10*Release date: XX-XXX-XXX*
11
12Core and Builtins
13-----------------
14
Mark Dickinson9ab44b52009-12-30 16:22:49 +000015- Issue #7534: Fix handling of IEEE specials (infinities, nans,
16 negative zero) in ** operator. The behaviour now conforms to that
17 described in C99 Annex F.
18
Mark Dickinsoncbb62742009-12-27 15:09:50 +000019- Issue #1811: improve accuracy and cross-platform consistency for
20 true division of integers: the result of a/b is now correctly
21 rounded for ints a and b (at least on IEEE 754 platforms), and in
22 particular does not depend on the internal representation of an int.
23
Ronald Oussoren6f6c5622009-12-24 14:03:19 +000024- Issue #6834: replace the implementation for the 'python' and 'pythonw'
25 executables on OSX.
26
27 These executables now work properly with the arch(1) command:
28 ``arch -ppc python`` will start a universal binary version of python
29 in PPC mode (unlike previous releases).
30
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +000031- Issue #7466: segmentation fault when the garbage collector is called
32 in the middle of populating a tuple. Patch by Florent Xicluna.
33
Amaury Forgeot d'Arc64f3ca42009-12-01 21:59:18 +000034- Issue #7419: setlocale() could crash the interpreter on Windows when called
35 with invalid values.
36

38 mode would appear truncated on the first '0x1a' byte (aka. Ctrl+Z).
39
Ronald Oussoren3c1928a2009-11-19 17:15:31 +000040- Issue #7085: Fix crash when importing some extensions in a thread

46 implement the relevant rich comparison methods.
47
Mark Dickinsond550c9a2009-11-15 09:57:26 +000048- Issue #7298: fixes for range and reversed(range(...)). Iteration
49 over range(a, b, c) incorrectly gave an empty iterator when a, b and
50 c fit in C long but the length of the range did not. Also fix
51 several cases where reversed(range(a, b, c)) gave wrong results, and
52 fix a refleak for reversed(range(a, b, c)) with large arguments.
53
Raymond Hettingerfc438512009-11-01 20:55:33 +000054- Issue #7244: itertools.izip_longest() no longer ignores exceptions

276
Nick Coghlan260bd3e2009-11-16 06:49:25 +0000277- Issue #6816: runpy now provides a run_path function that allows Python code
278 to execute file paths that refer to source or compiled Python files as well
279 as zipfiles, directories and other valid sys.path entries that contain a
280 __main__.py file. This allows applications that run other Python scripts to
281 support the same flexibility as the CPython command line itself.

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

568
Antoine Pitrou060cee22009-11-13 16:29:04 +0000569- Issue #6551: test_zipimport could import and then destroy some modules of
570 the encodings package, which would make other tests fail further down
571 the road because the internally cached encoders and decoders would point
572 to empty global variables.
573
Antoine Pitrou941ee882009-11-11 20:59:38 +0000574- Issue #7295: Do not use a hardcoded file name in test_tarfile.

872
Mark Dickinson865e01a2009-05-07 16:37:01 +0000873- Issue #5914: Add new C API function PyOS_string_to_double, and
874 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
875
Eric Smith741191f2009-05-06 13:08:15 +0000876- Issue #3382: float.__format__, complex.__format__, and %-formatting
877 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
878 affects nan -> NAN and inf -> INF.
879
Mark Hammond5a607a32009-05-06 08:04:54 +0000880- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
881 in all operations, including splitdrive, split, etc. splitunc() now issues
882 a PendingDeprecation warning.

Eric Smith63376222009-05-05 14:04:18 +0000884- Issue #5920: For float.__format__, change the behavior with the
885 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
886 to be like 'g' but with at least one decimal point and with a
887 default precision of 12. Previously, the behavior the same but with
888 a default precision of 6. This more closely matches str(), and
889 reduces surprises when adding alignment flags to the empty
890 presentation type. This also affects the new complex.__format__ in
891 the same way.

Benjamin Petersond2e0c792009-05-01 20:40:59 +0000904- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
905 received a new method, detach(). detach() disconnects the underlying stream
906 from the buffer or text IO and returns it.
907
Mark Dickinson33841c32009-05-01 15:37:04 +0000908- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
909 floats with absolute value over 1e50. Also remove length
910 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
911 12.34 no longer raise an exception.

