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

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

416
Antoine Pitrouf978fac2010-05-21 17:25:34 +0000417- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows
418 embedders of the interpreter to set sys.argv without also modifying

436 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
437 PyArg_VaParseTupleAndKeywords and PyArg_Parse now raise a
438 DeprecationWarning for float arguments passed with the 'L' format
439 code. This will become a TypeError in a future version of Python,
440 to match the behaviour of the other integer format codes.
441
Georg Brandl1e28a272009-12-28 08:41:01 +0000442- Issue #7033: function ``PyErr_NewExceptionWithDoc()`` added.

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

477
Gregory P. Smith5a631832010-07-27 05:31:29 +0000478- The default size of the re module's compiled regular expression cache has
479 been increased from 100 to 500 and the cache replacement policy has changed
480 from simply clearing the entire cache on overflow to randomly forgetting 20%
481 of the existing cached compiled regular expressions. This is a performance
482 win for applications that use a lot of regular expressions and limits the
483 impact of the performance hit anytime the cache is exceeded.

Alexander Belopolskycf86e362010-07-23 19:25:47 +0000495- Issue #7989: Added pure python implementation of the `datetime`
496 module. The C module is renamed to `_datetime` and if available,
497 overrides all classes defined in datetime with fast C impementation.
498 Python implementation is based on the original python prototype for
499 the datetime module by Tim Peters with minor modifications by the
500 PyPy project. The test suite now tests `datetime` module with and
501 without `_datetime` acceleration using the same test cases.

741
Mark Dickinsonc69160e2010-05-04 14:35:33 +0000742- Issue #8567: Fix precedence of signals in Decimal module: when a
743 Decimal operation raises multiple signals and more than one of those
744 signals is trapped, the specification determines the order in which
745 the signals should be handled. In many cases this order wasn't
746 being followed, leading to the wrong Python exception being raised.

779
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000780- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
781 where the method could block indefinitely if called just before the
782 event loop started running. This also fixes the occasional freezes
783 witnessed in test_httpservers.
784
Antoine Pitrou40f08742010-04-24 22:04:40 +0000785- Issue #8524: When creating an SSL socket, the timeout value of the
786 original socket wasn't retained (instead, a socket with a positive timeout
787 would be turned into a non-blocking SSL socket).
788
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000789- Issue #5103: SSL handshake would ignore the socket timeout and block
790 indefinitely if the other end didn't respond.
791
792- The do_handshake() method of SSL objects now adjusts the blocking mode of
793 the SSL structure if necessary (as other methods already do).
794
Victor Stinner13bb71c2010-04-23 21:41:56 +0000795- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates

Mark Dickinsonac256ab2010-04-03 11:08:14 +0000900- Issue #7279: Comparisons involving a Decimal signaling NaN now
901 signal InvalidOperation instead of returning False. (Comparisons
902 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
903 are now hashable; Decimal signaling NaNs remain unhashable.
904
905- Issue #2531: Comparison operations between floats and Decimal
906 instances now return a result based on the numeric values of the
907 operands; previously they returned an arbitrary result based on
Mark Dickinson08ade6f2010-06-11 10:44:52 +0000908 the relative ordering of id(float) and id(Decimal). See also
Mark Dickinson9b88b912010-06-11 10:46:57 +0000909 issue #8188, which adds Decimal-to-Fraction comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000910
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000911- Added a subtract() method to collections.Counter().
912
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000913- Issue #8233: When run as a script, py_compile.py optionally takes a single
914 argument `-` which tells it to read files to compile from stdin. Each line
915 is read on demand and the named file is compiled immediately. (Original
916 patch by Piotr Ożarowski).
917
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000918- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
919 form feed (0x0C) are now considered linebreaks, as specified in Unicode
920 Standard Annex #14. See issue #7643.
921 http://www.unicode.org/reports/tr14/
922
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000923- Comparisons using one of <, <=, >, >= between a complex instance and
924 a Fractions instance now raise TypeError instead of returning
925 True/False. This makes Fraction <=> complex comparisons consistent with
926 int <=> complex, float <=> complex, and complex <=> complex comparisons.
927
Antoine Pitrou39b35432010-03-23 00:25:54 +0000928- Issue #8139: ossaudiodev didn't initialize its types properly, therefore

940 when Python is running in WOW64 mode on 64 bit Windows.
941
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000942- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
943 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking

