Raymond Hettinger20397532010-09-12 02:11:45 +0000844- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
845 This prevents user-created self-referencing ordered dictionaries from
846 becoming permanently uncollectable GC garbage. The downside is that
847 removing __del__ means that the internal doubly-linked list has to wait for
848 GC collection rather than freeing memory immediately when the refcnt drops
849 to zero.

857 to fetch the original errno, or to filter timeout errors. Now the
858 original error is re-raised.

1307
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001308- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1309 start byte and the continuation byte(s) are now considered invalid, instead
1310 of the number of bytes specified by the start byte.
1311 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1312 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1313 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
1314 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001322- Issue #8748: Fix two issues with comparisons between complex and integer
1323 objects. (1) The comparison could incorrectly return True in some cases
1324 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1325 (2) The comparison raised an OverflowError for large integers, leading
1326 to unpredictable exceptions when combining integers and complex objects
1327 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00001329- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00001714 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlba83f822010-03-14 09:50:54 +00002207 file position when calling `truncate()`. It would previously change the file
2208 position to the given argument, which goes against the tradition of

2212 class used to represent files stored inside an archive. The new
2213 implementation is significantly faster and can be wrapped in a

2215 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

2304-----------------
2305
Georg Brandlba83f822010-03-14 09:50:54 +00002306- The ``__complex__()`` method is now looked up on the class of instances to
2307 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00002309- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,

2311
Mark Dickinson1b34d252010-01-01 17:27:30 +00002312- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002313 DeprecationWarning when passed a float argument where an integer was expected.
2314 These functions and methods now raise TypeError instead. The majority of the
2315 effects of this change are in the extension modules, but some core functions
2316 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2317 and many unicode/str methods.

2331 of integers: the result of a/b is now correctly rounded for ints a and b (at
2332 least on IEEE 754 platforms), and in particular does not depend on the
2333 internal representation of a long.

2341
Georg Brandlba83f822010-03-14 09:50:54 +00002342 These executables now work properly with the arch(1) command: ``arch -ppc
2343 python`` will start a universal binary version of python in PPC mode (unlike
2344 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00002500- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2501 decimal string that's guaranteed to round back to x under correct rounding
2502 (with round-half-to-even rounding mode). Previously it gave a string based on
2503 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2504 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2505 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002506
Georg Brandlba83f822010-03-14 09:50:54 +00002507- Issue #7117: On almost all platforms: float-to-string and string-to-float
2508 conversions within Python are now correctly rounded. Places these conversions
2509 occur include: str for floats and complex numbers; the float and complex
2510 constructors; old-style and new-style numeric formatting; serialization and
2511 deserialization of floats and complex numbers using marshal, pickle and json;
2512 parsing of float and imaginary literals in Python code; Decimal-to-float
2513 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002514
Georg Brandlba83f822010-03-14 09:50:54 +00002515 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2516 providing correctly-rounded strtod and dtoa C functions. This code is
2517 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2518 the C compiler. There may be a small number of platforms on which correct
2519 operation of this code cannot be guaranteed, so the code is not used: notably,
2520 this applies to platforms where the C double format is not IEEE 754 binary64,
2521 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2522 and Python's configure script is unable to determine how to change the FPU
2523 precision. On these platforms conversions use the platform strtod and dtoa,
2524 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002526- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2527 uses the correctly-rounded string <-> float conversions described above (when
2528 available), and so produces correctly rounded results that will display nicely
2529 under the float repr. There are two related small changes: (1) round now
2530 accepts any class with an ``__index__()`` method for its second argument (but
2531 no longer accepts floats for the second argument), and (2) an excessively
2532 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2533 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00002675
Georg Brandlba83f822010-03-14 09:50:54 +00002676 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2677 (2) parsing of strings representing infinities and nans was locale aware; and
2678 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00002680- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2681 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2682 but with at least one decimal point and with a default precision
2683 of 12. Previously, the behavior the same but with a default precision of 6.
2684 This more closely matches ``str()``, and reduces surprises when adding
2685 alignment flags to the empty presentation type. This also affects the new
2686 complex.__format__ in the same way.
2687
2688- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00002884- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2885 file objects with closefd=False. The file descriptor is still kept open but
2886 the file object behaves like a closed file. The ``FileIO`` object also got a
2887 new readonly attribute ``closefd``.

