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.
158
Antoine Pitrou011bd622009-10-20 21:52:47 +0000159- Issue #1722344: threading._shutdown() is now called in Py_Finalize(), which

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.

201
Raymond Hettingere805ecc2009-07-27 20:16:37 +0000202- Issue #6573: set.union() stopped processing inputs if an instance of self
203 occurred in the argument chain.
204
R. David Murray046f7232009-07-19 02:22:05 +0000205- Issue #6070: On posix platforms import no longer copies the execute bit
206 from the .py file to the .pyc file if it is set.

Mark Dickinson835a6c82009-06-30 15:45:17 +0000216- Issue #6347: Include inttypes.h as well as stdint.h in pyport.h.
217 This fixes a build failure on HP-UX: int32_t and uint32_t are
218 defined in inttypes.h instead of stdint.h on that platform.
219
Amaury Forgeot d'Arca4aba662009-07-01 00:48:39 +0000220- Issue #6373: Fixed a SystemError when encoding with the latin-1 codec and
Amaury Forgeot d'Arc84ec8d92009-06-29 22:36:49 +0000221 the 'surrogateescape' error handler, a string which contains unpaired
222 surrogates.

Hirokazu Yamamoto892a37a2009-06-28 11:07:03 +0000224- Issue #4856: Remove checks for win NT.
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.

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.

Mark Dickinsonf08173b2009-12-03 10:59:46 +0000254- Issue #7414: 'C' code wasn't being skipped properly (for keyword arguments)
255 in PyArg_ParseTupleAndKeywords.
256
Mark Dickinson0b2b2322009-12-04 11:32:26 +0000257- Issue #7228: Add '%lld' and '%llu' support to PyString_FromFormat(V)

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().

273 object at a specified file, function, and line number.
274
275- Issue #1419652: Change the first argument to PyImport_AppendInittab() to
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.

296 the locale.
297
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000298- The internals of the subprocess module on POSIX systems have been replaced
299 by an extension module (_posixsubprocess) so that the fork()+exec() can be
300 done safely without the possibility of deadlock in multithreaded applications.
301
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000302- subprocess.Popen now has restore_signals and start_new_session features.
303 The default of restore_signals=True is a new behavior compared to earlier
304 Python versions. This means that signals such as SIGPIPE are not ignored
305 by default in subprocesses launched by Python (Issue #1652).
306
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000307- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The

399 an archive. The new implementation is significantly faster and can
400 be wrapped in a :class:`io.BufferedReader` object for more speedups.
401 It also solves an issue where interleaved calls to `read()` and
402 `readline()` give wrong results. Patch by Nir Aides.

Nick Coghlan260bd3e2009-11-16 06:49:25 +0000565- Issue #6816: runpy now provides a run_path function that allows Python code
566 to execute file paths that refer to source or compiled Python files as well
567 as zipfiles, directories and other valid sys.path entries that contain a
568 __main__.py file. This allows applications that run other Python scripts to
569 support the same flexibility as the CPython command line itself.
570
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000571- Issue #7318: multiprocessing now uses a timeout when it fails to establish
572 a connection with another process, rather than looping endlessly. The

606 a modification is done through it. This fixes inconsistencies and test
607 failures on systems with slightly bogus mtime behaviour.
608
Gregory P. Smith50467882009-11-01 18:42:17 +0000609- Issue #7246 & Issue #7208: getpass now properly flushes input before
610 reading from stdin so that existing input does not confuse it and
611 lead to incorrect entry or an IOError. It also properly flushes it
612 afterwards to avoid the terminal echoing the input afterwards on
613 OSes such as Solaris.

916 filesystem encoding.
917
R. David Murray378c0cf2010-02-24 01:46:21 +0000918- Issue #6292: for the moment at least, the test suite runs cleanly if python
919 is run with the -OO flag. Tests requiring docstrings are skipped.
920
Ezio Melotti184bdfb2010-02-18 09:37:05 +0000921- Issue #7712: test.support gained a new `temp_cwd` context manager which is
922 now also used by regrtest to run all the tests in a temporary directory.
923 The original CWD is saved in `support.SAVEDCWD`.
924 Thanks to Florent Xicluna who helped with the patch.
925
Mark Dickinsonedff7af2010-02-13 18:34:53 +0000926- Issue #7924: Fix an intermittent 'XXX undetected error' failure in

932
R. David Murray445448c2009-12-20 17:28:31 +0000933- Issue #7376: instead of running a self-test (which was failing) when called

935
R. David Murrayef1992b2009-12-16 15:19:27 +0000936- Issue #7396: fix regrtest -s, which was broken by the -j enhancement.

