16
Mark Dickinsona8d26682010-05-04 16:18:25 +000017- Issue #1533: fix inconsistency in range function argument
18 processing: any non-float non-integer argument is now converted to
19 an integer (if possible) using its __int__ method. Previously, only
20 small arguments were treated this way; larger arguments (those whose
21 __int__ was outside the range of a C long) would produce a TypeError.
22
Nick Coghlanc5e44852010-04-28 14:51:08 +000023- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when
24 searching for the module file to be executed with the -m command
25 line option

30 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
31 benefit compared to the dynamic memory allocation fallback. Patch by
32 Charles-François Natali.
33
Benjamin Peterson821a8ea2010-04-16 22:35:38 +000034- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is

64 ASCII with backslashreplace error handler if str(value) failed
65
Mark Dickinson4f96f5f2010-05-04 14:25:50 +000066- Issue #8567: Fix precedence of signals in Decimal module: when a
67 Decimal operation raises multiple signals and more than one of those
68 signals is trapped, the specification determines the order in which
69 the signals should be handled. In many cases this order wasn't
70 being followed, leading to the wrong Python exception being raised.
71
Antoine Pitrouf7fd8e42010-05-03 16:25:33 +000072- Issue #7865: The close() method of :mod:`io` objects should not swallow

98 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
Nick Coghlan54677da2010-04-28 14:34:30 +000099 location of the raised exception. Based on initial patch by Lennart
100 Regebro.

115 event loop started running. This also fixes the occasional freezes
116 witnessed in test_httpservers.
117
Antoine Pitroufc69af12010-04-24 20:04:58 +0000118- Issue #5103: SSL handshake would ignore the socket timeout and block

120
Antoine Pitrou4d3e3722010-04-24 19:57:01 +0000121- The do_handshake() method of SSL objects now adjusts the blocking mode of
122 the SSL structure if necessary (as other methods already do).
123

Antoine Pitroudfb299b2010-04-23 22:54:59 +0000129- Issue #7943: Fix circular reference created when instantiating an SSL
130 socket. Initial patch by Péter Szabó.
131
Sean Reifscheiderf6ce3cb2010-04-23 08:31:55 +0000132- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
133 the string "python" as the *ident*. openlog() arguments are all optional
134 and keywords.
135
Antoine Pitroua5c4b552010-04-22 23:33:02 +0000136- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
137 a non-infinite timeout. Also make that method friendlier with applications
138 wanting to continue using the socket in clear-text mode, by disabling
139 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
140
Antoine Pitrouc715a9e2010-04-21 19:28:03 +0000141- Issue #8484: Load all ciphers and digest algorithms when initializing

235 changed.
236
Mark Dickinson82791672010-04-06 16:47:55 +0000237- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
238 on 64-bit machines. The shift count for either left or right shift is

248 is called with a non-empty format string. This is an effort to
249 future-proof user code. If a derived class does not currently
250 implement __format__ but later adds its own __format__, it would
251 most likely break user code that had supplied a format string. This
252 will be changed to a DeprecationWaring in Python 3.3 and it will be
253 an error in Python 3.4.

281 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
282 and `ssl.OPENSSL_VERSION_NUMBER`.

309 instances now return a result based on the numeric values of the
310 operands; previously they returned an arbitrary result based on
311 the relative ordering of id(float) and id(Decimal).

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

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000428- Issue #8300: When passing a non-integer argument to struct.pack with any
429 integer format code, struct.pack first attempts to convert the non-integer
430 using its __index__ method. If that method is non-existent or raises
431 TypeError it goes on to try the __int__ method, as described below.
432
Georg Brandlba83f822010-03-14 09:50:54 +0000433- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
434 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
435 argument's __int__ method to convert to an integer before packing. It also
436 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
437 was inconsistent: __int__ was used for some integer codes but not for others,
438 and the set of integer codes for which it was used differed between native
439 packing and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +0000737 file position when calling `truncate()`. It would previously change the file
738 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000739 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

744 class used to represent files stored inside an archive. The new
745 implementation is significantly faster and can be wrapped in a
746 ``io.BufferedReader`` object for more speedups. It also solves an issue
747 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000830What's New in Python 2.7 alpha 2?
831=================================

