358 thread-local storage key.
359
Victor Stinnercaafd772010-09-08 10:51:01 +0000360- Issue #4947: The write() method of sys.stdout and sys.stderr uses their

362 the same behaviour than the print statement.
363
Antoine Pitrou9cf85f12010-09-01 21:17:34 +0000364- Issue #9737: Fix a crash when trying to delete a slice or an item from

489 handles non-blocking readinto() returning None correctly.
490

493 fix various SSLSocket methods to raise socket.error rather than an
494 unhelpful TypeError when called on an unconnected socket. Original patch
495 by Andrew Bennetts.

503 ZipFile.open()) could return more bytes than requested.
504
Raymond Hettinger20397532010-09-12 02:11:45 +0000505- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
506 This prevents user-created self-referencing ordered dictionaries from
507 becoming permanently uncollectable GC garbage. The downside is that
508 removing __del__ means that the internal doubly-linked list has to wait for
509 GC collection rather than freeing memory immediately when the refcnt drops
510 to zero.
511
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000512- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

Raymond Hettingerffd2a422010-09-10 10:47:22 +0000514 value.
515
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000516- Issue #9792: In case of connection failure, socket.create_connection()
517 would swallow the exception and raise a new one, making it impossible
518 to fetch the original errno, or to filter timeout errors. Now the
519 original error is re-raised.
520
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000521- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
522 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
523 be updated back after the system call. Original patch by Brian Brazil.
524
Antoine Pitroudca9de92010-09-04 17:52:26 +0000525- Issue #1100562: Fix deep-copying of objects derived from the list and
526 dict types. Patch by Michele Orrù and Björn Lindqvist.
527

529 ConfigParser.write.
530
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000531- Issue #808164: Fixed socket.close to avoid references to globals, to
532 avoid issues when socket.close is called from a __del__ method.
533
Terry Reedyd2d2ae92010-11-11 23:22:19 +0000534- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which

539 falling into recursion.
540
R. David Murray7c4bf552010-08-25 01:45:57 +0000541- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
542 character years even if the message contains RFC822 two character years.
543
Daniel Stutzbach91287322010-08-24 21:09:30 +0000544- Issue #8750: Fixed MutableSet's methods to correctly handle
545 reflexive operations, namely x -= x and x ^= x.
546
Victor Stinnercaafd772010-09-08 10:51:01 +0000547- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing

557
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000558- Issue #9617: Signals received during a low-level write operation aren't
559 ignored by the buffered IO layer anymore.
560
Benjamin Peterson52c36052010-08-21 03:03:22 +0000561- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
562 are not held onto after they are deleted elsewhere.
563
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000564- Issue #9626: the view methods for collections.OrderedDict() were returning
565 the unordered versions inherited from dict. Those methods are now
566 overridden to provide ordered views.
567
Éric Araujo0389ae62010-08-14 03:07:46 +0000568- Issue #8688: MANIFEST files created by distutils now include a magic
569 comment indicating they are generated. Manually maintained MANIFESTs
570 without this marker will not be overwritten or removed.
571
Antoine Pitroue1436d12010-08-12 15:25:51 +0000572- Issue #7467: when reading a file from a ZIP archive, its CRC is checked

574 case in Python 2.5 and earlier).
575
Antoine Pitroucb4f47c2010-08-11 13:40:17 +0000576- Issue #9550: a BufferedReader could issue an additional read when the

578 when the underlying raw IO channel was e.g. a socket. Report and original
579 patch by Jason V. Miller.
580
Fred Drake0a1fa0e2010-08-10 13:09:54 +0000581- Issue #9551: Don't raise TypeError when setting the value to None for

Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000968- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
969 start byte and the continuation byte(s) are now considered invalid, instead
970 of the number of bytes specified by the start byte.
971 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
972 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
973 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
974 Previous versions returned a single u'\ufffd'.

978 arises from the "Overriding __eq__ blocks inheritance ..." warning

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000982- Issue #8748: Fix two issues with comparisons between complex and integer
983 objects. (1) The comparison could incorrectly return True in some cases
984 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
985 (2) The comparison raised an OverflowError for large integers, leading
986 to unpredictable exceptions when combining integers and complex objects
987 in sets or dicts.

