Mark Dickinsona8d26682010-05-04 16:18:25 +000046- Issue #1533: fix inconsistency in range function argument
47 processing: any non-float non-integer argument is now converted to
48 an integer (if possible) using its __int__ method. Previously, only
49 small arguments were treated this way; larger arguments (those whose
50 __int__ was outside the range of a C long) would produce a TypeError.
51
Nick Coghlanc5e44852010-04-28 14:51:08 +000052- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when

Victor Stinnerdb990922010-05-15 21:00:59 +000086- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing
87 error messages when accessing undefined class attributes because of the cheap
88 inheritance with the underlying socket object.
Giampaolo Rodolàf7454fa2010-05-06 17:57:06 +000089 The cheap inheritance has been deprecated.

101
Mark Dickinson4f96f5f2010-05-04 14:25:50 +0000102- Issue #8567: Fix precedence of signals in Decimal module: when a
103 Decimal operation raises multiple signals and more than one of those
104 signals is trapped, the specification determines the order in which
105 the signals should be handled. In many cases this order wasn't
106 being followed, leading to the wrong Python exception being raised.
107
Antoine Pitrouf7fd8e42010-05-03 16:25:33 +0000108- Issue #7865: The close() method of :mod:`io` objects should not swallow

Tarek Ziadéa5cd1822010-04-30 12:15:12 +0000124 between the build dir and the source dir when looking for "python.h" or
125 "Include".

137 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
Nick Coghlan54677da2010-04-28 14:34:30 +0000138 location of the raised exception. Based on initial patch by Lennart
139 Regebro.

151
Antoine Pitroua6240402010-04-25 21:40:32 +0000152- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
153 where the method could block indefinitely if called just before the
154 event loop started running. This also fixes the occasional freezes
155 witnessed in test_httpservers.
156
Antoine Pitroufc69af12010-04-24 20:04:58 +0000157- Issue #5103: SSL handshake would ignore the socket timeout and block
158 indefinitely if the other end didn't respond.
159
Antoine Pitrou4d3e3722010-04-24 19:57:01 +0000160- The do_handshake() method of SSL objects now adjusts the blocking mode of

176 a non-infinite timeout. Also make that method friendlier with applications
177 wanting to continue using the socket in clear-text mode, by disabling
178 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
179
Antoine Pitrouc715a9e2010-04-21 19:28:03 +0000180- Issue #8484: Load all ciphers and digest algorithms when initializing
181 the _ssl extension, such that verification of some SSL certificates
182 doesn't fail because of an "unknown algorithm".
183

206 filename and date, conforming to the 'standards' they were originally
207 designed to follow. This improves compatibility with patch tools.
208
R. David Murray27ef9372010-04-12 14:26:06 +0000209- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022

254 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

295 is called with a non-empty format string. This is an effort to
296 future-proof user code. If a derived class does not currently

298 most likely break user code that had supplied a format string. This
299 will be changed to a DeprecationWaring in Python 3.3 and it will be

Mark Dickinson8a950712010-04-03 15:47:46 +0000333- Issue #8257: The Decimal construct now accepts a float instance
334 directly, converting that float to a Decimal of equal value:
335
336 >>> Decimal(1.1)

351 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000352 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000475- Issue #8300: When passing a non-integer argument to struct.pack with any
476 integer format code, struct.pack first attempts to convert the non-integer
477 using its __index__ method. If that method is non-existent or raises
478 TypeError it goes on to try the __int__ method, as described below.
479
Georg Brandlba83f822010-03-14 09:50:54 +0000480- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
481 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
482 argument's __int__ method to convert to an integer before packing. It also
483 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
484 was inconsistent: __int__ was used for some integer codes but not for others,
485 and the set of integer codes for which it was used differed between native
486 packing and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +0000784 file position when calling `truncate()`. It would previously change the file
785 position to the given argument, which goes against the tradition of

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

882Core and Builtins
883-----------------
884
Georg Brandlba83f822010-03-14 09:50:54 +0000885- The ``__complex__()`` method is now looked up on the class of instances to
886 make it consistent with other special methods.

890
Mark Dickinson1b34d252010-01-01 17:27:30 +0000891- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000892 DeprecationWarning when passed a float argument where an integer was expected.
893 These functions and methods now raise TypeError instead. The majority of the
894 effects of this change are in the extension modules, but some core functions
895 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
896 and many unicode/str methods.

910 of integers: the result of a/b is now correctly rounded for ints a and b (at
911 least on IEEE 754 platforms), and in particular does not depend on the
912 internal representation of a long.

920
Georg Brandlba83f822010-03-14 09:50:54 +0000921 These executables now work properly with the arch(1) command: ``arch -ppc
922 python`` will start a universal binary version of python in PPC mode (unlike
923 previous releases).

