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

470 GC collection rather than freeing memory immediately when the refcnt drops
471 to zero.

928
Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000929- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
930 start byte and the continuation byte(s) are now considered invalid, instead
931 of the number of bytes specified by the start byte.
932 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
933 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
934 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
935 Previous versions returned a single u'\ufffd'.
936
Mark Dickinson23f0d6b2010-06-05 11:52:24 +0000937- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +0000938 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
939 arises from the "Overriding __eq__ blocks inheritance ..." warning
940 when turned into an exception: in this case the exception simply
941 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +0000942
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000943- Issue #8748: Fix two issues with comparisons between complex and integer
944 objects. (1) The comparison could incorrectly return True in some cases
945 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
946 (2) The comparison raised an OverflowError for large integers, leading
947 to unpredictable exceptions when combining integers and complex objects
948 in sets or dicts.
949
Mark Dickinson81336372010-05-30 12:12:25 +0000950- Issue #5211: Implicit coercion for the complex type is now completely
951 removed. (Coercion for arithmetic operations was already removed in 2.7
952 alpha 4, but coercion for rich comparisons was accidentally left in.)
953
Victor Stinnerc49dfcc2010-05-25 22:30:32 +0000954- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
955 and error handler, instead of writing to the C stderr file in utf-8
956
Georg Brandlfee0f442010-05-22 21:26:21 +0000957- Issue #7902: When using explicit relative import syntax, don't try implicit
958 relative import semantics.
Brett Cannoneb3cd302010-05-20 18:37:55 +0000959

961 from another thread. Patch by Daniel Stutzbach.

Georg Brandlfee0f442010-05-22 21:26:21 +0000969- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows embedders
970 of the interpreter to set sys.argv without also modifying sys.path. This
971 helps fix `CVE-2008-5983

1088 non-float non-integer argument is now converted to an integer (if possible)
1089 using its __int__ method. Previously, only small arguments were treated this
1090 way; larger arguments (those whose __int__ was outside the range of a C long)

1142 operation raises multiple signals and more than one of those signals is
1143 trapped, the specification determines the order in which the signals should be

1318 changed.

Georg Brandlfee0f442010-05-22 21:26:21 +00001330- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1331 with a non-empty format string. This is an effort to future-proof user
1332 code. If a derived class does not currently implement __format__ but later
1333 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001334 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001335 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001385- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1386 InvalidOperation instead of returning False. (Comparisons involving a quiet
1387 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1388 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00001390- Issue #2531: Comparison operations between floats and Decimal instances now
1391 return a result based on the numeric values of the operands; previously they
1392 returned an arbitrary result based on the relative ordering of id(float) and
1393 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00001407- Comparisons using one of <, <=, >, >= between a complex instance and a
1408 Fractions instance now raise TypeError instead of returning True/False. This
1409 makes Fraction <=> complex comparisons consistent with int <=> complex, float

Georg Brandlba83f822010-03-14 09:50:54 +00001772- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
1773 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1774 returning NULL. The macro now returns a statically allocated empty string
1775 instead.

1785 strings,
1786 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
1787 numeric strings corresponding to subnormal values,
1788 (3) a memory leak for some values large enough to cause overflow, and
1789 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00001820- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00001821 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00001822 Also, raise ValueError rather than TypeError when an unknown TIPC address
1823 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001827- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001828 file position when calling `truncate()`. It would previously change the file
1829 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001830 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1831
Georg Brandlba83f822010-03-14 09:50:54 +00001832- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1833 class used to represent files stored inside an archive. The new
1834 implementation is significantly faster and can be wrapped in a
1835 ``io.BufferedReader`` object for more speedups. It also solves an issue
1836 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
1837 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00001847- Issue #7748: Since unicode values are supported for some metadata options in
1848 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1849 encoded string for them. This ensures that the upload and register commands
1850 send the correct values to PyPI without any error.

