510 by Andrew Bennetts.

Raymond Hettinger20397532010-09-12 02:11:45 +0000520- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
521 This prevents user-created self-referencing ordered dictionaries from
522 becoming permanently uncollectable GC garbage. The downside is that
523 removing __del__ means that the internal doubly-linked list has to wait for
524 GC collection rather than freeing memory immediately when the refcnt drops
525 to zero.
526
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000527- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

530
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000531- Issue #9792: In case of connection failure, socket.create_connection()
532 would swallow the exception and raise a new one, making it impossible
533 to fetch the original errno, or to filter timeout errors. Now the
534 original error is re-raised.
535
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000536- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
537 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
538 be updated back after the system call. Original patch by Brian Brazil.
539
Antoine Pitroudca9de92010-09-04 17:52:26 +0000540- Issue #1100562: Fix deep-copying of objects derived from the list and

544 ConfigParser.write.
545
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000546- Issue #808164: Fixed socket.close to avoid references to globals, to
547 avoid issues when socket.close is called from a __del__ method.
548
Terry Reedyd2d2ae92010-11-11 23:22:19 +0000549- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which

555
R. David Murray7c4bf552010-08-25 01:45:57 +0000556- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
557 character years even if the message contains RFC822 two character years.
558
Daniel Stutzbach91287322010-08-24 21:09:30 +0000559- Issue #8750: Fixed MutableSet's methods to correctly handle

561

575
Benjamin Peterson52c36052010-08-21 03:03:22 +0000576- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
577 are not held onto after they are deleted elsewhere.
578
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000579- Issue #9626: the view methods for collections.OrderedDict() were returning
580 the unordered versions inherited from dict. Those methods are now
581 overridden to provide ordered views.
582
Éric Araujo0389ae62010-08-14 03:07:46 +0000583- Issue #8688: MANIFEST files created by distutils now include a magic
584 comment indicating they are generated. Manually maintained MANIFESTs

586
Antoine Pitroue1436d12010-08-12 15:25:51 +0000587- Issue #7467: when reading a file from a ZIP archive, its CRC is checked

Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000983- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
984 start byte and the continuation byte(s) are now considered invalid, instead
985 of the number of bytes specified by the start byte.
986 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
987 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
988 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
989 Previous versions returned a single u'\ufffd'.

993 arises from the "Overriding __eq__ blocks inheritance ..." warning
994 when turned into an exception: in this case the exception simply
995 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000997- Issue #8748: Fix two issues with comparisons between complex and integer
998 objects. (1) The comparison could incorrectly return True in some cases
999 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1000 (2) The comparison raised an OverflowError for large integers, leading
1001 to unpredictable exceptions when combining integers and complex objects
1002 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00001004- Issue #5211: Implicit coercion for the complex type is now completely
1005 removed. (Coercion for arithmetic operations was already removed in 2.7
1006 alpha 4, but coercion for rich comparisons was accidentally left in.)
1007
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00001008- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

1196 operation raises multiple signals and more than one of those signals is
1197 trapped, the specification determines the order in which the signals should be

1385 with a non-empty format string. This is an effort to future-proof user
1386 code. If a derived class does not currently implement __format__ but later
1387 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001388 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001389 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001422- Issue #8257: The Decimal construct now accepts a float instance directly,
1423 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001424
1425 >>> Decimal(1.1)
1426 Decimal('1.100000000000000088817841970012523233890533447265625')
1427

1440 InvalidOperation instead of returning False. (Comparisons involving a quiet
1441 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1442 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00001444- Issue #2531: Comparison operations between floats and Decimal instances now
1445 return a result based on the numeric values of the operands; previously they
1446 returned an arbitrary result based on the relative ordering of id(float) and
1447 id(Decimal).

1451 read on demand and the named file is compiled immediately. (Original patch by
1452 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00001461- Comparisons using one of <, <=, >, >= between a complex instance and a
1462 Fractions instance now raise TypeError instead of returning True/False. This
1463 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1464 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00001568- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1569 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the

Georg Brandlfee0f442010-05-22 21:26:21 +00001571 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1572 inconsistent: __int__ was used for some integer codes but not for others, and
1573 the set of integer codes for which it was used differed between native packing
1574 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00001886- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1887 class used to represent files stored inside an archive. The new
1888 implementation is significantly faster and can be wrapped in a
1889 ``io.BufferedReader`` object for more speedups. It also solves an issue
1890 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00002154- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
2155 when called with invalid values.

