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

Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000919- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
920 start byte and the continuation byte(s) are now considered invalid, instead
921 of the number of bytes specified by the start byte.
922 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
923 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
924 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
925 Previous versions returned a single u'\ufffd'.

Mark Dickinson23f0d6b2010-06-05 11:52:24 +0000927- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +0000928 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
929 arises from the "Overriding __eq__ blocks inheritance ..." warning
930 when turned into an exception: in this case the exception simply
931 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000933- Issue #8748: Fix two issues with comparisons between complex and integer
934 objects. (1) The comparison could incorrectly return True in some cases
935 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
936 (2) The comparison raised an OverflowError for large integers, leading
937 to unpredictable exceptions when combining integers and complex objects
938 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +0000940- Issue #5211: Implicit coercion for the complex type is now completely
941 removed. (Coercion for arithmetic operations was already removed in 2.7
942 alpha 4, but coercion for rich comparisons was accidentally left in.)

1185 indefinitely if the other end didn't respond.
1186
Georg Brandlfee0f442010-05-22 21:26:21 +00001187- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00001280 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

1304
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001305- Issue #7301: Add environment variable $PYTHONWARNINGS.
1306
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001307- Issue #8329: Don't return the same lists from select.select when no fds are
1308 changed.
1309
Georg Brandlfee0f442010-05-22 21:26:21 +00001310- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001311 on 64-bit machines. The shift count for either left or right shift is
1312 permitted to be up to sys.maxsize.
1313
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001314- Ensure that tokenization of identifiers is not affected by locale.

Georg Brandlfee0f442010-05-22 21:26:21 +00001320- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1321 with a non-empty format string. This is an effort to future-proof user
1322 code. If a derived class does not currently implement __format__ but later
1323 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001324 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001325 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001358- Issue #8257: The Decimal construct now accepts a float instance directly,
1359 converting that float to a Decimal of equal value:

Georg Brandlfee0f442010-05-22 21:26:21 +00001375- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1376 InvalidOperation instead of returning False. (Comparisons involving a quiet
1377 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1378 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001379
Georg Brandlfee0f442010-05-22 21:26:21 +00001380- Issue #2531: Comparison operations between floats and Decimal instances now
1381 return a result based on the numeric values of the operands; previously they
1382 returned an arbitrary result based on the relative ordering of id(float) and
1383 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00001386 argument `-` which tells it to read files to compile from stdin. Each line is
1387 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +00001397- Comparisons using one of <, <=, >, >= between a complex instance and a
1398 Fractions instance now raise TypeError instead of returning True/False. This
1399 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1400 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00001818 file position when calling `truncate()`. It would previously change the file
1819 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001820 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1821

1823 class used to represent files stored inside an archive. The new
1824 implementation is significantly faster and can be wrapped in a

1826 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

1915-----------------
1916
Georg Brandlba83f822010-03-14 09:50:54 +00001917- The ``__complex__()`` method is now looked up on the class of instances to
1918 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00001919
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001920- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,

1922
Mark Dickinson1b34d252010-01-01 17:27:30 +00001923- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001924 DeprecationWarning when passed a float argument where an integer was expected.
1925 These functions and methods now raise TypeError instead. The majority of the
1926 effects of this change are in the extension modules, but some core functions
1927 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1928 and many unicode/str methods.

1940
Georg Brandlba83f822010-03-14 09:50:54 +00001941- Issue #1811: Improve accuracy and cross-platform consistency for true division
1942 of integers: the result of a/b is now correctly rounded for ints a and b (at
1943 least on IEEE 754 platforms), and in particular does not depend on the
1944 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00001946- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the

Ronald Oussoren92919a62009-12-24 13:30:58 +00001951 executables on OSX.
1952
Georg Brandlba83f822010-03-14 09:50:54 +00001953 These executables now work properly with the arch(1) command: ``arch -ppc
1954 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00001978 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

