Victor Stinner00d6a1d2010-03-25 01:02:29 +000015- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, compiler
16 optimizations are disabled when --with-pydebug is used.
17
Victor Stinner120c2122010-03-25 00:30:28 +000018- Issue #8226: sys.setfilesystemencoding() raises a LookupError if the encoding
19 is unknown
20

25
Mark Dickinsonf673f0c2010-03-13 09:48:39 +000026- Issue #7845: Rich comparison methods on the complex type now return
27 NotImplemented rather than raising a TypeError when comparing with an
28 incompatible type; this allows user-defined classes to implement their own
29 comparisons with complex.
30
Victor Stinner52f6dd72010-03-12 14:45:56 +000031- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
32 (SIGINT). If an error occurs while importing the site module, the error is
33 printed and Python exits. Initialize the GIL before importing the site
34 module.
35
Benjamin Petersonae5f2f42010-03-07 17:10:51 +000036- Issue #7173: Generator finalization could invalidate sys.exc_info().

60 PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string
61 and PyOS_string_to_double instead. See issue #5835 for the original
62 deprecations.
63
Antoine Pitrou05b7c562010-02-02 22:47:00 +000064- Issue #7385: Fix a crash in `MemoryView_FromObject` when
65 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
66
Mark Dickinsonbc099642010-01-29 17:27:24 +000067- Issue #7788: Fix an interpreter crash produced by deleting a list
68 slice with very large step value.
69
Eric Smithf7bb5782010-01-27 00:44:57 +000070- Issue #7766: Change sys.getwindowsversion() return value to a named
71 tuple and add the additional members returned in an OSVERSIONINFOEX
72 structure. The new members are service_pack_major, service_pack_minor,
73 suite_mask, and product_type.
74
Antoine Pitroufc8d6f42010-01-17 12:38:54 +000075- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
76 could crash in many places because of the PyByteArray_AS_STRING() macro
77 returning NULL. The macro now returns a statically allocated empty
78 string instead.
79
Antoine Pitroub7fbcd32010-01-16 18:37:38 +000080- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
81 where the right hand operand is a set of constants, by turning the set into
82 a frozenset and pre-building it as a constant. The comparison operation
83 is made against the constant instead of building a new set each time it is
84 executed (a similar optimization already existed which turned a list of
85 constants into a pre-built tuple). Patch and additional tests by Dave
86 Malcolm.
87
Antoine Pitrouf2c54842010-01-13 08:07:53 +000088- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
89 methods of bytes, bytearray and unicode objects by using a common
90 implementation based on stringlib's fast search. Patch by Florent Xicluna.
91
Mark Dickinson45b63652010-01-16 18:10:25 +000092- Issue #7632: Fix various str -> float conversion bugs present in 2.7
93 alpha 2, including: (1) a serious 'wrong output' bug that could
94 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
95 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +000096 strings corresponding to subnormal values, (3) a memory leak for
97 some values large enough to cause overflow, and (4) a number of
98 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +000099
Benjamin Petersonaea44282010-01-04 01:10:28 +0000100- The __complex__ method is now looked up on the class of instances to make it

110 negative zero) in ** operator. The behaviour now conforms to that
111 described in C99 Annex F.
112
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000113- Issue #1811: improve accuracy and cross-platform consistency for
114 true division of integers: the result of a/b is now correctly
115 rounded for ints a and b (at least on IEEE 754 platforms), and in
116 particular does not depend on the internal representation of an int.
117
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000118- Issue #6834: replace the implementation for the 'python' and 'pythonw'
119 executables on OSX.
120
121 These executables now work properly with the arch(1) command:
122 ``arch -ppc python`` will start a universal binary version of python
123 in PPC mode (unlike previous releases).
124
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000125- Issue #7466: segmentation fault when the garbage collector is called

140 implement the relevant rich comparison methods.
141
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000142- Issue #7298: fixes for range and reversed(range(...)). Iteration
143 over range(a, b, c) incorrectly gave an empty iterator when a, b and
144 c fit in C long but the length of the range did not. Also fix
145 several cases where reversed(range(a, b, c)) gave wrong results, and
146 fix a refleak for reversed(range(a, b, c)) with large arguments.
147
Raymond Hettingerfc438512009-11-01 20:55:33 +0000148- Issue #7244: itertools.izip_longest() no longer ignores exceptions

256 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
257 PyArg_VaParseTupleAndKeywords and PyArg_Parse now raise a
258 DeprecationWarning for float arguments passed with the 'L' format
259 code. This will become a TypeError in a future version of Python,
260 to match the behaviour of the other integer format codes.