1355
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001356- Issue #8329: Don't return the same lists from select.select when no fds are
1357 changed.
1358

1370 with a non-empty format string. This is an effort to future-proof user
1371 code. If a derived class does not currently implement __format__ but later
1372 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001373 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001374 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001424- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1425 InvalidOperation instead of returning False. (Comparisons involving a quiet
1426 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1427 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00001429- Issue #2531: Comparison operations between floats and Decimal instances now
1430 return a result based on the numeric values of the operands; previously they
1431 returned an arbitrary result based on the relative ordering of id(float) and
1432 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001434- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001435 argument `-` which tells it to read files to compile from stdin. Each line is
1436 read on demand and the named file is compiled immediately. (Original patch by
1437 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00001446- Comparisons using one of <, <=, >, >= between a complex instance and a
1447 Fractions instance now raise TypeError instead of returning True/False. This
1448 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1449 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00001553- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1554 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the

Georg Brandlfee0f442010-05-22 21:26:21 +00001556 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1557 inconsistent: __int__ was used for some integer codes but not for others, and
1558 the set of integer codes for which it was used differed between native packing
1559 and standard packing.)

1868 position to the given argument, which goes against the tradition of

Georg Brandlba83f822010-03-14 09:50:54 +00001886- Issue #7748: Since unicode values are supported for some metadata options in

1888 encoded string for them. This ensures that the upload and register commands

Mark Dickinson1b34d252010-01-01 17:27:30 +00001972- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001973 DeprecationWarning when passed a float argument where an integer was expected.
1974 These functions and methods now raise TypeError instead. The majority of the
1975 effects of this change are in the extension modules, but some core functions
1976 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1977 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00002139- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
2140 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002141
Georg Brandlba83f822010-03-14 09:50:54 +00002142- Issue #3382: 'F' formatting for float and complex now convert the result to
2143 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
2144 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002145
Georg Brandlba83f822010-03-14 09:50:54 +00002146- Remove switch from "%f" formatting to "%g" formatting for floats larger than
2147 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00002148
Georg Brandlba83f822010-03-14 09:50:54 +00002149- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
2150 1e-100 used to raise OverflowError, but now gives the requested 120
2151 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00002152
Georg Brandlba83f822010-03-14 09:50:54 +00002153- Add Py3k warnings for parameter names in parentheses.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +00002154
Georg Brandlba83f822010-03-14 09:50:54 +00002155- Issue #7362: Give a proper error message for ``def f((x)=3): pass``.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +00002156
Georg Brandlba83f822010-03-14 09:50:54 +00002157- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
2158 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00002159
Georg Brandlba83f822010-03-14 09:50:54 +00002160- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2161 decimal string that's guaranteed to round back to x under correct rounding
2162 (with round-half-to-even rounding mode). Previously it gave a string based on
2163 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2164 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2165 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002166
Georg Brandlba83f822010-03-14 09:50:54 +00002167- Issue #7117: On almost all platforms: float-to-string and string-to-float
2168 conversions within Python are now correctly rounded. Places these conversions
2169 occur include: str for floats and complex numbers; the float and complex
2170 constructors; old-style and new-style numeric formatting; serialization and
2171 deserialization of floats and complex numbers using marshal, pickle and json;
2172 parsing of float and imaginary literals in Python code; Decimal-to-float
2173 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002174
Georg Brandlba83f822010-03-14 09:50:54 +00002175 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2176 providing correctly-rounded strtod and dtoa C functions. This code is
2177 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2178 the C compiler. There may be a small number of platforms on which correct
2179 operation of this code cannot be guaranteed, so the code is not used: notably,
2180 this applies to platforms where the C double format is not IEEE 754 binary64,
2181 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2182 and Python's configure script is unable to determine how to change the FPU
2183 precision. On these platforms conversions use the platform strtod and dtoa,
2184 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002185
Georg Brandlba83f822010-03-14 09:50:54 +00002186- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2187 uses the correctly-rounded string <-> float conversions described above (when
2188 available), and so produces correctly rounded results that will display nicely
2189 under the float repr. There are two related small changes: (1) round now
2190 accepts any class with an ``__index__()`` method for its second argument (but
2191 no longer accepts floats for the second argument), and (2) an excessively
2192 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2193 raises an exception.
Mark Dickinsonbd15a062009-11-18 19:33:35 +00002194
Philip Jenveyfab8be22009-11-17 02:42:26 +00002195- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
2196
Georg Brandlba83f822010-03-14 09:50:54 +00002197- Fix several issues with ``compile()``. The input can now contain Windows and
2198 Mac newlines and is no longer required to end in a newline.
Benjamin Petersone36199b2009-11-12 23:39:44 +00002199
Georg Brandlba83f822010-03-14 09:50:54 +00002200- Remove length limitation when constructing a complex number from a unicode
2201 string.
Mark Dickinsonc04c7c52009-10-26 22:28:14 +00002202
Georg Brandlba83f822010-03-14 09:50:54 +00002203- Issue #7244: ``itertools.izip_longest()`` no longer ignores exceptions raised

