12Core and Builtins
13-----------------
14
Benjamin Petersond12362a2009-12-30 19:44:54 +000015- Issue #7604: Deleting an unset slotted attribute did not raise an
16 AttributeError.
17

19 negative zero) in ** operator. The behaviour now conforms to that
20 described in C99 Annex F.
21
Mark Dickinsoncbb62742009-12-27 15:09:50 +000022- Issue #1811: improve accuracy and cross-platform consistency for
23 true division of integers: the result of a/b is now correctly
24 rounded for ints a and b (at least on IEEE 754 platforms), and in
25 particular does not depend on the internal representation of an int.
26
Ronald Oussoren6f6c5622009-12-24 14:03:19 +000027- Issue #6834: replace the implementation for the 'python' and 'pythonw'
28 executables on OSX.
29
30 These executables now work properly with the arch(1) command:
31 ``arch -ppc python`` will start a universal binary version of python
32 in PPC mode (unlike previous releases).
33
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +000034- Issue #7466: segmentation fault when the garbage collector is called
35 in the middle of populating a tuple. Patch by Florent Xicluna.

50
Mark Dickinsond550c9a2009-11-15 09:57:26 +000051- Issue #7298: fixes for range and reversed(range(...)). Iteration
52 over range(a, b, c) incorrectly gave an empty iterator when a, b and
53 c fit in C long but the length of the range did not. Also fix
54 several cases where reversed(range(a, b, c)) gave wrong results, and
55 fix a refleak for reversed(range(a, b, c)) with large arguments.
56

281 to execute file paths that refer to source or compiled Python files as well
282 as zipfiles, directories and other valid sys.path entries that contain a

578 the road because the internally cached encoders and decoders would point
579 to empty global variables.
580

879
Mark Dickinson865e01a2009-05-07 16:37:01 +0000880- Issue #5914: Add new C API function PyOS_string_to_double, and
881 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
882
Eric Smith741191f2009-05-06 13:08:15 +0000883- Issue #3382: float.__format__, complex.__format__, and %-formatting
884 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
885 affects nan -> NAN and inf -> INF.
886
Mark Hammond5a607a32009-05-06 08:04:54 +0000887- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
888 in all operations, including splitdrive, split, etc. splitunc() now issues
889 a PendingDeprecation warning.
890
Eric Smith63376222009-05-05 14:04:18 +0000891- Issue #5920: For float.__format__, change the behavior with the
892 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
893 to be like 'g' but with at least one decimal point and with a
894 default precision of 12. Previously, the behavior the same but with
895 a default precision of 6. This more closely matches str(), and
896 reduces surprises when adding alignment flags to the empty
897 presentation type. This also affects the new complex.__format__ in
898 the same way.
899

Benjamin Petersond2e0c792009-05-01 20:40:59 +0000911- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
912 received a new method, detach(). detach() disconnects the underlying stream
913 from the buffer or text IO and returns it.
914
Mark Dickinson33841c32009-05-01 15:37:04 +0000915- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
916 floats with absolute value over 1e50. Also remove length
917 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %

Eric Smith741191f2009-05-06 13:08:15 +0000920- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000921 format(complex(1, 2./3), '.5') now produces a sensible result.
922
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000923- Issue #5864: Fix empty format code formatting for floats so that it

