Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000122- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
123 start byte and the continuation byte(s) are now considered invalid, instead
124 of the number of bytes specified by the start byte.
125 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
126 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
127 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
128 Previous versions returned a single u'\ufffd'.

Mark Dickinson23f0d6b2010-06-05 11:52:24 +0000130- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +0000131 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
132 arises from the "Overriding __eq__ blocks inheritance ..." warning
133 when turned into an exception: in this case the exception simply
134 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +0000135
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000136- Issue #8748: Fix two issues with comparisons between complex and integer
137 objects. (1) The comparison could incorrectly return True in some cases
138 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
139 (2) The comparison raised an OverflowError for large integers, leading
140 to unpredictable exceptions when combining integers and complex objects
141 in sets or dicts.
142
Mark Dickinson81336372010-05-30 12:12:25 +0000143- Issue #5211: Implicit coercion for the complex type is now completely
144 removed. (Coercion for arithmetic operations was already removed in 2.7
145 alpha 4, but coercion for rich comparisons was accidentally left in.)
146
Victor Stinnerc49dfcc2010-05-25 22:30:32 +0000147- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

Georg Brandlba83f822010-03-14 09:50:54 +00001011 file position when calling `truncate()`. It would previously change the file
1012 position to the given argument, which goes against the tradition of

1016 class used to represent files stored inside an archive. The new
1017 implementation is significantly faster and can be wrapped in a

1019 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00001030- Issue #7748: Since unicode values are supported for some metadata options in
1031 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1032 encoded string for them. This ensures that the upload and register commands
1033 send the correct values to PyPI without any error.

1108-----------------
1109
Georg Brandlba83f822010-03-14 09:50:54 +00001110- The ``__complex__()`` method is now looked up on the class of instances to
1111 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001113- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,

1115
Mark Dickinson1b34d252010-01-01 17:27:30 +00001116- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001117 DeprecationWarning when passed a float argument where an integer was expected.
1118 These functions and methods now raise TypeError instead. The majority of the
1119 effects of this change are in the extension modules, but some core functions
1120 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1121 and many unicode/str methods.

1135 of integers: the result of a/b is now correctly rounded for ints a and b (at
1136 least on IEEE 754 platforms), and in particular does not depend on the
1137 internal representation of a long.

1145
Georg Brandlba83f822010-03-14 09:50:54 +00001146 These executables now work properly with the arch(1) command: ``arch -ppc
1147 python`` will start a universal binary version of python in PPC mode (unlike
1148 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00001283- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
1284 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001285
Georg Brandlba83f822010-03-14 09:50:54 +00001286- Issue #3382: 'F' formatting for float and complex now convert the result to
1287 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1288 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001289
Georg Brandlba83f822010-03-14 09:50:54 +00001290- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1291 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001292
Georg Brandlba83f822010-03-14 09:50:54 +00001293- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1294 1e-100 used to raise OverflowError, but now gives the requested 120
1295 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00001296
Georg Brandlba83f822010-03-14 09:50:54 +00001297- Add Py3k warnings for parameter names in parentheses.

Benjamin Peterson89b1a5c2009-11-19 22:58:01 +00001300
Georg Brandlba83f822010-03-14 09:50:54 +00001301- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
1302 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001303
Georg Brandlba83f822010-03-14 09:50:54 +00001304- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1305 decimal string that's guaranteed to round back to x under correct rounding
1306 (with round-half-to-even rounding mode). Previously it gave a string based on
1307 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1308 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1309 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001310
Georg Brandlba83f822010-03-14 09:50:54 +00001311- Issue #7117: On almost all platforms: float-to-string and string-to-float
1312 conversions within Python are now correctly rounded. Places these conversions
1313 occur include: str for floats and complex numbers; the float and complex
1314 constructors; old-style and new-style numeric formatting; serialization and
1315 deserialization of floats and complex numbers using marshal, pickle and json;
1316 parsing of float and imaginary literals in Python code; Decimal-to-float
1317 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001318
Georg Brandlba83f822010-03-14 09:50:54 +00001319 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1320 providing correctly-rounded strtod and dtoa C functions. This code is
1321 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1322 the C compiler. There may be a small number of platforms on which correct
1323 operation of this code cannot be guaranteed, so the code is not used: notably,
1324 this applies to platforms where the C double format is not IEEE 754 binary64,
1325 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1326 and Python's configure script is unable to determine how to change the FPU
1327 precision. On these platforms conversions use the platform strtod and dtoa,
1328 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001329
Georg Brandlba83f822010-03-14 09:50:54 +00001330- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1331 uses the correctly-rounded string <-> float conversions described above (when
1332 available), and so produces correctly rounded results that will display nicely
1333 under the float repr. There are two related small changes: (1) round now
1334 accepts any class with an ``__index__()`` method for its second argument (but
1335 no longer accepts floats for the second argument), and (2) an excessively
1336 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1337 raises an exception.