1935 These functions and methods now raise TypeError instead. The majority of the
1936 effects of this change are in the extension modules, but some core functions
1937 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1938 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00002121- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2122 decimal string that's guaranteed to round back to x under correct rounding
2123 (with round-half-to-even rounding mode). Previously it gave a string based on
2124 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2125 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2126 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00002128- Issue #7117: On almost all platforms: float-to-string and string-to-float
2129 conversions within Python are now correctly rounded. Places these conversions
2130 occur include: str for floats and complex numbers; the float and complex
2131 constructors; old-style and new-style numeric formatting; serialization and
2132 deserialization of floats and complex numbers using marshal, pickle and json;
2133 parsing of float and imaginary literals in Python code; Decimal-to-float
2134 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002135
Georg Brandlba83f822010-03-14 09:50:54 +00002136 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2137 providing correctly-rounded strtod and dtoa C functions. This code is
2138 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2139 the C compiler. There may be a small number of platforms on which correct
2140 operation of this code cannot be guaranteed, so the code is not used: notably,
2141 this applies to platforms where the C double format is not IEEE 754 binary64,
2142 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2143 and Python's configure script is unable to determine how to change the FPU
2144 precision. On these platforms conversions use the platform strtod and dtoa,
2145 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002147- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2148 uses the correctly-rounded string <-> float conversions described above (when
2149 available), and so produces correctly rounded results that will display nicely
2150 under the float repr. There are two related small changes: (1) round now
2151 accepts any class with an ``__index__()`` method for its second argument (but
2152 no longer accepts floats for the second argument), and (2) an excessively
2153 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2154 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002372 untrackable objects are not tracked by the garbage collector. This can reduce
2373 the size of collections and therefore the garbage collection overhead on

Georg Brandlba83f822010-03-14 09:50:54 +00002447- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2448 existing .py counterpart, override the co_filename attributes of all code

2504
Georg Brandlba83f822010-03-14 09:50:54 +00002505- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2506 file objects with closefd=False. The file descriptor is still kept open but
2507 the file object behaves like a closed file. The ``FileIO`` object also got a

2533 this code path is really executed because I cannot move to such directory on

Walter Dörwalded960ac2009-05-03 22:36:33 +00002559- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2560 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Walter Dörwald726ba8e2009-05-06 14:32:35 +00002564- Issue #3739: The unicode-internal encoder now reports the number of characters

3939 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3940 ``printf`` function, whereas PyString_FromFormat has an independent

Brett Cannon672237d2008-09-09 00:49:16 +00004012 return a list or None rather than a custom object.
4013

Brett Cannon1eaf0742008-09-02 01:25:16 +00004038 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4039 for catch_warnings() also led to an improvement in the raising of a
4040 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004106What's New in Python 2.6 beta 3?
4107================================
4108
Barry Warsaw07a4a382008-08-21 01:15:08 +00004109*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004110
4111Core and Builtins
4112-----------------
4113
Guido van Rossumf8402962008-08-20 15:01:50 +00004114- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4115 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4116 extensions do not automatically benefit from the class attribute
4117 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4118 to their tp_flags field if they care. This is a backwards
4119 compatibility feature; in 3.0, all types will use the cache by
4120 default.
4121
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004122- Keyword arguments can now follow starred arguments. (``f(a, *args,
4123 keyword=23)`` is now valid syntax.)
4124
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004125- ctypes function pointers that are COM methods have a boolean True
4126 value again.
4127
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004128- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4129 by denying s# to parse objects that have a releasebuffer procedure,
4130 and introducing s*.
4131
Georg Brandl1e13ea92008-08-11 09:07:59 +00004132- Issue #3537: Fix an assertion failure when an empty but presized dict
4133 object was stored in the freelist.
4134
Mark Dickinsonb6467572008-08-04 21:30:09 +00004135- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4136 ValueError consistently across platforms.
4137
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004138- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4139 (64bit Unix, for example), unichr() would truncate its argument and return
4140 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4141
Neal Norwitze7d8be82008-07-31 17:17:14 +00004142- Apply security patches from Apple.
4143
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004144- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4145 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4146
Antoine Pitrou92f82162008-07-25 22:22:08 +00004147- Issue #1819: function calls with several named parameters are now on
4148 average 35% faster (as measured by pybench).
4149
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004150- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4151 the python debugger steps into a class statement: the free variables (local
4152 variables defined in an outer scope) would be deleted from the outer scope.
4153
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004154- Issue #2620: Overflow checking when allocating or reallocating memory
4155 was not always being done properly in some python types and extension
4156 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4157 all been updated to perform better checks and places in the code that
4158 would previously leak memory on the error path when such an allocation
4159 failed have been fixed.

