42 with invalid values.

Eric Smithc4ab8332009-11-29 17:40:57 +000044- Issue #3382: 'F' formatting for float and complex now convert the
45 result to upper case. This only affects 'inf' and 'nan', since 'f'
46 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +000047
Mark Dickinson9dd5e162009-11-23 20:54:09 +000048- Remove switch from "%f" formatting to "%g" formatting for floats
49 larger than 1e50 in absolute value.
50
Mark Dickinson18cfada2009-11-23 18:46:41 +000051- Remove restrictions on precision when formatting floats. E.g.,
52 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
53 requested 120 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +000059- Issue #7085: Fix crash when importing some extensions in a thread
60 on MacOSX 10.6.
61
Mark Dickinsonb678de82009-11-19 18:41:49 +000062- Issue #7117: repr(x) for a float x returns a result based on the
63 shortest decimal string that's guaranteed to round back to x under
64 correct rounding (with round-half-to-even rounding mode).
65 Previously it gave a string based on rounding x to 17 decimal digits.
66 repr(x) for a complex number behaves similarly. On platforms where
67 the correctly-rounded strtod and dtoa code is not supported (see below),
68 repr is unchanged.
69
70- Issue #7117: On almost all platforms: float-to-string and
71 string-to-float conversions within Python are now correctly rounded.
72 Places these conversions occur include: str for floats and complex
73 numbers; the float and complex constructors; old-style and new-style
74 numeric formatting; serialization and deserialization of floats and
75 complex numbers using marshal, pickle and json; parsing of float and
76 imaginary literals in Python code; Decimal-to-float conversion.
77
78 The conversions use a Python-adapted version of David Gay's
79 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
80 functions. This code is supported on Windows, and on Unix-like
81 platforms using gcc, icc or suncc as the C compiler. There may be a
82 small number of platforms on which correct operation of this code
83 cannot be guaranteed, so the code is not used: notably, this applies
84 to platforms where the C double format is not IEEE 754 binary64, and
85 to platforms on x86 hardware where the x87 FPU is set to 64-bit
86 precision and Python's configure script is unable to determine how
87 to change the FPU precision. On these platforms conversions use the
88 platform strtod and dtoa, as before.
89
Mark Dickinsonbd15a062009-11-18 19:33:35 +000090- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +000091 now uses the correctly-rounded string <-> float conversions
92 described above (when available), and so produces correctly rounded
93 results that will display nicely under the float repr. There are
94 two related small changes: (1) round now accepts any class with an
95 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +000096 floats for the second argument), and (2) an excessively large second
97 integer argument (e.g., round(1.234, 10**100)) no longer raises an
98 exception.
99
Philip Jenveyfab8be22009-11-17 02:42:26 +0000100- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
101

243 was locale aware; and (3) the interpretation of fromhex('-nan')
244 didn't match that of float('-nan').
245
Eric Smitha985a3a2009-05-05 18:26:08 +0000246- Issue #5920: For float.__format__, change the behavior with the
247 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
248 to be like 'g' but with at least one decimal point and with a
249 default precision of 12. Previously, the behavior the same but with
250 a default precision of 6. This more closely matches str(), and
251 reduces surprises when adding alignment flags to the empty
252 presentation type. This also affects the new complex.__format__ in
253 the same way.

Ronald Oussorene0154ed2009-03-30 23:10:35 +0000314- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
315 the end sys.path, for compatibility with the system install of Python.
316
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000317- Issue #4688: Add a heuristic so that tuples and dicts containing only
318 untrackable objects are not tracked by the garbage collector. This can
319 reduce the size of collections and therefore the garbage collection overhead
320 on long-running programs, depending on their particular use of datatypes.
321
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000322- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

