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

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

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

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

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

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.

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

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)

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.

285
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000286- The internals of the subprocess module on POSIX systems have been replaced
287 by an extension module (_posixsubprocess) so that the fork()+exec() can be
288 done safely without the possibility of deadlock in multithreaded applications.
289
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000290- subprocess.Popen now has restore_signals and start_new_session features.
291 The default of restore_signals=True is a new behavior compared to earlier
292 Python versions. This means that signals such as SIGPIPE are not ignored
293 by default in subprocesses launched by Python (Issue #1652).
294
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000295- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The

305 the replacement were all bytes. Patch by Antoine Pitrou.
306
Gerhard Häringf9cee222010-03-05 15:20:03 +0000307- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
308 bugs and allows loading SQLite extensions from shared libraries.
309
Victor Stinner7ed9c4c2010-03-04 12:14:57 +0000310- Issue #1054943: Fix unicodedata.normalize('NFC', text) for the Public Review

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

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

557 support the same flexibility as the CPython command line itself.
558
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000559- Issue #7318: multiprocessing now uses a timeout when it fails to establish

915
R. David Murray596da442009-12-14 23:06:11 +0000916- Issue #7498: test_multiprocessing now uses test.support.find_unused_port
R. David Murray83396232009-12-14 22:45:15 +0000917 instead of a hardcoded port number in test_rapid_restart.
918
R. David Murrayba311052009-12-04 00:09:14 +0000919- Issue #7431: use TESTFN in test_linecache instead of trying to create a
920 file in the Lib/test directory, which might be read-only for the
921 user running the tests.
922
R. David Murray35768ad2009-11-15 00:23:21 +0000923- Issue #7324: add a sanity check to regrtest argument parsing to

927 a test fails. Can be combined with -j.
928
Antoine Pitrou060cee22009-11-13 16:29:04 +0000929- Issue #6551: test_zipimport could import and then destroy some modules of
930 the encodings package, which would make other tests fail further down
931 the road because the internally cached encoders and decoders would point
932 to empty global variables.
933
Antoine Pitrou941ee882009-11-11 20:59:38 +0000934- Issue #7295: Do not use a hardcoded file name in test_tarfile.

941 between concurrent executions on the same system.
942
Brett Cannon0ae45112009-11-05 01:17:22 +0000943- Issue #7248: In importlib.test.source.util a try/finally block did not make
944 sure that some referenced objects actually were created in the block before
945 calling methods on the object.
946
Antoine Pitrou65c9c642009-10-30 17:25:12 +0000947- Issue #7222: Make thread "reaping" more reliable so that reference
948 leak-chasing test runs give sensible results. The previous method of
949 reaping threads could return successfully while some Thread objects were
950 still referenced. This also introduces a new private function:
951 :func:`_thread._count()`.
952
R. David Murray27144602009-10-19 15:26:16 +0000953- Issue #7151: fixed regrtest -j so that output to stderr from a test no
954 longer runs the risk of causing the worker thread to fail.
955
Antoine Pitrou4de39cd2009-10-10 21:08:31 +0000956- Issue #7055: test___all__ now greedily detects all modules which have an
957 __all__ attribute, rather than using a hardcoded and incomplete list.
958
R. David Murray0bc11ae2009-10-18 22:18:17 +0000959- Issue #7058: Added save/restore for things like sys.argv and cwd to

961 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +0000962
Mark Dickinson2e304402009-10-04 18:43:54 +0000963- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
964

