11
12Core and Builtins
13-----------------
14
Mark Dickinsond59b4162010-03-13 11:34:40 +000015- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
16 PyMemberDefs could produce an internal error; raise TypeError instead.
17
Mark Dickinsonf673f0c2010-03-13 09:48:39 +000018- Issue #7845: Rich comparison methods on the complex type now return
19 NotImplemented rather than raising a TypeError when comparing with an
20 incompatible type; this allows user-defined classes to implement their own
21 comparisons with complex.
22
Victor Stinner52f6dd72010-03-12 14:45:56 +000023- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
24 (SIGINT). If an error occurs while importing the site module, the error is
25 printed and Python exits. Initialize the GIL before importing the site
26 module.
27
Benjamin Petersonae5f2f42010-03-07 17:10:51 +000028- Issue #7173: Generator finalization could invalidate sys.exc_info().
29
Victor Stinner45b9be52010-03-03 23:28:07 +000030- Issue #7544: Preallocate thread memory before creating the thread to avoid
31 a fatal error in low memory condition.
32
Victor Stinner6aa278e2010-03-03 00:18:49 +000033- Issue #7820: The parser tokenizer restores all bytes in the right if
34 the BOM check fails.
35
Benjamin Peterson23e018a2010-02-27 17:40:01 +000036- Handle errors from looking up __prepare__ correctly.
37
Larry Hastings1373a072010-02-24 22:49:58 +000038- Issue #5939: Add additional runtime checking to ensure a valid capsule
39 in Modules/_ctypes/callproc.c.
40
Eric Smith0facd772010-02-24 15:42:29 +000041- Issue #7309: Fix unchecked attribute access when converting
42 UnicodeEncodeError, UnicodeDecodeError, and UnicodeTranslateError to
43 strings.
44
Eric Smithabb28c62010-02-23 00:22:24 +000045- Issue #6902: Fix problem with built-in types format incorrectly with
46 0 padding.
47
Eric Smith4e260c52010-02-22 18:54:44 +000048- Issue #7988: Fix default alignment to be right aligned for
49 complex.__format__. Now it matches other numeric types.
50
Eric Smith68af50b2010-02-22 14:58:30 +000051- Issue #5988: Remove deprecated functions PyOS_ascii_formatd,
52 PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string
53 and PyOS_string_to_double instead. See issue #5835 for the original
54 deprecations.
55
Antoine Pitrou05b7c562010-02-02 22:47:00 +000056- Issue #7385: Fix a crash in `MemoryView_FromObject` when
57 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
58
Mark Dickinsonbc099642010-01-29 17:27:24 +000059- Issue #7788: Fix an interpreter crash produced by deleting a list
60 slice with very large step value.
61
Eric Smithf7bb5782010-01-27 00:44:57 +000062- Issue #7766: Change sys.getwindowsversion() return value to a named
63 tuple and add the additional members returned in an OSVERSIONINFOEX
64 structure. The new members are service_pack_major, service_pack_minor,
65 suite_mask, and product_type.
66
Antoine Pitroufc8d6f42010-01-17 12:38:54 +000067- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
68 could crash in many places because of the PyByteArray_AS_STRING() macro
69 returning NULL. The macro now returns a statically allocated empty
70 string instead.
71
Antoine Pitroub7fbcd32010-01-16 18:37:38 +000072- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
73 where the right hand operand is a set of constants, by turning the set into
74 a frozenset and pre-building it as a constant. The comparison operation
75 is made against the constant instead of building a new set each time it is
76 executed (a similar optimization already existed which turned a list of
77 constants into a pre-built tuple). Patch and additional tests by Dave
78 Malcolm.
79
Antoine Pitrouf2c54842010-01-13 08:07:53 +000080- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
81 methods of bytes, bytearray and unicode objects by using a common
82 implementation based on stringlib's fast search. Patch by Florent Xicluna.
83
Mark Dickinson45b63652010-01-16 18:10:25 +000084- Issue #7632: Fix various str -> float conversion bugs present in 2.7
85 alpha 2, including: (1) a serious 'wrong output' bug that could
86 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
87 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +000088 strings corresponding to subnormal values, (3) a memory leak for
89 some values large enough to cause overflow, and (4) a number of
90 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +000091
Benjamin Petersonaea44282010-01-04 01:10:28 +000092- The __complex__ method is now looked up on the class of instances to make it
93 consistent with other special methods.
94
Antoine Pitrouda2ecaf2010-01-02 21:40:36 +000095- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
96 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
97
Benjamin Petersond12362a2009-12-30 19:44:54 +000098- Issue #7604: Deleting an unset slotted attribute did not raise an
99 AttributeError.
100
Mark Dickinson9ab44b52009-12-30 16:22:49 +0000101- Issue #7534: Fix handling of IEEE specials (infinities, nans,
102 negative zero) in ** operator. The behaviour now conforms to that
103 described in C99 Annex F.
104
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000105- Issue #1811: improve accuracy and cross-platform consistency for
106 true division of integers: the result of a/b is now correctly
107 rounded for ints a and b (at least on IEEE 754 platforms), and in
108 particular does not depend on the internal representation of an int.
109
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000110- Issue #6834: replace the implementation for the 'python' and 'pythonw'
111 executables on OSX.
112
113 These executables now work properly with the arch(1) command:
114 ``arch -ppc python`` will start a universal binary version of python
115 in PPC mode (unlike previous releases).
116
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000117- Issue #7466: segmentation fault when the garbage collector is called
118 in the middle of populating a tuple. Patch by Florent Xicluna.

