16 a fatal error in low memory condition.
17
Victor Stinner6aa278e2010-03-03 00:18:49 +000018- Issue #7820: The parser tokenizer restores all bytes in the right if
19 the BOM check fails.
20
Benjamin Peterson23e018a2010-02-27 17:40:01 +000021- Handle errors from looking up __prepare__ correctly.
22

24 in Modules/_ctypes/callproc.c.
25
Eric Smith0facd772010-02-24 15:42:29 +000026- Issue #7309: Fix unchecked attribute access when converting
27 UnicodeEncodeError, UnicodeDecodeError, and UnicodeTranslateError to
28 strings.
29
Eric Smithabb28c62010-02-23 00:22:24 +000030- Issue #6902: Fix problem with built-in types format incorrectly with
31 0 padding.
32
Eric Smith4e260c52010-02-22 18:54:44 +000033- Issue #7988: Fix default alignment to be right aligned for
34 complex.__format__. Now it matches other numeric types.
35
Eric Smith68af50b2010-02-22 14:58:30 +000036- Issue #5988: Remove deprecated functions PyOS_ascii_formatd,
37 PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string
38 and PyOS_string_to_double instead. See issue #5835 for the original
39 deprecations.
40
Antoine Pitrou05b7c562010-02-02 22:47:00 +000041- Issue #7385: Fix a crash in `MemoryView_FromObject` when
42 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
43
Mark Dickinsonbc099642010-01-29 17:27:24 +000044- Issue #7788: Fix an interpreter crash produced by deleting a list
45 slice with very large step value.
46
Eric Smithf7bb5782010-01-27 00:44:57 +000047- Issue #7766: Change sys.getwindowsversion() return value to a named
48 tuple and add the additional members returned in an OSVERSIONINFOEX
49 structure. The new members are service_pack_major, service_pack_minor,
50 suite_mask, and product_type.
51
Antoine Pitroufc8d6f42010-01-17 12:38:54 +000052- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
53 could crash in many places because of the PyByteArray_AS_STRING() macro
54 returning NULL. The macro now returns a statically allocated empty
55 string instead.
56
Antoine Pitroub7fbcd32010-01-16 18:37:38 +000057- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
58 where the right hand operand is a set of constants, by turning the set into
59 a frozenset and pre-building it as a constant. The comparison operation
60 is made against the constant instead of building a new set each time it is
61 executed (a similar optimization already existed which turned a list of
62 constants into a pre-built tuple). Patch and additional tests by Dave
63 Malcolm.
64
Antoine Pitrouf2c54842010-01-13 08:07:53 +000065- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
66 methods of bytes, bytearray and unicode objects by using a common
67 implementation based on stringlib's fast search. Patch by Florent Xicluna.
68
Mark Dickinson45b63652010-01-16 18:10:25 +000069- Issue #7632: Fix various str -> float conversion bugs present in 2.7
70 alpha 2, including: (1) a serious 'wrong output' bug that could
71 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
72 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +000073 strings corresponding to subnormal values, (3) a memory leak for
74 some values large enough to cause overflow, and (4) a number of
75 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +000076
Benjamin Petersonaea44282010-01-04 01:10:28 +000077- The __complex__ method is now looked up on the class of instances to make it
78 consistent with other special methods.

81 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
82
Benjamin Petersond12362a2009-12-30 19:44:54 +000083- Issue #7604: Deleting an unset slotted attribute did not raise an
84 AttributeError.
85
Mark Dickinson9ab44b52009-12-30 16:22:49 +000086- Issue #7534: Fix handling of IEEE specials (infinities, nans,
87 negative zero) in ** operator. The behaviour now conforms to that
88 described in C99 Annex F.
89
Mark Dickinsoncbb62742009-12-27 15:09:50 +000090- Issue #1811: improve accuracy and cross-platform consistency for
91 true division of integers: the result of a/b is now correctly
92 rounded for ints a and b (at least on IEEE 754 platforms), and in
93 particular does not depend on the internal representation of an int.
94
Ronald Oussoren6f6c5622009-12-24 14:03:19 +000095- Issue #6834: replace the implementation for the 'python' and 'pythonw'
96 executables on OSX.
97
98 These executables now work properly with the arch(1) command:
99 ``arch -ppc python`` will start a universal binary version of python
100 in PPC mode (unlike previous releases).
101
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000102- Issue #7466: segmentation fault when the garbage collector is called

106 with invalid values.
107
Amaury Forgeot d'Arc7d0bddd2009-11-30 00:08:56 +0000108- Issue #6077: On Windows, files opened with tempfile.TemporaryFile in "wt+"
109 mode would appear truncated on the first '0x1a' byte (aka. Ctrl+Z).

