13 is modified during the lifetime of the Python process after zipimport has
14 already cached the zip's table of contents we detect this and recover

1575 In particular, fix extension module build failures when trying to use
1576 32-bit-only installer Pythons on systems with Xcode 4 (currently
1577 OS X 10.8, 10.7, and optionally 10.6).
1578 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1579 * Since Xcode 4 removes ppc support, extension module builds now
1580 check for ppc compiler support and by default remove ppc and
1581 ppc64 archs when they are not available.
1582 * Extension module builds now revert to using system installed
1583 headers and libs (/usr and /System/Library) if the SDK used
1584 to build the interpreter is not installed or has moved.
1585 * Try to avoid building extension modules with deprecated
1586 and problematic Apple llvm-gcc compiler. If original compiler
1587 is not available, use clang instead by default.

Ned Deily0d0ea482012-02-10 12:59:06 +01002018- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2019 Distutils-based packages with C extension modules may fail because
2020 Apple has removed gcc-4.2, the version used to build python.org
2021 64-bit/32-bit Pythons. If the user does not explicitly override
2022 the default C compiler by setting the CC environment variable,
2023 Distutils will now attempt to compile extension modules with clang
2024 if gcc-4.2 is required but not found. Also as a convenience, if
2025 the user does explicitly set CC, substitute its value as the default
2026 compiler in the Distutils LDSHARED configuration variable for OS X.
2027 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2028 SDK, neither of which are available in Xcode 4. This change does not

Ned Deily87e82bb2011-06-28 19:52:59 -07002279- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2280 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2281 interpreter process. This could cause failures in non-Distutils subprocesses
2282 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002283 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002284 deployment target only in the environment of each build subprocess. It is
2285 still possible to globally override the default by setting
2286 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2287 greater or equal to the default value, the value with which the interpreter
2288 was built.

2317 updating the check interval, so if the user decreases the check interval,
2318 the ticker doesn't have to wind down to zero from the old starting point
2319 before the new interval takes effect. And if the user increases the
2320 interval, it makes sure the new limit takes effect right away rather have an
2321 early task switch before recognizing the new interval.

3291 by Andrew Bennetts.

3300
Raymond Hettinger20397532010-09-12 02:11:45 +00003301- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3302 This prevents user-created self-referencing ordered dictionaries from
3303 becoming permanently uncollectable GC garbage. The downside is that
3304 removing __del__ means that the internal doubly-linked list has to wait for
3305 GC collection rather than freeing memory immediately when the refcnt drops
3306 to zero.
3307
Raymond Hettingerffd2a422010-09-10 10:47:22 +00003308- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

3311
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003312- Issue #9792: In case of connection failure, socket.create_connection()
3313 would swallow the exception and raise a new one, making it impossible
3314 to fetch the original errno, or to filter timeout errors. Now the
3315 original error is re-raised.
3316
Antoine Pitrouf4f61712010-09-07 16:34:47 +00003317- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
3318 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
3319 be updated back after the system call. Original patch by Brian Brazil.

3326
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00003327- Issue #808164: Fixed socket.close to avoid references to globals, to
3328 avoid issues when socket.close is called from a __del__ method.
3329
Terry Reedyd2d2ae92010-11-11 23:22:19 +00003330- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which
3331 can be set to False to turn off the previously undocumented 'popularity'
3332 heuristic. Patch by Terry Reedy and Eli Bendersky
3333
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00003334- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
3335 falling into recursion.
3336
R. David Murray7c4bf552010-08-25 01:45:57 +00003337- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3338 character years even if the message contains RFC822 two character years.
3339
Daniel Stutzbach91287322010-08-24 21:09:30 +00003340- Issue #8750: Fixed MutableSet's methods to correctly handle

