10*Release date: XX-XXX-XXX*
11
12Core and Builtins
13-----------------
14
Antoine Pitrou1ac745b2010-07-11 12:12:00 +000015- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
16 compiler.
17
Benjamin Petersonccabcd42010-07-07 20:54:01 +000018- Issue #8413: structsequence now subclasses tuple.
19
Ezio Melotti57221d02010-07-01 07:32:02 +000020- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
21 start byte and the continuation byte(s) are now considered invalid, instead
22 of the number of bytes specified by the start byte.
23 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
24 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
25 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
26 Previous versions returned a single u'\ufffd'.
27
Mark Dickinson50b79a82010-06-30 11:13:36 +000028- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real
29 part -0.0 rather than 0.0. So "-7j" is now exactly equivalent to
30 "-(7j)".
31
Benjamin Peterson88968ad2010-06-25 19:30:21 +000032- Be more specific in error messages about positional arguments.
33
Victor Stinner4aae1eb2010-06-24 22:08:25 +000034- Issue #8949: "z" format of PyArg_Parse*() functions doesn't accept bytes
35 objects, as described in the documentation.
36
Victor Stinner0fe25a42010-06-17 23:08:50 +000037- Issue #6543: Write the traceback in the terminal encoding instead of utf-8.
Victor Stinner2cd12522010-06-17 23:17:37 +000038 Fix the encoding of the modules filename. Patch written by Amaury Forgeot
39 d'Arc.
Victor Stinner0fe25a42010-06-17 23:08:50 +000040
Mark Dickinsond35a32e2010-06-17 12:33:22 +000041- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST
42 compilation code dealing with unary minus applied to a constant.
43 The removed code was mutating the ST, causing a second compilation
44 to fail.
45
Victor Stinner554f3f02010-06-16 23:33:54 +000046- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
47 mode raises unicode errors. The encoder only supports "strict" and "replace"
48 error handlers, the decoder only supports "strict" and "ignore" error
Victor Stinner2bdab242010-06-16 23:48:49 +000049 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +000050
Victor Stinner25e8ec42010-06-25 00:02:38 +000051- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
52 "w*" format instead. Add tests for "w*" format.
53
Victor Stinner06e49dd2010-06-13 18:21:50 +000054- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
55 formats if the string contains a null byte/character. Write unit tests for
56 string formats.
57
Nick Coghlan5e76e942010-06-12 13:42:46 +000058- Issue #7490: to facilitate sharing of doctests between 2.x and 3.x test
59 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
60 location of the raised exception.
61
Victor Stinner313a1202010-06-11 23:56:51 +000062- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
63 filenames and enable os.fsencode().
64
Benjamin Peterson285a6892010-06-22 19:21:52 +000065- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
66
Antoine Pitroucc0cfd32010-06-11 21:46:32 +000067- Issue #8941: decoding big endian UTF-32 data in UCS-2 builds could crash
68 the interpreter with characters outside the Basic Multilingual Plane
69 (higher than 0x10000).
70
Mark Dickinsonc7301312010-06-10 16:05:10 +000071- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now
72 raise TypeError instead of giving a DeprecationWarning when a float
73 is parsed using the 'L' code (for long long). (All other integer
74 codes already raise TypeError in this case.)
75
Victor Stinner600d3be2010-06-10 12:00:55 +000076- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
77 enable shortcuts for upper case encoding name. Add also a shortcut for
78 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
79
Victor Stinner3dcb5ac2010-06-08 22:54:19 +000080- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
81 doesn't support "char buffer" anymore in Python3.
82
83- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
84 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
85 like bytearray.
86
Victor Stinner33109a12010-05-28 21:55:10 +000087- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
88 used anymore and it was never documented.
89
Benjamin Peterson95304522010-06-08 14:57:22 +000090- In the str.format(), raise a ValueError when indexes to arguments are too
91 large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +000092