Mark Dickinson6f1d0492009-11-15 13:58:49 +0000116- Issue #6970: Remove redundant calls when comparing objects that don't
117 implement the relevant rich comparison methods.
118
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000119- Issue #7298: fixes for range and reversed(range(...)). Iteration
120 over range(a, b, c) incorrectly gave an empty iterator when a, b and
121 c fit in C long but the length of the range did not. Also fix
122 several cases where reversed(range(a, b, c)) gave wrong results, and
123 fix a refleak for reversed(range(a, b, c)) with large arguments.
124
Raymond Hettingerfc438512009-11-01 20:55:33 +0000125- Issue #7244: itertools.izip_longest() no longer ignores exceptions

316 interpreter shutdown.
317
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000318- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
319 in XML processing instructions and comments. These raw characters are
320 allowed by the XML specification, and are necessary when outputting e.g.
321 PHP code in a processing instruction. Patch by Neil Muller.
322
Antoine Pitrouc77dd322010-02-09 16:51:16 +0000323- Issue #6233: ElementTree failed converting unicode characters to XML

334
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000335- Issue #6939: Fix file I/O objects in the `io` module to keep the original
336 file position when calling `truncate()`. It would previously change the
337 file position to the given argument, which goes against the tradition of
338 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
339
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000340- Issue #7610: Reworked implementation of the internal
341 :class:`zipfile.ZipExtFile` class used to represent files stored inside
342 an archive. The new implementation is significantly faster and can
343 be wrapped in a :class:`io.BufferedReader` object for more speedups.
344 It also solves an issue where interleaved calls to `read()` and
345 `readline()` give wrong results. Patch by Nir Aides.
346
Jesse Noller1f0b6582010-01-27 03:36:01 +0000347- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,

507
Nick Coghlan260bd3e2009-11-16 06:49:25 +0000508- Issue #6816: runpy now provides a run_path function that allows Python code
509 to execute file paths that refer to source or compiled Python files as well
510 as zipfiles, directories and other valid sys.path entries that contain a
511 __main__.py file. This allows applications that run other Python scripts to
512 support the same flexibility as the CPython command line itself.
513
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000514- Issue #7318: multiprocessing now uses a timeout when it fails to establish

550 failures on systems with slightly bogus mtime behaviour.
551
Gregory P. Smith50467882009-11-01 18:42:17 +0000552- Issue #7246 & Issue #7208: getpass now properly flushes input before
553 reading from stdin so that existing input does not confuse it and

838
R. David Murray378c0cf2010-02-24 01:46:21 +0000839- Issue #6292: for the moment at least, the test suite runs cleanly if python

853
R. David Murray445448c2009-12-20 17:28:31 +0000854- Issue #7376: instead of running a self-test (which was failing) when called

864 user running the tests.
865
R. David Murray35768ad2009-11-15 00:23:21 +0000866- Issue #7324: add a sanity check to regrtest argument parsing to

871
Antoine Pitrou060cee22009-11-13 16:29:04 +0000872- Issue #6551: test_zipimport could import and then destroy some modules of
873 the encodings package, which would make other tests fail further down
874 the road because the internally cached encoders and decoders would point
875 to empty global variables.
876
Antoine Pitrou941ee882009-11-11 20:59:38 +0000877- Issue #7295: Do not use a hardcoded file name in test_tarfile.

891 leak-chasing test runs give sensible results. The previous method of
892 reaping threads could return successfully while some Thread objects were
893 still referenced. This also introduces a new private function:
894 :func:`_thread._count()`.
895
R. David Murray27144602009-10-19 15:26:16 +0000896- Issue #7151: fixed regrtest -j so that output to stderr from a test no

1184 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1185
Eric Smith741191f2009-05-06 13:08:15 +00001186- Issue #3382: float.__format__, complex.__format__, and %-formatting
1187 no longer map 'F' to 'f'. Because of issue #5859 (below), this only

Eric Smith63376222009-05-05 14:04:18 +00001194- Issue #5920: For float.__format__, change the behavior with the
1195 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1196 to be like 'g' but with at least one decimal point and with a
1197 default precision of 12. Previously, the behavior the same but with
1198 a default precision of 6. This more closely matches str(), and
1199 reduces surprises when adding alignment flags to the empty
1200 presentation type. This also affects the new complex.__format__ in
1201 the same way.