121 with invalid values.
122
Amaury Forgeot d'Arc7d0bddd2009-11-30 00:08:56 +0000123- Issue #6077: On Windows, files opened with tempfile.TemporaryFile in "wt+"
124 mode would appear truncated on the first '0x1a' byte (aka. Ctrl+Z).
125
Ronald Oussoren3c1928a2009-11-19 17:15:31 +0000126- Issue #7085: Fix crash when importing some extensions in a thread
127 on MacOSX 10.6.
128
Philip Jenvey1309adb2009-11-17 03:43:14 +0000129- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
130
Mark Dickinson6f1d0492009-11-15 13:58:49 +0000131- Issue #6970: Remove redundant calls when comparing objects that don't
132 implement the relevant rich comparison methods.
133
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000134- Issue #7298: fixes for range and reversed(range(...)). Iteration
135 over range(a, b, c) incorrectly gave an empty iterator when a, b and
136 c fit in C long but the length of the range did not. Also fix
137 several cases where reversed(range(a, b, c)) gave wrong results, and
138 fix a refleak for reversed(range(a, b, c)) with large arguments.
139
Raymond Hettingerfc438512009-11-01 20:55:33 +0000140- Issue #7244: itertools.izip_longest() no longer ignores exceptions
141 raised during the formation of an output tuple.
142
Benjamin Petersonb2e796a2009-10-28 21:59:39 +0000143- Issue #3297: On wide unicode builds, do not split unicode characters into
144 surrogates.

149
Antoine Pitroub6ef9632009-10-24 20:47:05 +0000150- Support for AtheOS has been completely removed from the code base. It was
151 disabled since Python 3.0.
152
153- Support for several legacy threading libraries has been disabled. These
154 libraries are: Mach C threads, SunOS LWP, GNU pth, Irix threads. Support code
155 will be entirely removed in 3.3.
156
Raymond Hettingeraf7adad2009-10-22 11:22:50 +0000157- Peephole constant folding had missed UNARY_POSITIVE.