Philip Jenveyfab8be22009-11-17 02:42:26 +00001339- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
1340
Georg Brandlba83f822010-03-14 09:50:54 +00001341- Fix several issues with ``compile()``. The input can now contain Windows and
1342 Mac newlines and is no longer required to end in a newline.
Benjamin Petersone36199b2009-11-12 23:39:44 +00001343
Georg Brandlba83f822010-03-14 09:50:54 +00001344- Remove length limitation when constructing a complex number from a unicode
1345 string.

Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +00001372- Issue #1571184: The Unicode database contains properties for more characters.
1373 The tables for code points representing numeric values, white spaces or line
1374 breaks are now generated from the official Unicode Character Database files,
1375 and include information from the Unihan.txt file.

Georg Brandlba83f822010-03-14 09:50:54 +00001484- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1485 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1486 but with at least one decimal point and with a default precision
1487 of 12. Previously, the behavior the same but with a default precision of 6.
1488 This more closely matches ``str()``, and reduces surprises when adding

3117
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003118- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3119
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003120- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3121 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3122 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3123 ``printf`` function, whereas PyString_FromFormat has an independent
3124 implementation and uses "%zd" on all platforms for size_t values.
3125 This makes a difference on win64, where ``printf`` needs "%Id" to display
3126 64bit values.
3127
Benjamin Peterson97179b02008-09-09 20:55:01 +00003128- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
3129 error.
3130
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00003131- Issue #3777: long() applied to a float object now always return a long
3132 object; previously an int would be returned for small values. the __long__
3133 method is allowed to return either an int or a long, but the behaviour of
3134 float objects should not change to respect backward compatibility.
3135
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003136- Issue #3751: str.rpartition would perform a left-partition when called with
3137 a unicode argument.
3138
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00003139- Issue #3683: Fix compilation when --without-threads is given.
3140
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003141- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00003142 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003143 was correctly parsed but parsing of subsequent arguments failed.
3144
Vinay Sajip35e3b032008-09-01 14:33:59 +00003145- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003146 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3147 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3148 when given a tuple of classes as second argument, were looking up
3149 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3150 type object.
3151
Neal Norwitz18aa3882008-08-24 05:04:52 +00003152- Fix crashes on memory allocation failure found with failmalloc.
3153
3154- Fix memory leaks found with valgrind and update suppressions file.
3155
3156- Fix compiler warnings in opt mode which would lead to invalid memory reads.
3157
3158- Fix problem using wrong name in decimal module reported by pychecker.
3159
Christian Heimes7d4c3172008-08-22 19:47:25 +00003160- Silenced another compiler warning about a used but not defined
3161 function 'stringlib_contains_obj'.
3162
Benjamin Peterson712ee922008-08-24 18:10:20 +00003163- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
3164 ``__delslice__``.
3165
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00003166- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
3167 library targets in the Makefile.
3168
Gregory P. Smith980b99b2008-09-07 05:15:18 +00003169- Issue #1204: The configure script now tests for additional libraries
3170 that may be required when linking against readline. This fixes issues
3171 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
3172

Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00003181- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
3182 stack usage in the case of deeply nested objects.
3183
Guido van Rossume3c4fd92008-09-10 14:27:00 +00003184- Issue #3629: Fix sre "bytecode" validator for an end case.
3185
Martin v. Löwis24329ba2008-09-10 13:38:12 +00003186- Issue #3811: The Unicode database was updated to 5.1.
3187
Nick Coghland2e09382008-09-11 12:11:06 +00003188- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
3189 silent misbehaviour when a single instance is nested in multiple
3190 with statements, or when the methods are invoked in the wrong order.
3191
Vinay Sajip844f7412008-09-09 13:42:08 +00003192- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
3193
Nick Coghland2e09382008-09-11 12:11:06 +00003194- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00003195 return a list or None rather than a custom object.
3196
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00003197- Issue #1638033: Cookie.Morsel gained the httponly attribute.
3198
Antoine Pitrouebcd0ce2008-09-05 23:30:23 +00003199- Issue #3535: zipfile couldn't read some zip files larger than 2GB.

3221 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3222 for catch_warnings() also led to an improvement in the raising of a
3223 DeprecationWarning related to warnings.warn_explicit().
3224
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003225- The deprecation warnings for the old camelCase threading API were removed.

3230
Christian Heimes1cc69632008-08-22 20:10:27 +00003231- Fixed two format strings in the _collections module.
3232

3234 directory.
Benjamin Petersonf22c26e2008-09-01 14:13:43 +00003235
Gregory P. Smithd7122032008-09-02 05:36:11 +00003236- Issue #3708: os.urandom no longer goes into an infinite loop when passed a
3237 non-integer floating point number.
3238
Vinay Sajip65d66e12008-09-04 07:31:21 +00003239- Issue #3110: multiprocessing fails to compiel on solaris 10 due to missing

3247
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003248- Issue #2975: When compiling several extension modules with Visual Studio 2008
3249 from the same python interpreter, some environment variables would grow
3250 without limit.
3251
Benjamin Peterson37346b22008-08-23 20:27:43 +00003252- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
3253 exploitation of poor argument checking.
3254
Gerhard Häringef2276b2008-09-12 13:54:06 +00003255- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
3256
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00003257- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
3258 remaining ones have "pysqlite_" prefix.
3259
Gerhard Häringe6872eb2008-09-12 22:33:22 +00003260- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

Nick Coghland2e09382008-09-11 12:11:06 +00003267- Issue #3781: Add test.test_support.check_warnings() as a convenience
3268 wrapper for warnings.catch_warnings() that makes it easier to check
3269 that expected warning messages are being reported.
3270
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00003271- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003289What's New in Python 2.6 beta 3?
3290================================
3291
Barry Warsaw07a4a382008-08-21 01:15:08 +00003292*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003293
3294Core and Builtins
3295-----------------
3296
Guido van Rossumf8402962008-08-20 15:01:50 +00003297- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3298 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3299 extensions do not automatically benefit from the class attribute
3300 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3301 to their tp_flags field if they care. This is a backwards
3302 compatibility feature; in 3.0, all types will use the cache by
3303 default.
3304
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003305- Keyword arguments can now follow starred arguments. (``f(a, *args,
3306 keyword=23)`` is now valid syntax.)
3307
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003308- ctypes function pointers that are COM methods have a boolean True
3309 value again.
3310
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003311- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3312 by denying s# to parse objects that have a releasebuffer procedure,
3313 and introducing s*.
3314
Georg Brandl1e13ea92008-08-11 09:07:59 +00003315- Issue #3537: Fix an assertion failure when an empty but presized dict
3316 object was stored in the freelist.
3317
Mark Dickinsonb6467572008-08-04 21:30:09 +00003318- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3319 ValueError consistently across platforms.
3320
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003321- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3322 (64bit Unix, for example), unichr() would truncate its argument and return
3323 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3324
Neal Norwitze7d8be82008-07-31 17:17:14 +00003325- Apply security patches from Apple.
3326
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003327- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3328 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3329
Antoine Pitrou92f82162008-07-25 22:22:08 +00003330- Issue #1819: function calls with several named parameters are now on
3331 average 35% faster (as measured by pybench).
3332
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003333- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3334 the python debugger steps into a class statement: the free variables (local
3335 variables defined in an outer scope) would be deleted from the outer scope.
3336
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003337- Issue #2620: Overflow checking when allocating or reallocating memory
3338 was not always being done properly in some python types and extension
3339 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3340 all been updated to perform better checks and places in the code that
3341 would previously leak memory on the error path when such an allocation
3342 failed have been fixed.