324 are now between 50% and 150% faster.
325
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000326- Issue #4258: Make it possible to use base 2**30 instead of base
327 2**15 for the internal representation of integers, for performance
328 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
329 --enable-big-digits option to configure, which overrides the
330 default. Add sys.long_info structseq to provide information about
331 the internal format.
332
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000333- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
334 result traceback.__members__ no longer exists.)
335
Mark Dickinson6b265f12009-03-18 16:07:26 +0000336- Issue #4474: PyUnicode_FromWideChar now converts characters outside
337 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
338 and sizeof(Py_UNICODE) == 2.
339
Eric Smith6f42edb2009-03-14 11:57:26 +0000340- Issue #5237: Allow auto-numbered fields in str.format(). For
341 example: '{} {}'.format(1, 2) == '1 2'.
342
Brett Cannon6c4cff02009-03-11 04:51:06 +0000343- Issue #3652: Make the 'line' argument for warnings.showwarning() a
344 requirement. Means the DeprecationWarning from Python 2.6 can go away.
345
Eric Smithe9fb6862009-02-20 14:02:36 +0000346- Issue #5247: Improve error message when unknown format codes are
347 used when using str.format() with str, unicode, long, int, and
348 float arguments.
349
Raymond Hettinger08259e82009-02-18 23:10:19 +0000350- Running Python with the -3 option now also warns about classic division
351 for ints and longs.
352
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000353- Issue #5260: Long integers now consume less memory: average
354 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
355 on a 64-bit system.
356
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000357- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
358 rotating the object pointer by 4 bits to the right.

Mark Dickinsonc97c9092009-02-09 14:18:43 +0000360- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
361 it now forces its argument to double before testing for infinity.
362
Benjamin Petersone18ef192009-01-20 14:21:16 +0000363- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
364
Georg Brandl29c6a282009-04-05 20:23:13 +0000365- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000366 were suppressing all exceptions. These include list(), filter(), map(),
367 zip(), and bytearray().
368
Benjamin Peterson596d3062009-01-19 15:42:23 +0000369- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
370 functions.
371
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000372- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

376
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000377- Issue #4935: The overflow checking code in the expandtabs() method common
378 to str, bytes and bytearray could be optimized away by the compiler, letting
379 the interpreter segfault instead of raising an error.
380
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000381- Issue #3720: Fix a crash when an iterator modifies its class and removes its

387
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000388- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
389 collecting the oldest generation) so that allocating lots of objects without
390 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000391 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000392 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

395
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000396- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
397 an existing .py counterpart, override the co_filename attributes of all
398 code objects if the original filename is obsolete (which can happen if the
399 file has been renamed, moved, or if it is accessed through different paths).
400 Patch by Ziga Seilnacht and Jean-Paul Calderone.
401
Martin v. Löwis5344c992009-01-02 20:32:55 +0000402- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000404- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
405 file with `str' filename on Windows.
406
Antoine Pitrouaa687902009-01-01 14:11:22 +0000407- Issue #3680: Reference cycles created through a dict, set or deque iterator
408 did not get collected.
409
Nick Coghlan180e4002008-12-30 01:18:48 +0000410- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
411 where the tp_hash and tp_dict slots are both NULL.
412
Benjamin Peterson7af65562008-12-29 17:56:58 +0000413- Issue #4764: With io.open, IOError.filename is set when trying to open a

415
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000416- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
417 systems.
418
Georg Brandl6425a2f2008-12-28 11:54:53 +0000419- Issue #4759: None is now allowed as the first argument of
420 bytearray.translate(). It was always allowed for bytes.translate().
421
Skip Montanarof205c132008-12-23 03:30:15 +0000422- Added test case to ensure attempts to read from a file opened for writing
423 fail.
424
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000425- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
426 print elapsed times, not only when some objects are uncollectable /
427 unreachable. Original patch by Neil Schemenauer.
428
Mark Dickinson1a707982008-12-17 16:14:37 +0000429- Issue #3439: Add a bit_length method to int and long.

