objects/structseq.c: Implemented new structseq representation. The
7332 patch makes structseqs (e.g. the return value of os.stat) more
7333 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007334
Georg Brandl3ee81df2008-05-17 18:14:43 +00007335- Patch #1700288: added a type attribute cache that caches method
7336 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007337
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007338- Bug #1776: __import__() no longer accepts filenames on any platform.
7339 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007340
Georg Brandlaed6c662008-01-07 17:25:53 +00007341- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7342
Georg Brandl3ee81df2008-05-17 18:14:43 +00007343- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7344 envvar and sys.dont_write_bytecode attribute. All these can be set
7345 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007346
Georg Brandl3ee81df2008-05-17 18:14:43 +00007347- Improve some exception messages when Windows fails to load an
7348 extension module. Now we get for example '%1 is not a valid Win32
7349 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007350
Georg Brandl3ee81df2008-05-17 18:14:43 +00007351- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007353- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
7354 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007355
Christian Heimes0a8143f2007-12-18 23:22:54 +00007356- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007357 and INF. float("nan"), float("inf") and float("-inf") now work on
7358 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007359
Georg Brandl3ee81df2008-05-17 18:14:43 +00007360- Compiler now generates simpler and faster code for dictionary
7361 literals. The oparg for BUILD_MAP now indicates an estimated
7362 dictionary size. There is a new opcode, STORE_MAP, for adding
7363 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00007364
Georg Brandl3ee81df2008-05-17 18:14:43 +00007365- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007370- Issue #1538: Avoid copying string in split/rsplit if the split char
7371 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00007372
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00007373- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00007374 SystemError.
7375
Nick Coghlanef01d822007-12-03 12:55:17 +00007376- PEP 366: Allow explicit relative imports when executing modules
7377 inside packages with the -m switch via a new module level
7378 __package__ attribute.
7379

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00007387 attribute of an empty cell object.
7388
Georg Brandl3ee81df2008-05-17 18:14:43 +00007389- Issue #1460: The utf-7 incremental decoder did not accept truncated
7390 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00007391
Georg Brandl3ee81df2008-05-17 18:14:43 +00007392- Patch #1739468: Directories and zipfiles containing a __main__.py
7393 file can now be directly executed by passing their name to the
7394 interpreter. The directory/zipfile is automatically inserted as the
7395 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007396
Georg Brandl3ee81df2008-05-17 18:14:43 +00007397- Issue #1265: Fix a problem with sys.settrace, if the tracing
7398 function uses a generator expression when at the same time the
7399 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007400
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007401- sets and frozensets now have an isdisjoint() method.
7402
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007403- optimize the performance of builtin.sum().
7404
Neal Norwitz44f326e2007-10-05 05:29:17 +00007405- Fix warnings found by the new version of the Coverity checker.
7406
Georg Brandl21e99f42010-03-07 15:23:59 +00007407- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007408 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7409 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007410
Georg Brandl3ee81df2008-05-17 18:14:43 +00007411- Issue #1686386: Tuple's tp_repr did not take into account the
7412 possibility of having a self-referential tuple, which is possible
7413 from C code. Nor did object's tp_str consider that a type's tp_str
7414 could do something that could lead to an inifinite recursion.
7415 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7416 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007417
Georg Brandl3ee81df2008-05-17 18:14:43 +00007418- Issue #1164: It was possible to trigger deadlock when using the
7419 'print' statement to write to a file since the GIL was not released
7420 as needed. Now PyObject_Print() does the right thing along with
7421 various tp_print implementations of the built-in types and those in
7422 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007423
Georg Brandl3ee81df2008-05-17 18:14:43 +00007424- Issue #1147: Exceptions were directly allowing string exceptions in
7425 their throw() method even though string exceptions no longer
7426 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007427
Georg Brandl3ee81df2008-05-17 18:14:43 +00007428- Issue #1096: Prevent a segfault from getting the repr of a very
7429 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007430
Brett Cannon1e534b52007-09-07 04:18:30 +00007431- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007432 PyObject_Call() never calling back out to Python code to trigger
7433 recursion depth updates/checks. Required the creation of a static
7434 RuntimeError instance in case normalizing an exception put the
7435 recursion check value past its limit. Fixes crashers
7436 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007437
Georg Brandl3ee81df2008-05-17 18:14:43 +00007438- Patch #1031213: Decode source line in SyntaxErrors back to its

7442 with %G.
7443
Georg Brandl3ee81df2008-05-17 18:14:43 +00007444- Prevent expandtabs() on string and unicode objects from causing a
7445 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00007446