3345-------
3346
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003347- Issue #3612: Added some missing basic types in ctypes.wintypes.
3348
Benjamin Petersone977ad42008-08-20 01:42:01 +00003349- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3350 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3351
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003352- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3353 version reported by these tools does not necessarily follow the python
3354 version numbering scheme, so the module is less strict when parsing it.
3355
Nick Coghlanf70385a2008-08-18 12:42:46 +00003356- Issue #2235: Added Py3k warnings for types which will become unhashable
3357 under the stricter __hash__ inheritance rules in 3.0. Several types
3358 which did not meet the rules for hash invariants and were already
3359 unhashable in 3.0 have now been explicitly flagged as unhashable in
3360 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3361 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3362
Brett Cannon88f801d2008-08-18 00:46:22 +00003363- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3364 imported into the module but exposed as part of the module's API.
3365
Brett Cannon7b96f072008-08-18 00:41:11 +00003366- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3367
Brett Cannon46225e72008-08-18 00:36:52 +00003368- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003370- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3371
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003372- Issue #3575: Incremental decoder's decode function now takes bytearray
3373 by using 's*' instead of 't#'.
3374
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003375- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003376 fails unicode conversion on 2nd parameter. (windows only)
3377
Facundo Batista94f243a2008-08-17 03:38:39 +00003378- Issue 2464. urllib2 now supports a malformation in the URL received
3379 in a redirect.
3380
Brett Cannonabe423e2008-08-16 21:47:07 +00003381- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003382 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003383
Facundo Batistaeb90b782008-08-16 14:44:07 +00003384- Issue #2776: fixed small issue when handling an URL with double slash
3385 after a 302 response in the case of not going through a proxy.
3386
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003387- Issue #2676: in the email package, content-type parsing was hanging on
3388 pathological input because of quadratic or exponential behaviour of a
3389 regular expression.
3390
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003391- Issue #3476: binary buffered reading through the new "io" library is now
3392 thread-safe.
3393
Brett Cannonbf3157b2008-08-14 05:00:03 +00003394- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3395 since mimetools itself is deprecated. Because modules are cached, all
3396 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3397
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003398- Issue #3134: shutil referenced undefined WindowsError symbol.
3399
Robert Schuppenies14646332008-08-10 11:01:53 +00003400- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3401 menu entries were not deleted.
3402
Brett Cannon83e81842008-08-09 23:30:55 +00003403- Copied the implementation of reduce() to _functools.reduce() to have a
3404 version that did not raise a DeprecationWarning under -3.
3405
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003406- Issue #3205: When iterating over a BZ2File fails allocating memory, raise

3410 to _sre.compile() will now be rejected. This should not affect anybody
3411 since the re.compile() function never generates invalid re-bytecode.

Benjamin Peterson01a24322008-07-28 23:35:27 +00003431- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003432 asking for a specific length. This problem only affected files opened
3433 using the new "io" module, not the built-in open() function.

3460 mode 0600 rather than 000 under Unix.
3461
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003462- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

3476
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003477- Issue #643841: The language reference now provides more detailed

3489-----------------
3490
Georg Brandl3e483f62008-07-16 22:57:41 +00003491- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3492 its methods now allow for items objects that can be converted to
3493 an integer using operator.index().
3494
Mark Dickinson64b7e502008-07-16 09:40:03 +00003495- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3496 produced a ValueError instead of giving the correct float.
3497
Eric Smitha5fa5a22008-07-16 00:11:49 +00003498- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3499 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3500
Mark Dickinson7103aa42008-07-15 19:08:33 +00003501- Issue #3008: the float type has a new instance method 'float.hex'
3502 and a new class method 'float.fromhex' to convert floating-point
3503 numbers to and from hexadecimal strings, respectively.
3504
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003505- Issue #2235: __hash__ is once again inherited by default. To allow
3506 collections.Hashable to remain meaningful in the presence of the
3507 default hash implementation (object.__hash__), it is now possible
3508 to explicit block inheritance of hash by setting __hash__=None at
3509 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3510 level.
3511
Nick Coghlanb028f502008-07-13 14:52:36 +00003512- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3513 the parent module cannot be found while performing an absolute import.
3514 This means that an incorrectly defined __package__ attribute will
3515 now only prevent relative imports in that module rather than causing
3516 all imports from that module to fail.
3517
Nick Coghlan14ff9942008-07-08 14:21:42 +00003518- Issue #2517: Allow unicode messages in Exceptions again by correctly