943 user running the tests.
944
R. David Murray35768ad2009-11-15 00:23:21 +0000945- Issue #7324: add a sanity check to regrtest argument parsing to

949 a test fails. Can be combined with -j.
950
Antoine Pitrou060cee22009-11-13 16:29:04 +0000951- Issue #6551: test_zipimport could import and then destroy some modules of
952 the encodings package, which would make other tests fail further down
953 the road because the internally cached encoders and decoders would point
954 to empty global variables.
955
Antoine Pitrou941ee882009-11-11 20:59:38 +0000956- Issue #7295: Do not use a hardcoded file name in test_tarfile.

962 tests instead of tempfile.tempdir. This prevents the tests from sharing state
963 between concurrent executions on the same system.
964
Brett Cannon0ae45112009-11-05 01:17:22 +0000965- Issue #7248: In importlib.test.source.util a try/finally block did not make
966 sure that some referenced objects actually were created in the block before
967 calling methods on the object.
968
Antoine Pitrou65c9c642009-10-30 17:25:12 +0000969- Issue #7222: Make thread "reaping" more reliable so that reference
970 leak-chasing test runs give sensible results. The previous method of
971 reaping threads could return successfully while some Thread objects were
972 still referenced. This also introduces a new private function:
973 :func:`_thread._count()`.
974
R. David Murray27144602009-10-19 15:26:16 +0000975- Issue #7151: fixed regrtest -j so that output to stderr from a test no
976 longer runs the risk of causing the worker thread to fail.
977
Antoine Pitrou4de39cd2009-10-10 21:08:31 +0000978- Issue #7055: test___all__ now greedily detects all modules which have an
979 __all__ attribute, rather than using a hardcoded and incomplete list.
980
R. David Murray0bc11ae2009-10-18 22:18:17 +0000981- Issue #7058: Added save/restore for things like sys.argv and cwd to

983 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +0000984
Mark Dickinson2e304402009-10-04 18:43:54 +0000985- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
986
Brett Cannon3c273842009-07-20 00:14:29 +0000987- Fixed tests in importlib.test.source.test_abc_loader that were masking
988 the proper exceptions that should be raised for missing or improper code
989 object bytecode.
990
Brett Cannonb49c70c2009-07-15 04:08:33 +0000991- Removed importlib's custom test discovery code and switched to
992 unittest.TestLoader.discover().

995-----------
996
997- iobench (a file I/O benchmark) and ccbench (a concurrency benchmark) were
998 added to the `Tools/` directory. They were previously living in the

