138 statement and correctly lookup the __enter__ and __exit__ special methods.
139
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000140- Issue #5829: complex("1e500") no longer raises OverflowError. This
141 makes it consistent with float("1e500") and interpretation of real

152 (1) inf and nan strings with trailing whitespace were incorrectly
153 rejected; (2) parsing of strings representing infinities and nans
154 was locale aware; and (3) the interpretation of fromhex('-nan')
155 didn't match that of float('-nan').
156
Eric Smitha985a3a2009-05-05 18:26:08 +0000157- Issue #5920: For float.__format__, change the behavior with the
158 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
159 to be like 'g' but with at least one decimal point and with a
160 default precision of 12. Previously, the behavior the same but with
161 a default precision of 6. This more closely matches str(), and
162 reduces surprises when adding alignment flags to the empty
163 presentation type. This also affects the new complex.__format__ in
164 the same way.
165
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000166- Issue #5890: in subclasses of 'property' the __doc__ attribute was

175
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000176- Issue #5864: Fix empty format code formatting for floats so that it
177 never gives more than the requested number of significant digits.
178
Eric Smithcac7af62009-04-27 19:04:37 +0000179- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
180 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
181

183 titlecase, but not their own uppercase.
184
Eric Smith068f0652009-04-25 21:40:15 +0000185- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
186 _PyOS_double_to_string or PyOS_double_to_string.
187

189
Mark Dickinson95bc9802009-04-24 12:46:53 +0000190- Issue #5816: complex(repr(z)) now recovers z exactly, even when
191 z involves nans, infs or negative zeros.
192
Eric Smithaca19e62009-04-22 13:29:05 +0000193- Implement PEP 378, Format Specifier for Thousands Separator, for
194 floats, ints, and longs.
195
196- Issue #5515: 'n' formatting for ints, longs, and floats handles
197 leading zero formatting poorly.
198
199- Issue #5772: For float.__format__, don't add a trailing ".0" if
200 we're using no type code and we have an exponent.

206 some builtin types.
207
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000208- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000209 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000210
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000211- Issue #5759: float() didn't call __float__ on str subclasses.
212

229 untrackable objects are not tracked by the garbage collector. This can
230 reduce the size of collections and therefore the garbage collection overhead
231 on long-running programs, depending on their particular use of datatypes.
232
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000233- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
234 improve its performance. Long divisions and remainder operations
235 are now between 50% and 150% faster.
236
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000237- Issue #4258: Make it possible to use base 2**30 instead of base
238 2**15 for the internal representation of integers, for performance
239 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
240 --enable-big-digits option to configure, which overrides the
241 default. Add sys.long_info structseq to provide information about
242 the internal format.
243
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000244- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
245 result traceback.__members__ no longer exists.)
246
Mark Dickinson6b265f12009-03-18 16:07:26 +0000247- Issue #4474: PyUnicode_FromWideChar now converts characters outside
248 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4

250
Eric Smith6f42edb2009-03-14 11:57:26 +0000251- Issue #5237: Allow auto-numbered fields in str.format(). For

253
Brett Cannon6c4cff02009-03-11 04:51:06 +0000254- Issue #3652: Make the 'line' argument for warnings.showwarning() a
255 requirement. Means the DeprecationWarning from Python 2.6 can go away.
256

265 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
266 on a 64-bit system.
267
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000268- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

273
Benjamin Petersone18ef192009-01-20 14:21:16 +0000274- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
275
Georg Brandl29c6a282009-04-05 20:23:13 +0000276- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000277 were suppressing all exceptions. These include list(), filter(), map(),
278 zip(), and bytearray().
279

306
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000307- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
308 an existing .py counterpart, override the co_filename attributes of all
309 code objects if the original filename is obsolete (which can happen if the
310 file has been renamed, moved, or if it is accessed through different paths).
311 Patch by Ziga Seilnacht and Jean-Paul Calderone.
312
Martin v. Löwis5344c992009-01-02 20:32:55 +0000313- Issue #4075: Use OutputDebugStringW in Py_FatalError.
314
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000315- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
316 file with `str' filename on Windows.
317
Antoine Pitrouaa687902009-01-01 14:11:22 +0000318- Issue #3680: Reference cycles created through a dict, set or deque iterator
319 did not get collected.
320
Nick Coghlan180e4002008-12-30 01:18:48 +0000321- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
322 where the tp_hash and tp_dict slots are both NULL.
323
Benjamin Peterson7af65562008-12-29 17:56:58 +0000324- Issue #4764: With io.open, IOError.filename is set when trying to open a
325 directory on POSIX systems.
326
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000327- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
328 systems.
329
Georg Brandl6425a2f2008-12-28 11:54:53 +0000330- Issue #4759: None is now allowed as the first argument of
331 bytearray.translate(). It was always allowed for bytes.translate().
332
Skip Montanarof205c132008-12-23 03:30:15 +0000333- Added test case to ensure attempts to read from a file opened for writing
334 fail.
335
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000336- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
337 print elapsed times, not only when some objects are uncollectable /
338 unreachable. Original patch by Neil Schemenauer.