170 There should be no other effect than a small decrease in memory use.
171 Patch by Christopher Tur Lesniewski-Laas.
172
Antoine Pitrou403ce782009-10-14 17:14:16 +0000173- Issue #7065: Fix a crash in bytes.maketrans and bytearray.maketrans when
Antoine Pitrou671141d2009-10-19 19:37:25 +0000174 using byte values greater than 127. Patch by Derk Drukker.
Antoine Pitrou403ce782009-10-14 17:14:16 +0000175
Amaury Forgeot d'Arc7d520792009-10-06 21:03:20 +0000176- Issue #1571184: The Unicode database contains properties for more characters.
177 The tables for code points representing numeric values, white spaces or line
178 breaks are now generated from the official Unicode Character Database files,
179 and include information from the Unihan.txt file.
180
Mark Dickinson2683ab02009-09-29 19:21:35 +0000181- Issue #7019: Raise ValueError when unmarshalling bad long data, instead
182 of producing internally inconsistent Python longs.

Amaury Forgeot d'Arc097cd072009-07-07 00:43:08 +0000210- Issue #6428: Since Python 3.0, the __bool__ method must return a bool
211 object, and not an int. Fix the corresponding error message, and the
212 documentation.
213
Benjamin Petersonf1664ae2009-07-01 01:28:55 +0000214- The deprecated PyCObject has been removed.

225
Alexandre Vassalottieb6f8de2009-12-31 03:56:09 +0000226- Issue #6687: PyBytes_FromObject() no longer accepts an integer as its
227 argument to construct a null-initialized bytes object.
228
Alexandre Vassalottic36c3782010-01-09 20:35:09 +0000229- Issue #1023290: Add from_bytes() and to_bytes() methods to integers.
230 These methods allow the conversion of integers to bytes, and vice-versa.
231

237-----
238
Mark Dickinson93f562c2010-01-30 10:30:15 +0000239- Issue #7767: New function PyLong_AsLongLongAndOverflow added,

246 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
247 PyArg_VaParseTupleAndKeywords and PyArg_Parse now raise a
248 DeprecationWarning for float arguments passed with the 'L' format
249 code. This will become a TypeError in a future version of Python,
250 to match the behaviour of the other integer format codes.
251
Georg Brandl1e28a272009-12-28 08:41:01 +0000252- Issue #7033: function ``PyErr_NewExceptionWithDoc()`` added.
253
Mark Dickinsonf08173b2009-12-03 10:59:46 +0000254- Issue #7414: 'C' code wasn't being skipped properly (for keyword arguments)
255 in PyArg_ParseTupleAndKeywords.

261 in PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be
262 should used for accessing the d_type and d_name members of structures
263 using PyDescr_COMMON.
264
265- Issue #6405: Remove duplicate type declarations in descrobject.h.
Benjamin Peterson89b89172009-07-03 13:30:25 +0000266
Benjamin Peterson466a7822009-07-02 21:44:01 +0000267- The code flags for old __future__ features are now available again.
268
Alexandre Vassalotti7b82b402009-07-21 04:30:03 +0000269- Issue #5954: Add a PyFrame_GetLineNumber() function to replace most uses of
270 PyCode_Addr2Line().

276 ``const char *`` as the string is stored beyond the call.
277
Benjamin Peterson05159c42009-12-03 03:01:27 +0000278- Issue #2422: When compiled with the ``--with-valgrind`` option, the
279 pymalloc allocator will be automatically disabled when running under
280 Valgrind. This gives improved memory leak detection when running
281 under Valgrind, while taking advantage of pymalloc at other times.

284-------
285
Benjamin Peterson689a5582010-03-18 22:29:52 +0000286- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
287 detected.
288
Florent Xicluna657de432010-03-18 22:11:01 +0000289- Issue #8024: Update the Unicode database to 5.2.

299 the locale.
300
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000301- The internals of the subprocess module on POSIX systems have been replaced
302 by an extension module (_posixsubprocess) so that the fork()+exec() can be
303 done safely without the possibility of deadlock in multithreaded applications.
304
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000305- subprocess.Popen now has restore_signals and start_new_session features.
306 The default of restore_signals=True is a new behavior compared to earlier
307 Python versions. This means that signals such as SIGPIPE are not ignored
308 by default in subprocesses launched by Python (Issue #1652).
309
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000310- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
311 cElementTree module is updated too.
312
Victor Stinnerb33062c2010-03-12 14:27:16 +0000313- Issue #7774: Set sys.executable to an empty string if argv[0] has been set to
314 an non existent program name and Python is unable to retrieve the real

401 :class:`zipfile.ZipExtFile` class used to represent files stored inside
402 an archive. The new implementation is significantly faster and can
403 be wrapped in a :class:`io.BufferedReader` object for more speedups.
404 It also solves an issue where interleaved calls to `read()` and
405 `readline()` give wrong results. Patch by Nir Aides.