Georg Brandlba83f822010-03-14 09:50:54 +00002157- Issue #3382: 'F' formatting for float and complex now convert the result to
2158 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
2159 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002160
Georg Brandlba83f822010-03-14 09:50:54 +00002161- Remove switch from "%f" formatting to "%g" formatting for floats larger than
2162 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00002163
Georg Brandlba83f822010-03-14 09:50:54 +00002164- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
2165 1e-100 used to raise OverflowError, but now gives the requested 120
2166 significant digits instead.

2173 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00002174
Georg Brandlba83f822010-03-14 09:50:54 +00002175- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2176 decimal string that's guaranteed to round back to x under correct rounding
2177 (with round-half-to-even rounding mode). Previously it gave a string based on
2178 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2179 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2180 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002181
Georg Brandlba83f822010-03-14 09:50:54 +00002182- Issue #7117: On almost all platforms: float-to-string and string-to-float
2183 conversions within Python are now correctly rounded. Places these conversions
2184 occur include: str for floats and complex numbers; the float and complex
2185 constructors; old-style and new-style numeric formatting; serialization and
2186 deserialization of floats and complex numbers using marshal, pickle and json;
2187 parsing of float and imaginary literals in Python code; Decimal-to-float
2188 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002189
Georg Brandlba83f822010-03-14 09:50:54 +00002190 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2191 providing correctly-rounded strtod and dtoa C functions. This code is
2192 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2193 the C compiler. There may be a small number of platforms on which correct
2194 operation of this code cannot be guaranteed, so the code is not used: notably,
2195 this applies to platforms where the C double format is not IEEE 754 binary64,
2196 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2197 and Python's configure script is unable to determine how to change the FPU
2198 precision. On these platforms conversions use the platform strtod and dtoa,
2199 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002200
Georg Brandlba83f822010-03-14 09:50:54 +00002201- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2202 uses the correctly-rounded string <-> float conversions described above (when
2203 available), and so produces correctly rounded results that will display nicely
2204 under the float repr. There are two related small changes: (1) round now
2205 accepts any class with an ``__index__()`` method for its second argument (but
2206 no longer accepts floats for the second argument), and (2) an excessively
2207 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2208 raises an exception.

2211
Georg Brandlba83f822010-03-14 09:50:54 +00002212- Fix several issues with ``compile()``. The input can now contain Windows and

2359 This more closely matches ``str()``, and reduces surprises when adding
2360 alignment flags to the empty presentation type. This also affects the new
2361 complex.__format__ in the same way.

2592 eventual KeyError would always report the empty ``frozenset()`` as the missing

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003989- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3990
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003991- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3992 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3993 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3994 ``printf`` function, whereas PyString_FromFormat has an independent
3995 implementation and uses "%zd" on all platforms for size_t values.
3996 This makes a difference on win64, where ``printf`` needs "%Id" to display
3997 64bit values.
3998
Benjamin Peterson97179b02008-09-09 20:55:01 +00003999- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
4000 error.
4001
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00004002- Issue #3777: long() applied to a float object now always return a long
4003 object; previously an int would be returned for small values. the __long__
4004 method is allowed to return either an int or a long, but the behaviour of
4005 float objects should not change to respect backward compatibility.
4006
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004007- Issue #3751: str.rpartition would perform a left-partition when called with
4008 a unicode argument.
4009
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00004010- Issue #3683: Fix compilation when --without-threads is given.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004012- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00004013 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004014 was correctly parsed but parsing of subsequent arguments failed.
4015
Vinay Sajip35e3b032008-09-01 14:33:59 +00004016- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004017 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4018 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4019 when given a tuple of classes as second argument, were looking up
4020 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4021 type object.
4022
Neal Norwitz18aa3882008-08-24 05:04:52 +00004023- Fix crashes on memory allocation failure found with failmalloc.
4024
4025- Fix memory leaks found with valgrind and update suppressions file.

4029- Fix problem using wrong name in decimal module reported by pychecker.
4030
Christian Heimes7d4c3172008-08-22 19:47:25 +00004031- Silenced another compiler warning about a used but not defined
4032 function 'stringlib_contains_obj'.
4033
Benjamin Peterson712ee922008-08-24 18:10:20 +00004034- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
4035 ``__delslice__``.