346 context manager returns a value that cannot be converted to a bool.
347
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000348- Issue #4597: Fixed several opcodes that weren't always propagating
349 exceptions.
350
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000351- Issue #4445: Replace "sizeof(PyStringObject)" with
352 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
353 str instances. On a typical machine this saves 3 bytes of memory
354 (on average) per string allocation.
355
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000356- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
357 interpreter to abort ("Fatal Python error: Could not reset the stack!")
358 instead of throwing a MemoryError.
359
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000360- Issue #3689: The list reversed iterator now supports __length_hint__

364 module couldn't be imported and \N escapes were present.
365
Vinay Sajip213faca2008-12-03 23:22:58 +0000366- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000367 method on file objects with closefd=False. The file descriptor is still
368 kept open but the file object behaves like a closed file. The ``FileIO``
369 object also got a new readonly attribute ``closefd``.
370
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000371- Issue #4348: Some bytearray methods returned that didn't cause any change to
372 the bytearray, returned the same bytearray instead of a copy.
373
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000374- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.

379
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000380- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
381 exec statement.
382
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000383- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
384 method does not return iterators for the 4th and 5th items.
385
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000386- Issue #4209: Enabling unicode_literals and the print_function in the same
387 __future__ import didn't work.
388
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000389- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000390 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000391
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000392- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
393 returned a path longer than MAX_PATH. (But It's doubtful this code path is
394 really executed because I cannot move to such directory on win2k)
395
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000396- Issue #4069: When set.remove(element) is used with a set element, the element
397 is temporarily replaced with an equivalent frozenset. But the eventual
398 KeyError would always report the empty frozenset([]) as the missing key. Now
399 it correctly refers to the initial element.
400
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000401- Issue #4509: Various issues surrounding resize of bytearray objects to
402 which there are buffer exports.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000416- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
417 returned them on 64bit platforms.
418
Walter Dörwalded960ac2009-05-03 22:36:33 +0000419- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
420 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
421 step. This avoids problems with counting UTF-8 bytes that ignores the effect
422 of using the replace error handler in PyUnicode_DecodeUTF8().
423
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000424- Issue #3739: The unicode-internal encoder now reports the number of characters
425 consumed like any other encoder (instead of the number of bytes).

865 allows for much simpler resource allocation and deallocation during tests.
866
867- Issue #3379: unittest.main now takes an optional exit argument. If False main
868 doesn't call sys.exit allowing it to be used from the interactive interpreter.

877 called immediately before and after a test run.
878
Michael Foord345b2fe2009-04-02 03:20:38 +0000879- Issue #5663: better failure messages for unittest asserts. Default assertTrue
880 and assertFalse messages are now useful. TestCase has a longMessage attribute.
881 This defaults to False, but if set to True useful error messages are shown in
882 addition to explicit messages passed to assert methods.

935
936- The unittest.TestCase.assertEqual() now displays the differences in lists,

1529 leak-chasing test runs give sensible results. The previous method of

1558 it easy to import both normal and optimised versions of modules.
1559 test_heapq and test_warnings have been adjusted to use it, tests for
1560 other modules with both C and Python implementations in the stdlib
1561 can be adjusted to use it over time.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001669- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

1672 ``printf`` function, whereas PyString_FromFormat has an independent

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001692 was correctly parsed but parsing of subsequent arguments failed.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001694- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001695 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1696 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1697 when given a tuple of classes as second argument, were looking up
1698 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1699 type object.