Raymond Hettinger917bba12010-08-22 08:01:58 +00003351- Issue #9214: Set operations on KeysView or ItemsView in the collections
3352 module now correctly return a set. (Patch by Eli Bendersky.)
3353
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00003354- Issue #9617: Signals received during a low-level write operation aren't
3355 ignored by the buffered IO layer anymore.
3356
Benjamin Peterson52c36052010-08-21 03:03:22 +00003357- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
3358 are not held onto after they are deleted elsewhere.
3359
Raymond Hettingera54b2da2010-08-17 19:03:06 +00003360- Issue #9626: the view methods for collections.OrderedDict() were returning
3361 the unordered versions inherited from dict. Those methods are now
3362 overridden to provide ordered views.
3363
Éric Araujo0389ae62010-08-14 03:07:46 +00003364- Issue #8688: MANIFEST files created by distutils now include a magic
3365 comment indicating they are generated. Manually maintained MANIFESTs
3366 without this marker will not be overwritten or removed.
3367
Antoine Pitroue1436d12010-08-12 15:25:51 +00003368- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
3369 and a BadZipfile error is raised if it doesn't match (as used to be the
3370 case in Python 2.5 and earlier).
3371
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003372- Issue #9550: a BufferedReader could issue an additional read when the
3373 original read request had been satisfied, which could block indefinitely
3374 when the underlying raw IO channel was e.g. a socket. Report and original
3375 patch by Jason V. Miller.
3376
Fred Drake0a1fa0e2010-08-10 13:09:54 +00003377- Issue #9551: Don't raise TypeError when setting the value to None for

3396 This is how it is supposed to work, wget and curl do the same. Previous
3397 behavior was wrong.

3405 the option character for the added 'h/help' option if prefix_chars
3406 does not contain a '-', instead of raising an error.
3407

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003778- Issue #8748: Fix two issues with comparisons between complex and integer
3779 objects. (1) The comparison could incorrectly return True in some cases
3780 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3781 (2) The comparison raised an OverflowError for large integers, leading
3782 to unpredictable exceptions when combining integers and complex objects

Georg Brandlfee0f442010-05-22 21:26:21 +00004165- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4166 with a non-empty format string. This is an effort to future-proof user
4167 code. If a derived class does not currently implement __format__ but later
4168 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004169 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004170 Python 3.3 and it will be an error in Python 3.4.

4221 InvalidOperation instead of returning False. (Comparisons involving a quiet
4222 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4223 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00004225- Issue #2531: Comparison operations between floats and Decimal instances now
4226 return a result based on the numeric values of the operands; previously they

4243 Fractions instance now raise TypeError instead of returning True/False. This
4244 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4245 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00004663 file position when calling `truncate()`. It would previously change the file
4664 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004665 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4666

4668 class used to represent files stored inside an archive. The new
4669 implementation is significantly faster and can be wrapped in a
4670 ``io.BufferedReader`` object for more speedups. It also solves an issue
4671 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

4684 encoded string for them. This ensures that the upload and register commands
4685 send the correct values to PyPI without any error.

4761
Georg Brandlba83f822010-03-14 09:50:54 +00004762- The ``__complex__()`` method is now looked up on the class of instances to
4763 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00004764
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004765- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,

4767
Mark Dickinson1b34d252010-01-01 17:27:30 +00004768- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004769 DeprecationWarning when passed a float argument where an integer was expected.
4770 These functions and methods now raise TypeError instead. The majority of the
4771 effects of this change are in the extension modules, but some core functions
4772 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4773 and many unicode/str methods.

4785
Georg Brandlba83f822010-03-14 09:50:54 +00004786- Issue #1811: Improve accuracy and cross-platform consistency for true division
4787 of integers: the result of a/b is now correctly rounded for ints a and b (at
4788 least on IEEE 754 platforms), and in particular does not depend on the
4789 internal representation of a long.