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +000093- Issue #2844: Make int('42', n) consistently raise ValueError for
94 invalid integers n (including n = -909).
95
Mark Dickinsondc787d22010-05-23 13:33:13 +000096- Issue #8188: Introduce a new scheme for computing hashes of numbers
97 (instances of int, float, complex, decimal.Decimal and
98 fractions.Fraction) that makes it easy to maintain the invariant
99 that hash(x) == hash(y) whenever x and y have equal value.
100
Mark Dickinsoncc6a9822010-05-21 14:55:26 +0000101- Issue #8748: Fix two issues with comparisons between complex and integer
102 objects. (1) The comparison could incorrectly return True in some cases
103 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
104 (2) The comparison raised an OverflowError for large integers, leading
105 to unpredictable exceptions when combining integers and complex objects
106 in sets or dicts.
107
Victor Stinner7d79b8b2010-05-19 20:40:50 +0000108- Issue #8766: Initialize _warnings module before importing the first module.
109 Fix a crash if an empty directory called "encodings" exists in sys.path.
110
Victor Stinner9ca9c252010-05-19 16:53:30 +0000111- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
112 encoding and surrogateespace error handler instead of the locale encoding to
113 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
114
Victor Stinner372ac5e2010-05-17 01:26:01 +0000115- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace
116 (instead of strict) error handler to escape surrogates
117
Victor Stinnerae6265f2010-05-15 16:27:27 +0000118- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
119 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +0000120 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
121 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +0000122
Victor Stinner59e62db2010-05-15 13:14:32 +0000123- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
124 error handler, not only the default error handler (strict)
125
Victor Stinnerb744ba12010-05-15 12:27:16 +0000126- Issue #8610: Load file system codec at startup, and display a fatal error on
127 failure. Set the file system encoding to utf-8 (instead of None) if getting
128 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
129
Victor Stinner0964ee12010-04-30 16:48:45 +0000130- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
131 PyUnicode_FromString() to support surrogates in the filename and use the
132 right encoding
133
Georg Brandl8569e582010-05-19 20:57:08 +0000134- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
135
Victor Stinnerb9a20ad2010-04-30 16:37:52 +0000136- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler
137
Benjamin Petersonfb886362010-04-24 18:21:17 +0000138- Issue #8419: Prevent the dict constructor from accepting non-string keyword
139 arguments.
140
Victor Stinner14284c22010-04-23 12:02:30 +0000141- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
142 indirectly Python signal handlers anymore because mywrite() ignores
143 exceptions (KeyboardInterrupt)
144
Victor Stinner31be90b2010-04-22 19:38:16 +0000145- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
146 unicode string (eg. backslashreplace)
147
Victor Stinnerdcb24032010-04-22 12:08:36 +0000148- Issue #8485: PyUnicode_FSConverter() doesn't accept bytearray object anymore,
149 you have to convert your bytearray filenames to bytes
150
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +0000151- Issue #7332: Remove the 16KB stack-based buffer in
152 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
153 benefit compared to the dynamic memory allocation fallback. Patch by
154 Charles-François Natali.
155
Benjamin Peterson8380dd52010-04-16 22:51:37 +0000156- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
157 passed to bytes or bytearray.
158
Philip Jenvey0805ca32010-04-07 04:04:10 +0000159- Issue #7301: Add environment variable $PYTHONWARNINGS.
160
Benjamin Petersond856ab62010-04-06 21:55:16 +0000161- Issue #8329: Don't return the same lists from select.select when no fds are
162 changed.
163
Mark Dickinson3318d292010-04-06 16:53:17 +0000164- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
165 on 64-bit machines. The shift count for either left or right shift is
166 permitted to be up to sys.maxsize.
167
Benjamin Peterson8daa49e2010-04-03 22:55:48 +0000168- Ensure that tokenization of identifiers is not affected by locale.