Georg Brandlba83f822010-03-14 09:50:54 +00002118- Issue #7117: On almost all platforms: float-to-string and string-to-float
2119 conversions within Python are now correctly rounded. Places these conversions
2120 occur include: str for floats and complex numbers; the float and complex
2121 constructors; old-style and new-style numeric formatting; serialization and
2122 deserialization of floats and complex numbers using marshal, pickle and json;
2123 parsing of float and imaginary literals in Python code; Decimal-to-float
2124 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002125
Georg Brandlba83f822010-03-14 09:50:54 +00002126 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2127 providing correctly-rounded strtod and dtoa C functions. This code is
2128 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2129 the C compiler. There may be a small number of platforms on which correct
2130 operation of this code cannot be guaranteed, so the code is not used: notably,
2131 this applies to platforms where the C double format is not IEEE 754 binary64,
2132 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2133 and Python's configure script is unable to determine how to change the FPU
2134 precision. On these platforms conversions use the platform strtod and dtoa,
2135 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002137- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2138 uses the correctly-rounded string <-> float conversions described above (when
2139 available), and so produces correctly rounded results that will display nicely
2140 under the float repr. There are two related small changes: (1) round now
2141 accepts any class with an ``__index__()`` method for its second argument (but
2142 no longer accepts floats for the second argument), and (2) an excessively
2143 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2144 raises an exception.

3726 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
3727 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3728 neither __int__ nor __long__, TypeError used to be raised (with a

3733 argument with an __int__ method can be packed, but use of this feature

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003927- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

3929 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3930 ``printf`` function, whereas PyString_FromFormat has an independent
3931 implementation and uses "%zd" on all platforms for size_t values.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004096What's New in Python 2.6 beta 3?
4097================================
4098
Barry Warsaw07a4a382008-08-21 01:15:08 +00004099*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004100
4101Core and Builtins
4102-----------------
4103
Guido van Rossumf8402962008-08-20 15:01:50 +00004104- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4105 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4106 extensions do not automatically benefit from the class attribute
4107 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4108 to their tp_flags field if they care. This is a backwards
4109 compatibility feature; in 3.0, all types will use the cache by
4110 default.
4111
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004112- Keyword arguments can now follow starred arguments. (``f(a, *args,
4113 keyword=23)`` is now valid syntax.)
4114
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004115- ctypes function pointers that are COM methods have a boolean True
4116 value again.
4117
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004118- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4119 by denying s# to parse objects that have a releasebuffer procedure,
4120 and introducing s*.
4121
Georg Brandl1e13ea92008-08-11 09:07:59 +00004122- Issue #3537: Fix an assertion failure when an empty but presized dict
4123 object was stored in the freelist.
4124
Mark Dickinsonb6467572008-08-04 21:30:09 +00004125- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4126 ValueError consistently across platforms.
4127
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004128- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4129 (64bit Unix, for example), unichr() would truncate its argument and return
4130 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4131
Neal Norwitze7d8be82008-07-31 17:17:14 +00004132- Apply security patches from Apple.
4133
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004134- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4135 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4136
Antoine Pitrou92f82162008-07-25 22:22:08 +00004137- Issue #1819: function calls with several named parameters are now on
4138 average 35% faster (as measured by pybench).
4139
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004140- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4141 the python debugger steps into a class statement: the free variables (local
4142 variables defined in an outer scope) would be deleted from the outer scope.
4143
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004144- Issue #2620: Overflow checking when allocating or reallocating memory
4145 was not always being done properly in some python types and extension
4146 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4147 all been updated to perform better checks and places in the code that
4148 would previously leak memory on the error path when such an allocation
4149 failed have been fixed.