835Core and Builtins
836-----------------
837
Georg Brandlba83f822010-03-14 09:50:54 +0000838- The ``__complex__()`` method is now looked up on the class of instances to
839 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000840
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000841- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
842 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
843
Mark Dickinson1b34d252010-01-01 17:27:30 +0000844- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000845 DeprecationWarning when passed a float argument where an integer was expected.
846 These functions and methods now raise TypeError instead. The majority of the
847 effects of this change are in the extension modules, but some core functions
848 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
849 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +0000850

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000859- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
860 used to drop the time part of the result.
861
Georg Brandlba83f822010-03-14 09:50:54 +0000862- Issue #1811: Improve accuracy and cross-platform consistency for true division
863 of integers: the result of a/b is now correctly rounded for ints a and b (at
864 least on IEEE 754 platforms), and in particular does not depend on the
865 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +0000866
Georg Brandlba83f822010-03-14 09:50:54 +0000867- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
868 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
869 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +0000870
Georg Brandlba83f822010-03-14 09:50:54 +0000871- Issue #6834: Replace the implementation for the 'python' and 'pythonw'
Ronald Oussoren92919a62009-12-24 13:30:58 +0000872 executables on OSX.
873
Georg Brandlba83f822010-03-14 09:50:54 +0000874 These executables now work properly with the arch(1) command: ``arch -ppc
875 python`` will start a universal binary version of python in PPC mode (unlike
876 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +0000877
Georg Brandlba83f822010-03-14 09:50:54 +0000878- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
879 underlying error when the coercion fails for the left hand operand.

Georg Brandlba83f822010-03-14 09:50:54 +0000890- Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``,
891 allowing for a maximum number of tasks within the pool to be completed by the
892 worker before that worker is terminated, and a new one created to replace it.

Benjamin Petersonddd392c2009-12-13 19:19:07 +0000935- Issue #7349: Make methods of file objects in the io module accept None as an
936 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
937 the same as passing no argument.
938
Georg Brandlba83f822010-03-14 09:50:54 +0000939- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

Mark Dickinsona36507c2010-01-30 10:08:33 +0000960
Georg Brandlba83f822010-03-14 09:50:54 +0000961- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
962 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
963 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
964 float arguments for integer format codes (other than 'L'): previously an

1016 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001017
Georg Brandlba83f822010-03-14 09:50:54 +00001018- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1019 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001020

Georg Brandlba83f822010-03-14 09:50:54 +00001032- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1033 decimal string that's guaranteed to round back to x under correct rounding
1034 (with round-half-to-even rounding mode). Previously it gave a string based on
1035 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1036 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1037 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001038
Georg Brandlba83f822010-03-14 09:50:54 +00001039- Issue #7117: On almost all platforms: float-to-string and string-to-float
1040 conversions within Python are now correctly rounded. Places these conversions
1041 occur include: str for floats and complex numbers; the float and complex
1042 constructors; old-style and new-style numeric formatting; serialization and
1043 deserialization of floats and complex numbers using marshal, pickle and json;
1044 parsing of float and imaginary literals in Python code; Decimal-to-float
1045 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001046
Georg Brandlba83f822010-03-14 09:50:54 +00001047 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1048 providing correctly-rounded strtod and dtoa C functions. This code is
1049 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1050 the C compiler. There may be a small number of platforms on which correct
1051 operation of this code cannot be guaranteed, so the code is not used: notably,
1052 this applies to platforms where the C double format is not IEEE 754 binary64,
1053 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1054 and Python's configure script is unable to determine how to change the FPU
1055 precision. On these platforms conversions use the platform strtod and dtoa,
1056 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001057
Georg Brandlba83f822010-03-14 09:50:54 +00001058- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1059 uses the correctly-rounded string <-> float conversions described above (when
1060 available), and so produces correctly rounded results that will display nicely
1061 under the float repr. There are two related small changes: (1) round now
1062 accepts any class with an ``__index__()`` method for its second argument (but
1063 no longer accepts floats for the second argument), and (2) an excessively
1064 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1065 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001283 untrackable objects are not tracked by the garbage collector. This can reduce
1284 the size of collections and therefore the garbage collection overhead on
1285 long-running programs, depending on their particular use of datatypes.

Georg Brandlba83f822010-03-14 09:50:54 +00001291- Issue #4258: Make it possible to use base 2**30 instead of base 2**15 for the
1292 internal representation of integers, for performance reasons. Base 2**30 is
1293 enabled by default on 64-bit machines. Add --enable-big-digits option to
1294 configure, which overrides the default. Add sys.long_info structseq to
1295 provide information about the internal format.

