12Core and Builtins
13-----------------
14
Antoine Pitrouf2c54842010-01-13 08:07:53 +000015- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
16 methods of bytes, bytearray and unicode objects by using a common
17 implementation based on stringlib's fast search. Patch by Florent Xicluna.
18
Mark Dickinson81612e82010-01-12 23:04:19 +000019- Issue #7632: Fix a crash in dtoa.c that occurred in debug builds
20 when parsing certain long numeric strings corresponding to subnormal
21 values. Also fix a number of bugs in dtoa.c that could lead to
22 incorrectly rounded results when converting strings to floats.
23
Benjamin Petersonaea44282010-01-04 01:10:28 +000024- The __complex__ method is now looked up on the class of instances to make it
25 consistent with other special methods.
26
Antoine Pitrouda2ecaf2010-01-02 21:40:36 +000027- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
28 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
29

35 described in C99 Annex F.
36
Mark Dickinsoncbb62742009-12-27 15:09:50 +000037- Issue #1811: improve accuracy and cross-platform consistency for
38 true division of integers: the result of a/b is now correctly
39 rounded for ints a and b (at least on IEEE 754 platforms), and in
40 particular does not depend on the internal representation of an int.
41
Ronald Oussoren6f6c5622009-12-24 14:03:19 +000042- Issue #6834: replace the implementation for the 'python' and 'pythonw'
43 executables on OSX.

46 ``arch -ppc python`` will start a universal binary version of python
47 in PPC mode (unlike previous releases).
48

65
Mark Dickinsond550c9a2009-11-15 09:57:26 +000066- Issue #7298: fixes for range and reversed(range(...)). Iteration
67 over range(a, b, c) incorrectly gave an empty iterator when a, b and
68 c fit in C long but the length of the range did not. Also fix
69 several cases where reversed(range(a, b, c)) gave wrong results, and
70 fix a refleak for reversed(range(a, b, c)) with large arguments.

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

388 reading from stdin so that existing input does not confuse it and
389 lead to incorrect entry or an IOError. It also properly flushes it

