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

158
Antoine Pitrou011bd622009-10-20 21:52:47 +0000159- Issue #1722344: threading._shutdown() is now called in Py_Finalize(), which
160 fixes the problem of some exceptions being thrown at shutdown when the
161 interpreter is killed. Patch by Adam Olsen.
162
Antoine Pitrou671141d2009-10-19 19:37:25 +0000163- Issue #7147: Remove support for compiling Python without complex number

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.
183
Philip Jenvey26713ca2009-09-29 04:57:18 +0000184- Issue #6990: Fix threading.local subclasses leaving old state around
185 after a reference cycle GC which could be recycled by new locals.
186
Benjamin Peterson4905e802009-09-27 02:43:28 +0000187- Issue #5460: Fix an ambiguity in the grammar.

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

212 documentation.
213
Benjamin Petersonf1664ae2009-07-01 01:28:55 +0000214- The deprecated PyCObject has been removed.
215
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.
223
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

237-----
238
Mark Dickinson93f562c2010-01-30 10:30:15 +0000239- Issue #7767: New function PyLong_AsLongLongAndOverflow added,
240 analogous to PyLong_AsLongAndOverflow.
241
Benjamin Peterson8667a9b2010-01-09 21:45:28 +0000242- Make PyUnicode_CompareWithASCIIString return not equal if the Python string
243 has '\0' at the end.
244
Mark Dickinsonde604012010-01-01 19:27:32 +0000245- Issue #5080: The argument parsing functions PyArg_ParseTuple,
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.
256
Mark Dickinson0b2b2322009-12-04 11:32:26 +0000257- Issue #7228: Add '%lld' and '%llu' support to PyString_FromFormat(V)

259
Alexandre Vassalotti2db046d2009-07-22 03:56:36 +0000260- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD
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().
271
272- Issue #5959: Add a PyCode_NewEmpty() function to create a new empty code
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.

Matthias Klosea6d9abf2010-03-16 10:51:28 +0000286- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
287 with Tcl/Tk-8.5.
288
Matthias Klosec33b9022010-03-16 00:36:26 +0000289- Issue #8140: extend compileall to compile single files. Add -i option.

Matthias Klose82f60912010-03-15 13:46:04 +0000291- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
292 the locale.
293
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000294- The internals of the subprocess module on POSIX systems have been replaced
295 by an extension module (_posixsubprocess) so that the fork()+exec() can be
296 done safely without the possibility of deadlock in multithreaded applications.
297
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000298- subprocess.Popen now has restore_signals and start_new_session features.
299 The default of restore_signals=True is a new behavior compared to earlier
300 Python versions. This means that signals such as SIGPIPE are not ignored
301 by default in subprocesses launched by Python (Issue #1652).
302
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000303- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
304 cElementTree module is updated too.

307 an non existent program name and Python is unable to retrieve the real
308 program name
309
Florent Xiclunaa4707382010-03-11 00:05:17 +0000310- Issue #7880: Fix sysconfig when the python executable is a symbolic link.
311
Ezio Melottib92ed7c2010-03-06 15:24:08 +0000312- Issue #6509: fix re.sub to work properly when the pattern, the string, and
313 the replacement were all bytes. Patch by Antoine Pitrou.
314

397 It also solves an issue where interleaved calls to `read()` and
398 `readline()` give wrong results. Patch by Nir Aides.

562 to execute file paths that refer to source or compiled Python files as well
563 as zipfiles, directories and other valid sys.path entries that contain a

565 support the same flexibility as the CPython command line itself.
566
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000567- Issue #7318: multiprocessing now uses a timeout when it fails to establish