352 The default of restore_signals=True is a new behavior compared to earlier
353 Python versions. This means that signals such as SIGPIPE are not ignored
354 by default in subprocesses launched by Python (Issue #1652).

Antoine Pitrou45d61a32009-11-13 22:35:18 +0000620- Issue #7318: multiprocessing now uses a timeout when it fails to establish
621 a connection with another process, rather than looping endlessly. The
622 default timeout is 20 seconds, which should be amply sufficient for
623 local connections.

638 recursive locks as fast as regular non-recursive locks (previously,
639 they were slower by 10x to 15x).

659 reading from stdin so that existing input does not confuse it and

985 is run with the -OO flag. Tests requiring docstrings are skipped.
986

1015 a test fails. Can be combined with -j.
1016
Antoine Pitrou060cee22009-11-13 16:29:04 +00001017- Issue #6551: test_zipimport could import and then destroy some modules of
1018 the encodings package, which would make other tests fail further down
1019 the road because the internally cached encoders and decoders would point
1020 to empty global variables.
1021
Antoine Pitrou941ee882009-11-11 20:59:38 +00001022- Issue #7295: Do not use a hardcoded file name in test_tarfile.

1028 tests instead of tempfile.tempdir. This prevents the tests from sharing state
1029 between concurrent executions on the same system.
1030
Brett Cannon0ae45112009-11-05 01:17:22 +00001031- Issue #7248: In importlib.test.source.util a try/finally block did not make
1032 sure that some referenced objects actually were created in the block before
1033 calling methods on the object.
1034
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001035- Issue #7222: Make thread "reaping" more reliable so that reference
1036 leak-chasing test runs give sensible results. The previous method of
1037 reaping threads could return successfully while some Thread objects were
1038 still referenced. This also introduces a new private function:
1039 :func:`_thread._count()`.
1040
R. David Murray27144602009-10-19 15:26:16 +00001041- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1042 longer runs the risk of causing the worker thread to fail.
1043
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001044- Issue #7055: test___all__ now greedily detects all modules which have an
1045 __all__ attribute, rather than using a hardcoded and incomplete list.
1046
R. David Murray0bc11ae2009-10-18 22:18:17 +00001047- Issue #7058: Added save/restore for things like sys.argv and cwd to
1048 runtest_inner in regrtest, with warnings if the called test modifies them,
1049 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001050
Mark Dickinson2e304402009-10-04 18:43:54 +00001051- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1052
Brett Cannon3c273842009-07-20 00:14:29 +00001053- Fixed tests in importlib.test.source.test_abc_loader that were masking
1054 the proper exceptions that should be raised for missing or improper code
1055 object bytecode.
1056
Brett Cannonb49c70c2009-07-15 04:08:33 +00001057- Removed importlib's custom test discovery code and switched to
1058 unittest.TestLoader.discover().

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00001210- Issue #5829: complex("1e500") no longer raises OverflowError. This
1211 makes it consistent with float("1e500") and interpretation of real
1212 and imaginary literals.
1213

Mark Dickinsond1ec8b22009-05-11 15:45:15 +00001218- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
1219 (1) inf and nan strings with trailing whitespace were incorrectly
1220 rejected; (2) parsing of strings representing infinities and nans
1221 was locale aware; and (3) the interpretation of fromhex('-nan')
1222 didn't match that of float('-nan').