4162-------
4163
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004164- Issue #3612: Added some missing basic types in ctypes.wintypes.
4165
Benjamin Petersone977ad42008-08-20 01:42:01 +00004166- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4167 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4168
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004169- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4170 version reported by these tools does not necessarily follow the python
4171 version numbering scheme, so the module is less strict when parsing it.
4172
Nick Coghlanf70385a2008-08-18 12:42:46 +00004173- Issue #2235: Added Py3k warnings for types which will become unhashable
4174 under the stricter __hash__ inheritance rules in 3.0. Several types
4175 which did not meet the rules for hash invariants and were already
4176 unhashable in 3.0 have now been explicitly flagged as unhashable in
4177 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4178 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4179
Brett Cannon88f801d2008-08-18 00:46:22 +00004180- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4181 imported into the module but exposed as part of the module's API.
4182
Brett Cannon7b96f072008-08-18 00:41:11 +00004183- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4184
Brett Cannon46225e72008-08-18 00:36:52 +00004185- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004187- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4188
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004189- Issue #3575: Incremental decoder's decode function now takes bytearray
4190 by using 's*' instead of 't#'.
4191
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004192- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004193 fails unicode conversion on 2nd parameter. (windows only)
4194
Georg Brandl222e2082010-08-01 22:27:39 +00004195- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004196 in a redirect.
4197
Brett Cannonabe423e2008-08-16 21:47:07 +00004198- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004199 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004200
Facundo Batistaeb90b782008-08-16 14:44:07 +00004201- Issue #2776: fixed small issue when handling an URL with double slash
4202 after a 302 response in the case of not going through a proxy.
4203
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004204- Issue #2676: in the email package, content-type parsing was hanging on
4205 pathological input because of quadratic or exponential behaviour of a
4206 regular expression.
4207
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004208- Issue #3476: binary buffered reading through the new "io" library is now
4209 thread-safe.
4210
Brett Cannonbf3157b2008-08-14 05:00:03 +00004211- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4212 since mimetools itself is deprecated. Because modules are cached, all
4213 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4214
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004215- Issue #3134: shutil referenced undefined WindowsError symbol.
4216
Robert Schuppenies14646332008-08-10 11:01:53 +00004217- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4218 menu entries were not deleted.
4219
Brett Cannon83e81842008-08-09 23:30:55 +00004220- Copied the implementation of reduce() to _functools.reduce() to have a
4221 version that did not raise a DeprecationWarning under -3.
4222
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004223- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4224 a MemoryError rather than silently stop the iteration.
4225
Guido van Rossum59ce9012008-08-09 14:55:34 +00004226- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4227 to _sre.compile() will now be rejected. This should not affect anybody
4228 since the re.compile() function never generates invalid re-bytecode.
4229
Skip Montanaroa032bf42008-08-08 22:52:51 +00004230- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4231 upon first access it can be automatically initialized from the csv file if
4232 it wasn't initialized during instantiation.
4233
Brett Cannon3aa2a492008-08-06 22:28:09 +00004234- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4235 the reload() built-in has been removed.
4236
Brett Cannon7e30b672008-08-04 21:52:25 +00004237- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004238 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

4241 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
4242 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
4243 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00004244

Antoine Pitroude781a42008-08-09 12:43:23 +00004249 asking for a specific length. This problem only affected files opened
4250 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004251
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00004252- Issue #3449: Update decimal module to use most recent specification
4253 (v. 1.68) and tests (v. 2.58) from IBM.