Benjamin Petersonbd35b032009-04-04 23:16:41 +00001236
1237Core and Builtins
1238-----------------
1239
Mark Dickinson865e01a2009-05-07 16:37:01 +00001240- Issue #5914: Add new C API function PyOS_string_to_double, and
1241 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1242
Eric Smith741191f2009-05-06 13:08:15 +00001243- Issue #3382: float.__format__, complex.__format__, and %-formatting
1244 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1245 affects nan -> NAN and inf -> INF.
1246
Mark Hammond5a607a32009-05-06 08:04:54 +00001247- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1248 in all operations, including splitdrive, split, etc. splitunc() now issues
1249 a PendingDeprecation warning.
1250
Eric Smith63376222009-05-05 14:04:18 +00001251- Issue #5920: For float.__format__, change the behavior with the
1252 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1253 to be like 'g' but with at least one decimal point and with a
1254 default precision of 12. Previously, the behavior the same but with
1255 a default precision of 6. This more closely matches str(), and
1256 reduces surprises when adding alignment flags to the empty
1257 presentation type. This also affects the new complex.__format__ in
1258 the same way.
1259
Martin v. Löwis011e8422009-05-05 04:43:17 +00001260- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1261
R. David Murrayb18500d2009-05-04 22:59:07 +00001262- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1263 shadowed by classtype's, even if it was None. property now
1264 inserts the __doc__ into the subclass instance __dict__.
1265
Antoine Pitrou244651a2009-05-04 18:56:13 +00001266- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1267 sequences. Patch by Nick Barnes and Victor Stinner.
1268
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001269- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001270
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001271- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1272 received a new method, detach(). detach() disconnects the underlying stream
1273 from the buffer or text IO and returns it.
1274
Mark Dickinson33841c32009-05-01 15:37:04 +00001275- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1276 floats with absolute value over 1e50. Also remove length
1277 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1278 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001279
Eric Smith741191f2009-05-06 13:08:15 +00001280- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001281 format(complex(1, 2./3), '.5') now produces a sensible result.
1282
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001283- Issue #5864: Fix empty format code formatting for floats so that it
1284 never gives more than the requested number of significant digits.
1285
Eric Smith6dc46f52009-04-27 20:39:49 +00001286- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1287 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1288
Eric Smithcc32a112009-04-26 21:35:14 +00001289- Issue #5835: Deprecate PyOS_ascii_formatd.
1290
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001291- Issue #4971: Fix titlecase for characters that are their own
1292 titlecase, but not their own uppercase.
1293
Benjamin Peterson193152c2009-04-25 01:08:45 +00001294- Issue #5283: Setting __class__ in __del__ caused a segfault.
1295
Mark Dickinsonad476da2009-04-23 19:14:16 +00001296- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1297 z involves nans, infs or negative zeros.
1298
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001299- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001300
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001301- Issue #1869 (and many duplicates): make round(x, n) correctly
1302 rounded for a float x, by using the decimal <-> binary conversions
1303 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1304 consistently agrees with format(x, '.2f').
1305
Benjamin Petersonae937c02009-04-18 20:54:08 +00001306- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1307 some builtin types.
1308
Eric Smith0923d1d2009-04-16 20:16:10 +00001309- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1310
Eric Smith35e84722009-04-16 20:21:28 +00001311- Issue #5515: str.format() type 'n' combined with commas and leading
1312 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001313
1314- Implement PEP 378, Format Specifier for Thousands Separator, for
1315 floats.
1316
Mark Dickinson3370cce2009-04-17 22:40:53 +00001317- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001318 1e11, not 1e12. This avoids printing 13 significant digits in
1319 situations where only 12 of them are correct. Example problem
1320 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1321 long time.)
1322
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001323- Issue #1580: On most platforms, use a 'short' float repr: for a
1324 finite float x, repr(x) now outputs a string based on the shortest
1325 sequence of decimal digits that rounds to x. Previous behaviour was
1326 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001327 Another minor difference is that the new repr switches to
1328 exponential notation at 1e16 instead of the previous 1e17; this
1329 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001330
1331 There's a new sys attribute sys.float_repr_style, which takes
1332 the value 'short' to indicate that we're using short float repr,
1333 and 'legacy' if the short float repr isn't available for one
1334 reason or another.
1335
1336 The float repr change involves incorporating David Gay's 'perfect
1337 rounding' code into the Python core (it's in Python/dtoa.c). As a
1338 secondary consequence, all string-to-float and float-to-string
1339 conversions (including all float formatting operations) will be
1340 correctly rounded on these platforms.
1341
1342 See issue 1580 discussions for details of platforms for which
1343 this change does not apply.
1344
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001345- Issue #5759: float() didn't call __float__ on str subclasses.
1346
Georg Brandlabc38772009-04-12 15:51:51 +00001347- The string.maketrans() function is deprecated; there is a new static method
1348 maketrans() on the bytes and bytearray classes. This removes confusion about
1349 the types string.maketrans() is supposed to work with, and mirrors the
1350 methods available on the str class.
1351
R. David Murraydc6da8a2009-04-09 22:16:43 +00001352- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1353 its clarity and its speed.
1354
Matthias Klose091c7b12009-04-07 13:24:27 +00001355- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1356 to avoid compiler warnings.
1357
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001358- Issue #3739: The unicode-internal encoder now reports the number of characters
1359 consumed like any other encoder (instead of the number of bytes).

