33- On darwin, test_site assumed that a framework build was being used, leading
34 to a failure where four directories were expected for site-packages instead
35 of two in a non-framework build.

Mark Dickinsona8d26682010-05-04 16:18:25 +000048- Issue #1533: fix inconsistency in range function argument
49 processing: any non-float non-integer argument is now converted to
50 an integer (if possible) using its __int__ method. Previously, only
51 small arguments were treated this way; larger arguments (those whose
52 __int__ was outside the range of a C long) would produce a TypeError.
53
Nick Coghlanc5e44852010-04-28 14:51:08 +000054- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when

87
Victor Stinnerdb990922010-05-15 21:00:59 +000088- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing
89 error messages when accessing undefined class attributes because of the cheap
90 inheritance with the underlying socket object.
Giampaolo Rodolàf7454fa2010-05-06 17:57:06 +000091 The cheap inheritance has been deprecated.

102 ASCII with backslashreplace error handler if str(value) failed
103
Mark Dickinson4f96f5f2010-05-04 14:25:50 +0000104- Issue #8567: Fix precedence of signals in Decimal module: when a
105 Decimal operation raises multiple signals and more than one of those
106 signals is trapped, the specification determines the order in which
107 the signals should be handled. In many cases this order wasn't
108 being followed, leading to the wrong Python exception being raised.
109
Antoine Pitrouf7fd8e42010-05-03 16:25:33 +0000110- Issue #7865: The close() method of :mod:`io` objects should not swallow

Tarek Ziadéa5cd1822010-04-30 12:15:12 +0000126 between the build dir and the source dir when looking for "python.h" or
127 "Include".

139 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
Nick Coghlan54677da2010-04-28 14:34:30 +0000140 location of the raised exception. Based on initial patch by Lennart
141 Regebro.
Nick Coghlandfb45df2010-04-28 14:29:06 +0000142
Antoine Pitrou4c7bcf12010-04-27 22:03:37 +0000143- Issue #8086: In :func:`ssl.DER_cert_to_PEM_cert()`, fix missing newline

153
Antoine Pitroua6240402010-04-25 21:40:32 +0000154- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
155 where the method could block indefinitely if called just before the
156 event loop started running. This also fixes the occasional freezes
157 witnessed in test_httpservers.
158
Antoine Pitroufc69af12010-04-24 20:04:58 +0000159- Issue #5103: SSL handshake would ignore the socket timeout and block
160 indefinitely if the other end didn't respond.
161
Antoine Pitrou4d3e3722010-04-24 19:57:01 +0000162- The do_handshake() method of SSL objects now adjusts the blocking mode of

Antoine Pitroua5c4b552010-04-22 23:33:02 +0000177- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
178 a non-infinite timeout. Also make that method friendlier with applications
179 wanting to continue using the socket in clear-text mode, by disabling
180 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
181
Antoine Pitrouc715a9e2010-04-21 19:28:03 +0000182- Issue #8484: Load all ciphers and digest algorithms when initializing
183 the _ssl extension, such that verification of some SSL certificates
184 doesn't fail because of an "unknown algorithm".
185

208 filename and date, conforming to the 'standards' they were originally
209 designed to follow. This improves compatibility with patch tools.
210
R. David Murray27ef9372010-04-12 14:26:06 +0000211- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022

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

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

Mark Dickinson8a950712010-04-03 15:47:46 +0000335- Issue #8257: The Decimal construct now accepts a float instance
336 directly, converting that float to a Decimal of equal value:

353 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000354 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
355 are now hashable; Decimal signaling NaNs remain unhashable.

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000477- Issue #8300: When passing a non-integer argument to struct.pack with any
478 integer format code, struct.pack first attempts to convert the non-integer
479 using its __index__ method. If that method is non-existent or raises
480 TypeError it goes on to try the __int__ method, as described below.
481
Georg Brandlba83f822010-03-14 09:50:54 +0000482- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
483 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
484 argument's __int__ method to convert to an integer before packing. It also
485 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
486 was inconsistent: __int__ was used for some integer codes but not for others,
487 and the set of integer codes for which it was used differed between native
488 packing and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +0000786 file position when calling `truncate()`. It would previously change the file

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

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

884Core and Builtins
885-----------------
886
Georg Brandlba83f822010-03-14 09:50:54 +0000887- The ``__complex__()`` method is now looked up on the class of instances to
888 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000890- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
891 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
892
Mark Dickinson1b34d252010-01-01 17:27:30 +0000893- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000894 DeprecationWarning when passed a float argument where an integer was expected.
895 These functions and methods now raise TypeError instead. The majority of the
896 effects of this change are in the extension modules, but some core functions
897 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
898 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000911- Issue #1811: Improve accuracy and cross-platform consistency for true division
912 of integers: the result of a/b is now correctly rounded for ints a and b (at
913 least on IEEE 754 platforms), and in particular does not depend on the
914 internal representation of a long.