4292 interaction with the tp_hash slot (added in 2.6b2) are now documented
4293
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004294- Issue #643841: The language reference now provides more detailed

4306-----------------
4307
Georg Brandl3e483f62008-07-16 22:57:41 +00004308- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4309 its methods now allow for items objects that can be converted to
4310 an integer using operator.index().
4311
Mark Dickinson64b7e502008-07-16 09:40:03 +00004312- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4313 produced a ValueError instead of giving the correct float.
4314
Eric Smitha5fa5a22008-07-16 00:11:49 +00004315- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4316 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4317
Mark Dickinson7103aa42008-07-15 19:08:33 +00004318- Issue #3008: the float type has a new instance method 'float.hex'
4319 and a new class method 'float.fromhex' to convert floating-point
4320 numbers to and from hexadecimal strings, respectively.
4321
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004322- Issue #2235: __hash__ is once again inherited by default. To allow
4323 collections.Hashable to remain meaningful in the presence of the
4324 default hash implementation (object.__hash__), it is now possible
4325 to explicit block inheritance of hash by setting __hash__=None at
4326 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4327 level.
4328
Nick Coghlanb028f502008-07-13 14:52:36 +00004329- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4330 the parent module cannot be found while performing an absolute import.
4331 This means that an incorrectly defined __package__ attribute will
4332 now only prevent relative imports in that module rather than causing
4333 all imports from that module to fail.
4334
Nick Coghlan14ff9942008-07-08 14:21:42 +00004335- Issue #2517: Allow unicode messages in Exceptions again by correctly

4344 threading.local: the first member set by a thread could be saved in
4345 another thread's dictionary.
4346
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004347- Issue #3004: Minor change to slice.indices(): the start and stop
4348 arguments are now treated identically, making the behaviour easier
4349 to describe and understand. For example, slice(None, -10,
4350 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4351 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4352 10, -1).
4353
Georg Brandl278fc502008-07-19 12:46:12 +00004354- Issue #3219: Calling a function with repeated keyword arguments,
4355 f(a=2, a=23), would not cause a syntax error. This was a regression
4356 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004357
Georg Brandl278fc502008-07-19 12:46:12 +00004358- Issue #2862: Make int and float freelist management consistent with
4359 other freelists. Changes their CompactFreeList apis into
4360 ClearFreeList apis and calls them via gc.collect().

4366 api functions without holding the GIL, which could lead to a fatal
4367 error when they failed.
4368
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004369- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004394- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4395 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004396 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004397 content-length. The problem had been corrected in the 2.4 branch, but never
4398 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004413- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4414 handling is now the same as that of other special attributes like __name__).

