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

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

882
Mark Dickinson865e01a2009-05-07 16:37:01 +0000883- Issue #5914: Add new C API function PyOS_string_to_double, and
884 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
885
Eric Smith741191f2009-05-06 13:08:15 +0000886- Issue #3382: float.__format__, complex.__format__, and %-formatting
887 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
888 affects nan -> NAN and inf -> INF.
889
Mark Hammond5a607a32009-05-06 08:04:54 +0000890- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
891 in all operations, including splitdrive, split, etc. splitunc() now issues
892 a PendingDeprecation warning.
893
Eric Smith63376222009-05-05 14:04:18 +0000894- Issue #5920: For float.__format__, change the behavior with the
895 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
896 to be like 'g' but with at least one decimal point and with a
897 default precision of 12. Previously, the behavior the same but with
898 a default precision of 6. This more closely matches str(), and
899 reduces surprises when adding alignment flags to the empty
900 presentation type. This also affects the new complex.__format__ in
901 the same way.

Benjamin Petersond2e0c792009-05-01 20:40:59 +0000914- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
915 received a new method, detach(). detach() disconnects the underlying stream
916 from the buffer or text IO and returns it.

Mark Dickinson33841c32009-05-01 15:37:04 +0000918- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
919 floats with absolute value over 1e50. Also remove length
920 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
921 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +0000923- Issue #1588: Add complex.__format__. For example,

925
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000926- Issue #5864: Fix empty format code formatting for floats so that it

Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000942- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000943
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000944- Issue #1869 (and many duplicates): make round(x, n) correctly
945 rounded for a float x, by using the decimal <-> binary conversions
946 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
947 consistently agrees with format(x, '.2f').
948
Benjamin Petersonae937c02009-04-18 20:54:08 +0000949- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

953
Eric Smith35e84722009-04-16 20:21:28 +0000954- Issue #5515: str.format() type 'n' combined with commas and leading
955 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000956
957- Implement PEP 378, Format Specifier for Thousands Separator, for
958 floats.
959
Mark Dickinson3370cce2009-04-17 22:40:53 +0000960- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000961 1e11, not 1e12. This avoids printing 13 significant digits in
962 situations where only 12 of them are correct. Example problem
963 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
964 long time.)
965
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000966- Issue #1580: On most platforms, use a 'short' float repr: for a
967 finite float x, repr(x) now outputs a string based on the shortest
968 sequence of decimal digits that rounds to x. Previous behaviour was
969 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000970 Another minor difference is that the new repr switches to
971 exponential notation at 1e16 instead of the previous 1e17; this
972 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000973
974 There's a new sys attribute sys.float_repr_style, which takes
975 the value 'short' to indicate that we're using short float repr,
976 and 'legacy' if the short float repr isn't available for one
977 reason or another.
978
979 The float repr change involves incorporating David Gay's 'perfect
980 rounding' code into the Python core (it's in Python/dtoa.c). As a
981 secondary consequence, all string-to-float and float-to-string
982 conversions (including all float formatting operations) will be
983 correctly rounded on these platforms.
984
985 See issue 1580 discussions for details of platforms for which
986 this change does not apply.
987
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000988- Issue #5759: float() didn't call __float__ on str subclasses.
989
Georg Brandlabc38772009-04-12 15:51:51 +0000990- The string.maketrans() function is deprecated; there is a new static method
991 maketrans() on the bytes and bytearray classes. This removes confusion about
992 the types string.maketrans() is supposed to work with, and mirrors the
993 methods available on the str class.

1160 untrackable objects are not tracked by the garbage collector. This can
1161 reduce the size of collections and therefore the garbage collection overhead

1227 (typically /dev/zero under Unix) could crash the interpreter.
1228
Benjamin Peterson59406a92009-03-26 17:10:29 +00001229- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and

1231
Lars Gustäbel42e00912009-03-22 20:34:29 +00001232- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1233 forever on incomplete input. That caused tarfile.open() to hang when used
1234 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1235 partial bzip2 compressed data.

Mark Dickinsonb40b9472009-03-29 16:58:21 +00001256 struct.error instead of returning b'\xff\xff\xff\xff'. The
1257 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
1258 have been removed from the struct module.

1277 contained non ascii character on windows.
1278
Benjamin Petersonf5b52242009-03-02 23:31:26 +00001279- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
1280 source has already been decoded into str.
1281

1283 rotating the object pointer by 4 bits to the right.
1284
Mark Dickinson87ec0852009-02-09 17:15:59 +00001285- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1286 it now forces its argument to double before testing for infinity.
1287
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001288- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1289 returns a non-number type.
1290
Benjamin Peterson87618552009-02-08 15:00:52 +00001291- Issue #5182: Removed memoryview.__str__.

1296 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001297
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001298- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001299 were suppressing all exceptions. These include list() and bytearray().
1300
Mark Dickinson1124e712009-01-28 21:25:58 +00001301- Issue #4707: round(x, n) now returns an integer if x is an integer.
1302 Previously it returned a float.
1303
Antoine Pitroub52ec782009-01-25 16:34:23 +00001304- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1305 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1306 evaluation loop is compiled with a new dispatch mechanism which gives
1307 speedups of up to 20%, depending on the system, on various benchmarks.
1308
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001309- Issue #4874: Most builtin decoders now reject unicode input.