922
Georg Brandlba83f822010-03-14 09:50:54 +0000923 These executables now work properly with the arch(1) command: ``arch -ppc
924 python`` will start a universal binary version of python in PPC mode (unlike
925 previous releases).

1072 significant digits instead.

Georg Brandlba83f822010-03-14 09:50:54 +00001081- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1082 decimal string that's guaranteed to round back to x under correct rounding
1083 (with round-half-to-even rounding mode). Previously it gave a string based on
1084 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1085 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1086 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00001088- Issue #7117: On almost all platforms: float-to-string and string-to-float
1089 conversions within Python are now correctly rounded. Places these conversions
1090 occur include: str for floats and complex numbers; the float and complex
1091 constructors; old-style and new-style numeric formatting; serialization and
1092 deserialization of floats and complex numbers using marshal, pickle and json;
1093 parsing of float and imaginary literals in Python code; Decimal-to-float
1094 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001095
Georg Brandlba83f822010-03-14 09:50:54 +00001096 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1097 providing correctly-rounded strtod and dtoa C functions. This code is
1098 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1099 the C compiler. There may be a small number of platforms on which correct
1100 operation of this code cannot be guaranteed, so the code is not used: notably,
1101 this applies to platforms where the C double format is not IEEE 754 binary64,
1102 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1103 and Python's configure script is unable to determine how to change the FPU
1104 precision. On these platforms conversions use the platform strtod and dtoa,
1105 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001107- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1108 uses the correctly-rounded string <-> float conversions described above (when
1109 available), and so produces correctly rounded results that will display nicely
1110 under the float repr. There are two related small changes: (1) round now
1111 accepts any class with an ``__index__()`` method for its second argument (but
1112 no longer accepts floats for the second argument), and (2) an excessively
1113 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1114 raises an exception.

1341 internal representation of integers, for performance reasons. Base 2**30 is
1342 enabled by default on 64-bit machines. Add --enable-big-digits option to

1493 this code path is really executed because I cannot move to such directory on

1529 gives improved memory leak detection when running under Valgrind, while taking
1530 advantage of pymalloc at other times.

2899 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2900 ``printf`` function, whereas PyString_FromFormat has an independent

2924 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2925 when given a tuple of classes as second argument, were looking up
2926 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2927 type object.
2928
Neal Norwitz18aa3882008-08-24 05:04:52 +00002929- Fix crashes on memory allocation failure found with failmalloc.

2998 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2999 for catch_warnings() also led to an improvement in the raising of a
3000 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003066What's New in Python 2.6 beta 3?
3067================================
3068
Barry Warsaw07a4a382008-08-21 01:15:08 +00003069*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003070
3071Core and Builtins
3072-----------------
3073
Guido van Rossumf8402962008-08-20 15:01:50 +00003074- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3075 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3076 extensions do not automatically benefit from the class attribute
3077 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3078 to their tp_flags field if they care. This is a backwards
3079 compatibility feature; in 3.0, all types will use the cache by
3080 default.
3081
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003082- Keyword arguments can now follow starred arguments. (``f(a, *args,
3083 keyword=23)`` is now valid syntax.)
3084
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003085- ctypes function pointers that are COM methods have a boolean True
3086 value again.
3087
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003088- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3089 by denying s# to parse objects that have a releasebuffer procedure,
3090 and introducing s*.
3091
Georg Brandl1e13ea92008-08-11 09:07:59 +00003092- Issue #3537: Fix an assertion failure when an empty but presized dict
3093 object was stored in the freelist.
3094
Mark Dickinsonb6467572008-08-04 21:30:09 +00003095- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3096 ValueError consistently across platforms.
3097
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003098- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3099 (64bit Unix, for example), unichr() would truncate its argument and return
3100 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3101
Neal Norwitze7d8be82008-07-31 17:17:14 +00003102- Apply security patches from Apple.
3103
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003104- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3105 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3106
Antoine Pitrou92f82162008-07-25 22:22:08 +00003107- Issue #1819: function calls with several named parameters are now on
3108 average 35% faster (as measured by pybench).
3109
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003110- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3111 the python debugger steps into a class statement: the free variables (local
3112 variables defined in an outer scope) would be deleted from the outer scope.
3113
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003114- Issue #2620: Overflow checking when allocating or reallocating memory
3115 was not always being done properly in some python types and extension
3116 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3117 all been updated to perform better checks and places in the code that
3118 would previously leak memory on the error path when such an allocation
3119 failed have been fixed.