Georg Brandl29c6a282009-04-05 20:23:13 +00001327- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00001328 were suppressing all exceptions. These include list(), filter(), map(),

Georg Brandlba83f822010-03-14 09:50:54 +00001358- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1359 existing .py counterpart, override the co_filename attributes of all code
1360 objects if the original filename is obsolete (which can happen if the file has

1415
Georg Brandlba83f822010-03-14 09:50:54 +00001416- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1417 file objects with closefd=False. The file descriptor is still kept open but
1418 the file object behaves like a closed file. The ``FileIO`` object also got a
1419 new readonly attribute ``closefd``.

1438
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001439- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00001442- On windows, ``os.chdir()`` given unicode was not working if
1443 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1444 this code path is really executed because I cannot move to such directory on
1445 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001447- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1448 element is temporarily replaced with an equivalent frozenset. But the
1449 eventual KeyError would always report the empty ``frozenset()`` as the missing
1450 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00001470- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1471 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1472 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1473 of using the replace error handler in PyUnicode_DecodeUTF8().
1474
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001475- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00001478- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002848- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2849 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2850 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2851 ``printf`` function, whereas PyString_FromFormat has an independent
2852 implementation and uses "%zd" on all platforms for size_t values.
2853 This makes a difference on win64, where ``printf`` needs "%Id" to display
2854 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00002874 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2875 mechanism. In the process, fix a bug where isinstance() and issubclass(),

2877 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2878 type object.

2949 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2950 for catch_warnings() also led to an improvement in the raising of a
2951 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003017What's New in Python 2.6 beta 3?
3018================================
3019
Barry Warsaw07a4a382008-08-21 01:15:08 +00003020*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003021
3022Core and Builtins
3023-----------------
3024
Guido van Rossumf8402962008-08-20 15:01:50 +00003025- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3026 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3027 extensions do not automatically benefit from the class attribute
3028 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3029 to their tp_flags field if they care. This is a backwards
3030 compatibility feature; in 3.0, all types will use the cache by
3031 default.
3032
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003033- Keyword arguments can now follow starred arguments. (``f(a, *args,
3034 keyword=23)`` is now valid syntax.)
3035
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003036- ctypes function pointers that are COM methods have a boolean True
3037 value again.
3038
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003039- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3040 by denying s# to parse objects that have a releasebuffer procedure,
3041 and introducing s*.
3042
Georg Brandl1e13ea92008-08-11 09:07:59 +00003043- Issue #3537: Fix an assertion failure when an empty but presized dict
3044 object was stored in the freelist.
3045
Mark Dickinsonb6467572008-08-04 21:30:09 +00003046- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3047 ValueError consistently across platforms.
3048
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003049- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3050 (64bit Unix, for example), unichr() would truncate its argument and return
3051 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3052
Neal Norwitze7d8be82008-07-31 17:17:14 +00003053- Apply security patches from Apple.
3054
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003055- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3056 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3057
Antoine Pitrou92f82162008-07-25 22:22:08 +00003058- Issue #1819: function calls with several named parameters are now on
3059 average 35% faster (as measured by pybench).
3060
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003061- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3062 the python debugger steps into a class statement: the free variables (local
3063 variables defined in an outer scope) would be deleted from the outer scope.
3064
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003065- Issue #2620: Overflow checking when allocating or reallocating memory
3066 was not always being done properly in some python types and extension
3067 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3068 all been updated to perform better checks and places in the code that
3069 would previously leak memory on the error path when such an allocation
3070 failed have been fixed.
3071
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003072Library
3073-------
3074
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003075- Issue #3612: Added some missing basic types in ctypes.wintypes.
3076
Benjamin Petersone977ad42008-08-20 01:42:01 +00003077- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3078 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3079
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003080- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3081 version reported by these tools does not necessarily follow the python
3082 version numbering scheme, so the module is less strict when parsing it.
3083
Nick Coghlanf70385a2008-08-18 12:42:46 +00003084- Issue #2235: Added Py3k warnings for types which will become unhashable
3085 under the stricter __hash__ inheritance rules in 3.0. Several types
3086 which did not meet the rules for hash invariants and were already
3087 unhashable in 3.0 have now been explicitly flagged as unhashable in
3088 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3089 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3090
Brett Cannon88f801d2008-08-18 00:46:22 +00003091- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

