11
12Core and Builtins
13-----------------
14
Mark Dickinsoncbb62742009-12-27 15:09:50 +000015- Issue #1811: improve accuracy and cross-platform consistency for
16 true division of integers: the result of a/b is now correctly
17 rounded for ints a and b (at least on IEEE 754 platforms), and in
18 particular does not depend on the internal representation of an int.
19
Ronald Oussoren6f6c5622009-12-24 14:03:19 +000020- Issue #6834: replace the implementation for the 'python' and 'pythonw'
21 executables on OSX.
22
23 These executables now work properly with the arch(1) command:
24 ``arch -ppc python`` will start a universal binary version of python
25 in PPC mode (unlike previous releases).
26
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +000027- Issue #7466: segmentation fault when the garbage collector is called
28 in the middle of populating a tuple. Patch by Florent Xicluna.
29

42 implement the relevant rich comparison methods.
43
Mark Dickinsond550c9a2009-11-15 09:57:26 +000044- Issue #7298: fixes for range and reversed(range(...)). Iteration
45 over range(a, b, c) incorrectly gave an empty iterator when a, b and
46 c fit in C long but the length of the range did not. Also fix
47 several cases where reversed(range(a, b, c)) gave wrong results, and
48 fix a refleak for reversed(range(a, b, c)) with large arguments.
49
Raymond Hettingerfc438512009-11-01 20:55:33 +000050- Issue #7244: itertools.izip_longest() no longer ignores exceptions

158 object at a specified file, function, and line number.
159
160- Issue #1419652: Change the first argument to PyImport_AppendInittab() to
161 ``const char *`` as the string is stored beyond the call.

Alexandre Vassalotti2db046d2009-07-22 03:56:36 +0000163
Benjamin Peterson05159c42009-12-03 03:01:27 +0000164- Issue #2422: When compiled with the ``--with-valgrind`` option, the
165 pymalloc allocator will be automatically disabled when running under
166 Valgrind. This gives improved memory leak detection when running
167 under Valgrind, while taking advantage of pymalloc at other times.

267
Nick Coghlan260bd3e2009-11-16 06:49:25 +0000268- Issue #6816: runpy now provides a run_path function that allows Python code
269 to execute file paths that refer to source or compiled Python files as well
270 as zipfiles, directories and other valid sys.path entries that contain a
271 __main__.py file. This allows applications that run other Python scripts to
272 support the same flexibility as the CPython command line itself.
273
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000274- Issue #7318: multiprocessing now uses a timeout when it fails to establish

285 recursive locks as fast as regular non-recursive locks (previously,
286 they were slower by 10x to 15x).
287
Antoine Pitroub0872682009-11-09 16:08:16 +0000288- Issue #7282: Fix a memory leak when an RLock was used in a thread other

302 a modification is done through it. This fixes inconsistencies and test
303 failures on systems with slightly bogus mtime behaviour.
304
Gregory P. Smith50467882009-11-01 18:42:17 +0000305- Issue #7246 & Issue #7208: getpass now properly flushes input before
306 reading from stdin so that existing input does not confuse it and
307 lead to incorrect entry or an IOError. It also properly flushes it
308 afterwards to avoid the terminal echoing the input afterwards on
309 OSes such as Solaris.
310
Mark Dickinsona2d1fe02009-10-29 12:23:02 +0000311- Issue #7233: Fix a number of two-argument Decimal methods to make

858Core and Builtins
859-----------------
860
Mark Dickinson865e01a2009-05-07 16:37:01 +0000861- Issue #5914: Add new C API function PyOS_string_to_double, and
862 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
863
Eric Smith741191f2009-05-06 13:08:15 +0000864- Issue #3382: float.__format__, complex.__format__, and %-formatting
865 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
866 affects nan -> NAN and inf -> INF.
867
Mark Hammond5a607a32009-05-06 08:04:54 +0000868- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
869 in all operations, including splitdrive, split, etc. splitunc() now issues
870 a PendingDeprecation warning.
871
Eric Smith63376222009-05-05 14:04:18 +0000872- Issue #5920: For float.__format__, change the behavior with the
873 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
874 to be like 'g' but with at least one decimal point and with a
875 default precision of 12. Previously, the behavior the same but with
876 a default precision of 6. This more closely matches str(), and
877 reduces surprises when adding alignment flags to the empty
878 presentation type. This also affects the new complex.__format__ in
879 the same way.

Benjamin Petersond2e0c792009-05-01 20:40:59 +0000892- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
893 received a new method, detach(). detach() disconnects the underlying stream
894 from the buffer or text IO and returns it.
895
Mark Dickinson33841c32009-05-01 15:37:04 +0000896- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
897 floats with absolute value over 1e50. Also remove length
898 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
899 12.34 no longer raise an exception.