175 case it is set.
Victor Stinner00d6a1d2010-03-25 01:02:29 +0000176
Victor Stinner120c2122010-03-25 00:30:28 +0000177- Issue #8226: sys.setfilesystemencoding() raises a LookupError if the encoding
178 is unknown
179

181
Mark Dickinsond59b4162010-03-13 11:34:40 +0000182- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
183 PyMemberDefs could produce an internal error; raise TypeError instead.
184
Mark Dickinsonf673f0c2010-03-13 09:48:39 +0000185- Issue #7845: Rich comparison methods on the complex type now return
186 NotImplemented rather than raising a TypeError when comparing with an
187 incompatible type; this allows user-defined classes to implement their own
188 comparisons with complex.
189
Victor Stinner52f6dd72010-03-12 14:45:56 +0000190- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
191 (SIGINT). If an error occurs while importing the site module, the error is
192 printed and Python exits. Initialize the GIL before importing the site
193 module.
194
Benjamin Petersonae5f2f42010-03-07 17:10:51 +0000195- Issue #7173: Generator finalization could invalidate sys.exc_info().

198 a fatal error in low memory condition.
199
Victor Stinner6aa278e2010-03-03 00:18:49 +0000200- Issue #7820: The parser tokenizer restores all bytes in the right if
201 the BOM check fails.
202
Benjamin Peterson23e018a2010-02-27 17:40:01 +0000203- Handle errors from looking up __prepare__ correctly.
204
Larry Hastings1373a072010-02-24 22:49:58 +0000205- Issue #5939: Add additional runtime checking to ensure a valid capsule
206 in Modules/_ctypes/callproc.c.
207

209 UnicodeEncodeError, UnicodeDecodeError, and UnicodeTranslateError to
210 strings.
211
Eric Smithabb28c62010-02-23 00:22:24 +0000212- Issue #6902: Fix problem with built-in types format incorrectly with

221 deprecations.
222
Antoine Pitrou05b7c562010-02-02 22:47:00 +0000223- Issue #7385: Fix a crash in `MemoryView_FromObject` when
224 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
225
Mark Dickinsonbc099642010-01-29 17:27:24 +0000226- Issue #7788: Fix an interpreter crash produced by deleting a list
227 slice with very large step value.
228
Eric Smithf7bb5782010-01-27 00:44:57 +0000229- Issue #7766: Change sys.getwindowsversion() return value to a named
230 tuple and add the additional members returned in an OSVERSIONINFOEX
231 structure. The new members are service_pack_major, service_pack_minor,
232 suite_mask, and product_type.
233
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000234- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
235 could crash in many places because of the PyByteArray_AS_STRING() macro
236 returning NULL. The macro now returns a statically allocated empty
237 string instead.
238
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000239- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
240 where the right hand operand is a set of constants, by turning the set into
241 a frozenset and pre-building it as a constant. The comparison operation
242 is made against the constant instead of building a new set each time it is
243 executed (a similar optimization already existed which turned a list of
244 constants into a pre-built tuple). Patch and additional tests by Dave
245 Malcolm.
246
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000247- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
248 methods of bytes, bytearray and unicode objects by using a common
249 implementation based on stringlib's fast search. Patch by Florent Xicluna.
250
Mark Dickinson45b63652010-01-16 18:10:25 +0000251- Issue #7632: Fix various str -> float conversion bugs present in 2.7
252 alpha 2, including: (1) a serious 'wrong output' bug that could
253 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
254 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000255 strings corresponding to subnormal values, (3) a memory leak for
256 some values large enough to cause overflow, and (4) a number of
257 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000258
Benjamin Petersonaea44282010-01-04 01:10:28 +0000259- The __complex__ method is now looked up on the class of instances to make it
260 consistent with other special methods.

269 negative zero) in ** operator. The behaviour now conforms to that
270 described in C99 Annex F.
271
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000272- Issue #1811: improve accuracy and cross-platform consistency for
273 true division of integers: the result of a/b is now correctly
274 rounded for ints a and b (at least on IEEE 754 platforms), and in
275 particular does not depend on the internal representation of an int.
276
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000277- Issue #6834: replace the implementation for the 'python' and 'pythonw'
278 executables on OSX.
279
280 These executables now work properly with the arch(1) command:
281 ``arch -ppc python`` will start a universal binary version of python
282 in PPC mode (unlike previous releases).
283
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000284- Issue #7466: segmentation fault when the garbage collector is called
285 in the middle of populating a tuple. Patch by Florent Xicluna.
286
Amaury Forgeot d'Arc64f3ca42009-12-01 21:59:18 +0000287- Issue #7419: setlocale() could crash the interpreter on Windows when called
288 with invalid values.
289
Amaury Forgeot d'Arc7d0bddd2009-11-30 00:08:56 +0000290- Issue #6077: On Windows, files opened with tempfile.TemporaryFile in "wt+"
291 mode would appear truncated on the first '0x1a' byte (aka. Ctrl+Z).
292
Ronald Oussoren3c1928a2009-11-19 17:15:31 +0000293- Issue #7085: Fix crash when importing some extensions in a thread

300
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000301- Issue #7298: fixes for range and reversed(range(...)). Iteration
302 over range(a, b, c) incorrectly gave an empty iterator when a, b and
303 c fit in C long but the length of the range did not. Also fix
304 several cases where reversed(range(a, b, c)) gave wrong results, and
305 fix a refleak for reversed(range(a, b, c)) with large arguments.
306
Raymond Hettingerfc438512009-11-01 20:55:33 +0000307- Issue #7244: itertools.izip_longest() no longer ignores exceptions

714
Mark Dickinsonc69160e2010-05-04 14:35:33 +0000715- Issue #8567: Fix precedence of signals in Decimal module: when a
716 Decimal operation raises multiple signals and more than one of those
717 signals is trapped, the specification determines the order in which
718 the signals should be handled. In many cases this order wasn't
719 being followed, leading to the wrong Python exception being raised.