Ronald Oussoren92919a62009-12-24 13:30:58 +00004796 executables on OSX.
4797
Georg Brandlba83f822010-03-14 09:50:54 +00004798 These executables now work properly with the arch(1) command: ``arch -ppc
4799 python`` will start a universal binary version of python in PPC mode (unlike
4800 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00004822 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

Georg Brandlba83f822010-03-14 09:50:54 +00004962- Issue #7117: On almost all platforms: float-to-string and string-to-float
4963 conversions within Python are now correctly rounded. Places these conversions
4964 occur include: str for floats and complex numbers; the float and complex
4965 constructors; old-style and new-style numeric formatting; serialization and
4966 deserialization of floats and complex numbers using marshal, pickle and json;
4967 parsing of float and imaginary literals in Python code; Decimal-to-float
4968 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004969
Georg Brandlba83f822010-03-14 09:50:54 +00004970 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4971 providing correctly-rounded strtod and dtoa C functions. This code is
4972 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4973 the C compiler. There may be a small number of platforms on which correct
4974 operation of this code cannot be guaranteed, so the code is not used: notably,
4975 this applies to platforms where the C double format is not IEEE 754 binary64,
4976 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4977 and Python's configure script is unable to determine how to change the FPU
4978 precision. On these platforms conversions use the platform strtod and dtoa,
4979 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004981- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4982 uses the correctly-rounded string <-> float conversions described above (when
4983 available), and so produces correctly rounded results that will display nicely
4984 under the float repr. There are two related small changes: (1) round now
4985 accepts any class with an ``__index__()`` method for its second argument (but
4986 no longer accepts floats for the second argument), and (2) an excessively
4987 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4988 raises an exception.

6573 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
6574 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6575 neither __int__ nor __long__, TypeError used to be raised (with a
6576 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
6577 struct.error in other cases.

6580 argument with an __int__ method can be packed, but use of this feature

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006774- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

6776 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6777 ``printf`` function, whereas PyString_FromFormat has an independent

Brett Cannon1eaf0742008-09-02 01:25:16 +00006875 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6876 for catch_warnings() also led to an improvement in the raising of a
6877 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006943What's New in Python 2.6 beta 3?
6944================================
6945
Barry Warsaw07a4a382008-08-21 01:15:08 +00006946*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006947
6948Core and Builtins
6949-----------------
6950
Guido van Rossumf8402962008-08-20 15:01:50 +00006951- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6952 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6953 extensions do not automatically benefit from the class attribute
6954 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6955 to their tp_flags field if they care. This is a backwards
6956 compatibility feature; in 3.0, all types will use the cache by
6957 default.
6958
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006959- Keyword arguments can now follow starred arguments. (``f(a, *args,
6960 keyword=23)`` is now valid syntax.)
6961
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006962- ctypes function pointers that are COM methods have a boolean True
6963 value again.
6964
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006965- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6966 by denying s# to parse objects that have a releasebuffer procedure,
6967 and introducing s*.
6968
Georg Brandl1e13ea92008-08-11 09:07:59 +00006969- Issue #3537: Fix an assertion failure when an empty but presized dict
6970 object was stored in the freelist.
6971
Mark Dickinsonb6467572008-08-04 21:30:09 +00006972- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6973 ValueError consistently across platforms.
6974
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006975- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6976 (64bit Unix, for example), unichr() would truncate its argument and return
6977 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6978
Neal Norwitze7d8be82008-07-31 17:17:14 +00006979- Apply security patches from Apple.
6980
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006981- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6982 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6983
Antoine Pitrou92f82162008-07-25 22:22:08 +00006984- Issue #1819: function calls with several named parameters are now on
6985 average 35% faster (as measured by pybench).
6986
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006987- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6988 the python debugger steps into a class statement: the free variables (local
6989 variables defined in an outer scope) would be deleted from the outer scope.
6990
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006991- Issue #2620: Overflow checking when allocating or reallocating memory
6992 was not always being done properly in some python types and extension
6993 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6994 all been updated to perform better checks and places in the code that
6995 would previously leak memory on the error path when such an allocation
6996 failed have been fixed.