3099
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003100- Issue #3575: Incremental decoder's decode function now takes bytearray
3101 by using 's*' instead of 't#'.
3102
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003103- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003104 fails unicode conversion on 2nd parameter. (windows only)
3105
Facundo Batista94f243a2008-08-17 03:38:39 +00003106- Issue 2464. urllib2 now supports a malformation in the URL received
3107 in a redirect.
3108
Brett Cannonabe423e2008-08-16 21:47:07 +00003109- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003110 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003111
Facundo Batistaeb90b782008-08-16 14:44:07 +00003112- Issue #2776: fixed small issue when handling an URL with double slash
3113 after a 302 response in the case of not going through a proxy.
3114
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003115- Issue #2676: in the email package, content-type parsing was hanging on
3116 pathological input because of quadratic or exponential behaviour of a
3117 regular expression.
3118
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003119- Issue #3476: binary buffered reading through the new "io" library is now
3120 thread-safe.
3121
Brett Cannonbf3157b2008-08-14 05:00:03 +00003122- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3123 since mimetools itself is deprecated. Because modules are cached, all
3124 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3125
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003126- Issue #3134: shutil referenced undefined WindowsError symbol.
3127
Robert Schuppenies14646332008-08-10 11:01:53 +00003128- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3129 menu entries were not deleted.
3130
Brett Cannon83e81842008-08-09 23:30:55 +00003131- Copied the implementation of reduce() to _functools.reduce() to have a
3132 version that did not raise a DeprecationWarning under -3.
3133
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003134- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3135 a MemoryError rather than silently stop the iteration.
3136
Guido van Rossum59ce9012008-08-09 14:55:34 +00003137- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3138 to _sre.compile() will now be rejected. This should not affect anybody
3139 since the re.compile() function never generates invalid re-bytecode.
3140
Skip Montanaroa032bf42008-08-08 22:52:51 +00003141- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Brett Cannon3aa2a492008-08-06 22:28:09 +00003145- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3146 the reload() built-in has been removed.
3147
Brett Cannon7e30b672008-08-04 21:52:25 +00003148- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003149 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00003160 asking for a specific length. This problem only affected files opened
3161 using the new "io" module, not the built-in open() function.

Mark Dickinson64b7e502008-07-16 09:40:03 +00003223- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3224 produced a ValueError instead of giving the correct float.
3225
Eric Smitha5fa5a22008-07-16 00:11:49 +00003226- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3227 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3228
Mark Dickinson7103aa42008-07-15 19:08:33 +00003229- Issue #3008: the float type has a new instance method 'float.hex'
3230 and a new class method 'float.fromhex' to convert floating-point
3231 numbers to and from hexadecimal strings, respectively.
3232
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003233- Issue #2235: __hash__ is once again inherited by default. To allow
3234 collections.Hashable to remain meaningful in the presence of the
3235 default hash implementation (object.__hash__), it is now possible
3236 to explicit block inheritance of hash by setting __hash__=None at
3237 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3238 level.
3239
Nick Coghlanb028f502008-07-13 14:52:36 +00003240- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3241 the parent module cannot be found while performing an absolute import.
3242 This means that an incorrectly defined __package__ attribute will
3243 now only prevent relative imports in that module rather than causing
3244 all imports from that module to fail.
3245
Nick Coghlan14ff9942008-07-08 14:21:42 +00003246- Issue #2517: Allow unicode messages in Exceptions again by correctly

3256 another thread's dictionary.
3257
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003258- Issue #3004: Minor change to slice.indices(): the start and stop
3259 arguments are now treated identically, making the behaviour easier
3260 to describe and understand. For example, slice(None, -10,
3261 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3262 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3263 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00003265- Issue #3219: Calling a function with repeated keyword arguments,
3266 f(a=2, a=23), would not cause a syntax error. This was a regression
3267 from 2.4 caused by the switch to the new compiler.