751 and mappings.
752
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000753- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
754 where the method could block indefinitely if called just before the
755 event loop started running. This also fixes the occasional freezes
756 witnessed in test_httpservers.
757
Antoine Pitrou40f08742010-04-24 22:04:40 +0000758- Issue #8524: When creating an SSL socket, the timeout value of the
759 original socket wasn't retained (instead, a socket with a positive timeout
760 would be turned into a non-blocking SSL socket).
761
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000762- Issue #5103: SSL handshake would ignore the socket timeout and block
763 indefinitely if the other end didn't respond.
764
765- The do_handshake() method of SSL objects now adjusts the blocking mode of
766 the SSL structure if necessary (as other methods already do).
767
Victor Stinner13bb71c2010-04-23 21:41:56 +0000768- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates

779 and keywords.
780
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000781- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
782 a non-infinite timeout. Also make that method friendlier with applications
783 wanting to continue using the socket in clear-text mode, by disabling
784 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
785
Antoine Pitrou7062db82010-04-22 13:30:10 +0000786- Issue #8496: make mailcap.lookup() always return a list, rather than an

794 doesn't fail because of an "unknown algorithm".
795
Tarek Ziadéfb437512010-04-20 08:57:33 +0000796- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.

805
Ronald Oussoren84151202010-04-18 20:46:11 +0000806- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
807 (as long as the user didn't specify 'automatic proxy configuration').
808
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000809- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response

834
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000835- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
836 module now takes an optional timeout argument in seconds. Timeout support
837 relies on the system threading library, so as to avoid a semi-busy wait
838 loop.
839
Victor Stinner485fb562010-04-13 11:07:24 +0000840- Issue #8383: pickle and pickletools use surrogatepass error handler when

842 Python 2.x and 3.0
843
R. David Murrayb2416e52010-04-12 16:58:02 +0000844- Issue #7585: difflib context and unified diffs now place a tab between
845 filename and date, conforming to the 'standards' they were originally
846 designed to follow. This improves compatibility with patch tools.
847
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000848- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
849 character sets will now consistently use a Content-Transfer-Encoding of
850 7bit rather than sometimes being marked as 8bit.
851
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000852- Issue #8375: test_distutils now checks if the temporary directory are still
853 present before it cleans them.
854

859 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
860 and `ssl.OPENSSL_VERSION_NUMBER`.
861
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000862- Add functools.total_ordering() and functools.cmp_to_key().
863
Mark Dickinson089b00c2010-04-03 15:51:03 +0000864- Issue #8257: The Decimal construct now accepts a float instance
865 directly, converting that float to a Decimal of equal value:
866
867 >>> Decimal(1.1)
868 Decimal('1.100000000000000088817841970012523233890533447265625')
869
Mark Dickinson98127c32010-04-03 11:18:52 +0000870- Issue #8294: The Fraction constructor now accepts Decimal and float
871 instances directly.
872
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000873- Issue #7279: Comparisons involving a Decimal signaling NaN now
874 signal InvalidOperation instead of returning False. (Comparisons
875 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
876 are now hashable; Decimal signaling NaNs remain unhashable.
877
878- Issue #2531: Comparison operations between floats and Decimal
879 instances now return a result based on the numeric values of the
880 operands; previously they returned an arbitrary result based on
Mark Dickinson08ade6f2010-06-11 10:44:52 +0000881 the relative ordering of id(float) and id(Decimal). See also
Mark Dickinson9b88b912010-06-11 10:46:57 +0000882 issue #8188, which adds Decimal-to-Fraction comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000883
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000884- Added a subtract() method to collections.Counter().
885
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000886- Issue #8233: When run as a script, py_compile.py optionally takes a single
887 argument `-` which tells it to read files to compile from stdin. Each line
888 is read on demand and the named file is compiled immediately. (Original
889 patch by Piotr Ożarowski).
890
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000891- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
892 form feed (0x0C) are now considered linebreaks, as specified in Unicode
893 Standard Annex #14. See issue #7643.
894 http://www.unicode.org/reports/tr14/
895
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000896- Comparisons using one of <, <=, >, >= between a complex instance and
897 a Fractions instance now raise TypeError instead of returning
898 True/False. This makes Fraction <=> complex comparisons consistent with
899 int <=> complex, float <=> complex, and complex <=> complex comparisons.

Nick Coghlan260bd3e2009-11-16 06:49:25 +00001209- Issue #6816: runpy now provides a run_path function that allows Python code
1210 to execute file paths that refer to source or compiled Python files as well
1211 as zipfiles, directories and other valid sys.path entries that contain a
1212 __main__.py file. This allows applications that run other Python scripts to
1213 support the same flexibility as the CPython command line itself.

Victor Stinnere125f132010-05-15 21:04:43 +00001232 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +00001233 recursive locks as fast as regular non-recursive locks (previously,
1234 they were slower by 10x to 15x).

1254 reading from stdin so that existing input does not confuse it and
1255 lead to incorrect entry or an IOError. It also properly flushes it
1256 afterwards to avoid the terminal echoing the input afterwards on
1257 OSes such as Solaris.