R. David Murray378c0cf2010-02-24 01:46:21 +0000913- Issue #6292: for the moment at least, the test suite runs cleanly if python
914 is run with the -OO flag. Tests requiring docstrings are skipped.
915
Ezio Melotti184bdfb2010-02-18 09:37:05 +0000916- Issue #7712: test.support gained a new `temp_cwd` context manager which is
917 now also used by regrtest to run all the tests in a temporary directory.
918 The original CWD is saved in `support.SAVEDCWD`.
919 Thanks to Florent Xicluna who helped with the patch.
920
Mark Dickinsonedff7af2010-02-13 18:34:53 +0000921- Issue #7924: Fix an intermittent 'XXX undetected error' failure in
922 test_capi (only seen so far on platforms where the curses module
923 wasn't built), due to an uncleared exception.
924
R. David Murraye9e95932010-02-06 05:00:15 +0000925- issue #7728: test_timeout was changed to use test_support.bind_port
926 instead of a hard coded port.
927
R. David Murray445448c2009-12-20 17:28:31 +0000928- Issue #7376: instead of running a self-test (which was failing) when called
929 with no arguments, doctest.py now gives a usage message.
930
R. David Murrayef1992b2009-12-16 15:19:27 +0000931- Issue #7396: fix regrtest -s, which was broken by the -j enhancement.
932
R. David Murray596da442009-12-14 23:06:11 +0000933- Issue #7498: test_multiprocessing now uses test.support.find_unused_port

935
R. David Murrayba311052009-12-04 00:09:14 +0000936- Issue #7431: use TESTFN in test_linecache instead of trying to create a
937 file in the Lib/test directory, which might be read-only for the
938 user running the tests.
939
R. David Murray35768ad2009-11-15 00:23:21 +0000940- Issue #7324: add a sanity check to regrtest argument parsing to
941 catch the case of an option with no handler.
942
R. David Murray7dc72cc2009-11-14 16:13:02 +0000943- Issue #7312: Add a -F flag to run the selected tests in a loop until
944 a test fails. Can be combined with -j.
945
Antoine Pitrou060cee22009-11-13 16:29:04 +0000946- Issue #6551: test_zipimport could import and then destroy some modules of
947 the encodings package, which would make other tests fail further down
948 the road because the internally cached encoders and decoders would point
949 to empty global variables.
950
Antoine Pitrou941ee882009-11-11 20:59:38 +0000951- Issue #7295: Do not use a hardcoded file name in test_tarfile.

955
Brett Cannoncfed0292009-11-05 01:26:57 +0000956- Issue #7248 (part 2): Use a unique temporary directory for importlib source
957 tests instead of tempfile.tempdir. This prevents the tests from sharing state
958 between concurrent executions on the same system.
959
Brett Cannon0ae45112009-11-05 01:17:22 +0000960- Issue #7248: In importlib.test.source.util a try/finally block did not make
961 sure that some referenced objects actually were created in the block before
962 calling methods on the object.
963
Antoine Pitrou65c9c642009-10-30 17:25:12 +0000964- Issue #7222: Make thread "reaping" more reliable so that reference
965 leak-chasing test runs give sensible results. The previous method of
966 reaping threads could return successfully while some Thread objects were
967 still referenced. This also introduces a new private function:
968 :func:`_thread._count()`.
969
R. David Murray27144602009-10-19 15:26:16 +0000970- Issue #7151: fixed regrtest -j so that output to stderr from a test no
971 longer runs the risk of causing the worker thread to fail.
972
Antoine Pitrou4de39cd2009-10-10 21:08:31 +0000973- Issue #7055: test___all__ now greedily detects all modules which have an
974 __all__ attribute, rather than using a hardcoded and incomplete list.
975
R. David Murray0bc11ae2009-10-18 22:18:17 +0000976- Issue #7058: Added save/restore for things like sys.argv and cwd to
977 runtest_inner in regrtest, with warnings if the called test modifies them,
978 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +0000979
Mark Dickinson2e304402009-10-04 18:43:54 +0000980- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
981
Brett Cannon3c273842009-07-20 00:14:29 +0000982- Fixed tests in importlib.test.source.test_abc_loader that were masking
983 the proper exceptions that should be raised for missing or improper code
984 object bytecode.
985
Brett Cannonb49c70c2009-07-15 04:08:33 +0000986- Removed importlib's custom test discovery code and switched to
987 unittest.TestLoader.discover().