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000951
952Core and Builtins
953-----------------
954
Mark Dickinson865e01a2009-05-07 16:37:01 +0000955- Issue #5914: Add new C API function PyOS_string_to_double, and
956 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
957
Eric Smith741191f2009-05-06 13:08:15 +0000958- Issue #3382: float.__format__, complex.__format__, and %-formatting
959 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
960 affects nan -> NAN and inf -> INF.
961
Mark Hammond5a607a32009-05-06 08:04:54 +0000962- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
963 in all operations, including splitdrive, split, etc. splitunc() now issues
964 a PendingDeprecation warning.
965
Eric Smith63376222009-05-05 14:04:18 +0000966- Issue #5920: For float.__format__, change the behavior with the
967 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
968 to be like 'g' but with at least one decimal point and with a
969 default precision of 12. Previously, the behavior the same but with
970 a default precision of 6. This more closely matches str(), and
971 reduces surprises when adding alignment flags to the empty
972 presentation type. This also affects the new complex.__format__ in
973 the same way.
974
Martin v. Löwis011e8422009-05-05 04:43:17 +0000975- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
976
R. David Murrayb18500d2009-05-04 22:59:07 +0000977- Issue #5890: in subclasses of 'property' the __doc__ attribute was
978 shadowed by classtype's, even if it was None. property now
979 inserts the __doc__ into the subclass instance __dict__.
980
Antoine Pitrou244651a2009-05-04 18:56:13 +0000981- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
982 sequences. Patch by Nick Barnes and Victor Stinner.
983
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000984- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000985
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000986- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
987 received a new method, detach(). detach() disconnects the underlying stream
988 from the buffer or text IO and returns it.
989
Mark Dickinson33841c32009-05-01 15:37:04 +0000990- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
991 floats with absolute value over 1e50. Also remove length
992 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
993 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000994
Eric Smith741191f2009-05-06 13:08:15 +0000995- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000996 format(complex(1, 2./3), '.5') now produces a sensible result.
997
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000998- Issue #5864: Fix empty format code formatting for floats so that it
999 never gives more than the requested number of significant digits.
1000
Eric Smith6dc46f52009-04-27 20:39:49 +00001001- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1002 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1003
Eric Smithcc32a112009-04-26 21:35:14 +00001004- Issue #5835: Deprecate PyOS_ascii_formatd.
1005
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001006- Issue #4971: Fix titlecase for characters that are their own
1007 titlecase, but not their own uppercase.
1008
Benjamin Peterson193152c2009-04-25 01:08:45 +00001009- Issue #5283: Setting __class__ in __del__ caused a segfault.
1010
Mark Dickinsonad476da2009-04-23 19:14:16 +00001011- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1012 z involves nans, infs or negative zeros.
1013
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001014- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001015
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001016- Issue #1869 (and many duplicates): make round(x, n) correctly
1017 rounded for a float x, by using the decimal <-> binary conversions
1018 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1019 consistently agrees with format(x, '.2f').
1020
Benjamin Petersonae937c02009-04-18 20:54:08 +00001021- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1022 some builtin types.
1023
Eric Smith0923d1d2009-04-16 20:16:10 +00001024- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1025
Eric Smith35e84722009-04-16 20:21:28 +00001026- Issue #5515: str.format() type 'n' combined with commas and leading
1027 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001028
1029- Implement PEP 378, Format Specifier for Thousands Separator, for
1030 floats.
1031
Mark Dickinson3370cce2009-04-17 22:40:53 +00001032- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001033 1e11, not 1e12. This avoids printing 13 significant digits in
1034 situations where only 12 of them are correct. Example problem
1035 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1036 long time.)
1037
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001038- Issue #1580: On most platforms, use a 'short' float repr: for a
1039 finite float x, repr(x) now outputs a string based on the shortest
1040 sequence of decimal digits that rounds to x. Previous behaviour was
1041 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001042 Another minor difference is that the new repr switches to
1043 exponential notation at 1e16 instead of the previous 1e17; this
1044 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001045
1046 There's a new sys attribute sys.float_repr_style, which takes
1047 the value 'short' to indicate that we're using short float repr,
1048 and 'legacy' if the short float repr isn't available for one
1049 reason or another.
1050
1051 The float repr change involves incorporating David Gay's 'perfect
1052 rounding' code into the Python core (it's in Python/dtoa.c). As a
1053 secondary consequence, all string-to-float and float-to-string
1054 conversions (including all float formatting operations) will be
1055 correctly rounded on these platforms.
1056
1057 See issue 1580 discussions for details of platforms for which
1058 this change does not apply.
1059
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001060- Issue #5759: float() didn't call __float__ on str subclasses.
1061
Georg Brandlabc38772009-04-12 15:51:51 +00001062- The string.maketrans() function is deprecated; there is a new static method
1063 maketrans() on the bytes and bytearray classes. This removes confusion about
1064 the types string.maketrans() is supposed to work with, and mirrors the
1065 methods available on the str class.
1066
R. David Murraydc6da8a2009-04-09 22:16:43 +00001067- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1068 its clarity and its speed.
1069
Matthias Klose091c7b12009-04-07 13:24:27 +00001070- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1071 to avoid compiler warnings.
1072
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001073- Issue #3739: The unicode-internal encoder now reports the number of characters
1074 consumed like any other encoder (instead of the number of bytes).

