11
12Core and Builtins
13-----------------
14
Victor Stinner8182b712010-07-28 00:40:58 +000015- Issue #8991: convertbuffer() rejects discontigious buffers.
16
Antoine Pitrou1ac745b2010-07-11 12:12:00 +000017- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
18 compiler.
19
Benjamin Petersonccabcd42010-07-07 20:54:01 +000020- Issue #8413: structsequence now subclasses tuple.
21
Ezio Melotti57221d02010-07-01 07:32:02 +000022- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
23 start byte and the continuation byte(s) are now considered invalid, instead
24 of the number of bytes specified by the start byte.
25 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
26 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
27 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
28 Previous versions returned a single u'\ufffd'.
29
Mark Dickinson50b79a82010-06-30 11:13:36 +000030- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real
31 part -0.0 rather than 0.0. So "-7j" is now exactly equivalent to
32 "-(7j)".
33
Benjamin Peterson88968ad2010-06-25 19:30:21 +000034- Be more specific in error messages about positional arguments.
35
Victor Stinner4aae1eb2010-06-24 22:08:25 +000036- Issue #8949: "z" format of PyArg_Parse*() functions doesn't accept bytes
37 objects, as described in the documentation.
38
Victor Stinner0fe25a42010-06-17 23:08:50 +000039- Issue #6543: Write the traceback in the terminal encoding instead of utf-8.
Victor Stinner2cd12522010-06-17 23:17:37 +000040 Fix the encoding of the modules filename. Patch written by Amaury Forgeot
41 d'Arc.
Victor Stinner0fe25a42010-06-17 23:08:50 +000042
Mark Dickinsond35a32e2010-06-17 12:33:22 +000043- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST
44 compilation code dealing with unary minus applied to a constant.
45 The removed code was mutating the ST, causing a second compilation
46 to fail.
47
Victor Stinner554f3f02010-06-16 23:33:54 +000048- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
49 mode raises unicode errors. The encoder only supports "strict" and "replace"
50 error handlers, the decoder only supports "strict" and "ignore" error
Victor Stinner2bdab242010-06-16 23:48:49 +000051 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +000052
Victor Stinner25e8ec42010-06-25 00:02:38 +000053- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
54 "w*" format instead. Add tests for "w*" format.
55
Victor Stinner06e49dd2010-06-13 18:21:50 +000056- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
57 formats if the string contains a null byte/character. Write unit tests for
58 string formats.
59
Nick Coghlan5e76e942010-06-12 13:42:46 +000060- Issue #7490: to facilitate sharing of doctests between 2.x and 3.x test
61 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
62 location of the raised exception.
63
Victor Stinner313a1202010-06-11 23:56:51 +000064- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
65 filenames and enable os.fsencode().
66
Benjamin Peterson285a6892010-06-22 19:21:52 +000067- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
68
Antoine Pitroucc0cfd32010-06-11 21:46:32 +000069- Issue #8941: decoding big endian UTF-32 data in UCS-2 builds could crash
70 the interpreter with characters outside the Basic Multilingual Plane
71 (higher than 0x10000).
72
Mark Dickinsonc7301312010-06-10 16:05:10 +000073- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now
74 raise TypeError instead of giving a DeprecationWarning when a float
75 is parsed using the 'L' code (for long long). (All other integer
76 codes already raise TypeError in this case.)
77
Victor Stinner600d3be2010-06-10 12:00:55 +000078- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
79 enable shortcuts for upper case encoding name. Add also a shortcut for
80 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
81
Victor Stinner3dcb5ac2010-06-08 22:54:19 +000082- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
83 doesn't support "char buffer" anymore in Python3.
84
85- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
86 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
87 like bytearray.
88
Victor Stinner33109a12010-05-28 21:55:10 +000089- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
90 used anymore and it was never documented.
91
Benjamin Peterson95304522010-06-08 14:57:22 +000092- In the str.format(), raise a ValueError when indexes to arguments are too
93 large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +000094
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +000095- Issue #2844: Make int('42', n) consistently raise ValueError for
96 invalid integers n (including n = -909).
97
Mark Dickinsondc787d22010-05-23 13:33:13 +000098- Issue #8188: Introduce a new scheme for computing hashes of numbers
99 (instances of int, float, complex, decimal.Decimal and
100 fractions.Fraction) that makes it easy to maintain the invariant
101 that hash(x) == hash(y) whenever x and y have equal value.
102
Mark Dickinsoncc6a9822010-05-21 14:55:26 +0000103- Issue #8748: Fix two issues with comparisons between complex and integer
104 objects. (1) The comparison could incorrectly return True in some cases
105 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
106 (2) The comparison raised an OverflowError for large integers, leading
107 to unpredictable exceptions when combining integers and complex objects
108 in sets or dicts.
109
Victor Stinner7d79b8b2010-05-19 20:40:50 +0000110- Issue #8766: Initialize _warnings module before importing the first module.
111 Fix a crash if an empty directory called "encodings" exists in sys.path.
112
Victor Stinner9ca9c252010-05-19 16:53:30 +0000113- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
114 encoding and surrogateespace error handler instead of the locale encoding to
115 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
116
Victor Stinner372ac5e2010-05-17 01:26:01 +0000117- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace
118 (instead of strict) error handler to escape surrogates
119
Victor Stinnerae6265f2010-05-15 16:27:27 +0000120- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
121 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +0000122 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
123 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +0000124
Victor Stinner59e62db2010-05-15 13:14:32 +0000125- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
126 error handler, not only the default error handler (strict)
127
Victor Stinnerb744ba12010-05-15 12:27:16 +0000128- Issue #8610: Load file system codec at startup, and display a fatal error on
129 failure. Set the file system encoding to utf-8 (instead of None) if getting
130 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
131
Victor Stinner0964ee12010-04-30 16:48:45 +0000132- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
133 PyUnicode_FromString() to support surrogates in the filename and use the
134 right encoding
135
Georg Brandl8569e582010-05-19 20:57:08 +0000136- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
137
Victor Stinnerb9a20ad2010-04-30 16:37:52 +0000138- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler
139
Benjamin Petersonfb886362010-04-24 18:21:17 +0000140- Issue #8419: Prevent the dict constructor from accepting non-string keyword
141 arguments.
142
Victor Stinner14284c22010-04-23 12:02:30 +0000143- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
144 indirectly Python signal handlers anymore because mywrite() ignores
145 exceptions (KeyboardInterrupt)
146
Victor Stinner31be90b2010-04-22 19:38:16 +0000147- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
148 unicode string (eg. backslashreplace)
149
Victor Stinnerdcb24032010-04-22 12:08:36 +0000150- Issue #8485: PyUnicode_FSConverter() doesn't accept bytearray object anymore,
151 you have to convert your bytearray filenames to bytes
152
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +0000153- Issue #7332: Remove the 16KB stack-based buffer in
154 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
155 benefit compared to the dynamic memory allocation fallback. Patch by
156 Charles-François Natali.
157
Benjamin Peterson8380dd52010-04-16 22:51:37 +0000158- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
159 passed to bytes or bytearray.
160
Philip Jenvey0805ca32010-04-07 04:04:10 +0000161- Issue #7301: Add environment variable $PYTHONWARNINGS.
162
Benjamin Petersond856ab62010-04-06 21:55:16 +0000163- Issue #8329: Don't return the same lists from select.select when no fds are
164 changed.
165
Mark Dickinson3318d292010-04-06 16:53:17 +0000166- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
167 on 64-bit machines. The shift count for either left or right shift is
168 permitted to be up to sys.maxsize.
169
Benjamin Peterson8daa49e2010-04-03 22:55:48 +0000170- Ensure that tokenization of identifiers is not affected by locale.