990-----------
991
992- iobench (a file I/O benchmark) and ccbench (a concurrency benchmark) were

Benjamin Petersonbd35b032009-04-04 23:16:41 +00001249What's New in Python 3.1 beta 1?
1250================================
1251
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00001252*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001253
1254Core and Builtins
1255-----------------
1256
Mark Dickinson865e01a2009-05-07 16:37:01 +00001257- Issue #5914: Add new C API function PyOS_string_to_double, and
1258 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1259
Eric Smith741191f2009-05-06 13:08:15 +00001260- Issue #3382: float.__format__, complex.__format__, and %-formatting
1261 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1262 affects nan -> NAN and inf -> INF.
1263
Mark Hammond5a607a32009-05-06 08:04:54 +00001264- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1265 in all operations, including splitdrive, split, etc. splitunc() now issues
1266 a PendingDeprecation warning.
1267
Eric Smith63376222009-05-05 14:04:18 +00001268- Issue #5920: For float.__format__, change the behavior with the
1269 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1270 to be like 'g' but with at least one decimal point and with a
1271 default precision of 12. Previously, the behavior the same but with
1272 a default precision of 6. This more closely matches str(), and
1273 reduces surprises when adding alignment flags to the empty
1274 presentation type. This also affects the new complex.__format__ in
1275 the same way.
1276
Martin v. Löwis011e8422009-05-05 04:43:17 +00001277- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1278
R. David Murrayb18500d2009-05-04 22:59:07 +00001279- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1280 shadowed by classtype's, even if it was None. property now
1281 inserts the __doc__ into the subclass instance __dict__.
1282
Antoine Pitrou244651a2009-05-04 18:56:13 +00001283- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1284 sequences. Patch by Nick Barnes and Victor Stinner.
1285
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001286- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001287
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001288- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1289 received a new method, detach(). detach() disconnects the underlying stream
1290 from the buffer or text IO and returns it.
1291
Mark Dickinson33841c32009-05-01 15:37:04 +00001292- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1293 floats with absolute value over 1e50. Also remove length
1294 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1295 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001296
Eric Smith741191f2009-05-06 13:08:15 +00001297- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001298 format(complex(1, 2./3), '.5') now produces a sensible result.
1299
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001300- Issue #5864: Fix empty format code formatting for floats so that it
1301 never gives more than the requested number of significant digits.
1302
Eric Smith6dc46f52009-04-27 20:39:49 +00001303- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1304 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1305
Eric Smithcc32a112009-04-26 21:35:14 +00001306- Issue #5835: Deprecate PyOS_ascii_formatd.
1307
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001308- Issue #4971: Fix titlecase for characters that are their own
1309 titlecase, but not their own uppercase.
1310
Benjamin Peterson193152c2009-04-25 01:08:45 +00001311- Issue #5283: Setting __class__ in __del__ caused a segfault.
1312
Mark Dickinsonad476da2009-04-23 19:14:16 +00001313- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1314 z involves nans, infs or negative zeros.
1315
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001316- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001317
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001318- Issue #1869 (and many duplicates): make round(x, n) correctly
1319 rounded for a float x, by using the decimal <-> binary conversions
1320 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1321 consistently agrees with format(x, '.2f').
1322
Benjamin Petersonae937c02009-04-18 20:54:08 +00001323- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1324 some builtin types.
1325
Eric Smith0923d1d2009-04-16 20:16:10 +00001326- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1327
Eric Smith35e84722009-04-16 20:21:28 +00001328- Issue #5515: str.format() type 'n' combined with commas and leading
1329 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001330
1331- Implement PEP 378, Format Specifier for Thousands Separator, for
1332 floats.
1333
Mark Dickinson3370cce2009-04-17 22:40:53 +00001334- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001335 1e11, not 1e12. This avoids printing 13 significant digits in
1336 situations where only 12 of them are correct. Example problem
1337 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1338 long time.)
1339
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001340- Issue #1580: On most platforms, use a 'short' float repr: for a
1341 finite float x, repr(x) now outputs a string based on the shortest
1342 sequence of decimal digits that rounds to x. Previous behaviour was
1343 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001344 Another minor difference is that the new repr switches to
1345 exponential notation at 1e16 instead of the previous 1e17; this
1346 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001347
1348 There's a new sys attribute sys.float_repr_style, which takes
1349 the value 'short' to indicate that we're using short float repr,
1350 and 'legacy' if the short float repr isn't available for one
1351 reason or another.
1352
1353 The float repr change involves incorporating David Gay's 'perfect
1354 rounding' code into the Python core (it's in Python/dtoa.c). As a
1355 secondary consequence, all string-to-float and float-to-string
1356 conversions (including all float formatting operations) will be
1357 correctly rounded on these platforms.
1358
1359 See issue 1580 discussions for details of platforms for which
1360 this change does not apply.
1361
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001362- Issue #5759: float() didn't call __float__ on str subclasses.
1363
Georg Brandlabc38772009-04-12 15:51:51 +00001364- The string.maketrans() function is deprecated; there is a new static method
1365 maketrans() on the bytes and bytearray classes. This removes confusion about
1366 the types string.maketrans() is supposed to work with, and mirrors the
1367 methods available on the str class.
1368
R. David Murraydc6da8a2009-04-09 22:16:43 +00001369- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1370 its clarity and its speed.
1371
Matthias Klose091c7b12009-04-07 13:24:27 +00001372- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1373 to avoid compiler warnings.
1374
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001375- Issue #3739: The unicode-internal encoder now reports the number of characters
1376 consumed like any other encoder (instead of the number of bytes).