3306 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003307 wrong because the actual transmitted size could differ from the

Georg Brandl3ee81df2008-05-17 18:14:43 +00003779- Issue #1631171: Re-implement the 'warnings' module in C (the
3780 original Python code has been kept as backup). This will allow for
3781 using the 'warning's machinery in such places as the parser where
3782 use of pure Python code is not possible. Both the ``showarning()``
3783 and ``formatwarning()`` gain an optional 'line' argument which is
3784 not called by default for backwards-compatibility reasons. Setting
3785 ``warnings.showwarning()`` to an implementation that lacks support
3786 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003849- Issue #2550: The approach used by client/server code for obtaining
3850 ports to listen on in network-oriented tests has been refined in an
3851 effort to facilitate running multiple instances of the entire
3852 regression test suite in parallel without issue.
3853 test_support.bind_port() has been fixed such that it will always
3854 return a unique port -- which wasn't always the case with the
3855 previous implementation, especially if socket options had been set
3856 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3857 new implementation of bind_port() will actually raise an exception
3858 if it is passed an AF_INET/SOCK_STREAM socket with either the
3859 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3860 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3861 the socket it's been passed. This currently only applies to
3862 Windows. This option prevents any other sockets from binding to the
3863 host/port we've bound to, thus removing the possibility of the
3864 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3865 when a second SOCK_STREAM socket binds and accepts to a host/port
3866 that's already been bound by another socket. The optional preferred
3867 port parameter to bind_port() has been removed. Under no
3868 circumstances should tests be hard coding ports!
3869
3870 test_support.find_unused_port() has also been introduced, which will
3871 pass a temporary socket object to bind_port() in order to obtain an
3872 unused port. The temporary socket object is then closed and
3873 deleted, and the port is returned. This method should only be used
3874 for obtaining an unused port in order to pass to an external program
3875 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3876 a parameter to a server-oriented class that doesn't give you direct
3877 access to the underlying socket used.
3878
3879 Finally, test_support.HOST has been introduced, which should be used
3880 for the host argument of any relevant socket calls (i.e. bind and
3881 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003882
3883 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003884 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003885 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3886 test_asynchat and test_socket_ssl.
3887
Georg Brandl3ee81df2008-05-17 18:14:43 +00003888 It is now possible for multiple instances of the regression test
3889 suite to run in parallel without issue.

4157
Fred Drakea8ee94b2008-03-01 02:45:07 +00004158- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004159 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00004161- Issue #2067: file.__exit__() now calls subclasses' close() method.
4162
4163- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004164
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004165- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004166 issue 215555 for a discussion.
4167
Eric Smitha73fbe72008-02-23 03:09:44 +00004168- Added the future_builtins module, which contains hex() and oct().
4169 These are the PEP 3127 version of these functions, designed to be
4170 compatible with the hex() and oct() builtins from Python 3.0. They
4171 differ slightly in their output formats from the existing, unchanged
4172 Python 2.6 builtins. The expected usage of the future_builtins
4173 module is:
4174 from future_builtins import hex, oct
4175
Eric Smith7ef40bf2008-02-20 23:34:22 +00004176- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4177 exponents for exponents with absolute value < 100. Follows C99
4178 standard. This is a change on Windows, which would use 3 digits.
4179 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4180 so that any alterations it does to the resulting string will be
4181 available in stringlib/formatter.h (for float.__format__).
4182
Eric Smith5a3c1352008-02-19 13:21:56 +00004183- Implemented PEP 3101, Advanced String Formatting. This adds a new
4184 builtin format(); a format() method for str and unicode; a
4185 __format__() method to object, str, unicode, int, long, float, and
4186 datetime; the class string.Formatter; and the C API
4187 PyObject_Format().
4188
Georg Brandl3ee81df2008-05-17 18:14:43 +00004189- Fixed several potential crashes, all caused by specially crafted
4190 __del__ methods exploiting objects in temporarily inconsistent
4191 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004192
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004193- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004194 prevent a possible crash: an Abstract Base Class would try to access
4195 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004196
Georg Brandl3ee81df2008-05-17 18:14:43 +00004197- Fixed repr() and str() of complex numbers with infinity or nan as
4198 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004199
Georg Brandl3ee81df2008-05-17 18:14:43 +00004200- Clear all free lists during a gc.collect() of the highest generation
4201 in order to allow pymalloc to free more arenas. Python may give back
4202 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004203
Georg Brandl3ee81df2008-05-17 18:14:43 +00004204- Issue #2045: Fix an infinite recursion triggered when printing a
4205 subclass of collections.defaultdict, if its default_factory is set
4206 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004207
Christian Heimesf75dbef2008-02-08 00:11:31 +00004208- Fixed a minor memory leak in dictobject.c. The content of the free
4209 list was not freed on interpreter shutdown.
4210
Georg Brandl21e99f42010-03-07 15:23:59 +00004211- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004212 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004213
Georg Brandl3ee81df2008-05-17 18:14:43 +00004214- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4215 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004216 to compact the internal free lists of pre-allocted ints and floats.
4217
Georg Brandl3ee81df2008-05-17 18:14:43 +00004218- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4219 calls. Python expected the return type int but the fork familie
4220 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004221
Georg Brandl3ee81df2008-05-17 18:14:43 +00004222- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4223 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004224
Georg Brandl3ee81df2008-05-17 18:14:43 +00004225- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4226 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004227