3528 another thread's dictionary.
3529
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003530- Issue #3004: Minor change to slice.indices(): the start and stop
3531 arguments are now treated identically, making the behaviour easier
3532 to describe and understand. For example, slice(None, -10,
3533 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3534 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3535 10, -1).
3536
Georg Brandl278fc502008-07-19 12:46:12 +00003537- Issue #3219: Calling a function with repeated keyword arguments,
3538 f(a=2, a=23), would not cause a syntax error. This was a regression
3539 from 2.4 caused by the switch to the new compiler.

3549 api functions without holding the GIL, which could lead to a fatal
3550 error when they failed.
3551
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003552- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003577- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3578 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003579 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003580 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003596- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

3984
Brett Cannonb61d8012008-05-11 23:39:04 +00003985- ``Lib/lib-old`` is now added to sys.path.
3986
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003987- On MacOS X it is now possible to install the framework in 64-bit
3988 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003989 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003990
3991 This is controlled by the configure argument ``--with-universal-archs``:
3992
3993 - ``--with-universal-archs=all``: install 4-way universal
3994
3995 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3996
3997 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3998
3999 This option should be used in combination with ``--enable-universalsdk=``.
4000
4001 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00004010
4011- The PyString functions have been renamed to PyBytes. A batch of
4012 defines were added so that the linker still sees the original
4013 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004051- Issue #1631171: Re-implement the 'warnings' module in C (the
4052 original Python code has been kept as backup). This will allow for
4053 using the 'warning's machinery in such places as the parser where
4054 use of pure Python code is not possible. Both the ``showarning()``
4055 and ``formatwarning()`` gain an optional 'line' argument which is
4056 not called by default for backwards-compatibility reasons. Setting
4057 ``warnings.showwarning()`` to an implementation that lacks support
4058 for the ``line`` argument will raise a DeprecationWarning.

4082
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004083- The getpass module has been improved on Unix. It now uses /dev/tty
4084 by default and uses stderr instead of stdout. A GetPassWarning is
4085 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004100- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004101 extension modules between 32 and 64 bit platforms. See the distutls

4114 so the controlled environment will more closely mirror the typical
4115 script environment. This supports setup.py scripts that refer to
4116 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004121- Issue #2550: The approach used by client/server code for obtaining
4122 ports to listen on in network-oriented tests has been refined in an
4123 effort to facilitate running multiple instances of the entire
4124 regression test suite in parallel without issue.
4125 test_support.bind_port() has been fixed such that it will always
4126 return a unique port -- which wasn't always the case with the
4127 previous implementation, especially if socket options had been set
4128 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4129 new implementation of bind_port() will actually raise an exception
4130 if it is passed an AF_INET/SOCK_STREAM socket with either the
4131 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4132 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4133 the socket it's been passed. This currently only applies to
4134 Windows. This option prevents any other sockets from binding to the
4135 host/port we've bound to, thus removing the possibility of the
4136 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4137 when a second SOCK_STREAM socket binds and accepts to a host/port
4138 that's already been bound by another socket. The optional preferred
4139 port parameter to bind_port() has been removed. Under no
4140 circumstances should tests be hard coding ports!
4141
4142 test_support.find_unused_port() has also been introduced, which will
4143 pass a temporary socket object to bind_port() in order to obtain an
4144 unused port. The temporary socket object is then closed and
4145 deleted, and the port is returned. This method should only be used
4146 for obtaining an unused port in order to pass to an external program
4147 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4148 a parameter to a server-oriented class that doesn't give you direct
4149 access to the underlying socket used.
4150
4151 Finally, test_support.HOST has been introduced, which should be used
4152 for the host argument of any relevant socket calls (i.e. bind and
4153 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004154
4155 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004156 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004157 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4158 test_asynchat and test_socket_ssl.
4159
Georg Brandl3ee81df2008-05-17 18:14:43 +00004160 It is now possible for multiple instances of the regression test
4161 suite to run in parallel without issue.