177 case it is set.
Victor Stinner00d6a1d2010-03-25 01:02:29 +0000178
Victor Stinner120c2122010-03-25 00:30:28 +0000179- Issue #8226: sys.setfilesystemencoding() raises a LookupError if the encoding
180 is unknown
181

183
Mark Dickinsond59b4162010-03-13 11:34:40 +0000184- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
185 PyMemberDefs could produce an internal error; raise TypeError instead.
186
Mark Dickinsonf673f0c2010-03-13 09:48:39 +0000187- Issue #7845: Rich comparison methods on the complex type now return
188 NotImplemented rather than raising a TypeError when comparing with an
189 incompatible type; this allows user-defined classes to implement their own
190 comparisons with complex.
191
Victor Stinner52f6dd72010-03-12 14:45:56 +0000192- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
193 (SIGINT). If an error occurs while importing the site module, the error is
194 printed and Python exits. Initialize the GIL before importing the site
195 module.
196
Benjamin Petersonae5f2f42010-03-07 17:10:51 +0000197- Issue #7173: Generator finalization could invalidate sys.exc_info().

200 a fatal error in low memory condition.
201
Victor Stinner6aa278e2010-03-03 00:18:49 +0000202- Issue #7820: The parser tokenizer restores all bytes in the right if
203 the BOM check fails.
204
Benjamin Peterson23e018a2010-02-27 17:40:01 +0000205- Handle errors from looking up __prepare__ correctly.
206
Larry Hastings1373a072010-02-24 22:49:58 +0000207- Issue #5939: Add additional runtime checking to ensure a valid capsule
208 in Modules/_ctypes/callproc.c.
209
Eric Smith0facd772010-02-24 15:42:29 +0000210- Issue #7309: Fix unchecked attribute access when converting