Georg Brandl3ee81df2008-05-17 18:14:43 +00004231- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4232 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004233
Georg Brandl3ee81df2008-05-17 18:14:43 +00004234- Patch #1473257: generator objects gain a gi_code attribute. This is
4235 the same object as the func_code attribute of the function that
4236 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004237
Georg Brandl3ee81df2008-05-17 18:14:43 +00004238- Issue #1920: "while 0" statements were completely removed by the
4239 compiler, even in the presence of an "else" clause, which is
4240 supposed to be run when the condition is false. Now the compiler
4241 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004242
Guido van Rossumeead05f2008-01-24 18:21:02 +00004243- A few crashers fixed: weakref_in_del.py (issue #1377858);
4244 loosing_dict_ref.py (issue #1303614, test67.py);
4245 borrowed_ref_[34].py (not in tracker).
4246
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004247- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004248 suppressed while an extension is loaded by calling SetErrorMode in
4249 dynload_win.c. The error is still reported properly.
4250
Georg Brandl3ee81df2008-05-17 18:14:43 +00004251- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004252 several extension methods and modules do not work without unicode
4253 support.
4254
Georg Brandl26543b12008-01-21 18:36:51 +00004255- Issue #1882: when compiling code from a string, encoding cookies in the
4256 second line of code were not always recognized correctly.
4257
Georg Brandl14404b62008-01-19 19:27:05 +00004258- Issue #1679: "0x" was taken as a valid integer literal.
4259
Georg Brandl6caad7d2008-01-26 14:19:22 +00004260- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004261 added.
4262
Christian Heimesc94e2b52008-01-14 04:13:37 +00004263- sys.float_info / PyFloat_GetInfo: The floating point information
4264 object was converted from a dict to a specialized structseq object.
4265
Georg Brandl3ee81df2008-05-17 18:14:43 +00004266- Patch #1816: Added sys.flags structseq. It exposes the status of
4267 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004268
Georg Brandl3ee81df2008-05-17 18:14:43 +00004269- Objects/structseq.c: Implemented new structseq representation. The
4270 patch makes structseqs (e.g. the return value of os.stat) more
4271 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004272
Georg Brandl3ee81df2008-05-17 18:14:43 +00004273- Patch #1700288: added a type attribute cache that caches method
4274 accesses, resulting in speedups in heavily object-oriented code.

4282 envvar and sys.dont_write_bytecode attribute. All these can be set
4283 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004284
Georg Brandl3ee81df2008-05-17 18:14:43 +00004285- Improve some exception messages when Windows fails to load an
4286 extension module. Now we get for example '%1 is not a valid Win32
4287 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004288

Georg Brandl3ee81df2008-05-17 18:14:43 +00004295 and INF. float("nan"), float("inf") and float("-inf") now work on
4296 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004298- Compiler now generates simpler and faster code for dictionary
4299 literals. The oparg for BUILD_MAP now indicates an estimated
4300 dictionary size. There is a new opcode, STORE_MAP, for adding
4301 entries to the dictionary.

4331 file can now be directly executed by passing their name to the
4332 interpreter. The directory/zipfile is automatically inserted as the
4333 first entry in sys.path.