2912 this code path is really executed because I cannot move to such directory on

Walter Dörwalded960ac2009-05-03 22:36:33 +00002938- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2939 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2940 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2941 of using the replace error handler in PyUnicode_DecodeUTF8().
2942
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002943- Issue #3739: The unicode-internal encoder now reports the number of characters

2945
Georg Brandlba83f822010-03-14 09:50:54 +00002946- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

2948 gives improved memory leak detection when running under Valgrind, while taking
2949 advantage of pymalloc at other times.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00004314- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
4315
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004316- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4317 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4318 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4319 ``printf`` function, whereas PyString_FromFormat has an independent
4320 implementation and uses "%zd" on all platforms for size_t values.
4321 This makes a difference on win64, where ``printf`` needs "%Id" to display
4322 64bit values.
4323
Benjamin Peterson97179b02008-09-09 20:55:01 +00004324- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00004327- Issue #3777: long() applied to a float object now always return a long
4328 object; previously an int would be returned for small values. the __long__
4329 method is allowed to return either an int or a long, but the behaviour of
4330 float objects should not change to respect backward compatibility.
4331
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004332- Issue #3751: str.rpartition would perform a left-partition when called with
4333 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00004338 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004339 was correctly parsed but parsing of subsequent arguments failed.
4340
Vinay Sajip35e3b032008-09-01 14:33:59 +00004341- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004342 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4343 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4344 when given a tuple of classes as second argument, were looking up
4345 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4346 type object.
4347
Neal Norwitz18aa3882008-08-24 05:04:52 +00004348- Fix crashes on memory allocation failure found with failmalloc.

4491-----------------
4492
Guido van Rossumf8402962008-08-20 15:01:50 +00004493- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4494 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4495 extensions do not automatically benefit from the class attribute
4496 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4497 to their tp_flags field if they care. This is a backwards
4498 compatibility feature; in 3.0, all types will use the cache by
4499 default.
4500
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004501- Keyword arguments can now follow starred arguments. (``f(a, *args,
4502 keyword=23)`` is now valid syntax.)
4503
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004504- ctypes function pointers that are COM methods have a boolean True
4505 value again.

4509 and introducing s*.
4510
Georg Brandl1e13ea92008-08-11 09:07:59 +00004511- Issue #3537: Fix an assertion failure when an empty but presized dict
4512 object was stored in the freelist.
4513
Mark Dickinsonb6467572008-08-04 21:30:09 +00004514- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4515 ValueError consistently across platforms.
4516
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004517- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4518 (64bit Unix, for example), unichr() would truncate its argument and return
4519 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Neal Norwitze7d8be82008-07-31 17:17:14 +00004521- Apply security patches from Apple.
4522
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004523- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

4525
Antoine Pitrou92f82162008-07-25 22:22:08 +00004526- Issue #1819: function calls with several named parameters are now on
4527 average 35% faster (as measured by pybench).
4528
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004529- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4530 the python debugger steps into a class statement: the free variables (local
4531 variables defined in an outer scope) would be deleted from the outer scope.
4532
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004533- Issue #2620: Overflow checking when allocating or reallocating memory
4534 was not always being done properly in some python types and extension
4535 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4536 all been updated to perform better checks and places in the code that
4537 would previously leak memory on the error path when such an allocation
4538 failed have been fixed.

Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004548- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4549 version reported by these tools does not necessarily follow the python
4550 version numbering scheme, so the module is less strict when parsing it.
4551
Nick Coghlanf70385a2008-08-18 12:42:46 +00004552- Issue #2235: Added Py3k warnings for types which will become unhashable
4553 under the stricter __hash__ inheritance rules in 3.0. Several types
4554 which did not meet the rules for hash invariants and were already
4555 unhashable in 3.0 have now been explicitly flagged as unhashable in
4556 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4557 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4558

4588 thread-safe.
4589
Brett Cannonbf3157b2008-08-14 05:00:03 +00004590- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4591 since mimetools itself is deprecated. Because modules are cached, all
4592 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4593

4603 a MemoryError rather than silently stop the iteration.
4604

4606 to _sre.compile() will now be rejected. This should not affect anybody
4607 since the re.compile() function never generates invalid re-bytecode.
4608
Skip Montanaroa032bf42008-08-08 22:52:51 +00004609- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