1070 significant digits instead.

Georg Brandlba83f822010-03-14 09:50:54 +00001079- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1080 decimal string that's guaranteed to round back to x under correct rounding
1081 (with round-half-to-even rounding mode). Previously it gave a string based on
1082 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1083 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1084 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00001086- Issue #7117: On almost all platforms: float-to-string and string-to-float
1087 conversions within Python are now correctly rounded. Places these conversions
1088 occur include: str for floats and complex numbers; the float and complex
1089 constructors; old-style and new-style numeric formatting; serialization and
1090 deserialization of floats and complex numbers using marshal, pickle and json;
1091 parsing of float and imaginary literals in Python code; Decimal-to-float
1092 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001093
Georg Brandlba83f822010-03-14 09:50:54 +00001094 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1095 providing correctly-rounded strtod and dtoa C functions. This code is
1096 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1097 the C compiler. There may be a small number of platforms on which correct
1098 operation of this code cannot be guaranteed, so the code is not used: notably,
1099 this applies to platforms where the C double format is not IEEE 754 binary64,
1100 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1101 and Python's configure script is unable to determine how to change the FPU
1102 precision. On these platforms conversions use the platform strtod and dtoa,
1103 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001105- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1106 uses the correctly-rounded string <-> float conversions described above (when
1107 available), and so produces correctly rounded results that will display nicely
1108 under the float repr. There are two related small changes: (1) round now
1109 accepts any class with an ``__index__()`` method for its second argument (but
1110 no longer accepts floats for the second argument), and (2) an excessively
1111 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1112 raises an exception.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00001329- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00001330 untrackable objects are not tracked by the garbage collector. This can reduce
1331 the size of collections and therefore the garbage collection overhead on
1332 long-running programs, depending on their particular use of datatypes.

1339 internal representation of integers, for performance reasons. Base 2**30 is
1340 enabled by default on 64-bit machines. Add --enable-big-digits option to
1341 configure, which overrides the default. Add sys.long_info structseq to
1342 provide information about the internal format.

Benjamin Petersone18ef192009-01-20 14:21:16 +00001372- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
1373
Georg Brandl29c6a282009-04-05 20:23:13 +00001374- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00001375 were suppressing all exceptions. These include list(), filter(), map(),

1377
Benjamin Peterson596d3062009-01-19 15:42:23 +00001378- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

1404
Georg Brandlba83f822010-03-14 09:50:54 +00001405- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1406 existing .py counterpart, override the co_filename attributes of all code
1407 objects if the original filename is obsolete (which can happen if the file has
1408 been renamed, moved, or if it is accessed through different paths). Patch by

1462
Georg Brandlba83f822010-03-14 09:50:54 +00001463- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1464 file objects with closefd=False. The file descriptor is still kept open but
1465 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00001489- On windows, ``os.chdir()`` given unicode was not working if
1490 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1491 this code path is really executed because I cannot move to such directory on
1492 win2k)

Walter Dörwalded960ac2009-05-03 22:36:33 +00001517- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1518 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1519 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1520 of using the replace error handler in PyUnicode_DecodeUTF8().
1521
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001522- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00002335 for *nix machines for negative handles and large int handles. Without this
2336 check it is possible to segfault the interpreter.

Georg Brandlba83f822010-03-14 09:50:54 +00002355 the timestamp in the gzip stream. The default value remains the current time.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002895- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

2897 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2898 ``printf`` function, whereas PyString_FromFormat has an independent

2922 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2923 when given a tuple of classes as second argument, were looking up
2924 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2925 type object.
2926
Neal Norwitz18aa3882008-08-24 05:04:52 +00002927- Fix crashes on memory allocation failure found with failmalloc.