Georg Brandl3ee81df2008-05-17 18:14:43 +00004868- Issue #1631171: Re-implement the 'warnings' module in C (the
4869 original Python code has been kept as backup). This will allow for
4870 using the 'warning's machinery in such places as the parser where
4871 use of pure Python code is not possible. Both the ``showarning()``
4872 and ``formatwarning()`` gain an optional 'line' argument which is
4873 not called by default for backwards-compatibility reasons. Setting
4874 ``warnings.showwarning()`` to an implementation that lacks support
4875 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004938- Issue #2550: The approach used by client/server code for obtaining
4939 ports to listen on in network-oriented tests has been refined in an
4940 effort to facilitate running multiple instances of the entire
4941 regression test suite in parallel without issue.
4942 test_support.bind_port() has been fixed such that it will always
4943 return a unique port -- which wasn't always the case with the
4944 previous implementation, especially if socket options had been set
4945 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4946 new implementation of bind_port() will actually raise an exception
4947 if it is passed an AF_INET/SOCK_STREAM socket with either the
4948 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4949 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4950 the socket it's been passed. This currently only applies to
4951 Windows. This option prevents any other sockets from binding to the
4952 host/port we've bound to, thus removing the possibility of the
4953 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4954 when a second SOCK_STREAM socket binds and accepts to a host/port
4955 that's already been bound by another socket. The optional preferred
4956 port parameter to bind_port() has been removed. Under no
4957 circumstances should tests be hard coding ports!
4958
4959 test_support.find_unused_port() has also been introduced, which will
4960 pass a temporary socket object to bind_port() in order to obtain an
4961 unused port. The temporary socket object is then closed and
4962 deleted, and the port is returned. This method should only be used
4963 for obtaining an unused port in order to pass to an external program
4964 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4965 a parameter to a server-oriented class that doesn't give you direct
4966 access to the underlying socket used.
4967
4968 Finally, test_support.HOST has been introduced, which should be used
4969 for the host argument of any relevant socket calls (i.e. bind and
4970 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004971
4972 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004973 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004974 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4975 test_asynchat and test_socket_ssl.
4976
Georg Brandl3ee81df2008-05-17 18:14:43 +00004977 It is now possible for multiple instances of the regression test
4978 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005257- Added the future_builtins module, which contains hex() and oct().
5258 These are the PEP 3127 version of these functions, designed to be
5259 compatible with the hex() and oct() builtins from Python 3.0. They
5260 differ slightly in their output formats from the existing, unchanged
5261 Python 2.6 builtins. The expected usage of the future_builtins
5262 module is:
5263 from future_builtins import hex, oct
5264
Eric Smith7ef40bf2008-02-20 23:34:22 +00005265- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5266 exponents for exponents with absolute value < 100. Follows C99
5267 standard. This is a change on Windows, which would use 3 digits.
5268 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5269 so that any alterations it does to the resulting string will be
5270 available in stringlib/formatter.h (for float.__format__).
5271
Eric Smith5a3c1352008-02-19 13:21:56 +00005272- Implemented PEP 3101, Advanced String Formatting. This adds a new
5273 builtin format(); a format() method for str and unicode; a
5274 __format__() method to object, str, unicode, int, long, float, and
5275 datetime; the class string.Formatter; and the C API
5276 PyObject_Format().
5277
Georg Brandl3ee81df2008-05-17 18:14:43 +00005278- Fixed several potential crashes, all caused by specially crafted
5279 __del__ methods exploiting objects in temporarily inconsistent
5280 state.

5291 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005292
Georg Brandl3ee81df2008-05-17 18:14:43 +00005293- Issue #2045: Fix an infinite recursion triggered when printing a
5294 subclass of collections.defaultdict, if its default_factory is set
5295 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005296

5306
Georg Brandl3ee81df2008-05-17 18:14:43 +00005307- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5308 calls. Python expected the return type int but the fork familie
5309 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005323- Patch #1473257: generator objects gain a gi_code attribute. This is
5324 the same object as the func_code attribute of the function that
5325 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005326
Georg Brandl3ee81df2008-05-17 18:14:43 +00005327- Issue #1920: "while 0" statements were completely removed by the
5328 compiler, even in the presence of an "else" clause, which is
5329 supposed to be run when the condition is false. Now the compiler
5330 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005331

