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.

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.

R. David Murrayba311052009-12-04 00:09:14 +0000638- Issue #7431: use TESTFN in test_linecache instead of trying to create a

650 the road because the internally cached encoders and decoders would point
651 to empty global variables.
652
Antoine Pitrou941ee882009-11-11 20:59:38 +0000653- Issue #7295: Do not use a hardcoded file name in test_tarfile.

667 leak-chasing test runs give sensible results. The previous method of

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000948
949Core and Builtins
950-----------------
951
Mark Dickinson865e01a2009-05-07 16:37:01 +0000952- Issue #5914: Add new C API function PyOS_string_to_double, and
953 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
954
Eric Smith741191f2009-05-06 13:08:15 +0000955- Issue #3382: float.__format__, complex.__format__, and %-formatting
956 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
957 affects nan -> NAN and inf -> INF.
958
Mark Hammond5a607a32009-05-06 08:04:54 +0000959- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
960 in all operations, including splitdrive, split, etc. splitunc() now issues
961 a PendingDeprecation warning.
962
Eric Smith63376222009-05-05 14:04:18 +0000963- Issue #5920: For float.__format__, change the behavior with the
964 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
965 to be like 'g' but with at least one decimal point and with a
966 default precision of 12. Previously, the behavior the same but with
967 a default precision of 6. This more closely matches str(), and
968 reduces surprises when adding alignment flags to the empty
969 presentation type. This also affects the new complex.__format__ in
970 the same way.
971
Martin v. Löwis011e8422009-05-05 04:43:17 +0000972- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
973
R. David Murrayb18500d2009-05-04 22:59:07 +0000974- Issue #5890: in subclasses of 'property' the __doc__ attribute was
975 shadowed by classtype's, even if it was None. property now
976 inserts the __doc__ into the subclass instance __dict__.
977
Antoine Pitrou244651a2009-05-04 18:56:13 +0000978- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
979 sequences. Patch by Nick Barnes and Victor Stinner.
980
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000981- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000982
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000983- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
984 received a new method, detach(). detach() disconnects the underlying stream
985 from the buffer or text IO and returns it.
986
Mark Dickinson33841c32009-05-01 15:37:04 +0000987- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
988 floats with absolute value over 1e50. Also remove length
989 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
990 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000991
Eric Smith741191f2009-05-06 13:08:15 +0000992- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000993 format(complex(1, 2./3), '.5') now produces a sensible result.
994
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000995- Issue #5864: Fix empty format code formatting for floats so that it
996 never gives more than the requested number of significant digits.
997
Eric Smith6dc46f52009-04-27 20:39:49 +0000998- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
999 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1000
Eric Smithcc32a112009-04-26 21:35:14 +00001001- Issue #5835: Deprecate PyOS_ascii_formatd.
1002
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001003- Issue #4971: Fix titlecase for characters that are their own
1004 titlecase, but not their own uppercase.
1005
Benjamin Peterson193152c2009-04-25 01:08:45 +00001006- Issue #5283: Setting __class__ in __del__ caused a segfault.
1007
Mark Dickinsonad476da2009-04-23 19:14:16 +00001008- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1009 z involves nans, infs or negative zeros.
1010
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001011- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001012
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001013- Issue #1869 (and many duplicates): make round(x, n) correctly
1014 rounded for a float x, by using the decimal <-> binary conversions
1015 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1016 consistently agrees with format(x, '.2f').
1017
Benjamin Petersonae937c02009-04-18 20:54:08 +00001018- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1019 some builtin types.
1020
Eric Smith0923d1d2009-04-16 20:16:10 +00001021- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1022
Eric Smith35e84722009-04-16 20:21:28 +00001023- Issue #5515: str.format() type 'n' combined with commas and leading
1024 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001025
1026- Implement PEP 378, Format Specifier for Thousands Separator, for
1027 floats.
1028
Mark Dickinson3370cce2009-04-17 22:40:53 +00001029- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001030 1e11, not 1e12. This avoids printing 13 significant digits in
1031 situations where only 12 of them are correct. Example problem
1032 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1033 long time.)
1034
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001035- Issue #1580: On most platforms, use a 'short' float repr: for a
1036 finite float x, repr(x) now outputs a string based on the shortest
1037 sequence of decimal digits that rounds to x. Previous behaviour was
1038 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001039 Another minor difference is that the new repr switches to
1040 exponential notation at 1e16 instead of the previous 1e17; this
1041 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001042
1043 There's a new sys attribute sys.float_repr_style, which takes
1044 the value 'short' to indicate that we're using short float repr,
1045 and 'legacy' if the short float repr isn't available for one
1046 reason or another.
1047
1048 The float repr change involves incorporating David Gay's 'perfect
1049 rounding' code into the Python core (it's in Python/dtoa.c). As a
1050 secondary consequence, all string-to-float and float-to-string
1051 conversions (including all float formatting operations) will be
1052 correctly rounded on these platforms.
1053
1054 See issue 1580 discussions for details of platforms for which
1055 this change does not apply.
1056
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001057- Issue #5759: float() didn't call __float__ on str subclasses.
1058
Georg Brandlabc38772009-04-12 15:51:51 +00001059- The string.maketrans() function is deprecated; there is a new static method
1060 maketrans() on the bytes and bytearray classes. This removes confusion about
1061 the types string.maketrans() is supposed to work with, and mirrors the
1062 methods available on the str class.
1063
R. David Murraydc6da8a2009-04-09 22:16:43 +00001064- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1065 its clarity and its speed.
1066
Matthias Klose091c7b12009-04-07 13:24:27 +00001067- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1068 to avoid compiler warnings.
1069
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001070- Issue #3739: The unicode-internal encoder now reports the number of characters
1071 consumed like any other encoder (instead of the number of bytes).

