390 This prevents user-created self-referencing ordered dictionaries from
391 becoming permanently uncollectable GC garbage. The downside is that
392 removing __del__ means that the internal doubly-linked list has to wait for
393 GC collection rather than freeing memory immediately when the refcnt drops
394 to zero.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00001213 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

1237
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001238- Issue #7301: Add environment variable $PYTHONWARNINGS.
1239
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001240- Issue #8329: Don't return the same lists from select.select when no fds are
1241 changed.
1242
Georg Brandlfee0f442010-05-22 21:26:21 +00001243- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001244 on 64-bit machines. The shift count for either left or right shift is
1245 permitted to be up to sys.maxsize.
1246
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001247- Ensure that tokenization of identifiers is not affected by locale.

1252
Georg Brandlfee0f442010-05-22 21:26:21 +00001253- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1254 with a non-empty format string. This is an effort to future-proof user
1255 code. If a derived class does not currently implement __format__ but later
1256 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001257 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001258 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001259
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001260- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00001273- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00001274 (SIGINT). If an error occurs while importing the site module, the error is

Georg Brandlfee0f442010-05-22 21:26:21 +00001291- Issue #8257: The Decimal construct now accepts a float instance directly,
1292 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001293
1294 >>> Decimal(1.1)
1295 Decimal('1.100000000000000088817841970012523233890533447265625')
1296
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001297- collections.Counter() now supports a subtract() method.
1298
Georg Brandlfee0f442010-05-22 21:26:21 +00001299- The functools module now has a total_ordering() class decorator to simplify
1300 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00001302- The functools module also adds cmp_to_key() as a tool to transition old-style
1303 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001304

Georg Brandlfee0f442010-05-22 21:26:21 +00001308- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1309 InvalidOperation instead of returning False. (Comparisons involving a quiet
1310 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1311 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001312
Georg Brandlfee0f442010-05-22 21:26:21 +00001313- Issue #2531: Comparison operations between floats and Decimal instances now
1314 return a result based on the numeric values of the operands; previously they
1315 returned an arbitrary result based on the relative ordering of id(float) and
1316 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001317
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001318- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001319 argument `-` which tells it to read files to compile from stdin. Each line is
1320 read on demand and the named file is compiled immediately. (Original patch by
1321 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00001326- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1327 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001328 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001329
Georg Brandlfee0f442010-05-22 21:26:21 +00001330- Comparisons using one of <, <=, >, >= between a complex instance and a
1331 Fractions instance now raise TypeError instead of returning True/False. This
1332 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1333 <=> complex, and complex <=> complex comparisons.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00001388- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001389 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1390 log file to compute the next rollover time. If the log file does not exist,
1391 the current time is used as the basis for the computation.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001432- Issue #8300: When passing a non-integer argument to struct.pack with any
1433 integer format code, struct.pack first attempts to convert the non-integer
1434 using its __index__ method. If that method is non-existent or raises
1435 TypeError it goes on to try the __int__ method, as described below.
1436
Georg Brandlba83f822010-03-14 09:50:54 +00001437- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1438 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1439 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001440 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1441 inconsistent: __int__ was used for some integer codes but not for others, and
1442 the set of integer codes for which it was used differed between native packing
1443 and standard packing.)

1696 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1697 returning NULL. The macro now returns a statically allocated empty string
1698 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00001751 file position when calling `truncate()`. It would previously change the file
1752 position to the given argument, which goes against the tradition of

1756 class used to represent files stored inside an archive. The new
1757 implementation is significantly faster and can be wrapped in a

1759 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

1772 encoded string for them. This ensures that the upload and register commands
1773 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00002044- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2045 decimal string that's guaranteed to round back to x under correct rounding
2046 (with round-half-to-even rounding mode). Previously it gave a string based on
2047 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2048 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2049 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002050
Georg Brandlba83f822010-03-14 09:50:54 +00002051- Issue #7117: On almost all platforms: float-to-string and string-to-float
2052 conversions within Python are now correctly rounded. Places these conversions
2053 occur include: str for floats and complex numbers; the float and complex
2054 constructors; old-style and new-style numeric formatting; serialization and
2055 deserialization of floats and complex numbers using marshal, pickle and json;
2056 parsing of float and imaginary literals in Python code; Decimal-to-float
2057 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002058
Georg Brandlba83f822010-03-14 09:50:54 +00002059 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2060 providing correctly-rounded strtod and dtoa C functions. This code is
2061 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2062 the C compiler. There may be a small number of platforms on which correct
2063 operation of this code cannot be guaranteed, so the code is not used: notably,
2064 this applies to platforms where the C double format is not IEEE 754 binary64,
2065 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2066 and Python's configure script is unable to determine how to change the FPU
2067 precision. On these platforms conversions use the platform strtod and dtoa,
2068 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002070- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2071 uses the correctly-rounded string <-> float conversions described above (when
2072 available), and so produces correctly rounded results that will display nicely
2073 under the float repr. There are two related small changes: (1) round now
2074 accepts any class with an ``__index__()`` method for its second argument (but
2075 no longer accepts floats for the second argument), and (2) an excessively
2076 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2077 raises an exception.