1770 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1771 for catch_warnings() also led to an improvement in the raising of a

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001838What's New in Python 2.6 beta 3?
1839================================
1840
Barry Warsaw07a4a382008-08-21 01:15:08 +00001841*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001842
1843Core and Builtins
1844-----------------
1845
Guido van Rossumf8402962008-08-20 15:01:50 +00001846- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1847 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1848 extensions do not automatically benefit from the class attribute
1849 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1850 to their tp_flags field if they care. This is a backwards
1851 compatibility feature; in 3.0, all types will use the cache by
1852 default.
1853
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001854- Keyword arguments can now follow starred arguments. (``f(a, *args,
1855 keyword=23)`` is now valid syntax.)
1856
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001857- ctypes function pointers that are COM methods have a boolean True
1858 value again.
1859
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001860- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1861 by denying s# to parse objects that have a releasebuffer procedure,
1862 and introducing s*.
1863
Georg Brandl1e13ea92008-08-11 09:07:59 +00001864- Issue #3537: Fix an assertion failure when an empty but presized dict
1865 object was stored in the freelist.
1866
Mark Dickinsonb6467572008-08-04 21:30:09 +00001867- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1868 ValueError consistently across platforms.
1869
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001870- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1871 (64bit Unix, for example), unichr() would truncate its argument and return
1872 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1873
Neal Norwitze7d8be82008-07-31 17:17:14 +00001874- Apply security patches from Apple.
1875
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001876- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1877 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1878
Antoine Pitrou92f82162008-07-25 22:22:08 +00001879- Issue #1819: function calls with several named parameters are now on
1880 average 35% faster (as measured by pybench).
1881
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001882- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1883 the python debugger steps into a class statement: the free variables (local
1884 variables defined in an outer scope) would be deleted from the outer scope.
1885
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001886- Issue #2620: Overflow checking when allocating or reallocating memory
1887 was not always being done properly in some python types and extension
1888 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1889 all been updated to perform better checks and places in the code that
1890 would previously leak memory on the error path when such an allocation
1891 failed have been fixed.

1895
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001896- Issue #3612: Added some missing basic types in ctypes.wintypes.
1897
Benjamin Petersone977ad42008-08-20 01:42:01 +00001898- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1899 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1900
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001901- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1902 version reported by these tools does not necessarily follow the python
1903 version numbering scheme, so the module is less strict when parsing it.
1904
Nick Coghlanf70385a2008-08-18 12:42:46 +00001905- Issue #2235: Added Py3k warnings for types which will become unhashable
1906 under the stricter __hash__ inheritance rules in 3.0. Several types
1907 which did not meet the rules for hash invariants and were already
1908 unhashable in 3.0 have now been explicitly flagged as unhashable in
1909 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1910 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1911
Brett Cannon88f801d2008-08-18 00:46:22 +00001912- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1913 imported into the module but exposed as part of the module's API.
1914
Brett Cannon7b96f072008-08-18 00:41:11 +00001915- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1916
Brett Cannon46225e72008-08-18 00:36:52 +00001917- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001919- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1920
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001921- Issue #3575: Incremental decoder's decode function now takes bytearray
1922 by using 's*' instead of 't#'.
1923
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001924- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001925 fails unicode conversion on 2nd parameter. (windows only)
1926
Facundo Batista94f243a2008-08-17 03:38:39 +00001927- Issue 2464. urllib2 now supports a malformation in the URL received
1928 in a redirect.
1929
Brett Cannonabe423e2008-08-16 21:47:07 +00001930- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001931 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001932
Facundo Batistaeb90b782008-08-16 14:44:07 +00001933- Issue #2776: fixed small issue when handling an URL with double slash
1934 after a 302 response in the case of not going through a proxy.
1935
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001936- Issue #2676: in the email package, content-type parsing was hanging on
1937 pathological input because of quadratic or exponential behaviour of a
1938 regular expression.
1939
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001940- Issue #3476: binary buffered reading through the new "io" library is now
1941 thread-safe.
1942
Brett Cannonbf3157b2008-08-14 05:00:03 +00001943- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1944 since mimetools itself is deprecated. Because modules are cached, all
1945 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1946
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001947- Issue #3134: shutil referenced undefined WindowsError symbol.
1948
Robert Schuppenies14646332008-08-10 11:01:53 +00001949- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1950 menu entries were not deleted.
1951
Brett Cannon83e81842008-08-09 23:30:55 +00001952- Copied the implementation of reduce() to _functools.reduce() to have a
1953 version that did not raise a DeprecationWarning under -3.
1954
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001955- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1956 a MemoryError rather than silently stop the iteration.
1957
Guido van Rossum59ce9012008-08-09 14:55:34 +00001958- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1959 to _sre.compile() will now be rejected. This should not affect anybody
1960 since the re.compile() function never generates invalid re-bytecode.
1961
Skip Montanaroa032bf42008-08-08 22:52:51 +00001962- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1963 upon first access it can be automatically initialized from the csv file if
1964 it wasn't initialized during instantiation.
1965
Brett Cannon3aa2a492008-08-06 22:28:09 +00001966- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1967 the reload() built-in has been removed.
1968
Brett Cannon7e30b672008-08-04 21:52:25 +00001969- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001970 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2038-----------------
2039
Georg Brandl3e483f62008-07-16 22:57:41 +00002040- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2041 its methods now allow for items objects that can be converted to
2042 an integer using operator.index().
2043
Mark Dickinson64b7e502008-07-16 09:40:03 +00002044- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2045 produced a ValueError instead of giving the correct float.
2046
Eric Smitha5fa5a22008-07-16 00:11:49 +00002047- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2048 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2049
Mark Dickinson7103aa42008-07-15 19:08:33 +00002050- Issue #3008: the float type has a new instance method 'float.hex'
2051 and a new class method 'float.fromhex' to convert floating-point
2052 numbers to and from hexadecimal strings, respectively.
2053
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002054- Issue #2235: __hash__ is once again inherited by default. To allow
2055 collections.Hashable to remain meaningful in the presence of the
2056 default hash implementation (object.__hash__), it is now possible
2057 to explicit block inheritance of hash by setting __hash__=None at
2058 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2059 level.
2060
Nick Coghlanb028f502008-07-13 14:52:36 +00002061- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2062 the parent module cannot be found while performing an absolute import.
2063 This means that an incorrectly defined __package__ attribute will
2064 now only prevent relative imports in that module rather than causing
2065 all imports from that module to fail.
2066
Nick Coghlan14ff9942008-07-08 14:21:42 +00002067- Issue #2517: Allow unicode messages in Exceptions again by correctly