Georg Brandl3ee81df2008-05-17 18:14:43 +00005340- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005341 several extension methods and modules do not work without unicode
5342 support.
5343
Georg Brandl26543b12008-01-21 18:36:51 +00005344- Issue #1882: when compiling code from a string, encoding cookies in the
5345 second line of code were not always recognized correctly.
5346
Georg Brandl14404b62008-01-19 19:27:05 +00005347- Issue #1679: "0x" was taken as a valid integer literal.
5348
Georg Brandl6caad7d2008-01-26 14:19:22 +00005349- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005350 added.
5351
Christian Heimesc94e2b52008-01-14 04:13:37 +00005352- sys.float_info / PyFloat_GetInfo: The floating point information
5353 object was converted from a dict to a specialized structseq object.
5354
Georg Brandl3ee81df2008-05-17 18:14:43 +00005355- Patch #1816: Added sys.flags structseq. It exposes the status of
5356 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005357
Georg Brandl3ee81df2008-05-17 18:14:43 +00005358- Objects/structseq.c: Implemented new structseq representation. The
5359 patch makes structseqs (e.g. the return value of os.stat) more
5360 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005361
Georg Brandl3ee81df2008-05-17 18:14:43 +00005362- Patch #1700288: added a type attribute cache that caches method
5363 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005364
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005365- Bug #1776: __import__() no longer accepts filenames on any platform.
5366 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005367
Georg Brandlaed6c662008-01-07 17:25:53 +00005368- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5369
Georg Brandl3ee81df2008-05-17 18:14:43 +00005370- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5371 envvar and sys.dont_write_bytecode attribute. All these can be set
5372 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005373
Georg Brandl3ee81df2008-05-17 18:14:43 +00005374- Improve some exception messages when Windows fails to load an
5375 extension module. Now we get for example '%1 is not a valid Win32
5376 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005377
Georg Brandl3ee81df2008-05-17 18:14:43 +00005378- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005380- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5381 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005382
Christian Heimes0a8143f2007-12-18 23:22:54 +00005383- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005384 and INF. float("nan"), float("inf") and float("-inf") now work on
5385 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005386
Georg Brandl3ee81df2008-05-17 18:14:43 +00005387- Compiler now generates simpler and faster code for dictionary
5388 literals. The oparg for BUILD_MAP now indicates an estimated
5389 dictionary size. There is a new opcode, STORE_MAP, for adding
5390 entries to the dictionary.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00005400- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00005401 SystemError.
5402
Nick Coghlanef01d822007-12-03 12:55:17 +00005403- PEP 366: Allow explicit relative imports when executing modules
5404 inside packages with the -m switch via a new module level
5405 __package__ attribute.
5406
Georg Brandl3ee81df2008-05-17 18:14:43 +00005407- Issue #1402: Fix a crash on exit, when another thread is still
5408 running, and if the deallocation of its frames somehow calls the
5409 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00005410

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00005414 attribute of an empty cell object.
5415
Georg Brandl3ee81df2008-05-17 18:14:43 +00005416- Issue #1460: The utf-7 incremental decoder did not accept truncated
5417 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00005418
Georg Brandl3ee81df2008-05-17 18:14:43 +00005419- Patch #1739468: Directories and zipfiles containing a __main__.py
5420 file can now be directly executed by passing their name to the
5421 interpreter. The directory/zipfile is automatically inserted as the
5422 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005423
Georg Brandl3ee81df2008-05-17 18:14:43 +00005424- Issue #1265: Fix a problem with sys.settrace, if the tracing
5425 function uses a generator expression when at the same time the
5426 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005427
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005428- sets and frozensets now have an isdisjoint() method.
5429
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005430- optimize the performance of builtin.sum().
5431
Neal Norwitz44f326e2007-10-05 05:29:17 +00005432- Fix warnings found by the new version of the Coverity checker.
5433
Georg Brandl21e99f42010-03-07 15:23:59 +00005434- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005435 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5436 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005437
Georg Brandl3ee81df2008-05-17 18:14:43 +00005438- Issue #1686386: Tuple's tp_repr did not take into account the
5439 possibility of having a self-referential tuple, which is possible
5440 from C code. Nor did object's tp_str consider that a type's tp_str
5441 could do something that could lead to an inifinite recursion.
5442 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5443 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005444
Georg Brandl3ee81df2008-05-17 18:14:43 +00005445- Issue #1164: It was possible to trigger deadlock when using the
5446 'print' statement to write to a file since the GIL was not released
5447 as needed. Now PyObject_Print() does the right thing along with
5448 various tp_print implementations of the built-in types and those in
5449 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005450
Georg Brandl3ee81df2008-05-17 18:14:43 +00005451- Issue #1147: Exceptions were directly allowing string exceptions in
5452 their throw() method even though string exceptions no longer
5453 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005454
Georg Brandl3ee81df2008-05-17 18:14:43 +00005455- Issue #1096: Prevent a segfault from getting the repr of a very
5456 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005457
Brett Cannon1e534b52007-09-07 04:18:30 +00005458- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005459 PyObject_Call() never calling back out to Python code to trigger
5460 recursion depth updates/checks. Required the creation of a static
5461 RuntimeError instance in case normalizing an exception put the
5462 recursion check value past its limit. Fixes crashers
5463 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005464
Georg Brandl3ee81df2008-05-17 18:14:43 +00005465- Patch #1031213: Decode source line in SyntaxErrors back to its