2996 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2997 for catch_warnings() also led to an improvement in the raising of a
2998 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003064What's New in Python 2.6 beta 3?
3065================================
3066
Barry Warsaw07a4a382008-08-21 01:15:08 +00003067*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003068
3069Core and Builtins
3070-----------------
3071
Guido van Rossumf8402962008-08-20 15:01:50 +00003072- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3073 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3074 extensions do not automatically benefit from the class attribute
3075 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3076 to their tp_flags field if they care. This is a backwards
3077 compatibility feature; in 3.0, all types will use the cache by
3078 default.
3079
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003080- Keyword arguments can now follow starred arguments. (``f(a, *args,
3081 keyword=23)`` is now valid syntax.)
3082
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003083- ctypes function pointers that are COM methods have a boolean True
3084 value again.
3085
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003086- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3087 by denying s# to parse objects that have a releasebuffer procedure,
3088 and introducing s*.
3089
Georg Brandl1e13ea92008-08-11 09:07:59 +00003090- Issue #3537: Fix an assertion failure when an empty but presized dict
3091 object was stored in the freelist.
3092
Mark Dickinsonb6467572008-08-04 21:30:09 +00003093- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3094 ValueError consistently across platforms.
3095
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003096- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3097 (64bit Unix, for example), unichr() would truncate its argument and return
3098 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3099
Neal Norwitze7d8be82008-07-31 17:17:14 +00003100- Apply security patches from Apple.
3101
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003102- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3103 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3104
Antoine Pitrou92f82162008-07-25 22:22:08 +00003105- Issue #1819: function calls with several named parameters are now on
3106 average 35% faster (as measured by pybench).
3107
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003108- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3109 the python debugger steps into a class statement: the free variables (local
3110 variables defined in an outer scope) would be deleted from the outer scope.
3111
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003112- Issue #2620: Overflow checking when allocating or reallocating memory
3113 was not always being done properly in some python types and extension
3114 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3115 all been updated to perform better checks and places in the code that
3116 would previously leak memory on the error path when such an allocation
3117 failed have been fixed.

3121
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003122- Issue #3612: Added some missing basic types in ctypes.wintypes.
3123
Benjamin Petersone977ad42008-08-20 01:42:01 +00003124- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3125 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3126
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003127- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3128 version reported by these tools does not necessarily follow the python
3129 version numbering scheme, so the module is less strict when parsing it.
3130
Nick Coghlanf70385a2008-08-18 12:42:46 +00003131- Issue #2235: Added Py3k warnings for types which will become unhashable
3132 under the stricter __hash__ inheritance rules in 3.0. Several types
3133 which did not meet the rules for hash invariants and were already
3134 unhashable in 3.0 have now been explicitly flagged as unhashable in
3135 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3136 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3137
Brett Cannon88f801d2008-08-18 00:46:22 +00003138- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3139 imported into the module but exposed as part of the module's API.
3140
Brett Cannon7b96f072008-08-18 00:41:11 +00003141- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3142
Brett Cannon46225e72008-08-18 00:36:52 +00003143- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

3146
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003147- Issue #3575: Incremental decoder's decode function now takes bytearray
3148 by using 's*' instead of 't#'.
3149
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003150- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003151 fails unicode conversion on 2nd parameter. (windows only)
3152
Facundo Batista94f243a2008-08-17 03:38:39 +00003153- Issue 2464. urllib2 now supports a malformation in the URL received
3154 in a redirect.
3155
Brett Cannonabe423e2008-08-16 21:47:07 +00003156- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003157 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003158
Facundo Batistaeb90b782008-08-16 14:44:07 +00003159- Issue #2776: fixed small issue when handling an URL with double slash
3160 after a 302 response in the case of not going through a proxy.
3161
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003162- Issue #2676: in the email package, content-type parsing was hanging on
3163 pathological input because of quadratic or exponential behaviour of a
3164 regular expression.
3165
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003166- Issue #3476: binary buffered reading through the new "io" library is now
3167 thread-safe.
3168
Brett Cannonbf3157b2008-08-14 05:00:03 +00003169- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3170 since mimetools itself is deprecated. Because modules are cached, all
3171 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3172
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003173- Issue #3134: shutil referenced undefined WindowsError symbol.
3174
Robert Schuppenies14646332008-08-10 11:01:53 +00003175- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3176 menu entries were not deleted.
3177
Brett Cannon83e81842008-08-09 23:30:55 +00003178- Copied the implementation of reduce() to _functools.reduce() to have a
3179 version that did not raise a DeprecationWarning under -3.
3180
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003181- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3182 a MemoryError rather than silently stop the iteration.
3183
Guido van Rossum59ce9012008-08-09 14:55:34 +00003184- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3185 to _sre.compile() will now be rejected. This should not affect anybody
3186 since the re.compile() function never generates invalid re-bytecode.
3187
Skip Montanaroa032bf42008-08-08 22:52:51 +00003188- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3189 upon first access it can be automatically initialized from the csv file if
3190 it wasn't initialized during instantiation.
3191
Brett Cannon3aa2a492008-08-06 22:28:09 +00003192- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3193 the reload() built-in has been removed.
3194
Brett Cannon7e30b672008-08-04 21:52:25 +00003195- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003196 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00003207 asking for a specific length. This problem only affected files opened