432 Original patch by Neal Norwitz.
433
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000434- Issue #4597: Fixed exception handling when the __exit__ function of a
435 context manager returns a value that cannot be converted to a bool.
436
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000437- Issue #4597: Fixed several opcodes that weren't always propagating
438 exceptions.
439
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000440- Issue #4445: Replace "sizeof(PyStringObject)" with
441 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
442 str instances. On a typical machine this saves 3 bytes of memory
443 (on average) per string allocation.
444
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000445- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
446 interpreter to abort ("Fatal Python error: Could not reset the stack!")
447 instead of throwing a MemoryError.
448
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000449- Issue #3689: The list reversed iterator now supports __length_hint__
450 instead of __len__. Behavior now matches other reversed iterators.
451
Benjamin Petersonc078f922008-11-21 22:27:24 +0000452- Issue #4367: Python would segfault during compiling when the unicodedata
453 module couldn't be imported and \N escapes were present.
454
Vinay Sajip213faca2008-12-03 23:22:58 +0000455- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000456 method on file objects with closefd=False. The file descriptor is still
457 kept open but the file object behaves like a closed file. The ``FileIO``
458 object also got a new readonly attribute ``closefd``.
459
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000460- Issue #4348: Some bytearray methods returned that didn't cause any change to
461 the bytearray, returned the same bytearray instead of a copy.
462
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000463- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
464
Benjamin Peterson273c2332008-11-17 22:39:09 +0000465- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
466
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000467- Issue #4048: The parser module now correctly validates relative imports.
468
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000469- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
470 exec statement.
471
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000472- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
473 method does not return iterators for the 4th and 5th items.
474
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000475- Issue #4209: Enabling unicode_literals and the print_function in the same
476 __future__ import didn't work.
477
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000478- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000479 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000480
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000481- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
482 returned a path longer than MAX_PATH. (But It's doubtful this code path is
483 really executed because I cannot move to such directory on win2k)
484
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000485- Issue #4069: When set.remove(element) is used with a set element, the element
486 is temporarily replaced with an equivalent frozenset. But the eventual
487 KeyError would always report the empty frozenset([]) as the missing key. Now
488 it correctly refers to the initial element.
489
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000490- Issue #4509: Various issues surrounding resize of bytearray objects to
491 which there are buffer exports.
492
Benjamin Peterson8d5934b2008-12-27 18:24:11 +0000493- Issue #4748: Lambda generators no longer return a value.

501
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000502- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
503 to avoid compiler warnings.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000505- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
506 returned them on 64bit platforms.
507
Walter Dörwalded960ac2009-05-03 22:36:33 +0000508- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
509 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
510 step. This avoids problems with counting UTF-8 bytes that ignores the effect
511 of using the replace error handler in PyUnicode_DecodeUTF8().
512
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000513- Issue #3739: The unicode-internal encoder now reports the number of characters
514 consumed like any other encoder (instead of the number of bytes).
515
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000516- Issue #2422: When compiled with the ``--with-valgrind`` option, the
517 pymalloc allocator will be automatically disabled when running under
518 Valgrind. This gives improved memory leak detection when running
519 under Valgrind, while taking advantage of pymalloc at other times.

1753 leak-chasing test runs give sensible results. The previous method of

1897
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001898- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1899 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1900 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1901 ``printf`` function, whereas PyString_FromFormat has an independent
1902 implementation and uses "%zd" on all platforms for size_t values.
1903 This makes a difference on win64, where ``printf`` needs "%Id" to display
1904 64bit values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001921 was correctly parsed but parsing of subsequent arguments failed.
1922
Vinay Sajip35e3b032008-09-01 14:33:59 +00001923- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001924 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1925 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1926 when given a tuple of classes as second argument, were looking up
1927 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1928 type object.
1929

1999 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2000 for catch_warnings() also led to an improvement in the raising of a
2001 DeprecationWarning related to warnings.warn_explicit().
2002
Benjamin Peterson973e6c22008-09-01 23:12:58 +00002003- The deprecation warnings for the old camelCase threading API were removed.

2024 _check_logger_class from multiprocessing.
2025
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002026- Issue #2975: When compiling several extension modules with Visual Studio 2008
2027 from the same python interpreter, some environment variables would grow
2028 without limit.
2029
Benjamin Peterson37346b22008-08-23 20:27:43 +00002030- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
2031 exploitation of poor argument checking.
2032
Gerhard Häringef2276b2008-09-12 13:54:06 +00002033- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
2034
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00002035- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
2036 remaining ones have "pysqlite_" prefix.
2037
Gerhard Häringe6872eb2008-09-12 22:33:22 +00002038- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