968
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000969- The internals of the subprocess module on POSIX systems have been replaced
970 by an extension module (_posixsubprocess) so that the fork()+exec() can be
971 done safely without the possibility of deadlock in multithreaded applications.
972
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000973- subprocess.Popen now has restore_signals and start_new_session features.
974 The default of restore_signals=True is a new behavior compared to earlier
975 Python versions. This means that signals such as SIGPIPE are not ignored
976 by default in subprocesses launched by Python (Issue #1652).
977
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000978- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The

1038 exception of canonical and is_canonical) now accept instances of int
1039 and long wherever a Decimal instance is accepted, and implicitly
1040 convert that argument to Decimal. Previously only some arguments
1041 were converted.

1062
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00001063- Issue #6939: Fix file I/O objects in the `io` module to keep the original
1064 file position when calling `truncate()`. It would previously change the
1065 file position to the given argument, which goes against the tradition of
1066 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1067
Antoine Pitroua32f9a22010-01-27 21:18:57 +00001068- Issue #7610: Reworked implementation of the internal
1069 :class:`zipfile.ZipExtFile` class used to represent files stored inside
1070 an archive. The new implementation is significantly faster and can
1071 be wrapped in a :class:`io.BufferedReader` object for more speedups.
1072 It also solves an issue where interleaved calls to `read()` and
1073 `readline()` give wrong results. Patch by Nir Aides.

Nick Coghlan260bd3e2009-11-16 06:49:25 +00001236- Issue #6816: runpy now provides a run_path function that allows Python code
1237 to execute file paths that refer to source or compiled Python files as well
1238 as zipfiles, directories and other valid sys.path entries that contain a
1239 __main__.py file. This allows applications that run other Python scripts to
1240 support the same flexibility as the CPython command line itself.

Victor Stinnere125f132010-05-15 21:04:43 +00001259 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +00001260 recursive locks as fast as regular non-recursive locks (previously,
1261 they were slower by 10x to 15x).
1262

1278 failures on systems with slightly bogus mtime behaviour.
1279
Gregory P. Smith50467882009-11-01 18:42:17 +00001280- Issue #7246 & Issue #7208: getpass now properly flushes input before
1281 reading from stdin so that existing input does not confuse it and
1282 lead to incorrect entry or an IOError. It also properly flushes it
1283 afterwards to avoid the terminal echoing the input afterwards on
1284 OSes such as Solaris.
1285
Mark Dickinsona2d1fe02009-10-29 12:23:02 +00001286- Issue #7233: Fix a number of two-argument Decimal methods to make

1480 (e.g., struct.pack('>?')): if conversion to bool raised an exception
Mark Dickinson1b3c2622010-07-18 08:03:10 +00001481 then that exception wasn't properly propagated on machines where
1482 char is unsigned.

Alexander Belopolsky75f94c22010-06-21 15:21:14 +00001501- Issue #9005: Prevent utctimetuple() from producing year 0 or year
1502 10,000. Prior to this change, timezone adjustment in utctimetuple()
1503 could produce tm_year value of 0 or 10,000. Now an OverflowError is
1504 raised in these edge cases.
1505
Alexander Belopolskyca94f552010-06-17 18:30:34 +00001506- Issue #6641: The ``datetime.strptime`` method now supports the
1507 ``%z`` directive. When the ``%z`` directive is present in the
1508 format string, an aware ``datetime`` object is returned with
1509 ``tzinfo`` bound to a ``datetime.timezone`` instance constructed
1510 from the parsed offset. If both ``%z`` and ``%Z`` are present, the
1511 data in ``%Z`` field is used for timezone name, but ``%Z`` data
1512 without ``%z`` is discarded.
1513
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00001514- Issue #5094: The ``datetime`` module now has a simple concrete class
1515 implementing ``datetime.tzinfo`` interface. Instances of the new
1516 class, ``datetime.timezone``, return fixed name and UTC offset from
1517 their ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)``
1518 method always returns ``None``. A class attribute, ``utc`` contains
1519 an instance representing the UTC timezone. Original patch by Rafe
1520 Kaplan.

1537 algorithm with an improved 'binary-split' algorithm that uses fewer
1538 multiplications and allows many of the multiplications to be
1539 performed using plain C integer arithmetic instead of PyLong
1540 arithmetic. Also uses a lookup table for small arguments.