4038 library targets in the Makefile.
4039
Gregory P. Smith980b99b2008-09-07 05:15:18 +00004040- Issue #1204: The configure script now tests for additional libraries
4041 that may be required when linking against readline. This fixes issues
4042 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Brett Cannon1eaf0742008-09-02 01:25:16 +00004092 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4093 for catch_warnings() also led to an improvement in the raising of a
4094 DeprecationWarning related to warnings.warn_explicit().
4095
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004096- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004160What's New in Python 2.6 beta 3?
4161================================
4162
Barry Warsaw07a4a382008-08-21 01:15:08 +00004163*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004164
4165Core and Builtins
4166-----------------
4167
Guido van Rossumf8402962008-08-20 15:01:50 +00004168- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4169 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4170 extensions do not automatically benefit from the class attribute
4171 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4172 to their tp_flags field if they care. This is a backwards
4173 compatibility feature; in 3.0, all types will use the cache by
4174 default.
4175
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004176- Keyword arguments can now follow starred arguments. (``f(a, *args,
4177 keyword=23)`` is now valid syntax.)
4178
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004179- ctypes function pointers that are COM methods have a boolean True
4180 value again.
4181
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004182- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4183 by denying s# to parse objects that have a releasebuffer procedure,
4184 and introducing s*.
4185
Georg Brandl1e13ea92008-08-11 09:07:59 +00004186- Issue #3537: Fix an assertion failure when an empty but presized dict
4187 object was stored in the freelist.
4188
Mark Dickinsonb6467572008-08-04 21:30:09 +00004189- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4190 ValueError consistently across platforms.
4191
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004192- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4193 (64bit Unix, for example), unichr() would truncate its argument and return
4194 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4195
Neal Norwitze7d8be82008-07-31 17:17:14 +00004196- Apply security patches from Apple.
4197
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004198- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4199 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4200
Antoine Pitrou92f82162008-07-25 22:22:08 +00004201- Issue #1819: function calls with several named parameters are now on
4202 average 35% faster (as measured by pybench).
4203
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004204- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4205 the python debugger steps into a class statement: the free variables (local
4206 variables defined in an outer scope) would be deleted from the outer scope.
4207
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004208- Issue #2620: Overflow checking when allocating or reallocating memory
4209 was not always being done properly in some python types and extension
4210 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4211 all been updated to perform better checks and places in the code that
4212 would previously leak memory on the error path when such an allocation
4213 failed have been fixed.

4222
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004223- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4224 version reported by these tools does not necessarily follow the python
4225 version numbering scheme, so the module is less strict when parsing it.
4226
Nick Coghlanf70385a2008-08-18 12:42:46 +00004227- Issue #2235: Added Py3k warnings for types which will become unhashable
4228 under the stricter __hash__ inheritance rules in 3.0. Several types
4229 which did not meet the rules for hash invariants and were already
4230 unhashable in 3.0 have now been explicitly flagged as unhashable in
4231 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4232 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4233
Brett Cannon88f801d2008-08-18 00:46:22 +00004234- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

4242
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004243- Issue #3575: Incremental decoder's decode function now takes bytearray
4244 by using 's*' instead of 't#'.
4245
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004246- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004247 fails unicode conversion on 2nd parameter. (windows only)
4248
Georg Brandl222e2082010-08-01 22:27:39 +00004249- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004250 in a redirect.

Brett Cannon721b1452008-08-16 22:00:27 +00004253 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004254
Facundo Batistaeb90b782008-08-16 14:44:07 +00004255- Issue #2776: fixed small issue when handling an URL with double slash
4256 after a 302 response in the case of not going through a proxy.
4257
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004258- Issue #2676: in the email package, content-type parsing was hanging on
4259 pathological input because of quadratic or exponential behaviour of a
4260 regular expression.
4261
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004262- Issue #3476: binary buffered reading through the new "io" library is now

Brett Cannonbf3157b2008-08-14 05:00:03 +00004265- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4266 since mimetools itself is deprecated. Because modules are cached, all
4267 subsequent imports of rfc822 will not raise a visible DeprecationWarning.

Antoine Pitroude781a42008-08-09 12:43:23 +00004303 asking for a specific length. This problem only affected files opened
4304 using the new "io" module, not the built-in open() function.