938
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000939- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000940
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000941- Issue #1869 (and many duplicates): make round(x, n) correctly
942 rounded for a float x, by using the decimal <-> binary conversions
943 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
944 consistently agrees with format(x, '.2f').
945
Benjamin Petersonae937c02009-04-18 20:54:08 +0000946- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
947 some builtin types.
948
Eric Smith0923d1d2009-04-16 20:16:10 +0000949- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
950
Eric Smith35e84722009-04-16 20:21:28 +0000951- Issue #5515: str.format() type 'n' combined with commas and leading
952 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000953
954- Implement PEP 378, Format Specifier for Thousands Separator, for
955 floats.
956
Mark Dickinson3370cce2009-04-17 22:40:53 +0000957- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000958 1e11, not 1e12. This avoids printing 13 significant digits in
959 situations where only 12 of them are correct. Example problem
960 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
961 long time.)
962
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000963- Issue #1580: On most platforms, use a 'short' float repr: for a
964 finite float x, repr(x) now outputs a string based on the shortest
965 sequence of decimal digits that rounds to x. Previous behaviour was
966 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000967 Another minor difference is that the new repr switches to
968 exponential notation at 1e16 instead of the previous 1e17; this
969 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000970
971 There's a new sys attribute sys.float_repr_style, which takes
972 the value 'short' to indicate that we're using short float repr,
973 and 'legacy' if the short float repr isn't available for one
974 reason or another.
975
976 The float repr change involves incorporating David Gay's 'perfect
977 rounding' code into the Python core (it's in Python/dtoa.c). As a
978 secondary consequence, all string-to-float and float-to-string
979 conversions (including all float formatting operations) will be
980 correctly rounded on these platforms.
981
982 See issue 1580 discussions for details of platforms for which
983 this change does not apply.
984
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000985- Issue #5759: float() didn't call __float__ on str subclasses.
986
Georg Brandlabc38772009-04-12 15:51:51 +0000987- The string.maketrans() function is deprecated; there is a new static method
988 maketrans() on the bytes and bytearray classes. This removes confusion about
989 the types string.maketrans() is supposed to work with, and mirrors the
990 methods available on the str class.
991
R. David Murraydc6da8a2009-04-09 22:16:43 +0000992- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

996 to avoid compiler warnings.
997
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000998- Issue #3739: The unicode-internal encoder now reports the number of characters
999 consumed like any other encoder (instead of the number of bytes).

1157 untrackable objects are not tracked by the garbage collector. This can
1158 reduce the size of collections and therefore the garbage collection overhead

1224 (typically /dev/zero under Unix) could crash the interpreter.
1225
Benjamin Peterson59406a92009-03-26 17:10:29 +00001226- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and

1228
Lars Gustäbel42e00912009-03-22 20:34:29 +00001229- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1230 forever on incomplete input. That caused tarfile.open() to hang when used
1231 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1232 partial bzip2 compressed data.
1233
Mark Dickinson79f52032009-03-17 23:12:51 +00001234- Issue #2110: Add support for thousands separator and 'n' type

1252 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00001253 struct.error instead of returning b'\xff\xff\xff\xff'. The
1254 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
1255 have been removed from the struct module.

1274 contained non ascii character on windows.
1275
Benjamin Petersonf5b52242009-03-02 23:31:26 +00001276- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
1277 source has already been decoded into str.
1278
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00001279- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
1280 rotating the object pointer by 4 bits to the right.
1281
Mark Dickinson87ec0852009-02-09 17:15:59 +00001282- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1283 it now forces its argument to double before testing for infinity.
1284
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001285- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1286 returns a non-number type.
1287
Benjamin Peterson87618552009-02-08 15:00:52 +00001288- Issue #5182: Removed memoryview.__str__.

1293 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001294
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001295- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001296 were suppressing all exceptions. These include list() and bytearray().
1297
Mark Dickinson1124e712009-01-28 21:25:58 +00001298- Issue #4707: round(x, n) now returns an integer if x is an integer.
1299 Previously it returned a float.
1300
Antoine Pitroub52ec782009-01-25 16:34:23 +00001301- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1302 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1303 evaluation loop is compiled with a new dispatch mechanism which gives
1304 speedups of up to 20%, depending on the system, on various benchmarks.
1305
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001306- Issue #4874: Most builtin decoders now reject unicode input.