3123
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003124- Issue #3612: Added some missing basic types in ctypes.wintypes.
3125
Benjamin Petersone977ad42008-08-20 01:42:01 +00003126- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3127 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3128
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003129- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3130 version reported by these tools does not necessarily follow the python
3131 version numbering scheme, so the module is less strict when parsing it.
3132
Nick Coghlanf70385a2008-08-18 12:42:46 +00003133- Issue #2235: Added Py3k warnings for types which will become unhashable
3134 under the stricter __hash__ inheritance rules in 3.0. Several types
3135 which did not meet the rules for hash invariants and were already
3136 unhashable in 3.0 have now been explicitly flagged as unhashable in
3137 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3138 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3139
Brett Cannon88f801d2008-08-18 00:46:22 +00003140- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3141 imported into the module but exposed as part of the module's API.
3142
Brett Cannon7b96f072008-08-18 00:41:11 +00003143- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3144
Brett Cannon46225e72008-08-18 00:36:52 +00003145- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

3148
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003149- Issue #3575: Incremental decoder's decode function now takes bytearray
3150 by using 's*' instead of 't#'.
3151
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003152- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003153 fails unicode conversion on 2nd parameter. (windows only)
3154
Facundo Batista94f243a2008-08-17 03:38:39 +00003155- Issue 2464. urllib2 now supports a malformation in the URL received
3156 in a redirect.
3157
Brett Cannonabe423e2008-08-16 21:47:07 +00003158- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003159 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003160
Facundo Batistaeb90b782008-08-16 14:44:07 +00003161- Issue #2776: fixed small issue when handling an URL with double slash
3162 after a 302 response in the case of not going through a proxy.
3163
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003164- Issue #2676: in the email package, content-type parsing was hanging on
3165 pathological input because of quadratic or exponential behaviour of a
3166 regular expression.
3167
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003168- Issue #3476: binary buffered reading through the new "io" library is now
3169 thread-safe.
3170
Brett Cannonbf3157b2008-08-14 05:00:03 +00003171- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3172 since mimetools itself is deprecated. Because modules are cached, all
3173 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3174
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003175- Issue #3134: shutil referenced undefined WindowsError symbol.
3176
Robert Schuppenies14646332008-08-10 11:01:53 +00003177- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3178 menu entries were not deleted.
3179
Brett Cannon83e81842008-08-09 23:30:55 +00003180- Copied the implementation of reduce() to _functools.reduce() to have a
3181 version that did not raise a DeprecationWarning under -3.
3182
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003183- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3184 a MemoryError rather than silently stop the iteration.
3185
Guido van Rossum59ce9012008-08-09 14:55:34 +00003186- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3187 to _sre.compile() will now be rejected. This should not affect anybody
3188 since the re.compile() function never generates invalid re-bytecode.
3189
Skip Montanaroa032bf42008-08-08 22:52:51 +00003190- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3191 upon first access it can be automatically initialized from the csv file if
3192 it wasn't initialized during instantiation.
3193
Brett Cannon3aa2a492008-08-06 22:28:09 +00003194- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3195 the reload() built-in has been removed.
3196
Brett Cannon7e30b672008-08-04 21:52:25 +00003197- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003198 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00003209 asking for a specific length. This problem only affected files opened
3210 using the new "io" module, not the built-in open() function.

3237 mode 0600 rather than 000 under Unix.
3238
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003239- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

3261================================
3262
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003263*Release date: 17-Jul-2008*

3266-----------------
3267
Georg Brandl3e483f62008-07-16 22:57:41 +00003268- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3269 its methods now allow for items objects that can be converted to
3270 an integer using operator.index().
3271
Mark Dickinson64b7e502008-07-16 09:40:03 +00003272- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3273 produced a ValueError instead of giving the correct float.
3274
Eric Smitha5fa5a22008-07-16 00:11:49 +00003275- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3276 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3277
Mark Dickinson7103aa42008-07-15 19:08:33 +00003278- Issue #3008: the float type has a new instance method 'float.hex'
3279 and a new class method 'float.fromhex' to convert floating-point
3280 numbers to and from hexadecimal strings, respectively.
3281
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003282- Issue #2235: __hash__ is once again inherited by default. To allow
3283 collections.Hashable to remain meaningful in the presence of the
3284 default hash implementation (object.__hash__), it is now possible
3285 to explicit block inheritance of hash by setting __hash__=None at
3286 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3287 level.
3288
Nick Coghlanb028f502008-07-13 14:52:36 +00003289- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3290 the parent module cannot be found while performing an absolute import.
3291 This means that an incorrectly defined __package__ attribute will
3292 now only prevent relative imports in that module rather than causing
3293 all imports from that module to fail.
3294
Nick Coghlan14ff9942008-07-08 14:21:42 +00003295- Issue #2517: Allow unicode messages in Exceptions again by correctly