2077 another thread's dictionary.
2078
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002079- Issue #3004: Minor change to slice.indices(): the start and stop
2080 arguments are now treated identically, making the behaviour easier
2081 to describe and understand. For example, slice(None, -10,
2082 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2083 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2084 10, -1).
2085
Georg Brandl278fc502008-07-19 12:46:12 +00002086- Issue #3219: Calling a function with repeated keyword arguments,
2087 f(a=2, a=23), would not cause a syntax error. This was a regression
2088 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002126- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2127 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002128 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002129 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002145- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2555
Georg Brandl74a1dea2008-05-28 11:21:39 +00002556- Add ``PyType_Modified()`` as a public API to clear the type cache.
2557
2558- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00002559
2560- The PyString functions have been renamed to PyBytes. A batch of
2561 defines were added so that the linker still sees the original
2562 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002600- Issue #1631171: Re-implement the 'warnings' module in C (the
2601 original Python code has been kept as backup). This will allow for
2602 using the 'warning's machinery in such places as the parser where
2603 use of pure Python code is not possible. Both the ``showarning()``
2604 and ``formatwarning()`` gain an optional 'line' argument which is
2605 not called by default for backwards-compatibility reasons. Setting
2606 ``warnings.showwarning()`` to an implementation that lacks support
2607 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002649- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002650 extension modules between 32 and 64 bit platforms. See the distutls

2663 so the controlled environment will more closely mirror the typical
2664 script environment. This supports setup.py scripts that refer to
2665 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002670- Issue #2550: The approach used by client/server code for obtaining
2671 ports to listen on in network-oriented tests has been refined in an
2672 effort to facilitate running multiple instances of the entire
2673 regression test suite in parallel without issue.
2674 test_support.bind_port() has been fixed such that it will always
2675 return a unique port -- which wasn't always the case with the
2676 previous implementation, especially if socket options had been set
2677 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2678 new implementation of bind_port() will actually raise an exception
2679 if it is passed an AF_INET/SOCK_STREAM socket with either the
2680 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2681 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2682 the socket it's been passed. This currently only applies to
2683 Windows. This option prevents any other sockets from binding to the
2684 host/port we've bound to, thus removing the possibility of the
2685 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2686 when a second SOCK_STREAM socket binds and accepts to a host/port
2687 that's already been bound by another socket. The optional preferred
2688 port parameter to bind_port() has been removed. Under no
2689 circumstances should tests be hard coding ports!
2690
2691 test_support.find_unused_port() has also been introduced, which will
2692 pass a temporary socket object to bind_port() in order to obtain an
2693 unused port. The temporary socket object is then closed and
2694 deleted, and the port is returned. This method should only be used
2695 for obtaining an unused port in order to pass to an external program
2696 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2697 a parameter to a server-oriented class that doesn't give you direct
2698 access to the underlying socket used.
2699
2700 Finally, test_support.HOST has been introduced, which should be used
2701 for the host argument of any relevant socket calls (i.e. bind and
2702 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002703
2704 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002705 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002706 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2707 test_asynchat and test_socket_ssl.
2708
Georg Brandl3ee81df2008-05-17 18:14:43 +00002709 It is now possible for multiple instances of the regression test
2710 suite to run in parallel without issue.