4152-------
4153
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004154- Issue #3612: Added some missing basic types in ctypes.wintypes.
4155
Benjamin Petersone977ad42008-08-20 01:42:01 +00004156- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4157 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4158
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004159- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4160 version reported by these tools does not necessarily follow the python
4161 version numbering scheme, so the module is less strict when parsing it.
4162
Nick Coghlanf70385a2008-08-18 12:42:46 +00004163- Issue #2235: Added Py3k warnings for types which will become unhashable
4164 under the stricter __hash__ inheritance rules in 3.0. Several types
4165 which did not meet the rules for hash invariants and were already
4166 unhashable in 3.0 have now been explicitly flagged as unhashable in
4167 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4168 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4169
Brett Cannon88f801d2008-08-18 00:46:22 +00004170- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4171 imported into the module but exposed as part of the module's API.
4172
Brett Cannon7b96f072008-08-18 00:41:11 +00004173- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4174
Brett Cannon46225e72008-08-18 00:36:52 +00004175- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004177- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4178
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004179- Issue #3575: Incremental decoder's decode function now takes bytearray
4180 by using 's*' instead of 't#'.
4181
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004182- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004183 fails unicode conversion on 2nd parameter. (windows only)
4184
Georg Brandl222e2082010-08-01 22:27:39 +00004185- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004186 in a redirect.
4187
Brett Cannonabe423e2008-08-16 21:47:07 +00004188- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004189 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004190
Facundo Batistaeb90b782008-08-16 14:44:07 +00004191- Issue #2776: fixed small issue when handling an URL with double slash
4192 after a 302 response in the case of not going through a proxy.
4193
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004194- Issue #2676: in the email package, content-type parsing was hanging on
4195 pathological input because of quadratic or exponential behaviour of a
4196 regular expression.
4197
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004198- Issue #3476: binary buffered reading through the new "io" library is now
4199 thread-safe.
4200
Brett Cannonbf3157b2008-08-14 05:00:03 +00004201- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4202 since mimetools itself is deprecated. Because modules are cached, all
4203 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4204
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004205- Issue #3134: shutil referenced undefined WindowsError symbol.
4206
Robert Schuppenies14646332008-08-10 11:01:53 +00004207- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4208 menu entries were not deleted.
4209
Brett Cannon83e81842008-08-09 23:30:55 +00004210- Copied the implementation of reduce() to _functools.reduce() to have a
4211 version that did not raise a DeprecationWarning under -3.
4212
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004213- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4214 a MemoryError rather than silently stop the iteration.
4215
Guido van Rossum59ce9012008-08-09 14:55:34 +00004216- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4217 to _sre.compile() will now be rejected. This should not affect anybody
4218 since the re.compile() function never generates invalid re-bytecode.
4219
Skip Montanaroa032bf42008-08-08 22:52:51 +00004220- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4221 upon first access it can be automatically initialized from the csv file if
4222 it wasn't initialized during instantiation.
4223
Brett Cannon3aa2a492008-08-06 22:28:09 +00004224- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4225 the reload() built-in has been removed.
4226
Brett Cannon7e30b672008-08-04 21:52:25 +00004227- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004228 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00004239 asking for a specific length. This problem only affected files opened
4240 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004241

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004265- Issue #3394: zipfile.writestr sets external attributes when passed a
4266 file name rather than a ZipInfo instance, so files are extracted with
4267 mode 0600 rather than 000 under Unix.
4268
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004269- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

4283
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004284- Issue #643841: The language reference now provides more detailed
4285 coverage of the lookup process for special methods. The disclaimers
4286 regarding lack of coverage of new-style classes have also been

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004290What's New in Python 2.6 beta 2?
4291================================
4292
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004293*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004295Core and Builtins
4296-----------------
4297
Georg Brandl3e483f62008-07-16 22:57:41 +00004298- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4299 its methods now allow for items objects that can be converted to
4300 an integer using operator.index().
4301
Mark Dickinson64b7e502008-07-16 09:40:03 +00004302- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4303 produced a ValueError instead of giving the correct float.
4304
Eric Smitha5fa5a22008-07-16 00:11:49 +00004305- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4306 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4307
Mark Dickinson7103aa42008-07-15 19:08:33 +00004308- Issue #3008: the float type has a new instance method 'float.hex'
4309 and a new class method 'float.fromhex' to convert floating-point
4310 numbers to and from hexadecimal strings, respectively.
4311
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004312- Issue #2235: __hash__ is once again inherited by default. To allow
4313 collections.Hashable to remain meaningful in the presence of the
4314 default hash implementation (object.__hash__), it is now possible
4315 to explicit block inheritance of hash by setting __hash__=None at
4316 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4317 level.
4318
Nick Coghlanb028f502008-07-13 14:52:36 +00004319- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4320 the parent module cannot be found while performing an absolute import.
4321 This means that an incorrectly defined __package__ attribute will
4322 now only prevent relative imports in that module rather than causing
4323 all imports from that module to fail.
4324
Nick Coghlan14ff9942008-07-08 14:21:42 +00004325- Issue #2517: Allow unicode messages in Exceptions again by correctly
4326 bypassing the instance dictionary when looking up __unicode__ on
4327 new-style classes.
4328
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004329- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4330 set to a custom object whose write() method happens to install
4331 another file in sys.stdout.
4332
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004333- Issue #3088: Corrected a race condition in classes derived from
4334 threading.local: the first member set by a thread could be saved in
4335 another thread's dictionary.
4336
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004337- Issue #3004: Minor change to slice.indices(): the start and stop
4338 arguments are now treated identically, making the behaviour easier
4339 to describe and understand. For example, slice(None, -10,
4340 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4341 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4342 10, -1).
4343
Georg Brandl278fc502008-07-19 12:46:12 +00004344- Issue #3219: Calling a function with repeated keyword arguments,
4345 f(a=2, a=23), would not cause a syntax error. This was a regression
4346 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004347
Georg Brandl278fc502008-07-19 12:46:12 +00004348- Issue #2862: Make int and float freelist management consistent with
4349 other freelists. Changes their CompactFreeList apis into
4350 ClearFreeList apis and calls them via gc.collect().