3304 threading.local: the first member set by a thread could be saved in
3305 another thread's dictionary.
3306
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003307- Issue #3004: Minor change to slice.indices(): the start and stop
3308 arguments are now treated identically, making the behaviour easier
3309 to describe and understand. For example, slice(None, -10,
3310 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3311 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3312 10, -1).
3313
Georg Brandl278fc502008-07-19 12:46:12 +00003314- Issue #3219: Calling a function with repeated keyword arguments,
3315 f(a=2, a=23), would not cause a syntax error. This was a regression
3316 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003317
Georg Brandl278fc502008-07-19 12:46:12 +00003318- Issue #2862: Make int and float freelist management consistent with
3319 other freelists. Changes their CompactFreeList apis into
3320 ClearFreeList apis and calls them via gc.collect().

3326 api functions without holding the GIL, which could lead to a fatal
3327 error when they failed.
3328
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003329- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003354- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3355 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003356 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003357 content-length. The problem had been corrected in the 2.4 branch, but never
3358 merged into trunk.
3359
Georg Brandle78fbcc2008-07-05 10:13:36 +00003360- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003373- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3374 handling is now the same as that of other special attributes like __name__).
3375
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003376- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl74a1dea2008-05-28 11:21:39 +00003784- Add ``PyType_Modified()`` as a public API to clear the type cache.
3785
3786- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00003787
3788- The PyString functions have been renamed to PyBytes. A batch of
3789 defines were added so that the linker still sees the original
3790 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003828- Issue #1631171: Re-implement the 'warnings' module in C (the
3829 original Python code has been kept as backup). This will allow for
3830 using the 'warning's machinery in such places as the parser where
3831 use of pure Python code is not possible. Both the ``showarning()``
3832 and ``formatwarning()`` gain an optional 'line' argument which is
3833 not called by default for backwards-compatibility reasons. Setting
3834 ``warnings.showwarning()`` to an implementation that lacks support
3835 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003860- The getpass module has been improved on Unix. It now uses /dev/tty
3861 by default and uses stderr instead of stdout. A GetPassWarning is
3862 issued when input echo cannot be controlled.

3874 implementation detail of the public ``types`` module, has been
3875 removed and replaced by pure python code.
Amaury Forgeot d'Arc02f33b42008-04-08 23:10:07 +00003876
Georg Brandl3ee81df2008-05-17 18:14:43 +00003877- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003878 extension modules between 32 and 64 bit platforms. See the distutls
3879 build documentation for more information.

3882 threads at once without fear of crashing the Python interpreter. If
3883 file.close() is called while an object is in use by another thread
3884 an IOError exception will be raised and the file will not be closed.
3885
Thomas Hellerf7906482008-04-04 19:43:25 +00003886- The bundled libffi copy is now in sync with the recently released

3891 so the controlled environment will more closely mirror the typical
3892 script environment. This supports setup.py scripts that refer to
3893 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003898- Issue #2550: The approach used by client/server code for obtaining
3899 ports to listen on in network-oriented tests has been refined in an
3900 effort to facilitate running multiple instances of the entire
3901 regression test suite in parallel without issue.
3902 test_support.bind_port() has been fixed such that it will always
3903 return a unique port -- which wasn't always the case with the
3904 previous implementation, especially if socket options had been set
3905 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3906 new implementation of bind_port() will actually raise an exception
3907 if it is passed an AF_INET/SOCK_STREAM socket with either the
3908 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3909 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3910 the socket it's been passed. This currently only applies to
3911 Windows. This option prevents any other sockets from binding to the
3912 host/port we've bound to, thus removing the possibility of the
3913 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3914 when a second SOCK_STREAM socket binds and accepts to a host/port
3915 that's already been bound by another socket. The optional preferred
3916 port parameter to bind_port() has been removed. Under no
3917 circumstances should tests be hard coding ports!
3918
3919 test_support.find_unused_port() has also been introduced, which will
3920 pass a temporary socket object to bind_port() in order to obtain an
3921 unused port. The temporary socket object is then closed and
3922 deleted, and the port is returned. This method should only be used
3923 for obtaining an unused port in order to pass to an external program
3924 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3925 a parameter to a server-oriented class that doesn't give you direct
3926 access to the underlying socket used.
3927
3928 Finally, test_support.HOST has been introduced, which should be used
3929 for the host argument of any relevant socket calls (i.e. bind and
3930 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003931
3932 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003933 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003934 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3935 test_asynchat and test_socket_ssl.
3936
Georg Brandl3ee81df2008-05-17 18:14:43 +00003937 It is now possible for multiple instances of the regression test
3938 suite to run in parallel without issue.