Mark Dickinsone6a076d2009-04-18 11:48:33 +0000934- Issue #1869 (and many duplicates): make round(x, n) correctly
935 rounded for a float x, by using the decimal <-> binary conversions
936 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
937 consistently agrees with format(x, '.2f').
938
Benjamin Petersonae937c02009-04-18 20:54:08 +0000939- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

943
Eric Smith35e84722009-04-16 20:21:28 +0000944- Issue #5515: str.format() type 'n' combined with commas and leading

Eric Smith0923d1d2009-04-16 20:16:10 +0000946
947- Implement PEP 378, Format Specifier for Thousands Separator, for
948 floats.
949
Mark Dickinson3370cce2009-04-17 22:40:53 +0000950- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000951 1e11, not 1e12. This avoids printing 13 significant digits in
952 situations where only 12 of them are correct. Example problem
953 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
954 long time.)
955
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000956- Issue #1580: On most platforms, use a 'short' float repr: for a
957 finite float x, repr(x) now outputs a string based on the shortest
958 sequence of decimal digits that rounds to x. Previous behaviour was
959 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000960 Another minor difference is that the new repr switches to
961 exponential notation at 1e16 instead of the previous 1e17; this
962 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000963
964 There's a new sys attribute sys.float_repr_style, which takes
965 the value 'short' to indicate that we're using short float repr,
966 and 'legacy' if the short float repr isn't available for one
967 reason or another.
968
969 The float repr change involves incorporating David Gay's 'perfect
970 rounding' code into the Python core (it's in Python/dtoa.c). As a
971 secondary consequence, all string-to-float and float-to-string
972 conversions (including all float formatting operations) will be
973 correctly rounded on these platforms.
974
975 See issue 1580 discussions for details of platforms for which
976 this change does not apply.
977
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000978- Issue #5759: float() didn't call __float__ on str subclasses.
979
Georg Brandlabc38772009-04-12 15:51:51 +0000980- The string.maketrans() function is deprecated; there is a new static method
981 maketrans() on the bytes and bytearray classes. This removes confusion about
982 the types string.maketrans() is supposed to work with, and mirrors the
983 methods available on the str class.

1223 forever on incomplete input. That caused tarfile.open() to hang when used
1224 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1225 partial bzip2 compressed data.
1226
Mark Dickinson79f52032009-03-17 23:12:51 +00001227- Issue #2110: Add support for thousands separator and 'n' type

1231 '>' alignment characters.
1232
Antoine Pitrou0ae29cf2009-03-13 22:33:17 +00001233- The error detection code in FileIO.close() could fail to reflect the `errno`
1234 value, and report it as -1 instead.
1235
Antoine Pitroua28fcfd2009-03-13 23:42:55 +00001236- Issue #5016: FileIO.seekable() could return False if the file position

Mark Dickinsonae681df2009-03-21 10:26:31 +00001244- Issue #5463: In struct module, remove deprecated overflow wrapping
1245 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00001246 struct.error instead of returning b'\xff\xff\xff\xff'. The
1247 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
1248 have been removed from the struct module.

1264 used when using str.format() with str, int, and float arguments.
1265
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00001266- Issue #5249: time.strftime returned malformed string when format string
1267 contained non ascii character on windows.
1268
Benjamin Petersonf5b52242009-03-02 23:31:26 +00001269- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
1270 source has already been decoded into str.
1271
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00001272- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
1273 rotating the object pointer by 4 bits to the right.
1274
Mark Dickinson87ec0852009-02-09 17:15:59 +00001275- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1276 it now forces its argument to double before testing for infinity.
1277
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001278- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1279 returns a non-number type.
1280
Benjamin Peterson87618552009-02-08 15:00:52 +00001281- Issue #5182: Removed memoryview.__str__.

1286 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001287
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001288- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001289 were suppressing all exceptions. These include list() and bytearray().
1290
Mark Dickinson1124e712009-01-28 21:25:58 +00001291- Issue #4707: round(x, n) now returns an integer if x is an integer.
1292 Previously it returned a float.
1293
Antoine Pitroub52ec782009-01-25 16:34:23 +00001294- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1295 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1296 evaluation loop is compiled with a new dispatch mechanism which gives
1297 speedups of up to 20%, depending on the system, on various benchmarks.
1298
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001299- Issue #4874: Most builtin decoders now reject unicode input.