Guido van Rossum0ad59d42009-03-30 22:01:35 +00001222- Issue #5604: non-ASCII characters in module name passed to
1223 imp.find_module() were converted to UTF-8 while the path is
1224 converted to the default filesystem encoding, causing nonsense.
1225
Benjamin Peterson09832742009-03-26 17:15:46 +00001226- Issue #5126: str.isprintable() returned False for space characters.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00001228- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
1229 the end sys.path, for compatibility with the system install of Python.
1230
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001231- Issue #4688: Add a heuristic so that tuples and dicts containing only
1232 untrackable objects are not tracked by the garbage collector. This can
1233 reduce the size of collections and therefore the garbage collection overhead
1234 on long-running programs, depending on their particular use of datatypes.
1235
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001236- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
1237 improve its performance. Long divisions and remainder operations
1238 are now between 50% and 150% faster.
1239
Mark Dickinsonbd792642009-03-18 20:06:12 +00001240- Issue #4258: Make it possible to use base 2**30 instead of base
1241 2**15 for the internal representation of integers, for performance
1242 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1243 --enable-big-digits option to configure, which overrides the
1244 default. Add sys.int_info structseq to provide information about
1245 the internal format.
1246
Mark Dickinson081dfee2009-03-18 14:47:41 +00001247- Issue #4474: PyUnicode_FromWideChar now converts characters outside
1248 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1249 and sizeof(Py_UNICODE) == 2.
1250
Eric Smith8ec90442009-03-14 12:29:34 +00001251- Issue #5237: Allow auto-numbered fields in str.format(). For
1252 example: '{} {}'.format(1, 2) == '1 2'.
1253
Antoine Pitrou652e7072009-03-13 19:25:20 +00001254- Issue #5392: when a very low recursion limit was set, the interpreter would
1255 abort with a fatal error after the recursion limit was hit twice.
1256
Matthias Klose042f1332009-04-04 14:32:42 +00001257- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
1258 short file names.

1290 bytes already but the failure was non-obvious.
1291
Jesse Noller7af4ef82009-03-30 16:47:15 +00001292- Issue #5177: Multiprocessing's SocketListener class now uses

1303
Lars Gustäbel42e00912009-03-22 20:34:29 +00001304- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1305 forever on incomplete input. That caused tarfile.open() to hang when used
1306 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1307 partial bzip2 compressed data.
1308
Mark Dickinson79f52032009-03-17 23:12:51 +00001309- Issue #2110: Add support for thousands separator and 'n' type

Mark Dickinsonb40b9472009-03-29 16:58:21 +00001328 struct.error instead of returning b'\xff\xff\xff\xff'. The
1329 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants

1349 contained non ascii character on windows.
1350
Benjamin Petersonf5b52242009-03-02 23:31:26 +00001351- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
1352 source has already been decoded into str.
1353
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00001354- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
1355 rotating the object pointer by 4 bits to the right.
1356
Mark Dickinson87ec0852009-02-09 17:15:59 +00001357- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1358 it now forces its argument to double before testing for infinity.
1359
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001360- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1361 returns a non-number type.
1362
Benjamin Peterson87618552009-02-08 15:00:52 +00001363- Issue #5182: Removed memoryview.__str__.

1366 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00001367 the type definition cmpfunc. The tp_compare slot has been renamed
1368 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001369
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001370- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001371 were suppressing all exceptions. These include list() and bytearray().
1372
Mark Dickinson1124e712009-01-28 21:25:58 +00001373- Issue #4707: round(x, n) now returns an integer if x is an integer.
1374 Previously it returned a float.
1375
Antoine Pitroub52ec782009-01-25 16:34:23 +00001376- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1377 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1378 evaluation loop is compiled with a new dispatch mechanism which gives
1379 speedups of up to 20%, depending on the system, on various benchmarks.
1380
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001381- Issue #4874: Most builtin decoders now reject unicode input.

1387
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001388- Issue #4838: When a module is deallocated, free the memory backing the
1389 optional module state data.
1390
Mark Dickinson8055afd2009-01-17 10:04:45 +00001391- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1392 type to (void *).
1393
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001394- Issue #4935: The overflow checking code in the expandtabs() method common
1395 to str, bytes and bytearray could be optimized away by the compiler, letting
1396 the interpreter segfault instead of raising an error.
1397
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001398- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1399 __next__ method.
1400
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001401- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1402 function no longer attempt to call the __long__ slot to convert an object
1403 to an integer. Only the __int__ and __trunc__ slots are examined.
1404