4205-----------------
4206
Fred Drakea8ee94b2008-03-01 02:45:07 +00004207- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004208 644. The mode is now inherited from the py file.

4211
4212- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004213
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004214- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004215 issue 215555 for a discussion.
4216
Eric Smitha73fbe72008-02-23 03:09:44 +00004217- Added the future_builtins module, which contains hex() and oct().
4218 These are the PEP 3127 version of these functions, designed to be
4219 compatible with the hex() and oct() builtins from Python 3.0. They
4220 differ slightly in their output formats from the existing, unchanged
4221 Python 2.6 builtins. The expected usage of the future_builtins
4222 module is:
4223 from future_builtins import hex, oct
4224
Eric Smith7ef40bf2008-02-20 23:34:22 +00004225- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4226 exponents for exponents with absolute value < 100. Follows C99
4227 standard. This is a change on Windows, which would use 3 digits.
4228 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4229 so that any alterations it does to the resulting string will be
4230 available in stringlib/formatter.h (for float.__format__).
4231
Eric Smith5a3c1352008-02-19 13:21:56 +00004232- Implemented PEP 3101, Advanced String Formatting. This adds a new
4233 builtin format(); a format() method for str and unicode; a
4234 __format__() method to object, str, unicode, int, long, float, and
4235 datetime; the class string.Formatter; and the C API
4236 PyObject_Format().
4237
Georg Brandl3ee81df2008-05-17 18:14:43 +00004238- Fixed several potential crashes, all caused by specially crafted
4239 __del__ methods exploiting objects in temporarily inconsistent
4240 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004241
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004242- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004243 prevent a possible crash: an Abstract Base Class would try to access
4244 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004245

Georg Brandl3ee81df2008-05-17 18:14:43 +00004249- Clear all free lists during a gc.collect() of the highest generation
4250 in order to allow pymalloc to free more arenas. Python may give back
4251 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004252
Georg Brandl3ee81df2008-05-17 18:14:43 +00004253- Issue #2045: Fix an infinite recursion triggered when printing a
4254 subclass of collections.defaultdict, if its default_factory is set
4255 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004256
Christian Heimesf75dbef2008-02-08 00:11:31 +00004257- Fixed a minor memory leak in dictobject.c. The content of the free
4258 list was not freed on interpreter shutdown.
4259
Georg Brandl21e99f42010-03-07 15:23:59 +00004260- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004261 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004262
Georg Brandl3ee81df2008-05-17 18:14:43 +00004263- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4264 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004265 to compact the internal free lists of pre-allocted ints and floats.
4266
Georg Brandl3ee81df2008-05-17 18:14:43 +00004267- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4268 calls. Python expected the return type int but the fork familie
4269 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004270

4281 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004282
Georg Brandl3ee81df2008-05-17 18:14:43 +00004283- Patch #1473257: generator objects gain a gi_code attribute. This is
4284 the same object as the func_code attribute of the function that
4285 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004286
Georg Brandl3ee81df2008-05-17 18:14:43 +00004287- Issue #1920: "while 0" statements were completely removed by the
4288 compiler, even in the presence of an "else" clause, which is
4289 supposed to be run when the condition is false. Now the compiler
4290 correctly emits bytecode for the "else" suite.