567
Nick Coghlan260bd3e2009-11-16 06:49:25 +0000568- Issue #6816: runpy now provides a run_path function that allows Python code
569 to execute file paths that refer to source or compiled Python files as well
570 as zipfiles, directories and other valid sys.path entries that contain a
571 __main__.py file. This allows applications that run other Python scripts to
572 support the same flexibility as the CPython command line itself.
573
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000574- Issue #7318: multiprocessing now uses a timeout when it fails to establish
575 a connection with another process, rather than looping endlessly. The
576 default timeout is 20 seconds, which should be amply sufficient for
577 local connections.
578
Antoine Pitrouc63ecee2009-11-10 21:34:48 +0000579- Issue #7197: Allow unittest.TextTestRunner objects to be pickled and

591 default when instantiating a `threading.RLock` object. This makes
592 recursive locks as fast as regular non-recursive locks (previously,
593 they were slower by 10x to 15x).
594
Antoine Pitroub0872682009-11-09 16:08:16 +0000595- Issue #7282: Fix a memory leak when an RLock was used in a thread other

Antoine Pitrou03f13442009-11-02 11:36:51 +0000608- Issue #6896: mailbox.Maildir now invalidates its internal cache each time
609 a modification is done through it. This fixes inconsistencies and test
610 failures on systems with slightly bogus mtime behaviour.
611
Gregory P. Smith50467882009-11-01 18:42:17 +0000612- Issue #7246 & Issue #7208: getpass now properly flushes input before
613 reading from stdin so that existing input does not confuse it and
614 lead to incorrect entry or an IOError. It also properly flushes it
615 afterwards to avoid the terminal echoing the input afterwards on
616 OSes such as Solaris.
617
Mark Dickinsona2d1fe02009-10-29 12:23:02 +0000618- Issue #7233: Fix a number of two-argument Decimal methods to make

920
R. David Murray378c0cf2010-02-24 01:46:21 +0000921- Issue #6292: for the moment at least, the test suite runs cleanly if python

926 The original CWD is saved in `support.SAVEDCWD`.
927 Thanks to Florent Xicluna who helped with the patch.
928

935
R. David Murray445448c2009-12-20 17:28:31 +0000936- Issue #7376: instead of running a self-test (which was failing) when called

952 a test fails. Can be combined with -j.
953
Antoine Pitrou060cee22009-11-13 16:29:04 +0000954- Issue #6551: test_zipimport could import and then destroy some modules of
955 the encodings package, which would make other tests fail further down
956 the road because the internally cached encoders and decoders would point
957 to empty global variables.
958
Antoine Pitrou941ee882009-11-11 20:59:38 +0000959- Issue #7295: Do not use a hardcoded file name in test_tarfile.

965 tests instead of tempfile.tempdir. This prevents the tests from sharing state
966 between concurrent executions on the same system.
967
Brett Cannon0ae45112009-11-05 01:17:22 +0000968- Issue #7248: In importlib.test.source.util a try/finally block did not make
969 sure that some referenced objects actually were created in the block before
970 calling methods on the object.
971
Antoine Pitrou65c9c642009-10-30 17:25:12 +0000972- Issue #7222: Make thread "reaping" more reliable so that reference
973 leak-chasing test runs give sensible results. The previous method of
974 reaping threads could return successfully while some Thread objects were
975 still referenced. This also introduces a new private function:
976 :func:`_thread._count()`.
977
R. David Murray27144602009-10-19 15:26:16 +0000978- Issue #7151: fixed regrtest -j so that output to stderr from a test no
979 longer runs the risk of causing the worker thread to fail.
980
Antoine Pitrou4de39cd2009-10-10 21:08:31 +0000981- Issue #7055: test___all__ now greedily detects all modules which have an
982 __all__ attribute, rather than using a hardcoded and incomplete list.
983
R. David Murray0bc11ae2009-10-18 22:18:17 +0000984- Issue #7058: Added save/restore for things like sys.argv and cwd to