Georg Brandlba83f822010-03-14 09:50:54 +00002208- Issue #1722344: ``threading._shutdown()`` is now called in ``Py_Finalize()``,
2209 which fixes the problem of some exceptions being thrown at shutdown when the
2210 interpreter is killed. Patch by Adam Olsen.

2219 module is the only object holding a reference to it.
Benjamin Peterson196b0922009-10-15 15:44:46 +00002220
Georg Brandlba83f822010-03-14 09:50:54 +00002221- Issue #1754094: Improve the stack depth calculation in the compiler. There
2222 should be no other effect than a small decrease in memory use. Patch by
2223 Christopher Tur Lesniewski-Laas.
Neil Schemenauer7fdd1cb2009-10-14 17:17:14 +00002224
Georg Brandlba83f822010-03-14 09:50:54 +00002225- Issue #7084: Fix a (very unlikely) crash when printing a list from one thread,
2226 and mutating it from another one. Patch by Scott Dial.
Antoine Pitroubeaf6a02009-10-11 21:03:26 +00002227
Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +00002228- Issue #1571184: The Unicode database contains properties for more characters.
2229 The tables for code points representing numeric values, white spaces or line
2230 breaks are now generated from the official Unicode Character Database files,
2231 and include information from the Unihan.txt file.

Georg Brandlba83f822010-03-14 09:50:54 +00002340- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2341 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2342 but with at least one decimal point and with a default precision
2343 of 12. Previously, the behavior the same but with a default precision of 6.
2344 This more closely matches ``str()``, and reduces surprises when adding
2345 alignment flags to the empty presentation type. This also affects the new
2346 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00002411 untrackable objects are not tracked by the garbage collector. This can reduce
2412 the size of collections and therefore the garbage collection overhead on

2420 internal representation of integers, for performance reasons. Base 2**30 is
2421 enabled by default on 64-bit machines. Add --enable-big-digits option to
2422 configure, which overrides the default. Add sys.long_info structseq to

2454
Georg Brandl29c6a282009-04-05 20:23:13 +00002455- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00002456 were suppressing all exceptions. These include list(), filter(), map(),

2458
Benjamin Peterson596d3062009-01-19 15:42:23 +00002459- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Georg Brandlba83f822010-03-14 09:50:54 +00002486- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2487 existing .py counterpart, override the co_filename attributes of all code
2488 objects if the original filename is obsolete (which can happen if the file has

2543
Georg Brandlba83f822010-03-14 09:50:54 +00002544- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2545 file objects with closefd=False. The file descriptor is still kept open but

3979 ``printf`` function, whereas PyString_FromFormat has an independent
3980 implementation and uses "%zd" on all platforms for size_t values.
3981 This makes a difference on win64, where ``printf`` needs "%Id" to display
3982 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00003984- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
3985 error.
3986
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00003987- Issue #3777: long() applied to a float object now always return a long
3988 object; previously an int would be returned for small values. the __long__
3989 method is allowed to return either an int or a long, but the behaviour of
3990 float objects should not change to respect backward compatibility.
3991
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003992- Issue #3751: str.rpartition would perform a left-partition when called with
3993 a unicode argument.
3994
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00003995- Issue #3683: Fix compilation when --without-threads is given.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003997- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00003998 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003999 was correctly parsed but parsing of subsequent arguments failed.
4000
Vinay Sajip35e3b032008-09-01 14:33:59 +00004001- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004002 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4003 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4004 when given a tuple of classes as second argument, were looking up
4005 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4006 type object.
4007
Neal Norwitz18aa3882008-08-24 05:04:52 +00004008- Fix crashes on memory allocation failure found with failmalloc.