Guido van Rossumeead05f2008-01-24 18:21:02 +00004292- A few crashers fixed: weakref_in_del.py (issue #1377858);
4293 loosing_dict_ref.py (issue #1303614, test67.py);
4294 borrowed_ref_[34].py (not in tracker).
4295
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004296- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004297 suppressed while an extension is loaded by calling SetErrorMode in
4298 dynload_win.c. The error is still reported properly.
4299
Georg Brandl3ee81df2008-05-17 18:14:43 +00004300- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004301 several extension methods and modules do not work without unicode
4302 support.
4303
Georg Brandl26543b12008-01-21 18:36:51 +00004304- Issue #1882: when compiling code from a string, encoding cookies in the
4305 second line of code were not always recognized correctly.
4306
Georg Brandl14404b62008-01-19 19:27:05 +00004307- Issue #1679: "0x" was taken as a valid integer literal.
4308
Georg Brandl6caad7d2008-01-26 14:19:22 +00004309- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004310 added.
4311
Christian Heimesc94e2b52008-01-14 04:13:37 +00004312- sys.float_info / PyFloat_GetInfo: The floating point information
4313 object was converted from a dict to a specialized structseq object.
4314
Georg Brandl3ee81df2008-05-17 18:14:43 +00004315- Patch #1816: Added sys.flags structseq. It exposes the status of
4316 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004317
Georg Brandl3ee81df2008-05-17 18:14:43 +00004318- Objects/structseq.c: Implemented new structseq representation. The
4319 patch makes structseqs (e.g. the return value of os.stat) more
4320 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004321
Georg Brandl3ee81df2008-05-17 18:14:43 +00004322- Patch #1700288: added a type attribute cache that caches method
4323 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004324
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004325- Bug #1776: __import__() no longer accepts filenames on any platform.
4326 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004327
Georg Brandlaed6c662008-01-07 17:25:53 +00004328- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4329
Georg Brandl3ee81df2008-05-17 18:14:43 +00004330- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4331 envvar and sys.dont_write_bytecode attribute. All these can be set
4332 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004333
Georg Brandl3ee81df2008-05-17 18:14:43 +00004334- Improve some exception messages when Windows fails to load an
4335 extension module. Now we get for example '%1 is not a valid Win32
4336 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004337
Georg Brandl3ee81df2008-05-17 18:14:43 +00004338- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004340- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4341 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004342
Christian Heimes0a8143f2007-12-18 23:22:54 +00004343- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004344 and INF. float("nan"), float("inf") and float("-inf") now work on
4345 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004346
Georg Brandl3ee81df2008-05-17 18:14:43 +00004347- Compiler now generates simpler and faster code for dictionary
4348 literals. The oparg for BUILD_MAP now indicates an estimated
4349 dictionary size. There is a new opcode, STORE_MAP, for adding
4350 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004351
Georg Brandl3ee81df2008-05-17 18:14:43 +00004352- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00004353
Georg Brandl3ee81df2008-05-17 18:14:43 +00004354- Issue #1620: New property decorator syntax was modifying the
4355 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00004356
Georg Brandl3ee81df2008-05-17 18:14:43 +00004357- Issue #1538: Avoid copying string in split/rsplit if the split char
4358 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004359
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004360- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004361 SystemError.
4362
Nick Coghlanef01d822007-12-03 12:55:17 +00004363- PEP 366: Allow explicit relative imports when executing modules
4364 inside packages with the -m switch via a new module level
4365 __package__ attribute.
4366
Georg Brandl3ee81df2008-05-17 18:14:43 +00004367- Issue #1402: Fix a crash on exit, when another thread is still
4368 running, and if the deallocation of its frames somehow calls the
4369 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004370

4372
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00004373- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00004374 attribute of an empty cell object.
4375
Georg Brandl3ee81df2008-05-17 18:14:43 +00004376- Issue #1460: The utf-7 incremental decoder did not accept truncated
4377 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00004378
Georg Brandl3ee81df2008-05-17 18:14:43 +00004379- Patch #1739468: Directories and zipfiles containing a __main__.py
4380 file can now be directly executed by passing their name to the
4381 interpreter. The directory/zipfile is automatically inserted as the
4382 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004383
Georg Brandl3ee81df2008-05-17 18:14:43 +00004384- Issue #1265: Fix a problem with sys.settrace, if the tracing
4385 function uses a generator expression when at the same time the
4386 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004387
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004388- sets and frozensets now have an isdisjoint() method.
4389
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004390- optimize the performance of builtin.sum().
4391
Neal Norwitz44f326e2007-10-05 05:29:17 +00004392- Fix warnings found by the new version of the Coverity checker.
4393
Georg Brandl21e99f42010-03-07 15:23:59 +00004394- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004395 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4396 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004397
Georg Brandl3ee81df2008-05-17 18:14:43 +00004398- Issue #1686386: Tuple's tp_repr did not take into account the
4399 possibility of having a self-referential tuple, which is possible
4400 from C code. Nor did object's tp_str consider that a type's tp_str
4401 could do something that could lead to an inifinite recursion.
4402 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4403 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004404
Georg Brandl3ee81df2008-05-17 18:14:43 +00004405- Issue #1164: It was possible to trigger deadlock when using the
4406 'print' statement to write to a file since the GIL was not released
4407 as needed. Now PyObject_Print() does the right thing along with
4408 various tp_print implementations of the built-in types and those in
4409 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004410
Georg Brandl3ee81df2008-05-17 18:14:43 +00004411- Issue #1147: Exceptions were directly allowing string exceptions in
4412 their throw() method even though string exceptions no longer
4413 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004414
Georg Brandl3ee81df2008-05-17 18:14:43 +00004415- Issue #1096: Prevent a segfault from getting the repr of a very
4416 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004417
Brett Cannon1e534b52007-09-07 04:18:30 +00004418- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004419 PyObject_Call() never calling back out to Python code to trigger
4420 recursion depth updates/checks. Required the creation of a static
4421 RuntimeError instance in case normalizing an exception put the
4422 recursion check value past its limit. Fixes crashers
4423 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004424
Georg Brandl3ee81df2008-05-17 18:14:43 +00004425- Patch #1031213: Decode source line in SyntaxErrors back to its
4426 original source encoding.