6999-------
7000
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007001- Issue #3612: Added some missing basic types in ctypes.wintypes.
7002
Benjamin Petersone977ad42008-08-20 01:42:01 +00007003- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7004 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7005
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007006- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7007 version reported by these tools does not necessarily follow the python
7008 version numbering scheme, so the module is less strict when parsing it.
7009
Nick Coghlanf70385a2008-08-18 12:42:46 +00007010- Issue #2235: Added Py3k warnings for types which will become unhashable
7011 under the stricter __hash__ inheritance rules in 3.0. Several types
7012 which did not meet the rules for hash invariants and were already
7013 unhashable in 3.0 have now been explicitly flagged as unhashable in
7014 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7015 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7016
Brett Cannon88f801d2008-08-18 00:46:22 +00007017- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

Brett Cannon25c9d6a2008-08-17 22:10:11 +00007024- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7025
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007026- Issue #3575: Incremental decoder's decode function now takes bytearray
7027 by using 's*' instead of 't#'.
7028
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007029- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007030 fails unicode conversion on 2nd parameter. (windows only)
7031
Georg Brandl222e2082010-08-01 22:27:39 +00007032- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007033 in a redirect.
7034
Brett Cannonabe423e2008-08-16 21:47:07 +00007035- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007036 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007037
Facundo Batistaeb90b782008-08-16 14:44:07 +00007038- Issue #2776: fixed small issue when handling an URL with double slash
7039 after a 302 response in the case of not going through a proxy.
7040
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007041- Issue #2676: in the email package, content-type parsing was hanging on
7042 pathological input because of quadratic or exponential behaviour of a
7043 regular expression.
7044
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007045- Issue #3476: binary buffered reading through the new "io" library is now
7046 thread-safe.
7047
Brett Cannonbf3157b2008-08-14 05:00:03 +00007048- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7049 since mimetools itself is deprecated. Because modules are cached, all
7050 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7051
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007052- Issue #3134: shutil referenced undefined WindowsError symbol.
7053
Robert Schuppenies14646332008-08-10 11:01:53 +00007054- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7055 menu entries were not deleted.
7056
Brett Cannon83e81842008-08-09 23:30:55 +00007057- Copied the implementation of reduce() to _functools.reduce() to have a
7058 version that did not raise a DeprecationWarning under -3.
7059
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007060- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7061 a MemoryError rather than silently stop the iteration.
7062
Guido van Rossum59ce9012008-08-09 14:55:34 +00007063- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7064 to _sre.compile() will now be rejected. This should not affect anybody
7065 since the re.compile() function never generates invalid re-bytecode.
7066
Skip Montanaroa032bf42008-08-08 22:52:51 +00007067- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7068 upon first access it can be automatically initialized from the csv file if
7069 it wasn't initialized during instantiation.
7070
Brett Cannon3aa2a492008-08-06 22:28:09 +00007071- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7072 the reload() built-in has been removed.
7073
Brett Cannon7e30b672008-08-04 21:52:25 +00007074- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007075 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00007086 asking for a specific length. This problem only affected files opened
7087 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007088
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00007089- Issue #3449: Update decimal module to use most recent specification
7090 (v. 1.68) and tests (v. 2.58) from IBM.

7143-----------------
7144
Georg Brandl3e483f62008-07-16 22:57:41 +00007145- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7146 its methods now allow for items objects that can be converted to
7147 an integer using operator.index().
7148
Mark Dickinson64b7e502008-07-16 09:40:03 +00007149- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7150 produced a ValueError instead of giving the correct float.
7151
Eric Smitha5fa5a22008-07-16 00:11:49 +00007152- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7153 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7154
Mark Dickinson7103aa42008-07-15 19:08:33 +00007155- Issue #3008: the float type has a new instance method 'float.hex'
7156 and a new class method 'float.fromhex' to convert floating-point
7157 numbers to and from hexadecimal strings, respectively.
7158
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007159- Issue #2235: __hash__ is once again inherited by default. To allow
7160 collections.Hashable to remain meaningful in the presence of the
7161 default hash implementation (object.__hash__), it is now possible
7162 to explicit block inheritance of hash by setting __hash__=None at
7163 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7164 level.
7165
Nick Coghlanb028f502008-07-13 14:52:36 +00007166- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7167 the parent module cannot be found while performing an absolute import.
7168 This means that an incorrectly defined __package__ attribute will
7169 now only prevent relative imports in that module rather than causing
7170 all imports from that module to fail.
7171
Nick Coghlan14ff9942008-07-08 14:21:42 +00007172- Issue #2517: Allow unicode messages in Exceptions again by correctly