3264-----------------
3265
Georg Brandl3e483f62008-07-16 22:57:41 +00003266- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3267 its methods now allow for items objects that can be converted to
3268 an integer using operator.index().
3269
Mark Dickinson64b7e502008-07-16 09:40:03 +00003270- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3271 produced a ValueError instead of giving the correct float.
3272
Eric Smitha5fa5a22008-07-16 00:11:49 +00003273- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3274 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3275
Mark Dickinson7103aa42008-07-15 19:08:33 +00003276- Issue #3008: the float type has a new instance method 'float.hex'
3277 and a new class method 'float.fromhex' to convert floating-point
3278 numbers to and from hexadecimal strings, respectively.
3279
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003280- Issue #2235: __hash__ is once again inherited by default. To allow
3281 collections.Hashable to remain meaningful in the presence of the
3282 default hash implementation (object.__hash__), it is now possible
3283 to explicit block inheritance of hash by setting __hash__=None at
3284 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3285 level.
3286
Nick Coghlanb028f502008-07-13 14:52:36 +00003287- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3288 the parent module cannot be found while performing an absolute import.
3289 This means that an incorrectly defined __package__ attribute will
3290 now only prevent relative imports in that module rather than causing
3291 all imports from that module to fail.
3292
Nick Coghlan14ff9942008-07-08 14:21:42 +00003293- Issue #2517: Allow unicode messages in Exceptions again by correctly

3302 threading.local: the first member set by a thread could be saved in
3303 another thread's dictionary.
3304
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003305- Issue #3004: Minor change to slice.indices(): the start and stop
3306 arguments are now treated identically, making the behaviour easier
3307 to describe and understand. For example, slice(None, -10,
3308 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3309 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3310 10, -1).
3311
Georg Brandl278fc502008-07-19 12:46:12 +00003312- Issue #3219: Calling a function with repeated keyword arguments,
3313 f(a=2, a=23), would not cause a syntax error. This was a regression
3314 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003315
Georg Brandl278fc502008-07-19 12:46:12 +00003316- Issue #2862: Make int and float freelist management consistent with
3317 other freelists. Changes their CompactFreeList apis into
3318 ClearFreeList apis and calls them via gc.collect().

3324 api functions without holding the GIL, which could lead to a fatal
3325 error when they failed.
3326
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003327- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003352- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3353 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003354 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003355 content-length. The problem had been corrected in the 2.4 branch, but never
3356 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003371- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3372 handling is now the same as that of other special attributes like __name__).
3373
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003374- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

3784- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00003785
3786- The PyString functions have been renamed to PyBytes. A batch of
3787 defines were added so that the linker still sees the original
3788 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003826- Issue #1631171: Re-implement the 'warnings' module in C (the
3827 original Python code has been kept as backup). This will allow for
3828 using the 'warning's machinery in such places as the parser where
3829 use of pure Python code is not possible. Both the ``showarning()``
3830 and ``formatwarning()`` gain an optional 'line' argument which is
3831 not called by default for backwards-compatibility reasons. Setting
3832 ``warnings.showwarning()`` to an implementation that lacks support
3833 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003858- The getpass module has been improved on Unix. It now uses /dev/tty
3859 by default and uses stderr instead of stdout. A GetPassWarning is
3860 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003875- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003876 extension modules between 32 and 64 bit platforms. See the distutls

3880 threads at once without fear of crashing the Python interpreter. If
3881 file.close() is called while an object is in use by another thread
3882 an IOError exception will be raised and the file will not be closed.
3883
Thomas Hellerf7906482008-04-04 19:43:25 +00003884- The bundled libffi copy is now in sync with the recently released

3889 so the controlled environment will more closely mirror the typical
3890 script environment. This supports setup.py scripts that refer to
3891 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003896- Issue #2550: The approach used by client/server code for obtaining
3897 ports to listen on in network-oriented tests has been refined in an
3898 effort to facilitate running multiple instances of the entire
3899 regression test suite in parallel without issue.
3900 test_support.bind_port() has been fixed such that it will always
3901 return a unique port -- which wasn't always the case with the
3902 previous implementation, especially if socket options had been set
3903 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3904 new implementation of bind_port() will actually raise an exception
3905 if it is passed an AF_INET/SOCK_STREAM socket with either the
3906 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3907 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3908 the socket it's been passed. This currently only applies to
3909 Windows. This option prevents any other sockets from binding to the
3910 host/port we've bound to, thus removing the possibility of the
3911 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3912 when a second SOCK_STREAM socket binds and accepts to a host/port
3913 that's already been bound by another socket. The optional preferred
3914 port parameter to bind_port() has been removed. Under no
3915 circumstances should tests be hard coding ports!
3916
3917 test_support.find_unused_port() has also been introduced, which will
3918 pass a temporary socket object to bind_port() in order to obtain an
3919 unused port. The temporary socket object is then closed and
3920 deleted, and the port is returned. This method should only be used
3921 for obtaining an unused port in order to pass to an external program
3922 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3923 a parameter to a server-oriented class that doesn't give you direct
3924 access to the underlying socket used.
3925
3926 Finally, test_support.HOST has been introduced, which should be used
3927 for the host argument of any relevant socket calls (i.e. bind and
3928 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003929
3930 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003931 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003932 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3933 test_asynchat and test_socket_ssl.
3934
Georg Brandl3ee81df2008-05-17 18:14:43 +00003935 It is now possible for multiple instances of the regression test
3936 suite to run in parallel without issue.