2977-----------------
2978
Fred Drakea8ee94b2008-03-01 02:45:07 +00002979- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002980 644. The mode is now inherited from the py file.

2983
2984- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002985
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002986- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002987 issue 215555 for a discussion.
2988
Eric Smitha73fbe72008-02-23 03:09:44 +00002989- Added the future_builtins module, which contains hex() and oct().
2990 These are the PEP 3127 version of these functions, designed to be
2991 compatible with the hex() and oct() builtins from Python 3.0. They
2992 differ slightly in their output formats from the existing, unchanged
2993 Python 2.6 builtins. The expected usage of the future_builtins
2994 module is:
2995 from future_builtins import hex, oct
2996
Eric Smith7ef40bf2008-02-20 23:34:22 +00002997- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2998 exponents for exponents with absolute value < 100. Follows C99
2999 standard. This is a change on Windows, which would use 3 digits.
3000 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3001 so that any alterations it does to the resulting string will be
3002 available in stringlib/formatter.h (for float.__format__).
3003
Eric Smith5a3c1352008-02-19 13:21:56 +00003004- Implemented PEP 3101, Advanced String Formatting. This adds a new
3005 builtin format(); a format() method for str and unicode; a
3006 __format__() method to object, str, unicode, int, long, float, and
3007 datetime; the class string.Formatter; and the C API
3008 PyObject_Format().
3009
Georg Brandl3ee81df2008-05-17 18:14:43 +00003010- Fixed several potential crashes, all caused by specially crafted
3011 __del__ methods exploiting objects in temporarily inconsistent
3012 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003013
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003014- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003015 prevent a possible crash: an Abstract Base Class would try to access
3016 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003017

Georg Brandl3ee81df2008-05-17 18:14:43 +00003021- Clear all free lists during a gc.collect() of the highest generation
3022 in order to allow pymalloc to free more arenas. Python may give back
3023 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003024
Georg Brandl3ee81df2008-05-17 18:14:43 +00003025- Issue #2045: Fix an infinite recursion triggered when printing a
3026 subclass of collections.defaultdict, if its default_factory is set
3027 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003028
Christian Heimesf75dbef2008-02-08 00:11:31 +00003029- Fixed a minor memory leak in dictobject.c. The content of the free
3030 list was not freed on interpreter shutdown.
3031
Georg Brandl3ee81df2008-05-17 18:14:43 +00003032- Limit free list of method and builtin function objects to 256
3033 entries each.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003035- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3036 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003037 to compact the internal free lists of pre-allocted ints and floats.
3038
Georg Brandl3ee81df2008-05-17 18:14:43 +00003039- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3040 calls. Python expected the return type int but the fork familie
3041 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003042
Georg Brandl3ee81df2008-05-17 18:14:43 +00003043- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00003055- Patch #1473257: generator objects gain a gi_code attribute. This is
3056 the same object as the func_code attribute of the function that
3057 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003058
Georg Brandl3ee81df2008-05-17 18:14:43 +00003059- Issue #1920: "while 0" statements were completely removed by the
3060 compiler, even in the presence of an "else" clause, which is
3061 supposed to be run when the condition is false. Now the compiler