223 deprecations.
224
Antoine Pitrou05b7c562010-02-02 22:47:00 +0000225- Issue #7385: Fix a crash in `MemoryView_FromObject` when
226 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
227
Mark Dickinsonbc099642010-01-29 17:27:24 +0000228- Issue #7788: Fix an interpreter crash produced by deleting a list
229 slice with very large step value.
230
Eric Smithf7bb5782010-01-27 00:44:57 +0000231- Issue #7766: Change sys.getwindowsversion() return value to a named
232 tuple and add the additional members returned in an OSVERSIONINFOEX
233 structure. The new members are service_pack_major, service_pack_minor,
234 suite_mask, and product_type.
235
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000236- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
237 could crash in many places because of the PyByteArray_AS_STRING() macro
238 returning NULL. The macro now returns a statically allocated empty
239 string instead.
240
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000241- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
242 where the right hand operand is a set of constants, by turning the set into
243 a frozenset and pre-building it as a constant. The comparison operation
244 is made against the constant instead of building a new set each time it is
245 executed (a similar optimization already existed which turned a list of
246 constants into a pre-built tuple). Patch and additional tests by Dave
247 Malcolm.
248
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000249- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
250 methods of bytes, bytearray and unicode objects by using a common
251 implementation based on stringlib's fast search. Patch by Florent Xicluna.
252
Mark Dickinson45b63652010-01-16 18:10:25 +0000253- Issue #7632: Fix various str -> float conversion bugs present in 2.7
254 alpha 2, including: (1) a serious 'wrong output' bug that could
255 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
256 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000257 strings corresponding to subnormal values, (3) a memory leak for
258 some values large enough to cause overflow, and (4) a number of
259 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000260
Benjamin Petersonaea44282010-01-04 01:10:28 +0000261- The __complex__ method is now looked up on the class of instances to make it
262 consistent with other special methods.

271 negative zero) in ** operator. The behaviour now conforms to that
272 described in C99 Annex F.
273
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000274- Issue #1811: improve accuracy and cross-platform consistency for
275 true division of integers: the result of a/b is now correctly
276 rounded for ints a and b (at least on IEEE 754 platforms), and in
277 particular does not depend on the internal representation of an int.
278
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000279- Issue #6834: replace the implementation for the 'python' and 'pythonw'
280 executables on OSX.
281
282 These executables now work properly with the arch(1) command:
283 ``arch -ppc python`` will start a universal binary version of python
284 in PPC mode (unlike previous releases).
285
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000286- Issue #7466: segmentation fault when the garbage collector is called
287 in the middle of populating a tuple. Patch by Florent Xicluna.
288
Amaury Forgeot d'Arc64f3ca42009-12-01 21:59:18 +0000289- Issue #7419: setlocale() could crash the interpreter on Windows when called
290 with invalid values.
291
Amaury Forgeot d'Arc7d0bddd2009-11-30 00:08:56 +0000292- Issue #6077: On Windows, files opened with tempfile.TemporaryFile in "wt+"
293 mode would appear truncated on the first '0x1a' byte (aka. Ctrl+Z).
294
Ronald Oussoren3c1928a2009-11-19 17:15:31 +0000295- Issue #7085: Fix crash when importing some extensions in a thread

302
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000303- Issue #7298: fixes for range and reversed(range(...)). Iteration
304 over range(a, b, c) incorrectly gave an empty iterator when a, b and
305 c fit in C long but the length of the range did not. Also fix
306 several cases where reversed(range(a, b, c)) gave wrong results, and
307 fix a refleak for reversed(range(a, b, c)) with large arguments.
308
Raymond Hettingerfc438512009-11-01 20:55:33 +0000309- Issue #7244: itertools.izip_longest() no longer ignores exceptions
310 raised during the formation of an output tuple.

418
Antoine Pitrouf978fac2010-05-21 17:25:34 +0000419- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows
420 embedders of the interpreter to set sys.argv without also modifying
421 sys.path. This helps fix `CVE-2008-5983

423
Benjamin Petersonfb886362010-04-24 18:21:17 +0000424- Add PyArg_ValidateKeywordArguments, which checks if all keyword arguments are
425 strings in an efficient manner.
426
Antoine Pitrou8689a102010-04-01 16:53:15 +0000427- Issue #8276: PyEval_CallObject() is now only available in macro form. The
428 function declaration, which was kept for backwards compatibility reasons,
429 is now removed (the macro was introduced in 1997!).

436
Mark Dickinsonde604012010-01-01 19:27:32 +0000437- Issue #5080: The argument parsing functions PyArg_ParseTuple,
438 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
439 PyArg_VaParseTupleAndKeywords and PyArg_Parse now raise a
440 DeprecationWarning for float arguments passed with the 'L' format
441 code. This will become a TypeError in a future version of Python,
442 to match the behaviour of the other integer format codes.
443
Georg Brandl1e28a272009-12-28 08:41:01 +0000444- Issue #7033: function ``PyErr_NewExceptionWithDoc()`` added.

453 in PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be
454 should used for accessing the d_type and d_name members of structures
455 using PyDescr_COMMON.

Gregory P. Smith5a631832010-07-27 05:31:29 +0000521- The default size of the re module's compiled regular expression cache has
522 been increased from 100 to 500 and the cache replacement policy has changed
523 from simply clearing the entire cache on overflow to randomly forgetting 20%
524 of the existing cached compiled regular expressions. This is a performance
525 win for applications that use a lot of regular expressions and limits the
526 impact of the performance hit anytime the cache is exceeded.