4611 it wasn't initialized during instantiation.
4612
Brett Cannon3aa2a492008-08-06 22:28:09 +00004613- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4614 the reload() built-in has been removed.
4615
Brett Cannon7e30b672008-08-04 21:52:25 +00004616- Changed code in the following modules/packages to remove warnings raised

4625 raised an AttributeError.
4626

Antoine Pitroude781a42008-08-09 12:43:23 +00004628 asking for a specific length. This problem only affected files opened
4629 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004630

4655 file name rather than a ZipInfo instance, so files are extracted with
4656 mode 0600 rather than 000 under Unix.
4657
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004658- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

4671 interaction with the tp_hash slot (added in 2.6b2) are now documented
4672
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004673- Issue #643841: The language reference now provides more detailed
4674 coverage of the lookup process for special methods. The disclaimers
4675 regarding lack of coverage of new-style classes have also been
4676 removed, since the coverage is now fairly reasonable.

4680================================
4681
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004682*Release date: 17-Jul-2008*
4683
Raymond Hettingere3ae6552008-06-20 04:18:15 +00004684Core and Builtins
4685-----------------
4686
Georg Brandl3e483f62008-07-16 22:57:41 +00004687- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4688 its methods now allow for items objects that can be converted to
4689 an integer using operator.index().
4690
Mark Dickinson64b7e502008-07-16 09:40:03 +00004691- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4692 produced a ValueError instead of giving the correct float.
4693
Eric Smitha5fa5a22008-07-16 00:11:49 +00004694- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4695 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4696
Mark Dickinson7103aa42008-07-15 19:08:33 +00004697- Issue #3008: the float type has a new instance method 'float.hex'
4698 and a new class method 'float.fromhex' to convert floating-point
4699 numbers to and from hexadecimal strings, respectively.
4700
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004701- Issue #2235: __hash__ is once again inherited by default. To allow
4702 collections.Hashable to remain meaningful in the presence of the
4703 default hash implementation (object.__hash__), it is now possible
4704 to explicit block inheritance of hash by setting __hash__=None at
4705 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4706 level.
4707
Nick Coghlanb028f502008-07-13 14:52:36 +00004708- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4709 the parent module cannot be found while performing an absolute import.
4710 This means that an incorrectly defined __package__ attribute will
4711 now only prevent relative imports in that module rather than causing
4712 all imports from that module to fail.
4713
Nick Coghlan14ff9942008-07-08 14:21:42 +00004714- Issue #2517: Allow unicode messages in Exceptions again by correctly
4715 bypassing the instance dictionary when looking up __unicode__ on
4716 new-style classes.
4717
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004718- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4719 set to a custom object whose write() method happens to install
4720 another file in sys.stdout.
4721
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004722- Issue #3088: Corrected a race condition in classes derived from
4723 threading.local: the first member set by a thread could be saved in
4724 another thread's dictionary.
4725
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004726- Issue #3004: Minor change to slice.indices(): the start and stop
4727 arguments are now treated identically, making the behaviour easier
4728 to describe and understand. For example, slice(None, -10,
4729 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4730 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4731 10, -1).
4732
Georg Brandl278fc502008-07-19 12:46:12 +00004733- Issue #3219: Calling a function with repeated keyword arguments,
4734 f(a=2, a=23), would not cause a syntax error. This was a regression
4735 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004736
Georg Brandl278fc502008-07-19 12:46:12 +00004737- Issue #2862: Make int and float freelist management consistent with
4738 other freelists. Changes their CompactFreeList apis into
4739 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00004744- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4745 api functions without holding the GIL, which could lead to a fatal
4746 error when they failed.
4747
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004748- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004773- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4774 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004775 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004776 content-length. The problem had been corrected in the 2.4 branch, but never
4777 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004792- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

4794
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004795- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