4203-----------------
4204
Fred Drakea8ee94b2008-03-01 02:45:07 +00004205- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004206 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00004211
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004212- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004213 issue 215555 for a discussion.
4214
Eric Smitha73fbe72008-02-23 03:09:44 +00004215- Added the future_builtins module, which contains hex() and oct().
4216 These are the PEP 3127 version of these functions, designed to be
4217 compatible with the hex() and oct() builtins from Python 3.0. They
4218 differ slightly in their output formats from the existing, unchanged
4219 Python 2.6 builtins. The expected usage of the future_builtins
4220 module is:
4221 from future_builtins import hex, oct
4222
Eric Smith7ef40bf2008-02-20 23:34:22 +00004223- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4224 exponents for exponents with absolute value < 100. Follows C99
4225 standard. This is a change on Windows, which would use 3 digits.
4226 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4227 so that any alterations it does to the resulting string will be
4228 available in stringlib/formatter.h (for float.__format__).
4229
Eric Smith5a3c1352008-02-19 13:21:56 +00004230- Implemented PEP 3101, Advanced String Formatting. This adds a new
4231 builtin format(); a format() method for str and unicode; a
4232 __format__() method to object, str, unicode, int, long, float, and
4233 datetime; the class string.Formatter; and the C API
4234 PyObject_Format().
4235
Georg Brandl3ee81df2008-05-17 18:14:43 +00004236- Fixed several potential crashes, all caused by specially crafted
4237 __del__ methods exploiting objects in temporarily inconsistent
4238 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004239
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004240- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004241 prevent a possible crash: an Abstract Base Class would try to access
4242 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004243

Georg Brandl3ee81df2008-05-17 18:14:43 +00004247- Clear all free lists during a gc.collect() of the highest generation
4248 in order to allow pymalloc to free more arenas. Python may give back
4249 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004250
Georg Brandl3ee81df2008-05-17 18:14:43 +00004251- Issue #2045: Fix an infinite recursion triggered when printing a
4252 subclass of collections.defaultdict, if its default_factory is set
4253 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004254
Christian Heimesf75dbef2008-02-08 00:11:31 +00004255- Fixed a minor memory leak in dictobject.c. The content of the free
4256 list was not freed on interpreter shutdown.
4257
Georg Brandl21e99f42010-03-07 15:23:59 +00004258- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004259 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004260
Georg Brandl3ee81df2008-05-17 18:14:43 +00004261- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4262 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004263 to compact the internal free lists of pre-allocted ints and floats.
4264
Georg Brandl3ee81df2008-05-17 18:14:43 +00004265- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4266 calls. Python expected the return type int but the fork familie
4267 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004268

Georg Brandl3ee81df2008-05-17 18:14:43 +00004281- Patch #1473257: generator objects gain a gi_code attribute. This is
4282 the same object as the func_code attribute of the function that
4283 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004284
Georg Brandl3ee81df2008-05-17 18:14:43 +00004285- Issue #1920: "while 0" statements were completely removed by the
4286 compiler, even in the presence of an "else" clause, which is
4287 supposed to be run when the condition is false. Now the compiler
4288 correctly emits bytecode for the "else" suite.