2227 of 12. Previously, the behavior the same but with a default precision of 6.
2228 This more closely matches ``str()``, and reduces surprises when adding

Georg Brandl29c6a282009-04-05 20:23:13 +00002339- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00002340 were suppressing all exceptions. These include list(), filter(), map(),

2342
Benjamin Peterson596d3062009-01-19 15:42:23 +00002343- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Georg Brandlba83f822010-03-14 09:50:54 +00002370- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2371 existing .py counterpart, override the co_filename attributes of all code
2372 objects if the original filename is obsolete (which can happen if the file has

2427
Georg Brandlba83f822010-03-14 09:50:54 +00002428- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2429 file objects with closefd=False. The file descriptor is still kept open but
2430 the file object behaves like a closed file. The ``FileIO`` object also got a
2431 new readonly attribute ``closefd``.

2450
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002451- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00002452 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00002454- On windows, ``os.chdir()`` given unicode was not working if
2455 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2456 this code path is really executed because I cannot move to such directory on
2457 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002459- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2460 element is temporarily replaced with an equivalent frozenset. But the
2461 eventual KeyError would always report the empty ``frozenset()`` as the missing
2462 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00002482- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2483 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2484 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2485 of using the replace error handler in PyUnicode_DecodeUTF8().
2486
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002487- Issue #3739: The unicode-internal encoder now reports the number of characters

2489
Georg Brandlba83f822010-03-14 09:50:54 +00002490- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

2492 gives improved memory leak detection when running under Valgrind, while taking
2493 advantage of pymalloc at other times.

3859
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003860- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3861 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3862 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3863 ``printf`` function, whereas PyString_FromFormat has an independent
3864 implementation and uses "%zd" on all platforms for size_t values.
3865 This makes a difference on win64, where ``printf`` needs "%Id" to display
3866 64bit values.

3884
Vinay Sajip35e3b032008-09-01 14:33:59 +00003885- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003886 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3887 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3888 when given a tuple of classes as second argument, were looking up
3889 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3890 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003961 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3962 for catch_warnings() also led to an improvement in the raising of a
3963 DeprecationWarning related to warnings.warn_explicit().
3964
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003965- The deprecation warnings for the old camelCase threading API were removed.
3966

3968
Christian Heimesa27a62e2008-08-22 19:55:54 +00003969- Silenced a trivial compiler warning in the sqlite module.
3970
Christian Heimes1cc69632008-08-22 20:10:27 +00003971- Fixed two format strings in the _collections module.
3972