539 module. The C module is renamed to `_datetime` and if available,
540 overrides all classes defined in datetime with fast C impementation.
541 Python implementation is based on the original python prototype for

904
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000905- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
906 module now takes an optional timeout argument in seconds. Timeout support
907 relies on the system threading library, so as to avoid a semi-busy wait
908 loop.
909
Victor Stinner485fb562010-04-13 11:07:24 +0000910- Issue #8383: pickle and pickletools use surrogatepass error handler when
911 encoding unicode as utf8 to support lone surrogates and stay compatible with
912 Python 2.x and 3.0
913
R. David Murrayb2416e52010-04-12 16:58:02 +0000914- Issue #7585: difflib context and unified diffs now place a tab between
915 filename and date, conforming to the 'standards' they were originally
916 designed to follow. This improves compatibility with patch tools.
917
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000918- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
919 character sets will now consistently use a Content-Transfer-Encoding of
920 7bit rather than sometimes being marked as 8bit.
921
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000922- Issue #8375: test_distutils now checks if the temporary directory are still
923 present before it cleans them.
924
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000925- Issue #8374: Update the internal alias table in the :mod:`locale` module
926 to cover recent locale changes and additions.
927
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000928- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
929 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
930 and `ssl.OPENSSL_VERSION_NUMBER`.
931
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000932- Add functools.total_ordering() and functools.cmp_to_key().
933
Mark Dickinson089b00c2010-04-03 15:51:03 +0000934- Issue #8257: The Decimal construct now accepts a float instance
935 directly, converting that float to a Decimal of equal value:
936
937 >>> Decimal(1.1)
938 Decimal('1.100000000000000088817841970012523233890533447265625')
939
Mark Dickinson98127c32010-04-03 11:18:52 +0000940- Issue #8294: The Fraction constructor now accepts Decimal and float
941 instances directly.
942
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000943- Issue #7279: Comparisons involving a Decimal signaling NaN now
944 signal InvalidOperation instead of returning False. (Comparisons
945 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
946 are now hashable; Decimal signaling NaNs remain unhashable.
947
948- Issue #2531: Comparison operations between floats and Decimal
949 instances now return a result based on the numeric values of the
950 operands; previously they returned an arbitrary result based on
Mark Dickinson08ade6f2010-06-11 10:44:52 +0000951 the relative ordering of id(float) and id(Decimal). See also
Mark Dickinson9b88b912010-06-11 10:46:57 +0000952 issue #8188, which adds Decimal-to-Fraction comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000953
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000954- Added a subtract() method to collections.Counter().
955
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000956- Issue #8233: When run as a script, py_compile.py optionally takes a single
957 argument `-` which tells it to read files to compile from stdin. Each line
958 is read on demand and the named file is compiled immediately. (Original
959 patch by Piotr Ożarowski).
960
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000961- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
962 form feed (0x0C) are now considered linebreaks, as specified in Unicode
963 Standard Annex #14. See issue #7643.
964 http://www.unicode.org/reports/tr14/
965
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000966- Comparisons using one of <, <=, >, >= between a complex instance and
967 a Fractions instance now raise TypeError instead of returning
968 True/False. This makes Fraction <=> complex comparisons consistent with
969 int <=> complex, float <=> complex, and complex <=> complex comparisons.
970
Antoine Pitrou39b35432010-03-23 00:25:54 +0000971- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
972 some methods (such as oss_mixer_device.fileno()) were not available.
973 Initial patch by Bertrand Janin.
974
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000975- Issue #8205: Remove the "Modules" directory from sys.path when Python is
976 running from the build directory (POSIX only).
977
Antoine Pitrou910bd512010-03-22 20:11:09 +0000978- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
979 didn't support chflags() (for example ZFS under FreeBSD). The error is
980 now silenced.
981
R. David Murrayca2edce2010-03-22 17:48:48 +0000982- Issue #7860: platform.uname now reports the correct 'machine' type
983 when Python is running in WOW64 mode on 64 bit Windows.
984
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000985- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
986 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
987 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000988
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000989- Issue #4282: Fix the main function of the profile module for a non-ASCII
990 script, open the file in binary mode and not in text mode with the default
991 (utf8) encoding.
992
Florent Xicluna54467e02010-03-21 12:29:50 +0000993- Issue #8179: Fix macpath.realpath() on a non-existing path.
994
Florent Xiclunafaa663f2010-03-19 13:37:08 +0000995- Issue #8024: Update the Unicode database to 5.2.
996
Benjamin Peterson00888932010-03-18 22:37:38 +0000997- Issue #8168: py_compile now handles files with utf-8 BOMS.
998
Benjamin Peterson689a5582010-03-18 22:29:52 +0000999- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
1000 detected.
1001
Martin v. Löwis4b003072010-03-16 13:19:21 +00001002- Issue #6716/2: Backslash-replace error output in compilall.
1003
Matthias Klosea6d9abf2010-03-16 10:51:28 +00001004- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
1005 with Tcl/Tk-8.5.
1006

1010 the locale.
1011
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00001012- The internals of the subprocess module on POSIX systems have been replaced
1013 by an extension module (_posixsubprocess) so that the fork()+exec() can be
1014 done safely without the possibility of deadlock in multithreaded applications.
1015
Gregory P. Smith580d60c2010-03-14 07:13:25 +00001016- subprocess.Popen now has restore_signals and start_new_session features.
1017 The default of restore_signals=True is a new behavior compared to earlier
1018 Python versions. This means that signals such as SIGPIPE are not ignored
1019 by default in subprocesses launched by Python (Issue #1652).
1020
Florent Xiclunaf15351d2010-03-13 23:24:31 +00001021- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
1022 cElementTree module is updated too.