1471 ``%z`` directive. When the ``%z`` directive is present in the
1472 format string, an aware ``datetime`` object is returned with
1473 ``tzinfo`` bound to a ``datetime.timezone`` instance constructed
1474 from the parsed offset. If both ``%z`` and ``%Z`` are present, the
1475 data in ``%Z`` field is used for timezone name, but ``%Z`` data
1476 without ``%z`` is discarded.
1477
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00001478- Issue #5094: The ``datetime`` module now has a simple concrete class
1479 implementing ``datetime.tzinfo`` interface. Instances of the new
1480 class, ``datetime.timezone``, return fixed name and UTC offset from
1481 their ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)``
1482 method always returns ``None``. A class attribute, ``utc`` contains
1483 an instance representing the UTC timezone. Original patch by Rafe
1484 Kaplan.

Mark Dickinson4b80ef52010-06-12 15:17:02 +00001486- Issue #8973: Add __all__ to struct module; this ensures that

Stefan Kraha3ac44e2010-06-08 14:00:52 +00001493- Issue #7384: If the system readline library is linked against ncurses,
1494 the curses module must be linked against ncurses as well. Otherwise it
1495 is not safe to load both the readline and curses modules in an application.

1501 algorithm with an improved 'binary-split' algorithm that uses fewer
1502 multiplications and allows many of the multiplications to be
1503 performed using plain C integer arithmetic instead of PyLong
1504 arithmetic. Also uses a lookup table for small arguments.

1508
Mark Dickinson0381e3f2010-05-08 14:35:02 +00001509- Issue #8644: The accuracy of td.total_seconds() has been improved (by

1511 the result is now always correctly rounded, and is equivalent to td /
1512 timedelta(seconds=1).

Mark Dickinsonc5935772010-04-03 15:54:36 +00001520- Issue #8300: When passing a non-integer argument to struct.pack with any
1521 integer format code, struct.pack first attempts to convert the non-integer
1522 using its __index__ method. If that method is non-existent or raises
1523 TypeError it goes on to try the __int__ method, as described below.

1742 now also used by regrtest to run all the tests in a temporary directory.
1743 The original CWD is saved in `support.SAVEDCWD`.
1744 Thanks to Florent Xicluna who helped with the patch.

1757
R. David Murray596da442009-12-14 23:06:11 +00001758- Issue #7498: test_multiprocessing now uses test.support.find_unused_port
R. David Murray83396232009-12-14 22:45:15 +00001759 instead of a hardcoded port number in test_rapid_restart.

Victor Stinnere125f132010-05-15 21:04:43 +00001761- Issue #7431: use TESTFN in test_linecache instead of trying to create a
R. David Murrayba311052009-12-04 00:09:14 +00001762 file in the Lib/test directory, which might be read-only for the
1763 user running the tests.
1764
R. David Murray35768ad2009-11-15 00:23:21 +00001765- Issue #7324: add a sanity check to regrtest argument parsing to
1766 catch the case of an option with no handler.
1767
R. David Murray7dc72cc2009-11-14 16:13:02 +00001768- Issue #7312: Add a -F flag to run the selected tests in a loop until
1769 a test fails. Can be combined with -j.
1770
Antoine Pitrou060cee22009-11-13 16:29:04 +00001771- Issue #6551: test_zipimport could import and then destroy some modules of
1772 the encodings package, which would make other tests fail further down
1773 the road because the internally cached encoders and decoders would point
1774 to empty global variables.
1775
Antoine Pitrou941ee882009-11-11 20:59:38 +00001776- Issue #7295: Do not use a hardcoded file name in test_tarfile.

1782 tests instead of tempfile.tempdir. This prevents the tests from sharing state
1783 between concurrent executions on the same system.
1784
Brett Cannon0ae45112009-11-05 01:17:22 +00001785- Issue #7248: In importlib.test.source.util a try/finally block did not make

1787 calling methods on the object.
1788
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001789- Issue #7222: Make thread "reaping" more reliable so that reference
1790 leak-chasing test runs give sensible results. The previous method of
1791 reaping threads could return successfully while some Thread objects were
1792 still referenced. This also introduces a new private function:
1793 :func:`_thread._count()`.
1794
R. David Murray27144602009-10-19 15:26:16 +00001795- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1796 longer runs the risk of causing the worker thread to fail.
1797
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001798- Issue #7055: test___all__ now greedily detects all modules which have an
1799 __all__ attribute, rather than using a hardcoded and incomplete list.
1800
R. David Murray0bc11ae2009-10-18 22:18:17 +00001801- Issue #7058: Added save/restore for things like sys.argv and cwd to
1802 runtest_inner in regrtest, with warnings if the called test modifies them,
1803 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001804
Mark Dickinson2e304402009-10-04 18:43:54 +00001805- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1806
Brett Cannon3c273842009-07-20 00:14:29 +00001807- Fixed tests in importlib.test.source.test_abc_loader that were masking
1808 the proper exceptions that should be raised for missing or improper code
1809 object bytecode.
1810
Brett Cannonb49c70c2009-07-15 04:08:33 +00001811- Removed importlib's custom test discovery code and switched to
1812 unittest.TestLoader.discover().