3986 _check_logger_class from multiprocessing.
3987
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003988- Issue #2975: When compiling several extension modules with Visual Studio 2008
3989 from the same python interpreter, some environment variables would grow
3990 without limit.
3991
Benjamin Peterson37346b22008-08-23 20:27:43 +00003992- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
3993 exploitation of poor argument checking.
3994
Gerhard Häringef2276b2008-09-12 13:54:06 +00003995- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
3996
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00003997- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
3998 remaining ones have "pysqlite_" prefix.
3999
Gerhard Häringe6872eb2008-09-12 22:33:22 +00004000- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004029What's New in Python 2.6 beta 3?
4030================================
4031
Barry Warsaw07a4a382008-08-21 01:15:08 +00004032*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004033
4034Core and Builtins
4035-----------------
4036
Guido van Rossumf8402962008-08-20 15:01:50 +00004037- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4038 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4039 extensions do not automatically benefit from the class attribute
4040 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4041 to their tp_flags field if they care. This is a backwards
4042 compatibility feature; in 3.0, all types will use the cache by
4043 default.
4044
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004045- Keyword arguments can now follow starred arguments. (``f(a, *args,
4046 keyword=23)`` is now valid syntax.)
4047
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004048- ctypes function pointers that are COM methods have a boolean True
4049 value again.
4050
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004051- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4052 by denying s# to parse objects that have a releasebuffer procedure,
4053 and introducing s*.
4054
Georg Brandl1e13ea92008-08-11 09:07:59 +00004055- Issue #3537: Fix an assertion failure when an empty but presized dict
4056 object was stored in the freelist.
4057
Mark Dickinsonb6467572008-08-04 21:30:09 +00004058- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4059 ValueError consistently across platforms.
4060
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004061- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4062 (64bit Unix, for example), unichr() would truncate its argument and return
4063 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4064
Neal Norwitze7d8be82008-07-31 17:17:14 +00004065- Apply security patches from Apple.
4066
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004067- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4068 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4069
Antoine Pitrou92f82162008-07-25 22:22:08 +00004070- Issue #1819: function calls with several named parameters are now on
4071 average 35% faster (as measured by pybench).
4072
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004073- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4074 the python debugger steps into a class statement: the free variables (local
4075 variables defined in an outer scope) would be deleted from the outer scope.
4076
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004077- Issue #2620: Overflow checking when allocating or reallocating memory
4078 was not always being done properly in some python types and extension
4079 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4080 all been updated to perform better checks and places in the code that
4081 would previously leak memory on the error path when such an allocation
4082 failed have been fixed.
4083

4085-------
4086
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004087- Issue #3612: Added some missing basic types in ctypes.wintypes.
4088
Benjamin Petersone977ad42008-08-20 01:42:01 +00004089- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4090 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4091
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004092- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4093 version reported by these tools does not necessarily follow the python
4094 version numbering scheme, so the module is less strict when parsing it.
4095
Nick Coghlanf70385a2008-08-18 12:42:46 +00004096- Issue #2235: Added Py3k warnings for types which will become unhashable
4097 under the stricter __hash__ inheritance rules in 3.0. Several types
4098 which did not meet the rules for hash invariants and were already
4099 unhashable in 3.0 have now been explicitly flagged as unhashable in
4100 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4101 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4102
Brett Cannon88f801d2008-08-18 00:46:22 +00004103- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4104 imported into the module but exposed as part of the module's API.
4105
Brett Cannon7b96f072008-08-18 00:41:11 +00004106- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4107

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004110- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4111
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004112- Issue #3575: Incremental decoder's decode function now takes bytearray
4113 by using 's*' instead of 't#'.
4114
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004115- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004116 fails unicode conversion on 2nd parameter. (windows only)
4117
Georg Brandl222e2082010-08-01 22:27:39 +00004118- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004119 in a redirect.
4120
Brett Cannonabe423e2008-08-16 21:47:07 +00004121- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004122 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004123
Facundo Batistaeb90b782008-08-16 14:44:07 +00004124- Issue #2776: fixed small issue when handling an URL with double slash
4125 after a 302 response in the case of not going through a proxy.
4126
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004127- Issue #2676: in the email package, content-type parsing was hanging on
4128 pathological input because of quadratic or exponential behaviour of a
4129 regular expression.
4130
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004131- Issue #3476: binary buffered reading through the new "io" library is now
4132 thread-safe.
4133
Brett Cannonbf3157b2008-08-14 05:00:03 +00004134- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4135 since mimetools itself is deprecated. Because modules are cached, all
4136 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4137
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004138- Issue #3134: shutil referenced undefined WindowsError symbol.
4139
Robert Schuppenies14646332008-08-10 11:01:53 +00004140- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4141 menu entries were not deleted.
4142
Brett Cannon83e81842008-08-09 23:30:55 +00004143- Copied the implementation of reduce() to _functools.reduce() to have a
4144 version that did not raise a DeprecationWarning under -3.
4145
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004146- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4147 a MemoryError rather than silently stop the iteration.
4148
Guido van Rossum59ce9012008-08-09 14:55:34 +00004149- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4150 to _sre.compile() will now be rejected. This should not affect anybody
4151 since the re.compile() function never generates invalid re-bytecode.
4152
Skip Montanaroa032bf42008-08-08 22:52:51 +00004153- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4154 upon first access it can be automatically initialized from the csv file if
4155 it wasn't initialized during instantiation.
4156
Brett Cannon3aa2a492008-08-06 22:28:09 +00004157- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4158 the reload() built-in has been removed.
4159
Brett Cannon7e30b672008-08-04 21:52:25 +00004160- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004161 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00004172 asking for a specific length. This problem only affected files opened
4173 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004174

4199 file name rather than a ZipInfo instance, so files are extracted with
4200 mode 0600 rather than 000 under Unix.
4201
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004202- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4203 argument in python 2.5, this broke code that subclassed Popen to include its
4204 own poll method. Fixed my moving _deadstate to an _internal_poll method.