2046 wrapper for warnings.catch_warnings() that makes it easier to check
2047 that expected warning messages are being reported.
2048
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00002049- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002067What's New in Python 2.6 beta 3?
2068================================
2069
Barry Warsaw07a4a382008-08-21 01:15:08 +00002070*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002071
2072Core and Builtins
2073-----------------
2074
Guido van Rossumf8402962008-08-20 15:01:50 +00002075- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2076 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2077 extensions do not automatically benefit from the class attribute
2078 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2079 to their tp_flags field if they care. This is a backwards
2080 compatibility feature; in 3.0, all types will use the cache by
2081 default.
2082
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002083- Keyword arguments can now follow starred arguments. (``f(a, *args,
2084 keyword=23)`` is now valid syntax.)
2085
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002086- ctypes function pointers that are COM methods have a boolean True
2087 value again.
2088
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002089- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2090 by denying s# to parse objects that have a releasebuffer procedure,
2091 and introducing s*.
2092
Georg Brandl1e13ea92008-08-11 09:07:59 +00002093- Issue #3537: Fix an assertion failure when an empty but presized dict
2094 object was stored in the freelist.
2095
Mark Dickinsonb6467572008-08-04 21:30:09 +00002096- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2097 ValueError consistently across platforms.
2098
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002099- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2100 (64bit Unix, for example), unichr() would truncate its argument and return
2101 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2102
Neal Norwitze7d8be82008-07-31 17:17:14 +00002103- Apply security patches from Apple.
2104
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002105- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2106 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2107
Antoine Pitrou92f82162008-07-25 22:22:08 +00002108- Issue #1819: function calls with several named parameters are now on
2109 average 35% faster (as measured by pybench).
2110
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002111- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2112 the python debugger steps into a class statement: the free variables (local
2113 variables defined in an outer scope) would be deleted from the outer scope.
2114
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002115- Issue #2620: Overflow checking when allocating or reallocating memory
2116 was not always being done properly in some python types and extension
2117 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2118 all been updated to perform better checks and places in the code that
2119 would previously leak memory on the error path when such an allocation
2120 failed have been fixed.
2121
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002122Library
2123-------
2124

2126
Benjamin Petersone977ad42008-08-20 01:42:01 +00002127- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2128 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2129
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002130- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2131 version reported by these tools does not necessarily follow the python
2132 version numbering scheme, so the module is less strict when parsing it.
2133
Nick Coghlanf70385a2008-08-18 12:42:46 +00002134- Issue #2235: Added Py3k warnings for types which will become unhashable
2135 under the stricter __hash__ inheritance rules in 3.0. Several types
2136 which did not meet the rules for hash invariants and were already
2137 unhashable in 3.0 have now been explicitly flagged as unhashable in
2138 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2139 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2140
Brett Cannon88f801d2008-08-18 00:46:22 +00002141- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2149
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002150- Issue #3575: Incremental decoder's decode function now takes bytearray
2151 by using 's*' instead of 't#'.
2152
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002153- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002154 fails unicode conversion on 2nd parameter. (windows only)
2155
Facundo Batista94f243a2008-08-17 03:38:39 +00002156- Issue 2464. urllib2 now supports a malformation in the URL received
2157 in a redirect.
2158
Brett Cannonabe423e2008-08-16 21:47:07 +00002159- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002160 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002161
Facundo Batistaeb90b782008-08-16 14:44:07 +00002162- Issue #2776: fixed small issue when handling an URL with double slash
2163 after a 302 response in the case of not going through a proxy.
2164
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002165- Issue #2676: in the email package, content-type parsing was hanging on
2166 pathological input because of quadratic or exponential behaviour of a
2167 regular expression.
2168
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002169- Issue #3476: binary buffered reading through the new "io" library is now
2170 thread-safe.
2171
Brett Cannonbf3157b2008-08-14 05:00:03 +00002172- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2173 since mimetools itself is deprecated. Because modules are cached, all
2174 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2175
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002176- Issue #3134: shutil referenced undefined WindowsError symbol.
2177
Robert Schuppenies14646332008-08-10 11:01:53 +00002178- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2179 menu entries were not deleted.
2180
Brett Cannon83e81842008-08-09 23:30:55 +00002181- Copied the implementation of reduce() to _functools.reduce() to have a
2182 version that did not raise a DeprecationWarning under -3.
2183
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002184- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2185 a MemoryError rather than silently stop the iteration.
2186
Guido van Rossum59ce9012008-08-09 14:55:34 +00002187- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2188 to _sre.compile() will now be rejected. This should not affect anybody
2189 since the re.compile() function never generates invalid re-bytecode.
2190
Skip Montanaroa032bf42008-08-08 22:52:51 +00002191- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2192 upon first access it can be automatically initialized from the csv file if
2193 it wasn't initialized during instantiation.

