12Core and Builtins
13-----------------
14
Larry Hastings1373a072010-02-24 22:49:58 +000015- Issue #5939: Add additional runtime checking to ensure a valid capsule
16 in Modules/_ctypes/callproc.c.
17
Eric Smith0facd772010-02-24 15:42:29 +000018- Issue #7309: Fix unchecked attribute access when converting
19 UnicodeEncodeError, UnicodeDecodeError, and UnicodeTranslateError to
20 strings.
21
Eric Smithabb28c62010-02-23 00:22:24 +000022- Issue #6902: Fix problem with built-in types format incorrectly with
23 0 padding.
24
Eric Smith4e260c52010-02-22 18:54:44 +000025- Issue #7988: Fix default alignment to be right aligned for
26 complex.__format__. Now it matches other numeric types.
27
Eric Smith68af50b2010-02-22 14:58:30 +000028- Issue #5988: Remove deprecated functions PyOS_ascii_formatd,
29 PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string
30 and PyOS_string_to_double instead. See issue #5835 for the original
31 deprecations.
32
Antoine Pitrou05b7c562010-02-02 22:47:00 +000033- Issue #7385: Fix a crash in `MemoryView_FromObject` when
34 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
35
Mark Dickinsonbc099642010-01-29 17:27:24 +000036- Issue #7788: Fix an interpreter crash produced by deleting a list
37 slice with very large step value.
38
Eric Smithf7bb5782010-01-27 00:44:57 +000039- Issue #7766: Change sys.getwindowsversion() return value to a named
40 tuple and add the additional members returned in an OSVERSIONINFOEX
41 structure. The new members are service_pack_major, service_pack_minor,
42 suite_mask, and product_type.
43
Antoine Pitroufc8d6f42010-01-17 12:38:54 +000044- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
45 could crash in many places because of the PyByteArray_AS_STRING() macro
46 returning NULL. The macro now returns a statically allocated empty
47 string instead.
48
Antoine Pitroub7fbcd32010-01-16 18:37:38 +000049- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
50 where the right hand operand is a set of constants, by turning the set into
51 a frozenset and pre-building it as a constant. The comparison operation
52 is made against the constant instead of building a new set each time it is
53 executed (a similar optimization already existed which turned a list of
54 constants into a pre-built tuple). Patch and additional tests by Dave
55 Malcolm.
56
Antoine Pitrouf2c54842010-01-13 08:07:53 +000057- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
58 methods of bytes, bytearray and unicode objects by using a common
59 implementation based on stringlib's fast search. Patch by Florent Xicluna.
60
Mark Dickinson45b63652010-01-16 18:10:25 +000061- Issue #7632: Fix various str -> float conversion bugs present in 2.7
62 alpha 2, including: (1) a serious 'wrong output' bug that could
63 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
64 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +000065 strings corresponding to subnormal values, (3) a memory leak for
66 some values large enough to cause overflow, and (4) a number of
67 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +000068
Benjamin Petersonaea44282010-01-04 01:10:28 +000069- The __complex__ method is now looked up on the class of instances to make it
70 consistent with other special methods.
71

73 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
74
Benjamin Petersond12362a2009-12-30 19:44:54 +000075- Issue #7604: Deleting an unset slotted attribute did not raise an
76 AttributeError.
77
Mark Dickinson9ab44b52009-12-30 16:22:49 +000078- Issue #7534: Fix handling of IEEE specials (infinities, nans,
79 negative zero) in ** operator. The behaviour now conforms to that
80 described in C99 Annex F.
81
Mark Dickinsoncbb62742009-12-27 15:09:50 +000082- Issue #1811: improve accuracy and cross-platform consistency for
83 true division of integers: the result of a/b is now correctly
84 rounded for ints a and b (at least on IEEE 754 platforms), and in
85 particular does not depend on the internal representation of an int.
86
Ronald Oussoren6f6c5622009-12-24 14:03:19 +000087- Issue #6834: replace the implementation for the 'python' and 'pythonw'
88 executables on OSX.
89
90 These executables now work properly with the arch(1) command:
91 ``arch -ppc python`` will start a universal binary version of python
92 in PPC mode (unlike previous releases).
93
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +000094- Issue #7466: segmentation fault when the garbage collector is called
95 in the middle of populating a tuple. Patch by Florent Xicluna.
96

