12Core and Builtins
13-----------------
14
Benjamin Peterson23e018a2010-02-27 17:40:01 +000015- Handle errors from looking up __prepare__ correctly.
16
Larry Hastings1373a072010-02-24 22:49:58 +000017- Issue #5939: Add additional runtime checking to ensure a valid capsule
18 in Modules/_ctypes/callproc.c.
19
Eric Smith0facd772010-02-24 15:42:29 +000020- Issue #7309: Fix unchecked attribute access when converting
21 UnicodeEncodeError, UnicodeDecodeError, and UnicodeTranslateError to
22 strings.
23
Eric Smithabb28c62010-02-23 00:22:24 +000024- Issue #6902: Fix problem with built-in types format incorrectly with
25 0 padding.
26
Eric Smith4e260c52010-02-22 18:54:44 +000027- Issue #7988: Fix default alignment to be right aligned for
28 complex.__format__. Now it matches other numeric types.
29
Eric Smith68af50b2010-02-22 14:58:30 +000030- Issue #5988: Remove deprecated functions PyOS_ascii_formatd,
31 PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string
32 and PyOS_string_to_double instead. See issue #5835 for the original
33 deprecations.
34
Antoine Pitrou05b7c562010-02-02 22:47:00 +000035- Issue #7385: Fix a crash in `MemoryView_FromObject` when
36 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
37
Mark Dickinsonbc099642010-01-29 17:27:24 +000038- Issue #7788: Fix an interpreter crash produced by deleting a list
39 slice with very large step value.
40
Eric Smithf7bb5782010-01-27 00:44:57 +000041- Issue #7766: Change sys.getwindowsversion() return value to a named
42 tuple and add the additional members returned in an OSVERSIONINFOEX
43 structure. The new members are service_pack_major, service_pack_minor,
44 suite_mask, and product_type.
45
Antoine Pitroufc8d6f42010-01-17 12:38:54 +000046- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
47 could crash in many places because of the PyByteArray_AS_STRING() macro
48 returning NULL. The macro now returns a statically allocated empty
49 string instead.
50
Antoine Pitroub7fbcd32010-01-16 18:37:38 +000051- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
52 where the right hand operand is a set of constants, by turning the set into
53 a frozenset and pre-building it as a constant. The comparison operation
54 is made against the constant instead of building a new set each time it is
55 executed (a similar optimization already existed which turned a list of
56 constants into a pre-built tuple). Patch and additional tests by Dave
57 Malcolm.
58
Antoine Pitrouf2c54842010-01-13 08:07:53 +000059- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
60 methods of bytes, bytearray and unicode objects by using a common
61 implementation based on stringlib's fast search. Patch by Florent Xicluna.
62
Mark Dickinson45b63652010-01-16 18:10:25 +000063- Issue #7632: Fix various str -> float conversion bugs present in 2.7
64 alpha 2, including: (1) a serious 'wrong output' bug that could
65 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
66 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +000067 strings corresponding to subnormal values, (3) a memory leak for
68 some values large enough to cause overflow, and (4) a number of
69 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +000070
Benjamin Petersonaea44282010-01-04 01:10:28 +000071- The __complex__ method is now looked up on the class of instances to make it
72 consistent with other special methods.
73
Antoine Pitrouda2ecaf2010-01-02 21:40:36 +000074- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
75 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
76
Benjamin Petersond12362a2009-12-30 19:44:54 +000077- Issue #7604: Deleting an unset slotted attribute did not raise an
78 AttributeError.
79
Mark Dickinson9ab44b52009-12-30 16:22:49 +000080- Issue #7534: Fix handling of IEEE specials (infinities, nans,
81 negative zero) in ** operator. The behaviour now conforms to that
82 described in C99 Annex F.
83
Mark Dickinsoncbb62742009-12-27 15:09:50 +000084- Issue #1811: improve accuracy and cross-platform consistency for
85 true division of integers: the result of a/b is now correctly
86 rounded for ints a and b (at least on IEEE 754 platforms), and in
87 particular does not depend on the internal representation of an int.
88
Ronald Oussoren6f6c5622009-12-24 14:03:19 +000089- Issue #6834: replace the implementation for the 'python' and 'pythonw'
90 executables on OSX.
91
92 These executables now work properly with the arch(1) command:
93 ``arch -ppc python`` will start a universal binary version of python
94 in PPC mode (unlike previous releases).
95
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +000096- Issue #7466: segmentation fault when the garbage collector is called
97 in the middle of populating a tuple. Patch by Florent Xicluna.
98