Christian Heimes7d4c3172008-08-22 19:47:25 +00004016- Silenced another compiler warning about a used but not defined
4017 function 'stringlib_contains_obj'.
4018

Brett Cannon1eaf0742008-09-02 01:25:16 +00004077 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4078 for catch_warnings() also led to an improvement in the raising of a
4079 DeprecationWarning related to warnings.warn_explicit().
4080

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004145What's New in Python 2.6 beta 3?
4146================================
4147
Barry Warsaw07a4a382008-08-21 01:15:08 +00004148*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004149
4150Core and Builtins
4151-----------------
4152
Guido van Rossumf8402962008-08-20 15:01:50 +00004153- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4154 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4155 extensions do not automatically benefit from the class attribute
4156 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4157 to their tp_flags field if they care. This is a backwards
4158 compatibility feature; in 3.0, all types will use the cache by
4159 default.
4160
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004161- Keyword arguments can now follow starred arguments. (``f(a, *args,
4162 keyword=23)`` is now valid syntax.)
4163
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004164- ctypes function pointers that are COM methods have a boolean True
4165 value again.
4166
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004167- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4168 by denying s# to parse objects that have a releasebuffer procedure,
4169 and introducing s*.
4170
Georg Brandl1e13ea92008-08-11 09:07:59 +00004171- Issue #3537: Fix an assertion failure when an empty but presized dict
4172 object was stored in the freelist.
4173
Mark Dickinsonb6467572008-08-04 21:30:09 +00004174- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4175 ValueError consistently across platforms.
4176
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004177- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4178 (64bit Unix, for example), unichr() would truncate its argument and return
4179 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4180
Neal Norwitze7d8be82008-07-31 17:17:14 +00004181- Apply security patches from Apple.
4182
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004183- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4184 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4185
Antoine Pitrou92f82162008-07-25 22:22:08 +00004186- Issue #1819: function calls with several named parameters are now on
4187 average 35% faster (as measured by pybench).
4188
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004189- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4190 the python debugger steps into a class statement: the free variables (local
4191 variables defined in an outer scope) would be deleted from the outer scope.
4192
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004193- Issue #2620: Overflow checking when allocating or reallocating memory
4194 was not always being done properly in some python types and extension
4195 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4196 all been updated to perform better checks and places in the code that
4197 would previously leak memory on the error path when such an allocation
4198 failed have been fixed.

4202
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004203- Issue #3612: Added some missing basic types in ctypes.wintypes.
4204
Benjamin Petersone977ad42008-08-20 01:42:01 +00004205- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4206 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4207
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004208- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4209 version reported by these tools does not necessarily follow the python
4210 version numbering scheme, so the module is less strict when parsing it.
4211
Nick Coghlanf70385a2008-08-18 12:42:46 +00004212- Issue #2235: Added Py3k warnings for types which will become unhashable
4213 under the stricter __hash__ inheritance rules in 3.0. Several types
4214 which did not meet the rules for hash invariants and were already
4215 unhashable in 3.0 have now been explicitly flagged as unhashable in
4216 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4217 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4218
Brett Cannon88f801d2008-08-18 00:46:22 +00004219- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

4227
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004228- Issue #3575: Incremental decoder's decode function now takes bytearray
4229 by using 's*' instead of 't#'.
4230
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004231- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004232 fails unicode conversion on 2nd parameter. (windows only)
4233
Georg Brandl222e2082010-08-01 22:27:39 +00004234- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004235 in a redirect.

Brett Cannon721b1452008-08-16 22:00:27 +00004238 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004239
Facundo Batistaeb90b782008-08-16 14:44:07 +00004240- Issue #2776: fixed small issue when handling an URL with double slash
4241 after a 302 response in the case of not going through a proxy.
4242
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004243- Issue #2676: in the email package, content-type parsing was hanging on
4244 pathological input because of quadratic or exponential behaviour of a
4245 regular expression.
4246
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004247- Issue #3476: binary buffered reading through the new "io" library is now
4248 thread-safe.
4249
Brett Cannonbf3157b2008-08-14 05:00:03 +00004250- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4251 since mimetools itself is deprecated. Because modules are cached, all
4252 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4253
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004254- Issue #3134: shutil referenced undefined WindowsError symbol.
4255
Robert Schuppenies14646332008-08-10 11:01:53 +00004256- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4257 menu entries were not deleted.
4258
Brett Cannon83e81842008-08-09 23:30:55 +00004259- Copied the implementation of reduce() to _functools.reduce() to have a
4260 version that did not raise a DeprecationWarning under -3.
4261
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004262- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4263 a MemoryError rather than silently stop the iteration.