1325Core and Builtins
1326-----------------
1327
Mark Dickinson865e01a2009-05-07 16:37:01 +00001328- Issue #5914: Add new C API function PyOS_string_to_double, and
1329 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1330
Eric Smith741191f2009-05-06 13:08:15 +00001331- Issue #3382: float.__format__, complex.__format__, and %-formatting
1332 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1333 affects nan -> NAN and inf -> INF.
1334
Mark Hammond5a607a32009-05-06 08:04:54 +00001335- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1336 in all operations, including splitdrive, split, etc. splitunc() now issues
1337 a PendingDeprecation warning.
1338
Eric Smith63376222009-05-05 14:04:18 +00001339- Issue #5920: For float.__format__, change the behavior with the
1340 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1341 to be like 'g' but with at least one decimal point and with a
1342 default precision of 12. Previously, the behavior the same but with
1343 a default precision of 6. This more closely matches str(), and
1344 reduces surprises when adding alignment flags to the empty
1345 presentation type. This also affects the new complex.__format__ in
1346 the same way.
1347
Martin v. Löwis011e8422009-05-05 04:43:17 +00001348- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1349
R. David Murrayb18500d2009-05-04 22:59:07 +00001350- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1351 shadowed by classtype's, even if it was None. property now
1352 inserts the __doc__ into the subclass instance __dict__.
1353
Antoine Pitrou244651a2009-05-04 18:56:13 +00001354- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1355 sequences. Patch by Nick Barnes and Victor Stinner.
1356
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001357- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001358
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001359- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1360 received a new method, detach(). detach() disconnects the underlying stream
1361 from the buffer or text IO and returns it.
1362
Mark Dickinson33841c32009-05-01 15:37:04 +00001363- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1364 floats with absolute value over 1e50. Also remove length
1365 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1366 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001367
Eric Smith741191f2009-05-06 13:08:15 +00001368- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001369 format(complex(1, 2./3), '.5') now produces a sensible result.
1370
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001371- Issue #5864: Fix empty format code formatting for floats so that it
1372 never gives more than the requested number of significant digits.
1373
Eric Smith6dc46f52009-04-27 20:39:49 +00001374- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1375 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1376
Eric Smithcc32a112009-04-26 21:35:14 +00001377- Issue #5835: Deprecate PyOS_ascii_formatd.
1378
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001379- Issue #4971: Fix titlecase for characters that are their own
1380 titlecase, but not their own uppercase.
1381
Benjamin Peterson193152c2009-04-25 01:08:45 +00001382- Issue #5283: Setting __class__ in __del__ caused a segfault.
1383
Mark Dickinsonad476da2009-04-23 19:14:16 +00001384- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1385 z involves nans, infs or negative zeros.
1386
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001387- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001388
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001389- Issue #1869 (and many duplicates): make round(x, n) correctly
1390 rounded for a float x, by using the decimal <-> binary conversions
1391 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1392 consistently agrees with format(x, '.2f').
1393
Benjamin Petersonae937c02009-04-18 20:54:08 +00001394- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1395 some builtin types.
1396
Eric Smith0923d1d2009-04-16 20:16:10 +00001397- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1398
Eric Smith35e84722009-04-16 20:21:28 +00001399- Issue #5515: str.format() type 'n' combined with commas and leading
1400 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001401
1402- Implement PEP 378, Format Specifier for Thousands Separator, for
1403 floats.
1404
Mark Dickinson3370cce2009-04-17 22:40:53 +00001405- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001406 1e11, not 1e12. This avoids printing 13 significant digits in
1407 situations where only 12 of them are correct. Example problem
1408 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1409 long time.)
1410
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001411- Issue #1580: On most platforms, use a 'short' float repr: for a
1412 finite float x, repr(x) now outputs a string based on the shortest
1413 sequence of decimal digits that rounds to x. Previous behaviour was
1414 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001415 Another minor difference is that the new repr switches to
1416 exponential notation at 1e16 instead of the previous 1e17; this
1417 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001418
1419 There's a new sys attribute sys.float_repr_style, which takes
1420 the value 'short' to indicate that we're using short float repr,
1421 and 'legacy' if the short float repr isn't available for one
1422 reason or another.
1423
1424 The float repr change involves incorporating David Gay's 'perfect
1425 rounding' code into the Python core (it's in Python/dtoa.c). As a
1426 secondary consequence, all string-to-float and float-to-string
1427 conversions (including all float formatting operations) will be
1428 correctly rounded on these platforms.
1429
1430 See issue 1580 discussions for details of platforms for which
1431 this change does not apply.
1432
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001433- Issue #5759: float() didn't call __float__ on str subclasses.
1434
Georg Brandlabc38772009-04-12 15:51:51 +00001435- The string.maketrans() function is deprecated; there is a new static method
1436 maketrans() on the bytes and bytearray classes. This removes confusion about
1437 the types string.maketrans() is supposed to work with, and mirrors the
1438 methods available on the str class.
1439
R. David Murraydc6da8a2009-04-09 22:16:43 +00001440- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1441 its clarity and its speed.
1442
Matthias Klose091c7b12009-04-07 13:24:27 +00001443- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1444 to avoid compiler warnings.
1445
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001446- Issue #3739: The unicode-internal encoder now reports the number of characters
1447 consumed like any other encoder (instead of the number of bytes).