4354
Thomas Heller57adf222008-08-14 19:10:48 +00004355- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4356 api functions without holding the GIL, which could lead to a fatal
4357 error when they failed.
4358
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004359- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

4368 ForkingPickler.register() to resolve conflict with ctypes.
4369
Vinay Sajip51e65192008-07-18 09:01:10 +00004370- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004371
Thomas Heller880f5292008-07-15 19:39:38 +00004372- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4373 a valid dlerror() message.

4381
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004382- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004383
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004384- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4385 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004386 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004387 content-length. The problem had been corrected in the 2.4 branch, but never
4388 merged into trunk.
4389
Georg Brandle78fbcc2008-07-05 10:13:36 +00004390- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004403- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4404 handling is now the same as that of other special attributes like __name__).
4405
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004406- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

4863 not called by default for backwards-compatibility reasons. Setting
4864 ``warnings.showwarning()`` to an implementation that lacks support
4865 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004928- Issue #2550: The approach used by client/server code for obtaining
4929 ports to listen on in network-oriented tests has been refined in an
4930 effort to facilitate running multiple instances of the entire
4931 regression test suite in parallel without issue.
4932 test_support.bind_port() has been fixed such that it will always
4933 return a unique port -- which wasn't always the case with the
4934 previous implementation, especially if socket options had been set
4935 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4936 new implementation of bind_port() will actually raise an exception
4937 if it is passed an AF_INET/SOCK_STREAM socket with either the
4938 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4939 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4940 the socket it's been passed. This currently only applies to
4941 Windows. This option prevents any other sockets from binding to the
4942 host/port we've bound to, thus removing the possibility of the
4943 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4944 when a second SOCK_STREAM socket binds and accepts to a host/port
4945 that's already been bound by another socket. The optional preferred
4946 port parameter to bind_port() has been removed. Under no
4947 circumstances should tests be hard coding ports!
4948
4949 test_support.find_unused_port() has also been introduced, which will
4950 pass a temporary socket object to bind_port() in order to obtain an
4951 unused port. The temporary socket object is then closed and
4952 deleted, and the port is returned. This method should only be used
4953 for obtaining an unused port in order to pass to an external program
4954 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4955 a parameter to a server-oriented class that doesn't give you direct
4956 access to the underlying socket used.
4957
4958 Finally, test_support.HOST has been introduced, which should be used
4959 for the host argument of any relevant socket calls (i.e. bind and
4960 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004961
4962 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004963 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004964 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4965 test_asynchat and test_socket_ssl.
4966
Georg Brandl3ee81df2008-05-17 18:14:43 +00004967 It is now possible for multiple instances of the regression test
4968 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005247- Added the future_builtins module, which contains hex() and oct().
5248 These are the PEP 3127 version of these functions, designed to be
5249 compatible with the hex() and oct() builtins from Python 3.0. They
5250 differ slightly in their output formats from the existing, unchanged
5251 Python 2.6 builtins. The expected usage of the future_builtins
5252 module is:
5253 from future_builtins import hex, oct
5254
Eric Smith7ef40bf2008-02-20 23:34:22 +00005255- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5256 exponents for exponents with absolute value < 100. Follows C99
5257 standard. This is a change on Windows, which would use 3 digits.
5258 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5259 so that any alterations it does to the resulting string will be
5260 available in stringlib/formatter.h (for float.__format__).
5261
Eric Smith5a3c1352008-02-19 13:21:56 +00005262- Implemented PEP 3101, Advanced String Formatting. This adds a new
5263 builtin format(); a format() method for str and unicode; a
5264 __format__() method to object, str, unicode, int, long, float, and
5265 datetime; the class string.Formatter; and the C API
5266 PyObject_Format().
5267
Georg Brandl3ee81df2008-05-17 18:14:43 +00005268- Fixed several potential crashes, all caused by specially crafted
5269 __del__ methods exploiting objects in temporarily inconsistent
5270 state.