R. David Murray74b89242009-05-13 17:33:03 +00001211- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1212 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1213 corrects a pydoc regression.
1214
R. David Murray99352742009-05-07 18:24:38 +00001215- Issue 5955: aifc's close method did not close the file it wrapped,
1216 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00001254What's New in Python 3.1 beta 1?
1255================================
1256
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00001257*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001258
1259Core and Builtins
1260-----------------
1261
Mark Dickinson865e01a2009-05-07 16:37:01 +00001262- Issue #5914: Add new C API function PyOS_string_to_double, and
1263 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1264
Eric Smith741191f2009-05-06 13:08:15 +00001265- Issue #3382: float.__format__, complex.__format__, and %-formatting
1266 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1267 affects nan -> NAN and inf -> INF.
1268
Mark Hammond5a607a32009-05-06 08:04:54 +00001269- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1270 in all operations, including splitdrive, split, etc. splitunc() now issues
1271 a PendingDeprecation warning.
1272
Eric Smith63376222009-05-05 14:04:18 +00001273- Issue #5920: For float.__format__, change the behavior with the
1274 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1275 to be like 'g' but with at least one decimal point and with a
1276 default precision of 12. Previously, the behavior the same but with
1277 a default precision of 6. This more closely matches str(), and
1278 reduces surprises when adding alignment flags to the empty
1279 presentation type. This also affects the new complex.__format__ in
1280 the same way.
1281
Martin v. Löwis011e8422009-05-05 04:43:17 +00001282- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1283
R. David Murrayb18500d2009-05-04 22:59:07 +00001284- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1285 shadowed by classtype's, even if it was None. property now
1286 inserts the __doc__ into the subclass instance __dict__.
1287
Antoine Pitrou244651a2009-05-04 18:56:13 +00001288- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1289 sequences. Patch by Nick Barnes and Victor Stinner.
1290
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001291- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001292
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001293- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1294 received a new method, detach(). detach() disconnects the underlying stream
1295 from the buffer or text IO and returns it.
1296
Mark Dickinson33841c32009-05-01 15:37:04 +00001297- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1298 floats with absolute value over 1e50. Also remove length
1299 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1300 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001301
Eric Smith741191f2009-05-06 13:08:15 +00001302- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001303 format(complex(1, 2./3), '.5') now produces a sensible result.
1304
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001305- Issue #5864: Fix empty format code formatting for floats so that it
1306 never gives more than the requested number of significant digits.
1307
Eric Smith6dc46f52009-04-27 20:39:49 +00001308- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1309 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1310
Eric Smithcc32a112009-04-26 21:35:14 +00001311- Issue #5835: Deprecate PyOS_ascii_formatd.
1312
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001313- Issue #4971: Fix titlecase for characters that are their own
1314 titlecase, but not their own uppercase.
1315
Benjamin Peterson193152c2009-04-25 01:08:45 +00001316- Issue #5283: Setting __class__ in __del__ caused a segfault.
1317
Mark Dickinsonad476da2009-04-23 19:14:16 +00001318- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1319 z involves nans, infs or negative zeros.
1320
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001321- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001322
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001323- Issue #1869 (and many duplicates): make round(x, n) correctly
1324 rounded for a float x, by using the decimal <-> binary conversions
1325 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1326 consistently agrees with format(x, '.2f').
1327
Benjamin Petersonae937c02009-04-18 20:54:08 +00001328- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1329 some builtin types.
1330
Eric Smith0923d1d2009-04-16 20:16:10 +00001331- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1332
Eric Smith35e84722009-04-16 20:21:28 +00001333- Issue #5515: str.format() type 'n' combined with commas and leading
1334 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001335
1336- Implement PEP 378, Format Specifier for Thousands Separator, for
1337 floats.
1338
Mark Dickinson3370cce2009-04-17 22:40:53 +00001339- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001340 1e11, not 1e12. This avoids printing 13 significant digits in
1341 situations where only 12 of them are correct. Example problem
1342 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1343 long time.)
1344
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001345- Issue #1580: On most platforms, use a 'short' float repr: for a
1346 finite float x, repr(x) now outputs a string based on the shortest
1347 sequence of decimal digits that rounds to x. Previous behaviour was
1348 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001349 Another minor difference is that the new repr switches to
1350 exponential notation at 1e16 instead of the previous 1e17; this
1351 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001352
1353 There's a new sys attribute sys.float_repr_style, which takes
1354 the value 'short' to indicate that we're using short float repr,
1355 and 'legacy' if the short float repr isn't available for one
1356 reason or another.
1357
1358 The float repr change involves incorporating David Gay's 'perfect
1359 rounding' code into the Python core (it's in Python/dtoa.c). As a
1360 secondary consequence, all string-to-float and float-to-string
1361 conversions (including all float formatting operations) will be
1362 correctly rounded on these platforms.
1363
1364 See issue 1580 discussions for details of platforms for which
1365 this change does not apply.
1366
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001367- Issue #5759: float() didn't call __float__ on str subclasses.
1368
Georg Brandlabc38772009-04-12 15:51:51 +00001369- The string.maketrans() function is deprecated; there is a new static method
1370 maketrans() on the bytes and bytearray classes. This removes confusion about
1371 the types string.maketrans() is supposed to work with, and mirrors the
1372 methods available on the str class.
1373
R. David Murraydc6da8a2009-04-09 22:16:43 +00001374- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1375 its clarity and its speed.
1376
Matthias Klose091c7b12009-04-07 13:24:27 +00001377- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1378 to avoid compiler warnings.
1379
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001380- Issue #3739: The unicode-internal encoder now reports the number of characters
1381 consumed like any other encoder (instead of the number of bytes).