7181 threading.local: the first member set by a thread could be saved in
7182 another thread's dictionary.
7183
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007184- Issue #3004: Minor change to slice.indices(): the start and stop
7185 arguments are now treated identically, making the behaviour easier
7186 to describe and understand. For example, slice(None, -10,
7187 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7188 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7189 10, -1).
7190
Georg Brandl278fc502008-07-19 12:46:12 +00007191- Issue #3219: Calling a function with repeated keyword arguments,
7192 f(a=2, a=23), would not cause a syntax error. This was a regression
7193 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007194
Georg Brandl278fc502008-07-19 12:46:12 +00007195- Issue #2862: Make int and float freelist management consistent with
7196 other freelists. Changes their CompactFreeList apis into
7197 ClearFreeList apis and calls them via gc.collect().

7203 api functions without holding the GIL, which could lead to a fatal
7204 error when they failed.
7205
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007206- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007231- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7232 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007233 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007234 content-length. The problem had been corrected in the 2.4 branch, but never
7235 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00007250- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl3ee81df2008-05-17 18:14:43 +00007702- Issue #1631171: Re-implement the 'warnings' module in C (the
7703 original Python code has been kept as backup). This will allow for
7704 using the 'warning's machinery in such places as the parser where
7705 use of pure Python code is not possible. Both the ``showarning()``
7706 and ``formatwarning()`` gain an optional 'line' argument which is
7707 not called by default for backwards-compatibility reasons. Setting
7708 ``warnings.showwarning()`` to an implementation that lacks support
7709 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007772- Issue #2550: The approach used by client/server code for obtaining
7773 ports to listen on in network-oriented tests has been refined in an
7774 effort to facilitate running multiple instances of the entire
7775 regression test suite in parallel without issue.
7776 test_support.bind_port() has been fixed such that it will always
7777 return a unique port -- which wasn't always the case with the
7778 previous implementation, especially if socket options had been set
7779 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7780 new implementation of bind_port() will actually raise an exception
7781 if it is passed an AF_INET/SOCK_STREAM socket with either the
7782 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7783 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7784 the socket it's been passed. This currently only applies to
7785 Windows. This option prevents any other sockets from binding to the
7786 host/port we've bound to, thus removing the possibility of the
7787 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7788 when a second SOCK_STREAM socket binds and accepts to a host/port
7789 that's already been bound by another socket. The optional preferred
7790 port parameter to bind_port() has been removed. Under no
7791 circumstances should tests be hard coding ports!
7792
7793 test_support.find_unused_port() has also been introduced, which will
7794 pass a temporary socket object to bind_port() in order to obtain an
7795 unused port. The temporary socket object is then closed and
7796 deleted, and the port is returned. This method should only be used
7797 for obtaining an unused port in order to pass to an external program
7798 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7799 a parameter to a server-oriented class that doesn't give you direct
7800 access to the underlying socket used.
7801
7802 Finally, test_support.HOST has been introduced, which should be used
7803 for the host argument of any relevant socket calls (i.e. bind and
7804 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007805
7806 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007807 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007808 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7809 test_asynchat and test_socket_ssl.
7810
Georg Brandl3ee81df2008-05-17 18:14:43 +00007811 It is now possible for multiple instances of the regression test
7812 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008091- Added the future_builtins module, which contains hex() and oct().
8092 These are the PEP 3127 version of these functions, designed to be
8093 compatible with the hex() and oct() builtins from Python 3.0. They
8094 differ slightly in their output formats from the existing, unchanged
8095 Python 2.6 builtins. The expected usage of the future_builtins
8096 module is:
8097 from future_builtins import hex, oct
8098
Eric Smith7ef40bf2008-02-20 23:34:22 +00008099- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8100 exponents for exponents with absolute value < 100. Follows C99
8101 standard. This is a change on Windows, which would use 3 digits.
8102 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8103 so that any alterations it does to the resulting string will be
8104 available in stringlib/formatter.h (for float.__format__).
8105
Eric Smith5a3c1352008-02-19 13:21:56 +00008106- Implemented PEP 3101, Advanced String Formatting. This adds a new
8107 builtin format(); a format() method for str and unicode; a
8108 __format__() method to object, str, unicode, int, long, float, and
8109 datetime; the class string.Formatter; and the C API
8110 PyObject_Format().
8111
Georg Brandl3ee81df2008-05-17 18:14:43 +00008112- Fixed several potential crashes, all caused by specially crafted
8113 __del__ methods exploiting objects in temporarily inconsistent
8114 state.