R. David Murray74b89242009-05-13 17:33:03 +00002033- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
2034 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
2035 corrects a pydoc regression.
2036
R. David Murray99352742009-05-07 18:24:38 +00002037- Issue 5955: aifc's close method did not close the file it wrapped,
2038 now it does. This also means getfp method now returns the real fp.

2077================================
2078
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00002079*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00002080
2081Core and Builtins
2082-----------------
2083
Mark Dickinson865e01a2009-05-07 16:37:01 +00002084- Issue #5914: Add new C API function PyOS_string_to_double, and
2085 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
2086
Eric Smith741191f2009-05-06 13:08:15 +00002087- Issue #3382: float.__format__, complex.__format__, and %-formatting
2088 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
2089 affects nan -> NAN and inf -> INF.
2090
Mark Hammond5a607a32009-05-06 08:04:54 +00002091- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
2092 in all operations, including splitdrive, split, etc. splitunc() now issues
2093 a PendingDeprecation warning.
2094
Eric Smith63376222009-05-05 14:04:18 +00002095- Issue #5920: For float.__format__, change the behavior with the
2096 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
2097 to be like 'g' but with at least one decimal point and with a
2098 default precision of 12. Previously, the behavior the same but with
2099 a default precision of 6. This more closely matches str(), and
2100 reduces surprises when adding alignment flags to the empty
2101 presentation type. This also affects the new complex.__format__ in
2102 the same way.
2103
Martin v. Löwis011e8422009-05-05 04:43:17 +00002104- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
2105
R. David Murrayb18500d2009-05-04 22:59:07 +00002106- Issue #5890: in subclasses of 'property' the __doc__ attribute was
2107 shadowed by classtype's, even if it was None. property now
2108 inserts the __doc__ into the subclass instance __dict__.
2109
Antoine Pitrou244651a2009-05-04 18:56:13 +00002110- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
2111 sequences. Patch by Nick Barnes and Victor Stinner.
2112
Martin v. Löwise0a2b722009-05-10 08:08:56 +00002113- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00002114
Benjamin Petersond2e0c792009-05-01 20:40:59 +00002115- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
2116 received a new method, detach(). detach() disconnects the underlying stream
2117 from the buffer or text IO and returns it.
2118
Mark Dickinson33841c32009-05-01 15:37:04 +00002119- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
2120 floats with absolute value over 1e50. Also remove length
2121 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
2122 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00002123
Eric Smith741191f2009-05-06 13:08:15 +00002124- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00002125 format(complex(1, 2./3), '.5') now produces a sensible result.
2126
Mark Dickinsond3ca5572009-04-29 18:47:07 +00002127- Issue #5864: Fix empty format code formatting for floats so that it
2128 never gives more than the requested number of significant digits.
2129
Eric Smith6dc46f52009-04-27 20:39:49 +00002130- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
2131 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
2132
Eric Smithcc32a112009-04-26 21:35:14 +00002133- Issue #5835: Deprecate PyOS_ascii_formatd.
2134
Martin v. Löwis71efeb72009-04-26 01:02:07 +00002135- Issue #4971: Fix titlecase for characters that are their own
2136 titlecase, but not their own uppercase.
2137
Benjamin Peterson193152c2009-04-25 01:08:45 +00002138- Issue #5283: Setting __class__ in __del__ caused a segfault.
2139
Mark Dickinsonad476da2009-04-23 19:14:16 +00002140- Issue #5816: complex(repr(z)) now recovers z exactly, even when
2141 z involves nans, infs or negative zeros.
2142
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00002143- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00002144
Mark Dickinsone6a076d2009-04-18 11:48:33 +00002145- Issue #1869 (and many duplicates): make round(x, n) correctly
2146 rounded for a float x, by using the decimal <-> binary conversions
2147 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2148 consistently agrees with format(x, '.2f').
2149
Benjamin Petersonae937c02009-04-18 20:54:08 +00002150- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
2151 some builtin types.
2152
Eric Smith0923d1d2009-04-16 20:16:10 +00002153- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
2154
Eric Smith35e84722009-04-16 20:21:28 +00002155- Issue #5515: str.format() type 'n' combined with commas and leading
2156 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002157
2158- Implement PEP 378, Format Specifier for Thousands Separator, for
2159 floats.
2160
Mark Dickinson3370cce2009-04-17 22:40:53 +00002161- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002162 1e11, not 1e12. This avoids printing 13 significant digits in
2163 situations where only 12 of them are correct. Example problem
2164 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2165 long time.)
2166
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002167- Issue #1580: On most platforms, use a 'short' float repr: for a
2168 finite float x, repr(x) now outputs a string based on the shortest
2169 sequence of decimal digits that rounds to x. Previous behaviour was
2170 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002171 Another minor difference is that the new repr switches to
2172 exponential notation at 1e16 instead of the previous 1e17; this
2173 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002174
2175 There's a new sys attribute sys.float_repr_style, which takes
2176 the value 'short' to indicate that we're using short float repr,
2177 and 'legacy' if the short float repr isn't available for one
2178 reason or another.
2179
2180 The float repr change involves incorporating David Gay's 'perfect
2181 rounding' code into the Python core (it's in Python/dtoa.c). As a
2182 secondary consequence, all string-to-float and float-to-string
2183 conversions (including all float formatting operations) will be
2184 correctly rounded on these platforms.
2185
2186 See issue 1580 discussions for details of platforms for which
2187 this change does not apply.
2188
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002189- Issue #5759: float() didn't call __float__ on str subclasses.
2190
Georg Brandlabc38772009-04-12 15:51:51 +00002191- The string.maketrans() function is deprecated; there is a new static method
2192 maketrans() on the bytes and bytearray classes. This removes confusion about
2193 the types string.maketrans() is supposed to work with, and mirrors the
2194 methods available on the str class.
2195
R. David Murraydc6da8a2009-04-09 22:16:43 +00002196- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
2197 its clarity and its speed.
2198
Matthias Klose091c7b12009-04-07 13:24:27 +00002199- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
2200 to avoid compiler warnings.
2201
Walter Dörwald8dc33d52009-05-06 14:41:26 +00002202- Issue #3739: The unicode-internal encoder now reports the number of characters
2203 consumed like any other encoder (instead of the number of bytes).