104 on MacOSX 10.6.
105
Philip Jenvey1309adb2009-11-17 03:43:14 +0000106- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
107
Mark Dickinson6f1d0492009-11-15 13:58:49 +0000108- Issue #6970: Remove redundant calls when comparing objects that don't
109 implement the relevant rich comparison methods.
110
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000111- Issue #7298: fixes for range and reversed(range(...)). Iteration
112 over range(a, b, c) incorrectly gave an empty iterator when a, b and
113 c fit in C long but the length of the range did not. Also fix
114 several cases where reversed(range(a, b, c)) gave wrong results, and
115 fix a refleak for reversed(range(a, b, c)) with large arguments.
116
Raymond Hettingerfc438512009-11-01 20:55:33 +0000117- Issue #7244: itertools.izip_longest() no longer ignores exceptions

126
Antoine Pitroub6ef9632009-10-24 20:47:05 +0000127- Support for AtheOS has been completely removed from the code base. It was
128 disabled since Python 3.0.
129
130- Support for several legacy threading libraries has been disabled. These
131 libraries are: Mach C threads, SunOS LWP, GNU pth, Irix threads. Support code
132 will be entirely removed in 3.3.

Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000316- Issue #6939: Fix file I/O objects in the `io` module to keep the original
317 file position when calling `truncate()`. It would previously change the
318 file position to the given argument, which goes against the tradition of
319 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
320
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000321- Issue #7610: Reworked implementation of the internal
322 :class:`zipfile.ZipExtFile` class used to represent files stored inside
323 an archive. The new implementation is significantly faster and can
324 be wrapped in a :class:`io.BufferedReader` object for more speedups.
325 It also solves an issue where interleaved calls to `read()` and
326 `readline()` give wrong results. Patch by Nir Aides.
327
Jesse Noller1f0b6582010-01-27 03:36:01 +0000328- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,

488
Nick Coghlan260bd3e2009-11-16 06:49:25 +0000489- Issue #6816: runpy now provides a run_path function that allows Python code
490 to execute file paths that refer to source or compiled Python files as well
491 as zipfiles, directories and other valid sys.path entries that contain a
492 __main__.py file. This allows applications that run other Python scripts to
493 support the same flexibility as the CPython command line itself.
494
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000495- Issue #7318: multiprocessing now uses a timeout when it fails to establish

531 failures on systems with slightly bogus mtime behaviour.
532
Gregory P. Smith50467882009-11-01 18:42:17 +0000533- Issue #7246 & Issue #7208: getpass now properly flushes input before
534 reading from stdin so that existing input does not confuse it and

822
R. David Murrayba311052009-12-04 00:09:14 +0000823- Issue #7431: use TESTFN in test_linecache instead of trying to create a

826
R. David Murray35768ad2009-11-15 00:23:21 +0000827- Issue #7324: add a sanity check to regrtest argument parsing to

831 a test fails. Can be combined with -j.
832
Antoine Pitrou060cee22009-11-13 16:29:04 +0000833- Issue #6551: test_zipimport could import and then destroy some modules of
834 the encodings package, which would make other tests fail further down
835 the road because the internally cached encoders and decoders would point
836 to empty global variables.
837
Antoine Pitrou941ee882009-11-11 20:59:38 +0000838- Issue #7295: Do not use a hardcoded file name in test_tarfile.

852 leak-chasing test runs give sensible results. The previous method of
853 reaping threads could return successfully while some Thread objects were
854 still referenced. This also introduces a new private function:
855 :func:`_thread._count()`.
856
R. David Murray27144602009-10-19 15:26:16 +0000857- Issue #7151: fixed regrtest -j so that output to stderr from a test no
858 longer runs the risk of causing the worker thread to fail.
859
Antoine Pitrou4de39cd2009-10-10 21:08:31 +0000860- Issue #7055: test___all__ now greedily detects all modules which have an
861 __all__ attribute, rather than using a hardcoded and incomplete list.
862

1063 than an int, which makes some operations possible under 64-bit Linux (e.g.