Brett Cannon3aa2a492008-08-06 22:28:09 +00002195- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2196 the reload() built-in has been removed.
2197
Brett Cannon7e30b672008-08-04 21:52:25 +00002198- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002199 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00002210 asking for a specific length. This problem only affected files opened
2211 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002212

2238 mode 0600 rather than 000 under Unix.
2239
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002240- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2241 argument in python 2.5, this broke code that subclassed Popen to include its

2267-----------------
2268
Georg Brandl3e483f62008-07-16 22:57:41 +00002269- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2270 its methods now allow for items objects that can be converted to
2271 an integer using operator.index().
2272
Mark Dickinson64b7e502008-07-16 09:40:03 +00002273- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2274 produced a ValueError instead of giving the correct float.
2275
Eric Smitha5fa5a22008-07-16 00:11:49 +00002276- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2277 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2278
Mark Dickinson7103aa42008-07-15 19:08:33 +00002279- Issue #3008: the float type has a new instance method 'float.hex'
2280 and a new class method 'float.fromhex' to convert floating-point
2281 numbers to and from hexadecimal strings, respectively.
2282
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002283- Issue #2235: __hash__ is once again inherited by default. To allow
2284 collections.Hashable to remain meaningful in the presence of the

Nick Coghlanb028f502008-07-13 14:52:36 +00002290- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2291 the parent module cannot be found while performing an absolute import.
2292 This means that an incorrectly defined __package__ attribute will
2293 now only prevent relative imports in that module rather than causing
2294 all imports from that module to fail.

Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002308- Issue #3004: Minor change to slice.indices(): the start and stop
2309 arguments are now treated identically, making the behaviour easier
2310 to describe and understand. For example, slice(None, -10,
2311 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2312 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2313 10, -1).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002829- Issue #1631171: Re-implement the 'warnings' module in C (the
2830 original Python code has been kept as backup). This will allow for
2831 using the 'warning's machinery in such places as the parser where
2832 use of pure Python code is not possible. Both the ``showarning()``
2833 and ``formatwarning()`` gain an optional 'line' argument which is
2834 not called by default for backwards-compatibility reasons. Setting
2835 ``warnings.showwarning()`` to an implementation that lacks support
2836 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002899- Issue #2550: The approach used by client/server code for obtaining
2900 ports to listen on in network-oriented tests has been refined in an
2901 effort to facilitate running multiple instances of the entire
2902 regression test suite in parallel without issue.
2903 test_support.bind_port() has been fixed such that it will always
2904 return a unique port -- which wasn't always the case with the
2905 previous implementation, especially if socket options had been set
2906 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2907 new implementation of bind_port() will actually raise an exception
2908 if it is passed an AF_INET/SOCK_STREAM socket with either the
2909 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2910 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2911 the socket it's been passed. This currently only applies to
2912 Windows. This option prevents any other sockets from binding to the
2913 host/port we've bound to, thus removing the possibility of the
2914 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2915 when a second SOCK_STREAM socket binds and accepts to a host/port
2916 that's already been bound by another socket. The optional preferred
2917 port parameter to bind_port() has been removed. Under no
2918 circumstances should tests be hard coding ports!
2919
2920 test_support.find_unused_port() has also been introduced, which will
2921 pass a temporary socket object to bind_port() in order to obtain an
2922 unused port. The temporary socket object is then closed and
2923 deleted, and the port is returned. This method should only be used
2924 for obtaining an unused port in order to pass to an external program
2925 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2926 a parameter to a server-oriented class that doesn't give you direct
2927 access to the underlying socket used.
2928
2929 Finally, test_support.HOST has been introduced, which should be used
2930 for the host argument of any relevant socket calls (i.e. bind and
2931 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002932
2933 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002934 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002935 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2936 test_asynchat and test_socket_ssl.
2937
Georg Brandl3ee81df2008-05-17 18:14:43 +00002938 It is now possible for multiple instances of the regression test
2939 suite to run in parallel without issue.