5469 with %G.
5470
Georg Brandl3ee81df2008-05-17 18:14:43 +00005471- Prevent expandtabs() on string and unicode objects from causing a
5472 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00005473

Georg Brandla5ea6892007-06-01 11:33:33 +00005477
Neal Norwitz0ac60192007-05-27 04:08:54 +00005478- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005479 __*__ attributes. (Some already existed, e.g., __doc__ and
5480 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005481
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005482- Add -3 option to the interpreter to warn about features that are
5483 deprecated and will be changed/removed in Python 3.0.
5484
Georg Brandl2134e752007-05-21 20:34:16 +00005485- Patch #1686487: you can now pass any mapping after '**' in function
5486 calls.
5487
Collin Winter62903052007-05-18 23:11:24 +00005488- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005489 "except E as target:". This is to provide forwards compatibility
5490 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005491
Brett Cannon229cee22007-05-05 01:34:02 +00005492- Deprecate BaseException.message as per PEP 352.
5493
Georg Brandl3ee81df2008-05-17 18:14:43 +00005494- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005495 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005496
Vinay Sajip8549ce32007-05-06 17:53:37 +00005497- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005498 setting a plain string, ie don't expand to single letter identifiers.
5499
Raymond Hettinger13936692007-04-11 18:40:58 +00005500- Request #1191699: Slices can now be pickled.
5501
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005502- Request #1193128: str.translate() now allows a None argument for
5503 translations that only remove characters without re-mapping the
5504 remaining characters.
5505
Georg Brandl5cb76c12007-03-21 09:00:39 +00005506- Patch #1682205: a TypeError while unpacking an iterable is no longer
5507 masked by a generic one with the message "unpack non-sequence".
5508
Neal Norwitzaa754b72007-03-21 06:39:48 +00005509- Remove unused file Python/fmod.c.
5510
Guido van Rossum143b5642007-03-23 04:58:42 +00005511- Bug #1683368: The object.__init__() and object.__new__() methods are
5512 now stricter in rejecting excess arguments. The only time when
5513 either allows excess arguments is when it is not overridden and the
5514 other one is. For backwards compatibility, when both are
5515 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005516 warning later). Also, type.__init__() insists on the same signature
5517 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005518
Georg Brandl3ee81df2008-05-17 18:14:43 +00005519- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5520 object to complex using its __complex__() method before falling back
5521 to the __float__() method. Therefore, the functions in the cmath
5522 module now can operate on objects that define a __complex__()
5523 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005524
Georg Brandl3ee81df2008-05-17 18:14:43 +00005525- Patch #1623563: allow __class__ assignment for classes with
5526 __slots__. The old and the new class are still required to have the
5527 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00005528
Georg Brandl3ee81df2008-05-17 18:14:43 +00005529- Patch #1642547: Fix an error/crash when encountering syntax errors
5530 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005532- Patch #1462488: Python no longer segfaults when
5533 ``object.__reduce_ex__()`` is called with an object that is faking
5534 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005535
Georg Brandl3ee81df2008-05-17 18:14:43 +00005536- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00005539- Patch #1444529: the builtin compile() now accepts keyword arguments.
5540
Georg Brandl7b9c5552007-03-12 14:30:05 +00005541- Bug #1678647: write a newline after printing an exception in any
5542 case, even when converting the value to a string failed.
5543
Georg Brandl871f1bc2007-03-12 13:17:36 +00005544- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005545 its argument, if it exists. If not, it will work like before. This
5546 allows customizing the output of dir() in the presence of a
5547 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005548
Collin Winter276887b2007-03-12 16:11:39 +00005549- Patch #922167: Python no longer segfaults when faced with infinitely
5550 self-recursive reload() calls (as reported by bug #742342).
5551
Georg Brandl3ee81df2008-05-17 18:14:43 +00005552- Patch #1675981: remove unreachable code from ``type.__new__()``
5553 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005555- Patch #1491866: change the complex() constructor to allow
5556 parthensized forms. This means complex(repr(x)) now works instead of
5557 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005558
Georg Brandlaa2321b2007-03-07 00:40:28 +00005559- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005560 makes the filenames the warning module prints much more sensible
5561 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005562
Georg Brandl49aafc92007-03-07 00:34:46 +00005563- Variant of patch #697613: don't exit the interpreter on a SystemExit
5564 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00005565 variable is given, but break into the interactive interpreter just
5566 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005571- Bug #1674503: close the file opened by execfile() in an error
5572 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00005573
Georg Brandl0fca97a2007-03-05 22:28:08 +00005574- Patch #1674228: when assigning a slice (old-style), check for the
5575 sq_ass_slice instead of the sq_slice slot.
5576
Georg Brandl3ee81df2008-05-17 18:14:43 +00005577- When printing an unraisable error, don't print exceptions. before
5578 the name. This duplicates the behavior whening normally printing