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00001225- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
1226 the end sys.path, for compatibility with the system install of Python.
1227
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001228- Issue #4688: Add a heuristic so that tuples and dicts containing only
1229 untrackable objects are not tracked by the garbage collector. This can
1230 reduce the size of collections and therefore the garbage collection overhead
1231 on long-running programs, depending on their particular use of datatypes.
1232
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001233- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
1234 improve its performance. Long divisions and remainder operations
1235 are now between 50% and 150% faster.
1236
Mark Dickinsonbd792642009-03-18 20:06:12 +00001237- Issue #4258: Make it possible to use base 2**30 instead of base
1238 2**15 for the internal representation of integers, for performance
1239 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1240 --enable-big-digits option to configure, which overrides the
1241 default. Add sys.int_info structseq to provide information about
1242 the internal format.
1243
Mark Dickinson081dfee2009-03-18 14:47:41 +00001244- Issue #4474: PyUnicode_FromWideChar now converts characters outside
1245 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1246 and sizeof(Py_UNICODE) == 2.
1247
Eric Smith8ec90442009-03-14 12:29:34 +00001248- Issue #5237: Allow auto-numbered fields in str.format(). For
1249 example: '{} {}'.format(1, 2) == '1 2'.
1250
Antoine Pitrou652e7072009-03-13 19:25:20 +00001251- Issue #5392: when a very low recursion limit was set, the interpreter would
1252 abort with a fatal error after the recursion limit was hit twice.
1253
Matthias Klose042f1332009-04-04 14:32:42 +00001254- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

1300
Lars Gustäbel42e00912009-03-22 20:34:29 +00001301- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1302 forever on incomplete input. That caused tarfile.open() to hang when used
1303 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1304 partial bzip2 compressed data.

Mark Dickinsonb40b9472009-03-29 16:58:21 +00001325 struct.error instead of returning b'\xff\xff\xff\xff'. The
1326 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants

Antoine Pitrou79eee6b2009-02-13 14:01:05 +00001351- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
1352 rotating the object pointer by 4 bits to the right.
1353
Mark Dickinson87ec0852009-02-09 17:15:59 +00001354- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1355 it now forces its argument to double before testing for infinity.
1356
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001357- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1358 returns a non-number type.
1359
Benjamin Peterson87618552009-02-08 15:00:52 +00001360- Issue #5182: Removed memoryview.__str__.

Mark Dickinsone94c6792009-02-02 20:36:42 +00001364 the type definition cmpfunc. The tp_compare slot has been renamed
1365 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001366
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001367- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001368 were suppressing all exceptions. These include list() and bytearray().
1369
Mark Dickinson1124e712009-01-28 21:25:58 +00001370- Issue #4707: round(x, n) now returns an integer if x is an integer.
1371 Previously it returned a float.
1372
Antoine Pitroub52ec782009-01-25 16:34:23 +00001373- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1374 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1375 evaluation loop is compiled with a new dispatch mechanism which gives
1376 speedups of up to 20%, depending on the system, on various benchmarks.
1377
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001378- Issue #4874: Most builtin decoders now reject unicode input.