3205Core and builtins
3206-----------------
3207
Fred Drakea8ee94b2008-03-01 02:45:07 +00003208- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003209 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003210
Georg Brandlad61bc82008-02-23 15:11:18 +00003211- Issue #2067: file.__exit__() now calls subclasses' close() method.
3212
3213- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003214
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003215- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003216 issue 215555 for a discussion.
3217
Eric Smitha73fbe72008-02-23 03:09:44 +00003218- Added the future_builtins module, which contains hex() and oct().
3219 These are the PEP 3127 version of these functions, designed to be
3220 compatible with the hex() and oct() builtins from Python 3.0. They
3221 differ slightly in their output formats from the existing, unchanged
3222 Python 2.6 builtins. The expected usage of the future_builtins
3223 module is:
3224 from future_builtins import hex, oct
3225
Eric Smith7ef40bf2008-02-20 23:34:22 +00003226- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3227 exponents for exponents with absolute value < 100. Follows C99
3228 standard. This is a change on Windows, which would use 3 digits.
3229 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3230 so that any alterations it does to the resulting string will be
3231 available in stringlib/formatter.h (for float.__format__).
3232
Eric Smith5a3c1352008-02-19 13:21:56 +00003233- Implemented PEP 3101, Advanced String Formatting. This adds a new
3234 builtin format(); a format() method for str and unicode; a
3235 __format__() method to object, str, unicode, int, long, float, and
3236 datetime; the class string.Formatter; and the C API
3237 PyObject_Format().
3238
Georg Brandl3ee81df2008-05-17 18:14:43 +00003239- Fixed several potential crashes, all caused by specially crafted
3240 __del__ methods exploiting objects in temporarily inconsistent
3241 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003242
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003243- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003244 prevent a possible crash: an Abstract Base Class would try to access
3245 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003246
Georg Brandl3ee81df2008-05-17 18:14:43 +00003247- Fixed repr() and str() of complex numbers with infinity or nan as
3248 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003249
Georg Brandl3ee81df2008-05-17 18:14:43 +00003250- Clear all free lists during a gc.collect() of the highest generation
3251 in order to allow pymalloc to free more arenas. Python may give back
3252 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003253
Georg Brandl3ee81df2008-05-17 18:14:43 +00003254- Issue #2045: Fix an infinite recursion triggered when printing a
3255 subclass of collections.defaultdict, if its default_factory is set
3256 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003257
Christian Heimesf75dbef2008-02-08 00:11:31 +00003258- Fixed a minor memory leak in dictobject.c. The content of the free
3259 list was not freed on interpreter shutdown.
3260
Georg Brandl3ee81df2008-05-17 18:14:43 +00003261- Limit free list of method and builtin function objects to 256
3262 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003263
Georg Brandl3ee81df2008-05-17 18:14:43 +00003264- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3265 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003266 to compact the internal free lists of pre-allocted ints and floats.
3267
Georg Brandl3ee81df2008-05-17 18:14:43 +00003268- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3269 calls. Python expected the return type int but the fork familie
3270 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003271
Georg Brandl3ee81df2008-05-17 18:14:43 +00003272- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3273 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003274
Georg Brandl3ee81df2008-05-17 18:14:43 +00003275- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3276 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003281- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3282 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003283
Georg Brandl3ee81df2008-05-17 18:14:43 +00003284- Patch #1473257: generator objects gain a gi_code attribute. This is
3285 the same object as the func_code attribute of the function that
3286 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003287
Georg Brandl3ee81df2008-05-17 18:14:43 +00003288- Issue #1920: "while 0" statements were completely removed by the
3289 compiler, even in the presence of an "else" clause, which is
3290 supposed to be run when the condition is false. Now the compiler
3291 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003292
Guido van Rossumeead05f2008-01-24 18:21:02 +00003293- A few crashers fixed: weakref_in_del.py (issue #1377858);
3294 loosing_dict_ref.py (issue #1303614, test67.py);
3295 borrowed_ref_[34].py (not in tracker).
3296
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003297- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003298 suppressed while an extension is loaded by calling SetErrorMode in
3299 dynload_win.c. The error is still reported properly.
3300
Georg Brandl3ee81df2008-05-17 18:14:43 +00003301- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003302 several extension methods and modules do not work without unicode
3303 support.
3304
Georg Brandl26543b12008-01-21 18:36:51 +00003305- Issue #1882: when compiling code from a string, encoding cookies in the
3306 second line of code were not always recognized correctly.
3307
Georg Brandl14404b62008-01-19 19:27:05 +00003308- Issue #1679: "0x" was taken as a valid integer literal.
3309
Georg Brandl6caad7d2008-01-26 14:19:22 +00003310- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003311 added.
3312
Christian Heimesc94e2b52008-01-14 04:13:37 +00003313- sys.float_info / PyFloat_GetInfo: The floating point information
3314 object was converted from a dict to a specialized structseq object.
3315
Georg Brandl3ee81df2008-05-17 18:14:43 +00003316- Patch #1816: Added sys.flags structseq. It exposes the status of
3317 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003318
Georg Brandl3ee81df2008-05-17 18:14:43 +00003319- Objects/structseq.c: Implemented new structseq representation. The
3320 patch makes structseqs (e.g. the return value of os.stat) more
3321 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003322
Georg Brandl3ee81df2008-05-17 18:14:43 +00003323- Patch #1700288: added a type attribute cache that caches method