Guido van Rossum59ce9012008-08-09 14:55:34 +00004265- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4266 to _sre.compile() will now be rejected. This should not affect anybody
4267 since the re.compile() function never generates invalid re-bytecode.

Antoine Pitroude781a42008-08-09 12:43:23 +00004288 asking for a specific length. This problem only affected files opened
4289 using the new "io" module, not the built-in open() function.

4332
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004333- Issue #643841: The language reference now provides more detailed

4345-----------------
4346
Georg Brandl3e483f62008-07-16 22:57:41 +00004347- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4348 its methods now allow for items objects that can be converted to
4349 an integer using operator.index().
4350
Mark Dickinson64b7e502008-07-16 09:40:03 +00004351- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4352 produced a ValueError instead of giving the correct float.
4353
Eric Smitha5fa5a22008-07-16 00:11:49 +00004354- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4355 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4356
Mark Dickinson7103aa42008-07-15 19:08:33 +00004357- Issue #3008: the float type has a new instance method 'float.hex'
4358 and a new class method 'float.fromhex' to convert floating-point
4359 numbers to and from hexadecimal strings, respectively.
4360
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004361- Issue #2235: __hash__ is once again inherited by default. To allow
4362 collections.Hashable to remain meaningful in the presence of the
4363 default hash implementation (object.__hash__), it is now possible
4364 to explicit block inheritance of hash by setting __hash__=None at
4365 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4366 level.
4367
Nick Coghlanb028f502008-07-13 14:52:36 +00004368- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4369 the parent module cannot be found while performing an absolute import.
4370 This means that an incorrectly defined __package__ attribute will
4371 now only prevent relative imports in that module rather than causing
4372 all imports from that module to fail.
4373
Nick Coghlan14ff9942008-07-08 14:21:42 +00004374- Issue #2517: Allow unicode messages in Exceptions again by correctly

4384 another thread's dictionary.
4385
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004386- Issue #3004: Minor change to slice.indices(): the start and stop
4387 arguments are now treated identically, making the behaviour easier
4388 to describe and understand. For example, slice(None, -10,
4389 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4390 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4391 10, -1).
4392
Georg Brandl278fc502008-07-19 12:46:12 +00004393- Issue #3219: Calling a function with repeated keyword arguments,
4394 f(a=2, a=23), would not cause a syntax error. This was a regression
4395 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00004397- Issue #2862: Make int and float freelist management consistent with
4398 other freelists. Changes their CompactFreeList apis into

4405 api functions without holding the GIL, which could lead to a fatal
4406 error when they failed.
4407
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004408- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004433- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4434 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004435 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004436 content-length. The problem had been corrected in the 2.4 branch, but never
4437 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004452- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

4840
Brett Cannonb61d8012008-05-11 23:39:04 +00004841- ``Lib/lib-old`` is now added to sys.path.
4842
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004843- On MacOS X it is now possible to install the framework in 64-bit
4844 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004845 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004846
4847 This is controlled by the configure argument ``--with-universal-archs``:
4848
4849 - ``--with-universal-archs=all``: install 4-way universal
4850
4851 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4852
4853 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4854
4855 This option should be used in combination with ``--enable-universalsdk=``.
4856
4857 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00004866
4867- The PyString functions have been renamed to PyBytes. A batch of
4868 defines were added so that the linker still sees the original
4869 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004907- Issue #1631171: Re-implement the 'warnings' module in C (the
4908 original Python code has been kept as backup). This will allow for
4909 using the 'warning's machinery in such places as the parser where
4910 use of pure Python code is not possible. Both the ``showarning()``
4911 and ``formatwarning()`` gain an optional 'line' argument which is
4912 not called by default for backwards-compatibility reasons. Setting
4913 ``warnings.showwarning()`` to an implementation that lacks support
4914 for the ``line`` argument will raise a DeprecationWarning.