Neal Norwitz0ac60192007-05-27 04:08:54 +00007451- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007452 __*__ attributes. (Some already existed, e.g., __doc__ and
7453 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007454
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007455- Add -3 option to the interpreter to warn about features that are
7456 deprecated and will be changed/removed in Python 3.0.
7457
Georg Brandl2134e752007-05-21 20:34:16 +00007458- Patch #1686487: you can now pass any mapping after '**' in function
7459 calls.
7460
Collin Winter62903052007-05-18 23:11:24 +00007461- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007462 "except E as target:". This is to provide forwards compatibility
7463 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007464
Brett Cannon229cee22007-05-05 01:34:02 +00007465- Deprecate BaseException.message as per PEP 352.
7466
Georg Brandl3ee81df2008-05-17 18:14:43 +00007467- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007468 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007469
Vinay Sajip8549ce32007-05-06 17:53:37 +00007470- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007471 setting a plain string, ie don't expand to single letter identifiers.
7472
Raymond Hettinger13936692007-04-11 18:40:58 +00007473- Request #1191699: Slices can now be pickled.
7474
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007475- Request #1193128: str.translate() now allows a None argument for
7476 translations that only remove characters without re-mapping the
7477 remaining characters.
7478
Georg Brandl5cb76c12007-03-21 09:00:39 +00007479- Patch #1682205: a TypeError while unpacking an iterable is no longer
7480 masked by a generic one with the message "unpack non-sequence".
7481
Neal Norwitzaa754b72007-03-21 06:39:48 +00007482- Remove unused file Python/fmod.c.
7483
Guido van Rossum143b5642007-03-23 04:58:42 +00007484- Bug #1683368: The object.__init__() and object.__new__() methods are
7485 now stricter in rejecting excess arguments. The only time when
7486 either allows excess arguments is when it is not overridden and the
7487 other one is. For backwards compatibility, when both are
7488 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007489 warning later). Also, type.__init__() insists on the same signature
7490 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007491
Georg Brandl3ee81df2008-05-17 18:14:43 +00007492- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7493 object to complex using its __complex__() method before falling back
7494 to the __float__() method. Therefore, the functions in the cmath
7495 module now can operate on objects that define a __complex__()
7496 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007497
Georg Brandl3ee81df2008-05-17 18:14:43 +00007498- Patch #1623563: allow __class__ assignment for classes with
7499 __slots__. The old and the new class are still required to have the
7500 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00007501
Georg Brandl3ee81df2008-05-17 18:14:43 +00007502- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00007505- Patch #1462488: Python no longer segfaults when
7506 ``object.__reduce_ex__()`` is called with an object that is faking
7507 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00007508
Georg Brandl3ee81df2008-05-17 18:14:43 +00007509- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00007512- Patch #1444529: the builtin compile() now accepts keyword arguments.
7513
Georg Brandl7b9c5552007-03-12 14:30:05 +00007514- Bug #1678647: write a newline after printing an exception in any
7515 case, even when converting the value to a string failed.
7516
Georg Brandl871f1bc2007-03-12 13:17:36 +00007517- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007518 its argument, if it exists. If not, it will work like before. This
7519 allows customizing the output of dir() in the presence of a
7520 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00007522- Patch #922167: Python no longer segfaults when faced with infinitely
7523 self-recursive reload() calls (as reported by bug #742342).
7524
Georg Brandl3ee81df2008-05-17 18:14:43 +00007525- Patch #1675981: remove unreachable code from ``type.__new__()``
7526 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00007527
Georg Brandl3ee81df2008-05-17 18:14:43 +00007528- Patch #1491866: change the complex() constructor to allow

8042
Facundo Batistad918a652007-04-24 13:54:38 +00008043- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008044 the client's request was successfully received, understood, and
8045 accepted. Now in these cases no error is raised in urllib (issue
8046 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00008047

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00008054- Added a timeout parameter to the constructor of other protocols
8055 (telnetlib, ftplib, smtplib and poplib). This is second part of the
8056 work started with create_connection() and timeout in httplib, and
8057 closes patch #723312.
8058
Vinay Sajip8549ce32007-05-06 17:53:37 +00008059- Patch #1676823: Added create_connection() to socket.py, which may be
8060 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00008061 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00008062
Martin v. Löwis0af33882007-03-23 13:27:15 +00008063- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008070- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
8071 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00008072 directories.
8073

8083
Georg Brandlf66b6032007-03-14 08:27:52 +00008084- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00008085 AttributeError instead of an IOError when the server's response
8086 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00008087
Georg Brandl3ee81df2008-05-17 18:14:43 +00008088- Patch #957650: "%var%" environment variable references are now
8089 properly expanded in ntpath.expandvars(), also "~user" home
8090 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00008091
Georg Brandl3ee81df2008-05-17 18:14:43 +00008092- Patch #1429539: pdb now correctly initializes the __main__ module
8093 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00008094 correctly now.
8095
Georg Brandlbad6f192007-03-13 21:32:56 +00008096- The nonobvious commands.getstatus() function is now deprecated.

8102
Georg Brandl3ee81df2008-05-17 18:14:43 +00008103- Patch #1530482: add pydoc.render_doc() which returns the
8104 documentation for a thing instead of paging it to stdout, which
8105 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00008106
Georg Brandl3ee81df2008-05-17 18:14:43 +00008107- Patch #1533909: the timeit module now accepts callables in addition

8114 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00008116- Patch #1581073: add a flag to textwrap that prevents the dropping of

8118
Georg Brandl92a6bae2007-03-13 17:43:32 +00008119- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008120 are set for invalid interpolation sequences that would lead to
8121 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00008122

8135
Georg Brandl94fe3f52007-03-13 09:32:11 +00008136- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00008137 field names in its exception message if you try to write a record
8138 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00008156

8164 returned string up to the first NUL character.

8175
Georg Brandl3ee81df2008-05-17 18:14:43 +00008176- unittest now verifies more of its assumptions. In particular,
8177 TestCase and TestSuite subclasses (not instances) are no longer
8178 accepted in TestSuite.addTest(). This should cause no
8179 incompatibility since it never made sense with ordinary subclasses
8180 -- the failure just occurred later, with a more cumbersome
8181 exception.

8190 given a unicode argument and os.listdir() returns unicode filenames.
8191
Georg Brandl3ee81df2008-05-17 18:14:43 +00008192- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00008570 time so that opening a database previously created with the DB_DUP
8571 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8572 opens. Specifically: dictionary assignment to a DB object will
8573 replace all values for a given key when the database allows
8574 duplicate values. DB users should use DB.put(k, v) when they want
8575 to store duplicates; not DB[k] = v.

8582 characters with ASCII value less than 32. Also, it correctly quotes
8583 dots only if they occur on a single line, as opposed to the previous
8584 behavior of quoting dots if they are the second character of any
8585 line.