1215 received a new method, detach(). detach() disconnects the underlying stream
1216 from the buffer or text IO and returns it.
1217
Mark Dickinson33841c32009-05-01 15:37:04 +00001218- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1219 floats with absolute value over 1e50. Also remove length
1220 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1221 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +00001223- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001224 format(complex(1, 2./3), '.5') now produces a sensible result.
1225
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001226- Issue #5864: Fix empty format code formatting for floats so that it
1227 never gives more than the requested number of significant digits.

1241
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001242- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001243
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001244- Issue #1869 (and many duplicates): make round(x, n) correctly
1245 rounded for a float x, by using the decimal <-> binary conversions
1246 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1247 consistently agrees with format(x, '.2f').
1248
Benjamin Petersonae937c02009-04-18 20:54:08 +00001249- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

1251
Eric Smith0923d1d2009-04-16 20:16:10 +00001252- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1253
Eric Smith35e84722009-04-16 20:21:28 +00001254- Issue #5515: str.format() type 'n' combined with commas and leading
1255 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001256
1257- Implement PEP 378, Format Specifier for Thousands Separator, for
1258 floats.
1259
Mark Dickinson3370cce2009-04-17 22:40:53 +00001260- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001261 1e11, not 1e12. This avoids printing 13 significant digits in
1262 situations where only 12 of them are correct. Example problem
1263 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1264 long time.)
1265
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001266- Issue #1580: On most platforms, use a 'short' float repr: for a
1267 finite float x, repr(x) now outputs a string based on the shortest
1268 sequence of decimal digits that rounds to x. Previous behaviour was
1269 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001270 Another minor difference is that the new repr switches to
1271 exponential notation at 1e16 instead of the previous 1e17; this
1272 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001273
1274 There's a new sys attribute sys.float_repr_style, which takes
1275 the value 'short' to indicate that we're using short float repr,
1276 and 'legacy' if the short float repr isn't available for one
1277 reason or another.
1278
1279 The float repr change involves incorporating David Gay's 'perfect
1280 rounding' code into the Python core (it's in Python/dtoa.c). As a
1281 secondary consequence, all string-to-float and float-to-string
1282 conversions (including all float formatting operations) will be
1283 correctly rounded on these platforms.
1284
1285 See issue 1580 discussions for details of platforms for which
1286 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001288- Issue #5759: float() didn't call __float__ on str subclasses.
1289
Georg Brandlabc38772009-04-12 15:51:51 +00001290- The string.maketrans() function is deprecated; there is a new static method
1291 maketrans() on the bytes and bytearray classes. This removes confusion about
1292 the types string.maketrans() is supposed to work with, and mirrors the
1293 methods available on the str class.

1460 untrackable objects are not tracked by the garbage collector. This can
1461 reduce the size of collections and therefore the garbage collection overhead
1462 on long-running programs, depending on their particular use of datatypes.

1583 rotating the object pointer by 4 bits to the right.
1584
Mark Dickinson87ec0852009-02-09 17:15:59 +00001585- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1586 it now forces its argument to double before testing for infinity.
1587
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001588- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001597
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001598- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001599 were suppressing all exceptions. These include list() and bytearray().
1600
Mark Dickinson1124e712009-01-28 21:25:58 +00001601- Issue #4707: round(x, n) now returns an integer if x is an integer.
1602 Previously it returned a float.
1603
Antoine Pitroub52ec782009-01-25 16:34:23 +00001604- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1605 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1606 evaluation loop is compiled with a new dispatch mechanism which gives
1607 speedups of up to 20%, depending on the system, on various benchmarks.
1608
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001609- Issue #4874: Most builtin decoders now reject unicode input.