Guido van Rossumeead05f2008-01-24 18:21:02 +00003064- A few crashers fixed: weakref_in_del.py (issue #1377858);
3065 loosing_dict_ref.py (issue #1303614, test67.py);
3066 borrowed_ref_[34].py (not in tracker).
3067
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003068- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003069 suppressed while an extension is loaded by calling SetErrorMode in
3070 dynload_win.c. The error is still reported properly.
3071
Georg Brandl3ee81df2008-05-17 18:14:43 +00003072- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003073 several extension methods and modules do not work without unicode
3074 support.
3075
Georg Brandl26543b12008-01-21 18:36:51 +00003076- Issue #1882: when compiling code from a string, encoding cookies in the
3077 second line of code were not always recognized correctly.
3078
Georg Brandl14404b62008-01-19 19:27:05 +00003079- Issue #1679: "0x" was taken as a valid integer literal.
3080
Georg Brandl6caad7d2008-01-26 14:19:22 +00003081- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003082 added.
3083
Christian Heimesc94e2b52008-01-14 04:13:37 +00003084- sys.float_info / PyFloat_GetInfo: The floating point information
3085 object was converted from a dict to a specialized structseq object.
3086
Georg Brandl3ee81df2008-05-17 18:14:43 +00003087- Patch #1816: Added sys.flags structseq. It exposes the status of
3088 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003089
Georg Brandl3ee81df2008-05-17 18:14:43 +00003090- Objects/structseq.c: Implemented new structseq representation. The
3091 patch makes structseqs (e.g. the return value of os.stat) more
3092 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003093
Georg Brandl3ee81df2008-05-17 18:14:43 +00003094- Patch #1700288: added a type attribute cache that caches method
3095 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003096
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003097- Bug #1776: __import__() no longer accepts filenames on any platform.
3098 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003099
Georg Brandlaed6c662008-01-07 17:25:53 +00003100- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3101
Georg Brandl3ee81df2008-05-17 18:14:43 +00003102- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3103 envvar and sys.dont_write_bytecode attribute. All these can be set
3104 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003105
Georg Brandl3ee81df2008-05-17 18:14:43 +00003106- Improve some exception messages when Windows fails to load an
3107 extension module. Now we get for example '%1 is not a valid Win32
3108 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003109
Georg Brandl3ee81df2008-05-17 18:14:43 +00003110- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003112- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3113 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003114
Christian Heimes0a8143f2007-12-18 23:22:54 +00003115- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003116 and INF. float("nan"), float("inf") and float("-inf") now work on
3117 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003118
Georg Brandl3ee81df2008-05-17 18:14:43 +00003119- Compiler now generates simpler and faster code for dictionary
3120 literals. The oparg for BUILD_MAP now indicates an estimated
3121 dictionary size. There is a new opcode, STORE_MAP, for adding
3122 entries to the dictionary.

3140 running, and if the deallocation of its frames somehow calls the
3141 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003142

3147
Georg Brandl3ee81df2008-05-17 18:14:43 +00003148- Issue #1460: The utf-7 incremental decoder did not accept truncated
3149 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00003150
Georg Brandl3ee81df2008-05-17 18:14:43 +00003151- Patch #1739468: Directories and zipfiles containing a __main__.py
3152 file can now be directly executed by passing their name to the
3153 interpreter. The directory/zipfile is automatically inserted as the
3154 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003155
Georg Brandl3ee81df2008-05-17 18:14:43 +00003156- Issue #1265: Fix a problem with sys.settrace, if the tracing
3157 function uses a generator expression when at the same time the
3158 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003159
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003160- sets and frozensets now have an isdisjoint() method.
3161
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003162- optimize the performance of builtin.sum().
3163
Neal Norwitz44f326e2007-10-05 05:29:17 +00003164- Fix warnings found by the new version of the Coverity checker.
3165
Georg Brandl3ee81df2008-05-17 18:14:43 +00003166- The enumerate() builtin function is no longer bounded to sequences
3167 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3168 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003169
Georg Brandl3ee81df2008-05-17 18:14:43 +00003170- Issue #1686386: Tuple's tp_repr did not take into account the
3171 possibility of having a self-referential tuple, which is possible
3172 from C code. Nor did object's tp_str consider that a type's tp_str
3173 could do something that could lead to an inifinite recursion.
3174 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3175 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003176
Georg Brandl3ee81df2008-05-17 18:14:43 +00003177- Issue #1164: It was possible to trigger deadlock when using the
3178 'print' statement to write to a file since the GIL was not released
3179 as needed. Now PyObject_Print() does the right thing along with
3180 various tp_print implementations of the built-in types and those in
3181 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003182
Georg Brandl3ee81df2008-05-17 18:14:43 +00003183- Issue #1147: Exceptions were directly allowing string exceptions in
3184 their throw() method even though string exceptions no longer
3185 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003186
Georg Brandl3ee81df2008-05-17 18:14:43 +00003187- Issue #1096: Prevent a segfault from getting the repr of a very
3188 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003189
Brett Cannon1e534b52007-09-07 04:18:30 +00003190- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003191 PyObject_Call() never calling back out to Python code to trigger
3192 recursion depth updates/checks. Required the creation of a static
3193 RuntimeError instance in case normalizing an exception put the
3194 recursion check value past its limit. Fixes crashers
3195 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003196
Georg Brandl3ee81df2008-05-17 18:14:43 +00003197- Patch #1031213: Decode source line in SyntaxErrors back to its

3201 with %G.
3202
Georg Brandl3ee81df2008-05-17 18:14:43 +00003203- Prevent expandtabs() on string and unicode objects from causing a
3204 segfault when a large width is passed on 32-bit platforms.