4428-----------------
4429
Fred Drakea8ee94b2008-03-01 02:45:07 +00004430- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004431 644. The mode is now inherited from the py file.

4434
4435- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004436
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004437- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004438 issue 215555 for a discussion.
4439
Eric Smitha73fbe72008-02-23 03:09:44 +00004440- Added the future_builtins module, which contains hex() and oct().
4441 These are the PEP 3127 version of these functions, designed to be
4442 compatible with the hex() and oct() builtins from Python 3.0. They
4443 differ slightly in their output formats from the existing, unchanged
4444 Python 2.6 builtins. The expected usage of the future_builtins
4445 module is:
4446 from future_builtins import hex, oct
4447
Eric Smith7ef40bf2008-02-20 23:34:22 +00004448- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4449 exponents for exponents with absolute value < 100. Follows C99
4450 standard. This is a change on Windows, which would use 3 digits.
4451 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4452 so that any alterations it does to the resulting string will be
4453 available in stringlib/formatter.h (for float.__format__).
4454
Eric Smith5a3c1352008-02-19 13:21:56 +00004455- Implemented PEP 3101, Advanced String Formatting. This adds a new
4456 builtin format(); a format() method for str and unicode; a
4457 __format__() method to object, str, unicode, int, long, float, and
4458 datetime; the class string.Formatter; and the C API
4459 PyObject_Format().
4460
Georg Brandl3ee81df2008-05-17 18:14:43 +00004461- Fixed several potential crashes, all caused by specially crafted
4462 __del__ methods exploiting objects in temporarily inconsistent
4463 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004464
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004465- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004466 prevent a possible crash: an Abstract Base Class would try to access
4467 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004472- Clear all free lists during a gc.collect() of the highest generation
4473 in order to allow pymalloc to free more arenas. Python may give back
4474 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004475
Georg Brandl3ee81df2008-05-17 18:14:43 +00004476- Issue #2045: Fix an infinite recursion triggered when printing a
4477 subclass of collections.defaultdict, if its default_factory is set
4478 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004479
Christian Heimesf75dbef2008-02-08 00:11:31 +00004480- Fixed a minor memory leak in dictobject.c. The content of the free
4481 list was not freed on interpreter shutdown.
4482
Georg Brandl21e99f42010-03-07 15:23:59 +00004483- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004484 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004485
Georg Brandl3ee81df2008-05-17 18:14:43 +00004486- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4487 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004488 to compact the internal free lists of pre-allocted ints and floats.
4489
Georg Brandl3ee81df2008-05-17 18:14:43 +00004490- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4491 calls. Python expected the return type int but the fork familie
4492 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004493
Georg Brandl3ee81df2008-05-17 18:14:43 +00004494- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4495 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004496
Georg Brandl3ee81df2008-05-17 18:14:43 +00004497- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4498 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004499
Georg Brandl3ee81df2008-05-17 18:14:43 +00004500- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4501 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00004503- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4504 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004505
Georg Brandl3ee81df2008-05-17 18:14:43 +00004506- Patch #1473257: generator objects gain a gi_code attribute. This is
4507 the same object as the func_code attribute of the function that
4508 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004509
Georg Brandl3ee81df2008-05-17 18:14:43 +00004510- Issue #1920: "while 0" statements were completely removed by the
4511 compiler, even in the presence of an "else" clause, which is
4512 supposed to be run when the condition is false. Now the compiler
4513 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004514
Guido van Rossumeead05f2008-01-24 18:21:02 +00004515- A few crashers fixed: weakref_in_del.py (issue #1377858);
4516 loosing_dict_ref.py (issue #1303614, test67.py);
4517 borrowed_ref_[34].py (not in tracker).
4518
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004519- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004520 suppressed while an extension is loaded by calling SetErrorMode in
4521 dynload_win.c. The error is still reported properly.
4522
Georg Brandl3ee81df2008-05-17 18:14:43 +00004523- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004524 several extension methods and modules do not work without unicode
4525 support.
4526
Georg Brandl26543b12008-01-21 18:36:51 +00004527- Issue #1882: when compiling code from a string, encoding cookies in the
4528 second line of code were not always recognized correctly.
4529
Georg Brandl14404b62008-01-19 19:27:05 +00004530- Issue #1679: "0x" was taken as a valid integer literal.
4531
Georg Brandl6caad7d2008-01-26 14:19:22 +00004532- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004533 added.
4534
Christian Heimesc94e2b52008-01-14 04:13:37 +00004535- sys.float_info / PyFloat_GetInfo: The floating point information
4536 object was converted from a dict to a specialized structseq object.
4537
Georg Brandl3ee81df2008-05-17 18:14:43 +00004538- Patch #1816: Added sys.flags structseq. It exposes the status of
4539 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004540
Georg Brandl3ee81df2008-05-17 18:14:43 +00004541- Objects/structseq.c: Implemented new structseq representation. The
4542 patch makes structseqs (e.g. the return value of os.stat) more
4543 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004544
Georg Brandl3ee81df2008-05-17 18:14:43 +00004545- Patch #1700288: added a type attribute cache that caches method
4546 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004547
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004548- Bug #1776: __import__() no longer accepts filenames on any platform.
4549 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004550
Georg Brandlaed6c662008-01-07 17:25:53 +00004551- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4552
Georg Brandl3ee81df2008-05-17 18:14:43 +00004553- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4554 envvar and sys.dont_write_bytecode attribute. All these can be set
4555 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004556
Georg Brandl3ee81df2008-05-17 18:14:43 +00004557- Improve some exception messages when Windows fails to load an
4558 extension module. Now we get for example '%1 is not a valid Win32
4559 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004560