986 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +0000987
Mark Dickinson2e304402009-10-04 18:43:54 +0000988- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
989
Brett Cannon3c273842009-07-20 00:14:29 +0000990- Fixed tests in importlib.test.source.test_abc_loader that were masking
991 the proper exceptions that should be raised for missing or improper code
992 object bytecode.
993
Brett Cannonb49c70c2009-07-15 04:08:33 +0000994- Removed importlib's custom test discovery code and switched to

R. David Murray74b89242009-05-13 17:33:03 +00001214- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1215 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1216 corrects a pydoc regression.
1217
R. David Murray99352742009-05-07 18:24:38 +00001218- Issue 5955: aifc's close method did not close the file it wrapped,
1219 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00001257What's New in Python 3.1 beta 1?
1258================================
1259
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00001260*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001261
1262Core and Builtins
1263-----------------
1264
Mark Dickinson865e01a2009-05-07 16:37:01 +00001265- Issue #5914: Add new C API function PyOS_string_to_double, and
1266 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1267
Eric Smith741191f2009-05-06 13:08:15 +00001268- Issue #3382: float.__format__, complex.__format__, and %-formatting
1269 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1270 affects nan -> NAN and inf -> INF.
1271
Mark Hammond5a607a32009-05-06 08:04:54 +00001272- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1273 in all operations, including splitdrive, split, etc. splitunc() now issues
1274 a PendingDeprecation warning.
1275
Eric Smith63376222009-05-05 14:04:18 +00001276- Issue #5920: For float.__format__, change the behavior with the
1277 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1278 to be like 'g' but with at least one decimal point and with a
1279 default precision of 12. Previously, the behavior the same but with
1280 a default precision of 6. This more closely matches str(), and
1281 reduces surprises when adding alignment flags to the empty
1282 presentation type. This also affects the new complex.__format__ in
1283 the same way.
1284
Martin v. Löwis011e8422009-05-05 04:43:17 +00001285- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1286
R. David Murrayb18500d2009-05-04 22:59:07 +00001287- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1288 shadowed by classtype's, even if it was None. property now
1289 inserts the __doc__ into the subclass instance __dict__.
1290
Antoine Pitrou244651a2009-05-04 18:56:13 +00001291- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1292 sequences. Patch by Nick Barnes and Victor Stinner.
1293
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001294- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001295
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001296- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1297 received a new method, detach(). detach() disconnects the underlying stream
1298 from the buffer or text IO and returns it.
1299
Mark Dickinson33841c32009-05-01 15:37:04 +00001300- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1301 floats with absolute value over 1e50. Also remove length
1302 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1303 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001304
Eric Smith741191f2009-05-06 13:08:15 +00001305- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001306 format(complex(1, 2./3), '.5') now produces a sensible result.
1307
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001308- Issue #5864: Fix empty format code formatting for floats so that it
1309 never gives more than the requested number of significant digits.
1310
Eric Smith6dc46f52009-04-27 20:39:49 +00001311- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1312 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1313
Eric Smithcc32a112009-04-26 21:35:14 +00001314- Issue #5835: Deprecate PyOS_ascii_formatd.
1315
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001316- Issue #4971: Fix titlecase for characters that are their own
1317 titlecase, but not their own uppercase.
1318
Benjamin Peterson193152c2009-04-25 01:08:45 +00001319- Issue #5283: Setting __class__ in __del__ caused a segfault.
1320
Mark Dickinsonad476da2009-04-23 19:14:16 +00001321- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1322 z involves nans, infs or negative zeros.
1323
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001324- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001325
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001326- Issue #1869 (and many duplicates): make round(x, n) correctly
1327 rounded for a float x, by using the decimal <-> binary conversions
1328 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1329 consistently agrees with format(x, '.2f').
1330
Benjamin Petersonae937c02009-04-18 20:54:08 +00001331- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1332 some builtin types.
1333
Eric Smith0923d1d2009-04-16 20:16:10 +00001334- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1335
Eric Smith35e84722009-04-16 20:21:28 +00001336- Issue #5515: str.format() type 'n' combined with commas and leading
1337 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001338
1339- Implement PEP 378, Format Specifier for Thousands Separator, for
1340 floats.
1341
Mark Dickinson3370cce2009-04-17 22:40:53 +00001342- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001343 1e11, not 1e12. This avoids printing 13 significant digits in
1344 situations where only 12 of them are correct. Example problem
1345 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1346 long time.)
1347
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001348- Issue #1580: On most platforms, use a 'short' float repr: for a
1349 finite float x, repr(x) now outputs a string based on the shortest
1350 sequence of decimal digits that rounds to x. Previous behaviour was
1351 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001352 Another minor difference is that the new repr switches to
1353 exponential notation at 1e16 instead of the previous 1e17; this
1354 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001355
1356 There's a new sys attribute sys.float_repr_style, which takes
1357 the value 'short' to indicate that we're using short float repr,
1358 and 'legacy' if the short float repr isn't available for one
1359 reason or another.
1360
1361 The float repr change involves incorporating David Gay's 'perfect
1362 rounding' code into the Python core (it's in Python/dtoa.c). As a
1363 secondary consequence, all string-to-float and float-to-string
1364 conversions (including all float formatting operations) will be
1365 correctly rounded on these platforms.
1366
1367 See issue 1580 discussions for details of platforms for which
1368 this change does not apply.
1369
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001370- Issue #5759: float() didn't call __float__ on str subclasses.
1371
Georg Brandlabc38772009-04-12 15:51:51 +00001372- The string.maketrans() function is deprecated; there is a new static method
1373 maketrans() on the bytes and bytearray classes. This removes confusion about
1374 the types string.maketrans() is supposed to work with, and mirrors the
1375 methods available on the str class.
1376
R. David Murraydc6da8a2009-04-09 22:16:43 +00001377- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1378 its clarity and its speed.
1379
Matthias Klose091c7b12009-04-07 13:24:27 +00001380- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1381 to avoid compiler warnings.
1382
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001383- Issue #3739: The unicode-internal encoder now reports the number of characters
1384 consumed like any other encoder (instead of the number of bytes).