4218 coverage of the lookup process for special methods. The disclaimers
4219 regarding lack of coverage of new-style classes have also been
4220 removed, since the coverage is now fairly reasonable.

4229-----------------
4230
Georg Brandl3e483f62008-07-16 22:57:41 +00004231- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4232 its methods now allow for items objects that can be converted to
4233 an integer using operator.index().
4234
Mark Dickinson64b7e502008-07-16 09:40:03 +00004235- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4236 produced a ValueError instead of giving the correct float.
4237
Eric Smitha5fa5a22008-07-16 00:11:49 +00004238- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4239 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4240
Mark Dickinson7103aa42008-07-15 19:08:33 +00004241- Issue #3008: the float type has a new instance method 'float.hex'
4242 and a new class method 'float.fromhex' to convert floating-point
4243 numbers to and from hexadecimal strings, respectively.
4244
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004245- Issue #2235: __hash__ is once again inherited by default. To allow
4246 collections.Hashable to remain meaningful in the presence of the

Nick Coghlanb028f502008-07-13 14:52:36 +00004252- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4253 the parent module cannot be found while performing an absolute import.
4254 This means that an incorrectly defined __package__ attribute will
4255 now only prevent relative imports in that module rather than causing
4256 all imports from that module to fail.

Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004270- Issue #3004: Minor change to slice.indices(): the start and stop
4271 arguments are now treated identically, making the behaviour easier
4272 to describe and understand. For example, slice(None, -10,
4273 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4274 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4275 10, -1).

Georg Brandl5cc774e2008-06-11 20:28:06 +00004729 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004730