Christian Heimes0a8143f2007-12-18 23:22:54 +00004566- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004567 and INF. float("nan"), float("inf") and float("-inf") now work on
4568 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004569
Georg Brandl3ee81df2008-05-17 18:14:43 +00004570- Compiler now generates simpler and faster code for dictionary
4571 literals. The oparg for BUILD_MAP now indicates an estimated
4572 dictionary size. There is a new opcode, STORE_MAP, for adding
4573 entries to the dictionary.

4585
Nick Coghlanef01d822007-12-03 12:55:17 +00004586- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00004602- Patch #1739468: Directories and zipfiles containing a __main__.py
4603 file can now be directly executed by passing their name to the
4604 interpreter. The directory/zipfile is automatically inserted as the
4605 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004606
Georg Brandl3ee81df2008-05-17 18:14:43 +00004607- Issue #1265: Fix a problem with sys.settrace, if the tracing
4608 function uses a generator expression when at the same time the
4609 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004610
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004611- sets and frozensets now have an isdisjoint() method.
4612
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004613- optimize the performance of builtin.sum().
4614
Neal Norwitz44f326e2007-10-05 05:29:17 +00004615- Fix warnings found by the new version of the Coverity checker.
4616
Georg Brandl21e99f42010-03-07 15:23:59 +00004617- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004618 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4619 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004620
Georg Brandl3ee81df2008-05-17 18:14:43 +00004621- Issue #1686386: Tuple's tp_repr did not take into account the
4622 possibility of having a self-referential tuple, which is possible
4623 from C code. Nor did object's tp_str consider that a type's tp_str
4624 could do something that could lead to an inifinite recursion.
4625 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4626 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004627
Georg Brandl3ee81df2008-05-17 18:14:43 +00004628- Issue #1164: It was possible to trigger deadlock when using the
4629 'print' statement to write to a file since the GIL was not released
4630 as needed. Now PyObject_Print() does the right thing along with
4631 various tp_print implementations of the built-in types and those in
4632 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004633
Georg Brandl3ee81df2008-05-17 18:14:43 +00004634- Issue #1147: Exceptions were directly allowing string exceptions in
4635 their throw() method even though string exceptions no longer
4636 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004638- Issue #1096: Prevent a segfault from getting the repr of a very
4639 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004640
Brett Cannon1e534b52007-09-07 04:18:30 +00004641- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004642 PyObject_Call() never calling back out to Python code to trigger
4643 recursion depth updates/checks. Required the creation of a static
4644 RuntimeError instance in case normalizing an exception put the
4645 recursion check value past its limit. Fixes crashers
4646 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004647