1544
Mark Dickinson0381e3f2010-05-08 14:35:02 +00001545- Issue #8644: The accuracy of td.total_seconds() has been improved (by

1547 the result is now always correctly rounded, and is equivalent to td /
1548 timedelta(seconds=1).

Mark Dickinsonc5935772010-04-03 15:54:36 +00001556- Issue #8300: When passing a non-integer argument to struct.pack with any
1557 integer format code, struct.pack first attempts to convert the non-integer

1799 user running the tests.

1805 a test fails. Can be combined with -j.
1806
Antoine Pitrou060cee22009-11-13 16:29:04 +00001807- Issue #6551: test_zipimport could import and then destroy some modules of

1823 calling methods on the object.
1824
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001825- Issue #7222: Make thread "reaping" more reliable so that reference
1826 leak-chasing test runs give sensible results. The previous method of
1827 reaping threads could return successfully while some Thread objects were
1828 still referenced. This also introduces a new private function:
1829 :func:`_thread._count()`.
1830
R. David Murray27144602009-10-19 15:26:16 +00001831- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1832 longer runs the risk of causing the worker thread to fail.
1833
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001834- Issue #7055: test___all__ now greedily detects all modules which have an
1835 __all__ attribute, rather than using a hardcoded and incomplete list.

1838 runtest_inner in regrtest, with warnings if the called test modifies them,
1839 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001840
Mark Dickinson2e304402009-10-04 18:43:54 +00001841- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1842
Brett Cannon3c273842009-07-20 00:14:29 +00001843- Fixed tests in importlib.test.source.test_abc_loader that were masking
1844 the proper exceptions that should be raised for missing or improper code
1845 object bytecode.
1846
Brett Cannonb49c70c2009-07-15 04:08:33 +00001847- Removed importlib's custom test discovery code and switched to

2039 than an int, which makes some operations possible under 64-bit Linux (e.g.
2040 DN_MULTISHOT with F_NOTIFY).
2041
Antoine Pitrou716c4442009-05-23 19:04:03 +00002042- Issue #5761: Add the name of the underlying file to the repr() of various

2047
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00002048- Issue #1983: Fix functions taking or returning a process identifier to use
2049 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
2050 a process identifier type wider than the standard C integer type.
2051
R. David Murray87e20742009-05-23 01:30:26 +00002052- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

2063
Antoine Pitroue4501852009-05-14 18:55:55 +00002064- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
2065 library. This means, for example, that opening an UTF-16 text file in
2066 append mode doesn't add a BOM at the end of the file if the file isn't
2067 empty.
2068
R. David Murray74b89242009-05-13 17:33:03 +00002069- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
2070 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
2071 corrects a pydoc regression.
2072
R. David Murray99352742009-05-07 18:24:38 +00002073- Issue 5955: aifc's close method did not close the file it wrapped,
2074 now it does. This also means getfp method now returns the real fp.