3332 envvar and sys.dont_write_bytecode attribute. All these can be set
3333 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003334
Georg Brandl3ee81df2008-05-17 18:14:43 +00003335- Improve some exception messages when Windows fails to load an
3336 extension module. Now we get for example '%1 is not a valid Win32
3337 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003338

Christian Heimes0a8143f2007-12-18 23:22:54 +00003344- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003345 and INF. float("nan"), float("inf") and float("-inf") now work on
3346 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003347
Georg Brandl3ee81df2008-05-17 18:14:43 +00003348- Compiler now generates simpler and faster code for dictionary
3349 literals. The oparg for BUILD_MAP now indicates an estimated
3350 dictionary size. There is a new opcode, STORE_MAP, for adding
3351 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003380- Patch #1739468: Directories and zipfiles containing a __main__.py
3381 file can now be directly executed by passing their name to the
3382 interpreter. The directory/zipfile is automatically inserted as the
3383 first entry in sys.path.

3394
Georg Brandl3ee81df2008-05-17 18:14:43 +00003395- The enumerate() builtin function is no longer bounded to sequences
3396 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3397 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003398
Georg Brandl3ee81df2008-05-17 18:14:43 +00003399- Issue #1686386: Tuple's tp_repr did not take into account the
3400 possibility of having a self-referential tuple, which is possible
3401 from C code. Nor did object's tp_str consider that a type's tp_str
3402 could do something that could lead to an inifinite recursion.
3403 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3404 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003405
Georg Brandl3ee81df2008-05-17 18:14:43 +00003406- Issue #1164: It was possible to trigger deadlock when using the
3407 'print' statement to write to a file since the GIL was not released
3408 as needed. Now PyObject_Print() does the right thing along with
3409 various tp_print implementations of the built-in types and those in
3410 the collections module.

3414 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +00003419- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003420 PyObject_Call() never calling back out to Python code to trigger
3421 recursion depth updates/checks. Required the creation of a static
3422 RuntimeError instance in case normalizing an exception put the
3423 recursion check value past its limit. Fixes crashers
3424 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00003439- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003440 __*__ attributes. (Some already existed, e.g., __doc__ and
3441 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003442
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003443- Add -3 option to the interpreter to warn about features that are
3444 deprecated and will be changed/removed in Python 3.0.
3445
Georg Brandl2134e752007-05-21 20:34:16 +00003446- Patch #1686487: you can now pass any mapping after '**' in function
3447 calls.
3448
Collin Winter62903052007-05-18 23:11:24 +00003449- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003450 "except E as target:". This is to provide forwards compatibility
3451 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003452
Brett Cannon229cee22007-05-05 01:34:02 +00003453- Deprecate BaseException.message as per PEP 352.
3454
Georg Brandl3ee81df2008-05-17 18:14:43 +00003455- Issue #1303614: don't expose object's __dict__ when the dict is

3457
Vinay Sajip8549ce32007-05-06 17:53:37 +00003458- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003459 setting a plain string, ie don't expand to single letter identifiers.
3460
Raymond Hettinger13936692007-04-11 18:40:58 +00003461- Request #1191699: Slices can now be pickled.
3462
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003463- Request #1193128: str.translate() now allows a None argument for
3464 translations that only remove characters without re-mapping the
3465 remaining characters.
3466
Georg Brandl5cb76c12007-03-21 09:00:39 +00003467- Patch #1682205: a TypeError while unpacking an iterable is no longer

3469
Neal Norwitzaa754b72007-03-21 06:39:48 +00003470- Remove unused file Python/fmod.c.
3471
Guido van Rossum143b5642007-03-23 04:58:42 +00003472- Bug #1683368: The object.__init__() and object.__new__() methods are
3473 now stricter in rejecting excess arguments. The only time when
3474 either allows excess arguments is when it is not overridden and the
3475 other one is. For backwards compatibility, when both are
3476 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003477 warning later). Also, type.__init__() insists on the same signature
3478 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003479
Georg Brandl3ee81df2008-05-17 18:14:43 +00003480- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3481 object to complex using its __complex__() method before falling back
3482 to the __float__() method. Therefore, the functions in the cmath
3483 module now can operate on objects that define a __complex__()
3484 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003485
Georg Brandl3ee81df2008-05-17 18:14:43 +00003486- Patch #1623563: allow __class__ assignment for classes with
3487 __slots__. The old and the new class are still required to have the
3488 same slot names.