4344
Georg Brandl21e99f42010-03-07 15:23:59 +00004345- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004346 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4347 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004348
Georg Brandl3ee81df2008-05-17 18:14:43 +00004349- Issue #1686386: Tuple's tp_repr did not take into account the
4350 possibility of having a self-referential tuple, which is possible
4351 from C code. Nor did object's tp_str consider that a type's tp_str
4352 could do something that could lead to an inifinite recursion.
4353 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4354 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004355
Georg Brandl3ee81df2008-05-17 18:14:43 +00004356- Issue #1164: It was possible to trigger deadlock when using the
4357 'print' statement to write to a file since the GIL was not released
4358 as needed. Now PyObject_Print() does the right thing along with
4359 various tp_print implementations of the built-in types and those in
4360 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00004369- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004370 PyObject_Call() never calling back out to Python code to trigger
4371 recursion depth updates/checks. Required the creation of a static
4372 RuntimeError instance in case normalizing an exception put the
4373 recursion check value past its limit. Fixes crashers
4374 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00004389- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004390 __*__ attributes. (Some already existed, e.g., __doc__ and
4391 __name__.)

4397 calls.
4398
Collin Winter62903052007-05-18 23:11:24 +00004399- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004400 "except E as target:". This is to provide forwards compatibility
4401 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004408- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004409 setting a plain string, ie don't expand to single letter identifiers.
4410
Raymond Hettinger13936692007-04-11 18:40:58 +00004411- Request #1191699: Slices can now be pickled.
4412
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004413- Request #1193128: str.translate() now allows a None argument for
4414 translations that only remove characters without re-mapping the
4415 remaining characters.
4416
Georg Brandl5cb76c12007-03-21 09:00:39 +00004417- Patch #1682205: a TypeError while unpacking an iterable is no longer

4421
Guido van Rossum143b5642007-03-23 04:58:42 +00004422- Bug #1683368: The object.__init__() and object.__new__() methods are
4423 now stricter in rejecting excess arguments. The only time when
4424 either allows excess arguments is when it is not overridden and the
4425 other one is. For backwards compatibility, when both are
4426 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004427 warning later). Also, type.__init__() insists on the same signature
4428 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004429
Georg Brandl3ee81df2008-05-17 18:14:43 +00004430- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4431 object to complex using its __complex__() method before falling back
4432 to the __float__() method. Therefore, the functions in the cmath
4433 module now can operate on objects that define a __complex__()
4434 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004436- Patch #1623563: allow __class__ assignment for classes with
4437 __slots__. The old and the new class are still required to have the
4438 same slot names.

4445 its type.

4451
Georg Brandl7b9c5552007-03-12 14:30:05 +00004452- Bug #1678647: write a newline after printing an exception in any
4453 case, even when converting the value to a string failed.
4454
Georg Brandl871f1bc2007-03-12 13:17:36 +00004455- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004456 its argument, if it exists. If not, it will work like before. This
4457 allows customizing the output of dir() in the presence of a
4458 __getattr__().

4462
Georg Brandl3ee81df2008-05-17 18:14:43 +00004463- Patch #1675981: remove unreachable code from ``type.__new__()``

4467 parthensized forms. This means complex(repr(x)) now works instead of
4468 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004469
Georg Brandlaa2321b2007-03-07 00:40:28 +00004470- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004471 makes the filenames the warning module prints much more sensible
4472 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004485- Patch #1674228: when assigning a slice (old-style), check for the
4486 sq_ass_slice instead of the sq_slice slot.
4487
Georg Brandl3ee81df2008-05-17 18:14:43 +00004488- When printing an unraisable error, don't print exceptions. before
4489 the name. This duplicates the behavior whening normally printing
4490 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005041- Patch #1530482: add pydoc.render_doc() which returns the

Georg Brandl3ee81df2008-05-17 18:14:43 +00005058 are set for invalid interpolation sequences that would lead to

5115 TestCase and TestSuite subclasses (not instances) are no longer
5116 accepted in TestSuite.addTest(). This should cause no
5117 incompatibility since it never made sense with ordinary subclasses
5118 -- the failure just occurred later, with a more cumbersome
5119 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005406 that the SMTP.starttls() caller no longer needs to call ehlo()

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005507- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00005508 time so that opening a database previously created with the DB_DUP
5509 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5510 opens. Specifically: dictionary assignment to a DB object will
5511 replace all values for a given key when the database allows
5512 duplicate values. DB users should use DB.put(k, v) when they want
5513 to store duplicates; not DB[k] = v.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005793 periodic threadstate and signal checking in tight loops. By
5794 default, this option is turned-off. It should only be enabled in

5869 of w# format code incorrectly truncated the length to an int, even
5870 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5871 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005901- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5902 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