5281 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005282
Georg Brandl3ee81df2008-05-17 18:14:43 +00005283- Issue #2045: Fix an infinite recursion triggered when printing a
5284 subclass of collections.defaultdict, if its default_factory is set
5285 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005286
Christian Heimesf75dbef2008-02-08 00:11:31 +00005287- Fixed a minor memory leak in dictobject.c. The content of the free

5296
Georg Brandl3ee81df2008-05-17 18:14:43 +00005297- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5298 calls. Python expected the return type int but the fork familie
5299 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005313- Patch #1473257: generator objects gain a gi_code attribute. This is
5314 the same object as the func_code attribute of the function that
5315 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005316
Georg Brandl3ee81df2008-05-17 18:14:43 +00005317- Issue #1920: "while 0" statements were completely removed by the
5318 compiler, even in the presence of an "else" clause, which is
5319 supposed to be run when the condition is false. Now the compiler
5320 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005321

Georg Brandl3ee81df2008-05-17 18:14:43 +00005345- Patch #1816: Added sys.flags structseq. It exposes the status of
5346 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005347
Georg Brandl3ee81df2008-05-17 18:14:43 +00005348- Objects/structseq.c: Implemented new structseq representation. The
5349 patch makes structseqs (e.g. the return value of os.stat) more
5350 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005351
Georg Brandl3ee81df2008-05-17 18:14:43 +00005352- Patch #1700288: added a type attribute cache that caches method
5353 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005354
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005355- Bug #1776: __import__() no longer accepts filenames on any platform.
5356 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005357
Georg Brandlaed6c662008-01-07 17:25:53 +00005358- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5359
Georg Brandl3ee81df2008-05-17 18:14:43 +00005360- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5361 envvar and sys.dont_write_bytecode attribute. All these can be set
5362 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005363
Georg Brandl3ee81df2008-05-17 18:14:43 +00005364- Improve some exception messages when Windows fails to load an
5365 extension module. Now we get for example '%1 is not a valid Win32
5366 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005367
Georg Brandl3ee81df2008-05-17 18:14:43 +00005368- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005370- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5371 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005372
Christian Heimes0a8143f2007-12-18 23:22:54 +00005373- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005374 and INF. float("nan"), float("inf") and float("-inf") now work on
5375 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005376
Georg Brandl3ee81df2008-05-17 18:14:43 +00005377- Compiler now generates simpler and faster code for dictionary
5378 literals. The oparg for BUILD_MAP now indicates an estimated
5379 dictionary size. There is a new opcode, STORE_MAP, for adding
5380 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00005381
Georg Brandl3ee81df2008-05-17 18:14:43 +00005382- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005387- Issue #1538: Avoid copying string in split/rsplit if the split char
5388 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00005389
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00005390- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00005391 SystemError.
5392
Nick Coghlanef01d822007-12-03 12:55:17 +00005393- PEP 366: Allow explicit relative imports when executing modules
5394 inside packages with the -m switch via a new module level
5395 __package__ attribute.
5396

5398 running, and if the deallocation of its frames somehow calls the
5399 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00005400