Antoine Pitrou3a652b12009-03-23 18:52:06 +00001516- Issue #4688: Add a heuristic so that tuples and dicts containing only
1517 untrackable objects are not tracked by the garbage collector. This can
1518 reduce the size of collections and therefore the garbage collection overhead
1519 on long-running programs, depending on their particular use of datatypes.
1520
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001521- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
1522 improve its performance. Long divisions and remainder operations
1523 are now between 50% and 150% faster.
1524
Mark Dickinsonbd792642009-03-18 20:06:12 +00001525- Issue #4258: Make it possible to use base 2**30 instead of base
1526 2**15 for the internal representation of integers, for performance
1527 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1528 --enable-big-digits option to configure, which overrides the
1529 default. Add sys.int_info structseq to provide information about
1530 the internal format.
1531
Mark Dickinson081dfee2009-03-18 14:47:41 +00001532- Issue #4474: PyUnicode_FromWideChar now converts characters outside

1534 and sizeof(Py_UNICODE) == 2.
1535
Eric Smith8ec90442009-03-14 12:29:34 +00001536- Issue #5237: Allow auto-numbered fields in str.format(). For

1538
Antoine Pitrou652e7072009-03-13 19:25:20 +00001539- Issue #5392: when a very low recursion limit was set, the interpreter would
1540 abort with a fatal error after the recursion limit was hit twice.
1541
Matthias Klose042f1332009-04-04 14:32:42 +00001542- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

1588
Lars Gustäbel42e00912009-03-22 20:34:29 +00001589- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1590 forever on incomplete input. That caused tarfile.open() to hang when used
1591 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or

1640 rotating the object pointer by 4 bits to the right.
1641
Mark Dickinson87ec0852009-02-09 17:15:59 +00001642- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1643 it now forces its argument to double before testing for infinity.
1644
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001645- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1646 returns a non-number type.
1647
Benjamin Peterson87618552009-02-08 15:00:52 +00001648- Issue #5182: Removed memoryview.__str__.

1653 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001654
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001655- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001656 were suppressing all exceptions. These include list() and bytearray().
1657
Mark Dickinson1124e712009-01-28 21:25:58 +00001658- Issue #4707: round(x, n) now returns an integer if x is an integer.
1659 Previously it returned a float.
1660
Antoine Pitroub52ec782009-01-25 16:34:23 +00001661- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1662 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1663 evaluation loop is compiled with a new dispatch mechanism which gives
1664 speedups of up to 20%, depending on the system, on various benchmarks.
1665
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001666- Issue #4874: Most builtin decoders now reject unicode input.