Mark Dickinsonad476da2009-04-23 19:14:16 +0000917- Issue #5816: complex(repr(z)) now recovers z exactly, even when
918 z involves nans, infs or negative zeros.
919
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000920- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000921
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000922- Issue #1869 (and many duplicates): make round(x, n) correctly
923 rounded for a float x, by using the decimal <-> binary conversions
924 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
925 consistently agrees with format(x, '.2f').
926
Benjamin Petersonae937c02009-04-18 20:54:08 +0000927- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
928 some builtin types.
929
Eric Smith0923d1d2009-04-16 20:16:10 +0000930- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
931
Eric Smith35e84722009-04-16 20:21:28 +0000932- Issue #5515: str.format() type 'n' combined with commas and leading
933 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000934
935- Implement PEP 378, Format Specifier for Thousands Separator, for
936 floats.
937
Mark Dickinson3370cce2009-04-17 22:40:53 +0000938- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000939 1e11, not 1e12. This avoids printing 13 significant digits in
940 situations where only 12 of them are correct. Example problem
941 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
942 long time.)
943
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000944- Issue #1580: On most platforms, use a 'short' float repr: for a
945 finite float x, repr(x) now outputs a string based on the shortest
946 sequence of decimal digits that rounds to x. Previous behaviour was
947 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000948 Another minor difference is that the new repr switches to
949 exponential notation at 1e16 instead of the previous 1e17; this
950 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000951
952 There's a new sys attribute sys.float_repr_style, which takes
953 the value 'short' to indicate that we're using short float repr,
954 and 'legacy' if the short float repr isn't available for one
955 reason or another.
956
957 The float repr change involves incorporating David Gay's 'perfect
958 rounding' code into the Python core (it's in Python/dtoa.c). As a
959 secondary consequence, all string-to-float and float-to-string
960 conversions (including all float formatting operations) will be
961 correctly rounded on these platforms.
962
963 See issue 1580 discussions for details of platforms for which
964 this change does not apply.
965
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000966- Issue #5759: float() didn't call __float__ on str subclasses.
967
Georg Brandlabc38772009-04-12 15:51:51 +0000968- The string.maketrans() function is deprecated; there is a new static method
969 maketrans() on the bytes and bytearray classes. This removes confusion about
970 the types string.maketrans() is supposed to work with, and mirrors the
971 methods available on the str class.
972
R. David Murraydc6da8a2009-04-09 22:16:43 +0000973- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

978
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000979- Issue #3739: The unicode-internal encoder now reports the number of characters

1136
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001137- Issue #4688: Add a heuristic so that tuples and dicts containing only
1138 untrackable objects are not tracked by the garbage collector. This can
1139 reduce the size of collections and therefore the garbage collection overhead
1140 on long-running programs, depending on their particular use of datatypes.

1154 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1155 and sizeof(Py_UNICODE) == 2.
1156
Eric Smith8ec90442009-03-14 12:29:34 +00001157- Issue #5237: Allow auto-numbered fields in str.format(). For

1206
Benjamin Peterson59406a92009-03-26 17:10:29 +00001207- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and
1208 io.BufferedRandom have been deprecated for removal in Python 3.2.
1209
Lars Gustäbel42e00912009-03-22 20:34:29 +00001210- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1211 forever on incomplete input. That caused tarfile.open() to hang when used
1212 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1213 partial bzip2 compressed data.

1233 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00001234 struct.error instead of returning b'\xff\xff\xff\xff'. The
1235 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
1236 have been removed from the struct module.

1252 used when using str.format() with str, int, and float arguments.
1253
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00001254- Issue #5249: time.strftime returned malformed string when format string
1255 contained non ascii character on windows.
1256
Benjamin Petersonf5b52242009-03-02 23:31:26 +00001257- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
1258 source has already been decoded into str.
1259
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00001260- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
1261 rotating the object pointer by 4 bits to the right.
1262
Mark Dickinson87ec0852009-02-09 17:15:59 +00001263- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1264 it now forces its argument to double before testing for infinity.
1265
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001266- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1267 returns a non-number type.
1268
Benjamin Peterson87618552009-02-08 15:00:52 +00001269- Issue #5182: Removed memoryview.__str__.

1274 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001275
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001276- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001277 were suppressing all exceptions. These include list() and bytearray().
1278
Mark Dickinson1124e712009-01-28 21:25:58 +00001279- Issue #4707: round(x, n) now returns an integer if x is an integer.
1280 Previously it returned a float.
1281
Antoine Pitroub52ec782009-01-25 16:34:23 +00001282- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1283 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1284 evaluation loop is compiled with a new dispatch mechanism which gives
1285 speedups of up to 20%, depending on the system, on various benchmarks.
1286
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001287- Issue #4874: Most builtin decoders now reject unicode input.