Neal Norwitz0ac60192007-05-27 04:08:54 +00003210- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003211 __*__ attributes. (Some already existed, e.g., __doc__ and
3212 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003213
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003214- Add -3 option to the interpreter to warn about features that are
3215 deprecated and will be changed/removed in Python 3.0.
3216
Georg Brandl2134e752007-05-21 20:34:16 +00003217- Patch #1686487: you can now pass any mapping after '**' in function
3218 calls.
3219
Collin Winter62903052007-05-18 23:11:24 +00003220- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003221 "except E as target:". This is to provide forwards compatibility
3222 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003223
Brett Cannon229cee22007-05-05 01:34:02 +00003224- Deprecate BaseException.message as per PEP 352.
3225
Georg Brandl3ee81df2008-05-17 18:14:43 +00003226- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003227 inherited from a builtin base.
3228
Vinay Sajip8549ce32007-05-06 17:53:37 +00003229- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003230 setting a plain string, ie don't expand to single letter identifiers.
3231
Raymond Hettinger13936692007-04-11 18:40:58 +00003232- Request #1191699: Slices can now be pickled.
3233
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003234- Request #1193128: str.translate() now allows a None argument for
3235 translations that only remove characters without re-mapping the
3236 remaining characters.
3237
Georg Brandl5cb76c12007-03-21 09:00:39 +00003238- Patch #1682205: a TypeError while unpacking an iterable is no longer
3239 masked by a generic one with the message "unpack non-sequence".
3240
Neal Norwitzaa754b72007-03-21 06:39:48 +00003241- Remove unused file Python/fmod.c.
3242
Guido van Rossum143b5642007-03-23 04:58:42 +00003243- Bug #1683368: The object.__init__() and object.__new__() methods are
3244 now stricter in rejecting excess arguments. The only time when
3245 either allows excess arguments is when it is not overridden and the
3246 other one is. For backwards compatibility, when both are
3247 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003248 warning later). Also, type.__init__() insists on the same signature
3249 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003250
Georg Brandl3ee81df2008-05-17 18:14:43 +00003251- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3252 object to complex using its __complex__() method before falling back
3253 to the __float__() method. Therefore, the functions in the cmath
3254 module now can operate on objects that define a __complex__()
3255 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003257- Patch #1623563: allow __class__ assignment for classes with
3258 __slots__. The old and the new class are still required to have the
3259 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003260
Georg Brandl3ee81df2008-05-17 18:14:43 +00003261- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00003264- Patch #1462488: Python no longer segfaults when
3265 ``object.__reduce_ex__()`` is called with an object that is faking
3266 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003267
Georg Brandl3ee81df2008-05-17 18:14:43 +00003268- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00003271- Patch #1444529: the builtin compile() now accepts keyword arguments.
3272
Georg Brandl7b9c5552007-03-12 14:30:05 +00003273- Bug #1678647: write a newline after printing an exception in any
3274 case, even when converting the value to a string failed.
3275
Georg Brandl871f1bc2007-03-12 13:17:36 +00003276- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003277 its argument, if it exists. If not, it will work like before. This
3278 allows customizing the output of dir() in the presence of a
3279 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003280
Collin Winter276887b2007-03-12 16:11:39 +00003281- Patch #922167: Python no longer segfaults when faced with infinitely
3282 self-recursive reload() calls (as reported by bug #742342).
3283
Georg Brandl3ee81df2008-05-17 18:14:43 +00003284- Patch #1675981: remove unreachable code from ``type.__new__()``
3285 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003287- Patch #1491866: change the complex() constructor to allow
3288 parthensized forms. This means complex(repr(x)) now works instead of
3289 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003290
Georg Brandlaa2321b2007-03-07 00:40:28 +00003291- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003292 makes the filenames the warning module prints much more sensible
3293 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003294
Georg Brandl49aafc92007-03-07 00:34:46 +00003295- Variant of patch #697613: don't exit the interpreter on a SystemExit
3296 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003297 variable is given, but break into the interactive interpreter just
3298 like on other exceptions or normal program exit.