3494 ``object.__reduce_ex__()`` is called with an object that is faking
3495 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003496
Georg Brandl3ee81df2008-05-17 18:14:43 +00003497- Patch #1680015: Don't modify __slots__ tuple if it contains an

3501
Georg Brandl7b9c5552007-03-12 14:30:05 +00003502- Bug #1678647: write a newline after printing an exception in any
3503 case, even when converting the value to a string failed.
3504
Georg Brandl871f1bc2007-03-12 13:17:36 +00003505- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003506 its argument, if it exists. If not, it will work like before. This
3507 allows customizing the output of dir() in the presence of a
3508 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003509
Collin Winter276887b2007-03-12 16:11:39 +00003510- Patch #922167: Python no longer segfaults when faced with infinitely
3511 self-recursive reload() calls (as reported by bug #742342).
3512
Georg Brandl3ee81df2008-05-17 18:14:43 +00003513- Patch #1675981: remove unreachable code from ``type.__new__()``
3514 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003516- Patch #1491866: change the complex() constructor to allow
3517 parthensized forms. This means complex(repr(x)) now works instead of
3518 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003519
Georg Brandlaa2321b2007-03-07 00:40:28 +00003520- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003521 makes the filenames the warning module prints much more sensible
3522 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003523

3525 exception if the -i command line option or PYTHONINSPECT environment

Georg Brandl0fca97a2007-03-05 22:28:08 +00003535- Patch #1674228: when assigning a slice (old-style), check for the
3536 sq_ass_slice instead of the sq_slice slot.
3537
Georg Brandl3ee81df2008-05-17 18:14:43 +00003538- When printing an unraisable error, don't print exceptions. before
3539 the name. This duplicates the behavior whening normally printing
3540 exceptions.

Georg Brandl92a6bae2007-03-13 17:43:32 +00004107- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004108 are set for invalid interpolation sequences that would lead to

4165 TestCase and TestSuite subclasses (not instances) are no longer
4166 accepted in TestSuite.addTest(). This should cause no

4168 -- the failure just occurred later, with a more cumbersome
4169 exception.

4452 obtained from the TLS negotiation itself. Patch contributed by Bill
4453 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004454
Georg Brandl3ee81df2008-05-17 18:14:43 +00004455- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004456 that the SMTP.starttls() caller no longer needs to call ehlo()
4457 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004458 does not claim to support starttls. Adds the
4459 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00004558 time so that opening a database previously created with the DB_DUP
4559 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4560 opens. Specifically: dictionary assignment to a DB object will
4561 replace all values for a given key when the database allows
4562 duplicate values. DB users should use DB.put(k, v) when they want
4563 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004564

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004842- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004843 periodic threadstate and signal checking in tight loops. By
4844 default, this option is turned-off. It should only be enabled in
4845 debugged, performance critical applications.

4896-----
4897
Georg Brandl3ee81df2008-05-17 18:14:43 +00004898- Unified naming convention for free lists and their limits. All free
4899 lists in Object/ are named ``free_list``, the counter ``numfree``
4900 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4901 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004902
Georg Brandl3ee81df2008-05-17 18:14:43 +00004903- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4904 to ``PyTuple_SetItem``, it can be used to populate a brand new
4905 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004906

4917
Georg Brandl3ee81df2008-05-17 18:14:43 +00004918- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4919 of w# format code incorrectly truncated the length to an int, even
4920 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4921 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004922
Georg Brandl3ee81df2008-05-17 18:14:43 +00004923- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4943
4944- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4945 outside of pystate.c and should not be necessary.
4946
Georg Brandl3ee81df2008-05-17 18:14:43 +00004947- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4948 absolute imports. In earlier versions they might have used relative
4949 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004950
Georg Brandl3ee81df2008-05-17 18:14:43 +00004951- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4952 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004953
Georg Brandl3ee81df2008-05-17 18:14:43 +00004954- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004979- Removed the macfs module. It had been deprecated since Python 2.5.
4980 This lead to the deprecation of macostools.touched() as it relied