1031 the replacement were all bytes. Patch by Antoine Pitrou.
1032
Gerhard Häringf9cee222010-03-05 15:20:03 +00001033- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
1034 bugs and allows loading SQLite extensions from shared libraries.
1035
Ezio Melottida227042010-03-14 11:51:00 +00001036- Issue #1054943: Fix ``unicodedata.normalize('NFC', text)`` for the Public
1037 Review Issue #29 (http://unicode.org/review/pr-29.html).
Victor Stinner7ed9c4c2010-03-04 12:14:57 +00001038
Victor Stinnercee3ae82010-03-04 00:29:24 +00001039- Issue #7494: fix a crash in _lsprof (cProfile) after clearing the profiler,
1040 reset also the pointer to the current pointer context.
1041
Lars Gustäbel01385812010-03-03 12:08:54 +00001042- Issue #7232: Add support for the context manager protocol to the TarFile

1049
Florent Xiclunac279ebf2010-02-27 11:31:21 +00001050- Issue #691291: codecs.open() should not convert end of lines on reading and
1051 writing.
1052
Vinay Sajipdb81c4c2010-02-25 23:13:06 +00001053- Issue #7869: logging: improved diagnostic for format-time errors.

1065
Andrew M. Kuchlinge1f9beb2010-02-22 22:16:58 +00001066- Issue #6666: fix bug in trace.py that applied the list of directories
1067 to be ignored only to the first file. Noted by Bogdan Opanchuk.
1068
Andrew M. Kuchlingfbacb062010-02-22 16:52:52 +00001069- Issue #7597: curses.use_env() can now be called before initscr().

1078 bytecode file when it was less then 8 bytes.
1079
Mark Dickinson84230a12010-02-18 14:49:50 +00001080- Issue #7633: In the decimal module, Context class methods (with the
1081 exception of canonical and is_canonical) now accept instances of int
1082 and long wherever a Decimal instance is accepted, and implicitly
1083 convert that argument to Decimal. Previously only some arguments
1084 were converted.
1085
R. David Murray1f449142010-02-11 00:15:05 +00001086- Issue #7835: shelve should no longer produce mysterious warnings during
1087 interpreter shutdown.
1088
Antoine Pitrou99f69ee2010-02-09 17:25:47 +00001089- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
1090 in XML processing instructions and comments. These raw characters are
1091 allowed by the XML specification, and are necessary when outputting e.g.
1092 PHP code in a processing instruction. Patch by Neil Muller.
1093
Antoine Pitrouc77dd322010-02-09 16:51:16 +00001094- Issue #6233: ElementTree failed converting unicode characters to XML

1099 specify the compression type.
1100
Antoine Pitroub6375f12010-02-04 20:23:24 +00001101- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
1102 specified, rather than fall through to AF_PACKET (in the `socket` module).
1103 Also, raise ValueError rather than TypeError when an unknown TIPC address
1104 type is specified. Patch by Brian Curtin.
1105
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00001106- Issue #6939: Fix file I/O objects in the `io` module to keep the original
1107 file position when calling `truncate()`. It would previously change the
1108 file position to the given argument, which goes against the tradition of
1109 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1110
Antoine Pitroua32f9a22010-01-27 21:18:57 +00001111- Issue #7610: Reworked implementation of the internal
1112 :class:`zipfile.ZipExtFile` class used to represent files stored inside
1113 an archive. The new implementation is significantly faster and can
1114 be wrapped in a :class:`io.BufferedReader` object for more speedups.
1115 It also solves an issue where interleaved calls to `read()` and
1116 `readline()` give wrong results. Patch by Nir Aides.
1117
Jesse Noller1f0b6582010-01-27 03:36:01 +00001118- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,
1119 allowing for a maximum number of tasks within the pool to be completed by
1120 the worker before that worker is terminated, and a new one created to
1121 replace it.
1122
Benjamin Petersond6326642010-01-27 02:25:58 +00001123- Issue #7792: Registering non-classes to ABCs raised an obscure error.
1124
Benjamin Peterson9a11a362010-01-27 01:51:29 +00001125- Issue #7785: Don't accept bytes in FileIO.write().