Vinay Sajip6268cbc2009-01-21 00:19:28 +00001792- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001793 having been closed (for instance, a read() call could return some
1794 previously buffered data). Patch by Dmitry Vasiliev.
1795
Antoine Pitrou05608432009-01-09 18:53:14 +00001796- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1797 flag to work properly. Furthermore, when specifying -u, the text stdout
1798 and stderr streams have line-by-line buffering enabled (the default being
1799 to buffer arbitrary chunks of data).
1800
Raymond Hettinger35631532009-01-09 03:58:09 +00001801- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1802 instead of ints (reducing its size from 4 to 8 times thereby reducing
1803 Python's overall memory).
1804
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001805- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1806 an existing .py counterpart, override the co_filename attributes of all
1807 code objects if the original filename is obsolete (which can happen if the
1808 file has been renamed, moved, or if it is accessed through different paths).
1809 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1810
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001811- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1812 one byte. Also fixes the meaning of len() so that it returns the number of
1813 items, rather than the size in bytes.
1814
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001815- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1816
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001817- Issue #4747: When the terminal does not use utf-8, executing a script with
1818 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1819
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001820- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001821 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001822
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001823- Issue #3680: Reference cycles created through a dict, set or deque iterator
1824 did not get collected.
1825
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001826- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1827 where the tp_hash and tp_dict slots are both NULL.
1828
Georg Brandlccc47b62008-12-28 11:44:14 +00001829- Issue #4759: None is now allowed as the first argument of
1830 bytearray.translate(). It was always allowed for bytes.translate().
1831
Skip Montanaro80072cb2008-12-23 03:51:14 +00001832- Added test case to ensure attempts to read from a file opened for writing
1833 fail.
1834
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001835- Issue #3106: Speedup some comparisons (str/str and int/int).
1836
Antoine Pitrouf289ae62008-12-18 11:06:25 +00001837- Issue #2183: Simplify and optimize bytecode for list, dict and set
1838 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1839
Antoine Pitrou621601a2008-12-17 23:18:19 +00001840- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1841 print elapsed times, not only when some objects are uncollectable /
1842 unreachable. Original patch by Neil Schemenauer.
1843
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001844- Issue #3439: Add a bit_length method to int.
1845
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001846- Issue #2173: When getting device encoding, check that return value of
1847 nl_langinfo is not the empty string. This was causing silent build
1848 failures on OS X.
1849
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001850- Issue #4597: Fixed several opcodes that weren't always propagating
1851 exceptions.
1852
1853- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001854 context manager returns a value that cannot be converted to a bool.
1855
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001856- Issue #4445: Replace "sizeof(PyBytesObject)" with
1857 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1858 bytes instances. On a typical machine this saves 3 bytes of memory
1859 (on average) per allocation of a bytes instance.
1860
Christian Heimesa872de52008-12-05 08:26:55 +00001861- Issue #4533: File read operation was dreadfully slow due to a slowly
1862 growing read buffer. Fixed by using the same growth rate algorithm as
1863 Python 2.x.
1864
Antoine Pitrou5504e892008-12-06 21:27:53 +00001865- Issue #4509: Various issues surrounding resize of bytearray objects to
1866 which there are buffer exports (e.g. memoryview instances).
1867
Georg Brandlf9734072008-12-07 15:30:06 +00001868- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1869 method on file objects with closefd=False. The file descriptor is still
1870 kept open but the file object behaves like a closed file. The ``FileIO``
1871 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001872
Antoine Pitroubc420402008-12-07 20:14:49 +00001873- Issue #4569: Interpreter crash when mutating a memoryview with an item size
1874 larger than 1.

1879
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001880- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1881 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1882 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1883 of using the replace error handler in PyUnicode_DecodeUTF8().