1615
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001616- Issue #4838: When a module is deallocated, free the memory backing the
1617 optional module state data.
1618
Mark Dickinson8055afd2009-01-17 10:04:45 +00001619- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1620 type to (void *).
1621
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001622- Issue #4935: The overflow checking code in the expandtabs() method common
1623 to str, bytes and bytearray could be optimized away by the compiler, letting
1624 the interpreter segfault instead of raising an error.
1625
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001626- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1627 __next__ method.
1628
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001629- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1630 function no longer attempt to call the __long__ slot to convert an object
1631 to an integer. Only the __int__ and __trunc__ slots are examined.
1632
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001633- Issue #4893: Use NT threading on CE.
1634
Martin v. Löwisec59d042009-01-12 07:59:10 +00001635- Issue #4915: Port sysmodule to Windows CE.
1636
Antoine Pitrouab868312009-01-10 15:40:25 +00001637- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1638 common cases are optimized thanks to a dedicated fast path and a moderate
1639 amount of loop unrolling.
1640
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001641- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1642 collecting the oldest generation) so that allocating lots of objects without
1643 destroying them does not show quadratic performance. Based on a proposal by
1644 Martin von Löwis at
1645 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1646
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001647- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001648 having been closed (for instance, a read() call could return some
1649 previously buffered data). Patch by Dmitry Vasiliev.
1650
Antoine Pitrou05608432009-01-09 18:53:14 +00001651- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1652 flag to work properly. Furthermore, when specifying -u, the text stdout
1653 and stderr streams have line-by-line buffering enabled (the default being
1654 to buffer arbitrary chunks of data).
1655
Raymond Hettinger35631532009-01-09 03:58:09 +00001656- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1657 instead of ints (reducing its size from 4 to 8 times thereby reducing
1658 Python's overall memory).
1659
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001660- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1661 an existing .py counterpart, override the co_filename attributes of all
1662 code objects if the original filename is obsolete (which can happen if the
1663 file has been renamed, moved, or if it is accessed through different paths).
1664 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1665
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001666- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1667 one byte. Also fixes the meaning of len() so that it returns the number of
1668 items, rather than the size in bytes.
1669
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001670- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1671
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001672- Issue #4747: When the terminal does not use utf-8, executing a script with
1673 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1674
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001675- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001676 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001677
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001678- Issue #3680: Reference cycles created through a dict, set or deque iterator
1679 did not get collected.
1680
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001681- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1682 where the tp_hash and tp_dict slots are both NULL.
1683
Georg Brandlccc47b62008-12-28 11:44:14 +00001684- Issue #4759: None is now allowed as the first argument of
1685 bytearray.translate(). It was always allowed for bytes.translate().
1686
Skip Montanaro80072cb2008-12-23 03:51:14 +00001687- Added test case to ensure attempts to read from a file opened for writing
1688 fail.
1689
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001690- Issue #3106: Speedup some comparisons (str/str and int/int).

1693 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1694
Antoine Pitrou621601a2008-12-17 23:18:19 +00001695- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1696 print elapsed times, not only when some objects are uncollectable /
1697 unreachable. Original patch by Neil Schemenauer.
1698
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001699- Issue #3439: Add a bit_length method to int.
1700
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001701- Issue #2173: When getting device encoding, check that return value of
1702 nl_langinfo is not the empty string. This was causing silent build
1703 failures on OS X.
1704
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001705- Issue #4597: Fixed several opcodes that weren't always propagating
1706 exceptions.
1707
1708- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001709 context manager returns a value that cannot be converted to a bool.
1710
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001711- Issue #4445: Replace "sizeof(PyBytesObject)" with
1712 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1713 bytes instances. On a typical machine this saves 3 bytes of memory
1714 (on average) per allocation of a bytes instance.
1715
Christian Heimesa872de52008-12-05 08:26:55 +00001716- Issue #4533: File read operation was dreadfully slow due to a slowly
1717 growing read buffer. Fixed by using the same growth rate algorithm as
1718 Python 2.x.
1719
Antoine Pitrou5504e892008-12-06 21:27:53 +00001720- Issue #4509: Various issues surrounding resize of bytearray objects to
1721 which there are buffer exports (e.g. memoryview instances).
1722
Georg Brandlf9734072008-12-07 15:30:06 +00001723- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1724 method on file objects with closefd=False. The file descriptor is still
1725 kept open but the file object behaves like a closed file. The ``FileIO``
1726 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001727
Antoine Pitroubc420402008-12-07 20:14:49 +00001728- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1734
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001735- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1736 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1737 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1738 of using the replace error handler in PyUnicode_DecodeUTF8().