Benjamin Peterson8f76b492009-04-03 22:22:42 +00001519- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
1520
Benjamin Peterson7fe98532009-04-02 00:33:55 +00001521- Issue #5499: The 'c' code for argument parsing functions now only accepts a
1522 byte, and the 'C' code only accepts a unicode character.
1523
Georg Brandl406b3d82009-04-11 21:24:37 +00001524- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
1525 when hitting the recursion limit under certain circumstances.
1526
Brett Cannon0759dd62009-04-01 18:13:07 +00001527- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
1528
Georg Brandlab6f2f62009-03-31 04:16:10 +00001529- Fix a segfault when running test_exceptions with coverage, caused by
1530 insufficient checks in accessors of Exception.__context__.
1531
Guido van Rossum0ad59d42009-03-30 22:01:35 +00001532- Issue #5604: non-ASCII characters in module name passed to
1533 imp.find_module() were converted to UTF-8 while the path is
1534 converted to the default filesystem encoding, causing nonsense.
1535
Benjamin Peterson09832742009-03-26 17:15:46 +00001536- Issue #5126: str.isprintable() returned False for space characters.
1537
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00001538- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
1539 the end sys.path, for compatibility with the system install of Python.
1540
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001541- Issue #4688: Add a heuristic so that tuples and dicts containing only
1542 untrackable objects are not tracked by the garbage collector. This can
1543 reduce the size of collections and therefore the garbage collection overhead
1544 on long-running programs, depending on their particular use of datatypes.
1545
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001546- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
1547 improve its performance. Long divisions and remainder operations
1548 are now between 50% and 150% faster.
1549
Mark Dickinsonbd792642009-03-18 20:06:12 +00001550- Issue #4258: Make it possible to use base 2**30 instead of base
1551 2**15 for the internal representation of integers, for performance
1552 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1553 --enable-big-digits option to configure, which overrides the
1554 default. Add sys.int_info structseq to provide information about
1555 the internal format.
1556
Mark Dickinson081dfee2009-03-18 14:47:41 +00001557- Issue #4474: PyUnicode_FromWideChar now converts characters outside
1558 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1559 and sizeof(Py_UNICODE) == 2.
1560
Eric Smith8ec90442009-03-14 12:29:34 +00001561- Issue #5237: Allow auto-numbered fields in str.format(). For
1562 example: '{} {}'.format(1, 2) == '1 2'.
1563
Antoine Pitrou652e7072009-03-13 19:25:20 +00001564- Issue #5392: when a very low recursion limit was set, the interpreter would
1565 abort with a fatal error after the recursion limit was hit twice.
1566
Matthias Klose042f1332009-04-04 14:32:42 +00001567- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
1568 short file names.