Benjamin Peterson8f76b492009-04-03 22:22:42 +00001516- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
1517
Benjamin Peterson7fe98532009-04-02 00:33:55 +00001518- Issue #5499: The 'c' code for argument parsing functions now only accepts a
1519 byte, and the 'C' code only accepts a unicode character.
1520
Georg Brandl406b3d82009-04-11 21:24:37 +00001521- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
1522 when hitting the recursion limit under certain circumstances.
1523
Brett Cannon0759dd62009-04-01 18:13:07 +00001524- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
1525
Georg Brandlab6f2f62009-03-31 04:16:10 +00001526- Fix a segfault when running test_exceptions with coverage, caused by
1527 insufficient checks in accessors of Exception.__context__.
1528
Guido van Rossum0ad59d42009-03-30 22:01:35 +00001529- Issue #5604: non-ASCII characters in module name passed to
1530 imp.find_module() were converted to UTF-8 while the path is
1531 converted to the default filesystem encoding, causing nonsense.
1532
Benjamin Peterson09832742009-03-26 17:15:46 +00001533- Issue #5126: str.isprintable() returned False for space characters.
1534
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00001535- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
1536 the end sys.path, for compatibility with the system install of Python.
1537
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001538- Issue #4688: Add a heuristic so that tuples and dicts containing only
1539 untrackable objects are not tracked by the garbage collector. This can
1540 reduce the size of collections and therefore the garbage collection overhead
1541 on long-running programs, depending on their particular use of datatypes.
1542
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001543- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
1544 improve its performance. Long divisions and remainder operations

1546
Mark Dickinsonbd792642009-03-18 20:06:12 +00001547- Issue #4258: Make it possible to use base 2**30 instead of base
1548 2**15 for the internal representation of integers, for performance
1549 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1550 --enable-big-digits option to configure, which overrides the
1551 default. Add sys.int_info structseq to provide information about
1552 the internal format.
1553
Mark Dickinson081dfee2009-03-18 14:47:41 +00001554- Issue #4474: PyUnicode_FromWideChar now converts characters outside
1555 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1556 and sizeof(Py_UNICODE) == 2.
1557
Eric Smith8ec90442009-03-14 12:29:34 +00001558- Issue #5237: Allow auto-numbered fields in str.format(). For
1559 example: '{} {}'.format(1, 2) == '1 2'.
1560
Antoine Pitrou652e7072009-03-13 19:25:20 +00001561- Issue #5392: when a very low recursion limit was set, the interpreter would
1562 abort with a fatal error after the recursion limit was hit twice.
1563
Matthias Klose042f1332009-04-04 14:32:42 +00001564- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

1610
Lars Gustäbel42e00912009-03-22 20:34:29 +00001611- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1612 forever on incomplete input. That caused tarfile.open() to hang when used
1613 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1614 partial bzip2 compressed data.

Mark Dickinson87ec0852009-02-09 17:15:59 +00001664- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1665 it now forces its argument to double before testing for infinity.
1666
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001667- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1668 returns a non-number type.
1669

1675 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001676
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001677- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001678 were suppressing all exceptions. These include list() and bytearray().
1679
Mark Dickinson1124e712009-01-28 21:25:58 +00001680- Issue #4707: round(x, n) now returns an integer if x is an integer.
1681 Previously it returned a float.
1682
Antoine Pitroub52ec782009-01-25 16:34:23 +00001683- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1684 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1685 evaluation loop is compiled with a new dispatch mechanism which gives
1686 speedups of up to 20%, depending on the system, on various benchmarks.
1687
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001688- Issue #4874: Most builtin decoders now reject unicode input.

Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001695- Issue #4838: When a module is deallocated, free the memory backing the
1696 optional module state data.
1697
Mark Dickinson8055afd2009-01-17 10:04:45 +00001698- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1699 type to (void *).
1700
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001701- Issue #4935: The overflow checking code in the expandtabs() method common
1702 to str, bytes and bytearray could be optimized away by the compiler, letting
1703 the interpreter segfault instead of raising an error.
1704
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001705- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1706 __next__ method.
1707
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001708- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API

1715
Antoine Pitrouab868312009-01-10 15:40:25 +00001716- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1717 common cases are optimized thanks to a dedicated fast path and a moderate
1718 amount of loop unrolling.
1719
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001720- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1721 collecting the oldest generation) so that allocating lots of objects without
1722 destroying them does not show quadratic performance. Based on a proposal by
1723 Martin von Löwis at
1724 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1725
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001726- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001727 having been closed (for instance, a read() call could return some
1728 previously buffered data). Patch by Dmitry Vasiliev.
1729
Antoine Pitrou05608432009-01-09 18:53:14 +00001730- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1731 flag to work properly. Furthermore, when specifying -u, the text stdout
1732 and stderr streams have line-by-line buffering enabled (the default being
1733 to buffer arbitrary chunks of data).
1734
Raymond Hettinger35631532009-01-09 03:58:09 +00001735- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1736 instead of ints (reducing its size from 4 to 8 times thereby reducing
1737 Python's overall memory).
1738
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001739- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1740 an existing .py counterpart, override the co_filename attributes of all
1741 code objects if the original filename is obsolete (which can happen if the
1742 file has been renamed, moved, or if it is accessed through different paths).
1743 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1744
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001745- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1746 one byte. Also fixes the meaning of len() so that it returns the number of
1747 items, rather than the size in bytes.
1748
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001749- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1750
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001751- Issue #4747: When the terminal does not use utf-8, executing a script with
1752 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1753
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001754- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001755 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001756
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001757- Issue #3680: Reference cycles created through a dict, set or deque iterator
1758 did not get collected.
1759
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001760- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1761 where the tp_hash and tp_dict slots are both NULL.
1762
Georg Brandlccc47b62008-12-28 11:44:14 +00001763- Issue #4759: None is now allowed as the first argument of
1764 bytearray.translate(). It was always allowed for bytes.translate().
1765
Skip Montanaro80072cb2008-12-23 03:51:14 +00001766- Added test case to ensure attempts to read from a file opened for writing
1767 fail.

1773
Antoine Pitrou621601a2008-12-17 23:18:19 +00001774- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1775 print elapsed times, not only when some objects are uncollectable /
1776 unreachable. Original patch by Neil Schemenauer.
1777
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001778- Issue #3439: Add a bit_length method to int.
1779
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001780- Issue #2173: When getting device encoding, check that return value of
1781 nl_langinfo is not the empty string. This was causing silent build
1782 failures on OS X.
1783
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001784- Issue #4597: Fixed several opcodes that weren't always propagating
1785 exceptions.
1786
1787- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001788 context manager returns a value that cannot be converted to a bool.
1789
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001790- Issue #4445: Replace "sizeof(PyBytesObject)" with
1791 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1792 bytes instances. On a typical machine this saves 3 bytes of memory
1793 (on average) per allocation of a bytes instance.
1794
Christian Heimesa872de52008-12-05 08:26:55 +00001795- Issue #4533: File read operation was dreadfully slow due to a slowly
1796 growing read buffer. Fixed by using the same growth rate algorithm as

2136
Antoine Pitrou08838b62009-01-21 00:55:13 +00002137- Issue #5008: When a file is opened in append mode with the new IO library,
2138 do an explicit seek to the end of file (so that e.g. tell() returns the
2139 file size rather than 0). This is consistent with the behaviour of the
2140 traditional 2.x file object.

2158
Jesse Noller6214edd2009-01-19 16:23:53 +00002159- Issue #3321: _multiprocessing.Connection() doesn't check handle; added checks

Antoine Pitrou88909542009-06-29 13:54:42 +00002419- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
2420 regression tests in parallel, shortening the total runtime.
2421
Guilherme Polo2a998fa2009-06-21 17:40:07 +00002422- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2423 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2424 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2425 skip the tests if DISPLAY is defined but can't be used.
2426
R. David Murraya21e4ca2009-03-31 23:16:50 +00002427- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002428 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002429 from test support, which does the conversion.
2430
Guilherme Polo9de29af2009-01-28 20:40:48 +00002431- Issue #5083: New 'gui' resource for regrtest.