8125 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008126
Georg Brandl3ee81df2008-05-17 18:14:43 +00008127- Issue #2045: Fix an infinite recursion triggered when printing a

8140
Georg Brandl3ee81df2008-05-17 18:14:43 +00008141- Issue #1983: Fixed return type of fork(), fork1() and forkpty()

Georg Brandl3ee81df2008-05-17 18:14:43 +00008157- Patch #1473257: generator objects gain a gi_code attribute. This is
8158 the same object as the func_code attribute of the function that
8159 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008160
Georg Brandl3ee81df2008-05-17 18:14:43 +00008161- Issue #1920: "while 0" statements were completely removed by the
8162 compiler, even in the presence of an "else" clause, which is
8163 supposed to be run when the condition is false. Now the compiler
8164 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008165

Georg Brandl14404b62008-01-19 19:27:05 +00008181- Issue #1679: "0x" was taken as a valid integer literal.
8182
Georg Brandl6caad7d2008-01-26 14:19:22 +00008183- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008184 added.
8185
Christian Heimesc94e2b52008-01-14 04:13:37 +00008186- sys.float_info / PyFloat_GetInfo: The floating point information
8187 object was converted from a dict to a specialized structseq object.
8188
Georg Brandl3ee81df2008-05-17 18:14:43 +00008189- Patch #1816: Added sys.flags structseq. It exposes the status of
8190 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008191
Georg Brandl3ee81df2008-05-17 18:14:43 +00008192- Objects/structseq.c: Implemented new structseq representation. The
8193 patch makes structseqs (e.g. the return value of os.stat) more
8194 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008195
Georg Brandl3ee81df2008-05-17 18:14:43 +00008196- Patch #1700288: added a type attribute cache that caches method
8197 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008198
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008199- Bug #1776: __import__() no longer accepts filenames on any platform.
8200 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008201
Georg Brandlaed6c662008-01-07 17:25:53 +00008202- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8203
Georg Brandl3ee81df2008-05-17 18:14:43 +00008204- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8205 envvar and sys.dont_write_bytecode attribute. All these can be set
8206 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008207
Georg Brandl3ee81df2008-05-17 18:14:43 +00008208- Improve some exception messages when Windows fails to load an
8209 extension module. Now we get for example '%1 is not a valid Win32
8210 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008211
Georg Brandl3ee81df2008-05-17 18:14:43 +00008212- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008214- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
8215 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008216
Christian Heimes0a8143f2007-12-18 23:22:54 +00008217- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008218 and INF. float("nan"), float("inf") and float("-inf") now work on
8219 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008220
Georg Brandl3ee81df2008-05-17 18:14:43 +00008221- Compiler now generates simpler and faster code for dictionary
8222 literals. The oparg for BUILD_MAP now indicates an estimated
8223 dictionary size. There is a new opcode, STORE_MAP, for adding
8224 entries to the dictionary.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00008234- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00008235 SystemError.
8236
Nick Coghlanef01d822007-12-03 12:55:17 +00008237- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00008253- Patch #1739468: Directories and zipfiles containing a __main__.py
8254 file can now be directly executed by passing their name to the
8255 interpreter. The directory/zipfile is automatically inserted as the
8256 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008257
Georg Brandl3ee81df2008-05-17 18:14:43 +00008258- Issue #1265: Fix a problem with sys.settrace, if the tracing
8259 function uses a generator expression when at the same time the
8260 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008261
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008262- sets and frozensets now have an isdisjoint() method.
8263
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008264- optimize the performance of builtin.sum().
8265
Neal Norwitz44f326e2007-10-05 05:29:17 +00008266- Fix warnings found by the new version of the Coverity checker.
8267
Georg Brandl21e99f42010-03-07 15:23:59 +00008268- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008269 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8270 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008271
Georg Brandl3ee81df2008-05-17 18:14:43 +00008272- Issue #1686386: Tuple's tp_repr did not take into account the
8273 possibility of having a self-referential tuple, which is possible