2117Core and Builtins
2118-----------------
2119
Mark Dickinson865e01a2009-05-07 16:37:01 +00002120- Issue #5914: Add new C API function PyOS_string_to_double, and
2121 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
2122
Eric Smith741191f2009-05-06 13:08:15 +00002123- Issue #3382: float.__format__, complex.__format__, and %-formatting
2124 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
2125 affects nan -> NAN and inf -> INF.
2126
Mark Hammond5a607a32009-05-06 08:04:54 +00002127- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
2128 in all operations, including splitdrive, split, etc. splitunc() now issues
2129 a PendingDeprecation warning.
2130
Eric Smith63376222009-05-05 14:04:18 +00002131- Issue #5920: For float.__format__, change the behavior with the
2132 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
2133 to be like 'g' but with at least one decimal point and with a
2134 default precision of 12. Previously, the behavior the same but with
2135 a default precision of 6. This more closely matches str(), and
2136 reduces surprises when adding alignment flags to the empty
2137 presentation type. This also affects the new complex.__format__ in
2138 the same way.
2139
Martin v. Löwis011e8422009-05-05 04:43:17 +00002140- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
2141
R. David Murrayb18500d2009-05-04 22:59:07 +00002142- Issue #5890: in subclasses of 'property' the __doc__ attribute was
2143 shadowed by classtype's, even if it was None. property now
2144 inserts the __doc__ into the subclass instance __dict__.
2145
Antoine Pitrou244651a2009-05-04 18:56:13 +00002146- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
2147 sequences. Patch by Nick Barnes and Victor Stinner.
2148
Martin v. Löwise0a2b722009-05-10 08:08:56 +00002149- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00002150
Benjamin Petersond2e0c792009-05-01 20:40:59 +00002151- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
2152 received a new method, detach(). detach() disconnects the underlying stream
2153 from the buffer or text IO and returns it.
2154
Mark Dickinson33841c32009-05-01 15:37:04 +00002155- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
2156 floats with absolute value over 1e50. Also remove length
2157 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
2158 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00002159
Eric Smith741191f2009-05-06 13:08:15 +00002160- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00002161 format(complex(1, 2./3), '.5') now produces a sensible result.
2162
Mark Dickinsond3ca5572009-04-29 18:47:07 +00002163- Issue #5864: Fix empty format code formatting for floats so that it
2164 never gives more than the requested number of significant digits.
2165
Eric Smith6dc46f52009-04-27 20:39:49 +00002166- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
2167 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
2168
Eric Smithcc32a112009-04-26 21:35:14 +00002169- Issue #5835: Deprecate PyOS_ascii_formatd.
2170
Martin v. Löwis71efeb72009-04-26 01:02:07 +00002171- Issue #4971: Fix titlecase for characters that are their own
2172 titlecase, but not their own uppercase.
2173
Benjamin Peterson193152c2009-04-25 01:08:45 +00002174- Issue #5283: Setting __class__ in __del__ caused a segfault.
2175
Mark Dickinsonad476da2009-04-23 19:14:16 +00002176- Issue #5816: complex(repr(z)) now recovers z exactly, even when
2177 z involves nans, infs or negative zeros.
2178
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00002179- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00002180
Mark Dickinsone6a076d2009-04-18 11:48:33 +00002181- Issue #1869 (and many duplicates): make round(x, n) correctly
2182 rounded for a float x, by using the decimal <-> binary conversions
2183 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2184 consistently agrees with format(x, '.2f').
2185
Benjamin Petersonae937c02009-04-18 20:54:08 +00002186- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
2187 some builtin types.
2188
Eric Smith0923d1d2009-04-16 20:16:10 +00002189- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
2190
Eric Smith35e84722009-04-16 20:21:28 +00002191- Issue #5515: str.format() type 'n' combined with commas and leading
2192 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002193
2194- Implement PEP 378, Format Specifier for Thousands Separator, for
2195 floats.
2196
Mark Dickinson3370cce2009-04-17 22:40:53 +00002197- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002198 1e11, not 1e12. This avoids printing 13 significant digits in
2199 situations where only 12 of them are correct. Example problem
2200 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2201 long time.)
2202
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002203- Issue #1580: On most platforms, use a 'short' float repr: for a
2204 finite float x, repr(x) now outputs a string based on the shortest
2205 sequence of decimal digits that rounds to x. Previous behaviour was
2206 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002207 Another minor difference is that the new repr switches to
2208 exponential notation at 1e16 instead of the previous 1e17; this
2209 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002210
2211 There's a new sys attribute sys.float_repr_style, which takes
2212 the value 'short' to indicate that we're using short float repr,
2213 and 'legacy' if the short float repr isn't available for one
2214 reason or another.
2215
2216 The float repr change involves incorporating David Gay's 'perfect
2217 rounding' code into the Python core (it's in Python/dtoa.c). As a
2218 secondary consequence, all string-to-float and float-to-string
2219 conversions (including all float formatting operations) will be
2220 correctly rounded on these platforms.
2221
2222 See issue 1580 discussions for details of platforms for which
2223 this change does not apply.
2224
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002225- Issue #5759: float() didn't call __float__ on str subclasses.
2226
Georg Brandlabc38772009-04-12 15:51:51 +00002227- The string.maketrans() function is deprecated; there is a new static method
2228 maketrans() on the bytes and bytearray classes. This removes confusion about
2229 the types string.maketrans() is supposed to work with, and mirrors the
2230 methods available on the str class.
2231
R. David Murraydc6da8a2009-04-09 22:16:43 +00002232- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
2233 its clarity and its speed.
2234
Matthias Klose091c7b12009-04-07 13:24:27 +00002235- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
2236 to avoid compiler warnings.
2237
Walter Dörwald8dc33d52009-05-06 14:41:26 +00002238- Issue #3739: The unicode-internal encoder now reports the number of characters
2239 consumed like any other encoder (instead of the number of bytes).