100 with invalid values.
101
Amaury Forgeot d'Arc7d0bddd2009-11-30 00:08:56 +0000102- Issue #6077: On Windows, files opened with tempfile.TemporaryFile in "wt+"
103 mode would appear truncated on the first '0x1a' byte (aka. Ctrl+Z).
104
Ronald Oussoren3c1928a2009-11-19 17:15:31 +0000105- Issue #7085: Fix crash when importing some extensions in a thread
106 on MacOSX 10.6.
107
Philip Jenvey1309adb2009-11-17 03:43:14 +0000108- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
109
Mark Dickinson6f1d0492009-11-15 13:58:49 +0000110- Issue #6970: Remove redundant calls when comparing objects that don't
111 implement the relevant rich comparison methods.
112
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000113- Issue #7298: fixes for range and reversed(range(...)). Iteration
114 over range(a, b, c) incorrectly gave an empty iterator when a, b and
115 c fit in C long but the length of the range did not. Also fix
116 several cases where reversed(range(a, b, c)) gave wrong results, and
117 fix a refleak for reversed(range(a, b, c)) with large arguments.
118
Raymond Hettingerfc438512009-11-01 20:55:33 +0000119- Issue #7244: itertools.izip_longest() no longer ignores exceptions

128
Antoine Pitroub6ef9632009-10-24 20:47:05 +0000129- Support for AtheOS has been completely removed from the code base. It was
130 disabled since Python 3.0.
131
132- Support for several legacy threading libraries has been disabled. These
133 libraries are: Mach C threads, SunOS LWP, GNU pth, Irix threads. Support code
134 will be entirely removed in 3.3.

325
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000326- Issue #6939: Fix file I/O objects in the `io` module to keep the original
327 file position when calling `truncate()`. It would previously change the
328 file position to the given argument, which goes against the tradition of
329 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
330
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000331- Issue #7610: Reworked implementation of the internal
332 :class:`zipfile.ZipExtFile` class used to represent files stored inside
333 an archive. The new implementation is significantly faster and can
334 be wrapped in a :class:`io.BufferedReader` object for more speedups.
335 It also solves an issue where interleaved calls to `read()` and
336 `readline()` give wrong results. Patch by Nir Aides.
337
Jesse Noller1f0b6582010-01-27 03:36:01 +0000338- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,

498
Nick Coghlan260bd3e2009-11-16 06:49:25 +0000499- Issue #6816: runpy now provides a run_path function that allows Python code
500 to execute file paths that refer to source or compiled Python files as well
501 as zipfiles, directories and other valid sys.path entries that contain a
502 __main__.py file. This allows applications that run other Python scripts to
503 support the same flexibility as the CPython command line itself.
504
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000505- Issue #7318: multiprocessing now uses a timeout when it fails to establish
506 a connection with another process, rather than looping endlessly. The

540 a modification is done through it. This fixes inconsistencies and test
541 failures on systems with slightly bogus mtime behaviour.
542
Gregory P. Smith50467882009-11-01 18:42:17 +0000543- Issue #7246 & Issue #7208: getpass now properly flushes input before
544 reading from stdin so that existing input does not confuse it and
545 lead to incorrect entry or an IOError. It also properly flushes it
546 afterwards to avoid the terminal echoing the input afterwards on
547 OSes such as Solaris.

683
Brett Cannon64ef00f2009-07-20 03:19:18 +0000684- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like

828 filesystem encoding.
829
R. David Murray378c0cf2010-02-24 01:46:21 +0000830- Issue #6292: for the moment at least, the test suite runs cleanly if python

844
R. David Murray445448c2009-12-20 17:28:31 +0000845- Issue #7376: instead of running a self-test (which was failing) when called

854 file in the Lib/test directory, which might be read-only for the
855 user running the tests.
856
R. David Murray35768ad2009-11-15 00:23:21 +0000857- Issue #7324: add a sanity check to regrtest argument parsing to

861 a test fails. Can be combined with -j.
862
Antoine Pitrou060cee22009-11-13 16:29:04 +0000863- Issue #6551: test_zipimport could import and then destroy some modules of
864 the encodings package, which would make other tests fail further down
865 the road because the internally cached encoders and decoders would point
866 to empty global variables.
867
Antoine Pitrou941ee882009-11-11 20:59:38 +0000868- Issue #7295: Do not use a hardcoded file name in test_tarfile.