Facundo Batistad918a652007-04-24 13:54:38 +00006070- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006071 the client's request was successfully received, understood, and
6072 accepted. Now in these cases no error is raised in urllib (issue
6073 #1177) and urllib2.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00006081- Added a timeout parameter to the constructor of other protocols
6082 (telnetlib, ftplib, smtplib and poplib). This is second part of the
6083 work started with create_connection() and timeout in httplib, and
6084 closes patch #723312.
6085
Vinay Sajip8549ce32007-05-06 17:53:37 +00006086- Patch #1676823: Added create_connection() to socket.py, which may be

Georg Brandl3ee81df2008-05-17 18:14:43 +00006112 AttributeError instead of an IOError when the server's response
6113 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00006114

Georg Brandl3ee81df2008-05-17 18:14:43 +00006119- Patch #1429539: pdb now correctly initializes the __main__ module
6120 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00006121 correctly now.

6145
Georg Brandl92a6bae2007-03-13 17:43:32 +00006146- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006147 are set for invalid interpolation sequences that would lead to
6148 errors on reading back those values.

6191 returned string up to the first NUL character.

6202
Georg Brandl3ee81df2008-05-17 18:14:43 +00006203- unittest now verifies more of its assumptions. In particular,
6204 TestCase and TestSuite subclasses (not instances) are no longer
6205 accepted in TestSuite.addTest(). This should cause no
6206 incompatibility since it never made sense with ordinary subclasses
6207 -- the failure just occurred later, with a more cumbersome
6208 exception.

6217 given a unicode argument and os.listdir() returns unicode filenames.
6218
Georg Brandl3ee81df2008-05-17 18:14:43 +00006219- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00006597 time so that opening a database previously created with the DB_DUP
6598 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6599 opens. Specifically: dictionary assignment to a DB object will
6600 replace all values for a given key when the database allows
6601 duplicate values. DB users should use DB.put(k, v) when they want
6602 to store duplicates; not DB[k] = v.

6609 characters with ASCII value less than 32. Also, it correctly quotes
6610 dots only if they occur on a single line, as opposed to the previous
6611 behavior of quoting dots if they are the second character of any
6612 line.