4346 interaction with the tp_hash slot (added in 2.6b2) are now documented
4347
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004348- Issue #643841: The language reference now provides more detailed
4349 coverage of the lookup process for special methods. The disclaimers
4350 regarding lack of coverage of new-style classes have also been

4360-----------------
4361
Georg Brandl3e483f62008-07-16 22:57:41 +00004362- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4363 its methods now allow for items objects that can be converted to
4364 an integer using operator.index().
4365
Mark Dickinson64b7e502008-07-16 09:40:03 +00004366- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4367 produced a ValueError instead of giving the correct float.
4368
Eric Smitha5fa5a22008-07-16 00:11:49 +00004369- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4370 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4371
Mark Dickinson7103aa42008-07-15 19:08:33 +00004372- Issue #3008: the float type has a new instance method 'float.hex'
4373 and a new class method 'float.fromhex' to convert floating-point
4374 numbers to and from hexadecimal strings, respectively.
4375
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004376- Issue #2235: __hash__ is once again inherited by default. To allow
4377 collections.Hashable to remain meaningful in the presence of the
4378 default hash implementation (object.__hash__), it is now possible
4379 to explicit block inheritance of hash by setting __hash__=None at
4380 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4381 level.
4382
Nick Coghlanb028f502008-07-13 14:52:36 +00004383- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4384 the parent module cannot be found while performing an absolute import.
4385 This means that an incorrectly defined __package__ attribute will
4386 now only prevent relative imports in that module rather than causing
4387 all imports from that module to fail.
4388
Nick Coghlan14ff9942008-07-08 14:21:42 +00004389- Issue #2517: Allow unicode messages in Exceptions again by correctly
4390 bypassing the instance dictionary when looking up __unicode__ on
4391 new-style classes.

4394 set to a custom object whose write() method happens to install
4395 another file in sys.stdout.

Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004397- Issue #3088: Corrected a race condition in classes derived from
4398 threading.local: the first member set by a thread could be saved in
4399 another thread's dictionary.
4400
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004401- Issue #3004: Minor change to slice.indices(): the start and stop
4402 arguments are now treated identically, making the behaviour easier
4403 to describe and understand. For example, slice(None, -10,
4404 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4405 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4406 10, -1).
4407
Georg Brandl278fc502008-07-19 12:46:12 +00004408- Issue #3219: Calling a function with repeated keyword arguments,
4409 f(a=2, a=23), would not cause a syntax error. This was a regression
4410 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004411
Georg Brandl278fc502008-07-19 12:46:12 +00004412- Issue #2862: Make int and float freelist management consistent with
4413 other freelists. Changes their CompactFreeList apis into
4414 ClearFreeList apis and calls them via gc.collect().

4420 api functions without holding the GIL, which could lead to a fatal
4421 error when they failed.
4422
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004423- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004448- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4449 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004450 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004451 content-length. The problem had been corrected in the 2.4 branch, but never
4452 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004467- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

4469
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004470- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Benjamin Peterson23681932008-05-12 21:42:13 +00004837
Vinay Sajip9828b7e2008-06-17 11:04:02 +00004838- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004839 environment to control the '-arch' flags that are used to build
4840 an extension. This was added for compatibility with Apple's build
4841 of Python.
4842
4843- The bundled OSX-specific copy of libbffi is now in sync with the version
4844 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
4845
Georg Brandl25c34082008-08-18 23:09:49 +00004846- The threading module gained aliases for names that will be removed in the

4855
Brett Cannonb61d8012008-05-11 23:39:04 +00004856- ``Lib/lib-old`` is now added to sys.path.
4857
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004858- On MacOS X it is now possible to install the framework in 64-bit
4859 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004860 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004861
4862 This is controlled by the configure argument ``--with-universal-archs``:
4863
4864 - ``--with-universal-archs=all``: install 4-way universal
4865
4866 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4867
4868 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4869
4870 This option should be used in combination with ``--enable-universalsdk=``.
4871
4872 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00004922- Issue #1631171: Re-implement the 'warnings' module in C (the
4923 original Python code has been kept as backup). This will allow for
4924 using the 'warning's machinery in such places as the parser where
4925 use of pure Python code is not possible. Both the ``showarning()``
4926 and ``formatwarning()`` gain an optional 'line' argument which is
4927 not called by default for backwards-compatibility reasons. Setting
4928 ``warnings.showwarning()`` to an implementation that lacks support
4929 for the ``line`` argument will raise a DeprecationWarning.