1315
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001316- Issue #4838: When a module is deallocated, free the memory backing the
1317 optional module state data.
1318
Mark Dickinson8055afd2009-01-17 10:04:45 +00001319- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1320 type to (void *).
1321
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001322- Issue #4935: The overflow checking code in the expandtabs() method common
1323 to str, bytes and bytearray could be optimized away by the compiler, letting
1324 the interpreter segfault instead of raising an error.
1325
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001326- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1327 __next__ method.
1328
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001329- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1330 function no longer attempt to call the __long__ slot to convert an object
1331 to an integer. Only the __int__ and __trunc__ slots are examined.
1332
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001333- Issue #4893: Use NT threading on CE.
1334
Martin v. Löwisec59d042009-01-12 07:59:10 +00001335- Issue #4915: Port sysmodule to Windows CE.
1336
Antoine Pitrouab868312009-01-10 15:40:25 +00001337- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1338 common cases are optimized thanks to a dedicated fast path and a moderate
1339 amount of loop unrolling.
1340
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001341- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1342 collecting the oldest generation) so that allocating lots of objects without
1343 destroying them does not show quadratic performance. Based on a proposal by
1344 Martin von Löwis at
1345 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1346
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001347- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001348 having been closed (for instance, a read() call could return some
1349 previously buffered data). Patch by Dmitry Vasiliev.
1350
Antoine Pitrou05608432009-01-09 18:53:14 +00001351- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1352 flag to work properly. Furthermore, when specifying -u, the text stdout
1353 and stderr streams have line-by-line buffering enabled (the default being
1354 to buffer arbitrary chunks of data).
1355
Raymond Hettinger35631532009-01-09 03:58:09 +00001356- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1357 instead of ints (reducing its size from 4 to 8 times thereby reducing
1358 Python's overall memory).
1359
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001360- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1361 an existing .py counterpart, override the co_filename attributes of all
1362 code objects if the original filename is obsolete (which can happen if the
1363 file has been renamed, moved, or if it is accessed through different paths).
1364 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1365
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001366- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1367 one byte. Also fixes the meaning of len() so that it returns the number of
1368 items, rather than the size in bytes.
1369
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001370- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1371
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001372- Issue #4747: When the terminal does not use utf-8, executing a script with
1373 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1374
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001375- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001376 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001377
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001378- Issue #3680: Reference cycles created through a dict, set or deque iterator
1379 did not get collected.
1380
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001381- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1382 where the tp_hash and tp_dict slots are both NULL.
1383
Georg Brandlccc47b62008-12-28 11:44:14 +00001384- Issue #4759: None is now allowed as the first argument of
1385 bytearray.translate(). It was always allowed for bytes.translate().
1386
Skip Montanaro80072cb2008-12-23 03:51:14 +00001387- Added test case to ensure attempts to read from a file opened for writing
1388 fail.
1389
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001390- Issue #3106: Speedup some comparisons (str/str and int/int).

Antoine Pitrouf289ae62008-12-18 11:06:25 +00001392- Issue #2183: Simplify and optimize bytecode for list, dict and set
1393 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1394
Antoine Pitrou621601a2008-12-17 23:18:19 +00001395- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1396 print elapsed times, not only when some objects are uncollectable /
1397 unreachable. Original patch by Neil Schemenauer.
1398
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001399- Issue #3439: Add a bit_length method to int.
1400
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001401- Issue #2173: When getting device encoding, check that return value of
1402 nl_langinfo is not the empty string. This was causing silent build
1403 failures on OS X.
1404
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001405- Issue #4597: Fixed several opcodes that weren't always propagating
1406 exceptions.
1407
1408- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001409 context manager returns a value that cannot be converted to a bool.
1410
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001411- Issue #4445: Replace "sizeof(PyBytesObject)" with
1412 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1413 bytes instances. On a typical machine this saves 3 bytes of memory
1414 (on average) per allocation of a bytes instance.
1415
Christian Heimesa872de52008-12-05 08:26:55 +00001416- Issue #4533: File read operation was dreadfully slow due to a slowly
1417 growing read buffer. Fixed by using the same growth rate algorithm as
1418 Python 2.x.
1419
Antoine Pitrou5504e892008-12-06 21:27:53 +00001420- Issue #4509: Various issues surrounding resize of bytearray objects to
1421 which there are buffer exports (e.g. memoryview instances).
1422
Georg Brandlf9734072008-12-07 15:30:06 +00001423- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1424 method on file objects with closefd=False. The file descriptor is still
1425 kept open but the file object behaves like a closed file. The ``FileIO``
1426 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001427
Antoine Pitroubc420402008-12-07 20:14:49 +00001428- Issue #4569: Interpreter crash when mutating a memoryview with an item size
1429 larger than 1.

1434
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001435- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1436 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1437 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1438 of using the replace error handler in PyUnicode_DecodeUTF8().