4938
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004939- The getpass module has been improved on Unix. It now uses /dev/tty
4940 by default and uses stderr instead of stdout. A GetPassWarning is
4941 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00004942

Georg Brandl3ee81df2008-05-17 18:14:43 +00004956- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004957 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004977- Issue #2550: The approach used by client/server code for obtaining
4978 ports to listen on in network-oriented tests has been refined in an
4979 effort to facilitate running multiple instances of the entire
4980 regression test suite in parallel without issue.
4981 test_support.bind_port() has been fixed such that it will always
4982 return a unique port -- which wasn't always the case with the
4983 previous implementation, especially if socket options had been set
4984 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4985 new implementation of bind_port() will actually raise an exception
4986 if it is passed an AF_INET/SOCK_STREAM socket with either the
4987 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4988 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4989 the socket it's been passed. This currently only applies to
4990 Windows. This option prevents any other sockets from binding to the
4991 host/port we've bound to, thus removing the possibility of the
4992 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4993 when a second SOCK_STREAM socket binds and accepts to a host/port
4994 that's already been bound by another socket. The optional preferred
4995 port parameter to bind_port() has been removed. Under no
4996 circumstances should tests be hard coding ports!
4997
4998 test_support.find_unused_port() has also been introduced, which will
4999 pass a temporary socket object to bind_port() in order to obtain an
5000 unused port. The temporary socket object is then closed and
5001 deleted, and the port is returned. This method should only be used
5002 for obtaining an unused port in order to pass to an external program
5003 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5004 a parameter to a server-oriented class that doesn't give you direct
5005 access to the underlying socket used.
5006
5007 Finally, test_support.HOST has been introduced, which should be used
5008 for the host argument of any relevant socket calls (i.e. bind and
5009 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005010
5011 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005012 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005013 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5014 test_asynchat and test_socket_ssl.
5015
Georg Brandl3ee81df2008-05-17 18:14:43 +00005016 It is now possible for multiple instances of the regression test
5017 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005296- Added the future_builtins module, which contains hex() and oct().
5297 These are the PEP 3127 version of these functions, designed to be
5298 compatible with the hex() and oct() builtins from Python 3.0. They
5299 differ slightly in their output formats from the existing, unchanged
5300 Python 2.6 builtins. The expected usage of the future_builtins
5301 module is:
5302 from future_builtins import hex, oct
5303
Eric Smith7ef40bf2008-02-20 23:34:22 +00005304- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5305 exponents for exponents with absolute value < 100. Follows C99
5306 standard. This is a change on Windows, which would use 3 digits.
5307 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5308 so that any alterations it does to the resulting string will be
5309 available in stringlib/formatter.h (for float.__format__).
5310
Eric Smith5a3c1352008-02-19 13:21:56 +00005311- Implemented PEP 3101, Advanced String Formatting. This adds a new
5312 builtin format(); a format() method for str and unicode; a
5313 __format__() method to object, str, unicode, int, long, float, and
5314 datetime; the class string.Formatter; and the C API
5315 PyObject_Format().
5316
Georg Brandl3ee81df2008-05-17 18:14:43 +00005317- Fixed several potential crashes, all caused by specially crafted
5318 __del__ methods exploiting objects in temporarily inconsistent
5319 state.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00005321- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005322 prevent a possible crash: an Abstract Base Class would try to access
5323 a slot on a registered virtual subclass.

5329 in order to allow pymalloc to free more arenas. Python may give back
5330 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005331
Georg Brandl3ee81df2008-05-17 18:14:43 +00005332- Issue #2045: Fix an infinite recursion triggered when printing a
5333 subclass of collections.defaultdict, if its default_factory is set
5334 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005335
Christian Heimesf75dbef2008-02-08 00:11:31 +00005336- Fixed a minor memory leak in dictobject.c. The content of the free
5337 list was not freed on interpreter shutdown.
5338
Georg Brandl21e99f42010-03-07 15:23:59 +00005339- Limit free list of method and built-in function objects to 256

5343 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005344 to compact the internal free lists of pre-allocted ints and floats.
5345
Georg Brandl3ee81df2008-05-17 18:14:43 +00005346- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5347 calls. Python expected the return type int but the fork familie