3796 only useful in Unix/Linux environments.
3797
Georg Brandlfb4b3b72007-04-24 15:27:13 +00003798- Bug #1706381: Specifying the SWIG option "-c++" in the setup.py file
3799 (as opposed to the command line) will now write file names ending in
3800 ".cpp" too.
3801
Facundo Batistad918a652007-04-24 13:54:38 +00003802- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003803 the client's request was successfully received, understood, and
3804 accepted. Now in these cases no error is raised in urllib (issue
3805 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00003806
Georg Brandl3ee81df2008-05-17 18:14:43 +00003807- Bug #1290505: time.strptime's internal cache of locale information

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003813- Added a timeout parameter to the constructor of other protocols
3814 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3815 work started with create_connection() and timeout in httplib, and
3816 closes patch #723312.
3817
Vinay Sajip8549ce32007-05-06 17:53:37 +00003818- Patch #1676823: Added create_connection() to socket.py, which may be
3819 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00003820 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00003821
Martin v. Löwis0af33882007-03-23 13:27:15 +00003822- Bug #978833: Revert r50844, as it broke _socketobject.dup.
3823

Georg Brandl3ee81df2008-05-17 18:14:43 +00003829- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
3830 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00003831 directories.
3832
Georg Brandl8f06d022007-03-16 07:55:09 +00003833- Bug #1681228: the webbrowser module now correctly uses the default
3834 GNOME or KDE browser, depending on whether there is a session of one

3837
Collin Winter6f187742007-03-16 22:16:08 +00003838- Patch #1339796: add a relpath() function to os.path.

3841 initialization failed.
3842
Georg Brandlf66b6032007-03-14 08:27:52 +00003843- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00003844 AttributeError instead of an IOError when the server's response
3845 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003846
Georg Brandl3ee81df2008-05-17 18:14:43 +00003847- Patch #957650: "%var%" environment variable references are now
3848 properly expanded in ntpath.expandvars(), also "~user" home
3849 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00003850
Georg Brandl3ee81df2008-05-17 18:14:43 +00003851- Patch #1429539: pdb now correctly initializes the __main__ module
3852 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003853 correctly now.
3854
Georg Brandlbad6f192007-03-13 21:32:56 +00003855- The nonobvious commands.getstatus() function is now deprecated.

3861
Georg Brandl3ee81df2008-05-17 18:14:43 +00003862- Patch #1530482: add pydoc.render_doc() which returns the
3863 documentation for a thing instead of paging it to stdout, which
3864 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00003865
Georg Brandl3ee81df2008-05-17 18:14:43 +00003866- Patch #1533909: the timeit module now accepts callables in addition

3872 parameter which can be set to False to prevent the default
3873 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00003874
Georg Brandl9e6b4702007-03-13 18:15:41 +00003875- Patch #1581073: add a flag to textwrap that prevents the dropping of
3876 whitespace while wrapping.
3877
Georg Brandl92a6bae2007-03-13 17:43:32 +00003878- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003879 are set for invalid interpolation sequences that would lead to
3880 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00003881

3894
Georg Brandl94fe3f52007-03-13 09:32:11 +00003895- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00003896 field names in its exception message if you try to write a record
3897 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00003915
Andrew M. Kuchlinge45a77a2008-01-19 16:26:13 +00003916- Patch #742598: Add .timeout attribute to SocketServer that calls

3923 returned string up to the first NUL character.
3924

3934
Georg Brandl3ee81df2008-05-17 18:14:43 +00003935- unittest now verifies more of its assumptions. In particular,
3936 TestCase and TestSuite subclasses (not instances) are no longer
3937 accepted in TestSuite.addTest(). This should cause no
3938 incompatibility since it never made sense with ordinary subclasses
3939 -- the failure just occurred later, with a more cumbersome
3940 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00003941

3949 given a unicode argument and os.listdir() returns unicode filenames.
3950
Georg Brandl3ee81df2008-05-17 18:14:43 +00003951- Patch #1673619: setup.py identifies extension modules it doesn't
3952 know how to build and those it knows how to build but that fail to
3953 build.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004328- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00004329 time so that opening a database previously created with the DB_DUP
4330 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4331 opens. Specifically: dictionary assignment to a DB object will
4332 replace all values for a given key when the database allows
4333 duplicate values. DB users should use DB.put(k, v) when they want
4334 to store duplicates; not DB[k] = v.

4341 characters with ASCII value less than 32. Also, it correctly quotes
4342 dots only if they occur on a single line, as opposed to the previous
4343 behavior of quoting dots if they are the second character of any
4344 line.