Guido van Rossumeead05f2008-01-24 18:21:02 +00004290- A few crashers fixed: weakref_in_del.py (issue #1377858);
4291 loosing_dict_ref.py (issue #1303614, test67.py);
4292 borrowed_ref_[34].py (not in tracker).
4293
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004294- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004295 suppressed while an extension is loaded by calling SetErrorMode in
4296 dynload_win.c. The error is still reported properly.
4297
Georg Brandl3ee81df2008-05-17 18:14:43 +00004298- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004299 several extension methods and modules do not work without unicode
4300 support.
4301
Georg Brandl26543b12008-01-21 18:36:51 +00004302- Issue #1882: when compiling code from a string, encoding cookies in the
4303 second line of code were not always recognized correctly.
4304
Georg Brandl14404b62008-01-19 19:27:05 +00004305- Issue #1679: "0x" was taken as a valid integer literal.
4306
Georg Brandl6caad7d2008-01-26 14:19:22 +00004307- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004308 added.
4309
Christian Heimesc94e2b52008-01-14 04:13:37 +00004310- sys.float_info / PyFloat_GetInfo: The floating point information
4311 object was converted from a dict to a specialized structseq object.
4312
Georg Brandl3ee81df2008-05-17 18:14:43 +00004313- Patch #1816: Added sys.flags structseq. It exposes the status of
4314 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004315
Georg Brandl3ee81df2008-05-17 18:14:43 +00004316- Objects/structseq.c: Implemented new structseq representation. The
4317 patch makes structseqs (e.g. the return value of os.stat) more
4318 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004319
Georg Brandl3ee81df2008-05-17 18:14:43 +00004320- Patch #1700288: added a type attribute cache that caches method
4321 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004322
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004323- Bug #1776: __import__() no longer accepts filenames on any platform.
4324 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004325
Georg Brandlaed6c662008-01-07 17:25:53 +00004326- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4327
Georg Brandl3ee81df2008-05-17 18:14:43 +00004328- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4329 envvar and sys.dont_write_bytecode attribute. All these can be set
4330 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004331
Georg Brandl3ee81df2008-05-17 18:14:43 +00004332- Improve some exception messages when Windows fails to load an
4333 extension module. Now we get for example '%1 is not a valid Win32
4334 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004335
Georg Brandl3ee81df2008-05-17 18:14:43 +00004336- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004338- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4339 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004340
Christian Heimes0a8143f2007-12-18 23:22:54 +00004341- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004342 and INF. float("nan"), float("inf") and float("-inf") now work on
4343 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004344
Georg Brandl3ee81df2008-05-17 18:14:43 +00004345- Compiler now generates simpler and faster code for dictionary
4346 literals. The oparg for BUILD_MAP now indicates an estimated
4347 dictionary size. There is a new opcode, STORE_MAP, for adding
4348 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004349
Georg Brandl3ee81df2008-05-17 18:14:43 +00004350- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00004351
Georg Brandl3ee81df2008-05-17 18:14:43 +00004352- Issue #1620: New property decorator syntax was modifying the
4353 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00004354
Georg Brandl3ee81df2008-05-17 18:14:43 +00004355- Issue #1538: Avoid copying string in split/rsplit if the split char
4356 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004357
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004358- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004359 SystemError.
4360
Nick Coghlanef01d822007-12-03 12:55:17 +00004361- PEP 366: Allow explicit relative imports when executing modules
4362 inside packages with the -m switch via a new module level
4363 __package__ attribute.
4364
Georg Brandl3ee81df2008-05-17 18:14:43 +00004365- Issue #1402: Fix a crash on exit, when another thread is still
4366 running, and if the deallocation of its frames somehow calls the
4367 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004368

4370
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00004371- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00004372 attribute of an empty cell object.
4373
Georg Brandl3ee81df2008-05-17 18:14:43 +00004374- Issue #1460: The utf-7 incremental decoder did not accept truncated
4375 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00004376
Georg Brandl3ee81df2008-05-17 18:14:43 +00004377- Patch #1739468: Directories and zipfiles containing a __main__.py
4378 file can now be directly executed by passing their name to the
4379 interpreter. The directory/zipfile is automatically inserted as the
4380 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004381
Georg Brandl3ee81df2008-05-17 18:14:43 +00004382- Issue #1265: Fix a problem with sys.settrace, if the tracing
4383 function uses a generator expression when at the same time the
4384 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004385
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004386- sets and frozensets now have an isdisjoint() method.
4387
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004388- optimize the performance of builtin.sum().
4389
Neal Norwitz44f326e2007-10-05 05:29:17 +00004390- Fix warnings found by the new version of the Coverity checker.
4391
Georg Brandl21e99f42010-03-07 15:23:59 +00004392- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004393 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4394 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004395
Georg Brandl3ee81df2008-05-17 18:14:43 +00004396- Issue #1686386: Tuple's tp_repr did not take into account the
4397 possibility of having a self-referential tuple, which is possible
4398 from C code. Nor did object's tp_str consider that a type's tp_str
4399 could do something that could lead to an inifinite recursion.
4400 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4401 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004402
Georg Brandl3ee81df2008-05-17 18:14:43 +00004403- Issue #1164: It was possible to trigger deadlock when using the
4404 'print' statement to write to a file since the GIL was not released
4405 as needed. Now PyObject_Print() does the right thing along with
4406 various tp_print implementations of the built-in types and those in
4407 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004408
Georg Brandl3ee81df2008-05-17 18:14:43 +00004409- Issue #1147: Exceptions were directly allowing string exceptions in
4410 their throw() method even though string exceptions no longer
4411 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004412
Georg Brandl3ee81df2008-05-17 18:14:43 +00004413- Issue #1096: Prevent a segfault from getting the repr of a very
4414 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004415
Brett Cannon1e534b52007-09-07 04:18:30 +00004416- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004417 PyObject_Call() never calling back out to Python code to trigger
4418 recursion depth updates/checks. Required the creation of a static
4419 RuntimeError instance in case normalizing an exception put the
4420 recursion check value past its limit. Fixes crashers
4421 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004422
Georg Brandl3ee81df2008-05-17 18:14:43 +00004423- Patch #1031213: Decode source line in SyntaxErrors back to its
4424 original source encoding.