882 leak-chasing test runs give sensible results. The previous method of
883 reaping threads could return successfully while some Thread objects were
884 still referenced. This also introduces a new private function:
885 :func:`_thread._count()`.
886
R. David Murray27144602009-10-19 15:26:16 +0000887- Issue #7151: fixed regrtest -j so that output to stderr from a test no

889
Antoine Pitrou4de39cd2009-10-10 21:08:31 +0000890- Issue #7055: test___all__ now greedily detects all modules which have an

898
Brett Cannon3c273842009-07-20 00:14:29 +0000899- Fixed tests in importlib.test.source.test_abc_loader that were masking
900 the proper exceptions that should be raised for missing or improper code
901 object bytecode.
902
Brett Cannonb49c70c2009-07-15 04:08:33 +0000903- Removed importlib's custom test discovery code and switched to

1093 than an int, which makes some operations possible under 64-bit Linux (e.g.

Mark Dickinson865e01a2009-05-07 16:37:01 +00001174- Issue #5914: Add new C API function PyOS_string_to_double, and
1175 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1176
Eric Smith741191f2009-05-06 13:08:15 +00001177- Issue #3382: float.__format__, complex.__format__, and %-formatting
1178 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1179 affects nan -> NAN and inf -> INF.
1180
Mark Hammond5a607a32009-05-06 08:04:54 +00001181- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1182 in all operations, including splitdrive, split, etc. splitunc() now issues
1183 a PendingDeprecation warning.
1184
Eric Smith63376222009-05-05 14:04:18 +00001185- Issue #5920: For float.__format__, change the behavior with the
1186 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1187 to be like 'g' but with at least one decimal point and with a
1188 default precision of 12. Previously, the behavior the same but with
1189 a default precision of 6. This more closely matches str(), and
1190 reduces surprises when adding alignment flags to the empty
1191 presentation type. This also affects the new complex.__format__ in
1192 the same way.
1193
Martin v. Löwis011e8422009-05-05 04:43:17 +00001194- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00001205- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1206 received a new method, detach(). detach() disconnects the underlying stream
1207 from the buffer or text IO and returns it.
1208
Mark Dickinson33841c32009-05-01 15:37:04 +00001209- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1210 floats with absolute value over 1e50. Also remove length
1211 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1212 12.34 no longer raise an exception.

Eric Smith58a42242009-04-30 01:00:33 +00001215 format(complex(1, 2./3), '.5') now produces a sensible result.
1216
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001217- Issue #5864: Fix empty format code formatting for floats so that it
1218 never gives more than the requested number of significant digits.
1219
Eric Smith6dc46f52009-04-27 20:39:49 +00001220- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