1598
Brett Cannon7f6b4f82009-03-30 21:30:26 +00001599- Issue #5236: Change time.strptime() to only take strings. Didn't work with
1600 bytes already but the failure was non-obvious.
1601
Jesse Noller7af4ef82009-03-30 16:47:15 +00001602- Issue #5177: Multiprocessing's SocketListener class now uses

1609 (typically /dev/zero under Unix) could crash the interpreter.
1610
Benjamin Peterson59406a92009-03-26 17:10:29 +00001611- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and

1613
Lars Gustäbel42e00912009-03-22 20:34:29 +00001614- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1615 forever on incomplete input. That caused tarfile.open() to hang when used
1616 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1617 partial bzip2 compressed data.
1618
Mark Dickinson79f52032009-03-17 23:12:51 +00001619- Issue #2110: Add support for thousands separator and 'n' type

1637 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00001638 struct.error instead of returning b'\xff\xff\xff\xff'. The
1639 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
1640 have been removed from the struct module.

1659 contained non ascii character on windows.
1660
Benjamin Petersonf5b52242009-03-02 23:31:26 +00001661- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
1662 source has already been decoded into str.
1663
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00001664- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
1665 rotating the object pointer by 4 bits to the right.
1666
Mark Dickinson87ec0852009-02-09 17:15:59 +00001667- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1668 it now forces its argument to double before testing for infinity.
1669
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001670- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1671 returns a non-number type.
1672
Benjamin Peterson87618552009-02-08 15:00:52 +00001673- Issue #5182: Removed memoryview.__str__.

Mark Dickinsone94c6792009-02-02 20:36:42 +00001677 the type definition cmpfunc. The tp_compare slot has been renamed
1678 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001679
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001680- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001681 were suppressing all exceptions. These include list() and bytearray().
1682
Mark Dickinson1124e712009-01-28 21:25:58 +00001683- Issue #4707: round(x, n) now returns an integer if x is an integer.
1684 Previously it returned a float.
1685
Antoine Pitroub52ec782009-01-25 16:34:23 +00001686- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1687 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1688 evaluation loop is compiled with a new dispatch mechanism which gives
1689 speedups of up to 20%, depending on the system, on various benchmarks.
1690
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001691- Issue #4874: Most builtin decoders now reject unicode input.