1172 and make it implement the `io.BufferedIOBase` ABC to allow for further
1173 speedups by wrapping it in an `io.BufferedReader`. Patch by Nir Aides.
1174
1175- Issue #3972: http.client.HTTPConnection now accepts an optional source_address
Gregory P. Smithb4066372010-01-03 03:28:29 +00001176 parameter to allow specifying where your connections come from.
1177

Nick Coghlan260bd3e2009-11-16 06:49:25 +00001279- Issue #6816: runpy now provides a run_path function that allows Python code
1280 to execute file paths that refer to source or compiled Python files as well
1281 as zipfiles, directories and other valid sys.path entries that contain a
1282 __main__.py file. This allows applications that run other Python scripts to

Victor Stinnere125f132010-05-15 21:04:43 +00001302 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +00001303 recursive locks as fast as regular non-recursive locks (previously,
1304 they were slower by 10x to 15x).

1324 reading from stdin so that existing input does not confuse it and

1326 afterwards to avoid the terminal echoing the input afterwards on
1327 OSes such as Solaris.

1514
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00001515- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
1516 compared to other unix systems. In particular, os.getgroups() does
1517 not reflect any changes made using os.setgroups() but basicly always
1518 returns the same information as the id command.
1519
1520 os.getgroups() can now return more than 16 groups on MacOSX.

Alexander Belopolsky75f94c22010-06-21 15:21:14 +00001546- Issue #9005: Prevent utctimetuple() from producing year 0 or year
1547 10,000. Prior to this change, timezone adjustment in utctimetuple()
1548 could produce tm_year value of 0 or 10,000. Now an OverflowError is
1549 raised in these edge cases.
1550
Alexander Belopolskyca94f552010-06-17 18:30:34 +00001551- Issue #6641: The ``datetime.strptime`` method now supports the
1552 ``%z`` directive. When the ``%z`` directive is present in the
1553 format string, an aware ``datetime`` object is returned with
1554 ``tzinfo`` bound to a ``datetime.timezone`` instance constructed
1555 from the parsed offset. If both ``%z`` and ``%Z`` are present, the
1556 data in ``%Z`` field is used for timezone name, but ``%Z`` data
1557 without ``%z`` is discarded.
1558
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00001559- Issue #5094: The ``datetime`` module now has a simple concrete class
1560 implementing ``datetime.tzinfo`` interface. Instances of the new
1561 class, ``datetime.timezone``, return fixed name and UTC offset from
1562 their ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)``
1563 method always returns ``None``. A class attribute, ``utc`` contains
1564 an instance representing the UTC timezone. Original patch by Rafe
1565 Kaplan.
1566
Mark Dickinson4b80ef52010-06-12 15:17:02 +00001567- Issue #8973: Add __all__ to struct module; this ensures that

1569
Alexander Belopolskyfcdc79a2010-06-12 17:18:45 +00001570- Issue #3129: Trailing digits in struct format string are no longer ignored.
Victor Stinnerda0eca42010-06-11 21:50:30 +00001571 For example, "1" or "ilib123" are now invalid formats and cause

Stefan Kraha3ac44e2010-06-08 14:00:52 +00001574- Issue #7384: If the system readline library is linked against ncurses,
1575 the curses module must be linked against ncurses as well. Otherwise it
1576 is not safe to load both the readline and curses modules in an application.

1580
Mark Dickinson4c8a9a22010-05-15 17:02:38 +00001581- Issue #8692: Optimize math.factorial: replace the previous naive
1582 algorithm with an improved 'binary-split' algorithm that uses fewer
1583 multiplications and allows many of the multiplications to be
1584 performed using plain C integer arithmetic instead of PyLong
1585 arithmetic. Also uses a lookup table for small arguments.
1586
Mark Dickinson85eacea2010-05-10 16:27:45 +00001587- Issue #8674: Fixed a number of incorrect or undefined-behaviour-inducing

1589
Mark Dickinson0381e3f2010-05-08 14:35:02 +00001590- Issue #8644: The accuracy of td.total_seconds() has been improved (by
1591 calculating with integer arithmetic instead of float arithmetic internally):
1592 the result is now always correctly rounded, and is equivalent to td /
1593 timedelta(seconds=1).
1594
Mark Dickinson7c186e22010-04-20 22:32:49 +00001595- Issue #2706: Allow division of a timedelta by another timedelta:
1596 timedelta / timedelta, timedelta % timedelta, timedelta // timedelta
1597 and divmod(timedelta, timedelta) are all supported.

1600
Mark Dickinsonc5935772010-04-03 15:54:36 +00001601- Issue #8300: When passing a non-integer argument to struct.pack with any
1602 integer format code, struct.pack first attempts to convert the non-integer
1603 using its __index__ method. If that method is non-existent or raises
1604 TypeError it goes on to try the __int__ method, as described below.
1605
Matthias Klosea8349752010-03-15 13:25:28 +00001606- Issue #8142: Update libffi to the 3.0.9 release.

Antoine Pitrou65c9c642009-10-30 17:25:12 +00001870- Issue #7222: Make thread "reaping" more reliable so that reference
1871 leak-chasing test runs give sensible results. The previous method of
1872 reaping threads could return successfully while some Thread objects were
1873 still referenced. This also introduces a new private function:
1874 :func:`_thread._count()`.
1875
R. David Murray27144602009-10-19 15:26:16 +00001876- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1877 longer runs the risk of causing the worker thread to fail.
1878
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001879- Issue #7055: test___all__ now greedily detects all modules which have an
1880 __all__ attribute, rather than using a hardcoded and incomplete list.