8274 from C code. Nor did object's tp_str consider that a type's tp_str
8275 could do something that could lead to an inifinite recursion.
8276 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8277 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008278
Georg Brandl3ee81df2008-05-17 18:14:43 +00008279- Issue #1164: It was possible to trigger deadlock when using the
8280 'print' statement to write to a file since the GIL was not released
8281 as needed. Now PyObject_Print() does the right thing along with
8282 various tp_print implementations of the built-in types and those in
8283 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008284
Georg Brandl3ee81df2008-05-17 18:14:43 +00008285- Issue #1147: Exceptions were directly allowing string exceptions in
8286 their throw() method even though string exceptions no longer
8287 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008288
Georg Brandl3ee81df2008-05-17 18:14:43 +00008289- Issue #1096: Prevent a segfault from getting the repr of a very
8290 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008291
Brett Cannon1e534b52007-09-07 04:18:30 +00008292- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008293 PyObject_Call() never calling back out to Python code to trigger
8294 recursion depth updates/checks. Required the creation of a static
8295 RuntimeError instance in case normalizing an exception put the
8296 recursion check value past its limit. Fixes crashers
8297 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008298
Georg Brandl3ee81df2008-05-17 18:14:43 +00008299- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00008312- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008313 __*__ attributes. (Some already existed, e.g., __doc__ and
8314 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008315
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008316- Add -3 option to the interpreter to warn about features that are
8317 deprecated and will be changed/removed in Python 3.0.
8318
Georg Brandl2134e752007-05-21 20:34:16 +00008319- Patch #1686487: you can now pass any mapping after '**' in function
8320 calls.
8321
Collin Winter62903052007-05-18 23:11:24 +00008322- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008323 "except E as target:". This is to provide forwards compatibility
8324 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008325
Brett Cannon229cee22007-05-05 01:34:02 +00008326- Deprecate BaseException.message as per PEP 352.
8327
Georg Brandl3ee81df2008-05-17 18:14:43 +00008328- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008329 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008330
Vinay Sajip8549ce32007-05-06 17:53:37 +00008331- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008332 setting a plain string, ie don't expand to single letter identifiers.
8333
Raymond Hettinger13936692007-04-11 18:40:58 +00008334- Request #1191699: Slices can now be pickled.
8335
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008336- Request #1193128: str.translate() now allows a None argument for
8337 translations that only remove characters without re-mapping the
8338 remaining characters.
8339
Georg Brandl5cb76c12007-03-21 09:00:39 +00008340- Patch #1682205: a TypeError while unpacking an iterable is no longer
8341 masked by a generic one with the message "unpack non-sequence".
8342
Neal Norwitzaa754b72007-03-21 06:39:48 +00008343- Remove unused file Python/fmod.c.
8344
Guido van Rossum143b5642007-03-23 04:58:42 +00008345- Bug #1683368: The object.__init__() and object.__new__() methods are
8346 now stricter in rejecting excess arguments. The only time when
8347 either allows excess arguments is when it is not overridden and the
8348 other one is. For backwards compatibility, when both are
8349 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008350 warning later). Also, type.__init__() insists on the same signature
8351 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008352
Georg Brandl3ee81df2008-05-17 18:14:43 +00008353- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8354 object to complex using its __complex__() method before falling back
8355 to the __float__() method. Therefore, the functions in the cmath
8356 module now can operate on objects that define a __complex__()
8357 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008358
Georg Brandl3ee81df2008-05-17 18:14:43 +00008359- Patch #1623563: allow __class__ assignment for classes with
8360 __slots__. The old and the new class are still required to have the
8361 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008362
Georg Brandl3ee81df2008-05-17 18:14:43 +00008363- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00008366- Patch #1462488: Python no longer segfaults when
8367 ``object.__reduce_ex__()`` is called with an object that is faking
8368 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00008369
Georg Brandl3ee81df2008-05-17 18:14:43 +00008370- Patch #1680015: Don't modify __slots__ tuple if it contains an