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00005404 attribute of an empty cell object.
5405
Georg Brandl3ee81df2008-05-17 18:14:43 +00005406- Issue #1460: The utf-7 incremental decoder did not accept truncated
5407 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00005408
Georg Brandl3ee81df2008-05-17 18:14:43 +00005409- Patch #1739468: Directories and zipfiles containing a __main__.py
5410 file can now be directly executed by passing their name to the
5411 interpreter. The directory/zipfile is automatically inserted as the
5412 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005413
Georg Brandl3ee81df2008-05-17 18:14:43 +00005414- Issue #1265: Fix a problem with sys.settrace, if the tracing
5415 function uses a generator expression when at the same time the
5416 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005417
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005418- sets and frozensets now have an isdisjoint() method.
5419
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005420- optimize the performance of builtin.sum().
5421
Neal Norwitz44f326e2007-10-05 05:29:17 +00005422- Fix warnings found by the new version of the Coverity checker.
5423
Georg Brandl21e99f42010-03-07 15:23:59 +00005424- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005425 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5426 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005427
Georg Brandl3ee81df2008-05-17 18:14:43 +00005428- Issue #1686386: Tuple's tp_repr did not take into account the
5429 possibility of having a self-referential tuple, which is possible
5430 from C code. Nor did object's tp_str consider that a type's tp_str
5431 could do something that could lead to an inifinite recursion.
5432 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5433 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005434
Georg Brandl3ee81df2008-05-17 18:14:43 +00005435- Issue #1164: It was possible to trigger deadlock when using the
5436 'print' statement to write to a file since the GIL was not released
5437 as needed. Now PyObject_Print() does the right thing along with
5438 various tp_print implementations of the built-in types and those in
5439 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005440
Georg Brandl3ee81df2008-05-17 18:14:43 +00005441- Issue #1147: Exceptions were directly allowing string exceptions in
5442 their throw() method even though string exceptions no longer
5443 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005444
Georg Brandl3ee81df2008-05-17 18:14:43 +00005445- Issue #1096: Prevent a segfault from getting the repr of a very
5446 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005447
Brett Cannon1e534b52007-09-07 04:18:30 +00005448- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005449 PyObject_Call() never calling back out to Python code to trigger
5450 recursion depth updates/checks. Required the creation of a static
5451 RuntimeError instance in case normalizing an exception put the
5452 recursion check value past its limit. Fixes crashers
5453 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005454
Georg Brandl3ee81df2008-05-17 18:14:43 +00005455- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00005468- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005469 __*__ attributes. (Some already existed, e.g., __doc__ and
5470 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005471
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005472- Add -3 option to the interpreter to warn about features that are
5473 deprecated and will be changed/removed in Python 3.0.
5474
Georg Brandl2134e752007-05-21 20:34:16 +00005475- Patch #1686487: you can now pass any mapping after '**' in function
5476 calls.
5477
Collin Winter62903052007-05-18 23:11:24 +00005478- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005479 "except E as target:". This is to provide forwards compatibility
5480 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005481
Brett Cannon229cee22007-05-05 01:34:02 +00005482- Deprecate BaseException.message as per PEP 352.
5483
Georg Brandl3ee81df2008-05-17 18:14:43 +00005484- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005485 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005486
Vinay Sajip8549ce32007-05-06 17:53:37 +00005487- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005488 setting a plain string, ie don't expand to single letter identifiers.
5489
Raymond Hettinger13936692007-04-11 18:40:58 +00005490- Request #1191699: Slices can now be pickled.
5491
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005492- Request #1193128: str.translate() now allows a None argument for
5493 translations that only remove characters without re-mapping the
5494 remaining characters.
5495
Georg Brandl5cb76c12007-03-21 09:00:39 +00005496- Patch #1682205: a TypeError while unpacking an iterable is no longer
5497 masked by a generic one with the message "unpack non-sequence".
5498
Neal Norwitzaa754b72007-03-21 06:39:48 +00005499- Remove unused file Python/fmod.c.
5500
Guido van Rossum143b5642007-03-23 04:58:42 +00005501- Bug #1683368: The object.__init__() and object.__new__() methods are
5502 now stricter in rejecting excess arguments. The only time when
5503 either allows excess arguments is when it is not overridden and the
5504 other one is. For backwards compatibility, when both are
5505 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005506 warning later). Also, type.__init__() insists on the same signature
5507 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005508
Georg Brandl3ee81df2008-05-17 18:14:43 +00005509- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5510 object to complex using its __complex__() method before falling back
5511 to the __float__() method. Therefore, the functions in the cmath
5512 module now can operate on objects that define a __complex__()
5513 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005514
Georg Brandl3ee81df2008-05-17 18:14:43 +00005515- Patch #1623563: allow __class__ assignment for classes with
5516 __slots__. The old and the new class are still required to have the
5517 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00005518
Georg Brandl3ee81df2008-05-17 18:14:43 +00005519- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00005522- Patch #1462488: Python no longer segfaults when
5523 ``object.__reduce_ex__()`` is called with an object that is faking
5524 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005525
Georg Brandl3ee81df2008-05-17 18:14:43 +00005526- Patch #1680015: Don't modify __slots__ tuple if it contains an