1883 runtest_inner in regrtest, with warnings if the called test modifies them,
1884 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001885
Mark Dickinson2e304402009-10-04 18:43:54 +00001886- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1887
Brett Cannon3c273842009-07-20 00:14:29 +00001888- Fixed tests in importlib.test.source.test_abc_loader that were masking
1889 the proper exceptions that should be raised for missing or improper code
1890 object bytecode.
1891
Brett Cannonb49c70c2009-07-15 04:08:33 +00001892- Removed importlib's custom test discovery code and switched to

2056 (1) inf and nan strings with trailing whitespace were incorrectly
2057 rejected; (2) parsing of strings representing infinities and nans
2058 was locale aware; and (3) the interpretation of fromhex('-nan')
2059 didn't match that of float('-nan').

2162Core and Builtins
2163-----------------
2164
Mark Dickinson865e01a2009-05-07 16:37:01 +00002165- Issue #5914: Add new C API function PyOS_string_to_double, and
2166 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
2167
Eric Smith741191f2009-05-06 13:08:15 +00002168- Issue #3382: float.__format__, complex.__format__, and %-formatting
2169 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
2170 affects nan -> NAN and inf -> INF.
2171
Mark Hammond5a607a32009-05-06 08:04:54 +00002172- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
2173 in all operations, including splitdrive, split, etc. splitunc() now issues
2174 a PendingDeprecation warning.
2175
Eric Smith63376222009-05-05 14:04:18 +00002176- Issue #5920: For float.__format__, change the behavior with the
2177 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
2178 to be like 'g' but with at least one decimal point and with a
2179 default precision of 12. Previously, the behavior the same but with
2180 a default precision of 6. This more closely matches str(), and
2181 reduces surprises when adding alignment flags to the empty
2182 presentation type. This also affects the new complex.__format__ in
2183 the same way.
2184
Martin v. Löwis011e8422009-05-05 04:43:17 +00002185- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
2186
R. David Murrayb18500d2009-05-04 22:59:07 +00002187- Issue #5890: in subclasses of 'property' the __doc__ attribute was
2188 shadowed by classtype's, even if it was None. property now
2189 inserts the __doc__ into the subclass instance __dict__.
2190
Antoine Pitrou244651a2009-05-04 18:56:13 +00002191- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
2192 sequences. Patch by Nick Barnes and Victor Stinner.
2193
Martin v. Löwise0a2b722009-05-10 08:08:56 +00002194- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00002195
Benjamin Petersond2e0c792009-05-01 20:40:59 +00002196- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
2197 received a new method, detach(). detach() disconnects the underlying stream
2198 from the buffer or text IO and returns it.
2199
Mark Dickinson33841c32009-05-01 15:37:04 +00002200- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
2201 floats with absolute value over 1e50. Also remove length
2202 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
2203 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00002204
Eric Smith741191f2009-05-06 13:08:15 +00002205- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00002206 format(complex(1, 2./3), '.5') now produces a sensible result.
2207
Mark Dickinsond3ca5572009-04-29 18:47:07 +00002208- Issue #5864: Fix empty format code formatting for floats so that it
2209 never gives more than the requested number of significant digits.
2210
Eric Smith6dc46f52009-04-27 20:39:49 +00002211- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
2212 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
2213
Eric Smithcc32a112009-04-26 21:35:14 +00002214- Issue #5835: Deprecate PyOS_ascii_formatd.
2215
Martin v. Löwis71efeb72009-04-26 01:02:07 +00002216- Issue #4971: Fix titlecase for characters that are their own
2217 titlecase, but not their own uppercase.
2218
Benjamin Peterson193152c2009-04-25 01:08:45 +00002219- Issue #5283: Setting __class__ in __del__ caused a segfault.
2220
Mark Dickinsonad476da2009-04-23 19:14:16 +00002221- Issue #5816: complex(repr(z)) now recovers z exactly, even when
2222 z involves nans, infs or negative zeros.
2223
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00002224- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00002225
Mark Dickinsone6a076d2009-04-18 11:48:33 +00002226- Issue #1869 (and many duplicates): make round(x, n) correctly
2227 rounded for a float x, by using the decimal <-> binary conversions
2228 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2229 consistently agrees with format(x, '.2f').
2230
Benjamin Petersonae937c02009-04-18 20:54:08 +00002231- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
2232 some builtin types.
2233
Eric Smith0923d1d2009-04-16 20:16:10 +00002234- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
2235
Eric Smith35e84722009-04-16 20:21:28 +00002236- Issue #5515: str.format() type 'n' combined with commas and leading
2237 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002238
2239- Implement PEP 378, Format Specifier for Thousands Separator, for
2240 floats.
2241
Mark Dickinson3370cce2009-04-17 22:40:53 +00002242- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002243 1e11, not 1e12. This avoids printing 13 significant digits in
2244 situations where only 12 of them are correct. Example problem
2245 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2246 long time.)
2247
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002248- Issue #1580: On most platforms, use a 'short' float repr: for a
2249 finite float x, repr(x) now outputs a string based on the shortest
2250 sequence of decimal digits that rounds to x. Previous behaviour was
2251 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002252 Another minor difference is that the new repr switches to
2253 exponential notation at 1e16 instead of the previous 1e17; this
2254 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002255
2256 There's a new sys attribute sys.float_repr_style, which takes
2257 the value 'short' to indicate that we're using short float repr,
2258 and 'legacy' if the short float repr isn't available for one
2259 reason or another.
2260
2261 The float repr change involves incorporating David Gay's 'perfect
2262 rounding' code into the Python core (it's in Python/dtoa.c). As a
2263 secondary consequence, all string-to-float and float-to-string
2264 conversions (including all float formatting operations) will be
2265 correctly rounded on these platforms.
2266
2267 See issue 1580 discussions for details of platforms for which
2268 this change does not apply.
2269
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002270- Issue #5759: float() didn't call __float__ on str subclasses.
2271
Georg Brandlabc38772009-04-12 15:51:51 +00002272- The string.maketrans() function is deprecated; there is a new static method
2273 maketrans() on the bytes and bytearray classes. This removes confusion about
2274 the types string.maketrans() is supposed to work with, and mirrors the
2275 methods available on the str class.
2276
R. David Murraydc6da8a2009-04-09 22:16:43 +00002277- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
2278 its clarity and its speed.
2279
Matthias Klose091c7b12009-04-07 13:24:27 +00002280- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
2281 to avoid compiler warnings.
2282
Walter Dörwald8dc33d52009-05-06 14:41:26 +00002283- Issue #3739: The unicode-internal encoder now reports the number of characters
2284 consumed like any other encoder (instead of the number of bytes).