Mark Dickinson865e01a2009-05-07 16:37:01 +00001144- Issue #5914: Add new C API function PyOS_string_to_double, and
1145 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1146
Eric Smith741191f2009-05-06 13:08:15 +00001147- Issue #3382: float.__format__, complex.__format__, and %-formatting
1148 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1149 affects nan -> NAN and inf -> INF.
1150
Mark Hammond5a607a32009-05-06 08:04:54 +00001151- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1152 in all operations, including splitdrive, split, etc. splitunc() now issues

Eric Smith63376222009-05-05 14:04:18 +00001155- Issue #5920: For float.__format__, change the behavior with the
1156 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1157 to be like 'g' but with at least one decimal point and with a
1158 default precision of 12. Previously, the behavior the same but with
1159 a default precision of 6. This more closely matches str(), and
1160 reduces surprises when adding alignment flags to the empty
1161 presentation type. This also affects the new complex.__format__ in
1162 the same way.
1163
Martin v. Löwis011e8422009-05-05 04:43:17 +00001164- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00001175- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1176 received a new method, detach(). detach() disconnects the underlying stream
1177 from the buffer or text IO and returns it.
1178
Mark Dickinson33841c32009-05-01 15:37:04 +00001179- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1180 floats with absolute value over 1e50. Also remove length
1181 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %

1188 never gives more than the requested number of significant digits.

1201 z involves nans, infs or negative zeros.

Mark Dickinsone6a076d2009-04-18 11:48:33 +00001205- Issue #1869 (and many duplicates): make round(x, n) correctly
1206 rounded for a float x, by using the decimal <-> binary conversions
1207 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1208 consistently agrees with format(x, '.2f').
1209
Benjamin Petersonae937c02009-04-18 20:54:08 +00001210- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

Eric Smith35e84722009-04-16 20:21:28 +00001215- Issue #5515: str.format() type 'n' combined with commas and leading
1216 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001217
1218- Implement PEP 378, Format Specifier for Thousands Separator, for
1219 floats.
1220
Mark Dickinson3370cce2009-04-17 22:40:53 +00001221- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001222 1e11, not 1e12. This avoids printing 13 significant digits in
1223 situations where only 12 of them are correct. Example problem
1224 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1225 long time.)
1226
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001227- Issue #1580: On most platforms, use a 'short' float repr: for a
1228 finite float x, repr(x) now outputs a string based on the shortest
1229 sequence of decimal digits that rounds to x. Previous behaviour was
1230 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001231 Another minor difference is that the new repr switches to
1232 exponential notation at 1e16 instead of the previous 1e17; this
1233 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001234
1235 There's a new sys attribute sys.float_repr_style, which takes
1236 the value 'short' to indicate that we're using short float repr,
1237 and 'legacy' if the short float repr isn't available for one
1238 reason or another.
1239
1240 The float repr change involves incorporating David Gay's 'perfect
1241 rounding' code into the Python core (it's in Python/dtoa.c). As a
1242 secondary consequence, all string-to-float and float-to-string
1243 conversions (including all float formatting operations) will be
1244 correctly rounded on these platforms.
1245
1246 See issue 1580 discussions for details of platforms for which
1247 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001249- Issue #5759: float() didn't call __float__ on str subclasses.
1250
Georg Brandlabc38772009-04-12 15:51:51 +00001251- The string.maketrans() function is deprecated; there is a new static method
1252 maketrans() on the bytes and bytearray classes. This removes confusion about
1253 the types string.maketrans() is supposed to work with, and mirrors the
1254 methods available on the str class.

1518 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
1519 have been removed from the struct module.

1544 rotating the object pointer by 4 bits to the right.
1545
Mark Dickinson87ec0852009-02-09 17:15:59 +00001546- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1547 it now forces its argument to double before testing for infinity.
1548
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001549- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001558
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001559- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001560 were suppressing all exceptions. These include list() and bytearray().

1564
Antoine Pitroub52ec782009-01-25 16:34:23 +00001565- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1566 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1567 evaluation loop is compiled with a new dispatch mechanism which gives
1568 speedups of up to 20%, depending on the system, on various benchmarks.
1569
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001570- Issue #4874: Most builtin decoders now reject unicode input.