1226 titlecase, but not their own uppercase.
1227
Benjamin Peterson193152c2009-04-25 01:08:45 +00001228- Issue #5283: Setting __class__ in __del__ caused a segfault.
1229
Mark Dickinsonad476da2009-04-23 19:14:16 +00001230- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1231 z involves nans, infs or negative zeros.
1232
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001233- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001234
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001235- Issue #1869 (and many duplicates): make round(x, n) correctly
1236 rounded for a float x, by using the decimal <-> binary conversions
1237 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1238 consistently agrees with format(x, '.2f').
1239
Benjamin Petersonae937c02009-04-18 20:54:08 +00001240- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1241 some builtin types.
1242
Eric Smith0923d1d2009-04-16 20:16:10 +00001243- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1244
Eric Smith35e84722009-04-16 20:21:28 +00001245- Issue #5515: str.format() type 'n' combined with commas and leading
1246 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001247
1248- Implement PEP 378, Format Specifier for Thousands Separator, for
1249 floats.
1250
Mark Dickinson3370cce2009-04-17 22:40:53 +00001251- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001252 1e11, not 1e12. This avoids printing 13 significant digits in
1253 situations where only 12 of them are correct. Example problem
1254 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1255 long time.)
1256
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001257- Issue #1580: On most platforms, use a 'short' float repr: for a
1258 finite float x, repr(x) now outputs a string based on the shortest
1259 sequence of decimal digits that rounds to x. Previous behaviour was
1260 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001261 Another minor difference is that the new repr switches to
1262 exponential notation at 1e16 instead of the previous 1e17; this
1263 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001264
1265 There's a new sys attribute sys.float_repr_style, which takes
1266 the value 'short' to indicate that we're using short float repr,
1267 and 'legacy' if the short float repr isn't available for one
1268 reason or another.
1269
1270 The float repr change involves incorporating David Gay's 'perfect
1271 rounding' code into the Python core (it's in Python/dtoa.c). As a
1272 secondary consequence, all string-to-float and float-to-string
1273 conversions (including all float formatting operations) will be
1274 correctly rounded on these platforms.
1275
1276 See issue 1580 discussions for details of platforms for which
1277 this change does not apply.
1278
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001279- Issue #5759: float() didn't call __float__ on str subclasses.
1280
Georg Brandlabc38772009-04-12 15:51:51 +00001281- The string.maketrans() function is deprecated; there is a new static method
1282 maketrans() on the bytes and bytearray classes. This removes confusion about
1283 the types string.maketrans() is supposed to work with, and mirrors the
1284 methods available on the str class.
1285
R. David Murraydc6da8a2009-04-09 22:16:43 +00001286- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

1291
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001292- Issue #3739: The unicode-internal encoder now reports the number of characters

1449
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001450- Issue #4688: Add a heuristic so that tuples and dicts containing only
1451 untrackable objects are not tracked by the garbage collector. This can
1452 reduce the size of collections and therefore the garbage collection overhead
1453 on long-running programs, depending on their particular use of datatypes.

1467 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1468 and sizeof(Py_UNICODE) == 2.
1469
Eric Smith8ec90442009-03-14 12:29:34 +00001470- Issue #5237: Allow auto-numbered fields in str.format(). For

1522
Lars Gustäbel42e00912009-03-22 20:34:29 +00001523- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1524 forever on incomplete input. That caused tarfile.open() to hang when used
1525 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1526 partial bzip2 compressed data.
1527
Mark Dickinson79f52032009-03-17 23:12:51 +00001528- Issue #2110: Add support for thousands separator and 'n' type

Mark Dickinsonb40b9472009-03-29 16:58:21 +00001547 struct.error instead of returning b'\xff\xff\xff\xff'. The
1548 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants

1568 contained non ascii character on windows.
1569
Benjamin Petersonf5b52242009-03-02 23:31:26 +00001570- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
1571 source has already been decoded into str.
1572
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00001573- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
1574 rotating the object pointer by 4 bits to the right.
1575
Mark Dickinson87ec0852009-02-09 17:15:59 +00001576- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1577 it now forces its argument to double before testing for infinity.
1578
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001579- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1580 returns a non-number type.
1581
Benjamin Peterson87618552009-02-08 15:00:52 +00001582- Issue #5182: Removed memoryview.__str__.

1587 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001588
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001589- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001590 were suppressing all exceptions. These include list() and bytearray().
1591
Mark Dickinson1124e712009-01-28 21:25:58 +00001592- Issue #4707: round(x, n) now returns an integer if x is an integer.
1593 Previously it returned a float.
1594
Antoine Pitroub52ec782009-01-25 16:34:23 +00001595- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1596 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1597 evaluation loop is compiled with a new dispatch mechanism which gives
1598 speedups of up to 20%, depending on the system, on various benchmarks.
1599
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001600- Issue #4874: Most builtin decoders now reject unicode input.