1290 from a string.
1291
Benjamin Peterson05e782f2009-01-19 15:15:02 +00001292- Issue #4991: os.fdopen now raises an OSError for invalid file descriptors.
1293
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001294- Issue #4838: When a module is deallocated, free the memory backing the
1295 optional module state data.
1296
Mark Dickinson8055afd2009-01-17 10:04:45 +00001297- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1298 type to (void *).
1299
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001300- Issue #4935: The overflow checking code in the expandtabs() method common
1301 to str, bytes and bytearray could be optimized away by the compiler, letting
1302 the interpreter segfault instead of raising an error.
1303
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001304- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1305 __next__ method.
1306
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001307- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1308 function no longer attempt to call the __long__ slot to convert an object
1309 to an integer. Only the __int__ and __trunc__ slots are examined.
1310
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001311- Issue #4893: Use NT threading on CE.
1312
Martin v. Löwisec59d042009-01-12 07:59:10 +00001313- Issue #4915: Port sysmodule to Windows CE.
1314
Antoine Pitrouab868312009-01-10 15:40:25 +00001315- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1316 common cases are optimized thanks to a dedicated fast path and a moderate
1317 amount of loop unrolling.
1318
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001319- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1320 collecting the oldest generation) so that allocating lots of objects without
1321 destroying them does not show quadratic performance. Based on a proposal by
1322 Martin von Löwis at
1323 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1324
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001325- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001326 having been closed (for instance, a read() call could return some
1327 previously buffered data). Patch by Dmitry Vasiliev.
1328
Antoine Pitrou05608432009-01-09 18:53:14 +00001329- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1330 flag to work properly. Furthermore, when specifying -u, the text stdout
1331 and stderr streams have line-by-line buffering enabled (the default being
1332 to buffer arbitrary chunks of data).
1333
Raymond Hettinger35631532009-01-09 03:58:09 +00001334- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1335 instead of ints (reducing its size from 4 to 8 times thereby reducing
1336 Python's overall memory).
1337
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001338- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1339 an existing .py counterpart, override the co_filename attributes of all
1340 code objects if the original filename is obsolete (which can happen if the
1341 file has been renamed, moved, or if it is accessed through different paths).
1342 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1343
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001344- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1345 one byte. Also fixes the meaning of len() so that it returns the number of
1346 items, rather than the size in bytes.
1347
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001348- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1349
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001350- Issue #4747: When the terminal does not use utf-8, executing a script with
1351 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1352
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001353- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001354 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001355
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001356- Issue #3680: Reference cycles created through a dict, set or deque iterator
1357 did not get collected.
1358
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001359- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1360 where the tp_hash and tp_dict slots are both NULL.
1361
Georg Brandlccc47b62008-12-28 11:44:14 +00001362- Issue #4759: None is now allowed as the first argument of
1363 bytearray.translate(). It was always allowed for bytes.translate().
1364
Skip Montanaro80072cb2008-12-23 03:51:14 +00001365- Added test case to ensure attempts to read from a file opened for writing
1366 fail.
1367
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001368- Issue #3106: Speedup some comparisons (str/str and int/int).

1372
Antoine Pitrou621601a2008-12-17 23:18:19 +00001373- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1374 print elapsed times, not only when some objects are uncollectable /
1375 unreachable. Original patch by Neil Schemenauer.
1376
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001377- Issue #3439: Add a bit_length method to int.
1378
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001379- Issue #2173: When getting device encoding, check that return value of
1380 nl_langinfo is not the empty string. This was causing silent build
1381 failures on OS X.
1382
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001383- Issue #4597: Fixed several opcodes that weren't always propagating
1384 exceptions.
1385
1386- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001387 context manager returns a value that cannot be converted to a bool.
1388
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001389- Issue #4445: Replace "sizeof(PyBytesObject)" with
1390 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1391 bytes instances. On a typical machine this saves 3 bytes of memory
1392 (on average) per allocation of a bytes instance.
1393
Christian Heimesa872de52008-12-05 08:26:55 +00001394- Issue #4533: File read operation was dreadfully slow due to a slowly
1395 growing read buffer. Fixed by using the same growth rate algorithm as
1396 Python 2.x.
1397
Antoine Pitrou5504e892008-12-06 21:27:53 +00001398- Issue #4509: Various issues surrounding resize of bytearray objects to
1399 which there are buffer exports (e.g. memoryview instances).
1400
Georg Brandlf9734072008-12-07 15:30:06 +00001401- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1402 method on file objects with closefd=False. The file descriptor is still
1403 kept open but the file object behaves like a closed file. The ``FileIO``
1404 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001405
Antoine Pitroubc420402008-12-07 20:14:49 +00001406- Issue #4569: Interpreter crash when mutating a memoryview with an item size
1407 larger than 1.

1412
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001413- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1414 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1415 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1416 of using the replace error handler in PyUnicode_DecodeUTF8().