Benjamin Peterson8f76b492009-04-03 22:22:42 +00002340- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
2341
Benjamin Peterson7fe98532009-04-02 00:33:55 +00002342- Issue #5499: The 'c' code for argument parsing functions now only accepts a
2343 byte, and the 'C' code only accepts a unicode character.
2344
Georg Brandl406b3d82009-04-11 21:24:37 +00002345- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
2346 when hitting the recursion limit under certain circumstances.
2347
Brett Cannon0759dd62009-04-01 18:13:07 +00002348- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
2349
Georg Brandlab6f2f62009-03-31 04:16:10 +00002350- Fix a segfault when running test_exceptions with coverage, caused by
2351 insufficient checks in accessors of Exception.__context__.
2352
Guido van Rossum0ad59d42009-03-30 22:01:35 +00002353- Issue #5604: non-ASCII characters in module name passed to
2354 imp.find_module() were converted to UTF-8 while the path is
2355 converted to the default filesystem encoding, causing nonsense.
2356
Benjamin Peterson09832742009-03-26 17:15:46 +00002357- Issue #5126: str.isprintable() returned False for space characters.
2358
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00002359- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
2360 the end sys.path, for compatibility with the system install of Python.
2361
Antoine Pitrou3a652b12009-03-23 18:52:06 +00002362- Issue #4688: Add a heuristic so that tuples and dicts containing only
2363 untrackable objects are not tracked by the garbage collector. This can
2364 reduce the size of collections and therefore the garbage collection overhead
2365 on long-running programs, depending on their particular use of datatypes.
2366
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00002367- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

2370
Mark Dickinsonbd792642009-03-18 20:06:12 +00002371- Issue #4258: Make it possible to use base 2**30 instead of base
2372 2**15 for the internal representation of integers, for performance
2373 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
2374 --enable-big-digits option to configure, which overrides the
2375 default. Add sys.int_info structseq to provide information about
2376 the internal format.
2377
Mark Dickinson081dfee2009-03-18 14:47:41 +00002378- Issue #4474: PyUnicode_FromWideChar now converts characters outside
2379 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
2380 and sizeof(Py_UNICODE) == 2.
2381
Eric Smith8ec90442009-03-14 12:29:34 +00002382- Issue #5237: Allow auto-numbered fields in str.format(). For

2384
Antoine Pitrou652e7072009-03-13 19:25:20 +00002385- Issue #5392: when a very low recursion limit was set, the interpreter would
2386 abort with a fatal error after the recursion limit was hit twice.
2387
Matthias Klose042f1332009-04-04 14:32:42 +00002388- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

2419
Brett Cannon7f6b4f82009-03-30 21:30:26 +00002420- Issue #5236: Change time.strptime() to only take strings. Didn't work with
2421 bytes already but the failure was non-obvious.
2422
Jesse Noller7af4ef82009-03-30 16:47:15 +00002423- Issue #5177: Multiprocessing's SocketListener class now uses