Georg Brandl7c3b50d2007-07-12 08:38:00 +00004426- Patch #1673759: add a missing overflow check when formatting floats
4427 with %G.
4428
Georg Brandl3ee81df2008-05-17 18:14:43 +00004429- Prevent expandtabs() on string and unicode objects from causing a
4430 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00004431

Georg Brandla5ea6892007-06-01 11:33:33 +00004435
Neal Norwitz0ac60192007-05-27 04:08:54 +00004436- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004437 __*__ attributes. (Some already existed, e.g., __doc__ and
4438 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004439
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004440- Add -3 option to the interpreter to warn about features that are
4441 deprecated and will be changed/removed in Python 3.0.
4442
Georg Brandl2134e752007-05-21 20:34:16 +00004443- Patch #1686487: you can now pass any mapping after '**' in function
4444 calls.
4445
Collin Winter62903052007-05-18 23:11:24 +00004446- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004447 "except E as target:". This is to provide forwards compatibility
4448 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004449
Brett Cannon229cee22007-05-05 01:34:02 +00004450- Deprecate BaseException.message as per PEP 352.
4451
Georg Brandl3ee81df2008-05-17 18:14:43 +00004452- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004453 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004454
Vinay Sajip8549ce32007-05-06 17:53:37 +00004455- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004456 setting a plain string, ie don't expand to single letter identifiers.
4457
Raymond Hettinger13936692007-04-11 18:40:58 +00004458- Request #1191699: Slices can now be pickled.
4459
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004460- Request #1193128: str.translate() now allows a None argument for
4461 translations that only remove characters without re-mapping the
4462 remaining characters.
4463
Georg Brandl5cb76c12007-03-21 09:00:39 +00004464- Patch #1682205: a TypeError while unpacking an iterable is no longer
4465 masked by a generic one with the message "unpack non-sequence".
4466
Neal Norwitzaa754b72007-03-21 06:39:48 +00004467- Remove unused file Python/fmod.c.
4468
Guido van Rossum143b5642007-03-23 04:58:42 +00004469- Bug #1683368: The object.__init__() and object.__new__() methods are
4470 now stricter in rejecting excess arguments. The only time when
4471 either allows excess arguments is when it is not overridden and the
4472 other one is. For backwards compatibility, when both are
4473 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004474 warning later). Also, type.__init__() insists on the same signature
4475 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004476
Georg Brandl3ee81df2008-05-17 18:14:43 +00004477- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4478 object to complex using its __complex__() method before falling back
4479 to the __float__() method. Therefore, the functions in the cmath
4480 module now can operate on objects that define a __complex__()
4481 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004482
Georg Brandl3ee81df2008-05-17 18:14:43 +00004483- Patch #1623563: allow __class__ assignment for classes with
4484 __slots__. The old and the new class are still required to have the
4485 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004486
Georg Brandl3ee81df2008-05-17 18:14:43 +00004487- Patch #1642547: Fix an error/crash when encountering syntax errors
4488 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004490- Patch #1462488: Python no longer segfaults when
4491 ``object.__reduce_ex__()`` is called with an object that is faking
4492 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004493
Georg Brandl3ee81df2008-05-17 18:14:43 +00004494- Patch #1680015: Don't modify __slots__ tuple if it contains an
4495 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00004497- Patch #1444529: the builtin compile() now accepts keyword arguments.
4498
Georg Brandl7b9c5552007-03-12 14:30:05 +00004499- Bug #1678647: write a newline after printing an exception in any
4500 case, even when converting the value to a string failed.
4501
Georg Brandl871f1bc2007-03-12 13:17:36 +00004502- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004503 its argument, if it exists. If not, it will work like before. This
4504 allows customizing the output of dir() in the presence of a
4505 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004506
Collin Winter276887b2007-03-12 16:11:39 +00004507- Patch #922167: Python no longer segfaults when faced with infinitely
4508 self-recursive reload() calls (as reported by bug #742342).
4509
Georg Brandl3ee81df2008-05-17 18:14:43 +00004510- Patch #1675981: remove unreachable code from ``type.__new__()``
4511 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00004512
Georg Brandl3ee81df2008-05-17 18:14:43 +00004513- Patch #1491866: change the complex() constructor to allow
4514 parthensized forms. This means complex(repr(x)) now works instead of
4515 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004516
Georg Brandlaa2321b2007-03-07 00:40:28 +00004517- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004518 makes the filenames the warning module prints much more sensible
4519 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004520
Georg Brandl49aafc92007-03-07 00:34:46 +00004521- Variant of patch #697613: don't exit the interpreter on a SystemExit
4522 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004523 variable is given, but break into the interactive interpreter just
4524 like on other exceptions or normal program exit.
Georg Brandl49aafc92007-03-07 00:34:46 +00004525
Georg Brandl3ee81df2008-05-17 18:14:43 +00004526- Patch #1638879: don't accept strings with embedded NUL bytes in

