886 tests on darwin even when the OS was installed on a case-sensitive
887 filesystem. Also fixed tests that should not be run when
888 sys.dont_write_bytecode is true.

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000895
896Core and Builtins
897-----------------
898
Mark Dickinson865e01a2009-05-07 16:37:01 +0000899- Issue #5914: Add new C API function PyOS_string_to_double, and
900 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
901
Eric Smith741191f2009-05-06 13:08:15 +0000902- Issue #3382: float.__format__, complex.__format__, and %-formatting
903 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
904 affects nan -> NAN and inf -> INF.
905
Mark Hammond5a607a32009-05-06 08:04:54 +0000906- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
907 in all operations, including splitdrive, split, etc. splitunc() now issues
908 a PendingDeprecation warning.
909
Eric Smith63376222009-05-05 14:04:18 +0000910- Issue #5920: For float.__format__, change the behavior with the
911 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
912 to be like 'g' but with at least one decimal point and with a
913 default precision of 12. Previously, the behavior the same but with
914 a default precision of 6. This more closely matches str(), and
915 reduces surprises when adding alignment flags to the empty
916 presentation type. This also affects the new complex.__format__ in
917 the same way.
918
Martin v. Löwis011e8422009-05-05 04:43:17 +0000919- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
920
R. David Murrayb18500d2009-05-04 22:59:07 +0000921- Issue #5890: in subclasses of 'property' the __doc__ attribute was
922 shadowed by classtype's, even if it was None. property now
923 inserts the __doc__ into the subclass instance __dict__.
924
Antoine Pitrou244651a2009-05-04 18:56:13 +0000925- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
926 sequences. Patch by Nick Barnes and Victor Stinner.
927
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000928- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000929
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000930- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
931 received a new method, detach(). detach() disconnects the underlying stream
932 from the buffer or text IO and returns it.
933
Mark Dickinson33841c32009-05-01 15:37:04 +0000934- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
935 floats with absolute value over 1e50. Also remove length
936 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
937 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000938
Eric Smith741191f2009-05-06 13:08:15 +0000939- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000940 format(complex(1, 2./3), '.5') now produces a sensible result.
941
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000942- Issue #5864: Fix empty format code formatting for floats so that it
943 never gives more than the requested number of significant digits.
944
Eric Smith6dc46f52009-04-27 20:39:49 +0000945- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
946 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
947
Eric Smithcc32a112009-04-26 21:35:14 +0000948- Issue #5835: Deprecate PyOS_ascii_formatd.
949
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000950- Issue #4971: Fix titlecase for characters that are their own
951 titlecase, but not their own uppercase.
952
Benjamin Peterson193152c2009-04-25 01:08:45 +0000953- Issue #5283: Setting __class__ in __del__ caused a segfault.
954
Mark Dickinsonad476da2009-04-23 19:14:16 +0000955- Issue #5816: complex(repr(z)) now recovers z exactly, even when
956 z involves nans, infs or negative zeros.
957
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000958- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000959
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000960- Issue #1869 (and many duplicates): make round(x, n) correctly
961 rounded for a float x, by using the decimal <-> binary conversions
962 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
963 consistently agrees with format(x, '.2f').
964
Benjamin Petersonae937c02009-04-18 20:54:08 +0000965- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
966 some builtin types.
967
Eric Smith0923d1d2009-04-16 20:16:10 +0000968- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
969
Eric Smith35e84722009-04-16 20:21:28 +0000970- Issue #5515: str.format() type 'n' combined with commas and leading
971 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000972
973- Implement PEP 378, Format Specifier for Thousands Separator, for
974 floats.
975
Mark Dickinson3370cce2009-04-17 22:40:53 +0000976- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000977 1e11, not 1e12. This avoids printing 13 significant digits in
978 situations where only 12 of them are correct. Example problem
979 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
980 long time.)
981
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000982- Issue #1580: On most platforms, use a 'short' float repr: for a
983 finite float x, repr(x) now outputs a string based on the shortest
984 sequence of decimal digits that rounds to x. Previous behaviour was
985 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000986 Another minor difference is that the new repr switches to
987 exponential notation at 1e16 instead of the previous 1e17; this
988 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000989
990 There's a new sys attribute sys.float_repr_style, which takes
991 the value 'short' to indicate that we're using short float repr,
992 and 'legacy' if the short float repr isn't available for one
993 reason or another.
994
995 The float repr change involves incorporating David Gay's 'perfect
996 rounding' code into the Python core (it's in Python/dtoa.c). As a
997 secondary consequence, all string-to-float and float-to-string
998 conversions (including all float formatting operations) will be
999 correctly rounded on these platforms.
1000
1001 See issue 1580 discussions for details of platforms for which
1002 this change does not apply.
1003
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001004- Issue #5759: float() didn't call __float__ on str subclasses.
1005
Georg Brandlabc38772009-04-12 15:51:51 +00001006- The string.maketrans() function is deprecated; there is a new static method
1007 maketrans() on the bytes and bytearray classes. This removes confusion about
1008 the types string.maketrans() is supposed to work with, and mirrors the
1009 methods available on the str class.
1010
R. David Murraydc6da8a2009-04-09 22:16:43 +00001011- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1012 its clarity and its speed.
1013
Matthias Klose091c7b12009-04-07 13:24:27 +00001014- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1015 to avoid compiler warnings.
1016
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001017- Issue #3739: The unicode-internal encoder now reports the number of characters
1018 consumed like any other encoder (instead of the number of bytes).
1019

1033
Vinay Sajipaffbd872009-06-11 10:11:47 +00001034- Issue #5940: distutils.command.build_clib.check_library_list was not doing

1174
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001175- Issue #4688: Add a heuristic so that tuples and dicts containing only
1176 untrackable objects are not tracked by the garbage collector. This can
1177 reduce the size of collections and therefore the garbage collection overhead
1178 on long-running programs, depending on their particular use of datatypes.