Georg Brandl3ee81df2008-05-17 18:14:43 +00004791- Issue #1631171: Re-implement the 'warnings' module in C (the
4792 original Python code has been kept as backup). This will allow for
4793 using the 'warning's machinery in such places as the parser where
4794 use of pure Python code is not possible. Both the ``showarning()``
4795 and ``formatwarning()`` gain an optional 'line' argument which is
4796 not called by default for backwards-compatibility reasons. Setting
4797 ``warnings.showwarning()`` to an implementation that lacks support
4798 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004861- Issue #2550: The approach used by client/server code for obtaining
4862 ports to listen on in network-oriented tests has been refined in an
4863 effort to facilitate running multiple instances of the entire
4864 regression test suite in parallel without issue.
4865 test_support.bind_port() has been fixed such that it will always
4866 return a unique port -- which wasn't always the case with the
4867 previous implementation, especially if socket options had been set
4868 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4869 new implementation of bind_port() will actually raise an exception
4870 if it is passed an AF_INET/SOCK_STREAM socket with either the
4871 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4872 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4873 the socket it's been passed. This currently only applies to
4874 Windows. This option prevents any other sockets from binding to the
4875 host/port we've bound to, thus removing the possibility of the
4876 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4877 when a second SOCK_STREAM socket binds and accepts to a host/port
4878 that's already been bound by another socket. The optional preferred
4879 port parameter to bind_port() has been removed. Under no
4880 circumstances should tests be hard coding ports!
4881
4882 test_support.find_unused_port() has also been introduced, which will
4883 pass a temporary socket object to bind_port() in order to obtain an
4884 unused port. The temporary socket object is then closed and
4885 deleted, and the port is returned. This method should only be used
4886 for obtaining an unused port in order to pass to an external program
4887 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4888 a parameter to a server-oriented class that doesn't give you direct
4889 access to the underlying socket used.
4890
4891 Finally, test_support.HOST has been introduced, which should be used
4892 for the host argument of any relevant socket calls (i.e. bind and
4893 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004894
4895 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004896 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004897 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4898 test_asynchat and test_socket_ssl.
4899
Georg Brandl3ee81df2008-05-17 18:14:43 +00004900 It is now possible for multiple instances of the regression test
4901 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005180- Added the future_builtins module, which contains hex() and oct().
5181 These are the PEP 3127 version of these functions, designed to be
5182 compatible with the hex() and oct() builtins from Python 3.0. They
5183 differ slightly in their output formats from the existing, unchanged
5184 Python 2.6 builtins. The expected usage of the future_builtins
5185 module is:
5186 from future_builtins import hex, oct
5187
Eric Smith7ef40bf2008-02-20 23:34:22 +00005188- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5189 exponents for exponents with absolute value < 100. Follows C99
5190 standard. This is a change on Windows, which would use 3 digits.
5191 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5192 so that any alterations it does to the resulting string will be
5193 available in stringlib/formatter.h (for float.__format__).
5194
Eric Smith5a3c1352008-02-19 13:21:56 +00005195- Implemented PEP 3101, Advanced String Formatting. This adds a new
5196 builtin format(); a format() method for str and unicode; a
5197 __format__() method to object, str, unicode, int, long, float, and
5198 datetime; the class string.Formatter; and the C API
5199 PyObject_Format().
5200
Georg Brandl3ee81df2008-05-17 18:14:43 +00005201- Fixed several potential crashes, all caused by specially crafted
5202 __del__ methods exploiting objects in temporarily inconsistent
5203 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005204
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005205- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005206 prevent a possible crash: an Abstract Base Class would try to access
5207 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005212- Clear all free lists during a gc.collect() of the highest generation
5213 in order to allow pymalloc to free more arenas. Python may give back
5214 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005215
Georg Brandl3ee81df2008-05-17 18:14:43 +00005216- Issue #2045: Fix an infinite recursion triggered when printing a
5217 subclass of collections.defaultdict, if its default_factory is set
5218 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005219
Christian Heimesf75dbef2008-02-08 00:11:31 +00005220- Fixed a minor memory leak in dictobject.c. The content of the free
5221 list was not freed on interpreter shutdown.
5222
Georg Brandl21e99f42010-03-07 15:23:59 +00005223- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005224 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005225
Georg Brandl3ee81df2008-05-17 18:14:43 +00005226- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5227 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005228 to compact the internal free lists of pre-allocted ints and floats.
5229
Georg Brandl3ee81df2008-05-17 18:14:43 +00005230- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5231 calls. Python expected the return type int but the fork familie
5232 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005233
Georg Brandl3ee81df2008-05-17 18:14:43 +00005234- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00005243- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5244 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005245
Georg Brandl3ee81df2008-05-17 18:14:43 +00005246- Patch #1473257: generator objects gain a gi_code attribute. This is
5247 the same object as the func_code attribute of the function that
5248 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005249
Georg Brandl3ee81df2008-05-17 18:14:43 +00005250- Issue #1920: "while 0" statements were completely removed by the
5251 compiler, even in the presence of an "else" clause, which is
5252 supposed to be run when the condition is false. Now the compiler
5253 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005254
Guido van Rossumeead05f2008-01-24 18:21:02 +00005255- A few crashers fixed: weakref_in_del.py (issue #1377858);
5256 loosing_dict_ref.py (issue #1303614, test67.py);
5257 borrowed_ref_[34].py (not in tracker).
5258
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005259- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005260 suppressed while an extension is loaded by calling SetErrorMode in
5261 dynload_win.c. The error is still reported properly.
5262
Georg Brandl3ee81df2008-05-17 18:14:43 +00005263- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005264 several extension methods and modules do not work without unicode
5265 support.
5266
Georg Brandl26543b12008-01-21 18:36:51 +00005267- Issue #1882: when compiling code from a string, encoding cookies in the
5268 second line of code were not always recognized correctly.
5269
Georg Brandl14404b62008-01-19 19:27:05 +00005270- Issue #1679: "0x" was taken as a valid integer literal.
5271
Georg Brandl6caad7d2008-01-26 14:19:22 +00005272- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005273 added.
5274
Christian Heimesc94e2b52008-01-14 04:13:37 +00005275- sys.float_info / PyFloat_GetInfo: The floating point information
5276 object was converted from a dict to a specialized structseq object.
5277
Georg Brandl3ee81df2008-05-17 18:14:43 +00005278- Patch #1816: Added sys.flags structseq. It exposes the status of
5279 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005280
Georg Brandl3ee81df2008-05-17 18:14:43 +00005281- Objects/structseq.c: Implemented new structseq representation. The
5282 patch makes structseqs (e.g. the return value of os.stat) more
5283 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005284
Georg Brandl3ee81df2008-05-17 18:14:43 +00005285- Patch #1700288: added a type attribute cache that caches method