1672
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001673- Issue #4838: When a module is deallocated, free the memory backing the
1674 optional module state data.
1675
Mark Dickinson8055afd2009-01-17 10:04:45 +00001676- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1677 type to (void *).
1678
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001679- Issue #4935: The overflow checking code in the expandtabs() method common
1680 to str, bytes and bytearray could be optimized away by the compiler, letting
1681 the interpreter segfault instead of raising an error.
1682
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001683- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1684 __next__ method.
1685
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001686- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1687 function no longer attempt to call the __long__ slot to convert an object
1688 to an integer. Only the __int__ and __trunc__ slots are examined.
1689
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001690- Issue #4893: Use NT threading on CE.
1691
Martin v. Löwisec59d042009-01-12 07:59:10 +00001692- Issue #4915: Port sysmodule to Windows CE.
1693
Antoine Pitrouab868312009-01-10 15:40:25 +00001694- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1695 common cases are optimized thanks to a dedicated fast path and a moderate
1696 amount of loop unrolling.
1697
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001698- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1699 collecting the oldest generation) so that allocating lots of objects without
1700 destroying them does not show quadratic performance. Based on a proposal by
1701 Martin von Löwis at
1702 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1703
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001704- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001705 having been closed (for instance, a read() call could return some
1706 previously buffered data). Patch by Dmitry Vasiliev.
1707
Antoine Pitrou05608432009-01-09 18:53:14 +00001708- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1709 flag to work properly. Furthermore, when specifying -u, the text stdout
1710 and stderr streams have line-by-line buffering enabled (the default being
1711 to buffer arbitrary chunks of data).
1712
Raymond Hettinger35631532009-01-09 03:58:09 +00001713- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1714 instead of ints (reducing its size from 4 to 8 times thereby reducing
1715 Python's overall memory).
1716
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001717- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1718 an existing .py counterpart, override the co_filename attributes of all
1719 code objects if the original filename is obsolete (which can happen if the
1720 file has been renamed, moved, or if it is accessed through different paths).
1721 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1722
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001723- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1724 one byte. Also fixes the meaning of len() so that it returns the number of
1725 items, rather than the size in bytes.
1726
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001727- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1728
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001729- Issue #4747: When the terminal does not use utf-8, executing a script with
1730 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1731
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001732- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001733 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001734
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001735- Issue #3680: Reference cycles created through a dict, set or deque iterator
1736 did not get collected.
1737
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001738- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1739 where the tp_hash and tp_dict slots are both NULL.
1740
Georg Brandlccc47b62008-12-28 11:44:14 +00001741- Issue #4759: None is now allowed as the first argument of
1742 bytearray.translate(). It was always allowed for bytes.translate().
1743
Skip Montanaro80072cb2008-12-23 03:51:14 +00001744- Added test case to ensure attempts to read from a file opened for writing
1745 fail.
1746
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001747- Issue #3106: Speedup some comparisons (str/str and int/int).

1750 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1751
Antoine Pitrou621601a2008-12-17 23:18:19 +00001752- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1753 print elapsed times, not only when some objects are uncollectable /
1754 unreachable. Original patch by Neil Schemenauer.
1755
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001756- Issue #3439: Add a bit_length method to int.
1757
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001758- Issue #2173: When getting device encoding, check that return value of
1759 nl_langinfo is not the empty string. This was causing silent build
1760 failures on OS X.
1761
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001762- Issue #4597: Fixed several opcodes that weren't always propagating
1763 exceptions.
1764
1765- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001766 context manager returns a value that cannot be converted to a bool.
1767
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001768- Issue #4445: Replace "sizeof(PyBytesObject)" with
1769 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1770 bytes instances. On a typical machine this saves 3 bytes of memory
1771 (on average) per allocation of a bytes instance.
1772
Christian Heimesa872de52008-12-05 08:26:55 +00001773- Issue #4533: File read operation was dreadfully slow due to a slowly
1774 growing read buffer. Fixed by using the same growth rate algorithm as
1775 Python 2.x.
1776
Antoine Pitrou5504e892008-12-06 21:27:53 +00001777- Issue #4509: Various issues surrounding resize of bytearray objects to
1778 which there are buffer exports (e.g. memoryview instances).
1779
Georg Brandlf9734072008-12-07 15:30:06 +00001780- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1781 method on file objects with closefd=False. The file descriptor is still
1782 kept open but the file object behaves like a closed file. The ``FileIO``
1783 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001784
Antoine Pitroubc420402008-12-07 20:14:49 +00001785- Issue #4569: Interpreter crash when mutating a memoryview with an item size
1786 larger than 1.

1791
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001792- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1793 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1794 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1795 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou31f30b12009-01-02 17:34:35 +00002376- Issue #4738: Each zlib object now has a separate lock, allowing to compress
2377 or decompress several streams at once on multi-CPU systems. Also, the GIL
2378 is now released when computing the CRC of a large buffer. Patch by ebfe.

Antoine Pitrou88909542009-06-29 13:54:42 +00002397- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
2398 regression tests in parallel, shortening the total runtime.
2399
Guilherme Polo2a998fa2009-06-21 17:40:07 +00002400- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2401 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2402 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2403 skip the tests if DISPLAY is defined but can't be used.
2404
R. David Murraya21e4ca2009-03-31 23:16:50 +00002405- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002406 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002407 from test support, which does the conversion.
2408
Guilherme Polo9de29af2009-01-28 20:40:48 +00002409- Issue #5083: New 'gui' resource for regrtest.