4953
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004954- The getpass module has been improved on Unix. It now uses /dev/tty
4955 by default and uses stderr instead of stdout. A GetPassWarning is
4956 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00004957

Georg Brandl3ee81df2008-05-17 18:14:43 +00004971- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004972 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004992- Issue #2550: The approach used by client/server code for obtaining
4993 ports to listen on in network-oriented tests has been refined in an
4994 effort to facilitate running multiple instances of the entire
4995 regression test suite in parallel without issue.
4996 test_support.bind_port() has been fixed such that it will always
4997 return a unique port -- which wasn't always the case with the
4998 previous implementation, especially if socket options had been set
4999 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5000 new implementation of bind_port() will actually raise an exception
5001 if it is passed an AF_INET/SOCK_STREAM socket with either the
5002 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5003 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5004 the socket it's been passed. This currently only applies to
5005 Windows. This option prevents any other sockets from binding to the
5006 host/port we've bound to, thus removing the possibility of the
5007 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5008 when a second SOCK_STREAM socket binds and accepts to a host/port
5009 that's already been bound by another socket. The optional preferred
5010 port parameter to bind_port() has been removed. Under no
5011 circumstances should tests be hard coding ports!
5012
5013 test_support.find_unused_port() has also been introduced, which will
5014 pass a temporary socket object to bind_port() in order to obtain an
5015 unused port. The temporary socket object is then closed and
5016 deleted, and the port is returned. This method should only be used
5017 for obtaining an unused port in order to pass to an external program
5018 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5019 a parameter to a server-oriented class that doesn't give you direct
5020 access to the underlying socket used.
5021
5022 Finally, test_support.HOST has been introduced, which should be used
5023 for the host argument of any relevant socket calls (i.e. bind and
5024 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005025
5026 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005027 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005028 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5029 test_asynchat and test_socket_ssl.
5030
Georg Brandl3ee81df2008-05-17 18:14:43 +00005031 It is now possible for multiple instances of the regression test
5032 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005311- Added the future_builtins module, which contains hex() and oct().
5312 These are the PEP 3127 version of these functions, designed to be
5313 compatible with the hex() and oct() builtins from Python 3.0. They
5314 differ slightly in their output formats from the existing, unchanged
5315 Python 2.6 builtins. The expected usage of the future_builtins
5316 module is:
5317 from future_builtins import hex, oct
5318
Eric Smith7ef40bf2008-02-20 23:34:22 +00005319- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5320 exponents for exponents with absolute value < 100. Follows C99
5321 standard. This is a change on Windows, which would use 3 digits.
5322 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5323 so that any alterations it does to the resulting string will be
5324 available in stringlib/formatter.h (for float.__format__).
5325
Eric Smith5a3c1352008-02-19 13:21:56 +00005326- Implemented PEP 3101, Advanced String Formatting. This adds a new
5327 builtin format(); a format() method for str and unicode; a
5328 __format__() method to object, str, unicode, int, long, float, and
5329 datetime; the class string.Formatter; and the C API
5330 PyObject_Format().
5331
Georg Brandl3ee81df2008-05-17 18:14:43 +00005332- Fixed several potential crashes, all caused by specially crafted
5333 __del__ methods exploiting objects in temporarily inconsistent
5334 state.

5338 a slot on a registered virtual subclass.

5344 in order to allow pymalloc to free more arenas. Python may give back
5345 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005346
Georg Brandl3ee81df2008-05-17 18:14:43 +00005347- Issue #2045: Fix an infinite recursion triggered when printing a
5348 subclass of collections.defaultdict, if its default_factory is set
5349 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005350
Christian Heimesf75dbef2008-02-08 00:11:31 +00005351- Fixed a minor memory leak in dictobject.c. The content of the free
5352 list was not freed on interpreter shutdown.