5184 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005185 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005186
5187 This is controlled by the configure argument ``--with-universal-archs``:
5188
5189 - ``--with-universal-archs=all``: install 4-way universal
5190
5191 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5192
5193 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5194
5195 This option should be used in combination with ``--enable-universalsdk=``.
5196
5197 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00005247- Issue #1631171: Re-implement the 'warnings' module in C (the
5248 original Python code has been kept as backup). This will allow for
5249 using the 'warning's machinery in such places as the parser where
5250 use of pure Python code is not possible. Both the ``showarning()``
5251 and ``formatwarning()`` gain an optional 'line' argument which is
5252 not called by default for backwards-compatibility reasons. Setting
5253 ``warnings.showwarning()`` to an implementation that lacks support
5254 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005317- Issue #2550: The approach used by client/server code for obtaining
5318 ports to listen on in network-oriented tests has been refined in an
5319 effort to facilitate running multiple instances of the entire
5320 regression test suite in parallel without issue.
5321 test_support.bind_port() has been fixed such that it will always
5322 return a unique port -- which wasn't always the case with the
5323 previous implementation, especially if socket options had been set
5324 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5325 new implementation of bind_port() will actually raise an exception
5326 if it is passed an AF_INET/SOCK_STREAM socket with either the
5327 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5328 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5329 the socket it's been passed. This currently only applies to
5330 Windows. This option prevents any other sockets from binding to the
5331 host/port we've bound to, thus removing the possibility of the
5332 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5333 when a second SOCK_STREAM socket binds and accepts to a host/port
5334 that's already been bound by another socket. The optional preferred
5335 port parameter to bind_port() has been removed. Under no
5336 circumstances should tests be hard coding ports!
5337
5338 test_support.find_unused_port() has also been introduced, which will
5339 pass a temporary socket object to bind_port() in order to obtain an
5340 unused port. The temporary socket object is then closed and
5341 deleted, and the port is returned. This method should only be used
5342 for obtaining an unused port in order to pass to an external program
5343 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5344 a parameter to a server-oriented class that doesn't give you direct
5345 access to the underlying socket used.
5346
5347 Finally, test_support.HOST has been introduced, which should be used
5348 for the host argument of any relevant socket calls (i.e. bind and
5349 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005350
5351 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005352 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005353 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5354 test_asynchat and test_socket_ssl.
5355
Georg Brandl3ee81df2008-05-17 18:14:43 +00005356 It is now possible for multiple instances of the regression test
5357 suite to run in parallel without issue.