1699 optional module state data.
1700
Mark Dickinson8055afd2009-01-17 10:04:45 +00001701- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1702 type to (void *).
1703
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001704- Issue #4935: The overflow checking code in the expandtabs() method common
1705 to str, bytes and bytearray could be optimized away by the compiler, letting
1706 the interpreter segfault instead of raising an error.
1707
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001708- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1709 __next__ method.
1710
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001711- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API

1718
Antoine Pitrouab868312009-01-10 15:40:25 +00001719- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1720 common cases are optimized thanks to a dedicated fast path and a moderate
1721 amount of loop unrolling.
1722
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001723- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1724 collecting the oldest generation) so that allocating lots of objects without
1725 destroying them does not show quadratic performance. Based on a proposal by
1726 Martin von Löwis at
1727 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1728
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001729- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001730 having been closed (for instance, a read() call could return some
1731 previously buffered data). Patch by Dmitry Vasiliev.
1732
Antoine Pitrou05608432009-01-09 18:53:14 +00001733- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1734 flag to work properly. Furthermore, when specifying -u, the text stdout
1735 and stderr streams have line-by-line buffering enabled (the default being
1736 to buffer arbitrary chunks of data).
1737
Raymond Hettinger35631532009-01-09 03:58:09 +00001738- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1739 instead of ints (reducing its size from 4 to 8 times thereby reducing
1740 Python's overall memory).
1741
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001742- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1743 an existing .py counterpart, override the co_filename attributes of all
1744 code objects if the original filename is obsolete (which can happen if the
1745 file has been renamed, moved, or if it is accessed through different paths).
1746 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1747
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001748- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1749 one byte. Also fixes the meaning of len() so that it returns the number of
1750 items, rather than the size in bytes.
1751
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001752- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1753
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001754- Issue #4747: When the terminal does not use utf-8, executing a script with
1755 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1756
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001757- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001758 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001759
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001760- Issue #3680: Reference cycles created through a dict, set or deque iterator
1761 did not get collected.
1762
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001763- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1764 where the tp_hash and tp_dict slots are both NULL.
1765
Georg Brandlccc47b62008-12-28 11:44:14 +00001766- Issue #4759: None is now allowed as the first argument of
1767 bytearray.translate(). It was always allowed for bytes.translate().
1768
Skip Montanaro80072cb2008-12-23 03:51:14 +00001769- Added test case to ensure attempts to read from a file opened for writing
1770 fail.

1776
Antoine Pitrou621601a2008-12-17 23:18:19 +00001777- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1778 print elapsed times, not only when some objects are uncollectable /
1779 unreachable. Original patch by Neil Schemenauer.
1780
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001781- Issue #3439: Add a bit_length method to int.
1782
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001783- Issue #2173: When getting device encoding, check that return value of
1784 nl_langinfo is not the empty string. This was causing silent build
1785 failures on OS X.
1786
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001787- Issue #4597: Fixed several opcodes that weren't always propagating
1788 exceptions.
1789
1790- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001791 context manager returns a value that cannot be converted to a bool.
1792
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001793- Issue #4445: Replace "sizeof(PyBytesObject)" with
1794 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1795 bytes instances. On a typical machine this saves 3 bytes of memory
1796 (on average) per allocation of a bytes instance.
1797
Christian Heimesa872de52008-12-05 08:26:55 +00001798- Issue #4533: File read operation was dreadfully slow due to a slowly
1799 growing read buffer. Fixed by using the same growth rate algorithm as

Antoine Pitrou08838b62009-01-21 00:55:13 +00002140- Issue #5008: When a file is opened in append mode with the new IO library,
2141 do an explicit seek to the end of file (so that e.g. tell() returns the
2142 file size rather than 0). This is consistent with the behaviour of the

Antoine Pitrou88909542009-06-29 13:54:42 +00002422- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
2423 regression tests in parallel, shortening the total runtime.
2424
Guilherme Polo2a998fa2009-06-21 17:40:07 +00002425- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2426 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2427 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2428 skip the tests if DISPLAY is defined but can't be used.
2429
R. David Murraya21e4ca2009-03-31 23:16:50 +00002430- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002431 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002432 from test support, which does the conversion.
2433
Guilherme Polo9de29af2009-01-28 20:40:48 +00002434- Issue #5083: New 'gui' resource for regrtest.