1408
Antoine Pitrouab868312009-01-10 15:40:25 +00001409- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1410 common cases are optimized thanks to a dedicated fast path and a moderate
1411 amount of loop unrolling.
1412
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001413- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1414 collecting the oldest generation) so that allocating lots of objects without
1415 destroying them does not show quadratic performance. Based on a proposal by
1416 Martin von Löwis at
1417 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1418
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001419- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001420 having been closed (for instance, a read() call could return some
1421 previously buffered data). Patch by Dmitry Vasiliev.
1422
Antoine Pitrou05608432009-01-09 18:53:14 +00001423- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1424 flag to work properly. Furthermore, when specifying -u, the text stdout
1425 and stderr streams have line-by-line buffering enabled (the default being
1426 to buffer arbitrary chunks of data).
1427
Raymond Hettinger35631532009-01-09 03:58:09 +00001428- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1429 instead of ints (reducing its size from 4 to 8 times thereby reducing
1430 Python's overall memory).
1431
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001432- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1433 an existing .py counterpart, override the co_filename attributes of all
1434 code objects if the original filename is obsolete (which can happen if the
1435 file has been renamed, moved, or if it is accessed through different paths).
1436 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1437
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001438- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1439 one byte. Also fixes the meaning of len() so that it returns the number of
1440 items, rather than the size in bytes.
1441
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001442- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1443
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001444- Issue #4747: When the terminal does not use utf-8, executing a script with
1445 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1446
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001447- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001448 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001449
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001450- Issue #3680: Reference cycles created through a dict, set or deque iterator
1451 did not get collected.
1452
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001453- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1454 where the tp_hash and tp_dict slots are both NULL.
1455
Georg Brandlccc47b62008-12-28 11:44:14 +00001456- Issue #4759: None is now allowed as the first argument of
1457 bytearray.translate(). It was always allowed for bytes.translate().
1458
Skip Montanaro80072cb2008-12-23 03:51:14 +00001459- Added test case to ensure attempts to read from a file opened for writing
1460 fail.
1461
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001462- Issue #3106: Speedup some comparisons (str/str and int/int).

1465 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1466
Antoine Pitrou621601a2008-12-17 23:18:19 +00001467- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1468 print elapsed times, not only when some objects are uncollectable /
1469 unreachable. Original patch by Neil Schemenauer.
1470
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001471- Issue #3439: Add a bit_length method to int.
1472
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001473- Issue #2173: When getting device encoding, check that return value of
1474 nl_langinfo is not the empty string. This was causing silent build
1475 failures on OS X.
1476
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001477- Issue #4597: Fixed several opcodes that weren't always propagating
1478 exceptions.
1479
1480- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001481 context manager returns a value that cannot be converted to a bool.
1482
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001483- Issue #4445: Replace "sizeof(PyBytesObject)" with
1484 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1485 bytes instances. On a typical machine this saves 3 bytes of memory
1486 (on average) per allocation of a bytes instance.
1487
Christian Heimesa872de52008-12-05 08:26:55 +00001488- Issue #4533: File read operation was dreadfully slow due to a slowly
1489 growing read buffer. Fixed by using the same growth rate algorithm as
1490 Python 2.x.
1491
Antoine Pitrou5504e892008-12-06 21:27:53 +00001492- Issue #4509: Various issues surrounding resize of bytearray objects to
1493 which there are buffer exports (e.g. memoryview instances).
1494
Georg Brandlf9734072008-12-07 15:30:06 +00001495- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1496 method on file objects with closefd=False. The file descriptor is still
1497 kept open but the file object behaves like a closed file. The ``FileIO``
1498 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001499
Antoine Pitroubc420402008-12-07 20:14:49 +00001500- Issue #4569: Interpreter crash when mutating a memoryview with an item size
1501 larger than 1.

Antoine Pitrou88909542009-06-29 13:54:42 +00002112- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
2113 regression tests in parallel, shortening the total runtime.
2114
Guilherme Polo2a998fa2009-06-21 17:40:07 +00002115- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2116 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2117 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2118 skip the tests if DISPLAY is defined but can't be used.
2119
R. David Murraya21e4ca2009-03-31 23:16:50 +00002120- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002121 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002122 from test support, which does the conversion.
2123
Guilherme Polo9de29af2009-01-28 20:40:48 +00002124- Issue #5083: New 'gui' resource for regrtest.