1302 from a string.
1303
Benjamin Peterson05e782f2009-01-19 15:15:02 +00001304- Issue #4991: os.fdopen now raises an OSError for invalid file descriptors.
1305
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001306- Issue #4838: When a module is deallocated, free the memory backing the
1307 optional module state data.
1308
Mark Dickinson8055afd2009-01-17 10:04:45 +00001309- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1310 type to (void *).
1311
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001312- Issue #4935: The overflow checking code in the expandtabs() method common
1313 to str, bytes and bytearray could be optimized away by the compiler, letting
1314 the interpreter segfault instead of raising an error.
1315
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001316- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1317 __next__ method.
1318
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001319- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1320 function no longer attempt to call the __long__ slot to convert an object
1321 to an integer. Only the __int__ and __trunc__ slots are examined.
1322
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001323- Issue #4893: Use NT threading on CE.
1324
Martin v. Löwisec59d042009-01-12 07:59:10 +00001325- Issue #4915: Port sysmodule to Windows CE.
1326
Antoine Pitrouab868312009-01-10 15:40:25 +00001327- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1328 common cases are optimized thanks to a dedicated fast path and a moderate
1329 amount of loop unrolling.
1330
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001331- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1332 collecting the oldest generation) so that allocating lots of objects without
1333 destroying them does not show quadratic performance. Based on a proposal by
1334 Martin von Löwis at
1335 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1336
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001337- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001338 having been closed (for instance, a read() call could return some
1339 previously buffered data). Patch by Dmitry Vasiliev.
1340
Antoine Pitrou05608432009-01-09 18:53:14 +00001341- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1342 flag to work properly. Furthermore, when specifying -u, the text stdout
1343 and stderr streams have line-by-line buffering enabled (the default being
1344 to buffer arbitrary chunks of data).
1345
Raymond Hettinger35631532009-01-09 03:58:09 +00001346- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1347 instead of ints (reducing its size from 4 to 8 times thereby reducing
1348 Python's overall memory).
1349
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001350- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1351 an existing .py counterpart, override the co_filename attributes of all
1352 code objects if the original filename is obsolete (which can happen if the
1353 file has been renamed, moved, or if it is accessed through different paths).
1354 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1355
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001356- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1357 one byte. Also fixes the meaning of len() so that it returns the number of
1358 items, rather than the size in bytes.
1359
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001360- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1361
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001362- Issue #4747: When the terminal does not use utf-8, executing a script with
1363 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1364
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001365- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001366 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001367
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001368- Issue #3680: Reference cycles created through a dict, set or deque iterator
1369 did not get collected.
1370
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001371- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1372 where the tp_hash and tp_dict slots are both NULL.
1373
Georg Brandlccc47b62008-12-28 11:44:14 +00001374- Issue #4759: None is now allowed as the first argument of
1375 bytearray.translate(). It was always allowed for bytes.translate().
1376
Skip Montanaro80072cb2008-12-23 03:51:14 +00001377- Added test case to ensure attempts to read from a file opened for writing
1378 fail.
1379
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001380- Issue #3106: Speedup some comparisons (str/str and int/int).

1384
Antoine Pitrou621601a2008-12-17 23:18:19 +00001385- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1386 print elapsed times, not only when some objects are uncollectable /
1387 unreachable. Original patch by Neil Schemenauer.
1388
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001389- Issue #3439: Add a bit_length method to int.
1390
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001391- Issue #2173: When getting device encoding, check that return value of
1392 nl_langinfo is not the empty string. This was causing silent build
1393 failures on OS X.
1394
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001395- Issue #4597: Fixed several opcodes that weren't always propagating
1396 exceptions.
1397
1398- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001399 context manager returns a value that cannot be converted to a bool.
1400
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001401- Issue #4445: Replace "sizeof(PyBytesObject)" with
1402 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1403 bytes instances. On a typical machine this saves 3 bytes of memory
1404 (on average) per allocation of a bytes instance.
1405
Christian Heimesa872de52008-12-05 08:26:55 +00001406- Issue #4533: File read operation was dreadfully slow due to a slowly
1407 growing read buffer. Fixed by using the same growth rate algorithm as
1408 Python 2.x.
1409
Antoine Pitrou5504e892008-12-06 21:27:53 +00001410- Issue #4509: Various issues surrounding resize of bytearray objects to
1411 which there are buffer exports (e.g. memoryview instances).
1412
Georg Brandlf9734072008-12-07 15:30:06 +00001413- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1414 method on file objects with closefd=False. The file descriptor is still
1415 kept open but the file object behaves like a closed file. The ``FileIO``
1416 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001417
Antoine Pitroubc420402008-12-07 20:14:49 +00001418- Issue #4569: Interpreter crash when mutating a memoryview with an item size
1419 larger than 1.

1424
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001425- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1426 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1427 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1428 of using the replace error handler in PyUnicode_DecodeUTF8().