Brett Cannon0759dd62009-04-01 18:13:07 +00001519- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
1520
Georg Brandlab6f2f62009-03-31 04:16:10 +00001521- Fix a segfault when running test_exceptions with coverage, caused by
1522 insufficient checks in accessors of Exception.__context__.
1523
Guido van Rossum0ad59d42009-03-30 22:01:35 +00001524- Issue #5604: non-ASCII characters in module name passed to
1525 imp.find_module() were converted to UTF-8 while the path is
1526 converted to the default filesystem encoding, causing nonsense.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00001530- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
1531 the end sys.path, for compatibility with the system install of Python.
1532
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001533- Issue #4688: Add a heuristic so that tuples and dicts containing only
1534 untrackable objects are not tracked by the garbage collector. This can
1535 reduce the size of collections and therefore the garbage collection overhead
1536 on long-running programs, depending on their particular use of datatypes.
1537
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001538- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
1539 improve its performance. Long divisions and remainder operations
1540 are now between 50% and 150% faster.
1541
Mark Dickinsonbd792642009-03-18 20:06:12 +00001542- Issue #4258: Make it possible to use base 2**30 instead of base
1543 2**15 for the internal representation of integers, for performance
1544 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1545 --enable-big-digits option to configure, which overrides the
1546 default. Add sys.int_info structseq to provide information about
1547 the internal format.
1548
Mark Dickinson081dfee2009-03-18 14:47:41 +00001549- Issue #4474: PyUnicode_FromWideChar now converts characters outside
1550 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1551 and sizeof(Py_UNICODE) == 2.
1552
Eric Smith8ec90442009-03-14 12:29:34 +00001553- Issue #5237: Allow auto-numbered fields in str.format(). For

1555
Antoine Pitrou652e7072009-03-13 19:25:20 +00001556- Issue #5392: when a very low recursion limit was set, the interpreter would
1557 abort with a fatal error after the recursion limit was hit twice.
1558
Matthias Klose042f1332009-04-04 14:32:42 +00001559- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

1605
Lars Gustäbel42e00912009-03-22 20:34:29 +00001606- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1607 forever on incomplete input. That caused tarfile.open() to hang when used
1608 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or

1657 rotating the object pointer by 4 bits to the right.
1658
Mark Dickinson87ec0852009-02-09 17:15:59 +00001659- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1660 it now forces its argument to double before testing for infinity.
1661
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001662- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1663 returns a non-number type.
1664
Benjamin Peterson87618552009-02-08 15:00:52 +00001665- Issue #5182: Removed memoryview.__str__.