2377
Benjamin Peterson7fe98532009-04-02 00:33:55 +00002378- Issue #5499: The 'c' code for argument parsing functions now only accepts a
2379 byte, and the 'C' code only accepts a unicode character.
2380
Georg Brandl406b3d82009-04-11 21:24:37 +00002381- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
2382 when hitting the recursion limit under certain circumstances.
2383
Brett Cannon0759dd62009-04-01 18:13:07 +00002384- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
2385
Georg Brandlab6f2f62009-03-31 04:16:10 +00002386- Fix a segfault when running test_exceptions with coverage, caused by
2387 insufficient checks in accessors of Exception.__context__.
2388
Guido van Rossum0ad59d42009-03-30 22:01:35 +00002389- Issue #5604: non-ASCII characters in module name passed to
2390 imp.find_module() were converted to UTF-8 while the path is
2391 converted to the default filesystem encoding, causing nonsense.

2394
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00002395- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
2396 the end sys.path, for compatibility with the system install of Python.
2397
Antoine Pitrou3a652b12009-03-23 18:52:06 +00002398- Issue #4688: Add a heuristic so that tuples and dicts containing only
2399 untrackable objects are not tracked by the garbage collector. This can
2400 reduce the size of collections and therefore the garbage collection overhead
2401 on long-running programs, depending on their particular use of datatypes.
2402
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00002403- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

2415 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
2416 and sizeof(Py_UNICODE) == 2.
2417
Eric Smith8ec90442009-03-14 12:29:34 +00002418- Issue #5237: Allow auto-numbered fields in str.format(). For

2420
Antoine Pitrou652e7072009-03-13 19:25:20 +00002421- Issue #5392: when a very low recursion limit was set, the interpreter would
2422 abort with a fatal error after the recursion limit was hit twice.
2423
Matthias Klose042f1332009-04-04 14:32:42 +00002424- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

2467
Benjamin Peterson59406a92009-03-26 17:10:29 +00002468- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and

2470
Lars Gustäbel42e00912009-03-22 20:34:29 +00002471- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
2472 forever on incomplete input. That caused tarfile.open() to hang when used
2473 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
2474 partial bzip2 compressed data.
2475
Mark Dickinson79f52032009-03-17 23:12:51 +00002476- Issue #2110: Add support for thousands separator and 'n' type

2544 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2545 evaluation loop is compiled with a new dispatch mechanism which gives
2546 speedups of up to 20%, depending on the system, on various benchmarks.

2559 type to (void *).
2560
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002561- Issue #4935: The overflow checking code in the expandtabs() method common
2562 to str, bytes and bytearray could be optimized away by the compiler, letting
2563 the interpreter segfault instead of raising an error.
2564
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002565- Issue #3720: Fix a crash when an iterator modifies its class and removes its

2588 previously buffered data). Patch by Dmitry Vasiliev.
2589
Antoine Pitrou05608432009-01-09 18:53:14 +00002590- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2591 flag to work properly. Furthermore, when specifying -u, the text stdout
2592 and stderr streams have line-by-line buffering enabled (the default being
2593 to buffer arbitrary chunks of data).
2594
Raymond Hettinger35631532009-01-09 03:58:09 +00002595- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2596 instead of ints (reducing its size from 4 to 8 times thereby reducing

2598
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002599- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2600 an existing .py counterpart, override the co_filename attributes of all
2601 code objects if the original filename is obsolete (which can happen if the
2602 file has been renamed, moved, or if it is accessed through different paths).
2603 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2604
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002605- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2606 one byte. Also fixes the meaning of len() so that it returns the number of
2607 items, rather than the size in bytes.
2608
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002609- Issue #4075: Use OutputDebugStringW in Py_FatalError.

2619
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002620- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2621 where the tp_hash and tp_dict slots are both NULL.
2622
Georg Brandlccc47b62008-12-28 11:44:14 +00002623- Issue #4759: None is now allowed as the first argument of

2996
Antoine Pitrou08838b62009-01-21 00:55:13 +00002997- Issue #5008: When a file is opened in append mode with the new IO library,
2998 do an explicit seek to the end of file (so that e.g. tell() returns the
2999 file size rather than 0). This is consistent with the behaviour of the