Neal Norwitz0ac60192007-05-27 04:08:54 +00004661- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004662 __*__ attributes. (Some already existed, e.g., __doc__ and
4663 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004664
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004665- Add -3 option to the interpreter to warn about features that are
4666 deprecated and will be changed/removed in Python 3.0.
4667
Georg Brandl2134e752007-05-21 20:34:16 +00004668- Patch #1686487: you can now pass any mapping after '**' in function
4669 calls.
4670
Collin Winter62903052007-05-18 23:11:24 +00004671- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004672 "except E as target:". This is to provide forwards compatibility
4673 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00004675- Deprecate BaseException.message as per PEP 352.
4676
Georg Brandl3ee81df2008-05-17 18:14:43 +00004677- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004678 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004679
Vinay Sajip8549ce32007-05-06 17:53:37 +00004680- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004681 setting a plain string, ie don't expand to single letter identifiers.
4682
Raymond Hettinger13936692007-04-11 18:40:58 +00004683- Request #1191699: Slices can now be pickled.
4684
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004685- Request #1193128: str.translate() now allows a None argument for
4686 translations that only remove characters without re-mapping the
4687 remaining characters.
4688
Georg Brandl5cb76c12007-03-21 09:00:39 +00004689- Patch #1682205: a TypeError while unpacking an iterable is no longer
4690 masked by a generic one with the message "unpack non-sequence".
4691
Neal Norwitzaa754b72007-03-21 06:39:48 +00004692- Remove unused file Python/fmod.c.
4693
Guido van Rossum143b5642007-03-23 04:58:42 +00004694- Bug #1683368: The object.__init__() and object.__new__() methods are
4695 now stricter in rejecting excess arguments. The only time when
4696 either allows excess arguments is when it is not overridden and the
4697 other one is. For backwards compatibility, when both are
4698 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004699 warning later). Also, type.__init__() insists on the same signature
4700 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004701
Georg Brandl3ee81df2008-05-17 18:14:43 +00004702- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4703 object to complex using its __complex__() method before falling back
4704 to the __float__() method. Therefore, the functions in the cmath
4705 module now can operate on objects that define a __complex__()
4706 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004707
Georg Brandl3ee81df2008-05-17 18:14:43 +00004708- Patch #1623563: allow __class__ assignment for classes with
4709 __slots__. The old and the new class are still required to have the
4710 same slot names.

4723
Georg Brandl7b9c5552007-03-12 14:30:05 +00004724- Bug #1678647: write a newline after printing an exception in any
4725 case, even when converting the value to a string failed.
4726
Georg Brandl871f1bc2007-03-12 13:17:36 +00004727- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004728 its argument, if it exists. If not, it will work like before. This
4729 allows customizing the output of dir() in the presence of a
4730 __getattr__().

Facundo Batistad918a652007-04-24 13:54:38 +00005253- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005254 the client's request was successfully received, understood, and

5265 (telnetlib, ftplib, smtplib and poplib). This is second part of the
5266 work started with create_connection() and timeout in httplib, and

5268
Vinay Sajip8549ce32007-05-06 17:53:37 +00005269- Patch #1676823: Added create_connection() to socket.py, which may be

Georg Brandl3ee81df2008-05-17 18:14:43 +00005295 AttributeError instead of an IOError when the server's response
5296 didn't contain a valid HTTP status line.

5328
Georg Brandl92a6bae2007-03-13 17:43:32 +00005329- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005330 are set for invalid interpolation sequences that would lead to
5331 errors on reading back those values.

5387 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00005780 time so that opening a database previously created with the DB_DUP
5781 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5782 opens. Specifically: dictionary assignment to a DB object will
5783 replace all values for a given key when the database allows
5784 duplicate values. DB users should use DB.put(k, v) when they want
5785 to store duplicates; not DB[k] = v.

5792 characters with ASCII value less than 32. Also, it correctly quotes
5793 dots only if they occur on a single line, as opposed to the previous
5794 behavior of quoting dots if they are the second character of any
5795 line.