Georg Brandl21e99f42010-03-07 15:23:59 +00005354- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005355 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005356
Georg Brandl3ee81df2008-05-17 18:14:43 +00005357- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5358 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005359 to compact the internal free lists of pre-allocted ints and floats.
5360
Georg Brandl3ee81df2008-05-17 18:14:43 +00005361- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5362 calls. Python expected the return type int but the fork familie
5363 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005364
Georg Brandl3ee81df2008-05-17 18:14:43 +00005365- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5366 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005367
Georg Brandl3ee81df2008-05-17 18:14:43 +00005368- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5369 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005370
Georg Brandl3ee81df2008-05-17 18:14:43 +00005371- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
5372 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00005374- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5375 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005376
Georg Brandl3ee81df2008-05-17 18:14:43 +00005377- Patch #1473257: generator objects gain a gi_code attribute. This is
5378 the same object as the func_code attribute of the function that
5379 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005380
Georg Brandl3ee81df2008-05-17 18:14:43 +00005381- Issue #1920: "while 0" statements were completely removed by the
5382 compiler, even in the presence of an "else" clause, which is
5383 supposed to be run when the condition is false. Now the compiler
5384 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005385
Guido van Rossumeead05f2008-01-24 18:21:02 +00005386- A few crashers fixed: weakref_in_del.py (issue #1377858);
5387 loosing_dict_ref.py (issue #1303614, test67.py);
5388 borrowed_ref_[34].py (not in tracker).
5389
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005390- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005391 suppressed while an extension is loaded by calling SetErrorMode in
5392 dynload_win.c. The error is still reported properly.
5393
Georg Brandl3ee81df2008-05-17 18:14:43 +00005394- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005395 several extension methods and modules do not work without unicode
5396 support.
5397
Georg Brandl26543b12008-01-21 18:36:51 +00005398- Issue #1882: when compiling code from a string, encoding cookies in the
5399 second line of code were not always recognized correctly.
5400
Georg Brandl14404b62008-01-19 19:27:05 +00005401- Issue #1679: "0x" was taken as a valid integer literal.
5402
Georg Brandl6caad7d2008-01-26 14:19:22 +00005403- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005404 added.
5405
Christian Heimesc94e2b52008-01-14 04:13:37 +00005406- sys.float_info / PyFloat_GetInfo: The floating point information
5407 object was converted from a dict to a specialized structseq object.
5408
Georg Brandl3ee81df2008-05-17 18:14:43 +00005409- Patch #1816: Added sys.flags structseq. It exposes the status of
5410 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005411
Georg Brandl3ee81df2008-05-17 18:14:43 +00005412- Objects/structseq.c: Implemented new structseq representation. The
5413 patch makes structseqs (e.g. the return value of os.stat) more
5414 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005415
Georg Brandl3ee81df2008-05-17 18:14:43 +00005416- Patch #1700288: added a type attribute cache that caches method
5417 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005418
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005419- Bug #1776: __import__() no longer accepts filenames on any platform.
5420 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005421
Georg Brandlaed6c662008-01-07 17:25:53 +00005422- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5423
Georg Brandl3ee81df2008-05-17 18:14:43 +00005424- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5425 envvar and sys.dont_write_bytecode attribute. All these can be set
5426 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005427
Georg Brandl3ee81df2008-05-17 18:14:43 +00005428- Improve some exception messages when Windows fails to load an
5429 extension module. Now we get for example '%1 is not a valid Win32
5430 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005431
Georg Brandl3ee81df2008-05-17 18:14:43 +00005432- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005434- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5435 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005436
Christian Heimes0a8143f2007-12-18 23:22:54 +00005437- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005438 and INF. float("nan"), float("inf") and float("-inf") now work on
5439 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005440
Georg Brandl3ee81df2008-05-17 18:14:43 +00005441- Compiler now generates simpler and faster code for dictionary
5442 literals. The oparg for BUILD_MAP now indicates an estimated
5443 dictionary size. There is a new opcode, STORE_MAP, for adding
5444 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00005445
Georg Brandl3ee81df2008-05-17 18:14:43 +00005446- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00005454- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00005455 SystemError.
5456
Nick Coghlanef01d822007-12-03 12:55:17 +00005457- PEP 366: Allow explicit relative imports when executing modules
5458 inside packages with the -m switch via a new module level