1603 from a string.
1604
Benjamin Peterson05e782f2009-01-19 15:15:02 +00001605- Issue #4991: os.fdopen now raises an OSError for invalid file descriptors.
1606
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001607- Issue #4838: When a module is deallocated, free the memory backing the
1608 optional module state data.
1609
Mark Dickinson8055afd2009-01-17 10:04:45 +00001610- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1611 type to (void *).
1612
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001613- Issue #4935: The overflow checking code in the expandtabs() method common
1614 to str, bytes and bytearray could be optimized away by the compiler, letting
1615 the interpreter segfault instead of raising an error.
1616
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001617- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1618 __next__ method.
1619
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001620- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1621 function no longer attempt to call the __long__ slot to convert an object
1622 to an integer. Only the __int__ and __trunc__ slots are examined.
1623
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001624- Issue #4893: Use NT threading on CE.
1625
Martin v. Löwisec59d042009-01-12 07:59:10 +00001626- Issue #4915: Port sysmodule to Windows CE.
1627
Antoine Pitrouab868312009-01-10 15:40:25 +00001628- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1629 common cases are optimized thanks to a dedicated fast path and a moderate
1630 amount of loop unrolling.
1631
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001632- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1633 collecting the oldest generation) so that allocating lots of objects without
1634 destroying them does not show quadratic performance. Based on a proposal by
1635 Martin von Löwis at
1636 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1637
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001638- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001639 having been closed (for instance, a read() call could return some
1640 previously buffered data). Patch by Dmitry Vasiliev.
1641
Antoine Pitrou05608432009-01-09 18:53:14 +00001642- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1643 flag to work properly. Furthermore, when specifying -u, the text stdout
1644 and stderr streams have line-by-line buffering enabled (the default being
1645 to buffer arbitrary chunks of data).
1646
Raymond Hettinger35631532009-01-09 03:58:09 +00001647- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1648 instead of ints (reducing its size from 4 to 8 times thereby reducing
1649 Python's overall memory).
1650
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001651- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1652 an existing .py counterpart, override the co_filename attributes of all
1653 code objects if the original filename is obsolete (which can happen if the
1654 file has been renamed, moved, or if it is accessed through different paths).
1655 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1656
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001657- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1658 one byte. Also fixes the meaning of len() so that it returns the number of
1659 items, rather than the size in bytes.
1660
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001661- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1662
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001663- Issue #4747: When the terminal does not use utf-8, executing a script with
1664 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1665
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001666- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001667 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001668
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001669- Issue #3680: Reference cycles created through a dict, set or deque iterator
1670 did not get collected.
1671
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001672- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1673 where the tp_hash and tp_dict slots are both NULL.
1674
Georg Brandlccc47b62008-12-28 11:44:14 +00001675- Issue #4759: None is now allowed as the first argument of
1676 bytearray.translate(). It was always allowed for bytes.translate().
1677
Skip Montanaro80072cb2008-12-23 03:51:14 +00001678- Added test case to ensure attempts to read from a file opened for writing
1679 fail.
1680
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001681- Issue #3106: Speedup some comparisons (str/str and int/int).

1685
Antoine Pitrou621601a2008-12-17 23:18:19 +00001686- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1687 print elapsed times, not only when some objects are uncollectable /
1688 unreachable. Original patch by Neil Schemenauer.
1689
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001690- Issue #3439: Add a bit_length method to int.
1691
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001692- Issue #2173: When getting device encoding, check that return value of
1693 nl_langinfo is not the empty string. This was causing silent build
1694 failures on OS X.
1695
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001696- Issue #4597: Fixed several opcodes that weren't always propagating
1697 exceptions.
1698
1699- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001700 context manager returns a value that cannot be converted to a bool.
1701
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001702- Issue #4445: Replace "sizeof(PyBytesObject)" with
1703 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1704 bytes instances. On a typical machine this saves 3 bytes of memory
1705 (on average) per allocation of a bytes instance.
1706
Christian Heimesa872de52008-12-05 08:26:55 +00001707- Issue #4533: File read operation was dreadfully slow due to a slowly
1708 growing read buffer. Fixed by using the same growth rate algorithm as
1709 Python 2.x.
1710
Antoine Pitrou5504e892008-12-06 21:27:53 +00001711- Issue #4509: Various issues surrounding resize of bytearray objects to
1712 which there are buffer exports (e.g. memoryview instances).
1713
Georg Brandlf9734072008-12-07 15:30:06 +00001714- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1715 method on file objects with closefd=False. The file descriptor is still
1716 kept open but the file object behaves like a closed file. The ``FileIO``
1717 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001718
Antoine Pitroubc420402008-12-07 20:14:49 +00001719- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1725
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001726- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1727 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1728 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1729 of using the replace error handler in PyUnicode_DecodeUTF8().