1384
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001385- Issue #4838: When a module is deallocated, free the memory backing the
1386 optional module state data.
1387
Mark Dickinson8055afd2009-01-17 10:04:45 +00001388- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1389 type to (void *).
1390
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001391- Issue #4935: The overflow checking code in the expandtabs() method common
1392 to str, bytes and bytearray could be optimized away by the compiler, letting
1393 the interpreter segfault instead of raising an error.
1394
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001395- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1396 __next__ method.
1397
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001398- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1399 function no longer attempt to call the __long__ slot to convert an object

1405
Antoine Pitrouab868312009-01-10 15:40:25 +00001406- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1407 common cases are optimized thanks to a dedicated fast path and a moderate
1408 amount of loop unrolling.
1409
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001410- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1411 collecting the oldest generation) so that allocating lots of objects without
1412 destroying them does not show quadratic performance. Based on a proposal by
1413 Martin von Löwis at
1414 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1415
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001416- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001417 having been closed (for instance, a read() call could return some
1418 previously buffered data). Patch by Dmitry Vasiliev.
1419
Antoine Pitrou05608432009-01-09 18:53:14 +00001420- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1421 flag to work properly. Furthermore, when specifying -u, the text stdout
1422 and stderr streams have line-by-line buffering enabled (the default being
1423 to buffer arbitrary chunks of data).
1424
Raymond Hettinger35631532009-01-09 03:58:09 +00001425- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1426 instead of ints (reducing its size from 4 to 8 times thereby reducing
1427 Python's overall memory).
1428
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001429- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1430 an existing .py counterpart, override the co_filename attributes of all
1431 code objects if the original filename is obsolete (which can happen if the
1432 file has been renamed, moved, or if it is accessed through different paths).
1433 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1434
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001435- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1436 one byte. Also fixes the meaning of len() so that it returns the number of
1437 items, rather than the size in bytes.
1438
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001439- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1440
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001441- Issue #4747: When the terminal does not use utf-8, executing a script with
1442 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1443
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001444- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001445 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001446
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001447- Issue #3680: Reference cycles created through a dict, set or deque iterator
1448 did not get collected.
1449
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001450- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1451 where the tp_hash and tp_dict slots are both NULL.
1452
Georg Brandlccc47b62008-12-28 11:44:14 +00001453- Issue #4759: None is now allowed as the first argument of
1454 bytearray.translate(). It was always allowed for bytes.translate().
1455
Skip Montanaro80072cb2008-12-23 03:51:14 +00001456- Added test case to ensure attempts to read from a file opened for writing
1457 fail.
1458
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001459- Issue #3106: Speedup some comparisons (str/str and int/int).

1462 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1463
Antoine Pitrou621601a2008-12-17 23:18:19 +00001464- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1465 print elapsed times, not only when some objects are uncollectable /
1466 unreachable. Original patch by Neil Schemenauer.
1467
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001468- Issue #3439: Add a bit_length method to int.
1469
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001470- Issue #2173: When getting device encoding, check that return value of
1471 nl_langinfo is not the empty string. This was causing silent build
1472 failures on OS X.
1473
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001474- Issue #4597: Fixed several opcodes that weren't always propagating
1475 exceptions.
1476
1477- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001478 context manager returns a value that cannot be converted to a bool.
1479
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001480- Issue #4445: Replace "sizeof(PyBytesObject)" with
1481 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1482 bytes instances. On a typical machine this saves 3 bytes of memory
1483 (on average) per allocation of a bytes instance.
1484
Christian Heimesa872de52008-12-05 08:26:55 +00001485- Issue #4533: File read operation was dreadfully slow due to a slowly
1486 growing read buffer. Fixed by using the same growth rate algorithm as
1487 Python 2.x.
1488
Antoine Pitrou5504e892008-12-06 21:27:53 +00001489- Issue #4509: Various issues surrounding resize of bytearray objects to
1490 which there are buffer exports (e.g. memoryview instances).
1491
Georg Brandlf9734072008-12-07 15:30:06 +00001492- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1493 method on file objects with closefd=False. The file descriptor is still
1494 kept open but the file object behaves like a closed file. The ``FileIO``
1495 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001496
Antoine Pitroubc420402008-12-07 20:14:49 +00001497- Issue #4569: Interpreter crash when mutating a memoryview with an item size
1498 larger than 1.

Antoine Pitrou88909542009-06-29 13:54:42 +00002109- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
2110 regression tests in parallel, shortening the total runtime.
2111
Guilherme Polo2a998fa2009-06-21 17:40:07 +00002112- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2113 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2114 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2115 skip the tests if DISPLAY is defined but can't be used.
2116
R. David Murraya21e4ca2009-03-31 23:16:50 +00002117- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002118 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002119 from test support, which does the conversion.
2120
Guilherme Polo9de29af2009-01-28 20:40:48 +00002121- Issue #5083: New 'gui' resource for regrtest.