Georg Brandl222e2082010-08-01 22:27:39 +00005634 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00005635
Eric Smitha73fbe72008-02-23 03:09:44 +00005636- Added the future_builtins module, which contains hex() and oct().
5637 These are the PEP 3127 version of these functions, designed to be
5638 compatible with the hex() and oct() builtins from Python 3.0. They
5639 differ slightly in their output formats from the existing, unchanged
5640 Python 2.6 builtins. The expected usage of the future_builtins
5641 module is:
5642 from future_builtins import hex, oct
5643
Eric Smith7ef40bf2008-02-20 23:34:22 +00005644- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5645 exponents for exponents with absolute value < 100. Follows C99
5646 standard. This is a change on Windows, which would use 3 digits.
5647 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5648 so that any alterations it does to the resulting string will be
5649 available in stringlib/formatter.h (for float.__format__).
5650
Eric Smith5a3c1352008-02-19 13:21:56 +00005651- Implemented PEP 3101, Advanced String Formatting. This adds a new
5652 builtin format(); a format() method for str and unicode; a
5653 __format__() method to object, str, unicode, int, long, float, and
5654 datetime; the class string.Formatter; and the C API
5655 PyObject_Format().
5656
Georg Brandl3ee81df2008-05-17 18:14:43 +00005657- Fixed several potential crashes, all caused by specially crafted
5658 __del__ methods exploiting objects in temporarily inconsistent
5659 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005660
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005661- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005662 prevent a possible crash: an Abstract Base Class would try to access
5663 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005664
Georg Brandl3ee81df2008-05-17 18:14:43 +00005665- Fixed repr() and str() of complex numbers with infinity or nan as
5666 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00005667
Georg Brandl3ee81df2008-05-17 18:14:43 +00005668- Clear all free lists during a gc.collect() of the highest generation
5669 in order to allow pymalloc to free more arenas. Python may give back
5670 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005671
Georg Brandl3ee81df2008-05-17 18:14:43 +00005672- Issue #2045: Fix an infinite recursion triggered when printing a
5673 subclass of collections.defaultdict, if its default_factory is set
5674 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005675
Christian Heimesf75dbef2008-02-08 00:11:31 +00005676- Fixed a minor memory leak in dictobject.c. The content of the free
5677 list was not freed on interpreter shutdown.
5678
Georg Brandl21e99f42010-03-07 15:23:59 +00005679- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005680 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005681
Georg Brandl3ee81df2008-05-17 18:14:43 +00005682- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5683 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005684 to compact the internal free lists of pre-allocted ints and floats.
5685
Georg Brandl3ee81df2008-05-17 18:14:43 +00005686- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5687 calls. Python expected the return type int but the fork familie
5688 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005689
Georg Brandl3ee81df2008-05-17 18:14:43 +00005690- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5691 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005692
Georg Brandl3ee81df2008-05-17 18:14:43 +00005693- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5694 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005695
Georg Brandl3ee81df2008-05-17 18:14:43 +00005696- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
5697 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00005698
Georg Brandl3ee81df2008-05-17 18:14:43 +00005699- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5700 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005701
Georg Brandl3ee81df2008-05-17 18:14:43 +00005702- Patch #1473257: generator objects gain a gi_code attribute. This is
5703 the same object as the func_code attribute of the function that
5704 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005705
Georg Brandl3ee81df2008-05-17 18:14:43 +00005706- Issue #1920: "while 0" statements were completely removed by the
5707 compiler, even in the presence of an "else" clause, which is
5708 supposed to be run when the condition is false. Now the compiler
5709 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005710
Guido van Rossumeead05f2008-01-24 18:21:02 +00005711- A few crashers fixed: weakref_in_del.py (issue #1377858);
5712 loosing_dict_ref.py (issue #1303614, test67.py);
5713 borrowed_ref_[34].py (not in tracker).
5714
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005715- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005716 suppressed while an extension is loaded by calling SetErrorMode in
5717 dynload_win.c. The error is still reported properly.
5718
Georg Brandl3ee81df2008-05-17 18:14:43 +00005719- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005720 several extension methods and modules do not work without unicode
5721 support.
5722
Georg Brandl26543b12008-01-21 18:36:51 +00005723- Issue #1882: when compiling code from a string, encoding cookies in the
5724 second line of code were not always recognized correctly.
5725
Georg Brandl14404b62008-01-19 19:27:05 +00005726- Issue #1679: "0x" was taken as a valid integer literal.
5727
Georg Brandl6caad7d2008-01-26 14:19:22 +00005728- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005729 added.
5730
Christian Heimesc94e2b52008-01-14 04:13:37 +00005731- sys.float_info / PyFloat_GetInfo: The floating point information
5732 object was converted from a dict to a specialized structseq object.
5733
Georg Brandl3ee81df2008-05-17 18:14:43 +00005734- Patch #1816: Added sys.flags structseq. It exposes the status of
5735 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005736
Georg Brandl3ee81df2008-05-17 18:14:43 +00005737- Objects/structseq.c: Implemented new structseq representation. The
5738 patch makes structseqs (e.g. the return value of os.stat) more
5739 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005740
Georg Brandl3ee81df2008-05-17 18:14:43 +00005741- Patch #1700288: added a type attribute cache that caches method
5742 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005743
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005744- Bug #1776: __import__() no longer accepts filenames on any platform.
5745 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005746
Georg Brandlaed6c662008-01-07 17:25:53 +00005747- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5748
Georg Brandl3ee81df2008-05-17 18:14:43 +00005749- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5750 envvar and sys.dont_write_bytecode attribute. All these can be set
5751 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005752
Georg Brandl3ee81df2008-05-17 18:14:43 +00005753- Improve some exception messages when Windows fails to load an
5754 extension module. Now we get for example '%1 is not a valid Win32
5755 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005756
Georg Brandl3ee81df2008-05-17 18:14:43 +00005757- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005759- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5760 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005761
Christian Heimes0a8143f2007-12-18 23:22:54 +00005762- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005763 and INF. float("nan"), float("inf") and float("-inf") now work on
5764 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005765
Georg Brandl3ee81df2008-05-17 18:14:43 +00005766- Compiler now generates simpler and faster code for dictionary
5767 literals. The oparg for BUILD_MAP now indicates an estimated
5768 dictionary size. There is a new opcode, STORE_MAP, for adding
5769 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005803- Issue #1265: Fix a problem with sys.settrace, if the tracing
5804 function uses a generator expression when at the same time the
5805 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005806
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005807- sets and frozensets now have an isdisjoint() method.
5808
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005809- optimize the performance of builtin.sum().