Georg Brandl3ee81df2008-05-17 18:14:43 +00005359- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5360 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005361
Georg Brandl3ee81df2008-05-17 18:14:43 +00005362- Patch #1473257: generator objects gain a gi_code attribute. This is
5363 the same object as the func_code attribute of the function that
5364 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005365
Georg Brandl3ee81df2008-05-17 18:14:43 +00005366- Issue #1920: "while 0" statements were completely removed by the
5367 compiler, even in the presence of an "else" clause, which is
5368 supposed to be run when the condition is false. Now the compiler
5369 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005370
Guido van Rossumeead05f2008-01-24 18:21:02 +00005371- A few crashers fixed: weakref_in_del.py (issue #1377858);
5372 loosing_dict_ref.py (issue #1303614, test67.py);
5373 borrowed_ref_[34].py (not in tracker).
5374
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005375- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005376 suppressed while an extension is loaded by calling SetErrorMode in
5377 dynload_win.c. The error is still reported properly.
5378
Georg Brandl3ee81df2008-05-17 18:14:43 +00005379- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005380 several extension methods and modules do not work without unicode
5381 support.
5382
Georg Brandl26543b12008-01-21 18:36:51 +00005383- Issue #1882: when compiling code from a string, encoding cookies in the
5384 second line of code were not always recognized correctly.
5385
Georg Brandl14404b62008-01-19 19:27:05 +00005386- Issue #1679: "0x" was taken as a valid integer literal.
5387
Georg Brandl6caad7d2008-01-26 14:19:22 +00005388- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005389 added.
5390
Christian Heimesc94e2b52008-01-14 04:13:37 +00005391- sys.float_info / PyFloat_GetInfo: The floating point information
5392 object was converted from a dict to a specialized structseq object.
5393
Georg Brandl3ee81df2008-05-17 18:14:43 +00005394- Patch #1816: Added sys.flags structseq. It exposes the status of
5395 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005396
Georg Brandl3ee81df2008-05-17 18:14:43 +00005397- Objects/structseq.c: Implemented new structseq representation. The
5398 patch makes structseqs (e.g. the return value of os.stat) more
5399 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005400
Georg Brandl3ee81df2008-05-17 18:14:43 +00005401- Patch #1700288: added a type attribute cache that caches method
5402 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005403
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005404- Bug #1776: __import__() no longer accepts filenames on any platform.
5405 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005406
Georg Brandlaed6c662008-01-07 17:25:53 +00005407- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5408
Georg Brandl3ee81df2008-05-17 18:14:43 +00005409- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5410 envvar and sys.dont_write_bytecode attribute. All these can be set
5411 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005412
Georg Brandl3ee81df2008-05-17 18:14:43 +00005413- Improve some exception messages when Windows fails to load an
5414 extension module. Now we get for example '%1 is not a valid Win32
5415 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005416

Christian Heimes0a8143f2007-12-18 23:22:54 +00005422- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005423 and INF. float("nan"), float("inf") and float("-inf") now work on
5424 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005425
Georg Brandl3ee81df2008-05-17 18:14:43 +00005426- Compiler now generates simpler and faster code for dictionary
5427 literals. The oparg for BUILD_MAP now indicates an estimated
5428 dictionary size. There is a new opcode, STORE_MAP, for adding
5429 entries to the dictionary.