Georg Brandl3ee81df2008-05-17 18:14:43 +00005473- Patch #1739468: Directories and zipfiles containing a __main__.py
5474 file can now be directly executed by passing their name to the
5475 interpreter. The directory/zipfile is automatically inserted as the
5476 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005477
Georg Brandl3ee81df2008-05-17 18:14:43 +00005478- Issue #1265: Fix a problem with sys.settrace, if the tracing
5479 function uses a generator expression when at the same time the
5480 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005481
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005482- sets and frozensets now have an isdisjoint() method.
5483
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005484- optimize the performance of builtin.sum().
5485
Neal Norwitz44f326e2007-10-05 05:29:17 +00005486- Fix warnings found by the new version of the Coverity checker.
5487
Georg Brandl21e99f42010-03-07 15:23:59 +00005488- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005489 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5490 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005491
Georg Brandl3ee81df2008-05-17 18:14:43 +00005492- Issue #1686386: Tuple's tp_repr did not take into account the
5493 possibility of having a self-referential tuple, which is possible
5494 from C code. Nor did object's tp_str consider that a type's tp_str
5495 could do something that could lead to an inifinite recursion.
5496 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5497 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005498
Georg Brandl3ee81df2008-05-17 18:14:43 +00005499- Issue #1164: It was possible to trigger deadlock when using the
5500 'print' statement to write to a file since the GIL was not released
5501 as needed. Now PyObject_Print() does the right thing along with
5502 various tp_print implementations of the built-in types and those in
5503 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005504
Georg Brandl3ee81df2008-05-17 18:14:43 +00005505- Issue #1147: Exceptions were directly allowing string exceptions in
5506 their throw() method even though string exceptions no longer
5507 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005508
Georg Brandl3ee81df2008-05-17 18:14:43 +00005509- Issue #1096: Prevent a segfault from getting the repr of a very
5510 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005511
Brett Cannon1e534b52007-09-07 04:18:30 +00005512- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005513 PyObject_Call() never calling back out to Python code to trigger
5514 recursion depth updates/checks. Required the creation of a static
5515 RuntimeError instance in case normalizing an exception put the
5516 recursion check value past its limit. Fixes crashers
5517 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005518
Georg Brandl3ee81df2008-05-17 18:14:43 +00005519- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00005532- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005533 __*__ attributes. (Some already existed, e.g., __doc__ and
5534 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005535
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005536- Add -3 option to the interpreter to warn about features that are
5537 deprecated and will be changed/removed in Python 3.0.
5538
Georg Brandl2134e752007-05-21 20:34:16 +00005539- Patch #1686487: you can now pass any mapping after '**' in function
5540 calls.
5541
Collin Winter62903052007-05-18 23:11:24 +00005542- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005543 "except E as target:". This is to provide forwards compatibility
5544 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005545
Brett Cannon229cee22007-05-05 01:34:02 +00005546- Deprecate BaseException.message as per PEP 352.
5547
Georg Brandl3ee81df2008-05-17 18:14:43 +00005548- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005549 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005550
Vinay Sajip8549ce32007-05-06 17:53:37 +00005551- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005552 setting a plain string, ie don't expand to single letter identifiers.
5553
Raymond Hettinger13936692007-04-11 18:40:58 +00005554- Request #1191699: Slices can now be pickled.
5555
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005556- Request #1193128: str.translate() now allows a None argument for
5557 translations that only remove characters without re-mapping the
5558 remaining characters.
5559
Georg Brandl5cb76c12007-03-21 09:00:39 +00005560- Patch #1682205: a TypeError while unpacking an iterable is no longer
5561 masked by a generic one with the message "unpack non-sequence".
5562
Neal Norwitzaa754b72007-03-21 06:39:48 +00005563- Remove unused file Python/fmod.c.
5564
Guido van Rossum143b5642007-03-23 04:58:42 +00005565- Bug #1683368: The object.__init__() and object.__new__() methods are
5566 now stricter in rejecting excess arguments. The only time when
5567 either allows excess arguments is when it is not overridden and the
5568 other one is. For backwards compatibility, when both are
5569 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005570 warning later). Also, type.__init__() insists on the same signature
5571 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005572
Georg Brandl3ee81df2008-05-17 18:14:43 +00005573- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5574 object to complex using its __complex__() method before falling back
5575 to the __float__() method. Therefore, the functions in the cmath
5576 module now can operate on objects that define a __complex__()
5577 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006651 time so that opening a database previously created with the DB_DUP
6652 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6653 opens. Specifically: dictionary assignment to a DB object will
6654 replace all values for a given key when the database allows
6655 duplicate values. DB users should use DB.put(k, v) when they want
6656 to store duplicates; not DB[k] = v.

6663 characters with ASCII value less than 32. Also, it correctly quotes
6664 dots only if they occur on a single line, as opposed to the previous
6665 behavior of quoting dots if they are the second character of any
6666 line.