8374
Georg Brandl7b9c5552007-03-12 14:30:05 +00008375- Bug #1678647: write a newline after printing an exception in any
8376 case, even when converting the value to a string failed.
8377
Georg Brandl871f1bc2007-03-12 13:17:36 +00008378- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008379 its argument, if it exists. If not, it will work like before. This
8380 allows customizing the output of dir() in the presence of a
8381 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00008382
Collin Winter276887b2007-03-12 16:11:39 +00008383- Patch #922167: Python no longer segfaults when faced with infinitely
8384 self-recursive reload() calls (as reported by bug #742342).
8385
Georg Brandl3ee81df2008-05-17 18:14:43 +00008386- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00008389- Patch #1491866: change the complex() constructor to allow
8390 parthensized forms. This means complex(repr(x)) now works instead of
8391 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008392
Georg Brandlaa2321b2007-03-07 00:40:28 +00008393- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008394 makes the filenames the warning module prints much more sensible
8395 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008396
Georg Brandl49aafc92007-03-07 00:34:46 +00008397- Variant of patch #697613: don't exit the interpreter on a SystemExit
8398 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00008399 variable is given, but break into the interactive interpreter just
8400 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00008407
Georg Brandl0fca97a2007-03-05 22:28:08 +00008408- Patch #1674228: when assigning a slice (old-style), check for the
8409 sq_ass_slice instead of the sq_slice slot.
8410
Georg Brandl3ee81df2008-05-17 18:14:43 +00008411- When printing an unraisable error, don't print exceptions. before
8412 the name. This duplicates the behavior whening normally printing
8413 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00008414
Georg Brandl3ee81df2008-05-17 18:14:43 +00008415- Bug #1653736: Properly discard third argument to

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00008914- Added a timeout parameter to the constructor of other protocols
8915 (telnetlib, ftplib, smtplib and poplib). This is second part of the
8916 work started with create_connection() and timeout in httplib, and
8917 closes patch #723312.
8918

Georg Brandl3ee81df2008-05-17 18:14:43 +00008945 AttributeError instead of an IOError when the server's response
8946 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00008947

Georg Brandl3ee81df2008-05-17 18:14:43 +00008952- Patch #1429539: pdb now correctly initializes the __main__ module
8953 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00008954 correctly now.
8955

Georg Brandl3ee81df2008-05-17 18:14:43 +00008963- Patch #1530482: add pydoc.render_doc() which returns the

Georg Brandl9e6b4702007-03-13 18:15:41 +00008976- Patch #1581073: add a flag to textwrap that prevents the dropping of
8977 whitespace while wrapping.
8978
Georg Brandl92a6bae2007-03-13 17:43:32 +00008979- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008980 are set for invalid interpolation sequences that would lead to
8981 errors on reading back those values.

9024 returned string up to the first NUL character.

9035
Georg Brandl3ee81df2008-05-17 18:14:43 +00009036- unittest now verifies more of its assumptions. In particular,
9037 TestCase and TestSuite subclasses (not instances) are no longer
9038 accepted in TestSuite.addTest(). This should cause no
9039 incompatibility since it never made sense with ordinary subclasses
9040 -- the failure just occurred later, with a more cumbersome
9041 exception.

9051
Georg Brandl3ee81df2008-05-17 18:14:43 +00009052- Patch #1673619: setup.py identifies extension modules it doesn't

9406 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9407 silently miscode subclasses of those types. Now, it raises a

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009423- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00009424 time so that opening a database previously created with the DB_DUP
9425 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9426 opens. Specifically: dictionary assignment to a DB object will
9427 replace all values for a given key when the database allows
9428 duplicate values. DB users should use DB.put(k, v) when they want
9429 to store duplicates; not DB[k] = v.

9436 characters with ASCII value less than 32. Also, it correctly quotes
9437 dots only if they occur on a single line, as opposed to the previous
9438 behavior of quoting dots if they are the second character of any
9439 line.