5441
Nick Coghlanef01d822007-12-03 12:55:17 +00005442- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00005458- Patch #1739468: Directories and zipfiles containing a __main__.py
5459 file can now be directly executed by passing their name to the
5460 interpreter. The directory/zipfile is automatically inserted as the
5461 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005462
Georg Brandl3ee81df2008-05-17 18:14:43 +00005463- Issue #1265: Fix a problem with sys.settrace, if the tracing
5464 function uses a generator expression when at the same time the
5465 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005466
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005467- sets and frozensets now have an isdisjoint() method.
5468
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005469- optimize the performance of builtin.sum().
5470
Neal Norwitz44f326e2007-10-05 05:29:17 +00005471- Fix warnings found by the new version of the Coverity checker.
5472
Georg Brandl21e99f42010-03-07 15:23:59 +00005473- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005474 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5475 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005476
Georg Brandl3ee81df2008-05-17 18:14:43 +00005477- Issue #1686386: Tuple's tp_repr did not take into account the
5478 possibility of having a self-referential tuple, which is possible
5479 from C code. Nor did object's tp_str consider that a type's tp_str
5480 could do something that could lead to an inifinite recursion.
5481 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5482 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005483
Georg Brandl3ee81df2008-05-17 18:14:43 +00005484- Issue #1164: It was possible to trigger deadlock when using the
5485 'print' statement to write to a file since the GIL was not released
5486 as needed. Now PyObject_Print() does the right thing along with
5487 various tp_print implementations of the built-in types and those in
5488 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005489
Georg Brandl3ee81df2008-05-17 18:14:43 +00005490- Issue #1147: Exceptions were directly allowing string exceptions in
5491 their throw() method even though string exceptions no longer
5492 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005493
Georg Brandl3ee81df2008-05-17 18:14:43 +00005494- Issue #1096: Prevent a segfault from getting the repr of a very
5495 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005496
Brett Cannon1e534b52007-09-07 04:18:30 +00005497- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005498 PyObject_Call() never calling back out to Python code to trigger
5499 recursion depth updates/checks. Required the creation of a static
5500 RuntimeError instance in case normalizing an exception put the
5501 recursion check value past its limit. Fixes crashers
5502 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005503
Georg Brandl3ee81df2008-05-17 18:14:43 +00005504- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00005517- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005518 __*__ attributes. (Some already existed, e.g., __doc__ and
5519 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005520
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005521- Add -3 option to the interpreter to warn about features that are
5522 deprecated and will be changed/removed in Python 3.0.
5523
Georg Brandl2134e752007-05-21 20:34:16 +00005524- Patch #1686487: you can now pass any mapping after '**' in function
5525 calls.
5526
Collin Winter62903052007-05-18 23:11:24 +00005527- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005528 "except E as target:". This is to provide forwards compatibility
5529 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005530
Brett Cannon229cee22007-05-05 01:34:02 +00005531- Deprecate BaseException.message as per PEP 352.
5532
Georg Brandl3ee81df2008-05-17 18:14:43 +00005533- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005534 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005535
Vinay Sajip8549ce32007-05-06 17:53:37 +00005536- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005537 setting a plain string, ie don't expand to single letter identifiers.
5538
Raymond Hettinger13936692007-04-11 18:40:58 +00005539- Request #1191699: Slices can now be pickled.
5540
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005541- Request #1193128: str.translate() now allows a None argument for
5542 translations that only remove characters without re-mapping the
5543 remaining characters.
5544
Georg Brandl5cb76c12007-03-21 09:00:39 +00005545- Patch #1682205: a TypeError while unpacking an iterable is no longer
5546 masked by a generic one with the message "unpack non-sequence".
5547
Neal Norwitzaa754b72007-03-21 06:39:48 +00005548- Remove unused file Python/fmod.c.
5549
Guido van Rossum143b5642007-03-23 04:58:42 +00005550- Bug #1683368: The object.__init__() and object.__new__() methods are
5551 now stricter in rejecting excess arguments. The only time when
5552 either allows excess arguments is when it is not overridden and the
5553 other one is. For backwards compatibility, when both are
5554 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005555 warning later). Also, type.__init__() insists on the same signature
5556 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005557
Georg Brandl3ee81df2008-05-17 18:14:43 +00005558- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5559 object to complex using its __complex__() method before falling back
5560 to the __float__() method. Therefore, the functions in the cmath
5561 module now can operate on objects that define a __complex__()
5562 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005564- Patch #1623563: allow __class__ assignment for classes with
5565 __slots__. The old and the new class are still required to have the
5566 same slot names.

5572 ``object.__reduce_ex__()`` is called with an object that is faking
5573 its type.

5579
Georg Brandl7b9c5552007-03-12 14:30:05 +00005580- Bug #1678647: write a newline after printing an exception in any
5581 case, even when converting the value to a string failed.
5582
Georg Brandl871f1bc2007-03-12 13:17:36 +00005583- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005584 its argument, if it exists. If not, it will work like before. This
5585 allows customizing the output of dir() in the presence of a
5586 __getattr__().

Georg Brandl4e933132006-09-06 20:05:58 +00005701- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Facundo Batistad918a652007-04-24 13:54:38 +00006109- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006110 the client's request was successfully received, understood, and

6124
Vinay Sajip8549ce32007-05-06 17:53:37 +00006125- Patch #1676823: Added create_connection() to socket.py, which may be

Georg Brandl3ee81df2008-05-17 18:14:43 +00006151 AttributeError instead of an IOError when the server's response
6152 didn't contain a valid HTTP status line.

6243 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00006636 time so that opening a database previously created with the DB_DUP
6637 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6638 opens. Specifically: dictionary assignment to a DB object will
6639 replace all values for a given key when the database allows
6640 duplicate values. DB users should use DB.put(k, v) when they want
6641 to store duplicates; not DB[k] = v.

6648 characters with ASCII value less than 32. Also, it correctly quotes
6649 dots only if they occur on a single line, as opposed to the previous
6650 behavior of quoting dots if they are the second character of any
6651 line.