1670 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001671
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001672- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001673 were suppressing all exceptions. These include list() and bytearray().
1674
Mark Dickinson1124e712009-01-28 21:25:58 +00001675- Issue #4707: round(x, n) now returns an integer if x is an integer.
1676 Previously it returned a float.
1677
Antoine Pitroub52ec782009-01-25 16:34:23 +00001678- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1679 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1680 evaluation loop is compiled with a new dispatch mechanism which gives
1681 speedups of up to 20%, depending on the system, on various benchmarks.
1682
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001683- Issue #4874: Most builtin decoders now reject unicode input.

1689
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001690- Issue #4838: When a module is deallocated, free the memory backing the
1691 optional module state data.
1692
Mark Dickinson8055afd2009-01-17 10:04:45 +00001693- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1694 type to (void *).
1695
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001696- Issue #4935: The overflow checking code in the expandtabs() method common
1697 to str, bytes and bytearray could be optimized away by the compiler, letting
1698 the interpreter segfault instead of raising an error.
1699
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001700- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1701 __next__ method.
1702
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001703- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API

1710
Antoine Pitrouab868312009-01-10 15:40:25 +00001711- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1712 common cases are optimized thanks to a dedicated fast path and a moderate
1713 amount of loop unrolling.
1714
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001715- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1716 collecting the oldest generation) so that allocating lots of objects without
1717 destroying them does not show quadratic performance. Based on a proposal by
1718 Martin von Löwis at
1719 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1720
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001721- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001722 having been closed (for instance, a read() call could return some
1723 previously buffered data). Patch by Dmitry Vasiliev.
1724
Antoine Pitrou05608432009-01-09 18:53:14 +00001725- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1726 flag to work properly. Furthermore, when specifying -u, the text stdout
1727 and stderr streams have line-by-line buffering enabled (the default being
1728 to buffer arbitrary chunks of data).
1729
Raymond Hettinger35631532009-01-09 03:58:09 +00001730- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1731 instead of ints (reducing its size from 4 to 8 times thereby reducing
1732 Python's overall memory).
1733
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001734- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1735 an existing .py counterpart, override the co_filename attributes of all
1736 code objects if the original filename is obsolete (which can happen if the
1737 file has been renamed, moved, or if it is accessed through different paths).
1738 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1739
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001740- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1741 one byte. Also fixes the meaning of len() so that it returns the number of
1742 items, rather than the size in bytes.
1743
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001744- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1745
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001746- Issue #4747: When the terminal does not use utf-8, executing a script with
1747 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1748
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001749- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001750 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001751
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001752- Issue #3680: Reference cycles created through a dict, set or deque iterator
1753 did not get collected.
1754
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001755- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1756 where the tp_hash and tp_dict slots are both NULL.
1757
Georg Brandlccc47b62008-12-28 11:44:14 +00001758- Issue #4759: None is now allowed as the first argument of
1759 bytearray.translate(). It was always allowed for bytes.translate().
1760
Skip Montanaro80072cb2008-12-23 03:51:14 +00001761- Added test case to ensure attempts to read from a file opened for writing
1762 fail.
1763
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001764- Issue #3106: Speedup some comparisons (str/str and int/int).