Georg Brandlfb4b3b72007-04-24 15:27:13 +00005024- Bug #1706381: Specifying the SWIG option "-c++" in the setup.py file
5025 (as opposed to the command line) will now write file names ending in
5026 ".cpp" too.
5027
Facundo Batistad918a652007-04-24 13:54:38 +00005028- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005029 the client's request was successfully received, understood, and
5030 accepted. Now in these cases no error is raised in urllib (issue
5031 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00005032

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00005039- Added a timeout parameter to the constructor of other protocols
5040 (telnetlib, ftplib, smtplib and poplib). This is second part of the
5041 work started with create_connection() and timeout in httplib, and
5042 closes patch #723312.
5043
Vinay Sajip8549ce32007-05-06 17:53:37 +00005044- Patch #1676823: Added create_connection() to socket.py, which may be
5045 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00005046 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00005047
Martin v. Löwis0af33882007-03-23 13:27:15 +00005048- Bug #978833: Revert r50844, as it broke _socketobject.dup.
5049

Georg Brandl3ee81df2008-05-17 18:14:43 +00005055- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
5056 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00005057 directories.
5058

5068
Georg Brandlf66b6032007-03-14 08:27:52 +00005069- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00005070 AttributeError instead of an IOError when the server's response
5071 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00005072
Georg Brandl3ee81df2008-05-17 18:14:43 +00005073- Patch #957650: "%var%" environment variable references are now
5074 properly expanded in ntpath.expandvars(), also "~user" home
5075 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00005076
Georg Brandl3ee81df2008-05-17 18:14:43 +00005077- Patch #1429539: pdb now correctly initializes the __main__ module
5078 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00005079 correctly now.
5080
Georg Brandlbad6f192007-03-13 21:32:56 +00005081- The nonobvious commands.getstatus() function is now deprecated.

5087
Georg Brandl3ee81df2008-05-17 18:14:43 +00005088- Patch #1530482: add pydoc.render_doc() which returns the
5089 documentation for a thing instead of paging it to stdout, which
5090 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00005091
Georg Brandl3ee81df2008-05-17 18:14:43 +00005092- Patch #1533909: the timeit module now accepts callables in addition

5098 parameter which can be set to False to prevent the default
5099 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00005100
Georg Brandl9e6b4702007-03-13 18:15:41 +00005101- Patch #1581073: add a flag to textwrap that prevents the dropping of
5102 whitespace while wrapping.
5103
Georg Brandl92a6bae2007-03-13 17:43:32 +00005104- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005105 are set for invalid interpolation sequences that would lead to
5106 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00005107

5120
Georg Brandl94fe3f52007-03-13 09:32:11 +00005121- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00005122 field names in its exception message if you try to write a record
5123 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00005141

5149 returned string up to the first NUL character.

5160
Georg Brandl3ee81df2008-05-17 18:14:43 +00005161- unittest now verifies more of its assumptions. In particular,
5162 TestCase and TestSuite subclasses (not instances) are no longer
5163 accepted in TestSuite.addTest(). This should cause no
5164 incompatibility since it never made sense with ordinary subclasses
5165 -- the failure just occurred later, with a more cumbersome
5166 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00005167

5175 given a unicode argument and os.listdir() returns unicode filenames.
5176
Georg Brandl3ee81df2008-05-17 18:14:43 +00005177- Patch #1673619: setup.py identifies extension modules it doesn't
5178 know how to build and those it knows how to build but that fail to
5179 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005555 time so that opening a database previously created with the DB_DUP
5556 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5557 opens. Specifically: dictionary assignment to a DB object will
5558 replace all values for a given key when the database allows
5559 duplicate values. DB users should use DB.put(k, v) when they want
5560 to store duplicates; not DB[k] = v.

5567 characters with ASCII value less than 32. Also, it correctly quotes
5568 dots only if they occur on a single line, as opposed to the previous
5569 behavior of quoting dots if they are the second character of any
5570 line.