Georg Brandl7c3b50d2007-07-12 08:38:00 +00004428- Patch #1673759: add a missing overflow check when formatting floats
4429 with %G.
4430
Georg Brandl3ee81df2008-05-17 18:14:43 +00004431- Prevent expandtabs() on string and unicode objects from causing a
4432 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00004433

Georg Brandla5ea6892007-06-01 11:33:33 +00004437
Neal Norwitz0ac60192007-05-27 04:08:54 +00004438- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004439 __*__ attributes. (Some already existed, e.g., __doc__ and
4440 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004441
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004442- Add -3 option to the interpreter to warn about features that are
4443 deprecated and will be changed/removed in Python 3.0.
4444
Georg Brandl2134e752007-05-21 20:34:16 +00004445- Patch #1686487: you can now pass any mapping after '**' in function
4446 calls.
4447
Collin Winter62903052007-05-18 23:11:24 +00004448- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004449 "except E as target:". This is to provide forwards compatibility
4450 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004451
Brett Cannon229cee22007-05-05 01:34:02 +00004452- Deprecate BaseException.message as per PEP 352.
4453
Georg Brandl3ee81df2008-05-17 18:14:43 +00004454- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004455 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004456
Vinay Sajip8549ce32007-05-06 17:53:37 +00004457- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004458 setting a plain string, ie don't expand to single letter identifiers.
4459
Raymond Hettinger13936692007-04-11 18:40:58 +00004460- Request #1191699: Slices can now be pickled.
4461
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004462- Request #1193128: str.translate() now allows a None argument for
4463 translations that only remove characters without re-mapping the
4464 remaining characters.
4465
Georg Brandl5cb76c12007-03-21 09:00:39 +00004466- Patch #1682205: a TypeError while unpacking an iterable is no longer
4467 masked by a generic one with the message "unpack non-sequence".
4468
Neal Norwitzaa754b72007-03-21 06:39:48 +00004469- Remove unused file Python/fmod.c.
4470
Guido van Rossum143b5642007-03-23 04:58:42 +00004471- Bug #1683368: The object.__init__() and object.__new__() methods are
4472 now stricter in rejecting excess arguments. The only time when
4473 either allows excess arguments is when it is not overridden and the
4474 other one is. For backwards compatibility, when both are
4475 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004476 warning later). Also, type.__init__() insists on the same signature
4477 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004478
Georg Brandl3ee81df2008-05-17 18:14:43 +00004479- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4480 object to complex using its __complex__() method before falling back
4481 to the __float__() method. Therefore, the functions in the cmath
4482 module now can operate on objects that define a __complex__()
4483 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004484
Georg Brandl3ee81df2008-05-17 18:14:43 +00004485- Patch #1623563: allow __class__ assignment for classes with
4486 __slots__. The old and the new class are still required to have the
4487 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004488
Georg Brandl3ee81df2008-05-17 18:14:43 +00004489- Patch #1642547: Fix an error/crash when encountering syntax errors
4490 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004492- Patch #1462488: Python no longer segfaults when
4493 ``object.__reduce_ex__()`` is called with an object that is faking
4494 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004495
Georg Brandl3ee81df2008-05-17 18:14:43 +00004496- Patch #1680015: Don't modify __slots__ tuple if it contains an
4497 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00004499- Patch #1444529: the builtin compile() now accepts keyword arguments.
4500
Georg Brandl7b9c5552007-03-12 14:30:05 +00004501- Bug #1678647: write a newline after printing an exception in any
4502 case, even when converting the value to a string failed.
4503
Georg Brandl871f1bc2007-03-12 13:17:36 +00004504- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004505 its argument, if it exists. If not, it will work like before. This
4506 allows customizing the output of dir() in the presence of a
4507 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004508
Collin Winter276887b2007-03-12 16:11:39 +00004509- Patch #922167: Python no longer segfaults when faced with infinitely
4510 self-recursive reload() calls (as reported by bug #742342).
4511
Georg Brandl3ee81df2008-05-17 18:14:43 +00004512- Patch #1675981: remove unreachable code from ``type.__new__()``
4513 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00004514
Georg Brandl3ee81df2008-05-17 18:14:43 +00004515- Patch #1491866: change the complex() constructor to allow
4516 parthensized forms. This means complex(repr(x)) now works instead of
4517 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004518
Georg Brandlaa2321b2007-03-07 00:40:28 +00004519- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004520 makes the filenames the warning module prints much more sensible
4521 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004522
Georg Brandl49aafc92007-03-07 00:34:46 +00004523- Variant of patch #697613: don't exit the interpreter on a SystemExit
4524 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004525 variable is given, but break into the interactive interpreter just
4526 like on other exceptions or normal program exit.
Georg Brandl49aafc92007-03-07 00:34:46 +00004527
Georg Brandl3ee81df2008-05-17 18:14:43 +00004528- Patch #1638879: don't accept strings with embedded NUL bytes in