1309 from a string.
1310
Benjamin Peterson05e782f2009-01-19 15:15:02 +00001311- Issue #4991: os.fdopen now raises an OSError for invalid file descriptors.
1312
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001313- Issue #4838: When a module is deallocated, free the memory backing the
1314 optional module state data.
1315
Mark Dickinson8055afd2009-01-17 10:04:45 +00001316- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1317 type to (void *).
1318
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001319- Issue #4935: The overflow checking code in the expandtabs() method common
1320 to str, bytes and bytearray could be optimized away by the compiler, letting
1321 the interpreter segfault instead of raising an error.
1322
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001323- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1324 __next__ method.
1325
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001326- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1327 function no longer attempt to call the __long__ slot to convert an object
1328 to an integer. Only the __int__ and __trunc__ slots are examined.
1329
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001330- Issue #4893: Use NT threading on CE.
1331
Martin v. Löwisec59d042009-01-12 07:59:10 +00001332- Issue #4915: Port sysmodule to Windows CE.
1333
Antoine Pitrouab868312009-01-10 15:40:25 +00001334- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1335 common cases are optimized thanks to a dedicated fast path and a moderate
1336 amount of loop unrolling.
1337
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001338- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1339 collecting the oldest generation) so that allocating lots of objects without
1340 destroying them does not show quadratic performance. Based on a proposal by
1341 Martin von Löwis at
1342 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1343
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001344- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001345 having been closed (for instance, a read() call could return some
1346 previously buffered data). Patch by Dmitry Vasiliev.
1347
Antoine Pitrou05608432009-01-09 18:53:14 +00001348- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1349 flag to work properly. Furthermore, when specifying -u, the text stdout
1350 and stderr streams have line-by-line buffering enabled (the default being
1351 to buffer arbitrary chunks of data).
1352
Raymond Hettinger35631532009-01-09 03:58:09 +00001353- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1354 instead of ints (reducing its size from 4 to 8 times thereby reducing
1355 Python's overall memory).
1356
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001357- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1358 an existing .py counterpart, override the co_filename attributes of all
1359 code objects if the original filename is obsolete (which can happen if the
1360 file has been renamed, moved, or if it is accessed through different paths).
1361 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1362
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001363- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1364 one byte. Also fixes the meaning of len() so that it returns the number of
1365 items, rather than the size in bytes.
1366
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001367- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1368
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001369- Issue #4747: When the terminal does not use utf-8, executing a script with
1370 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1371
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001372- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001373 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001374
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001375- Issue #3680: Reference cycles created through a dict, set or deque iterator
1376 did not get collected.
1377
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001378- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1379 where the tp_hash and tp_dict slots are both NULL.
1380
Georg Brandlccc47b62008-12-28 11:44:14 +00001381- Issue #4759: None is now allowed as the first argument of
1382 bytearray.translate(). It was always allowed for bytes.translate().
1383
Skip Montanaro80072cb2008-12-23 03:51:14 +00001384- Added test case to ensure attempts to read from a file opened for writing
1385 fail.
1386
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001387- Issue #3106: Speedup some comparisons (str/str and int/int).

1390 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1391
Antoine Pitrou621601a2008-12-17 23:18:19 +00001392- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1393 print elapsed times, not only when some objects are uncollectable /
1394 unreachable. Original patch by Neil Schemenauer.
1395
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001396- Issue #3439: Add a bit_length method to int.
1397
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001398- Issue #2173: When getting device encoding, check that return value of
1399 nl_langinfo is not the empty string. This was causing silent build
1400 failures on OS X.
1401
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001402- Issue #4597: Fixed several opcodes that weren't always propagating
1403 exceptions.
1404
1405- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001406 context manager returns a value that cannot be converted to a bool.
1407
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001408- Issue #4445: Replace "sizeof(PyBytesObject)" with
1409 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1410 bytes instances. On a typical machine this saves 3 bytes of memory
1411 (on average) per allocation of a bytes instance.
1412
Christian Heimesa872de52008-12-05 08:26:55 +00001413- Issue #4533: File read operation was dreadfully slow due to a slowly
1414 growing read buffer. Fixed by using the same growth rate algorithm as
1415 Python 2.x.
1416
Antoine Pitrou5504e892008-12-06 21:27:53 +00001417- Issue #4509: Various issues surrounding resize of bytearray objects to
1418 which there are buffer exports (e.g. memoryview instances).
1419
Georg Brandlf9734072008-12-07 15:30:06 +00001420- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1421 method on file objects with closefd=False. The file descriptor is still
1422 kept open but the file object behaves like a closed file. The ``FileIO``
1423 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001424
Antoine Pitroubc420402008-12-07 20:14:49 +00001425- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1431
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001432- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1433 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1434 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1435 of using the replace error handler in PyUnicode_DecodeUTF8().