2627 destroying them does not show quadratic performance. Based on a proposal by
2628 Martin von Löwis at
2629 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

Vinay Sajip6268cbc2009-01-21 00:19:28 +00002631- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002632 having been closed (for instance, a read() call could return some
2633 previously buffered data). Patch by Dmitry Vasiliev.
2634
Antoine Pitrou05608432009-01-09 18:53:14 +00002635- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2636 flag to work properly. Furthermore, when specifying -u, the text stdout
2637 and stderr streams have line-by-line buffering enabled (the default being
2638 to buffer arbitrary chunks of data).
2639
Raymond Hettinger35631532009-01-09 03:58:09 +00002640- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2641 instead of ints (reducing its size from 4 to 8 times thereby reducing
2642 Python's overall memory).
2643
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002644- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2645 an existing .py counterpart, override the co_filename attributes of all
2646 code objects if the original filename is obsolete (which can happen if the
2647 file has been renamed, moved, or if it is accessed through different paths).
2648 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2649
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002650- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2651 one byte. Also fixes the meaning of len() so that it returns the number of
2652 items, rather than the size in bytes.
2653
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002654- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002656- Issue #4747: When the terminal does not use utf-8, executing a script with
2657 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2658

2663 did not get collected.
2664
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002665- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2666 where the tp_hash and tp_dict slots are both NULL.
2667
Georg Brandlccc47b62008-12-28 11:44:14 +00002668- Issue #4759: None is now allowed as the first argument of
2669 bytearray.translate(). It was always allowed for bytes.translate().
2670
Skip Montanaro80072cb2008-12-23 03:51:14 +00002671- Added test case to ensure attempts to read from a file opened for writing
2672 fail.
2673
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002674- Issue #3106: Speedup some comparisons (str/str and int/int).

2678
Antoine Pitrou621601a2008-12-17 23:18:19 +00002679- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

2686 nl_langinfo is not the empty string. This was causing silent build
2687 failures on OS X.
2688
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002689- Issue #4597: Fixed several opcodes that weren't always propagating
2690 exceptions.
2691
2692- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002693 context manager returns a value that cannot be converted to a bool.
2694
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002695- Issue #4445: Replace "sizeof(PyBytesObject)" with
2696 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2697 bytes instances. On a typical machine this saves 3 bytes of memory
2698 (on average) per allocation of a bytes instance.
2699
Christian Heimesa872de52008-12-05 08:26:55 +00002700- Issue #4533: File read operation was dreadfully slow due to a slowly
2701 growing read buffer. Fixed by using the same growth rate algorithm as
2702 Python 2.x.
2703
Antoine Pitrou5504e892008-12-06 21:27:53 +00002704- Issue #4509: Various issues surrounding resize of bytearray objects to
2705 which there are buffer exports (e.g. memoryview instances).
2706
Georg Brandlf9734072008-12-07 15:30:06 +00002707- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2708 method on file objects with closefd=False. The file descriptor is still
2709 kept open but the file object behaves like a closed file. The ``FileIO``
2710 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00002712- Issue #4569: Interpreter crash when mutating a memoryview with an item size

2718
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002719- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2720 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2721 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2722 of using the replace error handler in PyUnicode_DecodeUTF8().

3043 do an explicit seek to the end of file (so that e.g. tell() returns the