1767 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1768
Antoine Pitrou621601a2008-12-17 23:18:19 +00001769- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1770 print elapsed times, not only when some objects are uncollectable /
1771 unreachable. Original patch by Neil Schemenauer.
1772
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001773- Issue #3439: Add a bit_length method to int.
1774
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001775- Issue #2173: When getting device encoding, check that return value of
1776 nl_langinfo is not the empty string. This was causing silent build
1777 failures on OS X.
1778
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001779- Issue #4597: Fixed several opcodes that weren't always propagating
1780 exceptions.
1781
1782- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001783 context manager returns a value that cannot be converted to a bool.
1784
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001785- Issue #4445: Replace "sizeof(PyBytesObject)" with
1786 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1787 bytes instances. On a typical machine this saves 3 bytes of memory
1788 (on average) per allocation of a bytes instance.
1789
Christian Heimesa872de52008-12-05 08:26:55 +00001790- Issue #4533: File read operation was dreadfully slow due to a slowly
1791 growing read buffer. Fixed by using the same growth rate algorithm as
1792 Python 2.x.
1793
Antoine Pitrou5504e892008-12-06 21:27:53 +00001794- Issue #4509: Various issues surrounding resize of bytearray objects to
1795 which there are buffer exports (e.g. memoryview instances).
1796
Georg Brandlf9734072008-12-07 15:30:06 +00001797- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1798 method on file objects with closefd=False. The file descriptor is still
1799 kept open but the file object behaves like a closed file. The ``FileIO``

2131
Antoine Pitrou08838b62009-01-21 00:55:13 +00002132- Issue #5008: When a file is opened in append mode with the new IO library,
2133 do an explicit seek to the end of file (so that e.g. tell() returns the
2134 file size rather than 0). This is consistent with the behaviour of the
2135 traditional 2.x file object.

2153
Jesse Noller6214edd2009-01-19 16:23:53 +00002154- Issue #3321: _multiprocessing.Connection() doesn't check handle; added checks

2165 appropriately when it is being used via socket.makefile() objects
2166 rather than delaying the close by waiting for garbage collection to do it.
2167

2380 supporting objects as input no matter how it was compiled (built in
2381 implementations or external openssl library).
2382
Mark Dickinson29500f62009-01-15 15:36:10 +00002383- Issue #4397: Fix occasional test_socket failure on OS X.

2386
Antoine Pitroubcd5cbe2009-01-08 21:17:16 +00002387- Issue #4751: hashlib now releases the GIL when hashing large buffers
2388 (with a hardwired threshold of 2048 bytes), allowing better parallelization
2389 on multi-CPU systems. Contributed by Lukas Lueg (ebfe) and Victor Stinner.
2390
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002391- Issue #4051: Prevent conflict of UNICODE macros in cPickle.
2392
Antoine Pitrou31f30b12009-01-02 17:34:35 +00002393- Issue #4738: Each zlib object now has a separate lock, allowing to compress
2394 or decompress several streams at once on multi-CPU systems. Also, the GIL
2395 is now released when computing the CRC of a large buffer. Patch by ebfe.
2396
Georg Brandlb1441c72009-01-03 22:33:39 +00002397- Issue #4228: Pack negative values the same way as 2.4 in struct's L format.

2402 OpenBSD.
Amaury Forgeot d'Arcefae8c42008-11-21 23:08:09 +00002403
Antoine Pitrou3ad3a0d2008-12-18 17:08:32 +00002404- Issue #4583: array.array would not always prohibit resizing when a buffer
2405 has been exported, resulting in an interpreter crash when accessing the
2406 buffer.
2407
Martin v. Löwis841edad2008-11-30 10:36:49 +00002408
Jack Diederiche0cbd692009-04-01 04:27:09 +00002409- Issue #5228: Make functools.partial objects can now be pickled.

2413
Antoine Pitrou88909542009-06-29 13:54:42 +00002414- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
2415 regression tests in parallel, shortening the total runtime.
2416
Guilherme Polo2a998fa2009-06-21 17:40:07 +00002417- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2418 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2419 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2420 skip the tests if DISPLAY is defined but can't be used.
2421
R. David Murraya21e4ca2009-03-31 23:16:50 +00002422- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002423 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002424 from test support, which does the conversion.
2425
Guilherme Polo9de29af2009-01-28 20:40:48 +00002426- Issue #5083: New 'gui' resource for regrtest.