1576
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001577- Issue #4838: When a module is deallocated, free the memory backing the
1578 optional module state data.
1579
Mark Dickinson8055afd2009-01-17 10:04:45 +00001580- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1581 type to (void *).
1582
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001583- Issue #4935: The overflow checking code in the expandtabs() method common
1584 to str, bytes and bytearray could be optimized away by the compiler, letting
1585 the interpreter segfault instead of raising an error.
1586
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001587- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1588 __next__ method.
1589
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001590- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1591 function no longer attempt to call the __long__ slot to convert an object
1592 to an integer. Only the __int__ and __trunc__ slots are examined.
1593
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001594- Issue #4893: Use NT threading on CE.
1595
Martin v. Löwisec59d042009-01-12 07:59:10 +00001596- Issue #4915: Port sysmodule to Windows CE.
1597
Antoine Pitrouab868312009-01-10 15:40:25 +00001598- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1599 common cases are optimized thanks to a dedicated fast path and a moderate
1600 amount of loop unrolling.
1601
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001602- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1603 collecting the oldest generation) so that allocating lots of objects without
1604 destroying them does not show quadratic performance. Based on a proposal by
1605 Martin von Löwis at
1606 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1607
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001608- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001609 having been closed (for instance, a read() call could return some
1610 previously buffered data). Patch by Dmitry Vasiliev.
1611
Antoine Pitrou05608432009-01-09 18:53:14 +00001612- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1613 flag to work properly. Furthermore, when specifying -u, the text stdout
1614 and stderr streams have line-by-line buffering enabled (the default being
1615 to buffer arbitrary chunks of data).
1616
Raymond Hettinger35631532009-01-09 03:58:09 +00001617- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1618 instead of ints (reducing its size from 4 to 8 times thereby reducing
1619 Python's overall memory).
1620
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001621- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1622 an existing .py counterpart, override the co_filename attributes of all
1623 code objects if the original filename is obsolete (which can happen if the
1624 file has been renamed, moved, or if it is accessed through different paths).
1625 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1626
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001627- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1628 one byte. Also fixes the meaning of len() so that it returns the number of
1629 items, rather than the size in bytes.
1630
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001631- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1632
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001633- Issue #4747: When the terminal does not use utf-8, executing a script with
1634 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1635
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001636- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001637 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001638
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001639- Issue #3680: Reference cycles created through a dict, set or deque iterator
1640 did not get collected.
1641
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001642- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1643 where the tp_hash and tp_dict slots are both NULL.
1644
Georg Brandlccc47b62008-12-28 11:44:14 +00001645- Issue #4759: None is now allowed as the first argument of
1646 bytearray.translate(). It was always allowed for bytes.translate().
1647
Skip Montanaro80072cb2008-12-23 03:51:14 +00001648- Added test case to ensure attempts to read from a file opened for writing
1649 fail.
1650
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001651- Issue #3106: Speedup some comparisons (str/str and int/int).

1655
Antoine Pitrou621601a2008-12-17 23:18:19 +00001656- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1657 print elapsed times, not only when some objects are uncollectable /
1658 unreachable. Original patch by Neil Schemenauer.
1659
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001660- Issue #3439: Add a bit_length method to int.
1661
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001662- Issue #2173: When getting device encoding, check that return value of
1663 nl_langinfo is not the empty string. This was causing silent build
1664 failures on OS X.
1665
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001666- Issue #4597: Fixed several opcodes that weren't always propagating
1667 exceptions.
1668
1669- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001670 context manager returns a value that cannot be converted to a bool.
1671
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001672- Issue #4445: Replace "sizeof(PyBytesObject)" with
1673 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1674 bytes instances. On a typical machine this saves 3 bytes of memory
1675 (on average) per allocation of a bytes instance.
1676
Christian Heimesa872de52008-12-05 08:26:55 +00001677- Issue #4533: File read operation was dreadfully slow due to a slowly
1678 growing read buffer. Fixed by using the same growth rate algorithm as
1679 Python 2.x.
1680
Antoine Pitrou5504e892008-12-06 21:27:53 +00001681- Issue #4509: Various issues surrounding resize of bytearray objects to
1682 which there are buffer exports (e.g. memoryview instances).
1683
Georg Brandlf9734072008-12-07 15:30:06 +00001684- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1685 method on file objects with closefd=False. The file descriptor is still
1686 kept open but the file object behaves like a closed file. The ``FileIO``
1687 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001688
Antoine Pitroubc420402008-12-07 20:14:49 +00001689- Issue #4569: Interpreter crash when mutating a memoryview with an item size
1690 larger than 1.

1695
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001696- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1697 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1698 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1699 of using the replace error handler in PyUnicode_DecodeUTF8().