Georg Brandlfb4b3b72007-04-24 15:27:13 +00005026- Bug #1706381: Specifying the SWIG option "-c++" in the setup.py file
5027 (as opposed to the command line) will now write file names ending in
5028 ".cpp" too.
5029
Facundo Batistad918a652007-04-24 13:54:38 +00005030- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005031 the client's request was successfully received, understood, and
5032 accepted. Now in these cases no error is raised in urllib (issue
5033 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00005034

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00005041- Added a timeout parameter to the constructor of other protocols
5042 (telnetlib, ftplib, smtplib and poplib). This is second part of the
5043 work started with create_connection() and timeout in httplib, and
5044 closes patch #723312.
5045
Vinay Sajip8549ce32007-05-06 17:53:37 +00005046- Patch #1676823: Added create_connection() to socket.py, which may be
5047 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00005048 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00005049
Martin v. Löwis0af33882007-03-23 13:27:15 +00005050- Bug #978833: Revert r50844, as it broke _socketobject.dup.
5051

Georg Brandl3ee81df2008-05-17 18:14:43 +00005057- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
5058 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00005059 directories.
5060

5070
Georg Brandlf66b6032007-03-14 08:27:52 +00005071- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00005072 AttributeError instead of an IOError when the server's response
5073 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00005074
Georg Brandl3ee81df2008-05-17 18:14:43 +00005075- Patch #957650: "%var%" environment variable references are now
5076 properly expanded in ntpath.expandvars(), also "~user" home
5077 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00005078
Georg Brandl3ee81df2008-05-17 18:14:43 +00005079- Patch #1429539: pdb now correctly initializes the __main__ module
5080 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00005081 correctly now.
5082
Georg Brandlbad6f192007-03-13 21:32:56 +00005083- The nonobvious commands.getstatus() function is now deprecated.

5089
Georg Brandl3ee81df2008-05-17 18:14:43 +00005090- Patch #1530482: add pydoc.render_doc() which returns the
5091 documentation for a thing instead of paging it to stdout, which
5092 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00005093
Georg Brandl3ee81df2008-05-17 18:14:43 +00005094- Patch #1533909: the timeit module now accepts callables in addition

5100 parameter which can be set to False to prevent the default
5101 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00005102
Georg Brandl9e6b4702007-03-13 18:15:41 +00005103- Patch #1581073: add a flag to textwrap that prevents the dropping of
5104 whitespace while wrapping.
5105
Georg Brandl92a6bae2007-03-13 17:43:32 +00005106- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005107 are set for invalid interpolation sequences that would lead to
5108 errors on reading back those values.

5122
Georg Brandl94fe3f52007-03-13 09:32:11 +00005123- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00005124 field names in its exception message if you try to write a record
5125 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00005143

5151 returned string up to the first NUL character.

5162
Georg Brandl3ee81df2008-05-17 18:14:43 +00005163- unittest now verifies more of its assumptions. In particular,
5164 TestCase and TestSuite subclasses (not instances) are no longer
5165 accepted in TestSuite.addTest(). This should cause no
5166 incompatibility since it never made sense with ordinary subclasses
5167 -- the failure just occurred later, with a more cumbersome
5168 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00005169

5177 given a unicode argument and os.listdir() returns unicode filenames.
5178
Georg Brandl3ee81df2008-05-17 18:14:43 +00005179- Patch #1673619: setup.py identifies extension modules it doesn't
5180 know how to build and those it knows how to build but that fail to
5181 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005557 time so that opening a database previously created with the DB_DUP
5558 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5559 opens. Specifically: dictionary assignment to a DB object will
5560 replace all values for a given key when the database allows
5561 duplicate values. DB users should use DB.put(k, v) when they want
5562 to store duplicates; not DB[k] = v.

5569 characters with ASCII value less than 32. Also, it correctly quotes
5570 dots only if they occur on a single line, as opposed to the previous
5571 behavior of quoting dots if they are the second character of any
5572 line.