2434
Lars Gustäbel42e00912009-03-22 20:34:29 +00002435- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
2436 forever on incomplete input. That caused tarfile.open() to hang when used
2437 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
2438 partial bzip2 compressed data.
2439
Mark Dickinson79f52032009-03-17 23:12:51 +00002440- Issue #2110: Add support for thousands separator and 'n' type

2458 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00002459 struct.error instead of returning b'\xff\xff\xff\xff'. The
2460 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants

Mark Dickinson87ec0852009-02-09 17:15:59 +00002488- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2489 it now forces its argument to double before testing for infinity.
2490
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002491- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
2492 returns a non-number type.
2493

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002500
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002501- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002502 were suppressing all exceptions. These include list() and bytearray().
2503
Mark Dickinson1124e712009-01-28 21:25:58 +00002504- Issue #4707: round(x, n) now returns an integer if x is an integer.
2505 Previously it returned a float.
2506
Antoine Pitroub52ec782009-01-25 16:34:23 +00002507- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2508 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2509 evaluation loop is compiled with a new dispatch mechanism which gives
2510 speedups of up to 20%, depending on the system, on various benchmarks.
2511
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002512- Issue #4874: Most builtin decoders now reject unicode input.

2520 optional module state data.
2521
Mark Dickinson8055afd2009-01-17 10:04:45 +00002522- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2523 type to (void *).
2524
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002525- Issue #4935: The overflow checking code in the expandtabs() method common
2526 to str, bytes and bytearray could be optimized away by the compiler, letting
2527 the interpreter segfault instead of raising an error.
2528
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002529- Issue #3720: Fix a crash when an iterator modifies its class and removes its

2541 common cases are optimized thanks to a dedicated fast path and a moderate
2542 amount of loop unrolling.
2543
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002544- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2545 collecting the oldest generation) so that allocating lots of objects without
2546 destroying them does not show quadratic performance. Based on a proposal by
2547 Martin von Löwis at
2548 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2549
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002550- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002551 having been closed (for instance, a read() call could return some
2552 previously buffered data). Patch by Dmitry Vasiliev.
2553
Antoine Pitrou05608432009-01-09 18:53:14 +00002554- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2555 flag to work properly. Furthermore, when specifying -u, the text stdout
2556 and stderr streams have line-by-line buffering enabled (the default being
2557 to buffer arbitrary chunks of data).
2558
Raymond Hettinger35631532009-01-09 03:58:09 +00002559- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2560 instead of ints (reducing its size from 4 to 8 times thereby reducing
2561 Python's overall memory).
2562
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002563- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2564 an existing .py counterpart, override the co_filename attributes of all
2565 code objects if the original filename is obsolete (which can happen if the
2566 file has been renamed, moved, or if it is accessed through different paths).
2567 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2568
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002569- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2570 one byte. Also fixes the meaning of len() so that it returns the number of
2571 items, rather than the size in bytes.
2572
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002573- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2574
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002575- Issue #4747: When the terminal does not use utf-8, executing a script with
2576 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2577
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002578- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002580
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002581- Issue #3680: Reference cycles created through a dict, set or deque iterator
2582 did not get collected.
2583
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002584- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2585 where the tp_hash and tp_dict slots are both NULL.
2586
Georg Brandlccc47b62008-12-28 11:44:14 +00002587- Issue #4759: None is now allowed as the first argument of
2588 bytearray.translate(). It was always allowed for bytes.translate().
2589
Skip Montanaro80072cb2008-12-23 03:51:14 +00002590- Added test case to ensure attempts to read from a file opened for writing
2591 fail.

2597
Antoine Pitrou621601a2008-12-17 23:18:19 +00002598- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2599 print elapsed times, not only when some objects are uncollectable /
2600 unreachable. Original patch by Neil Schemenauer.
2601
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002602- Issue #3439: Add a bit_length method to int.
2603
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002604- Issue #2173: When getting device encoding, check that return value of
2605 nl_langinfo is not the empty string. This was causing silent build
2606 failures on OS X.
2607
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002608- Issue #4597: Fixed several opcodes that weren't always propagating
2609 exceptions.
2610
2611- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002612 context manager returns a value that cannot be converted to a bool.
2613
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002614- Issue #4445: Replace "sizeof(PyBytesObject)" with
2615 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2616 bytes instances. On a typical machine this saves 3 bytes of memory
2617 (on average) per allocation of a bytes instance.

Antoine Pitrou08838b62009-01-21 00:55:13 +00002961- Issue #5008: When a file is opened in append mode with the new IO library,
2962 do an explicit seek to the end of file (so that e.g. tell() returns the

Vinay Sajipad5fa2f2009-04-27 13:55:05 +00003252 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00003253 from test support, which does the conversion.