5530
Georg Brandl7b9c5552007-03-12 14:30:05 +00005531- Bug #1678647: write a newline after printing an exception in any
5532 case, even when converting the value to a string failed.
5533
Georg Brandl871f1bc2007-03-12 13:17:36 +00005534- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005535 its argument, if it exists. If not, it will work like before. This
5536 allows customizing the output of dir() in the presence of a
5537 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00005539- Patch #922167: Python no longer segfaults when faced with infinitely
5540 self-recursive reload() calls (as reported by bug #742342).
5541
Georg Brandl3ee81df2008-05-17 18:14:43 +00005542- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00005545- Patch #1491866: change the complex() constructor to allow
5546 parthensized forms. This means complex(repr(x)) now works instead of
5547 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005548
Georg Brandlaa2321b2007-03-07 00:40:28 +00005549- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005550 makes the filenames the warning module prints much more sensible
5551 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005552
Georg Brandl49aafc92007-03-07 00:34:46 +00005553- Variant of patch #697613: don't exit the interpreter on a SystemExit
5554 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00005555 variable is given, but break into the interactive interpreter just
5556 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00005563
Georg Brandl0fca97a2007-03-05 22:28:08 +00005564- Patch #1674228: when assigning a slice (old-style), check for the
5565 sq_ass_slice instead of the sq_slice slot.
5566
Georg Brandl3ee81df2008-05-17 18:14:43 +00005567- When printing an unraisable error, don't print exceptions. before
5568 the name. This duplicates the behavior whening normally printing
5569 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00005570

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00006071- Added a timeout parameter to the constructor of other protocols
6072 (telnetlib, ftplib, smtplib and poplib). This is second part of the
6073 work started with create_connection() and timeout in httplib, and
6074 closes patch #723312.
6075
Vinay Sajip8549ce32007-05-06 17:53:37 +00006076- Patch #1676823: Added create_connection() to socket.py, which may be
6077 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00006078 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00006079

Georg Brandl3ee81df2008-05-17 18:14:43 +00006102 AttributeError instead of an IOError when the server's response
6103 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00006104

Georg Brandl3ee81df2008-05-17 18:14:43 +00006109- Patch #1429539: pdb now correctly initializes the __main__ module
6110 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00006111 correctly now.
6112

6119
Georg Brandl3ee81df2008-05-17 18:14:43 +00006120- Patch #1530482: add pydoc.render_doc() which returns the

6130 parameter which can be set to False to prevent the default
6131 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00006132
Georg Brandl9e6b4702007-03-13 18:15:41 +00006133- Patch #1581073: add a flag to textwrap that prevents the dropping of
6134 whitespace while wrapping.
6135
Georg Brandl92a6bae2007-03-13 17:43:32 +00006136- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006137 are set for invalid interpolation sequences that would lead to
6138 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00006139

6181 returned string up to the first NUL character.

6192
Georg Brandl3ee81df2008-05-17 18:14:43 +00006193- unittest now verifies more of its assumptions. In particular,
6194 TestCase and TestSuite subclasses (not instances) are no longer
6195 accepted in TestSuite.addTest(). This should cause no
6196 incompatibility since it never made sense with ordinary subclasses
6197 -- the failure just occurred later, with a more cumbersome
6198 exception.

6208
Georg Brandl3ee81df2008-05-17 18:14:43 +00006209- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00006587 time so that opening a database previously created with the DB_DUP
6588 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6589 opens. Specifically: dictionary assignment to a DB object will
6590 replace all values for a given key when the database allows
6591 duplicate values. DB users should use DB.put(k, v) when they want
6592 to store duplicates; not DB[k] = v.

6599 characters with ASCII value less than 32. Also, it correctly quotes
6600 dots only if they occur on a single line, as opposed to the previous
6601 behavior of quoting dots if they are the second character of any
6602 line.