Mark Dickinson87ec0852009-02-09 17:15:59 +00001301- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1302 it now forces its argument to double before testing for infinity.
1303
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001304- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001313
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001314- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001315 were suppressing all exceptions. These include list() and bytearray().

Mark Dickinson1124e712009-01-28 21:25:58 +00001317- Issue #4707: round(x, n) now returns an integer if x is an integer.
1318 Previously it returned a float.
1319
Antoine Pitroub52ec782009-01-25 16:34:23 +00001320- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1321 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1322 evaluation loop is compiled with a new dispatch mechanism which gives
1323 speedups of up to 20%, depending on the system, on various benchmarks.
1324
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001325- Issue #4874: Most builtin decoders now reject unicode input.

1333 optional module state data.
1334
Mark Dickinson8055afd2009-01-17 10:04:45 +00001335- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1336 type to (void *).
1337
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001338- Issue #4935: The overflow checking code in the expandtabs() method common
1339 to str, bytes and bytearray could be optimized away by the compiler, letting
1340 the interpreter segfault instead of raising an error.
1341
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001342- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1343 __next__ method.
1344
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001345- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1346 function no longer attempt to call the __long__ slot to convert an object
1347 to an integer. Only the __int__ and __trunc__ slots are examined.
1348
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001349- Issue #4893: Use NT threading on CE.

1352
Antoine Pitrouab868312009-01-10 15:40:25 +00001353- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1354 common cases are optimized thanks to a dedicated fast path and a moderate
1355 amount of loop unrolling.
1356
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001357- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1358 collecting the oldest generation) so that allocating lots of objects without
1359 destroying them does not show quadratic performance. Based on a proposal by
1360 Martin von Löwis at
1361 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1362
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001363- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001364 having been closed (for instance, a read() call could return some
1365 previously buffered data). Patch by Dmitry Vasiliev.
1366
Antoine Pitrou05608432009-01-09 18:53:14 +00001367- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1368 flag to work properly. Furthermore, when specifying -u, the text stdout
1369 and stderr streams have line-by-line buffering enabled (the default being
1370 to buffer arbitrary chunks of data).
1371
Raymond Hettinger35631532009-01-09 03:58:09 +00001372- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1373 instead of ints (reducing its size from 4 to 8 times thereby reducing
1374 Python's overall memory).
1375
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001376- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1377 an existing .py counterpart, override the co_filename attributes of all
1378 code objects if the original filename is obsolete (which can happen if the
1379 file has been renamed, moved, or if it is accessed through different paths).
1380 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1381
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001382- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1383 one byte. Also fixes the meaning of len() so that it returns the number of
1384 items, rather than the size in bytes.
1385
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001386- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1387
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001388- Issue #4747: When the terminal does not use utf-8, executing a script with
1389 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1390
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001391- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001392 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001393
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001394- Issue #3680: Reference cycles created through a dict, set or deque iterator
1395 did not get collected.
1396
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001397- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1398 where the tp_hash and tp_dict slots are both NULL.
1399
Georg Brandlccc47b62008-12-28 11:44:14 +00001400- Issue #4759: None is now allowed as the first argument of
1401 bytearray.translate(). It was always allowed for bytes.translate().
1402
Skip Montanaro80072cb2008-12-23 03:51:14 +00001403- Added test case to ensure attempts to read from a file opened for writing
1404 fail.

1410
Antoine Pitrou621601a2008-12-17 23:18:19 +00001411- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1412 print elapsed times, not only when some objects are uncollectable /
1413 unreachable. Original patch by Neil Schemenauer.
1414
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001415- Issue #3439: Add a bit_length method to int.
1416
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001417- Issue #2173: When getting device encoding, check that return value of
1418 nl_langinfo is not the empty string. This was causing silent build
1419 failures on OS X.
1420
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001421- Issue #4597: Fixed several opcodes that weren't always propagating
1422 exceptions.
1423
1424- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001425 context manager returns a value that cannot be converted to a bool.
1426
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001427- Issue #4445: Replace "sizeof(PyBytesObject)" with
1428 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1429 bytes instances. On a typical machine this saves 3 bytes of memory
1430 (on average) per allocation of a bytes instance.
1431
Christian Heimesa872de52008-12-05 08:26:55 +00001432- Issue #4533: File read operation was dreadfully slow due to a slowly
1433 growing read buffer. Fixed by using the same growth rate algorithm as
1434 Python 2.x.
1435
Antoine Pitrou5504e892008-12-06 21:27:53 +00001436- Issue #4509: Various issues surrounding resize of bytearray objects to
1437 which there are buffer exports (e.g. memoryview instances).
1438
Georg Brandlf9734072008-12-07 15:30:06 +00001439- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1440 method on file objects with closefd=False. The file descriptor is still
1441 kept open but the file object behaves like a closed file. The ``FileIO``
1442 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001443
Antoine Pitroubc420402008-12-07 20:14:49 +00001444- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1452 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1453 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1454 of using the replace error handler in PyUnicode_DecodeUTF8().