5812
Georg Brandl21e99f42010-03-07 15:23:59 +00005813- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005814 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5815 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005816
Georg Brandl3ee81df2008-05-17 18:14:43 +00005817- Issue #1686386: Tuple's tp_repr did not take into account the
5818 possibility of having a self-referential tuple, which is possible
5819 from C code. Nor did object's tp_str consider that a type's tp_str
5820 could do something that could lead to an inifinite recursion.
5821 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5822 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005823
Georg Brandl3ee81df2008-05-17 18:14:43 +00005824- Issue #1164: It was possible to trigger deadlock when using the
5825 'print' statement to write to a file since the GIL was not released
5826 as needed. Now PyObject_Print() does the right thing along with
5827 various tp_print implementations of the built-in types and those in
5828 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005829
Georg Brandl3ee81df2008-05-17 18:14:43 +00005830- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00005837- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005838 PyObject_Call() never calling back out to Python code to trigger
5839 recursion depth updates/checks. Required the creation of a static
5840 RuntimeError instance in case normalizing an exception put the
5841 recursion check value past its limit. Fixes crashers
5842 infinite_rec_(1|2|4|5).py.

5863
Georg Brandl2134e752007-05-21 20:34:16 +00005864- Patch #1686487: you can now pass any mapping after '**' in function
5865 calls.
5866
Collin Winter62903052007-05-18 23:11:24 +00005867- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005868 "except E as target:". This is to provide forwards compatibility
5869 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005876- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005877 setting a plain string, ie don't expand to single letter identifiers.

5883 remaining characters.
5884
Georg Brandl5cb76c12007-03-21 09:00:39 +00005885- Patch #1682205: a TypeError while unpacking an iterable is no longer

Guido van Rossum143b5642007-03-23 04:58:42 +00005890- Bug #1683368: The object.__init__() and object.__new__() methods are
5891 now stricter in rejecting excess arguments. The only time when
5892 either allows excess arguments is when it is not overridden and the
5893 other one is. For backwards compatibility, when both are
5894 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005895 warning later). Also, type.__init__() insists on the same signature
5896 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005898- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5899 object to complex using its __complex__() method before falling back
5900 to the __float__() method. Therefore, the functions in the cmath
5901 module now can operate on objects that define a __complex__()
5902 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00005920- Bug #1678647: write a newline after printing an exception in any
5921 case, even when converting the value to a string failed.
5922
Georg Brandl871f1bc2007-03-12 13:17:36 +00005923- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005924 its argument, if it exists. If not, it will work like before. This
5925 allows customizing the output of dir() in the presence of a
5926 __getattr__().

5936 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00005938- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005939 makes the filenames the warning module prints much more sensible
5940 when a PYTHONSTARTUP file is used.

5954 sq_ass_slice instead of the sq_slice slot.
5955
Georg Brandl3ee81df2008-05-17 18:14:43 +00005956- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00006059 generator expressions (x for x, in ... ) works again. Fixing this
6060 problem required changing the .pyc magic number. This means that
6061 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006868- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6869 with RFC 3207 and forgets any knowledge obtained from the server not
6870 obtained from the TLS negotiation itself. Patch contributed by Bill
6871 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006872
Georg Brandl3ee81df2008-05-17 18:14:43 +00006873- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006874 that the SMTP.starttls() caller no longer needs to call ehlo()
6875 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006876 does not claim to support starttls. Adds the
6877 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
6878 Fenner.

6958 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6959 silently miscode subclasses of those types. Now, it raises a
6960 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006961

Georg Brandl3ee81df2008-05-17 18:14:43 +00006976 time so that opening a database previously created with the DB_DUP
6977 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6978 opens. Specifically: dictionary assignment to a DB object will
6979 replace all values for a given key when the database allows
6980 duplicate values. DB users should use DB.put(k, v) when they want
6981 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006982

6988 characters with ASCII value less than 32. Also, it correctly quotes
6989 dots only if they occur on a single line, as opposed to the previous
6990 behavior of quoting dots if they are the second character of any
6991 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006992

Georg Brandl3ee81df2008-05-17 18:14:43 +00007397- Removed the macfs module. It had been deprecated since Python 2.5.
7398 This lead to the deprecation of macostools.touched() as it relied
7399 solely on macfs and was a no-op under OS X.