5294 envvar and sys.dont_write_bytecode attribute. All these can be set
5295 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005296
Georg Brandl3ee81df2008-05-17 18:14:43 +00005297- Improve some exception messages when Windows fails to load an
5298 extension module. Now we get for example '%1 is not a valid Win32
5299 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005300

Georg Brandl3ee81df2008-05-17 18:14:43 +00005307 and INF. float("nan"), float("inf") and float("-inf") now work on
5308 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005309
Georg Brandl3ee81df2008-05-17 18:14:43 +00005310- Compiler now generates simpler and faster code for dictionary
5311 literals. The oparg for BUILD_MAP now indicates an estimated

Georg Brandl3ee81df2008-05-17 18:14:43 +00005361- Issue #1686386: Tuple's tp_repr did not take into account the
5362 possibility of having a self-referential tuple, which is possible
5363 from C code. Nor did object's tp_str consider that a type's tp_str
5364 could do something that could lead to an inifinite recursion.
5365 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5366 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005382 PyObject_Call() never calling back out to Python code to trigger
5383 recursion depth updates/checks. Required the creation of a static

5433
Guido van Rossum143b5642007-03-23 04:58:42 +00005434- Bug #1683368: The object.__init__() and object.__new__() methods are
5435 now stricter in rejecting excess arguments. The only time when
5436 either allows excess arguments is when it is not overridden and the
5437 other one is. For backwards compatibility, when both are
5438 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005439 warning later). Also, type.__init__() insists on the same signature
5440 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005442- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5443 object to complex using its __complex__() method before falling back
5444 to the __float__() method. Therefore, the functions in the cmath
5445 module now can operate on objects that define a __complex__()
5446 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00005464- Bug #1678647: write a newline after printing an exception in any
5465 case, even when converting the value to a string failed.
5466
Georg Brandl871f1bc2007-03-12 13:17:36 +00005467- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005468 its argument, if it exists. If not, it will work like before. This
5469 allows customizing the output of dir() in the presence of a
5470 __getattr__().

5480 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005481
Georg Brandlaa2321b2007-03-07 00:40:28 +00005482- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005483 makes the filenames the warning module prints much more sensible
5484 when a PYTHONSTARTUP file is used.

5499
Georg Brandl3ee81df2008-05-17 18:14:43 +00005500- When printing an unraisable error, don't print exceptions. before

6068
Georg Brandl92a6bae2007-03-13 17:43:32 +00006069- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006070 are set for invalid interpolation sequences that would lead to

6127 TestCase and TestSuite subclasses (not instances) are no longer
6128 accepted in TestSuite.addTest(). This should cause no

6130 -- the failure just occurred later, with a more cumbersome
6131 exception.

6413 with RFC 3207 and forgets any knowledge obtained from the server not
6414 obtained from the TLS negotiation itself. Patch contributed by Bill
6415 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006416
Georg Brandl3ee81df2008-05-17 18:14:43 +00006417- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006418 that the SMTP.starttls() caller no longer needs to call ehlo()
6419 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006420 does not claim to support starttls. Adds the
6421 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Raymond Hettinger12e94202007-11-07 01:13:09 +00006505

Georg Brandl3ee81df2008-05-17 18:14:43 +00006520 time so that opening a database previously created with the DB_DUP
6521 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6522 opens. Specifically: dictionary assignment to a DB object will
6523 replace all values for a given key when the database allows

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00006804- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00006805 periodic threadstate and signal checking in tight loops. By
6806 default, this option is turned-off. It should only be enabled in
6807 debugged, performance critical applications.

Christian Heimes5b970ad2008-02-06 13:33:44 +00006864
Georg Brandl3ee81df2008-05-17 18:14:43 +00006865- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6866 to ``PyTuple_SetItem``, it can be used to populate a brand new
6867 frozenset; but it does not steal a reference to the added item.

6879
Georg Brandl3ee81df2008-05-17 18:14:43 +00006880- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6881 of w# format code incorrectly truncated the length to an int, even
6882 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6883 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006913- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6914 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006915
Georg Brandl3ee81df2008-05-17 18:14:43 +00006916- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
